Enchondromas generally occur in the hand and uncommonly in the long bones. Because enchondromas are usually asymptomatic, most are discovered during diagnostic radiology for another disease. Here, we describe a case of enchondroma in the right humerus in a 79-year-old female patient with concomitant rotator cuff tear arthropathy. The patient was initially hospitalized for prolonged pain and pseudoparalysis of the right shoulder. The condition, which was histologically confirmed as an enchondroma in the proximal humerus, was treated with curettage and reverse total shoulder arthroplasty. In this case report, we present a rare case of an enchondroma with combined rotator cuff tear arthropathy.

Thirteen Polio patients with leg length inequality were undergone Ilizarov lengthening procedures and have been followed along for an average two years(range, 1-3.8 years) after removal of the fixator. The age of patients(M:F=7:6) ranged from 18.0 to 32.2 years(average 26.4 years). The difference of true leg length averaged 2.1cm with the tibia being 3.3cm the femur, 1.2cm. The corticotomy was done at the proximal tibia and distal fibula in all case. The fixation period of the Ilizarov apparatus averaged 9.3 months. The length gain averaged 3.0cm for an average 3.8cm inequality. The healing index averaged 3.1mon/cm. Two out of thirteen patients complained of pain in the operated leg. The limping gait was improved in all patients except one. According to Paley's classification, there were ten cases of problems, one obstacle and four true complications. The problems were pin site infection controled with local antibiotics injection. There was one case of obstacle; tibial valgus deformity developed during lengthening. True complications included peroneal nerve injury, aggravation of preexsiting equinovalgus and claw toe deformities, aggravation of preexsiting valgus deformity of ankle and tibial valgus deformity. The complications execpt in one case of peroneal nerve palsy were solved out by the secondary procedures. In summery, the bone healing by distraction osteogenesis with the Ilizarov technique was relatively delayed in polio patients and it seems necessary to modify the technique to shorten the prolonged external fixation period.

Proximal femoral nail anti-rotation (PFNA) with a lag screw that is shaped like a spiral blade shape is an orthopedic implant to fix trochanteric fractures of the proximal femur. In addition the reason of the biomechanical advantages, PFNA widely been used recently. We report an 83-year-old man with excessive sliding of the helical blade and a femoral neck fracture after AO/OTA type A2 intertrochanteric fracture, which was fixed with a PFNA.

Bovine growth hormone (bGH) gene was expressed in an insect spodoptera frugiperda cell line using a Baculovirus, Hyphantria cunea nuclear polyhedrosis virus (HcNPV). The bGH gene in pbGH plasmid was sequenced and amplified by PCR technique with two primers containing NcoI sites. The bGH gene consisted of 654 bp (217 amino acid residues), the 5'-untranslated region of the cloned bGH cDNA contains 56 bp, and the 3'-untranslated region contains 145 bp and two pallindromic regions. The amplified bGH gene DNA fragment (654 bp) was inserted into the NcoI site of the pHcEVII vector, which was named pHcbGH. The pHcbGH transfer vector DNA and the wild type HcNPV DNA were cotransfected into s. frugiperda cells to construct a recombinant virus. Eight recombinant viruses were selected and named HcbGH. One clone, HcbGH-4-1 showed largest plaque size, therefore the recombinant virus was further studied. The multiplication patters of the recombinant HcbGH-4-1 was similar to that of the wild type HcNPV. The bGH gene DNA in the HcbGH-4-1 recombinant was confirmed by Southern lot hybridization. The amount of the bGH (217 amino acid residues, 21 kDa) produced in S. frugiperda cells infected with the HcbGH-4-1 recombinant was approximately 5.5 ng per ml (106 cells) by radioimmunoassay.

Recently, the use of intramedullary nailing for proximal femoral fractures has increased. Breakage of the nail usually occurs at the un-united fracture site, and it is a rare complication of intramedullary nailing of the femur. However, removal of the distal fragment of a broken nail is a challenging problem. Herein, the authors describe the methods used for removal of relatively fixed or strongly fixed broken intramedullary nails in two different cases.

OBJECTIVES: This Study was designed to investigate the pattern of AUI(Alcohol Use Inventory) and MAST(Michigan Alcohol Screening Test) according to the awareness of drinking problem and receptiveness to treatment, and to know whether the type(type1 and type 2 according to Barbor's typology) has effects on the RECPAWAR(acknowledgement and awareness of use problem and receptive to treatment of these problem) score. METHODS: Subjects were 134 alcoholic patients from Alcoholic treatment ward. They were requested to fill up the questionnaires of Korean version of AUI and MAST(MAST for patient and MAST for caretaker). At first, based on the RECPAWAR, they divided into high RECPAWAR group(above 30 percentile) and low RECPAWAR group(below 30 percentile). According to typology, they divided into type 1 and type 2. The data was analyzed by T-test, Correlation, and Regression Analysis. RESULTS: 1) Significant negative correlation was observed between RECPAWAR score and MAST difference score(patient's MAST-caretaker's MAST). 2) High RECPAWAR group had significantly higher scores in the most scales than low RECP-AWAR group, except ENHANCED scale in AUI. 3) There was not significant difference on RECPAWAR score between type 1 and type 2. CONCLUSION: Except ENHANCED scale, the high RECPAWAR group had higher score in the second level scale. As compared with the low RECPAWAR group, the high RECPAWAR group responds more negative in drinking, and is more anxious about their drinking problems. So, they seem to have the objective view about their drinking problems. However the type was not related to receptive and awareness of drinking problem.

Although antibiotics have greatly improved the results of treatment of hematogenous osteomyelitis, hematogenous osteomyelitis in children is still complex and difficult disease by which severe deformity and disability may result. A retrospective clinical study of 44 cases of hematogenous osteomyelitis in children was done at Department of Orthopaedic Surgery, Busan National University Hospital from January 1980 to February 1985. The results were as follows: 1. The ratio between males and females was 2.1: 1, and the prevalent age gmup was from 11 to 15 years. 2. The common sites of involvement were femur and tibia in orders. 3. At initial surgical treatment, fenestration in acute stage and saucerization in chronic stage were commonly performed. And at surgical wound management, primary closure with closed continuous irrigation was most frequently performed. 4. Children with acute clinical presentations tended to have more unsatisfactory results, probably because of delay of diagnosis and treatment, simple soft tissue drainage at initial surgical treatment, secondary closure at surgical wound management and inadequate parenteral antibiotic therapy.

With the increase of motor accident, the rate of popliteal artery injury is increased, As the injuries are critical, early diagnosis and prompt treatment can save the limb. 27 cases of popliteal artery injury patients were reviewed and the result was as follows ; l. Amputation rate was 11%, as 3 out of 27 cases failed. There was no correlation between ischemic time and the rate of amputation. 2. Complete resection of all injured portion of vessel and reconstruction of patency through interposed saphenous vein graft was often indicated to avoid tension at the anastomosis site. 3. The rate of fasciotomy was positively correlated with the ischemic time. 4. Medial approach is preferred to posterior approach, since it makes proximal extension of exploration possible, and decrease the incidence of joint contracture. 5. Complications noted are wound infection, systemic sepsis and venous stasis, but they could be treated with proper management. However, nerve deficit due to associated nerve injuries was resist to treatment.

We report our series of the Ilizarov surgery for lengthening and deformity correction in upper extremity at the Severance Hospital and the Yong-Dong Severance Hospital between February 1992 and October 1994. We performed the Ilizarov surgery in 12 limb segments, there were 3 humerus, 5 radius, 3 ulna and 1 metacarpal bone. The etiologies of the limb length discrepancies were 7 posttraumatic physeal injuires, 2 congenital deformities, 1 posttraumatic bone loss, 1 posttraumatic amputation and 1 postinfectious physeal injury. The goals of treatment were bone lengthening alone in 8 cases, bone lengthening and deformity correction including angular correction in 4 cases. The bone was lengthened between 1.0 cm and 9.2 cm (mean 3.7 cm) representing a 8.1% to 63.0% (mean 24.5%) increase in length. The healing index varies from 1.0 mos/cm to 10.5 mos/cm (mean 3.4 mos/cm) except three cases which need additional fixation with plate and screws add to wedge osteotomy. By radiologic appearance of the distraction callus, the straight type were 6 cases, the attenuated type were 4 cases and the pillar type were 2 cases. The healing indices of each type were 1/5 mos/cm, 7.7 mos/cm and 12.4 mos/cm, respectively. In conclusion, lengthening and deformity correction of the upper extremity can be successfully achieved by gradual mechanical distraction using the Ilizarov method. In case of pillar type, healing index was high and therefore control of the rate and the rhythm should be tried. If this control is of no use, early interventional procedure would be beneficial. The healing index of the straight type was much lower than that of the attenuated or the pillar type.
