Medically Necessary Orthopaedic Surgery During the COVID-19 Pandemic: Safe Surgical Practices and a Classification to Guide Treatment.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has rapidly evolved as a viral pandemic. Countries worldwide have been affected by the recent outbreak caused by the SARS (severe acute respiratory syndrome)-CoV-2 virus. As with prior viral pandemics, health-care workers are at increased risk. Orthopaedic surgical procedures are common in health-care systems, ranging from emergency to elective procedures. Many orthopaedic surgical procedures are life or limb-saving and cannot be postponed during the COVID-19 pandemic because of potential patient harm. Our goal is to analyze how orthopaedic surgeons can perform medically necessary procedures during the pandemic and to help guide decision-making perioperatively. METHODS: We performed a review of the existing literature regarding COVID-19 and prior viral outbreaks to help guide clinical practice in terms of how to safely perform medically necessary orthopaedic procedures during the pandemic for both asymptomatic patients and high-risk (e.g., COVID-19-positive) patients. We created a classification system based on COVID-19 positivity, patient health status, and COVID-19 prevalence to help guide perioperative decision-making. RESULTS: We advocate that only urgent and emergency surgical procedures be performed. By following recommendations from the American College of Surgeons, the Centers for Disease Control and Prevention, and the recent literature, safe orthopaedic surgery and perioperative care can be performed. Screening measures are needed for patients and perioperative teams. Surgeons and perioperative teams at risk for contracting COVID-19 should use appropriate personal protective equipment (PPE), including N95 respirators or powered air-purifying respirators (PAPRs), when risk of viral spread is high. When preparing for medically necessary orthopaedic procedures during the pandemic, our classification system will help to guide decision-making. A multidisciplinary care plan is needed to ensure patient safety with medically necessary orthopaedic procedures during the COVID-19 pandemic. CONCLUSIONS: Orthopaedic surgery during the COVID-19 pandemic can be performed safely when medically necessary but should be rare for COVID-19-positive or high-risk patients. Appropriate screening, PPE use, and multidisciplinary care will allow for safe medically necessary orthopaedic surgery to continue during the COVID-19 pandemic. LEVEL OF EVIDENCE: Prognostic Level V.

Intramedullary nailing of subtrochanteric fractures--does malreduction matter?

INTRODUCTION: Subtrochanteric femur fractures remain challenging injuries to treat. Historically, varus malreduction has been linked to the development of nonunion; however, there is a paucity of literature evaluating the impact of sagittal plane malreduction. The purpose of this study was to evaluate the influence of coronal and sagittal plane malreductions on time to union of subtrochanteric femur fractures treated with an intramedullary device. METHODS: A retrospective study was performed of all sub-trochanteric fractures (AO/OTA type 32) treated at a single institution. Inclusion criteria consisted of: 1. 18 or more years of age, and 2. fracture stabilization using an intramedullary device. All patients included were followed to union or revision surgery. Radiographic evidence of healing was defined as bridging callus on three of four cortices on AP and lateral views. Delayed union was defined as lack of radiographic healing by 4 months postoperatively and nonunion as lack of healing by 6 months. The definition of malreduction was coronal or sagittal plane deformity greater than 10° at the fracture site. RESULTS: Thirty-five patients met inclusion criteria; 20 men and 15 women with an average age of 55 years (range 19 to 100 years). Mean clinical follow up was 7 months (range 3 to 18 months). Thirty-four of 35 fractures (97%) healed without need for additional surgery. Twenty-one of the 35 fractures (60%) healed within 4 months of surgery. Thirteen fractures (37%) had delayed union, and 1 (2.9%) developed nonunion requiring reoperation. Seven of 35 fractures (20.0%) had a malreduction of greater than 10°, defined as varus (2 fractures), flexion (4 fractures), or both (1 fracture). Of the seven fractures with a malreduction, all (100%) developed a delayed (6) or nonunion (1). Of the 28 fractures without malreduction, 21 (75%) healed within 4 months, 7 (25%) had a delayed union, and none had a nonunion. The presence of a malreduction greater than 10° in any plane resulted in a significantly higher rate of delayed or nonunion (p = 0.0005). CONCLUSION: For patients with subtrochanteric fractures treated with an intramedullary device, malreduction in any plane of greater than 10° resulted in a significantly increased rate of delayed or nonunion or both.

Minimally displaced clavicle fracture after high-energy injury: are they likely to displace?

BACKGROUND: Nondisplaced or minimally displaced clavicle fractures are often considered to be benign injuries. These fractures in the trauma patient population, however, may deserve closer follow-up than their low-energy counterparts. We sought to determine the initial assessment performed on these patients and the rate of subsequent fracture displacement in patients sustaining high-energy trauma when a supine chest radiograph on initial trauma survey revealed a well-aligned clavicle fracture. METHODS: We retrospectively reviewed the cases of trauma alert patients who sustained a midshaft clavicle fracture (AO/OTA type 15-B) with less than 100% displacement treated at a single level 1 trauma centre between 2005 and 2010. We compared fracture displacement on initial supine chest radiographs and follow-up radiographs. Orthopedic consultation and the type of imaging studies obtained were also recorded. RESULTS: Ninety-five patients with clavicle fractures met the inclusion criteria. On follow-up, 57 (60.0%) had displacement of 100% or more of the shaft width. Most patients (63.2%) in our study had an orthopedic consultation during their hospital admission, and 27.4% had clavicle radiographs taken on the day of admission. CONCLUSION: Clavicle fractures in patients with a high-energy mechanism of injury are prone to fracture displacement, even when initial supine chest radiographs show nondisplacement. We recommend clavicle films as part of the initial evaluation for all patients with clavicle fractures and early follow-up within the first 2 weeks of injury.

CONTEXTE: Les fractures de la clavicule accompagnées d'un déplacement minime voire nul sont souvent considérées comme des blessures mineures. Toutefois, ces fractures méritent probablement un suivi plus étroit chez le patient polytraumatisé que chez le patient dont la blessure résulte d'un impact à faible énergie. Nous avons voulu analyser l'évaluation initiale de ces patients et le degré de déplacement subséquent des fractures chez les victimes d'un traumatisme à forte énergie dont la première radiographie du thorax en position couchée a initialement révélé une fracture de la clavicule présentant un bon alignement. MÉTHODES: Nous avons passé en revue de façon rétrospective les dossiers de patients polytraumatisés ayant fait l'objet d'une alerte, atteints d'une fracture de la clavicule (type 15-B selon la classification AO/OTA) accompagnée d'un déplacement inférieur à 100 % et traités dans un seul centre de traumatologie de niveau 1 entre 2005 et 2010. Nous avons comparé le déplacement des fractures entre les radiographies thoraciques initiales en position couchée et les radiographies de suivi. Les consultations en orthopédie et les types d'épreuves d'imagerie ont aussi été consignés. RÉSULTATS: Quatre-vingt-quinze patients atteints d'une fracture de la clavicule répondaient aux critères d'inclusion. Au moment du suivi, 57 (60 %) présentaient un déplacement de 100 % ou plus du corps de la clavicule. La plupart des patients (63 %) de notre étude ont eu une consultation en orthopédie au cours de leur hospitalisation et 27 % avaient subi une radiographie de la clavicule le jour de leur admission. CONCLUSION: Les fractures de la clavicule chez des patients victimes d'un traumatisme à forte énergie sont sujettes au déplacement, et ce, même si les radiographies thoraciques initiales en position couchée ne montrent aucun déplacement. Nous recommandons la prise de clichés de la clavicule dans le cadre de l'évaluation initiale de tous les patients victimes d'une fracture de la clavicule et un suivi rapproché dans les 2 premières semaines suivant la fracture.
