Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Trauma Surgery
Background:
- Lunate dislocation is an uncommon wrist injury often missed during initial diagnosis.
- Neglected lunate dislocations can result in severe complications, including wrist osteoarthritis, median nerve issues, and flexor tendon damage.
Purpose of the Study:
- To present the clinical and paraclinical characteristics of multiple flexor tendon ruptures.
- To describe the surgical outcomes in a patient with a long-standing, neglected lunate dislocation.
Main Methods:
- A case report detailing a patient with a 4-year neglected lunate dislocation and associated multiple flexor tendon ruptures.
- Surgical management involved flexor tendon reconstruction using an autologous palmaris longus graft and lunate excision.
Main Results:
- The patient underwent successful flexor tendon reconstruction and lunate excision.
- At one-year follow-up, the patient demonstrated good finger motion and no signs of wrist osteoarthritis.
Conclusions:
- Multiple flexor tendon ruptures secondary to neglected lunate dislocation represent a rare clinical scenario.
- Surgical treatment resulted in a successful functional recovery, enabling the patient to resume daily work activities.
