Which tendon gets involved in Colle’s fracture?
**Core Concept**
Colle's fracture is a type of fracture that occurs at the distal end of the radius bone in the forearm. This fracture is characterized by a displacement of the bone fragments, resulting in a deformity of the wrist. The involvement of specific tendons in Colle's fracture is crucial for its clinical manifestations and treatment.
**Why the Correct Answer is Right**
In Colle's fracture, the extensor pollicis longus (EPL) tendon is often involved due to its close proximity to the fracture site. The EPL tendon runs through the third dorsal compartment of the wrist and is responsible for extending the thumb. When a Colle's fracture occurs, the tendon can become entrapped or damaged, leading to a condition known as EPL tendon rupture or subluxation. This can result in weakness or paralysis of the thumb extension, causing difficulties in performing daily activities.
**Why Each Wrong Option is Incorrect**
**Option A:** The flexor pollicis longus (FPL) tendon is not typically involved in Colle's fracture, as it runs through a different compartment of the wrist and is not as closely related to the fracture site.
**Option B:** The median nerve is not a tendon, but rather a nerve that runs through the carpal tunnel and can be affected by Colle's fracture due to swelling and displacement of bone fragments. However, it is not a tendon that gets involved in the fracture.
**Option C:** The radial nerve is also not a tendon, but rather a nerve that runs through the radial tunnel and can be affected by Colle's fracture due to swelling and displacement of bone fragments. However, it is not a tendon that gets involved in the fracture.
**Option D:** The ulnar nerve is not a tendon, but rather a nerve that runs through the ulnar tunnel and can be affected by Colle's fracture due to swelling and displacement of bone fragments. However, it is not a tendon that gets involved in the fracture.
**Clinical Pearl / High-Yield Fact**
It is essential for clinicians to recognize the involvement of the EPL tendon in Colle's fracture, as this can significantly impact the treatment and prognosis of the patient. A thorough examination of the tendon and wrist function is necessary to determine the extent of the damage and plan appropriate management.
**Correct Answer:** C.
