Anatomy Understanding the tibiofibular syndesmosis needs an inclusive knowledge of the surrounding anatomic structures. Talocrural joint The ankle, or talocrural joint, is a modified-hinge, uniaxial joint formed by the medial malleolus of the tibia, the talus and the lateral malleolus of the fibula. Specifically, the convexsuperior articular surface of the talus or trochlea articulates with the concave distal articular facet of the tibia. The medial malleolus articulates with the medial aspect of the trochlea whereas the lateral malleolus articulates with the lateral aspect of the trochlea. Stability of the ankle mortise is enhanced because the talus has dome shaped body fits snugly into the slightly concave tibial undersurface. The relation of the tibia, fibula, and talus is maintained by an articular capsule and 3 groups of ligaments (medial, lateral,and syndesmosis). Tibiofibular Syndesmosis: The articulation between the tibia and fibula can be divided into three zones: the proximal tibiofibular joint, the interosseous membrane and the distal tibiofibular joint or distal tibiofibula syndesmosis. The proximal tibiofibular syndesmotic joint stabiliezed by posterior superior tibiofibular and anterior superior tibiofibular ligaments, this …show more content…

The fibula sits in a groove created by bifurcation of the lateral ridge of the tibia into the anterior and posterior margins of the tibia, approximately 6-8cm above the level of the talocrural joint. The anterior margin ends in the anterolateral aspect of the tibial plafond called the anterior tubercle, or Chaput’s tubercle. The posterior margin ends in the posterolateral aspect of the tibial plafond called the posterior tubercle, or Volkmann’s tubercle. The apex of this fibular notch is the incisura tibialis, which has a depth that

In healthy individuals, anterior rotation of the innominate occurs during extension of the freely swinging leg. When the innominate anteriorly rotates, it glides inferiorly down the short arm and posteriorly along the long arm of the SIJ. In non-weights bearing an arthrokinematic glide between the innominate and the sacrum occurs during posterior rotation of the innominate and is physiological (i.e., follows the articular surfaces). In weight bearing, the close-packing of the SIJ precludes this physiological glide. Sacral nutation produces the same relative arthrokinematic glide as posterior rotation of the innominate (inferoposterior motion of the sacrum is the same as anterosuperior motion of the innominate); sacral counternutation produces the same arthrokinematic glide as anterior rotation of the innominate (anterosuperior motion of the sacrum is the same as inferoposterior motion of the

When injuries of this type and severity happen to the tibia and thalus the joint rarely returns to its normal function. As the blood supple to the surrounding cartilage is damaged leading to arthritis and the the bones never truly align correctly. Dave will have to be traction to try and straighten the ankle while under heavy medication for both pain and two relax the muscles. 4.

The deformation known as clubfoot is a standout amongst the most widely recognized birth imperfections including the musculoskeletal framework. It presents intrinsic dysplasia of every single musculoskeletal tissue distal to the knee. It is a deformity in which the foot is twisted so that the sole cannot be placed flat on the ground. Understanding the microscopic structure of diseased tissues that characterize clubfoot are very important areas of research. The major component of the ligament, muscle, tendon, bone and joint cartilage involved in clubfoot is collagen.

In adults, these bones are completely fused and their bodies form the cavity for the articulation with the femur, the acetabulum (8). The acetabulum is a deep cotyloid cavity in which all three pelvic bones contribute. It is composed of the body of ilium craniolaterally, the body of ischium caudolaterally and the body of pubis medially. The acetabulum is reciprocal to the head of femur, with which it forms the spheroidal hip joint. The acetabular cavity consists of the peripheral articular lunate surface and the non-articular acetabular fossa in the center.

This structure represents both the anterior and posterior columns of the acetabulum. The anterior column is much longer than the posterior one and extends from the anterior portion of the iliac crest superiorly all the way down to the Symphysis Pubis (SP), while the posterior column travels from the lowermost end of the ischium to meet with the posterior aspect of the anterior column just above its mid-point, almost at the level of the upper corner of the GSN, creating a 60° angle. The acetabulum is enclosed within this angle and the apex is filled with condense cortical bone forming the roof for the

Well-vascularized connective tissue lies between the two ulnar fascicles. A less common insertion is a broad-based striated fascicle attachment along the entire length of the ulnar styloid. In an axial cross section, the TFC appears as an equilateral triangle. In the periphery (limbus), which consists of lamellar collagen fibers, the triangular fibrocartilage is thicker (up to5mm) than in the center. This difference in thickness causes a biconcave disk-shaped appearance in sagittal and coronal cross-sections.

Introduction Foot and ankle problems are quite common in the community. To put this in perspective at any given time 10-15% of population suffers from heel pain alone. Unfortunately, due to a number of interlinked structures it can be hard to diagnose and treat these problems. There are 26 bones, 33 joints and over 100 muscles, tendons and ligaments involving foot & ankle.

Collagen’s Role in Temporomandibular Joint Health The resilience and functions of your temporomandibular joint are supported by collagen architecture. Unlike other joints in the body, the TMJ is composed of fibrocartilage, which contains both Type I and Type II collagen. TMJ disorders are characterized by the excess degradation of collagen, the main building block of cartilage. Cartilage in the TMJ is often degraded due to jaw misalignment.

The restoration of ideal position pairs with Root theory, while achieving coordinated muscle activity pairs with the Tissue Stress Theory The root theory is built around achieving a predetermined neutral STJ position (described as neither in pronation, nor in supination), along with other ideal parameters. The Root theory explains that any deviation from the ideal criteria of foot position will result in the presence of a pathology and reduce gait efficiently (Ball & Afheldt, 2002, Daniel & Colda 2012). In Mrs. Snow’s case, the restoration of the – supinated left STJ, pronated right STJ, excessive rearfoot varus (left and right), and forefoot abduction of the right foot would be addressed.

According Randell Wexler, there are approximately one million ankle sprains in the United States of America per year, and most of these sprains are from inversion injuries. An inversion injury is when the ankle is turned inward beyond the ligament stretching ability (Bays). Ankle sprains can happen many different ways, some include; running on uneven surfaces, landing incorrectly from a jump, and slipping off a curb. As with many injuries, there are different levels of severity-- for ankle sprains these levels are called grades (“Torn Ligaments of the Ankle”). The seriousness of the ankle sprain increases from least severe to most severe in a range of one to three.

Temporomandibular Joint is a hinge that connects the upper jaw (bone of the skull) and lower jaw (mandible of the jaw) to one another, it is also responsible for the movement of the jaw side to side, forward, and backwards. The temporomandibular joint is comprised of the outside parts of the mandibular fossae of the temporal bone, other ligaments, and parts of the eminences and mandible. This joint is one of the most complex joints in the human body. You can see a lot of the movement of the joint if you open your mouth wide enough. Temporomandibular Joint is usually a result of issues that occur within the jaw, or surrounding muscles in the jaw.

Anatomical Structure In Figure 1.1 shown below you can see the Anatomical Structure of the foot and the different bones that make up the Toes, or Phalanges as they are also known. As you can see from the image below, the metatarsals are connected to the Ankle bones via the Tarsometatarsal Joint. It is the Metatarsals however that the Phalanges attach to. The Proximal Phalanges are attached to the Metatarsals via the Metatarsophalangeal Joints which are the joints found at the base of the toes.
