Patient-specific scaphoid prosthesis: surgical technique.

The scaphoid bone is essential for wrist stability, force transmission, and movement, being crucial for maintaining carpal kinematics. In cases where the scaphoid is non-reconstructable, a complete replacement can serve as a treatment option to preserve carpal alignment and motion. This approach has evolved since its first descriptions in 1945, benefiting significantly from advancements in patient-specific implant design, additive manufacturing/3D printing, and material use in recent years.

Front-to-Back Arthroscopic Repair of Complete Lunotriquetral Ligament Injuries: A Case Presentation and Algorithm for Arthroscopic Management of Intercarpal Ligament Injuries.

The lunotriquetral intercarpal ligament (LTIL) is an important structure that equalizes the forces on the lunate imparted through the scapholunate intercarpal ligament. The extension moment of the triquetrum balances the flexion force of the scaphoid, positioning the lunate for efficient load transfer from the hand to the wrist. In contrast to the scapholunate intercarpal ligament, the LTIL is strongest volarly, with the most critical region being associated with the volar ulnocapitate ligament.

Treatment Options, Return to Play, and Functional Performance after Operatively and Non-operatively Managed Acute Scaphoid Fractures.

Purpose Of Review: Scaphoid fractures are commonly encountered injuries in the athletic population. Conservative management is pursued for incomplete fractures and those involving the distal pole. Operative management is indicated for displaced fractures, unstable fractures, and those involving the proximal pole.

An endpoint adjudication committee for the assessment of computed tomography scans in fracture healing.

Introduction: Endpoint Adjudication Committees (EACs) benefit the quality of randomized control trials (RCTs) where outcomes depend on subjective interpretations. However, assembling a committee to adjudicate large datasets is cumbersome. In a recent RCT, the primary outcome was time to union following operative fixation of scaphoid non-union, with real or placebo adjunctive ultrasound treatment.

The subtle scaphoid fracture in childhood: A case report with literature insights.

We describe a 9-year-old male who suffered a linear, non-displaced scaphoid fracture following a pedestrian motor vehicle accident. Initially, X-ray imaging failed to detect the fracture, but MRI confirmed the diagnosis, highlighting the challenges in identifying scaphoid fractures in pediatric patients due to the bone's cartilaginous nature in this age group. The patient was treated with immobilization using a Plaster of Paris cast, consistent with standard management for non-displaced fractures in children.

Update on Management of Scaphoid Fractures.

Learning Objectives: After studying this article, the participant should be able to: 1. Accurately diagnose scaphoid fractures through examination and appropriate imaging selection. 2.

Surgical repair of posttraumatic injuries of the scapholunate ligament: A literature study.

Background And Research Aims: Scapholunate interosseous ligament rupture can cause wrist issues like pain, strength loss, and cartilage degeneration. While various surgical treatments exist, it's unclear which method is optimal. This study aims to determine the superior treatment approach for scapholunate dissociation.

Management of Scaphoid Nonunion With Iliac Crest Graft and K-wire Fixation: An Economically Viable Option.

Purpose This study details the functional results, patient satisfaction, and cost-effectiveness of patients treated with Fisk-Fernandez surgery using iliac crest graft and K-wire for scaphoid nonunion. Materials and methods This study involved a retrospective analysis conducted between November 2022 and August 2024. Forty-two patients diagnosed with scaphoid nonunion were treated using a surgical approach that included autologous bone grafting combined with K-wire fixation to promote bone healing and stability.

Volar locking and angular stability plate for treatment of comminuted scaphoid fractures: a case series of 44 cases.

Background: The primary method employed worldwide for the treatment of scaphoid fractures is screw fixation. However, in unstable and comminuted fractures, percutaneous fixation could produce complications due to technical challenges, such as improper axis positioning, inaccurate screw length measurement, intra-articular screw penetration, and impingement. Alternative open approaches for the surgical management of scaphoid fractures have been proposed, and in recent years, a new specific volar locking plate for the treatment of scaphoid fractures has been developed.

A Subunit-Based Concept for Preoperative Design of the Cauliflower Ear.

Purpose: Cauliflower ear is an ear deformity caused by a closed ear injury with varying severity. Several studies on the systematic reconstruction of cauliflower ear have been reported. Here, the authors aim to introduce a simplified subunit-based reconstruction concept for the cauliflower ear.

Editorial Commentary: Olecranon Bone Autografting Combined With an Arthroscopic Approach for the Treatment Scaphoid Nonunion-An Important Technique for Wrist Surgeons.

Effective treatment of scaphoid pseudoarthrosis is critical to reduce the risk of progression to the potentially debilitating scaphoid nonunion advanced collapse, including complications of persistent wrist joint instability, degenerative arthritis, decreased range of motion, chronic pain, and functional impairment. Both anatomic and fracture-related pathophysiology predispose patients to scaphoid nonunion, including limited retrograde blood flow, fracture location, and delay of appropriate treatment. Recent studies have demonstrated successful outcomes in treatment of scaphoid nonunions, with nonvascularized bone autograft, commonly from distal radius or iliac crest, as well as pedicled vascularized or free vascularized autograft with rates of union varying from 84% to 100%.

Vascularized hemi-hamate graft: Anatomic description of a novel pedicled osteo-chondro-ligamentous flap for proximal scaphoid reconstruction.

Scaphoid proximal pole destruction remains a surgical challenge owing to its high propensity for nonunion and osteonecrosis. The hemi-hamate graft has shown promising results in addressing this issue. However, long-term results of non-vascularized composite grafts remain uncertain.
