Early Antibiotic Administration Is Associated with a Reduced Infection Risk When Combined with Primary Wound Closure in Patients with Open Tibia Fractures.

BACKGROUND: Early administration of antibiotics and wound coverage have been shown to decrease the deep infection risk in all patients with Type 3 open tibia fractures. However, it is unknown whether early antibiotic administration decreases infection risk in patients with Types 1, 2, and 3A open tibia fractures treated with primary wound closure. QUESTIONS/PURPOSES: (1) Does decreased time to administration of the first dose of antibiotics decrease the deep infection risk in all open tibia fractures with primary wound closure? (2) What patient demographic factors are associated with an increased deep infection risk in Types 1, 2, and 3A open tibia fractures with primary wound closure? METHODS: We identified 361 open tibia fractures over a 5-year period at a Level I regional trauma center that receives direct admissions and transfers from other hospitals which produces large variation in the timing of antibiotic administration. Patients were excluded if they were younger than 18 years, had associated plafond or plateau fractures, associated with compartment syndrome, had a delay of more than 24 hours from injury to the operating room, underwent repeat débridement procedures, had incomplete data, and were treated with negative-pressure dressings or other adjunct wound management strategies that would preclude primary closure. Primary closure was at the descretion of the treating surgeon. We included patients with a minimum follow-up of 6 weeks with assessment at 6 months and 12 months. One hundred forty-three patients with were included in the analysis. Our primary endpoint was deep infection as defined by the CDC criteria. We obtained chronological data, including the time to the first dose of antibiotics and time to surgical débridement from ambulance run sheets, transferring hospital records, and the electronic medical record to answer our first question. We considered demographics, American Society of Anesthesiologists classification, mechanism of injury, smoking status, presence of diabetes, and Injury Severity Score in our analysis of other factors. These were compared using one-way ANOVA, chi-square, or Fisher's exact tests. Binary regression was used to to ascertain whether any factors were associated with postoperative infection. Receiver operator characteristic curves were used to identify threshold values. RESULTS: Increased time to first administration of antibiotics was associated with an increased infection risk in patients who were treated with primary wound closure; the greatest inflection point on that analysis occurred at 150 minutes, when the increased infection risk was greatest (20% [8 of 41] versus 4% [3 of 86]; odds ratio 5.6 [95% CI 1.4 to 22.2]; p = 0.01). After controlling for potential confounding variables like age, diabetes and smoking status, none of the variables we evaluated were associated with an increased risk of deep infection in Type 1, 2, and 3A open tibia fractures in patients treated with primary wound closure. CONCLUSION: Our findings suggest that in open tibia fractures, which receive timely antibiotic administration, primary wound closure is associated with a decreased infection risk. We recognize that more definitive studies need to be performed to confirm these findings and confirm feasibility of early antibiotic administration, especially in the pre-hospital context.

Risk Factors for Transfusions Following Total Joint Arthroplasty in Patients With Rheumatoid Arthritis.

BACKGROUND/OBJECTIVE: Despite effective therapies, rheumatoid arthritis (RA) can result in joint destruction requiring total joint arthroplasty to maintain patient function. An estimated 16% to 70% of those undergoing total joint arthroplasty of the hip or knee will receive a blood transfusion. Few studies have described risk factors for blood transfusion following total joint arthroplasty in patients with RA. The aim of this study was to identify demographic and clinical risk factors associated with receiving a blood transfusion following total joint arthroplasty among patients with RA. METHODS: A retrospective study (n = 3270) was conducted using deidentified patient health claims information from a commercially insured, US data set (2007-2009). Data analysis included descriptive statistics and multivariate logistic regression. RESULTS: Females were more likely to receive a blood transfusion (odds ratio [OR], 1.48; 95% confidence interval [CI], 1.16-1.87; p = 0.001). When compared with those in the South, patients residing the Midwest were less likely to receive a blood transfusion following total joint arthroplasty (OR, 0.56; 95% CI, 0.44-0.71). Relative to those receiving total knee arthroplasty, patients who underwent total hip arthroplasty were more likely to receive a blood transfusion (OR, 1.39; 95% CI, 1.14-1.70), and patients who underwent a total shoulder arthroplasty were less likely to receive a blood transfusion (OR, 0.14; 95% CI, 0.05-0.38; p < 0.001). Patients with a history of anemia were more likely to receive a blood transfusion compared with those who did not have this diagnosis (OR, 3.30; 95% CI, 2.62-4.14; p < 0.001). CONCLUSIONS: Risk factors for the receipt of blood transfusions among RA patients who have undergone total joint arthroplasty were identified.

Using an Intraoperative Stress Exam to Direct Treatment in Posterior Femoral Head Fracture-Dislocations.

OBJECTIVE: To examine the results of a treatment algorithm incorporating an EUA performed intraoperatively after fixation of the femoral head through a Smith Petersen approach to determine need for posterior wall or capsule repair. METHODS: Design: Retrospective review. SETTING: Two Level 1 trauma centers. PATIENT SELECTION CRITERIA: All acute, traumatic femoral head fractures from posterior hip dislocations treated at participating centers over a 5-year period from 2017-2022. Injuries were classified according to the Pipkin system. OUTCOME MEASURES AND COMPARISONS: The primary outcome was the result of intraoperative EUA performed after femoral head fixation to determine the need for Kocher-Langenbeck exposure for posterior wall and/or capsule fixation. The secondary outcomes included rates of avascular necrosis, heterotopic bone formation, late instability, and conversion to total hip arthroplasty. RESULTS: Studied were 63 males and 22 females with mean age 32.5 (range 18-71). 79 of 85 (92.9%) patients had a stable EUA after fixation of the femoral head through a Smith-Petersen approach. Six (6/85, 7.1%) underwent an additional Kocher-Langenbeck approach for posterior wall or capsule fixation. This included 1 Pipkin I, 1 Pipkin II, and 4 Pipkin IV injuries. Of the Pipkin IV injuries, 51/55 (92.7%) had stable EUA and did not require fixation of their posterior wall. This included 7 patients with wall involvement >20%. Five patients were excluded because of planned fixation of their posterior wall based on preoperative imaging. Of patients with at least 6 months follow up, 16 of 65 (26.4%) developed radiographic evidence of AVN and 21 of 65 (32.3%) evidence of heterotopic bone formation. Seven out of 65 (10.8%) were converted to total hip arthroplasty over the study period. When comparing patients with a single exposure with those with additional KL exposure, they did not vary in their rate of AVN (27.1% vs. 0.0%, P=0.3228), HO formation (30.5% vs. 50.0%, P=0.3788), or conversion to total hip arthroplasty (10.2% vs. 16.7%, P=0.510). CONCLUSIONS: This study found residual posterior hip instability after femoral head fixation in patients with and without posterior wall fractures after posterior dislocations. The results of this study support use of an EUA after femoral head fixation to identify residual posterior hip instability in all femoral head fractures from posterior hip dislocations, regardless of Pipkin type. Use of the Smith-Petersen exposure remains a viable surgical option and may be improved with incorporation of an EUA after femoral head fixation. For Pipkin IV injuries with posterior wall fractures with indeterminate stability, an EUA accurately identifies residual instability. LEVEL OF EVIDENCE: Therapeutic Level III.

Nonoperative Treatment of Humeral Shaft Fractures With Immediate Functional Bracing Versus Coaptation Splinting and Delayed Functional Bracing: A Retrospective Study.

OBJECTIVES: To compare radiographic and clinical outcomes in nonoperative management of humeral shaft fractures treated initially with coaptation splinting (CS) followed by delayed functional bracing (FB) versus treatment with immediate FB. DESIGN: Retrospective cohort study. SETTING: Academic Level 1 Trauma Center. PATIENT SELECTION CRITERIA: Patients with closed humeral shaft fractures managed nonoperatively with initial CS followed by delayed FB or with immediate FB from 2016 to 2022. Patients younger than 18 years and/or with less than 3 months of follow-up were excluded. OUTCOME MEASURES AND COMPARISONS: The primary outcome was coronal and sagittal radiographic alignment assessed at the final follow-up. Secondary outcomes included rate of failure of nonoperative management (defined as surgical conversion and/or fracture nonunion), fracture union, and skin complications secondary to splint/brace wear. RESULTS: Ninety-seven patients were managed nonoperatively with delayed FB (n = 58) or immediate FB (n = 39). Overall, the mean age was 49.9 years (range 18-94 years), and 64 (66%) patients were female. The immediate FB group had less smokers ( P = 0.003) and lower incidence of radial nerve palsy ( P = 0.025), with more proximal third humeral shaft fractures ( P = 0.001). There were no other significant differences in demographic or clinical characteristics ( P > 0.05). There were no significant differences in coronal ( P = 0.144) or sagittal ( P = 0.763) radiographic alignment between the groups. In total, 33 (34.0%) humeral shaft fractures failed nonoperative management, with 11 (28.2%) in the immediate FB group and 22 (37.9%) in the delayed FB group ( P = 0.322). There were no significant differences in fracture union ( P = 0.074) or skin complications ( P = 0.259) between the groups. CONCLUSIONS: This study demonstrated that nonoperative treatment of humeral shaft fractures with immediate functional bracing did not result in significantly different radiographic or clinical outcomes compared to treatment with CS followed by delayed functional bracing. Future prospective studies assessing patient-reported outcomes will further guide clinical decision making. LEVEL OF EVIDENCE: Therapeutic Level III.

Does Local Aqueous Tobramycin Injection Reduce Open Fracture-Related Infection Rates?

OBJECTIVES: To examine the effect of local aqueous tobramycin injection adjunct to perioperative intravenous (IV) antibiotic prophylaxis in reducing fracture-related infections (FRIs) following reduction and internal fixation of open fractures. DESIGN: Retrospective cohort study. SETTING: Single academic Level I trauma center. PATIENTS SELECTION CRITERIA: Patients with open extremity fractures treated with reduction and internal fixation with (intervention group) or without (control group) 80 mg of local aqueous (2 mg/mL) tobramycin injected during closure at the time of definitive fixation were identified from December 2018 to August 2021 based on population-matched demographic and injury characteristics. OUTCOME MEASURES AND COMPARISONS: The primary outcome was FRI within 6 months of definitive fixation. Secondary outcomes consisted of fracture nonunion and bacterial speciation. Differences in outcomes between the 2 groups were assessed and logistic regression models were created to assess the difference in infection rates between groups, with and without controlling for potential confounding variables, such as sex, fracture location, and Gustilo-Anderson classification. RESULTS: An analysis of 157 patients was performed with 78 patients in the intervention group and 79 patients in the control group. In the intervention group, 30 (38.5%) patients were women with a mean age of 47.1 years. In the control group, 42 (53.2%) patients were women with a mean age of 46.4 years. The FRI rate was 11.5% in the intervention group compared with 25.3% in the control group ( P = 0.026). After controlling for sex, Gustilo-Anderson classification, and fracture location, the difference in FRI rates between groups remained significantly different ( P = 0.014). CONCLUSIONS: Local aqueous tobramycin injection at the time of definitive internal fixation of open extremity fractures was associated with a significant reduction in FRI rates when administered as an adjunct to intravenous antibiotics, even after controlling for potential confounding variables.

Radiation Exposure Among Orthopaedic Trauma Surgeons: Deconstructing Commonly Held Myths and Misperceptions.

OBJECTIVES: To review and evaluate the validity of common perceptions and practices regarding radiation safety in orthopaedic trauma. DESIGN: Retrospective study. SETTING: Level 1 trauma center. SUBJECTS: N/A. INTERVENTION: The intervention involved personal protective equipment. MAIN OUTCOME MEASUREMENTS: The main outcome measurements included radiation dose estimates. RESULTS: Surgeon radiation exposure estimates performed at the level of the thyroid, chest, and pelvis demonstrate an estimated total annual exposure of 1521 mR, 2452 mR, and 1129 mR, respectively. In all cases, wearing lead provides a significant reduction (90% or better) in the amount of radiation exposure (in both radiation risk and levels of radiation reaching the body) received by the surgeon. Surgeons are inadequately protected from radiation exposure with noncircumferential lead. The commonly accepted notion that there is negligible exposure when standing greater than 6 feet from the radiation source is misleading, particularly when cumulative exposure is considered. Finally, we demonstrated that trauma surgeons specializing in pelvis and acetabular fracture care are at an increased risk of exposure to potentially dangerous levels of radiation, given the amount of radiation required for their caseload. CONCLUSION: Common myths and misperceptions regarding radiation in orthopaedic trauma are unfounded. Proper use of circumferential personal protective equipment is critical in preventing excess radiation exposure.

Is the Presence of a Psychiatric Disorder Associated With More Aggressive Management of Compartment Syndrome?

OBJECTIVE: To determine whether pre-existing psychiatric disorder is associated with potentially unnecessary fasciotomy. DESIGN: Retrospective cohort study. SETTING: Academic Level-1 trauma center. PATIENTS: All the patients with orthopaedic trauma undergoing leg fasciotomy at an academic Level I trauma center from 2006 to 2020. INTERVENTION: Pre-existing diagnosis of psychiatric disorder. MAIN OUTCOME MEASUREMENTS: Early primary wound closure and delayed primary wound closure. RESULTS: In total, 116 patients were included. Twenty-seven patients (23%) had a pre-existing diagnosis of psychiatric disorder with 13 having anxiety, 14 depression, 5 bipolar disorder, and 2 ADHD. Several patients had multiple diagnoses. Fifty-one patients (44%) had early primary closure (EPC), and 65 patients (56%) had delayed primary closure. Of patients with a psychiatric disorder, 52% received EPC compared with 42% of patients without a disorder, P = 0.38. This lack of a strong association did not seem to vary across specific psychiatric conditions. After adjusting for sex, age, injury type, and substance abuse, there was still no significant association between a psychiatric disorder and EPC with an odds ratio of 1.08 (95% CI, 0.43-2.75). CONCLUSIONS: Among patients with orthopaedic trauma undergoing emergent fasciotomy for acute compartment syndrome, a psychiatric disorder was not associated with a significantly increased rate of possibly unnecessary fasciotomy. Given the potential for a psychiatric condition to complicate the diagnosis of acute compartment syndrome, this data is somewhat reassuring; however, there remains a need for continued vigilance in treating patients with psychiatric conditions and research in this area.

Predictions of U.K. regulated power station contributions to regional air pollution and deposition: a model comparison exercise.

Contributions of the emissions from a U.K. regulated fossil-fuel power station to regional air pollution and deposition are estimated using four air quality modeling systems for the year 2003. The modeling systems vary in complexity and emphasis in the way they treat atmospheric and chemical processes, and include the Community Multiscale Air Quality (CMAQ) modeling system in its versions 4.6 and 4.7, a nested modeling system that combines long- and short-range impacts (referred to as TRACK-ADMS [Trajectory Model with Atmospheric Chemical Kinetics-Atmospheric Dispersion Modelling System]), and the Fine Resolution Atmospheric Multi-pollutant Exchange (FRAME) model. An evaluation of the baseline calculations against U.K. monitoring network data is performed. The CMAQ modeling system version 4.6 data set is selected as the reference data set for the model footprint comparison. The annual mean air concentration and total deposition footprints are summarized for each modeling system. The footprints of the power station emissions can account for a significant fraction of the local impacts for some species (e.g., more than 50% for SO2 air concentration and non-sea-salt sulfur deposition close to the source) for 2003. The spatial correlation and the coefficient of variation of the root mean square error (CVRMSE) are calculated between each model footprint and that calculated by the CMAQ modeling system version 4.6. The correlation coefficient quantifies model agreement in terms of spatial patterns, and the CVRMSE measures the magnitude of the difference between model footprints. Possible reasons for the differences between model results are discussed. Finally, implications and recommendations for the regulatory assessment of the impact of major industrial sources using regional air quality modeling systems are discussed in the light of results from this case study.

Increase in Osteoporotic U-Type Sacral Fractures: Role of the Transiliac-Transsacral Screw Versus Lumbopelvic Fixation.

SUMMARY: As the population is increasing in age, so increases the number of osteoporotic fractures. U-shaped sacral fractures can be difficult to diagnose and may be a source of disability in patients when left untreated. Many patients with osteoporotic fractures are of advanced age and may experience rapid medical decline when these fractures cause immobility. We present surgical options for U-shaped sacral fracture management.

Factors Associated With Failure of Superior Pubic Ramus Screws.

OBJECTIVE: Examine factors associated with fixation failure in patients treated with superior intramedullary ramus screws. DESIGN: Retrospective. SETTING: Single, Level 1 trauma center. PATIENTS: Unstable pelvic ring fractures amenable fixation that included superior intramedullary ramus screws. INTERVENTION: Percutaneously inserted intramedullary superior ramus screw fixation of superior pubic ramus (SPR) fractures. MAIN OUTCOME MEASUREMENTS: Loss of reduction (LOR) of the SPR fracture defined as >2 mm displacement on pelvic radiographs at any time point in follow-up. RESULTS: Two hundred eighty-five fractures in 211 patients (age 44, 95% confidence interval 40.8%-46.4%, 59.3% women, 55.1% retrograde screws) were included in the analysis. 14 (4.9%) of fractures had LOR. Patients were significantly more likely to have LOR as age increased (P = 0.01), body mass index (BMI) increased (P = 0.01), and if they were women (P < 0.01). There was a significantly decreased LOR (P < 0.01) as fractures moved further from the pubis symphysis. Retrograde screws were significantly (P < 0.01) more likely to have LOR. In SPR fractures treated with retrograde screws, failure was significantly associated with increasing BMI (P = 0.02), the presence of an inferior ramus fracture (P = 0.02), and trended toward significance with increasing age (P = 0.06), and decreased distance from the symphysis (P = 0.07). CONCLUSIONS: Superior ramus screws are associated with a low failure rate (4.9%), which is lower than previously reported. Retrograde screw insertion, distance from the symphysis, increasing age, increasing BMI, decreased distance from the symphysis, and ipsilateral inferior ramus fractures were predictors of failure. In these patients, alternative modalities should be considered, although low rates of failure can still be expected. LEVEL OF EVIDENCE: Therapeutic Level IV.

Comparison of 3 C-Arm Draping Techniques to Prevent Far Side Contamination.

OBJECTIVE: To assess the effectiveness of reducing contamination using 2 methods of C-Arm draping compared with traditional methods. MATERIALS AND METHODS: The authors simulated an operating room using an extremity drape, commercially available C-Arm drapes, and C-Arm. A black light was placed above the field. A fluorescent powder was placed on the nonsterile portions of the field. Baseline light intensity was recorded by photo. The C-Arm was brought into the surgical field for orthogonal imaging for 15 cycles. A repeat photograph was taken to measure the increase in intensity of the fluorescent powder to assess degree of contamination. This was repeated 5 times for each configuration: standard C-Arm drape, a proprietary close-fitting drape, and a split drape secured to the far side with the split wrapped around the C-Arm receiver. Light intensity difference was measured and average change in intensity was compared. RESULTS: Compared with standard draping, the proprietary close-fitting drape resulted in a 71.3% decrease in contamination (4.84% vs. 16.90%, P = 0.101) that trended toward significance and the split drape resulted in a 99.5% decrease (0.09% vs. 16.90%, P = 0.017) that was statistically significant. CONCLUSION: Far side contamination can be reduced by using a split drape connecting the operative table to the C-Arm receiver, effectively "sealing off" contaminants. The proprietary close-fitting drape may also decrease contamination, but this was not statistically significant in this study. Use of the split drape technique will help prevent contamination and may ultimately lead to decreased infection risk.

Newer generation of proximal tibia locking plates demonstrate large variability in their ability to capture the posteromedial fragment in bicondylar tibial plateau fractures.

INTRODUCTION: The early generations of proximal tibial locking plates demonstrated inferior results when compared to dual plating in bicondylar tibial plateau fractures with posteromedial fragments (PMF). Modern plates have multiple rows of locking screws and variable angle technology -which tote the ability to capture the PMF. The purpose of this study was to determine if the modern plates could capture the PMF in a large series of bicondylar tibial plateau fractures. MATERIALS & METHODS: Axial computer topography (CT) scans of 114 bicondylar tibial plateau fractures with PMF were analyzed. Five proximal tibia locking plates-in seven total configurations-were applied to radiopaque tibiae models. All possible screws were placed. Templates of screw trajectories were created based on the model CT scans. These were superimposed onto patient CT scan images to assess for screw penetration into the PMF. Number of screws fully within the PMF were recorded. Capture of the PMF was defined as having at least two screws within the fragment. RESULTS: On average, all plates were able to capture 81.6% of PMF with an average of 3.77 [95% Confidence Interval (CI): 3.47-4.07] screws. However, their ability to capture all fragments varied greatly, from 55.7%-95.2% in fixed angle constructs. Overall, variable angle constructs had a significantly higher capture rate (98.5% vs. 74.9%; p<0.0001) and more screws in the PMF (5.88 [95% CI: 5.58-6.17] vs 2.93 [95% CI: 2.62-3.24]; p<0.0001) when compared to fixed angle constructs. CONCLUSION: Newer generation locking plates vary greatly in their ability to capture the PMF. Variable angle technology dramatically increases the ability to capture the majority of PMFs. Prior biomechanical and clinical studies may yield substantially different results if repeated with these newer implants. Use of newer generation locked plates should not replace thorough preoperative planning.

The Learning Curve of Suprapatellar Nailing: Adoption Over Time Can Decrease Operative Time and Radiation Exposure.

OBJECTIVE: To determine whether suprapatellar nailing (SPN) over time can decrease operative time and radiation exposure when compared with infrapatellar nailing (IPN) of tibial shaft fractures. DESIGN: Retrospective. SETTING: Single, Level 1 trauma center. PATIENTS: Extra-articular adult tibial shaft fractures treated with intramedullary nailing alone within a 7-year period. INTERVENTION: Patients were treated with SPN or IPN techniques based on the discretion of the operating surgeon. MAIN OUTCOME MEASUREMENTS: Operative time and radiation exposure. RESULTS: Three hundred forty-one fractures (SPN: 177, IPN: 164) were included in the analysis. No differences in patient body mass index, sex, or open fracture incidence existed between the 2 groups. A significant difference in average operative time (IPN 130 minutes vs. SPN 110 minutes, P < 0.01), fluoroscopy time (IPN 159 minutes vs. SPN 143 minutes, P = 0.02), and radiation dose (IPN 8.6 mGy vs. SPN 6.5 mGy, P < 0.01) existed between IPN and SPN. Early tibias treated with SPN had similar operative times (P = 0.11), fluoroscopy time (P = 0.94), and radiation dose (P = 0.34) compared with IPN. Later SPN patients had significantly lower operative time (P = 0.03), fluoroscopy time (P < 0.01), and radiation dose (P < 0.013) compared with earlier SPN. Regression analysis revealed with the increased use of SPN, operative time, fluoroscopy time, and radiation dose significantly decreased (P = 0.018, 0.046, 0.011). CONCLUSIONS: Tibia fractures treated with SPN have significantly decreased operative times and radiation exposure compared with those treated with IPN, after allowing time for the surgeon to gain sufficient experience with the technique. The surgeon should consider this when deciding to adopt this technique. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Intraoperative Assessment of Coronal Alignment in Distal Femur Fracture Fixation: Technical Trick.

Supracondylar femur fractures represent a challenging and common injury treated by many orthopedic surgeons. An array of surgical fixation options has been developed to help the treating surgeon restore normal anatomic alignment of these fractures, and lateral precontoured condylar femoral locking plates have become a common implant for most surgeons in treating these fractures. Although these precontoured plates provide significant benefit to the treating physician in regards to gaining appropriate bony fixation, common technical errors that may lead to malalignment when using these plates have been described. Avoiding these errors will help improve patient outcomes. Here, we describe a novel, inexpensive, and universally available technique that may aid the treating surgeon in restoring coronal alignment when treating distal femur fractures.

Indications for Open Reduction Internal Fixation of Anterior Pelvic Ring Disruptions.

In acute trauma, pelvic ring instability can lead to hemorrhage and hemodynamic instability. Pelvic ring instability and displacement that is not stabilized may lead to chronic pain, sitting imbalance, and limb length inequality. Methods and timing of securing anterior pelvic ring injuries operatively is controversial and debatable. Many orthopaedic trauma surgeons would agree that acceptable methods to treat a disrupted anterior pelvic ring fracture include nonoperative care, external fixation, internal spanning fixators, intramedullary superior ramus screws, and open reduction internal fixation. We will review the indications for open reduction internal fixation fractures and disruptions of the anterior pelvic ring.

Femoroacetabular impingement as a complication of acetabular fracture fixation.

CASE: We present the case of a thirteen-year-old female who sustained a posterior wall acetabular fracture dislocation. She underwent urgent closed reduction and subsequent uncomplicated open reduction and internal fixation. Post reduction computed tomography demonstrated a concentrically reduced hip joint with no evidence of femoroacetabular impingement (FAI). She subsequently healed her fracture and returned to running activities; however, one year later presented with aching pain in her thigh. Radiographs demonstrated the development of a large osseous prominence on her anterolateral femoral neck consistent with femoroacetabular impingement. Based on these findings she was evaluated by a hip preservation specialist. She subsequently underwent successful hip arthroscopy for labral repair and femoral osteochondroplasty. She was eventually able to return to running sports with little pain. SUMMARY: We present a case of FAI presenting as a complication of acetabular fracture fixation. This should be discussed with patients presenting with traumatic hip dislocations as a possible complication of surgical fixation or possibly of the injury itself.

Delayed Presentation of Compartment Syndrome of the Thigh in a Previously Undiagnosed Factor VII-Deficient High School Football Athlete: A Case Report.

CASE: We describe a case of delayed presentation of compartment syndrome in the anterior aspect of the thigh in a high school athlete. The patient had sustained a blow to the thigh 8 days prior to presentation, and had continued to practice football in the setting of undiagnosed coagulopathy. He presented with severe thigh pain and the inability to contract the thigh muscles. CONCLUSION: A high index of suspicion for compartment syndrome is indicated for patients with disproportionate pain, especially in the setting of relatively minor trauma. Underlying coagulopathy should be investigated in patients with compartment syndrome because there is a high incidence of bleeding disorders in this population.

Intraoperative use of the pelvic c-clamp as an aid in reduction for posterior sacroiliac fixation.

Posterior pelvic ring injuries with dissociation of the sacroiliac joint can be a therapeutic challenge. Open procedures for reduction have a significant risk for wound complications although inadequate reductions using percutaneous methods can have poor long-term outcomes. Several indirect reduction methods have been previously described for closed reduction of the sacroiliac joint. We present our technique for the intraoperative use of the pelvic c-clamp as a reduction aid for the posterior pelvis in conjunction with percutaneous iliosacral screw fixation. This technique has been used routinely in our patients who sustain injuries to the sacroiliac joint and are candidates for closed reduction and percutaneous fixation. Our objective is to provide orthopedic surgeons an additional means by which to reduce sacroiliac disruptions by percutaneous means.
