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.

A statistical survey was made on 729 inpatients during the period of 4 years and 9 months, 1961-1965, in the Department of Urology, The First Army Hospital, in reference to age distribution, monthly distribution on various diseases of the genitourinary tracts and operative procedures.The tables in the text represent the result of the observation and are summarized as follows: The majority of the patients (85%) was distributed between the ages 21 and 26. Of 729 in patients, there were 270 cases (37%) of genito-urinary tuberculosis, 84 cases (11.5%) of urinary calculus,69 cases of trauma and 60 cases of non-specific urinary tract infection. There were 379 operative procedures including 91 nephrectomies, and 108 epididiymectomies.

This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.

Thirty-eight patients with urethral injury treated during the period from January 1962 to August 1964 have been studied in particular reference to sexual ability following injury and the results are summarized as follows: 1. The incidence of urethral injury was 6.8% of the total inpatients and the average in age was 23.8 years. Twenty-three cases (61.5%) were accompanied by pelvic fracture. 2. The incidence of impotence following injury was 47%, 36.4% temporary and 11.0% permanent. 3. Of 14 cases of temporary impotence, urethral injury was accompanied by pelvic fracture in 11 and all 4 cases of permanent impotence followed urethral injury accompanied by pelvic fracture. 4. Of fourteen cases of temporary impotence, previous urethral injury was complete in 6 and incomplete. in 8. Four cases of permanent impotence followed 3 complete urethral injury and one incomplete urethral rupture. 5. The average interval between the reception of trauma and the recognition of impotence was 3 to 5 months.
