BONE & JOINT DISORDERS (ARTHRITIS)
OSTEOARTHRITIS – WHAT HAPPENS
Cartilage (a protein substance) is a spongy material that covers the ends of the bones. It cushions the bones thereby absorbing shocks and preventing them from rubbing against each other.
Any factor (repeated trauma, advanced age, obesity etc.) that causes the breakdown of this protein causes loss of cartilage and results in friction between the bones. This results in loss of joint shape and alignment. The end of the bones thickens and form bony growths called as ‘spurs’ and small bits of cartilage or bone may float within the joint space. This results in stiffness, pain and loss of mobility in joints.
