AB  - BACKGROUND: Humeral stem lucencies are uncommon after uncemented anatomic total 
      shoulder arthroplasty (aTSA), and their clinical significance is unknown. This 
      study compares clinical outcomes of aTSA with and without humeral stem lucencies. 
      METHODS: Two-hundred eighty aTSAs using an uncemented grit-blasted 
      metaphyseal-fit humeral stem between 2005 and 2013 were retrospectively evaluated 
      for radiographic humeral stem lucencies. All shoulders were evaluated at a 
      minimum 5-year follow-up from a multicenter database. Clinical outcomes included 
      range of motion (ROM) and American Shoulder and Elbow Surgeons Standardized 
      Shoulder Assessment Form (ASES) score, Constant score, University of 
      California-Los Angeles Shoulder Score (UCLA), Simple Shoulder Test (SST), and 
      Shoulder Pain and Disability Index (SPADI) scores. Postoperative radiographs were 
      evaluated and complications were recorded. RESULTS: Two-hundred forty-three 
      humeral stems showed no radiolucent lines. Among the 37 humeral stems with lucent 
      lines, lines were most common in zones 8, 4, 7, and 3. Preoperative ROM and 
      functional outcomes were similar between groups. Postoperative change in outcomes 
      exceeded the minimal clinically important difference (MCID) for all ROM and 
      outcomes in both groups. Postoperative change between groups showed no 
      significant difference in ROM or outcome scores, but improved mean abduction 
      exceeded the MCID in the patients without humeral lines. The complication rate 
      after omitting patients with humeral loosening was higher in patients with 
      humeral lucencies, as was the revision rate. There was also a higher 
      glenoid-loosening rate in patients with humeral lucencies. CONCLUSION: Humeral 
      lucent lines after uncemented stemmed aTSA have a small negative effect on ROM 
      and functional outcomes compared with patients without lucent humeral lines, 
      which may not be clinically significant. The complication and revision rates were 
      significantly higher in patients with humeral lucencies.
