Article Abstract
Background: Hand injuries pose challenges due to complexity and aesthetic-functional concerns. Dorsum of hand injuries are difficult to treat due to thin skin cover and increased propensity to exposure of underlying structures. Perforator-based flaps can provide better outcomes with minimal donor site morbidity. This study aims to bridge the gap in anatomical knowledge and explore the potential benefits of dorsal carpal artery perforator flap.
Materials And Methods: A prospective study was done from July 2021 to June 2023, focused on study of dorsal carpal artery perforators on 12 fresh frozen cadaveric hands. Anatomical study involved injection of red latex into arteries at the wrist, followed by dissection and measurements. During the clinical phase, we used the inferences gained from the anatomical study to identify and mark perforator of dorsal carpal arteries. We performed V-Y advancement flap based on the DCPs in 5 patients who had dorsum of hand defects due to trauma.
Results: The study was carried out on 6 fresh frozen cadavers (12 hands). Anatomical findings revealed the anatomical location, caliber, and consistent number of dorsal carpal artery perforators supplying the dorsum of the hand arranged in 2 rows. Clinically, we applied this insight to create V-Y flaps in 5 patients with successful outcomes, thus, offering DCP-based flap as an alternative to distant flaps.
Conclusion: DCP-based flaps offer an efficient solution for reconstructing proximal hand defects over the dorsum, with minimal complications, enhancing our understanding of hand reconstruction options. The study's comprehensive anatomical insights and clinical outcomes contribute to improving hand defect management and surgical techniques.

Introduction: This study aimed to explore the effect of displaced dorsal rim fragments under defined size threshold on the clinical outcome.
Materials And Methods: Forty patients with an acute distal radius fracture accompanied by a dorsal rim fragment comprising less than 10% of the radiocarpal articular surface were included in the study. The size of the dorsal rim fragment was measured by axial CT scans and three-dimensional (3D) CT scans, and the correlation between these two methods was analyzed to evaluate the reliability of axial CT scan measurements.

J Hand Surg Am
December 2024
Division of Hand and Upper Extremity Surgery, Department of Orthopaedic Surgery, Emory University, Atlanta, GA. Electronic address:
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.

Department of Surgery, Section of Plastic Surgery, Michigan Medicine.
Background: Scapholunate (SL) and lunotriquetral (LT) ligament injuries are frequently undiagnosed and can lead to progressive loss of wrist function and chronic pain. Many surgical reconstruction options exist, but outcomes are suboptimal and no superior approach has been established.
Methods: Consecutive candidates for SL and/or LT ligament reconstruction utilizing an all-dorsal augmented intercarpal ligament reconstruction (ADAIR) were evaluated in this prospective case series.
Ulnar Head Fracture with Volar Dislocation of the Distal Radioulnar Joint: A Case Series and Systematic Review.
J Wrist Surg
December 2024
Department of Trauma and Orthopaedics, Liverpool University Hospitals NHS Foundation Trusts, Liverpool, United Kingdom.
Dislocations of the distal radioulnar joint associated with a fracture of the distal ulna articular surface without an associated radial fracture are extremely rare. We present a case of a fracture of the distal ulna with an associated dislocation of the distal radioulnar joint, where the articular head fragment was displaced anterior to the sigmoid notch. We also present the results of a formal systematic review of these injuries which confirmed this is the first such injury described, although there is a very similar fracture pattern described in the literature with dorsal dislocation.
