A sprained thumb is a painful condition caused due to an injury on the ligament of a thumb. A ligament is a soft tissue, which connects bones to each other at a joint. The ligament might get partially or fully torn due to extreme backward bending of thumb causing the ligament connecting the thumb and index finger to suffer injury.

The problem is quite common among basketball, rugby and football players. For this reason, it is known as a sports injury. Skiing may also cause extreme pressure to the thumb, causing a ligament tear. Injury due to skiing is called skier s thumb.

The injury causes pain, bruising and tenderness. It can cause swelling on just the thumb or sometimes on the entire hand. In severe cases, weakness and instability in the region can be seen. A sprained thumb weakens the ability to pinch and grasp things. The patient will have trouble holding a glass, turning a knob or writing. An untreated injury may lead to joint stiffness, muscle weakness, scar tissue formation, instability of the thumb or even arthritis. It is strongly advised to visit a professional therapist for an early diagnosis and treatment.

Usually, an X-ray leads to an apt diagnosis of the injury. The doctor also ascertains damage to the bone and ligament and develops a treatment plan. Some ligament tears can be treated using a splint or cast. A chronic ligament tear might not heal and would require surgical intervention.

A partial or mild ligament tear can be managed through useful home remedies like putting an ice pack, bandage or splint. It is also advised to keep the thumb elevated and restrict its movement. A heat pack is beneficial as it can ease pain and relax the muscles. However, heat pack must be avoided during the first 48 hours of injury as it can lead to bleeding.

If there is a chronic injury and the ligament is completely torn, a surgery is needed. A surgery helps join a new ligament to the bone in case the torn ligament fails to heal. It also helps reconnect the injured ligament to the bone. Sometimes, there might be bone damage as bone fragments might get pulled away with the ligament. In such cases, bone fragments need to be put back in their position through surgery. After the surgery, a cast or splint is put till it heals completely.

An early visit to a physiotherapist has potential advantages. A therapist can fasten the healing process, help relieve pain and improve a person s ability to resume daily tasks. Massages and strengthening exercises are initiated to avoid re-injury and instill strength in the injured region. Physiotherapy also helps immensely after surgery through planned mobility exercises that regain movement and strength.  

Sprained Thumb- Causes and Treatment

From marathon runners to footballers, amongst athletes, 'pulling a hamstring' is the most common type of injury. The hamstring is a group of four muscles at the back of your thigh. When one of these muscles gets overloaded or begins to tear, it is known as a hamstring injury. While a hamstring injury is painful, it does not indicate the end of an athlete's career.

Minor hamstring injuries may heal by themselves. In cases where one of the muscles is torn, surgery is required to repair and reattach the muscles. Recovery time depends on the severity of the injury. Stretching and exercising the muscles of the leg are the most important parts of rehabilitation. The healing of a hamstring injury can be divided into four stages.

1. Acute phase: The first five days after a hamstring injury is known as the acute phase of rehabilitation. The aim of treatment at this phase is to reduce inflammation and keep the other muscles from atrophy. For minor hamstring injuries resting the leg, using ice packs and keeping the leg elevated can accelerate the healing process. Once the pain and swelling has decreased, patients can use a cane or crutch to exercise the leg.

2. Subacute phase: From the fifth day to the 3rd week after the injury, the focus of the treatment shifts from minimizing swelling to strengthening the leg and increasing the range of possible motions. At this time, an athlete can resume cardiovascular training. Swimming and other forms of aquatic training are said to be especially beneficial to the treatment of hamstring injuries.

3. Remodeling phase: The remodeling phase continues upto 6 weeks after the injury. Strengthening the leg is the focus of this stage of treatment. Using ankle weights can be beneficial towards strengthening the leg muscles. It is important to be careful about the weight being used and to gradually increase this weight to avoid an added injury.

4. Functional stage: This stage can last upto 6 months until the athlete can regain full function of his or her leg. As the athlete's gait gets back to normal, they may start jogging and short sprints. Gradually, more sport specific exercises may be added to the workout.

There is no fixed time when an athlete can return to active sports after a hamstring injury. While players with minor injuries may return to the field after 3 weeks, athletes with muscles tears may take upto 6 months to recover completely. Hamstring injuries tend to reoccur and hence before they can get back to active sports, an athlete must pass an isometric strength test and flexibility test. This ensures that there are no subtle after effects of the injury that can increase the risk of a repeat injury.

Hamstring Injury Recovery and Return to Sports

Avascular Necrosis, also termed as Ischemic Bone Necrosis or Osteonecrosis is a medical condition characterized by the bone death on being deprived of blood. The condition is known to occur in the shoulder, ankles, and knees. However, the part of the body most affected by Avascular Necrosis is the hip. In this article, we will describe the conditions that contribute towards Avascular Necrosis of the hip along with the associated symptoms.

Factors that lead to Avascular Necrosis of the hip
The supply of blood to the bones may be interrupted by a myriad of factors some of which include

1. Certain medical conditions and health disorders such as

Gaucher's disease: A genetic disorder resulting from glucocerebrosidase enzyme deficiency. As a result, glucocerebroside gets deposited in the cells of the macrophage-monocyte system.
Sickle cell anemia: A genetic disorder which results in the RBC's appearing like a sickle cell instead of being round shaped.
Both of these conditions bring about a significant reduction in the supply of blood to the bones resulting in Avascular Necrosis.

Certain inflammatory conditions that may damage the arteries and trigger Avascular Necrosis of the hip include autoimmune diseases, pancreatitis or HIV infection.

2. Extensive and prolonged use of corticosteroids: Often used as non-inflammatory drugs, corticosteroids can play a contributing role, resulting in Avascular Necrosis (non-traumatic). The fatty substances are usually broken down by the body. However, the use of corticosteroids may affect this breakdown as a result of which the fatty substances start piling up in the blood vessels, constricting their size. The constricted blood vessels, in turn, reduces the supply of blood to the bones to a great extent.

3. An injury or a fracture affecting the femur: A hip fracture or a dislocation that affects the upper half of the thigh bone or the femur acts as a potential threat, triggering a traumatic Avascular Necrosis (AVN) of the hip.

In some case, radiation therapy or chemotherapy for cancer can go a long way in interfering with the ability of the bone (weakens the bone) to receive blood, causing bone death.

People who are into heavy drinking stand a greater risk of suffering from AVN. An increased consumption of alcohol causing constriction and narrowing of the blood vessels interfering with the flow of blood to the bones.

Symptoms characteristic of AVN of the hip

Unfortunately, the initial stages of AVN are asymptomatic. However, as the condition progresses into later stages, a person may experience pain and discomfort, particularly while exerting pressure on the bone affected by the condition.
As the bone and the adjacent joints deteriorate and collapse further, a person may experience great difficulty in using the joint altogether.
In some cases, the condition may progress and affect both the hips (Avascular Necrosis Bilateral).

Causes and Symptoms of Avascular Necrosis of the Hip

If you are an avid runner, then you might also be well aware of the type of running injuries one is prone to. It might be foolish to say that running injuries can be prevented. It is because these injuries do happen quite often. Though these cannot be prevented, these can definitely be treated. Furthermore, precautions from your side can always be taken to make sure that these injuries do not cause a major impact on your health and can be cured without much of a hassle. Here are some important points that you need to remember to avoid running injuries or to lessen their adverse impact on your body.


Flexible Body: Flexibility is an important part of a runner s body. You not only need to have the stamina to run, but also must possess flexible features to get you out swiftly from any serious damage. Flexibility is attained when you do regular exercises and stretching in particular. It makes your muscles resilient towards many injuries and provides your body a better shape and long lasting stamina as well.
Strengthen Your Body: Body strength is required if you want to avoid any sports injuries. Special strength training sessions are organised with the coaches of sportspersons. These sessions help in building up muscle strength. This would, in turn, lessen muscle fatigue and make you able enough to perform better.
Balanced Diet: It does not matter whether you are an athletic or not, a balanced diet is needed for everyone. Balanced diet does not mean picking and choosing of food. It means a proper diet chart, mapping everything that your body needs to stay fit. Furthermore, it should contain ample amount of water to keep you hydrated.
Take Rest When Required: It is often said by the elders that too much of work would ruin your health and body. Thus, even for the athletes, it is important to take rest in between periods of heavy training sessions. This would give you a chance to relax your body and relieve you of all the stress. Furthermore, if you are injured or hurt, it would give you ample time to recover from your injuries.
Wear Proper Shoes: As a runner, you need to take care of all parts of your body. This would also include your legs. To prevent any sprains or muscle injury in the leg and to practice for long hours, proper running shoes are needed.  


How To Avoid Running Injuries?

The core muscles, mainly concentrated around the abdomen, hips, lower back, trunk, and glutes, are indeed a powerhouse that gets you going. The stronger the core muscles, the fitter you stay. Without a proper core strength, a lot of the day to day activities including lifting or bending gets affected. Certain health conditions can weaken the core muscles. But how to know if the core muscles are weak? There are many signs and symptoms associated with weak core muscles. 

Mentioned below are some important signs that may be an indication of weak core muscles.

For your posture to be correct, the spine and pelvis need to be stable: The muscles of the lower back and the abdomen does exactly that, ensuring a steady and correct posture. However, when the core muscles weaken, they are unable to provide stability to the spine and the pelvis resulting in a poor posture. Left unattended, poor posture, in turn, can trigger a myriad of complications and discomfort.
The body loses its balance: As already mentioned, the core muscles go a long way in stabilizing the body and helping you to maintain the body balance. You can perform a small test to know if your balance is affected. Close your eyes and stand on one foot. Repeat the procedure with the other foot as well. If you have a developed core, you will be able to hold the position for at least 10 seconds, if not more (both the legs).
A pain concentrated to the lower back: Do not ignore a lower back pain. It could be an indication of your core muscles not being strong enough, especially the ones adjacent to the spine. The weak muscles fail to provide the necessary support to the discs and the vertebrae resulting in pain (mild to severe depending on the severity of the condition) and discomfort. Timely medical intervention may help improve the condition.
Weakness throughout the body: The strong core muscles are an indication of a healthy and fit body. When the muscles start to lose its strength, the entire body gets affected. A person finds it difficult to even lift things. Doing even a small and regular work leaves a person weak and tired.
You can also perform the Hollowing Test to check your core strength: Sit in a comfortable position. Starting breathing in and out. As you breathe out or exhale, try to pull your stomach inwards towards the spine for at least 10 seconds. Unable to pass this test (can't hold the position for 10 seconds) indicates weak core muscles.
You can also try the plank test: Get yourself in a push-up position with the entire body resting on your elbows, arms, and toes. The hip should be level and steady. Failing to stay in this position for 50 seconds is indicative of weak core muscles

Core Muscles - How To Know If They Are Strong Or Weak?

A small piece of bone is known as a fragment and it is very common that an avulsion fracture also tends to damage the protrusions of bone to which the tendons attach. This basically means that the tendon or ligament will come away from the bone and it will take a small piece of bone with it. It is sometimes very hard to find out what type of injury you have and this is why knowing the causes and symptoms of an avulsion fracture are very helpful in determining exactly how severe the injury is. 
Here are the causes of an avulsion fracture.
Causes:
Explosive Landing: Athletes who tend to jump or land with great impact tend to get these most commonly. Therefore, it is crucial for your health that if you participate in such sports, you do follow the correct method of jumping.
Explosive Extension: Similar to how an athlete landing ferociously can get an avulsion fracture, someone who is extending the legs very violently and explosively during an exercise can also get an avulsion fracture. This is because the bone getting extended could very well damage the protrusions to which the tendons are attached. 
Symptoms:
These are the two main causes of an avulsion fracture. There are not many symptoms of an avulsion fracture. This is because an avulsion fracture can only be determined by an MRI or by an X-ray scan. Therefore it is nearly impossible to diagnose that you have an avulsion fracture without looking at the results of the tests performed on the part of your body. However, the way you got the fracture and especially the details of it are very good indications of whether you have an avulsion fracture or not.
