Single Flexible Nailing of the Humerus for Recurrent Bone Cysts

Area of Science:

• Orthopedic Surgery
• Pediatric Orthopedics
• Musculoskeletal Oncology

Background:

• Unicameral bone cysts (UBCs) in the proximal humerus present a risk of pathologic fractures.
• Current management strategies aim to prevent fractures and restore bone integrity.

Purpose of the Study:

• To evaluate the efficacy of single flexible intramedullary nailing combined with curettage and grafting for treating humeral UBCs.
• To assess the technique's ability to safeguard the bone and enable early patient activity.

Main Methods:

• Surgical technique involves curettage of the UBC, bone grafting, and fixation with a single flexible intramedullary nail.
• The procedure emphasizes technical simplicity, reduced surgical time, and avoidance of extensive dissection.
• Fluoroscopic guidance is used for accurate nail placement.

Main Results:

• Single flexible nailing provides stable internal fixation for humeral UBCs.
• The technique facilitates early motion and return to activity.
• It is effective even in cases of cyst recurrence, acting as a prophylactic fixation strategy.

Conclusions:

• Curettage and single flexible intramedullary nailing is an effective treatment for pediatric humeral UBCs.
• This approach allows patients to continue activities, managing the cyst conservatively.
• The technique offers advantages in surgical simplicity and patient recovery.
