Wrist/Hand Pathology - Cubital Tunnel Syndrome Flashcards
? ? of the ? nerve at the ? tunnel of the ?, medial and ? on the elbow joint in the anatomical position.
This can become compressed if the patient has ? elbows for long periods (e.g. typing at a desk), or due to tight ? bands, ulnar ?, ?
deformities of the elbow or other pathology.
Compression neuropathy ulnar cubital posterior flexed fascial fracture valgus
Presentation;
o Pain near the ? joint , may radiate down ? border of forearm.
o ? and sensory loss over the ? nerve distribution.
o Hand ?, and reduced pinch / ? strength.
o If severe, there will be ? of the hand due to wasting of the ? and ? muscles.
elbow ulnar paraesthesia ulnar cluminess grip clawing hypothenar interosseous
On examination;
o LOOK: ? between the metacarpals, hypothenar ?.
o FEEL: ? around the cubital tunnel.
o MOVE: elbow movements may be ?, and the patient may be unable to actively ? at the IPJs, or actively ?/? the finger.
guttering wasting tenderness limited extend abduct/adduct
TEST: loss of ?, reduced first dorsal ? power, positive ? test along the length of the ? nerve (? to the medial epicondyle then along the ulnar border), positive elbow ? test (sustained elbow ?, with forearm ? and wrist ? will reproduce the symptoms).
sensation interosseous Tinel's ulnar lateral flexion flexion supinated extended
X-rays may show pathogenic ?, or ? conduction studies can be
used to show ? at the elbow.
osteophytes
nerve
slowing
Management;
o Conservative: night-time ?, ?s and ? modification.
o Surgical: simple cubital tunnel ?, or ? ? of the nerve.
