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. ; surgical neck: A constriction below the tubercles of the greater tubercle and lesser tubercle. Fortunately, a combination of standard nonunion techniques with new plate designs and fixation … The ulna is a long bone in the forearm.   The top of the arm bone is called the proximal humerus, and the bottom of the bone is called the distal humerus. 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. Humerus fractures are generally divided into three types of injuries based on the location of the fracture. It will fracture here and this portion, the distal fragment will slip backwards and the proximal humerus, this proximal fragment will slip forward. 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. for more anatomy content please follow us and visit our website: www.anatomynote.com. However, a complete understanding of the fracture is difficult secondary to collapse of elbow anatomy caused by fracture displacement. Total elbow replacement (arthroplasty). This study defines the osseous anatomy and anatomic variability of the distal humerus using 3 … • 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. Distal humerus. 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. humerus, humeral shaft, and distal humerus. When viewed from an anterior or posterior position, the distal humerus appears to be shaped like a triangle. A humerus fracture is an injury to the bone of the upper arm that connects the shoulder to the elbow. The humerus begins proximally as a rounded head and joins the greater and lesser tubercles via the anatomical neck of the humerus. Humeral fractures can be categorized into three type of groups, depending on which part of the bone is broken. The humerus is the single bone of the upper arm. anatomy of the distal humerus is restored. 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. 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. (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. Majority of the distal humerus fractures are treated with the help of surgery. Distally, the ulna articulates with the radius, forming the distal radio-ulnar joint. ; capitulum: At the distal head of the humerus, it articulates with the radius of the forearm. These are severely disabling problems for the patient and a challenge for the treating physician. Functional Anatomy • The distal humerus angles forward - like a hockey stick! A proximal humerus fracture is when the humerus bone is broken at or near the top, near or at the shoulder. Humerus still occur sedation or anesthesia reduce and fix the articular block using screws.
