The purpose of this study is to access and describe the status of patients with untreated anterior cruciate ligament ruptures to determine if prediction of functional deterioration in these knees were inevitable. 29 patients with rupture of the anterior cruciate ligament verified arthroscopically were evaluated at an average of 3 years and 8 month after injury. This group of patients was selected by the retrospective review in patients who were treated with traumatic ligament injury of the knee joint. The average age at the injury time was 25.9 years ranged from 16 to 44 years and most of injuries occured during sports activities including 12 cases (4196) occured while the patients were playing football. Meniscal lesions were found in 21 cases(72.4%) of all 29 cases of which were 15 cases in the medial, 4 in the lateral and 2 in both side. Follow up functional average score using the Hospital for Special Surgery Knee was 35.8 which would be fall in the Fair range defined as moderate functional disability and depending on the condition of thigh muscle, the functional score was 38.3 in case of less than 2cm atropy of the thigh on the involved side and 32.6 in case of more than 2cm atrophy. There was statistically significant difference (p < 0.05) of the functional score. Reinjuries of the same knee joint were experienced in 22 cases (76%). Rehabilitation of thigh muscles would play an important part in recovery from the injuries.

Cholangiocarcinoma has been associated with various fibrocystic diseases of liver and biliary tract, but cholangiocarcinoma in polycystic liver disease (PLD) was extremely rare. It was reported that the prognosis of cholangiocarcinoma associated PLD was very poor and distant metastases were common. We report a rare case of intrahepatic cholangiocarcinoma associated with PLD in 58- year- old female who presented vague abdominal pain. She had also polycystic kidneys with normal renal function. MRI showed well demonstrated tumor with central scar and a adjacent large cyst in the left lobe of the liver. She underwent extended left lobectomy. On microscopic examination, the tumor was moderately differentiated cholangiocarcinoma having abundant fibrous stroma and necrosis and the adjacent cyst showed focal in situ carcinomatous changes in the lining epithelium.

A 49 years old male patient who suffered from deterioration of posterior neck pain, left hand numbness, left lower limb pain and gait disturbance for 3 years visited our outpatient department. He had been diagnosed as non-dysraphic cervical intradural lipoma and operated in August 1990. On the radiologic images, we found the regrowth of non-dysraphic cervical intradural lipoma from C2 to C7 level, which surrounds and compresses the cervical spinal cord. Previous subtotal laminectomy from C2 to C7 and severe cervical lordosis were also found. Appropriate debulking of lipoma mass without duroplasty was successfully done with intraoperative neurophysiological monitoring (IONM). We are following up the patient for 24 months via outpatient department, his neurologic symptoms such as hand numbness, gait disturbance, left lower limb pain and posterior neck pain have improved. We describe a rare case of regrowth of non-dysraphic cervical intradural lipoma.

OBJECTIVE: Anterior cervical discectomy and fusion (ACDF) is a choice of surgical procedure for cervical degenerative diseases associated with radiculopathy or myelopathy. However, the patients undergoing ACDF still have problems. The purpose of the present study is to evaluate the radiologic results of 3 different methods in single-level ACDF. METHODS: We conducted a retrospective collection of radiological data from January 2011 to December 2014. A total of 67 patients were included in this study. The patients were divided into 3 groups by operation procedure: using stand-alone cage (group cage, n=20); polyether-ether-ketone (PEEK)-titanium combined anchored cage (group AC, n=21); and anterior cervical cage-plate (group CP, n=26). Global cervical lordosis (C2-C7 Cobb angle), fused segment height, fusion rate, and cervical range of motion (ROM) were measured and analyzed at serial preoperative, postoperative, 6-month, and final 1-year follow-up. RESULTS: Successful bone fusion was achieved in all patients at the final follow-up examination; however, the loss of disc height over 3 mm at the surgical level was observed in 6 patients in group cage. Groups AC and CP yielded significantly better outcomes than group cage in fused segment height and cervical ROM(p=0.01 and p=0.02, respectively). Furthermore, group AC had similar radiologic outcomes to those of group CP. CONCLUSION: The PEEK-titanium combined anchored cage may be a good alternative procedure in terms of reducing complications induced by plate after ACDF.

OBJECTIVE: The purpose of this prospective study was to evaluate the effects of body mass index (BMI) on intra-abdominal pressure (IAP) and intraoperative blood loss (IBL) during lumbar spinal surgery. METHODS: Thirty patients scheduled for single level posterior lumbar interbody fusion were allocated equally to a normal group (Group 1, BMI;18.5-22.9 kg/m2), an overweight group (Group 2, BMI; 23-24.9 kg/m2), and an obese group (Group 3, BMI; 25.0-29.9 kg/m2) according to BMI. IAP was measured using a urinary bladder catheter; 1) supine after anesthesia induction, 2) prone at skin incision, 3) prone at the end of surgery. In addition, IBL was also measured in the three groups. RESULTS: IAP in the supine position was not significantly different in groups 1, 2, and 3 (2.7 mm Hg, 3.0 mm Hg, and 4.2 mm Hg, respectively) (p=0.258), and IAP in the prone position at incision increased to 7.8 mm Hg, 8.2 mm Hg, and 10.4 mm Hg, respectively, in the three groups, and these intergroup differences were significant, especially for Group 3 (p=0.000). IAP at the end of surgery was slightly lower (7.0 mm Hg, 7.7 mm Hg, and 9.2 mm Hg, respectively). IBLs were not significantly different between the three groups. However, IBLs were found to increase with IAP in the prone position (p=0.022) and BMI (p<0.05). CONCLUSION: These results show that BMI affects IAP in the prone position more than in the supine position during lumbar spinal surgery. In addition, IBLs were found to increase with IAP in the prone position and with BMI. Thus, IBLs can be expected to be higher in morbidly obese patients due to an increased IAP.

Intradural extramedullary (IDEM) ependymomas occur very rarely and little has been reported about their clinical characteristics. The authors present a case of a 57-year-old woman with an IDEM ependymoma. She was referred for the evaluation of a 4-month history of increasing neck pain and muscular weakness of the left extremities. Magnetic resonance imaging (MRI) of the cervical spine demonstrated an IDEM tumor with spinal cord compression. At the time of surgery, an encapsulated IDEM tumor without a dural attachment or medullary infiltration was noted, but the tumor capsule adherent to the spinal cord and root was left in place to minimize the risk of neurological sequelae. Histologic examination revealed a benign classic ependymoma. The post-operative course was uneventful and radiotherapy was performed. The patient showed an excellent clinical recovery, with no recurrence after 5 years of follow-up.

We describe a 75-year-old man with a cervico-thoraco-lumbar spinal epidural abscess was extended to the psoas muscle. The patient complained high fever and back pain, followed by weakness of the lower extremities. He had received multiple epidural injections in a local pain clinic just few days before the onset of fever. The multi-segmental epidural abscess which was demonstrated by MRI compressed dural sac and cord. The best way to recommend him was to undergo a surgical decompression, but he refused the surgery. Next, we chose nonsurgical treatment such as longstanding parenteral antibiotic therapy and percutaneous drainage of psoas abscess. We could cultivate a causative organism and chose appropriate antibiotics. The patient experienced immediate relief of fever and the improvement of laboratory findings, gradual relief of back pain and full neurological recovery.

Syringomyelia associated with tuberculous meningitis is an extremely rare condition. Only a few studies have reported clinical experience with syringomyelia as a late complication of tuberculous meningitis. Twenty-six years after a tuberculous meningitis episode, a 44-year-old man presented with progressively worsening spastic paresis of the lower limbs and impaired urinary function for 2 years. Radiological examination revealed syringomyelia extending from the level of C2 to T9 and arachnoiditis with atrophy of the spinal cord between C2 and T3. We performed laminectomy from C7 to T1, dissected the arachnoid adhesion and placed a syringo-pleural shunt via keyhole myelotomy. One year after the operation, his neurological condition improved. The postoperative control magnetic resonance imaging revealed the correctly located shunt and significantly diminished syringomyelia cavities. We aim to discuss the mechanism of syrinx formation following tuberculous meningitis and to share our surgical therapeutic experience with this rare disease entity.

A 33-year-old male presented with an acute onset of back pain and abdominal pain. He was 189.9 cm tall and had an arm span of 194 cm, and had mild pectus carinatum as well as arachnodactyly. Plain radiographs showed kyphoscoliosis of the lumbar spine, bamboo spine of the thoracic spine, and sacroiliitis of the pelvis. Abdominal computed tomography revealed debakey type 3 aortic dissection. We prescribed beta blockers to control his blood pressure. According to the modified New York criteria, we diagnosed him with HLA negative ankylosing spondylitis and initiated therapy with nabumetone and sulfasalazine. We later diagnosed Marfan syndrome based on the Ghent criteria and mutation screening at the fibrillin-1. After treatment, he has been followed up without symptoms or complications.
