Limb Length Inequality in Patients After Primary Total Hip Arthroplasty: Analysis of Radiological Assessment and Influencing Risk Factors Based on a District General Hospital Experience of 338 Cases

Introduction. Nasal and skin colonization by methicillin-resistant Staphylococcus aureus (MRSA) are linked to a higher incidence of infection after total joint replacement. The prevalence of colonization is poorly defined in Latin American countries. Aim. The aim of the present study was to determine the prevalence of MRSA colonization in the nostrils and groin using real-time polymerase chain reaction (RT-PCR) in patients undergoing total hip arthroplasty (THA). Methodology. In this cross-sectional study, 146 patients undergoing THA between December 2015 and March 2017 in a tertiary-care university-affiliated hospital in Chile were screened for MRSA colonization before the procedure using RT-PCR independently in the nostrils and groin. Risk factors for colonization were documented. Results. Seven of the 146 (5 %) patients undergoing THA were carriers of MRSA in the nostrils and/or the groin. Recent antibiotic use was identified as a risk factor for colonization, OR=4.86 [95 % confidence interval (CI): 1.56–13.96]. Patients reporting at least one of the seven surveyed risk factors had an OR of 2.39 (95 % CI: 0.37–25.77) for colonization. MRSA colonization frequency was twofold higher in the groin as opposed to the nostrils (P=0.014). Conclusion. Five percent of the patients undergoing THA were identified as carriers of MRSA. Recent antibiotic use is a relevant risk factor for MRSA colonization in patients undergoing primary total hip arthroplasty.

Limb Length Inequality

<p class="abstract">Correcting limb length inequality without compromising hip stability is one of the major intraoperative challenges in Total hip arthroplasty (THA) as it is a major cause of patient dissatisfaction and litigation against surgeon. Surgeons performing THA should aim to minimize Limb Length Discrepancy (LLD), and therefore should adopt a reliable method of doing so. Thus a reproducible technique which effectively reduces postoperative LLD without increasing operative time and is easy to apply is a need of time. Although various preoperative and intraoperative techniques are described in literature, none is universally applicable and is without limitations. We are presenting a review of 50 articles on limb length discrepancy after total hip arthroplasty, its implications and several techniques to avoid it. We suggest that every effort should be made to minimise postoperative Limb Length Discrepancy by combined use of preoperative and intraoperative techniques.</p>
