Carpal arch alteration after carpal tunnel release.

A retrospective clinical study quantitated postoperative widening of the transverse carpal arch after carpal tunnel release in a group of 50 patients. The relationship of this widening with postoperative pain, forearm circumference, grip strength, and wrist range of motion was evaluated. Mean widening of the transverse carpal arch after carpal tunnel release is 10.4% or 2.7 mm. A direct relationship exists between widening of the transverse carpal arch and loss of grip strength. Residual pain, forearm circumference, and wrist range of motion are not related to widening of the transverse carpal arch.

Biomechanical analysis of internal fixation techniques for proximal interphalangeal joint arthrodesis.

Although numerous fixation techniques have been developed for performing small joint arthrodesis, no previous study of the biomechanical properties of these constructs has been published. The strength of specimens of arthrodesis of the proximal interphalangeal joint performed with cadaver material was determined for three-point anteroposterior bending, axial torsion, and lateral cantilever bending stress. Crossed Kirschner wires, intraosseous wiring, and figure of eight tension-band wiring were studied. Figure of eight tension-band wiring demonstrates superior strength in anteroposterior bending and torsion. For lateral bending stress, no significant difference exists among the techniques studied.

Florid reactive periostitis.

A case of florid reactive periostitis of the thumb is reported. This rare, benign, bone-producing lesion is easily confused with osteosarcoma. It is also known as parosteal or nodular fascitis. Careful histologic and radiographic evaluations are needed to establish the diagnosis and avoid unnecessary amputation. Marginal excision seems to be adequate treatment.
