Summary
Volar percutaneous screw fixation effectively treats scaphoid waist delayed unions, achieving high healing rates and restoring wrist function. This minimally invasive technique offers a reliable solution for nonunion scaphoid fractures.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Scaphoid waist fractures are common, with delayed unions posing treatment challenges.
- Volar percutaneous screw fixation is established for acute fractures but not widely reported for delayed unions.
Purpose of the Study:
- To evaluate the efficacy of volar percutaneous cannulated screw fixation for treating scaphoid waist delayed unions.
Main Methods:
- A cohort of 12 patients with scaphoid waist delayed union underwent volar percutaneous cannulated screw fixation.
- Patients were assessed for fracture healing, wrist range of motion, grip strength, and patient-reported outcomes.
Main Results:
- All 12 fractures achieved uneventful union.
- Post-treatment wrist flexion and extension averaged 94% and 93% of the uninjured side.
- Grip strength reached 92% of the uninjured hand, with excellent functional scores (Mayo Modified Wrist Score: 94, DASH: 9).
Conclusions:
- Volar percutaneous cannulated screw fixation is a reliable and effective surgical option for managing scaphoid waist delayed unions.
- The procedure facilitates fracture healing and leads to significant restoration of wrist function and strength.
