The Scottish Rite abduction orthosis for the treatment of Legg-Perthes disease. A radiographic analysis.

We evaluated a consecutive series of thirty-four patients who had had Legg-Perthes disease to determine the results of treatment with the Scottish Rite weight-bearing abduction orthosis. All patients had been older than six years at the time of the onset of the symptoms, had been in the fragmentation phase of the disease when they were first seen, and had had Catterall group-III or IV involvement. Although comparison of this series with those reported previously is difficult due to the variability of the presentation of data in the literature, this orthosis does not appear to offer an advantage compared with other methods of management, or with no treatment, for patients such as those whom we studied.

Congenital absence of the lung.

Four cases of congenital absence/aplasia of the lung associated with congenital vertebral anomalies are reported. Although alteration in arterial blood gas determinations and vital capacities occurred, the patients tolerated general anesthesia well.

Treatment of the displaced supracondylar fracture of the humerus (type III) with closed reduction and percutaneous cross-pin fixation.

Forty-five consecutive patients treated for displaced supracondylar fractures of the humerus, Type III, by means of closed reduction and percutaneous crossed-pin fixation, were studied retrospectively. Thirty-three were available at an average of 33 months post-injury for clinical and radiographic follow-up of the affected and nonaffected extremities. Five additional patients returned radiographs for analysis. Baumann's angle and a lateral humeral capitellar angle were assessed and found to be useful clinical guides for assessing the adequacy of maintenance of fracture reduction. Based upon Flynn's criteria, 31 of 33 patients clinically assessed had a satisfactory result. Closed reduction with percutaneous pin fixation is believed to represent a safe, reliable, and efficient method of managing this difficult fracture.

Vertebral collapse in childhood leukemia.

Leukemia is the most common form of cancer in children. At the time of initial presentation, 10% of children have normal peripheral blood counts. Appendicular skeletal involvement occurs in approximately 50% of cases. The literature does not clearly define the incidence of spinal involvement, with only a total of 31 cases located in a review of the literature. If case reports are excluded and series that reported the frequency of spinal involvement are summarized, only 16 of 615 cases had spinal involvement. In only one of 31 was it clear that the patient had a normal peripheral blood count at the time of diagnosis. This article adds to the literature two patients who had normal peripheral blood counts and spinal involvement with acute lymphocytic leukemia. Patients with leukemia may have significant symptoms and radiographic signs with normal peripheral cell blood counts at the time of initial presentation.

Preliminary experience with the Scottish Rite Hospital abduction orthosis for Legg-Perthes disease.

Containment of the femoral head within the acetabulum is now an accepted method of treatment for LCPD. Several types of ambulatory abduction orthoses have been utilized to obtain such containment. A group of 41 patients has completed treatment of LCPD by wearing an efficient and ambulatory abduction brace designated as the SRH orthosis. By following a specific treatment protocol the results have been comparable to other accepted methods of treatment. The orthosis, when utilized as described, is recommended as a method of containment. It has proven to be durable and readily fabricated with few restrictions on patient activity, few complications and good acceptance by patients and families.
