Distal interphalangeal hemiarthroplasty (ADIP): preliminary series of 14 cases
نویسنده
چکیده
Introduction The DIP Argo hemiprosthesis (ADIP) was designed in 2012 with the idea of replacing the destroyed / arthritic head of the middle phalanx (P2) and was implanted in 2013 for the first time.Basically the idea was to achieve coverage of P2 as opposed to P3 (distal phalanx), because the last phalanx of the digit is so thin, and the joint surface often so destroyed that the fixation of the distal part is deemed not feasible. The implant comprises part of thesurface of a cylinder that covers only the articular part of the middle phalanx, and is fixed to a stem 8mm long and very narrow, inserted into the medullary cavity.The stem is coated with Hydroxyapatite(HAP) and one size fits all.

ABSTRACT The English literature reports a mere handful of cases involving simultaneous dislocation of two joints in the same finger. To our knowledge, all cases reported to date have been in skeletally mature individuals. We report a case of simultaneous proximal interphalangeal (PIP) and distal interphalangeal (DIP) joints dislocations in one finger in a 14-year-old rugby player, managed by cl...
متن کاملDistal interphalangeal joint arthrodesis with Herbert screw
Fifteen patients underwent arthrodesis of finger distal interphalangeal joint (DIP) and/or thumb interphalangeal joint (IP). Only Herbert screw intramedullary compression fixation was used. There was one faulty proximal thread placement with some pain, but the patient refused further surgery. Full union was achieved in 14 of the cases, with prominent hardware in one and intolerance to cold in two.

Hallux rigidus (HR) is a progressive degenerative pathology affecting the first metatarsophalangeal joint. The aim of the present study is to report our experience on the treatment of HR patients with two different surgical methods: arthrodesis and hemiarthroplasty. Twelve patients (14 HR) underwent surgery for HR from July 2004 to October 2009. Median age was 58 years (Interquartile Range (IQR...
