The diagnostic performance of MRI signs to distinguish Pectoralis major tendon avulsions from Myotendinous injuries.

Skeletal Radiol 2021 May 12. Epub 2021 May 12.

All Pro Orthopedic Imaging Consultants, LLC, St. Louis, MO, USA.

Background: Management of pectoralis major (PM) injuries is largely determined by the anatomic location of the injury, with tendon avulsions from the humerus requiring surgery while myotendinous (MT) injuries are typically managed non-operatively. Because physical examination cannot reliably make this distinction, MRI is often used for staging. However, correct classification can also be difficult with MRI where there is extensive soft tissue edema and distorted anatomy. Read More

Medial Meniscal Ramp Lesion Repair Through Anterior Portals Using a Medial Collateral Ligament Pie-Crusting Technique.

Arthrosc Tech 2021 Apr 12;10(4):e1073-e1077. Epub 2021 Mar 12.

Department of Orthopedic Surgery, Seoul St. Mary's Hospital, College of Medicine, The Catholic University of Korea, Seoul, Republic of Korea.

Ramp injury, that is, injury to the peripheral attachment of the posterior horn of the medial meniscus, often requires additional surgery during anterior cruciate ligament (ACL) reconstruction. Diagnosis and treatment of ramp lesions are important because unrepaired ramp lesions could cause risk to the reconstructed ACL because of anteroposterior and external rotation laxity, whereas acute rupture or chronic deficiency of the ACL could also cause ramp lesions because of instability. Ramp lesions are difficult to diagnose and treat from the anterior compartment during arthroscopy. Read More

Medial Patellofemoral Ligament Reconstruction and Lateral Retinacular Lengthening from a Lateral Approach.

Arthrosc Tech 2021 Apr 8;10(4):e987-e994. Epub 2021 Mar 8.

University of Connecticut Health and School of Medicine, Department of Orthopedic Surgery, Farmington, Connecticut, U.S.A.

The medial patellofemoral ligament (MPFL) is frequently torn and attenuated in patients with acute or chronic patellar instability. The mainstay for surgical treatment has become MPFL reconstruction to reestablish the checkrein to lateral patellar translation. The authors describe a technique for MPFL reconstruction with concomitant lateral retinacular lengthening with a gracilis allograft and adjustable loop cortical femoral fixation performed chiefly from a lateral parapatellar approach.

An In Vitro Study Measuring the Effects of Circumferential and Near-Circumferential Closed Incisional Negative Pressure Wound Therapy Dressings.

Cureus 2021 Apr 9;13(4):e14389. Epub 2021 Apr 9.

Orthopedic Surgery, Queen's Medical Center, Honolulu, USA.

Background Negative pressure wound therapy (NPWT) and closed incisional negative pressure wound therapy (ciNPWT) have been shown to promote the healing of acute and chronic wounds. Despite the growth in their usage, the mechanism by which they promote healing is not fully understood. Several studies have shown that NPWT results in a combination of microdeformation and macrodeformation, which may promote wound recovery. Read More

Comparing orthopaedic paediatric trauma in a rural district general hospital and an urban major trauma centre: A retrospective cohort study.

Ann Med Surg (Lond) 2021 May 13;65:102276. Epub 2021 Apr 13.

Trauma and Orthopaedics Department, Raigmore Hospital, Old Perth Road, Inverness, Scotland, IV2 3UJ, United Kingdom.

Background: Studies from countries such as Australia and South Africa have demonstrated a difference in the types of injury managed in rural hospitals compared to larger, urban hospitals and so conclude staff require a different skill-set to work in these environments. There is some evidence this attitude may be prevalent amongst UK surgical trainees, resulting in difficulty recruiting to rural settings. In addition, studies have compared mortality in paediatric trauma patients in rural and urban hospitals, but none have described types of injury or orthopaedic operations required. Read More

Discriminative Validity of Vestibular Ocular Motor Screening in Identifying Concussion Among Collegiate Athletes: A National Collegiate Athletic Association-Department of Defense Concussion Assessment, Research, and Education Consortium Study.

Am J Sports Med 2021 May 12:3635465211012359. Epub 2021 May 12.

Department of Orthopedic Surgery, UPMC Sports Medicine Concussion Program, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania, USA.

Background: Vestibular and ocular motor screening tools, such as the Vestibular/Ocular Motor Screening (VOMS), are recognized as important components of a multifaceted evaluation of sport-related concussion. Previous research has supported the predictive utility of the VOMS in identifying concussion, but researchers have yet to examine the predictive utility of the VOMS among collegiate athletes in the first few days after injury.

Purpose: To determine the discriminative validity of individual VOMS item scores and an overall VOMS score for identifying collegiate athletes with an acute sport-related concussion (≤72 hours) from healthy controls matched by age, sex, and concussion history. Read More

Kinetic degradation and biocompatibility evaluation of polycaprolactone-based biologics delivery matrices for regenerative engineering of the rotator cuff.

J Biomed Mater Res A 2021 May 11. Epub 2021 May 11.

Connecticut Convergence Institute for Translation in Regenerative Engineering, UConn Health, Farmington, Connecticut, USA.

Whereas synthetic biodegradable polymers have been successfully applied for the delivery of biologics in other tissues, the anatomical complexity, poor blood supply, and reduced clearance of degradation byproducts in the rotator cuff create unique design challenges for implantable biomaterials. Here, we investigated lower molecular weight poly-lactic acid co-epsilon-caprolactone (PLA-CL) formulations with varying molecular weight and film casting concentrations as potential matrices for the therapeutic delivery of biologics in the rotator cuff. Matrices were fabricated with target footprint dimensions to facilitate controlled and protected release of model biologic (Bovine Serum Albumin), and anatomically-unhindered implantation under the acromion in a rodent model of acute rotator cuff repair.

The dynamics of human bone marrow adipose tissue in response to feeding and fasting.

JCI Insight 2021 May 11. Epub 2021 May 11.

Neuroendocrine Unit, Massachusetts General Hospital, Boston, United States of America.

Adipocytes were long considered to be inert components of the bone marrow niche, but both mouse and human models suggest that bone marrow adipose tissue (BMAT) is dynamic and responsive to hormonal and nutrient cues. In this study of healthy volunteers, we investigated how BMAT responds to acute nutrient changes, including analyses of endocrine determinants and paracrine factors from marrow aspirates. Study participants underwent a 10-day high-calorie protocol followed by a 10-day fast. Read More
