Aims. Periprosthetic fractures (PPFs) around the knee are challenging injuries. This study aims to describe the characteristics of knee PPFs and the impact of patient demographics, fracture types, and management modalities on in-hospital mortality. Methods. Using a multicentre study design, independent of registry data, we included adult patients sustaining a PPF around a knee arthroplasty between 1 January 2010 and 31 December 2019. Univariate, then multivariable, logistic regression analyses were performed to study the impact of patient, fracture, and treatment on mortality. Results. Out of a total of 1,667 patients in the PPF study database, 420 patients were included. The in-hospital mortality rate was 6.4%. Multivariable analyses suggested that American Society of Anesthesiologists (ASA) grade, history of peripheral vascular disease (PVD), history of rheumatic disease, fracture around a loose implant, and
Aims. The aim of this study was to identify the risk factors for adverse events following the surgical correction of cervical spinal deformities in adults. Methods. We identified adult patients who underwent corrective cervical spinal surgery between 1 January 2007 and 31 December 2015 from the MarketScan database. The baseline comorbidities and characteristics of the operation were recorded. Adverse events were defined as the development of a complication, an unanticipated deleterious postoperative event, or further surgery. Patients aged < 18 years and those with a previous history of tumour or trauma were excluded from the study. Results. A total of 13,549 adults in the database underwent primary corrective surgery for a cervical spinal deformity during the study period. A total of 3,785 (27.9%) had a complication within 90 days of the procedure, and 3,893 (28.7%) required further surgery within two years. In multivariate analysis, male sex (odds ratio (OR) 0.90 (95% confidence interval (CI) 0.8 to 0.9); p = 0.019) and a posterior approach (compared with a combined surgical approach, OR 0.66 (95% CI 0.5 to 0.8); p < 0.001) significantly decreased the risk of complications. Osteoporosis (OR 1.41 (95% CI 1.3 to 1.6); p < 0.001), dyspnoea (OR 1.48 (95% CI 1.3 to 1.6); p < 0.001),
Neurological conditions affecting the hip pose a considerable challenge in replacement surgery since poor and imbalanced muscle tone predisposes to dislocation and loosening. Consequently, total hip replacement (THR) is rarely performed in such patients. In a systematic review of the literature concerning THR in neurological conditions, we found only 13 studies which described the outcome. We have reviewed the evidence and discussed the technical challenges of this procedure in patients with cerebral palsy, Parkinson’s disease, poliomyelitis and following a
Abstract. Objective. Meta-analysis of clinical trials highlights that non-operative management of degenerative knee meniscal tears is as effective as surgical management. Surgical guidelines though support arthroscopic partial meniscectomy which remains common in NHS practice. Physiotherapists are playing an increasing role in triage of such patients though it is unclear how this influences clinical management and patient outcomes. Methods. A 1-year cohort (July 2019–June 2020) of patients presenting with MRI confirmed degenerative meniscal tears to a regional orthopaedic referral centre (3× ESP physiotherapists) was identified. Initial clinical management was obtained from medical records alongside subsequent secondary care management and routinely collected outcome scores in the following 2-years. Management options included referral for surgery, conservative (steroid injection and rehabilitation), and no active treatment. Outcome scores collected at 1- and 2-years included the Forgotten Joint Score-12 (FJS-12) questionnaire and 0–10 numerical rating scales for worst and average pain. Treatment allocation is presented as absolute and proportional figures. Change in outcomes across the cohort was evaluated with repeated measures ANOVA, with Bonferroni correction for multiple testing, and post-hoc Tukey pair-wise comparisons. As treatment decision is discrete, no direct contrast is made between outcomes of differing interventions but additional explorative outcome change over time evaluated by group. Significance was accepted at p=0.05 and effect size as per Cohen's values. Results. 81 patients, 50 (61.7%) male, mean age 46.5 years (SD13.13) presented in the study timeframe. 32 (40.3%) received conservative management and 49 (59.7%) were listed for surgery. Six (18.8%) of the 32 underwent subsequent surgery and nine of the 49 (18.4%) patients switched from planned surgery to receiving non-operative care. Two post-operative complications were noted, one
Introduction The 2002 NCEPOD report recommended that autopsies should be the subject of a formal external audit process. It is thought that a post mortem would improve the understanding of the pathological events leading up to the death of a patient. The aims of this study were to find out the number of post mortems requested for patients with hip fracture and to establish the cause of death of all hip fracture patients as documented on the death certificate by medical practitioners and the coroner. Patients and Methods A retrospective review of all hip fracture deaths in the year 2000 was performed. The number of cases referred to the coroner for a post mortem and the given verdict was documented. Data regarding the cause of death (as per part 1a on the death certificate) recorded by the medical practitioner and the coroner was established. Results 83 patients with a hip fracture died in hospital in 2000 (mean age 83.6 years, range 58–97 years). There were 30 male and 53 female deaths. 37 patients (44.6%) were referred to the coroner for a post mortem examination. The common causes of death documented by the medical practitioner were: Bronchopneumonia; 27.9%, Congestive cardiac failure; 11.6%, Left ventricular failure; 9.3%,
Aim. Left sided hip fractures are more common but no obvious cause has been identified. Left handedness has previously been associated with an increased risk of fracture for a number of sites but to the best of our knowledge no association between handedness and hip fracture has previously been reported. Methods. 2 separate 6-month prospective reviews of hip fracture patients aged over 65 years-of-age were conducted at 2 different hospitals. Handedness was dete2rmined at the time of admission. The second review focused on the use of walking aids. Patients with a previous
Bilateral one stage total knee replacement (TKR) has a number of advantages. There is one operative procedure and anesthetic and overall recovery time is significantly reduced. It is a more cost-effective procedure in that acute hospital stay is less and although rehabilitation time is greater in the short term, overall it is less. Additionally, if there is a bilateral flexion contracture present there is an inevitable loss of extension if a single knee is operated upon as this knee will assume the position of the unoperated knee. Patients greatly prefer having both knees corrected at one operative setting rather than having to have the inconvenience and pain associated with a second operative procedure at three to six months after the first one. There are potential disadvantages to a one stage procedure. One concern has been that there is more peri-operative morbidity associated with one stage bilateral total knee replacement. In a review of 501 patients undergoing bilateral one stage total knee replacement at the Hospital for Special Surgery (HSS) there were no peri-operative deaths, myocardial infarctions or

Hip fractures are among the most common orthopaedic injuries and represent a growing burden on healthcare as our population ages. Despite improvements in preoperative optimisation, surgical technique and postoperative care, complication rates remain high. Time to surgery is one of the few variables that may be influenced by the medical team. The aim of the present study was to evaluate the impact of time to surgery on mortality and major complications following surgical fixation of hip fractures. Utilising the American College of Surgeons' National Quality Improvement Program (NSQIP) database, we analysed all hip fractures (femoral neck, inter-trochanteric, and sub-trochanteric) treated from 2011 to 2013 inclusively. We divided patients into three groups based on time to surgery: less than one day (<24h), one to two days (24–48h), and two to five days (48–120h). Baseline characteristics were compared between groups and a multivariate analysis performed to compare 30-day mortality and major complications (return to surgery, deep wound infection, pneumonia, pulmonary embolus, acute renal failure,
Spasm or contracture of gastrocnemius causes an equinus deformity of the ankle in both cerebral palsy and hemiplegia. Its release is therefore required in the treatment of those patients who do not respond to conservative measures. The Vulpius procedure is a simple and effective method for the release of gastrocnemius and is particularly indicated when long periods of immobilisation of the foot and ankle are not desirable. We have used this procedure with good results to correct an equinus deformity in 230 adults with a
To progress to a same day surgery program for arthroplasty, it is important that we examine and resolve the issues of why patients stay in the hospital. The number one reason is fear and anxiety of the unknown and of surgical pain. The need for hospital stay is also related to risk arising from comorbidities and medical complications. Patients also need an extended stay to manage the side effects of our treatment, including after effects of narcotics and anaesthesia, blood loss, and surgical trauma. The process begins pre-operatively with an appropriate orthopaedic assessment of the patient and determination of the need for surgery. The orthopaedic team must motivate the patient, and ensure that the expectations of the patient, family and surgeon are aligned. In conjunction with our affiliated hospitalist group that performs almost all pre-admission testing, we have established guidelines for patient selection for outpatient arthroplasty. The outpatient surgical candidate must have failed conservative measures, must have appropriate insurance coverage, and must be functionally independent. Previous or ongoing comorbidities that cannot be optimised for safe outpatient care may include: congestive heart failure, or valve disease; chronic obstructive pulmonary disease, or home use of supplemental oxygen; untreated obstructive sleep apnea with a BMI >40 kg/m2; hemodialysis or severely elevated serum creatinine; anemia with hemoglobin <13.0 g/dl;

Introduction. A fractured hip is the commonest cause of injury related death in the UK. Prompt surgery has been found to improve pain scores and reduce the length of hospital stay, risk of decubitus ulcer formation and mortality rates. The hip fracture Best Practice Tariff (BPT) aims to improve these outcomes by financially compensating services, which deliver hip fracture surgery within 36 hours of admission. Ensuring that delays are reserved for patients with conditions which compromise survival, but are responsive to medical optimisation, would facilitate enhanced outcomes and help to achieve the 36-hour target. We aimed to identify medical conditions associated with patients failing to achieve the 36-hour cut off, and evaluated whether these were justified by calculating their associated mortality risk. Methods. Prospectively collected data from the National Hip Fracture Database (NHFD) and inpatient hospital records and blood results from a single major trauma centre were obtained. Complete data sets from 1361 patients were available for analysis. Medical conditions contributing to surgical delay beyond the BPPT (Best Practice Tariff Target) 36-hour cut off, were identified and analysed using univariate and multivariate regression analyses, whilst adjusting for covariates. The mortality risk associated with each factor contributing to surgical delay was then calculated using univariate and hierarchical regression techniques. Results. A total 1,361 patients underwent hip fracture surgery, of which 537 patients (39.5%) received surgery within 36- hours of admission. The overall median time to surgery from presentation was 23 hours (range 3–36) in patients who did (group 1) and 72 hours (range 36–774) in those who did not (group 2) receive timely surgery. There was no difference between the two groups with respect to age, gender, walking ability, fracture pattern and ASA grade. Following univariate analysis, seven variables including admission source, history of dementia, ischaemic heart disease, MI,

Fractures of the femoral neck in the elderly are associated with significant morbidity and mortality. In the UK, patients with these fractures occupy 20% of orthopaedic beds. Between September 1999 and August 2000 a prospective study was conducted to evaluate the outcome in 36 patients, 24 of them women, with femoral neck fractures treated by uncemented Thompson’s hemi-arthroplasty. The mean age of patients was 71.6 years. All patients had sustained a Garden type-III or IV fracture, and 89% were due to low velocity trauma. Associated conditions were hypertension (66%), diabetes mellitus (27%), dementia (22%), ischaemic heart diseases (16%),

Despite advances in Locking Plate (LP) design, distal femoral fractures remain challenging injuries to treat especially in the elderly where approximately 15–30% develop nonunions secondary to failure of fixation. Aim: To establish the mechanisms of nonunion in our patient population using two different LP systems. Methods: Between December 2002-May 2008, we prospectively collected data on all 67 patients with distal femoral fractures who were treated using a suitable distal femoral LP (LISS, 35 cases, or Periloc, 32 cases). 72% of the patients were female; ages ranged from 25–94 years (ave. 67 years). Many of our patients had a number of significant co-morbidities. Results: The presence of significant co-morbities e.g. Rheumatoid arthritis, long term systemic steroid use,
Objective: To assess the safety and outcome of laminectomy in patients with spinal stenosis operated at the age of 65 years or older. The relation between the duration of the symptoms and results was investigated. Study Design: A retrospective chart analysis with up to 10 years follow-up. Setting: The Spinal Care Unit, Meir Medical Center, Kfar Saba, Israel. Material and Methods: The medical records of all patients who had laminectomy for spinal stenosis at the age of 65 or more in a 10 years period were reviewed. Assessment of pain, ability to perform the basic activities of daily living, transferring dressing and basing before and after the operation was done by a telephone interview. Patient’s self-estimation of the final result of the surgery was also recorded. Results: Two hundred eight-three patients were eligible to participate in the study. They were allocated into 3 groups according to the duration of symptoms before surgery. Group A with symptoms lasting up to 24 months, B with 25–48 months and C with symptoms lasting for more than 48 months. The average age at the time of the operation was 68.9, 72.6 and 71.3 years, respectively. Forty-eight patients died and 18 refused or were not able to participate in the study. The average time of follow-up was 43.3 months, 42.2 in group A, 47.4 in B and 42.8 in C. No significant differences were noticed in the demographic, anesthetic and surgical parameters among the 3 groups. There were no mortality cases in the immediate postoperative period. The overall complication rate was 43.5%, nearly identical in all 3 groups. Two patients had
