Single-Event Bilateral Modified Dunn Osteotomy for Bilateral Severe SCFE: Restoring Function in a High-Level Athlete.

Area of Science:

• Orthopedic surgery
• Pediatric orthopedics
• Hip joint biomechanics

Background:

• Slipped capital femoral epiphysis (SCFE) is a hip condition affecting adolescents.
• Bilateral and unstable SCFE present significant management challenges.
• Traditional treatments may involve multiple surgical stages.

Purpose of the Study:

• To evaluate the efficacy of a single-event bilateral modified Dunn osteotomy for severe bilateral SCFE.
• To assess clinical function and radiological outcomes in a young competitive athlete.
• To determine if this approach allows return to high-level sports.

Main Methods:

• A 13-year-old competitive basketball player with bilateral acute-on-chronic, unstable SCFE underwent surgery.
• The procedure involved a single-event bilateral modified Dunn capital realignment osteotomy and fixation.
• Postoperative follow-up included clinical assessment and radiological evaluation.

Main Results:

• At 4 years post-surgery, the patient demonstrated excellent clinical function.
• The patient successfully returned to competitive basketball.
• Good radiological outcomes were observed, indicating successful anatomical restoration.

Conclusions:

• A single-event bilateral modified Dunn osteotomy is a viable surgical option for severe bilateral SCFE.
• This procedure can yield rewarding outcomes, including restoration of hip anatomy.
• Centers with specialized hip teams and resources can consider this approach for suitable patients.
