OBJECTIVE To compare the functional outcome of patients with and without arthrosis, and to determine whether the development of arthrosis is related to the distance of the tumor from the subchondral bone. METHODS Forty six patients treated for Giant-cell tumor (GCT) between 1975 and 1999 met inclusion criteria. GCT was diagnosed by percutaneous biopsy and confirmed after resection, in all cas...

Arthrosis following rupture of the anterior cruciate ligament has been analysed in two series. The first series was derived from a review of 150 cases of reconstruction of the anterior cruciate ligament with a follow-up of 3 years or more. Arthrosis was seen to have developed in 13.3%. The second series was concerned with 64 cases of unilateral arthrosis treated by upper tibial valgus osteotomy...

Mechanoreceptors have been extensively studied in different joints and distinct signals that convey proprioceptive information to the cortex. Several clinical reports have established a link between the number of mechanoreceptors and a deficient proprioceptive system; however, little or no literature suggest concentration of mechanoreceptors might be affected by hip arthrosis. The purpose of th...

Bone density may influence the primary fixation of cementless implants, and poor bone density may increase the risk of implant failure. Before deciding on using total joint replacement as treatment in osteoarthritis of the trapeziometacarpal joint, it is valuable to determine the trapezium bone density. The aim of this study was to: (1) determine the correlation between measurements of bone min...

Adverse reactions to metal-on-metal (MoM) prostheses are well known from total hip joint resurfacing arthroplasty with elevated serum chrome or cobalt, pain and pseudo tumor formation. It may, however, also be seen after total joint replacement of the trapeziometacarpal joint using MoM articulation, and we present two cases of failure of MoM prostheses due to elevated metal-serum levels in one ...

Despite the obvious success of arthroplasty trapeziectomy with or without interposition and prosthesis--in the treatment for trapeziometacarpal osteoarthritis, one may question the value of an arthrodesis in particular situations. In most reported series the outcome is reasonably successful, but when comparing the results of arthrodesis with arthroplasty, there is convincing evidence that the l...

Pes cavovarus affects the ankle biomechanics and may lead to ankle arthrosis. Quantitative T2 STAR (T2*) magnetic resonance (MR) mapping allows high resolution of thin cartilage layers and quantitative grading of cartilage degeneration. Detection of ankle arthrosis using T2* mapping in cavovarus feet was evaluated. Eleven cavovarus patients with symptomatic ankle arthrosis (13 feet, mean age 55...

PURPOSE To review the subjective and functional results of basal thumb metacarpal osteotomy for the treatment of trapeziometacarpal osteoarthritis. METHODS Between July 1993 and November 1998, 35 thumb osteotomies without internal fixation were performed on 33 patients in the Christchurch Hospital, New Zealand. Records of 28 thumbs (13 right and 15 left) of 26 patients (17 women and 9 men) we...

BACKGROUND More then half of elderly adults over 60 years old suffer from arthrosis. Pain and mobility reduction associated with this disease, reduce elderly peoples independence and are the reason of their physical disability. The aim of this study was to estimate coincidence of arthrosis and depression in population of outpatients of Geriatric Clinic and to asses the influence of each disease...
