Zusammenfassung
Hintergrund
Ziel der Studie war es, bei der arthroskopischen Stabilisierung der akuten akromioklavikulären (AC-)Gelenkluxation die Verwendung von einem Single-TightRope™ (STR) vs. zwei Double-TightRope™- (DTR-)Implantaten zu vergleichen, mit der Hypothese, dass DTR eine geringere korakoklavikulären (CC-)Distanz erzielt.
Patienten und Methoden
Es wurden 29 konsekutive mit TR operierte Patienten (d = 38,1 Jahre; n = 26 männlich) im Rahmen einer Kohortenstudie mit einem Follow-up von 13,3 (12,0–21,7) Monaten nachuntersucht. Eingeschlossen wurden die akute AC-Gelenksprengung Typ III und V nach Rockwood®. Es erfolgte eine Auswertung der prospektiv präoperativ, 3, 6 und 12 Monate postoperativ erhobenen Scores und Röntgenbildgebung.
Ergebnisse
Eine Rockwood- (R-)III-Verletzung erlitten 12 Patienten, 17 eine R-V-Verletzung; 14 wurden mit STR stabilisiert, 15 mit DTR. Mit STR wurden 8 R-III- und 6 R-V-Verletzungen, mit DTR 4 R-III- und 11 R-V-Verletzungen adressiert. STR erzielte in 5 Fällen (36%) eine CC-Distanz von > 125% im Vergleich zur gesunden Gegenseite, wovon 2 eine R-V- und 3 eine R-III-Verletzung darstellten. Mit DTR lag die CC-Distanz in 2 Fällen (13%) einer R-V-Verletzung >125%.
Schlussfolgerung
Die DTR-Technik erzielte eine geringere CC-Distanz ohne signifikanten Unterschied der gemittelten CC-Distanz und der Scores in der Jahreskontrolle.
Abstract
Background
The aim of this study was to compare the results of the single (STR) versus double TightRope™ (DTR) technique for stabilisation of acute separations of the AC joint with the hypothesis that DTR achieves lower CC distance.
Patients and methods
A total of 29 consecutive patients treated operatively with the TR technique (mean age 38.1 years, n=26 male) were analysed in a cohort study with a mean follow-up of 13.3 months (12.0–21.7). Acute AC joint separations types III and V according to Rockwood (R) were included; R types I, II, IV and VI were excluded. The prospective scores determined pre-op and 3, 6 and 12 months post-op and X-rays were evaluated.
Results
Of the patients 12 suffered an R type III and 17 an R V separation; 14 were treated with STR and 15 with DTR. With STR, 8 R III and 6 R V injuries and with DTR 4 R III and 11 R V injuries were treated arthroscopically. STR achieved an increased CC distance >125% compared to the contralateral AC joint in five cases (36%). Two of them occurred as R V and three as R III injury. DTR achieved a CC distance >125% in two cases of an R V injury (13%).
Conclusion
The DTR technique provides lower CC distance compared to the STR technique, without a significant difference of CC distance and scores.
