Study Of Clinical Anatomy Of Palmaris Longus Tendon Autologous Transplantation For The Treatment Of Fresh And Closed Mallet Fingers

OBJECTIVE: Misshapen of mallet fingers is particularly common , As the course of diseases is never, For everyday lives of people have been inconvenienced. Although the domestic and foreign scholars to the operation method of study, The transplant tendons has made a brave attempt, But the effect of prognosis is not very good, Function is not very good return, Relapse rate is still very high. The reasons why there are two aspects A is not the proper operation of taking reasonable messerklinger B Is not fully grasp the fingers extensor tendon's the characteristics of the anatomy Transplant tendons to normal tendons of the larger In order to radically solve both problems The normal fingers through his fingers on tendons of cloth and tendons finger in every section of the length, width and thickness in the anatomical studies On the basis of our fingers around them; the length, width and thickness changes Appropriate choose to transplant tendons at length, width and thickness ,Then surgically messerklinger reform, Further the palmaris longus tendon autograft transplantation for the treatment of closed mallet fingers fresh clinical study , This method to explore the treatment of closed mallet fingers fresh feasibility .METHODS:1 To the regular adult formalin the specimen 80 side hand Men and women with a ten thirty back side of the line out tendons to observe, Use cursor callipers and ordinary micrometer each of the bone back to her fingers; The length width and thickness and a system of measurement Scientific experiment in the record of data and photograph, For data for Statistical analysis.2 To 12 fresh closed hammer of a people are pointed fingers; the length, width and thickness measurement to the transplant tendons to choose the length, width and thickness . Autologous transplant tendons to take a long line of treatment , DIP levels in the dorsal skin incision running, and for the extension of H-type incision. With an electric drill at the base of distal phalanx of bored run, will be removd through one of one of the tendons of-chip, after the film cross-tendon suture of the extensor tendon in the proximal. Of the extensor tendon to the proximal point mobile aboutr 1.5cm , flexor tendon to avoid the direct effect of stretch in the tendon stump Deprment. Direct suture with two re-constitute barriers ,strengthen the protection ends. RESULTS: In accordance with normal fingers; the form of the property to the right to choose the transplant tendons of tendons, autologous transplant tendons to take long for a fresh closed hammer to patients.Patients were followed up for3—4mouths inaccordance with the functional assessment Dargan:excellent 8cases,good in 2cases,2cases. Is an effective ingredient, Feature has been very good return.CONCLUSIONS: In accordance with normal fingers; the form of the property to the right to choose the transplant tendons of tendons, The use of autogenous palmaris longus tendon transplantion in the treatment of fresh closed mallet fingers is a feasible and effective ,a lower relapse rate method .Compared with the conservative treatment more precise,especilly for the restore function function and appearance of the patients have huigher requirements, the operation method is simple and practical ,easy to promote.
