Joint Innervation

Question 1

SI Joint

Answer 1

Dorsal Rami L5-S3

Question 2

Pubic Symphysis

Answer 2

Several nerves from the sacral plexus, including the pudendal, genitofemoral, and branches of the iliohypogastric and ilioinguinal nerves supply this joint

Question 3

Femeroacetabular Joint

Answer 3

the anterior and posterior aspects of the capsule is innervated by the femoral nerve and roots of the sacral plexus, respectively

Question 4

Tibiofemoral Joint

Answer 4

The femoral, tibial, and common fibular nerves supply innervation to the anterior, posterior, and lateral aspects of the tibiofemoral joint. The obturator and saphenous nerves supply the medial aspect of the joint

Question 5

Patellofemoral Joint

Answer 5

Femoral Nerve

Question 6

Proximal tibiofibular joint

Answer 6

Common fibular nerve

Question 7

Distal tibiofibular joint

Answer 7

Deep fibular, tibial, and saphenous nerves

Question 8

TCJ

Answer 8

Tibial nerve and the deep fibular nerve

Question 9

Subtalar Joint

Answer 9

medial or lateral plantar nerve on the plantar aspect and the deep fibular nerve on the dorsal aspect innervate the joint

Question 10

Transverse tarsal joints

Answer 10

Medial or lateral plantar nerve on the plantar surface of the joint, and the deep fibular nerve on the dorsal aspect of the joint provide innervation

Question 11

Cuneonavicular joint

Answer 11

Medial or lateral plantar nerve on the plantar side of the joint and the deep fibular nerve on the dorsal side

Question 12

Tarsometarsal/intermetatarsal joints

Answer 12

Nerve supply to the plantar aspect of the joints are provided by the lateral and medial plantar nerves. Nerve supply to the dorsum of the foot is from the deep peroneal nerve

Question 13

LE MTP & IP Joints

Answer 13

Digital Nerves

Question 14

SC Joint

medial supraclavicular nerve and the nerve to the subclavius

Question 15

AC Joint

Answer 15

lateral pectoral, axillary, and subcutaneous lateral supraclavicular nerves

Question 16

Glenohumeral Joint

Answer 16

Suprascapular nerve, axillary nerve, lateral pectoral nerve

Question 17

Elbow Joint (all three)

Answer 17

Musculocutaneous, radial, and ulnar nerves

Question 18

Radiocarpal joint

Answer 18

anterior interosseous branch of the median nerve, the posterior interosseous branch of the radial nerve, and the dorsal and deep branches of the ulnar nerve

Question 19

Midcarpal joint

Answer 19

Innervation of this joint includes the median and ulnar nerves on the volar aspect of the hand and the radial nerve on the dorsal aspect of the hand
