ABSTRACT
PURPOSE: To investigate the surgical outcomes of orthogonal locking compression plate fixation for distal humeral intraarticular fractures. MATERIALS AND METHODS: This study included 18 patients presenting a distal humeral intraarticular fracture who were treated with orthogonal locking compression plate fixation. According to the AO/OTA classification, there were eight C2 and ten C3 fractures. We evaluated radiologic outcomes, clinical results with range of motion, operation-related complications, and functional score by Mayo elbow performance score (MEPS). RESULTS: The a verage u nion t ime was 3.5 months, and there was no c ase of r eduction l oss of a rticular f racture at t he last follow-up. Additional surgical procedures were needed in the three cases of C3 fractures. There was one case of heterotrophic ossification and one case of K-wire irritation. The average range of motion of elbow joint was 7° to 122°, and functional results were graded as 14 excellent, three good, and one fair by MEPS. CONCLUSION: Anatomical reduction and internal fixation with orthogonal locking compression plate could provide satisfactory surgical outcomes for the treatment of distal humeral intraarticular fracture.

PURPOSE: Splenic injury management has shifted to non-surgical treatment to preserve the spleen because of the postoperative risks of overwhelming post-splenectomy infection. In this study, we analyzed risk factors of therapeutic options for splenic injury, using medical records of Chonnam National University Hospital. METHODS: We reviewed the medical records of 110 consecutive patients with traumatic splenic injuries admitted from January 2009 to December 2013. Demographic characteristics and therapeutic options such as conservative treatment, angiographic embolization and emergency operation and clinical parameters were analyzed in this study. RESULTS: Thirty-four patients were treated surgically and seventy-six were managed with nonsurgical treatment. Multivariate logistic regression identified age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.009~1.072; p=0.01), hematocrit (OR, 0.878; 95% CI, 0.806~0.957; p=0.003), contrast extravasation (OR, 7.644; 95% CI, 2.248~25.986; p=0.001), spleen grade (OR, 2.08; 95% CI, 1.128~ 3.836; p=0.019) as significant risk factors of emergent splenectomy. CONCLUSION: Age, hematocrit, contrast extravasation, spleen grade were significant risk factors for emergent splenectomy.

Hemorrhage is a major cause of death in trauma patients. The medical definition of hemorrhagic shock is tissue hypoperfusion resulting from a reduction of blood volume. Decreased blood pressure resulting from acute blood loss induces cardiac stimulation, systemic vasoconstriction, and volume redistribution. These effects are due to the baroreceptor reflex, the humoral compensatory mechanisms including the renin angiotensin system, and the release of catecholamine and vasopressin. Hemorrhagic shock causes acidosis, hypothermia, and coagulopathy, known as ‘the lethal triad.’ Tissue hypoxia induces metabolic acidosis by producing lactic acid. The three components of the lethal triad amplify each other and form a vicious cycle, eventually causing the death of the patient. To reduce the risk of mortality in severely bleeding patients, we need to understand the pathophysiology of hemorrhagic shock and the related complications.

PURPOSE: Several techniques have been introduced for correction of pes cavo-varus deformity. We retrospectively reviewed and compared the data of patients who underwent 1st metatarsal osteotomy alone, Dwyer's osteotomy alone, and 1st metatarsal osteotomy combined with Dwyer's osteotomy to determine the effect on radiographic parameters. MATERIALS AND METHODS: Data on 28 cases in 27 consecutive patients recruited from 2006 to 2014 who underwent 1st metatarsal osteotomy alone (group F), Dwyer's osteotomy alone (group H), or 1st metatarsal osteotomy followed by Dwyer's osteotomy (group HF) with a minimum 1-year follow-up were reviewed retrospectively. RESULTS: Calcaneal pitch angle on the standing foot lateral radiographs was significantly decreased after the operation in groups H and HF whereas Meary angle was decreased in groups F and HF. Hindfoot alignment angle and ratio on the hindfoot alignment view were improved in groups H and HF. Maximal medial cuneiform height reduction was observed in group HF. 1st ray was significantly shortened in groups F and HF. CONCLUSION: Combined forefoot and hindfoot operation took the largest correction power of all radiologic parameters.
