Summary
Complex dorsal metacarpophalangeal joint dislocation (MPJD) often results in satisfactory long-term hand function. Even with complications, early open reduction treatment leads to good outcomes for patients with MPJD.
Area of Science:
- Orthopedic surgery
- Hand surgery
- Traumatology
Background:
- Complex dorsal metacarpophalangeal joint dislocation (MPJD) is a significant hand injury.
- Understanding long-term outcomes and potential complications is crucial for effective management.
Purpose of the Study:
- To evaluate the long-term functional results of complex dorsal MPJD.
- To determine if functional deficits occur despite common complications.
Main Methods:
- A case series of 5 patients with complex dorsal MPJD was followed for a median of 13 years.
- A comprehensive literature review on follow-up and complications was conducted.
- Study design: Prognostic V.
Main Results:
- All patients reported full hand function; 2 had mild loss of MPJ flexion and grip strength.
- Mean QuickDASH score was 4.5; 2 patients developed secondary osteoarthritis after fracture fixation.
- Literature highlights complications like stiffness, arthritis, and osteonecrosis due to diagnostic delays or improper treatment.
Conclusions:
- Early open reduction for complex dorsal MPJD yields satisfactory outcomes.
- Effective treatment on the day of injury can mitigate long-term functional deficits, even with complications.
