The Scapular Skiver Screw: A Useful Fixation Technique for Inferior Glenoid and Scapular Neck Fractures.

SUMMARY: The inferior glenoid and scapular neck are common locations for scapular fractures. Operative exposures for reduction and fixation can be challenging, and frequently, the proximal fracture planes are not conducive to optimal fixation with a plate alone. The purpose of this article was to describe a new technique for enhancing fixation in specific inferior glenoid fractures using a single cortical lag screw.

Does Transparency of Ankle Implant Costs Influence Surgeon Behavior?

Background: Ankle fractures are a common injury treated by orthopaedic surgeons. Unstable, displaced ankle fractures are often fixed with open reduction internal fixation (ORIF) using different implant constructs at various cost. No study to date has looked at transparency in ankle implant costs to surgeon behavior. Our surgeons self-identified that the biggest barrier for lowering implant cost was the lack of cost transparency. This was a surgeon-led-study to evaluate whether increased transparency in implant costs affected surgeon behavior. Methods: Monthly operative logs from December 2021 to September 2022 were reviewed at our level 1 trauma center for operative fixation of ankle fractures. The cost data of each fixation construct was reported to trauma-trained surgeons at the end of each month from March 2022 to June 2022. Average costs of implants were compared before and after education. A linear mixed model was used to explore what factors were associated with changes in costs. Surgeons also participated in a poststudy survey. Results: The implant costs of 110 ankle fracture fixations were reviewed over the period before education (n = 60), during education (n = 30), and after education (n = 20). The mean implant cost difference for unimalleolar fractures was -$204.80 (P = .68), whereas the mean cost difference for bimalleolar fractures was -$9.82 (P = .98). Trimalleolar fractures had a mean cost difference of +$94.47 (P = .84). Linear mixed model demonstrated fracture pattern as the only factor significantly associated with implant costs (P < .01). Post-education surgeon survey revealed that 6 of 7 surgeons felt that monthly updates affected their implant selection. However, only 2 surgeons demonstrated a change in practice with decreased implant costs during the study. Conclusion: The majority of surgeons self-reported being influenced by the implant cost education, but the detected change in implant cost was only observed in less than one-third of surgeons. Our results suggest implant selection and related costs are not influenced by increased cost transparency education alone. Level of Evidence: Level III, case control study.

The True-Blue technique: Enhanced chondral assessment of the chest wall.

There is a growing understanding and identification of costal cartilage injuries, however, diagnosis of these injuries remains difficult. We present a novel radiodensity based coloring technique, termed the True-Blue technique, to manipulate 3D CT imaging and more accurately diagnose costochondral injuries.

Three-Dimensional Mapping of Scapular Body, Neck, and Glenoid Fractures.

OBJECTIVES: The purpose of this study was to report patterns of scapular fractures and define them with a contemporary methodology. METHODS: . DESIGN: Retrospective study, 2015-2021. SETTING: Single, academic, Level 1 trauma center. PATIENT SELECTION CRITERIA: Consecutive patients ≥18 years, presenting with unilateral scapula fracture, with thin-slice (≤0.5-mm) bilateral computed tomography (CT) scans of the entirety of both the injured and uninjured scapulae. OUTCOME MEASURES AND COMPARISONS: Thin-slice (0.5-mm) CT scans of injured and normal scapulae were obtained to create three-dimensional (3D) virtual models. 3D modeling software (Stryker Orthopedics Modeling and Analytics, Stryker Trauma GmbH, Kiel, Germany aka SOMA) was used to create a 3D map of fracture location and frequency. Fracture zones were delineated using anatomic landmarks to characterize fracture patterns. RESULTS: Eighty-seven patients were identified with 75 (86%) extra-articular and 12 (14%) intra-articular fractures. The dominant fracture pattern emanated from the superior lateral border (zone E) to an area inferior to the spinomedial angle (zone B) and was present in 80% of extra-articular fractures. A second-most common fracture line propagated from the primary (most-common) line toward the inferior medial scapular border with a frequency of 36%. Bare zones (with 1 or no fractures present) were identified in 4 unique areas. Furthermore, intra-articular fractures were found to be heterogenous. CONCLUSIONS: The 3D fracture map created in this study confirmed that extra-articular scapular fractures occur in certain patterns with a relatively high frequency. Results provide greater insight into scapular fracture locations and may help to study prognosis of injury and improve treatment strategy including operative approaches and surgical tactics.

Chest Wall Injury Society recommendation for surgical stabilization of nonunited rib fractures to decrease pain, reduce opiate use, and improve patient reported outcomes in patients with rib fracture nonunion after trauma.

BACKGROUND: Rib fractures are common injuries which can be associated with acute pain and chronic disability. While most rib fractures ultimately go on to achieve bony union, a subset of patients may go on to develop non-union. Management of these nonunited rib fractures can be challenging and variability in management exists. METHODS: The Chest Wall Injury Society's Publication Committee convened to develop recommendations for use of surgical stabilization of nonunited rib fractures (SSNURF) to treat traumatic rib fracture nonunions. PubMed, Embase, and the Cochrane database were searched for pertinent studies. Using a process of iterative consensus, all committee members voted to accept or reject the recommendation. RESULTS: No identified studies compared SSNURF to alternative therapy and the overall quality of the body of evidence was rated as low. Risk of bias was identified in all studies. Despite these limitations, there is lower-quality evidence suggesting that SSNURF may be beneficial for decreasing pain, reducing opiate use, and improving patient reported outcomes among patients with symptomatic rib nonunion. However, these benefits should be balanced against risk of symptomatic hardware failure and infection. CONCLUSION: This guideline document summarizes the current CWIS recommendations regarding use of SSNURF for management of rib nonunion. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Humerus fractures: selecting fixation for a successful outcome.

Current evidence suggests at least one-third of humeral shaft fractures initially managed nonoperatively will fail closed treatment, and this review highlights surgical considerations in those circumstances. Although operative indications are well-defined, certain fracture patterns and patient cohorts are at greater risk of failure. When operative intervention is necessary, internal fixation through an anterolateral approach is a safe and sensible alternative. Determining which patients will benefit most involves shared decision-making and careful patient selection. The fracture characteristics, bone quality, and adequacy of the reduction need to be carefully evaluated for the specific operative risks for individuals with certain comorbid conditions, inevitably balancing the patient's expectations and demands against the probability of infection, nerve injury, or nonunion. As our understanding of the etiology and risk of nonunion and symptomatic malunion of the humeral diaphysis matures, adhering to the principles of diagnosis and treatment becomes increasingly important. In the event of nonunion, respect for the various contributing biological and mechanical factors enhances the likelihood that all aspects will be addressed successfully through a comprehensive solution. This review further explores specific strategies to definitively restore function of the upper extremity with the ultimate objective of an uninfected, stable union.

Open Reduction and Internal Fixation of a Chronic Precordial Flail Chest Segment: A Case Report.

CASE: We report on a 35-year-old man presenting with disabling pain secondary to multiple rib nonunions and a costochondral dislocation 5 months after sustaining a chest wall crush injury. He underwent surgical reconstruction of the chest and was followed for 2 years. Surgical exposure to the heart was necessary during open reduction of the flail segment, followed by costochondral joint fixation with plates and screws. Although he was a workers' compensation patient, he returned to full gainful employment. CONCLUSION: Open reduction and internal fixation of a symptomatic, chronically displaced, precordial, flail segment can relieve pain and promote return to baseline function.

Surgical management of traumatic sternal body nonunions: Technical tricks and clinical experience.

BACKGROUND: Rarely, traumatic sternum fractures may result in nonunion, which can have drastic, negative implications. Literature on traumatic sternal nonunion reconstruction outcomes is limited to case reports. We present the surgical principles and report clinical outcomes for seven patients following surgical reconstruction of a traumatic sternal body nonunion. METHODS: Consecutive adult patients with a nonunion after a traumatic sternum fracture who underwent reconstruction using locking plate technology and iliac crest bone graft at a Level I trauma center from 2013 to 2021 were identified. Demographic, injury, and surgery data was collected, and postoperative patient-reported outcome (PRO) scores were obtained. Patient-reported outcome scores included the one-question single assessment numeric evaluation (SANE), and the combined 10-question global physical health and global mental health values. Injuries were classified and all fractures were mapped onto a sternum template. Postoperative radiographs were reviewed for union. RESULTS: Of the study's seven patients, five were female, and the mean age was 58 years. Mechanism of injury included motor vehicle collision (5) and blunt object chest trauma (2). The mean time from initial fracture to nonunion fixation was 9 months. Four of the seven patients achieved in-clinic follow-up at ≥12 months (mean = 14.3 months), while the other three achieved ≥6 months of in-clinic follow-up. Six patients completed outcomes surveys ≥12 months after surgery (mean = 28.9 months). Mean PRO scores at final follow-up included: SANE of 75 (out of 100), and global physical health and global mental health of 44 and 47, respectively (US population mean = 50).Six of seven patients achieved known radiographic union. CONCLUSION: We describe an effective and practical method of achieving stable fixation in traumatic sternal body nonunions as evidenced by the positive clinical outcomes of a seven-patient series. Despite the variation in presentation and fracture morphology of this rare injury, the surgical technique and principles outlined can serve as a useful tool for chest wall surgeons.

Effectiveness of an Orthopaedic Trauma Research Fellowship to Produce Successfully Matching Residents.

OBJECTIVE: Orthopaedics is becoming increasingly competitive. Approximately 25% of applicants to orthopaedic surgery go unmatched each year. The mean US Medical Licensing Examination step scores and average publication numbers have increased markedly in recent years. Reapplicants have a match rate of <60%. This study describes the results of an orthopaedic trauma research fellowship and its effectiveness in obtaining a successful orthopaedic match. METHODS: A 1 to 2-year research fellowship was established at a level 1 academic trauma center. Prefellowship and fellowship metrics of 11 fellows were recorded, including undergraduate and medical schools; step-1 + step-2 scores; Alpha Omega Alpha appointment; and publication, podium, poster, and chapter accomplishments. RESULTS: The average step-1 score of the fellows was 218 (range, 192 to 252) and 232 (range, 212 to 254) for step-2. Seven of 11 fellows were reapplicants. Prefellowship, the average number of journal publications was 1, one podium, two posters, and zero textbook chapters. During fellowship, the average publications was 5, five podiums, six posters, and 1.5 textbook chapters. Ten of 11 fellows successfully matched into an orthopaedic residency, with six of seven being reapplicants. CONCLUSIONS: Six of 7 reapplying fellows (86%) successfully matched highlighting the effectiveness of this fellowship. Research fellowships should be considered as an excellent choice for applicants who may be less than ideal candidates or reapplicants.

Deltoid-Sparing Modified Judet Approach: Technique and Clinical Series.

SUMMARY: Posterior approaches provide the mainstay for treatment in most of the scapula body and neck fractures, even those associated with many intraarticular variants. Several posterior approach modifications for minimizing soft-tissue damage and limiting muscular detachment, have previously been described in the literature; however, little or no clinical evidence is available specifically applied to the various approaches.In this study, we describe complete sparing of the deltoid muscle origin during the "modified Judet" approach. The modified approach as previously described detaches the deltoid origin. Deltoid sparing allows for satisfactory visualization and fixation of extra-articular scapula fractures and even some intraarticular variants. The purpose of this article was to describe the deltoid-sparing modified Judet approach and report clinical outcomes for 23 patients after surgical treatment.

Mapping of Pelvic Ring Injuries From High-Energy Trauma Using Unfolded CT Image Technology.

OBJECTIVES: High-energy pelvic ring injuries are associated with significant morbidity and mortality, elevating the importance of injury pattern identification. The purpose of this study was to use a novel 3D computed tomography (CT) unfolding process to both evaluate high-energy pelvic ring injures and to produce injury frequency maps based on injury patterns. METHODS: Patients 18-65 years of age presenting to a level 1 trauma center with pelvic ring injuries between 2016 and 2020 were identified. Of the 482 patients reviewed, 355 were excluded primarily due to having a low energy mechanism, inadequate radiographs, or an isolated fracture. Unfolded pelvic CT images were created using syngo.via CT Bone Reading software. Pelvic ring injury frequency maps were created using the unfolded pelvic CT images and a previously described mapping technique. RESULTS: One hundred twenty-seven patients analyzed had a mean age of 32.7 years. The most common mechanisms of injury (MOI) were motor vehicle collision (30.7%) and fall from height (23.6%). The breakdown of pelvic ring injuries included LC1 = 44.1%, LC2 = 7.1%, LC3 = 14.2%, APC1 = 2.4%, APC2 = 15.0%, APC3 = 5.5%, and VS = 11.8%, with OTA/AO-61B = 74.0% and OTA/AO-61C = 26.0%. Pelvic ring mapping revealed that articular and bony injuries varied markedly between the different types of pelvic ring disruptions, both in type and location. CONCLUSIONS: Pelvic ring injury frequency maps created from unfolded CT images reflect consistent injury patterns providing distinctive information based on force vector mechanisms. Unfolded CT images allow for a novel way to visualize pelvic ring injuries which yield greater comprehension of failure patterns with implications for treatment.

Traumatic Bifocal whereas and Ipsilateral Posterior Knee Dislocation: A Case Report.

CASE: A 19-year-old man sustained combined, ipsilateral inferior hip and posterior knee fracture-dislocations secondary to a motor vehicle collision. He underwent immediate closed reduction of the knee and delayed open reduction internal fixation but required emergent open hip reduction for an irreducible femoral head incarcerated on a pubic root fracture. At the 1-year follow-up, he demonstrated excellent functional outcome with painless and full hip and knee range of motion. CONCLUSION: Irreducible inferior femoral head dislocation in combination with a knee dislocation requires thoughtful staging and treatment but can result in satisfactory outcomes.

Rib Fracture Map in High-Energy Injuries.

OBJECTIVES: To use a novel rib unfurling technology to investigate the locations of multiple rib fractures occurring from high-energy trauma to discern if there are reproducible rib fracture patterns. METHODS: Patients between the ages of 18 and 48 years presenting to a Level 1 academic trauma center with ≥2 rib fractures after a high-energy mechanism of injury between 2017 and 2019 were identified. Curved planar reformatting of CT scans was used to create two-dimensional unfurled rib images by flattening out the view of the ribs from a CT scan. Rib fractures were placed on a template map using a standardized measurement method, and subsequent frequency and heat maps were created. RESULTS: Among 100 consecutive patients, 534 fractures on 454 ribs were identified. The most common high-energy mechanism of injury was motor vehicle accidents (41%). Flail chest occurred in 8% of patients. The mean number of ribs fractured per patient was 4.54 ± 3.14 and included a mean of 5.34 ± 4.38 total fractures. Among all fractures, 50.9% were located on ribs 4 through 7. The most common fracture location was located in the lateral or anterolateral zone of the rib cage. CONCLUSIONS: Patients with multiple rib fractures from high-energy trauma have rib fractures with locations of common occurrence. An understanding of location and frequency of rib fractures can help inform surgical approaches, prognosis, indications, classifications, and implant design in the management of a complex population of patients with chest wall injury after trauma.

Does the Option to Keep Explanted Orthopaedic Trauma Implants Influence Patient Satisfaction and Perception of Care? Results of a Survey Study.

OBJECTIVE: Orthopaedic trauma implants may be electively explanted after fracture healing; reasons include symptomatic implants, cosmetic/functional concerns, or personal expectations. Certain institutions provide the option to keep implants after removal, although this has been retracted in others. This study examines patients' desire for return of implants, reasons for desiring return, and influence of return on perceptions of care. METHODS: A cohort of adult patients who underwent elective orthopaedic implant removal by a single surgeon at a Level I trauma center between 2008 and 2019, with the option to keep their removed implants, was identified. Surveys were sent to patients with contact information. Demographics, reasons for removal, satisfaction, and perceptions of care were studied. RESULTS: The overall response rate was 47.4% (117 of 247). Respondents' mean age was 46.9 years, and 50% were female. Ninety-one percent kept their implants. Eighty-nine percent of patients felt that removal achieved their desired outcome, with decreasing pain cited as primary motivation for explantation (62%). Forty-five percent reported a strong desire to keep their implants, most commonly to show to family (49%). Seventy-four percent were happy to have this option. Thirty-seven percent of patients reported respecting their provider more for having this option, and 27% reported that this positively impacted their satisfaction. CONCLUSIONS: Patients perceive elective implant removal as highly effective. A majority were pleased to have the option to keep their implants, and many reported increased respect and satisfaction. Thus, providing patients with this option should be strongly considered to honor patient choice and optimize outcomes when feasible.

Infection from an Iliosacral Screw 16 Years Postoperatively in Demolition Derby Umpire Crushed Between 2 Cars: A Case Report.

CASE: A 47-year-old man crushed between 2 cars during a demolition derby, a nonracing North American motorsport, underwent open reduction and internal fixation, iliosacral screw fixation, arterial embolization, and multiple urologic procedures after massive pelvic ring injury, remarkably recovering nearly full function. Sixteen years after injury, he developed an abscess emanating from an iliosacral screw requiring irrigation, debridement, and hardware removal. CONCLUSION: Deep surgical infections from iliosacral screws may present late, even more than 15 years after the original surgery. Obesity, preoperative embolization, diabetes, and urethral injuries are relevant risk factors. Similar patients should have a low threshold for infection workup when presenting with symptoms, even years after surgery.

Capturing patient-reported outcomes: paper versus electronic survey administration.

Objective: To compare the capture rates and costs of paper patient-reported outcomes (pPRO) administered in-clinic and electronic PROs (ePRO) collected through emails and texts. Design: Retrospective review. Setting: Level 1 trauma center. Patients/Participants: The pPRO program enrolled 2164 patients for postsurgical follow-up in 4 fracture types: ankle, distal radius, proximal humerus, and implant removal from 2012 to 2017. The ePRO program enrolled 3096 patients in 13 fracture types from 2018 to 2020. Among the patients enrolled in the ePRO program, 1296 patients were matched to the 4 original fracture types and time points. Main Outcome Measures: PRO capture rates in 4 fracture types by matched time point and estimated cost of each program per enrolled patient. Results: At first follow-up, pPRO provided a higher capture rate than ePRO for 3 of 4 fracture types except for implant removal (P < 0.05). However, at 6-month and 1-year follow-ups, ePRO demonstrated statistically significant higher capture rates when compared with pPRO for all applicable modules (P < 0.05). The average cost for the pPRO program was $171 per patient versus $56 per patient in the ePRO program. Patients were 1.19 times more likely to complete ePRO compared with pPRO (P = 0.007) after controlling for age, sex, fracture type, and time point. Conclusion: The electronic PRO service has improved long-term capture rates compared with paper PROs, while minimizing cost. A combined program that includes both in-clinic and out of clinic effort may be the ideal model for collection of PROs. Level of Evidence: Level 3.

Resection of Posttraumatic Rib Synostoses Resolves Pulmonary Insufficiency: A Case Report.

CASE: A 30-year-old woman underwent open reduction and internal fixation for multiple segmental rib fractures status post a motor vehicle collision. A year later, the patient presented with extensive intercostal heterotopic ossification associated with multilevel, hemithoracic, rib synostoses compromising her ventilation. The patient subsequently underwent synostoses excision and hardware removal. Pulmonary function tests (PFT), imaging, and patient-reported outcome scores demonstrate resolution of impairment. CONCLUSION: Resection of multilevel, intercostal, rib synostoses provided an effective treatment for pulmonary restrictive disorder secondary to traumatic rib synostosis. This is the first patient with documentation of prereconstructive and postreconstructive PFTs for chest wall synostosis excision.

Three-dimensional mapping of sternum fractures from high-energy trauma.

BACKGROUND: Sternum fractures are relatively uncommon injuries, which generally occur as a result of a high-energy mechanism and are often associated with significant concomitant injuries. These injuries may result in decreased quality of life if not properly addressed and yet are rarely operated on. The purpose of this project is to evaluate high-energy sternum fracture patterns using a previously published three-dimensional (3D) computed tomography (CT) reconstruction process to produce fracture frequency maps. METHODS: Patients 18 years and older presenting to a Level I trauma center with sternum fractures due to high-energy trauma between October 2013 and January 2022 were included. A 3D reconstruction and reduction was performed for each sternum using medical image processing software (Materialize NV, Leuven, Belgium). The reconstructions were subsequently overlaid onto a template sternum and normalized using bony landmarks. Fracture lines for each injured sternum were transferred onto the template, creating 3D frequency maps. RESULTS: A total of 120 patients met inclusion criteria. The study population had a uniform age distribution and 57.5% were male. The most common mechanism of injury was motor vehicle collision (64.2%). The breakdown of sternum fractures were isolated sternal body (55.8%), isolated manubrium (31.7%), and combined sternal body and manubrium fractures (12.5%). No xiphoid fractures were observed. Sternal body fractures were a near even mix of transverse (31.7%), oblique (32.9%), and comminuted (35.4%), while 75.5% of manubrium fractures were oblique. The most common associated injuries included rib fractures (80.8%) and traumatic brain injury (61.7%). CONCLUSION: This study presents the fractures from sternum injuries in 3D, and provides insight into reproducible sternum injury patterns that have not previously been analyzed in this format. This fracture mapping technique presents numerous injury patterns simultaneously, such that more frequent morphologies can be appreciated for different patient groups.
