An injury to the spinal accessory nerve will affect which of the following movements?
Lateral rotation of the arm
Adduction of the arm at the glenohumeral joint
Protraction of the scapula
Upward rotation of the scapula
Depression of the scapula
The spinal accessory nerve innervates trapezius. The entire muscle will retract the scapula. However, its upper and lower fibres act together to upwardly rotate it.
What is the carpal tunnel? What is contained within it? (you’re looking for 10 items you might want to draw a simple diagram to help)
The carpal tunnel is created by a thick band of retinacula spanning between the carpal bones of the wrist, creating a tunnel. Passing through this tunnel are the tendons of

A junior doctor sees two patients with ulnar nerve palsy in quick succession. The first patient has an injury of the wrist and presented with a severe ‘claw-like’ deformity of the hand. The second patient has an injury at the elbow and has a similar, but less severe deformity. Why is the presentation paradoxically less severe at the more proximal site of injury?
Retained innervation of flexor digitorum profundus muscle
Retained innervation of the flexor digitorum superficialis mucle
Denervation of flexor digitorum superficialis muscle
Denervation of flexor digitorum profundus muscle
Less severe injury of ulnar nerve due to protection from surrounding muscles

Elizabeth is a 44 year old female who felt a lump in her right breast which over a 2 month period increased in size. Examination of the breast revealed a large, irregular mass measuring 8x6cm occupying the central and upper outer quadrant of the breast. In addition there were 2 lymph nodes that could be palpated in her right axilla which were slightly tender on palpation. The left breast and axilla were unremarkable. The supracalvicular, cervical and inguinal lymph nodes were not palpable. Elizabeth underwent a radical mastectomy and axillary lymph node clearance. She also had an immediate breast reconstruction using a latissimus dorsi flap. After radiotherapy and chemotherapy there were no apparent complications until 3 days after the last radiation therapy, when she reported right shoulder pain and decreased range of movement. 2 weeks later when there was no improvement she was referred for evaluation. She had normal strength and function in the cervical and upper extremity muscles. However, she exhibited nearly complete absence of function of the serratus anterior muscle on the right side. The patient could not actively abduct the right arm more than 60 degrees. There was gross winging of the scapula on the right side most evident on forward flexion and on pushing forward against resistance.
- What are the actions of latissimus dorsi for both the upper and lower limbs (look at its insertions on both the humerus and pelvis)?*
- What does serratus anterior do? Therefore, explain sign “winging of the scapula” and the lack of abduction above the horizontal plane (note the deltoid and the supraspinatus are not affected in this case).*
Latissimus dorsi acts on the upper limb to bring about extension, and medial rotation. However is the upper limbs are in a fixed position (for example above the head holding onto a rail) latissimus dorsi pulls the trunk towards the upper limb (a pull up). It is an important climbing muscle.
- Serratus anterior protracts and rotates the scapula, and at rest holds the scapula flat to the back. Weakness in this muscle can therefore cause winging of the scapula.*
- Abduction of the shoulder requires rotation of the scapula, so a weakness in this muscle will result in weaker abduction.*

A 24-year-old female is rushed to the emergency department after sustaining an injury during training. She is a competitive powerlifter and her training involves rapid, explosive movements with heavy weights.
On examination, weakness of knee flexion, and some localised knee swelling is noted. The emergency doctor is concerned about the detachment of the biceps femoris from the site of insertion and requests an orthopaedic review.
Which of the following is the site of insertion of the long and short head of biceps femoris?
Medial surface of proximal tibia
Tibial tuberosity
Head of the fibula
Medial tibial condyle
Lesser trochanter
