Episode notes
Teaching Ulnar Stability With Personal Demo
- Chris teaches ulnar nerve stability by having trainees examine his own subluxating ulnar nerve.
- He demonstrates placing the thumb on the medial epicondyle and pulling the nerve anterior while flexing and extending the elbow.
Why He Switched From Hypothenar Flaps
- Early in practice Chris photographed many hypothenar fat pad flaps and found they often don't reach proximal compression sites.
- That led him to favor distal-forearm perforator-based adipofascial flaps for reliable coverage.
Look Proximal For Incomplete Carpal Releases
- In persistent CTS after release, suspect incomplete proximal release under the antebrachial fascia near the wrist crease.
- Examine for scarring after distal radius fracture or forearm trauma as a common cause of persistent symptoms.
