Posterior depression of the distal humerus is a type of fracture that occurs in the lower end of the humerus bone in the arm. The humerus is the long bone that runs from the shoulder to the elbow, and the distal end is the portion that is closest to the elbow. A posterior depression fracture is one in which the bone is fractured and the fragment is pushed inward towards the back of the arm.
Posterior depression fractures of the distal humerus are relatively rare and typically occur as a result of high-energy trauma, such as a car accident or a fall from a significant height. They may also occur in cases of osteoporosis, a condition in which the bones become weak and brittle due to a loss of bone density.
Symptoms of a posterior depression fracture of the distal humerus include pain, swelling, and difficulty moving the arm. The arm may also appear deformed or out of place. A posterior depression fracture is diagnosed through a physical examination, x-rays, or other imaging tests such as CT scans or MRIs.
Treatment for a posterior depression fracture of the distal humerus may vary depending on the severity of the injury. Non-surgical options may include the use of a splint or cast to immobilize the arm and allow the bone to heal. Physical therapy may also be recommended to help restore movement and strength to the arm. In more severe cases, surgery may be necessary to repair the fracture and restore the normal shape of the bone. This may involve using screws, plates, or other types of hardware to hold the bone in place while it heals.
Recovery from a posterior depression fracture of the distal humerus can take several weeks to several months, depending on the severity of the injury and the treatment chosen. Physical therapy and rehabilitation are important components of the recovery process and can help to restore function to the arm.
In conclusion, posterior depression fractures of the distal humerus are a type of injury that occurs in the lower end of the humerus bone in the arm. They are typically caused by high-energy trauma and may require surgical intervention to repair the fracture and restore the normal shape of the bone. With proper treatment and rehabilitation, it is possible to recover from this injury and regain full function of the arm.

The medial and lateral borders of the distal humerus form the medial and lateral supracondylar ridges. You should sleep upright, either in an arm chair, or sitting up in bed propped up on plenty of pillows. They work to adduct and medially, or internally, rotate the humerus. The posterior depression on the distal humerus is called the olecranon fossa. The humerus serves as an attachment to 13 muscles which contribute to the movements of the hand and elbow, and therefore the function of the upper limb. Then, if the capitulum lies on the left side of the bone, it is a left humerus.
Distal Region of Humerus The lower end of the humerus is the distal humerus, containing two joint-forming processes, the capitulum and the trochlea. This is where the the fourth and last rotator cuff muscle, the subscapularis, attaches. It forms the upper part of the elbow and is the spool around which the forearm bends and straightens. . Among the two, the medial is larger, extending more towards the elbow joint. It is sometimes referred to as the bicipital groove.
What are the common injuries and conditions associated with this bone? Despite this, the distal portion of the humerus also contains two other depressions, known as the coronoid and radial fossae. In elbow extension, the tip of the ulnar olecranon process lodges into this fossa. A fractured humerus or upper arm is extremely painful, and the patient may not be able to move their arm. It is also important for rotation of the forearm; that is, the ability to turn your hand palm up like accepting change from a cashier or palm down like typing or playing the piano. Nonsurgical Treatment Nonsurgical treatment may be recommended for stable fractures in which the pieces of bone are not out of place displaced. The proximal end of the ulna fits securely into this significant depression, that sits superior to the trochlea, when the arm is extended. Your doctor will apply a splint or sling to hold the elbow in place during healing.
Among the two ridges, the lateral supracondylar ridge is relatively roughened, providing the common origin site of the forearm extensor muscles. Orthopaedic Knowledge Online Journal 2015; 13 7. Repetition Repetition Repetition This one is fairly obvious, the more you go over something, the more likely you will remember it. It is more common with fractures that happen closer to the base of the bone. At the proximal end, most fractures are located at the surgical neck and are most common in the elderly, especially those with osteoporosis.

Bus A takes 25 minutes to complete its route once and bus B takes 35 minutes to complete its route once.
