Week 7 Case Study: Joints Chamberlain University BIOS251-12278 Week 7 Case Study: Joints Describe the different classes o... f joints based on structure and function. Functional: based on degree of motion or the amount of movement Synarthroses: immovable joints. Found in skull joints, teeth sockets, distal joint of tibia and fibula Amphiarthroses: slightly movable Found in intervertebral joints, pubic symphysis, manubrium, tibiofibular, and body of the sternum. Diarthroses: free movable joints. Found in knee, elbow, shoulder, hip, and carpal bones. Structural: based on the major connective tissue type that binds the bones together. Fibrous joints: bones that are connected by fibrous connective tissue, strong collagen fibers, no synovial cavity. Cartilaginous joints: hyaline cartilage or fibrocartilage, no synovial cavity Synovial joints: small synovial cavity, dense fibrous connective tissue. Found in shoulder, elbow, hip, knee joints, and carpal bones. What class of synovial joint is located in the knee? The hinge joint. These are essentially monaxial (Saladin, 2020), hence they are formed between two or more bones where the bones can only move along one axis to flex(bend) or extend (straighten) but restrict motion to one plane. Describe the location and function of the ACL. The ACL (anterior cruciate ligament) attaches to anterior tibia (Study Guide - Articulations, n.d.). The function of the ACL is to inhibit the tibia from sliding forward on the femur, and to control tibia-femoral rotation. When the knee is extended, the ACL is pulled tight and prevents hyperextension (Saladin, 2020). What does the doctor mean by hemarthrosis? Hemarthrosis is accumulation of blood in a joint cavity, blood-induced joint damage (Pulles et al., 2018). Hemarthrosis can be present after an injury or a bleeding disorder like hemophilia. It is presented with pain, swelling and decreased range of motion of the involved joint (Lombardi & Cardenas, 2021). Do you think Eli will be able to play next year in college? Explain. In the event the hemarthrosis was caused by an intra-articular fracture or significant soft tissue injury, orthopedic surgery may be warranted for these individuals (Lombardi & Cardenas, 2021). Treatment might include surgical repair such as arthroscopic surgical reconstruction with patella tendon or hamstring tendon from an autograft, allograft, or xenograft, for a major tear, a hinge brace/splint, continuous passive motion machine. If Eli’s injury was stable/acute, he would just need to rest, apply ice, use compressions, and elevate his leg also known at the RICE treatment. Eli will likely need surgery which will refrain him from playing football next year. References Lombardi, M., & Cardenas, A. C. (2021, January). Hemarthrosis.
