what is pronator syndrome?
median nerve entrapment at the elbow
how is pronator syndrome differentiated from carpal tunnel syndrome?
decreased sensation over the thenar eminence in the palmar cutaneous branch of the median nerve
a pronator compression test reproduces pain/tingling in the radial fingers. what is the lesion?
pronator syndrome - median nerve entrapment at the elbow
a patient experiences volar arm pain and radial digit pain with resisted flexion of the PIP joint of the middle finger. what does this cause compression of? what is the condition?
compression of the FDS heads ; pronator syndrome
a patient with history of FOOSH has a flake sign on XR of the elbow. what is this and what does it signify?
small bony avulsion fragment from the olecranon - pathognomonic for triceps rupture
for non surgical management of low grade partial tear of the distal triceps tendon, how should the elbow be immobilized?
30 degrees flexion
what is the pathophysiology of valgus extension overload?
repetitive forceful shearing of the olecranon within its fossa causing chrondromalacia and olecranon osteophyte formation
physical therapy for valgus extension overload will focus on what?
eccentric strengthening of the wrist flexors
what is the management for the majority of olecranon stress fractures?
non surgical
