Zusammenfassung
Hintergrund
Die Therapie von Radiusköpfchenfrakturen des Typs Mason II wird nach wie vor kontrovers diskutiert. Wir stellen die Technik der perkutanen Reposition ohne additive Stabilisierung als Alternative zur offenen Reposition mit zusätzlicher Osteosynthese vor und präsentieren die Ergebnisse der Methode.
Material und Methode
Die Daten von 26 von 30 Patienten, welche konsekutiv bei einer Fraktur des Typs Mason II versorgt worden waren, wurden retrospektiv evaluiert. In die Analyse flossen der „Disabilities of Shoulder and Hand Score“ (DASH-Score), der „Mayo Elbow Performance Score“ (MEPS) sowie die radiologische Untersuchung ein.
Ergebnisse
Das Follow-up betrug 21 (6–47) Monate. In 22 Fällen (85%) konnte ein anatomisches Repositionsergebnis erzielt werden. Zwei Fälle (8%) zeigten einen vollständigen, 2 Fälle (8%) einen geringen Repositionsverlust. Der DASH-Score lag bei 5,6 (0–56) Punkten, der mittlere MEPS betrug 93,8 (60–100, SD). Lediglich 4 Patienten (15%) äußerten eine persistierende, subjektive Funktionseinschränkung im Sinne eines DASH-Wertes > 10.
Schlussfolgerung
Die Ergebnisse belegen die Anwendbarkeit dieses minimal-invasiven Verfahrens zur operativen Versorgung von Radiusköpfchenfrakturen Typ Mason II. Die Methode stellt damit eine sehr gute Alternative zur offenen Reposition dar.
Abstract
Background
The therapeutic algorithm for the treatment of Mason type II radial head fractures is still controversially discussed. This study describes the technique of percutaneous fracture reduction without additional internal fixation of the radial head as an alternative to open reduction and presents the results of the method.
Material and methods
The data from 26 out of 30 patients with a Mason type II radial head fracture who had been consecutively treated with percutaneous fracture reduction were evaluated retrospectively. The analysis comprised the disabilities of shoulder and hand (DASH) score, the Mayo elbow performance score (MEPS) and data from the radiological examinations.
Results
The average follow-up time was 21 months (range 6-47 months). In 22 cases (85 %) an anatomical reduction could be achieved, 2 cases (8 %) showed a complete redislocation of the fragment and 2 cases (8 %) a partial redislocation. The average DASH score was 5.6 points (range 0–56) and the average MEPS was 93.8 (range 60–100). Only 4 patients (15 %) reported persisting functional impairment with a DASH score >10.
Conclusions
The method of percutaneous reduction of radial head fractures without additional internal fixation in Mason type II fractures has been demonstrated to be a good alternative to open reduction.
