Abstract

Abstract: BACKGROUND: Developmental dislocation of the hip in children is a common clinical orthopedic hip disease in children. The short-term follow-up effect of Salter pelvic osteotomy is satisfactory. At present, there is still no medium- and long-term clinical follow-up research in China.
OBJECTIVE: To explore the medium- and long-term clinical effects and complications of Salter pelvic osteotomy in the treatment of developmental hip dislocation in children.
METHODS: A retrospective analysis of 65 cases (70 hips) of children with developmental hip dislocation admitted from January 2010 to March 2015 in First Affiliated Hospital of Guangzhou University of Chinese Medicine was performed with open reduction, Salter pelvic osteotomy or Salter pelvic osteotomy combined with femur proximal osteotomy (locking compression plate fixation) treatment. According to Tonnis scale, there were degree I in 10 hips, degree II in 17 hips, degree III in 12 hips, and degree IV in 31 hips. Preoperative and postoperative central margin angle, acetabular index, Sharp angle and acetabular depth were observed. The postoperative efficacy was evaluated by McKay function standard and Severin standard of X-ray films.
RESULTS AND CONCLUSION: (1) All 65 patients were followed up for 5.1-10.2 years. (2) The postoperative acetabular index and Sharp angle were significantly lower than those before the operation; and the central margin angle and acetabular depth were significantly increased compared with the preoperative data. The differences were statistically significant (P < 0.05). (3) In last follow-up after operation, according to Mckay functional evaluation criteria, the excellent and good rate was 97%. According to the final X-ray Severin evaluation standard, the excellent and good rate was 90%. (4) Necrosis of the affected femur occurred in three patients, relocation of the hip in one patient, proximal femoral deformity in one patient, and sensory abnormalities in the affected limb in one patient. (5) The Salter pelvic osteotomy for children with developmental dislocation of the hip has a satisfactory medium- and long-term clinical effect, which can effectively improve the patient’s acetabular coverage and improve hip function.
