Summary
Flexor tendon ruptures can occur after hook of the hamate fractures. Surgical treatment involving hook excision and tendon repair yields good outcomes, though some motion limitation may persist.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- Hook of the hamate fractures can lead to secondary flexor tendon ruptures.
- Diagnosis of the fracture is often missed before the tendon rupture occurs.
Purpose of the Study:
- To describe outcomes of surgical treatment for flexor tendon ruptures secondary to hook of the hamate fractures.
- To evaluate the effectiveness of excision of the fractured hook and tendon repair.
Main Methods:
- Case series of four patients with flexor tendon ruptures due to hook of the hamate fractures.
- Surgical treatment included excision of the fractured hook and end-to-side tendon repair (profundus to profundus).
Main Results:
- All patients experienced pain relief and returned to preinjury activity levels post-surgery.
- Most patients had some limitation in range of motion in the repaired digit.
- Factors influencing range of motion included patient age and inflammation at the repair site.
Conclusions:
- Excision of the fractured hook and end-to-side tendon repair is a satisfactory treatment for flexor tendon ruptures.
- Postoperative range of motion is influenced by patient age and inflammation, not solely the repair technique.
