Experience in 19 cases (20 joints) of artificial elbow joint replacement was reported- 15 cases(16 elbow joints) were followed-up more than 25 months.A satisfactory result was obtained in 68.8% of case. This method of treatment has the merits of quick restoration of elbow joiut fuuction and good joint stability. The substituted joint is rather powerful and the range of movement approaches that of a natural one. The operative technique is easy to master.on the basis of follow-up study, the relation ship between the result of treatment and the material used was discussed. The indications and the technique of the operation were presented. The causes of faiture and unsatisfactory results were discussed.

This paper is to report the therapeutic results of 78 cases of gluteus maxi-mus paralysis resulting from poliomyelitis with the modified Ober's operation. 64 cases out of the 78 have been followed up for 2 years and 9 months on average. The whole course of the treatment was completed in 52 cases. Among them, 10 of the 14 cases walking with 2 crutches preoperatively could walk with only one after operation, 23 of the 25 cases walking with one crutch. before operation could walk with a limping leg but no crutch, and all the 13 cases walking with hand stabilization of the knee before operation could walk independently after operation. After the reconstruction, the strength of the muscle reached grade II in 37 cases, grade II+ in 16, and grade III in 11.In addition, the details of the modified Ober's operation were introduced, and the problems of the indications and staging of the operation and the mechanism of therapeutic efficiency were discussed.

BACKGROUND: MRI is generally considered as an important means to diagnose cervical disc herniation.OBJECTIVE: To explore the correlation between clinical manifestations of traumatic cervical disc herniation and MRI changes.DESIGN: A retrospective study.SETTING: Department of Orthopedics, Xinqiao Hospital of Third Military Medical University of Chinese PLA.PARTICIPANTS: We selected 123 patients with traumatic cervical disc herniation who came to the Department of Orthopedics, Xinqiao Hospital of Third Military Medical University of Chinese PLA, for treatment between June 1982 and June 2002. Their clinical manifestations fell into four types:of grade Ⅰ or Ⅱ, 14 of which lost motility with normal or slightly impaired icantly decreased or lost motility of the bilateral upper limbs with myotility of nificantly decreased motility and thignesthesia of the unilateral upper and impaired motility, decreased pain sensation of the lower limb on the opposite side, but with good myotility.METHODS: MRI examination was carried out in 123 cases of traumatic cervical disc herniation.MAIN OUTCOME MEASURES: The correlation between the clinical manifestations of 123 cases and MRI results.RESULTS: The clinical manifestations and MRI information of 123 cases verse-type herniation, clinically manifested as symmetric incomplete as central canal syndrome and significantly decreased or lost motility of the ripheral-type herniation, manifested as nerve root pain of unilateral side as well as pain sensation and thermesthesia on the opposite side.CONCLUSION: MRI typing suggests the segment, position and shape of disc herniation specified, and the 4 types of clinical manifestations indicate the consistency of anatomic location with the corresponding neural disorder.

This paper is to report our experience of using the internal fixation with compression-screw to treat 9 fractures of carpal navicular bone including two fresh) two old and 5 non- union cases.The mean follow-up time of the 9 cases was one year. Two fresh and 2 old fractures healed uneventfully and so did the 2 cases out of the 5 non-unions. The symptoms, however, disappeared in all the cases and the function of the wrist was or nearly was normal. All the patients resumed their original work.It is believed that this method of internal fixation with compression-screw is simple and easy to perform. Its effect is reliable. No external fixation is needed after the operation. And the function of the wrist can be restored after a short period of treatment.It is suggested that the indications of this operative treatment are non-union cases without ischemic necrosis, unstable fresh fractures with displacement and fractures in the proximal third or half of the navicular bone.
