The Effects Of Vitamin D Supplementation On Athletic Performance And Injury Prevention, Amani Adeeb Abushamma

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Vitamin D supplementation has numerous effects on athletic performance and plays a significant role in preventing an athlete’s risk of getting injuries. Vitamin D has an impact on numerous physiological functions such as: bone health, muscle function, inflammatory response, and immune function. An athlete’s bone and muscle health are essential for maximum performance and career success. A bone fracture due to vitamin D deficiency can delay an athlete’s training and ultimately inhibit obtaining a collegiate scholarship and/or contract. A cross sectional study found that more than half of athletic trainers did not view 25-hydroxyvitamin D(25[OH]) testing and vitamin D supplementation …

Is Blood Flow Restriction Training Superior For The Limitation Of Hamstring And Quadriceps Atrophy After Anterior Cruciate Ligament Reconstruction? A Review Of Randomized Controlled Trials, Joshua M. Spada, Ryan W. Paul, Bradford S. Tucker

Rowan-Virtua Research Day

Post operative recovery from Anterior Cruciate Ligament Reconstruction (ACLR) includes extensive rehabilitation of 6-9 months with return to sport/activity at 12 months

Rehabilitation is initiated shortly following surgery to limit quadriceps and hamstring atrophy, maximizing long term tibiofemoral joint stability and functional outcomes

The best way to achieve improved muscle strength and prevent atrophy is progressive overload training, however, these activities cannot be performed post operatively without risk to the reconstructed knee

Blood Flow Restriction Training (BFR) involves impairing the blood supply for short periods through the application of an air-filled bladder or cuff to restrict the venous drainage of …

Latarjet Surgery Leads To Decreased Rates Of Subjective Instability Compared To Bankart Repair With Concomitant Remplissage, Joshua Spada, Ryan W. Paul, Manoj Reddy, Gabriel Onor, John Hayden Sonnier, Ari Clements, Meghan E. Bishop, Brandon J. Erickson

Rowan-Virtua Research Day

Background: Predictive factors for performing remplissage concomitantly with arthroscopic Bankart repair include the presence of humeral or glenoid defects >11% and/or revision surgery. International and societal consensus statements support these findings, as surgeons recommend the Latarjet procedure for patients with significant glenoid bone loss (>15-20%) while remplissage is recommended for patients with off-track or engaging Hill-Sachs lesions without significant glenoid bone loss. While several studies have compared outcomes between Latarjet surgery and remplissage, these studies have only evaluated patients with engaging Hill-Sachs lesions, not consecutive patient cohorts indicated for each surgery.

Purpose: To compare rates of recurrent instability, re-operation, …

Does Prehabilitation Prior To Ulnar Collateral Ligament Surgery Affect Return To Sport Rate Or Time In Baseball Players With Partial Ucl Tears?, Joshua Spada, Kourtney Snigar, Ryan W. Paul, Usman Zareef, Anya Hall, Brandon J. Erickson, Michael G. Ciccotti, Stephen J. Thomas

Rowan-Virtua Research Day

Those who suffer a partial thickness ulnar collateral ligament (UCL) tear often undergo a period of nonoperative management including physical therapy rehabilitation. This treatment is aimed at optimizing range of motion (ROM) and strengthening the supporting structures around the elbow to help offload the UCL.

Unfortunately, some of these patients fail nonoperative management and require surgical intervention. This creates a unique set of patients who essentially underwent “prehabilitation” prior to their UCL surgery. Prehabilitation is considered a period of structured physical therapy rehabilitation aimed at strengthening structures surrounding an injured tendon or ligament, to allow for dissipation of stress away …

Non-Weightbearing In Cam Boots After Foot/Ankle Fracture Fixation: Are Patients Compliant?, Amos Z. Dai, Michelle Regan, Megan Paulus

Stony Brook Orthopaedic and Musculoskeletal Journal

Background: The controlled ankle motion (CAM) boot has become an integral part of the management of both operative and nonoperative foot and ankle conditions. Similar to casts, CAM boots are used to immobilize the foot and ankle after injury or surgery. However, unlike casts, CAM boots can be readily removed for showering and range of motion (ROM) exercises. While CAM boots are well-designed for ambulation and are frequently utilized in early weightbearing (WB) and early ROM protocols, their usage in non-weightbearing (NWB) protocols is less clear.

Purpose: The purpose of the current study is to determine the patient compliance rate …

The Rotator Cuff Tendon-To-Bone Interface: Maturation, Aging, And 3d Bioprinting For Regeneration, Xiping Jiang

Theses & Dissertations

Rotator cuff tendon injuries often occur at the tendon-to-bone interface (i.e., enthesis) area with a high prevalence for the elderly population. In addition, regeneration of the gradient structure of the enthesis is still a significant clinical challenge. Our studies aim to identify the histological, molecular, and biomechanical alterations of the rotator cuff enthesis with maturation and aging, and develop a novel therapeutic method using three-dimensional (3D) bioprinting technique to regenerate a functional enthesis. Striking variations of the entheses were observed both histologically and biomechanically during the maturation process. The histological features did not show many differences at the insertion site …
