PURPOSE
The major pelvic trauma results in high mortality with associated fatal other injuries. During early stage of resuscitation, multidisciplinary approach is essential to improve the survival and outcomes. This study aims to report the effect and positive outcome of the trauma team approach on the management of hemodynamically unstable pelvic bone fracture.
METHODS
This retrospective review included all patients with hemodynamically unstable pelvic bone fracture admitted between March 2007 and December 2015. Patients were divided into group A, which comprised those admitted before the trauma team approach was started, and group B, which comprised those admitted after the approach was started. The advanced trauma life support protocol was followed for all patient. The comparisons between the two groups were based on medical records. Study variables included demographics, initial vital sign, injury severity score, fracture type, and injury mechanism. We analyzed the outcomes in each group with respect to the time interval for doctors' arrival, total length of stay in the emergency department (ED), time interval for computed tomography evaluation, 24-hour mortality, time interval for definitive fixation, and definitive fixation in the time-window of opportunity.
RESULTS
Fifty-three patients met the inclusion criteria. No statistically significant differences in demographic data existed between the two groups. The time interval for doctors' arrival (min, 63.09±50.48 vs 21.48±17.75; p=0.038) and total length of stay in the ED (min, 269.33±105.96 vs 115.49±56.24; p=0.023) were significantly improved. The 24-hour mortality was not significantly different between the two groups.(%, 14.3 vs 12.0; p=1.000) However, the time interval for definitive fixation and definitive fixation in the time-window of opportunity showed better results.
CONCLUSION
The trauma team approach has positive effects, which include initial resuscitation through multidisciplinary approach and shortening the time interval to definitive fixation, on the management of hemodynamically unstable pelvic bone fracture.

PURPOSE
Due to recent advances in internal fixation techniques, instrumentation and orthopedic implants there is an increasing number of humeral shaft fracture treated operatively. As a consequence, an increased number nonunion after operative fixation are being referred to our center. The aim of this study is to report the common error during osteosynthesis that may have led to nonunion and present a systematic analytical approach for the management of aseptic humeral shaft nonunion.
METHODS
In between January 2007 to December 2013, 20 patients with humeral shaft nonunion after operative procedure were treated according to our treatment algorithm. We could analysis x-rays of 12 patients from initial treatment to nonunion. In a subgroup of 12 patients the initial operative procedure were analyzed to determine the error that may have caused nonunion. The following questions were used to examine the cases: 1) Was the fracture biology preserved during the procedure? 2) Does the implant construct have enough stability to allow fracture healing? RESULTS: In 19 out of 20 patients have showed radiographic evidence of union on follow up. One patient has to undergo reoperation because of the technical error with bone graft placement but eventually healed. There were 2 cases wherein the treatment algorithm was not followed. All patients had problems with mechanical stability, and in 13 patients had biologic problems. In the analysis of the initial operative fixation, only one of 12 patients had biologic problems.
CONCLUSION
In our analysis, the common preventable error made during operative fixation of humeral shaft fracture is failure to provide adequate stability for bony union to occur. And with these cases we have demonstrated a systematic analytic management approach that may be used to prevent surgeons from reproducing the same fault and reduce the need for bone grafting.

PURPOSE
Specialized general trauma surgeons play an important role in the care of trauma patients. Hemoperitoneum is a severe, but representative, condition following a life-threatened trauma. The objective of this study was to compare the outcomes for polytrauma patients with hemoperitoneum between the periods during which a trauma surgeon was available and that unavailable.
METHODS
Thirty-one trauma patients with hemoperitoneum who were treated at Korea University Guro Hospital over a period of 4 years were included in this study, and their case records were analyzed retrospectively. The patients were divided into two groups, the 2011 and 2012 group and the 2013 and 2014 group corresponding, respectively, to the periods that a trauma surgeon was not and was working. Vital signs on admission, scores on the injury severity scale and, Glasgow coma scale, elapsed time to diagnostic, and therapeutic, and/or operative interventions were studied. The effects on intensive care unit and hospital lengths of stay, as well as mortality, were also studied.
RESULTS
The study population consisted of 16 and 15 patients in group 1 and 2, respectively. The patients in both groups had six unstable hemodynamic on admission. The time to the main procedure (intervention, operation etc.) was longer during the periods when a trauma surgeon was not working than it was during the period when working. This difference did not reached statistical significance. The mortality rates for the two groups were not statistically different either (18.75% vs 26.67%; p=0.928).
CONCLUSION
Having at least one specialized general trauma surgeon on duty may reduce the time to intervention and surgery for severe trauma patients with hemoperitoneum, but appears to have no effect on the mortality rates. In conclusion, having only one trauma surgeon on duty does not improve the quality of care for trauma patients.
