Neurilemmomas, also known as schwannomas, are typically benign, well-encapsulated, slow-growing tumors originating from Schwann cells which encompass peripheral motor and sensory nerves. Neurilemmomas in parapharyngeal space (PPS) are very rare, but they can occasionally originate from the last four cranial nerves and autonomic nerves. In this article, we report the rare case of a 47-year-old male presenting solitary neck swelling and hoarseness. After computed tomography and magnetic resonance imaging, we performed complete surgical excision by a transcervical approach under general anesthesia. In the histologic examination, Neurilemmoma was diagnosed. The patient did not complain of any specific complications, showed good prognosis without recurrence or pain up to date.

목적: 70세 이상 노인에서 발생한 대퇴골 경부의 부전성 피로 골절(제1군)을 분석하여 외상성 대퇴골 경부 골절(제2군)과 비교하고자 하였다. 대상 및 방법: 2000년 1월부터 2006년 10월까지 70세 이상 노년에서 발생한 191예의 대퇴골 경부 골절 중 10예의 부전성 피로골절에 대하여 분석하였으며, 외상성 대퇴골 경부 골절과의 차이점을 골밀도, 고관절장축길이, 대퇴경간각 및 고관절장축길이 대 대퇴경나비의 비율을 이용하여 분석하였다. 결과: 대퇴골 경부 부전성 피로골절의 발생율은 5.2%이었다. 10예 중 단순 방사선 검사상 전위성 골절이 6예, 비전위 골절은 4예였다. 비전위골절은 모두 신장형(횡형)이었다. 경간각은 제1군에서 130.45도, 제2군에서 131.94도였으며, 고관절장축길이는 제1군에서 117.6 mm, 제2군에서 115.3 mm였고, 고관절장축길이와 대퇴경나비의 비율은 두 군에서 모두 0.30이었다. 골밀도는 제1군에서 T-점수가 -3.73, 대조군에서는 -3.4였다. 결론: 외상성 대퇴골 경부 골절군과의 비교에서 골밀도는 부전성 골절군에서 의미 있게 더 낮았으나 단순 방사선학적 계측상 경간각, 고관절장축길이 및 고관절장축길이와 대퇴경나비의 비율에서 유의한 차이는 없었다. Purpose: We wanted to compare the insufficiency stress fractures of the femoral neck (group I) with the traumatic femoral neck fractures (group II) in patients who were 70 years of age and older. Materials and Methods: Between January 2000 and October 2006, we evaluated 10 insufficiency stress fractures among 191 femoral neck fractures in patients who were 70 years of age and older. We compared these fractures with the traumatic femoral neck fractures by using the bone mineral density (BMD), neck-shaft angle, the hip axis length (HAL) and the ratio of the HAL to the femoral neck width. Results: The incidence of insufficiency stress fracture was 5.2%. There were 6 cases of displaced fractures and 4 cases of non-displaced fractures. All of non-displaced fractures revealed the tension (transverse) type. The mean neck-shaft angle was 130.45 degrees in group I and this was 131.94 degrees in group II. The mean HAL was 117.6 mm in group I and 115.3 mm in group II, and the ratio of the HAL to the femoral neck width was 0.30 in each group. The BMD (T-score) was -3.73 in group I and -3.4 in group II. Conclusion: The BMD of the insufficiency fracture group was significantly lower than that of the traumatic femoral neck fracture group. However, there were no significant differences in the neck-shaft angle, the HAL and the ratio of the HAL to femoral the neck width between the 2 groups.

Purpose: We compared the clinical features of the ankle fractures treated by operation between the elderly and the young, and reviewed the principles of treatment of the ankle fractures in the elderly. Materials and Methods: We reviewed 49 cases of the ankle fractures, which were treated by open reduction from August 1991 to July 2002. Patients aged more than 60 were designated as the elderly, and patients aged between 15 and 33 were designated as the young. The average follow-up period was 13.2 months. Using the Lauge-Hansen classification, We defined stage I or II fractures as low stage and stage III or IV fractures as high stage fractures. Results: There were 15 cases of high stage fractures (78.9%) in the elderly and 11 cases (36.7%) in the young. High stage fracture rate was significantly higher in the elderly (P=0.004). Hospital day, period between primary injury and operation, and union time were significantly longer in the elderly (P<0.001). However, there was no statistical difference in immobilization time between the two groups. The results of treatment were satisfactory clinically and radiologically by the Meyer's criteria in both groups. Conclusion: In the elderly, high stage fractures were more common and longer hospitalization and union time were needed than the young. However, the result of surgical treatment was satisfactory.
