Open reduction and K-wire fixation of mallet finger injuries: mid-term results

Abstract

An anatomical reduction is essential in mallet finger deformities. Open reduction and internal K-wire fixation can be preferred due to its low complication rate and ease of application in patients whose mallet deformity cannot be treated by closed reduction.

Principles of Hand Fracture Management

“…They found no statistically significant difference in functional outcome, but noted higher complication rates in those treated with open technique, although it did provide earlier mobilisation. The use of K wires is generally accepted to be more cost effective and reduces intra-operative time when compared to open reduction techniques, similar good results with K wire techniques have been shown in other studies [77, 78]. …”

Pull-Out Wire Fixation for Acute Mallet Finger Fractures With K-Wire Stabilization of the Distal Interphalangeal Joint

“…Many clinicians suggest that mallet finger fractures involving more than 30% of the joint surface should be treated surgically to obtain precise reduction and avoid osteoarthritis and joint stiffness. 17,18 Hofmeister et al 19 treated displaced mallet fractures with an extension block pin and transarticular fixation of the DIP joint, and obtained fracture union. However, the technique may result in extension lag of up to 20°.…”

Tratamento cirúrgico de fraturas em martelo por bloqueio da extensão com fio de Kirschner

“…Lin and Tseng 1 reported 41% of complication as nail deformities, superficial infection and pin track infection. With the open methods, Stark 17 reported 95% of successfull results and Orhun et al 9 reported 91%.…”

“…9 Thus, the fracture must be treated by surgical or conservative method. When the conservative treatment is applied, it is necessary to use an extension splint for six to eight weeks and then, use a night splint for one month.…”
