Study design: We conducted a prospective cohort study of 448 patients with a variety of spinal metastases. Objective. To compare the predictive value of the Tokuhashi scoring system (T12) and its revised edition (T15) for life expectancy both in the entire study group as well as in the various primary tumor subgroups. Summary of background data. In 1990 Tokuhashi and coworkers formulated a one point-addition-type prognostic scoring system with a total sum of 12 points for preoperative prediction of life expectancy as an adjunct in selecting appropriate treatment. Because the site of the primary tumor influences ultimate survival, the scoring system was revised in 2005 to a total sum of 15 points based on the origin of the primary tumor. Methods. This study included 448 patients with vertebral metastases, all of whom underwent surgical treatment during November 1992 to November 2009 at the Aarhus University Hospital. Data was retrieved from the Aarhus Spinal Metastases Algorithm. Scores based on the T12- and T15 scoring systems were calculated prospectively for each patient. All the patients were divided into three survival groups with different life expectancies according to their score points in both scoring systems. Furthermore, we divided all the patients into different groups dictated by the site of their primary tumor. The predictive value of each scoring system, both in the entire group and in each subgroup determined by the original tumour site, was evaluated by the Log-rank-test. The McNemar's test was used to compare the differences in accuracy rates between these two scoring systems. Survival curves were estimated using the Kaplan-Meier methods. Probability value less than 0.05 was considered statistically significant. Result. For the 448 patients with vertebral metastases, both the T12 and T15 scoring systems showed statistically significant predictive value (T12 group p<0.0001, T15 group p<0.0001, Log-rank test). The correlation between predicted survival period and real survival was significantly higher in T15 (p<0.0001, McNemar's test) than in T12. The further analyses by type of metastases showed that the predictive value of T12 and T15 was found in the prostate (p=0.0003), breast (p=0.0385), other tumor group (p<0.001) and lymphoma (p<0.05). Only T12 displayed predictive value in the colon group (p=0.0011). The accuracy rate of prognosis in T15 was significantly higher in those groups with spinal metastases originating from prostate (p=0.0032), breast (p<0.0001) and lung (p=0.0076). Conclusion. Both the T12 and T15 scoring systems have significant preoperative predictive value in terms of predicting the survival period for the entire vertebral metastases patient group as well as in the prostate, breast, lymphoma, and colon tumor groups. The accuracy rate was significantly improved in T15 for the total study group and in the subgroups of prostate, breast, and lung tumor

The aim of this study was to compare the operating time, length of stay (LOS), adverse events and rate of re-admission for elderly patients with a fracture of the hip treated using either general or spinal anaesthesia. Patients aged ≥ 70 years who underwent surgery for a fracture of the hip between 2010 and 2012 were identified from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Of the 9842 patients who met the inclusion criteria, 7253 (73.7%) were treated with general anaesthesia and 2589 (26.3%) with spinal anaesthesia. On propensity-adjusted multivariate analysis, general anaesthesia was associated with slightly increased operating time (+5 minutes, 95% confidence interval (CI) +4 to +6, p < 0.001) and post-operative time in the operating room (+5 minutes, 95% CI +2 to +8, p < 0.001) compared with spinal anaesthesia. General anaesthesia was associated with a shorter LOS (hazard ratio (HR) 1.28, 95% CI 1.22 to 1.34, p < 0.001). Any adverse event (odds ratio (OR) 1.21, 95% CI 1.10 to 1.32, p < 0.001), thromboembolic events (OR 1.90, 95% CI 1.24 to 2.89, p = 0.003), any minor adverse event (OR 1.19, 95% CI 1.09 to 1.32, p < 0.001), and blood transfusion (OR 1.34, 95% CI 1.22 to 1.49, p < 0.001) were associated with general anaesthesia. General anaesthesia was associated with decreased rates of urinary tract infection (OR 0.73, 95% CI 0.62 to 0.87, p < 0.001). There was no clear overall advantage of one type of anaesthesia over the other, and surgeons should be aware of the specific risks and benefits associated with each type.

A total of 11 patients with combined traumatic injuries of the brachial plexus and spinal cord were reviewed retrospectively. Brachial plexus paralysis in such dual injuries tends to be diagnosed and treated late and the prognosis is usually poor. The associated injuries, which were all on the same side as the plexus lesion, were to the head (nine cases), shoulder girdle (five), thorax (nine) and upper limb (seven). These other injuries were responsible for the delayed diagnosis of brachial plexus paralysis and the poor prognosis was probably because of the delay in starting treatment and the severity of the associated injuries. When such injuries are detected in patients with spinal cord trauma, it is important to consider the possibility of involvement of the brachial plexus

Study Design. Retrospective review. Objective. To report the technique and results of vertebral column decancellation (VCD) for the management of sharp angular spinal deformity. Summary of Background Data. The goal of management of sharp angular spinal deformity is to realign the spinal deformity and safely decompress the neurological elements. However, some shortcomings related to current osteotomy treatment for these deformities are still evident. Methods. From January 2004 to March 2007, 45 patients (27 males/18 females) with severe sharp angular spinal deformities at our institution underwent VCD. The diagnoses included 29 congenital kyphoscoliosis and 16 Pott's deformity. The operative technique included multilevel VCD, disc removal, osteoclasis of the concave cortex, compression of the convex cortex accompanied by posterior instrumentation with pedicle screws. Preoperative and postoperative radiographic evaluation was performed. Intraoperative, postoperative and general complications were noted. Results. For a kyphosis type deformity, an average of 2.2 vertebrae was decancellated (range, 2to 4 vertebrae). The mean preoperative kyphosis was +98.6° (range, 82° to 138°), and the meankyphosis in the immediate postoperative period was +16.4° (range, 4° to 30°) with an averagepostoperative correction of +82.2° (range, 61° to 124°). For a kyphoscoliosis type deformity, thecorrection rate was 64% in the coronal plane (from 83.4° to 30.0°) postoperatively and 32.5°(61% correction) at 2 years follow-up. In the sagittal plane, the average preoperative curve of88.5° corrected to 28.6° immediately after surgery and to 31.0° at 2 years follow-up. All patientshad solid fusion at latest follow-up. Complications were encountered in 8 patients (17.8%) andincluded transient neurological deficit and complete paralysis (n = 1). Conclusion. Single stage posterior vertebral column decancellation (VCD) is an effective option to manage severe sharp angular spinal deformities

PURPOSE OF THE STUDY. The anterior approach to the thoracic and lumbar spine is used with increasing frequency for various indications. With the advent of prosthetic intervertebral disc replacement, its use has become even more frequent and has often been associated with serious complications. The aim of this study was to evaluate vascular complications in patients who underwent anterior spinal surgery of the thoracic and lumbar spine. MATERIAL. We performed a total of 531 operations of the thoracolumbar spine from the anterior approach. In 12 cases, after exposure of the body of the first or second thoracic vertebrae, we employed the Smith-Robinson technique to expose the cervical spine. We used sternotomy in six, posterolateral thoracotomy in 209, pararectal retroperitoneal approach in 239, anterolateral lumbotomy in 58 and the transperitoneal approach in seven patients. The aim of surgery was somatectomy in 190 patients and discectomy in 341 patients. Sternotomy and transperitoneal approaches were carried out by a thoracic or vascular surgeon and all the other procedures were done by the first author. The indications for spinal surgery included an accident in 171, tumour in 56, spondylodiscitis in 43 and a degenerative disease in 261 patients. METHODS. The Smith-Robinson approach was used for exposure of T1 or T2. Sternotomy was indicated for treatment of T2–T4 and also T1 in the patients with a short, thick neck. Access to T3–L1 was gained by posterolateral thoracotomy, in most cases performed as a minimally invasive transpleural procedure. For access to the lumbar spine we usually used the retroperitoneal approach from a pararectal incision or lumbotomy. We preferred the pararectal retroperitoneal approach in L2–S1 degenerative disease, L5 fractures, and L5–S1 spondylodiscitis. We carried out lumbotomy in patients with trauma, tumors and L1–L4 spondylodiscitis. The transperitoneal approach from lower middle laparotomy was used only in tumors at L5 or L4. The patients were followed up for 2 to 96 months (average, 31.4 months) after anterior spinal surgery. RESULTS. In 12 patients treated by the Smith-Robinson procedure and in six patients undergoing sternotomy, neither early nor late signs of any injury to major blood vessels or internal organs were recorded. The 209 patients with posterolateral thoracotomy were also free from any signs of vascular injury, but trauma to the thoracic duet was recorded in one case. We found injury to major blood vessels in three patients in the group treated by the pararectal retroperitoneal procedure. In the total of 531 anterior spinal surgery procedures this accounts for 0.56 %; of the 304 lumbar operations and 239 pararectal retroperitoneal operations it is 0.99 % and 1.26 %, respectively. In one patient the vascular injury was associated with trauma to the ureter. CONCLUSIONS. The technique of anterior approach is safe only in the hands of experienced spinal surgeons with long experience. In institutions where anterior spinal surgery is not a routine method it is advisable to involve a vascular or cardiac surgeon. However, the most important point is to know when not to operate

Introduction. This is the first study to illustrate spinal fracture distribution and the impact of different injury mechanisms on the spinal column during contemporary warfare. Methods Retrospective analysis of Computed Tomography (CT) spinal images entered onto the Centre for Defence Imaging (CDI) database, 2005-2009. Isolated spinous and transverse process fractures were excluded to allow focus on cases with implications for immediate management and prospective disability burden. Fractures were classified by anatomical level and stability with validated systems. Clinical data regarding mechanism of injury and associated non-spinal injuries for each patient was recorded. Statistical analysis was performed by Fisher's Exact test. Results 57 cases (128 fractures) were analysed. Ballistic (79%) and non-ballistic (21%) mechanisms contribute to vertebral fracture and spinal instability at all regions of the spinal column. There is a low incidence of cervical spine fracture, with these injuries predominantly occurring due to gunshot wounding. There is a high incidence of lumbar spine fractures which are significantly more likely to be caused by explosive devices than gunshot wounds (p<0.05). 66% of thoracolumbar spine fractures caused by explosive devices were unstable, the majority being of a burst configuration. Associated non-spinal injuries occurred in 60% of patients. There is a strong relationship between spinal injuries caused by explosive devices and lower limb fractures Conclusion Explosive devices account for significant injury to both combatants and civilians in current conflict. Injuries to the spine by explosions account for greater numbers, associated morbidity and increasing complexity than other means of injury

BACKGROUND. From 1995 the cost of litigation to the National Health Service (NHS) from surgical procedures has been over 1.3 billion GBP. Spinal patients can present diagnostic challenges and the consequences of delayed diagnosis and surgical complications can be devastating. As a consequence these patients represent a high risk when surgeons seek to indemnify themselves. We therefore, aim to highlight the litigation patterns for these injuries within the United Kingdom. METHOD. Data was obtained from the NHS Litigation Authority from 2002 to 2010 which was analysed. RESULTS. Of the 236 claims, 144 were related to trauma or acute diagnostic issues and 92 from elective surgery. The total financial burden to the NHS came to 60.5 million GBP/72.5 million Euros. Of this sum 42.8 million GBP/51.3 million Euros were paid in damages, and the remaining 29% in legal costs. The financial costs were on average similar for trauma and elective cases. The most frequent cause of successful litigation for trauma were, missed fractures (41.7%), missed cauda equina (23.6%) and spinal infection (11.8%). The emergency department (43.8%), orthopaedic surgery (28.5%) and Medicine (13.9) bore the brunt of the claims. For elective surgery, Spinal Damage(19.8%), failure in Post-Operative Care (15.4%), Infection (11%) and Wrong Level Surgery, Cauda Equina and Surgical Failure at 9.9%. were likely to result in a successful claim, and the litigation burden was felt by the orthopaedic(60.4%), Neurosurgery(18.7%) and other surgical disciplines (11%). CONCLUSION. Acute spinal fractures, cord compression and infection should be considered in patients in the emergency department setting, with appropriate examination and investigations for uncertainty. A lack of awareness of at risk cases increases the likelihood of a pay-out and sums involved. For elective spinal surgery, a failure in the consenting process and the technical skill of the surgeon are likely to result in a pay-out. A failure to identify post-operative complications such as infection and thromboembolism are also indefensible. Protecting patients intra-operatively and maintaining high technical expertise and vigilance post-operative in an adequately consented patient may decrease litigation rates

Background. It is unclear which form of anaesthesia is the most favourable in primary total hip replacement (THR) surgery. A recently published systematic review of modern anaesthesia techniques in primary THR surgery (Macfarlane 2009) was not able to show any convincing benefit of regional or general anaesthesia. One retrospective study that examined anaesthesia and leg length (Sathappan 2008), found an increased incidence of leg length difference > 5 mm in those patients who were operated with regional anaesthesia. Our department used a mini invasive approach in supine as standard procedure in THR. The type of anaesthesia that is chosen is up to the individual anaesthetist. Purpose. We wanted to see if there was any correlation between type of anaesthesia and leg length, total time spent in theatre and recovery room, postoperative hospital stay, blood loss or operating time in primary THR surgery with a mini invasive approach in supine. Materials and Methods. Our study was a retrospective study of 170 primary THR patients. All patients received an uncemented Corail stem and a cemented Marathon cup. Patients with abnormal anatomy, BMI > 46, simultaneous removal of internal fixation or incomplete data were excluded in the analysis. Radiograpic leg length was measured using the inter teardrop line and the lesser trochanter. Results. 99 patients were operated on with spinal anaesthesia and 71 with total intravenous anaesthesia (TIVA). There were 65% women in both groups. Average age was 74 years (32–95) in the spinal anaesthesia group and 67 years (38–93) in the TIVA group. We found no significant difference in the average operating time (spinal 65 min, TIVA 64 min), drop in haemoglobin to the first postoperative day (spinal 16%, TIVA 16%), postoperative hospital stay (Spinal 1.4 days, TIVA 1.4) or in transfusion rate (spinal 1%, TIVA 1.4%). We found a significant difference in the proportion of patients with a leg length difference of more than 7 mm (Spinal 22%, TIVA 6%, p = 0.02) and the average total time spent in theatre and post-operative department (spinal 325 min, TIVA 293 min, p < 001). Discussion. The study is retrospective and is therefore fettered by the limitations inherent in such a study. Our study seems to confirm the earlier findings that the type of anaesthesia can affect leg length in primary THR. It is speculated that spinal anaesthesia has a more unpredictable effect on muscular tension which could explain this

Success treating AIS with bracing is related to time worn and scoliosis severity. Temperature monitoring can help patients comply with their orthotic prescription. Routinely collected temperature data from the start of first brace treatment was reviewed for 14 patients. All were female with an average age of 12.4 years (range 10.3–14.6) and average 49o Cobb angle (30–64).

Our current service recommendation is brace wear for 20 hours a day. Patients complied with this prescription 38.0% of the time, with four patients averaging this or more. Average brace wear was 16.3 hours per day (3.5–22.2).

There were 13 patients who had completed brace treatment. The majority had surgery (7/13; 54%) or were considering surgery (1/13; 8%). There were 5 who did not wish surgery at discharge (5/13; 38%); 1 achieved a 40o Cobb angle, with 4 larger (53o;53o;54o;68o). The Bracing in AIS Trial (BrAIST) study measured “success” as less than a 50o Cobb angle, so using this metric our cohort has had a single “success”.

Temperature monitors allowed an analysis of when patients were achieving their brace wear. When comparing daywear (8am-8pm) to nightwear (8pm-8am), patients wore their brace an average of 7.6 hours a day (2.5–11.2) and 8.7 hours a night (0.4–11.5).

We conclude the minority of our patients comply with our current 20 hour orthotic prescription. The “success” of brace treatment is lower than comparison studies despite higher average compliance but starting with a larger scoliosis. Brace wear is achieved during both the day and night.

Objectives. To determine the limits of spinal displacement before the onset of neurophysiological changes during spinal surgery. Assessing if the type of force applied or the section of the adjacent nerve roots increases the tolerance to displacement. Methods. Experimental study in 21 domestic pigs. Three groups were established according to the displacing force applied to the cord: separation (group 1, n=7), root stump pull (group2, n=7) and torque (group3, n=7). Successive records of cord-to-cord motor evoked potential were obtained. The displacing force was removed immediately when neurophysiological changes observed. The experiment was repeated after sectioning the adjacent nerve roots. Results. The diameter of the dura in the study area was 7.2 ± 1 mm. Group 1: evoked potential changes appeared with displacement of 10.1 ± 1.6 mm with roots unharmed and 15.3 ± 4.7 mm (p <0.01) with section of four adjacent roots. Group 2: evoked potential disturbance at 17.5 ± 4.7 mm, which increased to 23.5 ± 2.1 mm (p <0.05) after cutting the two contralateral roots. Group 3: cord allowed torque of 95.3° ± 9.2 increasing to 112.4 ° ± 7.1 ° if the contralateral roots were cut. Except in two cases in group 3 (torsion), the potentials were normalized immediately after releasing the deforming force. Discussion. This experimental study shows that it is possible to surgically displace the medulla a distance superior to the diameter of the dura without detecting neurophysiological changes. The limits of cord displacement may be increased by the section of the adjacent nerve roots and if the tensile force is applied by traction of the root stumps. These findings support the neurological safety of spine deformity correction by isolated posterior approach, obviating the morbidity related to an additional anterior procedure

Introduction. While there is a desperate need for effective treatments for acute spinal cord injury (SCI), the clinical validation of novel therapeutic interventions is severely hampered by the need to recruit relatively large numbers of patients into clinical trials for sufficient statistical power. While a centre might annually admit 100 acute SCI patients, only a fraction may satisfy the basic inclusion criteria for an acute clinical trial, which typically requires patients of a certain injury severity (eg ASIA A), within a specific time window (eg. 12 hours from injury), and without other major injuries or conditions that would cloud the baseline neurologic assessment. This study was conducted to define that “fraction” of SCI patients that would theoretically satisfy standard inclusion criteria of an acute clinical trial. Methods. Using a local database, we reviewed patients admitted to our Level 1 trauma center with a complete (ASIA A) or an incomplete (ASIA B, C and D) acute SCI involving bony spinal levels between C0 and sacrum. All patients admitted over the 4 year period from 2005 to 2009 were reviewed. Demographic information and data about the patients' SCI and other injuries were reviewed. We then determined how many of the total number of SCI patients would be eligible for enrolment into a hypothetical acute clinical trial that required a valid baseline assessment of neurologic impairment, and an enrolment window of either 12 hours, 24 hours, or 48 hours. Results. 408 acute traumatic SCI patients were admitted over the 4 year period. 253 of 408 (62%) patients presented within 12 hours of injury, 60 (15%) between 12–24 hours, and 28 (7%) between 24–48 hours. 42% of patients were ASIA A, 13% B, 18% C and 27% D. The number of patients who presented with injuries or other conditions that would exclude them from enrolment was relatively high: 4% had penetrating injuries, 12% had illicit drug use, and 20% had either alcohol intoxication or head injuries which precluded a valid baseline neurologic examination. Conclusions. Out of a total of 408 patients admitted over 4 years, the number who would have been optimistically eligible for an acute neuroprotective trial was disappointingly small. Given that acute clinical trials are increasingly interested in cervical ASIA A patients (in whom segmental motor recovery can be assessed), the number of such patients who would actually be eligible for an acute intervention was surprisingly low. Given that additional inclusion/exclusion criteria would also be applicable in a real clinical trial, the true number of “eligible” or “recruitable” patients is conservatively even lower. This study is the first to quantify this challenging aspects of conducting acute SCI clinical trials, and provides valuable information for those planning such initiative

INTRODUCTION

Spinal injuries in children are rare and account for a low proportion of all childhood injuries. Because of higher mobility and elasticity of the spine and a lower body mass in children, spinal injuries are not frequent and represent only 2 to 5 % of all spinal injuries.

Lowest instrumented vertebra (LIV) selection is critical to preventing complications following posterior spinal arthrodesis (PSA) for thoracolumbar/lumbar adolescent idiopathic scoliosis (TL/L AIS), but evidence guiding LIV selection is limited. This study aimed to investigate the efficacy of PSA using novel unilateral convex segmental pedicle screw instrumentation (UCS) in correcting TL/L AIS, to identify radiographic parameters correlating with distal extension of PSA, and to develop a predictive equation for distal fusion extension using these parameters. We reviewed data (demographic, clinical, radiographic, and SRS-22 questionnaires) preoperatively to 2-years' follow-up for TL/L AIS patients treated by PSA using UCS between 2006 to 2011. 53 patients were included and divided into 2 groups: Group-1 (n=36) patients had PSA between Cobb-to-Cobb levels; Group-2 (n=17) patients required distal fusion extension. A mean curve correction of 80% was achieved. Mean postoperative LIV angle, TL/L apical vertebra translation (AVT), and trunk shift were lower than previous studies. Six preoperative radiographic parameters significantly differed between groups and correlated with distal fusion extension: thoracic curve size, thoracolumbar curve size, LIVA, AVT, lumbar flexibility index, and Cobb angle on lumbar convex bending. Regression analysis optimised an equation (incorporating the first five parameters) which is 81% accurate in predicting Cobb-to-Cobb fusion or distal extension. SRS-22 scores were similar between groups. We conclude that TL/L AIS is effectively treated by PSA using UCS, six radiographic parameters correlate with distal fusion extension, and a predictive equation incorporating these parameters reliably informs LIV selection and the need for fusion extension beyond the caudal Cobb level

Purpose

compare the radiological results in sagittal balance correction obtained with pedicle subtraction osteotomy (PSO) versus anterior-posterior osteotomy (APO) by double approach in adults.

Introduction

Short-segment posterior instrumentation for spine fractures is threatened by unacceptable failure rates. Two important design objectives of pedicle screws, bending and pullout strength, may conflict with each other.

Aims. The aims of this study were to assess the pre- and postoperative incidence of deep vein thrombosis (DVT) using routine duplex Doppler ultrasound (DUS), to assess the incidence of pulmonary embolism (PE) using CT angiography, and to identify the factors that predict postoperative DVT in patients with a pelvic and/or acetabular fracture. Methods. All patients treated surgically for a pelvic and/or acetabular fracture between October 2016 and January 2020 were enrolled into this prospective single-centre study. The demographic, medical, and surgical details of the patients were recorded. DVT screening of the lower limbs was routinely performed using DUS before and at six to ten days after surgery. CT angiography was used in patients who were suspected of having PE. Age-adjusted univariate and stepwise multiple logistic regression analysis were used to determine the association between explanatory variables and postoperative DVT. Results. A total of 191 patients were included. A DVT was found preoperatively in 12 patients (6.3%), of which six were proximal. A postoperative DVT was found in 42 patients (22%), of which 27 were proximal. Eight patients (4.2%) had a PE, which was secondary to a DVT in three. None of the 12 patients in whom a vena cava filter was implanted prophylactically had a PE. Multivariate logistic regression analysis indicated that the association with the need for spinal surgery (odds ratio (OR) 19.78 (95% confidence interval (CI) 1.12 to 348.08); p = 0.041), intramedullary nailing of a long bone fracture (OR 4.44 (95% CI 1.05 to 18.86); p = 0.043), an operating time > two hours (OR 3.28 (95% CI 1.09 to 9.88); p = 0.035), and additional trauma surgery (OR 3.1 (95% CI 1.03 to 9.45); p = 0.045) were statistically the most relevant independent predictors of a postoperative DVT. Conclusion. The acknowledgement of the risk factors for the development of a DVT and their weight is crucial to set a threshold for the index of suspicion for this diagnosis by medical staff. We suggest the routine use of the DUS screening for DVT in patients with a pelvic and/or acetabular fracture before and six to ten days after surgery.

Aims. COVID-19 necessitated abrupt changes in trauma service delivery. We compare the demographics and outcomes of patients treated during lockdown to a matched period from 2019. Findings have important implications for service development. Methods. A split-site service was introduced, with a COVID-19 free site treating the majority of trauma patients. Polytrauma, spinal, and paediatric trauma patients, plus COVID-19 confirmed or suspicious cases, were managed at another site. Prospective data on all trauma patients undergoing surgery at either site between 16 March 2020 and 31 May 2020 was collated and compared with retrospective review of the same period in 2019. Patient demographics, injury, surgical details, length of stay (LOS), COVID-19 status, and outcome were compared. Results. There were 1,004 urgent orthopaedic trauma patients (604 in 2019; 400 in 2020). Significant reductions in time to theatre and LOS stay were observed. COVID-19 positive status was confirmed in 4.5% (n = 18). The COVID-19 mortality rate was 1.8% (n = 7). Day-case surgery comprised 47.8% (n = 191), none testing positive for COVID-19 or developing clinically significant COVID-19 symptoms requiring readmission, at a minimum of 17 days follow-up. Conclusion. The novel split-site service, segregating suspected or confirmed COVID-19 cases, minimized onward transmission and demonstrated improved outcomes regarding time to surgery and LOS, despite altered working patterns and additional constraints. Day-surgery pathways appear safe regarding COVID-19 transmission. Lessons learned require dissemination and should be sustained in preparation for a potential second wave or, the return of a “normal” non-COVID workload.

Aims

The aim of this study was to compare the early postoperative mortality and morbidity in older patients with a fracture of the femoral neck, between those who underwent total hip arthroplasty (THA) and those who underwent hemiarthroplasty.

Aims

The aim of this study was to investigate the association between additional rehabilitation at the weekend, and in-hospital mortality and complications in patients with hip fracture who underwent surgery.

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.
