Treatment of chronic localized osteomyelitis is the same as the other osteomyelitis, that is, curettage and debridement of all dead tissue which is called saucerization. After saucerization there leaves empty cavity and autogenous bone graft has been used for filling the cavity in lower extremity hecause of weight bearing and avoiding fracture. We treated seven cases of chronic localized osteomyelitis with one-staged saucerization and cancellous chip allograft and retrospective analysis was done. All healed without complication and no recurrence was ohserved. Most orthopaedic surgeons are not willing to use allograft on the site of osteomyelitis because of the fear of recurrence. But. we think that as far as complete removal of infected and dead tissue, allograft could he a good solution in terms of rapid remodelling and early weight hearing. Another advantages of allograft are to get a large amount of bone and no damage of iliac apophysis. In summary, one-staged saucerization and cancellous chip allograft would he very useful treatment for chronic localized osteomyelitis.

We evaluated the effectiveness of photoastigmatic refractive Keratectomy(PARK) by excimer laser on patients with compound myopic astigmatism. Spherocylindrical PARK was performed on 181 myopic eyes with astigmatism(mean spherical equivalent : -6.61 D, range : -1.88~-14.5 D) using the visx excimer laser. The eyes were divided into three groups according to the amount of desired astigmatic correction : Group 1(-0.5~-1.0 D), Group 2(-1.25~3.0 D), and Group 3(-3.25~-5.5 D). Patients were followed up for 6 months. Uncorrected visual acuity at postoperative 6 month, was 0.80+/-0.27 in Group 1, 0.79+/-0.19 and 0.71+/-0.21bin Group 2 and 3 respectively. The mean spherical equivalent refraction was -0.24 D 6 months after PARK. Mean astigmatism was reduced from preoperative -0.85+/-0.51 D to postoperative -0.34+/-0.38 D in Group 1, from -2.08+/-0.65 D to -0.43+/-0.64 D and from -4.42+/-0.63 D to -1.23+/-1.25 D in Group 2 and 3 respectively. We also analyzed the angle of error, magnitude of error, index of success, and coefficient of afjustment by vector analysis. No significant complications were observed during the follow-up period. These results show that PARK by excimer laser was effective in correction of astigmatism. The effect of astigmatic correction in Group 2 and 3 were better than that of Group 1. Group 1 showed overcorrected tendency and Group 2 and 3 showed undercorrected tendency.

Vertical and marginal fractures of the patella are uncommon injuries compared with other types of patellar fracture. It's possible that they are more common than supposed, but often remain undiagnosed as acute injuries. Vertical and marginal fractures often results in less acute disability than stellate or transverse fracture and the routine radiographs are often unhelpful. Failure to diagnose acute vertical and marginal fractures of the patella, especially when the fragments are displaced, may result in prolonged disability of the knee and possible development of degenarative changes in the patello-femoral joint later. Twelve patients of the vertical and the marginal patellar fractures treated at St. Mary's Hospital from Feb. 1982 to Dec. 1987 were analyzed in clinical and radiological aspect. The results obtained from this study were as followings. 1. Vertical and marginal fractures had 15.4% of injury rate in all patellar fractures. 2. The fracture and its displacement were always present on the tangential view of the patella. 3. The mechanism of the fracture was s direct blow to the patella in which the affected knee was flexed. 4. The location of the fracture line was related to the degree of the flexed knee at the time of fracture. 5. Large separated fragments of the patella should be accurately reduced with rigid fixation in the rationale of the intraarticular fracture.

Penetrating autokeratoplasty for optical has seldom been reported in recent literature. The patien presented here is a male, aged 31, farmer, who had a dense extensive corneal scar in his right eye. Keratoplasty, 6.5mm in disc diameter. 8 edge-to-edge direct sutures, postoperative beta-radiation, had been performed eventlessly on July 15. 1964 and postoperative reaction was minimum. The visual acuity improved from counting finger 30cm to 0.1 of Landolt's broken ring chart after 4 months of follow up observation. Minimum postoperative complication makes authors postulate autoplasty is relatively safe procedure.

It was in 1906 that Apert first described in detail the detail the group of deformities which now bears his name. He proposed the name Acrocephalosyndactly for this syndrome and presented a case he had personally examined in 1896 as well as a review of similar cases reported prior to his publication. since that time Acrocephalosyndactyly and Apert's syndrome have become synonymous. More than 200 cases have been reported in the world literature. The purpose of this article is to report an additional case along with review of previous literatures.

A cause for spontaneous paralysis of the posterior interosseous nerve has been sought for many years. In recent times an increasing number of reports on this subject has appeared. This paper describes a probable anatomical factor, the arcade of Frohse, in non-traumatic progressive paralysis of the posterior interosseous nerve. Though this arcade, described by Frohse (Frohse and Fraenkel 1908), the posterior interosseous nerve passes to enter the plane between the two heads of the supinator muscle. In this case, the arcade of Frohse may well play in causing progressive paralysis of the posterior interosseous nerve, with old anterior dislocation of the radial head. Paralysis of the muscles supplied by this nerve with no evidence of recovery should be treated by exploration and splitting of the arcade of Frohse.

The osteoplasties of maxilla and mandible as the craniomaxillofacial surgery is popular and markedly developed in technically. In traditional osteoplasty, we have been use the mechanical saw, burr, cutting bar which is big sized instrument to transmit the energies to the saw or burr tips. So it is technically difficult to use such big instrument in narrow operative field Recently, the development of laser technology makes wider influence in the medical field. So, the laser is applying to high energy-using osteotomy in addition to hemangioma, tatoo, laserbrasion, hypertrophic scar and endoscopic surgery. The objective of the present study is to evaluate the extent of damage of bone and subsequent healing between the conventional mechnical saw osteotomies and the ND-YAG laser used osteotomies on the rabbit mandible angles by the histologic examination. Fifteen New Zealand white rabbits were used for the study. After exposure of rabbit's mandibular angle, one side of mandible angles were osteomized used by Nd-YAG laser and the other by the saw randomly. We compared the extent of damage and healing of laser and saw osteotomies at immediate, 2 week, 4 week, 3 months, 6 months postoperatively. The result revealed that, in two weeks after operation, the one of damaged bone was looks wider in laser osteotomies sites than by conventional mechanical saw osteotomies sites, but there is not remarkable differences between the laser and saw used group after 4 weeks, and we believe that it is possibility to use alser in craniomaxillofacial field saftly in near future.
