ABSTRACT: Joint injection of the wrist and hand region is a useful diagnostic and therapeutic tool for the family physician. In this article, the injection procedures for carpal tunnel syndrome, de Quervain's tenosynovitis, osteoarthritis of the first carpometacarpal joint, wrist ganglion cysts, and digital flexor tenosynovitis (trigger finger) are reviewed. Indications for carpal tunnel syndrome injection include median nerve compression resulting from osteoarthritis, rheumatoid arthritis, diabetes mellitus, hypothyroidism, repetitive use injury, and other traumatic injuries to the area. For the first carpometacarpal joint, injection may be used to treat pain secondary to osteoarthritis and rheumatoid arthritis. Pain associated with de Quervain's tenosynovitis is treated effectively by therapeutic injection. If complicated by pain or paresthesias, wrist ganglion cysts respond to aspiration and injection. Painful limitation of motion occurring in trigger fingers of patients with diabetes or rheumatoid arthritis also improves with injection. The proper technique, choice and quantity of pharmaceuticals, and appropriate follow-up are essential for effective outcomes.
ABSTRACT: Improper diagnosis and treatment of finger injuries can cause deformity and dysfunction over time. A basic understanding of the complex anatomy of the finger and of common tendon and ligament injury mechanisms can help physicians properly diagnose and treat finger injuries. Evaluation includes a general musculoskeletal examination as well as radiography (oblique, anteroposterior, and true lateral views). Splinting and taping are effective treatments for tendon and ligament injuries. Treatment should restrict the motion of injured structures while allowing uninjured joints to remain mobile. Although family physicians are usually the first to evaluate patients with finger injuries, it is important to recognize when a referral is needed to ensure optimal outcomes.
ABSTRACT: Family physicians often encounter patients with acute knee trauma. Radiographs of injured knees are commonly ordered, even though fractures are found in only 6 percent of such patients and emergency department physicians can usually discriminate clinically between fracture and nonfracture. Decision rules have been developed to reduce the unnecessary use of radiologic studies in patients with acute knee injury. The Ottawa knee rules and the Pittsburgh decision rules are the latest guidelines for the selective use of radiographs in knee trauma. Application of these rules may lead to a more efficient evaluation of knee injuries and a reduction in health costs without an increase in adverse outcomes.
ABSTRACT: Methods of preventing and treating knee injuries have changed with the rapid development and refinement of knee braces. Prophylactic knee braces are designed to protect uninjured knees from valgus stresses that could damage the medial collateral ligaments. However, no conclusive evidence supports their effectiveness, and they are not recommended for regular use. Functional knee braces are intended to stabilize knees during rotational and anteroposterior forces. They offer a useful adjunct to the treatment and rehabilitation of ligamentous knee injuries. Patellofemoral knee braces have been used to treat anterior knee disorders and offer moderate subjective improvement without significant disadvantages. Additional well-designed studies are needed to demonstrate objectively the benefits of all knee braces. Knee braces should be used in conjunction with a rehabilitation program that incorporates strength training, flexibility, activity modification and technique refinement.
