Arthrodesis of the first metatarsophalangeal joint (MTPJ) has been reported as gold standard for the treatment of advanced hallux rigidus and is a well-documented procedure. However, many patients demand a mobile MTPJ and therefore joint sparing procedures like MTPJ-arthroplasty have gained popularity. The aim of the present study was to present first mid-term results after hemiarthroplasty to treat advanced osteoarthritis of the first MTPJ. Between April 2006 and October 2013, a total of 81 hemiprostheses (AnaToemic®, Arthrex) in 71 consecutive patients (44 females, 27 male, 10 bilateral; mean age, 58 [range, 45–82]) were implanted at the St. Vincent Hospital Vienna (Austria). The indication for surgery was persistent MTPJ pain after failed conservative treatment combined with radiologic evidence of osteoarthritis (advanced hallux rigidus grade II-IV). Patients were clinically examined using the
Background. Total ankle arthrpoplasty (TAA) was performed frequently for ankle deformity caused by rheumatoid arthritis (RA) and osteoarthritis (OA). TAA has some advantages over ankle arthrodesis in range of motion (ROM). However, loosening and sinking of implant have been reported with several prostheses, especially constrained designs. Recently, we have performed mobile bearing TAA and report short term results of this prosthesis followed average 3 years. Method. 20 total ankle prostheses were implanted in patients with RA (n=14) or OA (n=6) in 19 patients (5 male and 14 female, one bilateral), between 2005 and 2009. We used FINE total ankle arthroplasty that is mobile bearing system (Nakashima Medical Co., Ltd, Okayama, Japan). All patients were assessed for
