Total Elbow Arthroplasty Versus Open Reduction and Internal Fixation for the Management of Distal Humerus Fractures in the Elderly.

Orthopedics 2018 Dec 11:1-6. Epub 2018 Dec 11.

Distal humerus fractures, which are challenging injuries seen in geriatric patients, are often repaired using open reduction and internal fixation or total elbow arthroplasty. This updated meta-analysis, which includes more recent open reduction and internal fixation techniques, examined outcomes following distal humerus fractures repaired using open reduction and internal fixation vs total elbow arthroplasty. Although distal humerus fractures treated with total elbow arthroplasty achieved statistically higher functional scores relative to those treated with open reduction and internal fixation, this difference was not clinically significant.

Combined Ipsilateral Humeral Shaft and Galeazzi Fractures Creating a Floating Elbow Variant.

Case Rep Orthop 2018 8;2018:7430297. Epub 2018 Nov 8.

Department of Orthopaedic Surgery, New York-Presbyterian Hospital, New York, USA.

"Floating elbow" injuries of the arm traditionally represent a combination of humeral shaft and forearm fractures which require anatomic rigid open reduction and internal fixation of all fractures to allow for early range of motion exercises of the elbow. There are published variants of the floating elbow injury which include ipsilateral diaphyseal humeral fracture, proximal ulna fracture with proximal radioulnar joint disruption, and ipsilateral diaphyseal humeral fracture with elbow dislocation and both bones forearm fracture. We present the case of a 21-year-old woman whose left arm became caught between the side of a waterslide and adjacent rocks at a park. Read More

The Force Generation in a Two-Joint Arm Model: Analysis of the Joint Torques in the Working Space.

Front Neurorobot 2018 23;12:77. Epub 2018 Nov 23.

Unit of the Theory of Sport and Motorics, Chair of Individual Sports, University of Physical Education and Sport, Gdańsk, Poland.

The two-segment model of the human arm is considered; the shoulder and elbow joint torques (JTs) are simulated, providing a slow, steady rotation of the force vector at any end-point of the horizontal working space. The sinusoidal waves describe the JTs, their periods coincide with that of the rotation, and phases are defined by the slopes of the correspondent lines from the joint axes to the end-point. Analysis of the JTs includes an application of the same discrete changes in one joint angle under fixation of the other one and vice versa; the JT pairs are compared for the "shoulder" and "elbow" end-point traces that pass under fixation of the elbow and shoulder angles, respectively.

Research and Development, Driveline Baseball, Inc, Kent, WA, United States of America.

Background: Weighted-baseball training programs are used at the high school, collegiate, and professional levels of baseball. The purpose of this study was to evaluate the effects of a six-week training period consisting of weighted implements, manual therapy, weightlifting, and other modalities on shoulder external rotation, elbow valgus stress, pitching velocity, and kinematics.

Hypothesis: A six-week training program that includes weighted implements will increase pitching velocity along with concomitant increases in arm angular velocities, joint kinetics, and shoulder external rotation. Read More

Correlation of compound muscle action potential generated by donor nerves with the recovery of elbow flexion in Oberlin transfer in brachial plexus injury.

Indian J Plast Surg 2018 May-Aug;51(2):137-144

Department of Plastic Surgery, Bombay Hospital and Institute of Medical Sciences, Mumbai, Maharashtra, India.

Objective: To study the correlation of compound muscle action potential of donor nerves with the recovery of elbow flexion in Oberlin transfer in brachial plexus injury.

Introduction: Distal nerve transfer using motor fascicle of ulnar or median nerve to restore elbow flexion is a part of reconstructive surgery after upper brachial plexus injury, first described by Oberlin . However, one of the most critical influences on functional outcome is number of functioning motor axons in donor fascicle which is reflected by its compound muscle action potential. Read More

Total knee arthroplasty in a patient with nail-patella syndrome (NPS).

Knee 2018 Nov 29. Epub 2018 Nov 29.

Houston Methodist Othopedics & Sports Medicine, Houston, TX, United States of America. Electronic address:

Nail-patella syndrome (NPS) or hereditary onycho-osteodyaplasia is a rare genetic condition involving a mutation in the LMX1B gene affecting nails, elbows, knees, and pelvis. Due to the regulatory functions of the gene in many developmental processes through the body, patients with NPS experience wide-ranging musculoskeletal problems including patellar instability, fingernail anomalies, iliac exostoses/horns, and elbow abnormalities. The patellar changes often involve aplasia, hypoplasia, and chronic dislocation. Read More
