The Application of Hyaluronic Acid/Alginate Sheet to Flexor Pollicis Longus Tendon Repair to Prevent Adhesion Formation: A Second Look.

Soft tissue traumas with tendon lacerations are challenging injuries to manage. Repair of these tendon injuries can be complicated by adhesions postoperatively, limiting patient function and satisfaction. Biologic agents have been developed to optimize tendon gliding after repair and can be used as adjuncts.

Comparison of osteotomy level with three different canine total hip replacement systems.

Background: Numerous cementless total hip replacement (THR) systems are available for application in dogs and one of the potential differences among these systems is the technique for performing a femoral osteotomy and the amount of bone preserved in the calcar region. However, no quantitative comparison of osteotomy level has been performed for canine THRs to date.

Aims: To develop and validate a method for quantifying the level of the osteotomy at its most distomedial aspect in conjunction with canine THR and to compare osteotomy level between multiple different THRs.

Risk of shortening in operatively treated proximal femur fractures with cephalomedullary nails with dynamically versus statistically locked helical blades.

Introduction: Cephalomedullary nails (CMN) have proven to be effective for the fixation of unstable pertrochanteric hip fractures, but limited data exists regarding the degree of shortening that occurs with nailing systems that offer "dynamically" versus "statistically" locked helical blades. This study aimed to determine the incidence, timing, and amount of postoperative fracture shortening in patients with pertrochanteric hip fractures treated with "dynamically" versus "statistically" locked helical blades.

Methods: A retrospective review was performed on patients requiring operative fixation of pertrochanteric fractures.

Physeal fusion status and lesion size are more important than patient age for healing of juvenile osteochodritis dessicans lesions of the distal femur.

Purpose: The purpose of the study was to evaluate the effect of skeletal age and lesion size, location, and grade on the success of nonoperative treatment for juvenile osteochondritis dissecans (OCD). It is hypothesized that skeletal maturity, including a combination of maturation phenotypes, correlates with nonoperative lesion healing.

Methods: The clinical and radiographic data on 52 patients aged 7-20 years treated for OCD of the distal femur between 2010 and 2019 were retrospectively reviewed.

Older adults who resistance train improve physical function and adopt long-term exercise habits despite COVID-19 restrictions.

Exercise interventions targeting older adults often focus on acute changes, but lasting improvements require the adoption of long-term, independent exercise habits. This study aimed to assess the influence of eight-weeks of resistance training (SSSH) on clinically relevant fall-risk indicators in older adults and to evaluate if SSSH participation altered independent exercise engagement 12 months later. Sixty adults aged 50 yrs+ were randomised into SSSH, Walk, or Control groups and completed questionnaires and muscle strength and flexibility tests pre/post 8 weeks.

Overall Safety and Risks Associated with Blood Flow Restriction Therapy: A Literature Review.

Introduction: Blood flow restriction therapy (BFRT) is used in scenarios ranging from muscle building in athletic performance to decreasing recovery time in postoperative orthopedic rehabilitation. The efficacy of BFRT for treating diseases has been increasingly researched; however, there has been less literature focused on establishing the safety of this therapy.

Materials And Methods: An extensive literature review pertaining to BFRT and any deleterious events related to its usage was completed by searching multiple databases, including PubMed, EMBASE, and Cochrane Library using the terms "blood flow restriction therapy" or "KAATSU.

Use of small animal PET-CT imaging for assessment of tendon-to-bone healing: A pilot study.

Background: The availability of non-invasive means to evaluate and monitor tendon-bone healing processes is limited. Micro Positron-Emission-Tomography (µPET) using F-Fluoride is a minimally invasive imaging modality, with which osteoblast activity and bone turnover can be assessed. The aim of this study was to investigate the use of serial µPET/CT scans to evaluate bone turnover along the graft-tunnel interface in a rat ACL (anterior cruciate ligament) reconstruction model.

Lower extremity injuries in the baseball athlete.

Baseball is unique in its multiple facets: pitching, hitting, base rounding, and fielding are distinct activities that require different athletic skills to perform at a high level. Likewise, these different aspects of the game can contribute to a multitude of varying injuries. While high-velocity overhead throwing, along with batting, can produce a plethora of upper extremity injuries that often garner attention, injuries to the lower extremity can severely impact a player's performance and ability to compete.

Utility of lateral scapular radiographs in initial evaluation of nontraumatic shoulder conditions.

Background: Lateral scapular radiographs have been routinely included in the initial radiographic examination of both traumatic and nontraumatic shoulder conditions. With the advance of modern imaging modalities, the clinical utility of the lateral scapular view has become questionable. The purpose of the study was to assess the utilization of the lateral scapular view among the members of the American Shoulder and Elbow Surgeons (ASES) and to determine the clinical utility of the lateral scapular view in the initial evaluation of nontraumatic shoulder conditions.

Bracing for the Patellofemoral Joint.

Patellofemoral disorders are common causes of knee pain that result in frequent visitations to musculoskeletal care clinics. Patellar tendinopathy, patellar instability and patellar maltracking, and pain are some of the most common pathologies resulting in patellofemoral dysfunction. For each of these diagnoses, there are unique orthoses and braces available, some of which are uniquely designed to address the pathology involved.

The Role of Bracing in ACL Injuries: The Current Evidentiary State of Play.

Anterior cruciate ligament (ACL) injuries and surgeries are both increasing in incidence. A notable rate of reinjury and failure does occur after ACL surgery. As a result, interventions that may reduce ACL injury or reinjury are needed and are active areas of innovation.

The More the Merrier: Integrating Multiple Models of Skeletal Maturity Improves the Accuracy of Growth Prediction.

Background: Multiple systems using radiographic skeletal markers to measure development have been described, including the Greulich and Pyle Atlas (GP), the Fels Method (Fels), and the Sanders Hand Classification (Sanders). The purpose of this study was to quantitatively assess whether the integration of skeletal maturity assessment methods and demographic variables improves the accuracy of pediatric growth predictions over the use of skeletal markers or chronologic age alone.

Methods: The Brush Inquiry contains prospectively collected longitudinal data on children who lived in Cleveland, Ohio between 1926 and 1942.

Initial Validation of a Modified MRI Scoring System for Assessing Outcomes after Single-Surface Osteochondral Shell Allograft Transplantation in the Knee.

The Osteochondral Allograft Magnetic Resonance Imaging Scoring System (OCAMRISS) provides a reproducible method for imaging-based grading for osteochondral allograft (OCA) transplants. However, the OCAMRISS does not account for larger whole-surface OCA shell grafts, and has not been validated for assessing outcomes after shell OCA transplantation. Therefore, the objective of this study was to evaluate a modified OCAMRISS for assessing single-surface shell OCAs in the knee based on strength of correlations for a modified OCAMRISS score with graft success and patient-reported outcomes for pain and function.
