Ulnar collateral ligament reconstruction, colloquially known as Tommy John surgery, is a surgical graft procedure where the ulnar collateral ligament in the medial elbow is replaced with either a tendon from elsewhere in the patient's body, or with one from a deceased donor.
However, if patients have a positive ulnar variance and focal wrist pathology, it’s possible to treat with an isolated ulnar-shortening osteotomy. In these patients the radial deformity is not treated. [5] The ulna is approached from the subcutaneous border. A plate is attached to the distal end of the ulna, to plan the osteotomy.
It is performed in cases of radial–ulnar joint pain and instability. [1] The styloid process and muscular attachments are left intact. [2] Weakness and instability can develop after the procedure. It is most appropriate for elderly patients with low physical demands. [3]
Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. [1] [2] [3] It was originally used to treat problems like unequal leg length, but since the 1980s is most commonly used to treat issues like hemifacial microsomia, micrognathism (chin so small it causes health problems), craniofrontonasal ...
Once the fragments are reduced, the reduction is maintained by application of casts, traction, or held by plates, screws, or other implants, which may in turn be external or internal.
Shortening of radial length more than 4mm is associated with wrist pain. [5] Ulnar variance - It is the vertical distance between a horizontal line parallel to the articular surface of the radius and another horizontal line drawn parallel to the articular surface of the ulnar head. Positive ulnar variance (ulna appears longer than radius ...
External fixation is a surgical treatment wherein Kirschner pins and wires are inserted and affixed into bone and then exit the body to be attached to an external apparatus composed of rings and threaded rods — the Ilizarov apparatus, the Taylor Spatial Frame, and the Octopod External Fixator — which immobilises the damaged limb to facilitate healing.

Gamekeeper's thumb and skier's thumb are two similar conditions, both of which involve insufficiency of the ulnar collateral ligament (UCL) of the thumb. The chief difference between these two conditions is that skier's thumb is generally considered to be an acute condition acquired after a fall or similar abduction injury to the metacarpophalangeal (MCP) joint of the thumb, whereas gamekeeper ...
