Calcaneonavicular coalition resection with fat graft.

Area of Science:

• Orthopedic surgery
• Foot and ankle reconstruction
• Biomaterials in surgery

Background:

• Calcaneonavicular coalitions cause significant foot and ankle pain and functional impairment.
• Current standard care for disabling symptoms involves surgical excision and graft interposition.
• Recurrent symptoms and reossification are potential complications of surgical treatment.

Purpose of the Study:

• To provide a detailed, step-by-step surgical technique for calcaneonavicular coalition treatment.
• To describe the resection of calcaneonavicular coalitions.
• To explain the interposition of an autologous fat graft to prevent reossification.

Main Methods:

• Preoperative imaging (MRI or CT) is crucial for assessing coalitions and foot alignment.
• Surgical technique involves complete coalition resection using fluoroscopy and precise osteotome use.
• Autologous fat graft harvested from the proximal medial thigh is utilized for interposition.

Main Results:

• The described technique aims for complete resection of the calcaneonavicular coalition.
• Interposition of autologous fat aims to prevent reossification and recurrence.
• The procedure is intended to alleviate pain and restore function in affected patients.

Conclusions:

• Surgical resection with autologous fat graft interposition is a viable treatment for calcaneonavicular coalitions.
• Careful preoperative planning and meticulous surgical technique are essential for optimal outcomes.
• This approach addresses the challenges of coalition removal and prevention of reossification.
