Pedestrians injuries in the north east region of Jamaica: a cross sectional study

To describe the sociodemographic data of injured pedestrians, temporal patterns of injury, injury patterns, and the independent predictors of hospital admission. A two year cross-sectional study was conducted at the Saint Ann’s Bay Regional Hospital in pedestrians with injuries post collision with a motor vehicle. A census was performed in all patients who received either emergency room treatment, hospital admission, or surgical intervention. A 30-item interviewer questionnaire was administered to collect the data. A logical regression model was used to determine independent predictors for hospital admission. Ninety pedestrians were included. Age range: 6-86 years old (Mean=39.9). Males were 63.3%, 75.6% were employed, 31% had a chronic illness and 27% reported marijuana use. Most injuries occurred in April, lowest injury rates occurred in August and September. Twenty two percent of collisions occurred on Saturdays. Most injuries occurred at 5pm and 3pm. Many (54.4%) had a fracture, 73.5% were closed. Approximately 32% had contusions and 6.7% had lacerations. Independent predictors of admission were history of marijuana use and having a fracture. Those with history of marijuana use were 4.21 times more likely to be admitted. Those with fractures were 7.10 times more likely to be admitted. Injury patterns spanned a wide age range. They often involved a high energy mechanism of injury as evidenced by the frequency of fractures, hospital admission and surgery intervention rates. The data also suggests a need to implement marijuana testing programmes in our road users.

364 Traumatic Dens Fracture Patients Comprise Distinct Subpopulations Distinguished by Differences in Age, Sex, and Injury Mechanism and Severity

INTRODUCTION: Dens fractures are an increasingly common cervical fractures, yet their epidemiology and its implications remain under-examined. METHODS: We retrospectively analyzed all traumatic dens fracture patients managed at our institution over a ten year period with respect to demographic, clinical, and outcomes data. Patient subsets were compared across these parameters. RESULTS: 303 traumatic dens fracture patients were identified, who showed a bimodal age distribution with strong goodness of fit centered at age 22.3 ± 5.7 (R = 0.8781) and at 77.7 ± 13.9 (R = 0.9686). A population pyramid demonstrated a bimodal distribution among male patients, but not among female patients, which was confirmed with a strong goodness of fit for two distinct male patient subpopulations age <35 (R = 0.9791) and age =35 (R = 0.8843), but a weak fit for a second female subpopulation age <35 (24.5 ± 14.2, R = 0.5957). Patients age <35 were more likely to be male (82.4% vs. 46.9%, OR = 5.29 [1.54, 17.57], p = 0.0052). Moreover, patients age <35 were more likely to have MVC as their mechanism of injury (64.7% vs. 14.1%, OR = 11.18 [3.77, 31.77], p < 0.0001), were more likely to have a severe trauma injury severity score (17.6% vs. 2.9%, OR = 7.23 [1.88, 28.88], p = 0.0198). There was no difference with respect to underlying fracture morphology, likelihood of undergoing surgery, having concomitant atlas or subaxial fractures, or Nurick scores at presentation. Patients age <35 were less likely to have fracture nonunion at follow (18.2% vs. 53.7%, OR = 0.19 [0.041, 0.76], p = 0.0288). CONCLUSIONS: The dens fracture patient population comprises two subpopulations, distinguished by differences in age, sex, and injury mechanism and severity, with male dens fracture patients demonstrating a bimodal age distribution. While young patients were more likely to high-energy injury mechanisms leading severe trauma, they were less likely to have fracture nonunion at follow up.

Talar Neck Fractures With Associated Ipsilateral Foot and Ankle Fractures Have a Higher Risk of Avascular Necrosis.

To determine if talar neck fractures with concomitant ipsilateral foot and/or ankle fractures (TNIFAFs) are associated with higher rates of avascular necrosis (AVN) compared with isolated talar neck fractures (ITNs). Retrospective cohort. Single level I trauma center. Skeletally mature patients who sustained talar neck fractures from January 2008 to January 2017 with at least 6-month follow-up. Based on radiographs at the time of injury, fractures were classified as ITN or TNIFAF and by Hawkins classification. The primary outcome was the development of AVN based on follow-up radiographs, with secondary outcomes including nonunion and collapse. There were 115 patients who sustained talar neck fractures, with 63 (55%) in the ITN group and 52 (45%) in the TNIFAF group. In total, 63 patients (54.7%) were female with the mean age of 39 years (range, 17-85), and 111 fractures (96.5%) occurred secondary to high-energy mechanisms of injury. There were no significant differences in demographic or clinical characteristics between groups ( P > 0.05). Twenty-four patients (46%) developed AVN in the TNIFAF group compared with 19 patients (30%) in the ITN group ( P = 0.078). After adjusting for Hawkins classification and other variables, the odds of developing AVN was higher in the TNIFAF group compared with the ITN group [odds ratio, 2.43 (95% confidence interval, 1.01-5.84); ( P = 0.047)]. This study found a significantly higher likelihood of AVN in patients with talar neck fractures with concomitant ipsilateral foot and/or ankle fractures compared to those with isolated talar neck fractures after adjusting for Hawkins classification and other potential prognostic confounders. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

GENESIS OF TRAUMA IN PATIENTS WITH LONG BONE FRACTURES COMPLICATED UNDER COVID-19

Traumatology is one of the branches of medicine that cannot suspend its activities, despite the danger of the COVID-19 epidemic. Treatment of skeletal bone fractures in patients with COVID-19, given the novelty of this problem, is one of the most difficult tasks of modern traumatology and orthopaedics. Bone fractures against the background of COVID-19 are characterized not only by high mortality and disability, but also by unpredictable progression. The aim of our study was to study the impact of the mechanism of occurrence and traumatogenesis of long bone fractures in patients with COVID-19. To carry out the research tasks, we formed a retrospective study array, which consisted of 289 cases of skeletal bone fractures, which were treated at the "Kyiv City Clinical Hospital of Emergency Medical Care" from March 2020 to February 2021. The main mechanism of injury in patients with skeletal bone fractures against COVID-19 was a fall from a height, which was observed 1.5 times more often than in the pre-war period. There was a 10% reduction in high-energy injury mechanisms such as falls from height and direct impact during the epidemic period, and an almost 10% increase in low-energy compression injury mechanisms. Among the patients of the main group, the combination of lighter mechanisms of injury such as falling and compression was more often detected, in contrast to the patients of the control group, where more high-energy mechanisms of trauma from a fall and a direct blow prevailed. During the COVID-19 epidemic, domestic injuries as a cause of fractures increased sharply and the specific gravity of road accidents decreased sharply, which is associated with epidemic restrictions. During the period of the COVID-19 epidemic, industrial injuries significantly decreased, while criminal and combined injuries remained at the same level as before the epidemic.

Traumatic Dens Fracture Patients Comprise Distinct Subpopulations Distinguished by Differences in Age, Sex, Injury Mechanism and Severity, and Outcome

Dens fractures are an increasingly common injury, yet their epidemiology and its implications remain underexamined. We retrospectively analyzed all traumatic dens fracture patients managed at our institution over a 10-year period, examining demographic, clinical, and outcomes data. Patient subsets were compared across these parameters. Among 303 traumatic dens fracture patients, we observed a bimodal age distribution with a strong goodness of fit centered at age 22.3 ± 5.7 (R= 0.8781) and at 77.7 ± 13.9 (R= 0.9686). A population pyramid demonstrated a bimodal distribution among male patients, but not female patients, which was confirmed with a strong goodness of fit for male patient subpopulations age <35 (R= 0.9791) and age ≥35 (R= 0.8843), but a weaker fit for a second female subpopulation age <35. Both age groups were equally likely to undergo surgery. Patients younger than age 35 were more likely to be male (82.4% vs. 46.9%, odds ratio [OR]= 5.29 [1.54, 17.57], P= 0.0052), have motor vehicle collision as their mechanism of injury (64.7% vs. 14.1%, OR= 11.18 [3.77, 31.77], P < 0.0001), and to have a severe trauma injury severity score (17.6% vs. 2.9%, OR= 7.23 [1.88, 28.88], P= 0.0198). Nevertheless, patients age <35 were less likely to have fracture nonunion at follow (18.2% vs. 53.7%, OR= 0.19 [0.041, 0.76], P= 0.0288). The dens fracture patient population comprises 2 subpopulations, distinguished by differences in age, sex, injury mechanism and severity, and outcome, with male dens fracture patients demonstrating a bimodal age distribution. Young, male patients were more likely to have high-energy injury mechanisms leading to severe trauma, yet were less likely to have fracture nonunion at follow-up.

Direct Anterior Approach Total Hip Arthroplasty Is Associated With Reduced 1-Year Mortality and Surgical Complications After Femoral Neck Fracture

BackgroundIn some studies, the direct anterior approach (DAA) for elective total hip arthroplasty (THA) is associated with decreased dislocation and greater functional gains compared to the posterior approach (PA), as well as higher functional outcomes compared to the direct lateral approach (LA) at 2 weeks postoperatively. Given the paucity of literature on femoral neck fracture (FNF), we aspired to determine the association between the surgical approach used in THA and outcomes. MethodsWe conducted a retrospective review of patients undergoing THA for FNF at 9 institutions from 2010 to 2019. Patients who had high-energy injury mechanisms, were nonambulatory prior to injury, had concomitant femoral head or acetabular fractures, or did not reach minimum 1-year follow-up were excluded. The study included 622 THAs, of which 348 (56%) were performed through a DAA, 197 (32%) through a PA, and 77 (12%) through an LA. Postoperative complications and mortalities at 90 days and 1 year were compared between groups. Multivariable logistic regression models were constructed for each outcome of interest. ResultsThe DAA was associated with a decreased risk of 90-day dislocation (odds ratio [OR] 0.25; 95% confidence interval [CI] 0.10 to 0.62; P = .01), mechanical revision (OR 0.12; 95% CI 0.02 to 0.56; P = .01), and mortality (OR 0.38; 95% CI 0.16 to 0.91; P = .03) compared to the PA. The DAA was also associated with decreased risk of dislocation (OR 0.32; 95% CI 0.14 to 0.74; P = .01), mechanical revision (OR 0.22; 95% CI 0.08 to 0.65; P = .01), and mortality at 1 year compared to PA (OR 0.43; 95% CI 0.21 to 0.85; P = .02). ConclusionThe DAA for THA after FNF is associated with higher in-hospital medical complications but lower risks of postoperative reoperation and mortality. Postdischarge care may impact this association and needs to be addressed in future studies. The DAA should be used among surgeons experienced with the approach for FNF to minimize complications.

Upper cervical spine fracture patterns and blunt cerebrovascular injuries.

To determine patterns of C1 and C2 vertebral fractures that are associated with blunt cerebrovascular injury (BCVI). Retrospective chart review of clinical and imaging reports at a level 1 trauma center over 10 consecutive years was conducted in patients with C1 and C2 fractures. Student t-test and chi-squared analyses were used to determine associations between fracture levels and fracture types with the presence of BCVI on CTA and/or MRI or stroke on CT and/or MRI. Multilevel fractures were associated with higher incidence of BCVI compared to isolated C1 or C2 fractures (p < 0.01), but not with stroke (p = 0.16). There was no difference in incidence of BCVI or stroke between isolated C1 and isolated C2 fractures (p = 0.46, p = 0.25). Involvement of the transverse foramen (TF) alone was not associated with BCVI or stroke (p = 0.10-0.40, p = 0.34-0.43). However, TF fractures that were comminuted or contained fracture fragment(s) were associated with increased BCVI (p < 0.01, p = 0.02), though not with stroke (p = 0.11, p = 0.09). In addition, high-energy mechanism of injury was also associated with BCVI (p < 0.01) and stroke (p < 0.01). C1 and C2 fractures are associated with BCVI in the presence of high-energy mechanism of injury, concomitant fractures of other cervical vertebral body levels, comminuted TF fractures, or TF fractures with internal fragments. Attention to these fracture parameters is important in evaluating C1 and C2 fractures for BCVI.

The Rib Fracture Map in Patients with High-Energy Mechanisms of Injury.

The objective of this study was 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. Patients between the ages of 18 and 48 presenting to a Level 1 academic trauma center with ≥ 2 rib fractures following 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. 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 ribcage. 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 following trauma.

Case Report-Traumatic L5-S1 Instability: Are Upright Radiographs Potentially Dangerous?

Traumatic lumbosacral instability is a rare but potentially devastating injury. These injuries are frequently associated with neurologic injury and often result in long-term disability. Despite their severity, radiographic findings can be subtle, and multiple reports exist in which these injuries were not recognized on initial imaging. Transverse process fractures, high-energy mechanisms, and other injury features have been suggested as indications for advanced imaging, which has a high degree of sensitivity in detecting unstable injuries. A 21-year-old man presented to our level I trauma center after being ejected in a rollover motor vehicle collision. He sustained multiple injuries, including multiple lumbar transverse process fractures and a unilateral superior articular facet fracture of S1. Initial supine computed tomography (CT) images showed no displacement of the fracture and no listhesis or instability. Subsequent upright imaging in a brace, however, demonstrated significant displacement of the fracture with dislocation of the contralateral L5-S1 facet joint and significant anterolisthesis. The patient underwent open posterior reduction and stabilization of L4-S1 followed by L5-S1 anterior lumbar interbody fusion. The patient demonstrated excellent alignment on postoperative imaging. At 3 months postoperatively, he had returned to work, was ambulating without assistance, and reported minimal back discomfort and no lower extremity pain, numbness, or weakness. This case serves as a warning that supine CT imaging alone may not be sufficient to rule out unstable lumbar spine injuries, such as traumatic L5-S1 instability, and that upright radiographs in these potentially unstable injuries may represent a hazard to patients. Fractures involving the pedicle, pars, or facet joints as well as multiple transverse process fractures and/or a high-energy mechanism of injury should all raise suspicion of instability and warrant additional imaging. This article provides guidance on approaching treatment for patients with potential traumatic lumbosacral instability.

Technical Trick: T-Bar External Fixator for Definitive Management of Periarticular and Metadiaphyseal Tibial Fractures

Purpose: Tibia fractures with soft tissue compromise present are challenging to manage. For fractures with significant swelling or open injury not amenable to internal stabilization, external fixators provide sufficient stability for bony healing. Ring fixators and hybrid constructs provide adequate stability for healing but are costly, and challenging to apply and maintain. We present the “T-bar” external fixator, a novel construct that can be maintained until bony union and allows for range of motion of adjacent joints. We also report the demographics, clinical, and radiographic outcomes of 34 patients treated definitively with this construct. Materials and Methods: The T-bar external fixator uses standard pins and bars in a novel arrangement. It can be applied for Arbeitsgemeinshaft fur Osteosynthesefragen/Orthopaedic Trauma Association-type 41/42/43 type injuries, with or without supplemental fixation for intra-articular patterns. Results: Between 2008 and 2015, 34 patients were treated for tibia fracture with T-bar external fixation, with intention to treat in a definitive manner. Twenty-nine were male, and average age was 44.3 years. Thirty-one sustained high energy mechanisms of injury. Twenty were Gustilo-type 2 or 3 fractures. Of 14 closed fractures, 12 were Tscherne-type 2 or 3. Conclusions: The T-bar external fixator offers an alternative to ring and hybrid external fixator constructs in treatment of tibia fractures with significant soft tissue compromise. Of 28 patients with complete follow up, only 1 case of osteomyelitis was reported. All patients were managed without amputation. Three required revision for nonunion, all Arbeitsgemeinshaft fur Osteosynthesefragen/Orthopaedic Trauma Association-type 43.

Neck Symptoms and Associated Clinical Outcomes in Patients Following Concussion.

To examine the frequency and association of neck pain symptoms in patients with a concussion. Three-hundred and thirty-one consecutively enrolled patients aged 9 to 68 years with a diagnosed concussion 1 to 384 days post-injury were enrolled at a concussion clinic from a single integrated healthcare system in Western Pennsylvania between 2019 and 2021. Retrospective cohort analysis of prospectively collected concussion screening tool intake survey responses and clinical outcomes data. The primary outcome was self-reported neck pain or difficulty with neck movement on the Concussion Clinical Profiles Screening (CP Screen) tool, recovery time, and incidence of treatment referral. Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) composite scores, Vestibular/Ocular Motor Screening (VOMS) item scores, type and severity of neck symptoms, mechanism of injury, time from injury to clinic presentation, medical history, and concussion symptom profile were secondary outcomes. Of the 306 consecutively enrolled eligible patients in the registry, 145 (47%) reported neck pain, 68 (22.2%) reported difficulty moving their neck, and 146 (47.7%) reported either symptom. A total of 47 (15.4%) participants reported more severe neck symptoms, and this group took longer to recover (40 ± 27 days) than those not reporting neck symptoms (30 ± 28 days; U = 8316, P < .001). Stepwise logistic regression predicting more severe neck symptoms was significant (Nagelkerke R2 = 0.174, χ 2 = 9.315, P = .316) with older age ( P = .019) and mechanism of injury including motor vehicle collisions (MVCs) ( P = .047) and falls ( P = .044) as risk factors. MVCs and falls were associated with over 4 times and 2 times greater risk, respectively, for reporting more severe neck symptoms. Neck pain and stiffness symptoms are common in patients with a concussion following high-energy mechanisms of injury including MVCs or falls from height. These symptoms are associated with prolonged recovery. Providers should evaluate neck symptoms and consider targeted treatment strategies to limit their effects in patients with a concussion.

Spinopelvic dissociation: extended definition, physical examination, classification, and therapy

BackgroundSpinopelvic dissociation (SPD) is generally caused by high-energy injury mechanisms, and, in the absence of timely diagnosis and treatment, it can lead to chronic pain and progressive deformity. However, SPD is difficult to manage because of its rarity and complexity. In this study, we re-defined SPD according to the mechanism of injuries and biomechanical characteristics of the posterior pelvic ring and developed new classification criteria and treatment principles based on the classification for SPD.MethodsBetween June 2015 and September 2020, 30 patients with SPD which were selected from 138 patients with pelvic fractures were enrolled. Physical examination was performed, classification criteria (301 SPD classification) were developed, and specific treatment standards were established according to the classifications.ResultsThe injury mechanisms and co-existing injuries did not significantly differ between the classical SPD patients and expanded SPD patients. The 301 SPD classification criteria covered all the patients. Fixation by biplanar penetration screws was used in 7 patients, 11 patients received fixation by uniplanar penetration screws, 6 patients used sacroiliac compression screws, 3 patients received uniplanar screws combined with sacroiliac compression screws, and open spondylopelvic fixation was used in only 3 patients. According to the Matta criteria, 19, 7, and 4 patients achieved excellent, good, and fair reduction. The Majeed function score of the patients ranged from 9 to 96 points, and the mean score was 72.9 ± 24.6 points.ConclusionThe expanded definition for SPD is particularly significant for definite diagnosis and prevention of missing diagnosis, based on which the 301SPD classification criteria can more systemically guide the clinical treatment of SPD, increase the treatment efficacy, and reduce surgical trauma.Chinese Clinical Trial Registry: ChiCTR-IPR-16009340.

Impact of Mechanism of Injury on Long-term Neurological Outcomes of Cervical Sensorimotor Complete Acute Traumatic Spinal Cord Injury.

Mechanism of injury is a largely understudied descriptor of acute traumatic spinal cord injury (tSCI). This study sought to compare the impact of high-energy and low-energy mechanisms of injury in neurological outcomes of cervical sensorimotor complete tSCI. Patients with tSCI were identified in 4 prospective, multicenter clinical trials and registries. American Spinal Injury Association Impairment Scale (AIS) grade was assessed ≤ 72 hours postinjury and followed up between 12 to 52 weeks. Patients were included if they had a cervical and sensorimotor complete (AIS-A) injury at baseline. Study outcomes were change in AIS grade and lower extremity motor, upper extremity motor, and total motor scores. Propensity score matching between high-energy mechanisms of injury (HEMI; e.g. , motor vehicle collisions) and low-energy mechanisms of injury (LEMI; e.g. , falls) groups was performed. Adjusted groups were compared with paired t-tests and McNemar test. Of 667 patients eligible for inclusion, 523 experienced HEMI (78.4%). HEMI patients were younger, had lower body mass index, more associated fractures or dislocations, and lower baseline lower extremity motor scores. After propensity score matching of these baseline variables, 118 pairs were matched. HEMI patients had a significantly worse motor recovery from baseline to follow-up based on their diminished change in upper extremity motor scores and total motor scores. Cervical sensorimotor complete tSCIs from HEMI were associated with significantly lower motor recovery compared to LEMI patients. Our findings suggest that mechanism of injury should be considered in modelling prognosis and in understanding the heterogeneity of outcomes after acute tSCI.

Risk factors for deep surgical site infection following surgically treated peri-ankle fractures: a case–control study based on propensity score matching

AimsThis study aims to identify the risk factors for deep surgical site infection (DSSI) following surgically treated peri-ankle fractures.MethodsWe performed a retrospective case–control study using the propensity score matching (PSM) method in 1:2 ratio, based on the 6 baseline variables, including age, gender, living area, insurance type, fracture location and surgical date. Data on patients who underwent surgical treatment of peri-ankle fractures were collected by inquiring their hospitalization medical records and operative records, as well as the laboratory reports. Conditional logistic regression analysis was performed to identify the risk factors for DSSI.ResultsA total of 2147 patients were eligibly included and 74 had a DSSI, indicating an incidence rate of 3.4%. After PSM, 70 cases of DSSI and 140 controls without DSSI were matched, constituting the study cohort. The univariate analyses showed significant differences between groups in terms of history of any surgery, time to operation, surgical wound classification, smoking, alcohol drinking, RBC count, hemoglobin concentration and hematocrit (%). The conditional logistic regression analysis showed time to operation of < 4 or > 9 (vs 4–9 days); unclean wound, current smoking, high-energy injury mechanism and lower hematocrit were independent risk factors for DSSI.ConclusionsTimely modification of smoking and hematocrit (%), and limiting operation within a rational time frame for an optimized soft tissue condition, may provide potential clinical benefits for SSI prevention.

Functional Outcomes of Primary Arthrodesis vs Open Reduction and Internal Fixation in the Treatment of Lisfranc Injuries

Category: Midfoot/Forefoot; Trauma Introduction/Purpose: The lack of data regarding functional outcomes of midfoot primary arthrodesis (PA) and open reduction and internal fixation (ORIF) contributes to significant debate regarding the optimal method of treatment for Lisfranc injuries. Although PA is associated with lower rates of secondary procedure and posttraumatic arthritis, its impact on foot functionality has come into question due to sacrifice of tarsometatarsal (TMT) mobility. The authors hypothesize that there is no significant difference between patient recorded outcome measures (PROMs) among patients receiving PA and ORIF for the treatment of Lisfranc injuries. Methods: A retrospective cohort study of patients surgically treated for Lisfranc injuries between January 2010 and January 2019 at a Level I trauma center was undertaken. Retrospective chart review was utilized to obtain patient demographics, comorbidities, procedural information, complications, and additional treatments. Responding by survey, patients reported their functional competency in performing daily and sports-related activities via the validated Foot and Ankle Ability Measure (FAAM) instrument. For each patient, scores for the Activities of Daily Living (ADL) and Sports sections were calculated. Patients also reported their perceived current level of function on a percent scale with respect to functionality prior to TMT injury. Results: Twenty-four patients underwent PA, and 27 patients underwent ORIF. There were no significant differences between age (P=0.55), incidence of high energy injury mechanisms (P=0.14), comorbidities, or time to surgical intervention from injury (P=0.25) among PA and ORIF groups. There were no significant differences in FAAM scores among PA and ORIF groups. The average ADL scores for PA (72.42 +- 17.53) and ORIF (68.11 +- 28.24) were not significantly different (P=0.52), nor were the average Sports scores for PA (47.92 +- 25.48) and ORIF (48.56 +- 29.44) groups (P=0.94). However, patients in the PA group reported a significantly higher level of perceived ADL function (77.96% +- 17.97%) compared to patients in the ORIF group (60.04% +- 35.47%, P=0.03); this was not the case for perceived Sports functionality (P=0.67). Conclusion: This analysis of PROMs revealed no significant difference in the ability to participate in ADLs and sports between PA and ORIF groups. These results align with our hypothesis and suggest that despite sacrificing TMT joint mobility, functional outcomes of patients receiving PA were not significantly different from those receiving ORIF for Lisfranc injuries.

Patients undergoing surgical treatment for low-energy distal radius fractures are more likely to receive a referral and participate in a fracture liaison service program.

Patients often do not receive osteoporosis screening after a low-energy distal radius fracture (DRF). The effect of osteoporosis on the healing of DRFs remains a debate, and it is unclear if surgical treatment of this injury affects the referral and participation rates in a fracture liaison service (FLS) program. The purpose of this study is to report on a large cohort of low-energy DRFs and identify demographic, clinical, and treatment factors that affect referral and participation rates in an FLS program. A retrospective review identified patients over 50years old who sustained a low-energy DRF between 2013 and 2018. Patients with high-energy or unknown injury mechanisms were excluded. The primary outcome was the effect of DRF surgical treatment on referral and participation rates in an FLS program. Secondary outcomes included patient demographic and clinical characteristic effects on referral and participation rates in an FLS program. In total, 950 patients met inclusion criteria. Two hundred thirty patients (24.2%) were referred and 149 (15.7%) participated in the FLS program. Patients who underwent surgery were more likely to be referred to the FLS (OR 1.893, CI 1.403-2.555, p < 0.001) and participate in the FLS program (OR 2.47, CI 1.723-3.542, p < 0.001) compared to patients who received non-operative treatment of their DRF. Patients who undergo surgical treatment of a low-energy DRF are more likely to be referred and participate in a FLS program. Further study is needed to identify why surgical treatment may affect referral and participation rates.

Can we predict size, Haraguchi type and preoperative displacement of posterior malleolar fractures in association with tibial shaft fractures?

To (1) determine if any injury characteristics or radiographic parameters of tibial shaft fractures (TSFs) could predict posterior malleolar fracture (PMF) size, and (2) identify characteristics of PMFs that were fixed versus those that were not in a cohort of ipsilateral TSFs that underwent intramedullary nailing. A cross-sectional radiographic study was performed at a single academic institution. Demographic and radiographic parameters of TSFs were recorded, including fracture obliquity angle (FOA) and distance from distal extent of fracture to plafond (DFP). Using CT, the PMFs were evaluated for Haraguchi classification, size measurements, and preoperative displacement. Multivariate regression analysis was used to identify independent predictors of PMF Harachuchi classification, size parameters, and preoperative displacement. Univariate differences between PMF that were fixed and not fixed were identified. 47 (50%) PMF underwent surgical fixation with 47 treated conservatively. There were no demographic differences between groups. Multivariate linear regression demonstrated increasing DFP and high energy injury mechanism as independent variables correlated with plafond surface area involvement, PMF height and width on sagittal CT cuts. Increasing DFP alone was correlated with PMF width on axial CT cuts and extent > 50% into incisura. Haraguchi type II fractures were associated with high energy injury mechanism (OR = 4.2 [95% CI = 1.3-14.5]; p = 0.02). Odds of Haraguchi type 3 fractures increased 9% per increased year of age (OR = 1.09 [95% CI = 1.04-1.16]; p = 0.006) and decreased 13% per 1% increase in relative DFP (OR = 0.87 [95% CI = 0.75-0.98]; p = 0.04). An increasing DFP of TSFs and high energy injury mechanism were independent predictors of PMF size, and high energy injury mechanism was also correlated with Haraguchi type II fracture patterns. Increasing age and decreasing DFP of TSFs predict Haraguchi type III PMF patterns. These radiographic parameters should prompt surgeons to plan for fixation in scenarios in which CT scan is not available. Diagnostic Level III.

Revisiting the epidemiology of mid shaft clavicle fracture-recent and emerging trends

&lt;p&gt;&lt;strong&gt;Background: &lt;/strong&gt;Clavicle fracture is a common injury involving upper limb. It accounts for 2.6-5% of injuries. Most common mechanism causing this injury is a fall on an outstretched hand. Clavicle fractures have a bimodal distribution with 1&lt;sup&gt;st&lt;/sup&gt; peak in young active adult males less than 30 years of age. Second peak in elderly females with osteoporotic bones. The annual incidence is highest in male under 20 age group, decreasing with subsequent age groups. Road traffic accidents is another mode of injury which is becoming increasingly common for mid shaft clavicle fractures.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods&lt;/strong&gt;: A prospective study was carried out over 12 months. A total of 126 patients met the inclusion criteria. The epidemiological data was collected at the time of presentation using standard case sheet proforma. Radiographic assessment was done for fracture classification.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results&lt;/strong&gt;: Mid Shaft clavicle fracture was most common in middle aged males (31-40 years) with right side being most commonly affected. Road traffic accidents was the most common cause of injury (62%). AO/OTA type 15B1 is the most common fracture morphology (45%). Most of the high energy road traffic accidents are associated with 15B3 type fractures while type 15B1 is more common in low energy mechanisms like ground level fall.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions: &lt;/strong&gt;Mid shaft clavicle fracture is a common injury in young population. It is increasingly being associated with road traffic accidents. The number of comminuted fractures, which represent high energy injury mechanism has been on the rise due to increase in high velocity accidents.&lt;strong&gt;&lt;/strong&gt;&lt;/p&gt;

Management of a rare case of isolated U-shaped displaced sacral fracture in a young female high school student

Sacral fractures in young healthy patients are usually linked to high-energy trauma. They are often associated with multiple other injuries. Isolated sacral fractures are rare and can be easily missed in the absence of other surrounding pelvic or spinal injuries. In this article, we present a rare case of isolated U-shaped displaced sacral fracture despite the high-energy mechanism of injury being missed on initial presentation. This is a 17-year-old healthy female who presented to the emergency department after falling from five-meter height. She complained of lower back pain and inability to ambulate. Physical examination revealed significant sacral tenderness, bilateral lower limb weakness and hypoesthesia, anesthesia of the saddle area, weak anal tone and absent anal reflex. Initial radiographs showed no apparent fractures. Further imaging by pelvic computed tomography, however, revealed an isolated U-shaped displaced sacral fracture. The patient was treated by decompression and lumbopelvic fixation by triangular osteosynthesis and iliosacral screw. This fixation method restored stability of the spinopelvic junction and allowed for early mobilization. At her 18-month follow-up visit, she showed minimal disability score (10%) on the Oswestry Disability Index. In conclusion, sacral fractures are considered exceedingly rare to occur in isolation and in young healthy patients.

Regional Anesthesia Decreases Inpatient But Not Outpatient Opioid Demand in Ankle and Distal Tibia Fracture Surgery.

Regional anesthesia (RA) is commonly used in ankle and distal tibia fracture surgery. However, the pragmatic effects of this treatment on inpatient and outpatient opioid demand are unclear. The hypothesis was that RA would decrease inpatient opioid consumption and have little effect on outpatient demand in patients undergoing ankle and distal tibia fracture surgery compared with patients not receiving RA. All patients aged 18 years and older undergoing ankle and distal tibia fracture surgery at a single institution between July 2013 and July 2018 were included in this study (n = 1310). Inpatient opioid consumption (0-72 hours postoperatively) and outpatient opioid prescribing (1 month preoperatively to 90 days postoperatively) were recorded in oxycodone 5-mg equivalents (OEs). Adjusted models were used to evaluate the impact of RA versus no RA on inpatient and outpatient opioid demand. Patients without RA had higher rates of high-energy mechanism of injury, additional injuries, open fractures, and additional surgery compared with patients with RA. Adjusted models demonstrated decreased inpatient opioid consumption in patients with RA (12.1 estimated OEs without RA vs 8.8 OEs with RA from 0 to 24 hours postoperatively, P < .001) but no significant difference after that time (9.7 vs 10.4 from 24 to 48 hours postoperatively, and 9.5 vs 8.5 from 48 to 72 hours postoperatively). Estimated cumulative outpatient opioid demand was significantly increased in patients receiving RA at all time points (112.5 OEs without RA vs 137.3 with RA from 1 month preoperatively to 2 weeks, 125.6 vs 155.5 OEs to 6 weeks, and 134.6 vs 163.3 OEs to 90 days, all P values for RA <.001). In ankle and distal tibia fracture surgery, RA was associated with decreased early inpatient opioid demand but significantly increased outpatient demand after adjusting for baseline patient and treatment characteristics. This study encourages the use of RA to decrease inpatient opioid use, although there was a worrisome increase in outpatient opioid demand. Level III: Retrospective, therapeutic cohort study.
