Question

Parathyroid autoimplantation takes place in which of the muscle?

• A. Biceps
• B. Triceps
• C. Brachioradialis
• D. Sartorius

Hint:

Think of the forearm muscle used as a host for parathyroid autograft.

Answer 1

The Correct Option is C

Step 1: When every parathyroid gland is excised during a total parathyroidectomy, surgeons preserve gland function by transplanting fragmented parathyroid tissue into skeletal muscle.
Step 2: The forearm is the preferred host. A pocket is fashioned within the brachioradialis, and the diced tissue is seeded there so it can revascularise and resume hormone output.
Step 3: The forearm location keeps the graft superficial and palpable, so a recurrent overactive graft can be trimmed without re-entering the neck. The other listed muscles are not used for this purpose.
\[\boxed{\text{Brachioradialis}}\]
