a. Normal Anatomy and Biomechanics of the Knee Fred Flandry, MD, FACS*w and Gabriel Hommel, MD* Abstract: Functionally, the knee comprises 2 articulations—the patellofemoral and tibiofemoral. Multibody skeletal models can improve motion capture accuracy by reducing the space of possible joint movements, and models are used widely to … This paper. The shoulder's ability for multiple degrees of motion is based on the interaction of multiple structures that react to mechanical stimuli and adjust accordingly. 7 Full PDFs related to this paper.

Keywords: biomechanics; shoulder; joint stability; muscles; kinematics INTRODUCTION The glenohumeral joint has the widest range of motion of any diarthrodial joint in the body, but little inherent stability is provided by its articular surfaces. Clinical Biomechanics. Range of Motion. Stability of the joint is governed by a combination of static ligaments, dynamic muscular forces, meniscocapsular aponeurosis, bony topography, and joint load. Deltoid force was maximal with the arm abducted 90°, and was calculated to be 8.2 times the weight of the extremity. Deutch SR, Jensen SL, Olsen BS. Sternum GLENOHUMERAL JOINT 1/3 1/4. The authors use good diagrams to review the structure of each joint but, with the possible ex- ception of the shoulder, do not cover the detail of the specific ligament and muscle action.

This presentation is the intellectual property of the author. During most of the ROM arch, there is no strain on the ligaments, these remain loose until a certain a point in which tension increases suddenly and quickly. The scapula extends up and around the shoulder joint at the rear to form a roof called the acromion, and around the shoulder joint at the front to form the coracoid process. Shoulder ligaments only act in the extreme positions of the range of motion (ROM), and remain lax if the shoulder is at rest or during non-extreme ROM . • It's tendon passes through the shoulder joint and emerges beneath the transverse humeral ligament. • Inside the joint, the tendon is surrounded by a separate tubular sheath of the synovial capsule.
