Lopez-Hualda A, García-Cabrera EM, Lobato-Perez M, Martinez-Martin J, Rossettini G, Leigheb M, Villafañe JH. Mechanical Complications of Proximal Femur Fractures Treated with Intramedullary Nailing: A Retrospective Study. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:718. [PMID: 38792901 PMCID: PMC11123330 DOI: 10.3390/medicina60050718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Revised: 04/22/2024] [Accepted: 04/24/2024] [Indexed: 05/26/2024]
Abstract
Background and Objectives: This retrospective cohort study analyzes mechanical complications in hip fracture surgery using the Trochanteric Fixation Nail-Advanced (TFNA) implant. It investigates the correlation of these complications with demographic, intraoperative, and radiological factors, aiming to identify associated risk factors and suggest improvements in clinical surveillance and treatment strategies. Materials and Methods: We enrolled 253 patients diagnosed with pertrochanteric hip fractures treated between 2017 and 2021, with 126 meeting the criteria for a minimum 6-month follow-up. Data on demographics, American Anesthesia Association Classification (ASA), comorbidities, AO/OTA [AO (Arbeitsgemeinschaft für Osteosynthesefragen)/OTA (Orthopedic Trauma Association)] fracture classification, procedural details, and time to failure were collected. Radiographs were evaluated for reduction quality, the tip-apex distance (TAD), progressive varus deviation, and identification of mechanical complications. Statistical analysis was performed using SPSS software. Results: The predominant AO/OTA fracture classification was 31A2 in 67 cases (52.7%). Reduction quality was deemed good or acceptable in 123 cases (97.6%). The mean time to failure was 4.5 months (range: 2.2-6). The average TAD was 18 mm (range: 1.2-36), with a mean progressive varus deviation of 2.44° (range: 1.30-4.14). A good or acceptable reduction quality was observed in 97.6% of cases. Mechanical complications occurred in 21.4% of patients, with significant associations found with the lateral cortex fracture, use of a TFNA implant with a 130° angle, open reduction, and absence of prior osteoporosis treatment. Conclusions: The study provides insights into mechanical complications in proximal femur fractures treated with the TFNA nail, emphasizing the need for enhanced clinical and radiographic surveillance, especially in patients without osteoporosis treatment. Our findings support the necessity for further clinical studies comparing these outcomes with other implant designs and underscore the importance of personalized treatment strategies to reduce complication rates.

Proximal femoral nail anti-rotation vs dynamic hip screws decrease the incidence of surgical site infections in patients with intertrochanteric fractures: A meta-analysis. Int Wound J 2023; 20:3212-3220. [PMID: 37095692 PMCID: PMC10502260 DOI: 10.1111/iwj.14200] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 04/06/2023] [Accepted: 04/07/2023] [Indexed: 04/26/2023] Open
Abstract
In this study, a meta-analysis was conducted to comprehensively analyse the effectiveness of using proximal femoral nail anti-rotation (PFNA) and dynamic hip screws (DHS) to treat intertrochanteric fractures on postoperative surgical site infections (SSI). PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang databases were searched from their inception until December 2022 to identify studies that compared PFNA and DHS in the treatment of intertrochanteric fractures. Two investigators independently screened the retrieved studies to assess their quality and verify their eligibility for inclusion. Meta-analyses were performed with RevMan 5.4 software. Thirty studies, including 3158 patients, met the inclusion criteria. These studies included 1574 patients treated with PFNA, and 1584 were treated with DHS. The findings of the meta-analysis revealed a significant reduction in the incidence of SSI in patients treated with PFNA compared with those treated with DHS (2.64% vs 6.76%, odds ratio [OR]: 0.40, 95% confidence intervals [CIs]: 0.28-0.57, P < .001), superficial SSI (2.58% vs 5.01%, OR: 0.53, 95% CIs: 0.33-0.85, P = .008) and deep SSI (1.26% vs 3.43%, OR: 0.41, 95% CIs: 0.19-0.92, P = .03). PFNA was more effective than DHS in reducing the incidence of SSI. Even so, significant variations in sample sizes among the included studies meant that the methodology for some studies had qualitative deficiencies. Therefore, additional studies with large sample sizes are needed to validate these results.

Eur J Trauma Emerg Surg 2019; 46:955-962. [PMID: 31520157 DOI: 10.1007/s00068-019-01200-7] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2019] [Accepted: 07/28/2019] [Indexed: 11/29/2022]
Abstract
INTRODUCTION Third-generation nails for the management of unstable trochanteric fractures were evaluated with regard to outcomes. PATIENTS AND METHODS A prospective observational study comparing the Gamma 3 nail and the Proximal Femoral Nail Antirotation (PFNA) in 106 unstable trochanteric fractures confirms the recently reported low intra- and postoperative complication rates from retrospective cohort studies. RESULTS Studies of same generations of both intramedullary nail systems did not reveal significant differences in intra- or postoperative complications. Intraoperative dislocation during nail insertion occurred 7 times for the Gamma nail and 9 times for the PFNA. The standard PFNA had to be exchanged intraoperatively for a shorter one on two occasions. Superficial wound healing disorders and hematoma requiring revision were observed in four patients in the Gamma 3 nail group and in three patients in the PFNA group. No deep infections were documented. Mechanical complications required revision in four patients (7.5%) after Gamma nailing and in two patients (3.8%) after PFNA. Postoperative rotation of the head-neck fragment was observed for the Gamma nail in three patients, not in the PFNA group. This was not statistically significant (p = 0.08). There were neither incidences of cut out without renewed trauma nor intraoperative fracture or postoperative femoral fracture. Nonunion affected 1 of 18 patients in late follow-up (p = 0.3) in the Gamma 3 nail group. DISCUSSION The Gamma 3 nail and the PFNA yielded comparable clinical results and significantly improved outcomes for unstable trochanteric fractures compared to older nail generations.

Abstract
INTRODUCTION To present the effect of the cerclage fixation, which was performed for the purpose of preserving the alignment obtained by open reduction, on the long-term clinical and radiological results of subtrochanteric fractures. MATERIALS AND METHODS The inclusion criterias were at least 2 years of follow-up, no severe cognitive impairment, and to be able to walk independently prior to fracture. Patients with transverse or short oblique subtrochanteric hip fractures (AO/OTA class 32-A3.1), patients underwent previous femoral or hip operation for the same side and those with segmental fractures, bilateral fractures and pathological fractures were not included in the study. The clinical and radiological results of the patients were evaluated. The clinical evaluations were performed with Palmer and Parker Mobility Score (PPM), Lower Extremity Functional Score (LEFS), visual analogue score (VAS) and return to pre-injury activity status. The elapsed time between the trauma and the surgery date, the duration of surgery the estimated amount of bleeding, and the length of hospital stay of patients were assessed. RESULTS Thirty-two of the 52 patients were female and 20 were male. The mean age of females was 77.80 ± 9.75 years and the mean age of the males was 79.18 ± 6.50 years. The mean follow-up period of the patients was 62.25 ± 34.68 months. The mean time until the patients' surgery was 6.18 ± 3.32 days. The mean duration of surgery was 52.6 ± 13.8 min. The mean amount of bleeding was 176 ± 90 ml. The mean length of patients' hospital stay was 6.2 ± 3.2 days. The postoperative mean duration of union was found to be 3.8 ± 1.6 months. The mean value of varus/valgus angulation in coronal plane measurements was 0.52°. No complication was observed in any patient during the cerclage application. The mean number of wire was 1.3. LEFS difference was statistically significant. PPM decline was not statistically significant. CONCLUSION Open reduction and the use of cerclage did not produce a negative effect in terms of fracture union. The generation of medial support by anatomical reduction of the fracture prevents the implant failure and provide a basis for union.

Abstract
Objective The primary aim of this study was to survey current practices and preferences behind internal fixation of trochanteric femoral fractures among Brazilian orthopedic surgeons. The secondary aim was to identify the main reason for these preferences. Methods A survey containing 20 images of trochanteric fractures of the femur was presented to a group of 62 orthopedists, all members of the Brazilian Society of Orthopedics and Traumatology (SBOT). The first part of the questionnaire was created to identify the surgeons' degree of professional experience, type of practice, and areas of greatest interest and performance within the specialty. The second part of the questionnaire contained options for fixating different trochanteric fracture patterns in the femur for participants to choose, along with the main reason for their decision. Statistical analysis was descriptive and profiled the surgeons' major area of interest, treatment option, and the main reason for their therapeutic decision. Results Of the 62 orthopedists who participated in the study, 10 (16.0%) stated that their area of greatest interest was orthopedic trauma and 52 (83.9%) reported greater interest in another area of the specialty; these two groups were classified as the Trauma Group and Orthopedics Group, respectively. To treat AO 31A1 type fractures, the trauma group selected the sliding hip screw (SHS) in 66.7% of cases, while the orthopedics group chose the SHS in 65.8% of cases. For 31A2 type fractures, the trauma group chose the intramedullary (IM) nail in 64.0% of the cases, while the orthopedics group chose the IM nail in 76.7% of the cases. For 31A3 type fractures, the trauma group opted for the IM nail in 70.0% of the cases, while the orthopedics group selected the IM nail in 88.0% of the cases. The two most important factors in implant selection for the three types of fracture were fracture pattern and implant availability. Conclusion The sliding hip screw is preferred by most Brazilian orthopedic surgeons for fixation of 31A1 type trochanteric femoral fractures. For 31A2 and 31A3 type fractures, the IM nail is preferred.

Abstract
Cephalomedullary nail (CMN) failure is a rare entity following hip fracture treatment. However, it poses significant challenges for revision surgery, both mechanically and biologically. Nail failure rates have been reported at < 2%; however, no published studies have reported revision surgery procedures and their respective outcomes. We present a regional experience, with outcomes, of the revision options. We identified 20 fatigued CMNs that underwent four different revision procedures. Mean age was 73 ± 15.24 years, with a 3:1 female preponderance, and a median ASA grade of 3. Post-operative CMN radiographs demonstrated a significant number of fractures were fixed in varus, with reductions in neck-shaft angles post-operatively. A "poor" quality of reduction resulted in significantly earlier nail failure, compared to "adequate" and "good" (p = 0.027). Tip-Apex Distance (TAD) mean was 23.2 ± 8.3 mm, and an adequate TAD with three-point fixation was seen in only 35% of cases. Mean time to failure was 401.0 ± 237.2 days, with mean age at failure of 74.0 ± 14.8 years. Options after failure included revision CMN nail, proximal femoral locking plate (PFLP), long-stem or restoration arthroplasty, or femoral endoprosthesis. Barthel Functional Index scores showed no significant difference at 3 and 12 months post-operatively, nor any difference between treatment groups. Mean 12-month mortality was 30%, akin to a primary hip fracture mortality risk according to NICE guidelines. Mortality rates were lowest in revision nails. Subsequent revision rates were higher in the PFLP group. There is no reported evidence on the best surgical technique for managing the failed CMN, with no clear functional benefit in the options above. Good surgical technique at the time of primary CMN surgery is critical in minimising fatigue failure. After revision, overall mortality rates were equivalent to reported primary hip fracture mortality rates. Further multicentre evaluations are required to assess which technique convey the best functional outcomes without compromising 12-month mortality rates.

Reverse polyaxial less invasive stabilization systems for treatment of femoral intertrochanteric fractures of the distal femur. Arch Orthop Trauma Surg 2016; 136:1531-1537.

Abstract
INTRODUCTION The reverse less invasive stabilization system (LISS) for the distal femur remains generally regarded as a safe and satisfactory option for the treatment of unstable proximal femoral fractures. The polyaxial LISS provides a reverse plating technique that leverages the advantages of proximal screws by allowing the adjustable locking screw to be better positioned and providing more reliable fixation on the proximal femur compared with the standard axial LISS. To assess this fixation method, a detailed evaluation of institutional outcomes of femoral intertrochanteric fractures treated with reverse polyaxial LISS was performed. MATERIALS AND METHODS A total of 29 patients presenting with femoral intertrochanteric fractures were treated with the reverse polyaxial LISS system between January 2010 and March 2011. Patients were classified into stable and unstable fracture groups according to the Orthopaedic Trauma Association's (OTA) classification. Clinical data, including operative time, blood loss, radiological records and complications, Harris Hip scores and Parker scores, were collected and analyzed. RESULTS There were no significant between-group differences in age, sex, or American Society of Anesthesiologists score. Operative time and blood loss were significantly higher in the unstable fracture group compared with the stable fracture group. Four cases of fixation failure, consisting of one case of A2.3, one case of A3.2 and two cases of A3.3, occurred 4-7 m postoperatively. CONCLUSIONS Treatment of femoral intertrochanteric fractures with unstable pattern using polyaxial reverse LISS results in high failure rates; therefore, it should not be recommended as a routine alternative method for the treatment of femoral intertrochanteric fractures with unstable pattern.

Abstract
The aim of this study was to assess any possible correlation between body weight and fracture union following displaced intracapsular fractures of the neck of femur treated by a closed reduction and internal fixation. A total of 198 patients with such injuries treated by closed reduction and internal fixation, were recruited retrospectively. Patients were followed up until fracture endpoint (union or non-union) with a minimum follow up of 100 days. The mean body weight for the 118 patients without fracture healing complications was 64.6 kg versus 61.8 kg for the 80 patients with complications, a difference that was not statistically significant (p=0.17). Analysis of data related to sex and age also found no relationship between weight and fracture healing complications. Our results indicate there is no relationship between body weight and fracture healing complications following displaced intracapsular fractures treated by internal fixation.

Abstract
OBJECTIVE The goal of the study was to compare functional results in different treament options in cutting-out, and analize factors associated to failure. MATERIAL AND METHODS Retrospective cohort study in 56 patients diagnosed with cutting-out between 2000-2010. Groups were based on rescue treatment: arthroplasty versus alternative treatment. Demographics, fracture characteristics, osteosynthesis, tip to apex distance (TAD), follow-up, complications, and final functional capacity were analyzed. RESULTS Rescue treatment: 36 (64.28%) hip replacement (arthroplasty group), and 20 (35.72%) alternative treatment preserving femoral head (alternative group). Groups comparable on demographic parameters, fracture pattern and osteosynthesis characteristics. Radiography analysis: low inter-observer variability (k=0.83, 95% CI 0.78-0.88), mean TAD 28.66mm (arthroplasty group 32.9mm, 21.5mm control group; p=0.01), insufficient fracture reduction 39.3% (p=0.001). Cutting-out diagnosis median 60 days (arthroplasty group 90 days, 18 days alternative group; p=0.001). Follow up at least 12 months from rescue treatment. Similar complications rate in both groups (p=0.16). Re-operation rate 3.57% (11.7% arthroplasty group, alternative group 0%; p=0.01). Better final functional capacity in arthroplasty group (p=0.004). DISCUSSION Hip arthroplasty offers better results, being considered the gold standard in geriatric patients, although re-operation rate is higher. We recommend new nailing before arthroplasty in early failure (4 weeks) in patients with femoral head integrity. An insufficient fracture reduction is the main short term factor predicting failure; and TAD higher than 20mm is a middle-long term one.

Abstract
Osteoporotic fractures are associated with excess mortality and decreased functional capacity and quality of life. Age-standardized incidence rates of fragility fractures, particularly of the hip and forearm, have been noted to be decreasing in the last decade across many countries with the notable exception of Asia. The causes for the observed changes in fracture risk have not been fully identified but are likely the result of multiple factors, including birth cohort and period effects, increasing obesity, and greater use of anti-osteoporosis medications. Changing rates of fragility fractures would be expected to have an important impact on the burden of osteoporosis.

Abstract
Intramedullary fixation is the mainstay of treatment for femur fractures in the adult trauma population. With subtrochanteric fractures, accurate reduction and stable fixation become technically challenging. Adjuvant blocking screws in the proximal fragment can effectively be used to prevent varus and apex anterior malalignment when intramedullary nails are used in these fractures. Blocking screws decrease the canal volume, thereby allowing the intramedullary device to control the proximal segment. This aids in improving alignment between the proximal and distal fragments during reduction. We review the cases of six patients with proximal femur fractures who were treated with intramedullary nailing in conjunction with the placement of blocking screws.

Abstract
PURPOSE The aim of this study was to compare two intramedullary devices used in the treatment of intertrochanteric fractures. METHOD During the period 2006-2007 46 TGN and 51 PFNA were used for the treatment of intertrochanteric fractures in our hospital. Clinical and radiological follow-up were available. Surgical time, blood loss and complications have been considered. RESULTS The mean operative time for the TGN group was significantly higher than in the PFNA group (62 min and 45 min, respectively) with a p = 0.04. The mean blood loss was significantly higher in the TGN group (285 ml; SD 145) in relation to the PFNA group (226 ml; SD 136) with p = 0.03. Also, rate of complications was higher in the TGN group (p = 0.01). Clinical outcomes were good for both groups. Intra-operative and post-operative complications in the TGN group were associated with a longer operative time and a higher blood loss, probably due to the reaming needed in TGN that can increase blood loss and risk of comminution or fracture propagation. Moreover, all but one of the procedure-related complications were observed in very elderly patients. CONCLUSIONS Based on our results in the intertrochanteric fracture, use of PFNA should be recommended in cases of elderly and osteoporotic patients, while TGN should be used in more severely displaced fractures in patients with a slightly better bone mineral density.

Abstract
BACKGROUND Bipolar hip hemiarthroplasty is used in the management of fractures of the proximal femur. The dual articulation is cited as advantageous in comparison to unipolar prostheses as it decreases acetabular erosion, has a lower dislocation rates and is easier to convert to a total hip arthroplasty (THA) should the need arise. However, these claims are debatable. Our study examines the rate of conversion of the bipolar hemiarthroplasty to THA and the justification for using it on the basis of future conversion to THA. METHODS All cases of bipolar hemiarthroplasty performed in our unit for hip fractures over a 9-year period (1999-2007) were reviewed. Medical notes and radiographs of all patients were reviewed, and all surviving patients that were contactable received a telephone follow-up. RESULTS Of all 164 patients reviewed with a minimum of 1 year from date of surgery, 4 patients had undergone a conversion of their bipolar prosthesis to THA. Three conversions were performed for infection, dislocation, and fracture. Only one (0.6%) conversion was performed for groin pain. CONCLUSIONS Our study show that bipolar hemiarthroplasties for hip fractures have a low conversion rate to THAs and this is comparable to the published conversion rate of unipolar hemiarthroplasties.

Subtrochanteric hip fractures treated with cerclage cables and long cephalomedullary nails: a review of 17 consecutive cases over 2 years. Injury 2011; 42:1317-21.

Abstract
BACKGROUND The conflict between the anatomist and biologist surgeons is exemplified by the debate about subtrochanteric hip fractures. Closed intramedullary nailing is biologically friendly but may result in prolonged procedures and malunion. By contrast, accurate anatomical open reduction may disturb the biological composition of the fracture environment. METHODS There were 17 patients at our institution over a 2-year period whose long oblique subtrochanteric fractures would not reduce perfectly in an anatomical fashion using closed methods. All these patients had their fractures treated identically using a new policy at our unit. This strategy involved reduction of the fracture through an open approach, and then employing cerclage cables to stabilise the fracture in an anatomical position before finally inserting a cephalomedullary nail. These patients were retrospectively reviewed at an average of 18 months postoperatively, to assess their progressive functional and radiological outcome up to that point. RESULTS One patient had nonunion and required a secondary procedure. One patient died 8 days postoperatively from a medical complication. The remaining 15 healed within 6 months and all returned to independent living. CONCLUSIONS The results demonstrate that judicious use of cerclage cables to augment fixation of subtrochanteric femur fractures does not have a deleterious effect on healing. One should endeavour, however, to minimise the number of cables used. The basic science literature underpinning our approach to these unstable fractures is also discussed.

Abstract
Treatment of medial femoral fractures in elderly patients with cemented hip hemiarthroplasty (HEP) is a widely established procedure. The main problems with this procedure are complications associated with soft tissue damage and prolonged immobilization. The aim of this study was to compare the clinical and radiological results after HEP implantation using either an anterior minimally invasive (MIS) approach or a regular transgluteal (TG) approach. In this retrospective study the results of 55 consecutive MIS and 54 consecutive TG approaches for implanted HEP after medial femoral fracture were compared. The time of successful mobilization, duration of the i.v. analgesia as well as the occurrence of any perioperative complications were recorded. The femoral offset, leg length and the femoral alignment were analyzed radiologically. The MIS group could be mobilized earlier (MIS 2. pod vs. TG 4. pod, p <0.01) but the need for i.v. applied analgesia was prolonged (MIS 4.4 pod vs. TG 3.5 pod, p=0.04). In the MIS group the number of perioperative complications was less than in the TG group (MIS 7% vs. TG 17%, p <0.05). The early functional advantages of MIS after HEP implantation for medial femoral fractures are evident also within an elderly group of patients.

Abstract
INTRODUCTION Prosthetic joint infection (PJI) after femoral neck fracture is associated with a higher mortality, morbidity and economic costs. Although is well known that the presence of a post surgical haematoma is associated with infection, in our knowledge there are no articles evaluating the contamination of the femoral neck fracture haematoma and the possible relationship with early postoperative PJI. The aim of our study was to evaluate the prevalence of positive cultures from haematoma in patients with femoral neck fracture and the relationship with early PJI. METHODS A prospective observational study was performed. All patients who underwent hiphemiarthroplasty for a femoral neck fracture from April'08 to February'09 were included. Three samples were taken just after the arthrotomy, a tissue sample, a swab of haematoma and blood of haematoma inoculated into blood culture flasks. Patients received the standard prophylaxis. RESULTS A total of 109 patients were treated during this period in our center, 16 were excluded for mistakes during taking samples or for receiving extra antibiotic treatment after or before the surgery of the fracture. In 29 patients (31.2%) one or more intraoperative cultures were positive. Four patients developed an early PJI caused by Gram-negative bacilli (GNB) in all cases. The early PJI rate in the group of patients with negative intraopertive cultures was 3.1% while in the group with one or more positive cultures was 6.9% (p = 0.3). In 3 cases the haematoma was contaminated with a GNB. The PJI rate inpatients with intraoperative cultures positive for a GNB was 66.6% (2/3) while in the group of patients without a GNB the infection rate was 2.2% (2/89, p = 0.004, Fisher exact-test). Furthermore in these two patients the microorganism that caused the PJI was the same that had been isolated from the haematoma. CONCLUSION The haematoma in femoral neck fractures was contaminated in 31.2% of cases before surgery. The contamination of the haematoma with a GNB was associated with a higher risk of early postoperative PJI.

Abstract
BACKGROUND Femoral intramedullary nailing is currently one of the most frequent surgical treatments for extracapsular hip-fracture fixation. Cutting-out of the lag screw is the main complication of this technique, but only few studies have approached the cutting-out focussed on femoral nailing. The aim of this study was to confirm in patients treated with intramedullary nailing not only with regard to previous reports about the association of cutting-out with technical factors, but also with regard to clinical factors not previously studied. METHODS Case-control study of all patients sustaining a cut-out of the femoral nail was carried out and a control sample was randomly selected among all extracapsular hip-fracture patients during the study period (2005-2008). All clinical and technical variables were collected from medical records. Orthopaedic Trauma Association (AO/OTA) fracture classification, Singh Osteoporosis Index of the contralateral hip and the American Society of Anaesthesiology (ASA) criteria for preoperative clinical status were used. Statistical assessment included bivariant analysis and multivariant logistic regression analysis. RESULTS A total of 916 hip-fracture cases were treated in the study period: 33 of them (3.6%) were identified as suffering cutting-out, and 315 controls fulfilling inclusion criteria were also recruited. No statistical differences were found in age, sex or other socio-demographic variables between the two groups. Bivariant analysis showed significant differences between groups in technical variables (tip-apex distance, suboptimal placement of lag screw, fracture diastasis, inadequate fixation quality and distal static locking) and in clinical variables (osteoporosis severity, right hip affected, better previous ability for walking and better preoperative ASA status). Multivariant logistic regression analysis showed significant association only for tip-apex distance and inadequate fixation quality. Differences in distal static locking were close to statistical significance. CONCLUSIONS The strongest predictor of cutting-out in femoral nailing is tip-apex distance. This study suggests that distal static locking and other clinical conditions play an important role in this fixation failure.

Abstract
Geriatric fractures are an increasing medical problem worldwide. This article wants to give an overview on the literature concerning the outcome to be expected in geriatric fracture patients and what can be done to improve it. In literature, excess mortality rates vary from 12% to 35% in the first year after a hip fracture, and also, other geriatric fractures seem to reduce the patient's remaining lifetime. Geriatric fractures and, in particular, hip fractures constitute a major source of disability and diminished quality of life in the elderly. Age, gender, comorbid conditions, prefracture functional abilities, and fracture type have an impact on the outcome regarding ambulation, activities of daily living, and quality of life. Comprehensive orthogeriatric comanagement might improve the outcome of geriatric fracture patients. For the future, well designed, large prospective randomized controlled trials with clear outcome variables are needed to finally prove the effectiveness of existing concepts.

Abstract
INTRODUCTION Internal fixation is the preferred treatment of Garden I femoral neck fractures in the elderly. High re-operation rates have however been reported, and the results of arthroplasty performed following internal fixation failure are not as good as those of primary arthroplasty. This is why we are advocating functional treatment. Our hypothesis is that this treatment leads to fewer decubitus complications than strict orthopaedic treatment and no more mechanical complications than internal fixation in a selected population sample. Therefore, the objective of our prospective work was: (1) to assess the results of functional treatment of Garden I femoral neck fractures in elderly subjects, and (2) to investigate predictive factors of secondary displacement. PATIENTS AND METHODS All patients over age 65 years, admitted for a Garden I femoral neck fracture between January 2006 and May 2008, were included in this prospective study representing 56 cases (57 fractures) with an average age of 82 years. Functional treatment was performed, including early weight-bearing mobilisation, followed by radiographic evaluation at days 2, 7, 21 and 45, then at 3, 6 and 12 months. In the absence of displacement, discharge was planned at day 5 (Non-Displaced [ND] group). Otherwise, arthroplasty was performed (Displaced [D] group). Parker score and Harris Hip Score (HHS) were used for functional evaluation. RESULTS The observed displacement rate was 33.3% (19 patients) within an average period of 10 days. In the ND group, one case of osteonecrosis was observed and treated by arthroplasty. The average Parker score was 6.9 and the HHS 82 in the ND group, and 7 and 85, respectively, in the D group. None of the factors studied (age, gender, side, fracture type, inclination angle, degree of outward displacement, sagittal displacement, general status) was statistically predictive of final displacement. DISCUSSION The medical complication rate was only 7% in our series, which seems to be lower than that resulting from orthopaedic treatment. The observed secondary displacement rate seemed to be higher than the rate found in the literature on surgical treatment (5.4 to 20%), but the osteonecrosis rate appeared to be lower (11 to 25%). In addition, surgical treatment was the purveyor of specific complications in over 10% of cases. CONCLUSIONS The present prospective study with minimum 1-year follow-up shows that functional treatment results in fewer decubitus complications than orthopaedic treatment and a rate of revision surgery comparable to internal fixation since 70% of included patients could have been successfully treated without surgical intervention. However, the investigation of a larger cohort would be necessary to identify predictive factors for the treatment's failure. LEVEL OF EVIDENCE Level III prospective non-comparative cohort study.

Abstract
Fracture non-unions often complicate orthopaedic trauma. BMPs (bone morphogenetic proteins) are currently considered the most appealing osteoinductive agents. Applications of BMP-7 since January 2004 were prospectively recorded in a multicentre registry of aseptic femoral non-unions. The study included 30 patients who had undergone a median of 1 revision operation before BMP-7 application and who were followed up for a median 24 months. In 23/30 cases the application of BMP-7 was combined with revision of the fixation, and in 12 it was combined also with autograft. Non-union healing was verified in 26/30 cases in a median period of 6 months. No adverse events were associated with BMP-7 application. Our case series supports the safety and efficacy of BMP-7 in femoral non-unions. Multicentre networks and systematic, long-term follow-up of patients may improve understanding of this promising osteoinductive bone substitute.

Abstract
Although reamed intramedullary nailing has long been considered a safe procedure, pulmonary complications have been reported in some groups of patients. Concerns over fat embolisation, adult respiratory distress syndrome (ARDS), and sudden intraoperative death have prompted some authors to question whether the benefits of reaming are outweighed by its potential adverse effects to the patient. In response to these complications, recent evaluations have focused on alternative systems that reduce intramedullary pressure during reaming. The Reamer/Irrigator/Aspirator (RIA) system (Synthes, Inc., West Chester, PA) was developed as a simultaneous reaming and aspiration system to reduce the intramedullary pressure, heat generation, operating time, and systemic effects of reaming. It was designed with an aggressive one-pass reamer head which is connected to a hand-held reamer via a drive shaft, simultaneously irrigating and aspirating femoral canal contents during reaming, thus preventing thermal necrosis and fat embolisation. After its early use, investigators examined the "aspirate" captured by the RIA which appeared to be loaded with osteogenic substrates. This discovery revealed a second potential use for the RIA-a bone graft harvester. The different design characteristics and technicalities of the RIA system necessitate a deep and clear understanding of its technique, a meticulous preoperative planning and a strict adherence to its principles intraoperatively. We present our current approach to the use of the RIA system, including the preoperative planning, the details of the operative procedure, the pitfalls and the potential complications that could be encountered.

Abstract
In order to evaluate the impact of simultaneous intramedullary nailing in patients with bilateral femoral fractures on systemic complications a comprehensive review of the literature was performed. Four studies reporting the results of 197 patients following trauma were analysed. The mean Injury Severity Score was 20.6 (range, 9-75). According to the data available, reamed intramedullary nailing was performed in 96% of the cases. The incidence of fat embolism was 4.1%, ARDS 14.6% and pulmonary embolism 6.9%. The overall mortality was 6%. The mean hospital stay was 17.9 days (range, 4-108). Bilateral femoral fractures have a high risk of complications and mortality. Damage control surgery should be considered in these cases where the clinician anticipates the development of systemic complications.
