    THIS REPORT IS BEING FILED AFTER THE REVIEW OF THE FOLLOWING JOURNAL ARTICLE: SARAHRUDI K ET AL (2009). SURGICAL TREATMENT OF PATHOLOGICAL FRACTURES OF THE SHAFT OF THE HUMERUS. THE JOURNAL OF TRAUMA INJURY, INFECTION, AND CRITICAL CARE. VOLUME 66. PAGES 789-794. (AUSTRIA). THIS STUDY AIMS TO REPORT AN EXPERIENCE WITH THE TREATMENT OF PATHOLOGIC FRACTURES OF THE HUMERUS SHAFT AND TRY TO CLARIFY INDICATIONS FOR DIFFERENT SURGICAL PROCEDURES. BETWEEN 1992 AND 2007, 54 PATIENTS WHO WERE TREATED FOR PATHOLOGIC FRACTURE OF THE HUMERUS DIAPHYSIS WERE INCLUDED IN THE STUDY. THERE WERE 38 WOMEN AND 16 MEN WITH A MEAN AGE OF 66.5 +/- 12.7 YEARS. 15 PATIENTS WERE TREATED CONSERVATIVELY DUE TO SERIOUS MEDICAL PROBLEMS AND POOR HEALTH CONDITIONS NOT ALLOWING AN OPERATION. THE REMAINING 39 PATIENTS WITH A TOTAL OF 41 FRACTURES UNDERWENT OPERATIVE TREATMENT. A TOTAL OF 22 OPEN REDUCTION AND INTERNAL FIXATION (ORIF) PROCEDURES IN 21 PATIENTS AND 19 INTRAMEDULLARY (IM) FIXATIONS IN 19 PATIENTS WERE PERFORMED (ONE PATIENT RECEIVED ORIF ON ONE HUMERUS AND IM FIXATION ON THE OTHER HUMERUS). 15 PATIENTS WERE IMPLANTED WITH AN UNKNOWN SYNTHES SOLID HUMERAL NAIL (UHN) FOR IM FIXATION WHILE THE REST WERE FIXATED USING A COMPETITOR¿S DEVICE. FOR INTERNAL PLATE FIXATION, 18 PATIENTS WERE IMPLANTED WITH AN UNKNOWN SYNTHES DYNAMIC COMPRESSION PLATE, 2 PATIENTS WERE IMPLANTED WITH AN UNKNOWN SYNTHES LOCKING COMPRESSION PLATE, AND 1 PATIENT WAS IMPLANTED WITH AN UNKNOWN SYNTHES PROXIMAL HUMERAL INTERNAL LOCKING SYSTEM (PHILOS) PLATE AS WELL AS AN UNKNOWN SYNTHES Y-PLATE. THE MEDIAN SURVIVAL AFTER THE OCCURRENCE OF THE PATHOLOGIC FRACTURE WAS 2.8 MONTHS (RANGE, 0.2¿ 66.7) FOR ALL PATIENTS. THE SURVIVAL RATE FOR THE SERIES OF 54 PATIENTS WAS 0.24 AFTER 1 YEAR AND 0.09 AFTER 2 YEARS FROM THE INITIAL FRACTURE. ALL THE LIVING PATIENTS ARE AMONG THOSE WITH ORIF. THE AUTHORS DID NOT SPECIFY WHICH DEVICES WERE IMPLANTED FOR EACH PATIENT. THUS, COMPLICATIONS WILL BE REPORTED AS FOLLOWS: UNKNOWN PATIENTS SHOWED NO SIGN OF CONSOLIDATION OR BRIDGING ON THE RADIOGRAPHS TAKEN AT A MEAN TIME OF 14.8 WEEKS AFTER THE OPERATION. 1 PATIENT HAD A FAIR RELIEF OF PAIN AFTER INTERNAL FIXATION. 4 PATIENTS HAD POSTOPERATIVE IATROGENIC RADIAL NERVE PALSY AFTER INTERNAL FIXATION. 2 PATIENTS WERE UNABLE TO RECOVER FROM THIS NEUROLOGIC DEFICIT IN WHICH 1 OF THESE PATIENTS RADIAL NERVE PALSY WAS CAUSED BY A POSTOPERATIVE HEMATOMA AND REQUIRED REOPERATION. THE NERVE, HOWEVER, DID NOT RECOVER AND THE NEUROLOGIC DEFICIT REMAINED UNTIL THE PATIENT¿S DEATH, 2 WEEKS AFTER THE REVISION SURGERY. 1 PATIENT RECOVERED COMPLETELY 2 MONTHS AFTER REVISION. 1 PATIENT REGAINED COMPLETE RECOVERY AT 3 WEEKS AFTER THE OPERATION. 1 PATIENT HAD A STRESS RISER LED TO REFRACTURE OF THE HUMERUS AT THE DISTAL END OF THE DYNAMIC COMPRESSION PLATE 83 DAYS AFTER PRIMARY STABILIZATION AND REQUIRED REOPERATION. 1 PATIENT STILL HAD PAIN AT THE LAST FOLLOW UP AFTER INTRAMEDULLARY FIXATION. 2 PATIENTS HAD INADEQUATE INTRAMEDULLARY STABILIZATION RESULTING IN INSTABILITY AND NONUNION. 1 OF THE PATIENTS HAD AN INCORRECT INDICATION FOR IM STABILIZATION SINCE THE FRACTURE WAS LOCATED AT THE DISTAL ONE-FIFTH OF THE HUMERUS AND COULD NOT BE SUFFICIENTLY STABILIZED BY THE NAIL. 1 PATIENT HAD A LOCAL PROGRESSION OF THE RESIDUAL TUMOR 200 DAYS AFTER INTRAMEDULLARY FIXATION. THE PATIENT REQUIRED A FOLLOWING PROCEDURE WITH TUMOR CURETTAGE AND CEMENTATION.
