A retrospective study on 218 patients indicated the ultrasound Doppler to diagnose the vascular pathology in the pelvic limb has shown that the image of ultrasound found the artherosclerosis in the major arteries, which frequently occurred in the patients with the blood supply insufficiency for limb during movement. The lesion of vasculitis and arterial thrombosis and embolism only located in the minor arteries and not found by ultrasound. When finding the lesion of artherosclerosis included thrombolism in the medium or major arteries, the patients should be indicated the angiography to identify and evaluate generally for next indications

Fractures of the humeral neck are relatively common, but their anatomical complexities make closed reduction difficult sometimes, and in case of reduction it is tough to maintain the position. Even open reduction of the fracture also faces multiple problems including poor functional recovery of the shoulder joint. The Department of Orthopedic Surgery of Seoul Adventist Hospital developed a device of external fixation for 13 humeral neck fractures. We used this method for displaced and unstable fractures of humeral neck from December 1987 to March 1989. Satisfactory results were obtained in 11 cases and poor results in 2 cases. We think our method is a effective useful way of treatment for humeral neck fractures, and its main advantages are as follows:1. Using proximal and distal bars, fracture can be easily reduced and firmly maintained. 2. Active motion exercise can be started early and functional recovery of the shoulder joint can be highly predictable. 3. It is quite convenient for treating combined fracture or external wound of same extremity.

OBJECTIVETo analyze the features, diagnosis and treatment of limb arterial injuries caused by traffic accidents.

METHODSA total of 43 patients with limb arterial injury admitted in our department over the past 30 years (about 50% of them happened during the last 10 years) were analyzed retrospectively in this article. The popliteal, femoral and brachial arteries were mainly involved, accounting for 43.2%, 20.5% and 20.5% respectively of all the involvements. There were 35 cases of open injury and 9 of close injury. The involved vessels were transected in 43.2% of the cases and contused in 40.9%. All the patients had various complications, such as fractures, dislocations and severe soft tissue injuries. The injured vessels were repaired by means of end-to-end anastomosis in 10 cases, autogenous vein graft in 23 cases and intraluminal hydraulic dilatation in 4 cases.

RESULTSSuccessful limb salvage was achieved in 34 cases initially, whereas 10 amputations were carried out due to injuries to popliteal arteries in 7, femoral arteries in 2 and humeral artery in 1 and severe soft tissue damages in 9 cases. Twenty-nine patients were followed up for 1-156 months, with the average of 48.8 months. There was good circulation in 22 cases and certain ischemia in 5 cases. Two amputations were carried out in the late stage because of popliteal artery thrombosis after repair in 2 cases. There was no death in this series.

CONCLUSIONSThe limb arterial injuries caused by traffic accidents are severe and complicated. It is proposed that particular attentions should be paid to the features in diagnosis and treatment for this type of injury and special efforts should be made for both life saving and limb salvage.

Heterotopic ossification (HO) is frequently seen on rehabilitation units after spinal cord injuries, fractures, brain injuries, and limb amputations. Currently, there is no effective treatment for HO other than prophylaxis with anti-inflammatory medications, irradiation, and bisphosphonate administration. These prophylactic treatments are not effective for managing ectopic bone once it has formed. Here we describe three cases of established neurogenic HO treated with radiation therapy (RT). All patients had decreased serum alkaline phosphatase (ALP) and bone-specific ALP levels with decreased pain but increased range of motion immediately after RT. Post-treatment X-rays revealed no further growth of the HO. All patients maintained clinical and laboratory improvements 4 or 6 months after the RT. Our results suggest that RT is safe and effective in decreasing pain and activity of neurogenic HO.

OBJECTIVE: To observe the changes of electrocardiogram and serum cardiac troponin I at the early stage of severe crush injury in rats. METHODS: Crush injury was produced in Sprague-Dawley rats. The changes of electrocardiogram were recorded with the standard II, the serum levels of cardiac troponin I were studied by automated chemiluminescence assay. RESULTS: The ST segment elevated considerably after crush injury and lasted 24 h, the levels of serum cTnI were much higher than those of the control groupes after 6 h of injury. CONCLUSION Cardiomyocyte injury was induced in the early phase of crush injury.

It is known that free-falling accident is one of the major causes of head or spinal injury, especially in the elderly and children. But, the frequent injury types are diverse according to the reports because of the different subjects studied among the reports. A cranio-spinal injury caused by free-falling accident from height hasn't been studied a lot in Korea yet. To evaluate the clinical aspects of cranio-spinal fracture caused by free-falling injury which developed particularly in a certain fixed place, we analyzed 122 patients who had had the fractures involving extremities, ribs, and cranio-spinal regions during the past 4 years from January 1994 through July 1997. Forty-seven patient(38.5%) had the cranio-spinal fracture. The incidence of the skull and vertebral body fracture were significantly higher than that of the vertebral transverse process fracture, respectively (p=.052 and p=.007). There was statistically insignificant in the height of falls between the skull and vertebral body fracture(p=.175). Associated extra- craniospinal fractures were noted on radius(25.4%), rib(20.5%), femur(9%), calcaneus(5.7%), and pelvic bone(4.9%), in order of frequency.

Radial artery aneurysm is an extremely rare disease and this is usually caused by iatrogenic trauma such as arterial cannulation. Most traumatic aneurysms in the extremities are false aneurysms and most cases have occurred at the level of the wrist. Very few true aneurysms of the radial artery have been reported, with most of them being iatrogenic. A right handed 38-year-old female had a true aneurysm of the distal radial artery in the thenar groove of the palm. The patient had a history of excessive handclapping and the injury was suggestive of repetitive occupational injury due to scissoring. She underwent surgical treatment for the aneurysm of the radial artery in the thenar groove of the palm of her hand.

BACKGROUND: Vascular injury has been increased with popular outside activities. However there are only a few studies for vascular trauma. We intended to find out the relationships between the vascular trauma and its prognosis. MATERIAL AND METHOD: Forty-four patients were diagnosed and operated on for vascular injury in the Gyeongsang National University Hospital from 1992 to 1999. We reviewed their chart and analysed their data retrospectively. We studied te causes, treatments, and prognoses of traumatic vascular injury. RESULT: The transfer time between accident place and emergency department was mean 3.5 hour, and the operation preparing time was 8.8 hours. Five cases required amputation of extremity. All amputation cases were combined with communited bony fractures. Thirty-eight cases had combined other injuries, and almost combined injuries were muscular and neurological damages. CONCLUSION: The optimal treatment plan for vascular trauma was prompt diagnosis and quick management. It may decrease amputation rate and post-traumatic complications. Therefore we must be carefully evaluated the multiple traumatic patients for early diagnosis of vascular injury and operate quickly in emergency status.

Using computerized motion analysis techniques, kinematics of foot trajectories were quantitatively analyzed in twelve rats before and after dorsal spinal cord hemisection at the T6 level. Although overground locomotion in these animals returned to normal within four weeks, some kinematic variables during treadmill locomotion did not recover to pre-lesion level. Immediately following dorsal hemisection, amplitudes of both hindfeet horizontal and vertical movements were dramatically reduces. However, in three weeks, the amplitudes of horizontal movement(stride length) became significantly larger than of pre-lesion strides. On the other hand, amplitude of hindlimb vertical movement showed very little recovery. Forelimb-hindmill coordination was also disrupted initially but returned to normal within three weeks. The duration of hindlimb swing phase became significantly longer after sectioning and gradually recovered, but never to pre-lesion levels. Interestingly, amplitudes of forelimb vertical movement. which was depressed initially, became significantly largery three weeks after lesioning. A dramatic increase in the statistical variation of limb kinematics, which persisted even after motor recovery, is an important parameter for the evaluation of neural deficits in spinal cord injuries. Kinematic analysis is a sensitive technique for the detection of minor motor deficits following nerve injuries.
