[Several causes of complications of the surgical treatment of congenital hip dislocation].

The article is devoted to revealing of the causes of complications in children with congenital dislocation of the hip. 42 patients have undergone roentgenological, electrophysiological and neurological examinations; 32 of them had complications following surgical treatment of the dislocation of the hip. In the patients with complications disturbances in the structure of the lumbosacral section of the spine and neurological changes have been revealed. Reduced excitability of the motoneurons of the spinal cord has also been observed in these patients. In 10 children with satisfactory results the deviations in the structure of the lumbosacral section of the spine were insignificant, while gross neurological changes were not revealed. The authors have arrived at the conclusion that the main causes determining the results of surgical treatment are the initial state of the neuromuscular apparatus and dysplasia of the vertebral column structures. That is why in the patients with disturbances it is necessary to carry out adequate conservative therapy directed at improvement of the metabolism of the neuromuscular structures both before the operation and during the postoperative period, e.g. 2-4 times a year according to the expression of the neurological disturbances.
