“…Whilst the range of movement imparted by the implant is far less than normal, any mobility of the great toe increases flexion strength during take‐off facilitating a more normal gait pattern. These clinical results and implant survival of 94.4% compare favourably with other series of shorter follow‐up [6–10] and may exceed those of shoulder [16], ankle [17] and elbow [18] arthroplasty. Despite these reports, scepticism remains due to problems relating to the abrasion and fatigue of the implant and the subsequent host response to wear debris [19].…”

“…To overcome these problems, a double‐stemmed flexible hinged arthroplasty was developed constructed of High Performance Silicone Elastomer [5]. Whilst good clinical results have been reported in the medium term [6–10], concerns remain about the durability of the implant, silicone synovitis, osteolysis, shortening of the hallux and metatarsalgia [11, 12]. This retrospective study was therefore performed to evaluate the clinical and radiological outcomes of Swanson double‐stem silastic first MTPJ arthroplasty.…”

“…Self-assessment by the patient observing the gait patterns in a mirror (even at home) combined with daily foot gymnastics will normalize the plantigrade and prevent pain. On the Shankar [17] and Kitaoka scores [18] patients who did not undertake activity of their own to relieve forefoot pain were assessed as having moderate to poor outcomes. The average active ROM did not change substantially from September 2000 to the follow-up in September/October 2005.…”

Background: Hemi-and total-replacement of the first metatarsophalangeal joint (MTP1) remains controversial due to failures observed in earlier decades. The TOEFIT-PLUS TM system was developed in part to address these earlier failures, but published reports investigating its use have been limited.Materials: The TOEFIT-PLUS TM MTP1 joint replacement system is designed with a self-tapping thread on a conical titanium core that provides cement-free, primary stable anchorage and focal pressure reduction in the corticocancellous bone due to an enlarged surface area. The modular design allows surgeons to decide intraoperatively whether to proceed with hemi-or total arthroplasty. Data from 3 studies are presented: 64 patients receiving total prostheses and followed-up annually (Seeber); 12 hemi-prostheses in 10 patients with 5.1 years average follow-up and 6 total prostheses in 5 patients with 1.5 years average follow-up (Knessl); and 54 prostheses (14 hemi-prostheses, 40 total prostheses) in 52 patients followed-up for an average of 3 years (multicenter study).Results: Seeber reported a 42.7-month service life of the prosthesis at the time of follow-up. Five patients (6.8%) were reoperated. Passive hallux motion was 15-18g reater than active motion, and patient satisfaction at follow-up was high. Knessl reported an average range of motion (ROM) in the sagittal plane of 55˚with an average dorsal extension of 25.3˚and plantar flexion of 30˚in patients who received hemi-prostheses. Prosthesis removal was necessary in 3 patients. Prosthesis loosening has not been observed. In patients undergoing total arthroplasty, ROM was recorded at 58˚. A revision operation was necessary in 1 patient. Revision surgery was necessary in 11 patients (21.1%) in the multicenter study. Patient-reported outcomes were favorable.Conclusion: The TOEFIT-PLUS TM joint replacement system offers improved implant stability and is able to handle high biomechanical loads and neutralize shear forces. When compared with other systems, it is associated with reduced osseointegration problems. Intensive postoperative strategies are recommended. Long-term follow-up studies are needed to further investigate the utility of this system.
