Example Questions

Example Question #3 : Help With Bone Injuries And Disorders

Osgood-Schlatter's is characterized by repeated avulsion fractures of which bone?

Possible Answers:

Ischium

Tibia

Ilium

Patella

5th metatarsal

Correct answer:

Tibia

Explanation:

Although bony prominences on the other bones listed are common sites for avulsion fractures, Osgood-Schlatter's disease refers to the repeated avulsion of the tibial tuberosity, which can occur during growth spurts.

Example Question #101 : Injuries And Disorders

Following anterior dislocation of the humerus, the posterolateral posrtion of the humeral head can become injured. What is the name for this type of injury?

Possible Answers:

McLaughlin lesion

Bankart lesion

Reverse Hill-Sachs lesion

Hill-Sachs lesion

SLAP lesion

Correct answer:

Hill-Sachs lesion

Explanation:

(Superior Lateral Anterior Posterior) SLAP and Bankart tears are injuries to the glenoid labrum. Reverse-Hill Sachs and McLaughlin lesion are synonymous, however they are injuries to the anteromedial portion of the humeral head, and are caused by posterior dislocation of the humerus.

Example Question #1477 : Human Anatomy And Physiology

A Monteggia fracture is an injury to bone?

Possible Answers:

Femur

Talus

Patella

Fibula

Ulna

Correct answer:

Ulna

Explanation:

A Monteggia fracture is a fracture-dislocation injury that involves a fracture of the proximal ulna, and dislocation of the proximal radius.

Example Question #1474 : Human Anatomy And Physiology

Which of the following describes a grade V Salter-Harris fracture?

Possible Answers:

Fracture through the epiphyseal plate, with small fracture through metaphysis ("chip fracture")

Fracture through the epiphyseal plate and epiphysis

Compression injury to epiphyseal plate

Fracture extending from the epiphysis, through the epiphyseal plate, and into the metaphysis

Transverse fracture through the epiphyseal plate

Correct answer:

Compression injury to epiphyseal plate

Explanation:

A Salter-Harris type V fracture is a compress ion injury of the epiphyseal plate. The other choices listed are type I is a transverse fracture through the epiphyseal plate. Type IV is a fracture extending from the epiphysis, through the epiphyseal plate, and into the metaphysis. Type III is a fracture through the epiphyseal plate and epiphysis. Type II is a fracture through the epiphyseal plate, with small fracture through metaphysis ("chip fracture").

Example Question #9 : Help With Bone Injuries And Disorders

An open-book fracture describes an injury to which body region?

Possible Answers:

Pelvis

Wrist complex

Cervical spine

Ankle complex

Elbow complex 

Correct answer:

Pelvis

Explanation:

An open book fracture is an injury to the pelvis. In this injury, the pubic symphysis is disrupted, causing the pelvis to look like an open book.

Example Question #1 : Help With Bone Injuries And Disorders

Which of the following diseases is not associated with damage to bones?

Possible Answers:

Osteogenesis imperfecta

Paget's disease

de Quervain syndrome

Pott's disease

Correct answer:

de Quervain syndrome

Explanation:

Paget's disease is a bone disease characterized by rapid bone degradation, and rebound bone growth however, the bone is laid bone in a disorganized manner and is prone to further degeneration. Pott's disease is characterized by destruction of thoracic vertebra, secondary to tuberculosis infection. Osteogenesis imperfecta is a congenital disorder caused by abnormalities in type I collagen production, that makes the patient prone to fracture. de Quervain syndrome is also known as de Quervain tenosynovitis, and is characterized by irritation to the sheath covering the extensor pollicis brevis and abductor pollicis longus tendons.

Example Question #102 : Injuries And Disorders

If you read a patient’s medical history, and saw that she had gunstock deformity, which joint would you examine for this deformity?

Possible Answers:

Wrist

Hip

Knee

Elbow

Correct answer:

Elbow

Explanation:

A gunstock deformity (cubitus varus) refers to a deformity at the elbow joint, where the distal forearm is deviated medially (compared to typical anatomical alignment). Conversely, if a patient's distal forearm is deviated excessively laterally, she is said to demonstrate cubitus valgus. Cubitus varus is most commonly caused by supracondylar fractures of the humerus. Fortunately, this deformity is largely cosmetic in nature, and causes few functional limitations. 

Example Question #103 : Injuries And Disorders

You’re reading your patient’s medical history, and find he suffered a Monteggia fracture. Based on this information, which joint would expect to be affected?

Possible Answers:

Talocrural joint

Glenohumeral joint

Proximal radio-ulnar joint

Acromioclavicular joint

Correct answer:

Proximal radio-ulnar joint

Explanation:

A Monteggia fracture refers to a fracture of the shaft of the ulna, and a concurrent dislocation of the head of the radius. Accordingly, this type of fracture-dislocation injury also affects the humeroradial joint (part of the elbow complex). This type of injury is often caused by falling on an outstretched arm, which could affect the glenohumeral and acromioclavicular joints as well.

Example Question #103 : Injuries And Disorders

Which of these refers to an avulsion injury to the thumb?

Possible Answers:

Gamekeeper’s fracture

Mallet finger

Boxer’s fracture

Pott’s fracture

Correct answer:

Gamekeeper’s fracture

Explanation:

A gamekeeper's fracture refers to an avulsion injury at the base of the proximal phalanx of the thumb, secondary to a rupture of the ulnar collateral ligament of the thumb. Mallet finger refers to a rupture of one of the extensor digitorum tendons, at the distal interphalangeal joints. A boxer's fracture is a fracture of one of the metacarpals. A Pott's fracture is a type of ankle fracture involving the medial and lateral malleoli.

Example Question #104 : Injuries And Disorders

Which of the following injuries to the humerus occurs after an anterior dislocation of the glenohumeral joint?

Possible Answers:

Reverse Hill-Sachs lesion

Bankhart lesion

SLAP lesion

Hill-Sachs lesion

Correct answer:

Hill-Sachs lesion

Explanation:

A Hill-Sachs lesion occurs after the head of the humerus abuts that glenoid rim of the scapula, injuring the articular cartilage, when the humerus is dislocated anteriorly. If the humerus is dislocated posteriorly, it can result in a reverse Hill-Sachs lesion. SLAP and Bankhart lesions are injuries of the glenoid labrum and thus, are not viable answers to this question.
