Acetabular labral tears and associated intra-articular
pathology of the hip have been recognised as a source of symptoms.
However, it is now appreciated that there is a relatively high prevalence
of asymptomatic labral tears. In this study, 70 young asymptomatic
adult volunteers with a mean age of 26 years (19 to 41) were recruited
and underwent three tesla non-arthrographic MR scans. There were
47 women (67.1%) and 23 men (32.9%). Labral tears were found in 27 volunteers (38.6%); these were
an isolated finding in 16 (22.9%) and were associated with other
intra-articular pathology in the remaining 11 (15.7%) volunteers.
Furthermore, five (7.1%) had intra-articular pathology without an
associated labral tear. Given the high prevalence of labral pathology in the asymptomatic
population, it is important to confirm that a patient's symptoms
are due to the demonstrated abnormalities when considering surgery. Cite this article:
One hundred and twenty-seven consecutive patients with displaced subcapital fractures of the femoral neck (Garden Grade III or IV) all under 80 years of age and independently mobile, were randomly allocated to fixation with either double divergent pins or a single sliding screw-plate device. The incidence of non-union and infection in the sliding screw-plate group was significantly higher, and we believe that when internal fixation is considered appropriate multiple pinning should be used. Mobility after treatment was disappointing in about half of the patients, and we feel that internal fixation can only be justified in patients who are physiologically well preserved and who maintain a high level of activity.
The management of displaced subcapital fracture of the hip is still controversial because of the high incidence of complications after internal fixation or hemiarthroplasty. To avoid some of these complications we have used primary total hip replacement for independently mobile patients over 65 years of age. A total of 163 cases, operated on over four years, have been reviewed. There were relatively more dislocations after operation for fracture than after total replacement for arthritis, and these were associated with a posterior approach to the hip. Only seven revision operations have been required. Of 57 patients who were interviewed an average of 42 months after replacement, 62% had excellent or good results as assessed by the Harris hip score. All the others had major systemic disease which affected their assessment. This inadequacy of current systems of hip assessment is discussed. It is concluded that total hip replacement is the best management for a selected group of patients with this injury, and that further prospective studies are indicated.
