HBS 1.1 Test: Fracture Analysis and Treatment

A 15-year-old soccer player falls and presents with pain and swelling in the forearm. The X-ray shows a fracture with the bone broken into three distinct pieces. Which type of fracture is most likely present, and what evidence supports your conclusion?

• Greenstick fracture; because the bone is bent and partially broken, common in children.

• Comminuted fracture; because the bone is broken into multiple pieces.

• Spiral fracture; because the break spirals around the bone.

• Transverse fracture; because the break is straight across the bone.

A patient presents with a swollen, deformed leg after a fall. The X-ray reveals a diagonal break across the shaft of the femur. Using diagnostic reasoning, which type of fracture is this, and what mechanism of injury is most likely?

• Transverse fracture; caused by a direct blow.

• Oblique fracture; caused by an angled force.

• Greenstick fracture; caused by bending.

• Compression fracture; caused by axial loading.

Given an X-ray showing a bone with a break that spirals around the shaft, what reasoning would you use to determine the cause of this fracture, and what is the most likely diagnosis?

• The fracture is likely due to a twisting injury; diagnosis is spiral fracture.

• The fracture is likely due to a direct blow; diagnosis is transverse fracture.

• The fracture is likely due to compression; diagnosis is compression fracture.

• The fracture is likely due to repetitive stress; diagnosis is stress fracture.

A 9-year-old child presents with a partial break in the radius after falling off a bike. The X-ray shows the bone is bent with a crack on one side. What type of fracture is this, and what evidence supports your diagnosis?

• Greenstick fracture; because the bone is bent and only partially broken.

• Comminuted fracture; because the bone is in several pieces.

• Oblique fracture; because the break is at an angle.

• Transverse fracture; because the break is straight across.

A patient with a history of osteoporosis presents with sudden back pain after lifting a heavy object. The X-ray shows a vertebral body that appears crushed. Using diagnostic reasoning, what type of fracture is this and what is the most likely cause?

• Spiral fracture; caused by twisting.

• Compression fracture; caused by weakened bone structure.

• Greenstick fracture; caused by bending.

• Oblique fracture; caused by angled force.

A patient presents with a displaced mid-shaft humerus fracture. Considering the fracture type and location, which repair method would you recommend and why?

• Cast immobilization; because it is sufficient for all humerus fractures.

• Open reduction and internal fixation (ORIF); because the fracture is displaced and needs precise alignment.

• Traction; because it is the fastest method.

• External fixation; because it is always preferred for humerus fractures.

A 12-year-old presents with a non-displaced distal radius fracture. What is the most appropriate initial treatment plan, and what is your reasoning?

• Immediate surgery; because all fractures require surgical intervention.

• Cast immobilization; because the fracture is non-displaced and can heal with immobilization.

• Traction; because it is the standard for all fractures.

• No treatment; because it will heal on its own.

A patient with a comminuted tibial fracture is at risk for complications. Which repair method would you choose and what factors influence your decision?

• Cast immobilization; because it is always sufficient.

• Open reduction and internal fixation (ORIF); because it allows for stabilization of multiple bone fragments.

• No intervention; because the bone will heal naturally.

• Traction; because it is the fastest method.

After surgical repair of a femoral shaft fracture, what rehabilitation strategy would you recommend to promote optimal recovery, and why?

• Immediate full weight-bearing; because it speeds up healing.

• Gradual weight-bearing with physical therapy; to restore strength and mobility safely.

• Complete bed rest for several months; to avoid complications.

• No rehabilitation; because the bone will heal on its own.

A patient presents with a stress fracture in the metatarsal. What diagnostic reasoning would you use to confirm this diagnosis, and what is the best initial treatment plan?

• Rely on clinical symptoms and X-ray; recommend rest and limited weight-bearing.

• Ignore symptoms; recommend immediate surgery.

• Use only X-ray; recommend full activity.

• Use only clinical symptoms; recommend no treatment.
