Surgical Repair of Dynamic Snapping Biceps Femoris Tendon

2018 Arthroscopy

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 […]

Changes in the Neurovascular Anatomy of the Shoulder After an Open Latarjet Procedure

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 […]

Qualitative and Quantitative Anatomy of the Proximal Humerus Muscle Attachments and the Axillary Nerve: A Cadaveric Study

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 […]

Comparison of 3-D Shoulder Complex Kinematics in Individuals with and without Shoulder Pain, Part 1

JOURNAL OF ORTHOPAEDIC & SPORTS PHYSICAL THERAPY 2014

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 […]

Comparison of 3-Dimensional Shoulder Complex Kinematics in Individuals With and Without Shoulder Pain, Part 2

JOURNAL OF ORTHOPAEDIC & SPORTS PHYSICAL THERAPY 2014

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 […]

Comparison of glenohumeral motion using different rotation sequences

JOURNAL OF BIOMECHANICS 2011

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.

Shoulder kinematics during the wall push-up plus exercise

JOURNAL OF SHOULDER AND ELBOW SURGERY 2010

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 […]

Comparison of Scapular Local Coordinate Systems

CLINICAL BIOMECHANICS 2010

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.

Motion of the Shoulder Complex During Multiplanar Humeral Elevation

JOURNAL OF BONE AND JOINT SURGERY 2009

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 […]

Assessment of Scapulohumeral Rhythm During Unconstrained Overhead Reaching in Asymptomatic Subjects

JOURNAL OF SHOULDER AND ELBOW SURGERY 2009

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.
