Hallux rigidus is the most common arthritic condition of the foot. Interpositional arthroplasty (IPA) is indicated for advanced-stage hallux rigidus and attempts to maintain joint motion through insertion of a biologic spacer into the joint.

6 天之前 · Interpositional arthroplasty remains a viable contender to reduce pain in the joint while maintaining the motion. ... The mechanical advantage of this known foot and ankle evertor could potentiate lateral foot and ankle pathology, increase the mechanical advantage of the posterior tibial tendon and as a result, increase the likelihood of ...

2019年4月2日 · Interposition arthroplasty appears to be a viable option for the treatment of moderate to severe hallux rigidus in patients looking to salvage motion through the first metatarsophalangeal joint.

2017年5月27日 · Capsular Interpositional Arthroplasty Hallux rigidus refers to degenerative arthritis of the first metatarsophalangeal (MTP) joint that is characterized by pain, decreased range of motion (ROM), and proliferative osteophyte formation.

Interposition arthroplasty was historically a modification of simple resection arthroplasty of a joint. The addition of a local tissue or skin to prevent painful contact between the ends of the resection evolved into a strategy of creating a biological membrane over an arthritic joint surface that might otherwise be considered for prosthetic ...

The ultimate means of functional restoration of joints with end stage arthritis is prosthetic replacement. Even though there is reluctance to replace the joint of a younger individual, the mean age of joint replacement continues to decrease.

This technical note describes the arthroscopic approach of interpositional arthroplasty of the second metatarsophalangeal joint using the extensor digitorum brevis tendon. It is indicated in adult patients with extensive involvement of the metatarsal head cartilage, especially when cartilage degeneration of the proximal phalanx is also present.

2023年11月8日 · Interpositional arthroplasty for the treatment of hallux rigidus (HR) involves resection of the diseased joint surface and placement of spacer material within the joint to preserve length at the metatarsophalangeal joint while still allowing for range of motion.
