Current Concepts in the Evaluation and Treatment of Mallet Finger Injury

Abstract

The mallet finger is a frequently encountered fingertip injury that leads to extensor lag of the distal phalanx. Classification systems stratify these injuries as ranging from soft-tissue disruption of the extensor mechanism alone to those that have articular involvement and volar subluxation. The management of mallet finger injuries varies based on injury pattern and surgeon preference. These treatment options include splinting regimens, closed reduction and percutaneous pinning, and open reduction and internal fixation. Although the final goal of treatment is to establish a congruent joint, the efficacy of each treatment modality has been shown to vary.

Simultaneous Bony Mallet Fingers of Two Phalanx in a Patient: A Rarely Seen Case Report

“…Mallet finger is one of avulsion injuries and a common fingertip injury with a prevalence of 1:10,000 (Bloom et al, 2013). The dominant hand middle, ring, and little fingers are most often affected (Bloom et al, 2013).…”

“…Mallet finger is a common fingertip injury with a prevalence of 1:10,000 that involves disruption of the extensor mechanism at its terminal insertion, resulting in inability to actively extend the distal interphalangeal joint (Bloom et al, 2013). The injury is most commonly sustained during sporting activity activity especially associated with ball use (Er et al, 2014).…”

“…The injury is most commonly sustained during sporting activity activity especially associated with ball use (Er et al, 2014). The dominant hand middle, ring, and little fingers are most often affected (Bloom et al, 2013). If the mallet deformity is not treated appropriately it can lead to permanent deformities like flexion deformity and inability to actively extend the distal interphalangeal (DIP) joint and swan neck deformity (Kanaya et al, 2013).…”

“…Surgery is reserved in delayed cases and if there is a fracture including more than one third of articular surface of distal interphalangeal joint, distal phalanx volar subluxation, conservative management failure, avulsed fragment that fails CASE REPORT reduction, and absence of full passive extension of the joint (Anderson, 2011). In the literature there are great sum of studies including mallet finger deformities as simultaneous, bilateral or multiple variations and treatment strategies (Bloom et al, 2013;Er et al, 2013;Kanaya et al, 2013;Miranda et al, 2015). But simultaneous bony mallet fingers deformity is not reported.…”

SURGICAL MANAGEMENT OF DISTAL PHALANGEAL INJURIES OF FINGERS (review)

“…Первый этап проводится с применением мультисенсорного подхода сразу после травмы или реконструкции, чтобы свести к минимуму потерю соответст-вующей кортикальной зоны в коре головного мозга [43]. Предложены разные схемы и мето-дики, включающие также метод с применением зеркала -перевоспитание чувствительных цен-тров коры мозга с помощью зеркального эффек-та [25,114]. Второй этап чувствительного пере-воспитания начинают, когда в пораженном уча-стке ДФП воспринимается осязание.…”
