Wrist Injury: Understanding the Symptoms, Causes and Treatment

August 27, 2023

Overview of Wrist Injuries: Types, Symptoms, and Causes

The wrist is a complex joint that connects the hand to the forearm. It is responsible for a wide range of motions, including flexion, extension, abduction, and adduction. Due to its intricate structure and functionality, the wrist is susceptible to a variety of injuries.

Types of Wrist Injuries

  • Fractures: A fracture is a break in one or more of the bones that make up the wrist. The most common types of wrist fractures are distal radius fractures, which occur near the end of the radius bone, and scaphoid fractures, which occur in one of the small bones located near the thumb.
  • Dislocations: A dislocation occurs when the bones that make up a joint are forced out of their normal position. Dislocations of the wrist can occur at different locations, but are most common at the radiocarpal joint.
  • Sprains: A sprain is an injury to the ligaments that connect bones to one another. The most common type of sprain in the wrist is a ligamentous sprain of the radiocarpal joint.
  • Tendinitis: Tendinitis is inflammation of a tendon. In the wrist, tendinitis most commonly affects the tendons that attach to the thumb or the fingers.
  • Carpal Tunnel Syndrome: Carpal Tunnel Syndrome (CTS) is a condition that occurs when the median nerve, which runs through the wrist, becomes compressed. It can cause pain, tingling, and numbness in the hand and fingers.

Symptoms of Wrist Injuries

  • Pain: Pain is the most common symptom of a wrist injury. The location and severity of the pain will depend on the type of injury.
  • Swelling: Swelling is another common symptom of a wrist injury. It can occur at the site of the injury and may be accompanied by redness and warmth.
  • Bruising: Bruising can occur as a result of a wrist injury, especially if there is a fracture or dislocation.
  • Deformity: Some wrist injuries, such as fractures or dislocations, can cause a deformity in the joint.
  • Loss of function: A wrist injury can also cause loss of function in the joint, making it difficult to move the hand and fingers.

Causes of Wrist Injuries

  • Trauma: Trauma is the most common cause of wrist injuries. Falls, car accidents, and sports injuries are common causes of traumatic wrist injuries.
  • Overuse: Repetitive motions or overuse of the wrist can lead to injuries such as tendinitis or CTS.
  • Arthritis: Arthritis is a degenerative condition that can affect the wrist joint, leading to pain and loss of function.
  • Bone disorders: Certain bone disorders, such as osteoporosis, can make the bones more susceptible to fractures.

Wrist injuries can range from mild sprains to severe fractures and dislocations. Prompt diagnosis and treatment are essential for a successful recovery. In the next chapter, we will discuss the diagnostic and evaluation process of wrist injuries.

Diagnosis and Evaluation of Wrist Injuries

An accurate diagnosis is crucial in order to provide appropriate treatment for a wrist injury. The diagnostic process typically begins with a thorough physical examination and a review of the patient’s medical history.

Physical Examination

During the physical examination, the healthcare provider will:

  • Inspect the wrist for signs of injury, such as swelling, bruising, or deformity.
  • Palpate the wrist to feel for tenderness, crepitus (grinding sensation), or instability.
  • Test the range of motion and strength of the wrist and hand.
  • Test for sensation in the hand and fingers.

Imaging Studies

Imaging studies are often used to confirm the diagnosis and determine the extent of the injury. The types of imaging studies that may be used include:

  • X-ray: X-rays are often the first imaging study performed in suspected wrist injuries. They can show the presence of fractures or dislocations.
  • Computed Tomography (CT): CT scans can provide detailed images of the bones and can be useful for identifying fractures that are not visible on x-ray.
  • Magnetic Resonance Imaging (MRI): MRI scans can provide detailed images of the soft tissues, such as ligaments and tendons. They can be useful in evaluating injuries to these structures.

Specialized Tests

Specialized tests may be used to further evaluate the wrist injury. These include:

  • Arthrography: Arthrography is a special type of x-ray that involves injecting a contrast dye into the joint. This can help to identify injuries to the ligaments or cartilage.
  • Nerve Conduction Studies: Nerve conduction studies are used to evaluate the function of the median nerve in patients with suspected CTS.

Differential Diagnosis

In some cases, the diagnosis of a wrist injury may be difficult to establish. The differential diagnosis for wrist pain includes:

  • Arthritis: Arthritis can cause pain and stiffness in the wrist.
  • Tendinitis: Tendinitis can cause pain and weakness in the wrist and hand.
  • Carpal Tunnel Syndrome: CTS can cause pain, tingling, and numbness in the hand and fingers.
  • Referred pain: Pain in the wrist can also be referred from other structures, such as the neck or shoulder.

An accurate diagnosis is essential for appropriate treatment of a wrist injury. In the next chapter, we will discuss the conservative and non-surgical treatment options available for wrist injuries.

Conservative Treatment Options for Wrist Injuries

The goal of treatment for a wrist injury is to reduce pain and inflammation, promote healing, and restore function. In many cases, conservative treatment options can effectively achieve these goals.

Rest and Immobilization

Rest and immobilization are often the first line of treatment for a wrist injury. This can help to reduce pain and inflammation and promote healing. The type of immobilization used will depend on the specific injury:

  • Casting: A cast may be used to immobilize a broken bone and keep it in proper alignment.
  • Splinting: A splint may be used to immobilize the wrist in cases of sprains or ligamentous injuries.
  • Bracing: A brace may be used to immobilize the wrist and provide support in cases of chronic instability or arthritis.

Medications

Medications can be used to reduce pain and inflammation. The types of medications that may be prescribed include:

  • Nonsteroidal Anti-inflammatory Drugs (NSAIDs): NSAIDs, such as ibuprofen and naproxen, can help to reduce pain and inflammation.
  • Corticosteroids: Corticosteroids, such as prednisone, can be used to reduce inflammation. They can be taken orally or injected into the joint.

Physical Therapy

Physical therapy can be an effective treatment for a wrist injury. A physical therapist can design an individualized exercise program that will help to improve range of motion, strength, and function. The specific exercises will depend on the nature of the injury.

Occupational Therapy

Occupational therapy can also be beneficial for a wrist injury. An occupational therapist can teach the patient how to perform daily activities in a way that will not aggravate the injury. They can also teach the patient how to use assistive devices, such as splints, to help with gripping and grasping.

Other Treatment Options

Other treatment options that may be used for a wrist injury include:

  • Ultrasound: Ultrasound therapy can be used to reduce pain and inflammation.
  • Heat and cold therapy: Applying heat or cold to the wrist can help to reduce pain and inflammation.

It’s important to note that the treatment plan will depend on the specific type, severity and cause of the injury. Conservative treatment options are often effective in treating wrist injuries, but in some cases surgery may be necessary. In the next chapter, we will discuss surgical intervention for severe wrist injuries.

Surgical Intervention for Severe Wrist Injuries

In some cases, conservative treatment options are not sufficient to adequately treat a wrist injury. In these cases, surgical intervention may be necessary. The type of surgery will depend on the specific injury and the goals of treatment.

Fractures

Fractures that do not heal properly or that cause significant deformity may require surgical intervention. The type of surgery will depend on the location and type of fracture. Surgery may be used to:

  • Realign the bones: Surgery may be performed to realign the bones and hold them in place with plates, screws, or pins.
  • Remove loose fragments of bone: Loose fragments of bone can cause pain and limit the function of the wrist. Surgery may be performed to remove these fragments.
  • Fuse bones: In some cases, the bones may be fused together to promote healing and improve stability.

Dislocations

Dislocations that are not reducible or that cause significant instability may require surgical intervention. Surgery may be used to:

  • Repair or reconstruct ligaments: Ligaments that have been torn or stretched as a result of a dislocation may need to be repaired or reconstructed.
  • Realign bones: Surgery may be performed to realign the bones and hold them in place with plates, screws, or pins.

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome is a condition that occurs when the median nerve becomes compressed as it passes through the wrist. Surgery may be necessary for patients who do not respond to conservative treatment options. Surgery for CTS typically involves the following procedure :

  • Release of the transverse carpal ligament: Surgery is performed to release the transverse carpal ligament, which compresses the median nerve, thus relieving the pressure on the nerve.

Risks and Complications

As with any surgery, there are risks and potential complications associated with surgical intervention for wrist injuries. These include:

  • Infection: An infection can occur at the surgical site.
  • Nerve or blood vessel injury: There is a risk of injury to the nerves or blood vessels during surgery.
  • Nonunion: In some cases, the bones may not heal properly after surgery.
  • Stiffness: Surgery may result in stiffness in the joint.

In consultation with a surgeon, patients can weigh the risks and benefits of surgery and make an informed decision. It is important to note that in most cases, surgical intervention is only recommended as a last resort after non-surgical treatments have failed. In the next chapter, we will discuss the rehabilitation and recovery process for wrist injuries.

Rehabilitation and Recovery from Wrist Injuries

Rehabilitation and recovery are an important part of treatment for a wrist injury. The goal of rehabilitation is to restore function and range of motion to the joint, while minimizing pain and inflammation.

Physical Therapy

Physical therapy is an important component of rehabilitation for a wrist injury. A physical therapist can design an individualized exercise program that will help to improve range of motion, strength, and function. Exercises may include:

  • Range of motion exercises: Range of motion exercises can help to improve the flexibility and mobility of the joint.
  • Strength exercises: Strength exercises can help to improve the strength and stability of the joint.
  • Functional exercises: Functional exercises can help to improve the ability to perform daily activities, such as gripping and grasping.

Occupational Therapy

Occupational therapy can also be beneficial for a wrist injury. An occupational therapist can teach the patient how to perform daily activities in a way that will not aggravate the injury. They can also teach the patient how to use assistive devices, such as splints, to help with gripping and grasping.

Recovery Time

Recovery time will vary depending on the specific injury, the type of treatment, and the individual’s response to treatment. Fractures and dislocations may require a longer recovery time, while sprains and tendinitis may have a shorter recovery time.

Return to Activity

The patient should not return to activities that involve heavy use of the wrist until they have fully recovered. It’s important to follow the instructions of the healthcare provider and physical therapist and not to return to activity too soon, as this can delay recovery and lead to further injury.

Preventing Recurrence

To prevent recurrence of injury, it is important to address any underlying issues that may have contributed to the original injury, such as poor posture, ergonomic issues, or muscle imbalances. A physical therapist or occupational therapist can help to identify and address these issues.

In conclusion, rehabilitation and recovery are an essential part of the treatment process for wrist injuries. By following a comprehensive treatment plan, patients can regain function and reduce the risk of recurrence. It is important for patients to work closely with their healthcare providers and physical therapists to ensure a successful recovery.
