Rationale: Thumb function is one of the most fundamental components of hand function, and a vast majority of hand functions are derived from thumb motion. Injury of the thumb interphalangeal joint has a tremendous impact on the function of the thumb, and damage to the thumb interphalangeal joint (IPJ) caused by trauma is usually accompanied by dislocation of the surrounding skin; therefore, it is particularly important to restore the thumb anatomy and skin coverage.
Patient Concerns: A 41-year-old woman presented with IPJ disfigurement accompanied by a local skin defect caused by machine compression of her right thumb. Restoring the appearance and function of the thumb is key to this operation.
Diagnoses: Open fracture of the right thumb.
Interventions: After detailed preoperative and radiographic evaluation, the appearance and function of the thumb were reconstructed by IPJ grafting and artificial dermis covering.
Outcomes: At 4 months' follow-up, the patient's visual analogue score was 0, no complications (eg, osteomyelitis, osteolysis, osteoarthritis, and nonunion of the artificial dermis) were observed, and the range of motion of the thumb IPJ returned to 60% of that of the healthy side.
Lessons: The innovative application of the second toe proximal IPJ flap combined with double-layer artificial dermis covering to reconstruct the thumb IPJ defect not only solves the problem of skin defects in the recipient area after transplantation in previous cases but also restores the beauty of the recipient area, making it easier for patients to accept this surgical program.

Surgical excision of symptomatic lateral band snapping syndrome in small finger proximal interphalangeal joint.
BMJ Case Rep
January 2025
Orthopedic Surgery, OhioHealth, Columbus, Ohio, USA.
Lateral band snapping syndrome can be a debilitating condition involving the proximal interphalangeal (PIP) joint of the fingers. Although rare, it is thought to occur due to disruption of the finger extensor mechanism allowing inappropriate subluxation of the lateral bands over the PIP joint, leading to mechanical and painful symptoms.Here, we describe a woman in her early 40s with a painful, snapping PIP joint secondary to a work-related injury.

We propose a novel US score to quantify the cortical-entheseal bone remodeling burden of several peripheral entheses, aiming to improve the specificity of US for PsA-related enthesitis, and to evaluate its diagnostic value in PsO patients with subsequent diagnosis of psoriatic arthritis (PsO/PsA).
Methods: clinical and US data of 119 consecutive patients with moderate/severe PsO and nonspecific musculoskeletal symptoms, were included in this retrospective study.
A Novel Technique With Buttress Plating for Comminuted Base Fractures of the Proximal Phalanx.
Ann Plast Surg
December 2024
Department of Orthopaedic Surgery, Duson Hospital, Ansan, Korea.
Background: Extra-articular but severely comminuted distal basal fractures of the proximal phalanx (PP) are rarely reported. Therefore, the aim of this study was to achieve proper union and desirable outcomes using low-profile locking plates/screws. We introduced our own surgical approach and reported the clinical/radiographic outcomes via retrospective case series.

Orthopedic Department, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.
Background: Adhesion formation poses a significant challenge for both patients and hand surgeons following tendon repair. One common strategy to prevent adhesion formation is the use of physical barriers. This study aimed to compare the outcomes of extensor tendon repair with and without the application of the OrthoWrap bioresorbable Sheet, specifically in terms of adhesion prevention.

Indian J Plast Surg

While proximal phalangeal joint injuries with comminution of the base of the middle phalanx are common injuries, proximal interphalangeal (PIP) joint fracture dislocations with an intact base of middle phalanx and a comminuted head of proximal phalanx are rare. Volar plate arthroplasty and other described techniques prevail for the former injury, while the latter does not have any supportive literature on the exact method of management. We herein present a 20-year-old male with a severely comminuted head of proximal phalanx fracture with dislocation of the PIP joint, which was not reconstructable but was managed successfully with a novel technique of volar plate draping that resurfaced the raw phalangeal head.
