Sauve Kapandji Procedure

Last Updated on November 16, 2018

Sauve Kapandji procedure is a procedure which involves removal of about 10 mm of ulna proximal to distal radio ulnar joint and fixing the distal fragment of ulna to radius by means of screw. Sauve Kapandji procedure aims at creating a new joint at the level where ulna is cut and serves two purposes. First , the procedure unloads the ulnar bone so that there is more force is transmitted to the radius instead of the triangular fibrocartilage. Secondly, Sauve Kapandji procedure at the same time provides a distal stabilization.

The image below illustrates the point well.

The procedure is contraindicated in unstable radioulnar joint or radioulnar joint dislocation.

Technique of Sauve Kapandji Procedure

An incision is made on the medial aspect beginning 5 cm above the ulnar head and ending distal to the ulnar head.
Ulnar neck and proximal aspect of ulnar head are exposed after dissection of the overlying tissue.
A kwire is put from ulna to radius in transverse direction for the purpose of fixing ulnar head to radius .
Using saw , ulna is cut just proximal to the flare of the ulnar head and a second cut is made 15 mm proximal to the first cut. If the saw is not available, multiple drill holes are made and then osteotomy is completed using osteotomes.
The ulnar segment is removed.
The distal ulnar fragment is lifted and radiounlar joint articular cartilage is removed
Ulnar head held is applied to the radius with a 4.0mm cancellous screws after drilling and tapping.
Pronator quadratus muscle is mobilized into the defect so created and anchored to the dorsal side of the ulnar stump.

Complications

Distal ulnar instability can occur
Reactive bone can form. This can result in limitation of the motion of the wrist
Radio-ulnar impingement can occur

Surgery in Spinal Tuberculosis

Surgery in spinal tuberculosis is considered in the patients where the disease is not responding to the drug treatment, rest and other conservative measures. The aims of treatment of tuberculosis of the spine are: Control and cure of the existing active systemic and local infection and prevent its further spread. Achieving the stability of the […]

Intraarticular Fractures Principles and Management

Intraarticular fractures are the fractures where the fracture line crosses into the surface of a joint resulting in some degree of cartilage damage. The fractures can vary from hairline fractures to displaced fractures. Intraarticular fractures ideally should be reduced anatomically and fixed securely so that early joint movement can be allowed. Where this cannot be […]

Pronator Syndrome or Pronator Teres Syndrome

Pronator syndrome is a compressive neuropathy of the median nerve at the level of the elbow. The median nerve, one of the three major nerves of the upper limb mainly supplies the hand and is also known as the eye of the hand. Pronator syndrome or pronator teres syndrome results in a predominantly sensory alteration […]

Heel Spur – Causes, Symptoms and Treatment

A heel spur is a small bony outgrowth or osteophyte on the underside of the heel. The heel spur is generally seen in middle-aged persons but can be found in other age groups too. The heel spur is commonly believed to be a cause of heel pain which is not true as heel spur is […]

Tendinopathy or Tendinosis or Tendonitis – Symptoms and Treatment

Tendinopathy refers to conditions affecting the tendons which cause pain, swelling, or decreased function. It may include tendonitis or tendinosis. Chronic tendinopathy can lead to weakening of the tendon and subsequent rupture. Middle-aged adults are most susceptible to the development of tendinopathy. Tendons transmit mechanical loads and it is thought to be a major causative […]

Posterior Cruciate Ligament injury or PCL Injury

Posterior cruciate ligament injury or PCL injury is less common than the anterior cruciate ligament injury. A posterior cruciate ligament tear may result in disability ranging from no impairment to severe impairment. The primary function of the PCL is to prevent posterior translation of the tibia on the femur. The posterior cruciate ligament is also important […]

Pyogenic Vertebral osteomyelitis Presentation and Treatment

Pyogenic vertebral osteomyelitis is a type of spinal infection which may result from direct trauma, the spread of infection from adjacent structures or hematogenous spread from the distant focus of infection. It can have devastating complications if untreated which could be a pathological fracture, epidural infection, and compression of the neural structures. Vertebral osteomyelitis is […]
