Multiple Flexor Tendon Ruptures Caused by Neglected Volar Lunate Dislocation: A Case Report.

Objective: To describe the clinical and paraclinical features and the surgical outcomes of multiple flexor tendon ruptures in a patient with neglected lunate dislocation. Methods: A case report. Results: Lunate dislocation is rare and easily missed at initial diagnosis. Delayed/neglected cases can lead to wrist osteoarthritis, median nerve involvement, and flexor tendon injury. We report a patient with multiple flexor tendon ruptures associated with a 4-year neglected lunate dislocation. The patient underwent flexor tendon reconstruction using an autologous palmaris longus graft combined with lunate excision. At 1-year follow-up, finger motion was good and there was no evidence of wrist osteoarthritic change. Conclusion: Multiple flexor tendon ruptures associated with neglected lunate dislocation are rare. Surgery achieved successful functional recovery, allowing the patient to return to everyday work.
