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

To conduct a meta-analysis for intertrochanteric hip fractures comparing in terms of efficacy and safety short versus long intralomedullary nails. A pubmed search of the last 10 years for intertrochanteric fracture 31A1-31A3 according to the AO/OTA classification was performed. Baseline characteristics of each article were obtained, complication measures were analyzed: Peri-implant fracture, reoperations, deep/superficial infection, and mortality. Clinical variables consisted of blood loss (mL), length of stay (days), time of surgery (min) and nº of transfusions. Functional outcomes were also recorded. A meta-analysis was performed with Review Manager 5.4. Twelve studies were included, nine were retrospective. The reoperations rate was lower in the short nail group and the peri-implant fracture rate was lower in the long nail group (OR 0.58, 95% CI 0.38 to 0.88) (OR 1.88, 95% CI 1.04 to 3.43). Surgery time and blood loss was significantly higher in the long nail group (MD −12.44, 95% CI −14.60 to −10.28) (MD −19.36, 95% CI −27.24 to −11.48). There were no differences in functional outcomes. The short intramedullary nail has a higher risk of peri-implant fracture; however, the reoperation rate is lower compared to the long nail. Blood loss and surgery time was higher in the long nail group

Aims. We compared the clinical outcomes of curved intertrochanteric varus osteotomy (CVO) with bone impaction grafting (BIG) with CVO alone for the treatment of osteonecrosis of the femoral head (ONFH). Methods. This retrospective comparative study included 81 patients with ONFH; 37 patients (40 hips) underwent CVO with BIG (BIG group) and 44 patients (47 hips) underwent CVO alone (CVO group). Patients in the BIG group were followed-up for a mean of 12.2 years (10.0 to 16.5). Patients in the CVO group were followed-up for a mean of 14.5 years (10.0 to 21.0). Assessment parameters included the Harris Hip Score (HHS), Oxford Hip Score (OHS), Japanese Orthopaedic Association Hip-Disease Evaluation Questionnaire (JHEQ), complication rates, and survival rates, with conversion to total hip arthroplasty (THA) and radiological failure as the endpoints. Results. There were no significant differences in preoperative and postoperative HHS or postoperative OHS and JHEQ between the BIG group and the CVO group. Complication rates were comparable between groups. Ten-year survival rates with conversion to THA and radiological failure as the endpoints were not significantly different between groups. Successful CVO (postoperative coverage ratio of more than one-third) exhibited better ten-year survival rates with radiological failure as the endpoint in the BIG group (91.4%) than in the CVO group (77.7%), but this difference was not significant (p = 0.079). Conclusion. Long-term outcomes of CVO with BIG were favourable when proper patient selection and accurate surgery are performed. However, this study did not show improvements in treatment results with the concomitant use of BIG. Cite this article: Bone Joint J 2021;103-B(4):665–671

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

Introduction: Isolated greater trochanter fractures gained clinical importance because of the possibility of their inter-trochanteric extension. Aim: To assess whether the direction and the extent of the fracture measured on plain radiographs could be used to predict the inter-trochanteric extension. Materials and Methods: We reviewed plain radiographs and MRI scans of 24 patients who sustained isolated greater trochanter fractures between year 2003 and 2006. We considered two parameters. extent of fracture in percentage along the intertrochanteric line. angle of the fracture line. Both these parameters were measured on a plain anteroposterior radiograph. To measure the length of fracture we have drawn a straight line along the medial border of femoral shaft extending proximally in to the pelvis. Then we measured the distance between the most superior point of the fracture line on the lateral cortex and the midpoint of lesser trochanter on the first line. Then we measured the length of the fracture starting from the most superior point on the lateral cortex. We estimated the percentage of this fracture length in relation to line. To estimate the angle, again we have drawn a straight line along the medial border of femoral shaft extending proximally in to the pelvis. We have drawn another line in the direction of fracture staring from most superior point of fracture on the lateral cortex joining the first line. We measured the angle between these two lines (Fig 2). We used our Hospital PACS system to measure the angles and the length of the fracture. Results: Out of 24 isolated greater trochanteric fractures as diagnosed by plain radiographs, MRI scans revealed intertrochanteric extension in nine (37.5%). On the plain anteroposterior radiograph, the mean angle of the fracture in those with MRI proven intertrochanteric extension was 34º (range 20º–45º). In those with no intertrochanteric extension on MRI scan, the mean angle was 55º (Range 25º–125º). The mean percentage of length of fracture across the intertrochanteric line was 62% (47%–73%) and 40% (27%–62%) respectively. All the fractures with MRI proven intertrochanteric extension had a fracture angle of < 45º and the percentage of fracture length of > 40%. All the 15 fractures with fracture angle more than 45º did not show intertrochanteric extension on MRI scan. Conclusions: We conclude that those isolated greater trochanteric fractures, with fracture angle of more than 45 º are unlikely to have an intertrochanteric extension. These patients could be mobilised without further MRI scans. Those fractures which fulfil the plain radiographic criteria of extension of more than 40% and fracture angle between 20º–40º are likely to show inter trochanteric extension. These patients need further clinical assessment and MRI scans to confirm the intertrochanteric extension

Introduction. Osteonecrosis of the femoral head occurs in young patients. The preservation of the hip joint is vitally important, because hip arthroplasty does not guarantee satisfactory long-term results in young and active patients. Curved intertrochanteric varus osteotomy is one of several joint preserving procedures used for this disease. Methods. Between June 2004 and June 2007, 52 patients (55 hips) who had osteonecrosis of the femoral head were treated with curved intertrochanteric varus osteotomy. There were 29 men and 23 women who had a mean age at the time of osteotomy of 33 years (range, 18 to 52 years). The osteotomy was fixed with a 120 degree compression hip screw in the first 34 hips and with a 95 degree dynamic condylar screw in the remaining 21 hips. Clinical evaluation was performed using the scoring system of Merle d'Aubigne et al. Results. The mean duration of follow-up was 32 months (range, 24 to 60 months). Six patients (six hips) required a total hip arthroplasty, due to loss of fixation in two hips, shortening of the operated limb in two hips, and further collapse with persistent pain in two hips. In two patients (two hips), the plate fractured at 3 and 4 months after the operation, which was changed to a new plate. Thus, 49 of the 55 hips survived at a mean follow-up 32 months. In these hips, the mean Merle d'Aubigne hip score was 17.4 points at the latest evaluation. Conclusion. Curved intertrochanteric varus osteotomy is a satisfactory joint preserving method to treat osteonecrosis of the femoral head

Aims: To describe a new, simple method of classiþcation for ossiþcations after total hip arthroplasty situated in the anterior, intertrochanteric area. (ÒAIOÒ). Methods: Axial (ÒLauensteinÒ) radiographs of 209 patients after THA using the transgluteal approach were retrospectively analysed regarding the occurrence AIO. These formations are situated in the anterior intertrochanteric region, therefore the major part of these ossiþcations cannot be identiþed by the well known and accepted methods of e.g. Brooker which rely on one anterior-posterior radiograph. By dividing the anterior intertrochanteric region in zones a simple method of classiþcation was developed. According to our method AIO can be classiþed by their appearance and their extent: Grade I describes bony islands without connection to the femoral bone, Grade II ossiþcations are clip or shield like formations without connection to the femoral bone, Grade III ossiþcations appear as solid exostoses in contact with the femoral bone. Results: 97 of 209 patients developed an AIO (48,4%), 12 ossiþcations were classiþed as Grade I (12,4%),3 ossiþcations were classiþed as grade II (3,1%), 82 out of 209 patients developed an AIO Grade III. 27 (13%) of the patients developed solid ossiþcations situated strictly in the anterior intertrochanteric region, thus solely veriþable by an axial radiograph. Conclusions: In our patient collective 13% developed a solid ossiþcation only veriþable by an axial radiograph due to a strictly anterior intertrochanteric location. By using the well accepted methods of classiþcation relying only on one single ap radiograph (Brooker, Arcq, deLee) these formations would not have showed up in our study. Our method of classiþcation is simple and can be easily combined with the classiþcations mentioned above

The knowledge of actual extent of the fracture in cases of isolated greater trochanteric fractures has paramount importance in decision-making. MRI has been the most common investigation to detect the intertrochanteric extension. However, to date there is no plain radiographic or MRI criteria to decide which fractures need surgery and which could be managed non-operatively. The aim of our study-was to assess whether the angle and the extent of the greater trochanteric fracture measured on plain radiographs could be used to predict the intertrochanteric extension. We reviewed plain radiographs of 23 patients with isolated greater trochanteric fractures who also had MRI scans. We considered two parameters. extent of fracture in percentage along the intertrochanteric line and. angle of the fracture line. We compared these plain radiographic findings with those of MRI scans and established plain radiographic criteria to predict intertrochanteric extension. Out of 23 patients, MRI scans revealed intertrochanteric extension in eight and they underwent surgical stabilisation. All these eight fractures had a fracture angle of 45° or less and the percentage of fracture extent of > 40%. All the 15 fractures with a fracture angle of > 45° did not show intertrochanteric extension on MRI scan. The mean angle of the fracture in those with MRI proven intertrochanteric extension was 33.5° (range 20°–45°) and in those with no intertrochanteric extension was 55.7° (Range 25°–125°). The mean percentage of length of fracture across the intertrochanteric line was 61.1% (47%–73%) and 39.6% (27%–62%) respectively. We conclude that those isolated greater trochanteric fractures, with a fracture angle of more than 45° are unlikely to have an intertrochanteric extension. Those fractures with an extent of more than 40% and fracture angle less than 45° are likely to show inter trochanteric extension

Introduction. Curved varus intertrochanteric osteotomy of the femur is an excellent and minimally invasive method for the treatment of osteonecrosis of the femoral head or osteoarthritis of the hip for joint preservation. However, the early postoperative complications of this procedure may be due to separation at the osteotomy site and an increase in varus angle due to early partial weight bearing. Methods. We modified the curved varus intertrochanteric osteotomy of the femur by performing an additional rotation. Regarding the surgical technique, curved varus osteotomy is performed at an angle of 30 degrees to the femoral shaft and an additional rotational osteotomy is also performed at an angle of 15 or 20 degrees to the osteotomy plane. Partial weight bearing with one-third body weight is permitted 3 weeks after surgery. Results. Curved varus intertrochanteric osteotomy of the femur was designed for developmental dysplastic hip by Nishio in 1969 and reported to have good outcomes in 1971. An important feature of this method is that the incidence of high riding of the greater trochanter or shortening of leg length is less than that in varus intertrochanteric osteotomy. Moreover, good contact at the osteotomy site and less lateral shift of the femoral shaft is observed. However, we have experienced a case of separation at the osteotomy site and increase of the varus angle in our hospital. Previous reports recommended that partial weight bearing with one-third body weight should be initiated after 5 weeks and full weight bearing after 6 months because the contact area is decreased at the osteotomy site by varus osteotomy. The post-operative recovery of the patients with total hip arthroplasty is rapid, therefore, we must consider important issues such as initiating the rehabilitation program early and reducing the duration of hospitalization. As per our experience, we think that partial weight bearing with one-third body weight should be initiated at 3 weeks. At the osteotomy site, we rotated the nearest bone segment to move it such that it intersects the proximal and distal bone cortex. Therefore, the osteotomy site will be stabilized and will have the ability to endure load. Another feature of this technique is that the partial removal of the necrotic area leads to an increase in the healthy load-bearing area. A limitation of this method is that an angle of an additional rotation is up to 30 degrees, because the joint capsule cannot be incised circumferentially and the short external rotator tendons should also be preserved. Conclusion. Modified curved varus intertrochanteric osteotomy is a useful method for the prevention of increased degree of a varus angle as well as for obtaining more intact area of femoral head in osteonecrosis

Intertrochanteric fractures are common, accounting for nearly 30% of all fracture related admissions. Some have suggested that these fractures should be treated in community hospitals so as not to tax the resources of Level One trauma centers. Since many factors predictive of fixation failure are related to technical aspects of the surgery, the purpose of this study was to compare radiographic parameters after fixation comparing trauma fellowship trained surgeons to non-fellowship trained community surgeons to see if these fractures can be treated successfully in either setting. Using our hospital system's trauma database, we identified 100 consecutive patients treated with cephalomedullary nails by traumatologists, and 100 consecutive patients treated by community surgeons. Quality of reduction, neck shaft angle (NSA), tip-to apex distance (TAD) were compared. The mean TAD for the trauma group was 10mm compared to 21mm for the community group (p<0.001). The mean postoperative NSA for the trauma group was 133 degrees compared to 127 degrees for the community group (p<0.001). The mean difference in the NSA of the fractured side compared to the normal hip was 2.5 degrees of valgus in the trauma group compared to 5 degrees of varus for the community group (p<0.001). There were 93 good reductions in the trauma group compared to 19 in the community group (p<0.001). There were no poor reductions in the trauma group and 49 poor reductions in the community group (p<0.001). Fellowship trained traumatologists achieved significantly more accurate reductions and implant placement during cephalomedullary nailing of intertrochanteric hip fractures

The benefit of using a long intramedullary device for the treatment of geriatric intertrochanteric hip fractures is unknown. The InterTAN device (Smith and Nephew, Memphis TN) is offered in either Short (180–200 mm) or Long (260–460 mm) constructs and was designed to provide stable compression across primary intertrochanteric fracture fragments. The objective of our study was to determine whether Short InterTANs are equivalent to Long InterTANs in terms of functional and adverse outcomes for the treatment of geriatric intertrochanteric hip fractures. 108 patients with OTA classification 31A–1 and 31A–2 intertrochanteric hip fractures were included in our study and prospectively followed at one of four Canadian Level-1 Trauma Centres. Our primary outcomes included two validated primary outcome measures: the Functional Independence Measure (FIM), to measure function, and the Timed Up and Go (TUG), to measure motor performance. Secondary outcome measures included blood loss, length of procedure, length of stay and adverse events. A pre-injury FIM was measured by retrospective recall and all postoperative outcomes were assessed on postoperative day 3, at discharge, at 6 weeks, 3 months, 6 months and 12 months postoperatively. Unpaired t-tests and Chi-square tests were used for the comparison of continuous and categorical variables respectively between the Short and Long InterTAN groups. A statistically significant difference was defined as p<0.05. Our study included 71 Short InterTAN and 37 Long InterTAN patients with 31A–1 and 31A–2 intertrochanteric hip fractures. Age, sex, BMI, side, living status and comorbidities were similar between the two groups. The mean operative time was significantly lower in the Short InterTAN group (61 mins) as compared to the Long InterTAN group (71 mins)(p0.05). There were 5 periprosthetic femur fractures in the short InterTAN group versus 1 in the long InterTAN group. Non-mechanical adverse outcomes such as myocardial infarction, pulmonary embolism, urinary tract infections, pneumonia and death all had similar incidence rates between the two InterTAN groups. Both the Short and Long InterTAN patient cohorts displayed similar improvements in performance and overall function over the course of a year following intertrochanteric hip fracture fixation. The recorded operative times for Short InterTAN fixation were significantly shorter than those recorded for the Long InterTAN patients. Alternatively, a significantly higher proportion of Short InterTAN patients sustained periprosthetic femur fractures within a year of implantation as compared to the Long InterTAN group

Introduction: In postmenopausal female patients with hip osteoarthritis, osteoporosis as well as altered local trabecular bone architecture may lead to a increased migration of uncemented hip prostheses. 1. ,. 2. The aim of this study was to determine whether 3D bone architecture and mechanical properties of intertrochanteric cancellous bone in the proximal femur predict RSA migration of uncemented femoral stems. Materials and Methods: The study population consisted of 61 female patients with primary hip osteoarthritis. Informed consent was obtained prior to any study-related procedures. The Ethical Committee approved the study protocol. All patients underwent a total hip replacement (ABG II, Stryker) with uncemented proximally hydroxyapatite-coated femoral stem with tantalum RSA markers. Ceramicceramic bearing surfaces were used. A uniplanar type of RSA setup was applied. The RSA examinations were performed postoperatively and at 3, 6, and 12 months. During surgery, cancellous bone biopsy was taken from the proximal femur from the site of stem implantation. The specimens were scanned with micro-CT. 3D analysis of trabecular bone geometry and BMD was performed using CTAn software. After micro-CT imaging, the trochanteric cancellous bone specimens were subjected to a destructive compression test. Maximum force and stiffness were calculated. Linear regression analysis was applied to study correlations between different parameters investigated. Results: The patients exhibited major differences in the density and structural quality of intertrochanteric cancellous bone. Significant correlations were found between the measured biomechanical parameters and the structural parameters calculated from micro-CT data. Unexpectedly, the quality of intertrochanteric cancellous bone did not predict RSA migration of the femoral stems. The femoral stems reached high stability within 3 months and there were no significant differences in the axial and rotational migration of the femoral stems between the patients with normal or poor quality of the intertrochanteric cancellous bone. Discussion: The 3D bone architecture, mineral density and mechanical properties of the local intertrochanteric cancellous bone do not seem to serve as predictors of femoral stem migration. The observation suggests that the significance of cancellous bone quality for the initial stability of uncemented femoral stems has been over-emphasized

Introduction: Osteonecrosis of the femoral head occurs in young patients. The preservation of the hip joint is vitally important because hip replacement arthroplasty is associated with high rates of failure in young and active patients. Curved intertrochanteric varus osteotomy is one of several joint preserving procedures used to treat these patients. Methods: Between June 2003 and June 2006, 46 patients (49 hips) who had osteonecrosis of the femoral head were treated with curved intertrochanteric varus osteotomy. There were 23 men and 23 women who had a mean age at the time of osteotomy was 33 years (range, 17 to 51 years). The osteotomy was fixed with a 120 degree compression hip screw in the first 34 hips and with a 95 degree dynamic condylar screw in the remaining 15 hips. Clinical evaluation was performed using the scoring system of Merle d’Aubigne et al. Radiological failure of the operation was defined as further collapse of the femoral head by more than 2 mm or progressive narrowing of the joint space compared with the immediate postoperative radiograph. Results: The mean duration of follow-up was 22 months (range, 12 to 48 months). One patient (one hip) required a total hip arthroplasty due to loss of fixation and penetration of the lag screw into the joint space. In two patients (two hips), the plate fractured at 3 and 4 months after the operation, which was changed to a new plate. Thus, 48 of the 49 hips survived at a mean follow-up 22 months. In these 48 hips, the mean Merle d’Aubigne hip score was 17.2 points at latest evaluation and there was no instance of radiologic failure. Discussion: Curved intertrochanteric varus osteotomy is a satisfactory joint preserving method to treat osteonecrosis of the femoral head

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 sliding hip screw and retrograde nail (n=10). Results: Mechanisms of injury included motor vehicle accidents (66.7%) and falls from height (14.3%). SF-36 physical and mental component scores were less than Canadian norms, with mean values of 35.9 (p=0.0001) and 43.7 (p=0.02), respectively. There was a trend towards better functional outcome in the group treated with the sliding hip screw with retrograde nail despite this group sustaining more severe injuries as measured by ISS (p=0.004), number of days in hospital (p=0.027), and number of days in ICU (p=0.009). Conclusion: Functional outcome following treatment of ipsilateral intertrochanteric and femoral shaft fractures was reduced compared to Canadian norms. Despite having sustained more severe injuries, the sliding hip screw with retrograde nail group showed a trend towards better outcome as compared to the group treated with the reconstruction nail

Purpose: The results of surgical treatment of intertrochanteric hip fractures using a sliding hip screw-plate and Norian-SRS, as an adjuvant means of stabilization, are presented. Material – Methods: 103 patients (27 male, 76 female) with intertrochanteric hip fractures, were treated with a sliding hip screw. Their age ranged from 56 to93 years (av. 68,9y) . In group A (50 patients) we only used a sliding hip screw -plate, while in group B ( 53 patients) we also used Norian-SRS above the upper surface of the sliding hip screw. Results: Postoperative follow-up ranged from 5 to17 μnνϵς. Mobilization was initiated on the 2nd day with partial weight bearing. A group progressed to full weight bearing in 3 , while B group in 2 months. 8 patients in group A and 2 in group B developed varous deformity. Screw cut out developed in 5 patient of group A and none of group B. Backsliding of the screw ranged from 0 to 16 mm. (av. 4,95 mm.) in group A and from 0 to16mm. (av. 3,25mm.) in group B. Conclusion: Norian-SRS augmentation of intertrochanteric hip fractures treated with a sliding hip screw-plate, increases the stability of the osteosynthesis, permitting earlier rehabilitation and mobilization of the patient and leading to better functional results

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

Introduction. Cephalomedullary nails (CMN) are commonly used for the treatment of intertrochanteric (IT) hip fractures. Total hip arthroplasty (THA) is commonly used as a salvage procedure for failed IT hip fractures that progress to post-traumatic arthritis. This study analyzed the complications of THA following treatment of failed IT hip fractures with cephalomedullary nails. Methods. Patients who had a primary THA were identified from the 5% subset of Medicare Parts A/B from 2002–2015. A subgroup with previous CMN for IT hip fracture within the previous 5 years was identified and compared to the remaining THA patients without prior CMN. Length of stay (LOS) was compared using both univariate and multivariate analysis. Infection, dislocation, revision, and readmission were compared between those with and without prior CMN, using multivariate analysis (adjusted for demographic, hospital, and clinical factors). Results. 5% subset of the Medicare data yielded 56,522 primary THA, with 369 treated with prior CMN. The percentage of primary THA from 2002–2005 with prior cephalomedullary nails (0.346%) more than doubled in 2012–2015 (0.781%). The prior CMN group tended to be older, female, higher CCI, and lower socioeconomic status. Mean LOS was 1.5 days longer (5.3 vs 3.8) in the prior CMN group (p<0.0001). The percentage of postoperative complications was significantly higher in the prior CMN group compared to non-CMN cohort: infection (6.2% vs 2.6%), dislocation (8.1% vs 4.5%), revision (8.4% vs 4.3%), revision for infection (1.1% vs 0.37%), and revision for dislocation (2.2% vs 0.6%). Discussion. Conversion from failed IT hip fractures with cephalomedullary nails to total hip arthroplasty continues to increase. These cases occur in elderly patients with increased comorbidities. There is a significantly increased risk of infection, dislocation and LOS in the CMN group. Patients with failed IT hip fractures undergoing THA should be made aware of the increased complication risk and further steps need to be undertaken to diminish the elevated risk

Aims: In younger patients with dysplastic hip we come to the polemic Ð THR or joint-saving operation? The purpose of this presentation is to introduce the indications and the results of joint-saving operations as performed at our department. Methods: We analyzed patients with dysplastic hip, who undergone a joint-saving surgery at our department in past years 1997 Ð 2002. As those were younger patients, we indicated osteotomy Ð Chiari, Salter, Dega as well as pelvic osteotomy with the use of bone allograft. In all the patients we also performed a debridement and intertrochanteric osteotomy. In patients with signs of femoral head necrosis we performed transtrochanteric rotation osteotomy sec Sugioka. The postoperative following of the patients was 6 months to 5 years. Results: In years 1997 Ð 2002 we performed 7500 operations, 62 of them were pelvic osteotomies combined with intertrochanteric osteotomy and debridement of the hip. The age of patients varied between 18 and 68 years, 37 of them were women and 25 men. Oldest men was 58, youngest 24 years, oldest woman was 68 years and the youngest one was 18 years old. In 22 patients (35,5%) the results were very good, in 29 patients (46,8%) patients the results were good, in 3 patients (4,8%) the results were not sufþcient. In 8 patients (12,9%) the state remained unchanged. Conclusions: The results of above mentioned operations performed at The 2nd Department of Orthopaedic at the Faculty of Medicine of Comenius University, Bratislava, show good results. We continue indicating the combined one-stage osteotomy of the pelvis with intertrochanteric osteotomy and debridement of the hip

Purpose: We conducted a prospective study among elderly women with a first hip fracture to document survival and functional outcome, and to determine whether outcomes differ by fracture type. Methods: The design was a one-year prospective cohort study in the context of standard day-to-day clinical practice. The main outcome measures were survival and functional outcome, both at hospital discharge and one year later. Functional outcome was assessed using the Rapid Disability Rating Scale version-2. Results: Of the 170 women originally enrolled, 86 (51%) had an intertrochanteric and 84 (49%) a femoral neck fracture. There were no significant differences between the two groups with respect to median age (80 and 78 years, respectively), type and number of comorbidities, and prefracture residence at the time of injury. At hospital discharge, intertrochanteric hip-fracture patients had a higher mortality (relative risk [RR] 9.8; 95% confidence interval [CI]: 1.3 to 74.6; p=0.006) and were functionally more impaired (0.4 units difference in ability to walk independently; p=0.005). One year later, mortality was still significantly higher after intertrochanteric fracture (RR 2.5; 95% CI: 1.3 to 5.1; p=0.008), but functional outcome among surviving patients was similar in both groups. During the one-year period after hospital discharge, a significant functional recovery was observed regardless of fracture type (improvement by 3.9 units [p=0.003] and by 2.6 units [p=0.015] in patients with intertrochanteric and femoral neck fractures, respectively). In both groups, this recovery was reflected in a significant improvement in walking ability (p< 0.001 and p=0.006, respectively) and mobility (p=0.004 and p< 0.001, respectively). Conclusions: We conclude that intertrochanteric fractures are associated with increased mortality compared to femoral neck fractures. Functional outcome differs according to fracture type at hospital discharge, but these differences do not persist over time. Our data provide evidence that these findings cannot be explained by differences in age or comorbidity. Differences in survival suggest that the two main types of hip fractures should be analyzed separately in clinical and epidemiological studies

Aim

The most frequent mechanical failure in the osteosynthesis of intertrochanteric fractures is the cut-out. Fracture pattern, reduction quality, tip-apex distance or the position of the cervico-cephalic screw are some of the factors that have been associated with higher cut-out rates. To date, it has not been established whether underlying bacterial colonization or concomitant infection may be the cause of osteosynthesis failure in proximal femur fractures (PFF). The primary objective of this study is to assess the incidence of infection in patients with cut-out after PFF osteosynthesis.
