Minimally Invasive Percutaneous Plate Osteosynthesis via a Deltoidsplitting Approach with Strut Allograft for the Treatment of Displaced 3- or 4-part Proximal Humeral Fractures

BACKGROUND: This study introduces a surgical technique with good clinical outcome useful in the treatment of osteoporotic displaced 3- or 4-part proximal humeral fractures. METHODS: From May 2014 to February 2016, 16 patients with displaced 3- or 4-part proximal humeral fractures were treated by application of a locking plate with an endosteal strut allograft via a deltoid splitting approach with a minimum follow-up of 12 months. The allograft was inserted through a fractured gap of the greater tuberosity to support the humeral head and then fixed by a locking plate with meticulous soft tissue dissection to protect the axillary nerve. Surgical outcomes were evaluated by the American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) scores, radiological imaging, and clinical examination. Fixation failure on radiographs was defined as a >5° loss of neck shaft angle (NSA) compared to that on an immediate postoperative radiograph. Avascular necrosis (AVN) of the humeral head was also evaluated. RESULTS: In all cases, complete union was achieved. The ASES and VAS scores were improved to 85.4 ± 2.1 and 3.2 ± 1.3, respectively. Twelve patients (75.0%) had greater than a 5° change in NSA; the average NSA change was 3.8°. Five patients (31.3%) had unsatisfactory ranges of motion exhibiting a < 100° active forward flexion. No axillary nerve injuries or AVN were observed at the last follow-up. One patient was converted to reverse total arthroplasty due to severe pain and functional deficit. CONCLUSIONS: Minimally invasive fixation via a locking compression plate and an endosteal fibula strut allograft in Neer classification 3-or 4-part fractures with severe osteoporosis in elderly patients can achieve good clinical results.

Coil embolization of ruptured intrahepatic pseudoaneurysm through percutaneous transhepatic biliary drainage / 영남의대학술지

A 75-year-old man with chronic cholangitis and a common bile duct stone that was not previously identified was admitted for right upper quadrant pain. Acute cholecystitis with cholangitis was suspected on abdominal computed tomography (CT); therefore, endoscopic retrograde cholangiopancreatography with endonasal biliary drainage was performed. On admission day 5, hemobilia with rupture of two intrahepatic artery pseudoaneurysms was observed on follow-up abdominal CT. Coil embolization of the pseudoaneurysms was conducted using percutaneous transhepatic biliary drainage. After several days, intrahepatic artery pseudoaneurysm rupture recurred and coil embolization through a percutaneous transhepatic biliary drainage tract was conducted after failure of embolization via the hepatic artery due to previous coiling. After the second coil embolization, a common bile duct stone was removed, and the patient presented no complications during 4 months of follow-up. We report a case of intrahepatic artery pseudoaneurysm rupture without prior history of intervention involving the hepatobiliary system that was successfully managed using coil embolization through percutaneous transhepatic biliary drainage.

The Effect of Screw Apophysiodesis of Greater Trochanter in Legg-Calve-Perthes Disease / 대한정형외과학회잡지

PURPOSE: To evaluate the interstitial and appositional growth of greater trochanter post-screw apophysiodesis in Legg-Calve-Perthes (LCP) disease. MATERIALS AND METHODS: A total of 17 patients, who were diagnosed with LCP and underwent greater trochanter screw apophysiodesis and metal removal between December 2003 and December 2012, and were followed-up for at least 4 years, were selected. Anterioposterior radiologic images were taken in each process of apophysiodesis, metal removal, and last follow-up. From such images, articulotrochanter tip distance (ATD), trochanter tip-screw distance (TSD), trochanter tip-trochanter lower margin distance (TLD), and screw-trochanter lower margin distance (SLD) were measured. Appositional growth and greater trochanter growth rates were compared using paired t-test, independent t-test, and correlation analysis. RESULTS: The average ATD of the affected and unaffected sides was 14.2 and 16.8 mm, respectively at apophysiodesis and 9.2 and 14.8 mm at the last follow-up, with a significantly greater decrease observed on the affected side the unaffected side (p=0.030). TLD of the affected side during the follow-up increased 11.0 mm, from an average of 30.8 to 41.8 mm, while the un-affected side increased 14.3 mm, from an average of 26.7 to 41.0 mm. The growth of greater trochanter after the operation in the affected side was 76.7% of that in unaffected side. The ratio of TLD of the affected side to the unaffected side was significantly reduced, from 1.15 to 1.02 (p=0.014) at the final follow-up. TSD was significantly increased from 4.5 to 14.4 mm at metal removal (p < 0.001) and increased to 17.0 mm at the last follow-up. Moreover, the ratio of TSD to SLD was significantly increased from 0.20 to 0.74 at metal removal (p < 0.001) and increased to 0.84 at the final follow-up. CONCLUSION: The results of this study showed that screw apophysiodesis can suppress the overall growth, but not the appositional growth of the greater trochanter. Therefore, screw apophysiodesis may not be a good procedure to inhibit the growth of greater trochanter.

The Relationship between Superior Disc-Endplate Complex Injury and Correction Loss in Young Adult Patients with Thoracolumbar Stable Burst Fracture

BACKGROUND: To determine the relationship between superior disc-endplate complex injury and correction loss after surgery in a group of young adult patients with a stable thoracolumbar burst fracture. METHODS: The study group was comprised of young adult patients who had undergone short-segment posterior fixation and bone grafting under the diagnosis of a stable thoracolumbar burst fracture from March 2008 to February 2014. Follow-up was available for more than 1 year. Before surgery, magnetic resonance imaging was performed to determine injury to the anterior longitudinal ligament, posterior longitudinal ligament, and superior and inferior intervertebral discs and endplates. Correction loss was evaluated by the Cobb angle, intervertebral disc height, upper intervertebral disc angle, vertebral wedge angle, and vertebral body height. RESULTS: No significant relation was noted between correction loss and an injury to the anterior longitudinal ligament, posterior longitudinal ligament, inferior intervertebral disc/endplate, and fracture site, whereas an injury to the superior endplate alone and superior disc-endplate complex showed a significant association. Specifically, a superior intervertebral disc-endplate complex injury showed statistically significant relation to postoperative changes in Cobb angle (p = 0.026) and vertebral wedge angle (p = 0.047). CONCLUSIONS: A superior intervertebral disc-endplate complex injury may have an influence on the prognosis after short-segment fixation in young adult patients with a stable thoracolumbar burst fracture.

Gastrointestinal Stromal Tumor of the Stomach Presenting as a Perigastric Abscess

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. A 77-year-old man was referred for the evaluation of general weakness and leukocytosis. Computed tomography showed a 9.5×6.5-cm cavitary lesion with an air-fluid level near the stomach, which was thought to be a perigastric abscess. Upper endoscopy revealed a fistula on the greater curvature at the mid body of the stomach. The margin of the fistula opening was clearly demarcated, and yellow turbid fluid oozing from the fistula was seen. Laparoscopic wedge resection was performed at the perforated area of the stomach. Immunohistochemistry revealed CD117 expression. A diagnosis of intermediate-risk GIST was made. No recurrence was identified within 18 months after the operation. The final diagnosis was perforated gastric GIST communicating with the gastric lumen and presenting as an intra-abdominal abscess.

Recurred Macrodystrophia Lipomatosa of the Foot: A Case Report / 대한족부족관절학회지

We reported on a rare case of recurred macrodystrophia lipomatosa of the foot, and reviewed the literature. A 62-year-old male patient presented with right foot second toe pain; preoperative magnetic resonance imaging and radiograph examination was performed. After surgery the biopsy confirmed the diagnosis. American Orthopaedic Foot and Ankle Society score was checked before and after surgery. Wide excision of the affected area including ray amputation is an effective way to prevent recurrence and relieve the pain after surgery. The 2nd toe ray amputation was performed in the treatment of recurred macrodystrophia lipomatosa of the foot, and is thought to be an effective way to relieve pain and prevent recurrence. After minimally invasive surgery with complete excision surgery, additional data on recurrence and pain relief rate are needed.

Hemodynamic Analysis in Patients Who Underwent Lumbar Spine Fusion Surgery without Blood Transfusion / 대한정형외과학회잡지

PURPOSE: Lumbar fusion surgery was performed on transfusion-free patients and hemodynamic changes were analyzed. MATERIALS AND METHODS: A total of 36 transfusion-free patients who had undergone lumbar fusion surgery using recombinant human erythropoietin (rHuEPO) before surgery from April 2007 to March 2014 were included in the study. Hemoglobin and hematocrit levels were measured before surgery, immediately after surgery, 12 hours after surgery, on day 1, day 2, day 3, and day 7. Changes in levels were investigated and the factors affecting the changes in hemoglobin levels were analyzed. RESULTS: Changes in hemoglobin and hematocrit were -18.11% before surgery and -22.92% on day 7, respectively, and they tended to recover from day 2 after surgery. Depending on the patient's age, gender, body mass index, blood loss, and surgery method (presence of lumbar interbody fusion), the changes in hemoglobin level did not show statistically significant differences; however, significant differences were observed in the surgical time and extent of the operation. CONCLUSION: Transfusion alternatives during lumbar spinal fusion are deemed safe methods, leading to good, postoperative hemodynamic outcomes. However, the surgical time and extent of the operation must be determined before surgery.

Clinical Improvement of Severe Reflux Esophagitis in Korea: Follow-up Observation by Endoscopy

BACKGROUND/AIMS: The natural history of severe erosive reflux disease in Korea remains uncertain. We aimed to evaluate endoscopic follow-up results in subjects with severe reflux esophagitis under routine clinical care. MATERIALS AND METHODS: A total 61,891 subjects underwent an upper endoscopic examination in the health check-up program from January 2007 to December 2013. We reviewed medical charts of patients who had been diagnosed with severe reflux esophagitis. The severity of reflux esophagitis was determined by the Los Angeles (LA) classification system. Patients underwent at least one follow up endoscopy after diagnosis of severe reflux esophagitis. We classified the patients into two groups; regressed in severity and remained unchanged, according to follow up endoscopic status. RESULTS: Based on endoscopic findings, 5,938 subjects (9.6%) were found to have reflux esopohagitis: 121 subjects (0.2%) in LA-C; 39 subjects (0.06%) in LA-D. Among 31 patients who had endoscopic follow-up, 23 patients (74.2%) showed regression from LA C/D to LA A/B or minimal change disease or normal. The mean follow up duration was 42.2 months in regression group and 53.2 months in no change group. All patients had been treated with proton pump inhibitors (PPIs) on a regular or on-demand basis. Age, sex, smoking, alcohol, exercise, hypertension, diabetes mellitus, dyslipidemia, sliding hiatal hernia, body mass index, waist circumference and duration of PPIs therapy did not significantly influence regression of severe reflux esophagitis. CONCLUSIONS: The majority of severe reflux esophagitis patients under routine clinical care showed improvement on endoscopic follow-up.

The Relationship of Minor Trauma with the Surgical Outcome in Patients with Cervical Myelopathy

STUDY DESIGN: Retrospective study. OBJECTIVES: To determine the influence of trauma on the neurologic course in patients who have undergone surgery for cervical myelopathy. SUMMARY OF LITERATURE REVIEW: The postsurgical outcomes were worse from trauma in patients who had a cervical ossification of the posterior longitudinal ligament (OPLL) or cervical canal stenosis, in comparison with patients who did not. MATERIALS AND METHODS: The study was conducted on 70 patients who had undergone surgery due to cervical myelopathy from January 2004 to December 2013 and had at least 1 year of follow-up. Depending on trauma history, the patients were divided into two groups, and their radiological (simple radiographic, computed tomographic, and magnetic resonance imaging) and clinical (Japanese Orthopaedic Association [JOA] score, motor power of upper extremities) results were compared retrospectively. RESULTS: Among 70 patients in total, 18 patients were in the trauma group and 52 were in the non-trauma group, and all cases in the trauma group had a history of minor trauma (11 cases of drivers traffic accidents, 4 cases of slipping and falling, 2 cases of minor pedestrian accidents, and 1 case of falling). Radiologically narrower diameter of the spinal canal showed statistically significant difference between two groups (p=0.042). The JOA scores before and after surgery and the recovery rate did not have a clinically meaningful difference with trauma. However, the degree of motor improvement was significantly higher for the trauma group within 1 week after surgery (p=0.040). CONCLUSIONS: Minor trauma itself may adversely affect the patients' clinical courses.

The Surgical Outcome of Tibiotalocalcaneal Arthrodesis Using a Retrograde Intramedullary Nail / 대한족부족관절학회지

PURPOSE: Tibiotalocalcaneal arthrodesis has been used as a treatment option for severe deformity including Charcot arthropathy, avascular necrosis of the talus, and severe osteoarthritis of the ankle and subtalar joint. The purpose of this study was to evaluate the result of the surgical outcome of tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail. MATERIALS AND METHODS: Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail was performed by one surgeon in 36 cases. Clinical and radiological finding was evaluated using assessment of fusion time, 5th metatarsal-tibial angle, possibility of postoperative complication, visual analogue scale for pain and American Orthopaedic Foot and Ankle Society (AOFAS) score. RESULTS: Union was achieved in 33 cases at an average of 23 weeks (11~29 weeks). There were 3 cases of nonunion and 1 case of reoperation. Nail-tibial angle tended to be larger in nonunion cases. AOFAS score showed significantly poor outcome at malalignment (> or =5degrees), negative value of 5th metatarsal-tibial angle. CONCLUSION: Tibiotalocalcaneal arthrodesis using a retrograde intramedullary nail is considered a useful treatment option for severe destruction and deformity involving ankle and subtalar joint.

A Case of Recurrent Glucocorticoid-Induced Pheochromocytoma Crisisb during the Treatment of Urticaria / 대한내과학회지

Pheochromocytoma crisis is a life-threatening endocrine emergency. Stimuli that can elicit a pheochromocytoma crisis include anesthesia, tumor manipulation, and several drugs. Rarely, glucocorticoids can induce a pheochromocytoma crisis. Here, we describe the case of a 65-year-old female who developed an adrenergic crisis with blood pressure fluctuations, dizziness, and seizures after receiving glucocorticoids for the treatment of urticaria. The symptoms led us to speculate that a pheochromocytoma was present. We confirmed the diagnosis based on abdominal imaging and biochemical studies. The patient's symptoms improved after surgical removal of the pheochromocytoma.

Clinical study of the skeletal Cl III malocclusion patients after 2-phase surgical-orthodontic treatment

The purpose of this study was to evaluate the result after 2-phase surgical-orthodontic treatment without preoperative orthodontic treatment for the skeletal Cl III malocclusion patient and to obtain an adequate protocol on the bases of this result. This retrospective study of ten patients who underwent 2-phase treatment were done to evaluate 1) the surgical stability and relapse pattern 2) the facial esthetics 3) the TMJ problem 4) the total time of the treatment. Results were followed : 1) The horizontal relapse of the mandible was 26.8% and didn't show significant differences compared to the conventional 3-phase treatment. But, it was considered that this amount of relapse was the sum of true relapse and autoratation of mandible due to decreased vertical dimension during orthodontic treatment. 2) It was estimated that there's no difference on the ratio of anterior facial height between the subjects and the normal patients. On the horizontal analysis, the mandible of the subjects was located more anteriorly than that of the normal patients. This result showed that there was a need for the accurate preoperative esthetic evaluation and the additional methods for reducing the relapse due to the occlusal interference. 3) Wide variation was noted on the TMJ symptoms of the subjects, however, it was estimated that there's no significant differencees of symptoms compared to that of the conventional 3-phase treatment on literatures. 4) The average of the overall period of treatment was 20.8 months and we obtained reduction of the treatment time compaired to 3-phase treatment on many literatures. Most of the results of this study were similar to the findings of the 3-phase treatment(preoperative orthodontic-orthognathic surgery-postoperative orthodontic), but total time of the treatment was shorter in patients with 2-phase treatment than in those with the conventional 3-phase treatment. With 2-phase treatment, we experienced many advantages compared to the conventional method considering that it was favarable conditions for the teeth, it had the flexibility for the treatment, and it could be the adequate treatment approach for the stomatognathic system. Although this retrospective pilot study had some limitations, due to small samples, the authors would hope that it could serve as a guide for the future reaearches, and the clinical applications.
