Ambulating Five Feet within 72 Hours after Hip Fracture Surgery Associated with Independent Ambulation


A retrospective study in the Journal of the AAOS Global Research & Reviews® investigated the association between ambulation distance in acute postoperative settings and ambulatory capacity three months postsurgery for hip fractures. A total of 170 patients aged ≥65 years were divided into two groups: early (ambulated five feet within 72 hours after surgery) and minimally ambulatory. Factors associated with ambulatory status included the ability to ambulate five feet in 72 hours, ambulatory distance at discharge, and time from presentation to surgery. Patients with femoral fractures were more likely to independently ambulate than those with pertrochanteric fractures.

Study: Does Cannabis Use Disorder Affect Opioid Usage and PROs after ACLR?


According to a study in Sports Health, there were no significant differences in terms of opioid use following ACL reconstruction (ACLR) between patients with and without cannabis use disorder (CUD). In total, 104 patients with CUD were matched with 104 without.  Patient-reported outcomes (PROs) and total opioid refills and days’ supply up to one-year postoperatively were retrospectively compared. The rate of opioid prescription was 82.7 percent and 83.7 percent in the CUD and control groups, respectively, and there were no differences in total days’ supply. Furthermore, no significant differences were observed regarding pain intensity, pain interference, or mobility improvements between groups.

Study: Higher MMA Emissions in ORs with Conventional Ventilation versus Laminar Airflow Systems


The Journal of Bone and Joint Surgery published a prospective study comparing methylmethacrylate (MMA) vapor levels emitted during mixing among cement-mixing systems in an OR with conventional ventilation (CV) and an OR with laminar airflow (LAF). Five different vacuum cement-mixing systems were used to mix the same cement type according to the manufacturer’s instructions. MMA vapor concentrations were measured during five mixing phases, with each system used randomly 10 times in each case. Emissions remained generally higher in the CV setting for every system and in nearly every phase.

Study Evaluates Complications after Bone Marrow Aspirate Harvest from the Calcaneus


A retrospective chart review in Foot & Ankle Orthopaedics evaluated the efficacy of harvesting bone marrow aspirate from calcaneus bone as a surgical augment for healing injured tissue. Patient satisfaction, pain level, fusion rates, and complications were reviewed in 45 patients. Thirty-two patients reported having no pain at the final follow-up, and the remaining patients reported having only minimal pain. There were no reported incidences of infections, wound complications, or nerve injuries. Ten patients experienced arthrodesis, which healed by the final follow-up.

Study: Pediatric Patients with Sickle Cell Disease at Increased Risk of Postoperative Complications


Pediatric patients with sickle cell disease had an increased risk of complications following orthopaedic surgery, a study in the Journal of Pediatric Orthopaedics reported. The retrospective review examined 92 patients. The main outcome was postoperative complications within 30 days of surgery requiring an emergency department (ED) visit or hospital admission. More than half (51 percent) of surgeries required a preoperative blood transfusion. Nineteen surgeries with postoperative complications required an ED visit or hospital readmission within 30 days of surgery. Patients with >4 ED visits in the past year had a 5.7-fold increased risk of a complication.
