To evaluate the normal range of motion of the cervical spine, 70 healthy subjects were studied using radiography and clinical examination. An equal number of men and women were studied; age ranged from 12 to 79 years. Radiographs were taken in the lateral projection during maximal flexion and extension. In the frontal projection, radiographs were taken(More)
BACKGROUND A high quality decision requires that patients who meet clinical criteria for surgery are informed about the options (including non-surgical alternatives) and receive treatments that match their goals. The aim of this study was to evaluate the psychometric properties and clinical sensibility of a patient self report instrument, to measure the(More)
BACKGROUND There is currently a paucity of devices available for continuous, long-term monitoring of human joint motion. Non-invasive, inexpensive devices capable of recording human activity and joint motion have many applications for medical research. Such a device could be used to quantify range of motion outside the gait laboratory. The purpose of this(More)

Kaplan-Meier survival analysis was used to calculate survival probabilities with 95% confidence interval (CI). Cox(More)
The Swedish Total Hip Replacement Registry began in 1979 to describe the outcome of primary hip replacements and to provide information regarding serious complications. The importance of the register and the continual quality improvement over the long-term has been well documented (Herberts et al, 1989; Herberts et Malchau, 1997; Malchau et al, 1993). The(More)
Due to the uneven and often inadequate quality of cross-table lateral hip radiographs, many radiographic studies of femoral head penetration into polyethylene in total hip arthroplasty are limited to the two-dimensional measurement of femoral head penetration using the A/P film only. We postulated that the use of two oblique frontal projections at 90(More)
BACKGROUND AND PURPOSE Rehabilitation of patients with transfemoral amputations is particularly difficult due to problems in using standard socket prostheses. We wanted to assess long-term fixation of the osseointegrated implant system (OPRA) using radiostereometric analysis (RSA) and periprosthetic bone remodeling. METHODS 51 patients with transfemoral(More)
BACKGROUND AND PURPOSE Traditions are passed on from experienced surgeons to younger fellows and become "the right way to do it". Traditions associated with arthroplasty surgery may, however, not be evidence-based and may be potentially deleterious to both patients and society, increasing morbidity and mortality, slowing early functional recovery, and(More)
