Two AIS Cases, 2 Surgeons, 1 Operating Room, 1 Day: Faster and Safer Than 1 Case in a Day.

BACKGROUND: To lessen surgical times for patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal instrumentation and fusion (PSIF), our department developed a quality improvement initiative where 2 AIS cases were completed in 1 day by the same 2 surgeons operating together in 1 operating room (OR). We describe the results of this initiative, comparing operative times and outcomes to cases of these surgeons operating individually. METHODS: From 2017 to 2023, patients aged 10 to 18 years with AIS undergoing PSIF were prospectively enrolled for "Two Spine Tuesday." Patients were matched by age, sex, curve severity, and number of levels fused to historical AIS controls. Outcomes included surgery time, total OR time, estimated blood loss (EBL), volume of cell saver transfused, allogenic blood transfusion, length of stay, 90-day readmissions, Clavien-Dindo-Sink Complication Classification System complication rates, and percentage who achieved the minimal clinically important difference (MCID) for SRS-22. RESULTS: Fifty-five patients composing the 2-spine group (group 2) were compared with 55 historical sex-matched and age-matched controls (group 1). Major coronal curve and average number of levels fused were similar between groups. Overall surgery time (203 vs. 296 min, P<0.001), total OR time (P<0.001), and EBL (400 vs. 550 mL, P<0.001) were lower for group 2. Group 2 had fewer complications [n=17 (31%) vs. n=28 (51%), P=0.03]. CONCLUSIONS: Performing 2 AIS cases in 1 OR by 2 surgeons the same day resulted in shorter surgery times, less total time in the operating room, lower complication rates, and less blood loss compared with single-surgeon matched controls. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

Technical Considerations and Avoiding Complications in Total Hip Arthroplasty.

Total hip arthroplasty (THA) is considered to be the surgical procedure of the 20th century. Current projections show that by 2030, primary THA is expected to grow by 171%, with revision THA expected to increase by 142% in the same time frame. Although complications are not common, when they occur, they can cause notable morbidity to the patient. Understanding the unique anatomy and needs of each patient will prepare the surgeon to avoid soft-tissue or bony injury, optimize prosthesis placement, and decrease the risk of infection. This article aims to highlight common causes of early revision THA and provide specific technical strategies to avoid these complications. Following a systematic approach to the primary THA and using these techniques will assist the surgeon in avoiding complications to revision hip arthroplasty.

Methamphetamine Intoxication and Perioperative Complications Following Orthopaedic Surgical Procedures.

Background Methamphetamine use is increasing in prevalence. There is a theoretical increased risk of complication postoperative due to catecholamine depletion. When presented with an urgent surgical problem, there are little data to help counsel the patient on the risks of undergoing surgery in the setting of a positive methamphetamine test result. Aims and objectives The aim of this study was to examine the perioperative complication rate for patients who underwent emergent orthopaedic procedures in the setting of a positive methamphetamine drug screen. Additional data were collected in an attempt to further stratify risk factors for perioperative complications in this patient population. Design and methods A retrospective case series of 110 patients. Patients were identified by querying the medical record for patients with a positive methamphetamine result within 24 hours of the surgery start time. Data were collected on each patient, including the nature of the surgery, the type of injury sustained, disposition from the operating room, among other data points. The primary outcome was the presence of a perioperative cardiopulmonary complication, as determined by a new diagnosis made in the chart. The secondary outcome was whether the patient needed an increased level of care postoperatively. Results Of the 110 charts reviewed, three patients sustained complications during their hospitalization; an overall complication rate of 2.7%. One patient developed acute respiratory distress syndrome (ARDS), while two others developed surgical site infections. Of the 19 patients who went to the intensive care unit (ICU) postoperatively, none were because the patient required a higher level of care than the preoperative level. Conclusions Patients who underwent emergent surgical intervention in the setting of a positive methamphetamine drug test had a low complication rate. While the dogma is to delay surgery in the setting of methamphetamine use, the true risk of undergoing surgery in this setting is not fully understood. We advocate for continued research in this poorly studied group of patients. Larger studies will need to be done in order to fully understand the risks associated with operating in the setting of a positive methamphetamine drug screen.

Anaphylaxis after injecting a hemostatic agent containing gelatin into vertebral bone under pressure-a warning.

STUDY DESIGN: Case series. PURPOSE: The use of topical hemostatic agents is common in spinal deformity surgery. While beneficial, emerging case data shows gelatin-containing agents causing intra-operative complications. We present two patients who developed anaphylaxis after injection of these gelatin-containing hemostatic agents into the vertebral body using manual pressure. In the literature, while anaphylactic reactions associated with the use of animal-derived gelatin has been implicated; the risk of injecting these products into the closed vascular cavity of the vertebral body with subsequent embolization into systemic circulation bears emphasis. This report is to meant to make the surgical team aware of the risks of injecting hemostatic agents using manual pressure into the vertebral body and to highlight a plausible mechanism for the phenomenon. METHODS: Two children with spinal deformity undergoing posterior spinal fusion procedures with the use of gelatin-containing hemostatic agents injected into the vertebral body through the pedicle are described. RESULTS: Both patients had gelatin-containing hemostatic agent solution injected under manual pressure through the vertebral pedicle to prevent excessive bleeding. Anaphylaxis occurred soon thereafter, resulting in emergent cessation of the surgery and initiation of medical resuscitation. In both cases, tryptase levels obtained just after the event were elevated. CONCLUSION: Patients with an allergy to or prior history of exposure to zoologic products undergoing spine surgery may be at risk of anaphylaxis if the gelatin-containing hemostatic agent is injected under manual pressure into the closed space of the vertebral body. This allows rapid entry into the venous circulation. We recommend that the surgeon perform a thorough history of a patient's allergies and use extreme caution when injecting these topical hemostatic products into the vertebral body. LEVEL OF EVIDENCE: IV.

The Role of the Fracture Liaison Service in Osteoporosis Care.

Osteoporosis is a disease classified by the alteration of bony microarchitecture predisposing a person to fragility fractures. This costs the US $19 billion per year and is expected to rise as our population ages. Only 20% of patients with fragility fractures receive treatment for osteoporosis. A Fracture Liaison Service is a cost-effective way to follow patients and improve appropriate work up and management from multiple medical disciplines.
