Revision Total Elbow Arthroplasty: Is it safe to perform a single-stage revision for presumed aseptic loosening based on clinical assessment, normal inflammatory markers and a negative aspiration?

J Shoulder Elbow Surg 2020 Jun 10. Epub 2020 Jun 10.

Background: Revision Total Elbow Arthroplasty (TEA) is a challenging procedure that is becoming increasingly common. In our unit we regard it as essential to exclude infection as the underlying cause of TEA loosening. In all patients with arthroplasty loosening we undertake a careful history and examination, perform radiographs, monitor inflammatory markers and undertake a joint aspiration. Read More

Elbow angle generation during activities of daily living using a submovement prediction model.

Biol Cybern 2020 Jun 9;114(3):389-402. Epub 2020 Jun 9.

Biomedical Engineering Department, Amirkabir University of Technology, Tehran, Iran.

The present study aimed to develop a realistic model for the generation of human activities of daily living (ADL) movements. The angular profiles of the elbow joint during functional ADL tasks such as eating and drinking were generated by a submovement-based closed-loop model. First, the ADL movements recorded from three human participants were broken down into logical phases, and each phase was decomposed into submovement components. Read More

Adapting a fatigue model for shoulder flexion fatigue: Enhancing recovery rate during intermittent rest intervals.

J Biomech 2020 Jun 28;106:109762. Epub 2020 Apr 28.

Department of Physical Therapy and Rehabilitation Science, University of Iowa, Iowa City, IA 52442, United States.

Although the rotator cuff muscles are susceptible to fatigue, shoulder fatigue studies reporting torque decline during intermittent tasks are relatively uncommon in the literature. A previous modification to the three-compartment controller (3CC) fatigue model incorporated a rest recovery multiplier (3CC-r model) to represent augmented blood flow to muscle during rest intervals (Looft et al., 2018).

Estimating upper extremity joint loads of persons with spinal cord injury walking with a lower extremity powered exoskeleton and forearm crutches.

J Biomech 2020 Jun 8;107:109835. Epub 2020 May 8.

Ottawa Hospital Research Institute, 505 Smyth Road, Ottawa, ON K1H8M2 Canada; University of Ottawa, Faculty of Medicine, 451 Smyth Rd, Ottawa, ON K1H8M5, Canada.

Lower extremity powered exoskeletons with crutch support can provide upright mobility to persons with complete spinal cord injury (SCI); however, crutch use for balance and weight transfer may increase upper extremity (UE) joint loads and injury risk. This research presented the first exoskeleton-human musculoskeletal model to estimate upper extremity biomechanics, driven by 3D motion data of persons with complete SCI walking with an exoskeleton and crutch assistance. Forearm crutches instrumented with strain gauges, force plates, and a 3D motion capture system were used to collect kinematic and kinetic data from five persons with complete SCI while walking with the ARKE exoskeleton.

The forearm and hand musculature of semi-terrestrial rhesus macaques (Macaca mulatta) and arboreal gibbons (Fam. Hylobatidae). Part I. Description and comparison of the muscle configuration.

J Anat 2020 Jun 8. Epub 2020 Jun 8.

Dept. of Development & Regeneration, Biomedical Sciences Group, KU Leuven Campus Kulak, Kortrijk, Belgium.

Primates live in very diverse environments and, as a consequence, show an equally diverse locomotor behaviour. During locomotion, the primate hand interacts with the superstrate and/or substrate and will therefore probably show adaptive signals linked with this locomotor behaviour. Whereas the morphology of the forearm and hand bones have been studied extensively, the functional adaptations in the hand musculature have been documented only scarcely. Read More

The association between glenoid component design and revision risk in anatomic total shoulder arthroplasty.

J Shoulder Elbow Surg 2020 Jun 4. Epub 2020 Jun 4.

Department of Orthopaedics, Southern California Permanente Medical Group, Harbor City, CA, USA.

Introduction: Anatomic total shoulder arthroplasty (TSA) is a proven treatment for glenohumeral joint osteoarthritis, with superior results compared with hemiarthroplasty. However, glenoid component loosening remains a problem and is one of the most common causes of failure in TSA. Multiple component designs have been developed in an attempt to reduce loosening rates.
