Anterior slip of the capital femoral epiphysis. Report of a case and discussion.
A rare case of anterior slip of the capital femoral epiphysis demonstrates that the mechanism of the posterior, inferior slip of the capital femoral epiphysis is a combination of weight bearing in the frontal plane and muscle pull in the horizontal plane. Sudden violent motions cause some of the unusual positions of acute slip.
Long thoracic nerve injury due to an electric burn.
A 19-year-old white man was burned over 7.5% of his body when he sustained an electric injury from a transformer. There was no associated fall or loss of consciousness. Debridement and grafting were required. The patient had some transient weakness of the muscles of his right arm associated with lower cervical nerve-root injury. This subsequently improved. He also was found to have paralysis of the serratus anterior muscle, with winging of the scapula due to long thoracic nerve injury. This has not improved. A surgical procedure suggested to improve function of the shoulder was rejected by the patient. This is only the second case reported of long thoracic nerve injury due to an electric burn of which we are aware.
The role of scoliosis and pelvic obliquity on functional disability in myelomeningocele.
A retrospective analysis of 39 patients with myelomeningocele over age 16 was done to determine the effects of scoliosis and pelvic obliquity on their ambulatory ability and function. Although primarily dependent on neurologic level, prevention of an unbalanced spine and maintenance of ambulatory status also appeared to correlate closely with a curvature less than 40 degrees and a pelvic obliquity less than 25 degrees. All ambulators, regardless of neurologic level, had a pelvic obliquity of 25 degrees or less. Of the 19 ambulators, all but two had curvatures of 40 degrees or less. Ten of the 11 unbalanced sitters had a curvature of 35 degrees or more and a pelvic obliquity greater than 25 degrees. The quality of life style also appeared to correlate well with the severity of scoliosis and pelvic obliquity. Sixteen untreated patients with progressive curvatures prior to age 16 appeared to have insignificant curve progression past age 16. Twelve patients underwent posterior fusion in situ. This procedure alone is not recommended for the treatment of scoliosis associated with myelomeningocele because of the high morbidity.
