Background.Surgical treatment of destructive dislocations is problematic, and controversial. Treatment options range from active monitoring to complex multistage reconstruction protocols.Materials and methods.The results of treatment of 17 children with disruptive dislocation of the hip (class IV according to the Choi classification) are presented. The mean age at which treatment was started was 6.3 ± 0.5 years (range: 3-9 years). Treatment strategies included formation of the weight-bearing contact of the proximal femur and acetabulum and ilium osteotomy using an Ilizarov frame. The follow-up period lasted from 2 to 11 years. Clinical results were assessed using Colton’s criteria. Assessment of the radiology findings included the anatomy relations and congruence of the articular surfaces. The patients were divided into two groups, according to age, for data analysis.Results.The majority (88%) of the children had positive anatomical and functional outcomes. The functional results were good (12-15 points), satisfactory (9-11 points), and unsatisfactory (8 points) for 3, 5, and 1, respectively, among 3-6 year olds and 2, 6, and 0, respectively, among 7-9 year olds. The distribution of joint congruence types I, III, and IV was 2, 4, and 3, respectively, in the younger group and 1, 6, and 1, respectively, in the older group.Conclusion.The use of reconstructive surgery using the Ilizarov apparatus in children with a defect of the proximal femur creates conditions for the adaptation of incongruent articular components without causing decompensation of the joint.
Introduction. Avascular necrosis of the femoral head complicates the surgical treatment of hip dysplasia and aggravates the prognosis. Aim. We studied the immediate and medium-term results of reconstructive treatment in 18 children with hip dysplasia complicated by avascular femoral head necrosis, which developed after closed repositioning of a congenitally dislocated femur. Material and methods. Average age at the time of operation was 4.2 0.2 years. The patients were divided into two groups. Group 1 included 12 children with hip subluxation who underwent extra-articular reconstructions on articular components, spinal tunneling of the neck and head, and hardware unloading of the joint and group 2 included six patients with hip dislocation in whom an additional open reduction was performed. Functional results were estimated using DAubigne-Postel classification, whereas X-ray results were evaluated using Kruczynski classification. Results. Duration of observation was 37 years (average, 4.2 0.3 years). Functional results were good (1518 points) in nine joints in group 1, satisfactory (1214 points) in three joints in group 1 and five in group 2, and unsatisfactory (11 points) in one joint in group 2. X-ray results were good in six joints in group 1, satisfactory in six joints in group 1 and five in group 2, and unsatisfactory in one joint in group 2. Conclusions. Extra-articular reconstructive and stimulatory interventions combined with hardware decompression helps improve the shape and structure of the femoral head, and formation of congruent articular surfaces in children with subluxation of the thigh complicated by avascular necrosis.
Background. The value of joint-sparing reconstructive procedures in patients with osteoarthritis in a dysplastic hip is controversial. The study aimed to evaluate the immediate and mid-term results of reconstructive interventions performed in patients with this pathology. Material and Methods. The treatment results of 30 patients aged 1440 years with osteoarthritis in the dysplastic hip were analyzed. The mean follow-up time was 6.81.5 years in group 1 and 4.10.7 years in group 2. The clinical condition and treatment results were assessed by DAubigne-Postel, Severin, Tonnis criteria, and the Ilizarov Center system. In all cases, extra-articular reconstructive procedures were performed on both articular components. Results. The patients were divided into two groups by age. In group 1 (1418 years), the functional result was 16.00.5 points. According to the Severin criteria, the joints were distributed as follows: Ia, 7; IIa, 7; IIb, 2; and III, 3. The degree of hip osteoarthritis did not change in 13 joints. Osteoarthritis progressed in one joint, and arthritic changes regressed in four joints. The treatment results according to the criteria of the RSC VTO were good in 14 joints, satisfactory in 5, and unsatisfactory in 1. In group 2 (18 years, n = 11), the functional result was 15.00.4 points. The distribution of joints according to the Severin criteria was as follows: Ia, 3; IIa, 6, and III, 2. The degree of osteoarthritis did not change in 10 joints. Osteoarthritis progressed in one joint. The treatment results according to the criteria of the Ilizarov Center were good in seven joints, satisfactory in three, and unsatisfactory in one. Conclusion. The differentiated use of joint-sparing reconstructive procedures makes it possible to slow down the progression of the pathological process in the joint even in patients with developed osteoarthritis and, in some cases, to use them as a temporary alternative to endoprosthesis in adolescents and young adults.
