Abstract
Introduction
Hip dysplasia is the most common congenital deformity of the musculoskeletal system. This is a pathology that brings the hip joint from subluxation to dislocation.
Frequency of hip dysplasia − 16 children per 1000 newborns.
Materials and Methods
Diagnostic methods of research are X-ray inspection which is necessarily carried out at internal rotation (rotation) of an extremity as lateral rotation of a hip on the radiograph always increases an angle of a valgus deviation of a neck. Surgical treatment is performed in the subclavian area of the femur. An external fixation device is applied and a corrective corticotomy is performed, and valgus deformity and anteversion are eliminated. The duration of treatment is 2.5–3 months.
Results
Frequency of hip dysplasia − 16 children per 1000 newborns.
We perform about 30 operations a year, including 60% girls and 40% boys.
In addition, valgus deformity can be traced -
-
- in cerebral palsy
-
- after polio
-
- at progressing muscular dystrophies
-
- tumor in the area of the epiphyseal cartilage
At insufficient stability in a hip joint at insufficiently expressed roof of an acetabulum of rotational deformation of a neck of a hip, for prevention of a coxarthrosis and normalization of a ratio of articular ends operation detorsion-varying subvertebral corticotomy of a femur is shown.
Conclusions
The operation is minimally invasive, with accesses of 5–6 mm, anatomical and topographical features are taken into account, which will eliminate damage to tissues, nerve trunks and the circulatory system.
