Weight bearing in Perthes' disease

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Pediatric Bone Diseases

Background:

• Perthes' disease affects the proximal femoral epiphysis, potentially leading to long-term hip dysfunction.
• Varus-derotation femur osteotomy is a surgical intervention aimed at improving hip joint congruency in Perthes' disease.
• Postoperative management strategies, including weight-bearing status, are crucial for optimizing surgical outcomes.

Purpose of the Study:

• To evaluate the impact of postoperative weight-bearing status on the outcomes of varus-derotation femur osteotomies in patients with Perthes' disease.
• To compare the effectiveness of allowing immediate weight bearing versus applying non-weight-bearing braces post-surgery.

Main Methods:

• A retrospective analysis of 82 patients treated for Perthes' disease between 1974 and 1984.
• Patients underwent varus-derotation femur osteotomy.
• Two postoperative protocols were compared: immediate weight bearing (30 cases) and non-weight-bearing braces (52 cases).

Main Results:

• The study analyzed 82 cases of varus-derotation femur osteotomies for Perthes' disease.
• No significant difference in end results was observed between patients who were allowed weight bearing and those treated with non-weight-bearing braces.
• Risk factors were considered in the comparison of the two treatment groups.

Conclusions:

• Postoperative non-weight-bearing bracing does not appear to influence the final outcomes after proximal femur osteotomy for Perthes' disease.
• The findings suggest that weight-bearing status may not be a critical factor in the long-term success of this surgical procedure.
