When a bone fractures, the fragments lose their alignment in the form of displacement or angulation. For the fractured bone to heal without any deformity the bony fragments must be re-aligned to their normal anatomical position. Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement.
Elbow fractures are any broken bone in or near the elbow joint and include olecranon fractures, supracondylar humerus fractures and radial head fractures. [1] The elbow joint is formed by three different bones: the ulna, radius, and humerus that permit the joint to move like a hinge and allow a person to straighten and bend their arm and these bones are connected by tendons, ligaments, and ...
Olecranon fractures are rare in children, constituting only 5 to 7% of all elbow fractures. This is because in early life, olecranon is thick, short and much stronger than the lower extremity of the humerus. [5] However, olecranon fractures are a common injury in adults. This is partly due to its exposed position on the point of the elbow.
The acute rupture occurs in collisions when the elbow is in flexion such as that in a wrestling match or a tackle in football. The ulnar collateral ligament distributes over fifty percent of the medial support of the elbow. [16] [17] This can result in an UCL injury or a dislocated elbow causing severe damage to the elbow and the radioulnar joints.
In medicine, the Ilizarov apparatus is a type of external fixation apparatus used in orthopedic surgery to lengthen or to reshape the damaged bones of an arm or a leg; used as a limb-sparing technique for treating complex fractures and open bone fractures; and used to treat an infected non-union of bones, which cannot be surgically resolved.
Radial head fractures are a common type of elbow fracture that typically occurs after a fall on an outstretched arm. [1] They account for approximately one third of all elbow fractures and are frequently associated with other injuries of the elbow. [2] [3] Radial head fractures are diagnosed by a clinical assessment and medical imaging.
Supracondylar humerus fractures is commonly found in children between 5 and 7 years (90% of the cases), after the clavicle and forearm fractures. It is more often occurs in males, accounting of 16% of all pediatric fractures and 60% of all paediatric elbow fractures. The mechanism of injury is most commonly due to fall on an outstretch hand.

A harvested tendon, such as the palmaris tendon [11] from the forearm of the same or opposite elbow, the patellar tendon, hamstring, toe extensor or a donor's tendon , is then woven in a figure-eight pattern through the holes and anchored. [10] The ulnar nerve is usually moved to prevent pain, as scar tissue can apply pressure to the nerve. [11]
