Abstract
Background
We describe a new surgical technique for arthrodesis of the first tarso-metatarsal (TMT) joint using an intraosseous fixation device and the early results including patient-reported outcome measures (PROMS).
Materials and Methods
Seventeen consecutive procedures with this method were included. Indication for surgery was hallux valgus. The average age was 42 years (range 26–65). PROMS were collected and the patients were asked to fill out a satisfaction questionnaire. A retrospective review of radiographs and electronic medical notes was conducted.
Results
Overall fusion rate was 94%. Complications included a case of failed fusion, a superficial wound infection and a deep vein thrombosis (DVT). At a mean follow-up of 24 months (range 10–38) radiographic results demonstrated significant improvement in the intermetatarsal angle or IMA (11.7 ± 2.8 degrees to 6.9 ± 2.4 degrees, P < 0.001) and hallux valgus angle or HVA (28.1 ± 7.3 degrees to 12.2 ± 4.3 degrees, P < 0.001). The mean visual analog scale (VAS) score improved significantly from a mean of 7.6 (SD 0.85) preoperatively, to a mean of 2.1 (SD 1.83) post-operatively (P < 0.0001). The Manchester–Oxford Foot Questionnaire (MOXFQ) significantly improved from a mean of 35.8 (SD 10.2), to a mean of 9.2 (SD 17) (P < 0.0001). The final result was satisfactory for 88% of the patients.
Conclusions
The early results show intraosseous fixation to be a safe and efficient method for the fusion of the first TMT joint providing good patient satisfaction.
