The lateral surface of the talus is triangular, smooth and concave for articulation with the lateral malleolus. 3. The medial surface is covered by comma-shaped facets for articulation with medial malleolus and distally the surface contains numerous vascular foramina. The human lungs are a pair of spongy organs within the thoracic cavity that facilitate gaseous exchange. The talus is the 2nd most commonly fractured tarsal bone (after the calcaneus).

The deltoid and sinus tarsi vessels provided significant minor sources of vascularity. Description. a. Femoral a. b. Interruption of the blood supply causes non-union and delayed union.There are 3 types of fractures at the proximal 5th metatarsal.The fracture in zone-1 is called tuberosity avulsion fracture, in zone-2 Jones fracture and that in zone-3 stress fracture.It is called Jones fracture when it occurs at the level of articulation of the 4th and 5th metatarsals.Treatment of Jones fracture is non weight bearing with cast or intramedullary screw fixation,the later being the majority choice and it is usually done in athletes and active individuals.If the fracture occurs distal to the 4th-5th metatarsal articulation, the fracture occurs mostly due to stress and wont heal very well without some form of fixation.If the fracture occurs in the rich area of the tuberosity which is proximal,then this fracture will heal(pseudo-Jones fracture).Non-union of fractures in zone-2 occur in upto 30% of cases.In zone-3 fractures, always check the foot for cavovarus deformity which can be very subtle. LUPOMAX has less vegetative matter compared to regular hop pellets so you get hop flavors that are bigger, bolder, and brighter! Scaphoid fractures can lead to non-union and avascular necrosis due to interruption of its blood supply. The blood supply to the talus is can be seriously compromised by a fracture-dislocation scenario. 2022 This creates the subtalar joint which provides shock absorption and facilitates the movements of inversion and eversion. Within the tarsus, it articulates with the calcaneus below and the navicular in front within the talocalcaneonavicular joint. Navicular fractures are always treated initially with a non-weight bearing cast. Circumflex artery: Winds around the left margin of the heart in the atrioventricular groove. Branches of the dorsalis pedis artery supply the dorsum of the navicular bone while the medial plantar branch of the posterior tibial artery supplies the plantar surface of the bone.The navicular tuberosity receives its blood supply from an anastomosis between these 2 vessels.The area where a stress fracture may occur is avascular which for the navicular bone is the central 1/3rd.There is a risk for developing non-union, delayed union and AVN when stress fractures occur in this area of the navicular bone. B. D. E. pectineus adductor longus iliacus psoas adductor brevis The femoral ring. They are a part of the respiratory system, which also includes the nose, nasal sinuses, mouth, pharynx, larynx, and trachea.

Last reviewed: November 30, 2022 Avascular necrosis (AVN) or osteonecrosis is defined as a disease resulting from temporary or permanent loss of the blood supply to bone ().Bone without blood supply and nourishment will necrose, causing the bone to collapse ().This process is often very painful and debilitating, particularly in the case of the talus since it supports both the ankle and subtalar joints (STJs) (Fig. It may also cause delay in healing of the bone or non-union of the fractures.Fractures in these areas usually result from trauma or stress related injuries.Speaking about the talus first,the most important blood supply comes from the artery of the tarsal canal.The artery of the tarsal canal arises from the posterior tibial artery.The deltoid branch also arises from the posterior tibial artery.It is essential to be aware that the deltoid branch of the artery of the tarsal canal is the only remaining artery in displaced fractures of the talar neck.Fracture of the talar neck will interrupt the blood supply and cause non-union of the fracture or Avascular Necrosis of bone.The more displacement of the fracture, the more likely that the fracture will develop non-union and the bone will develop avascular necrosis.The Hawkins sign is a subchondral radiolucent line that is seen in the dome of the talus on X-rays.It is more commonly seen on the medial side and on the mortise view.The Hawkins sign is usually seen at 6 weeks after injury.This means that there is resorption of the subchondral bone because there is vascularity. a. External iliac a. c. Popliteal a.d. Anterior tibial a. Reporting began in 1992. For the humeral head, there are 2 important arteries which are the anterior and posterior humeral circumflex arteries.The arcuate artery is still one of the primary blood supply to the humeral head.However,recent studies suggest that the posterior humeral circumflex artery provides the main blood supply of the humeral head and it is a controversial topic.
