The authors report two cases of successful reconstruction in infected nonunion of the femur involving marked shortening by compression and gradual distraction at the nonunion site using Ilizarov external fixator. At first, infection was controlled by radical excision & the administration of systemic antibiotics for four weeks and we also started compression at the nonunion site 3 days after operation. Autogenous iliac bone graft was added to strengthen the site of new bone formation lastly. In this report, the role of the compression seems to provide a good environment for distraction osteogenesis by focal necrosis and triggering inflammation. Compression and gradual distraction may be one of the treatment mordalities for nonunion of a long bone with massive bone loss or shortening, even infected.

The tibial pilon fracture has been described as difficult fracture to manage. We have reviewed 23 cases of tibial pilon fractures from Mar. 1987 to Feb. 1993 at our hospital. 1. The fractures were classified into five types according to the system of Ovadia and Beals and the methods of treatment were divided into two groups; 9 cases were treated with Ilizarov device(Group I). 6 cases out of Group I were type 3, 4 and 5. Other methods were performed in 14 cases(Group II). 8 cases out of Group II were type 3, 4, and 5. 2. In type 3, 4 and 5 fractures, there were 86 per cent good and fair radiographic results in Group I and 63 per cent good and fair results in Group II. 3. Satisfactory results were obtained by the treatment of Ilizarov method especially in type 3, 4 and 5 fractures. The advantages of Ilizarov device were its primary reduction with ligamentotaxis, easy open reduction due to proximal and distal stabilization, minimal soft tissue injury and minimal internal fixation.

Thirteen cases of lengthening of short tubular bone by gradual axial distraction using an unilateral external fixator(Orthofix M-100, Orthofix CP0089) are reported. This study aims to prove effective- ness of gradual distraction for lengthening of short tubular bone and usefulness of the newly designed external fixator. Nine patients had brachymetatarsia and four brachymetacarpia. The etiology was consisted of post-traumatic physeal injury in two and congenital in eleven cases. The average amount of lengthening was 14.5mm(37.0%) in metacarpal bone, and 17.3mm(37.5%) in metatarsal. Complications were angular deformity in 3, pin loosening in 2 cases, and premature consolidation, nonunion and pin site infection in one case, respectively. Cosmetical and functional satisfactory results were obtained in all cases. We believe that callotasis is effective for short tubular bone lengthening. Also we confirmed the newly designed external fixa- tor(Orthofix CP0089) useful.

Objective: The aim of this study was to develop a Korean version of the Thinking About Life Experiences (TALE-K) scale and to analyze the characteristics of autobiographical memory function (AMF) in community-dwelling older adults. Methods: To develop TALE-K, a translation and back-translation procedure followed by an understanding test was performed. Then, a survey was conducted to examine the associations of AMF with psychosocial variables using TALE-K, Index of Well-Being (IWB), Meaning in Life Scale for older adults, Revised UCLA Loneliness Scale, Medical Outcomes Study Social Support Survey, and Brief Resilience Scale. Results: Data from 75 community-dwelling older adults were used for the final analysis. The average scores of all three sub-scales of TALE-K were below 3 points (less frequent than occasionally). The correlation results showed that TALE-K total score was significantly associated with IWB and the Meaning in life scale for older adults. The multiple linear regression results present-ed that higher AMF was significantly associated with higher IWB, along with having siblings, higher meaning in life and resilience,and lower loneliness. Conclusion Including a validation study of TALE-K, studies for understanding the characteristics of AMF in older adults using TALE-K are needed.

This is a case report of correction of malunioned maxilla after traffic accident by Le Fort I osteotomy and posterior segmental osteotomy. By this procedure, authors obtained the following results. 1. The malunioned maxilla after traffic accident which had anterior crossbite, posterior open bite and scissor's bite were corrected by Le Fort 1 osteotomy and posterior segmental osteotomy. 2. No postoperative infection and specific complication were seen in this case. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. And then, the patient could open his mouth in normal range after a week of intermaxillary fixation removal. 4. For rigid fixation and reducing relapse, the osteotomized maxilla was fixed with miniplates.

Cauda equina syndrome(CES) and disc rupture have been implicated as a potential complication of spinal manipulation. A review of the literature from 1911 to 1996 received 61 reported cases of cauda equina syndrome or disc rupture in patients undergoing manipulation. This article presents four new cases, where a temporal association was found between the onset of cauda equina symptoms or disc rupture and lumbar manipulation. The type of manipulation administered and the relationship between the treatment and symptoms is reviewed. Our patients symptoms suggest that acute herniation was caused, or at least precipitated by spinal manipulation. In each of these cases the chiropractitioner failed to comprehend the nature of the problem and take appropriate action. As a consequence, the patient went untreated for several days. Many chiropractic therapists assumed the incidence of CES caused by manipulation to be approximately one in many millions of treatments. However, we assumed that CES or disc rupture is far more common than the literature would reflect. It is therefore essential that persons practicing or prescribing manipulation would be aware of these complications.

This is a report of 2-cases of mandibular prognathism corrected by Intraoral oblique splitting osteotomy of mandibular rami. The Intraoral oblique splitting osteotomy is a modification of sagittal split osteotomy of ramus and it is documented by Yoshida, on 1985. By this method, authors obtained the following results. 1. The patients' esthetic, psychological and functional problems were dissolved by setback of mandibular prognathism. 2. The postoperative infection splitted bone segments fracture, paresthesia of the face and T.M.J. dysfunction were not appeared. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. The patients could open their mouths in normal range after a week of intermaxillary fixation removal. 4. The soft tissue changes of lower lip and chin were about 1:1 to the hard tissue changes. 5. During intermaxillary fixation period and postoperative orthodontic treatment, slight relapse was observed. Now, the patients are under postoperative orthodontic treatment.

PURPOSE: To investigate the etiologic factors related to refractures of the upper extremity in children MATERIALS AND METHODS: 18 refractures of the upper extremity were divided into three groups according to the location of initial fractures: Supracondyle fractures of the humerus, lateral condyle fracture of the humerus, and the forearm bone fractures. They were analyzed in terms of the type of refractures (early refracture occurring at the immature callus and late refracture occurring at the remodeled bone), fracture patterns, and the existence of underlying deformity. RESULTS: Nine supracondyle fractures had refractures at the supracondyle (2 cases) and the lateral condyle (7 cases), in which underlying cubitus varus were present in 6 cases. Three lateral condyle fractures had refractures at the supracondyle (1 case) and the lateral condyle (2 cases), in which one case had underlying cubitus varus. All but one case in the group of humerus fractures were late refractures and treated operatively except one. Of 6 refractures of forearm, 5 were early refractures and occurred within 9 weeks at the original site: 4 at the diaphysis of both bones of forearm and 1 at the diaphysis of ulna. All cases in the group of forearm fractures had volar angulation before the refracture, and treated conservatively except one CONCLUSION: In the humerus, underlying cubitus varus was the most important predisposing factor to refractures and the lateral condyle fractures were common. In the forearm, volar angulation of the diaphysis were related to refractures, and complete and circular consolidation of the primary fracture of forearm was thought to be important to prevent refracture.

Two patients, sought treatment for chief complaints of protruding frontal tooth and desired treatment to reduce the prominence of lips, were diagnosed as bimaxillary protrusion via clinical and cephalometric analysis. The authors corrected them by combined surgical and orthodontic treatment. As pre-surgical survey, paper and cast surgery were performed and wafer and resin sprint were constructed. We performed anterior maxillary and mandibular osteotomies in first premolar site to retract the maxillary and mandibular dentoalveolar segment in order to; 1) Decrease prominence of upper and lower lips. 2) Create proper lower incisor intrusion. By use of intramaxillary fixation, prompt oral intake was possible. We made good result of esthetic improvement and there was no evidence of relapse and any complication.
