“…As more and more hard-on-hard articulations are used in modern THA, the femoral head may more often obscure part of the cup rim so drawing the entire ellipse on a radiograph becomes difficult. Because PACS workstations are now available in most hospitals, radiography has moved from hard-copy film to digital techniques and electronic tools can be used reliably for the evaluation of hip arthroplasty [22], making it simple to draw the entire ellipse using electronic tools [20]. The interteardrop line affects the measurement of radiographic inclination.…”

Association between changes in global femoral offset after total hip arthroplasty and function, quality of life, and abductor muscle strength

et al. 2015

Background and purposeThere is no consensus on the association between global femoral offset (FO) and outcome after total hip arthroplasty (THA). We assessed the association between FO and patients’ reported hip function, quality of life, and abductor muscle strength.Patients and methodsWe included 250 patients with unilateral hip osteoarthritis who underwent a THA. Before the operation, the patient’s reported hip function was evaluated with the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index and quality of life was evaluated with EQ-5D. At 1-year follow-up, the same scores and also hip abductor muscle strength were measured. 222 patients were available for follow-up. These patients were divided into 3 groups according to the postoperative global FO of the operated hip compared to the contralateral hip, as measured on plain radiographs: the decreased FO group (more than 5 mm reduction), the restored FO group (within 5 mm restoration), and the increased FO group (more than 5 mm increment).ResultsAll 3 groups improved (p < 0.001). The crude results showed that the decreased FO group had a worse WOMAC index, less abductor muscle strength, and more use of walking aids. When we adjusted these results with possible confounding factors, only global FO reduction was statistically significantly associated with reduced abductor muscle strength. The incidence of residual hip pain and analgesics use was similar in the 3 groups.InterpretationA reduction in global FO of more than 5 mm after THA appears to have a negative association with abductor muscle strength of the operated hip, and should therefore be avoided.

“…Standard anteroposterior (AP) and lateral radiographs of the pelvis were made for all patients immediately after the operation, at six and 12 months, and annually thereafter. LLD was radiologically measured (EGR) on the anteroposterior view according to the method of Patel et al 15 as the distance between the tip of the lesser trochanter and the teardrop. We recorded the pre-operative and postoperative positions of the acetabular component by assessing the abduction angle of the component, and the height and horizontal location of the centre of the hip.…”

A total of 31 patients, (20 women, 11 men; mean age 62.5 years old; 23 to 81), who underwent conversion of a Girdlestone resection-arthroplasty (RA) to a total hip replacement (THR) were compared with 93 patients, (60 women, 33 men; mean age 63.4 years old; 20 to 89), who had revision THR surgery for aseptic loosening in a retrospective matched case-control study. Age, gender and the extent of the pre-operative bone defect were similar in all patients. Mean follow-up was 9.3 years (5 to 18). Pre-operative function and range of movement were better in the control group (p = 0.01 and 0.003, respectively) and pre-operative leg length discrepancy (LLD) was greater in the RA group (p < 0.001). The post-operative clinical outcome was similar in both groups except for mean post-operative LLD, which was greater in the study group (p = 0.003). There was a significant interaction effect for LLD in the study group (p < 0.001). A two-way analysis of variance showed that clinical outcome depended on patient age (patients older than 70 years old had worse pre-operative pain, p = 0.017) or bone defect (patients with a large acetabular bone defect had higher LLD, p = 0.006, worse post-operative function p = 0.009 and range of movement, p = 0.005), irrespective of the group. Despite major acetabular and femoral bone defects requiring complex surgical reconstruction techniques, THR after RA shows a clinical outcome similar to those obtained in aseptic revision surgery for hips with similar sized bone defects.
