The principal author was confronted few years ago with the case of a 38-year-old woman with a 5-month history of ill-defined L5 sciatic pain that was referred to an orthopaedic department for investigation and eventual surgical treatment for what was suspected to be herniated disc-related sciatica. Removal of her enlarged uterus found unexpectedly close to the sacroiliac joint upon lumbar MRI abolished her symptoms. Review of the literature showed that the lumbosacral trunk is vulnerable to pressure from any abdominal mass originating from the uterus and the ovaries. Physiological processes in the female patient and gynaecological diseases may be the source of sciatica, often not readily searched for, leading to fruitless investigations and surgical treatments. The aim of the paper is to highlight gynaecological and obstetrical causes of sciatica and sciatica-like symptoms. To prevent unproductive expenses and morbidity, a thorough gynaecological examination should be done even though neurological examination may be suggestive of a herniated intervertebral disc, and the cyclic pattern of pain related to menses should be routinely asked for.

Sciatica secondary to nerve root compression usually presents with well-defined distal motor and sensory involvement and reflex changes. As the dura, nerve roots, and their sleeves are sensitive to pain, dural mobility tests may help in the diagnosis of sciatica [41, 66, 79, 96]. In lumbosacral plexopathy, several roots may be involved with a patchy distribution with no clear anatomical localisation [22, 30].

Disc prolapse is by far the most popular and common cause of sciatica with lesions occurring most often at L4-L5 and L5-S1 segments [79]. The vulnerability of the lumbosacral plexus (L4-L5 roots) to compression by uterine and pelvic tumours has led to misdiagnosis and ineffective surgeries in the past. This article attempts to give to the reader an overview of the literature so as to prevent such misadventures and help in prompt diagnosis and management.

Material and methods

The courses of the lumbosacral plexus and sciatic nerve were reviewed with special emphasis on their relation to female pelvic organs. The Medline database was screened through the period 1966—2004 February using sciatica, sciatica and female patients, or sciatica and aetiology as key words. Articles describing sciatica related to gynaecological, obstetrical, or anatomical variations in the female patient were selected and studied. Articles published before 1966 and referred to in articles were obtained and carefully studied as well.


The first three and most of the fourth lumbar ventral rami descend laterally into the psoas major muscle and form the lumbar plexus [127, 171]. The smaller moiety of the fourth joins the fifth as the lumbosacral trunk that appears at the medial margin of the psoas major, descending over the pelvic brim anterior to the sacroiliac joint to join the first three sacral rami and part of S4 forming the sacral plexus (Fig. 1).

The sacral plexus adjoins the posterior pelvic wall anterior to the piriformis muscle, posterior to the internal iliac vessels, the ureter, and the sigmoid colon to the left and the terminal ileal coils on the right. The sciatic nerve is the continuation of the upper band of the sacral plexus. It leaves the pelvis via the greater sciatic foramen usually situated between the deeper gemelli and obturator internus and the superficial piriformis muscles and descends along the back of the thigh dividing into the tibial and common (fibular) peroneal nerves. The close proximity of the piriformis makes the sciatic nerve vulnerable to irritation and entrapment [11]. Sometimes, the common peroneal portion of the sciatic nerve, and rarely the entire nerve, pierces through the piriformis muscle that may be bipartite entrapping the sciatic nerve [32, 157].

Seventy-five articles in English, French, German, Spanish, and Danish reporting 127 cases with unilateral or bilateral sciatica or leg pain caused by a gynaecological or an obstetrical disorder were found. Endometriosis was the commonest cause (66) followed by pregnancy and labour related sciatica (40), fibroids (4), sacral osteophytes (3), endosalpingiosis (3), vaginal needle intervention (2), pelvic metastasis (2), piriformis related sciatica (2) and one case each related to adenomyosis, intra-uterine device, haematocolpos, tuboovarian abscess, and retroverted uterus.

Sciatica in pregnancy

Back pain is reported by as many as 50–76% of all pregnant women, generally as a musculoskeletal response to the shifting centre of gravity, weight gain and hormonal factors responsible for ligamentous relaxation and changes in the pelvic joints [99, 165, 170].

At term, the gravid uterus averages about 5 l and weighs approximately 1,100 gm to be added to the average infant birth weight of 3,000–3,600 gm [37]. The largest baby recorded in the literature was a stillborn female weighing 11,340 gm [36]. Direct pressure on nerve roots and ischemia of neural elements due to uterine pressure on aorta and vena cava when lying on the back may result in back pain with radiation to the legs [8].

Herniated intervertebral disc disease: The approximate frequency of herniated disc disease (HDD) as a cause of low back pain during pregnancy or in the postpartum period has been estimated at 1 for 10,000 pregnancies with unilateral sciatica in 41% and bilateral sciatica in 21% [102, 116]. MRI without the use of gadolinium chelates now allows detailed evaluation of HDD without exposure of the fetus to the potential negative effects of ionising radiation [65, 104]. Abnormal disk encountered in asymptomatic pregnant women as well as the high prevalence of anatomic abnormalities discovered in asymptomatic people highlight the importance of careful correlation of symptoms and findings at MRI [20, 92, 104, 170]. In the presence of symptomatic HDD, elective caesarean section may be the preferred route of delivery with the anticipation that increasing epidural venous pressure, which is an indirect measure of CSF pressure, could precipitate progressive neurological dysfunction [103]. However, vaginal delivery can be carried under epidural anaesthesia as the elevations in both pressures are rather a product of the reflex responses of skeletal muscles to pain than contractions of the uterine musculature itself [68, 117].

Sciatica secondary to hyperemesis gravidarum has been described in a 34-year-old woman who presented at 9 weeks gestation with severe left leg pain [68]. Whether this resulted in a fresh disc herniation or worsened a pre-existing disc disease is not clear. Severe vomiting can be expected to trigger sciatica in the pregnant patient.

Fractures of the sacrum due to bone deficiency are not extremely uncommon in women over 60 years of age, with no trauma identified in two-thirds of the cases [60]. Taking into consideration the shifting centre of gravity, changes in the pelvic joints during pregnancy, and unaccustomed stress, we cannot exclude that some patients have sacral stress fractures such as those encountered in athletes known to produce sciatica or symptoms mimicking sciatica [114, 115]. Few cases of sacral fracture related to pregnancy have been reported in whom bone mineral density was not necessarily low [23, 74, 142, 145, 159]. Back pain, the commonest symptom related to pregnancy-associated osteoporosis, buttock pain and vertebral fracture seem to occur more often during the first pregnancy or shortly after delivery [91, 92, 94, 152]. The prognosis is generally good and recurrence rare. In some patients, the condition may be pre-existing or secondary to previous corticosteroid therapy, heparin treatment, anorexia nervosa, osteogenesis imperfecta or coeliac disease. In others, there is no identifiable cause [97, 152].

Sciatica during labour

In the lithotomy position, the sciatic nerve may be mechanically stretched and compressed in the gluteal region. The gluteal compartment syndrome, commonly associated with sciatic nerve compression, usually results from prolonged immobility without frequent repositioning and can be encountered with short procedure in this position [47, 141]. It has not been described during delivery. The mainstay of treatment consists of fasciotomy and debridment [82]. A pure L5 lesion with foot drop may result from direct pressure on the common peroneal nerve due to incorrectly positioned leg stirrups on the obstetrical table [2, 21, 52, 86, 109, 155, 162. Prevention consists in positioning the knee and hip joints well flexed and avoiding extreme external rotation of the hips [6]. Treatment consists of rest, splint, or cast. The lithotomy position may also result in femoral nerve neuropraxia with weakness of quadriceps muscle and hip flexion [162]. Subsequent pregnancies should be terminated by caesarean section if axons have been crushed previously, a trial of vaginal delivery fails, or the fetus is too large [52].

The incidence of obstetric neuropathy during vaginal labour has been evaluated between 1 for 2,530 and 1 for 6,400 pregnancies [29, 84]. Neuropathy of the sciatic nerve can be caused by continuous pressure of the presenting part on the lumbosacral trunk as it crosses the pelvic brim during a prolonged labour [134]. Abnormal presentations (breech, occiput posterior, and occiput transverse) or craniosynostosis resulting in the inability of the fetal vertex to mould during labour may also be contributing factors [72]. One or two days after delivery, the patient presents with a burning, aching pain frequently associated with motor impairment characteristically unilateral on the side opposite the presentation of the vertex [53]. The disorder is usually a neuropraxia that can be expected to recover spontaneously in up to 3–4 months. Obturator, femoral, lateral femoral cutaneous nerve or pudendal plexus injury may accompany sciatic nerve injury [162]. Occasionally bilateral involvement occurs. Nerve suffering can also be caused by direct damage by the edges of the obstetric forceps during rotation procedures [12, 29, 71]. The typical patient in this case is a short woman carrying a large fetus whose labour is prolonged by cephalopelvic disproportion [53, 86].

The piriformis syndrome has been documented for more than 50 years and is now a well-known cause of sciatica [157]. Mechanical compression of the sciatic nerve has been reported following a piriformis haematoma after prolonged labour and a piriformis abscess after epidural anaesthesia and forceps delivery [87, 95, 100]. Sciatica associated with occasional dyspareunia secondary to sciatic nerve entrapment within a bipartite piriformis has also been described [32]. In patients presenting with sciatica without evidence of disc disease, and with prominent pain and local tenderness over the muscle exacerbated on passive hip movement in flexion, adduction, and internal rotation, one should consider piriformis muscle as a source. This can be easily confirmed by enhanced magnetic resonance, computed tomographic imaging, or electromyography. Piriformis syndrome per se may be successfully treated by surgery, physical therapy, and botulinum toxin injections [61].

The mechanisms whereby epidural analgesia may legitimately be associated with neurological damage may be summarised as neurotoxic, vascular, compressive, infective, and traumatic [151]. Trauma from epidural placement of the needle affects only a single nerve root in contrast to other complications which affects several roots. This can happen by placing the needle well off-centre unless there is unsuspected scoliosis. Catheters may impinge on a nerve root producing paraesthesia on insertion with symptoms which may persist occasionally for a variable time postpartum. When the epidural injection is technically difficult, the prolonged sitting position may result in sciatic nerve compression and/or ischemia in the parturient. A large volume epidural injection may precipitate an ischemic/compressive nerve root lesion in the presence of vascular malformation, disc protrusion, or stenosis of the vertebral canal [151]. The neurotoxic effect of the local anaesthetic may involve rootlets of all anaesthetised nerves and is thus bilateral [21]. In a survey in the North West Thames Region of 48,066 women delivering including 13,636 regional blocks, a single case of paraesthesia of nerve root distribution without any neurological signs could be attributed to epidural analgesia [84]. Another survey of 11,701 women who delivered in Birmingham showed that 26 women had numbness or tingling in the lower back, buttocks and leg, of whom 23 had epidural anaesthesia [112]. Effective epidural analgesia may mask the symptoms of an exacerbated pre-existing disk prolapse or a de novo disk prolapse during labour [64]. Postpartum neurological symptoms should not be attributed to the use of epidural analgesia in labour without first ruling out other causes.

Sciatic palsy may reveal itself after caesarean section. The sitting position during epidural anaesthesia in thin patients, the lateral tilt position during delivery with or without severe hypotension may precipitate sciatic nerve injury after it leaves the sciatic notch [151, 163].

Sciatica secondary to pathological conditions

Leiomyomas (fibroids, myomas or fibromyomas) are the most common solid benign masses of uterine origin frequently palpated within the pelvis. They rarely appear before puberty and after menopause and are present in at least 20% of white women over the age of 30 and nearly 50% of black women [168]. Disturbance in the menstrual period with pain, often crampy in nature or labour-like, are the most striking symptoms associated with myoma. They may cause a feeling of pelvic heaviness or produce pressure symptoms on surrounding structures such as urinary frequency, stress incontinence, retention, constipation, and difficult defecation. The calcified myoma is palpable as a stony hard mass within the pelvis and is readily viewed and identified by x-ray film. Without symptoms, myomas are managed by observation as they usually regress after the menopause. Four cases of sciatica caused by direct compression of the lumbosacral trunk by the myomatous growths have been reported [1, 19, 78, 106].

The incidence of endometriosis varies from 5 to 20% of all women of reproductive age, more than 20% of whom present with infertility [40]. Affected teenagers and previously fertile women most commonly harbour functional hormone dependant endometrial tissue over the surface of and within the ovaries. Endometriosis can compress the sciatic nerve within the pelvis, at the sciatic notch, in the gluteal region distal to the notch, or within the sheath of the sciatic nerve [155, 167]. The commonest site is the sciatic notch where fibrosis, organised haematoma and endometrial tissue involving the muscles envelop the sciatic and sometimes the gluteal nerves [17]. Hip pain due to endometriosis in a lumbar foramen has been described [175]. Typically, patients present with pain in the hip and the buttock radiating in the leg and foot that has its onset few days before menstruation and becomes progressively more severe, subsiding 2 or 3 days to 2 weeks after cessation of menstruation; hence, the term cyclical or catamenial sciatica. As time goes on, the duration of sciatic discomfort may increase until it is constantly present with excruciating exacerbation during menses [14, 25, 26, 28, 35, 39, 44, 45, 49, 50, 55, 58, 63, 69, 73, 75, 77, 113, 124, 133, 140, 143, 144, 146, 147, 154, 156, 158, 160, 164, 167]. Diagnosis is usually late. Vercellini et al. [166] found that two-thirds of patients with sciatic nerve endometriosis had right-side lesions. Surgical exploration of the sciatic nerve is not thought to be necessary in most cases because of the danger of a more permanent damage to the nerve [18]. Remission of symptoms during pregnancy has been reported [38]. Catamenial sciatica responds well to gonadotropin-releasing hormone analogues [18, 25, 39, 46, 58, 69, 81, 90, 124, 138, 158]. Pelvic endometriosis is accessible to laparoscopic excision.

Adenomyosis, endometrial glands and stroma found within the myometrium, is primarily a disorder of parous women over age 30 and occurs infrequently in nulliparas. The incidence varies widely (8–40%) in routine sampling of surgically removed uteri which show co-associated myomas in 36–50% of the cases [57, 105]. About 30% of myomas are asymptomatic and are discovered accidentally. The disorder manifests itself classically by progressive menstrual bleeding, increasingly painful dysmenorrhoea, and a gradually enlarging, tender uterus. The correct preoperative diagnosis is made in somewhat less than one-third of all instances. Women near the menopause may be managed for an appreciable time with analgesics alone, anticipating resolution of symptoms following cessation of menses. Hysterectomy is the only completely satisfactory treatment for adenomyosis. One case of sciatica caused by adenomyosis has been reported in a 38-year-old patient whose uterus was found in the vicinity of the right lumbosacral trunk [4].

Three cases of leg pain related to endosalpingiosis confirmed at laparoscopy have been described by Vilos et al. [167]. Symptoms resolved in two and remained unchanged in one in spite of prompt treatment.

Sciatica secondary to iatrogenic trauma

During abdominal surgical procedures, peripheral nerve injury is usually related to poor positioning of the patient, surgical dissection, or excessive pressure exerted by the surgeons [128]. In most cases, sensory or motor deficits are found as the patient emerges from anaesthesia. When a Pfannenstiel incision is chosen, the ilio-inguinal nerve may be severed or ligated, resulting in permanent numbness or burning sensation in the area of nerve distribution [88]. The sciatic nerve and the lumbosacral plexus may be injured in the control of bleeding from the hypogastric vessels [169]. The “jack-knife” position utilised in vaginal and retropubic surgery, or in diagnostic laparoscopy, is prevented by avoiding hyperextension and excessive lateral rotation of the legs and by fully supporting the back of the knees while they are suspended in stirrups. During radical hysterectomy and pelvic sidewall node dissection (Wertheim-Meigs hysterectomy) for carcinoma of the cervix, the damage most likely to occur is to the genito-femoral and the obturator nerves. Less frequently, the femoral, peroneal, or sciatic nerves may be damaged [126].

Vaginal operations have occasionally been complicated by sciatic neuropathy, possibly because of stretching of the nerve, rather than by direct pressure [109, 136]. Two cases of gluteal artery pseudo aneurysm with sciatic nerve compression have been reported following transvaginal ultrasound-guided follicle aspiration for primary infertility [173] and transvaginal needle biopsy for endometriosis [132].

To the best of our knowledge, no neurological injuries secondary to operative laparoscopy have been reported yet.

During intra-muscular injection, the postulated mechanisms of injury to the peripheral nerves include direct needle trauma, secondary constriction by scar and direct nerve fibre damage by neurotoxic chemicals in the injected agent. The sciatic nerve is particularly vulnerable for such trauma during labour, for example [6].

Sciatica related to anatomical variations

Imperforate hymen manifests itself at puberty and adolescence often with a history of vague abdominal pain with approximately monthly exacerbation. [137]. Most cases are not diagnosed until a haematocolpos forms. Examination shows a low abdominal mass and the presence of a distended, often bluish in colour imperforate hymen. Two cases of low back pain [76, 108] and one case of sciatica secondary to haematocolpos have been reported. The accurate diagnosis in a 15-year-old girl was made after 1 year of cyclic low back pain radiating posteriorly down the legs [111]. A cruciate incision to the hymen resulted in evacuation of 1 l of altered blood under pressure and immediate resolution of her symptoms.

It has been suggested that a retroverted uterus may cause low back pain. A 47-year-old woman whose womb was found retroverted in direct contact with and mildly adherent to the anterior aspect of the sacroiliac joint reported sciatic pain with L5 and S1 root involvement [129]. Abdominal hysterectomy abolished the symptoms.

The posteriorly situated colon is a rare variant found in 1% of people, more commonly women, in which the colon extends so medially that it abuts the ventral rami leading to potential compression of these during gaseous and faecal distension [48, 149]. McPherson et al. [119] described a 42-year-old woman with 4-year history of intermittent low back and left buttock pain associated with a positive straight leg raising test whose left L4 and L5 ventral rami were adjacent to the descending colon passing posterior to the left psoas and anterior to the quadratus lumborum and iliacus muscles.

Miscellaneous causes of sciatica

Albeit major changes in their designs, intrauterine devices (IUD) have a high morbidity [34]. Perforation of the uterine wall has an incidence from 0.0 to 8.7/1,000 insertions and may result from technical faults during insertion, uterine contractions after insertion, and certain anatomic abnormalities which may be considered as relative contraindications [34]. Fundal perforation at the time of insertion is accompanied with pain and bleeding. Later, it may be “silent” and recognised on a subsequent follow-up when IUD is found displaced, the string absent or the patient obviously pregnant. IUD migration complicated by ileosigmoid fistula, small and large bowel perforation, appendicitis, peritonitis, rupture of the uterus in subsequent pregnancy, perforation of the bladder and obstructive nephropathy has been reported. Review of the lumbosacral roentgenograms of a 25-year-old woman who presented with right-sided sciatica revealed an IUD in the vicinity of the right psoas muscle [56]. Symptoms improved immediately after its removal by laparoscopy from the posterior cul-de-sac where it was found anterior to the lumbosacral nerve roots.

Tuboovarian abscess (TOA) is an end-stage process of acute pelvic inflammatory disease caused by micro-organisms colonising the endocervix ascending to the endometrium and the fallopian tubes. Traditionally, TOA is diagnosed when a patient with pelvic pain and fever presents with a pelvic mass. One case of sciatica secondary to a TOA has been reported in a 25-year-old patient presenting with low grade fever and severe right sciatic pain after a fall 3 weeks before admission [7]. She responded well to intravenous anti-microbial therapy as do approximately 75% of women with TOA.

Osteophytes at the sacroiliac joints secondary to the stress produced by the mobility of these joints to facilitate parturition are usually found at the anteroinferior portion of the joint [154]. Three patients have been reported to present restricted straight leg raising tests with tenderness at the level of the sciatic notch [101]. One had evidence of L5 root suffering, another had S1 root suffering while in the third, neurological examination was normal. They responded to local anaesthetic infiltration but two needed further surgical removal of the osteophyte.

Extra-spinal involvement of the sciatic nerve by primary malignant tumours or secondary metastasis has been reported at the level of the sacroiliac joint by bone metastasis from a breast cancer and in the region of the greater sciatic foramen by endometrial carcinoma [27, 33].


Disc prolapse is by far the most popular and common cause of sciatica [2, 24, 51, 122, 123, 139]. The annual incidence is about 5% per year in 20–40-year-olds with lesions occurring most often at L4-L5 and L5-S1 segments [79]. Newer imaging tools and refinements of electrophysiological studies have identified many other lesions as potential causes: hip diseases [67, 107, 110, 150] pelvic diseases [3, 13, 31, 83, 120, 148, 172] spinal canal disease [9, 15, 54, 62, 70, 89, 125, 130, 131, 135] central nervous system tumours [5, 16, 176] vascular malformation and disease [42, 43, 85, 121] and infectious disease [93, 161].

Differentiating sciatica due to lumbar disc disease from those due to other pathologic conditions can be a difficult diagnostic dilemma. In the female patient, when imaging of the spinal canal is equivocal, CT or MRI evaluation of the greater sciatic foramen can be helpful [17, 32, 33]. Direct compression of ventral rami or the lumbosacral plexus by an enlarged uterus may result in sciatica with or without neurological deficit. The cyclic nature of pain makes the diagnosis of catamenial sciatica highly probable during the child-bearing age and imperforate hymen with haematocolpos in the teenage girl [111]. Anatomical variations and medical interventions may unusually present with sciatica.

The main presenting symptom of female sex related sciatica was in this review L3, L5, or S1 radicular pain. Lumbosacral plexopathy pain, diffuse leg pain and hip pain with or without neurological deficit were also reported (Table 1).

In the largest endometriosis group, diagnosis was made correctly on clinical basis in eight patients (12%) as the history of endometriosis and/or the cyclic pattern of symptoms were suggestive [46, 58, 75, 81, 90]. In the others, diagnosis was delayed in average 3.8 years (1 month–15 years) [80]. MRI suggested the diagnosis in three cases [45, 81, 174]. During pregnancy, labour, and the post-partum, diagnosis was either immediate within few days when sciatica was related to a herniated disc, or was delayed with sacral stress fractures up to 4.5 months [159]. For the other cases, diagnosis was made within 1 year except for one case with sacroiliac osteophytosis, which was diagnosed 2 years after the onset of symptoms [103]. Intervertebral disk disease was suspected in 49 patients (38.5%) [1, 2, 4, 7, 10, 14, 17, 18, 27, 28, 32, 35, 45, 50, 63, 69, 77, 80, 98, 101, 111, 113, 124, 129, 133, 138, 143, 146, 147, 152, 156, 160, 174, 175] and led to surgical procedures without any benefit in five patients [10, 18, 77, 80, 143, 164]. Other tentative diagnoses were low back pain and/or lumbar arthritis, abdominal adhesions, peroneal palsy, piriformis syndrome, uterine fibroid, lumbosacral radiculopathy and local buttock problem. Psychiatric illness was suspected during the course of the illness in three patients [80, 98, 164]. Some patients had one or more myelogram, CT, MRI, EMG, or CSF analysis and even barium enema studies. Some were seen by several specialists before the final diagnosis was made, Zangger’s case being the most illustrative as the patient was seen by 17 physicians before endometriosis was diagnosed [175]. Hysterectomy abolished symptoms in five patients (4%) [1, 4, 19, 106, 129].

The cases reported by Baker et al. [10], Björnsson [18], Hibbard et al. [80], Kohorn [98], Laman et al. [106] and Vaisberg [164] are illustrative of the difficulty one may face before correct diagnosis is made in the female patient presenting with leg pain.


In any case of sciatica in a female patient, it seems cogent to the diagnosis that a detailed menstrual history be taken, bearing in mind the possibility that an endometrial implant on or nearby the sciatic nerve, a heavy and/or voluminous uterus or other gynaecological diseases may result in recurring leg pain, weakness, and/or sensory loss. The cyclic pattern of sciatic pain is highly suggestive of endometriosis and should be searched for systematically, and considered in the differential diagnosis.

The search for a gynaecological/obstetric aetiology for pain should be considered even though imaging techniques reveal either a herniated disc or other pathologic conditions of the spine which correlate with the symptoms [164].

In patients presenting with sciatica without evidence of disc disease, the evaluation should not be considered complete without scanning the course of the nerve through the greater sciatic foramen. With prominent pain on passive hip movement, one should consider pelvic muscle disease easily confirmed by enhanced magnetic resonance or computed tomographic imaging.
