Joints

The temporomandibular joint is one of the most complex joints in the body. The procedure that we covered is total alloplastic joint replacement. Like any other procedure, reflection, incision, resection as well as re attachment of biological tissues is necessary for successful completion. In the case of the total replacement of the temporomandibular joint the musculature that is affected are the temporalis, lateral pterygoid, medial pterygoid, masseter as well as buccinator. As for the tissues that will be removed and replaced, they are the mandibular fossa, joint disc, mandibular condyle and ramus. The remaining of this section will describe in detail how these tissues are affected by the surgical procedure as well as how the surgery affects…

The knee joint is classified as a type of synovial joint, which is one of the most common and complex joints found in the human body. The knee is a meeting point for the femur, fibula, tibia, and the patella. In order to maintain its flexibility and function, several other ligaments join the knee joint in order to keep the attaching bones in place. The knee is the joint where the femur and the tibia meet; the patella (kneecap) is made of bone and sits in front of the knee. The knee joint is a…

In order for a synovial joint to perform its best it works as a team. After all we know that when you work with a team things get done a lot more efficiently and less work gets put on one single person. In this case the synovial joint is surrounded by the following structures: Tendons which attach our muscles to the bone, ligaments which attach bone to bone, Bursae, which are small sacs of extra synovial fluid that provide extra cushion and protection to the synovial joint. These structures help…

In this article, different subtalar joint positioning during gastrocnemius stretching was investigated to conclude wether or not the position of the subtalar joint had significant effect on dorsiflexion ROM. . Patients with ankle oversee injuries, and patients with limited dorsiflexion ROM, are often prescribed stretches for the gastrocnemius calf muscle as part of their rehab program. (JAT, NATA). The idea behind this is that the tight calf muscles may have an negative effect on reaching…

Movement: -The positioning of the bones forming the elbow joint produce the hinge synovial joint. This allows the elbow to make extensions and flexion. The extension involves the Triceps brachii and anconeus (the continuation of the tricep brachii). Flexion is involving the; Brachialis, biceps brachii, and brachioradialis. - The bending of a joint part so that the angle decreases and the two parts come closer together, it called Flexion. The straitening of a joint increasing the two parts to…

Joint pains and inflammation causes Knee is that largest joint in the body. The knee is located at the juncture of three bones, the femur, the tibia and the patella. The femur (the upper leg bone) and the tibia (the shinbone) are connected by the anterior and posterior cruciate ligaments. The joint is cushioned by the meniscus, a tough cartilage material, during movement. The patella (or kneecap) is a small bone, encased in tendons, that glides up and down in the groove on the top of the femur…

Two joint range of motion (ROM) of two patients, one in upper limb and one in lower limb, are measured and the data is recorded. The first ROM measured is the angle made between shank and posterior thigh, which is the angle for knee extension. The relative position of the patient and the therapist are standardized with patient sitting over the edge of the bed, keeping the trunk straight, while the therapist standing on knees close the side of legs being measured. Moving and stationary body…

Introduction Glenouhumeral Joint The glenohumeral (GH) joint, which is also known as shoulder joint, is a multiaxial ball-and-socket synovial joint. This joint is responsible for connecting the upper extremity of the trunk. The glenohumeral joint is one of the four joints that comprise the shoulder complex. The joint is considered to be the most mobile and least stable joint. The articular surfaces of the glenohumeral joint are the head of humerus and glenoid fossa of scapula. The humeral…

1. For each timber joint listed provide a pencil drawing and an explanation of where it could be used. Butt Joint- The butt joint one of the most basic and simple joints to construct as it is made with only two pieces of timber that are put together at the ends. This means that the joint isn't very strong. In fact it is the weakest joint in woodwork but it is the easiest to make. This joint is held together with glue, nails and screws but can also be secured with a combination of methods to…

The wrist or carpus is a highly mobile structure composed of many small bones and joints. In the anatomy of the human hand, a total of 13 bones form part of the wrist- eight carpal bones- scaphoid, lunate, triquetral, pisiform, trapezium, trapezoid, capitate and hamate; and five metacarpal bones which are joined along with two long bones of the forearm- the radius and the ulna (Platzer 2004). This complex system of articulations works in unison to provide a global range of motion for the wrist…
