Aims. Proximal femur fractures treatment can involve anterograde nailing with a single or double cephalic screw. An undesirable failure for this fixation is screw cut-out. In a single-screw nail, a tip-apex distance (TAD) greater than 25 mm has been associated with an increased risk of cut-out. The aim of the study was to examine the role of TAD as a risk factor in a cephalic double-screw nail. Methods. A retrospective study was conducted on 112 patients treated for intertrochanteric femur fracture with a double proximal screw nail (Endovis BA2; EBA2) from January to September 2021. The analyzed variables were age, sex, BMI, comorbidities, fracture type, side, time of surgery, quality of reduction, pre-existing therapy with bisphosphonate for osteoporosis, screw placement in two different views, and TAD. The last follow-up was at 12 months. Logistic regression was used to study the potential factors of screw cut-out, and receiver operating characteristic curve to identify the threshold value. Results. A total of 98 of the 112 patients met the inclusion criteria. Overall, 65 patients were female (66.3%), the mean age was 83.23 years (SD 7.07), and the mean follow-up was 378 days (SD 36). Cut-out was observed in five patients (5.10%). The variables identified by univariate analysis with p < 0.05 were included in the multivariate logistic regression model were screw placement and TAD. The TAD was significant with an odds ratio (OR) 5.03 (p = 0.012) as the screw placement with an OR 4.35 (p = 0.043) in the anteroposterior view, and OR 10.61 (p = 0.037) in the lateral view. The TAD threshold value identified was 29.50 mm. Conclusion. Our study confirmed the risk factors for cut-out in the double-screw nail are comparable to those in the single screw. We found a TAD value of 29.50 mm to be associated with a risk of cut-out in double-screw nails, when good fracture reduction is granted. This value is higher than the one reported with single-screw nails. Therefore, we suggest the role of TAD should be reconsidered in well-reduced fractures treated with double-screw intramedullary nail. Cite this article: Bone Jt Open 2024;5(6):457–463

Aim. to compare the medium term clinical and functional results of total hip arthroplasty after intertrochanteric osteotomy and primary total hip replacement. Material and methods. We compared 2 groups of patients: Group I-93 patients with total hip arthroplasty after intertrochanteric osteotomy and Group II-93 patients with primary total hip arthroplasty. The patients in the control group (Group II) were randomly chosen from the cases operated by the same surgical team using the same kind of implant like those in Group I. The osteotomies were of different types: medial displacement (27), varisation(19), valgisation (18), flexion(25), rotational (4). The demographic parameters were similar in the 2 groups. Technical intraoperative challenges were noted. The Harris Score was determined at 12 months and 3 years after surgery. Clinical and radiological check-ups were performed each year. The duration of each surgical procedure was recorded. Complications were noted during the entire follow-up. The mean follow-up was 77 months. Results. The average time interval between osteotomy and total hip replacement was 76 months. The average Harris Score (HHS) at 1 year after surgery was 88 in Group I and 93 in Group II. At 3 years, the average values of HHS were 85 in the first group and 92 in the second. After an average follow-up of 6 years, 6 patients in group I (6,45%) required revision arthroplasty, while in the second group this procedure was not necessary. The indication of revision was loosening of the femoral component in 4 cases and of both components in 2 cases. The duration of a total hip arthroplasty after an ostheotomy was almost two times longer than a primary total hip replacement. In most cases, the surgical procedure implicated removal of a blade plate or others fixation devices, reaming of the femur, osteotomies of the greater trochanter, reverse osteotomies of the intertrochanteric region and the use of special design (thin or curved) femoral stems. In group I, intraoperative complications included fractures of the femoral diaphysis, fractures of the greater trochanter, false passage for the femoral component and malposition of the femoral stem. Postoperative complications consist in dislocations, early loosening, heterotopical ossifications, wound sepsis, etc. Conclusions. Total hip arthroplasties after intertrochanteric osteotomies have clinical results a little bit inferior of those of primary total hip replacements, but the difference is not significative. The survival rate of prosthesis implanted after intertrochanteric osteotomies at 6 years is significantly inferior. Both the intraoperative and postoperative complications rates are far superior of those of the primary arthroplasties

Aims. The aim of this study was to investigate the hypothesis that a single dose of tranexamic acid (TXA) would reduce blood loss and transfusion rates in elderly patients undergoing surgery for a subcapital or intertrochanteric (IT) fracture of the hip. Methods. In this single-centre, randomized controlled trial, elderly patients undergoing surgery for a hip fracture, either hemiarthroplasty for a subcapital fracture or intramedullary nailing for an IT fracture, were screened for inclusion. Patients were randomly allocated to a study group using a sealed envelope. The TXA group consisted of 77 patients, (35 with a subcapital fracture and 42 with an IT fracture), and the control group consisted of 88 patients (29 with a subcapital fracture and 59 with an IT fracture). One dose of 15 mg/kg of intravenous (IV) TXA diluted in 100 ml normal saline (NS,) or one dose of IV placebo 100 ml NS were administered before the incision was made. The haemoglobin (Hb) concentration was measured before surgery and daily until the fourth postoperative day. The primary outcomes were the total blood loss and the rate of transfusion from the time of surgery to the fourth postoperative day. Results. Homogeneity with respect to baseline characteristics was ensured between groups. The mean total blood loss was significantly lower in patients who received TXA (902.4 ml (-279.9 to 2,156.9) vs 1,226.3 ml (-269.7 to 3,429.7); p = 0.003), while the likelihood of requiring a transfusion of at least one unit of red blood cells was reduced by 22%. Subgroup analysis showed that these differences were larger in patients who had an IT fracture compared with those who had a subcapital fracture. Conclusion. Elderly patients who undergo intramedullary nailing for an IT fracture can benefit from a single dose of 15 mg/kg TXA before the onset of surgery. A similar tendency was identified in patients undergoing hemiarthroplasty for a subcapital fracture but not to a statistically significant level.

Aims. The aim of this paper is to review the evidence relating to the anatomy of the proximal femur, the geometry of the fracture and the characteristics of implants and methods of fixation of intertrochanteric fractures of the hip. Materials and Methods. Relevant papers were identified from appropriate clinical databases and a narrative review was undertaken. Results. Stable, unstable, and subtrochanteric intertrochanteric fractures vary widely in their anatomical and biomechanical characteristics, as do the implants used for their fixation. The optimal choice of implant addresses the stability of the fracture and affects the outcome. Conclusion. The treatment of intertrochanteric fractures of the hip has evolved along with changes in the design of the implants used to fix them, but there remains conflicting evidence to guide the choice of implant. We advocate fixation of 31A1 fractures with a sliding hip screw and all others with an intramedullary device. Cite this article: Bone Joint J 2017;99-B:128–33

Introduction. Total Hip Arthroplasty (THA) in patients after proximal femoral osteotomy remains a major challenge. Inferior survival for both cementless and cemented THA has been reported in this subgroup of patients. Methods. We retrospectively evaluated the clinical and radiographic results of a consecutive series of 48 THAs (45 Patients) who had undergone conversion THA for failed intertrochanteric osteotomy after a mean of 12 years (2–33 years) using a cementless, grit-blasted, double-tapered femoral stem. Mean follow-up was 20 years (range, 15–25 years), mean age at surgery was 47 years (range, 13–55 years). Clinical results were evaluated using the Harris Hip Score. Kaplan-Meier survivorship analysis was performed to determine long-term outcomes for different end points. Results. At follow-up, 10 patients (11 hips) had died, and 1 patient (1 hip) was lost to follow-up. Five patients (5 hips) underwent femoral revision, 2 for infection and 3 for aseptic loosening of the stem. Overall stem survival was 91% at 20 years (95%-CI: 78%–97%); survival with femoral revision for aseptic loosening as end point was 93% (95%-CI: 80%–98%). Discussion and Conclusion. The long-term results with this type of cementless femoral component in young patients with failed intertrochanteric osteotomy are encouraging and compare well to those achieved in patients with regular femoral anatomy

Objectives

The use of two implants to manage concomitant ipsilateral femoral shaft and proximal femoral fractures has been indicated, but no studies address the relationship of dynamic hip screw (DHS) side plate screws and the intramedullary nail where failure might occur after union. This study compares different implant configurations in order to investigate bridging the gap between the distal DHS and tip of the intramedullary nail.

Introduction

The purpose of the present study was to identify risk factors for lag-screw cut-out following osteosynthesis of intertrochanteric fractures.

Unstable intertrochanteric fractures may be treated by several types of implants, most frequently by dynamic sliding hip screw or some form of intramedullary implant. Intramedullary implants began to be used in cases with an expectation of further improvement of osteosynthesis stability. A need to determine the advantages of single implants for selected types of fractures in randomized trials was defined. In addition to biomechanical principles, bone quality is considered, together with increasing possibilities in recent years of further improving density measurements, especially qCT with respect to local specificity. A series of 86 patients (24 men, 62 women, average age 77,6 years) was operated on from September 6, 2005 to June 30, 2009 for unstable intertrochanteric fracture (31 A2.1, A2.2, A2.3), either by DHS of PFN osteosynthesis after randomization. A CT examination of both hip joints in a predefined manner was performed before surgery. Using special software the relative density of the central spherical part of the femoral head 2 and 3 centimetres in diameter was determined. After fracture healing, the dynamization of the neck screw of both implants and the reduction of vertical distance between the tip of the neck screw and subchondral bone of the femoral head were determined. In addition to evaluation of osteosynthesis stability and osteosyntheis failure, clinical parameters such as surgical time, blood loss and length of hospital stay were compared between the two groups of patients. Survival of patients was evaluated with respect to April 21, 2010. In the patient series, 4 failures of DHS osteosynthesis (cut out) and 2 failures of PFN osteosynthesis (cut out) were noted. Sliding of the DHS was on average 11,9 mm, and was significantly higher in comparison to dynamization of the PFN neck screw, which was 6,9 mm (p=0,005). When comparing the vertical distance between the tip of the neck screw and subchondral bone of the femoral head immediately after surgery and after fracture healing the average reduction of the vertical distance was 1,6 mm in DHS osteosynthesis and 0,8 mm in PFN osteosynthesis. The difference was statistically significant (p=0,025). PFN seems to provide a more stable fixation, based on the measurements. The number of failed DHS osteosyntheses is higher in comparison to the number of failed PFN osteosyntheses but the difference is not statistically significant. The influence of femoral head density on osteosynthesis failure could not be determined due to a low number of failed osteosyntheses in both patient groups. At the same time, after statistical analysis, influence of the relative femoral head density on vertical distance reduction between the screw tip and femoral head subchondral bone in healed fractures was not proven. Statistically, average length of surgical time, length of hospital stay, mean blood loss and survival did not differ significantly between the two patient groups.

Materials and method

This study included 309 patients, over the age of 60 (44 men, 256 women, mean age 85.6 years) who underwent osteosynthesis using a short femoral nail(Gamma)for femoral intertrochanteric fractures. The new reduction classification was defined, in AP view by the degree of contact between the medial cortex of the proximal fragment and that of the medial cortex of the distal fragment. The classification in AP view is divided into three Types: Anatomical Type, Medial Type, and Lateral Type. As for the ML view was defined based on the degree of anterior cortex contact between proximal and distal fragment, was divided also into Anatomical Type, Intramedullary Type, and Extramedullary Type. We assessed lag screw sliding amount at 2 weeks period after surgery as the post-operative displacement.

Aims. Osseointegrated prosthetic limbs allow better mobility than socket-mounted prosthetics for lower limb amputees. Fractures, however, can occur in the residual limb, but they have rarely been reported. Approximately 2% to 3% of amputees with socket-mounted prostheses may fracture within five years. This is the first study which directly addresses the risks and management of periprosthetic osseointegration fractures in amputees. Methods. A retrospective review identified 518 osseointegration procedures which were undertaken in 458 patients between 2010 and 2018 for whom complete medical records were available. Potential risk factors including time since amputation, age at osseointegration, bone density, weight, uni/bilateral implantation and sex were evaluated with multiple logistic regression. The mechanism of injury, technique and implant that was used for fixation of the fracture, pre-osseointegration and post fracture mobility (assessed using the K-level) and the time that the prosthesis was worn for in hours/day were also assessed. Results. There were 22 periprosthetic fractures; they occurred exclusively in the femur: two in the femoral neck, 14 intertrochanteric and six subtrochanteric, representing 4.2% of 518 osseointegration operations and 6.3% of 347 femoral implants. The vast majority (19/22, 86.4%) occurred within 2 cm of the proximal tip of the implant and after a fall. No fractures occurred spontaneously. Fixation most commonly involved dynamic hip screws (10) and reconstruction plates (9). No osseointegration implants required removal, the K-level was not reduced after fixation of the fracture in any patient, and all retained a K-level of ≥ 2. All fractures united, 21 out of 22 patients (95.5%) wear their osseointegration-mounted prosthetic limb longer daily than when using a socket, with 18 out of 22 (81.8%) reporting using it for ≥ 16 hours daily. Regression analysis identified a 3.89-fold increased risk of fracture for females (p = 0.007) and a 1.02-fold increased risk of fracture per kg above a mean of 80.4 kg (p = 0.046). No increased risk was identified for bilateral implants (p = 0.083), time from amputation to osseointegration (p = 0.974), age at osseointegration (p = 0.331), or bone density (g/cm2, p = 0.560; T-score, p = 0.247; Z-score, p = 0.312). Conclusion. The risks and sequelae of periprosthetic fracture after press-fit osseointegration for amputation should not deter patients or clinicians from considering this procedure. Females and heavier patients are likely to have an increased risk of fracture. Age, years since amputation, and bone density do not appear influential.

Aims

To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome.

Aims

This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality.

Aims. We aimed to characterise the effect of expeditious hip fracture surgery in elderly patients within 24 hours of admission on short-term post-operative outcomes. Patients and Methods. Patients age 65 or older that underwent surgery for closed femoral neck and intertrochanteric hip fractures were identified from the American College of Surgeons National Surgical Quality Improvement Program between 2011 and 2014. Multivariable propensity-adjusted logistic regressions were performed to determine associations between early surgery within 24 hours and post-operative complications, controlling for selection bias in patients undergoing early surgery based on observable characteristics. Results. A total of 26 051 patients were included in the study; 5921 (22.7%) had surgery within 24 hours of admission, while 20 130 (77.3%) patients had surgery after 24 hours. Propensity-adjusted multivariable logistic regressions demonstrated that surgery within 24 hours was independently associated with lower odds of respiratory complications including pneumonia, failure to extubate, or reintubation (odds ratio (OR) 0.78, 95% confidence interval (CI) 0.67 to 0.90), and extended length of stay (LOS) defined as ≥ 6 days (OR 0.84, 95% CI 0.78 to 0.90). Conclusion. In elderly patients with hip fractures, early surgery within 24 hours of admission is independently associated with less pulmonary complications including pneumonia, failure to extubate, and reintubation, as well as shorter LOS.

Aims

Patients with A1 and A2 trochanteric hip fractures represent a substantial proportion of trauma caseload, and national guidelines recommend that sliding hip screws (SHS) should be used for these injuries. Despite this, intramedullary nails (IMNs) are routinely implanted in many hospitals, at extra cost and with unproven patient outcome benefit. We have used data from the National Hip Fracture Database (NHFD) to examine the use of SHS and IMN for A1 and A2 hip fractures at a national level, and to define the cost implications of management decisions that run counter to national guidelines.

Aims

Hip fracture commonly affects the frailest patients, of whom many are care-dependent, with a disproportionate risk of contracting COVID-19. We examined the impact of COVID-19 infection on hip fracture mortality in England.

Aims

We assessed the value of the Clinical Frailty Scale (CFS) in the prediction of adverse outcome after hip fracture.

Introduction. The rising incidence of metastatic bone disease (MBD) in the UK poses a significant management problem. Poorly defined levels of service provision have meant that improvements in patient prognosis have been mediocre at best. For that reason the British Orthopaedic Association (BOA) in conjunction with the British Orthopaedic Oncology Society (BOOS) issued guidelines in 2002 on good practice in the management of MBD. Despite the availability of these standards, there is very little robust data available for audit. The aim of this study was to conduct a regional survey of how these guidelines are being used in the management of MBD. Methods. A questionnaire was designed with 9 multiple choice questions representing the most common MBD scenarios. This was posted to 106 Consultant Orthopaedic Surgeons in 12 NHS Trusts in the South East of England. Results. The overall response rate to the questionnaire was 44%. There was considerable variation in the management of solitary femoral diaphyseal lesions, pathological subtrochanteric and intertrochanteric femoral neck fractures and vertebral metastases. Furthermore only 2 out of the 12 Trusts surveyed had a designated MBD lead as per the BOA/BOOS guidelines. Discussion. Our study reflects the variation in the management of MBD throughout the region, which may in turn be linked to poorer clinical outcomes. The results demonstrate the possibility of (i) inappropriate initial treatment, (ii) subsequent late tertiary referral and (iii) poor understanding of the biomechanical basis of orthopaedic implants, with the potential for inappropriate choice of prostheses and high failure rates. Streamlining cancer care will involve establishing regional MBD units within large centres where multidisciplinary services are available. Consequently all surrounding hospitals will need a designated MBD lead that can function as a conduit to this integrated care for selected patients

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 sliding hip screw or the Gamma nail but randomised trials comparing the MSP with other hip screw systems are necessary to find the true role of the MSP with its various sliding modes

Background. Hip fractures affect annually over 350,000 people in the USA and over 1.6 million worldwide. About 50% of these numbers are intertrochanteric fractures,. The surgeon should be able to minimize the morbidity associated with the fracture by: recognizing the fracture pattern, choosing the appropriate fixation device, performing accurate reductions with ideal implant placement and being conscious of implant costs. In this study we assessed the ability of the orthopaedic surgeons to recognize fractures pattern, and choosing the ideal implant for the recognized fracture. Methods. We assessed 134 orthopaedic surgeons with questionnaires that assessed 14 different intertrochanteric femoral fractures. We evaluated the fractures as stable or unstable. We chose for each fracture the appropriate fixation device: either a Dynamic Hip Screw (for stable fractures) or an Intra Medullary Nail (for unstable ones), taking into consideration fracture's stability and implants’ costs. We compared the answers of the assessed surgeons to ours. Results. 134 orthopaedic surgeons fulfilled our questionnaires. The average agreement among the assessed surgeons and the authors for fractures’ stability distributed as follows: 78.2% agreement for the stable fractures, 86.2% for the unstable fractures. The agreement for the appropriate fixator between both groups (authors and surgeons) distributed as follows: in choosing the dynamic hip screws for the stable fractures 79.6% agreed with our choice. When choosing the Intra Medullary Nail for the unstable fractures 72.4% of the surgeons agreed with our choice. Interestingly, surgeons that their subspecialty is orthopaedic trauma tended to use more the Intra Medullary Nails in the stable fractures compared to the other surgeons. Conclusions. The majority of the assessed surgeons know to recognise inertrochanteric fractures’ stability and to choose the appropriate fixation device. 20% of surgeons did not agree with our choices. Choosing an Intra Medullary Nail for the stable fracture is not a mistake, but the wrong fixation device for the unstable fracture may cause non-union, mal-union or hardware failure, and might complicate patients’ rehabilitation and cure. We believe that a team discussion should take place for each and any case before operation, and whenever there is a doubt about fractures stability, the Iintra Medullary Nail should be chosen

Introduction. Unstable intertrochanteric hip fractures (AO 31A2) continue to be a challenge, as non-locking implants have shown a considerable rate of loss of reduction. Intramedullary fixation has been recommended, although screw cut-out has been identified as problematic. This study was performed to ascertain whether treatments with the established proximal femoral nail (PFN) and the newer PFNA with blade design (proximal femoral nail antirotation) have advantages over the use of the Percutaneous Compression Plate (PCCP, developed by Gotfried). Methods. Cohort study. Between March 2003 and March 2008, 134 patients with unstable fractures were treated with a PCCP, (n=44, 78.3 yrs, ASA 2.8), a PFN (n=50, 77.2 yrs, ASA 2.8), or a PFNA (n=40, 75.8 yrs, ASA 2.6). The patients (31 PCCP, 33 PFN, 30 PFNA) were then reexamined clinically and radiologically after approximately 21 months. Results. The PCCP was found to require less implantation time than the PFN and the PFNA (60 vs. 80 vs. 84 min, p<0.001) and less radiation exposition time (PCCP 139 vs. PFN 283 vs. PFNA 188 seconds, p<0.001). The rate of reoperations due to wound infections and hematomas amounted to 2% for the PCCP, 4% for the PFN, and 5% for the PFNA (p=0.799). Due to mechanical complications, 9% of patients implanted with a PCCP, 13% of those implanted with a PFN, and 5% of those implanted with a PFNA had to be reoperated (p=0.353). The cut-out rate was 2% after implantation of the PCCP, 4% after the PFN, and 5% after implantation of the PFNA (p=0.799). In one case, the shaft was fractured intraoperatively (PFNA). The tip-apex distance for the lower femoral neck screw (PCCP 22mm vs. PFN 30mm vs. PFNA 30mm, p<0.001), stress-related varisation of the collodiaphyseal (CCD) angle (4° for all implants), impaction (PCCP 5mm vs. PFN 5mm vs. PFNA 6mm, p=0.662) and femoral shortening (PCCP 3mm vs. PFN 3mm vs. PFNA 4mm, p=0.876) were not determinants of the postoperative function. On the basis of their scores according to Merle d'Aubigné and Harris, there was no variation in the results of the follow-up examinations. Conclusions. The use of the PCCP for the treatment of unstable trochanteric fractures presents a minimally invasive method of implantation, as well as a promising therapy option with regards to operation time, radiologic examination time, and rate of complications. Processes of impaction due to stress are seldom observed. No benefits could be established in an intramedullary treatment with the PFN or the PFNA; thus, it appears that the higher cost of these implants is avoidable
