The aim of this study was to analyze and compare clinical, radiological and mortality outcomes of patients who underwent cemented hip hemiarthroplasty for displaced neck of femur fractures using a SPAIRE technique when compared to a pair-matched control cohort who underwent the same procedure using the direct lateral approach.

A retrospective review of patients who underwent cemented hip hemiarthroplasty for displaced neck of femur fractures by a single surgeon using a SPAIRE technique over a two-year period between July 2019 and July 2021 was performed. These were subsequently pair matched in a 5:1 ratio for age, gender, ASA grade and residential status with a control group who underwent cemented hip hemiarthroplasty by 4 other surgeons using a direct lateral approach

The study included a total of 240 patients (40 and 200 pairmatched to SPAIRE and control groups respectively), with a mean age of 81.0 ± 8.2 years (63–99) and a mean follow-up of 12 ± 3 months (3–30). Overall, there was no significant difference in any of the radiological or mortality outcome scores assessed between the SPAIRE and control groups (p > 0.05 for all). There was a significantly lower number of patients in the SPAIRE group who dropped a level of mobility from their pre-injury baseline at 30-days post-operatively (8.1% versus 31.6%; p = 0.003). However, this appeared to have resolved at 120-day follow-up with no significant differences between the groups in terms of those acquiring a new baseline mobility at 120-days post-operatively (2.7% versus 13.2%, p = 0.09).

In cases of cemented hip hemiarthroplasty for displaced intracapsular neck of femur fractures, the SPAIRE technique appears to offer patients an earlier return to levels of baseline pre-injury mobility when compared to a direct lateral approach.

Introduction

Post-operative gait abnormalities are recognized following total hip arthroplasty (THA). Despite global improvement in functional outcome, gait abnormality persists for a decade or more. In this study 3-dimensional gait analysis (3DGA) was performed using a portable system with Inertial Measurement Units (IMUs) to quantify this abnormality.

Methods

The gait of 55 patients with monarthrodial hip arthrosis was measured pre-operatively and at one year post-surgery. Patients with medical co-morbidity or other conditions affecting their gait were excluded. Six IMUs were aligned at the level of the anterior superior iliac spines, mid-thigh and mid-leg. Data was analysed using proprietary software. Each patient underwent a conventional THA using a posterolateral approach. 92 healthy individuals were assessed for comparison.

The in-cement technique for revision hip arthroplasty involves retaining the original cement-bone interface. This has been proven to be a biomechanically stronger method than recementing after complete removal of the original cement mantle.

This study reviewed a series of 54 consecutive revision hip arthroplasty procedures, using the in-cement technique, between November 1999 and November 2003. Clinical and radiological follow-up included functional assessment.

There were 54 procedures performed in 51 patients, whose mean age at surgery was 70.3 years (45 to 85). A total of 42 were available at a mean follow-up of 29.2 months (6 to 51). There was no radiological evidence of loosening. Functional assessments were available for 40 patients who had a mean Harris hip score of 85.2 (51.9 to 98.5), a mean Oxford hip score of 19.6 (12 to 41), a mean UCLA activity profile score of 5.9 (3 to 8) and a mean SF-36 score of 78.0 (31.6 to 100).

The in-cement technique provides consistent, high functional outcomes and should be considered in appropriately selected cases.
