Scapholunate Kinematics After Combined Palmar and Dorsal Ligament Reconstruction: A Quantitative Evaluation Using Four-Dimensional Computed Tomography.
J Hand Surg Am
January 2025
Department of Plastic, Reconstructive and Hand Surgery, Amsterdam University Medical Center location University of Amsterdam, Amsterdam, The Netherlands.
Purpose: This observational pilot study investigated (1) carpal positioning in the neutral wrist pose, (2) the scapholunate (SL) rotation axis, (3) physiological SL motion, and (4) the SL distance after combined palmar and dorsal SL ligament reconstruction using quantitative four-dimensional computed tomography (4D-CT) imaging.
Methods: Six subjects were included, and 4D-CT images of both wrists were obtained. Kinematic parameters of the treated side were compared to those of the healthy contralateral side, which was used as the normal reference.
Introduction: wrist ligament injuries and triangular fibrocartilage complex (TFCC) lesions are common but often underdiagnosed conditions causing chronic wrist pain. The diagnostic challenge necessitates a combination of clinical examination, imaging studies, and arthroscopy, considered the gold standard. Ligament injuries, particularly scapholunate ligament (SL), and TFCC lesions account for significant wrist instability and ulnar-sided wrist pain, respectively.

Articular malalignment and ulnocarpal impaction can progress to osteoarthritis in the wrist. This may be triggered by tears of the scapholunate ligament (rarely the lunotriquetral ligament) or the foveal lamina of the triangular fibrocartilage complex. In the pre-degenerative stages, radiographic findings are inconclusive, and symptoms may be absent or discrete.

Department of Hand, Plastic, Reconstructive and Burn Surgery, BG Unfallklinik Tuebingen, Eberhard Karls University Tuebingen, Tübingen, Germany.
Introduction: Perilunate dislocations (PLD) and perilunate fracture-dislocations (PLFD) are high-energy wrist injuries often linked to significant post-traumatic osteoarthritis. This study aims to determine whether PLD and PLFD yield different radiological outcomes following surgical treatment while identifying prognostic factors for worse outcomes.
Materials And Methods: We retrospectively analyzed 51 patients treated for perilunate injuries between 2000 and 2022.
Anatomic C Scapholunate Reconstruction Technique: For Complete Dissociation of the Scapholunate Interval.
J Hand Surg Glob Online
November 2024
Department of Orthopedic Surgery, Crystal Clinic, Akron, OH.
This surgical technique article describes the anatomic C scapholunate reconstruction technique. It is indicated for complete acute or chronic scapholunate ligament dissociation. The technique addresses severe scapholunate interval gapping, ulnar translocation of the lunate, and rotational/dorsal intercalated segment instability.
