What Is Jammed Finger?

Overview

A jammed finger is a common injury that occurs when the finger is forcefully bent or twisted, causing the joint to become temporarily immobilized. The injury can affect any finger joint, but it commonly occurs in the middle joint, known as the proximal interphalangeal joint (PIP). While jammed fingers are often minor and heal on their own with time, more severe cases may require medical attention, including splinting, pain management, and rehabilitation exercises to restore full functionality. It is important to seek medical advice if there is severe pain, significant swelling, or if the finger appears deformed or unable to move normally.

Grades of jammed finger

Jammed fingers can be categorized into different grades based on the severity of the injury. The grading system typically ranges from mild to severe and helps in determining the appropriate treatment approach. Here are the common grades of jammed finger:

Grade 1: Mild jammed finger

In this case, there are minor tears in your ligament. However, your bones are unlikely to shift out of position, and the joint is secure. You may notice:

• Minimal swelling and pain
• No joint instability or deformity
• A full range of motion is possible

Grade 2: Moderate jammed finger

If your ligament has partly ripped, the injury is classified as Grade-2 There is a slight potential that your bones could move out of position. It presents as:

• Moderate swelling and pain
• Mild joint instability or minor deformity
• Limited range of motion or difficulty in flexing and extending the finger

Grade 3: Severe jammed finger

At this Grade, it means your ligament has been totally ripped. Your joint has significant instability and your bones could possibly drift out of alignment. The possible symptoms may include:

• Severe swelling, pain, and tenderness
• Significant joint instability or visible deformity
• Limited or no ability to move the finger

Causes of jammed finger

It can be due to an injury or an accident such as falling. It typically happens during activities that involve catching, throwing, or gripping objects. When a finger is jammed, the ligaments and soft tissues surrounding the joint are stretched or partially torn, resulting in pain, swelling, and limited mobility. It is also called a sprained finger or an injured finger. Here are some common causes of jammed fingers:

• Sports Injuries

Injured fingers frequently occur during sports activities such as basketball, football, volleyball, or handball, where the finger may get forcefully struck by a ball, collide with another player, or get caught in equipment.

• Accidental Impact

 Every day accidents, such as slamming a finger in a door, hitting it against a hard surface, or dropping a heavy object on the finger, can lead to a jammed finger.¹

• Falls

Falling and landing on an outstretched hand can cause the fingers to bend abruptly, leading to a jammed finger.

• Occupational Hazards

Certain professions or activities that involve repetitive finger movements or handling heavy objects, such as construction work, carpentry, or manual labour, increase the risk of jammed fingers.

• Physical Altercations

During altercations or fights, a finger may get forcefully twisted or bent, resulting in a jammed finger.

It's important to note that while jammed fingers are typically non-serious injuries, they can occasionally lead to more severe conditions, such as fractures, dislocations, or ligament damage.

Signs and symptoms of jammed finger

Here are the common indications of a jammed finger:

• Pain and Tenderness

One of the primary symptoms of a jammed finger is pain. The affected finger joint becomes tender and sensitive to touch. The intensity of the pain can range from mild to severe, depending on the severity of the injury.

• Swelling

Jammed fingers often exhibit swelling around the injured joint. The swelling occurs as a result of inflammation in the soft tissues surrounding the joint. The degree of swelling can vary, with more severe cases showing noticeable enlargement of the affected area.

• Limited Range of Motion

Another common symptom is a reduced range of motion in the jammed finger joint. The injured finger may have difficulty flexing or extending fully. Attempting to move the finger may cause discomfort or pain.

• Stiffness

Stiffness is a characteristic feature of a jammed finger. The injured joint may feel rigid or resistant to movement, making it challenging to perform normal finger movements or activities that require gripping or bending the finger.

• Bruising

In some cases, bruising or discolouration may develop around the jammed finger joint. This occurs due to bleeding from damaged blood vessels in the injured soft tissue. The bruise may appear as a bluish or purplish mark.²

• Sensation Changes: 

Numbness or tingling sensations may be experienced in the affected finger due to nerve irritation or compression caused by the injury.

Management and treatment for jammed finger

• Rest: Avoid activities that put stress on the jammed finger, allowing it to rest and heal.
• Immobilization: Splinting or buddy-taping the injured finger to an adjacent finger can provide stability and support during the healing process
• Ice: Applying ice packs or cold compresses to the jammed finger helps reduce pain, swelling, and inflammation. It should be done for about 15-20 minutes at a time, several times a day
• Elevation: Keeping the injured finger elevated above heart level can assist in reducing swelling.
• Pain Relief: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or acetaminophen, can be taken to alleviate pain and discomfort³
• Gentle Exercises: Once the acute phase has passed, performing gentle range-of-motion exercises and finger stretches can help restore flexibility and prevent stiffness
• Gradual Return to Activities: Slowly reintroduce activities involving the jammed finger, gradually increasing intensity and stress to avoid re-injury
• Medical Evaluation: Seek medical attention if there is severe pain, significant swelling, deformity, or if the finger is unable to move normally. A healthcare professional can assess the injury, provide appropriate treatment, and rule out any fractures or ligament damage

The management and treatment may vary depending on the severity of the jammed finger. It is recommended to consult a healthcare professional for an accurate diagnosis and personalized treatment plan.

Diagnosis

For diagnosis your healthcare provider may diagnose according to the grades specified above.

For grade 1: 

Self-care measures such as rest, ice, compression, and elevation (RICE) are usually sufficient for diagnosis and recovery.

For grade 2: 

Medical evaluation may be necessary to assess the extent of the injury and provide appropriate treatment.

For grade 3: 

Medical attention is crucial, as this grade may indicate a more serious injury, such as a fracture or dislocation. X-rays or other imaging tests such as an MRI may be needed for accurate diagnosis, and treatment may involve reduction (repositioning of bones), splinting, immobilization, pain management, and possibly surgical intervention.

Risk factors

• Lack of proper protective equipment, such as gloves or finger splints, during activities with a high risk of finger injuries
• Poor technique or form during sports or physical activities, increasing the likelihood of finger trauma
• Engaging in activities with potential hazards, such as working with heavy machinery or objects that can crush or trap fingers
• Insufficient warm-up or stretching before physical activities, which can reduce joint flexibility and increase the risk of injury
• Previous history of finger injuries, as the affected joint may be more susceptible to future jammed finger incidents
• Age, as younger individuals who are more active and participate in sports may be at a higher risk due to increased exposure to potential finger injuries

Complications

• Chronic Pain

In some cases, a jammed finger can lead to persistent or chronic pain, even after the initial injury has healed.

• Stiffness and Reduced Range of Motion 

Failure to properly rehabilitate the jammed finger can result in long-term stiffness and limited mobility in the affected joint.

• Joint Instability

Severely jammed fingers or untreated injuries can lead to joint instability, making the finger more prone to recurrent dislocations.

• Development of Arthritis

Repeated or severe jammed finger injuries can increase the risk of developing arthritis in the affected joint over time, leading to chronic pain, inflammation, and reduced joint function.

• Functional Impairment

Depending on the severity and location of the injury, a jammed finger can affect daily activities, gripping objects, typing, or performing fine motor tasks.

• Nerve Damage

Severely jammed fingers or associated fractures can potentially damage nerves in the finger, resulting in numbness, tingling, or altered sensation.
