• Research summary

  At present, the 3 common treatment options for displaced 3/4 part fracture proximal humerus in patients aged above 70 years
  1. Non operative in sling
  2. Open reduction and internal fixation
  3. Hemi-arthroplasty
  Reverse geometry shoulder replacement is a surgery presently performed mostly ELECTIVE for shoulders with irreparable rotator cuff .

  Ultrasound scanning has demonstrated that 31% in the seventh decade of life have a rotator cuff tear (Tempelhof S, Rupp S, Seil R: Age-related prevalence of rotator cuff tears in asymptomatic shoulders. (J Shoulder Elbow Surg 1999, 8:296-299).The function of the rotator cuff is further compromised by the fracture which detaches whatever cuff that remains.
  Hence results of hemi-arthroplasty and internal fixation which requires an intact rotator cuff to work, is compromised. ( AGE AS PERCENTAGE)

  Reverse –Geometry Shoulder Replacement (RGSR), is designed to work in presence of torn rotator cuff .Hence RGSR is ideally suited to restore function and address both problems of fracture and non-functioning cuff.

  We plan to conduct a RCT to compare functional outcomes following the 2 surgical interventions ( hemi-arthroplasty vs RGST) for 3 &4 part fractures of proximal humerus in patients aged more than 70 years.
