title: Hemiarthroplasty for comminuted proximal humeral fractures.
abstract: OBJECTIVE
  To evaluate early functional outcomes of hemiarthroplasty for 3- or 4-part proximal humeral fractures.
  
  
  METHODS
  16 men and 11 women aged 27 to 83 (mean, 56) years underwent hemiarthroplasty for comminuted 3-part (n=13) or 4-part (n=14) proximal humeral fractures. All the patients reported normal shoulder function prior to injury. The range of shoulder motion and muscle power were evaluated, as were subjective pain and satisfaction (using the UCLA scoring system).
  
  
  RESULTS
  At the final follow-up, the mean maximum abduction was 111º (SD, 47º; range, 30º-180º), and the mean maximum forward flexion was 143º (SD, 41º; range, 45º-180º). All patients had radiographic union of the tuberosities. The mean UCLA score was 28; 21 patients attained good-to-excellent scores (≥27), whereas 6 attained lower (fair-to-poor) scores. The mean UCLA score was higher in patients aged <60 (n=13) than those who were older (n=14) [30 vs. 26, p=0.008] and in patients operated after 7 days (n=6) than those operated before 7 days (n=21) [32 vs. 27, p=0.02], but did not differ significantly in terms of gender and fracture type and side. Patient age and gender, fracture type, and injury-to-surgery interval did not have a significant impact on maximum forward flexion and abduction.
  
  
  CONCLUSIONS
  Early functional outcomes of hemiarthroplasty for comminuted proximal humeral fractures is good in medically fit and cooperative patients.
