We report two patients with permanent dislocation of the proximal tibiofibular joint and no history of trauma. Both needed operation, one for persistent pain and the other for common peroneal nerve involvement, and both had a good result.

aims of the study: endometriosis is a prevalent gynecologic disorder in young women at reproductiveage but the underlying risk factors have not identified yet in iran and other neighboringcountries. persistent exposure to environmental endocrine disrupting chemicals (edcs) in particulardioxins, pahs and polychlorinated biphenyls (pcbs) with xenoestrogenic potentials have beenhypothesized in the...

Joint-stock cooperative company is not recognized in Commercial Code of Iran and the amendment bill of the Commercial Code adopted in 1968. This business entity has a unique description because of both being cooperative and having joint stock. It is a joint-stock company that is chartered based on Commercial Code of Iran, amendment bill of the Commercial Code adopted in 1968, and Principle 44 o...

Although common, AC joint injuries and their treatments are not benign. The injury itself and both nonsurgical and surgical treatments may result in complications yielding persistent pain, deformity, or dysfunction. Sternoclavicular joint injuries are far less common and are typically the result of higher energy trauma. As such, the associated complications may be more serious. Familiarity with...

We address the issue of semiparametric efficiency in bivariate regression problem with a highly persistent predictor, where joint distribution innovations is regarded an infinite-dimensional nuisance parameter. Using structural representation limit experiment and exploiting invariance relationships therein, we construct invariant point-optimal tests for coefficient interest. This approach natur...

The rank-k numerical range has a close connection to the construction of quantum error correction code for a noisy quantum channel. For noisy quantum channel, a quantum error correcting code of dimension k exists if and only if the associated joint rank-k numerical range is non-empty. In this paper the notion of joint rank-k numerical range is generalized and some statements of [2011, Generaliz...

OBJECTIVES Early therapy improves outcomes in rheumatoid arthritis (RA). It is therefore important to improve predictive algorithms for RA in early disease. This study evaluated musculoskeletal ultrasound, a sensitive tool for the detection of synovitis and erosions, as a predictor of outcome in very early synovitis. METHODS 58 patients with clinically apparent synovitis of at least one joint...

Persistent dislocation of the elbow after a fracture of the coronoid process is a difficult problem. We have performed an open reduction with reconstruction of the coronoid by an osteocartilaginous graft from the ipsilateral olecranon for two patients. Both achieved a painless, stable joint with a functional range of movement. The joint surface of the graft has a similar curve to that of the co...

 Background: Generalized joint hyper mobility predisposes some individuals to a wide variety of musculoskeletal complaints. Given the critical role of scapular position in function of shoulder, the aim of this study was to compare scapular position between persons with and without general joint hyper mobility. Methods: By nonprobability sampling 30 hyper mobile persons at average of 22.86 ±2.77...
