Dislocation of  joints

 

 

 

 

First try to understand what are the factors which provide stability to joints.

1.      Design 2. ligament 3. muscles

Design means the shape of  articulating surfaces of joints provide more stability to  joints for example hip joint is more stable because of cup and socket like arrangement, however shoulder socket is shallow (known as glenoid) while a ball of humerous rotates over it so it is a poor design that’s why it dislocates more easily. God made this so, so that more range of movements can be possible at shoulder joint.

Ligaments plays vital role in providing strength to fingers etc but in case of shoulder they are not so important.

Muscle surrounding a joint provide greater strength to it, even in worst conditions muscle contracts and reduces stress, so they are dynamic stabilizers of joint.

Dislocation is the term used when articular surfaces are wholly displaced, there is no contact in between them, if they are in contact condition is known as subluxation.

Dislocation can be congenital when it is dislocated at birth eg congenital dislocation of hip, it can be traumatic or pathological.

Injury is  main cause of it, however some pathology like cancer or infection which damage articular surfaces or ligaments also caused dislocations.

Complications of dislocations are like myositis ossificans, recurrence, persistent instability, joint stiffness, osteoarthritis and  avascular necrosis.

Treatment: treatment depends upon its type, Acute Traumatic Dislocations requires conservative treatment, however operative methods also required in fracture dislocations and in late detected cases.

Old unreduced dislocations also require operative reduction.

Recurrent dislocations require reconstructive procedures.
