When a joint is forced beyond its normal range of motion in the opposite direction of its normal flexion, joint hyperextension injury will happen. This type of injury can damage the joint, ligaments, tendons, and other soft tissues surrounding the joint.
Joint hyperextension injuries commonly occur to individuals participating in sports that involve jumping, landing, or sudden changes in direction, such as basketball, football, and soccer. These injuries can also occur in daily activities such as missing a step on the stairs.
The common joint hyperextension injuries are:
-
Hyperextension of the ankle joint
This injury occurs when the ankle joint is extended beyond its normal range of motion. It is commonly seen in sports that involve jumping or sudden changes in direction, such as basketball or soccer.
-
Hyperextension of the knee joint
This injury occurs when the knee is bent backwards beyond its normal range of motion. Common injuries include anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and meniscal tears.
-
Hyperextension of the elbow joint
This injury occurs when the elbow joint is extended beyond the normal range of motion due to sudden forceful trauma or from repetitive stress of the joint.
-
Hyperextension of the shoulder joint
This injury occurs when the shoulder joint is hyperextended. It is commonly seen in sports that involve overhead movements, such as volleyball or swimming.
-
Hyperextension of the fingers
This injury occurs when the fingers are bent backwards beyond the normal range of motion. Common finger hyperextension injuries include sprains and dislocations.
Joint hyperextension injuries risk factors
- With aging, our joints may become less flexible and more susceptible to hyperextension injuries.
- Poor or improper technique during participation in high-impact activities such as running, gymnastics, racquet sports and martial arts may cause excessive strain on the joints and increase the risk of hyperextension injuries.
- Weak muscles around the joints may increase the risk of hyperextension injuries due to inadequate support and stability.
- Previous injury may weaken the ligaments and tissues around the joint, making them more susceptible to hyperextension injuries.
- Joint laxity or having unstable joints may be cause an individual to be more susceptible to joint hyperextension injuries.
Joint hyperextension injuries symptoms
Common symptoms include the following:
- Pain
- Joint swelling
- Bruising
- Stiffness
- Muscle spasm
- Joint instability
However, symptoms may vary depending on the severity of the injury.
Joint hyperextension injuries diagnosis
Your doctor would first question your general health and symptoms before conducting a thorough physical examination. Diagnosis is made based on your reported symptoms, physical examination, and investigations.
Imaging tests may be used to evaluate the severity of the injury and help identify any fractures, dislocations, or other structural damage that may have occurred due to the injury. These tests include X-rays, computed tomography (CT) scans, or magnetic resonance imaging (MRI).
Joint hyperextension injuries treatment options
Treatment for a hyperextended joint injury depends on the severity of the injury, the joint involved, and other factors such as age, overall health, and activity level.
In general, treatment for a hyperextended joint injury may include the following:
- PRICE - Protection, Rest, Ice, Compression, Elevation
PRICE is a common approach for the first two or three days.
- Protection: The use of protective support such as an elastic bandage, splint, or cast, depending on the extent of the injury.
- Rest: Limit weight bearing and avoid activities that may aggravate the injury.
- Ice: Apply ice packs to the affected area for at least 15 to 20 minutes, several times a day, until swelling improves.
- Compression: To reduce swelling and support the joint by wrapping the affected joint with an elastic bandage.
- Elevation: Keep the affected joint above the level of the heart to reduce swelling.
- Medication: Pain and swelling can be managed with oral or topical nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen.
- Physiotherapy: Range of motion exercises only after the acute pain and swelling have subsided.
However, if the injured joint remains swollen or painful for several days despite the measures above, you need to be evaluated by an orthopaedic specialist to ensure there is no fracture and to determine the suitable treatment option.
Joint hyperextension injuries prevention
- Engage in adequate stretching, warming up, and use proper techniques when participating in high-impact activities.
- Let your joints have adequate rest and recovery time between workouts and activities because overuse of the joints can increase the risk of hyperextension injuries.
- Avoid standing on countertops, chairs, or tables when reaching for things. Always use the right tools or equipment.
- Wear supportive shoes to provide additional support for the joints and reduce the risk of hyperextension injuries.
