Zusammenfassung
Geschlossene Streckhaubenverletzungen am Grundgelenk der Langfinger gehören zu den seltenen Verletzungen. In unserem Krankengut fanden sich in den vergangenen zehn Jahren sechs Patienten mit einer derartigen Verletzung, die operativ versorgt wurden. In fünf Fällen war der dorsoradiale, in einem Fall der dorsoulnare Anteil der Streckerhaube betroffen. Der Riß verläuft längs oder schräg durch die transvers angeordneten Fasern der Streckerhaube. Hinsichtlich des Unfallmechanismus werden direkte tangentiale Krafteinwirkungen auf die Streckerhaube sowie forcierte Ulnarabduktion im gebeugten Grundgelenk der Langfinger beschrieben. Die Diagnose wird regelhaft durch die ruckartige Luxation der Strecksehne nach der Ulnarseite bei zunehmender Beugung im Grundgelenk gestellt, gelegentlich tritt eine Ulnarabweichung des Fingers auf. Fehldiagnosen der uns überwiesenen Fälle lauteten: „schnellender Finger“ und „rezidivierende Grundgelenkluxation“; einmal hieß die präoperative Diagnose wegen fixierter Luxation „Strecksehnenriß“, da ein permanentes Streckdefizit von 30° bestehen blieb. Die Therapie ist immer operativ mit Naht und vierwöchiger Ruhigstellung des Grundgelenks in Streckstellung, da eine konservative Behandlung den Riß nicht zur Ausheilung bringen kann.
Abstract
Closed traumatic lesions of the extensor tendon hood of a longfinger at the metacarpophalangeal joint are rare. Surgical treatment was done in 6 cases during the last 10 years in our department; in 5 cases the dorsoradial part, in one case the dorsoulnar part of the hood was injured. The tear extended longitudinal or diagonal through the transvers fibers of the hood. Respecting the accident mechanism there have been reported tangential forces at the extensor tendon hood and forced ulnar deviation in the bended metacarpophalangeal joint. A jerky dislocation of the extensor tendon to the ulnar side of the metacarpophalangeal head during increased bending of the metacarpophalangeal joint, sometimes with ulnar abduction of the longfinger, leads usually to the diagnosis. Misdiagnoses of cases sent to our department were: „trigger finger“ and „recurrent dislocation of the metacarpophalangeal joint“. Once the presurgical diagnosis was „rupture of the extensor tendon“ because of a permanent extension deficit in 30 degree position of the metacarpophalangeal joint. Treatment is always surgical with suture of the hood and immobilization of the metacarpophalangeal joint in extension position for 4 weeks. Conservative treatment can not heal up a tear of the extensor tendon hood.
