Pseudoaneurysm arising from the superficial temporal artery (STA) is a rare and potentially critical cause of palpable mass. Most pseudoaneurysms form as a result of blunt trauma and present as painless, pulsatile mass that may be associated with pathologic finding and enlarged size. We report a rare case of pseudoaneurysm arising from STA caused by blunt injury and diagnosed by 3-dimensional computed tomography (CT) angiography.

In the distal third of the tibia, the anterior tibial artery runs close to the anterolateral surface of the tibial cortex. In a clinical situation, without vascular evaluation, injury or entrapment of the anterior tibial artery is difficult to detect. Because, an intact dorsalis pedis pulse is supplied with the collateral vessels of the posterior tibial artery. An entrapped anterior tibial artery can be injured during closed reduction in an emergency room or open reduction and internal fixation in the operating room. Care must be taken to prevent iatrogenic anterior tibial artery. In this case, an entrapped anterior tibial artery was observed in a simple radiograph and computed tomograph without contrast media for the vessel. We report on a rare case of calcified anterior tibial artery entrapment in a distal tibial fracture.

STUDY DESIGN: Retrospective study OBJECTIVES: To evaluate the results of a serial pulmonary function test in severe scoliosis that required an anterior release and posterior fusion SUMMARY OF LITERACTURE REVIEW: There are a few reports on the pulmonary function after an anterior release and posterior fusion in severe scoliosis. MATERIALS AND METHODS: Twenty two cases of severe scoliosis requiring an anterior release and posterior fusion were followed up more than 2 years. The patients were divided into two groups (group 1: 10 cases of open thoracotomy and posterior fusion, group 2: 12 cases of thoracoscopic release and posterior fusion). The forced vital capacity (FVC), forced expiratory volume 1 (FEV1), total lung capacity (TLC), the predicted FVC, predicted FEV1 and predicted TLC in the preoperative, 3 month, 6 month, 1 year, 2 year postoperative period in the two groups were compared. Statistical analysis was performed using a paired T-test. RESULTS: The average preoperative FVC in groups 1 and 2 were checked as 2.20 L and 2.30 L, respectively. The postoperative 3 month FVC were checked as 1.60 L and 1.81 L, respectively, which were the lowest levels throughout the serial follow-up. The postoperative 6 month FVC were 1.70 L and 2.15 L, respectively. The postoperative 2 year FVC were 2.17 L and 2.18 L, respectively, which were 98.6% and 94.8% of the preoperative FVC. The average preoperative FEV1 of group 1 was 1.95 L. The post-operative 3 month FEV1 were at the lowest level and the postoperative 2 year FEV1 was 1.80 L (92.3% of preoperative value). The average preoperative FEV1 of group 2 was 2.05 L. The postoperative 6 month FEV1 was 1.90 L (92.7% of preoperative value). The TLC of group 2 showed a faster recovery than that of group 1. The predicted FVC, FEV1 and TLC of both groups at 2 years after surgery were 2 ~4% lower than the baseline. The recovery pattern in group 1 was steady for 2 years. The postoperative 6-month value was similar to the postoperative 2-year value in group 2. CONCLUSIONS: In severe scoliosis with a decreased pulmonary function, those undergoing thoracoscopic anterior release had a faster pulmonary function recovery than those undergoing an open thoracotomy.

PURPOSE: To predict the development of a neurogenic bladder based on an analysis of the clinical and radiological findings in patients with lumbar disc herniations. MATERIALS AND METHODS: Twenty-six patients, who were suspected of having neurogenic bladders, underwent urodynamic testing. The anteroposterior diameters and the cross-sectional areas of the dural sacs at the herniated disc levels were measured by magnetic resonance imaging. Clinically, we evaluated lower back pain, radiating pain, saddle anesthesia, bladder function, motor weakness of the lower limbs, and the Japanese Orthopaedic Association (JOA) score. RESULTS: Thirteen (50%) of the 26 patients were diagnosed with positive neurogenic bladders. The average anteroposterior diameters of the dural sacs in group I (13 cases) with positive neurogenic bladders and in group II (13 cases) with negative neurogenic bladders, were 6.8 (range, 4-9) mm and 9.0 (range, 8-10) mm, respectively (p<0.001). When an anteroposterior diameter of 7 mm was used as the threshold value for differentiation between the anteroposterior diameter of the dural sac and a neurogenic bladder, the sensitivity and specificity were 61.5% and 100%, respectively. The average cross-sectional areas of the dural sacs in group I and group II were 74.9 (range 50-96) mm(2) and 86.2 (range 60-103) mm(2), respectively (p=0.069). When a cross-sectional area of 77 mm2 was used as the threshold value for differentiation between the cross-sectional area of the dural sac and a neurogenic bladder, the sensitivity and specificity were 61.5% and 84.6%, respectively. All 9 patients who had saddle anesthesia were diagnosed with positive neurogenic bladders. However, there was no statistical significance between the preoperative JOA score and the development of a neurogenic bladder. CONCLUSION: The anteroposterior diameter of the dural sac and saddle anesthesia might be important factors in predicting the presence of a neurogenic bladder in patients with lumbar disc herniation.

Restoration of the hip biomechanics, including the femoral offset and leg length, are the desired goals when performing total hip arthroplasty. A leg length discrepancy following total hip arthroplasty is a significant source of back pain and sciatica, gait disorders, general dissatisfaction and dislocation. Significant lengthening of the leg can be a risk factor for nerve injury and it is a relatively common cause of litigation. There is a fundamental interrelationship between leg length and stability when performing hip arthroplasty. There are a multitude of situations in which achieving both stability and perfectly equal leg lengths is simply not possible. Stability is the primary objective, and the surgeon may need to sacrifice leg length equality on the altar of stability. Although a leg length discrepancy cannot be eliminated after hip arthroplasty, it can be minimized through a series of steps, including a physical examination, radiographic evaluation, preoperative templating and intraoperative confirmation of the preoperative plan.

BACKGROUND: To evaluate the clinical results and operation technique of arthroscopic repair of combined Bankart and superior labrum anterior to posterior (SLAP) lesions, all of which had an anterior-inferior Bankart lesion that continued superiorly to include separation of the biceps anchor in the patients presenting recurrent shoulder dislocations. METHODS: From May 2003 to January 2006, we reviewed 15 cases with combined Bankart and SLAP lesions among 62 patients with recurrent shoulder dislocations who underwent arthroscopic repair. The average age at surgery was 24.2 years (range, 16 to 38 years), with an average follow-up period of 15 months (range, 13 to 28 months). During the operation, we repaired the unstable SLAP lesion first with absorbable suture anchors and then also repaired Bankart lesion from the inferior to superior fashion. We analyzed the preoperative and postoperative results by visual analogue scale (VAS) for pain, the range of motion, American Shoulder and Elbow Surgeon (ASES) and Rowe shoulder scoring systems. We compared the results with the isolated Bankart lesion. RESULTS: VAS for pain was decreased from preoperative 4.9 to postoperative 1.9. Mean ASES and Rowe shoulder scores were improved from preoperative 56.4 and 33.7 to postoperative 91.8 and 94.1, respectively. There were no specific complication and no significant limitation of motion more than 10 degree at final follow-up. We found the range of motions after the arthroscopic repair in combined lesions were gained more slowly than in patients with isolated Bankart lesions. CONCLUSIONS: In recurrent dislocation of the shoulder with combined Bankart and SLAP lesion, arthroscopic repair using absorbable suture anchors produced favorable clinical results. Although it has technical difficulty, the concomitant unstable SLAP lesion should be repaired in a manner that stabilizes the glenohumeral joint, as the Bankart lesion can be repaired if the unstable SLAP lesion is repaired first.

Ossification of ligamentum flavum is a very rare disease and one of the new disease entities in myelopathy. We report three cases of ossification of ligamentum flavum in thoracic spine causing thoracic myelopathy. Main symptoms of this disease are numbness of both legs and feet, gait disturbance and spastic motor weakness. Simple spine X-ray, metrizamide myelogram, CT and MRI are most useful diagnostic tools. Sufficient decompressive laminectomy and facetectomy are treatment of choice.

PURPOSE: Gingko biloba extract (GBE), a natural product extracted from Gingko leaves, is known to increase the radiosensitivity of tumors. This radiosensitization probably arises from the increase in the peripheral blood flow by decreasing the blood viscosity and relaxing the vasospasm. The influence of a GBE on the metabolic status in fibrosarcoma II (FSaII) of a C3H mouse was investigated using 31P magnetic resonance spectroscopy (MRS). MATERIALS AND METHODS: Eighteen C3H mice with fibrosarcoma II (from 100 mm3 to 130 mm3) were prepared for this experiment. The mice were divided into 2 groups; one (9 mice) without a priming dose, and the other (9 mice) with a priming dose of GBE. The GBE priming dose (100 mg/kg) was administered by an intraperitoneal (i.p.) injection 24 hours prior to the measurement. First 31P MRS spectra were measured in the mice from each group as a baseline and test dose of GBE (100 mg/kg) was then administered to each group. One hour later, the 31P MRS spectra were measured again to evaluate the change in the energy metabolic status. RESULTS: In the group without the priming dose, the mean pH, PCr/Pi, PME/ATP, Pi/ATP, PCr/(Pi+ME) values 1 hour after the test dose were not changed significantly compared to the values at the baseline. However, in the group with the priming dose, the mean PCr/Pi, Pi/ATP, PCr/(Pi+PME) values 1 hour after the test dose changed from the baseline values of 0.49, 0.77, 0.17 to 0.74, 0.57, 0.28 respectively. According to the paired t-test, the differences were statistically significant. CONCLUSION: The above findings suggest that the metabolic status is significantly improved after administering GBE if the priming dose is given 24 hours earlier. This shows that the radiosensitizing effect of GBE is based on the increase of tumor blood flow and the improvement in the metabolic status.
