The pivot fracture: an unusual tibial plateau fracture found in association with acute ACL injury.

Tibial plateau fractures are common fractures which are often associated with concurrent soft tissue injury and for which accurate preoperative diagnosis is important for development of an appropriate treatment plan and outcome prediction. Here, we present an extreme manifestation of the pivot shift phenomenon with an unusual tibial plateau fracture with flipped component not described by any existing tibial plateau fracture classification system and never reported previously in conjunction with an anterior cruciate ligament injury. We describe the utilization of advanced imaging not typically utilized in the management of tibial plateau fractures in combination with clinical suspicion to diagnose the associated soft tissue injuries and develop an appropriate management plan.

Dislocation is a risk factor for poor outcome after supination external rotation type ankle fractures.

INTRODUCTION: Ankle fractures are one of the most common fractures requiring surgical treatment. Ankle fracture-dislocations are significant injuries to the osseous and soft tissue envelope, but studies focused on the effect of dislocation on radiographic and functional outcomes are lacking. The objective of this study was to evaluate the effect of dislocations on postoperative outcomes in SER IV ankle fracture patients. MATERIALS AND METHODS: From 2004 through 2010, all operative SER IV ankle fractures treated by a single surgeon were enrolled in a prospective database. SER IV ankle fractures were separated into two groups based on clinical or radiographic evidence of dislocation. The primary and secondary functional outcomes measures were the Foot and Ankle Outcome Score (FAOS) and ankle and subtalar range of motion (ROM) with a minimum of 1-year follow-up, respectively. RESULTS: 108 patients with SER IV ankle fractures were identified, with 73 in the non-dislocation group (68%) and 35 patients in the dislocation group (32%). Patient demographics and co-morbidities were similar between the two groups. The incidence of open fractures and the application of an external fixator were significantly higher in the dislocation group (p = 0.037 and p = 0.003, respectively). The dislocation group showed a significant decrease in the accuracy of articular reduction (p = 0.003). At a mean follow-up of 21 months, ankle fracture-dislocation patients had increased pain (p = 0.005) and decreased activities of daily living (p = 0.014) on FAOS outcome measures and significantly worse ankle and subtalar ROM. CONCLUSIONS: The results of this study suggest that concurrent dislocation at time of ankle fracture is associated with worse radiographic and functional outcomes, but not an increase in superficial or deep infection. The results from this study may be helpful in counseling patients regarding expected clinical outcomes after ankle fracture-dislocation and in the surgical management of this complex injury.

Elective removal of implants after open reduction and internal fixation of Tibial Plateau fractures improves clinical outcomes.

INTRODUCTION: Tibial plateau fractures are common injuries often treated with open reduction and internal fixation. We have noted improved patient satisfaction following implant removal for these patients. The purpose of this study was to assess the effect of removal of surgical implants after union on patient reported outcomes. MATERIALS AND METHODS: All patients at our Level 1 Trauma Center undergoing open reduction an internal fixation by the senior surgeon are offered enrollment into a prospective registry and have clinical outcomes recorded at follow-up [Knee Outcomes Survey (KOS), Lower Extremity Functional Scale (LEFS), Short Form-36 Physical and Mental Component Summary (SF-36 PCS, SF-36 MCS), and Visual analog pain scale (VAS)]. Routinely, removal of surgical implants is offered after fracture union resulting in two cohorts: those who had undergone elective removal of surgical implants and those who had not. Outcome scores were compared before and after implant removal as well as between the two study populations at final follow-up. RESULTS: Seventy-five patients were identified as having 12 month outcome scores: 36 (48%) had retained implants; 39 (52%) had implants removed. KOS and LEFS outcomes improved significantly after implant removal (p < 0.05). Clinical outcomes (KOS, SF-36 PCS) were also significantly better in patients who had implants removed compared to those that did not at final follow-up (p < 0.05). There was no statistical difference seen in VAS pain scores. CONCLUSIONS: The results of this study indicate that patients who have elective removal of their surgical implants after open reduction and internal fixation of a tibial plateau fracture have improved clinical outcomes after removal and also demonstrate significantly better outcomes than those who have retained implants at final follow-up. Patients who are unhappy with their clinical result should be counseled that removal of the implant may improve function, but may not improve pain.

Manual Stress Ankle Radiography Has Poor Ability to Predict Deep Deltoid Ligament Integrity in a Supination External Rotation Fracture Cohort.

Stress ankle radiographs are routinely performed to determine deep deltoid ligament integrity in supination external rotation (SER) ankle fractures. However, variability is present in the published data regarding what medial clear space (MCS) value constitutes a positive result. The purposes of the present study were to evaluate the diagnostic accuracy of different MCS cutoff values and determine whether this clinical test could accurately discriminate between patients with and without a deep deltoid ligament disruption. MCS measurements were recorded for stress ankle injury radiographs in an SER ankle fracture cohort. Preoperative ankle magnetic resonance imaging studies, obtained for all patients, were then read independently by 2 musculoskeletal attending radiologists to determine deep deltoid ligament integrity. The MCS measurements were compared with the magnetic resonance imaging diagnosis using receiver operating characteristic analyses to determine the sensitivity, specificity, and optimal data-driven cutoff values. SER II-III patients demonstrated a mean stress MCS distance of 4.3 ± 0.98 mm compared with 5.8 ± 1.76 mm in the SER IV cohort (p < .001). An analysis of differing MCS positive cutoff thresholds revealed that a stress MCS of 5.0 mm maximized the combined sensitivity and specificity of the external rotation test: 65.8% sensitive and 76.5% specific. Using the receiver operating characteristic curve analysis of the MCS measurement, the calculated area under the curve was 0.77, indicating inadequate discriminative ability for diagnosing SER pattern fractures with or without a deep deltoid ligament tear. Judicious use of additional diagnostic testing in patients with a stress MCS result between 4.0 mm and 5.5 mm is warranted.

Evaluation of Lauge-Hansen designation of Weber C fractures.

Associations between Weber C ankle fractures and pronation external rotation (PER) injuries of the Lauge-Hansen classification have often been incorrectly correlated. The purpose of the present study was to evaluate the Lauge-Hansen designation of Weber C fractures by establishing the proportion of Weber C fractures that are supination external rotation (SER), supination adduction (SA), pronation abduction (PA), PER, and hyperplantarflexion variant fractures. A clinical database of operative ankle fractures treated by the senior author (D.G.L.) was reviewed. The inclusion criteria were patient age older than 16 years, preoperative ankle radiographs, and Weber C fracture designation. A total of 132 patients met the inclusion criteria, and the proportion of PA, PER, SER, SA, and variant fractures among the Weber C fractures was analyzed. PA fractures accounted for 0.8% (n = 1), PER fractures 56.8% (n = 75), SER fractures 35.6% (n = 47), and hyperplantarflexion variant fractures 6.8% (n = 9) of the 132 Weber C fractures. Patients with Weber C-PER fractures were more commonly male (p = .005) and younger (p = .003) and demonstrated a greater fibular fracture height (p < .001) than those with Weber C-SER and Weber C-variant fractures. Our study quantitatively demonstrated that not all Weber C fractures occur secondary to pronation injuries. This distinction is important, because all pronation injuries will demonstrate medial ankle injury, but SER and variant fractures might not. We therefore recommend careful evaluation of the fibular fracture characteristics, including the direction of fracture propagation and the distance from the tibial plafond, when classifying Weber C fractures using the Lauge-Hansen system, because correct classification is vital in preparation for appropriate operative treatment.

Complications following treatment of supination external rotation ankle fractures through the posterolateral approach.

BACKGROUND: The posterolateral approach to the ankle is a valuable approach for the treatment of ankle fractures (SER) ankle fractures. The purpose of this study was to determine the complication rate for ankle fractures treated through the posterolateral approach. We hypothesized that this approach would be associated with a low incidence of complications and good clinical outcomes. METHODS: A total of 112 patients with SER ankle fractures treated through a posterolateral approach met inclusion criteria. Prospectively collected data were examined retrospectively from chart review, preoperative plain radiographs, and MRI as well as postoperative radiographs. The mean age was 51.5 (range, 18 to 86) years. The primary outcome of the study was major (surgical debridement, flap, or split thickness skin graft) and minor (epidermolysis requiring local wound care) wound complications. The secondary outcomes included infection, symptomatic hardware, reoperation, loss of reduction, malreduction, nonunion, Foot and Ankle Outcome Scores, range of motion, and other perioperative complications. RESULTS: There were 11 minor wound related complications (9.8%) and 3 major wound complications (2.7%), 1 of which required a split thickness skin graft. The overall postoperative wound infection rate was 4.4% (5 of 112); 2 patients required hardware removal due to deep infection. Of patients, 7% (8 of 112) reported symptomatic lateral sided hardware and thus underwent removal of implants. The overall reoperation rate was 12.5%. The complication rate was 23%. No patients experienced loss of reduction. CONCLUSIONS: The posterolateral approach to the ankle was a valuable approach for SER ankle fractures. This series demonstrated many key aspects of this approach including access to the apex of the fibula fracture for posterior antiglide plating, access to the posterior malleolus for fixation, access to the posterior inferior tibiofibular ligament for repair, minimal major wound complications, good functional outcomes, and minimal need for reoperation.

Comparison of supination external rotation type IV ankle fractures in geriatric versus nongeriatric populations.

BACKGROUND: Geriatric patients' (defined as those older than 65 years old) inherent comorbidities, functional limitations, and bone quality present obstacles to successful clinical outcomes for operatively treated supination external rotation (SER) ankle fractures. We retrospectively reviewed a prospectively collected series of SER injuries between 2004 and 2010. This is a comparison of the radiographic and clinical outcomes of our geriatric (27 patients) and nongeriatric (81 patients) populations. We hypothesized that geriatric patients would have worse outcomes when compared to nongeriatric patients. METHODS: All SER ankle fractures (176) treated by a single surgeon were enrolled in a prospective database. All patients fulfilled inclusion criteria (108) consisting of 1 year of having clinical follow-up, postoperative radiographs, and Foot & Ankle Outcome Scores (FAOS). The primary outcome evaluated was functional outcome as exhibited by the FAOS. The secondary outcomes included adequacy of reduction, loss of reduction, postoperative complications (wound complications, infection, pain-driven hardware removal), and range of motion. RESULTS: Despite significantly higher rates of diabetes (P < .001) and peripheral vascular disease (P < .001), there were statistically significantly better FAOS outcomes in the symptoms subcategory among the geriatric population. There was no significant difference in the articular reduction, syndesmotic reduction, wound complications, postoperative infections, or range of motion between these groups. CONCLUSION: Geriatric patients exhibited equivalent complication rates, radiographic outcomes, and functional outcomes compared to nongeriatric patients in this series. Anatomic fixation and soft tissue management counter the inherent risks of operative intervention in geriatric populations that report higher rates of comorbidities. This study supports aggressive fracture- and ligament-specific operative intervention in geriatric patients presenting with unstable SER injuries.

Small residual fracture gaps delay time to union in length stable femur fractures treated with intrameduallary fixation.

OBJECTIVES: The purpose of this study was to investigate whether residual fracture gapping and translation at time of intramedullary nail (IMN) fixation for diaphyseal femur fractures were associated with delayed healing or nonunion. DESIGN: Retrospective cohort study SETTING: Level 1 trauma hospital, quaternary referral center PATIENTS/PARTICIPANTS/INTERVENTION: Length stable Winquist type 1 and 2 diaphyseal femur fractures treated with IMN at a single Level I trauma center were retrospectively reviewed. MAIN OUTCOME MEASURE: The largest fracture gap and translation were evaluated on immediate anteroposterior (AP) and lateral postoperative radiographs. Radiographic healing was assessed using Radiographic Union Score in Femur (RUSF) scores at each follow-up. Radiographic union was defined as a RUSF score ≥8 and consolidation of at least 3 cortices. ANOVA and student's t-tests were used to evaluate the influence of fracture gap parameters on time to union (TTU) and nonunion rate. Patients were stratified to measured average gap and translation distances <1mm, 1-3mm and >3mm for portions of the analysis. RESULTS: Sixty-six patients who underwent IMN with adequate follow-up were identified. A total of 93.9% of patients achieved union at an average of 2.8 months. Fractures with average AP/lateral gaps of <1mm, 1-2.9 mm, and >3mm had an average TTU of 70.1, 91.7, and 111.9 days respectively; fractures with larger residual gap sizes had a significantly longer TTU (p=0.009). Fractures with an average gap of 1-2.9mm and >3 mm had a significantly higher nonunion rate (1.5% and 4.5% respectively) compared to 0% nonunion in the <1 mm group (p=0.003). CONCLUSION: Residual gapping following intramedullary fixation of length stable diaphyseal femur fractures is associated with a significant increase in likelihood of nonunion. SUMMARY: Residual displacement of length stable femoral shaft fractures following intramedullary nailing can have a significantly negative impact on fracture healing. An average 3 mm AP/lateral residual fracture gap or a total of 6 mm of the AP + lateral fracture gap appeared to be a critical gap size with increased rates of nonunion and time to union. Therefore, we suggest minimizing the sum of the residual AP and lateral fracture gap to less than a total of 6 mm.

Effect of Computerized Tomography on Assessment and Surgical Planning for Olecranon Fractures.

OBJECTIVES: (1) Determine effects of computed tomography (CT) on reproducibility of olecranon fracture classification. (2) Determine effects of CT utilization on interobserver agreement regarding management of olecranon fractures. (3) Evaluate factors associated with articular impaction. METHODS: Seven surgeons retrospectively evaluated radiographs of 46 olecranon fractures. Each fracture was classified according to Colton, Mayo, Orthopaedic Trauma Association/AO Foundation (OTA/AO) systems. Observers determined whether articular impaction was present and provided treatment plans. This was repeated at minimum 6 weeks with addition of CT. Descriptive and comparative statistics were performed and intraclass correlation coefficients (ICCs) were calculated. RESULTS: Interrater agreement was near-perfect for all classifications using radiographs (ICC 0.91, 0.93, 0.89 for Colton, Mayo, OTA/AO) and did not substantially change with CT (ICC 0.91, 0.91, 0.93). Agreement was moderate regarding articular impaction using radiographs (ICC 0.44); this improved significantly with CT (ICC 0.82). Articular impaction was significantly associated with OTA/AO classification, with high prevalence of impaction in OTA/AO 2U1B1e ( P < 0.03). Agreement was substantial for chosen fixation construct using radiographs (ICC 0.71); this improved with CT (ICC 0.79). Utilization of CT changed fixation plans in 25% of cases. Agreement regarding need for void filler was fair using radiographs (ICC 0.37); this notably improved with CT (ICC 0.64). CONCLUSIONS: Utilization of CT for evaluating olecranon fractures led to significant improvements in interobserver agreement for presence of articular impaction. Impaction was significantly associated with fracture pattern, but not with patient-related factors. Addition of CT improved agreement regarding fixation construct and led to notable improvement in agreement regarding need for void filler.

Medialized Trochanteric Entry Nailing Is a Safe and Effective Method for High-Energy Subtrochanteric Femur Fracture Treatment.

Fixation of subtrochanteric femur fractures using intramedullary nails can provide high rates of osseous union. However, a lateral starting point or a medial trajectory can result in varus alignment, typically seen with trochanteric entry nails. Even with piriformis nails, medial comminution can result in secondary malalignment and varus. Varus can predictably result in nonunion and need for repeat operations. Medialized trochanteric entry nailing has been reported previously as a method to prevent varus alignment in low-energy, atypical subtrochanteric femur fractures in association with bisphosphonate use. We present a surgical technique using a medialized trochanteric nail entry point to provide proper alignment and avoidance of varus malreduction in 24 patients with a subtrochanteric femur fracture after a high-energy traumatic event.

In-Hospital Morbidity and Mortality With Delays in Femoral Shaft Fracture Fixation.

OBJECTIVES: To investigate trends in the timing of femur fracture fixation in trauma centers in the United States, identify predictors for delayed treatment, and analyze the association of timing of fixation with in-hospital morbidity and mortality using data from the National Trauma Data Bank. METHODS: Patients with femoral shaft fractures treated from 2007 to 2015 were identified from the National Trauma Data Bank and grouped by timing of femur fixation: <24, 24-48 hours, and >48 hours after hospital presentation. The primary outcome measure was in-hospital postoperative mortality rate. Secondary outcomes included complication rates, hospital length of stay (LOS), days spent in the intensive care unit LOS (ICU LOS), and days on a ventilator. RESULTS: Among the 108,825 unilateral femoral shaft fractures identified, 74.2% was fixed within 24 hours, 16.5% between 24 and 48 hours, and 9.4% >48 hours. The mortality rate was 1.6% overall for the group. When fixation was delayed >48 hours, patients were at risk of significantly higher mortality rate [odds ratio (OR) 3.60; 95% confidence interval (CI), 3.13-4.14], longer LOS (OR 2.14; CI 2.06-2.22), longer intensive care unit LOS (OR 3.92; CI 3.66-4.20), more days on a ventilator (OR 5.38; CI 4.89-5.91), and more postoperative complications (OR 2.05; CI 1.94-2.17; P < 0.0001). CONCLUSIONS: Our study confirms that delayed fixation of femoral shaft fractures is associated with increased patient morbidity and mortality. Patients who underwent fixation >48 hours after presentation were at the greatest risk of increased morbidity and mortality. Although some patients require optimization/resuscitation before fracture fixation, efforts should be made to expedite operative fixation. LEVEL OF EVIDENCE: Prognostic Level III.

A Comparison of the Prevalence of, Demographics of, and Effects on Outcomes of Bilateral Versus Unilateral Femoral Shaft Fractures: A Retrospective Cohort Analysis From the National Trauma Data Bank.

OBJECTIVES: To document the prevalence of, and the effect on outcomes, operatively treated bilateral femur fractures treated using contemporary treatments. DESIGN: A retrospective cohort using data from the National Trauma Data Bank. PARTICIPANTS: In total, 119,213 patients in the National Trauma Data Bank between the years 2007 and 2015 who had operatively treated femoral shaft fractures. MAIN OUTCOME MEASUREMENTS: Complication rates, hospital length of stay (LOS), days in the intensive care unit (ICU LOS), days on a ventilator, and mortality rates. RESULTS: Patients with bilateral femur fractures had increased overall complications (0.74 vs. 0.50, P < 0.0001), a longer LOS (14.3 vs. 9.2, P < 0.0001), an increased ICU LOS (5.3 vs. 2.4, P < 0.0001), and more days on a ventilator (3.1 vs. 1.3, P < 0.0001), when compared with unilateral fractures. Bilateral femoral shaft fractures were independently associated with worse outcomes in all primary domains when adjusted by Injury Severity Score (P < 0.0001), apart from mortality rates. Age-adjusted bilateral injuries were independently associated with worse outcomes in all primary domains (P < 0.0001) except for the overall complication rate. A delay in fracture fixation beyond 24 hours was associated with increased mortality (P < 0.0001) and worse outcomes for all other primary measures (P < 0.0001 to P = 0.0278) for all patients. CONCLUSIONS: Bilateral femoral shaft fractures are an independent marker for increased hospital and ICU LOS, number of days on a ventilator, and increased complication rates, when compared with unilateral injuries and adjusted for age and Injury Severity Score. Timely definitive fixation, in a physiologically appropriate patient, is critical because a delay is associated with worse inpatient outcome measures and higher mortality rates.

Proximal Tibia Skeletal Traction: Technique and Indications.

SUMMARY: Skeletal traction is a fundamental tool for the orthopaedic surgeon caring for patients with traumatic pelvic and lower-extremity orthopaedic injuries. Skeletal traction has proven to be an effective initial means of stabilization in patients with these injuries. Traction may be used for both temporary and definitive treatment in a variety of orthopaedic injuries. With the appropriate knowledge of regional anatomy, skeletal traction pins can be placed safely and with a low rate of complications. Several methods for placing skeletal traction have been described, and it is critical for orthopaedic surgeons to be proficient not only in their application but also understanding of the appropriate indications for use. Here we present a case example of a patient with a right femur fracture and discuss the technique and indications for placement of proximal tibia skeletal traction.

Surgical Wound Complications After Percutaneous Posterior Pelvic Ring Fixation in Patients Who Undergo Pelvic Arterial Embolization.

OBJECTIVE: To report on the incidence of surgical wound complications after percutaneous posterior pelvic ring fixation in patients who have also undergone pelvic arterial embolization (PAE) and determine whether the risks outweigh the benefits. DESIGN: Retrospective cohort study. SETTING: Academic level 1 trauma center. PATIENTS: Two hundred one consecutive patients who underwent percutaneous posterior pelvic fixation at our institution were included in this study. Of these, 27 patients underwent pelvic arterial embolization. INTERVENTION: Percutaneous posterior pelvic fixation and pelvic arterial embolization. MAIN OUTCOME MEASUREMENTS: Charts were reviewed for posterior percutaneous surgical wound complications including infection, dehiscence, seroma, tissue necrosis, and return to OR for debridement in all patients. RESULTS: Of the 27 patients who received PAE, none developed posterior surgical wound complications. Of those who did not receive PAE, there was one posterior surgical wound complication documented. There were no cases of wound infection in either group. CONCLUSION: Pelvic arterial embolization can be a valuable intervention in treating hemodynamically unstable patients with pelvic ring injuries. Although even selective pelvic arterial embolization is not entirely benign, there seems to be minimal risk of wound complications when percutaneous posterior pelvic ring fixation is performed. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

This video demonstrates the Kocher-Langenbeck approach to the posterior acetabulum, as well as operative indications, surgical reduction and fixation techniques, and outcomes for posterior wall acetabular fractures.

Morbid obesity is not a risk factor for mortality in critically ill trauma patients.

BACKGROUND: Age, Injury severity score (ISS), hyperglycemia (HGL) at admission, and morbid obesity are known risk factors of poor outcome in trauma patients. Our aim was to which risk factors had the highest risk of death in the critically ill trauma patient. METHODS: A Trauma Registry of the American College of Surgeons database retrospective study was performed at our Level I trauma center from January 2000 to October 2004. Inclusion criteria were age >15 years and >or=3 days hospital stay. Data collected included age, gender, and ISS. Groups were divided into nonobese and morbidly obese (MO) (body mass index, BMI >or=40 kg/m2) and into HGL (mean >or=150 mg/dL on initial hospital day) and non-HGL. Primary outcome was 30-day mortality. Differences in mortality and demographic variables between groups were compared using Fisher's exact and Wilcoxon's rank sum tests. Univariate and multivariate logistic regression was used to assess the relationship of HGL, morbid obesity, age, and injury severity to risk of death. Relationships were assessed using odds ratios (OR) and area under the receiver operator characteristic curve (AUC). RESULTS: A total of 1,334 patients met study criteria and 70.5% were male. Demographic means were age 40.3, ISS 25.7, length of stay 13.4, and BMI 27.5. The most common mechanism of injury was motor vehicle collision 55.1%. Overall mortality was 4.7%. Mortality was higher in HGL versus non-HGL (8.7% vs. 3.5%; p < 0.001). Mortality was higher in MO versus nonobese, but not significantly (7.8 vs. 4.6%; not significant [NS] p = 0.222). Univariate logistic regression relationships of death to age OR: 1.031, p < 0.001, AUC +/- SE: 0.639 +/- 0.042; ISS OR: 1.044, p < 0.001, AUC +/- SE: 0.649 +/- 0.039; HGL OR: 2.765, p < 0.001; MO: OR: NS, p = NS, AUC +/- SE: NS. Relationships were similar in a combined multivariate model. CONCLUSION: HGL >150 mg/dL on the day of admission is associated with twofold increase in mortality, and an outcome measure should be followed. Morbid obesity (BMI >or=40) is not an independent risk factor for mortality in the critically ill trauma patient.

Ninety-Five Degree Angled Blade Plate Fixation of High-Energy Unstable Proximal Femur Fractures Results in High Rates of Union and Minimal Complications.

OBJECTIVES: To describe the surgical technique and clinical outcomes of high-energy proximal femur fractures treated with a 95-degree angled blade plate. DESIGN: Retrospective case series. SETTING: Single academic Level I trauma center. PATIENT/PARTICIPANTS: Forty-five consecutive patients from March 2012 to April 2017 who sustained a high-energy, unstable proximal femur fracture including (OTA/AO 31-A1, 31-A2, 31-A3, 31-B3, 32-A1a, and 32-C3i). INTERVENTION: Open reduction internal fixation with a 95-degree angled blade plate used in conjunction with an articulated tensioning device. MAIN OUTCOME MEASUREMENTS: Nonunion, malunion, secondary operations, and postoperative infection. RESULTS: Twenty six patients were available for follow-up. The mean age was 43.8 (range 22-86) years, and 81% (21/26) were men. The most common fracture pattern was OTA/AO 31-A3.3. Two fractures were open. The articulated tensioner was used in 100% of cases. Average clinical follow-up was 19.2 (range 7-40) months. Twenty-four of 26 patients (92%) achieved osseous union after the index procedure. One patient underwent nonunion repair, and 2 patients had the blade plate removed as it was symptomatic laterally. No other secondary procedures were performed, and no instances of implant failure were seen. No patients had evidence of a superficial or deep infection. CONCLUSIONS: We found that high-energy proximal femur fractures treated with a 95-degree condylar blade plate and articulated tensioning device had a high rate of union with minimal postoperative complications. Although intramedullary nailing of these fractures remains a preferred treatment modality, the angled blade plate with articulated tensioning device is an excellent option to restore anatomical alignment and obtain bony union in certain highly comminuted fracture patterns. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Medialized Trochanteric Starting Point and Focused Lateral Endosteal Beak Reaming to Optimize Success of Intramedullary Nailing in Atypical Femur Fractures: A Technical Trick and Case Series.

Optimal intramedullary treatment of atypical femur fractures associated with bisphosphonate use requires avoidance of postoperative malreduction, particularly varus. This can be difficult to achieve, given the fracture location, errors with nail entry point, endosteal beaking, and underlying patient osteology, all of which can contribute to postoperative varus and predispose the patient to treatment failure. We present a surgical technique and clinical series of 10 patients emphasizing a medialized trochanteric nail entry point and preferential lateral endosteal reaming to secure a biologically and biomechanically favorable reduction and fixation.

Outcomes of Proximal Humerus Fracture Open Reduction Internal Fixation with Concomitant Ipsilateral Shoulder Girdle Injuries: a Case Control Study.

BACKGROUND: Proximal humerus fractures treated in the face of ipsilateral injuries to the shoulder girdle may be predisposed to worse clinical outcomes. QUESTIONS/PURPOSES: The purpose of this investigation was to examine outcomes of proximal humerus fractures treated with open reduction internal fixation (ORIF) using an endosteal augment in the presence of a concomitant shoulder girdle injury in comparison to isolated proximal humerus fractures treated with ORIF and endosteal augment. METHODS: A prospective database was used to identify proximal humerus fractures with ipsilateral shoulder girdle injuries (glenohumeral and acromioclavicular dislocation, fractures of the acromion, clavicle, scapula, or humeral diaphysis). These were compared to isolated proximal humerus fractures treated in the same fashion (ORIF with endosteal augment). Minimum of 1 year follow-up was required for inclusion. Outcomes assessed included range of motion (ROM), development of avascular necrosis (AVN), hardware-related complications, reoperation, and subjective outcome assessments including the Disabilities of Arm Shoulder and Hand questionnaire (DASH), Constant score, UCLA rating scale, and the Short Form-36 (SF-36). RESULTS: Fifteen ipsilateral injuries were seen in 14 patients. Seventy-seven isolated proximal humerus fractures were available for comparison. The ipsilateral injury group had significantly worse forward flexion (141 vs 156°, p = 0.02), external rotation (56 vs 64°, p = 0.03), higher rates of avascular necrosis (4 of 14, 28.6% vs 1 of 77, 1.3%, p = 0.002), and inferior SF-36 physical health scores (48.5 vs 63.5; p = .04). Despite these differences, no significant differences were seen with hardware-related complications or DASH, Constant score, or UCLA rating scale results. No patients required secondary reconstructive procedures. CONCLUSION: Despite a statistically higher rate of AVN and decreased ROM, patient-based outcomes of proximal humerus fractures with ipsilateral shoulder injuries approached those seen in isolated proximal humerus fractures. This suggests that these injuries can achieve similarly good clinical results provided any associated shoulder pathology is identified and treated appropriately.
