laxity and increased oblique orientation of the trapezium. Figure 3 A, Dorsal view of the thumb right trapeziometacarpal joint illustrating the posterior oblique ligament (POL), dorsoradial ligament (DRL), abductor pollicis longus (APL), first intermetacarpal ligament (IML), and extensor carporadialis (ECRL) tendon The posterior oblique ligament is a ﬁbrous extension off the distal aspect of the semimembranosus, which blends with and reinforces the posteromedial aspect of the joint capsule (See figure 1). 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
Meniscocapsular Separation. Meniscocapsular separation is a subtype of meniscal tear in which the posterior meniscus horn pulls away from the capsule resulting in a separation of the posterior meniscal signal and the posterior tibial plateau greater than 8-10 mm. 6. Meniscocapsular Separation: Injuries. Meniscocapsular separation is a type of tear which may affect the posteromedial corner (PMC) An avulsion fracture of the head of the fibula has been described as an important indicator of posterolateral instability of the knee. The arcuate sign is used to describe an avulsed bone fragment related to the insertion site of the arcuate complex, which consists of the fabellofibular, popliteofibular, and arcuate ligaments .The mechanism of this injury, which leads to posterolateral.

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. . 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. Normal is 20-40 degrees. Increased angle of Gissane. Formed by downward and upward slopes of calcaneus. Normal is 95-105 degrees. Non-contrast CT.

Thickening of the anterior band of the MCL (arrowhead) with bone fragment (arrow) on (a, and c) Scapholunate Ligament Tear. By Asheesh Bedi, M.D. Although there are many ligaments and injuries in the wrist, a scapholunate ligament tear is the most commonly injured. The scapholunate ligament connects the scaphoid to the lunate. The most important part of the ligament is on the back (dorsal side) of the wrist Supination-external rotation (SER): ~60% of ankle fractures. Stage 1: tear of anterior-inferior tibiofibular ligament (AITFL) or avulsion of anterior tibia. Stage 2:Spiral fracture of the lateral malleolus at and above level of mortise. Stage 3: Tear of the posterior-inferior tibiofibular ligament (PITFL) or avulsion of posterior malleolus
The posterior band is covered and reinforced by the popliteus tendon. 2,11,13 The posterolateral structures of the knee (lateral collateral ligament, arcuate ligament, fabellofibular ligament, popliteofibular ligament, and popliteus muscle) are thought to help stabilize the proximal tibiofibular joint. 14,15 The biceps femoris tendon inserts on. This may lead to a medial malleolar fracture, tear of the anteroinferior tibiofibular ligament, oblique or spiral fracture of the midshaft of the fibula (white arrow), and fracture of the posterior malleolus. The midshaft fibula and posterior malleolus fractures distinguish this fracture pattern from the pronation-abduction mechanism TENDON TRANSFER COMBINED WITH CALCANEAL OSTEOTOMY FOR TREATMENT OF POSTERIOR TIBIAL TENDON INSUFFICIENCY -18 patients (12-26 m = average follow-up) -Mean improvement of TFMA = 12.5 degrees -Mean improvement of TNJ coverage angle = 13 degrees -Mean improvement of distance of MC to floor = 7 mm -Will offset the inherent weakness of FDL transfer by reducing th Sagittal T2-weighted FSE fat-suppressed image shows the angle between the posterior cruciate ligament and the plane of the tibial plateau less than 107° Fig. 1.11 Buckled course of the posterior cruciate ligament (PCL) as an indirect sign of complete anterior cruciate ligament (ACL) in a 26 year old male The posterior malleolus is easier to see on the lateral view. If there are only two malleoli fractured, it is a bi-mal ankle fracture. If the lateral mal is fractured, but there is no medial mal fracture it is a bi-mal equivalent (deltoid ligament is not intact, and it acts like a true bi-ma
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.
Anterior tibiofibular ligament sprain Lateral short oblique fibula fracture anteroinferior to posterosuperior Posterior tibiofibular ligament rupture or avulsion of posterior malleolus Medial malleolus transverse fracture or disruption of deltoid ligament. 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

A ligamentum teres tear or rupture can lead to severe pain. This ligament connects the ball of the hip joint (femoral head) to the hip socket (acetabulum) Posterior Malleolus Fracture: Radiographic Evaluation Indication for fixation: > 25% joint surface on lateral Problem: Fragment size hard to determine on lateral view - Reason: Fracture orientation not purely in coronal plane •Nearly always associated with the pull of the posterior tib-fib ligament - larger laterally than mediall
The middle part of the ligament lies just posterior to the subscapularis; it may blend together with fibers of the subscapularis muscle. It can vary in size and shape but is usually thin [3, 4]. It may appear thickened and cordlike (Figure 22), as in the Buford complex (Figures 12 and 15), or completely absent in 30% of healthy subjects MB BULLETS Step 1 For 1st and 2nd Year Med Students. To provide adequate treatment for patients with oblique fractures of the fibula, the extent of ligamentous damage must first be determined. Distal Fibula Fracture Orthobullets. Symptoms. Neck.

Regions of the lower limb illustrated by anterior and posterior views of the hip, thigh, knee, leg, ankle, tarsus, and toes of the feet allowing to view regions such as the gluteal region the femoral triangle (scarpa), the popliteal fossa, the sural region (calf), the ankle region, the dorsum of the foot and plantar region Meniscal ramp lesions are more frequently associated with anterior cruciate ligament (ACL) injuries than previously recognized. Some authors suggest that this entity results from disruption of the meniscotibial ligaments of the posterior horn of the medial meniscus, whereas others support the idea that it is created by a tear of the peripheral attachment of the posterior horn of the medial. Anterior-posterior (AP), lateral, and oblique views should be performed. The absolute sagittal diameter of the spinal canal is measured from the posterior aspect of the mid-vertebral body to the spinolaminar line. A reduction to 13 mm or less at C3-C7, or a ratio of canal diameter to mid-vertebral body diameter of 0.8 or less is stenotic Ligament damage may be inferred by an abnormal configuration of the ankle fork. The syndesmosis consists of the anterior/posterior tibiofibular ligament and the interosseous ligament (fig. 15). Figure 15.
