Loss of joint motion is a common complication of limb lengthening despite newer methods of incremental bone elongation. A pilot canine study has demonstrated that 30% femoral lengthening causes reproducible knee cartilage injury manifest by frank loss of cartilage substance or fibrillation. This study was undertaken to examine the potential of knee joint(More)
Between June 1987 and June 1992, 62 tibiae in 52 patients underwent lengthening by using the Ilizarov technique. Follow-up was from 18 months to 5 years. The mean age at surgery was 12.9 years (range, 5-19). The etiology of limb shortening was congenital in 53 and acquired in nine tibiae. Thirty-five tibiae had bifocal and 27 had unifocal treatment.(More)
Limb-length discrepancy is a relatively common problem in children. Limb lengthening has traditionally been indicated for projected or actual length discrepancies exceeding 5 cm. Rapid distraction methods of limb lengthening, introduced by Codivilla and popularized by Wagner, have had unacceptably high complication rates. Gradual incremental distraction(More)
We report the results of 36 femoral lengthenings in 30 consecutive patients using the Ilizarov technique. Patient age at surgery in 19 boys and 11 girls averaged 13.4 years (range, 5-18). Minimum follow-up was 2 years. The etiology of femoral shortening was congenital in 21 femora and acquired in 15. Twelve femora underwent concomitant correction of(More)
OBJECTIVES a) To determine if antidiuretic hormone (ADH) is elevated in patients undergoing spinal fusion, especially in those who have clinical evidence of syndrome of inappropriate antidiuretic hormone (SIADH); b) to evaluate the relationship between ADH secretion and the secretion of atrial natriuretic peptide (ANP). SETTING Tertiary care pediatric(More)
Previously published series of surgery for late-onset tibia vara reported a significant number of complications and fair or poor results. Obesity in many of these patients makes surgical intervention an even more daunting prospect. Circular external fixation is applicable to almost any limb size and allows weight bearing as tolerated, with gradual(More)
Despite the standard available pediatric developmental scales and popular lore that girls walk at an earlier age than boys, no large-scale evaluation of the age of onset of independent ambulation has been previously published. The purpose of this study was the prospective epidemiologic evaluation of a large heterogeneous group of normal children to(More)
PURPOSE Tibial osteotomy is used to treat a variety of orthopedic conditions, including reduction in pain and improvement of deformity and function. In templating for surgery, accurate radiographic measurement aids in planning for correction. The purpose of our study was to examine the effect of internal rotation and external rotation on measurement of(More)
OBJECTIVE To compare the incidence of joint hypermobility and prolapse in incontinent and continent women with Ehlers-Danlos syndrome (EDS). METHODS Forty-six patients with EDS were evaluated by history and physical examination. The degree of joint mobility of shoulder, elbow, wrist, hip, knee, and ankle was evaluated by orthopedic surgeons and physical(More)
Eighteen limb segments in eight patients with lower limb deformities secondary to metabolic bone disease underwent correction using the Ilizarov technique. Eleven femora and seven tibiae were treated for deformities with magnitudes of 12 degrees to 58 degrees. Total treatment time averaged 12 weeks from application to removal of the fixator. With one(More)
