True about eponymous fractures is/are -a) Montegia # is # of the proximal third of ulna with radial head dislocationb) Galeazzi # is # of the distal third of the radius with dislocation of the distal radio-ulnar jointc) Colles # is # at cortico-cancellous junction of the distal-end of redius with dorsal tiltd) Potts # is Trimalleolar ankle #e) Bennet’s # is Oblique intra-articular # of the base of the 1st metacarpal

**Core Concept**
Eponymous fractures are named after the individuals who first described them, often reflecting specific patterns of injury. These fractures are typically characterized by their location, mechanism of injury, and associated complications. Understanding eponymous fractures is crucial for accurate diagnosis and management in orthopedic practice.

**Why the Correct Answer is Right**
Each eponymous fracture has distinct characteristics: Monteggia fracture involves the proximal ulna with radial head dislocation, Galeazzi fracture affects the distal radius with dislocation of the distal radio-ulnar joint, Colles' fracture occurs at the cortico-cancellous junction of the distal radius with dorsal tilt, and Bennett's fracture is an oblique intra-articular fracture of the base of the first metacarpal. Pott's fracture, however, refers to a bimalleolar ankle fracture, not trimalleolar.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because while Monteggia fracture is correctly described, the other options must also be considered for a comprehensive answer.
**Option B:** Incorrect as it does not encompass all correct statements about eponymous fractures.
**Option D:** Incorrect because it does not accurately represent the correct combination of eponymous fractures.

**Clinical Pearl / High-Yield Fact**
Remembering the specific characteristics of each eponymous fracture is key to identifying them on exams and in clinical practice. For instance, Colles' fracture is often associated with a "dinner fork" deformity due to the dorsal tilt of the distal fragment.
