Fixation of first metatarsal basal osteotomy using Acutrak screw

Area of Science:

• Orthopedic surgery
• Foot and ankle reconstruction
• Surgical fixation techniques

Background:

• First metatarsal basal osteotomy is a surgical procedure to correct foot deformities.
• Internal fixation plays a crucial role in stabilizing osteotomies.
• The Acutrak screw is a type of surgical implant used for bone fixation.

Purpose of the Study:

• To evaluate the clinical and radiological outcomes of internal fixation for first metatarsal basal osteotomy.
• To assess the efficacy of the Acutrak screw in stabilizing this type of osteotomy.

Main Methods:

• A retrospective study of 37 feet undergoing basal closing wedge osteotomy stabilized with Acutrak screws.
• Minimum follow-up of 18 months.
• Assessment of screw position, complications, hallux valgus, intermetatarsal and metatarsal declination angles, and bony union.

Main Results:

• 79% of patients achieved excellent or good American Orthopaedic Foot & Ankle Society (AOFAS) scores.
• Significant reduction in preoperative intermetatarsal (17.3° to 10.3°), hallux valgus (38° to 14.6°), and metatarsal declination angles (22.5° to 20.4°).
• All cases achieved clinical and radiological bony union.

Conclusions:

• The Acutrak screw provides stable fixation for first metatarsal basal osteotomy.
• The technique demonstrates minimal loss of position at the osteotomy site.
• This method is effective for correcting hallux valgus and related deformities.
