Background: Given the lack of objective data on opioid use and the difficulty of addressing a patient's postoperative pain, we sought to quantify patient's narcotic use after hallux valgus surgery. The purpose of our study was to determine the average quantity and type of postoperative opioids consumed after hallux valgus surgery and to assess potential predictive factors for increased opioid consumption.

Methods: At the preoperative visit, patients were consented and completed a demographical questionnaire.

A 57-year-old female presented with L4-L5 and L5-S1 mobile spondylolisthesis and associated stenosis with radiculopathy who failed conservative treatment. This patient underwent lateral lumbar interbody fusion (LLIF) of L4-L5 and L5-S1, and posterior spinal fusion (PSF) with instrumentation. LLIF is a minimally invasive procedure to treat degenerative diseases of the lumbar spine.

Background: Annually there are an estimated 4.5 million sports- and recreation-related injuries among children and young adults in the United States. The most common sports-related injuries are to the lower extremities, with two-thirds occurring among children and young adults (age range 5-24 years).

Introduction: Chemical prophylaxis using low-molecular-weight heparin (LMWH) is considered a standard of care for venous thromboembolism in trauma patients. Our center performs a head computed tomography (CT) scan 24 hours after initiation with prophylactic LMWH in the setting of a known traumatic brain injury (TBI). The purpose was to determine the overall incidence of ICH progression after chemoprophylaxis in patients with a TBI.

Introduction: Hallux valgus is a commonly treated condition by foot and ankle surgeons with more than 200 different described correction techniques. Recurrence rates range from 5% to 50%, with increasing support of the theory that arthrodesis procedures may have a lower recurrence rate than osteotomies. Arthrodesis procedures to the first metatarsophalangeal (MTP) joint or tarsometatarsal (TMT) joint for correction of hallux valgus deformity are becoming more commonly utilized.

Purpose: The purpose of this study was to determine if the Single-Assessment Numeric Evaluation (SANE) score correlates with existing validated hip-specific patient-reported outcome measures (PROMs), including the Modified Harris Hip Score (mHHS), the International Hip Outcome Tool (IHOT-33), the Hip Outcome Score, Activities of Daily Living subscale (HOS-ADL), and the Hip Outcome Score, Sport-Specific subscale (HOS-SS), for patients preparing to undergo hip arthroscopy for treatment of femoroacetabular impingement syndrome (FAIS).

Methods: A single surgeon's operative database was retrospectively reviewed to identify patients undergoing primary hip arthroscopy for treatment of FAIS from April 2018 to October 2019. Patient-specific factors including age, sex, body mass index (BMI), and duration of symptoms were collected.

The purpose of this study was to determine if physical, mental health and patient-specific factors are associated with increased Pain Catastrophizing in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Patients who underwent primary hip arthroscopy for FAIS were retrospectively analyzed. Patients were included if they completed a standard pre-operative questionnaire which included the Pain Catastrophizing Scale (PCS), VAS and 12-Item Short Form Survey (SF-12) Physical and Mental Composite Scores.

Purpose: Elastic stable intramedullary nailing (ESIN) and open reduction internal fixation (ORIF) are literature-supported operative treatments for displaced tibial shaft fractures in skeletally immature patients. Very little is written about rigid intramedullary nails (RIMNs) in adolescents. Our purpose is to describe a physeal-sparing, reamed, locked RIMN technique for adolescent tibial shaft fractures and report its safety.

Background: The American Orthopaedic Association (AOA) released the standardized letter of recommendation (SLOR) form to provide standardized information to evaluators of orthopaedic residency applicants. The SLOR associates numerical data to an applicant's letter of recommendation. However, it remains unclear whether the new letter form effectively distinguishes among orthopaedic applicants, for whom letters are perceived to suffer from "grade inflation.

Purpose: To quantify the effect of the learning curve in performing hip arthroscopy for femoroacetabular impingement (FAI) and labral tears on total operating room time, including times for setup, surgery, and wake up, during a single surgeon's initial hip arthroscopy procedures.

Methods: A single surgeon's case list was retrospectively reviewed to identify all primary hip arthroscopy surgeries between November 1, 2018, and February 28, 2018, for the treatment of FAI and labral tears. Surgical times were recorded, including total room time; surgical time; setup time; and wake-up time.

Purpose: To evaluate the impact of the portal used for drilling, the position of the drill guide on the acetabular rim, and the use of straight versus curved drill guides on drill perforation of the acetabular subchondral bone and the outer cortex of the acetabulum.

Methods: Sixty acetabular models were marked at the 3-, 2-, 1-, 12-, and 11-o'clock positions. Simulated anterior, anterolateral, and distal anterolateral accessory (DALA) portals were created.
