A patient was seen in the emergency department with a laceration of the skin over the middle phalanx of the right index finger. After carefully examining the patient, the physician decided to suture the wound under a digital nerve block.

  1. The site of the anesthetic injection depended on the following statements except which?

(a) The skin of the right index finger over the middle phalanx is innervated anteriorly by two digital branches of the median nerve.

(b) The skin of the right index finger over the middle phalanx is innervated posteriorly by two digital branches of the superficial radial nerve.

(c) These nerves can easily be blocked by injecting small volumes of anesthetic solution around the base of the finger.

(d) The digital nerves to the fingers are difficult to inject because they are imbedded in tough deep fascia.

(e) Provided that the wound was clean and did not become infected, the healing process should take place without any complications and full return of skin sensation should occur.

 

  1. D.

A 46-year-old man was involved in an automobile accident and sustained a tear of the capsule of the carpometacarpal joint of his right thumb. In view of his history of lung disease, it was decided to repair the laceration under a brachial plexus nerve block. The orthopedic surgeon decided to inject the anesthetic into the brachial plexus below the clavicle.

  1. The injection procedure depended on the following statements except which?

(a) The brachial plexus lies in the axilla and is formed from the anterior rami of C5 through C8 and T1 spinal nerves.

(b) The axillary sheath is formed of deep fascia and surrounds the axillary artery and the brachial plexus.

(c) The arm is abducted to an angle greater than 90° so that the axillary artery could be palpated high up in the axilla.

(d) The anesthetic blocking needle is inserted into the sheath.

(e) The cords and branches of the brachial plexus, including the musculocutaneous nerve, lie within the sheath, and all the branches are blocked by the anesthetic using this approach.

 

Q.30: The following statements concerning this patient are correct except which?

(a) The deep fascia beneath the skin of the palm is thickened to form the palmar aponeurosis.

(b) The distal end of the aponeurosis gives rise to five slips to the five fingers.

(c) Each slip is attached to the base of the proximal phalanx and to the fibrous flexor sheath of each finger.

(d) Fibrous contraction of the slip to the ring finger resulted in permanent flexion of the metacarpophalangeal joint.

(e) The patient had Dupuytren’s contracture.

  1. B. The distal end of the palmar aponeurosis gives rise to four slips, which pass to the four medial fingers.
