Medical Reports: Wrist and Fingers

Anatomy of the Wrist and Fingers

The wrist and fingers are complex and highly flexible parts of our body, enabling a wide range of everyday activities. To better understand how they work and how they can be prone to injuries, it is important to delve deeper into their anatomy.

Wrist

The wrist consists of eight carpal (wrist) bones, arranged in two rows of four bones each. The proximal row includes the scaphoid, lunate, triquetrum, and pisiform bones, while the distal row consists of the trapezium, trapezoid, capitate, and hamate bones. These bones work together as a system that allows the wrist to move in various directions, including flexion, extension, radial deviation (movement toward the thumb), and ulnar deviation (movement toward the pinky finger). The carpal bones are connected by joints and ligaments, providing stability while allowing movement. 

Fingers

The fingers of the hand consist of three types of bones: proximal, middle, and distal phalanges. The thumb is an exception, as it has only two phalanges: proximal and distal. These bones are connected by several joints: the metacarpophalangeal joint (MCP) at the base of each finger, the proximal interphalangeal joints (PIP) in the middle of the fingers, and the distal interphalangeal joints (DIP) at the fingertips, except for the thumb, which has only one interphalangeal joint. The muscles responsible for finger movement are divided into those originating from the forearm and those located directly in the palm. The extensors, which enable finger extension, run along the back of the hand, while the flexors, which enable finger flexion, are located on the opposite side. 

Due to their complex and precisely coordinated anatomy, the wrist and fingers enable a wide range of movements, from gross motor actions to very fine movements such as typing or writing. 

Common Problems and Conditions of the Wrist and Fingers

The wrist and fingers are particularly susceptible to various injuries and chronic conditions due to their complex structure and vital role in daily activities. Below is a detailed description of the most common issues affecting these body parts.

Injuries

• Sprains: Wrist or finger sprains are common and usually occur due to unexpected movement or a fall where the hand is used to absorb the impact. Sprains can affect the ligaments that support the joints, causing pain, swelling, and limited mobility. 
• Fractures: Fractures can result from direct impacts or falls onto an outstretched hand. A wrist fracture, particularly a scaphoid fracture, is one of the most common injuries. Fingers are also prone to fractures, especially during sports activities.
• Carpal Tunnel Syndrome: This condition is caused by pressure on the median nerve in the wrist, which can result from various factors, including repetitive movements, hormonal changes, swelling, or anatomical changes. Symptoms include pain, numbness, tingling, and weakness in the fingers and hand.

Chronic Conditions

• Arthritis: Osteoarthritis is common among older adults and occurs due to the wear and tear of joint cartilage in the wrist and fingers, leading to pain and stiffness. Rheumatoid arthritis is an autoimmune condition that often affects the wrists and fingers, causing inflammation, swelling, and joint deformities, which can significantly limit mobility.
• Tendonitis: Inflammation of the tendons, which can occur due to overuse or chronic strain, is common among athletes and individuals performing repetitive hand activities. Examples include de Quervain's tendonitis, which affects the tendons on the thumb side, and finger tendonitis, which causes pain when bending the fingers.
• Ganglion Cysts: These cysts are painless but can become problematic if they start pressing on surrounding nerves or restricting movement. 

Less Common Issues

• Dupuytren's Contracture: This condition affects the fascia - the connective tissue beneath the skin of the palm and fingers, leading to permanent flexion of the fingers, particularly the thumb and ring finger.
• Tenosynovitis: An inflammation of the tendon sheath, which can cause pain, swelling, and a sensation of friction during tendon movement.

Understanding these common issues helps in the early identification of symptoms and seeking appropriate treatment to prevent the condition from worsening and maintain hand functionality. Prevention, such as proper ergonomics, regular breaks during repetitive tasks, and strengthening exercises, plays a crucial role in protecting the health of the wrist and fingers.

Common Terms in Medical Reports for the Wrist and Fingers

Medical reports often contain technical terms, which can be difficult for laypersons to understand. This section explains some common terms that may appear in such reports.

• Carpal Tunnel: This is a narrow passage in the wrist through which the median nerve and tendons pass. Conditions like carpal tunnel syndrome occur when pressure is placed on the median nerve, causing pain, numbness, and tingling in the hand.
• Tendonitis: This is an inflammation of the tendon, often affecting the hands and wrists due to repetitive motions. Symptoms include pain, tenderness, and limited mobility.
• Osteoarthritis: This is a type of arthritis caused by joint wear and tear. In reports, it may be referred to as a degenerative joint disease, meaning the gradual deterioration of cartilage in the joints.
• Fracture: This is the medical term for a broken bone. Reports may specify the type of fracture, such as a scaphoid fracture, which is a common wrist injury.
• Dislocation: This is a condition where the bones in a joint are not properly aligned. Dislocations of the wrist and fingers are common due to sports injuries or falls.
• Ganglion Cyst: This is an abnormal swelling that most commonly appears on the wrist or fingers.
• Tenosynovitis: This is an inflammation of the sheath surrounding a tendon. De Quervain's tenosynovitis is a specific type affecting the tendons on the thumb side of the wrist.
• Radiography: This is a diagnostic procedure, often referred to as an X-ray, used to visualize the bones and joints in the wrist and fingers.
• MRI (Magnetic Resonance Imaging): This is a type of imaging test that uses powerful magnetic fields and radio waves to create detailed images of soft tissues such as muscles, ligaments, and tendons in the wrist and fingers.
• Radioulnar Dissociation: This is a condition where the radius and ulna, two bones in the forearm, move abnormally or are not properly aligned within the wrist joint. It can cause wrist instability, pain, and limited function. Radioulnar dissociation is often the result of trauma or wrist injuries.

Understanding these terms can help individuals better comprehend their medical reports and enable more effective communication with healthcare professionals. 

Diagnostic Procedures for Wrist and Finger Problems

Diagnostic procedures play a crucial role in accurately determining the causes of pain and issues in the wrist and fingers. The use of appropriate diagnostic technology is essential for guiding effective treatment. Below are detailed descriptions of commonly used methods.

• X-rays (Radiography): X-rays are the first line of diagnostics for identifying wrist and finger problems, especially when fractures or other structural abnormalities are suspected. This method is effective in visualizing the condition of the bones, including fractures, cracks, and possible signs of wear. 
• Magnetic Resonance Imaging (MRI): MRI is highly effective for visualizing soft tissues, including ligaments, muscles, nerves, and tendons. This method uses strong magnetic fields and radio waves to create detailed images of internal structures. MRI is particularly useful for diagnosing issues not visible on X-rays, such as soft tissue injuries, inflammatory processes, and abnormalities in the tissues.
• Computed Tomography (CT): CT combines multiple X-ray images taken from different angles to create cross-sectional images of the body. This method is more effective than standard X-rays for visualizing fine bone structures and is especially useful for complex fractures. CT is also important for surgical planning, as it provides surgeons with a better understanding of anatomical structures.
• Ultrasound: Ultrasound is another useful diagnostic method that uses sound waves to create images of soft tissues such as tendons, muscles, and sometimes nerves. This method is particularly helpful for dynamically evaluating tissue conditions, as it allows real-time visualization of structures during movement. 
• Nerve Conduction Studies and Electromyography (EMG): These are used to assess the function of muscles and nerves, particularly when neurological causes of symptoms in the hands are suspected. Electromyography measures the electrical activity of muscles, while nerve conduction studies evaluate how quickly nerves transmit electrical signals.

Each of these diagnostic procedures has its advantages and limitations, so selecting the right method depends on the specific symptoms and the patient's medical history. Timely and accurate diagnosis is crucial for the successful treatment of wrist and finger issues. It is important to consult a healthcare professional at the first signs of symptoms.

Treatment and Rehabilitation of Wrist and Finger Problems

Effectively managing injuries or chronic conditions of the wrist and fingers requires integrating various therapeutic approaches. Tailored treatment plans, including both conservative methods and advanced interventions, are essential for optimal recovery.

Conservative Treatment Methods

• Rest: Rest is essential to reduce stress on the injured wrist or fingers, prevent further injury, and promote faster healing. Avoid activities that cause pain in the affected area. 
• Cold Therapy: Applying cold compresses to the injured area several times a day helps reduce swelling and relieve pain. Cold therapy is especially beneficial in the first few days after injury.
• Compression: Using elastic bandages or medical braces supports the injured tissue and helps minimize swelling. 
• Elevation: Raising the affected wrist or fingers above heart level reduces swelling.

Physical Therapy

Physical therapy is vital for restoring strength, mobility, and functionality after an injury. Therapeutic exercises supervised by a physiotherapist include stretching and strengthening exercises. Therapy may also include:

• Manual Techniques: Massage and joint mobilization to improve mobility and relieve pain.
• Physical Modalities: Use of ultrasound, TENS (transcutaneous electrical nerve stimulation), and heat packs to improve circulation and reduce pain.
• Kinesiotherapy: Specific exercises to increase the range of motion and strengthen the muscles around the injured joint.

Use of Braces

Braces are often prescribed to stabilize the wrist or fingers during healing. 

• Temporary Braces: For use during the day when the hands are active, to prevent further injuries.
• Night Braces: Slightly firmer braces for nighttime use, helping maintain the correct position of the wrist or fingers during sleep.

Surgical Interventions

In cases where conservative methods do not yield satisfactory results or in severe injuries such as complex fractures, significant ligament injuries, or chronic conditions like carpal tunnel syndrome, surgery may be required. Surgical interventions may include:

• Repair of damaged structures: Treatment of fractures, reconstruction of ligaments, or tendons.
• Removal of cysts or inflamed tissue: Procedures to relieve nerve pressure and improve functionality.
• Joint reconstruction: For severe forms of arthritis or other degenerative conditions.

A holistic approach to the treatment and rehabilitation of the wrist and fingers is essential to restore full function and prevent future issues. Collaboration between the patient, healthcare professionals, and physiotherapists is vital for achieving the best possible outcomes.
