Zusammenfassung
Hintergrund
Ziel dieser Studie war, die Evaluation der klinischen und radiologischen Ergebnisse von 37 Patienten (Durchschnittsalter 37,9 Jahre; weiblich 4, männlich 33 Patienten) mit akuten AC-Gelenksprengung Typ V nach Rockwood nach arthroskopisch assistierter und bildwandlerkontrollierter AC-Gelenkstabilisierung in Doppel-TightRope™-Technik.
Material und Methode
Nach 12 Monaten konnten 30 Patienten [Durchschnittsalter 38,8 (18,6–65,8)] Jahre anhand des „Subjective Shoulder Value“ (SSV), Constant-Scores (CS) und Taft-Score (TF) sowie radiologische mit Panorama- und Alexander-Stressaufnahmen nachuntersucht werden.
Ergebnisse
Im SSV wurden durchschnittlich 91,4±9,8% im CS 87,8±5,2 und im TF 10,1±2,1 Punkte erreicht. Präoperativ betrug der durchschnittliche korakoklavikuläre Abstand (CCA) 22,1±5,6 mm auf der betroffenen Seite und konnte 3 Wochen postoperativ signifikant auf einen CCA von 8,6±2,8 mm reduziert werden (p<0,05). Ein Jahr postoperativ zeigte sich ein mittlerer CCA von 12,9±2,4 mm. Die Differenz des CCA zur Gegenseite betrug initial 13,7±4,8 mm, postoperativ 0,3±3,0 mm und nach 12 Monaten 3,6±3,5 mm. Eine horizontale Instabilität wurde in 53,3% der Patienten beobachtet. Hier bestand eine Korrelation mit dem schlechteren funktionellen Ergebnis. Lediglich ein Patient wies nach 12 Monaten einen diskreten Druckschmerz im Bereich des AC-Gelenks auf.
Schlussfolgerung
Nach arthroskopisch assistierter AC-Gelenkstabilisierung in Doppel-TightRope™-Technik können trotz nachgewiesener partieller Rezidivinstabilität gute bis sehr gute klinische Resultate ein Jahr postoperativ erwartet werden.
Abstract
Background
The aim of this study was to evaluate the clinical and radiological results of 37 consecutive patients (Ø age 37.9; 4♀, 33♂) following arthroscopically assisted and image intensifier-controlled AC joint reconstruction using the double TightRope™ technique for acute AC joint separations grade V according to Rockwood.
Material and methods
After 12 months 30 patients with a mean age of 38.8 years (range 18.6–65.8 years) could be included. The postoperative assessment included the Subjective Shoulder Value (SSV), Constant Score (CS), and Taft Score (TF) as well as radiological evaluation using bilateral stress views and bilateral Alexander views for determining vertical and horizontal AC joint instability.
Results
The clinical scores reached 91.4±9.8% for SSV, 87.8±5.2 for CS, and 10.1±2.1 points for TF. The initial coracoclavicular distance (CCD) was 22.1±5.6 mm and could be reduced to 8.6±2.8 mm postoperatively (p<0.05). The CCD increased at final follow-up to 12.8±2.4 mm. The difference of the CCD compared to the contralateral side was initially 13.7±4.8 mm; postoperatively it was 0.3±3.0 mm with an increase at final follow-up to 3.6±3.5 mm. A posterior instability on the Alexander view occurred in 53.3% of patients. A correlation between inferior clinical results and horizontal instability could be detected. Only one patient was slightly tender to palpation at the AC joint.
Conclusion
Following arthroscopic AC joint stabilization using the double TightRope™ technique, despite partial recurrent instability, favorable clinical results can be expected.
