Distal Insertional Footprint Of The Brachialis Muscle: 3d Morphometric Study, Srinath Kamineni, Abdo Bachoura, William Behrens, Ellora Kamineni, Andrew Deane

Orthopaedic Surgery and Sports Medicine Faculty Publications

Objective. The purpose of this study is to describe the three-dimensional morphometry of the brachialis muscle at its distal attachment to the ulna. Methods. Fifty cadaveric elbows were dissected and the brachialis distal insertion was isolated on the ulna bone and probed with a three-dimensional digitizer, to create a three-dimensional model of the footprint. Measurements and analysis of each footprint shape were recorded and compared based on gender and size. Results. There was significant gender difference in the surface length (P = 0.002) and projected length (P = 0.001) of the brachialis footprint. The shapes …

Inner Synovial Membrane Footprint Of The Anterior Elbow Capsule: An Arthroscopic Boundary, Srinath Kamineni, Abdo Bachoura, Koichi Sasaki, Danielle Reilly, Kate N. Harris, Anthony Sinai, Andrew Deane

Orthopaedic Surgery and Sports Medicine Faculty Publications

Introduction. The purpose of this study is to describe the inner synovial membrane (SM) of the anterior elbow capsule, both qualitatively and quantitatively. Materials and Methods. Twenty-two cadaveric human elbows were dissected and the distal humerus and SM attachments were digitized using a digitizer. The transepicondylar line (TEL) was used as the primary descriptor of various landmarks. The distance between the medial epicondyle and medial SM edge, SM apex overlying the coronoid fossa, the central SM nadir, and the apex of the SM insertion overlying the radial fossa and distance from the lateral epicondyle to lateral SM edge along the …

Percutaneous Ultrasonic Debridement Of Tendinopathy—A Pilot Achilles Rabbit Model, Srinath Kamineni, Timothy Butterfield, Anthony Sinai

Orthopaedic Surgery and Sports Medicine Faculty Publications

BACKGROUND: Tendinopathy is a common clinical pathology, with mixed treatment results, especially when chronic. In this study, we examine the effects of an ultrasonic debridement modality in a rabbit tendinopathy model. We asked four questions: (1) Was it possible to create and visualize with ultrasound a tendinopathy lesion in a rabbit Achilles tendon? (2) Was it possible to guide a 19-gauge ultrasonic probe into the tendinopathy lesion? (3) Following ultrasonic treatment, was tendinopathy debris histologically present? and (4) Was the collagen profile qualitatively and quantitatively normalized following treatment?

METHODS: Skeletally mature female New Zealand white rabbits (n = 12) …

Triceps Activation Amplitudes During Functional Activities, Srinath Kamineni, Corey Gildea, Arthur J. Nitz, Timothy L. Uhl

Orthopaedic Surgery and Sports Medicine Faculty Publications

Objective: To investigate the muscular activation amplitudes of three regions of triceps musculature during functional activities. We hypothesized that the medial and lateral triceps would be greatest in the terminal 30° arc of extension activities.

Design: Cross sectional.

Setting: Musculoskeletal Clinical Laboratory.

Participants: 20 healthy subjects recruited from a sample of convenience.

Intervention: Fine wire electromyograhical (EMG) electrodes were placed into the medial, central, and lateral triceps to measure muscular activation amplitude and two dimensional electrogoniometric kinematic activity was recorded during functional activities associated with activities of daily living.

Main Outcome Measure(s): Root mean squared amplitudes of triceps muscles normalized …

Characteristics Of Clinical Shoulder Research Over The Last Decade: A Review Of Shoulder Articles In The Journal Of Bone & Joint Surgery From 2004 To 2014, Gary M. Gartsman, Brent J. Morris, R. Zackary Unger, Mitzi S. Laughlin, Hussein A. Elkousy, T. Bradley Edwards

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background: The purpose of this study was to determine characteristics and trends in published shoulder research over the last decade in a leading orthopaedic journal.

Methods: We examined all clinical shoulder articles published in The Journal of Bone & Joint Surgery from 2004 to 2014. The number of citations, authorship, academic degrees of the authors, country and institution of origin, topic, level of evidence, positive or nonpositive outcome, and inclusion of validated patient-reported outcome measures were assessed for each article.

Results: Shoulder articles that included an author with an advanced research degree (MD [Doctor of Medicine] with a PhD …
