The cases of 128 humeral fractures were evaluated at the Department of Orthopedic Surgery, Chosun University Hospital, during the six year period from January 1974 to December 1979 and the following results were obtained. 1. The high incidence of the humeral fracture was found under the age of 30 years and the sex ratio between the male and female was 3.6:1. 2. The most common causes of injuries were fallen down on the ground (36.7%) and the nexts were traffic accidents (34.4%). 3. Among the 128 cases of fractures, humeral shaft fractures were 33 cases (32%) under the age of 40 years and 47 cases (67.1%) of supracondylar fractures under the age of 20 years and 6 cases (54.5%) of neck fractures over the age of 60 years were noted. 4. The shapes of humeral fractures found out transverse fracture in 31 cases (65.9%) and the short oblique or spiral fracture in 35 cases (71.4%). 13 cases were combined with the open would to the fracture site (10.2%). 5. In the Correlation between the age and the union rate, sound union was more rapid under the age of 20 years than the aged person. Delayed unions were revealed 5 cases in transverse fractures, 2 cases in spiral fractures and 2 cases of nonunions were experienced on both segmental and transverse fracture of the shaft (1.6%). 6. The radial nerve paralysis revealed 5 cases (10%) at the shaft fracture and 2 cases (4.3%) Volkmanns ischemic contracture, 2 cases (4.3%) of cubitus varus, 2 cases (4.3%) of cubitus valgus were experienced on the complicution in there 47 cases of supracondylar fractures.

Two cases of tendon transfer for paralysis of the radial nerve due to trauma in the humerus have been operated by transferation of foream flexors such as flexor carpi radialis, pronator teres and palmaris longus at the Department of Orthopedic Surgery, Chosun University Hospiatl. The one case was a open fracture at midshaft of the humerus with cut down the radial nerve in the distal third of the humerus and with contaminated severe muscle injuries. The other case was radial nerve injury at the level of supracondylar area of humerus by the wound of deep laceration. The operative procedure carried out two month later after neurorrhpy of the radial nerve. However, the result of these cases were exhibited very good motor and sensory function of the radial nerve during two year follow up study. A review of literatures is included.

After dual plating with a locking compression plate for comminuted intraarticular fractures of the distal humerus, the incidence of ulnar nerve injury after surgery has been reported to be up to 38%. This can be reduced by an anterior transposition of the ulnar nerve but some surgeons believe that extensive handling of the nerve with transposition can increase the risk of an ulnar nerve dysfunction. This paper reports ulnar nerve injuries caused by the incomplete insertion of a screw head in dual plating without an anterior ulnar nerve transposition for AO/OTA type C2 distal humerus fractures. When an anatomical locking plate is applied to a distal humeral fracture, locking screws around the ulnar nerve should be inserted fully without protrusion of the screw because an incompletely inserted screw can cause irritation or injury to the ulnar nerve because the screw head in the locking system usually has a slightly sharp edge because screw head has threads. If the change in insertion angle and resulting protruded head of the screw are unavoidable for firm fixation of fracture, the anterior transposition of the ulnar nerve is recommended over a soft tissue shield.

OBJECTIVE: To evaluate the relationship between amniotic fluid interleukin-8 and the presence, severity and pattern of acute inflammatory lesions in the placenta delivered after preterm labor with intact membranes. METHODS: The relationship between placental histologic finding and amniotic fluid interleukin-8 was examined in 46 consecutive patients who were admitted with the diagnosis of preterm labor with intact membranes and who delivered singleton gestations within 5 days. RESULTS: The prevalence of acute histologic chorioamnionitis was 63.0%(29/46) and that of positive amniotic fluid culture was 17.4%(8/46). The most frequent site of histologic inflammation was chorion-decidua(56.5%, 26/46). The median amniotic fluid interleukin-8 increased significantly according to the presence and higher severity of inflammation in each type of placental section (p<0.05 for each). Three patterns of inflammation were identified in chorion-decidua: non-marginating, marginating, and mixed. Median amniotic fluid interleukin-8 and the rate of severe histologic chorioamnionitis (grade> or = 4) increased significantly in the order of non-marginating, marginating, and mixed (p<0.05 for each). CONCLUSION: Both the presence and greater severity of acute histologic chorioamnionitis are associated with an elevated amniotic fluid interleukin-8. A marginating and mixed pattern of inflammation are associated with a higher amniotic fluid interleukin-8. Amniotic fluid interleukin-8 is a reliable prenatal marker of histologic chorioamnionitis.

Inactivation of tumor suppressor genes may play an important role in many human cancers including breast. This study was done to determine the relationship between the expression of p53 and Rb protein and prognostic factors such as histopathologic differentiation, tumor size, and lymph node metastasis. In 57 cases of breast invasive ductal carcinomas, the immunohistochemical staining with p53 and Rb protein gave the following results: p53 protein was detected in 45.6% (26/57) of cases. Tumors with large size, poor differentiation or lymph node metastases tended to show increased expression of p53 protein. However, p53 protein expression did not show any significant correlation with prognostic factors such as tumor size (p value 0.25), histologic grade (p value 0.75), and positive lymph node status (p value 0.26). Rb protein was detected in 57.9% (33/57) of cases. Rb protein also did not show any significant correlation with prognostic factors such as tumor size (p value 0.56), histologic grade (p value 0.71), and positive lymph node status (p value 0.98). There was no significant correlation between p53 expression and Rb protein expression (p value 0.80).

Traumatic spondylolisthesis of the axis is the fracture of both pedicles and is called commonly as hangman' s fracture. The fractures with the anterior displacement more than 3mm and the angulation, more than 11 degrees were classified as unstable and the surgical methods were recommended for the treatment of the fractures. As for the surgical methods, anterior C2-3 fusion with plate fixation or transpedicular screw fixation were used. However, the differences between the clinical results of both methods were not reported in the literatures. In order to clarisy the clinical results of both methods, the authors evaluated the clinical results of 11 patients treated by anterior plate fixation and 7 patients treated by transpedicular fixation who were operated on between Mar. 1987 and,Jan: 1992. Minimum follow-up period was 12 months. 1. As the surgical complications, two cases of transient dysphagia in anterior fixation group and three cases of malinserted screw in transpedicular fixation group were observed. 2. Limitation of rotatory neck motion, less than 20 degrees in one direction was observed in four cases of transpedicular fixation group. 3. Anterior angulation, more than 10 degrees was noted in three cases of transpedicular group. 4. Mild intermittent neck pain was observed in two cases of anterior fixation group and two cases of transpedicular fixation group. Constant neck pain was present in three cases of transpedicular fixation group. 5. Over-all clinical results were excellent or good in all of anterior fixation group, and in four of seven transpedicular group. Although the clinical materials were limited in number, method of anterior plate fixation was recommended by the authors in the management of traumatic spondylolisthesis of axis, because of the easier technique and the better clinical results than the transpedicular screw fixation.

The branch retinal vein occlusion is the second most common retinal vascular disease after diabetic retinopathy. Complications such as macular edema, retinal neovascularization, vitreous hemorrhage, epiretinal membrane may be associated. But, the retinal detachment may occur rarely in BRVO patients. We studied the clinical features of retinal detachment associated with branch retinal vein occlusion. We reviewed the medical records of 15 retinal detachment patients associated with branch retinal vein occlusion. Mean age was 54.7 years old and 10 patients(66.7%) were female. Hypertension was associated in 13cases(86.7%). The duration between the development of BRVO and the development of retinal detachment was shorter than 4 years in all cases and shorter than 2 years in 9 cases(60.0%). Retinal break was identified in 14 cases(93.3%), among which 13 cases(92.2%) were located inside the lesion of branch vein occlusion. The epiretinal membrane was frequently combined 8 cases(53.3%). The preoperative laser photocoagulation was done in 4 cases(26.7%). The primary surgical procedures included scleral buckling in 8 cases(53.3%), pars plana vitrectomy in 6 cases(40.0%), and scleral buckling with pars plana vitrectomy in 1 case(6.7%). Three cases(20.0%) required reoperations. The postoperative complications included the progression of cataract in 6 cases(40.0%), iatrogenic retinal tear in 3 cases(20.0%), epiretinal membrane in 2 cases(13.3%), and proliferative vitreoretinopathy in 1 case(6.7%). The anatomic retinal reattachment was achieved in 14 cases(93.5%) and the visual recovery in 11 cases(73.3%).

Cockayne syndrome is a rare autosomal recessive disorder that results in postnatal growth failure and progressive neurological dysfunction. Associated clinical features are gait disturbance, progressive pigmentary retinopathy and other ocular anomalies such as cataracts and optic disk atrophy, sensorineural hearing loss, dental caries and cutaneous photosensitivity. The disease is clinically heterogeneous with a wide range in the type and severity of symptoms. We experienced a case of Cockayne syndrome in 13 year-old male, who had delayed development, hypophasia, characteristic physical appearance, cutaneous photosensitivity, dental caries. We reported the case with review of literatures.
