Definition. The fibular diaphysis lesions included 22 intertubercular lesions (16.7%), 66 supratubercular (50%), 14 medial-diaphyseal (10.6%), 10 multifocal (6.6%), and 20 fractures located at the neck of the fibula (15.2%). Diaphysis is the anatomical name for the shaft of a long bone, which is differentiated from the epiphyses, the ends of the bone. Fibular Strut. Treatment depends on the type of distal fibula fracture which is a reflection of the severity of the fracture and the surrounding ligamentous structures. Large grafts are comprised of the diaphysis and epiphysis of long bones. measure clear space 1 cm above joint Fibula Shaft. Anatomy. Fractures of the fibula are usually caused by direct trauma, twisting, avulsion, or rotational forces and are often characterized by associated injuries with the tibia because of the interosseus membrane which forces the two bones to move as a unit. Fibula definition is - the outer and usually smaller of the two bones between the knee and ankle in the hind or lower limbs of vertebrates. The majority of injuries are relatively simple avulsion injuries from the fibular pole and only require immobilization with a cast. Fibular shaft fractures occur in the mid-portion of the fibula after an injury such as a direct blow to the area; A fibula fracture can be due to many different injuries. The fibula is a bone of the leg which, together with the tibia, forms the bony lower leg.Firmly attached to the tibia, the fibula forms the articular surfaces for the upper ankle.. 2 Anatomy 2.1 Corpus fibulae (fibular shaft). A diaphyseal fracture is a bone break that occurs along the shaft of a long bone like the femur in the thigh or the ulna in the forearm. The fibula (also known as calf bone, Latin: (os) fibula) is the smaller of the bones forming the lower leg. Fibula, Ulna, Radius Grafts. The fibula is a slender bone that lies posterolaterally to the tibia. In a randomized controlled trial of 114 patients from Turkey with isolated tibial diaphyseal fractures without fibular fracture who were treated with either plating or intramedullary nailing, Saied et al found that plates yielded a better chance of union in these fractures where the fibula was intact. More commonly, fibular shaft fractures occur in association with fractures of the tibia or ankle injury. 1 Definition. fixation usually not required when fibula fracture within 4.5 cm of plafond; up to 25% of tibial shaft fractures will have ankle injury (highest rate with distal 1/3 spiral fractures) Evaluation . www.futura-sciences.us/dico/d/medical-science-fibula-50006222 The fibula belongs to long bones, and it has three parts: a diaphysis or shaft, and two epiphyses or extremities - proximal and distal. It is located on the lateral side next to the tibia. Segments are subdivided into: whole, proximal, and distal. Fibular Wedges.
