Background
The proximal interphalangeal (PIP) joint plays an important role in both grasp and pinch. In terms of mobility and stability, an intact PIP joint plays an important role in isolated finger function as well as the function of the entire hand. Currently, there are only a few surgical management protocols: arthrodesis, arthroplasty without joint replacement and arthroplasty with prosthetic replacement. This study aims to evaluate the gap arthroplasty technique as an alternative method for PIP joint reconstruction and to identify its advantages and disadvantages.
Methods
This interventional prospective study was conducted in a university hospital setting. We performed PIP joint gap arthroplasty using a dynamic traction device system after resection of the ankylotic area. The assessed outcome parameters were pain relief and range of motion (ROM) at 6 months, post-operatively.
Results
The results showed a complete pain relief, excellent passive ROM (in mean 65°) and a good active ROM (in mean 41°). This allows the patient to move the four ulnar fingers together without interruption from the injured finger. Overall patient satisfaction was very good.
Conclusions
Gap arthroplasty is an easy and effective technique for the PIP joint, and it does not require expensive materials as do artificial joint procedures. However, further studies are needed to conduct a long-term functional evaluation.
Level of Evidence: Level IV, therapeutic study.
