To test a new generation of compression screws: the Acumed Acutrak 2 Mini (AA; Acumed, Hillsboro, OR), the Stryker TwinFix (ST; Stryker, Kalamazoo, MI), and the Synthes 3.0 headless compression screw (SH; Synthes, Solothurn, Switzerland). ⋯ A new generation of headless compression screws, by producing higher compression forces, increase stability at the fracture site and might thereby promote bone healing.

We report the case of a large intraneural neurothekeoma of the median nerve at the wrist. Neurothekeomas are rare; they are small, superficial, and typically asymptomatic benign tumors of undetermined cellular origin. Complete excision is usually curative. This case is interesting owing to the tumor's large size and location within the median nerve, which made it highly symptomatic, mimicking carpal tunnel syndrome.

Ulnar nerve dysfunction is a common sequela of surgical treatment of distal humerus fractures. This study addresses the null hypothesis that different types of distal humerus injuries have comparable rates of diagnosis of ulnar neuropathy. ⋯ Prognostic IV.

Proximal row carpectomy and 4-corner arthrodesis are 2 well-established motion-preserving treatment strategies for scapholunate advanced collapse. In this study, we present an arthrodesis technique involving the capitolunate and triquetrohamate joints as another potential treatment option. ⋯ Therapeutic IV.
