Project description:A 39-year-old male presented with multiple gunshot wounds and resultant left comminuted femoral head and neck fractures with retained intraarticular bullet fragments. Successful staged reconstruction was performed with initial placement of an antibiotic spacer and subsequent conversion to total hip arthroplasty. Staged reconstruction with an antibiotic spacer and conversion to total hip arthroplasty is a viable treatment approach for a gunshot wound resulting in intraarticular bullet fragments and comminuted femoral head and neck fractures not amenable to open reduction and internal fixation to reduce the risk of periprosthetic joint infection.

Project description:ObjectiveTo compare the functional results after displaced fractures of the femoral neck treated with internal fixation or hemiarthroplasty.DesignRandomised trial with blinding of assessments of functional results.SettingUniversity hospital.Participants222 patients; 165 (74%) women, mean age 83 years. Inclusion criteria were age above 60, ability to walk before the fracture, and no major hip pathology, regardless of cognitive function.InterventionsClosed reduction and two parallel screws (112 patients) and bipolar cemented hemiarthroplasty (110 patients). Follow-up at 4, 12, and 24 months.Main outcome measuresHip function (Harris hip score), health related quality of life (Eq-5d), activities of daily living (Barthel index). In all cases high scores indicate better function.ResultsMean Harris hip score in the hemiarthroplasty group was 8.2 points higher (95% confidence interval 2.8 to 13.5 points, P=0.003) at four months and 6.7 points (1.5 to 11.9 points, P=0.01) higher at 12 months. Mean Eq-5d index score at 24 months was 0.13 higher in the hemiarthroplasty group (0.01 to 0.25, P=0.03). The Eq-5d visual analogue scale was 8.7 points higher in the hemiarthroplasty group after 4 months (1.9 to 15.6, P=0.01). After 12 and 24 months the percentage scoring 95 or 100 on the Barthel index was higher in the hemiarthroplasty group (relative risk 0.67, 0.47 to 0.95, P=0.02. and 0.63, 0.42 to 0.94, P=0.02, respectively). Complications occurred in 56 (50%) patients in the internal fixation group and 16 (15%) in the hemiarthroplasty group (3.44, 2.11 to 5.60, P<0.001). In each group 39 patients (35%) died within 24 months (0.98, 0.69 to 1.40, P=0.92)ConclusionsHemiarthroplasty is associated with better functional outcome than internal fixation in treatment of displaced fractures of the femoral neck in elderly patients.Trial registrationNCT00464230.

Project description:Botulism developed in a patient following surgical repair of an open radial fracture. Symptoms resolved after treatment with antitoxin and antibiotics, and hardware excision was deferred. Subsequent osteomyelitis necessitated hardware exchange, and wound cultures grew Clostridium argentinense. This case highlights the management of botulism associated with orthopedic hardware.

Project description:We present a case of a bisphosphonate-related femur fracture in an elderly woman, who failed treatment with both cephalomedullary nail and proximal femoral locking plate, leading to successful treatment with total hip arthroplasty. Hardware failure should be included in the differential of patients with previous internal fixation of bisphosphonate-related femur fracture that present with hip or groin pain. Arthroplasty can be an acceptable salvage option in an active elderly patient with a bisphosphonate-related femur fracture.

Project description:PurposePrevious studies have proved that vascular endothelial growth factor (VEGF) has a dual role in the promotion of new bone formation and blood vessel repair during fracture healing. However, how to introduce VEGF to a fracture site safely and effectively is still a challenge. This study aimed to prepare a VEGF-loaded nanographene coated internal fixation screw and to evaluate its effects in the treatment of femoral neck fracture.MethodsNanographene coated screws were prepared by direct liquid-phase exfoliation of the graphite method, and the surface characteristics were observed through scanning electron microscopy (SEM). VEGF was loaded on nanographene coatings through physical adsorption, and the VEGF controlled release was examined by ELISA. Then a canine femoral neck fracture model was built to examine both the angiogenic and osteogenic properties of the VEGF-loaded coated screws. X-ray, micro-CT-based microangiography, and histopathologic evaluation were used to assess the fracture healing progress.ResultsThe results demonstrated that nanographene could load VEGF effectively, and the accumulative release of VEGF clearly increased during the entire testing period (9 days) without burst release. In canine fracture models, the results of X-ray, microangiography, and histopathologic examination proved that the speed of fracture healing, new bone formation area, and revascularization of the fractured femoral heads in the VEGF-loaded coated screws groups were significantly higher than in the control groups.ConclusionOur study proved that VEGF-loaded nanographene coated screws were effective in the treatment of femoral neck fracture and prevention of avascular necrosis of femoral head.

Project description:BackgroundFractures of the femoral shaft are common and have potentially serious consequences in patients with multiple injuries. The appropriate timing of fracture repair is controversial. The purpose of the present study was to assess the effect of timing of internal fixation on mortality in patients with multisystem trauma.MethodsWe performed a retrospective cohort study with use of data from public and private trauma centers throughout the United States that were reported to the National Trauma Data Bank (version 5.0 for 2000 through 2004). The study included 3069 patients with multisystem trauma (Injury Severity Score, > or =15) who underwent internal fixation of a femoral shaft fracture. The time to treatment was defined in categories as the time from admission to internal fixation: t(0) (twelve hours or less), t(1) (more than twelve hours to twenty-four hours), t(2) (more than twenty-four hours to forty-eight hours), t(3) (more than forty-eight hours to 120 hours), and t(4) (more than 120 hours). The relative risk of in-hospital mortality when the four later periods were compared with the earliest one was estimated with inverse probability of treatment-weighted analysis. Subgroups with serious head or neck, chest, abdominal, and additional extremity injury were investigated.ResultsWhen compared with that during the first twelve hours after admission, the estimated mortality risk was significantly lower in three time categories: t(1) (relative risk, 0.45; 95% confidence interval, 0.15 to 0.98; p = 0.03), t(3) (relative risk, 0.58; 95% confidence interval, 0.28 to 0.93; p = 0.03), and t(4) (relative risk, 0.43; 95% confidence interval, 0.10 to 0.94; p = 0.03). Patients with serious abdominal trauma (Abbreviated Injury Score, > or =3) experienced the greatest benefit from a delay of internal fixation beyond twelve hours (relative risk, 0.82 [95% confidence interval, 0.54 to 1.35] for patients with an Abbreviated Injury Score of <3, compared with 0.36 [95% confidence interval, 0.13 to 0.87] for those with an Abbreviated Injury Score of > or =3) (p value for effect modification, 0.09).ConclusionsDelayed repair of femoral shaft fracture beyond twelve hours in patients with multisystem trauma, which may allow time for appropriate resuscitation, reduces mortality by approximately 50%. Patients with serious abdominal injury benefit most from delayed treatment. These results support delaying definitive treatment of long-bone injuries in patients with multisystem trauma as a means of so-called damage-control in order to reduce adverse outcomes.

Project description:Femoral head fractures after posterior dislocation of the hip are uncommon and are conventionally treated by an open method. Hip arthroscopy can be a valuable treatment option for the management of femoral head fractures. Arthroscopy allows for a less invasive option when compared with arthrotomy and can allow faster recovery with minimal soft-tissue injury. We describe the arthroscopic reduction and internal fixation of Pipkin type I femoral head fractures with a detailed stepwise description of the surgical technique, including technical pearls and pitfalls, potential complications, and advantages and disadvantages.

Project description:This is a study of femoral fracture healing in female rats 16 weeks old at fracture to compare intramedullary nailing, screw and plate fixation, and sham surgery. The sham surgery group received a surgical exposure of the femur, but no fracture, no plate, and no nail. Samples were collected at 1 day, 3 days, 1 week, 2 weeks, 4 weeks, and 6 weeks after surgery. Each sample is a pool of RNA from three rats from the same surgery group at the same time point after fracture. The middle third of the femur was collected with the cortical bone, fracture callus, and marrow elements. Mid-diaphyseal, simple, transverse fractures were induced by a Gigli saw. The no fracture sample was a time 0 control collected on the day of surgery from intact rats.

Project description:BACKGROUND:Femoral neck fractures are common fractures in the elderly. Common treatment options include internal fixation (IF) and hemiarthroplasty (HA). However, the clinical application of these two options is always controversial due to the potential clinical trauma, postoperative function, early complications, and other factors. MATERIALS AND METHODS:Randomized controlled trials and cohort studies comparing screw fixation and hemiarthroplasty in elderly patients with displaced femoral neck fractures were extracted from databases such as PubMed, Web of Science, EMBASE, and Cochrane. The revised Jadad scale or NOS treatment evaluation form was used to evaluate the quality of the included studies. After extracting the data, the standard deviation of continuous data and the relative risk of binary data were used. The operation time, blood loss during operation, EQ-5D (EuroQol-5 Dimension) score, mortality rate, reoperation rate, and postoperative common complications were reviewed using Review Manager software (RevMan 5.3) were compared. RESULTS:There were 7 randomized controlled trials and 5 cohort studies. The results showed that the operation time, intraoperative blood loss, and short-term EQ-5D score of the internal fixation group were lower than those of the hemi-hip replacement group, but the reoperation rate was higher. There was no statistically significant difference in mortality and common complications such as deep vein thrombosis, pulmonary embolism, infection, and pressure sores during short-term follow-up. CONCLUSIONS:In the treatment of elderly femoral neck fractures, the screw internal fixation group has shorter operation time and less intraoperative bleeding, and the perioperative advantage is more obvious. However, the hemi-hip replacement group had more advantages in postoperative functional scoring and reoperation.

Project description:ObjectivesTo determine patient independency, health-related and disease-specific quality of life (QOL), gait pattern, and muscle strength in patients after salvage arthroplasty for failed internal fixation of a femoral neck fracture.DesignSecondary cohort study to a randomized controlled trial.SettingMulticenter trial in the Netherlands, including 14 academic and nonacademic hospitals.PatientsPatients after salvage arthroplasty for failed internal fixation of a femoral neck fracture were studied. A comparison was made with patients who healed uneventfully after internal fixation.InterventionNone (observatory study).Main outcome measurementsPatient characteristics, SF-12, and Western Ontario McMaster osteoarthritis index scores were collected. Gait parameters were measured using plantar pressure measurement. Maximum isometric forces of the hip muscles were measured using a handheld dynamometer. Differences between the fractured and contralateral leg were calculated. Groups were compared using univariate analysis.ResultsOf 248 internal fixation patients (median age, 72 years), salvage arthroplasty was performed in 68 patients (27%). Salvage arthroplasty patients had a significantly lower Western Ontario McMaster osteoarthritis index score (median, 73 vs. 90; P = 0.016) than patients who healed uneventfully after internal fixation. Health-related QOL (SF-12) and patient independency did not differ significantly between the groups. Gait analysis showed a significantly impaired progression of the center of pressure in the salvage surgery patients (median ratio, -8.9 vs. 0.4, P = 0.013) and a significant greater loss of abduction strength (median, -25.4 vs. -20.4 N, P = 0.025).ConclusionsDespite a similar level of dependency and QOL, salvage arthroplasty patients have inferior functional outcome than patients who heal after internal fixation of a femoral neck fracture.Level of evidenceTherapeutic level III.
