Bilateral simultaneous mallet finger: An unusual case

Öz

Çekiç parmak, distal falanks bazisindeki ekstansör mekanizmanın aşırı ve ani şekilde fleksiyona zorlanması sonucu oluşan bir deformitedir. Akut dönemde distal interfalangeal eklemi hiperekstansiyonda tutan splintler ile konservatif olarak başarılı bir şekilde tedavi edilebilir. Ancak distal falanksta volar subluksasyon olanlarda, geçikmiş vakalarda ve distal interfalangeal ekleminin 1/3\'ünden fazlasını içeren avulsiyon kırığı olanlarda cerrahi müdahele gerekmektedir. Bu yazıda, travmanın üzerinden 2 hafta geçtikten sonra, her iki el 4. parmakta çekiç parmak deformitesi nedeniyle kapalı redüksiyon ve ekstansiyon blok yöntemi ile tedavi edilen 35 yaşında bayan hasta sunulmuştur. Ameliyattan sonra altıncı haftada pinler tahliye edilmiş ve üçüncü ay kontrolünde eklem hareketleri tam olarak değerlendirilmiştir. Akut dönemde konservatif tedavi tercih edilse de, eklem yüzeyinin 1/3\'ünden fazlasını içeren kopma kırığı olan ve geçikmiş vakalarda cerrahi tedavi önerilmektedir

Bilateral simultaneous mallet finger: An unusual case

Öz

Mallet finger is a deformity that a result of sudden and extreme forced flexion on extensor mechanism at the base of distal phalanx. In acute stage, it can be treated successfully by immobilization of distal interphalangeal joint with hyperextension splints. However, if there is volar subluxation of distal phalanx or fracture including more than 1/3 of articular surface of distal interphalangeal joint and in delayed cases, surgery is indicated. In this paper, 35 year old female patient who was treated by closed reduction and extension block technique in two weeks after the trauma because of the mallet finger deformity of 4th fingers of both hands is presented. Pins were removed after 6 weeks of the operation and range of motion of distal interphalangel joint was evaluated as full on the three months follow-up. Although conservative treatment is the choice for acute phase of trauma, we recommend surgical treatment in delayed cases and in the injuries involving the fractures more than 1/3 of articular surface.
