Gout is inflammation of joints due to accumulation of uric acid crystals.
Osteoporosis is an age-related disorder characterised by decreased bone mass and increased chances of fractures. Decreased levels of oestrogen is a common cause.
In tetany rapid spasms occur in muscles due to low Ca²⁺ in body fluid.
Muscular dystrophy is progressive degeneration of skeletal muscle mostly due to genetic disorder.
