The cement-free hip prosthesis coated with hydroxyapatite was developed to obtain primary firm fixation by an enhanced anatomic design and secondary biologic stable fixation by hydroxyapatite which is bioactive and has the same chemical and structural components with those of human bone tissue in total hip arthroplasty. Between January 1992 and June 1994, we used ABG cement free hip prosthesis (Anatomique Benoist Giraud, Howmedica Europe, Staines, England) in 28 hips (avascular necrosis of femoral head; 17, osteoarthritis; 6, posttraumatic arthritis; 3, rheumatoid arthritis; 2) of 25 patients in Pusan National University Hospital. Those cases had a minimum of two years and maximum of four years and five months (average three years and six months) of follow up, including analysis of the clinical and radiological data. The results were obtained as follows: 1. The average Modified Harris Hip Score increased from 51 points preoperatively to 96 points at last follow up. Almost all cases (97%) were excellent or good results in Modified Harris Hip Score. 2. In radiologic results, no migration of the cup, no change in the inclination of the cup, ar.d no oste-olysis around the cup and the stem were observed. Endosteal bone apposition around the cup was found in 54% of the cases and subcortical cancellous densification around the stem was found in 89%. This results indicate that we obtained direct and biologic firm fixation without fibrous tissue interposition between bone and metallic component by inducing on-growth of bone. 3. In the radiologic follow up according to the initial bone quality, it was demonstrated that the incidences of cortical hypertrophy, calcar resorption, and radiolucent line in type B and type C were higher than those in type A. The early clinical and radiological results of the cement-free hip prosthesis coated with hydroxyapatite are encouraging, although a longer follow up period is necessary.

The purpose of this study was to review the tendency of the Supreme Court's test for death from overwork (so called 'Karoshi'). Using inner-network of court, we analyzed judicial tests from 2000 to 2010, associated with claimed death from overwork and/or psychological stress. Judicial tests were classified according to the clarification of cause of death and preexisting diseases. Through analyzing relevantly the tests for death from overwork, the authors found that many tests have emphasized the necessity of forensic autopsy to elucidate the proper casual relationship between death and overexertion. This study also shows recent changes in judicial tests based on the latest medical knowledge. Therefore, it is suggested that social issue on forensic autopsy system need to recall Korean society to establish the clarification of the proper casual relationship associated with death from work as well as social justice.

PURPOSE: The Akin osteotomy which is a closing wedge osteotomy of the proximal phalanx widely used for the correction of hallux valgus has several methods of fixation. we tried to report the effects of the fixation using an absorbable suture material during the Akin osteotomy for the hallux valgus. MATERIALS AND METHODS: This study was based on 448 cases of 346 patients who were able for follow-up more than 12 months among the patients who had an Akin osteotomy together with the surgery of hallux valgus between March of 2006 and May of 2010. Absorbable suture material had been used in all cases. Radiologically displacement and union of osteotomy site were observed after the surgery, and clinically postoperative complication such as skin irritation, pain and satisfaction were investigated. RESULTS: Radiologically all cases had showed complete union and no case had the loss of an correction due to loss of fixation. Also, any case had no skin irritation due to a knot. Three cases had a medial cortical breakage due to a strong knot, and the initial one case among them had additionally fixed the osteotomy site for four weeks using K-wire, and the remaining two cases had fixed a suture on an articular surface without any fixation of an additional wire. If a medial cortical bone was lost by carrying out an ostectomy due to proximal protrusion of proximal phalanx, three cases could show union through the fixation of suture on an articular surface. CONCLUSION: This study considers that the fixation of the osteotomy site using an absorbable suture material in an Akin osteotomy was effective method and the advantage of this procedure was unnecessity of the material removal and no skin irritation.

PURPOSE: To evaluate the clinical results of operative treatment of the intra-articular calcaneal fracture with injectable calcium sulfate (MIIG(TM)). MATERIALS AND METHODS: Between March 2004 and October 2006, a total 19 intra-articular calcaneal fracture (16 patients) with a large bony defect that underwent operative treatment with plate fixation and injectable calcium sulfate (MIIG(TM)) with minimum follow-up of one year following. The mean age at time of surgery was 44.7 years (23 to 54). All of the cases were type 2 and 3 on the basis of Sanders classification. The lateral L shaped approach was used in all cases. Full weight bearing on the affected extremity was regained at an average 10 weeks postoperatively. RESULTS: The mean B?hler angle was improved from 2 degrees (-18.5~12.5 degrees) preoperatively to 23.8 degrees (12~37.5 degrees) and the angle at last follow-up was 22.5 degrees (11.5~37.5 degrees), showing about 0.3 degree decline compared to postoperative B?hler angle. Only two case of whitish leakage of graft material but other complication were none. CONCLUSION: MIIG(TM) augumentation of displaced intra-articular calcaneal fracture with large bone defect seems to bo useful method for initial stabilized and plate fixation.

PURPOSE: When medial protrusion in the base of proximal phalanx is severe from removing metatarsal bunion during the hallux valgus surgery, it could lead to skin irritation and medial pain after the surgery. The purpose of this paper was to report our clinical and radiographic results with transarticular fixation of Akin osteotomy for the treatment of patients with hallux valgus after resection of the medial protrusion of base of the proximal phalanx. MATERIALS AND METHODS: Our study is subject to 34 cases of 30 patients who went through proximal phalanx medial corticectomy among patients undergone both hallux valgus surgery and Akin osteotomy at our institution from March 2006 to March 2012. In all cases, we used absorbable suture material through the articular surface for Akin osteotomy after resection of the medial protrusion in proximal phalanx. Radiographs were reviewed to assess the union and displacement of osteotomy site at the time of postoperative 6 months. The clinical results were assessed by using AOFAS score and complication such as skin irritation and pain. RESULTS: AOFAS score was improved from average 44 points(36-58), before operation and average 87 points(74-96), 12 months after operation. In two cases, partial union was suspected in radiological perspective, however, complete union on the osteotomy site was observed in all cases, 12 months after the operation. No patients was dissatisfied with pain, joint discomfort, skin irritation and inflammation from the knot. CONCLUSION: When medial protrusion in the base of proximal phalanx is severe from removing metatarsal bunion during the hallux valgus surgery, We have good results by transarticular fixation of Akin osteotomy using absorbable suture material.

PURPOSE: Painful plantar callosities under the second, third or fourth metatarsal head have been controverted about its treatment mordalities. We performed the vertical chevron osteotomy in patients with painful callosities on the second and third metatarsal head, and evaluated the outcome clinically. MATERIALS AND METHODS: Fourteen cases from 10 patients who had plantar keratosis were operated by vertical chevron osteotomy from March 2005 to October 2008. We used K-wire fixation for all cases. We evaluated the clinical results by the patients' satisfaction and disappearance of plantar lesion. RESULTS: The plantar keratosis was completely disappeared in 8 cases and partially in 5 cases. In 2 cases, patients expresses their pain caused by constant metatarsalgia that was suspected to be dorsal incisional pain and joint capsulitis. Transmetatarsalgia was not appeared. CONCLUSION: We consider vertical chevron osteotomy as a good surgical method for treatment of plantar keratosis.
