When taken to theatre for reduction and fixation of the fracture, the surgical team recalls that additionally a nerve is at risk when pins are passed through the medial epicondyle of the humerus. Which nerve is most at risk here?

A 27-year old patient on the orthopaedic ward is asked to be reviewed by the orthopaedic intern due to “pins and needles” following being fitted with a circumferential plaster for a tibial fracture. She complains of altered sensation over the dorsum of the foot, including in the 1st web space. Which nerve is likely being compressed?

An 8-year old child presents with the following fracture and an inability to flex the interphalangeal joint of their thumb. Which neurovascular structures are most likely compromised in this clinical scenario, at the site of the fracture?

All of the following structures are located in the posterior mediastinum, except:

The patient is later taken to theatre to repair the fractured clavicle. In the immediate postoperative period, whilst sitting elevated at 45 degrees, the patient vomits and there is concern for aspiration of the vomitus into the lungs. Where would any aspirated material most likely lodge and therefore which section of lung may be affected?

A 25-year old is brought to the ED following a motorbike accident. In addition to an obviously deformed clavicle, there are clear contusions to the chest wall, and therefore a CT scan is performed to rule out lung injury and rib fractures. The following image is obtained:

In the above radiograph, the right heart border is partially obscured. Which structure corresponds to the majority of the right heart border?

An 83-year-old patient is admitted to hospital for surgery following a right neck of femur fracture. On day 7 post-op she becomes hypoxic, dyspnoeic and tachycardic, necessitating urgent medical review.  On examination, she has dullness to percussion in the right mid-anterior and right mid-lateral lung fields and reduced bilateral breath sounds.  An urgent chest X-ray is performed (shown below).

Based on the clinical information and the chest X-ray provided, what lobe(s) of the lung is(are) affected?

During further dissection of the lung hilum, there is an injury to structure corresponding to label “B”, necessitating its ligation. Following injury to structure B, venous drainage of the majority of the bony thorax will then occur via the:
