2. On this tutorial, I will do a brief introduction to the Humerus. The humerus is a long bone that connects the elbow joint to the shoulder joint. This is the procedure most often used to treat distal humerus fractures. There are a lot of muscles surrounding the humerus bone: the biceps and brachialis muscles in the front and the triceps muscle in the back. Functional Anatomy • The distal humerus angles forward - like a hockey stick! This study defines the osseous anatomy and anatomic variability of the distal humerus using 3 … – When using the dorsolateral plate without lateral support, it is important to reduce and fix the articular block with A physical therapist typically designs and supervises the therapy in consultation with the patient's orthopedic physician to make sure the therapy is appropriate for the patient's condition. Fortunately, a combination of standard nonunion techniques with new plate designs and fixation … Open reduction and internal fixation of distal humerus fractures is standard of care with good to excellent outcome for most patients. J Bone Joint Surg 82B:643–645, 2000 CrossRef Google Scholar Open subtypes (2) Courses and events. The lateral trochlear ridge is the key to analyzing humeral condyle fractures. A proximal humerus fracture is when the humerus bone is broken at or near the top, near or at the shoulder. In the coronal plane, the distal humerus is of triangular shape, formed by the medial and lateral columns linked by the articular segment as illustrated in Fig. http://www.interactive-biology.com - When looking at the bones of the arm and forearm, the first bone we need to look at is the distal humerus. Going down the mountain vehicle's breaks failed and we crashed into a rock. At the distal or elbow side, the capitulum process articulates with the head of the radius and the trochlea process articulates with the trochlear notch of the ulna. ; capitulum: At the distal head of the humerus, it articulates with the radius of the forearm. Gross anatomy Osteology. 13-E/4.1 Epi-/metaphyseal simple, SH IV. Arms were dissected and radiopaque wires attached to the radial nerve in the distal part of the upper arm. The humerus is described as having a proximal region, shaft, and distal region. Anatomynote.com found Distal End Of Right Humerus from plenty of anatomical pictures on the internet. humerus: The bone of the upper arm. The broken pieces of bone may line up straight or may be far out of place (displaced fracture). During the procedure, the bone fragments are first repositioned (reduced) into their normal alignment and then held in place with plates and screws attached to the outside of the bone. Humerus Anatomy : Bony Landmarks & Muscle Attachment. Total elbow replacement (arthroplasty). We sought to reexplore the anatomy of the lateral arm flap, the radial collateral artery (RCA) and its blood supply to the lateral, distal humerus with the goal of defining the clinically relevant vascular anatomy of the region and better defining its role as a free, vascularized bone graft. Notes: – If necessary, reduce the articular block using independent screws. ; trochlea: At the distal head of the humerus, it articulates with the ulna of the forearm. Proximally, the circumflex humeral vessels and the Let’s explore some of these. This fracture is generally caused due to a high energy impact. The surgical neck is found just inferior to the tubercles where the shaft begins. Distal: This is the lower area of your humerus that’s closest to your elbow. Key Terms. Humerus fracture rehabilitation is a course of therapy to help a patient recover from a fracture of the upper arm bone, and to prevent problems with the shoulder and upper arm in the future. Distal Humerus Intercondylar Split. The difficulty in treating complex distal humerus fractures lies in the unique and specific anatomy of the distal humerus, which allows it to articulate freely with the radius and ulna. However, a complete understanding of the fracture is difficult secondary to collapse of elbow anatomy caused by fracture displacement. The elbow is a trochoginglymoid joint; it has the capacity to flex and extend within the sagittal plane and also to rotate around a single axis. A humerus fracture is an injury to the bone of the upper arm that connects the shoulder to the elbow. In Type I fractures, the lateral trochlear ridge remains with the intact condyle, providing medial to lateral elbow stability. The humerus articulates proximal region by the scapula at the shoulder joint and radius and distal region with ulna at the elbow joint. ANATOMY AND CLASSIFICATION OF DISTAL HUMERAL FRACTURES. The bone can crack just slightly or break into many pieces (comminuted fracture). for more anatomy content please follow us and visit our website: www.anatomynote.com. The humerus bone is the long bone that is located between the shoulder and the elbow. Mohan N, Hunter JB, Colton CL: The posterolateral approach to the distal humerus for open reduction and internal fixation of fractures of the lateral condyle in children. In addition to the areas mentioned above, the humerus is made up of other parts, too. Distal humerus. Anatomy of Distal HumerusAnatomy of Distal Humerus -->The lower end of the humerus forms the condyles-->The lower end of the humerus forms the condyles which is expended from side to side, and has articularwhich is expended from side to side, and has articular and nonarticular parts.and nonarticular parts. The top of the bone is part of the shoulder joint and the bottom is part of the elbow joint. anatomy of the distal humerus is restored. Ensure that the Kirschner wires or reduction forceps will not interfere with subsequent plate placement. The surgical neck is a common site for fractures (hence its name), while fractures of the anatomical neck are rare.. The humerus is the site where many muscles and ligaments are attached, resulting in multiple raised roughening on the bony surface area. This is important to know because the brachial artery runs anterior to this bone. The humerus (/ ˈ h j uː m ər ə s /, plural: humeri) is a long bone in the arm that runs from the shoulder to the elbow.It connects the scapula and the two bones of the lower arm, the radius and ulna, and consists of three sections.The humeral upper extremity consists of a rounded head, a narrow neck, and two short processes (tubercles, sometimes called tuberosities). Humerus fractures are generally divided into three types of injuries based on the location of the fracture. What most commonly happens is that the distal fragment displaces backwards. However, nonunions of the distal humerus still occur. There are several types of humerus fractures, depending on the location of the break. Majority of the distal humerus fractures are treated with the help of surgery. It lies medially and parallel to the radius, the second of the forearm bones.The ulna acts as the stabilising bone, with the radius pivoting to produce movement.. Proximally, the ulna articulates with the humerus at the elbow joint.
