Summary
The CapFlex-PIP implant effectively relieves pain and improves motion in proximal interphalangeal (PIP) joints affected by osteoarthritis. This surface replacement surgery offers significant functional gains for patients with PIP joint degeneration.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Rheumatology
Background:
- Osteoarthritis commonly affects proximal interphalangeal (PIP) joints, leading to pain and restricted motion.
- Current treatments may not fully restore function or alleviate pain in advanced PIP joint osteoarthritis.
- Surface replacement arthroplasty offers a potential solution for joint preservation and functional restoration.
Purpose of the Study:
- To evaluate the efficacy of cementless CapFlex-PIP surface replacement in treating primary and secondary PIP joint osteoarthritis.
- To assess pain relief, range of motion, lateral stability, and axis correction following CapFlex-PIP implantation.
- To determine the functional outcomes and complication rates associated with this arthroplasty technique.
Main Methods:
- Prospective study involving 50 patients with primary or secondary PIP joint osteoarthritis.
- Surgical technique involved cementless implantation of the CapFlex-PIP prosthesis via dorsal or palmar approach.
- Postoperative management included splinting, active mobilization, and radiological assessment.
Main Results:
- Significant improvement in active range of motion from 43.4° preoperatively to 55.9° at 1-year follow-up.
- Substantial reduction in pain scores from 6.5 to 2.2 postoperatively.
- One case required revision surgery for ligament rupture; four patients underwent tenolysis for secondary adhesions.
Conclusions:
- Cementless CapFlex-PIP surface replacement is an effective treatment for PIP joint osteoarthritis, providing pain relief and improved function.
- The procedure demonstrates good outcomes in terms of motion, stability, and axis correction.
- While generally safe, potential complications such as ligament rupture and tenolysis should be considered.
