“…Hip function was rated with the HHS [17,18,40], which ranges from 0 to 100 points covering a maximum of 44 points for absence of pain, 47 points for function, and 9 points for range of motion and absence of deformity. The primary outcome was the HHS after 12 months.…”

Hemiarthroplasty is the most commonly used treatment for displaced femoral neck fractures in the elderly. There is limited evidence in the literature of improved functional outcome with cemented implants, although serious cement-related complications have been reported. We performed a randomized, controlled trial in patients 70 years and older comparing a cemented implant (112 hips) with an uncemented, hydroxyapatite-coated implant (108 hips), both with a bipolar head. The mean Harris hip score showed equivalence between the groups, with 70.9 in the cemented group and 72.1 in the uncemented group after 3 months (mean difference, 1.2) and 78.9 and 79.8 after 12 months (mean difference, 0.9). In the uncemented group, the mean duration of surgery was 12.4 minutes shorter and the mean intraoperative blood loss was 89 mL less. The Barthel Index and EQ-5D scores did not show any differences between the groups. The rates of complications and mortality were similar between groups. Both arthroplasties may be used with good results after displaced femoral neck fractures.

“…The patients underwent a clinical examination preoperatively and 3 and 12 months postoperatively, in which the Harris hip score [41], and a pain score using a NRS of 0 to 10 (0 = no pain, 10 = maximum pain) were recorded [43,44]. Trendelenburg sign was evaluated to test the function of the abductor muscles.…”

Evidence of Reduced Muscle Trauma Through a Minimally Invasive Anterolateral Approach by Means of MRI

et al. 2010

Background Minimally invasive techniques in THA are intended to minimize periarticular muscle trauma. The lateral approach has a risk of partial gluteal insufficiency, while the anterolateral approach carries the risk of damaging the tensor fasciae latae through intermuscular nerve and compression injury. Questions/purposes We assessed the surgical influence of the anterolateral minimally invasive approach and the modified direct lateral approach on the tensor fasciae latae and gluteus medius. Methods We prospectively randomized 44 patients with primary coxarthrosis to receive a cementless THA via the anterolateral minimally invasive approach or the modified direct lateral approach. We performed clinical and MRI examinations preoperatively and 3 and 12 months postoperatively, including Harris hip and pain scores. MRI analysis included assessment of the tensor fasciae latae and gluteus medius with regard to fatty atrophy and changes in the muscle cross-sectional area.Results Clinical scores were similar in the two groups but a low-grade Trendelenburg sign was observed more frequently in the lateral group. MRI showed a pronounced, postoperative fatty atrophy of the anterior part of the gluteus medius more often; and a compensatory hypertrophy of the tensor fasciae latae occurred. Higher-grade atrophy of the tensor fasciae latae and gluteus medius did not occur with the anterolateral approach. Conclusions We found no increased damage to the tensor fasciae latae with the anterolateral approach. The lateral approach was associated with increased partial gluteus atrophy and a compensatory hypertrophy of the tensor fasciae latae. Based on fewer structural changes in the musculature, we recommend the anterolateral minimally invasive approach.
