Bladder Repair With Irrigation and Debridement and Open Reduction Internal Fixation of the Anterior Pelvic Ring Is Safe and Decreases Risk of Infection in Pelvic Ring Injuries With Extraperitoneal Bladder Ruptures.

OBJECTIVES: To determine the incidence of infection in nonoperative versus operative management of extraperitoneal bladder ruptures in patients with pelvic ring injuries. DESIGN: A retrospective cohort study of 2 prospectively collected trauma registries. SETTING: Two Level 1 trauma centers. PATIENT SELECTION CRITERIA: Patients with operative pelvic ring injuries, 68 (6%) had extraperitoneal bladder ruptures. OUTCOME MEASURES AND COMPARISONS: The primary outcome was the incidence and associated risk factors of deep pelvic infection requiring return to OR for surgical debridement. Secondary outcomes included quality of reduction, other complications, and radiographic union. Comparisons were made based on the status of any associated bladder injury. RESULTS: Of 1127 patients with operative pelvic ring injuries, 68 patients had extraperitoneal bladder ruptures, 55 had bladder repair and 13 did not. Of those 13 without repair, none had ORIF of the anterior pelvic ring. Patients without bladder repair had an increased odds of infection 17-fold compared to patients who did have a repair performed (OR 16.9, 95% CI 1.75 - 164, P = 0.01). Other associated factors for deep pelvic infection included use of suprapubic catheter ( p < 0.02) and a closed reduction of the anterior ring ( p < 0.01). Patients undergoing anterior ring ORIF and bladder repair had improved reductions and no increased infection risk. CONCLUSIONS: Operative repair of extraperitoneal bladder ruptures decreases risk of infection in patients with pelvic ring injuries. Additionally, ORIF of the anterior pelvic ring does not increase the risk of infection and results in better reductions compared to closed reduction. Treatment algorithms for these combined injuries should consider recommending early bladder repair and anterior pelvic ORIF. LEVEL OF EVIDENCE: Therapeutic Level III.

Pelvic ring injuries: recent advances in diagnosis and treatment.

Pelvic ring injuries typically occur from high-energy trauma and are often associated with multisystem injuries. Prompt diagnosis of pelvic ring injuries is essential, and timely initial management is critical in the early resuscitation of polytraumatized patients. Definitive management of pelvic ring injuries continues to be a topic of much debate in the trauma community. Recent studies continue to inform our understanding of static and dynamic pelvic ring stability. Furthermore, literature investigating radiographic and clinical outcomes after nonoperative and operative management will help guide trauma surgeons select the most appropriate treatment of patients with these injuries.

Assessment of sacral osseous fixation pathways for same-level dual transiliac-transsacral screw insertion.

INTRODUCTION: The purpose of this study is to (1) describe a pre-operative planning technique using non-reformatted CT images for insertion of multiple transiliac-transsacral (TI-TS) screws at a single sacral level, (2) define the parameters of a sacral osseous fixation pathway (OFP) that will allow for insertion of two TI-TS screws at a single level, and (3) identify the incidence of sacral OFPs large enough for dual-screw insertion in a representative patient population. METHODS: Retrospective review at a level-1 academic trauma center of a cohort of patients with unstable pelvic injuries treated with two TI-TS screws in the same sacral OFP, and a control cohort of patients without pelvic injuries who had CT scans for other reasons. RESULTS: Thirty-nine patients had two TI-TS screws at S1. Eleven patients, all with dysmorphic osteology, had two TI-TS screws at S2. The average pathway size in the sagittal plane at the level the screws were placed was 17.2 mm in S1 vs 14.4 mm in S2 (p = 0.02). Twenty-one patients (42%) had screws that were intraosseous and 29 (58%) had part of a screw that was juxtaforaminal. No screws were extraosseous. The average OFP size of intraosseous screws was 18.1 mm vs. 15.5 mm for juxtaforaminal screws (p = 0.02). Fourteen millimeters was used as a guide for the lower limit of the OFP for safe dual-screw fixation. Overall, 30% of S1 or S2 pathways were ≥ 14 mm in the control group, with 58% of control patients having at least one of the S1 or S2 pathways ≥ 14 mm. CONCLUSIONS: OFPs ≥ 7.5 mm in the axial plane and 14 mm in the sagittal plane on non-reformatted CT images are large enough for dual-screw fixation at a single sacral level. Overall, 30% of S1 and S2 pathways were ≥ 14 mm and 58% of control patients had an available OFP in at least one sacral level.

Distractor Application and Dry Arthroscopy to Improve Articular Visualization During Scapula Fracture Surgery Via a Posterior Approach.

SUMMARY: Intra-articular glenoid displacement is an indication for open reduction and internal fixation of scapular fractures. However, direct visualization of the glenoid is limited, and articular reductions are typically performed and assessed using extra-articular cortical reduction reads and fluoroscopic imaging. In this technique, we describe the application of a distractor for direct visualization of the glenoid articular surface. In this way, anatomic reduction of the glenoid articular surface can be assessed and achieved. In addition, we discuss the use of a portable, dry arthroscopy when needed. This technique has resulted in good-to-excellent articular reductions by adjusting extra-articular reads that seemed adequate before intra-articular visualization. This technique is safe, requires minimal extra set-up or instruments, and results in good-to-excellent articular reductions.

Treatment of Segmental Bone Defects Biology and Treatment Options.

Segmental bone defects (SBD) are difficult to treat, requiring a comprehensive understanding of the bone and soft tissue injury. Defect size, fracture characteristics, and local and systemic biology all help dictate treatment options. Bone grafting with autograft or allograft, Masquelet technique, and bone transport with external or internal fixation can all be used successfully in the correct patient. When deciding on the best treatment option and addressing any complications throughout the process, it is important to always keep in mind the three principles of bone healing: sterility, stability, and biology. The goal of this review is to present the history of treatment for critical SBD, including the indications and challenges that have been addressed and current and emerging treatment options.

Open Reduction and Internal Fixation of Pediatric Scapula Fractures: A Report of 2 Cases.

CASE: Two pediatric patients with displaced, extra-articular scapula fractures who underwent surgery because of concerns for persistent deformity and decreased function with continued nonoperative management. CONCLUSION: We advocate careful consideration of all patient factors and treatment options when addressing pediatric scapula fractures. Specific fracture patterns with altered shoulder girdle mechanics may warrant surgical intervention to restore anatomic alignment and stability.

Symptomatic Ischial Stress Fractures in Elite Athletes Treated With Percutaneous Screws: A Report of 2 Cases.

CASES: Two high-level athletes with symptomatic gluteal pain with explosive movements that had failed nonoperative management were eventually diagnosed with ischial stress fractures. These were treated with percutaneous posterior column screws. Both patients healed their fractures and made full return to sport. CONCLUSION: Ischial stress fractures should be considered in the differential for athletes with persistent gluteal pain. Percutaneous fixation is a minimally invasive and effective method of treating symptomatic ischial stress fractures that have failed nonoperative treatment.

Conversion total hip arthroplasty for early failure following unstable intertrochanteric hip fracture: what can patients expect?

PURPOSE: To report surgical outcomes in patients treated with conversion total hip arthroplasty (CTHA) for early failure of cephalomedullary nails (CMNs). METHODS: A retrospective review was conducted of CTHA for treatment of failed CMN within 1 year of initial surgery for intertrochanteric (IT) hip fractures. The cohort was matched 1:5 to patients who underwent elective primary THA (PTHA). Patient demographics, mechanism of CMN failure, surgical outcomes, and complication rates were assessed. RESULTS: 22 patients met criteria with a mean time to failure of 145 days. Modes of failure included: lag screw cut-out with superior migration (9, 40.9%), or medialization (8, 36.4%), and aseptic nonunion with implant failure (2, 9.0%) and without implant failure (3, 13.6%). Fourteen of the patients (63.6%) had acetabular-sided damage secondary to lag screw penetration, all in the screw cut-out groups. Patient demographics were similar between cohorts. Compared to PTHA, CTHA patients had increased operative time, blood loss, LOS, and readmission rates. After IMN failure, the operative leg was shorter than the contralateral leg in all cases. CTHA restored leg lengths to < = 10 mm in 15 (68.1%) of patients, with an average leg length discrepancy after CTHA of 6.7 mm. CTHA patients had increased rates of overall surgical complications and medical complications, specifically anemia (all p < 0.01). Tranexamic acid was used less often in the CTHA group (p < 0.01). Rate of periprosthetic joint infection (PJI), dislocation, and revision were all higher in the CTHA, though did not reach statistical significance. CONCLUSION: The majority (77.3%) of CMN implant failure for nonunion within 1 year was due to screw cut-out. CTHA is a salvage option for early failed IT hip fracture repair, but expected surgical outcomes are more similar to revision THA than primary THA, with increased risk of readmission, longer surgery and LOS, increased blood loss, and higher complication rates.

Tendency of Driving to the Basket Is Associated With Increased Risk of Anterior Cruciate Ligament Tears in National Basketball Association Players: A Cohort Study.

BACKGROUND: Driving to the basket in basketball involves acceleration, deceleration, and lateral movements, which may expose players to increased anterior cruciate ligament (ACL) injury risk. It is unknown whether players who heavily rely on driving have decreased performance on returning to play after ACL reconstruction (ACLR). HYPOTHESIS: Players with a greater tendency to drive to the basket would be more likely to tear their ACL versus noninjured controls and would experience decreased performance when returning to play after ACLR. STUDY DESIGN: Case-control study; Level of evidence, 3. METHODS: Season-level performance statistics and ACL injuries were aggregated for National Basketball Association (NBA) seasons between 1980 and 2017 from publicly available sources. Players' tendency to drive was calculated using 49 common season-level performance metrics. Each ACL-injured player was matched with 2 noninjured control players by age, league experience, and style of play metrics. Points, playing minutes, driving, and 3-point shooting tendencies were compared between players with ACL injuries and matched controls. Independent-samples t test was utilized for comparisons. RESULTS: Of 86 players with a total of 96 ACL tears identified in the NBA, 50 players were included in the final analysis. Players who experienced an ACL tear had a higher career-average drive tendency than controls (P = .047). Players with career-average drive tendency ≥1 standard deviation above the mean were more likely to tear their ACL than players with drive tendency <1 standard deviation (5.2% vs 2.7%; P = .026). There was no significant difference in total postinjury career points (P = .164) or career minutes (P = .237) between cases and controls. There was also no significant change in drive tendency (P = .152) or 3-point shooting tendency (P = .508) after return to sport compared with controls. CONCLUSION: NBA players with increased drive tendency were more likely to tear their ACL. However, players who were able to return after ACLR did not underperform compared with controls and did not alter their style of play compared with the normal changes seen with age. This information can be used to target players with certain playing styles for ACL injury prevention programs.

Shoulder Hemiarthroplasty for Proximal Humerus Fracture.

SUMMARY: There are a variety of treatment options available for proximal humerus fractures, including nonoperative management, open reduction internal fixation with screws, locking plates, intramedullary nailing, or suture fixation, and arthroplasty, including hemiarthroplasty and total shoulder replacements. Fracture characteristics, including the number of fracture parts and involvement of the humeral head and glenoid and the patient's functional status and postoperative goals help dictate the optimal choice. Although the indications for hemiarthroplasty as treatment for severe proximal humerus fractures have narrowed, the authors believe that there is a still a place for this technique in practice.

Repair of Humeral Shaft Nonunion With Plate and Screw Fixation and Iliac Crest Bone Graft.

SUMMARY: A 58-year-old woman with a proximal 1/3 humeral shaft nonunion presented 2 years after initial injury. We present a technique for nonunion repair, including nonunion site preparation, direct compression of the fracture site using plate osteosynthesis, and iliac crest bone graft harvest and utilization. The purpose of this video is to review humeral shaft nonunion literature and describe our management technique.

Treatment of a Chronic Elbow Dislocation With an Internal Fixator.

SUMMARY: There are a variety of ways to treat chronic elbow dislocations, including repeat closed reduction and immobilization, transarticular pinning, temporary bridge plating, hinged or rigid external fixation, and internal fixator application. Although each have distinct advantages and disadvantages, avoiding recurrent instability is critical. The internal-fixator is a relatively new option to maintain a stable, concentric reduction and facilitate early range of motion. This article and accompanying video describe the surgical technique of using an internal joint stabilizer for treatment of a chronically unstable ulnohumeral joint.

Staged Reconstruction of a Moore Type 4 Fracture Dislocation, Parts 1 and 2.

SUMMARY: High-energy tibial plateau fractures are associated with knee fracture dislocations and concomitant ligamentous injury. Both bony and ligamentous injuries can require surgical fixation, often requiring a multidisciplinary team and staged treatment. This article and accompanying video describe the workup and treatment of a Moore type 4 tibial plateau rim compression fracture with posterolateral corner and anterior cruciate ligament rupture that underwent open reduction internal fixation of the tibial plateau with posterolateral corner reconstruction and then staged anterior cruciate ligament reconstruction with quad tendon autograft.

White-Light Body Scanning Captures Three-Dimensional Shoulder Deformity After Displaced Diaphyseal Clavicle Fracture.

OBJECTIVE: We sought to determine if white-light three-dimensional (3D) body scanning can identify clinically relevant shoulder girdle deformity after displaced diaphyseal clavicle fracture (DCF). METHODS: Adult patients with DCF (OTA/AO 15A) were prospectively enrolled. Four subcutaneous osseous landmarks were used to measure shoulder girdle morphology of the injured and uninjured shoulder. Measurements were made both manually with a tape measure and digitally with a white-light 3D scanner. Bilateral radiographs were obtained, and clavicle length was recorded. Quick-Disabilities of the Arm, Shoulder, and Hand surveys were administered at injury and at 6 and 12 weeks. RESULTS: Twenty-two patients were included in the study. At the initial visit, all patients had significant differences in deformity measurements between injured and uninjured shoulders as measured by 3D scanning. There was no difference between shoulders measured using manual measurements. At 6 and 12 weeks, shoulder asymmetry was significantly less in patients treated with surgery compared with nonoperative patients as measured by the 3D scanner alone. Clavicle shortening measured on 3D scanning had weak and moderate positive correlations to radiographs (R = 0.27) and manual measurements (R = 0.53), respectively. Patients treated with surgery had significant functional improvements by 6 weeks, and a similar improvement was not seen until 12 weeks in nonsurgical patients. CONCLUSION: White-light 3D scanning was able to identify and monitor clinically relevant shoulder girdle deformity after DCF. This tool may become a useful adjunct to clinical examination and radiographic assessment, when determining clinically relevant deformity thresholds. In the future, quantifying and understanding shoulder deformity may inform clinical decision making in these patients. LEVEL OF EVIDENCE: Prognostic Level IV.

Patient-Reported Outcome Measures (PROMs): Influence of Motor Tasks and Psychosocial Factors on FAAM Scores in Foot and Ankle Trauma Patients.

Patient-reported outcome measures (PROMS) are being increasingly used as a quality of care metric. However, the validity and consistency of PROMS remain undefined. The study sought to determine whether Foot and Ankle Ability Measure (FAAM) scores improve after patients complete motor tasks evaluated on the survey and to examine the relationship between depression and self-efficacy and FAAM scores or change in scores. We conducted a prospective comparison study of adults with isolated foot, ankle, or distal tibia fractures treated operatively at level I trauma center. Twenty-seven patients completed the FAAM survey at the first clinic visit after being made weightbearing as tolerated (mean 3 months). Patients then completed 6 motor tasks queried on FAAM (standing, walking without shoes, squatting, stairs, up to toes), followed by a repeat FAAM and General Self-Efficacy scale (GSE) and Patient Health Questionnaire-2 (PHQ-2) instruments. FAAM scores before and after intervention; GSE and PHQ-2 scores compared with baseline FAAM and change in FAAM scores. Performing motor tasks significantly improved postintervention scores for squatting (P = .044) and coming up to toes (P = .012), the 2 most strenuous tasks. No difference was found for the remaining tasks. Higher depression ratings correlated with worse FAAM scores overall (P < .05). Higher self-efficacy ratings correlated with increase in FAAM Sports subscale postintervention (P = .020). FAAM scores are influenced by performing motor tasks. Self-reported depression influences baseline FAAM scores and self-efficacy may influence change in FAAM scores. Context and patient factors (modifiable and nonmodifiable) affect PROM implementation, with implications for clinical care, reimbursement models, and use of quality measure.

Locking Screws With a Threaded Degradable Polymer Collar Reduce Construct Stiffness Over Time.

OBJECTIVES: The stiffness of locking plates provide increased stability for early fracture healing but may limit late interfragmentary motion (IFM) necessary for secondary bone healing. An ideal plating construct would provide early rigidity and late flexibility to optimize bone healing. A novel screw plate construct utilizing locking screws with a degradable polymer locking mechanism is a dynamic option. METHODS: Conventional locked plating constructs (group A) were compared with locking screws with a threaded degradable polymer collar before (group B) and after polymer dissolution (group C). Monotonic axial compression, monotonic torsion, cyclic axial load to failure, and IFM at the near and far cortices were tested on synthetic bone models. RESULTS: One-way analysis of variance and post hoc Tukey-Kramer testing demonstrated similar axial stiffness in group A (873 ± 146 N/mm) and B (694 ± 314 N/mm) but significantly less stiffness in group C (379 ± 59 N/mm; F(2,15) = 9.12, P = 0.003). Groups A and B also had similar IFM, but group C had significantly increased IFM at both the near (F(2, 15) = 48.66, P = 2.76E-07) and far (F(2, 15) = 11.78, P = 0.0008) cortices. In cyclic axial load to failure, group A (1593 ± 233 N) and B (1277 ± 141 N) were again similar, but group C was significantly less (912 ± 256 N; F(2, 15) = 15.00, P = 0.0003). All failures were above the 500-N threshold seen in typical weight-bearing restrictions for fracture care. Torsional stiffness demonstrated significant differences between all groups (F(2, 15) = 106.64, P = 1.4E-09). CONCLUSIONS: Use of locking plates with a degradable polymer collar show potential for in vitro construct dynamization. Future in vivo studies are warranted to assess performance under combined loading and the effects of decreasing construct stiffness during the course of bony healing.

The Not-So-Simple Ankle Fracture: Avoiding Problems and Pitfalls to Improve Patient Outcome.

Ankle fractures are among the most common fractures encountered by orthopaedic surgeons and, in the setting of tibiotalar instability, are usually treated surgically. Although orthopaedic surgeons from diverse educational backgrounds often feel comfortable treating such fractures, many controversies and clinical challenges remain. A detailed understanding of the unique issues presented by each patient as well as the best available treatments are required to optimize outcome. Given the unforgiving soft-tissue envelope and the particular importance of both precise reduction and absolute stability, poorly conceived and executed surgery will predictably end in compromised patient outcomes. The purpose of this manuscript is to update practicing surgeons on the best strategies for improving patient outcome after ankle fracture. The focus will be on some of the more nuanced, controversial, and complex ankle fracture-related topics, both in terms of decision making and technical execution. These will include the optimal management of posterior malleolus fractures and syndesmosis injuries as well as the best strategies to minimizing risks in poor hosts such as diabetics, obese patients, and the frail elderly. We will also provide a framework with which surgeons can approach the salvage of patients in whom the initial management has failed.

Controversies in Fracture Healing: Early Versus Late Dynamization.

Dynamization of fracture fixation constructs provides early rigidity for primary bone healing and late motion for secondary healing. A review of laboratory, animal, and clinical studies investigating the impact, and optimal timing, of dynamization is limited by lack of standardization across studies. However, in animal models, dynamization improves histologic and biomechanical properties compared with statically rigid or flexible controls. In animals, dynamization at 3 to 4 weeks showed improved histologic results. In clinical studies, it showed faster, stronger, and stiffer bone healing. Clinical success dynamizing external fixators and intramedullary nails suggests a role for late dynamization in other fixation types, such as bridge plating. [Orthopedics. 2020;43(3):e125-e133.].

Early Postoperative Radiographs Have No Effect on Orthopaedic Trauma Patient's Satisfaction With Their Clinic Visit.

BACKGROUND: Patient satisfaction plays a prominent role in modern orthopaedic care, reimbursement, and quality assessment, even if it runs contrary to the "standard of care." The literature shows that routine early radiographs after acute fracture care have no impact on clinical decision-making or patient outcomes, but little is known about their effect on patient satisfaction and understanding of their injuries. We hypothesized that eliminating these radiographs would negatively influence patient satisfaction scores with their clinic visit. METHODS: One hundred patients were prospectively enrolled after acute fracture fixation. Half the patients obtained radiographs at the 2-week follow-up visit, whereas the other half did not. All patients completed a satisfaction survey about their clinic visit. RESULTS: No difference was observed between the groups in overall satisfaction with the clinic visit (P = 0.62) or complications. However, patients with radiographs were more satisfied with the surgeon's explanations of their injury and progression (P = 0.03). CONCLUSION: Eliminating routine early postoperative radiographs had no effect on overall patient satisfaction with the clinic visit, but it did affect satisfaction with the surgeon's explanation of their injury. This could save time, money, and radiation exposure without adversely affecting patient outcome or satisfaction, but an equivalent educational tool should be identified for clinic visits.

Successful Implementation of an Accelerated Recovery and Outpatient Total Joint Arthroplasty Program at a County Hospital.

Outpatient and accelerated recovery total joint arthroplasty (TJA) programs have become standard for private and academic practices. County hospitals traditionally serve patients with limited access to TJA and psychosocial factors which create challenges for accelerated recovery. The effectiveness of such programs at a county hospital has not been reported. METHODS: In 2017, our county hospital implemented an accelerated recovery protocol for all TJA patients. This protocol consisted of standardized, preoperative medical and psychosocial optimization, perioperative spinal anesthesia, tranexamic acid and local infiltration analgesia use, postoperative emphasis on non-narcotic analgesia, and early mobilization. LOS, complications, disposition, and cost were compared between patients treated before and after protocol implementation. RESULTS: In 15 months, 108 primary TJA patients were treated. Compared with the previous 108 TJA patients, LOS dropped from 3.4 to 1.6 days (P < 0.001), more patients discharged home (92% versus 72%, P < 0.001), average hospitalization and procedure-specific costs decreased 24.7% and 22.1%, respectively, and were significantly fewer complications (7% versus 21%, P = 0.007). CONCLUSIONS: Implementation of an accelerated recovery TJA program at a County Hospital is novel. This implementation requires careful patient selection and a coordinated multidisciplinary approach and is a safe and cost-effective method of delivering high-quality care to an underserved cohort.
