The Journal of the Korean Orthopaedic Association 1988;23(4):1195-1200
Internal fixation of fractures always represents a race between the time required for bone healing and the inevitable fatigue failure of implant. The authors clinically analyzed the cause of metal failure in 34 cases at Department of Orthopedic surgery, Taegu Medical Center from Jan. 1981 to Dec. 1987. 1. Metal failure occured in 29 compression plates, 1 Kuntscher nail, 1 Jewett nail, 1 Ender nail, and 2 semitubular plates. 2. Involved bones were the femur in 28 cases, tibia in 3 cases, humerus in 1 cases, and the ulna in 2 csses. 3. The time interval between internal fixation and metal failure was average 7 months. 4. The cause of metal failure was deficiency of medial buttress in 14 cases and incorrect position of implant in 19 cases, and incorrect selection of implant in 1 case. 5. (Autogenic) Bone graft was not performed in the primary surgical treatment of 31 cases.

Infected nonunion continues to be a major therapeutic challenge. Twenty-five cases of infected nonunion of tibia were trested by Papineau's cancellous bone graft at Department of Orthopedic Surgery, Taegu Medical Center from Jan. 1981 to Dec. 1987. The results were as follows. 1. Decortication, sequestrectomy and cancellous bone graft were performed simultaneously in every case. 2. Osseous union and eradication of infection were obtained at average 8 months.

Split thickness skin graft can be used as a one stage procedure for the immediate treatment of friction avulsion injuries in severe foot injuries. After cleaning the wound, a split thickness skin graft is taken from thigh and cover the wound. We have treated 6 patients with friction avulsion injuries of the foot.

9.Clinical observation of the bilateral branch vein occlusion.

The clinical evaluation was done in eight eyes of four patients with bilateral branch retinal vein occlusion. The onset of age was from 36 to 65 years, and three pa dents were women. Hypertension was the most common associated systemic disease. Retinal neovascularization was complicated in six eyes, and five eyes had vitreous hemorrhage. The vitrectomy was performed in three eyes. We believe that branch retinal vein occlusion associated with hypertension should be followed carefully in the fellow eyes.

The authors performed experimental study to produce proliferative vitreoretinopathy by intravitreal injection of homologous fibroblasts in pigmented rabbits. Twenty four eyes of 12 rabbits were divided into control and experimental groups. In experimental group, the eyes were pretreated with expanding gas, perfluoropropane for the vitrectomy. In control group, no such procedure was preceded. In both groups, 5.0×10⁴, 1.0×10⁵ and 1.5×10⁵ cells of homologous fibroblasts were injected into the vitreous cavity. All the eyes were observed regularly with indirect ophthalmoscope followed by fundus photography. Those eyes were enucleated in 1, 2, 4 weeks for the light and electron microscopic studies. The development and severity of the proliferative vitreoretinopathy were correlated with the numbers of the injected fibroblast. This was more pronounced in the experimental group.
