- Screw Tension Band Technique:
- in some cases cancellous bone from the humerus head is removed to allow better impaction;
- insert 4.5 or 6.5 mm cancellous lag screw from the shaft up into the head, just shy of the subchondral bone;
- following screw insertion, figure of 8 tension band wiring (consider No 5 Ethibond) is passed
around the rotator cuff origin on greater tuberosity to a drill hole made in the humeral shaft;
- a second wire is inserted thru both the lesser and greater tuberosities;
- Internal fixation of proximal humerus fractures using the screw-tension band technique.
- Shoulder Replacement:
- need for revision is significantly higher in patients who underwent hemiarthoplasty for trauma
rather than for rheumatoid arthritis;
- upto one half of younger patients undergoing hemiarthroplasty will have subjective
or objective unsatisfactory results;
- technical considerations with fracture:
- IM nailing:
- main disadvantage of IM nailing is that shoulder adduction is required for nail entry into the medullary canal where as
shoulder abduction is often necessary for fracture reduction;
- Is antegrade nailing a proper option in 2- and 3-part proximal humeral fractures?
- avascular necrosis:
- Avascular necrosis of the humeral head treated by core decompression. A retrospective review.
- Vascularity of the humeral head after proximal humeral fractures. An anatomical cadaver study.
- need to categorize the malunion w/ functional and anatomic characteristics;
- look for malposition of the tuberosities, incongruity of the articular surface, malalignment of the articular segment, soft
tissue contractures, rotator cuff tears, instability ect;
- w/ internal rotation contracture, Z lengthening of the subscapularis may be required;
- w/ operative correction of malunion, a good postoperative result requires correction of both soft tissue and osseous
