This is a report of a case of double acromion and double coracoid and a commentary on the comparative anatomy and embryology of the shoulder. Congenital elevation of the scapula, ossification of the transverse scapular ligament, clasp-like superior border of the scapula, coracoclavicular joint, coracoclavicular bridge, coracosternale bone, os acromiale, elongated acromion, convex glenoid, hypoplasia of the inferior border of the glenoid, dentated glenoid, infrascapular bone, and notched inferior angle of the scapula are other anomalies of the scapula reported in the literature.

Combined staged anterior and posterior correction and fusion of the spine in scoliosis following poliomyelitis.
The problems with severe forms of scoliosis following poliomyelitis include the associated muscle imbalance, soft tissue contractures and pelvic obliquity. Such deformities militate against optimal correction and maintenance of that correction and their treatment is often marred by pseudarthroses. Seventeen patients with an average curve of 93 degrees have been treated and followed for up to 38 months. ⋯ No pseudarthroses were seen when the Harrington rod was used. Great care must be taken if halo-pelvic traction is to be used for patients with pelvic obliquity, for preliminary correction halo-femoral traction will often be adequate. In the more severe forms of paralytic scoliosis a combined staged anterior and posterior correction and fusion should be considered if the aim is maximal correction of the scoliosis and avoidance of pseudarthroses.

Case ReportsScheuermann's juvenile kyphosis. A histologic study.
The case histories and gross and microscopic findings of two adolescent patients with Scheuermann's kyphosis demonstrate that the anterior longitudinal ligament is bowstrung across the apex of the hyphosis. The microscopic findings include markedly irregular end plates and end plate disruption with protrusion of disk material into the vertebral body. ⋯ The intervertebral disk is interpreted as normal both by routine histology and electron microscopy. It is postulated that Scheuermann's kyphosis may be secondary to vertebral osteoporosis occurring during the juvenile period rather than to an intrinsic abnormality in the intervertebral disk or ring apophysis.

Case ReportsLuxatio erecta of the hip. An interesting case report.
This is a case report of an inferior dislocation of the hip in a 5 1/2-year-old child, characterized by acute flexion with slight abduction of the hip and flexion of the knee. The dislocation is reducible by traction in a cephalad direction, gradual extension and internal rotation of the hip.
