OBJECTIVE OF SURGERY: The cementless implantation of the surface replacement CapFlex-PIP enables pain relief, preservation of motion, improves lateral stability and corrects axis deviation in proximal interphalangeal (PIP) joints of patients with primary and secondary PIP osteoarthritis.
INDICATIONS: Painful PIP joints as a result of degenerative or posttraumatic osteoarthritis with restriction of motion. Secondary inflammatory destruction of PIP joints in rheumatoid arthritis with low inflammatory activity and good bone conditions.
CONTRAINDICATIONS: Destruction of PIP joints with severe bone loss, osseous defects and chronic joint luxation. Joint destruction induced by florid or subacute bacterial arthritis. Skin infections.
SURGICAL TECHNIQUE: Dorsal or palmar incision over the affected PIP joint while sparing the peritendinous tissue. Exposure of the proximal phalangeal head and meticulous bone resection. Precontouring of the bone bed for proximal prosthesis. Insertion of the trial prosthesis. Exposure of the distal base and resection in the correct axis. Determination of distal prosthesis size and height of the polyethylene inlay. Insertion of the trial prosthesis without bone protrusion. After clinical and radiological control, implantation of the final prosthesis.
FOLLOW-UP: Long finger splint, palmar flexor support splint for 2-3 weeks with active mobilization. Then active free mobilization with a twin bandage. After 6 weeks radiological check and free functional mobilization.
RESULTS: The active range of motion of 50 patients increased from 43.4° before surgery to 55.9° after 1 year with concomitant pain relief (6.5 to 2.2). In one case revision surgery was required due to traumatic rupture of the radial collateral ligament and four secondary tenolyses were performed.
