Aims: The aim of this study was to investigate the safety and efficacy of 3D-printed modular prostheses in patients who underwent joint-sparing limb salvage surgery (JSLSS) for malignant femoral diaphyseal bone tumours. Methods: We retrospectively reviewed 17 patients (13 males and four females) with femoral diaphyseal tumours who underwent JSLSS in our hospital. Results: In all, 17 patients with locally aggressive bone tumours (Enneking stage IIB) located in the femoral shaft underwent JSLSS and reconstruction with 3D-printed modular prostheses between January 2020 and June 2022. The median surgical time was 153 minutes (interquartile range (IQR) 117 to 248), and the median estimated blood loss was 200ml (IQR 125 to 400). Osteosarcoma was the most common pathological type (n = 12; 70.6%). The mean osteotomy length was 197.53 mm (SD 12.34), and the median follow-up was 25 months (IQR 19 to 38). Two patients experienced local recurrence and three developed distant metastases. Postoperative complications included wound infection in one patient and screw loosening in another, both of which were treated successfully with revision surgery. The median Musculoskeletal Tumor Society score at the final follow-up was 28 (IQR 27 to 28). Conclusion: The 3D-printed modular prosthesis is a reliable and feasible reconstruction option for patients with malignant femoral diaphyseal tumours. It helps to improve the limb salvage rate, restore limb function, and achieve better short-term effectiveness. Cite this article: Bone Jt Open 2024;5(4):317–323.

Aims: Despite limited clinical scientific backing, an additional trochanteric stabilizing plate (TSP) has been advocated when treating unstable trochanteric fractures with a sliding hip screw (SHS). We aimed to explore whether the TSP would result in less post operative fracture motion, compared to SHS alone. Methods: Overall, 31 patients with AO/OTA 31-A2 trochanteric fractures were randomized to either a SHS alone or a SHS with an additional TSP. To compare postoperative fracture motion, radiostereometric analysis (RSA) was performed before and after weightbearing, and then at four, eight, 12, 26, and 52 weeks. With the “after weightbearing” images as baseline, we calculated translations and rotations, including shortening and medialization of the femoral shaft. Results: Similar migration profiles were observed in all directions during the course of healing. At one year, eight patients in the SHS group and 12 patients in the TSP group were available for analysis, finding a clinically non-relevant, and statistically non-significant, difference in total translation of 1 mm (95% confidence interval -4.7 to 2.9) in favour of the TSP group. In line with the migration data, no significant differences in clinical outcomes were found. Conclusion: The TSP did not influence the course of healing or postoperative fracture motion compared to SHS alone. Based on our results, routine use of the TSP in AO/OTA 31-A2 trochanteric fractures cannot be recommended. The TSP has been shown, in biomechanical studies, to increase stability in sliding hip screw constructs in both unstable and intermediate stable trochanteric fractures, but the clinical evidence is limited. This study showed no advantage of the TSP in unstable (AO 31-A2) fractures in elderly patients when fracture movement was evaluated with radiostereometric analysis.

IntroductionOptimal paediatric femoral shaft fracture patterns or lengths amenable to titanium elastic nail stabilization have not been well defined. The purpose of this study is to identify radiographic parameters predictive of treatment failure with flexible intramedullary nails based upon fracture morphology.MethodsA retrospective review was performed of all femoral shaft fractures treated with flexible intramedullary nails over a five-year period. All patients with at least six weeks of postoperative radiographic imaging were included. Fracture characteristics included location, pattern, length, obliquity, angulation, translation and shortening. Postoperative radiographs were reviewed to determine shortening and angulation.ResultsThere were 58 patients with 60 femoral shaft fractures stabilized with titanium nails, with 46 healing within acceptable parameters and 14 considered malunions. Six of the 14 malunions developed complications requiring early unplanned intervention. No patients in the treatment success group had a complication. Between the treatment success and failure groups, fracture pattern, location, length, obliquity, angulation, translation or shortening were not statistically different. Mean nail canal fill was significantly lower in the failure group (0.72 versus 0.81; p = 0.0146), with a receiver operating characteristic curve identifying canal fill 76% as the optimal threshold.ConclusionThis is the first study to measure the length and obliquity of paediatric femoral shaft fractures and to determine their relationship to radiographic alignment after healing. None of the preoperative fracture characteristics were predictive of malalignment or shortening. We recommend the use of larger nail sizes in the treatment of paediatric femoral shaft fractures, especially if there is concern for residual instability.Level of evidenceIV.

Abstract Background Closed reamed locked intramedullary nailing has been the treatment of choice for most of femoral shaft fractures. A high union rate with a low complication rate is generally predictable. For an aseptic femoral shaft nonunion with a prior inserted intramedullary nail, exchange nailing is one of favored surgical techniques for treatment. However, a greatly varied success rate of 72–100% has been reported. To improve the success rate of exchange femur nailing, a modified bone grafting technique was developed. The purpose of this retrospective study intended to evaluate outcomes of such a revised technique. Methods From July 2011 to March 2019, 48 consecutive adult patients (average, 38 years; range, 19–67 years) with aseptic femoral shaft nonunions after intramedullary nailing treatment were studied. All femoral shaft fractures were initially caused by traffic accidents, which were treated by a closed or open intramedullary nailing technique at various hospitals. The current revision treatment was performed after an average of 2.2 years (range 1.1–6.2 years) from initial injuries. In the surgery, the prior nail was removed and the marrow cavity was reamed widely (at least 2 mm as possible). Sufficient cancellous bone grafts harvested on the trochanteric marrow wall from the inside were placed in the marrow cavity of the junction of nonunion fragments. A new 1-mm smaller size locked intramedullary nail was inserted. Whether the dynamic or static mode of nails were used mainly depended on the nonunion level. Postoperatively, protected weight bearing with crutches was allowed for all patients. Results Forty-one patients were followed for an average of 2.8 years (85.4%; range, 1.9–4.5 years) and all fractures healed. The union rate was 100% (41/41, p

PurposeTo examine clinical outcomes of a specialized modular prosthesis used to fill a bone deficiency following removal of femoral shaft metastases.MethodsEighteen patients with femoral shaft metastases who underwent en bloc resection and implantation of a personalized modular prosthesis between December 2014 and December 2019 were retrospectively analyzed. Pain, limb function, and quality of life were evaluated using the visual analog scale (VAS), Musculoskeletal Tumor Society (MSTS) scale, International Society of Limb Salvage (ISOLS) scoring system, Karnofsky Performance Status (KPS) scale, and Nottingham Health Profile (NHP) scale. The Kaplan–Meier technique was used to analyze patient survival.ResultsThe operation duration was 90–150 min (mean, 115 min), and the osteotomy length was 9–16 cm (mean, 11.72 cm). The patients were followed for 12–62 months (mean, 25.28 months). The VAS and NHP ratings were lower at 3, 6, and 12 months after surgery than before surgery, while the MSTS, ISOLS, and KPS scores were higher after surgery than they had been before. These differences were statistically significant (P

Abstract Background Postoperative adverse events after intramedullary nailing have been reported in patients with metastatic pathological and non-pathological femoral fractures. Other consequences to be considered are readmission and reoperation. Few studies have compared the risks of postoperative adverse events, reoperation, and readmission after intramedullary nailing of pathological and non-pathological femur fractures. This study was designed to test the hypothesis that patients with pathological femoral fractures had more adverse events, readmission, and reoperation following surgical fixation than non-pathological femoral fractures. Methods This was a retrospective observational cohort study, conducted at an academic medical center in Thailand. The data from patients with femoral shaft fractures undergoing long intramedullary nailing, from June 1, 2006, to June 30, 2020, were included. Patients who had a pathological fracture from a primary bone tumor, metabolic bone disease, or inadequate/missing information were excluded. Patients with pathological fractures from metastatic bone disease were assigned to be the pathological group whereas those with traumatic fractures were assigned to be the non-pathological group. The primary outcome was the risk of inpatient adverse events as compared between the two groups. The secondary outcome was the risk of consequences after discharge as compared between the two groups. Outcomes were analyzed by using multivariate logistic regression analysis. Results The total number of patients was 48 in the pathological fracture group and 185 in the non-pathological group. There were significantly higher rates of surgical and medical adverse events in patients with pathological fractures compared to patients with non-pathological fractures. After adjusting for potential confounding factors in multivariate regression analysis, patients with pathological fractures had higher odds of both adverse surgical (adjusted OR 2.43, 95 % CI 1.15–5.13) and medical adverse events (adjusted OR 2.81, 95 % CI 1.13–7.03). Conclusions Patients with metastatic pathological femoral shaft fractures undergoing intramedullary nailing were more likely to experience postoperative adverse events than patients with non-pathological fractures.

The union rate was 100% (41/41, p < 0.001) with a union time of an average of 3.4 months (range, 2.5–5.0 months). There were no complications of deep infection, nonunions, malunions, implant failures or an avulsed trochanter tip fracture. The satisfactory knee function improved from 73.2% (30/41) preoperatively to 92.7% (38/41) at the latest follow-up (p = 0.019). Conclusions: The described modified bone grafting technique may effectively improve a union rate of exchange femur nailing while the surgical procedure is not complicated. It may therefore be used concomitantly in all aseptic femoral shaft nonunions when exchange nailing is performed. [ABSTRACT FROM AUTHOR]

Background and purpose: One of the most important complications of bone fractures is nonunion. This research aimed at comparing the effect of exchange nailing and plate augmentation on complications after surgery and the time to achieve desired outcomes. Materials and methods: This descriptive-analytical study was conducted in 12 femoral shaft nonunion cases treated operatively in 2011-2018 (eight patients were managed with plate augmentation and four patients were treated with exchange nailing). Demographic characteristics of the patients, type of fracture and type of surgery were recorded. A year after the surgery, anteroposterior and lateral view profiles were prepared from all patients and the extent of bone fusion was evaluated by orthopedic surgen. Results: Four patients (33.33%) underwent intraosseous nail replacement surgery and eight (66.67%) underwent plate augmentation surgery. Two patients (16.67%) developed infections and five (41.67%) had a short limb complication. The average limb shortness in these patients was 1.10±0.22 cm. The average duration of union after discharge was lower in patients with plate augmentation than those with replacement of the intramedullary nail. Conclusion: In current study, faster uninon achieved, so, augmentation plating could be a good choice in patients with femoral shaft nonunion.

Abstract Background Bisphosphonate (BP) therapy has been associated with atypical femur fracture (AFF). However, the threshold of treatment duration leading to increased AFF risk is unclear. In a retrospective cohort of older women initiating BP, we compared the AFF risk associated with treatment for at least three years to the risk associated with treatment less than three years. Methods We used observational data from a large population of female members of an integrated healthcare system who initiated oral BP during 2002–2014. Women were retrospectively followed for incident AFF confirmed by radiologic adjudication. Demographic data, pharmacologic exposures, comorbidity, bone density, and fracture history were ascertained from electronic health records. Inverse probability weighting was used to estimate risk differences comparing the cumulative incidence (risk) of AFF if women discontinued BP within three years to the cumulative incidence of AFF if women continued BP for three or more years, adjusting for potential time-dependent confounding by the aforementioned factors. Results Among 87,820 women age 45–84 years who initiated BP (mean age 68.6, median T-score − 2.6, 14% with prior major osteoporotic fracture), 16,180 continued BP for three or more years. Forty-six confirmed AFFs occurred during follow-up in the two groups. AFF-free survival was greater for BP treatment

Background: Postoperative adverse events after intramedullary nailing have been reported in patients with metastatic pathological and non-pathological femoral fractures. Other consequences to be considered are readmission and reoperation. Few studies have compared the risks of postoperative adverse events, reoperation, and readmission after intramedullary nailing of pathological and non-pathological femur fractures. This study was designed to test the hypothesis that patients with pathological femoral fractures had more adverse events, readmission, and reoperation following surgical fixation than non-pathological femoral fractures.

Any fracture of the femoral shaft presents a challenge to the orthopedic surgeon. Femoral fractures most often occur within polytrauma, by forces of high intensity as is the case with traffic accidents. There are two methods to treat with internal fracture fixation, intra and extra medullary fixation. Both treatments have their advantages and disadvantages and it is necessary to make a good preoperative plan. We present the case of a 23-year-old man who suffered a femoral shaft fracture as a driver in a car accident. He was initially surgically treated with orthopedic repositioning and internal, extramedullary fixation. After 18 months, bending of the osteosynthetic material and dislocation of the fragments with varus and recurvatum were verified. Oligotrophic pseudoarthrosis was also present. Reintervention and fixation with interlocking nail was performed. The weight bearing is allowed after two weeks. After 3 months, patient has full range of motion and there is no palpatory painful sensitivity. Intramedullary fixation is the method of choice for fractures of the femur, especially when there is no comminution and in cases of open fractures of the first and second degree. Rotation of fragments is locked, physical rehabilitation is faster and there is less risk of mal union.

Objective: The objective of the present study was to identify patterns of femoral diaphyseal fractures which are associated with fractures of the ipsilateral femoral neck according to the AO classification. We propose an algorithm of investigation based on plain radiographs, recognizing cases that need additional screening with computed tomography.Patients and Methods: This observational retrospective study included patients with combined diaphyseal and femoral neck fractures. These patients were retrieved from a total of 1398 patients with the diagnoses of diaphyseal fractures of the femur, who were admitted to our hospital for surgical treatment between January 2009 and October 2019. All included cases had both fractures analyzed for their geometry and were classified according to the AO Classification, seeking to find a correlation between the types of fractures.Results: Sixteen diaphyseal fractures associated with ipsilateral neck fractures were detected during the period. The distribution of the diaphyseal fractures according to the AO Classification was as follows: 5 of type A3 (31,2%) 6 type B2 (37.5%), 1 type B3 (6,2%), 2 type C2 (12,5%) and 2 type C3 (12,5%). One A2 femoral fracture occurred during the surgical procedure. No type A1 fractures were detected.Conclusion: The patterns of high-energy diaphyseal fractures (A3, B and C) have a higher prevalence of associated ipsilateral neck fractures. Our study suggests that routine additional methods of image investigation of femoral neck fractures may be unnecessary for diaphyseal fractures type A1 and A2.

BACKGROUND: Ipsilateral femoral shaft and neck fracture is a rare clinical injury, and its treatment has attracted more and more attention from scholars. At present, there are many internal fixation methods. OBJECTIVE: To retrospectively analyze efficacy of three internal fixation methods in the treatment of ipsilateral femoral shaft and neck fracture, and its indications. METHODS: Thirty-three cases of ipsilateral femoral neck and shaft fracture treated by three different internal fixation implants between January 2015 and September 2018 were retrospectively studied. Patients were divided into three groups according to different internal fixation: intramedullary nail only group (group A; n=11), retrograde nail with cannulated screw group (group B; n=10) and plate with cannulated screw group (group C; n=12). The general clinical data, the intraoperative situations, the postoperative follow-up conditions and complications were compared among the three groups. RESULTS AND CONCLUSION: (1) There was no significant difference between the three groups with regard to age, gender, cause of injury, AO fracture classification, Garden classification and average time from injury to surgery (P > 0.05). (2) There were statistically significant differences among the three groups in incision length (P < 0.05); no significant difference in incision length was found between the groups A and B (P > 0.05); the incision length was smaller in groups A and B than in group C (P < 0.05). There were no significant differences among the three groups in operation time and intraoperative blood loss (P > 0.05). (3) There were no significant differences among the three groups in time to bony union in both femoral shaft and neck, complication rate, and excellent and good rate of Harris hip score (P > 0.05). (4) Femoral neck fracture delayed healing occurred in one case of the group A; re-fracture occurred in one case of the group B; and the fracture end was located under the femoral tuberosity; screw loosening occurred in one case of the group C. (5) It is indicated that all three internal fixation methods can achieve good therapeutic effects. The operator can choose the skilled internal fixation method according to the specific conditions of the patient. [ABSTRACT FROM AUTHOR]

BACKGROUND: The use of elastic nails to treat children with unstable fractures or heavier children often results in shortening, angular or rotational deformities. OBJECTIVE: To provide a theoretical basis for internal fixation choice for femoral long oblique fracture by elastic nails combined with end caps or wire using biomechanical test. METHODS: An identical length oblique midshaft fracture was created in eight small adult cadaveric femurs harvested from four donors. Two 3.5-mm titanium elastic nails were introduced intramedullary into all femur models. According to the different fracture fixations, all models were divided into four groups (group A: titanium elastic nail, group B: titanium elastic nail+wire, group C: titanium elastic nail+caps, group D: titanium elastic nail+wire+caps). Nondestructive axial compression, four-point bending and torsion tests were conducted. Stiffness, displacement and torque were analyzed. RESULTS AND CONCLUSION: (1) In the axial compression tests, stiffness was increased by 509% and displacement was decreased by 74% using the titanium elastic nail+cap combination compared with titanium elastic nail alone (group A) (P < 0.01). (2) The titanium elastic nail+wire combination (group B) showed larger stiffness (P < 0.01) and smaller displacement (P < 0.01) in the sagittal plane bending test; and as well as larger stiffness (P < 0.01) and smaller displacement (P < 0.01) in coronal plane bending test; and larger stiffness in torsion test (P < 0.01). The end caps with wire in group D improved the stiffness significantly in all directions. (3) The results have demonstrated that end caps fixation helps to increase the axial stability of the long oblique fracture model, and combined wire fixation increases the structural stability under torsional and bending loads, which provides a good reference for clinical treatment of children with unstable femoral shaft fractures [ABSTRACT FROM AUTHOR]

Introduction: This study aims to evaluate the results of plate augmentation and bone grafting without removing the nail in the treatment of nonunited, nailed femoral shaft fractures. Methods: Twenty patients with atrophic nonunion femoral shaft fractures initially fixed by intramedullary nail were treated by augmentation plating and iliac bone graft with retention of the nail. Patients were evaluated at regular intervals using an X-ray and Wu scoring system, which assesses clinical and radiological signs of healing. Results: All 20 patients achieved bony union at a mean time of 4.9 months (3–8 months). According to Wu’s score, 12 cases showed excellent results, and 8 cases obtained good results with no complications recorded. Conclusion: augmentation plating and iliac bone graft provide a good and safe method of treatment of previously nailed and non-united femoral shaft fractures. Level of evidence: Level 4; Case Series.

Objective. To evaluate the outcome of TEN for the treatment of fracture of shaft of femur in pediatric age group. Method. 140 patients with diaphyseal femoral fracture were treated with retrograde Titanium elastic nail the age group 6-14 years. Two nails with same diameter were used in each fracture. The final result were evaluated using the criteria of Flynn et al. Results. The results were 102 (72.8%) excellent, 34 (24.2%) good, and 6 (3%) poor. Using the criteria of Flynn et al. All fractures were radiographically united at a median of 9 (6-11) w. The nails were removed after a median of 12 M postoperatively. The most common complication was irritation at nail insertion. Conclusion. TEN is an reliable, safe, and cost-effective implant for pediatric femoral fracture and it is an economic synthesis. It is relatively free of complication.

Fractures of the femur present some unique challenges to the treating orthopaedic surgeon. Non-accidental injury must always be considered. There are various modalities that can be used in the management of shaft fractures and these should be treated with careful consideration of not just the fracture pattern but also the patient's age, weight, bone maturity and social circumstances. Treatment options include: Pavlik harness, traction, spica casting, elastic nailing, sub-muscular plating, external fixation and intramedullary nailing. Selection of one treatment option over another should be done with full involvement of the patient and family. Femoral neck fractures, while rare, are associated with high-energy trauma and generally need to be treated as emergencies. Accurate anatomical reduction and fixation is crucial; despite this they have high rates of complications and these patients should be followed up for an extended period of time. [ABSTRACT FROM AUTHOR]

Femoral shaft fractures occur mainly due to high-energy traumas. To date, osteosynthesis represents the gold standard for the treatment of such fractures, and may be undertaken with a variety of stabilization methods: endomedullary nailing, plating, external fixation. However, there is no EBM literature unequivocally addressing a treatment for this topic. In order to appropriately treat femoral shaft fractures the authors believe it is essential to consider the pattern of lesion from an anatomo-pathological viewpoint, to evaluate the fracture pattern and put in relation to the patient's conditions, pointing out that surgical versatility, trauma experience and skills and the appropriateness in choosing the devices of synthesis is essential to approach such lesions.

Objective To explore the effect of long-term alcoholic gavage on the biomechanics of femoral shaft and femoral head in rats. Methods Thirty-five Sprague-Dawley rats were randomly divided into groups. Among them, 20 rats in the alcohol group received 46% alcohol for four times a week, and 15 rats in the blank group received an equal volume of normal saline. Four months later, the bilateral femoral head was subjected to a three-point bending test, and the bilateral femoral head was compressed. SPSS 23.0 software was used for statistical analysis. Results Compared with the blank group, the elastic parameters such as elastic modulus, stiffness coefficient, maximum load, and failure load of the femoral shaft in the alcohol group decreased, while the toughness coefficient, elastic strain, maximum strain, elastic deflection, and maximum deflection increased to varying degrees. All the differences were statistically significant (P<0.05). The elastic load and maximum load of the femoral head in the alcohol group decreased, and the differences were statistically significant (P<0.05). Conclusion Long-term alcohol intake reduces the biomechanical properties of the femoral shaft and femoral head in rats against external forces, which increases the risk of fracture.

Abstract Background Ipsilateral femoral shaft and neck fractures are rare injuries, affecting mostly young patients who sustained high-energy traumas. In 19–50% of cases, the femoral fracture is misdiagnosed or overlooked at the initial presentation, with reportedly increased risk of complications such as non-union and avascular necrosis. We present a case of an ipsilateral femoral neck and shaft fracture, which was missed at initial presentation despite radiographic and computed tomography (CT) scan evaluation. Case presentation A 56-year old female was admitted to our institution following a high-energy trauma (fall from 6 m). Initial radiographic and CT scan evaluation revealed a displaced femoral shaft fracture but no other femoral fractures were detected. Closed reduction and external fixation of the femoral shaft fracture was performed in the emergency setting. Follow-up radiologic evaluations revealed an ipsilateral laterally displaced femoral neck fracture. Despite cephalomedullary nail fixation of both fractures performed on the third day from the initial injury, the patient developed a non-union of the femoral neck fracture, which led to cut-out of the lag screw with associated varus failure of the femoral neck fracture requiring surgical revision and implant of a bipolar hemiarthroplasty at one year follow up. The postoperative course was uneventful and the patient had a full long-term recovery. Conclusion This case report exemplifies the need to maintain the highest level of suspiciousness for the concomitant presence of an ipsilateral femoral neck fracture when treating polytraumatized patients who sustained a femoral shaft fracture as a consequence of a high-energy trauma. Furthermore, the pre-operative standardized radiological evaluation (plain x-ray and CT scan) might not always help in ruling out these fractures. It is therefore necessary to adopt additional standardized radiographic protocols not only in the pre-operative but also in the intra-operative and immediate post-operative settings.

Background and Objective: A high percentage of patients with multiple traumas sustained at least from an orthopedic problem. One of the high frequent lesions was femoral shaft fracture. The aim of this study was to determine the amount of bleeding and the need for blood transfusion in femoral shaft fractures and risk factors. Methods: This descriptive, retrospective study was done on 84 patients with femoral shaft fractures whom were operated in Imam Khomeini Hospital in, Sari, in northern Iran during 2012-15. Age, sex, comorbidities, type of fracture, hospitalization period, pre and post-operative hemoglobin and blood unit's loss were recorded for each patient. Results: In 43 patients (51.19%) plate and in 41 patients (48.80%) intramedullary naling were used for treatment of fractures.13 (15.47%), 33 (39.28%) and 37(44.04%) of patients were received one, two and three blood units, respectively. There was no significant relationship between energy intensity and age. There was significant relationship between the intensity and the type of fracture (P

Objective: To explore clinical effect of attaching locking plate with bone grafting based on retaining the original intramedullary nail in treating non-union after intramedullary nail fixation of long shaft fractures of lower limbs., Methods: A retrospective study was conducted on 20 patients treated with non-union fractures after intramedullary nailing of long shaft fractures of lower limbs from June 2015 to June 2020. All patients were treated with the original intramedullary nailing and bone grafting from the iliac bone, and were underwent open reduction plate internal fixation and bone grafting for old fractures. Among them, 14 were males and 6 were females, aged from 35 to 56 years old with an average of (42.2±9.6) years old. Nine patients were femoral shaft fracture and 11 patients were tibial shaft fracture. According to characteristics of fracture end nonunion, 6 patients were stable/atrophic, 9 patients were unstable/large, and 5 patients were unstable/atrophic. The nonunion time ranged from 8 to 12 months with an average of(9.8±2.0) months after the initial surgery. Visual analogue scale (VAS), knee range of motion, bone healing time, complications and fracture-end healing were recorded before and at the latest follow-up., Results: All patients were followed up for 18 to 48 months with an average of (36.3±10.5) months. The incision of all patients were healed at stageⅠwithout complications such as infection or internal fixation ruptur. Healing time of femur and tibia was (8.5±2.6) months and (9.5±2.2) months. Knee joint motion increased from preoperative (101.05±8.98) ° to postoperative (139.35±8.78) ° at the latest follow-up ( t =-12.845, P <0.001). VAS decreased from preoperative (5.15±1.72) to postoperative (0.75±0.96) at the latest follow-up ( t =11.186, P <0.001)., Conclusion: On the basis of retaining the original intramedullary nail, the addition of locking plate internal fixation and autogenous iliac bone grafting have advantages of simple operation, less trauma, fewer complications and high fracture healing rate. It is one of the effective surgical schemes for the treatment of nonunion after intramedullary nail fixation of long bone fracture of lower extremity.

Background and purpose: One of the most important complications of bone fractures is nonunion. This research aimed at comparing the effect of exchange nailing and plate augmentation on complications after surgery and the time to achieve desired outcomes. Materials and methods: This descriptive-analytical study was conducted in12 femoral shaft nonunion case streated operatively in 2011-2018 (eight patients were managed with plate augmentation and four patients were treated with exchange nailing). Demographic characteristics of the patients, type of fracture and type of surgery were recorded. A year after the surgery, antero posterior and lateral view profiles were prepared from all patients and the extent of bone fusion was evaluated by orthopedic surgen. Results:Four patients (33.33%) underwent intraosseous nail replacement surgery and eight (66.67%) underwent plate augmentation surgery.Two patients (16.67%) developed infections and five (41.67%) had a short limb complication. The average limb shortness in these patients was 1.10±0.22 cm. The average duration of union after discharge was lower in patients with plate augmentation than those with replacement of the intramedullary nail.Conclusion:In current study, faster uninon achieved, so, augmentation plating could be a good choice in patients with femoral shaft nonunion.

Abstract Fractures of the femur present some unique challenges to the treating orthopaedic surgeon. Non-accidental injury must always be considered. There are various modalities that can be used in the management of shaft fractures and these should be treated with careful consideration of not just the fracture pattern but also the patient's age, weight, bone maturity and social circumstances. Treatment options include: Pavlik harness, traction, spica casting, elastic nailing, sub-muscular plating, external fixation and intramedullary nailing. Selection of one treatment option over another should be done with full involvement of the patient and family. Femoral neck fractures, whilst rare, are associated with high-energy trauma and generally need to be treated as emergencies. Accurate anatomical reduction and fixation is crucial; despite this they have high rates of complications and these patients should be followed up for an extended period of time.

Objective. To evaluate the outcome of TEN for the treatment of fracture of shaft of femur in pediatric age group. Method. 140 patients with diaphyseal femoral fracture were treated with retrograde Titanium elastic nail the age group 6-14 years. Two nails with same diameter were used in each fracture. The final result were evaluated using the criteria of Flynn et al. Results. The results were 102 (72.8%) excellent, 34 (24.2%) good, and 6 (3%) poor. Using the criteria of Flynn et al. All fractures were radiographically united at a median of 9 (6-11) w. The nails were removed after a median of 12 M postoperatively. The most common complication was irritation at nail insertion. Conclusion. TEN is an reliable, safe, and cost-effective implant for pediatric femoral fracture and it is an economic synthesis. It is relatively free of complication. [ABSTRACT FROM AUTHOR]

Of 11 047 pediatric patients with femoral shaft fractures, 8070 (73.1%) were male. The most common mechanisms of injury were falls (43.8%) and motor vehicle accidents (MVAs, 20.5%). The incidence of any associated injury was 58.3% for MVA patients and 6.2% for fall patients, while the overall incidence of any associated injury was 25.3%. The most common associated bony injuries for MVA patients occurred in the skull (14.1%) and tibia/fibula (13.7%), while lung injuries (22.3%) were the most frequent internal organ injuries. For comparison, these same three associated injuries for fall patients had incidences of 1.6%, 0.6%, and 0.5%, respectively. A multivariate analysis showed a significant association between having at least one associated injury and mortality, when controlling for age and gender. This study suggests that surveillance imaging studies, despite their associated radiation exposure, are warranted in this MVA subpopulation, especially since associated injuries are associated with increased mortality.

Introduction: Loading stress due to individual variations in femoral morphology is thought to be strongly associated with the pathogenesis of atypical femoral fracture (AFF). In Japan, studies on AFF regarding pathogenesis in the mid-shaft are well-documented and a key factor in the injury is thought to be femoral shaft bowing deformity. Thus, we developed a CT-based finite element analysis (CT/FEA) model to assess distribution of loading stress in the femoral shaft.Patients and Methods: A multicenter prospective study was performed at 12 hospitals in Japan from August 2015 to February 2017. We assembled three study groups-the mid-shaft AFF group (n=12), the subtrochanteric AFF group (n=10), and the control group (n=11)-and analyzed femoral morphology and loading stress in the femoral shaft by nonlinear CT/FEA.Results: Femoral bowing in the mid-shaft AFF group was significantly greater (lateral bowing, p<0.0001; anterior bowing, p<0.01). Femoral neck-shaft angle in the subtrochanteric AFF group was significantly smaller (p<0.001). On CT/FEA, both the mid-shaft and subtrochanteric AFF group showed maximum tensile stress located adjacent to the fracture site. Quantitatively, there was a correlation between femoral bowing and the ratio of tensile stress, which was calculated between the mid-shaft and subtrochanteric region (lateral bowing, r=0.6373, p<0.0001; anterior bowing, r=-0.5825, p<0.001).Conclusions: CT/FEA demonstrated that tensile stress by loading stress can cause AFF. The location of AFF injury could be determined by individual stress distribution influenced by femoral bowing and neck-shaft angle. [ABSTRACT FROM AUTHOR]
