A double-closed wedge broken-line osteotomy for cubitus varus deformity

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Skeletal Deformity Correction

Background:

• Cubitus varus, a common elbow deformity, can result from various causes and impacts upper limb function.
• Existing osteotomy methods for cubitus varus correction have limitations.
• A need exists for improved surgical techniques offering better deformity correction and reliable healing.

Purpose of the Study:

• To introduce and evaluate a novel double-closed wedge broken-line osteotomy for treating cubitus varus.
• To assess the clinical and imaging outcomes of this new osteotomy technique.
• To determine the efficacy, safety, and complication profile of the double-closed wedge broken-line osteotomy.

Main Methods:

• A prospective case series involving 9 patients with cubitus varus treated with the double-closed wedge broken-line osteotomy.
• Preoperative and postoperative assessment of the humeral elbow-wrist angle and elbow range of motion (ROM).
• Evaluation of osteotomy healing, functional recovery, and complications over a median follow-up of 23.2 months.

Main Results:

• The median humeral elbow-wrist angle improved significantly from -14.27° to 15.15° postoperatively.
• Postcorrection clinical and imaging parameters were comparable to the unaffected contralateral side.
• All patients achieved their preoperative elbow ROM with the implemented rehabilitation program, demonstrating reliable osteotomy healing and a low incidence of complications.

Conclusions:

• The double-closed wedge broken-line osteotomy provides a larger cancellous bone contact surface, facilitating satisfactory deformity correction.
• This technique demonstrates reliable osteotomy healing and a low complication rate in the treatment of cubitus varus.
• The improved osteotomy method offers a promising solution for cubitus varus correction with good functional outcomes.
