Clinical Concern

Chapter 99 describes indications, technique, and imaging findings of elbow arthrography. Elbow arthrography is selectively performed for MR arthrography (MRA), typically in younger patients for evaluation of ligamentous (ulnar or radial collateral ligaments) injuries and osteochondral lesions. Indications also include therapeutic injections. The posterior transtriceps approach is preferred when the clinical concern is for radial collateral ligament injury. Contrast should easily inject and disperse throughout the joint. Contrast opacifies the anterior (coronoid), posterior (olecranon), and periradial (annular) recesses, which are easily depicted on lateral radiograph. Complications are rare but include infection and bleeding.

Knee Arthrography

Chapter 102 describes indications, technique, and imaging findings of knee arthrography. Knee arthrography is selectively performed in clinical practice for MRA, typically in younger patients. Indications include evaluation for meniscal re-tear after prior repair, osteochondral injuries, and therapeutic injections (most commonly steroid). Extension of intraarticular contrast into the meniscal substance indicates a tear or re-tear. Abnormal course of the cruciate ligament fibers indicates a tear. Contrast undermines unstable osteochondral lesions and extends into the hyaline cartilage defects. Complications are rare but include infection and bleeding.

Medial Collateral Ligament Injury

Anterior elbow dislocation without periarticular fracture (simple dislocation) is an extremely rare injury and is usually caused by distraction or torsional forces. It is important to look for associated ligamentous and musculotendinous injuries in this pattern. We report an elderly patient who sustained simple anterior dislocation of the elbow and in whom successful closed reduction could be achieved. Reduction by closed method is possible if we know the exact mechanism of elbow injury. Despite the presence of medial collateral ligament injury, he was managed non-operatively and had full functional recovery. Checking for joint stability and collateral ligaments after reduction and getting additional radiological investigations help in better treatment planning. Early protected active mobilisation should be initiated to achieve better functional results.

Thumb Metacarpophalangeal Joint

Five cases of chronic instability of the radial collateral ligament of the thumb metacarpophalangeal joint are presented. All patients were treated using the Mitek suture anchor to reattach the avulsed ligament to bone in its anatomical position. Tendon advancement or graft reinforcement was not used in conjunction with the repair. A stable thumb metacarpophalangeal joint was achieved in each case with no recurrent instability or pain found within 9 months of follow-up. Postoperatively, each patient exhibited a full return to activities of daily living within 2 to 3.5 months. Grip and pinch strength and range of motion were nearly the same as in the uninjured hand. We recommend the Mitek suture anchor as a simple and effective method of repairing the chronic radial collateral ligament injury. The importance of correct anatomical placement of the anchor is stressed, and guidelines for this are discussed.

Radial Side

Human cadaver thumbs were tested to evaluate stability of the radial side of the MP joint. The contributions of the dorsal capsule, radial collateral ligament, accessory collateral ligament, and volar plate were examined with the joint in 0° and 30° of flexion. At 0° flexion, the average joint angulation increased 4° following isolated radial collateral ligament transection and 6° following isolated accessory collateral ligament transection. Release of both the accessory and radial collateral ligaments produced marked instability with joint angulation of at least 46° The accessory collateral ligament helped to stabilize the extended MP joint. There were no significant contributions to stability from the dorsal capsule and volar plate when the collateral ligaments were intact. In the laboratory setting, radial-side instability of the MP joint of the thumb requires transection of both the proper and accessory radial collateral ligaments.
