Proximal Phalanx Hemiarthroplasty for the Treatment of Advanced Hallux Rigidus

Distraction Osteogenesis and Fusion for Failed First Metatarsophalangeal Joint Replacement: Case Series

“…10 In 1952, first MTP arthroplasty emerged as a new treatment option for end-stage hallux rigidus. 3,6 First MTP arthroplasty involves prosthetic replacement of the first MTP joint with either a unipolar or bipolar implant and has the potential to improve joint motion and reduce pain. 3 However, arthroplasty involves additional risks, including malposition, implant fracture, stress fracture, arthrofibrosis, and synovitis, all of which can lead to failure.…”

“…2 Delman et al also reported that arthroplasty procedures to treat hallux rigidus would fail, opining that the compressive and shear stresses placed on the implant surfaces put them at high risk of loosening. 3 Furthermore, unlike the knee and hip, there is little surface area available to establish a strong bone-implant interface. This, combined with higher stresses, particularly during walking and stair-climbing, leads to higher failure rates.…”
