RESUMO

PURPOSE: To determine if subchondral rafting wires retained as adjunctive tibial plateau fracture fixation affect postoperative articular subsidence. METHODS: A retrospective cohort study was conducted at one Level 1 trauma center and one academic university hospital. Consecutive adults with closed, displaced OTA/AO 41B/C tibial plateau fractures treated between 2018 and 2023 with open reduction internal fixation were included. Patients who were not ambulatory, with contralateral injuries limiting weight bearing, and without follow-up radiographs of the injured extremity were excluded. The intervention was retention of subchondral rafting wires as definitive fixation. The primary outcome was linear articular surface subsidence between postoperative and follow-up AP knee radiographs. Linear subsidence was compared between groups using Welch's two sample t test. Associations of linear subsidence with patient, injury, and treatment characteristics were assessed by multivariable linear regression. RESULTS: We identified 179 patients of a mean age of 44 ± 14 years, of whom 15 (8.4%) received subchondral rafting wires. Median follow-up was 121 days. No patients who received rafting wires as definitive implants experienced linear subsidence ≥ 2 mm, while 22 patients (13.4%) who did not receive rafting wires experienced linear subsidence ≥ 2 mm (p = 0.130). Subchondral rafting wires were associated with less linear subsidence (0.3 mm [95% confidence interval - 0.3-0.9 mm] vsersus 1.0 mm [- 0.9-2.9 mm], p < 0.001). The depth of linear subsidence was significantly associated on multivariable regression with male sex, depressed plateau area, active smoking, and retained rafting wires. CONCLUSION: Subchondral rafting wires were associated with a small reduction in articular subsidence after internal fixation of tibial plateau fractures. Routine rafting wires may be useful for patients and fractures at high risk of articular subsidence.

RESUMO

PURPOSE: We sought to define how changes in position and rotation of fluoroscopic imaging may affect the assessment of condylar widening intraoperatively. METHODS: Thirty-three patients with tibial plateau fractures were prospectively identified and included in this study. Fluoroscopic images of the uninjured tibial plateau were obtained in (1) full extension and (2) slight flexion on foam ramp. Beginning with a plateau view, additional views of the tibial plateau were then obtained by rotating the fluoroscope around the knee in 5 degree increments up to 15 degrees in both internal and external rotation. Measurements of distal femoral condylar width (DFW), distal femoral articular width (FAW), proximal tibial articular width (TAW) and lateral plateau width (LPW) were performed. RESULTS: LPW was decreased in flexion compared to extension at all degrees of rotation (p = 0.04-0.00001). There was a trend toward increasing LPW with increasing degrees of internal rotation which reached significance at 15˚ of internal rotation when the knee was flexed. On ANOVA, there was a significant difference of LPW with increasing degree of internal rotation when the knee was in flexion (p = 0.008), but not in extension. There were no differences in DFW, FAW, TAW and DFW/TAW at any point though LPW was decreased in flexion at all degrees of rotation. The FAW/TAW ratio was increased in flexion at all degrees of rotation. DISCUSSION: The knee in flexion will underestimate the measurement of condylar width compared to the knee in full extension, by ~ 2 mm. Rotation of the knee, in comparison, did not have a significant effect on condylar width assessment. LEVEL OF EVIDENCE: Diagnostic II.

RESUMO

Malreductions in the axial plane (ie, length and rotation) are common when managing long bone fractures. Careful attention to detail during the initial treatment can prevent these malreductions. Various fluoroscopy-based techniques exist for the prevention of malrotation and limb-length discrepancy during surgery for fracture. If malreductions do occur, a systematic clinical and radiographic evaluation can provide the necessary information to correct rotational malreduction and limb-length discrepancy.

RESUMO

Multiple successful strategies exist for the management of critical-sized bone defects. Depending on the location and etiology of an osseous defect, there are nuances that must be considered by the treating surgeon. The induced membrane technique and various modifications of the Ilizarov method (bone transport by distraction osteogenesis) have been the most common methods for biologic reconstruction. Despite the versatility and high union rates reported, they may not be practical for every patient. The rapid expansion of three-dimensional printing of medical devices has led to an increase in their use within orthopaedic surgery, specifically in the definitive treatment of critical bone defects. This article proposes indications and contraindications for implementation of this technology and reviews the available clinical evidence on the use of custom nonresorbable implants for the treatment of traumatic bone loss. Clinical cases are presented to illustrate the scenarios in which this approach is viable.

RESUMO

PURPOSE: Quality of reduction is of paramount importance after acetabular fracture and is best assessed on computed tomography (CT). A recently proposed measurement technique for assessment of step and gap displacement is reproducible but has not been validated. The purpose of this study is to validate a well-established measurement technique against known displacements and to determine if it can be used with low dose CT. METHODS: Posterior wall acetabular fractures were created in 8 cadaveric hips and fixed at known step and gap displacements. CT was performed at multiple radiation doses for each hip. Four surgeons measured step and gap displacement for each hip at all doses, and the measurements were compared to known values. RESULTS: There were no significant differences in measurements across surgeons, and all measurements were found to have positive agreement. Measurement error < 1.5 mm was present in 58% of gap measurements and 46% of step measurements. Only for step measurements at a dose of 120 kVp did we observe a statistically significant measurement error. There was a significant difference in step measurements made by those with greater and those with fewer years in practice. CONCLUSION: Our study suggests this technique is valid and accurate across all doses. This is important as it may reduce the amount of radiation exposure for patients with acetabular fractures.

RESUMO

We sought to determine the type, frequency, and compensation details of orthopedic call for orthopedic traumatologists. We administered a 24-question survey to all members of the Orthopaedic Trauma Association regarding the number and type of orthopedic surgeons within the call pool, frequency of call, number of hospitals covered, and compensation for weekday, weekend, holiday, and pediatric calls. A total of 105 orthopedic surgeons replied. The most common number of physicians in the call pool was 6 to 10 (42.9%), whereas the most common number of traumatologists was 0 to 5 (90.5%), with 71.4% taking call at 1 hospital. Further, 56.7% were paid separately for weekday trauma call, with the most common number of call days per week being 2. The most common compensation was $1001 to $1500 (31.6%). For weekend call, 49.5% of physicians were paid separately, with the most common number of weekends on call per year being 11 to 15 (34.3% of replies). For pediatric call, 54.3% of physicians took call, with 28.6% paid separately and 33.3% receiving $0 to $500. For holiday call, 40.2% of physicians were paid separately, with 30.8% receiving $1001 to $1500. We describe the characteristics of traumatology call. Approximately 50% of physicians (range, 28.6%-56.3%) are compensated separately for taking different forms of call (ie, weekday, weekend, holiday). [Orthopedics. 2022;45(5):293-296.].

RESUMO

OBJECTIVES: To evaluate a proposed orthopaedic-specific surgical wound classification system (SWCS) and the current Centers for Disease Control (CDC) system in a series of detailed clinical vignettes and to identify the degree of satisfaction with CDC SWCS and desire for institution of an orthopaedic-specific SWCS. METHODS: Forty-five clinical vignettes and a 5-question survey were distributed to current and past members of the Orthopaedic Trauma Association's Classification Committee. Respondents were asked to provide wound class for each vignette using the CDC system and orthopaedic-specific SWCS. RESULTS: The orthopaedic-specific and CDC SWCS had interclass correlations of 0.95 and 0.91, respectively. When the systems were compared, in 34% of cases, there was no grade change; in 63% of cases, the wound was graded higher using the orthopaedic-specific SWCS. When only the procedure was changed between vignettes, wound classification was infrequently affected. There was near universal dissatisfaction with the CDC SWCS and desire for an orthopaedic-specific system. CONCLUSIONS: Both the CDC SWCS and orthopaedic-specific SWCS have excellent interobserver reliability. Incorporation of orthopaedic-specific language affects wound classification. There is low satisfaction with the current CDC SWCS and a desire exists for further development and validation of an orthopaedic-specific SWCS.

RESUMO

PURPOSE: To assess the accuracy of radiographs in detecting the lateral plateau involvement of medial tibial plateau fractures as well as describe the impact of CT on preoperative planning for this specific fracture morphology. METHODS: Radiograph and CT imaging of patients with a Schatzker type IV tibial plateau fractures (AO/OTA 41-B1.2, B1.3 h, B2.2. B3.2, and B3.3) between January 2013 and July 2017 were reviewed by three trauma fellowship-trained orthopedic surgeons to identify fractures of the medial condyle with an intact anterolateral articular surface. RESULTS: Lateral plateau involvement was identified in 16 (37%) radiographs and 26 (61%) CT images (p = 0.051). Radiographic detection of lateral plateau involvement demonstrated a sensitivity of 62% and specificity of 100%, and radiographs were able to predict the recommendation for surgical intervention for lateral plateau involvement with a positive predictive value (PPV) of 75% and a negative predictive value (NPV) of 60% compared to recommendations based on CT imaging. Radiographs predicted a need for a separate surgical approach with PPV of 63% and NPV of 70% when compared to recommendations based on CT images. CONCLUSIONS: Radiographs are reliable in ruling in lateral plateau involvement of medial plateau fractures, but occult lateral articular extension may only be identified in CT imaging for some cases. Surgical planning may be impacted by CT imaging for this fracture morphology, but further study is warranted to evaluate the correlation between preoperative planning and clinical outcomes. LEVEL OF EVIDENCE: III.

RESUMO

PURPOSE: The purpose of this study was to describe the incidence of subsidence in patients with AO/OTA 41 (tibial plateau) fractures which were repaired with a novel fenestrated screw system to used to deliver CaPO4 bone substitute material to fill the subchondral void and support the articular reduction. METHODS: Patients with unicondylar and bicondylar tibial plateau fractures were treated according to the usual technique of two surgeons. After fixation, the Zimmer Biomet N-Force Fixation System®, a fenestrated screw that allows for the injection of bone substitute was placed and used for injection of the proprietary calcium phosphate bone graft substitute into the subchondral void. For all included patients, demographic information, operative data, radiographs, and clinic notes were reviewed. Patients were considered to have articular subsidence if one or more of two observations were made when comparing post-operative to their most recent clinic radiographs: > 2 mm change in the distance between the screw and the lowest point of the tibial plateau, > 2 mm change in the distance between the screw and the most superior aspect of the plate. Data were analyzed to determine if there were any identifiable risk factors for complication, reoperation, or subsidence using logistic regression. Statistical significance was set at p < 0.05. RESULTS: 34 patients were included with an average follow-up of 32.03 ± 22.52 weeks. There were no overall differences between height relative to the medial plateau or the plate. Two patients (5.9%) had articular subsidence. Six patients (15.2%) underwent reoperation, two (6%) for manipulations under anaesthesia due to arthrofibrosis, and four (12%) due to infections. There were 6 (19%) total infections as 2 were superficial and required solely antibiotics. One patient had early failure. CONCLUSION: Use of a novel fenestrated screw system for the delivery of CaPO4 BSM results in articular subsidence and complication rates similar to previously published values and appears to be a viable option for addressing subchondral defects in tibial plateau fractures. LEVEL OF EVIDENCE: IV.

RESUMO

INTRODUCTION: Pelvic ballistic injuries threaten critical gastrointestinal, vascular, and urinary structures. We report the treatment patterns and injury profiles of ballistic pelvic fractures and the association between location of ballistic fractures of the pelvis and visceral injuries. METHODS: A prospectively collected database at an academic level I trauma center was reviewed for clinical and radiographic data on patients who sustained one or more ballistic fractures of the pelvis. Main outcomes compared included: procedures with orthopedic surgery, emergent surgery, concomitant intrapelvic injuries, and mortality. RESULTS: Eighty-six patients were included. Eight patients (9.3%) underwent surgical debridement with orthopedic surgery, no ballistic pelvic fractures required surgical stabilization. The anatomical locations of ballistic pelvic fractures included: 10 (14.7%) anterior ring, 13 (19.1%) posterior ring, 27 (39.7%) anterior column, and 18 (20.9%) posterior column. There was a statistically significant association between anterior ring and rectal injury. The association between anterior ring injury and bladder injury approached significance. CONCLUSIONS: This case series included 86 patients with a ballistic fracture of the pelvis, none requiring pelvic ring surgical stabilization. The unpatterned behavior of these injuries demands a high suspicion for visceral injury, with special attention to the rectum and bladder in the setting of anterior ring involvement. LEVEL OF EVIDENCE: IV.

RESUMO

OBJECTIVE: First, to assess the impact of varying computed tomography (CT) radiation dose on surgeon assessment of postfixation acetabular fracture reduction and malpositioned implants. Second, to quantify the accuracy of CT assessments compared with the experimentally set displacement in cadaver specimens. We hypothesized that a CT dose would not affect the assessments and that CT assessments would show a high concordance with known displacement. METHODS: We created posterior wall acetabular fractures in 8 fresh-frozen cadaver hips and reduced them with varying combinations of step and gap displacement. The insertion of an intra-articular screw was randomized. Each specimen had a CT with standard (120 kV), intermediate (100 kV), and low-dose (80 kV) protocols, with and without metal artifact reduction postprocessing. Reviewers quantified gap and step displacement, overall reduction, quality of the scan, and identified intra-articular implants. RESULTS: There were no significant differences between the CT dose protocols for assessment of gap, step, overall displacement, or the presence of intra-articular screws. Reviewers correctly categorized displacement as anatomic (0-1 mm), imperfect (2-3 mm), or poor (>3 mm) in 27.5%-57.5% of specimens. When the anatomic and imperfect categories were condensed into a single category, these scores improved to 52.5%-82.5%. Intra-articular screws were correctly identified in 56.3% of cases. Interobserver reliability was poor or moderate for all items. Reviewers rated the quality of most scans as "sufficient" (60.0%-72.5%); reviewers more frequently rated the low-dose CT as "inferior" (30.0%) and the standard dose CT as "excellent" (25%). CONCLUSION: A CT dose did not affect assessment of displacement, intra-articular screw penetration, or subjective rating of scan quality in the setting of a fixed posterior wall fracture.

RESUMO

INTRODUCTION: Few studies have evaluated the effect of prior bariatric surgery on outcomes following the operative treatment of hip fractures. The purpose of this study is to evaluate these metrics in a population of bariatric surgery patients compared to a control group who were operatively treated for hip fractures. MATERIALS AND METHODS: The California Office of Statewide Health Planning & Development (OSHPD) discharge database was accessed to identify patients who sustained a hip fracture between 2000-2014. CPT codes were utilized to identify patients who had a prior history of bariatric surgery within this time period. A control cohort of patients who had undergone previous appendectomy were queried similarly. The study evaluated complication rates and inpatient mortality at 30- and 90-days postoperatively as well as 30- and 90-day readmission rates. RESULTS: There were 1,327 bariatric and 2,127 control patients identified. Survival rates were significantly lower in bariatric patients compared to controls (87.2% vs. 91.8%, p = 0.048) at 5 years. After controlling for confounders, bariatric patients had higher 30- (OR 1.46, p = 0.005) and 90-day (OR 1.38, p = 0.011) readmission rates. There were no differences in all-cause complication and inpatient mortality rates between groups at 30 or 90 days. DISCUSSION: Bariatric surgery patients are at increased risk of readmission after hip fracture surgery. Further research is warranted to delineate potential risk factors and mitigate readmission in these patients. LEVEL OF EVIDENCE: III.

RESUMO

Bone defects may occur after trauma, infection, or oncologic resection. A critical sized defect is any defect that is unable to spontaneously heal and will require secondary procedure(s) to obtain union. Autologous grafting is widely used, but may be insufficient to obtain union in these situations. Other options include the induced membrane technique, bone transport through distraction osteogenesis, or free vascularized bone transfer. This chapter will review options for obtaining graft, and the aforementioned special techniques for managing these challenging problems.

RESUMO

Marijuana use among orthopedic patients has not been extensively studied. The purpose of this study was to investigate the prevalence of marijuana use among orthopedic surgery patients. Additionally, the authors sought to better characterize how and why their patients use marijuana. Patients presenting at 3 institutions in 2 states for orthopedic surgery were asked to complete a voluntary survey. In addition to basic demographic information, the survey contained questions regarding the frequency of, methods of, and reasons for marijuana use. Patients who had used marijuana in the past year were categorized as marijuana users. A total of 275 patients completed surveys, of whom 94 (34%) endorsed marijuana use in the past year. A majority of marijuana users (55%) endorsed using marijuana either daily or weekly. Smoking was the most common means of marijuana use (90%), followed by edible products (35%) and vaporizing (24%). Pain management (54%) and recreation (52%) were the most commonly cited reasons for using marijuana. Eighty-six percent of marijuana users indicated that they would stop using marijuana if told by their physician that marijuana use would adversely affect their surgery. Marijuana use is common among orthopedic patients. Many patients believe marijuana is beneficial for managing pain and other medical conditions, although most would be willing to stop using marijuana if told it would negatively impact their surgery. Further study into the effects of marijuana use on musculoskeletal health is warranted because marijuana use may be a risk factor easily modified to improve surgical outcomes.

RESUMO

OBJECTIVES: To evaluate the effect of pre-existing mental health (MH) conditions on 90-day complication, 90-day readmission, and all-time revision surgical intervention rates following femoral, tibial, and pilon fractures. DESIGN: Data were collected using a commercially available database software for which Current Procedural Terminology codes were used to identify patients who underwent surgical treatment of tibial, femoral, or pilon fractures. These patients were then subdivided into those with and without pre-existing MH condition using International Classification of Disease, Ninth Edition codes. Ninety-day postoperative complications, revision surgery, and 90-day readmission rates were then compared between those with and without MH conditions. SETTING: National databases of 70 million combined patients from 2007 to 2015. PATIENTS/PARTICIPANTS: Humana and Medicare insured patients. INTERVENTION: Surgical treatment of tibial, femoral, and pilon fractures. MAIN OUTCOME MEASUREMENTS: Ninety-day readmission, 90-day complications, and all-time revision surgical intervention. RESULTS: The total number of patients for femoral, tibial, and pilon treatment, respectively, included 6207, 6253, and 5940 without MH conditions and 4879, 5247, and 2911 with MH conditions. Femoral, tibial, and pilon readmission rates, revision rates, and complication rates were significantly higher among patients with MH disorders in matched cohorts after controlling for medical comorbidities (P ≤ 0.05 for all). CONCLUSIONS: Comorbid MH conditions are associated with higher postoperative complication, readmission, and revision surgery rates for treated femoral, tibial, and pilon fractures. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

RESUMO

Upper extremity gunshot wounds result in notable morbidity for the orthopaedic trauma patient. Critical neurovascular structures are particularly at risk. The fractures are often comminuted and may be associated with a variable degree of soft-tissue injury. The literature lacks consensus regarding antibiotic selection and duration, and indications for surgical débridement. Bullets and/or bullet fragments should be removed in cases of plumbism, intra-articular location, nerve impingement, location within a vessel, and location in a subcutaneous position within the hand and/or wrist. Gunshot fractures generally do not follow common fracture patterns seen in blunt injuries, and the complexity of certain gunshot fractures can often be a challenge for the treating orthopaedic surgeon. Common plate and screw constructs may not adequately stabilize these injuries, and innovative fixation techniques may be required. The treatment for bone defects varies by location and severity of injury, and typically requires staged treatment. Nerve injuries after gunshot wounds are common, but spontaneous nerve recovery is expected in most cases.

RESUMO

OBJECTIVES: We hypothesized that a constant radiographic relationship exists between the lateral tibial and femoral condyles and that no side-to-side variation exists. METHODS: We reviewed anteroposterior x-rays of 217 uninjured adults ages 18-65, Included 109 unilateral and 108 bilateral radiographs with no or minimal osteoarthrosis (Kellgren-Lawrence grades 0-1). The perpendicular distance between the lateral-most margins of the tibial plateau articular surface (A) and the lateral femoral epicondyle (B) and the lateral femoral condyle articular surface (C) was measured in millimeters (mm). Medial and lateral measurements to point (A) were recorded as (-) and (+), respectively. First, the average of measured distances in all unilateral knees and randomly selected either right or left knees from the bilateral group (n = 217) was calculated. Comparison was made between both sexes. Next, A-B and A-C distances were compared between right and left knees in the bilateral group (n = 108) to find any significant difference (2-tailed t test, alpha = 0.05). RESULTS: The average A-B distance was 0.60 ± 2.40 mm (-4.82 to +6.49 mm). The mean A-C distance was -3.96 ± 2.07 mm (-8.51 to +3.98 mm). No significant difference was found between A-B and A-C distances between males (0.40 ± 2.62 mm and -3.91 ± 2.05 mm) and females (0.70 ± 2.28 mm and -3.99 ± 2.09 mm). Similarly, no significant difference was found between A-B and A-C distances between right (1.08 ± 2.31 mm and -3.90 ± 1.73 mm) and left knees (0.90 ± 2.38 mm and -4.31 ± 1.7 mm). Concordance coefficient for interobserver and intraobserver reliability showed substantial agreement. CONCLUSION: In conclusion, this study provided a "normal" range for the relationship of the proximal lateral tibial plateau relative to the lateral femoral condyle. The lateral femoral epicondyle is generally aligned with the lateral tibial articular margin. The relationship between the lateral tibial plateau, lateral femoral epicondylar surface, and lateral femoral articular surface is constant from side to side. This technique is reproducible in the setting of fracture, and templating off of the contralateral uninjured knee may be beneficial in tibial plateau fracture surgery.

RESUMO

INTRODUCTION: Motor Vehicle Collisions (MVC) can cause high energy hip dislocations associated with serious injury profiles impacting triage. Changes in safety and regulation of restraint devices have likely lowered serious injuries from what was previously reported in the 1990s. This study aims to describe modern-day injury profile of patients with traumatic hip dislocations, with special attention to aortic injury. METHODS: Retrospective review of a prospectively maintained trauma database at an urban level 1 trauma center was conducted. Patients with hip dislocation following MVC between January 2005 and December 2015 were grouped based on seatbelt use and airbag deployment. Patients with unknown restraint use were excluded. Multiple logistic regression was used to identify risk of injury profile between groups. RESULTS: Of 204 patients with hip dislocation after MVC, nearly 57% were unrestrained. Seatbelt alone was used in 36 (17.7%), airbag deployed in 14 (6.9%), and 38 (18.6%) with both. Gender and number of injuries were similar between groups. The most common concomitant injury was acetabular fracture (53.92%) and the abdominopelvic region was the most injured. Use of a seatbelt with airbag deployment was protective of concomitant pelvic ring injury (OR = 0.22). Airbag deployment was significantly protective of lumbar fracture (OR = 0.15) while increasing the likelihood of radial and ulnar fracture or dislocation (OR = 3.27), acetabular fracture (OR = 5.19), and abdominopelvic injury (OR = 5.07). The no restraint group had one patient (0.80%) with an intimal tear of the thoracic aorta identified on CT chest that was successfully medically managed. DISCUSSION AND CONCLUSION: Hip dislocations are high energy injuries with severe associated injuries despite upgrades in restraint devices. These patients require careful examination and heightened awareness when evaluating for concomitant injuries.

RESUMO

Talus fractures are relatively uncommon; however, the sequelae of talus fractures can cause significant morbidity. Although avascular necrosis has been a consistently reported complication, the reported rates of subsequent arthrodesis have varied widely. The purpose of the present study was to report the complications in a large patient sample of operatively treated talus fractures and to describe the survivorship of open reduction internal fixation (ORIF) of the talus. Patients undergoing talus ORIF for closed or open fractures from 2007 to 2011 were identified in the United Healthcare System database by International Classification of Diseases, 9th revision, code 825.21 and Current Procedural Terminology codes 28445, 28436, and 28430. Patients with a nonoperative talus fracture or isolated osteochondral defect were excluded, leaving 1527 patients in the final analysis. We also identified patients who had required subsequent subtalar, pantalar, and tibiotalocalcaneal arthrodeses using Current Procedural Terminology codes 28725, 28705, and 28715, respectively. Complications and demographic data were recorded. Of the 1527 patients, 29 (1.9%) had undergone subsequent arthrodesis within 4 years; 64 patients (4.2%) developed wound complications that did not require surgical intervention, 11 patients (0.7%) were readmitted, 204 (13.3%) presented to the emergency department (ED), and 96 (6.3%) underwent operative irrigation and debridement (I&D). The overall complication rate was 19.5%. Patients aged >34 years had a significantly greater rate of ED visits (54.7%, p = .015) and overall complications (56.8%, p < .001). In conclusion, ORIF of talus fractures has good survivorship when considering the failure of initial surgery or the requirement for secondary arthrodesis. Medical complications and hospital readmission were relatively rare; however, ED visits and infection requiring I&D were relatively common after ORIF of talus fractures.
