3 preop postop Short Term Results are Good Easley et al (1999): 57 patients, minimum 3-year follow-up AOFAS score improved from 45 to 85 90% satisfaction Dorsiflexion improved ~ 20 degrees Progression of grade of HR on xrays in >50% with time! Easley ME et al, FAI 20(3) 1999 Good But Not a Normal Joint Dorsal cheilectomy is effective in: Re-establishing symmetrical plantar pressure loading Increasing 1 st MTP dorsiflexion and abduction But resting posture is not normal with an average equinus posture of 10 0 May explain accelerated djd Nawoczenskiet al.

5 Options For Grade III HR 1. Cheilectomy + osteotomy 2. Interposition arthroplasty i. Soft tissue allograft ii. Soft tissue autograft iii. Prosthetic vinyl implant 3. Arthrodesis Cheilectomy + Periarticular Osteotomies O Malley et al (2013): 81 patients with Grade III HR Cheilectomy + proximal phalangeal extension osteotomy ( Moberg) O Malley et al JBJS 95(7), 2013 Cheilectomy + Moberg Mean f/u of 4.3 years Sig increased DF: to No progressive IP arthritis on x-ray 85% satisfied 5% went onto an arthrodesis O Malley et al JBJS 95(7),
