title: [Functional and anatomical results after surgical treatment of ruptures of the rotator cuff. 1: Preoperative functional and anatomical evaluation of ruptures of the rotator cuff].
abstract: OBJECTIVE
  In a consecutive series of 98 patients presenting 100 full thickness cuff tears and managed by the same medico-surgical team, the authors studied the correlation between preoperative shoulder function values and the anatomic lesions found at surgery. Predictive factors of tear size were evaluated and any elements that were likely to improve preoperative function were determined so that patients could be best prepared for surgery. The validity of preoperative radiographic assessment of lesions was examined.
  
  
  METHODS
  Prior to surgery, each patient was given the same rehabilitation program, the same arthrotomographic assessment of lesions and each was rated functionally using Constant's scoring method. Preoperative radiographic assessment of lesions showed supra-spinatus tears in 69 per cent, combined supraspinatus and infraspinatus tears in 22 per cent, and tears involving the supraspinatus, infraspinatus and subscapularis in 9 per cent.
  
  
  RESULTS
  The preoperative Constant score averaged 46/100 points. The score was higher when patients had been prepared by preoperative rehabilitation to overcome stiffness. The optimum duration of rehabilitation was found to be 3 months (p < 0.05). Active range of motion was 90 per cent of normal in 84 per cent of cases. The patients in this series therefore underwent surgery more for continuing severe pain (25 per cent) and muscle weakness (86 per cent) than for reduced active motion.
  
  
  CONCLUSIONS
  Examination of the correlations existing between an anatomic lesion and the preoperative rating of shoulder function shows that the Constant preoperative score provides a good prediction of the size of the tear to be repaired (p = 0.0063). The greater the tear size, the lower the preoperative Constant sore is. Active range of motion (especially in abduction and external rotation) and muscular strength are factors with the most predictive value contrary to pain and discomfort which are influenced by tear size.
  
  
  CONCLUSIONS
  Preparing patients suffering full thickness cuff defects through preoperative rehabilitation to overcome stiffness provides the best conditions for surgery. Constant's functional scoring method gives a reproducible and reliable reflection of the anatomic rotator cuff lesion to be repaired. Its use for preoperative rating is useful for determining a reference value for function prior to surgery.
