AI Article Synopsis
- Hip distraction helps relieve joint pressure in patients with Legg-Calvé-Perthes disease, potentially aiding in the healing of damaged areas.* -
- In a study involving 29 patients, 93% experienced an improvement in range of motion after treatment with an external fixator, and 86% reported being pain-free at follow-up.* -
- The findings suggest that hip distraction without soft tissue release is a promising treatment for patients who are unlikely to benefit from traditional therapies.*
Article Abstract
Background: Hip distraction in Legg-Calvé-Perthes disease unloads the joint, which negates the harmful effect of the stresses on the articular surface, which may promote the sound healing of the areas of necrosis.
Methods: Nonarticulated arthrodiastasis without soft tissue release using an Ilizarov external fixator was applied to 29 patients with Legg-Calvé-Perthes disease (older than 8 y at onset and lateral pillar type C or B).
Results: Follow-up period ranged from 2.5 to 11 years with an average of 7.5 years. Twenty-seven cases (93%) had improvement of the range of motion postoperatively. Preoperatively, all patients had constant pain, whereas at last follow-up 26 (86%) patients had no pain and 3 had an improvement. Stulberg classification was applied to 21 cases who reached skeletal maturity at last follow-up: 9 cases were type II, 7 cases were type III, 4 cases were type IV, and 1 case was type V.
Conclusions: Nonarticulated hip distraction without soft tissue release seems to be a valid treatment option in cases with Legg-Calvé-Perthes disease where poor results are expected from conventional treatment.
