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.

Background: Mallet finger injuries, characterized by a flexion deformity caused by trauma to the extensor mechanism at the base of the distal phalanx, can lead to significant functional impairment if not treated appropriately. Surgical interventions for osseous mallet finger injuries often include techniques such as extension-block pinning and perioperative modifying plate fixation. When comparing these two methods, it is critical to assess factors such as technical ease, perioperative considerations, and postoperative outcomes.

Purpose: Terminal extensor tenotomy or Dolphin tenotomy, is a described treatment for the management of distal interphalangeal (DIP) joint hyperextension in chronic boutonniere deformity. The purpose of this study was to investigate the effects of incremental partial Dolphin tenotomy in correcting boutonniere deformity, with a focus on evaluating the improvement in DIP joint hyperextension deformity and documenting the development of iatrogenic mallet finger.
Methods: Thirty-eight fingers from 10 cadaveric hands were used.

Article Synopsis
- The study compares outcomes between two types of finger injuries—bony and tendinous mallet fingers—treated with splints in children, focusing on extensor lag at the distal interphalangeal joint.
- Data was collected retrospectively from 31 pediatric patients, indicating that bony mallet injuries more commonly affect the middle finger and tendinous mallets affect the ring finger, with both injuries being more prevalent in males.
- Despite differences in demographic details, both types of mallet finger injuries showed excellent recovery outcomes, with no significant difference in extension lag or overall assessment scores.

Background: Deficient shoulder function is a common and exhausting issue in children with obstetric brachial plexus injuries. Even with functioning elbow, wrist, and fingers, upper limb function is markedly disabled by limited shoulder abduction external rotation. Lower trapezius transfer carries many advantages; simple and safe technique, same line of pull as donor; reliable nerve supply (extraplexal from spinal accessory nerve), and not acting on rotation of the shoulder, mostly it will not adversely affect internal rotation range after the transfer.
