In general the life expectancy of population is improving. This is causing to increase case load of peri-prosthesis fractures after joint replacements. We present our results of peri-prosthesis fracture around hip managed by revision arthroplasty. A retrospective analysis of 24 consecutive patients of periprosthetic hip fracture treated with a revision arthroplasty at Major Trauma Centre between February 2021 and January 2022.Abstract
Introduction
Methods
Most western countries have implemented fast-track hip fracture aiming at surgery within 24 hours, since the mortality rate hereafter rises markedly. In Greenland, it is not achievable to operate within 24 hours. Arctic people live in sparsely populated areas and Greenland's population is scattered along the vast coastline. All patients must be chartered to Nuuk by airplane which can take up till several days to weeks, due to logistics and the Arctic weather. This presents a challenge regarding adhering to western guidelines. The operative delay may be acceptable though, as it is the impression that the Greenlandic population survives and endures better than patients of western populations. However, as data are lacking, we aimed to describe mortality among hip fracture patients in Greenland taking frailty and comorbidities into account. All patients with ICD-10 codes DS720, DS721 and DS722 from 2018-2022 were identified as 261 patients diagnosed with hip fractures. Variables including time of diagnosis, time to operation, reasons for delay, ASA-score, Charlson Comorbidity index, time of death, and other possible confounding variables were analyzed. Primary outcome was mortality rates at 30-day post-OP and 1-year post-OP.Introduction
Method
Hip fractures represent one of the most challenging injuries in orthopaedic practice due to the associated morbidity, mortality and the financial burden they impose on the health care systems. By many still considered as the gold standard in the management of intertrochanteric fractures, the Dynamic Hip Screw utilizes controlled collapse during weight bearing to stabilize the fracture. Despite being a highly successful device, mechanical failure rate is not uncommon. The most accepted intraoperative indicator for lag screw failure is the tip apex distance (TAD), yet lateral femoral wall thickness (LWT) is another evolving parameter for detecting the potential for lateral wall fracture with subsequent medialization and implant failure. The aim of this study is to determine the mean and cut off levels for LWT that warrant lateral wall fracture and the implications of that on implant failure, revision rates and implant choice. This prospective cohort study included 42 patients with a mean age of 70.43y with intertrochanteric hip fractures treated with DHS fixation by the same consultant surgeon from April 2019 to December 2019. The study sample was calculated based on a confidence level of 90% and margin of error of 5%. Fracture types included in the study are 31A1 and 31A2 based on the AO/OTA classification system. LWT was assessed in all patients preoperatively using Surgimap (Nemaris, NY, USA) software. Patients were divided into two groups according to the post-operative integrity of the lateral femoral wall, where group (A) sustained a lateral femoral wall fracture intraoperatively or within 12 months after the index procedure, while in group (B) the lateral femoral wall remained intact. All patients were regularly followed up radiologically and clinically per the Harris Hip Score (HHS) for a period of 12 months.Introduction and Objective
Materials and Methods
Background Hip fractures are one of the leading causes of hospital admissions. Surgical treatment is often associated with significant blood loss, requiring post-operative erythrocyte transfusion. Aim To assess post-operative erythrocyte transfusion rates for hip fractures and evaluate the effect of tranexamic acid (TXA). All patients undergoing surgical repair of a hip fracture at RLBUHT between 1st April 2013 – 30th April 2014 were selected. Data regarding transfusion status and peri-operative TXA use was collected from electronic databases and case notes. 450 patients were admitted with a hip fracture, of whom 441 underwent surgery. Modalities of hip fixation included total hip replacement (THR, n=39), hemiarthroplasty (n=145), dynamic hip screw (DHS, n=116), cannulated hip screw (CHS, n=17) and long (n=71) and short (n=53) intramedullary hip screw (IMHS). 44.2% received a post-operative erythrocyte transfusion, with an average of 2.5 units per patient (range 1–9 units). With all study subjects included, the average transfusion rates for THR, hemiarthroplasty, DHS, CHS, long IMHS and short IMHS were 0.44 units, 0.78 units, 0.97 units, 0.47 units, 1.55 units and 1.19 units respectively. Data regarding intra-operative TXA administration was available for 318 (72.1%) patients, sixty-one of whom received TXA. 27.9% given TXA required a post-operative transfusion (range 0–6 units), compared to 35.4% of patient with no intra-operative TXA (range 0–11 units), p=0.142.Method
Results
Fractures of the femoral neck occurring outside the capsule of the hip joint are assumed to have an intact blood supply and hence their conventional management is by fixation rather than arthroplasty. The dynamic hip screw and its variants have been used over many years to fix such fractures but have inherent vulnerabilities; they require an intact lateral femoral cortex, confer a relatively long moment arm to the redistribution of body weight and may cause a stress riser due to the plate with which they are fixed to the femur. Intramedullary devices for fixation of proximal femoral fractures have a shorter moment arm, can be distally locked with reduced perforation of the femoral cortex and are believed to be inherently more stable. For these reasons, a number of surgeons believe them to be superior to the DHS for all extracapsular fractures and their use is now widespread. In this study, we present the usage trends of both devices in extracapsular fractures over the last five years and set these results in the context of patient demographics. Our departmental electronic patient management system was used to identify all patients undergoing surgery coded as either DHS or its variants or intramedullary fixation of hip fracture. The patients’ age, sex and American Society of Anaesthesiologists grading were recorded. Comparison between groups was made using appropriate tests in SPSS.Background
Methods
Up to 19% of patients who undergo surgery for an acute hip fracture are readmitted to the hospital within three months of the index operation. We aimed to identify risk factors for unplanned clinic attendance, readmission, and mortality within the first 12 months postoperatively and subsequently determine if there is a role for routine follow-up. Patients greater than 65 years old who underwent hip hemiarthroplasty using an uncemented Thompson implant for treatment of a traumatic non-pathological hip fracture were identified from a prospectively maintained database at a single institution between August 2007 and February 2011. Patient demographics, comorbidities, place of residence, mobility status, unplanned attendance to an orthopaedic clinic with symptoms relating to the respective limb, readmission, and mortality were recorded.Abstract

Methods
The Targon FN plate is a combination of the sliding hip screw and multiple cancellous screws. It is used in the fixation of intracapsular fractures of the neck of femur. The aim of this prospective audit was to assess clinical and radiological outcomes of Targon FN. All patients who had a Targon FN fixation over a period of 18 months at a district general hospital were included. A pro forma was completed using medical records, including x-ray images.Background
Method
Despite recent national advances in the care for the hip fracture patient, significant morbidity and mortality persists. Some of this morbidity is attributable to the analgesia provided in the hospital setting. The National Institute of Clinical Excellence recommends the use of simple oral analgesia including opioids, with fascia-iliac blocks used as an adjunct. Literature review reveals a paucity of evidence on this topic. The aim of this study was to evaluate the efficacy of fascia iliac blocks through analysis of pre and post-operative opioid usage, post-operative delirium, time to bowel opening and naloxone use. A retrospective study was performed between September-December 2013. Inclusion criteria were determined. 41 patients who received spinal anaesthesia alone and 41 patients who received spinal anaesthesia and a fascia-iliac block were included.Introduction
Methods
Since 1996, the Scottish Hip Fracture Audit (SHFA) group have published reports on the outcomes of patients with hip fractures. In the 2008 report, the group outlined the target standard that “98% of medically fit patients who have sustained a hip fracture should be operated on within 24 hours of ‘safe operating time’ (i.e. between 8 am and 8pm, seven days a week).”1. We aim to investigate the compliance of our unit to the SHFA target standard.BACKGROUND
AIM
Exeter Trauma Stem (ETS) is one of the most common implants used for treating displaced intracapsular hip fractures in the UK. We previously performed a radiographic audit of these implants which showed good placement was difficult. This was in particular relation to leg length discrepancy (LLD). This study reviewed the clinical outcomes of these patients, in particular looking at the relation of leg length discrepancy to outcome. We performed a clinical review of patients at 3 months and 1 year post ETS for hip fracture. Oxford hip score (OHS), Trendelenberg test, Visual Analogue Score (VAS) and walking aids required were recorded. Leg length discrepancy was determined radiographically on initial post op X-ray. This was recorded as Even (+/− 5mm), 6-10mm Long and >10mm long. Seventy-two patients were reviewed at 3 months and 21 at 1 year. Mean VAS was 1.6. At 3 months 66% were Trendelenberg positive. Of those Trendelenberg positive at 3 months only 42% remained positive at 1 year. Mean OHS at 3months and 1 year was 30.8 and 32.1 respectively. On radiographic review 38 implants were Even, 24 were 6-10mm Long and 10 implants were >10mm Long. There was no correlation between leg length discrepancy and either VAS or Trendelenberg test. 45 patients ambulated independently pre-op. Of these only 8 ambulated independently post-op, 18 used a stick and 11 a Zimmer frame. There was no correlation between post operative leg length discrepancy and either Visual Analogue Score, OHS or Trendelenberg test. Mean pain score was very low. There was however almost 10% of patients with a VAS greater than 6. 80% of patients dropped one ambulatory level post-op, this is consistent with previous studies. The ETS provides good pain relief with a low complication rate in the vast majority of patients.
Late infection is the most frequent complications after hemiarthroplasty. Urinary tract infections are the only distant septic focus considered to be a risk factor in the literature. We retrospectively reviewed 460 patients with hip fracture treated by hemiarthroplasy over a period of one year. Preoperative positive urine dipsticks and urine analysis have been looked at as causes for delay of surgery in absence of clinical manifestations of urinary tract infection. 367 patients were operated within 24 hours. 78 patients were delayed more than 78 hours. Urinary tract infection had the least contribution as a cause of delay. 99 patients had preoperative urinary tract infection and 57 patients had postoperative wound infection. Of these with postoperative surgical site infection, 31 patients did not show any evidence of preoperative urinary tract infection, 23 patients had preoperative urinary tract infection, two had leg ulcer and one had chest infection. 13 patients had chronic urinary tract infection and five patients had the same causative organism in urine & wound. The most common organisms of urinary infection are E. Coli, mixed growth, Enteroccocus Faecalis, Pseudomonas and others. The most causative organism of the postoperative surgical site infection are Staph aureus including MRSA, mixed growth including Staph. Epidermidis, Enteroccocus Faecalis and others There is no direct significant correlation between preoperative urinary tract infection and surgical site infection. We recommend that preoperative urinary tract infection should be treated as a matter of urgency but it should not delay hip fracture surgery unless it is causing symptoms.
