Question

1. Write one to two paragraphs about the most common joint injuries.

2. Write a one-page report about crystal-induced arthropathy

Answer 1

The most common joint injuries are dislocations naf subluxation

Dislocation: a joint is dislocated when the articular surface are completely displaced one from the other

Subluxation: a joint is subluxated when it's articular surfaces are only party displaced

CLASSIFICATION

.Traumatic dislocation

. Pathological dislocation

DIAGNOSIS

Clinical examination

Clinical features-

. Pain

. Deformity

. Shortening of limb

. Telescopy

RADIOLOGICAL EXAMINATION

. Xray

. Ct scan

COMPLICATIONS

. Recurrence, myositis ossificans, instability,stiffness, osteoarthritis, avascular necrosis

TREATMENT

. Conservative methods

.Operative methods

CRYSTAL INDUCED ARTHROPATHY

. Disturbed purine metabolism leading to excessive accumulation of uric acid in the blood, can be an inherited disorder or due to impaired excretion of uric acid by he kidneys. The result is a accumulation of sodium biurate crystals in some soft tissues. Tissues of predilection are cartilage,tendon, bursa

Patient usually beyond 40yrs present as

1. Arthritis- metatarsophalangeal joint of big toe being a favourite site,onset of pain is acute, pain is severe

2. Buraitis- commonly of the olecranon bursa

3.Tophi formation deposit of uric acid salt in the soft tissue

Confirmation of diagnosis

Urate crystals in the aspirate from a joint or bursa, high serum uric acid levels

Treatment

NSAIDS,Uricosuric drugs, uric acid inhibitors
