Surgical treatment of vascular malformations of the extremities in children and adolescents.

The treatment of vascular malformations (VM) of the extremities is controversial. Six patients with large, localized, symptomatic VMs of the extremities underwent surgical excision. In five cases abnormal vessels were apparent under the skin; in two of these there was also red discoloration of the skin secondary to skin involvement. Magnetic resonance imaging was the most helpful imaging modality in evaluating these patients. Subfascial resection was performed in five cases. Muscle was involved in four patients and was removed in all four cases. At follow-up, there was improvement in symptoms and function with no clinically apparent recurrence an average of 30 months following the operation. There was improvement in pain intensity from an average of 4.3 on a scale of 1 to 10 before surgery to 1.3 after surgery. Surgical excision of localized VMs that are extensive and include fascia and muscle, as appropriate, can successfully improve pain and function without evidence of recurrence at 1 to 5 years of follow-up.

Late diagnosis of hip dislocation in infants.

To determine the rate of late diagnosis of hip dislocations in infants, 26,455 newborns were examined by or under the supervision of the authors from 1976 to 1988. The incidence of examinations positive for dislocated or dislocatable hips was 3.8/1,000. The incidence of known late cases was 4/26,455 (0.2/1,000). Because follow-up of all initial examinations was not possible, this rate is probably artificially low. Hip screening programs with direct pediatric orthopaedic supervision can be successful, but late cases will still occur.

Abdominal reflexes.

Examination of the superficial abdominal reflexes in patients thought to have idiopathic scoliosis has been considered possibly beneficial for deciding who should have magnetic resonance imaging to rule out syringomyelia. The purpose of this study was to determine what is normal for this examination. Thirty normal adolescents and 35 normal young adults underwent testing of the superficial abdominal reflexes and the patellar and Achilles deep tendon reflexes. Each test was repeated two times. Thirty-nine (60%) subjects had bilaterally equal abdominal reflexes. Nine (14%) subjects had asymmetric reflexes, and seven (11%) subjects had no reflex in at least one quadrant. No subjects had reflexes present on one side and absent on the other. Ten (15%) subjects had absence of the abdominal reflexes in all quadrants. Sixteen (25%) subjects had extinguishing of the reflex in at least one quadrant as the test was repeated. Eleven of these had asymmetric or partially absent reflexes initially. In contrast, the patellar and Achilles reflexes were more consistent. The patellar reflexes were bilaterally equal in 52 (85%), asymmetric in eight (13%), and absent in one (2%). The Achilles reflexes were bilaterally equal in 59 (97%), asymmetric in one (2%), and absent in one (2%). The finding of abdominal reflexes consistently present on one side and consistently absent on the other side did not occur in our normal subjects. This finding might warrant further workup if found in a patient with scoliosis. Other variations in abdominal reflex testing such as asymmetries, absent in some quadrants, and absent in all quadrants are fairly common in normal subjects.
