Purpose. 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 111° (SD, 47°; range, 30°–180°), and the mean maximum forward flexion was 143° (SD, 41°; range, 45°–180°). 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

Purpose. To evaluate the correlation of kyphosis and wedge angles with pain relief and functional outcome after percutaneous vertebroplasty (PV). Methods. 15 men and 19 women aged 41 to 85 (mean, 62) years who presented with osteoporotic wedge compression fractures of the dorsolumbar spine below T5 and had failed conservative treatment were included. Patients were assessed before and one year after PV. Kyphosis and wedge angles were measured on standardised radiographs. Pain and function were assessed using the visual analogue scale (VAS) score and the Ronald Morris Disability Questionnaire (RMDQ) score, respectively. Patients were dichotomised based on their preoperative kyphosis (≤10° vs. >10°) and wedge angles (≤7° vs. >7°). Outcomes were classified as excellent, fair, and poor in terms of VAS scores (6) and RMDQ scores (16). Correlations between the kyphosis and wedge angles and VAS and RMDQ scores were assessed. Results. VAS and RMDQ scores correlated positively with the kyphosis and wedge angles; the highest correlation was between the VAS score and kyphosis angle ( r =0.93). A significantly greater proportion of excellent outcomes (in terms of RMDQ and VAS scores) were noted in patients with preoperative kyphosis and wedge angles of ≤10° and ≤7°, respectively. Conclusion. PV is a viable treatment for vertebral compression fractures with regard to pain relief and improvement of function. Preoperative kyphosis and wedge angles were predictive of post-PV outcomes in terms of VAS and RMDQ scores.
