Anatomy of the Elbow Each tunnel is lined internally by a synovial sheath and separated from one another by fibrous septa.. The complex of the medial collateral ligaments of the ankle joint is collectively called deltoid ligament.It attaches the medial malleolus to multiple tarsal bones. Sprengel deformity, or congenital elevation of the scapula, is a complex deformity of the shoulder and is the most common congenital shoulder abnormality.An initial diagnosis can often be made on radiographs, but CT or MRI is often necessary to evaluate the details of the abnormality. [1] The signal then goes through the ventral rami and down the root ganglions of C5, C6, C7, C8, and T1 (which together form the brachial plexus). Usually, surgical treatment with excision of the coalition is required.

Proximally, the smooth convex surface of the scaphoid articulates with the distal radius. Tarsal coalition describes the complete or partial union between two or more bones in the midfoot and hindfoot.Tarsal coalition refers to developmental fusion rather than fusion that is acquired secondary to conditions such as rheumatoid arthritis, trauma or As with any tarsal coalition, non-operative management may allow some improvement in symptoms initially, but they usually return. The scaphoid can be divided into proximal and distal poles. Negative variance is when the ulna is 2.5 mm than the radius at the DRUJ 1.
