Elbow Common Presentations: Dislocation & Instability Flashcards
michigan hand outcomes questionnaire (MHQ)
- hand specific outcome measure
- 37 items on 6 scales
- higher score = better hand function
what are the 6 scales on the MHQ
- overall hand function
- ADLs
- work performance
- pain
- aesthetics
- satisfaction with hand function rated on a 5 point likert scale
what is part of the observation with wrist/hand problems
- prominent distal ulna
- ulnar drift
- finger deformities
- myelopathy hand
- posture
prominent distal ulna
distal radial ulnar joint instability
ulnar drift
- RA
- fingers drift toward ulna
common finger deformities
swan neck
boutonniere
mallet finger
myelopathy hand
- red flag
- muscle wasting of hand
- loss of power in fingers
- due to cervical spinal cord pathology/compression
elbow dislocation
position of olecranon relative to the humerus
most common dislocation at the elbow
- posterior, especially posterolateral
- anterior and radial head dislocations account for 1-2%
MOI of elbow dislocation
traumatic
FOOSH
complete dislocation results in..
results in tear of UCL and possible tear of joint capsule, LCL, brachials and/or wrist flexor and extensor muscles
integument of elbow dislocation
swelling
deformity
interventions for elbow dislocation
- if stable after relocation..
- strengthen muscles around the joint
- PROM
- proprioception
what provides majority of stability at the elbow joint
humeroulnar and humeroradial, additional support is by ligaments and muscle
MOI of elbow instability
traumatic FOOSH
repetitive use in throwing and overhead athletes
history in elbow instability
- prior dislocations
- clicking, poppingg, clunk, locking, catching
