Anatomical and functional study of the medial collateral ligament complex of the elbow.

Objective: To carry out an anatomical study of the medial collateral ligament, an important elbow stabilizer in different degrees of elbow flexion-extension.

Methods: Forty elbows were dissected in order to analyze the functional behavior of the anterior, posterior and transverse ligament bands during valgus stress maneuvers of the elbow in different degrees of flexion and extension. Two groups were determined; in the group GPA the posterior band of the ligament was sectioned initially, then the articular capsule and finally the anterior band; in group GAP this order was reversed.

Kinetic and kinematic evaluation of the ankle joint after achilles tendon reconstruction with free semitendinosus tendon graft: preliminary results.

Chronic rupture of the Achilles tendon (AT) is a surgical challenge and has effects on the gait. The purpose of this study was to evaluate the kinetic and kinematic parameters of the ankle joint in patients with AT rupture operated using a free semitendinosus tendon graft. Thirteen patients were analyzed 6 and 12 months after surgery in a force platform, while the movements were recorded by six infrared cameras.

Vascular density of the posterior tibial tendon: a cadaver study.

Background: Degenerative pathology of the posterior tibial tendon, a common cause of foot and ankle dysfunction, frequently affects women over 40 years of age. Its etiology is still controversial. The literature reports decreased vascularization coinciding with the most common site of the lesion, near the medial malleolus.

Pedobarometric evaluation of the normal adult male foot.

Static and dynamic pedobarometric evaluations were performed on the feet of 100 normal adult white men aged from 20 to 49 years old (mean = 29.9 +/- 6.9), using version 3.
