The lumbar region of the vertebrae is known for its high mobility and ability to support body weight. If it receives inappropriate signals during development and fuses with the sacrum, it will result in a loss of mobility in the individual.

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").

End range ankle eversion tenses the deltoid ligament (medial collateral ligament of the ankle). However, at the extremes of ankle eversion, the high tensile strength of the deltoid ligament can cause the medial malleolus to avulse from the tibia. During inversion, this ligament is not tense.

(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.

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.

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.

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.

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.

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.

Osteophytes (bone spurs) are bony projections that form at joints. Osteophytes occur when there are changes to bone formation via aging, mechanical instability, degeneration, and disease, including arthritis (which is the most common cause of osteophyte formation). Osteophytes form naturally on the spine via degeneration of the vertebrae with aging. Osteophytes do not cause pain, but may impinge on nerves which will lead to pain, and/or numbness and tingling sensations. Chondrocytes are cartilage cells.
Enthesophytes are bony projections that form at ligament or tendon attachments.

Osteoporosis is a breakdown of bone, commonly due to a lack of calcium, which is typically lost faster in females due to a menstruation cycle, and chronic breakdown with age. Also, females have less bone density to begin with.
