Outcomes in Early Versus Delayed Management of Pediatric Femoral Shaft Fractures.

OBJECTIVE: There is a paucity of literature regarding the timing of treatment for pediatric femur fractures. The purpose of this study was to analyze whether early versus delayed management of pediatric femoral shaft fractures would impact outcomes regarding time to union and return to baseline function. METHODS: Pediatric patients presenting with femoral shaft fractures, from January 1, 2010 to January 1, 2021, were identified using the Pediatric Trauma Database at a single Level One Trauma Center and retrospectively reviewed. Demographic information, surgical details, associated injuries, length of follow-up, time to union, and return to baseline function were collected. Patients were then divided into 2 groups; the early intervention group underwent treatment within 24 hours of admission versus the delayed group, which underwent treatment after 24 hours. Patients with neuromuscular disease, pathologic fracture, slipped capital femoral epiphysis, nonambulatory, younger than 6 months old, or had follow-up of <8 weeks posttreatment were excluded. χ 2 and unpaired Student t tests were used to compare outcomes. A P value ≤0.05 was used as the threshold of statistical significance. RESULTS: Of the 169 cases reviewed, 137 met the inclusion criteria. The mean age was 8.0 ± 5.0 (6 mo to 16 y). The average follow-up time was 1.4 ± 1.4 years. Thirty-two (19%) patients did not meet the inclusion criteria and were excluded from the study. One hundred twenty-two (89%) patients were in the early intervention group versus 15 (11%) in the delayed intervention group. There were no statistically significant differences between the early and the delayed arms in regard to time to union, quality of final reduction, and return to baseline function. CONCLUSION: The findings of this study support that the timing of surgical intervention of femoral shaft fractures in the pediatric population is not correlated to time to union and final function. Clinically, prompt treatment of pediatric femoral shaft fractures should not supersede medical methods of resuscitation and likely has no bearing on the final outcome. LEVEL OF EVIDENCE: Level III.

Pilon fractures: Consensus and controversy.

Pilon fractures are complex injuries that require an individualized approach to treatment to avoid complications and achieve good outcomes. Staged open reduction internal fixation remains the gold standard for most cases to achieve anatomic articular reduction while minimizing soft tissue complications and infection. Careful preoperative planning based on computed tomography dictates the surgical approach for reduction. A subset of cases may be amenable to early definitive or provisional open reduction and internal fixation based on fracture pattern. In some cases of severe articular comminution where reconstruction is not possible, primary ankle arthrodesis may be a good alternative.

Evaluation of the Efficacy of an Online Learning Module to Increase Wound Care Theoretical Knowledge Amongst Medical Students.

OBJECTIVE: We developed and evaluated an online learning module for teaching wound care basics to junior medical learners, which was assessed for its ability to increase theoretical knowledge of wound care, and medical learners' perceptions on the use of an online module to teach wound care practices. DESIGN: Between February 2022 to November 2022, participants were enrolled into our unblinded, matched-pair single-arm study. Participants completed a pre- and postquiz prior to and after completing the online module, respectively. Scores on the pre- and postquiz were matched by participant and evaluated for improvement. The online module was composed of free text, animated videos with voiceovers, pictorial examples, and tables, as well as unscored knowledge checks, covering the categories of i) normal wound healing physiology, ii) describing wounds/assessment of wounds, iii) choosing dressings for wounds, and iv) addressing and understanding wound aetiologies, including diabetic, arterial, and venous ulcers. SETTING: Participants were enrolled at the University of Toronto in Toronto, Canada. PARTICIPANTS: Participants were recruited from the undergraduate medicine and physician assistant programs at the University of Toronto. Students were provided with information on how to participate in the study through email and in-person recruitment. Thirty-three participants entered the study, and 23 participants completed the study. RESULTS: Across all participants, the prequiz to postquiz score increase averaged 13.29%, representing a statistically significant increase (p = 0.0000013). Ten of the 20 questions and all question categories had a statistically significant increase in the postquiz scores. All respondents found the module very useful (67%) or extremely useful (33%) for learning wound care, and 67% were very satisfied overall with the quality of the module, with the remainder (33%) of respondents somewhat satisfied. CONCLUSIONS: Online learning modules are effective at increasing wound care knowledge in junior medical learners, with high satisfaction amongst learners.

A Patella-Sided Tensioning Technique for Medial Patellofemoral Ligament Reconstruction.

Reconstruction of the medial patellofemoral ligament (MPFL) is a common procedure for treatment of recurrent patellofemoral instability. Over the last two decades, multiple surgical techniques for MPFL reconstruction have been described with no clear consensus on a superior reconstruction technique. Appropriate graft tensioning is one of the most important factors for a successful MPFL reconstruction. Overtensioning of the MPFL graft can lead to patellofemoral joint overload and undertensioning can lead to recurrent instability. Current literature demonstrates descriptions of MPFL reconstruction with final graft tensioning performed off of the femoral side. We describe a technique in this article for performing final graft tensioning from the patellar side, which gives the surgeon an option for intraoperative tension adjustments after evaluating patellar tracking.

What is New in Pediatric Orthopaedic: Basic Science.

BACKGROUND: An understanding of musculoskeletal basic science underpins most advancements in the field of orthopaedic surgery. Knowledge of biomechanics, genetics, and molecular pathways is integral to the understanding of the pathophysiology of disease and guides novel treatment options to improve patient outcomes. The purpose of this review is to provide a comprehensive and current overview of musculoskeletal basic science relevant to pediatric orthopaedic surgery. METHODS: Comprehensive Pubmed database searches were performed for all English language articles published between January 2016 and November 2021 using the following search terms: basic science, pediatric orthopaedics, fracture, trauma, spine, scoliosis, DDH, hip dysplasia, Perthes, Legg-Calve-Perthes, clubfoot, and sports medicine. Inclusion criteria focused on basic science studies of pediatric orthopaedic conditions. Clinical studies or case reports were excluded. A total of 3855 articles were retrieved. After removing duplicates and those failing to meet our inclusion criteria, 49 articles were included in the final review. RESULTS: A total of 49 papers were selected for review based on the date of publication and updated findings. Findings are discussed in the subheadings below. Articles were then sorted into the following sub-disciplines of pediatric orthopaedics: spine, trauma, sports medicine, hip, and foot. CONCLUSIONS: With this review, we have identified many exciting developments in pediatric orthopaedic trauma, spine, hip, foot, and sports medicine that could potentially lead to changes in disease management and how we think of these processes. LEVEL OF EVIDENCE: Level V.

Basic Hip Arthroscopy: Diagnostic Hip Arthroscopy.

Hip arthroscopy is increasing in popularity for the diagnosis and management of hip preservation. The basics of hip arthroscopy positioning, fluoroscopic assessment, and portal establishment are reviewed in the first 2 parts of this series. This article is the third installment in which we describe a systematic approach to performing a diagnostic hip arthroscopy. A mastery of diagnostic arthroscopy is necessary for surgeons treating hip disorders.

Basic Hip Arthroscopy: Anatomic Establishment of Arthroscopic Portals Without Fluoroscopic Guidance.

Hip arthroscopy has gained popularity in recent years for diagnostic and therapeutic hip preservation management. This article details the establishment of arthroscopic portals of the hip, specifically the anterolateral and modified anterior portals without fluoroscopic guidance. The anterolateral portal is established anatomically, and the modified anterior portal is then established under arthroscopic guidance. A through understanding of the hip anatomy allows for these portals to be made both safely and reliably for hip arthroscopies in the modified supine positioned patient. The reduced use of fluoroscopy with this technique lowers the risk of ionizing radiation exposure to the patient and surgeon.

Anatomic and physiopathologic changes affecting the airway of the elderly patient: implications for geriatric-focused airway management.

There are many anatomical, physiopathological, and cognitive changes that occur in the elderly that affect different components of airway management: intubation, ventilation, oxygenation, and risk of aspiration. Anatomical changes occur in different areas of the airway from the oral cavity to the larynx. Common changes to the airway include tooth decay, oropharyngeal tumors, and significant decreases in neck range of motion. These changes may make intubation challenging by making it difficult to visualize the vocal cords and/or place the endotracheal tube. Also, some of these changes, including but not limited to, atrophy of the muscles around the lips and an edentulous mouth, affect bag mask ventilation due to a difficult face-mask seal. Physiopathologic changes may impact airway management as well. Common pulmonary issues in the elderly (eg, obstructive sleep apnea and COPD) increase the risk of an oxygen desaturation event, while gastrointestinal issues (eg, achalasia and gastroesophageal reflux disease) increase the risk of aspiration. Finally, cognitive changes (eg, dementia) not often seen as related to airway management may affect patient cooperation, especially if an awake intubation is required. Overall, degradation of the airway along with other physiopathologic and cognitive changes makes the elderly population more prone to complications related to airway management. When deciding which airway devices and techniques to use for intubation, the clinician should also consider the difficulty associated with ventilating the patient, the patient's risk of oxygen desaturation, and/or aspiration. For patients who may be difficult to bag mask ventilate or who have a risk of aspiration, a specialized supralaryngeal device may be preferable over bag mask for ventilation. Patients with tumors or decreased neck range of motion may require a device with more finesse and maneuverability, such as a flexible fiberoptic broncho-scope. Overall, geriatric-focused airway management is necessary to decrease complications in this patient population.
