Staged bilateral Colonna arthroplasty in an adolescent within a 10-month difference: A case report with a literature review

Colonna capsular arthroplasty is an intervention that has gained interest in recent years by adopting the controlled hip dislocation approach. In this report, we present the case of a 15-year-old adolescent with a history of congenital bilateral hip dislocation without prior treatment. She presented with significant symptoms, pain after activity, bilateral Trendelenburg gait, more remarkable on the left, symmetrical lower extremity length, and altered range of hip motion. Radiographs showed a Crowe IV high hip dislocation in a Sommerville stage III. Surgical treatment was performed, with modified Colonna capsular arthroplasty, associated with femoral shortening osteotomy and lateral acetabular augmentation, bilaterally, with 10 months between the two hips. In the 4-year follow-up, the patient was without coxalgia, walking without Trendelenburg gait, with a painless complete range of motion, without lower limb difference, and with high patient satisfaction. Radiographic evaluation showed centered hips with preserved joint space. Based on the result, we can point out that modified Colonna capsular arthroplasty can once again be an effective surgical technique, with excellent functional results, even in bilateral cases, accompanied by adequate rehabilitation and strict clinical and radiographic follow-up.
