Distal Intersection Syndrome Between Second and Third Dorsal Compartments of the Wrist.

Distal intersection syndrome (DIS) is a rare form of tenosynovitis affecting the second and third dorsal extensor compartments of the wrist, which is rarer and more distal than the classically described intersection syndrome between the first and second compartments. In this report, we present three cases of DIS, their inciting activities, and ensuing treatment courses. Diagnosis of DIS was confirmed via MRI in all cases.

Revision of the Failed Thumb Carpometacarpal Arthroplasty.

Purpose: To evaluate the outcome of revision surgery for failed thumb carpometacarpal (CMC) arthroplasty.

Methods: We retrospectively analyzed 32 patients with failed thumb CMC arthroplasty. The primary reason for revision was pain caused by metacarpal subsidence.

Comparing Dorsal Tangential and Lateral Views of the Wrist for Detecting Dorsal Screw Penetration after Volar Plating of Distal Radius Fractures.

Background: The dorsal tangential (DT) view has been shown to improve the detection of dorsal screw perforation during volar distal radius fracture fixation. Here we performed a cadaveric imaging survey study to evaluate if the DT view was uniformly beneficial for all screws.

Methods: Standardized placement of fixed-angle volar distal radius plates was performed on two cadavers.
