Measuring Visualized Joint Surface in Hallux Metatarsophalangeal Arthroscopy

Arthroscopy of the First Metatarsophalangeal Joint.

Arthroscopic treatments for the first metatarsophalangeal joint have not spread fully owing to a number of factors. First, in the common arthroscopic view, the joint is observed from above, which makes the structures difficult to grasp and the dorsal aspect of the joint difficult to visualize and treat. Second, techniques for widening the view have not yet been reported. Third, the portals nece...

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...

Hallux rigidus and osteoarthrosis of the first metatarsophalangeal joint.

Intramedullary and intra-osseous arthrodesis of the hallux metatarsophalangeal joint.

PURPOSE To review the outcome of arthrodesis of the hallux metatarsophalangeal (MTP) joint in 23 patients. METHODS Records of 9 men and 14 women aged 27 to 88 (mean, 57) years who underwent arthrodesis of the hallux MTP joint using an intramedullary device and an intra-osseous device were reviewed. Indications for surgery were severe hallux valgus (n=15), hallux rigidus (n=6) and rheumatoid a...
