The intramedullary nailing for humeral shaft fractures has become popular fixation method. It affords less invasive procedure, good stability and early rehabilitation. However many complications were reported such as nonunion, pain and motion limitation of shoulder. We managed 33 patients using interlocking intramedullary nail for the humeral shaft fractures, and nonunion occurred in 9 patients. We reviewed these 9 cases and analyzed the relationship between the nonunions and the fracture sites as well as fracture types. The results were as follows; 1. Nonunion occurred in 9 patients of 25 patients treated closed reduction, but did not occur in 8 patients treated open reduction. 2. The union was obtained in all 6 patients with proximal one third fracture. But nonunion occurred in 6 patients of 19 patients with middle one third fracture and in 3 patients of 8 patients with distal one third fracture. 3. Nonunion after interlocking nails for humeral shaft fractures did not occur in all 6 spiral fracture patients. Nonunion occurred in 5 patients of 8 comminuted fracture patients, in 3 patients of 6 transverse fracture patients and in 1 patient of 3 oblique fracture patients with below the middle one third of humerus. Our study showed that the high rate of nonunion occurred in the comminuted, transverse and oblique fracture below the middle one third of humerus. On the basis of these findings, we recommend that closer attention should be paid when choose the fixation method in these types of the humeral shaft fractures.

OBJECTIVE: The purpose of this study was to describe the clinical presentation and histopathologic findings that help in decisions about management of ovarian mass in childhood and adolescence. METHODS:We retrospectively analyzed the data on 307 patients with surgically treated ovarian mass under 20 years of age at the Cheil General Hospital, between January 1995 and December 2005. RESULTS: Of the 307 cases, 40 cases (13%) were ovarian malignancy. The incidence of malignant ovarian tumor increased to 16.9% in 237 neoplastic tumors. Epithelial, germ cell, and sex-cord stromal malignancies accounted for 57.5%, 30% and 12.5%, respectively, of the 40 ovarian malignancies. The stage of the 35 cases (87.5%) with the ovarian malignancy was the FIGO stage I. The incidence of ovarian malignancies increased with larger size, higher CA125 level. Solid ovarian masses on ultrasound were more likely ovarian malignancy. But age and menarchal status was not correlated with ovarian malignancy. Mature cystic teratoma seen in 132 patients (55.7%), was the most common neoplasm of ovary in this age group, and the incidence of bilaterality was 12.1%. On follow up, 4.9% (13/267) of previously diagnosed benign ovarian tumor were reoperated due to recurred or newly developed ovarian tumor. After cystectomy, the recurrence rate of ipsilateral ovarian tumor was 2.8% (4/142). CONCLUSION: If there is no evidence of malignancy, conservative surgical treatment should be employed to preserve future endocrine function and fertility in this age group.
