title: Data from: Assessing leg length discrepancy post-total hip arthroplasty for neck of femur fractures: a retrospective analysis

description: Introduction: Limb length discrepancy (LLD) is a recognized concern
 following total hip arthroplasty (THA) for various hip pathologies. THA is
 a common surgical intervention aiming to alleviate pain and restore
 function. LLD impacts patient satisfaction and functional outcomes. The
 main aim of this study was to detect any LLD following THA for a fractured
 neck or femur, and to focus on the functional outcome of THA in terms of
 LLD. Methods: A retrospective study was conducted from January 2019 to
 December 2021, including all NOF patients eligible for THR based on
 mobility criteria and clinical assessment. Data were obtained from
 electronic patient records, postoperative notes, radiographs, and
 physiotherapy assessments. Results: There were 58 patients who underwent
 THA for NOF fractures, average age was 75.6 years (range 62-92 years). The
 majority (96%) of patients were classified as ASA 2. The time of surgery
 (TOS) averaged 38.6 hours (range 8-266 hours), with 19 cases experiencing
 delays of over 36 hours due to surgeon availability. In terms of limb
 length discrepancy, no patients reported or were documented to have LLD
 postoperatively. Measurements showed a vertical offset difference mean of
 0.47 cm (range 3.46-7.1 mm) and a horizontal offset difference mean of
 0.51 cm (range 3.34-6.89 mm) between the operated and normal sides.
 Conclusion: LLD post-THR in NOF patients did not appear clinically
 significant in this study's short-term follow-up. However,
 radiological evaluations revealed a notable disparity in leg lengths.
description: This retrospective study was conducted between January 2019 and
 December 2021. Data were collected by retrieving records of patients with
 neck of femur (NOF) fractures who underwent total hip arthroplasty (THA)
 for their fractures at the University Hospital of Derby and Burton NHS
 Foundation Trust. Demographic data, including age,
 gender, and relevant medical history, were collected. Implant types were
 noted from postoperative notes, physiotherapy records, and reviewed
 postoperative radiographs. Comorbidities were recorded using electronic
 patient records (EPR). Radiological assessments were
 conducted using standardized radiographs. Data were
 summarized using descriptive statistics. Quantitative data were presented
 as mean, standard deviation, median, minimum, and maximum values.
 Categorical data were summarized using frequency counts and relative
 frequencies (percentages). t-test was used to compare the means of the two
 groups.
