Aims. The aim of this study was to investigate the association between the type of operation used to treat a trochanteric fracture of the hip and 30-day mortality. Patients and Methods. Data on 82 990 patients from the National Hip Fracture Database were analyzed using generalized linear models with incremental case-mix adjustment for patient, non-surgical and surgical characteristics, and socioeconomic factors. Results. The use of short and long intramedullary nails was associated with an increase in 30-day mortality (adjusted odds ratio (OR) 1.125, 95% confidence interval (CI) 1.040 to 1.218; p = 0.004) compared with the use of

We studied the biomechanical behaviour of three sliding fixation devices for trochanteric femoral fractures. These were a titanium alloy sideplate and lag screw, a titanium alloy sideplate and dome plunger with cement augmentation, and a stainless-steel sideplate and lag screw. We used 18 mildly osteoporotic cadaver femora, randomly assigned to one of the three fixation groups. Four displacement and two strain gauges were fixed to each specimen, and each femur was first tested intact (control), then as a two-part fracture and then as a four-part intertrochanteric fracture. A range of physiological loads was applied to determine load-bearing, load-sharing and head displacement. The four-part-fracture specimens were subsequently tested to failure to determine maximum fixation strengths and modes of failure. The dome-plunger group failed at a load 50% higher than that of the stainless-steel lag-screw group (p <
0.05) and at a load 20% higher than that of the titanium-alloy lag-screw group (NS). All 12 lag-screw specimens failed by cut-out through the femoral head or neck, but none of the dome-plunger group showed movement within the femoral head when tested to failure. Strain-gauge analysis showed that the dome plunger produced considerably less strain in the inferior neck and calcar region than either of the lag screws. Inferior displacement of the femoral head was greatest for the dome-plunger group, and was due to sliding of the plunger. The dome plunger with cement augmentation was able to support higher loads and did not fail by cut-out through the femoral head.(ABSTRACT TRUNCATED AT 250 WORDS)

Aims. The aim of this study was to examine perioperative blood transfusion practice, and associations with clinical outcomes, in a national cohort of hip fracture patients. Methods. A retrospective cohort study was undertaken using linked data from the Scottish Hip Fracture Audit and the Scottish National Blood Transfusion Service between May 2016 and December 2020. All patients aged ≥ 50 years admitted to a Scottish hospital with a hip fracture were included. Assessment of the factors independently associated with red blood cell transfusion (RBCT) during admission was performed, alongside determination of the association between RBCT and hip fracture outcomes. Results. A total of 23,266 individual patient records from 18 hospitals were included. The overall rate of blood transfusion during admission was 28.7% (n = 6,685). There was inter-hospital variation in transfusion rate, ranging from 16.6% to 37.4%. Independent perioperative factors significantly associated with RBCT included older age (90 to 94 years, odds ratio (OR) 3.04 (95% confidence interval (CI) 2.28 to 4.04); p < 0.001), intramedullary fixation (OR 7.15 (95% CI 6.50 to 7.86); p < 0.001), and

Aims. This study explores the reported rate of surgical site infection (SSI) after hip fracture surgery in published studies concerning patients treated in the UK. Methods. Studies were included if they reported on SSI after any type of surgical treatment for hip fracture. Each study required a minimum of 30 days follow-up and 100 patients. Meta-analysis was undertaken using a random effects model. Heterogeneity was expressed using the I. 2. statistic. Risk of bias was assessed using a modified Newcastle-Ottawa Scale (NOS) system. Results. There were 20 studies reporting data from 88,615 patients. Most were retrospective cohort studies from single centres. The pooled incidence was 2.1% (95% confidence interval (CI) 1.54% to 2.62%) across ‘all types’ of hip fracture surgery. When analyzed by operation type, the SSI incidences were: hemiarthroplasty 2.87% (95% CI 1.99% to 3.75%) and

Introduction and Aims: The combination of ipsilateral intertrochanteric and femoral shaft fractures is an uncommon pattern associated with high-energy trauma. This retrospective study used self-report measures to evaluate functional outcome of patients sustaining this fracture pattern and compared two common treatment methods. Method: Three patient-based outcome measures, the Short Form-36 (SF-36), Short Musculoskeletal Functional Assessment (SMFA), and Lower Extremity Functional Scale (LEFS) were used to evaluate the functional outcome of twenty-one patients (13 male, mean 46.7 +/− 16.5 years) treated with a reconstruction nail (n=11) or with a

Purpose: The management of comminuted inter trochanteric fracture are a serious and difficult problem. The proper selection of fixation device is must to avoid significant complication in the management of this common fracture. The use of contoured side plate screw attached to the sliding screw plate anchors the comminuted fragments thus gives better stability, compression, early mobility and bony union to this fracture where other implant fails. Material and method: Since 1997 to 2000, 60 comminuted inter trochanteric fracture- age of 67yrs (46–91year) were treated by close/open reduction and internal fixation with 135 dynamic hip screw plate +side screw plate. The side plate is a narrow D.C.P. (4/5 hole) which is contoured to the fl are of greater trochanter proximally and is attached to the sliding screw plate. The proximal holes of side plate hold the comminuted fragment of greater trochanter with cancellous screw above the

Internal fixation is currently the standard of care for Garden I and II femoral neck fractures in the elderly. However, there may be a degree of posterior tilt on the preoperative lateral radiograph above which failure is likely, and primary arthroplasty would be preferred.

This study represents a secondary analysis of data collected in the FAITH trial, an international multicenter randomized controlled trial comparing the
Introduction. We implemented an exhaustive operative and supervision algorithm for surgical treatment of hip fractures primarily based on own previously published literature. The purpose was to improve supervision and reduce the rate of reoperations. Materials and methods. 2000 consecutive unselected patients above 50 years admitted with a hip fracture were included, 1000 of these prospectively after implementation of the algorithm. Demographic parameters, hospital treatment and reoperations within the first postoperative year were assessed from patient records. The algorithm dictated the surgical treatment based on three objective patient parameters: age, new mobility score and fracture classification on pre-operative anterior-posterior and axial radiographs. Intra capsular fractures were treated with two parallel implants, a
Background: Hip fractures are common among the aged population, with high mortality and morbidity rates. It ‘s annual cost in the United States is expected to double by the year 2040 to about 16 billion U.S Dollars. Of those, approximately 50% are inter-trochanteric fractures. Among them, 50 to 60% are categorized as unstable fractures. Unstable intertrochanteric fractures are defined as 1) fractures with comminution of the posteromedial buttress which exceeds a simple lesser trochanteric fragment; 2) fractures with evidence of subtrochanteric fracture lines; and 3) reverse oblique fractures of the femoral neck. Review of the literature reveals large variations in the amount of complications after surgical treatment of unstable intertrochanteric fractures, among various medial institutes. Infection rates winds from fewer than 1% and up to 15% of cases, and reports of cutout events range from % to 20%. Other complications, such as non-unioin, femoral shaft fractures, and painful hardware, are much less common. Purpose: To investigate the rate of complications after surgical treatment of unstable inter-trochanteric fractures, in our department. Method: Retrospective review of 61 patients who were admitted in our department due to unstable intertro-chanteric fractures, after simple falls, between May 2001 to August 2006, and were treated with intramedullary

Few will disagree that the best femoral head that a young patient can have is his or her own, native femoral head. In the active, healthy patient under age 60 with a displaced femoral neck fracture, well-done, timely ORIF presents the best chance of preserving the patient's native femoral head. Arthroplasty is generally reserved for older patients, over age 60, where attempts at ORIF in this setting have demonstrated failure rates over 40%. “Physiologic age” is a somewhat nebulous term that takes into account the health and ambulatory status of the patient. For example, a 52-year-old with end-stage renal failure, severe osteoporosis, and a displaced femoral neck fracture may best be treated with arthroplasty. However, in reality, such situations are quite rare. Recent studies have documented that approximately 80% of young patients with displaced femoral neck fractures treated with ORIF will keep their own femoral head for 10 years after injury. The variables under the surgeon's control include timing of fixation, quality of reduction, accurate implant placement and implant selection, and capsulotomy. All of these variables potentially affect outcomes. Fractures in this young age group are frequently high shear angle (vertical) Pauwels type 3 fractures, and benefit from fixed angle fixation.

We postulate that differences exist in risk factors and hypothesised poorer outcomes in patients with IH. Methods. A single centre, retrospective study of 929 hip fracture patients managed operatively between June 2015 and July 2017 was conducted. Patients’ demographic, anaesthetic and surgical variables were analysed together with outcomes for length of stay (LOS), 30-day re-admissions, and 30-day mortality. Results.

Background. Isolated fracture of the greater trochanter is an uncommon presentation of hip fracture. Traditional teaching has been to manage these injuries nonoperatively, but modern imaging techniques have made it possible to detect occult intertrochanteric extension of the fracture in up to 90% of cases. This study aims to review the investigation and management of greater trochanter fractures in a single major trauma centre. Methods. A retrospective review was completed of patients admitted with greater trochanter fractures. These were matched to cases with 2-part extracapsular fractures. Initial management and clinical outcome was established using electronic notes and radiographs. Mortality and length of stay was calculated for both groups. Results. 85 isolated greater trochanter fractures in 84 patients were identified from 2006–2017. 81/85 patients were treated non-operatively. 78 were mobilised full weight bearing. None required readmission or operation due to fracture displacement. 58 of these patients had cross-sectional imaging with MRI or CT and 15 of those scanned had intertrochanteric extension of the fracture.

Objectives. The Sliding Hip Screw (SHS) is commonly used to treat trochanteric hip fractures. Fixation failure is a devastating complication requiring complex revision surgery. One mode of fixation failure is lag screw cut-out which is greatest in unstable fracture patterns and when the tip-apex distance of the lag screw is > 25 mm. The X-Bolt Dynamic Hip Plating System (X-Bolt Orthopaedics, Dublin, Ireland) is a new device which aims to reduce this risk of cut-out. However, some surgeons have reported difficulty minimising the tip-apex distance with subsequent concerns that this may lead to an increased risk of cut-out. Patients and Methods. We measured the tip-apex distance from the intra-operative radiographs of 93 unstable trochanteric hip fractures enrolled in a randomised controlled trial (Warwick Hip Trauma Evaluation, WHiTE One trial). Participants were treated with either the
Femoral head collapse due to avascular necrosis (AVN) is a relatively rare occurrence following intertrochanteric fractures; however, with over thirty-thousand intertrochanteric fractures per year in England and Wales alone, and an incidence of up to 1.16%, it is still significant. Often patients are treated with a hip fixation device, such as a
The Radiographic Union Score for Hip (RUSH) is an outcome instrument designed to describe radiographic healing of femoral neck fractures. The ability to identify fractures that have not healed is important for defining non-union in clinical trials and predicting patients that likely require additional surgery to promote fracture healing. We sought to determine a RUSH threshold score that defines nonunion at 6-months post-injury. Our secondary objective was to determine if this threshold was associated with increased risk for non-union surgery. A sample of 248 patients with adequate six-month hip radiographs and complete two-year clinical follow-up were analysed from a multi-national hip fracture trial (FAITH). All patients had a femoral neck fracture and were treated with either multiple cancellous screws or a
Radiation exposure is a hazard to orthopaedic surgeons, theatre staff and patients intra-operatively. Obesity is becoming a more prevalent problem worldwide and there is little evidence how a patient's body habitus correlates with the radiation doses required to penetrate the soft tissues for adequate imaging. We aimed to identify if there was a correlation between Body Mass Index (BMI) and radiation exposure intra-operatively. We performed a retrospective review of 75 patients who underwent

We conducted a prospective randomised trial to compare the results of anatomical reduction and medial displacement osteotomy in 127 consecutive patients with unstable intertrochanteric fractures, of whom 109 completed the study. After an average follow-up of 11 months, we found no significant differences in walking ability, social status or failure of fixation in the two groups. Postoperative complication rates and the early mortality rate were not significantly different, but operating time and blood loss were significantly higher in the osteotomy group.

Fractures of the proximal femur at the level of the lesser trochanter (reversed and transverse fracture lines, Evans classification type II, AO classification A3 fractures) are known to have an increased risk of fixation failure. 58 patients with such a fracture were randomised to have the fracture fixed with either an intramedullary nail (220 mm Targon PF nail) or a

Early and safe mobilization remains the mainstay of treatment for the intertrochanteric fractures. Many implants have been used but the intramedullary implants seem to provide maximum stability in unstable fractures. The aim of this study was to compare two intramedullary devices which have different philosophy and modes of action. Between 01.07.2005 to 30.06.2007, 110 patients with trochanteric fractures treated with the intramedullary hip screw (IMHS, Smith &
Nephew) nail and 105 with the ENDOVIS (Citieffe) nail. The data recorded were the fracture’s type, preoperative hemoglobin level, pre-fracture walking ability. Postoperatively were recorded the operative time, the level of hemoglobin on the first day, mobility status, complications and 12 months mortality rate. The results were comparable regarding blood loss, operative time, and mortality rate. However, the rehabilitation and functional outcome were superior in the IMHS group. This probably was attributed to the higher number of complications of the ENDOVIS nail. IMHS is a valuable tool for the treatment of stable intertrochanteric fractures, offering also excellent results in the management of reverse obliquity, comminuted fractures and those with a subtrochanteric extension. Further investigations are necessary to prove which the ideal intramedullary implant is. However, it seems that devices combining the principles of the
The Medoff sliding plate (MSP) is a new device used to treat intertrochanteric and subtrochanteric fractures. There are three options for sliding; either along the shaft or the neck of the femur, or a combination of both. In a prospective series of 108 consecutive displaced intertrochanteric fractures we used combined dynamic compression. The patients were followed clinically and radiologically for one year. All fractures healed during the follow-up period. The only postoperative technical failure was one lag-screw penetration. Combined compression of the MSP gives increased dynamic capacity which reduces the risk of complications. The low rate of technical failure in our series compares favourably with that of the
Osteotomy has been used in the treatment of unstable intertrochanteric hip fractures in an attempt to increase the stability of the fracture fragments. We have assessed this stability in a randomised prospective trial on 100 consecutive patients, all having fixation by an AO dynamic hip screw, comparing anatomical reduction with two types of osteotomy. The groups were similar in terms of age, gender, mental test score, and fracture configuration. There were more failures of fixation in the osteotomy groups, and the operations took longer. We found no clear benefit from osteotomy and therefore recommend anatomical reduction and fixation by a

Introduction. Intracapsular hip fractures in young adults are treated with internal fixation, often as a surgical emergency to reduce the vascular insult to the femoral head.

400 patients with a trochanteric hip fracture were randomised to fixation with either a 220mm long Targon PF (proximal femoral) nail or a Sliding Hip Screw. All surgery was undertaken or supervised by one surgeon. All patients were followed up for a minimum of one year by a blinded observer. The mean age was 82 years (range 27 to 104 years), 20% were male. Mean length of surgery was slightly increased for the nail (44 versus 49 minutes, p=0.002). Fluoroscopic screening time was increased in the nail group (0.3 versus 0.6 minutes, p<
0.0001). Intra-operative complications were more common with the nailing. There was no difference in blood transfusion requirement between groups. Postoperatively there was no difference in the occurrence of medical complications or mortality. Deep wound infection requiring removal of the implant occurred in one case in the SHS group. In addition there were two cases of cut-out, three of plate detachment from the femur and one non-union in the SHS group, requiring secondary surgery. There were only once compilations in the nailed a case of cut-out which required secondary surgery. At follow-up there was no difference in pain scores between groups but there was a tendency to improved mobility in the nailed group (p=0.004). These results suggest that with improved designs and surgical technique, the newer versions of short nails for proximal femoral fractures may not suffer from the complications of the earlier short intramedullary nails. Intramedullary fixation can result in a lower re-operation rate (3.5% versus 0.5%) and improved mobility in comparison to the
The last decade has seen a rise in the use of the gamma nail for managing inter-trochanteric and subtrochanteric hip fractures. Patients with multiple co-morbidities are under high anaesthetic risk of mortality and are usually not suitable for general or regional anaesthesia. However, there can be a strong case for fixing these fractures despite these risks. Apart from aiming to return patients to their pre-morbid mobility, other advantages include pain relief and reducing the complications of being bed bound (e.g. pressure ulcers, psychosocial factors). While operative use of local anaesthesia and sedation has been documented for insertion of extra-medullary femoral implants such as the
We examined the effect of the Gamma nail on strain distribution in the proximal femur, using ten cadaver femora instrumented with six unidirectional strain gauges along the medial and lateral cortices. The femora were loaded to 1800 N and strains were determined with or without distal interlocking screws before and after experimentally created two-part and four-part fractures. Motion of the sliding screw and the nail was also determined. Strain patterns and screw motion were compared with previously obtained values for a
In a prospective, consecutive study we reviewed the results of 32 supracondylar femoral fractures treated by Smith &
Nephew intramedullary supracondylar nailing between January 1996 and October 2002. The mean age of 23 women and nine men was 67 (58 to 89). All fractures were closed. Two patients had associated upper limb fractures. In four cases, fractures occurred around total knee prostheses. Four patients had previously undergone ipsilateral total hip replacement or had had a
Introduction. Total knee arthroplasty is effective for the management of osteoarthritis of the knee. Conventional techniques utilizing manual instrumentation (MI) make use of intramedullary femoral guides and either extramedullary or intramedullary tibial guides. While MI techniques can achieve excellent results in the majority of patients, those with ipsilateral hardware, post-traumatic deformity or abnormal anatomy may be technically more challenging, resulting in poorer outcomes. Computer-assisted navigation (CAN) is an alternative that utilizes fixed trackers and anatomic registration points, foregoing the need for intramedullary guides. This technique has been shown to yield excellent results including superior alignment outcomes compared to MI with fewer outliers. However, studies report a high learning curve, increased expenses and increased operative times. As a result, few surgeons are trained and comfortable utilizing CAN. Patient-specific instrumentation is an alternative innovation for total knee arthroplasty. Custom guide blocks are fabricated based on a patient's unique anatomy, allowing for the benefits of CAN but without the increased operative times or the high learning curve. In this study we sought to evaluate the accuracy of PSI techniques in patients with previous ipsilateral hardware of the femur. Methods. After reviewing our database of 300 PSI total knee arthroplasty patients, 16 were identified (10 male, 6 female) using the Zimmer NexGen Patient Specific Instrumentation System. Fourteen patients included in the study had a preexisting total hip arthroplasty on the ipsilateral side [Figure 1], 1 had a
To investigate if preoperative CT improves detection of unstable trochanteric hip fractures. A single-centre prospective study was conducted. Patients aged 65 years or older with trochanteric hip fractures admitted to Stavanger University Hospital (Stavanger, Norway) were consecutively included from September 2020 to January 2022. Radiographs and CT images of the fractures were obtained, and surgeons made individual assessments of the fractures based on these. The assessment was conducted according to a systematic protocol including three classification systems (AO/Orthopaedic Trauma Association (OTA), Evans Jensen (EVJ), and Nakano) and questions addressing specific fracture patterns. An expert group provided a gold-standard assessment based on the CT images. Sensitivities and specificities of surgeons’ assessments were estimated and compared in regression models with correlations for the same patients. Intra- and inter-rater reliability were presented as Cohen’s kappa and Gwet’s agreement coefficient (AC1).Aims

Hip fracture treatment strategies continue to evolve with the goal of restoring hip fracture victims to Pre-injury Functional levels. Strategies for improved treatment have focused on fracture exposure, reduction, provisional fixation and definitive fixation with implant designs optimised for fracture union with minimal implant failure as originally proposed by Lambotte. Multiple implant designs have been conceived based on perceived inadequacies of previous generational designs. To better understand this evolutionary process, it is necessary to review the predecessors of modern fracture treatment and understand their design concepts and results. It is interesting that the modern era of surgical treatment of hip fractures actually began in 1902, when Dr Royal Whitman advocated the necessity of a closed reduction of adult hip fractures under general anesthesia and stabilisation by hip spica cast. Dr Whitman predicted the evolution of stabilisation by internal fixation and commented on this in his 1932 JBJS editorial emphasising the importance of surgical treatment of fractures. Dr Smith-Peterson, also from New York, in 1925 developed the 1st commercially successful hip implant, a tri–flanged nail. These first surgeries were performed with an open reduction, through a Smith-Petersen approach without radiographic control. This nail device was rapidly modified in the 1930's to permit insertion over a guide wire with a radiographic controlled insertion technique, a minimally invasive procedure. Nail penetration and implant failure in pertrochanteric fractures led to the rapid development of side-plates and a refocus on reduction stability. This led to a period of primary corrective osteotomies for enhanced stability, but fell out of failure after the
There is continuing debate regarding the merits of internal fixation versus arthroplasty for intracapsular hip fractures. For displaced fractures there is a higher risk of fracture healing complications but many of the studies reporting on this are now from some years ago using surgical methods that are now outdated. The aim of our study was to determine the incidence of avascular necrosis (AVN) related to age, gender, displacement and operation delay for a large series of patients with intra-capsular fractures treated with internal fixation using contemporary methods. We prospectively studied 1023 patients, 988 fractures were internally fixed with three cannulated screws and 35 with a
Introduction: The Ionising Radiations Medical Exposure Regulations Act 2000 has established diagnostic reference levels for radiological examinations, however at present there are no national guidelines available for orthopaedic trauma surgery. There may be a role for the introduction of diagnostic reference levels at a local level therefore we studied patient area dose and screening time for orthopaedic trauma operations performed in the Regional Trauma Centre in Northern Ireland. Methods: Retrospectively data was retrieved from written radiography records in the Royal Victoria Hospital, during the period of 1st January 2007 to 31st December 2007 for all orthopaedic trauma cases in which an image intensifier was used. The screening time, patient area dose (PAD), details of the operation, patient age, sex, month of the operation and grade of the operating surgeon (trainee or consultant), were recorded. Results: 1709 cases using image intensifier were reviewed. 137 cases were excluded due to incomplete data. 319 hips were screened for insertion of
A neck of femur fracture is known to be a high risk factor for the development of pressure sores with an associated morbidity, mortality and cost. We have attempted to identify risk factors in these patients for the development of pressure sores. We have analysed prospectively collected data of 4654 consecutive patients (1003 males/3473 females). 3.8% developed pressure sores in the sacral, buttock or heel areas. Patients factors that increased the risk of pressure sores were increased age (82.1 years versus 76.6 years), lower mental test score (5.7 versus 6.7), diabetes mellitus (pressure sore incidence 9.4%), higher ASA score (3.0 versus 2.7) and lower admission haemoglobin concentration (120gms versus 124gms). Those patients with an extracapsular fracture were more likely to develop pressure sores compared to patients with an intracapsular fracture (4.5% versus 3.1%). Being male was not a risk factor. Among surgical factors related to an increased risk was a fall in blood pressure during surgery (5.6%). Patients who underwent a dynamic hip screw were more likely to develop pressure sores (pressure sore incidence 4.7%). Patients with an intracapsular fracture treated with internal fixation were less likely to develop pressure sores in comparison to those fractures treated with a hemiarthroplasty or a

Those patients with an extracapsular fracture were more likely to develop pressure sores compared to patients with an intracapsular fracture (4.5% versus 3.1%). Being male was not a risk factor. While the time interval between fall and admission was not significant, the time interval between admission and surgery was found to be an extremely significant risk factor. A fall in blood pressure during surgery (5.6%) was found to increase risk. Patients who underwent a dynamic hip screw were more likely to develop pressure sores (incidence 4.7%). Patients with an intracapsular fracture treated with internal fixation were less likely to develop pressure sores in comparison to those fractures treated with a hemiarthroplasty or a
Background: A radiological audit of the local use of the Dynamic Hip Screw in extracapsular proximal femur fractures. Study aim: to identify cases of mechanical failure and revision, to determine predictors of fixation failure. Methods: A retrospective radiological review of 567 consecutive cases at Western Australian tertiary hospitals over a 3 year period (2002 – 2004) using the Picture Archive Computer System (PACS). Results: Female: male ratio was 2.79: 1. Evan’s classification: 418 fractures stable (73.7%), 149 unstable (26.3%). Failure of fixation occurred in 14 cases (2.5%); ten due to hip screw cut out (1.8%) and four due to plate pull off (0.8%). All cases of cut out had a significantly higher mean tip apex distance (TAD) (31 vs 20mm, P <
0.001) and an unstable fracture configuration; 8 of 10 had a poor reduction. Bivariate logistical regression revealed TAD of 25mm or more to be most predictive of cut out; followed by mean TAD, superior anterior and inferior posterior screw placement, unstable fracture configuration and poor reduction. Unassociated factors included gender, age, American Society of Anesthesiologists’ score, plate angle and length, operation time and surgeon level. A three-variable model found TAD of 25mm or more and unstable fracture configuration to be predictive, but not poor reduction. Cases with a TAD of 25mm or more with unstable fracture configuration and a poor reduction had a 21.6% chance of cut out (8 of 29). Conclusions: This is the first multifactorial multivariate analysis of a single implant

Introduction:. Total knee arthroplasty (TKA) is an effective operation for the management of osteoarthritis of the knee. Conventional technique utilizing manual instrumentation (MI) allows for reproducible and accurate execution of the procedure. The most common techniques make use of intramedullary femoral guides and either extrameduallary or intrameduallary tibial guides. While these methods can achieve excellent results in the majority of patients, those with ipsilateral hardware, post-traumatic deformity or abnormal anatomy may preclude the accurate use of these techniques. Patient-specific instrumentation (PSI) is an alternative innovation for total knee arthroplasty. Utilizing magnetic resonance imaging (MRI) or computed tomography (CT), custom guide blocks are fabricated based on a patient's unique anatomy. This allows for the benefits of computer assisted navigation (CAN) but without the increased operative times or the high learning curve associated with it. Furthermore it allows the use of familiar cutting blocks and guides to check the accuracy of the PSI guide blocks. In this study we sought to evaluate the accuracy of PSI techniques in patients with previous ipsilateral hardware, which would make the use of MI technically challenging and possibly subject to inaccuracy. Methods:. After reviewing our database of 300 PSI total knee arthroplasty patients, 16 patients were identified (10 male, 6 female) using the Zimmer NexGen Patient Specific Instrumentation System. Fourteen patients included in the study had a preexisting total hip arthroplasty on the ipsilateral side, 1 had a preexisting
Introduction. The
At Bispebjerg University Hospital in Denmark, an Optimized Hip Fracture Program, (OHP) is the standard of care for all hip fracture patients. Part of OHP is pain treatment with a femoral nerve catheter placed at the emergency room, dosed 4 times a day with Bupivacain until 4 days after surgery, combined with systemic analgesics as needed. In 2008, a database and a bio bank were created at the ward including all hip fracture patients to make a better description of the population and as a tool for further optimisation of the OHP. One of the aims was to identify possible subgroups having specific complications, which could lead to a differentiation of the OHP by markers known at the time of admission. In this analysis, we will focus on postoperative pain that inhibits mobilization by fracture type and type of surgery. Methods. A consecutive cohort of 898 hip fracture patients hospitalized within two years from September 2008 to July 2010 was used for this study. Patients coming from nursing homes were excluded from the study, since nearly all are discharged 1 or 2 days after surgery to rehabilitation. If the exact type of fracture was not known, or if the patient was admitted for rehabilitation after surgery at another hospital, the patient was also excluded. 508 patients were thus included in the study. Mean age 80.0 years (SD:23.7), 72.1% women and 27.9% men. Mobilization inhibited by postoperative pain as documented in the patient files was registered in the database. Overall mobilization was inhibited by pain in 26.7% of the 508 patients included. The following fracture types were studied: Femoral neck Garden 1–2, Femoral neck Garden 3–4, Pertrochanteric Evans 1–2, Pertrochanteric Evans 3–5, Basocervical and Subtrochanteric. Results. Mobilization inhibited by pain was not significantly associated with type of surgery:. Cannulated Hip Screws 16/80 (20.0%),

This work aimed at answering the following research questions: 1) What is the rate of mechanical complications, nonunion and infection for head/neck femoral fractures, intertrochanteric fractures, and subtrochanteric fractures in the elderly USA population? and 2) Which factors influence adverse outcomes? Proximal femoral fractures occurred between 1 January 2009 and 31 December 2019 were identified from the Medicare Physician Service Records Data Base. The Kaplan-Meier method with Fine and Gray sub-distribution adaptation was used to determine rates for nonunion, infection, and mechanical complications. Semiparametric Cox regression model was applied incorporating 23 measures as covariates to identify risk factors.Aims

To develop prediction models using machine-learning (ML) algorithms for 90-day and one-year mortality prediction in femoral neck fracture (FNF) patients aged 50 years or older based on the Hip fracture Evaluation with Alternatives of Total Hip arthroplasty versus Hemiarthroplasty (HEALTH) and Fixation using Alternative Implants for the Treatment of Hip fractures (FAITH) trials. This study included 2,388 patients from the HEALTH and FAITH trials, with 90-day and one-year mortality proportions of 3.0% (71/2,388) and 6.4% (153/2,388), respectively. The mean age was 75.9 years (SD 10.8) and 65.9% of patients (1,574/2,388) were female. The algorithms included patient and injury characteristics. Six algorithms were developed, internally validated and evaluated across discrimination (c-statistic; discriminative ability between those with risk of mortality and those without), calibration (observed outcome compared to the predicted probability), and the Brier score (composite of discrimination and calibration).Aims

Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery. This observational cohort study enrolled consecutively admitted patients with a proximal femoral fracture, for which surgery was performed between 1 January 2018 and 11 January 2021 in two level II trauma teaching hospitals. Patients with medical indications to postpone surgery were excluded. A total of 1,803 patients were included, of whom 1,428 had surgery < 24 hours and 375 had surgery ≥ 24 hours after admission.Aims
