RESUMO
OBJECTIVE: Two wheel motorized vehicles used in both street transportation and recreation are a common cause of severe injury in the United States (US). To date, there has been limited data describing the spinal injury patterns among these motorcycle injury patients in the US. The goal of this study is to characterize and compare differences in specific injury patterns of patients sustaining traumatic spinal injuries after motocross (off-road) and street bike (on-road) collisions in the southwestern US at a Level I Trauma Center. METHODS: Trauma registry data was queried for patients sustaining a spinal injury after motorcycle collision from 2010 to 2019 at a single Level I Trauma Center. Computed tomography (CT) scan and magnetic imaging resonance imaging (MRI) reports from initial trauma evaluation were reviewed and data was manually obtained regarding injury morphology and location. RESULTS: A total of 1798 injuries were identified in 549 patients who sustained a motorcycle collision, specifically 67 off-road and 482 on-road motorcycle patients. Off-road motorcycle patients were found to be significantly younger (34.75 vs. 42.66, p = 0.00015). A total of 46.2% of the off-road injuries were determined to be from compression mechanisms, compared to 32.9% in the on-road cohort (p = 0.0027). The on-road cohort was more likely to have an injury classified as insignificant, such as transverse and spinous process fractures (60.1% vs. 42.5%, p = 00.25). There was no significant difference in regards to junctional, mobile, and semirigid spine segments between the two cohorts. CONCLUSIONS: Different fracture patterns were seen between the off-road and on-road motorcycle cohorts. Off road motorcyclists experienced significantly more compression and translational injuries, while on road motorcyclists experienced more frequent insignificant injury patterns. Data on the different fracture patterns may help professionals develop safety equipment for motorcyclists.

BACKGROUND: There is a paucity of research investigating the harms associated with orthopaedic knee scooter (OKS) use and patient safety perceptions. This prospective study aimed to define the prevalence of OKS-related injuries, describe the patient perceptions of OKS safety, and identify potential risk factors. METHODS: This study was conducted at a single foot and ankle fellowship-trained surgeon's community-based clinic from 6/2020 to 4/2021 and enrolled 134 patients. Our primary outcome was an OKS-related event (injury or fall) and informed an a priori power analysis. Point estimate of association magnitude was calculated as an odds ratio (OR) for statistically and clinically significant associations. RESULTS: There were 118 (88%) patients eligible for analysis; fourteen enrolled patients did not use OKS, and two withdrew. The prevalence of patient falls was 37% (44/118), and the prevalence of patient injury was 15% (18/118). Four percent of patients would not recommend OKS and 8% would not use an OKS again. Sedentary lifestyle increased risk (OR = 4.67, 1.52-14.35 95 CI) for OKS-related injury. CONCLUSIONS: Despite a high prevalence of patient falls (37%), there is a low prevalence of injury (15%) and a favorable perception of OKS safety. Sedentary lifestyles may be a risk factor for OKS-related injury and should be considered in the development of a risk model.

OBJECTIVES: Ultrasound-guided injections are used to treat common shoulder pathologies and have been shown to be more accurate and effective than traditional landmark-guided procedures. Currently, there exists no inexpensive shoulder model that accurately simulates the anatomical structures of the shoulder while also facilitating glenohumeral joint (GHJ) injection. Our model is an alternative to the traditional bedside training and provides a low-risk training environment. METHODS: We created this model from easily accessible materials. Polyvinyl chloride pipe was used to create the skeletal infrastructure pectoral girdle. A detergent pod was used to represent the GHJ space. Steaks were used to simulate the infraspinatus and deltoid muscles, with meat glue as a fascial layer between the two simulated muscles. Total cost of materials for the model was $19.71. RESULTS: Our model successfully replicates known anatomical features of the GHJ. Additionally, the model facilitates injection into a GHJ space, representing a GHJ injection. Our model was replicated to train medical student practitioners during five different educational sessions. The model was validated through comparison to standardized educational ultrasound training videos. It was further validated by ultrasound experts. CONCLUSIONS: The shoulder model we created is effective in simulating GHJ injections under ultrasound guidance. It simulates realistic muscle and bony landmarks both for ultrasound imaging and injection feel. Importantly, it is inexpensive and easy to replicate allowing more access to medical practitioners and students to be educated on the procedure.

Introduction: Arthrodesis remains the gold standard for most first metatarsal-phalangeal joint (1MTPJ) pathologic conditions due to its high patient satisfaction, low complication rates, and consistent data. 1MTPJ arthroplasty remains a pursued procedure given the advantages described above, but the literature remains complicated and controversial as a primary surgical treatment. To the authors' knowledge, there is no prior report describing utilization of arthroplasty as an approach to managing clinical failure of a successful fusion in the setting of a technically successful procedure without a post-operative complication. Case Report: We present a case report of a 70-year-old female patient who underwent a successful 1MTPJ arthrodesis for hallux valgus and hallux rigidus and extensive tarsometatarsal arthrodesis for midfoot arthritis. Although the patient had radiographic evidence of successful fusion and had no surgical complications, she presented with dissatisfaction and pain due to functional limitations imposed by the procedure sequelae. The patient was diagnosed with right foot hallux interphalangeus with painful retained hardware. Conservative management failed to improve dissatisfaction or symptoms, and the patient opted for surgical takedown of her fusion with conversion to metatarsal-phalangeal joint arthroplasty, removal of hardware, and second toe proximal phalanx exostectomy. A stepwise surgical technique is described for the procedure, which was successful in addressing the patient's perceived clinical failure. Conclusion: Our case report describes a rare example of a patient who did not tolerate successful arthrodesis of the 1MTPJ, which was successfully revised to recreate the joint using a decellularized dermal allograft. The procedure resulted in fantastic patient satisfaction and long-term outcomes. This case report highlights a potential salvage option for patients who do not tolerate a 1MTPJ arthrodesis.
RESUMO
BACKGROUND: What level I evidence exists to support the use of FNF for surgical management of ankle fractures in high risk patients? The purpose of this study was to compare clinical outcomes following fibular intramedullary nail fixation (FNF) and open reduction and internal fixation (ORIF) of ankle fractures. METHODS: A systematic review of the current literature was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Certainty of evidence reported according to GRADE (Grading of Recommendations Assessment, Development, and Evaluation). Our primary hypothesis was that patients undergoing FNF procedures to manage an ankle fracture would have significantly higher patient reported outcome scores (PROs) than patients undergoing ORIF. Primary study outcome measures were validated PROs. Secondary outcome measures included complication rate, secondary surgery rate, and bony union. RESULTS: The primary outcome analysis revealed no evidence of a significant effect difference on Olerud and Molander Ankle Score (OMAS) PRO and no evidence of statistical heterogeneity. Secondary outcome analysis revealed a significant 0.30 (0.12-0.74 95CI) relative risk reduction for complications in FNF (P = 0.008). No evidence of an effect difference for bony union. The GRADE certainty of the evidence was rated as low for bone union. No evidence of reporting bias was appreciated. Sensitivity analyses did not significantly alter effect estimates. CONCLUSION: This systematic review and meta-analysis restricted to evidence derived from RCTs revealed that the quality of evidence is reasonably strong and likely sufficient to conclude: (1) there is likely no clinically important difference between FNF and ORIF up to 12 months post-operatively, as defined by OMS (moderate certainty); (2) surgeons may reasonably expect reduced complications in 14 out of every 100 patients treated with FNF (moderate certainty); (3) there is likely no difference in bony union (low certainty). Future studies should investigate more patient-centered outcomes and if short-term findings are durable over time if these findings apply to lower risk populations. LEVEL OF EVIDENCE: Systematic review and meta-analysis of level I evidence.
