Despite of its rarity, hamate hook nonunion can cause several complications like tendon rupture or loss of grip strength. Admitted treatments in the literature are excision of the bone fragment or its open reduction and internal fixation. We report a clinical case of a high-level baseball player with hamate hook nonunion treated with an original technique of fixation using a hook plate.

This study aimed to investigate the diagnostic and evaluative significance of combining median nerve (MN) morphological measurements with diffusion tensor imaging (DTI) and T2 mapping metrics for carpal tunnel syndrome (CTS). Morphological and multiparametric magnetic resonance neurography (MRN), along with clinical evaluation, were conducted on 33 CTS patients and 32 healthy controls. The MRN metrics included fractional anisotropy (FA), apparent diffusion coefficient (ADC), axial diffusivity (AD), radial diffusivity (RD), T2 value, cross-sectional area (CSA) and MN flattening ratio (MNFR) at both the pisiform bone and hamate bone levels.

Objectives: In this study, we present our extensive case series on hamatometacarpal fracture-dislocations treated with open reduction and internal fixation and share our treatment strategies and outcomes.
Patients And Methods: Between March 2014 and November 2022, a total of 17 male patients (mean age: 28.6±7.
Background: Understanding peripheral ulnar nerve anatomy is necessary to refine surgical treatment of ulnar nerve injuries. This study topographically mapped the ulnar nerve and its distal branch points from a well-defined surgical landmark and assessed for variations in interfascicular motor arrangement and branch size.
Methods: Fifty-four cadaveric upper extremities were dissected to expose the distal ulnar nerve and its branches (dorsal cutaneous (DCB), volar sensory (VSB), and motor branches).

Two high-level baseball players sustained a hook of hamate fracture while batting and were treated with excision of the fragment. Both players returned to play, and both had repeat fractures through a regenerated hook. This phenomenon of hook of hamate regeneration has not been well described in the literature.
