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. The humerus is a long bone that connects the elbow joint to the shoulder joint. The broken pieces of bone may line up straight or may be far out of place (displaced fracture). Humerus fractures are generally divided into three types of injuries based on the location of the fracture. Humeral fractures can be categorized into three type of groups, depending on which part of the bone is broken. A humerus fracture is a break in the large bone of your upper arm.

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. The top of the bone is part of the shoulder joint and the bottom is part of the elbow joint. 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. anatomy of the distal articular surface of the humerus. What most commonly happens is that the distal fragment displaces backwards. The capitellotrochlear sulcus divides the capitellar and trochlear articular surfaces. The bone can crack just slightly or break into many pieces (comminuted fracture). The surgical neck is found just inferior to the tubercles where the shaft begins. Initial radiographs of the elbow and distal humerus invariably show the fracture. The humerus is the site where many muscles and ligaments are attached, resulting in multiple raised roughening on the bony surface area. Distal humerus. There are indications, ad-vantages, and disadvantages to the classic surgical exposures to the hu-merusaswellastosomeofthemost recently developed more extensile exposures.Ofparamountimportance is the neurovascular anatomy of the brachium (Table 1). A distal humerus fracture occurs when there is a break anywhere within the distal region (lower end) of the humerus. – When using the dorsolateral plate without lateral support, it is important to reduce and fix the articular block with Proximally, the circumflex humeral vessels and the ; surgical neck: A constriction below the tubercles of the greater tubercle and lesser tubercle. 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. Humerus Anatomy : Bony Landmarks & Muscle Attachment. The effect of the anatomy of the distal humerus and proximal ulna on the positioning of the components in total elbow arthroplasty Bone Joint J. However, a complete understanding of the fracture is difficult secondary to collapse of elbow anatomy caused by fracture displacement. Fortunately, a combination of standard nonunion techniques with new plate designs and fixation … 2. Digital radiographs were obtained to determine the course of the radial nerve in the distal 20 cm of the humerus in relation to bony landmarks; medial epicondyle and capitellum-trochlea projection (CCT). Notes: – If necessary, reduce the articular block using independent screws. Total elbow replacement (arthroplasty). The surgical neck is a common site for fractures (hence its name), while fractures of the anatomical neck are rare.. Anatomynote.com found Distal End Of Right Humerus from plenty of anatomical pictures on the internet. There are several types of humerus fractures, depending on the location of the break. Let’s explore some of these. Anatomy, Patient examination 2; Compartment syndrome, Timing of treatment 2; Essential concepts of pediatric fracture care 10; Metaphyseal. • Lateral decubitus positioning during ORIF facilitates reconstruction • The trochlear axis is 3-8 degrees externally rotated – (Least important to worry about if cartilage reconstructed) – Reason it is difficult to get a true lateral radiograph 35-40 Deg. Background: The optimal articular shape for distal humeral hemiarthroplasty has not been defined because of a paucity of data quantifying the morphology of the normal distal humerus. The humerus begins proximally as a rounded head and joins the greater and lesser tubercles via the anatomical neck of the humerus. Gross anatomy Osteology. 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. In Type I fractures, the lateral trochlear ridge remains with the intact condyle, providing medial to lateral elbow stability. This study defines the osseous anatomy and anatomic variability of the distal humerus using 3 … Distal Humerus Intercondylar Split. The humerus articulates proximal region by the scapula at the shoulder joint and radius and distal region with ulna at the elbow joint. In many cases, adequate radiographs may only be obtainable while patient is in traction and under intravenous sedation or anesthesia. This is the procedure most often used to treat distal humerus fractures. Going down the mountain vehicle's breaks failed and we crashed into a rock. Arms were dissected and radiopaque wires attached to the radial nerve in the distal part of the upper arm. Anatomy . Basic Anatomy The humerus is the long bone in the upper arm. The humerus bone is the long bone that is located between the shoulder and the elbow. Anatomy of the Humerus Bone Proximal Region There are also nerves, arteries, and veins going up and down along the bone. Distal: This is the lower area of your humerus that’s closest to your elbow. Ensure that the Kirschner wires or reduction forceps will not interfere with subsequent plate placement. These are severely disabling problems for the patient and a challenge for the treating physician. 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. Key Terms. 2015 Nov;97-B(11):1539-45. doi: 10.1302/0301-620X.97B11.36071. for more anatomy content please follow us and visit our website: www.anatomynote.com.

This is important to know because the brachial artery runs anterior to this bone. humerus: The bone of the upper arm. 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. This fracture is generally caused due to a high energy impact. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint. A postoperative radiograph is shown in Figure A. anatomy of the distal humerus is restored.   The top of the arm bone is called the proximal humerus, and the bottom of the bone is called the distal humerus. The ulna is a long bone in the forearm. humerus, humeral shaft, and distal humerus. 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). 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. 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.
