distal humerus anatomy

– When using the dorsolateral plate without lateral support, it is important to reduce and fix the articular block with Anatomy . The ulna is a long bone in the forearm. for more anatomy content please follow us and visit our website: www.anatomynote.com. The lateral trochlear ridge is the key to analyzing humeral condyle fractures. anatomy of the distal humerus is restored. A distal humerus fracture occurs when there is a break anywhere within the distal region (lower end) of the humerus. 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. Ensure that the Kirschner wires or reduction forceps will not interfere with subsequent plate placement. In addition to the areas mentioned above, the humerus is made up of other parts, too. Humerus fractures are generally divided into three types of injuries based on the location of the fracture. Arms were dissected and radiopaque wires attached to the radial nerve in the distal part of the upper arm. ; capitulum: At the distal head of the humerus, it articulates with the radius of the forearm. A postoperative radiograph is shown in Figure A. Humeral fractures can be categorized into three type of groups, depending on which part of the bone is broken. Anatomy of the Humerus Bone Proximal Region A humerus fracture is an injury to the bone of the upper arm that connects the shoulder to the elbow. Functional Anatomy • The distal humerus angles forward - like a hockey stick! 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. 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. Open subtypes (2) Courses and events. 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. We are pleased to provide you with the picture named Distal End Of Right Humerus.We hope this picture Distal End Of Right Humerus can help you study and research. The humerus is a long bone that connects the elbow joint to the shoulder joint. A humerus fracture is a break in the large bone of your upper arm. However, a complete understanding of the fracture is difficult secondary to collapse of elbow anatomy caused by fracture displacement. These are severely disabling problems for the patient and a challenge for the treating physician. This fracture is generally caused due to a high energy impact. ; trochlea: At the distal head of the humerus, it articulates with the ulna of the forearm. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint. A proximal humerus fracture is when the humerus bone is broken at or near the top, near or at the shoulder. It will fracture here and this portion, the distal fragment will slip backwards and the proximal humerus, this proximal fragment will slip forward. Majority of the distal humerus fractures are treated with the help of surgery. 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). Initial radiographs of the elbow and distal humerus invariably show the fracture. 2015 Nov;97-B(11):1539-45. doi: 10.1302/0301-620X.97B11.36071. Notes: – If necessary, reduce the articular block using independent screws. 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. The capitellotrochlear sulcus divides the capitellar and trochlear articular surfaces.   The top of the arm bone is called the proximal humerus, and the bottom of the bone is called the distal humerus. Anatomy, Patient examination 2; Compartment syndrome, Timing of treatment 2; Essential concepts of pediatric fracture care 10; Metaphyseal. 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. ; surgical neck: A constriction below the tubercles of the greater tubercle and lesser tubercle. humerus: The bone of the upper arm. 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. 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. Fortunately, a combination of standard nonunion techniques with new plate designs and fixation … Humerus Anatomy : Bony Landmarks & Muscle Attachment. 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. Anatomynote.com found Distal End Of Right Humerus from plenty of anatomical pictures on the internet. However, nonunions of the distal humerus still occur. Let’s explore some of these. 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. 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 many cases, adequate radiographs may only be obtainable while patient is in traction and under intravenous sedation or anesthesia. 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. When viewed from an anterior or posterior position, the distal humerus appears to be shaped like a triangle. This study defines the osseous anatomy and anatomic variability of the distal humerus using 3 … Distal humerus. Key Terms. Gross anatomy Osteology. Epiphyseal. The humerus begins proximally as a rounded head and joins the greater and lesser tubercles via the anatomical neck of the humerus. The top of the bone is part of the shoulder joint and the bottom is part of the elbow joint. The humerus is the single bone of the upper arm. 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). J Bone Joint Surg 82B:643–645, 2000 CrossRef Google Scholar (OBQ09.138) A 33-year-old male sustains a distal humerus fracture and is treated with open reduction and internal fixation of the distal humerus with olecranon osteotomy.
