Influence of First Metatarsophalangeal Joint Degenerative Changes on Functional Outcomes Following Hallux Valgus Correction

Hallux valgus and cartilage degeneration in the first metatarsophalangeal joint.

This study relates the extent of cartilage lesions within the first metatarsophalangeal joint to hallux valgus. We prospectively examined 265 first metatarsophalangeal joints of 196 patients with a mean age of 54.2 years at operation for the existence of cartilage lesions. Grade I lesions were found in 41 feet (15.5%), grade II in 82 (30.9%), grade III in 51 (19.3%), grade IV in 20 (7.5%). Only...

Cardan angle rotation sequence effects on first-metatarsophalangeal joint kinematics: implications for measuring hallux valgus deformity

BACKGROUND There currently are no recommended standards for reporting kinematics of the first-metatarsophalangeal joint. This study compared 2 different rotation sequences of Cardan angles, with implications for understanding the measurement of hallux valgus deformity. METHODS Thirty-one women (19 hallux valgus; 12 controls) participated. All were scanned in an open-upright magnetic resonance...

Pseudogout of the first metatarsophalangeal joint associated with hallux valgus: an atypical bilateral case.

Calcium pyrophosphate dihydrate crystal deposition disease has various clinical features, and pseudogout is one of the six clinical forms. Chondrocalcinosis is the term used to describe the radiographic appearance of the disease. A review of the literature revealed that the appearance of this type of arthropathy in the foot is infrequent. We offer a review of the disease and report an atypical ...

Arthroscopic Arthrodesis of the First Metatarsophalangeal Joint in Hallux Valgus Deformity

Arthrodesis of the first metatarsophalangeal joint is indicated for hallux valgus associated with degenerative changes, severe deformity, or rheumatoid arthritis and those for whom primary hallux valgus surgery has failed. Open approach requires extensive soft tissue dissection. The purpose of this Technical Note was to report the details of arthroscopic arthrodesis of the first metatarsophalan...
