An interventional study of surgical fixation of acute bony mallet finger in Acute Bony Mallet Finger, sponsored by Sohag University. Recruiting at 1 site in Egypt. Per ClinicalTrials.gov, last updated 2024-05-03.
Sponsored by Sohag University · Not applicable, Interventional, and Treatment
Mallet finger is an avulsion fracture of the distal phalanx or rupture of the extensor terminal band caused by distal interphalangeal (DIP) joint hyperflexion or axial loading. In the treatment of mallet finger fractures, surgical repair is recommended in cases where the fracture involves more than one-third of the distal phalanx joint surface or the distal phalanx becomes volar subluxated
The blocking k.wire and micro plate technique are some of the methods used in the treatment of mallet finger fractures In recent years, the blocking k.wire technique has gained popularity owing to its minimally invasive nature and its ability to achieve satisfactory postoperative results
The main advantages of Micro Plate technique include provision of anatomical reduction and stable fixation, avoiding the risk of fragmentation of the small dorsal fragment, allowing early movement and increasing patient comfort and compliance

Exclusion Criteria:
1- . crushed distal phalanx 2. soft tissue mallet 3. multiple phalangeal fractures 4. old neglected cases
Group A : acute bony mallet finger managed by micro plate fixation
Procedure: surgical fixation of acute bony mallet finger
Group B : Acute bony mallet finger managed by blocking k.wire fixation
Procedure: surgical fixation of acute bony mallet finger
surgical fixation of acute bony mallet finger by micro plate will be performed under either Infraclavicular nerve blockage or digital block will be performed in all patients .fracture fragment will be reduced, The legs of the plate will be embedded in the terminal tendon to grasp the fragment. The plate will be fixed to the distal phalanx with a 1.3-mm screw. surgical fixation of acute bony mallet finger by blocking K.wire will be performed under either infraclavicular nerve block or digital block. The injury will be surgically intervened with an extensor blocking k.wire. the distal phalanx was extended to maximum flexion and (K.wire) will be placed in the cephalic direction through the terminal band at an angle of 45 degrees to the mid-phalanx. Reduction of the fracture fragment will be achieved by bringing the distal phalanx to extension . the DIP will be transfixed with a second K-wire
