Effects of rotator cuff tears on glenohumeral capsule strain
Rotator cuff tears (RCTs) account for more than 4.5 million physician visits annually in the United States and are a primary source of shoulder pain and dysfunction. Approximately 250,000 rotator cuff repair surgeries are performed each year, and the success rate of repair is variable with 20% to …

Development of a Clinical Pathway for Patients with Chronic Rotator Cuff Tears
… presenting to the healthcare system with chronic rotator cuff tears. Specifically, the research questions examines what gaps in quality of care exist in the current system based on a comparison of the ideal and current standards of care for patients presenting to the healthcare system with chronic …

IMPLICATIONS OF AGING AND DEGENERATIVE ROTATOR CUFF TEARS FOR UPPER LIMB MUSCLE MORPHOLOGY, STRENGTH, AND FUNCTION
… that can be exacerbated by a degenerative rotator cuff tear, a common injury predominantly affecting older adults. Many important tasks necessary to maintaining independence require strength and coordination in the upper limb. The objective of this dissertation was to evaluate the …

Anatomical Variations and Degenerative Features of the Coracoacromial Ligament (CAL) in Shoulders with Rotator Cuff Tears
… etiology of subacromial impingement syndrome and rotator cuff tears. A knowledge and understanding of these variations will help to determine how such variations may influence the surrounding tissues and how the biomechanics of the shoulder works, as well as improving accurate diagnosis and …

The Impact of Psychosocial Factors on the Outcome of Surgical Repair for Rotator Cuff Tears – A Prospective Cohort (IMPROVE Study)
Rotator cuff tears are a common cause of pain and reduced function in the shoulder. The impact of psychosocial factors on patient outcomes following rotator cuff repair (RCR) surgery is unclear. The main goal of this thesis was to determine the association of psychosocial factors and outcomes in …

Neurological Mechanisms Underlying Rotator Cuff Skeletal Muscle Pathophysiology and Implications for Therapy
Introduction: Rotator cuff tears are a common cause of upper-extremity disability. For chronic, full-thickness, rotator cuff tears, repair surgery can be technically challenging due to large gap distances and increased stiffness of the muscle-tendon unit. In contrast, acute rotator cuff tears are …

Muscle structure and function in older adults with a rotator cuff tear
Rotator cuff tears are a highly prevalent musculoskeletal injury affecting 20-50% of older adults, and prevalence increases with more advanced age. Symptoms of a rotator cuff tear include muscle atrophy, fatty infiltration, decreased strength, and a loss of functional ability. However, a healthy …

In vitro simulation of torque-induced rotator cuff damage
Various aspects of rotator cuff tears have been studied in depth, including the primary pathogenesis and mechanical properties. There is, however, a lack of information available on the injury mechanics associated with sudden torque loading of the shoulder. To investigate the mechanical response of …

Patient-Specific Musculoskeletal Modeling of Total Shoulder Arthroplasty
… humeral head fracture, and advancing rotator cuff tears. TSA replaces the articulation between the humeral head and the glenoid fossa, with the goals of relieving pain and restoring function. Two types of total shoulder implants are available: Anatomic Total Shoulder Arthroplasty …

Effect of rotator cuff muscle fatigue on shoulder muscle activation and posture during driving
Rotator cuff (RC) muscle dysfunction impacts the ability to perform daily functional tasks, such as driving. It has been suggested that RC muscle fatigue can mimic rotator cuff tears (RCT) during sudden steering in terms of kinematics. It has also been found that two RC muscles (infraspinatus and …

Mapping the relationship between morphology and function of the shoulder: implications for human evolution and musculoskeletal injury
… and specific shape features are correlated with rotator cuff injury. This suggests that variation in bone morphology alters the mechanical function of the shoulder on a large, interspecific scale (influencing behaviours across species) and on a smaller, intraspecific scale (impacting propensity …

Understanding factors affecting tendon healing: Characterising the role of obesity on tendon healing and homeostasis and augmenting its effects with growth factors
… an increasingly ageing and active population. Tears of rotator cuff tendons are common and result in substantial morbidity and healthcare costs. Recently, obesity has emerged as a key and potentially modifiable risk factor for impaired tendon healing. Aims: This thesis aimed to understand …

Biomechanical assessment of RTSA functional outcomes towards optimising the prosthesis configuration
… pain and restores function to patients with cuff tear arthropathies or massive rotator cuff tears. The procedure uses a semi-constrained prosthesis to reverse the orientation of the glenohumeral joint, thereby altering the biomechanics of the deltoid and allowing it to restore shoulder …

Optimisation of insertion point during latissimus dorsi tendon transfer
Problem and Motivation: Posterior rotator cuff injuries are common (Yamaguchi et al., 2006), (Neri et al., 2009) and often debilitating and irreparable (Sim et al., 2001). Latissimus dorsi (LD) tendon transfers have been shown to be an effective treatment for these massive or irreparable tears …
