All-suture fixation of syndesmotic injuries: a case series.

BACKGROUND: To retrospectively evaluate the clinical outcomes of patients treated for syndesmotic injuries with an all-suture construct technique and compare their patient reported outcome scores with historically published outcomes of syndesmotic injuries fixed with suspensory suture buttons. METHODS: This was a retrospective case series of patients treated at a Level 1 Trauma Center from May 1, 2018, to June 30, 2022. Ten patients aged 18 and older with unstable syndesmotic injuries treated with all-suture repair. Patients were excluded if they were treated with trans-osseous screws, had previous failed syndesmotic fixation, or suspensory suture button fixation. Patient-reported outcomes including Visual Analog Scale (VAS) pain scores, American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot scores, and complications were recorded. RESULTS: In the patients with 6 weeks or more of radiographic follow-up (N = 9), there was no evidence of nonunion, loss of fixation, hardware complication, or whitling of the fibula by the suture. At final follow-up average VAS pain scores were 1.5 out of 10 (range 0-4; SD 1.2), AOFAS ankle and hindfoot scores averaged 89.6 out of 100 (range 86-100; SD 6.1). The pain subscale of the AOFAS score averaged 37.5 out of 40 (range 35-40; SD 2.5). The functional subscale of the AOFAS score averaged 46 out of 50 (range 44-50; SD 3.0). Stiffness was reported in one patient at their follow-up visits, which resolved with continued physical therapy. There were no superficial or deep infections. CONCLUSIONS: In conclusion, this case series presents the first clinical outcomes of an all-suture fixation technique for treatment of unstable syndesmotic ankle injuries. Our results suggest that the all-suture fixation technique results in similar patient reported outcomes when compared with historically reported patient reported outcomes of suspensory suture button fixation, and low rates of complication or hardware failure.

Association of Pelvic Trauma With Rates of Cesarean Section, Sexual Dysfunction, and Genitourinary Dysfunction in a National Database.

INTRODUCTION: Pelvic fractures are severe injuries that can drastically affect a woman's quality of life through sexual dysfunction (SD), genitourinary dysfunction (GD), and increasing the potential need for future cesarean section (C-section). Limited research has captured long-term outcomes after pelvic fractures in women of childbearing age. This study aimed to determine the association between pelvic fractures and rates of C-section, SD, and GD. METHODS: All women of childbearing age who sustained a pelvic fracture were identified in a national insurance database. A comparison group of patients with lower extremity long-bone fractures was selected. Patients who gave birth after injury were additionally identified. A minimum of 5 years of follow-up was required for inclusion. Rates of C-section, SD, and GD were compared between cohorts. Multivariate logistic regression analysis was conducted with the inclusion of diabetes, tobacco, hypertension, obesity, and advanced maternal age. RESULTS: A total of 6,174 patients with pelvic fracture and 27,154 control fracture patients were identified. 434 patients with pelvic fracture (7.0%) and 1,258 control fracture patients (4.6%) gave birth after fracture. Patients with pelvic fracture had a significantly higher rate of C-section (50.0% versus 38.8%, P < 0.001), SD diagnosis (10.9% versus 8.8%, P < 0.001), and urinary retention diagnosis (3.5% versus 2.8%, P < 0.001). No significant difference in global GD diagnosis was identified. Multivariate analyses showed that pelvic fracture was associated with C-section (odds ratio [OR]: 1.78; 95% confidence interval [95% CI]: 1.42 to 2.23, P < 0.001), SD diagnosis (OR: 1.23; 95% CI: 1.12 to 1.35, P < 0.001), and urinary retention diagnosis (OR: 1.35; 95% CI: 1.15 to 1.57, P < 0.001). DISCUSSION: Pelvic fractures confer an intrinsic level of risk of C-section, SD, and urinary retention that is elevated beyond what would be expected from a traumatic lower extremity injury alone. Treating orthopaedic surgeons should actively counsel women regarding increased risks, openly discuss postinjury sequelae, and coordinate interspecialty care beyond initial treatment of acute trauma.

Bilateral femur fractures are associated with concomitant femoral neck fracture.

OBJECTIVE: The purpose of this study is to determine the rate of femoral neck fractures in patients who have sustained bilateral femur fractures compared to unilateral femur fractures. DESIGN AND SETTING: A retrospective review of an institutional trauma database was completed at a single level 1 trauma academic medical center. PATIENTS: All patients treated for a femur fracture between May 1, 2018 and December 31, 2020 were included. RESULTS: Twenty-one patients sustained bilateral femur fractures (11%) and 166 sustained unilateral femur fractures. Fifteen associated ipsilateral femoral neck fractures were identified. Eight of the 15 (53%) associated femoral neck fractures were observed in patients who sustained bilateral femur fractures. Eight of the 21 patients with bilateral femur fractures, 42 fractures in total, had an associated ipsilateral femoral neck fracture (38% of patients; 19% of fractures, respectively), while only seven of the 166 patients (4%) with a unilateral femur fracture had an associated femoral neck fracture (p < 0.001). Of the 208 femur fractures, 19 (9%) were open fractures. Ten of the 21 patients with bilateral femur fractures, 42 fractures in total, were identified to have an open femur fracture (48% of patients, 24% of fractures), while only nine of the 166 (5%) unilateral femur fractures were open (p < 0.001). CONCLUSIONS: Our results demonstrate an association between bilateral femur fractures, open femur fractures, and associated femoral neck fractures. Surgeons treating these injuries should maintain a high index of suspicion for associated ipsilateral proximal.

Gunshot-related lower extremity nerve injuries.

OBJECTIVE: The purpose of this study was to describe the frequency of nerve injury associated with lower extremity ballistic trauma, the associated skeletal and soft tissue injuries, and the rate of neurologic recovery. DESIGN AND SETTING: A retrospective review of an institutional trauma database was completed at a single level 1 trauma academic medical center. PATIENTS: This was an institutional review board approved retrospective cohort study of patients over 16 years of age presenting with ballistic-related traumatic injury to the lower extremities between May 2018 and May 2019. All patients identified with lower extremity ballistic trauma were included in this study. The rate of nerve palsy, associated skeletal injury, and operative fixation were recorded for each anatomic zone. Rates of associated concomitant vascular injury, fracture, and compartment syndrome were collected through a review of the electronic medical records. Chart review was performed to evaluate outcomes and nerve recovery. RESULTS: Twenty-one patients (21 extremities, 21/148, 14%) were diagnosed by attending physicians, fellowship-trained in orthopedic trauma, as having ballistic-related nerve injuries. Seventy-three percent of patients with a documented neurologic injury (11/15) demonstrated complete nerve recovery as measured by the MRC and sensory scale assessment at most recent follow-up, while the rest demonstrated no improvement in their neurologic deficits from presentation. The rate of associated vascular injury in patients with lower extremity nerve palsies was 38% (8/21). While the rate of vascular injury in the absence of neurologic injury was 3% (4/127). CONCLUSIONS: This series of lower extremity nerve injuries in a large sample of urban lower extremity ballistic trauma noted a high rate of concomitant nerve injuries. An associated diagnosis of a vascular injury appears to portend a higher risk of neurologic injury. Treating surgeons should have a high index of suspicion for associated vascular injury in patients presenting with a ballistic lower extremity nerve palsy.

Isolated ballistic femoral condyle fractures: a case series of eighteen patients.

PURPOSE: Ballistic fractures of the femoral condyles are rare injuries with limited literature to help guide treatment. The purpose of this study is to report on the presentation, management, and outcomes for patients with isolated ballistic condylar fractures. METHODS: Eighteen patients between ages 16 and 65 with low-energy ballistic injuries isolated to the femoral condyles (OTA 33B) were included, 15 with CT imaging. Clinical records and imaging were reviewed, as well as treatment strategy. Fractures were classified by AO/OTA classification. Outcome and follow-up data were gathered at outpatient appointments and telephone calls. RESULTS: Of the 18 patients, 78% were treated operatively (61% with open reduction and internal fixation, 17% with removal of foreign body alone). There were two instances of traumatic vascular injury and no neurologic injuries. Furthermore, there were no identified infections. Only 58% of the patients had follow-up for more than 6 weeks with average KOOS Jr. Score of 50, and average VAS pain score of 5.2. CONCLUSIONS: Ballistic femoral condyle fractures are rare Orthopaedic injuries seen in relatively high frequency at our institution. Most (78%) were treated operatively and with few complications. These fractures are not easily classified according to common classification schemes and may benefit from more rigorous study to guide treatment and anticipate outcomes.

Comparison of a Novel Modified All-Suture Construct versus Suspensory Suture-button Fixation in a Syndesmotic Injury Model.

OBJECTIVES: To biomechanically investigate a novel modified all-suture construct compared with commercially available suspensory button fixation for stabilization of the syndesmosis. METHODS: Eight matched pairs of cadaver lower limbs were obtained. We used a material testing machine and Optotrak optoelectronic 3D motion measurement system for testing. Syndesmotic injuries were simulated, and specimens were fixed with either a suspensory suture button or modified all-suture construct. Repaired specimens were then cyclically loaded for 500 cycles. Spatial relationship of the tibia and fibula were continuously monitored for the intact, destabilized, and repaired states. The results were analyzed using independent samples t test. RESULTS: There was no significant difference in sagittal or coronal plane translation between intact and either repair. Compared with the intact state, both repair techniques demonstrated significantly more external rotation of the fibula relative to the tibia and decreased construct stiffness. Cycling of the specimens did not significantly increase coronal or sagittal plane translation; however, external rotation of the fibula relative to the tibia increased and stiffness decreased with cycling for both repair techniques. CONCLUSIONS: Our data suggest that sagittal and coronal plane translation is no different from the intact state for both fixation techniques. However, rotation of the fibula relative to the tibia was increased, and construct stiffness was decreased compared with the intact state for both fixation techniques. These findings suggest that an all-suture construct could offer syndesmotic fixation comparable with proprietary suspensory button fixation in a cadaver model.

The Effect of Fascia Iliaca Compartment Blockade on Mortality in Patients With Hip Fractures: Systematic Review and Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: The purpose of this meta-analysis was to determine whether perioperative fascia iliaca compartment blockade (FICB) decreases mortality in patients with hip fracture. METHODS: MEDLINE (PubMed and Ovid platforms), Web of Science, EMBASE, and Cochrane Database of Systemic Reviews were screened for "fascia iliaca compartment block, hip fracture" articles in English, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, from January 1, 2005, to March 1, 2020. All relevant randomized controlled trials and cohort and case-control studies were included for analysis. Relevant article titles were identified, and their corresponding abstracts were independently reviewed by two authors for inclusion. The full-text articles were then obtained for all relevant identified abstracts and assessed for inclusion in the meta-analysis. Conflicts in quality assessment between the two independent reviewers were resolved by a consensus vote of all authors. RESULTS: Study quality was assessed objectively using the Jadad and Newcastle-Ottawa Scale. This meta-analysis was done in accordance with the PRISMA (http://links.lww.com/JAAOS/A731) and QUORUM guidelines. Quantitative synthesis analysis was done using Cochrane Reviews Review Manager (version 5.3). All analyses were completed using random-effects models and comparing the individual effect sizes within each study. DISCUSSION: Management of hip fracture pain with FICB does not markedly decrease short-term mortality. Our findings support the continued use of FICB for the management of hip fractures in geriatric patients and suggest the need for future prospective randomized controlled trials to further determine FICB's effect on short-term and long-term mortality and functional status. LEVEL OF EVIDENCE: Therapeutic level I.

Ballistic Supracondylar Distal Femur Fractures Have Lower Rates of Intra-articular Extension Than Blunt Distal Femur Fractures.

OBJECTIVES: To compare the relative frequencies of intra-articular extension of supracondylar distal femur fractures in blunt versus ballistic trauma and the diagnostic accuracy of conventional radiography in identifying intra-articular extension in these fractures. DESIGN: A retrospective review. SETTING: Urban academic trauma center. STUDY GROUP: Thirty-eight patients were included for analysis, with 19 blunt and 19 ballistic mechanism distal femur fractures. INTERVENTION: Fleiss' kappa score was calculated in determining interobserver reliability of the OTA/AO classification. Radiographic specificity and sensitivity were compared using Fischer exact testing. Quantitative data were compared using 2-tailed t-testing for continuous variables and chi-square tests for proportions. MAIN OUTCOME MEASUREMENTS: Rate of intra-articular extension of ballistic versus blunt supracondylar femur fractures. RESULTS: Seventeen of 19 patients (89.5%) with blunt trauma had intra-articular involvement compared with 5 of 19 patients (26.3%) with ballistic trauma (P = 0.001). For blunt fractures, preoperative radiographs were 94% sensitive for the detection of intra-articular extension compared with 100% sensitive for ballistic fractures (P = 1.000). We identified one case, in the blunt cohort, where the operative plan changed from intramedullary nail to open reduction and internal fixation as a result of the additional coronal plane fracture pattern identified on CT. There were no such occurrences in the ballistic cohort. CONCLUSIONS: The rate of intra-articular extension for ballistic supracondylar femur fractures is lower than blunt distal femur fracture. There were low rates of missed intra-articular fractures and changes in operative plans after reviewing CT imaging for both blunt and ballistic distal femur fractures. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
