‘Lange termijn uitkomst na hallux rigidus ingreep middels Cheilectomie, Keller’s arthroplasty of Artrodese’

Despite the extensive literature on the surgical treatment of HR, no studies with a follow up exceeding 10 years are available. Pain might be one of the main reasons to treat the first ray in patients with HR, but in the long-term creating a permanent satisfactory correction resulting in a restoration of the weight bearing function of the first ray is indispensable. Therefore, this study will be conducted to assess patient satisfactory, clinical and subjective patient reported outcome and plantar pressure after surgical treatment for HR.

We hypothesize that, in line with the results of the previous study, cheilectomy and Keller’s arthroplasty show better clinical and subjective outcome in patients treated for low grade HR compared to arthrodesis. In addition, we hypothesize that clinical and subjective outcomes are comparable for high grade HR treated with Keller’s arthroplasty or arthrodesis after >17 years of FU. Concerning plantar pressure, we expect that cheilectomy restores the weightbearing function of the first ray, while a shift of load to the lesser metatarsals will be observed in the arthrodesis and Keller’s arthroplasty group. Concerning recurrence rate, we expect a high recurrence rate in cheilectomy patients compared to Keller’s arthroplasty patients, while fusion is achieved in >90% of the arthrodesis patients.

+/- 17 year postoperative

Ninety four feet in 77 patients were included in the primary study and were treated with a cheilectomy (n=32), a Keller’s arthroplasty (n=28) and arthrodesis (n=34).
