The purpose of this study is to evaluate the superficial bony healing after guided bony regeneration using a various bone grafts. Four types of bone grafts were performed by one oral and maxillofacial surgeon to restore the defects around endosseous implants. Group I included the allografts using $Regenaform^{(R)}$. Group 2 included the autograft. Group 3 included the combined grafts using with autogenous symphysis bone and xenograft($BioOss^{(R)}$). Group 4 included the xenograft($BioOss^{(R)}$). After some heling period, superficial bone biopsy was performed with the surgical blade(#15) during the second surgery. Histologic and histomorphmetric examination were carried out by one pathologist. There was the most new bone formation in the group 3, next group 2. However, there were no statistically significant differences. All group except for group 4 showed favorable bone formation and remodeling.

A 23.5 kg179, 8 months olds non-spaycd female Rottweiler dog was submitted to the veterinary teaching animal hospitals Chonbuk: national university, for chronic bitten trauma on right foreleg with pain, lameness, and pronation. The patient fought with a neighboring dog about five months ago and had mild anorexia, depression, bolt normal walking at that time. CBC and blood chemical examination were in normal range. Physical examination resulted in the right foreleg with edema and interval rotation of carpal joint. Radiograph of the right carpus showed varus and subluxation. We finally diagnosed the patient as the growth deformity of distal radius and ulna caused by medial premature closure of distal radial physis. Osteotomy was performed fur reforming of the varus of the distal radius and ulna with 6-hole straight plate and six 3.5 mm screws. Panarthrodcsis of carpus was preformed for correcting subluxation using 6-hole T-shaped plate and four 3.5 mm screws with cortical onlay autograft and strengthened by two 3.5 mm screws and tension wire band in lateral aspect of the carpus. Follow-up radiographs after 16 weeds of the surgery showed complete coaptation of osteotomy sire of the radius and uIna. After 6 months of the procedurc, talc plate, screws and the wire were removed except 7-shaped plate and four screws fur arthrodesis. The patient was seen in normal forelimb and could walk and run without lameness after 7 months of the procedure.

Despite of technical advances in surgery & other therapeutic modalities five-year survival rates in patients with carcinoma of hypopharynx have remained low. Many techniques have been used to create a structure capable of allowing the passage of food and fluids in an attempt to maintain the anatomy and physiology of the upper digestive system. The development of microsurgical techniques and the concept of mucocutaneous unit has brought about important changes in the reconstruction of cervical esophagus following tumor resection. The one-stage procedure using microvascular anastomosis of free jejunal graft provides physiologic reconstruction of cervical esophagus and has a low morbidity rate as well as a short recuperation time. With free jejunal graft, there is marked improvement in the quality of life and numerous advantages over the previous methods of reconstruction. Reconstruction of esophageal defect after resection of carcinomas of the hypopharynx, and cervical esophagus has traditionally been carried out with deltopectoral, or musculocutaneous skin-lined flaps. A second approach is to reconstruct the defect with the colon or stomach. A more ideal mettled is to repair these defects with mucosa-lined flaps. The authors experienced 35 cases of reconstruction of cervical esophagus after resection of carcinoma of the hypopharynx with free jejunal autograft and one case of secondary repair with radial forearm free flap after failure of initial free Jejunal autograft. Postoperative results were satisfactory in most patients and two patients expired in 8 days postoperatively because of carotid blow out by chronic inflammation.

Ankle sprain is one of the most common musculoskeletal injuries. Although most ankle sprains respond well to conservative measures, chronic instability following an acute sprain has been reported to occur in 20% to 40% of patients. Some individuals are eventually indicated for a lateral ankle ligament reconstruction due to persistent ankle instability. More than 80 surgical procedures have been described to address lateral ankle stability. These range from direct repair of the anterior talofibular ligament (ATFL) and of the calcaneofibular ligament (CFL) to reconstructions based on the use of autograft or allograft tissues. However, the best surgical option remains debatable. The modified $Brostr{\ddot{o}}m$ procedure is most widely used for direct ligament repair, but not always possible because of the poor ATFL or CFL quality or deficiency of these ligaments, which prevents effective shortening imbrication. Furthermore, the importance of a CFL reconstruction has been emphasized recently. On the other hand, it is difficult to achieve an efficient CFL reconstruction during the $Brostr{\ddot{o}}m$ procedure. Others have reported that an anatomic reconstruction of injured ligaments restores the normal resistance to anterior translation and inversion without restricting subtalar or ankle motion, and as a result, anatomic reconstructions for lateral ankle instability utilizing an autograft or allograft tendon have gained popularity.

The authors reviewed 49 cases(48 patients) of benign bone tumor who had surgical treatment with xenograft at department of orthopedic surgery, Seoul National University Hospital from May, 1980 to May, 1994. Materials consist of 21 males and 27 females. The mean age at operation was 20.1 years(range : 4 -55 years) and the mean follow up period was 25.4 months(range : 7 - 85 months). We did xenograft only in 34 cases and xenograft mixed with autograft in 15 cases(14 cases, from ilium, 1 case from femur). The used materials for xenograft were $Lubboc^{(R)}$ in 29 cases, $Surgibone^{(R)}$ in 17 cases and $Pyrost^{(R)}$ in 3 cases. The average durations when bony union was achieved in radiograph were 13.8 weeks in whole cases, 12.5 weeks(range : 8 - 24 weeks) in $Lubboc^{(R)}$ graft cases and 15.7 weeks(range : 6 - 24 weeks) in $Surgibone^{(R)}$ graft cases. The tumor recurred in 4 cases, 1 case was recurred giant cell tumor at distal femur treated with mixed auto and $Lubboc^{(R)}$ graft and 2 cases were large cystic lesions at the proximal humerus diagnosed as simple bone cyst and at distal tibia diagnosed as fibrous dysplasia treated with $Surgibone^{(R)}$ graft and 1 case was aneurysmal bone cyst of the proximal tibia treated with $Lubboc^{(R)}$ graft. Wound infection occurred in 1 case. More transfusion was done in the cases that the lesion was larger than 5cm, the lesions were in the ilium or femur and the cases that were treated with mixed with autograft. This study implies that benign bone tumor is successfully treqated with curettage and xenograft or xenograft mixed with autograft. And also this method will reduce morbidity of donor site, intraoperative bleeding and post-transfusion complications.
