We report the management of the acquired claw-toe deformity in ten adults. Each patient developed a varying number of claw toes at a mean interval of six months after the time of injury. There was clinical evidence of an acute compartment syndrome in one case. The clawing occurred at the start of heel-rise in the stance phase of gait. At this stage the patients complained of increasing pain and pressure on the tips of the toes. The deformities were corrected by lengthening flexor hallucis longus and flexor digitorum longus alone or in combination. The presence of variable intertendinous digitations between the tendons of flexor hallucis longus and flexor digitorum longus means that in some cases release of flexor hallucis longus alone may correct clawing of lesser toes.
The purpose of our study was to determine whether restricted excursion of the PQ muscle alone could affect forearm rotation.
Materials and Methods
Specimen PreparationEight adult, fresh-frozen, unmatched upper extremities were amputated at the mid-humerus. All of the specimens used appeared free from any prior trauma. The skin, subcutaneous tissue, and forearm flexor and extensor muscles were excised to the level of the wrist joint. The biceps tendon, elbow

AbstractBackground Loss of forearm rotation is frequently seen after healing of distal radius fractures. Questions/Purposes Our purpose was to determine whether restricted excursion of the pronator quadratus muscle can affect forearm rotation. Methods We evaluated the relationship between pronator quadratus excursion and forearm rotation in a cadaveric model. Eight adult fresh-frozen above-elbow specimens were attached to a mounting device that permitted free rotation of the forearm around its ulnar axis. Forearm rotation was measured with a protractor while alternating pronation and supination loads were applied. Measurements were repeated after restricting the excursion of pronator quadratus by 10, 20, and 30% of its initial length. Results There was a mean 15°loss of supination for each 10% reduction in pronator excursion. There was no significant effect on pronation. Conclusions We conclude that, independent of any bone deformity or nearby joint stiffness, posttraumatic scarring of this muscle may result in a loss of supination.
A case of accessory talus is described in which a large ossicle on the medial aspect of the talus had formed an articulation with the distal tibial epiphysis and had produced a fixed equinus deformity of the ankle. We propose that this ossicle, in association with a previously excised accessory toe at the level of the base of the first metatarsal, represents a partial duplication of the medial column of the foot.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
