A procedure is described for reconstruction of the oblique retinacular ligament using a small tendon graft in a spiral fashion to act as a dynamic tenodesis to restore distal interphalangeal extension and to restrain proximal interphalangeal hyperextension. The method has been uniformly successful in the treatment of post-traumatic "swan-neck" or "mallet" deformity. Although the concept is simp...

Background: Plastic deformity is a fixed deformity of bones after application of force which is in contrast to elastic deformity, so it remains unchanged. It is a rare condition and is seen more commonly in upper extremity (forearm). Inability to recognize it causes limitation of motion and remaining of angular deformity. It occurs more commonly in children because of flexibility of their bones...

OBJECTIVE To evaluate the association between thorax deformities, panic disorder, and joint hypermobility METHODS The study includes 52 males diagnosed with thorax deformity, and 40 healthy male controls without thorax deformity, in Tatvan Bitlis and Isparta, Turkey. The study was carried out from 2004 to 2006. The teleradiographic and thoracic lateral images of the subjects were evaluated to...

objectives: skeletal-muscular disorders affect the biomechanics of the human body, especially the lower extremity, with a negative effect on the biomechanics of exercise. the main aim of this study was to evaluate the effect of fatigue on the kinematic variables of knee joints during countermovement jumps in female students of physical education with valgus knee deformity.  methods: fifteen sub...

Pectus excavatum is the most common thoracic deformity, and there are many surgical methods used in clinic. Almost all previous operations were limited to one kind of procedure. The completion operation will directly affect effect treatment pectus excavatum. After long-term clinical practice, we found that can be treated with multiple at same time. use these completely correct deformity achieve...

Trophic ulcers (or 'plantar ulcers' ) may occur on structurally normal but anaesthetic feet, and these have been called the 'dynamic type' ulcer, by Price ( 1 963) . They occur on pliant feet, heal rapidly with rest, and can be prevented by appropriate shoes. On the other hand, the presence of a deformity may promote recurrent and intractable ulcers even when shoes are worn. Ulcers associated w...

AIMS The aim of this study was to examine the real time in vivo kinematics of the hip in patients with cam-type femoroacetabular impingement (FAI). PATIENTS AND METHODS A total of 50 patients (83 hips) underwent 4D dynamic CT scanning of the hip, producing real time osseous models of the pelvis and femur being moved through flexion, adduction, and internal rotation. The location and size of t...

Vertebral development is a dynamic and complicated process, and defects can be caused by a variety of influences. Spinal curvature with no known cause (idiopathic scoliosis) affects 2-3% of the human population. In order to understand the etiology and pathogenesis of complex human skeletal defects such as idiopathic scoliosis, multiple models must be used to study all of the factors affecting v...

congenital radial club hand is an intercalary or terminal deficiency characterized by radial deviation of the hand, marked shortening of the forearm, and generalized underdevelopment of the extremity. we performed centralization of the ulna in 12 forearms of 10 patients with severe congenital radial club hands. the mean follow up was 42 months after operation (24 to 68 months). the mean age at ...
