The lumbosacral fusion has some problems because of it's biomechanical characteristics especially in the unstable spine of various causes and results considerable cases of pseudoarthrosis even with long immobilization. The conventional internal fixators for the spine are not adequate for the lumbosacral fixation with difficulty of sacral fixation maintaining lumbosacral lordosis and risk of the sacral nerves. Recently the pedicle screws and sacral screws connected to the plates or rods are known to be very effective and safe for the lumbosacral fixation permiting early mobilization and decreasing the incidence of pseudoarthrosis. Authors reviewed 10 cases of lumbosacral fusion with internal fixation using the long bone plates and screws which were managed since June 1986 at the department of orthopaedic surgery, Daegu Fatima Hospital and the followings were obtained. 1. The cases were 5 isthmic and 5 degenerative spondylolisthesis with enough spinal stenosis and instability before surgery or after decompression procedures having ages from 39 to 62 years old. 2. All cases had adequate decompression and bilateral intertransverse fusion combined with the internal fixation from 4th lumbar spine to sacrum. 3. Post-operative complications noted in 3 cases such as superficial infection, marginal skin necrosis, paralytic ileus, urinary difficulty and loosening of screws which were all improved without additional procedures. 4. There was no pseudoarthrosis at follow-up examination of 6 months to 1 year and 9 months in spite of a case of loosening of screws. 5. Ambulation was allowed in 2 weeks after surgery wearing lumbosacral corset and all satisfied the results having complete or significant improvement of the symptoms. 6. The internal fixation using long bone plates and screws for the lumbosacral fusion was considered to be effective with very low cost and good mobility.

Displaced intra-articular fractures of the calcaneus result in serious and prolonged disability. These injuries continue to pose a therapeutic challange and there remains a great deal of controversy regarding treatment, operative versus nonperative. The lateral approach for open reduction, popularized by Palmer, has been used by many authors, with high percentage of excellent results. We treated 21 displaced intra-articular fractures of the calvaneus in 18 patients by open reduction and internal fixation through the lateral approach from July 1990 to May 1992 and the patients have been followed from 12 to 36 months from the time of their injury. The clinical and radiographic analyses were as follows; 1. The most common cause of injury was falls from a height: 19 fractures in 16 patients(88.8%), Spine fracture was most commonly associated injury : 5 patients (27.8%). 2. Fracture was classified according to classification of Paley and Hall. Eight fractures were tongue type(no comminution 4, with comminution 4), 12 joint depression type(no comminution 8, with comminution 4), and a comminuted type. 3. The average bohler tuber-joint angle was

The displaced femoral neck fractures remain a major challenge to orthopaedic surgeons as the elderly population is increasing. Successful union by internal fixation after adequate reduction without avascular necrosis is primary goal since the functional results having own femoral head are much superior to those having prosthetic femoral head, but prosthetic replacement is indicated for some patients with fresh fractures who need early ambulation as well as neglected fractures and failed internal fixations. The early result after prosthetic replacement was known to be very satisfactory but the late complications are becomming the major problem. Authors reviewed 21 cases of the prosthetic replacements for the femoral neck fractures which were followed for more than one year and managed at Fatima Hospital during the years between 1975-1984 and the following results were obtained. 1. The cases were 8 males and 13 females having ages from 42 to 87 years with average 69 years old. 2. The cases were 11 elderly fresh fractures, 6 neglected fractures, 2 failed osteosynthesis and 2 others. 3. Moore and Thompson prosthesis were used and 13 of them were fixed with bone cement. 4. The early result evaluated at 3 months after surgery revealed satisfactory in 90% but the final result at average 3 years and 5 months ranging from 1 year to 6 years and 2 months revealed satisfactory results in 58% 5. There was no significant early post-operative complications. 6. The late complications were 8 cases of acetabular erosions and these were combined with stem loosening in 2, subsidence in 2 and deep infection in 1 case. 7. The late complications started to reveal at about 3 years after surgery and occurred in younger and active patient. 8. The prosthetic replacement for femoral neck fracture is recommended for the inactive patient or the patient with expected activity less than 3 years.

We report a patient with a ruptured vertebral artery (VA) dissecting aneurysm that was treated by internal trapping of the aneurysm and parent artery using detachable coils with subsequent antegrade recanalization of occluded vertebral artery during the follow-up period. A 38-year-old man was admitted with a ruptured right VA dissecting aneurysm just distal to origin of right posterior inferior cerebellar artery. The dissected segment of the VA was occluded by coil embolization. The 14 months follow-up angiography showed that dissected aneurysm was completely occluded, but the parent artery was recanalized in an antegrade fashion. Based on this unique case, the authors suggest that careful angiographic follow-up of dissecting aneurysm is required, even in patients successfully treated with endovascular occlusion of the affected artery and aneurysm.

Although posterior segmental fixation technique is becoming increasingly popular, surgical treatment of craniovertebral junctional disorders is still challenging because of its complex anatomy and surrounding critical neurovascular structures. Basilar invagination is major pathology of craniovertebral junction that has been a subject of clinical interest because of its various clinical presentations and difficulty of treatment. Most authors recommend a posterior occipitocervical fixation following transoral decompression or posterior decompression and occipitocervical fixation. However, both surgical modalities inadvertently sacrifice C0-1 and C1-2 joint motion. We report two cases of basilar invagination reduced by the vertical distraction between C1-2 facet joint. We reduced the C1-2 joint in an anatomical position and fused the joint with iliac bone graft and C1-2 segmental fixation using the polyaxial screws and rods C-1 lateral mass and the C-2 pedicle.

BACKGROUND: Totally implantable access port (TIAP) provides reliable, long term vascular access with minimal risk of infection and allows patients normal physical activity. With wide use of ports, new complications have been encountered. We analyzed TIAP related complications and evaluated the outcomes of two different percutaneous routes of access to superior vena cava. METHODS: All 172 patients who underwent port insertion with internal jugular approach (Group 1, n = 92) and subclavian approach (Group 2, n = 79) between August 2011 and May 2013 in a single center were analyzed, retrospectively. Medical records were analyzed to compare the outcomes and the occurrence of port related complications between two different percutaneous routes of access to superior vena cava. RESULTS: Median follow-up for TIAP was 278 days (range, 1-1868). Twenty four complications were occurred (14.0%), including pneumothorax (n = 1, 0.6%), migration/malposition (n = 4, 2.3%), pinch-off syndrome (n = 4, 2.3%), malfunction (n = 2, 1.1%), infection (n = 8, 4.7%), and venous thrombosis (n = 5, 2.9%). The overall incidence was 8.7% and 20.3% in each group (p = 0.030). Mechanical complications except infectious and thrombotic complications were more often occurred in group 2 (p = 0.033). The mechanical complication free probability is significantly higher in group 1 (p = 0.040). CONCLUSIONS: We suggest that the jugular access should be chosen in patients who need long term catheterization because of high incidence of mechanical complication, such as pinch-off syndrome.

BACKGROUND AND OBJECTIVES: Click-evoked myogenic potentials have been used as a clinical test of the vestibulospinal reflex (VSR) and a complementary test for determining the lesion site. But there have not been clear diagnostic criteria for the VEMP test, so its use has been limited. We compared the parameters of VEMP among the normal and vestibulopathy patients and clarified the diagnostic value of each parameter. MATERIALS AND METHODS: We compared the results of VEMP conducted in 14 healthy volunteers and 35 patients who had been diagnosed with unilateral vestibulopathy by the vestibular function test (VFT). As parameters of VEMP, latency, amplitude and interlatency were compared between the two groups. We got positive findings of VEMP according to each parameter. RESULTS: Twenty-four percent of the patients showed normal VEMP findings, but seventy-five percent of that patients showed abnormal findings. Absent VEMP formation, prolonged latency, especially p13, and decreased amplitude (increased VEMP asymmetry) were shown in significant proportions of the patients. CONCLUSION: VEMP is a clinically complementary diagnostic method of VFT for dizzy patients. Prolonged peak latency and increased VEMP asymmetry are diagnostically valuable in the evaluation of that test.
