Olecranon Bursitis
                        ==================

- Idiopathic, post-traumatic:  Fluid is pink or bloody, and if spun,
   supernatant is xanthochromic.  WBC averages 878/mm^3; mostly monos.
   Glucose and protein are about 60-80% of serum values.  Mucin clot was fair
   or poor.  [Canoso JJ. Idiopathic or traumatic olecranon bursitis:  clinical
   features and bursal fluid analysis. Arthr Rheum 1977; 20(6):1213.]
 - Septic:  72% of septic bursitis occurs in the olecranon bursa.  70% is
   staph.  80% of gram stains were negative.  Mean WBC was only 6110/mm^3
   after antibiotic therapy. [Pien et al. Orthopedics 1991; 14:981.  A review
   of 47 cases.]
 - Differential elbow temperature the key to distinguishing septic bursitis
   [Smith DL et al.  Arch Intern Med 1989; 149(7):1581.]
 - Treatment of nonseptic bursitis:  NSAIDs only slightly helpful at all;
   injection with steroid (20 mg Depo-Medrol) decreased recurrence rate
   markedly.  [Smith DL et al. Treatment on nonseptic olecranon bursitis:  A
   controlled blind and prospective trial.  Arch Intern Med 1989; 149:2527.]
