Intramedullary Headless Compression Screw Fixation for Metacarpal Fractures

Overview

This retrospective study evaluated 37 patients with metacarpal fractures treated using intramedullary headless compression screw (IHCS) fixation combined with a splint-free early mobilisation protocol. The technique demonstrated stable fixation, significant correction of fracture angulation, and facilitated early functional recovery without the need for postoperative immobilisation.

Background

Metacarpal fractures are common upper extremity injuries, often requiring surgical intervention when deformity or instability is present. Traditional fixation methods such as K-wire and plate osteosynthesis have limitations including infection risk, soft tissue disruption, and prolonged immobilisation. IHCS fixation offers stable internal fixation with minimal soft tissue damage, allowing early mobilisation and potentially reducing complications associated with other surgical techniques.

Data Highlights

Key Findings

• IHCS fixation achieved stable internal fixation with minimal soft tissue disruption.
• Significant correction of fracture angulation was observed postoperatively (p < 0.05).
• No postoperative immobilisation was applied; patients commenced immediate active mobilisation.
• Early functional recovery was facilitated, with patients regaining pain-free full range of motion and returning to daily activities.
• Low complication rates were reported, with no mention of implant migration or infection.
• Radiological union was achieved within the follow-up period without the need for implant removal in most cases.

Clinical Implications

IHCS fixation for metacarpal fractures provides a reliable and minimally invasive surgical option that allows for immediate postoperative mobilisation without splinting. This approach may reduce complications associated with prolonged immobilisation and soft tissue dissection, promoting faster functional recovery. Clinicians should consider IHCS fixation in appropriate patients to optimize outcomes and facilitate early return to daily activities.

Conclusion

Intramedullary headless compression screw fixation is an effective surgical technique for metacarpal fractures, offering stable fixation and enabling splint-free early mobilisation. This method supports satisfactory clinical and radiological outcomes with low complication rates.
