Metrics of OsteoChondral Allografts (MOCA) Group Consensus Statements on the Use of Viable Osteochondral Allograft.

Background: Osteochondral allograft (OCA) transplantation has evolved into a first-line treatment for large chondral and osteochondral defects, aided by advancements in storage protocols and a growing body of clinical evidence supporting successful clinical outcomes and long-term survivorship. Despite the body of literature supporting OCAs, there still remains controversy and debate in the surgical application of OCA, especially where high-level evidence is lacking.

Purpose: To develop consensus among an expert group with extensive clinical and scientific experience in OCA, addressing controversies in the treatment of chondral and osteochondral defects with OCA transplantation.

Trends of Femoral Neck Fracture Treatment Using Total Hip Arthroplasty: Reported From the American Joint Replacement Registry.

Introduction: Total hip arthroplasty (THA) rather than hemiarthroplasty for displaced femoral neck fracture (FNF) is often chosen for younger patients who are more active and/or have underlying hip osteoarthritis. However, instability remains the primary concern of doing THA. Dual mobility (DM) has been shown to decrease this risk through a larger effective head size and greater head-to-neck ratio compared with conventional THA.

Impact of corset bracing on 3D spine kinematics during ADL in children with Spondylolysis.

Spondylolysis is a stress fracture of the vertebral pars interarticularis that frequently affects adolescents involved in sports. Conservative bracing methods may assist the clinician in treating spondylolysis, though there is a need to further validate these techniques. The goal of this study was to evaluate differences in the 3D movements of the thoracic and lumbar spine before and after bracing.

Defining a Surgical Invasiveness Threshold for Increased Risk of a Major Complication Following Adult Spinal Deformity Surgery.

Study Design: Retrospective review.

Objectives: The aim of this study was to define a surgical invasiveness threshold that predicts major complications after adult spinal deformity (ASD) surgery; use this threshold to categorize patients into quartiles by invasiveness; and determine the odds of major complications by quartile.

Summary Of Background Data: Understanding the relationship between surgical invasiveness and major complications is important for estimating the likelihood of major complications after ASD surgery.

Physical Activity, Sleep, and Sedentary Behavior among Successful Long-Term Weight Loss Maintainers: Findings from a U.S. National Study.

Despite adults' desire to reduce body mass (weight) for numerous health benefits, few are able to successfully lose at least 5% of their starting weight. There is evidence on the independent associations of physical activity, sedentary behaviors, and sleep with weight loss; however, this study provided insight on the combined effects of these behaviors on long-term body weight loss success. Hence, the purpose of this cross-sectional study was to evaluate the joint relations of sleep, physical activity, and sedentary behaviors with successful long-term weight loss.

COVID-19 related employment change is associated with increased alcohol consumption during the pandemic.

Partial warfarin reversal prior to hip fracture surgical intervention in geriatric trauma patients effects on blood loss and transfusions.

Background: Warfarin reversal is typically sought prior to surgery for geriatric hip fractures; however, patients often proceed to surgery with partial warfarin reversal. The effect of partial reversal (defined as having an international normalized ratio [INR] > 1.5) remains unclear.

Risk factors for reoperation after lumbar total disc replacement at short-, mid-, and long-term follow-up.

Background Context: The reoperation rate following TDR (Total Disc replacement) has been established at short- and mid-term time points through the Food and Drug Administration Investigational Device Exemption (FDA IDE) trials. However, these trials include highly selected centers and surgeons with strict governance of indications. The utilization of TDR throughout the community needs further analysis.

Scoliosis Research Society survey: brace management in adolescent idiopathic scoliosis.

Purpose: While the Scoliosis Research Society (SRS) has established criteria for brace initiation in adolescent idiopathic scoliosis (AIS), there are no recommendations concerning other management issues. As the BrAIST study reinforced the utility of bracing, the SRS Non-Operative Management Committee decided to evaluate the consensus or discord in AIS brace management.

Methods: 1200 SRS members were sent an online survey in 2017, which included 21 items concerning demographics, bracing indications, management, and monitoring.

The current state of navigation in robotic spine surgery.

The advent and widespread adoption of pedicle screw instrumentation prompted the need for image guidance in spine surgery to improve accuracy and safety. Although the conventional method, fluoroscopy, is readily available and inexpensive, concerns regarding radiation exposure and the drive to provide better visual guidance spurred the development of computer-assisted navigation. Contemporaneously, a non-navigated robotic guidance platform was also introduced as a competing modality for pedicle screw placement.
