**Core Concept**
A condylar fracture is a type of mandibular fracture involving the condyle, a crucial part of the jaw joint. The management of condylar fractures depends on the severity of the fracture, including the degree of overlapping and angulation. The primary goal is to restore the normal anatomy and function of the jaw joint.

**Why the Correct Answer is Right**
In cases of condylar fractures with greater than 5 mm overlapping and greater than 37 degree angulation, open reduction and internal fixation (ORIF) is the preferred treatment. This surgical approach allows for accurate reduction and stabilization of the fracture segments, promoting proper healing and minimizing the risk of complications such as malocclusion, temporomandibular joint (TMJ) dysfunction, and facial asymmetry. The use of plates, screws, or other fixation devices helps to restore the normal anatomy and function of the jaw joint.

**Why Each Wrong Option is Incorrect**
**Option A:** Closed reduction and immobilization may be considered for non-displaced or minimally displaced fractures, but it is not suitable for fractures with significant overlapping and angulation.
**Option B:** Arthrocentesis or arthroscopy may be used for the treatment of TMJ disorders, but it is not the primary treatment for condylar fractures with significant displacement.
**Option C:** Conservative management with a soft diet and jaw exercises may be used for non-displaced fractures, but it is not adequate for fractures with greater than 5 mm overlapping and greater than 37 degree angulation.

**Clinical Pearl / High-Yield Fact**
In cases of condylar fractures, the degree of overlapping and angulation is a critical factor in determining the line of treatment. A general rule of thumb is to consider ORIF for fractures with greater than 2-3 mm overlapping and greater than 20-30 degree angulation.

**Correct Answer:** C. Open reduction and internal fixation (ORIF)
