It consists of three fascial attachments at the knee joint (18, 21) was identified posterior to the biceps tendon. The iliotibial band was incised in line with its fibers beginning at the point where it crosses the lateral femoral epicondyle and proceeding distally. This exposed the insertion point of both the fibular collateral ligament as well as the popliteus tendon on the lateral femoral condyle Accessory navicular. Dr Henry Knipe and Assoc Prof Frank Gaillard et al. An accessory navicular is a large accessory ossicle that can be present adjacent to the medial side of the navicular bone. The tibialis posterior tendon often inserts with a broad attachment into the ossicle. Most cases are asymptomatic but in a small proportion it may.

Segond Fracture. Segond fracture is probably the best known and most discussed avulsion fracture of the knee. Originally described by the French surgeon Paul Segond in 1879 after a series of cadaveric experiments (, 1), this fracture involves cortical avulsion of the tibial insertion of the middle third of the lateral capsular ligament (, 2).More recent cadaveric studies have suggested that. The posterior cruciate ligament (PCL), is one of four ligaments important to the stability of the knee joint. The anterior cruciate ligament (ACL), sits just in front of the PCL.The ACL is much better known, in part because ACL tears are much more commonly diagnosed than injuries to the PCL. Interestingly, it is thought that PCL injuries account for up to 20 percent of knee ligament injuries. The results of meniscus posterior root repair are good in selected patients, though longer-term follow-up studies are needed to assess the potential chondroprotective effect

The axillary nerve is a risk with low posterior (7 o'clock) portals. The axillary nerve leaves the axilla through the quadrangular space and winds around humerus on deep surface of the deltoid.. Anatomy and physiology. The syndesmosis provides stability for the articulation of the tibia and fibula. The distal fibula rests between the anterior and posterior lateral tibial tubercles to provide bone stability and normally only widens 1 mm.9 Furthermore, if the Chaput's tubercle is too shallow, the patient may be predisposed to recurrent external rotation ankle sprains.10 At the distal. The oblique popliteal ligament is a thin, broad lateral extension of the semimembranosus tendon that covers and blends with the posterior medial capsule and extends beyond the midline of the joint to intertwine its fibers with the arcuate ligament from the lateral posterior aspect of the knee ( Fig. 91-7 )

The apical, alar, and transverse ligaments, by allowing spinal column rotation, provide further stabilization and prevent posterior displacement of the dens in relation to the atlas (Fig.3). Axis (C2): It as a large vertebral body, which contains the odontoid process (dens) and is composed of a vertebral body, heavy pedicles, laminae, and. There's a ligament on the back of the vertebral body called the posterior longitudinal ligament; that's part of the middle column as well. If there's a fracture in the middle column in addition to the anterior or posterior column, you're much more likely to have nerve damage and spinal instability. As long as the middle column stays intact, you. The Posteriolateral compartment (PLC) can be described as consisting of 5 structures (2 muscles and 3 ligaments); the lateral head of the gastrocnemius, the popliteus, the popliteofibular ligament, the lateral collateral ligament (LCL), and the arcuate ligament-fabellofibular ligament complex

Fibular fractures in adults are typically due to trauma. Isolated fibular fractures comprise the majority of ankle fractures in older women, occurring in approximately 1 to 2 of every 1000 white women each year [ 1 ]. Fibular fractures may also occur as the result of repetitive loading and in this case they are referred to as stress fractures Created with lines drawn tangiental to anterior and posterior aspects of superior calcaneus.

Meniscal root tears are defined as radial tears located within 1 cm from the meniscal attachment or a bony root avulsion. This injury is biomechanically comparable to a total meniscectomy, leading to compromised hoop stresses resulting in decreased tibiofemoral contact area and increased contact pressures in the involved compartment The anterior oblique ligament is functionally subdivided into anterior and posterior bands; it is widely considered to be the primary restraint to valgus stress. The lateral or radial side, known as the lateral collateral ligament complex, has four components: the lateral (or radial) ulnar collateral ligament, the radial collateral ligament. Fractures of the Lateral Talar Process. - Discussion: - two processes, lateral & posterior, project from body of talus; - either process may be fractured, either as isolated injury or assoc w/ other ankle or talar injuries; - it is frequently confused w/ an ankle sprain; - non union is a frequent complication of displaced lateral process frx Shapiro et al 2 found these two provocative tests to be positive in all patients with a rupture of Lisfranc's ligament. More often, passive pronation and abduction of the midfoot elicits the most pain and reproduces the patient's symptoms. 11. Imaging. Initial radiographs of the foot include anteroposterior, 30 degree oblique and lateral views The medial epicondyle is an apophysis on the posterior-medial aspect of the distal humerus that serves as the origin of the flexor-pronator muscle mass and the primary origin of the ulnar collateral ligament (UCL). Injuries causing excessive traction on these structures may result in an epicondylar avulsion fracture (Pathy, 2015; Gottschalk.

Now you start looking for stage 4 and you will notice the subtle lucency in the medial. A meniscus root tear happens when the root attachment is torn or destabilized. Most meniscus root tears actually are not the root tearing, but actually a tear of the meniscus within 1 cm of the root. These are called radial root tears and are about 90% of all meniscal root tears. A meniscus root tear can totally destabilize the shock absorbing. Annular ligament Located at the proximal radioulnar joint. Surrounds radial head and radial notch of ulna; Keeps radial head in radial notch; allows pronation and supination (Hansen, 2010, p. 315). Ulnar collateral ligament Is triangular ligament with anterior, posterior, and oblique bands at the humeroulnar joint (Hansen, 2010, p. 315) The Deltoid ligament (or the medial ligament of talocrural joint) is a strong, flat and triangular band.It is made up of 4 ligaments that form the triangle, connecting the tibia to the navicular, the calcaneus, and the talus.It is attached above to the apex and anterior and posterior borders of the medial malleolus.The plantar calcaneonavicular ligament can be considered as part of the medial. Ligament Anatomy The lateral and medial malleoli have ligamentous attachments to the talus and calcaneus that contribute to stability of the joint. The lateral ligamentous complex is composed of the posterior talofibular ligament (PTFL), anterior talofibular ligament (ATFL) and the calcaneofibular ligament (CFL)

The anterior (volar) oblique ligament originates on the trapezium and inserts into the volar ulnar beak of the thumb metacarpal. This is the most important ligament in maintaining CMC stability. The dorsal ligament is not as strong as the volar ligament but is reinforced by the abductor pollicis longus (APL) Interosseous membrane labeled at bottom center. The interosseous membrane of the forearm (rarely middle or intermediate radioulnar joint) is a fibrous sheet that connects the interosseous margins of the radius and the ulna. It is the main part of the radio-ulnar syndesmosis, a fibrous joint between the two bones Ankle fractures are breaks of the distal tibia or fibula (near or in the so-called malleolus) affecting the tibiotalar (ankle) joint. Occasionally, they involve the shaft of the fibula as well. Ankle fractures range from simple injuries of a single bone to complex ones involving multiple bones and ligaments
