SURGICAL TREATMENT OF PATIENTS WITH SPINAL DEFORMITIES WITH SHORTENING OF THE LOWER LIMB

Abstract

Determination of the optimal diagnostic and treatment strategy in patients with scoliosis and having an anatomic shortening of the lower limb. Surgical correction of scoliosis held 8 to patients with lower limb shortening caused by congenital dislocation of the hip (n = 3), anatomic shortening of the lower extremities due to the hip (n = 1), the shin bone (n = 4). Shortening before correction and fixation of scoliosis ranged from 6 to 14 cm, after surgery on the spine has been reduced by 2-4 cm achieved reduction or removal of pelvic obliquity. The second stage, after 8-12 months, performed surgery to address shortening of the lower extremity. Osteotomy of the femur with the imposition of a spoke - rod device held 4 tibial osteotomy with the imposition of external fixation device Spoke - and 4 patients and in the subsequent limb lengthening was performed by compression-distraction osteosynthesis. After the dorsal stabilization and fixation of the spine scoliosis correction averaged 64% (from 76 to 27 degrees), the value of breast/thoracolumbar kyphosis after surgery failed to bring to the physiological (average 43 degrees). Misalignment of the pelvis is reduced by 67% (from 24 to 8 degrees), which reduced the shortening of the lower limb by an average of 3 cm (compensation relative shortening by reducing or eliminating the distortion of the pelvis). Further compensation shortening held on the second stage of treatment, representing an osteotomy and subsequent elongation of the femur or tibia bones by transosseous compression-distraction osteosynthesis by Ilizarov. Multi-stage treatment reduced the degree of spinal deformity, to normalize the balance of the body, restore the function of distance without the use of orthotic devices and means of support.
