- Discussion:
- recurrent rotator cuff tear:
- ref:
Mode of failure for rotator cuff repair with suture anchors identified at revision surgery
- deltoid injury:
- may occur from
axillary nerve palsy or from avulsion of deltoid off the acromion;
- detached anterior deltoid may be diagnosed by careful palpation on physical exam;
- consider
EMG to determine whether the injury is an
neuropraxia or neurotmesis;
- superior migration of the humeral head:
- is more apt to occur w/ massive rotator cuff tears;
- may occur due to excision of CA ligament and excessive acromioplasty;
- missed diagnosis
- nerve palsy:
- w/ failed rotator cuff surgery, consider obtaining an
MRI of the shoulder, to
evaluate for space occupying lesion causing
suprascapular nerve palsy;
- also consider
EMG:
- occult instability: (
anterior or
multi-directional)
-
biceps tendonitis
-
AC joint arthrosis:
- os acromiale:
- ref:
Os acromiale: anatomy and surgical implications.
- recurrent impingement:
-
cervical spondylosis:
-
reflex sympathetic dystrophy
-
thoracic outlet syndrome
- glenohumeral osteoarthritis;
- Management Suggestions:
- revision acromioplasty in worker's compensation patients is unlikely to improve symptoms;
- if a specific diagnosis can be made (either recurrent impingement or other), then a second
operation may be indicated;
