Osteoblastoma is rare, benign, bone-forming tumor that often occur in the spine. There are few reports of osteoblastomas resulting in pathologic fractures involving long bones. Authos report a unique case of a pathologic fracture due to an osteoblastoma of the humerus shaft. The tumor was treated successfully by curettage, intramedullary nailing and bone allograft.

견관절 전방 불안정성에서 관절와 및 상완골 결손이 동반된 경우 적절한 진단과 치료는 치료 결과에 직접적인 영향을 주므로 중요하다. 견관절 불안정성은 정적 및 동적 안정화 구조물의 손상으로 기인하며, 상완골 두감입 골절(Hill-Sachs 병변), 관절와 골절이나 전하방 관절와 가장자리의 소실 등 정상적인 관절의 해부학 구조물을 훼손시키는 골성 이상 소견이 동반되면 경우에 따라 견관절 불안정성에 영향을 끼칠 수 있다. 본 강좌에서는 견관절 전방 불안정성에서 동반된 관절와 및 상완골의 골 결손에 대하여 논하고자 한다.

상완골 근위부 골절의 치료를 위해서 실시하는 상완골 두 치환술은 고난도의 수술이다. 그러나 수술 수기에 만전을 기하고 골절을 위해서 특별하게 고안된 치환물을 사용하면 통증을 해소되는 것은 물론이며 대부분의 견관절 기능도 회복이 가능하다고 생각한다. 또한 보다 좋은 결과를 얻기 위해서는 치환물과 수술 수기 등에 대해서 지속적인 개선이 매우 중요하다고 생각한다.

Purpose: To evaluate the result and complication of treatment using Locking Compression Plate (LCP) for fracture of proximal humerus. Materials and Methods: Between 2004 and 2006, 21 patients with two-part and three-part fractures of the proximal humerus were treated by LCP fixation. Their average age was 54.9 years. Postoperative mean follow-up period was 22.9 months. The reduction was qualified and complication were assessed with final radiographs. The functional outcome was evaluated by Neer's rating system. Results: By Neer's functional evaluation, mean score of shoulder function was 86.3 and 18 case (86%) had excellent or satisfactory results. There was one case of nonunion but no infection or avascular necrosis of the humeral head. No correlation was found between the final result and the type of fracture, age, gender or quality of reduction. Conclusion: We obtained satisfactory result of LCP fixation for fracture of proximal humerus in this study. LCP fixation for proximal humerus fracture is a reliable method to obtain satisfactory reduction, rigid fixation and early exercise.

Purpose: Traumatic posterior dislocation of the shoulder in a child is extremely rare, and posterior dislocation of the shoulder concomitant with ipsilateral humeral surgical neck fracture has not been reported in a child previously in Korea. Materials and Methods: The authors treated a 10-year-old with posterior dislocation of left shoulder and an ipsilateral humeral surgical neck fracture, that occurred during Taekwondo practice, by open reduction of the shoulder and pin fixation under general anesthesia. Results: A normal range of motion with complete union and good remodeling was achieved without redislocation or avascular necrosis of humeral head at 1 year after surgery. Conclusion: The authors report a successfully treated case of traumatic posterior dislocation of the shoulder with an ipsilateral humeral surgical neck fracture in child.

Introduction: The treatment of proximal humeral fracture is traditionally determined by Neer's classification system. The severely displaced three-part or four-part fracture is an indication for primary hemiarthroplasty. The current authors report the clinical results of 10 patients who received hemiarthroplasty for proximal comminuted fractures. The minimum follow-up period was 12 months. Materials and Methods: The current authors studied 10 patients who, between July 1999 and March 2005, each received hemiarthroplasty for a proximal humeral fracture of one shoulder. According to Neer's classification system, 5 of the patients had three-part fractures, and 5 of the patients had 4-part fractures. The mean interval between trauma and hemiarthroplasty was 6.1 days. The mean age of the 6 female and 4 male patients was 67.4 years(range: 56 to 76). Shoulder function was evaluated using the Constant score, the Simple Shoulder Test, and the modified UCLA score. Results: The mean Constant score was 51.4(range: 34 to 60). The mean modified SST score was 7.8 out of 12 tasks. Excluding the one patient who had also sustained an axillary artery rupture and a brachial plexus injury after the initial trauma, the mean Constant score for the remaining 9 patients was 53.5(range: 44 to 60), and the mean SST score was 7.2 tasks. The modified UCLA score averages for pain, function, and active forward flexion and strength were, respectively, 8.2($6{\sim}10$), 6.6($2{\sim}8$), and 6.9($4{\sim}8$). The total UCLA score was an average of 21.7($12{\sim}26$). Patients' the modified UCLA ratings were as follows: Excellent: 3, Good: 6, and Poor: 1. The patient with the poor outcome was the one who had also sustained the neurovascular injury. Patient's subjective satisfaction rating were as follows: Excellent: 2, Good: 7, and Poor: 1. Conclusion: Based on short term follow-up results, this study indicates that hemiarthroplasty is the treatment of choice for proximal humeral fractures on which it would be difficult to perform open reduction and internal fixation. Hemiarthroplasty is a useful treatment modality to prevent shoulder stiffness and to allow daily living tasks in elderly patients. However, restoration of muscle power and range of joint motion were not recovered satisfactorily.

Purpose: To evaluate the clinical and radiographic results of the treatment of a proximal humerus fracture with a locking compression plate(LCP). Materials and Methods: This study reviewed the results of 24 cases of a proximal humerus fracture treated with a LCP from January 2005 to April 2007, after a follow up of more than 12 months. There were 8 males and 16 females with a mean age of 68.9(33-90) years. The clinical results were evaluated using the Neer's evaluation criteria, and the radiographic results were evaluated using the bone union time and Paavoleinen method. Results: The mean time for bone union was 11.9 weeks. Using the Neer's functional evaluation, 21 cases of the 24 patients (87%) showed excellent or satisfactory results. Twenty two cases (91%) showed good results according to the Paavoleinen method. The complications encountered were metal failure (1 patient), AVN of the humeral head (1 patient) and joint stiffness (1 patient). Conclusion: The LCP demonstrated good results in the treatment of a proximal humerus fracture and has relatively fewer complications than other internal fixators.
