Introduction. We aimed to study the rates of both surgical and medical complications associated with femoral diaphysis fracture fixation with intramedullary nailing including all fracture mechanisms. Additionally, we investigated whether the trauma energy has an impact on the complication risk. Method. In this retrospective cohort study, the health records of 491 patients with 503 femoral fractures, who underwent surgery between May 2007 and May 2022 in Tampere University Hospital, were reviewed. Patients who underwent a primary operation with a reamed rigid intramedullary nail for a diaphyseal femoral fracture and whose follow-ups were organized at the same hospital district, were included. Based on those criteria, 57.5% were included for analysis (279 patients with 289 fractures). The complications were then recorded by chart review. To investigate the impact of trauma energy on complication risk, we compared complication proportions in high- and low-energy groups and calculated odds ratios. Result. The crude percentage of 30-day mortality was 2.1% (6 of 289) based on information obtained from the patients’ records. The overall proportion of complications was 22.5%. The risk of any medical complication was 2.8%, whereas the risk of surgical complication was 19.8%. The risk of complications was nearly twice as high in high-energy fractures compared to low-energy fractures, with an odds ratio (OR) of 1.92, 95% CI 1.03-3.75. The risk of reoperations was significantly increased in high-energy traumas (OR 2.46, CI 1.25-5.24). Conclusion. This study reveals a 2.1% risk of thirdy-day mortality and a 22.5% risk of overall complications, predominantly of a surgical type. The complication risk, especially the risk of surgical complications, is higher among the patients with fractures caused by high-energy injury compared to low-energy fractures, highlighting the importance of timely identification of those complications for providing better postoperative care

Aims

The prevalence of obesity is increasing substantially around the world. Elevated BMI increases the risk of complications following total hip arthroplasty (THA). We sought to evaluate trends in BMI and complication rates of obese patients undergoing primary THA over the last 30 years.

Aims

The aim of this study was to determine whether obesity had a detrimental effect on the long-term performance and survival of medial unicompartmental knee arthroplasties (UKAs).

Aims

The primary aim of this study is to quantify and compare outcomes following a dorsally displaced fracture of the distal radius in elderly patients (aged ≥ 65 years) who are managed conservatively versus with surgical fixation (open reduction and internal fixation). Secondary aims are to assess and compare upper limb-specific function, health-related quality of life, wrist pain, complications, grip strength, range of motion, radiological parameters, healthcare resource use, and cost-effectiveness between the groups.

The October 2024 Arthroplasty Roundup³⁶⁰ looks at: Breaking the mould: female representation in arthroplasty surgery remains low, with elbow leading the way; Post COVID-19: where are we with the 'catch up' in England and Wales?; Prevalence and clinical impact of sarcopenia in patients undergoing total joint replacement: a systematic review and a meta-analysis; Total joint replacement and sleep: the state of the evidence.

Aims

The purpose of this study was to determine the association between prior sleeve gastrectomy in patients undergoing primary total hip and knee arthroplasty, and 90-day complications, incidence of revision arthroplasty, and patient-reported outcome scores at final follow-up.

While obesity is associated with an increased risk of complications after total hip arthroplasty (THA) the relationship between body mass index (BMI) and the risk of early postoperative complications has not been fully characterized. This study sought to describe the relationship between BMI and the risk of early postoperative complications, including periprosthetic joint infection (PJI), composite surgical, and composite medical complications. Primary, elective THAs performed from 2016–2021 were identified using the Premier Healthcare Database (PHD). The study's primary outcome was the diagnosis of PJI within 90 days of THA. Using BMI as a continuous variable, logistic regression was used to develop restricted cubic splines (RCSs) to determine the impact of BMI on PJI risk. Bootstrap simulation was used to identify an inflection point in the final RCS model. The same technique was used to characterize the effects of BMI on composite medical and surgical complications. We found that PJI risk increased exponentially beyond a BMI cutpoint of 37.4 kg/m. 2. Relative to the cutpoint, patients with a BMI of 40 or 50 kg/m. 2. were at a 1.22- and 2.55-fold increased risk of developing PJI, respectively. Surgical complications increased at a BMI of 32 kg/m. 2. and medical complications increased at a BMI of 39 kg/m. 2. Relative to these cutpoints, patients with a BMI of 50 kg/m. 2. were at a 1.36- and 2.07-fold increased risk of developing medical and surgical complications, respectively. The results of this study indicate a non-linear relationship between patient BMI and early postoperative risk of PJI, composite medical complications, and composite surgical complications following THA. The identified cutpoints with associated odds ratios can serve as tools to help risk-stratify and counsel patients seeking primary THA

Debate continues about the best treatment for patients over 65 years with non-displaced subcapital hip fractures: internal fixation (IF) or hemiarthroplasty (HA). Surgical aggression, mortality, complications and recovery of walking ability after 1year have been compared between both treatments. Match-paired comparison of 2 retrospective cohorts. 220 patients with IF vs 220 receiving a cemented bipolar HA. Matching by age (82.6±7.16 years (65–99)), sex (74.5% women), year of intervention (2013–2021) and ASA scale (24.2% ASA II, 55.8% III, 20.0% IV). Age (p=0.172), sex (p=0.912), year of intervention (p=0.638) and ASA scale (p=0.726) showed no differences. Surgical aggression smaller in IF: Surgical time (p< 0,00001), haemoglobin/haematocrit loss (p <0,00001), need for transfusion (p<0,00008), in-hospital stay (p<0,00001). Mortality: higher in-hospital for hemiarthroplasties (12 deaths (5.5%) vs 1 (0.5%) (p=0.004) (RR=12, 1.5–91.5)). But no significant differences in 1-month (13 hemiarthroplasties, 6%, vs 9 osteosynthesis, 4.1%) and 1-year mortality (33 hemiarthroplasties, 15%, vs 35, 16%). Medical complications: no differences in urinary/respiratory infections, heart failure, ictus, myocardial infarction, digestive bleeding, pressure sores or pulmonary embolus (p=0.055). Surgical complications: no significant differences. HA: 6 intraoperative (2,7%) and 5 postoperative periprosthetic fractures (2,3%), 5 infections (2,3%), 10 dislocations (4,5%), 3 neurovascular injuries. IF: 10 acute fixation failures (4,5%), 2 infections (0,9%), 9 non-unions (4,1%), 16 ischemic necrosis (7,3%). Functional results: no significant differences; 12 patients in each group (5,5%) never walked again (p=1), 110 HA (50%) and 100 IF (45.5%) suffered worsening of previous walking ability (p=0.575), 98 HA (44%) and 108 IF patients (49%) returned to pre-fracture walking ability (p=0.339). Fixation with cannulated screws may be a better option for non-displaced femoral neck fractures because recovery of walking ability and complications are similar, while surgical aggression and in-hospital mortality are lower

The August 2024 Research Roundup³⁶⁰ looks at: Effect of vitamin D deficiency on periprosthetic joint infection and complications after primary total joint replacement; Postoperative angiotensin receptor blocker use associated with decreased rates of manipulation under anaesthesia in patients undergoing total knee arthroplasty; Central sensitization: the missing link between psychological distress and poor outcome following primary total knee arthroplasty; Thromboprophylaxis for the trauma and orthopaedic surgeon; Life expectancy after treatment of metastatic bone disease: an international trend analysis.

Aims

The use of multimodal non-opioid analgesia in hip fractures, specifically acetaminophen combined with non-steroidal anti-inflammatory drugs (NSAIDs), has been increasing. However, the effectiveness and safety of this approach remain unclear. This study aimed to compare postoperative outcomes among patients with hip fractures who preoperatively received either acetaminophen combined with NSAIDs, NSAIDs alone, or acetaminophen alone.

Aims

The number of revision arthroplasties being performed in the elderly is expected to rise, including revision for infection. The primary aim of this study was to measure the treatment success rate for octogenarians undergoing revision total hip arthroplasty (THA) for periprosthetic joint infection (PJI) compared to a younger cohort. Secondary outcomes were complications and mortality.

The recruitment drive, investment and collaboration within Betsi Cadwaladr University Health Board (BCUHB) sites providing specialist lower limb arthroplasty and trauma service has evolved over last few years with aims to improve patient care and reduce reliance on tertiary referral centres. Through our service-evaluation project, we reviewed the results of treatment provided for periprosthetic femur fractures (PPFFs) presenting to BCUHB sites over last 4 years. We retrospectively reviewed consecutive PPFFs admitted at three BCUHB sites from January’20 to June’23 with mean follow-up of 20.8 ± 13.2 (8–49) months [n=161; Mean age: 82.2 ± 8.5 (59–101) years, Females:107]. Over the review period we noted a 23% increase in service demand for care of PPFFs. Majority were managed surgically [132/161] [38 revision arthroplasties; 94 ORIFs] at BCUHB sites and two patients were referred to tertiary centre. Average time to surgery was 3.5 days. 90% of the PPFFs were managed successfully with 10% (16/159) having orthopaedic complications needing further intervention. 6.3 (10/159) had medical complications and did not need orthopaedic re-intervention. In our series, 12-month re-operation rate was 6.1% (8/132) and 1-month, 3-month and 1-year mortality rate was 6.3%, 11.3% and 21.4% respectively. These results are comparable to the published results of PPFF management at tertiary centres. Potential cost savings compared to transfer to tertiary centre for PPFF management was £2.31 million. Thus, it is possible to successfully provide adequate care for PPFFs at DGHs and efforts should be made to appropriately equip and adequately staff DGHs, to provide service for local PPFF care

Aims

The purpose of this study was to compare reoperation and revision rates of double plating (DP), single plating using a lateral locking plate (SP), or distal femoral arthroplasty (DFA) for the treatment of periprosthetic distal femur fractures (PDFFs).

The June 2024 Hip & Pelvis Roundup³⁶⁰ looks at: Machine learning did not outperform conventional competing risk modelling to predict revision arthroplasty; Unravelling the risks: incidence and reoperation rates for femoral fractures post-total hip arthroplasty; Spinal versus general anaesthesia for hip arthroscopy: a COVID-19 pandemic- and opioid epidemic-driven study; Development and validation of a deep-learning model to predict total hip arthroplasty on radiographs; Ambulatory centres lead in same-day hip and knee arthroplasty success; Exploring the impact of smokeless tobacco on total hip arthroplasty outcomes: a deeper dive into postoperative complications.

Aims

The Birmingham Hip Resurfacing (BHR) was introduced in 1997 to address the needs of young active patients using a historically proven large-diameter metal-on-metal (MoM) bearing. A single designer surgeon’s consecutive series of 130 patients (144 hips) was previously reported at five and ten years, reporting three and ten failures, respectively. The aim of this study was to extend the follow-up of this original cohort at 25 years.

There is an increasing demand worldwide for total hip arthroplasty in patients over 80 years old. This study is the largest of its kind reporting long term outcomes and clinical survivorship of patients over 80 years old undergoing THR. 13171 patients 80 years or older who underwent THR between 2000 and 2019 were included. Demographic and operative data was collected including age, sex, laterality, date of surgery and operative technique. Presence and date of complications were collected. Data was also collected for the same time period on 80910 patients aged 51–79 years undergoing THR for comparison. 4103 (31.2%) male and 9068 female (68.8%) patients were included in the 80year old cohort. Median age was 83 (IQR 81–83, range 80–98). 32682 (40.4%) male and 48227 (59.6%) females were included in the 50–79year old cohort. Median age was 68 (IQR 62–73, range 50–79). The 80 cohort was more likely to sustain post operative complications in the 6 months following surgery including DVT (81/13171 vs 364/80910, P<0.05), myocardial infarction (177/13171 vs 341/80910, P<0.05), acute renal failure (371/12800 vs 812/80910 P<0.05). The 50–79year old cohort was over twice as likely to undergo revision surgery than the 80 year old cohort (HR 2.55, 95% CI 2.216–2.932, p<0.001). Of those requiring revision surgery, the elderly cohort were more likely to undergo earlier revision surgery (378days, 95%CI 236–519d vs 1586days, 95%CI 1471–1700d, p<0.001). In those undergoing revision surgery, a higher proportion were done for infection in the 80 year old cohort (39/219 (17.8%) vs 215/2809 (7.7%), p<0.05. This study demonstrates good outcomes in terms of medical complications and a low overall risk of requiring revision surgery in patients 80years old undergoing THR. Patients over the age of 80 should be counselled on the relatively increased risk of medical complications post operatively

Aims

Fractures of the humeral shaft represent 3% to 5% of all fractures. The most common treatment for isolated humeral diaphysis fractures in the UK is non-operative using functional bracing, which carries a low risk of complications, but is associated with a longer healing time and a greater risk of nonunion than surgery. There is an increasing trend to surgical treatment, which may lead to quicker functional recovery and lower rates of fracture nonunion than functional bracing. However, surgery carries inherent risk, including infection, bleeding, and nerve damage. The aim of this trial is to evaluate the clinical and cost-effectiveness of functional bracing compared to surgical fixation for the treatment of humeral shaft fractures.
