RESUMEN
Objectives@#To report our experience of a patient in her 20s with multiple contiguous osteoporotic compression fractures.Summary of Literature Review: It is uncommon to develop multiple contiguous osteoporotic compression fractures at a young age. @*Materials and Methods@#A 26-year-old woman was admitted with lower back pain. On radiologic examinations, compression fractures of L1, L2 and L5 were observed. Bone mineral density testing indicated severe osteoporosis. Secondary osteoporosis was suspected, and further examinations were performed. The patient was diagnosed with adrenocorticotropic hormone–independent Cushing’s syndrome.On abdominal computed tomography, a tumor suspected to be an adenoma was observed on the left adrenal gland. Tumor resection surgery was then performed. @*Results@#Pathologic findings confirmed that the tumor was an adenoma. The lumbar fractures had healed at 3 months after the fracture. @*Conclusions@#If osteoporotic lumbar compression fracture occurs in a young patient, secondary osteoporosis should be suspected and the underlying cause must be found and treated.
RESUMEN
Objectives@#The purpose of this study was to assess the source and quality of information regarding cervical disc herniation available to patients on websites.Summary of Literature Review: Studies have shown that 92% of the Korean population regularly accesses and searches for medical information on websites. While a large amount of information exists on websites, there is a possibility that patients will be misled due to inaccurate information because there are no established criteria for qualitative evaluation. In addition, little research has been conducted on websites that provide information about cervical disc herniation. @*Materials and Methods@#The search term ‘‘cervical disc herniation’’ was entered into the three most popular search engines in Korea (Naver, Daum, and Google). The first 50 websites displayed by each engine were selected for inclusion in this study and were categorized as academic, commercial, physician, non-physician, government organization, and unspecified. Information was assessed in terms of DISCERN, accuracy, and exhaustivity scores, and a total summary score was calculated for each website. @*Results@#Among the theoretical total of 150 websites, 83 unique and relevant websites were identified. The distribution by source was as follows: non-physician, 34.9%; physician, 27.7%; commercial, 13.3%; unspecified, 10.8%; academic, 9.6%; and government, 3.6%. Academic and government websites obtained the highest total summary scores, with statistical significance when compared to other types (p=0.03). @*Conclusions@#Website information on cervical disc herniation is generally limited. Institutional improvement efforts are needed to foster an environment where patients can receive high-quality medical information, and physician groups should play a central role in this process.

PURPOSE: This study examined the effects of beraprost sodium on digital infrared thermal images in patients with peripheral arterial disease caused by type 2 diabetes mellitus. MATERIALS AND METHODS: Twenty-five diabetic patients with peripheral arterial disease were treated with beraprost sodium in a prospective, multicenter, cohort study from February 2013 to December 2014. Beraprost sodium (40 μg) was administered orally 3 times daily (120 μg/day) for 6 months. The visual analogue scale (VAS) and digital infrared thermal imaging (DITI) were performed to compare the blood flow improvement between before and after dosing. RESULTS: Among the 25 patients included in the evaluation, 22 patients completed the study. A significant increase in body temperature was observed in the front and left side, particularly in the plantar side in DITI compared to that before and after administration. An increase in body temperature was observed at the frontal part from 28.1℃±2.3℃ to 29.1℃±2.1℃ (p=0.021), at the left side from 27.8℃±2.4℃ to 28.6℃±1.9℃ (p=0.028), at the plantar part at 24.0℃±1.5℃, and at the plantar part at 27.1℃±2.4℃ (p < 0.01). The VAS decreased significantly from 5.4±1.3 to 2.7±2.0 after 6 months of treatment (p < 0.01). CONCLUSION: Beraprost sodium is a safe and easy-to use oral medication for diabetes peripheral arterial disease. It can be expected to increase the blood flow and decrease the lower extremity pain statistically after being taken for 6 months.

PURPOSE: The purpose of this study is to present the effective design of N-plasty of the iliotibial band and surgical results of its use as a treatment for refractory external snapping hip. MATERIALS AND METHODS: We evaluated 17 patients (24 cases) with external snapping hip who underwent N-plasty between October 2013 and May 2016 and who were followed up for at least 12 months. All patients were male and the mean age was 20.8 years. The mean duration of symptoms prior to surgical intervention was 28.5 months with an average follow up of 24.5 months. Surgery was defined as being successful when patients could carry out their daily activities and exercise without a clicking sensation or pain 6 months after surgery until their last follow-up. Failure was defined when either a clicking sensation or pain was present. The visual analog scale (VAS) and modified Harris hip score (mHHS) were measured and compared preoperatively and at last follow-up. RESULTS: All patients had complete resolution of pain and snapping. The VAS decreased from 6.77 preoperatively to 0.09 postoperatively and mHHS improved from 69.5 to 97.8 after surgery. CONCLUSION: Modified designed N-plasty is considered to be an excellent treatment method facilitating operation reproducibility with maximum elongation effect of the iliotibial band.

Although the incidence of sciatic nerve palsy following total hip arthroplasty is low, this complication can cause devastating permanent nerve palsy. The authors experienced a case of sciatic nerve palsy caused by ruptured and contracted external rotator muscles following total hip arthroplasty in a patient suffering from osteonecrosis of the femoral head. We report this unusual case of sciatic nerve palsy with a review of the literature.

STUDY DESIGN: A case report. OBJECTIVES: Lumbar burst fracture was treated with operation, which delayed recollapse of L1 and led to conus medullaris syndrome. SUMMARY OF LITERATURE REVIEW: After operation, conus medullaris syndrome causing by delayed recollapse is not frequently reported. MATERIALS AND METHODS: A 56-year-old male was admitted with lower back pain caused by a fall. Radiologic findings showed L1 burst fracture with about 42% of height loss. There was no neurologic deficit. Posterior fusion was performed using instrumentation. Five weeks after the operation, the patient was admitted for urination and defecation difficulty. Radiologic findings showed that the L1 had recollapsed with about 38% of height loss. To resolve the problem, anterior surgery was performed. RESULTS: Two years after surgery, bladder and anal sphincter dysfunction wasn't recovered. CONCLUSIONS: Lumbar burst fracture should be follow up carefully until union of the fracture because burst fracture leads to delayed recollapse.

A 73-year-old male was admitted for unhealed wound. Eight months ago, the patient had been operated for excision of soft tissue mass on left distal thigh area in previous hospital and after 4 months from first operation, had been reoperated because of recurrence. The pathologic diagnosis of previous operation was simple cyst. In operating finding, the mass invaded the vastus lateralis fascia and had irregular margin and adhesion. We carried out simple excision with retaining 5 cm of free margin from the mass. The pathologic diagnosis of our hospital was malignant fibrous histiocytoma, and then the patient was performed radiation therapy. In 1 year follow-up, there was no significant finding either increasing mass size or metastasis. We misdiagnosed as simple cyst and then performed simple excision, however finally pathologic diagnosis confirmed as malignant fibrous histiocytoma. It is considered to operate a mass that preoperative proper evaluation and diagnosis are required.

PURPOSE: The aim of this study was to evaluate the usefulness of a method for positioning the femoral stem in neutral position refer to the measured value of "lateral distance" in pre-operative templating and the femoral stem position post-operatively. MATERIALS AND METHODS: A total of 81 hips in 76 patients underwent cementless total hip arthroplasty between March 2008 and April 2012 using the C2 stem (Lima Corporate S.P.A, Udine, Italy). We measured the perpendicular distance from the lateral outermost part of the greater trochanter to the lateral outermost part of the femoral stem (lateral distance, LD) in pre-operative templating. We aimed to insert the femoral stem in neutral position by comparing LD measured intra-operatively. We evaluated the position of the femoral stem on post-operative plain radiography. We compared the result of post-operative re-measurement of the LD with that of pre-operative measurement. RESULTS: In all of the 81 cases, the femoral stem was inserted in neutral position, defined as the femoral stem position within 3degreesvalgus or varus. The average angle of the inserted femoral stem was 1.20degrees(0.003-2.85degrees). LD measured in preoperative templating was 15.6 mm(10-21.5 mm), and it showed no correlation ratio with LD; LD re-measured post-operatively was 15.9 mm(10.3-23.5 mm) (P=0.781). CONCLUSION: Measuring LD pre-operatively and using the value intra-operatively is an effective method for insertion of the femoral stem in neutral position.

The authors experienced a case of early fracture of an alumina ceramic liner after ceramic-on-ceramic total hip arthroplasty, without any history of trauma. A 47-year-old male visited our center, due to a sudden crunching sound from the right hip at three weeks, after a ceramic-on-ceramic total hip arthroplasty for the osteonecrosis of right femoral head. Plain radiographs revealed multiple radio-opaque fragments around the displaced neck of the femoral stem. There were severely comminuted fracture of the ceramic liner with slight black staining of the surrounding tissue, and even damaged the surface of the ceramic head, on the operative field. The fractured liner and a damaged head were replaced with a new ceramic liner and head, after the removal of the fractured ceramic fragments, as completely as possible. Careful follow up with a caution for early ceramic liner fracture should be required in ceramic-on-ceramic total hip arthroplasty.

STUDY DESIGN: A Case report. OBJECTIVES: We report a case of thoracic intradural extramedullary tumor that has been misdiagnosed as the cerebral infarction. SUMMARY OF LITERATURE REVIEW: Spinal meningioma is one of the common spinal tumors. Clinical symptoms were characteristically progressive myelopathy, rather than radiculopathy. MATERIALS AND METHODS: A 66-year-old female patient who had a history of cerebral infarction admitted as suffering from progressive lower extremities weakness for 6 months. The patient was diagnosed and has been treated as the cerebral infarction at another hospital. However, the patient showed worsening symptoms. In magnetic resonance imaging, an intradural extramedullary space occupying mass compressing the spinal cord, between T8 and T9 level, was shown. By undergoing an operation, resected the mass. In a pathologic report, mass was confirmed to be meningioma. RESULTS: After the operation, symptoms were improved. The patient was able to walk 2 weeks after surgery. CONCLUSIONS: We report the correct diagnosis and a successful surgical treatment of myelopathy, due to thoracic myelopathy that has been misdiagnosed as the cerebral infarction in another hospital.

In the patient who has intradural mass associated with spinal stenosis, if the operation for spinal stenosis is performed alone, the symptom may remain. We report with literature review that we achieved the successful outcome after simultaneous decompression of spinal stenosis and space occupying mass removal in the case of intradural and extradural compression. A 71-year-old female patient suffering from low back pain and radiating pain of both lower extremities admitted. In magnetic resonance imaging, spinal stenosis on L4-5 and spondylolisthesis on L5-S1 compressed dural sac and intradural space occupying mass on L4 level compressed. By posterior approach, decompression and interbody fusion were carried out. Then mass was removed with median durotomy. Pathologic diagnosis was schwannoma and the symptom was improved remarkably.

PURPOSE: We propose to improve the use of Proximal Femoral Nail Anti-rotation in Korea by reporting anatomical measurements of the normal Korean proximal femur. MATERIALS AND METHODS: A total of 230 patients were enrolled who had all experienced a femoral intertrochanteric fracture and undergone the Proximal Femoral Nail Anti-rotation surgical procedure between February 2007 and April 2011. We measured the neck-shaft angle and endosteal width at the isthmus of a normal femur, and the distance between the greater trochanter and the nail tip of the Proximal Femoral Nail Anti-rotation in post-operative plain radiography. We analyzed the average and standard deviations of the measurements. We also investigated correlations with the patient gender. RESULTS: The average neck-shaft angle and endosteal width at the isthmus were 129.7degrees(111.0~138.3degrees) and 14.5 mm (9.7~23.1 mm), respectively. The average protruded nail length was 4.9 mm (1.0~15.0 mm). The femur neck-shaft angle had a correlation ratio with gender (p=0.000). However, the endosteal width at the isthmus level and the protruded nail length had no correlation ratio with gender (p=0.108, 0.573, respectively). CONCLUSION: Until now, in intertrochanteric fracture operations using Proximal Femoral Nail Anti-rotation, the selection of devices has been extremely limited. Through this study we present the average Korean anatomical neck-shaft angle, endosteal width of the femur, and protruding length of the nail tip. We expect that these numerical values can be used in the production of new devices with shorter proximal nails, which would be more appropriates for Koreans.

STUDY DESIGN: Retrospective study. OBJECTIVES: We analyzed to verify clinical result and recurrence of long term follow-up after open lumbar discectomy. SUMMARY OF LITERATURE REVIEW: There are many reports concerning the clinical result of open discectomy. However, long-term result is not frequently reported. MATERIALS AND METHODS: From 1989 to 2000, 289 patients underwent open discectomies. 142 patients who was followed more than 5 years were enrolled in this study. Follow-up rate, clinical outcome were analyzed as gender, age at the operation and operated level. Re-operation rate was analyzed as gender, age at the operation, operated level divided into same level-same side, same level-contralateral side and other level and the time at reoperation. Clinical outcomes were evaluated by Kim and Kim criteria. RESULTS: More than 5 years follow-up rate was 49.1%. Average follow-up period were 99.2 months. Clinically successful result was obtained in 75.4%, and it was not related with gender, age at the operation and operated level. Reoperations were needed in 21 patients(14.8%). Reoperation rate was not related with gender, age at the operation. Same level-same side reherniation were frequent before 6 months after first surgery, but other side and different level were similar more than 2 years after first surgery. CONCLUSIONS: Our clinical result was acceptable(75.4%). Main cause of reoperations before 6 months after first surgery was recurrence at the same level and same side, but cause of reoperation more than 2 years after first surgery were herniation at the other side and different level increased with time.

STUDY DESIGN: A retrospective study OBJECTIVES: Contralateral undercutting laminoplasty via a unilateral laminotomy has been performed instead of bilateral partial laminectomy in lumbar spinal stenosis. This study compared the radiographic and clinical results of undercutting laminoplasty with bilateral partial laminectomy. SUMMARY OF LITERATURE REVIEW: Less invasive surgery has become attractive for minimizing soft tissue injury and reducing the recovery time. MATERIALS AND METHODS: Twenty five patients, who underwent decompressive surgery for lumbar spinal stenosis and were followed-up more than one year, were enrolled in this study. Unilateral undercutting laminoplasty and bilateral partial laminectomy was performed in 13 and 12 cases, respectively. The blood loss was compared and the presence of instability was observed. The increase in dural cross sectional area was measured in the preoperative and postoperative CT scans. In the clinical assessment, the Oswestry disability index (ODI) and visual analogue scale (VAS) to pain was used. RESULTS: The average blood loss per segment was 273 ml and 436 ml in the laminoplasty and laminectomy group. There was no case of instability after surgery but there was a significant difference in the increase in dural cross sectional area between the two groups: 109.7 mm2 and 78.6 mm2 in the laminoplasty and laminectomy group, respectively. The preoperative and final change in the ODI and VAS scores was similar between the two groups. CONCLUSIONS: Unilateral undercutting laminoplasty is a minimally invasive procedure with less blood loss than the conventional technique and is equally effective.
