muscle problems
locomotor function
* weakness eg. trendelenburg
* spasticity eg. cerebral palsy
* tightness e.g piriformis syndrome- compresses sciatic nerve
* combinations e.g pelvic crossed syndrome
septic arthiritis
definition, risk factors, symptoms
- an infection in the joint (synovial) fluid and joint tissues
- The infection usually reaches the joints through the bloodstream. In some cases, joints may become infected due to an injection, surgery, or injury.
Risk factors
- A systemic blood-borne infection
- IV drug use
- Osteoarthritis
- Past history of septic arthritis
- Rheumatoid arthritis
Other factors that may increase the risk for septic arthritis include:
* Alcoholism
* Diabetes
* HIV
* Lung or liver disorders
* Old age
* Suppressed immune system
Symptoms
* Fever
* Joint pain
Joint swelling
osteomyelitis
causes, pop, treatment
- Osteomyelitis is inflammation or swelling that occurs in the bone usually a result of infection
Causes
* It can result from an infection somewhere else in the body that has spread to the bone, or it can start in the bone — often as a result of an injury.
Population
* Osteomyelitis is more common in younger children (five and under) but can happen at any age.
* Boys are usually more affected than girls.
Treatment
* Antibiotics are often prescribed to treat osteomyelitis. Surgery may also be recommended in certain cases.
meralgia paraesthestica
symptoms, definition, population
Meralgia Paraesthestica -
- tingling, numbness, and burning pain in the outer side of the thigh. The disorder occurs when the lateral femoral cutaneous nerve is compressed or squeezed as it exits the pelvis.
- The condition results from compression (pressure on or squeezing) of your lateral femoral cutaneous nerve (LFCN). This large nerve supplies sensation to the front and side of your thigh.
Symptoms
Symptoms of meralgia paresthetica only occur on one side of your body in the front of your upper thigh. They include:
* Pain, which may extend down to the outer side of your knee.
* Burning, aching, tingling or numbness in your thigh.
* Increased pain sensitivity (for example, gently touching your thigh may cause pain).
* Worse pain after walking or standing for long periods.
Meralgia paresthetica doesn’t directly cause issues with your muscles or movement.
Population
* injury or surgery in your hip area.
* Medical conditions like obesity, pregnancy and diabetes.
* Wearing clothing that’s too tight or belts around your waist.
* A tumor near your LFCN.
trochanteric bursitis
- pain and inflammation of tissues that are situated around the outer part of the hip or upper thigh.
- The greater trochanter is a large, bony point that you can feel on the outside of the upper thigh.
- It serves as a useful attachment point for muscles that help stabilise your pelvis.
- The bursa is a type of thick tissue that helps to reduce friction between the bone (greater trochanter) and the tendons (gluteal tendon).
- In some cases, irritation of these bursae tissues can lead to pain and inflammation. This is how the term “trochanteric bursitis” originated
Symptoms
- Pain that is located around the lateral of the upper thigh/hip and may radiate further down the outer thigh.
- Commonly there is tenderness over the lateral hip.
- struggle to sleep on the affected side.
- pain is worse with tasks that involve standing on one leg such as walking, running, dressing and climbing the stairs.
- The pain can be worse for the first few steps after sitting when sitting crossed legged, sitting in a low chair or lying on the non-painful side and the affected leg drops down. This is because all these positions increase the compression of the tendon and bursa
Population
- Women are more prone to GTPS because of pelvic biomechanics, different activity levels in the population and hormonal effects.
- Females have a smaller insertion of the Glute med tendon, resulting in: smaller area across which tensile load could be dissipated
- Female: male 4:1 40-60 years old.
- It can affect people who are both active and sedentary.
You are more likely to suffer from it if you already have low back pain, hip osteoarthritis or you are overweight
Illiotibial band syndrome
- Iliotibial band syndrome (ITBS) is a common knee injury that usually presents with pain and/or tenderness on palpation of the lateral aspect of the knee, superior to the joint line and inferior to the lateral femoral epicondyle.
- The iliotibial tract is a thick band of fascia that runs on the lateral side of the thigh from the iliac crest and inserts at the knee. It is composed of dense fibrous connective tissue that appears from the m. tensor fasciae latae and m. gluteus maximus. It descends along the lateral aspect of the thigh, between the layers of the superficial fascia, and inserts onto the lateral tibial plateau at Gerdy’s tubercle
- non-traumatic overuse injury
- often concomitant with underlying weakness of hip abductor muscles
- this condition is likely to be caused by compression of the innervated local adipose tissue
- ‘impingement zone’ occurring at, or slightly below, 30° of knee flexion during foot strike and the early stance phase of running. During this impingement period in the running cycle, eccentric contraction of the tensor fascia latae muscle and of the gluteus maximus causes the leg to decelerate, generating tension (compression) in the iliotibial band.
Symptoms
- sharp pain on the outer aspect of the knee, particularly when the heel strikes the floor, that can radiate into the outer thigh or calf
- worse when running or coming down stairs
- audible snapping sensation the knee bends due to the band flicks over the bony tubercle.
- There may also be some swelling on the outer side of the knee.
Population
- Runners
sports involving repeated knee flexion and extension, such as cyclists and runners
Avascular necrosis
- a painful bone condition that gets worse over time and can affect your mobility. It occurs when something cuts off blood flow to one of your bones.
- when something blocks the flow of blood to your bone tissue
- Without blood flow, your skeletal system can’t make new bone tissue fast enough. The dying bone begins to crumble and eventually collapses.
Aetiology
- Traumatic avascular necrosis: This can happen after you break a bone or dislocate a joint.
- Nontraumatic avascular necrosis: This happens if you have an illness or medical condition that keeps blood from flowing to your bone tissue. Nontraumatic avascular necrosis often affects the same bones on both sides of the body. For example, if you have avascular necrosis in your right shoulder, you’re likely to have it in your left shoulder.
- interruption of blood supply to the bone. Femoral head ischaemia causes bone marrow and osteocytic death, leading to collapse of the necrotic segment of the head of femur.
Stages
1. Initial/necrosis:blood supply gets disrupted, and necrosis begins
2. Fragmentation: the body resorbs the necrotic bone and replaces it with woven bone that is weak and vulnerable to breaking and collapse
3. Reossification: stronger bone develops
4. Healed/Remodeling: bone regrowth is complete, and final shape present (depending on damage may be normal or abnormal)
Symptoms
- Minimal early joint pain
- Increased joint pain as bone and joint begin to collapse
- Limited range of motion due to pain
- Pain in the groin
- Painful rom especially in internal rotation
Risk factors
- Genetic predilection
- Corticosteroid intake
- Alcohol
- Smoking
- Chronic diseases- sickle cell disease, human immunodeficiency, autoimmune disorders
Diagnosis
- Radiographs in mid/late disease
Mri in early
