A postoperative heterotopic ossification leading to radial palsy.

We report the case of a 58-year-old man who developed radial palsy three months after surgical reinsertion of the distal biceps brachii through a single anterior approach. Radiographs and ultrasound examinations revealed heterotopic ossification compressing the deep branch of the radial nerve. Surgical excision and neurolysis were performed.

New radiographic monitoring indices for total trapeziometacarpal prostheses.

Objective: The objective of this study is to propose and evaluate a method of monitoring implants via the calculation of a trapezial and metacarpal index from radiological measurements and to describe an initial patient analysis.

Methods: This retrospective study describes the trapezial index which reflects the trapezial bone stock not occupied by the trapezial cup, while the metacarpal index reflects the rate of metacarpal occupation by the prosthetic stem. Those indexes were used on a series of 20 patients with a Maïa™ prosthesis with a minimum follow-up of seven years.
