Poland's syndrome

a condition in which a person is missing the pectoralis major muscle on one side and also has some skeletal abnormalities is known as

cause by inflammation of flexor retinaculum-decreasing size of carpal tunnel median nerve

a patient complains of carpel tunnel syndrome. explain the condition to the patient. what commonly causes the condition? which nerve is usually compressed?

results from repetitive use of the superficial muscles of the forearm common flexor tendon

a patient complains of golfers elbow. what causes this condition? which specific tendon is strained?
