A snapping biceps tendon is an infrequently seen and commonly misdiagnosed pathology, leaving patients with persistent symptoms that can be debilitating. Patients will present with a visible, audible, and/or painful snap over the lateral aspect of their knee when performing squats, sitting in low seats, or participating in […]
The Latarjet procedure, which was first described in 1954, has emerged as a common surgical option for recurrent anterior shoulder instability with positive clinical outcomes. Typically, the Latarjet procedure is indicated when anterior glenoid bone loss reaches 20% to 25% because this has been reported to be the critical […]
Purpose: To provide a quantitative and qualitative anatomic analysis of the pectoralis major, teres major, and latissimus dorsi on the humerus, as well as the deltoid tendinous attachments on the proximal humerus and acromion, and to quantitatively characterize the humeral course of the axillary nerve.
Methods: Ten nonpaired, fresh-frozen human […]
Shoulder pain is the second most common musculoskeletal complaint, with a reported point prevalence of 20.9% of the general population. In part one of this study the objective is to compare sternoclavicular, acromioclavicular, and scapulothoracic joint motion between symptomatic and asymptomatic individuals during shoulder motion performed in 3 […]
The clinical diagnosis of impingement is the most common diagnostic label for shoulder pain. However, the diagnosis is so broadly applied that different tissue pathologies and various and often conflicting pathomechanics may contribute to the pain. The objective in part two of this study is to compare differences […]
Glenohumeral motion presents challenges for its accurate description across all available ranges of motion using conventional Euler/Cardan angle sequences without singularity. A comparison of the description of glenohumeral motion was made using the ISB recommended YX´Y” sequence to the XZ’Y” sequence.
The push-up plus exercise is a common therapeutic exercise for improving shoulder function and treating shoulder pathology. To date, the kinematics of the push-up plus exercise have not been studied. Our hypothesis was that the wall push-up plus exercise would demonstrate increased scapular internal rotation and increased humeral anterior translation during the […]
Background: Our purposes were to compare between the original and current recommended standard methods of three-dimensional scapular rotation descriptions and to examine the prevalence of gimballock for scapular motion during scapular plane abduction. Additionally we compared these standards to an alternative method and a glenoid based description.
Many prior studies have evaluated shoulder motion, yet no three-dimensional analysis comparing the combined clavicular, scapular, and humeral motion during arm elevation has been done. We aimed to describe and compare dynamic three-dimensional motion of the shoulder complex during raising and lowering the arm across three distinct elevation planes […]
The contribution of scapulothoracic and glenohumeral motion to overall shoulder motion remains difficult to determine. We sought to determine the exact ratio between these two motion components in order to better understand overall shoulder kinematics in asymptomatic individuals in unconstrained reaching.
