PURPOSE: This study was to evaluate the clinical results of the treatment of scaphoid nonunions using a pronator quadratus pedicled bone graft. METHODS: Thirteen patients with a scaphoid nonunion were treated with pronator quadratus pedicled bone graft. The average age of the patients was 20.23 years (range: 19-22 years) and the minimum follow-up period was one year. In all patients, bone grafting was performed and screw was fixed by using a volar aspect of distal radius bone graft with pronator quadratus muscle. RESULTS: All 13 patients showed radiographic union with the average union time of 10.8 weeks (range: 9-13 weeks). Flexion, extension, radial deviation and ulnar deviation of wrist joint improved compared to the preoperative condition (p<0.05). Postoperative scapholunate and radiolunate angle improved compared to the preoperative condition (p<0.05). Eleven patients (84.5%) showed excellent or good results according to Herbert and Fisher's score criteria of functional, subjective satisfaction and radiographic result. CONCLUSION: Pronator quadratus pedicled bone grafting can be considered to be easily accessible technique on vascularized bone graft for osteosynthesis of scaphoid nonunions. It is proved to be effective for bone union, increased wrist joint motion.

Calcific tendinitis on gluteus medius tendon of the amateur athletes were reviewed, and a study on the therapeutic effect of conservative treatment methods. From January 2003 to December 2010, among the patients who had been treated with calcific tendinitis on gluteus medius tendon, there were nine patients available to monitor more than a year as outpatients. ten cases were observed from them and were retrospectively analyzed and magnetic resonance examinations were performed in every case. All of the ten cases were initially treated with non-steroid anti-inflammatory oral doses. If a non-steroid anti-inflammatory treatment could not relieve pain or caused an aggravation of a condition, a local steroid injection was enforced. There were responses to non-steroid antiinflammatory oral doses of therapeutic methods in four cases and the time required for the symptoms to be improved was approximately 3 weeks (range: 1-3 weeks). In the remainder of six cases, conditions got worsened or did not improve even after 3 weeks. In these cases, the condition was altered for better in 3 days (range: 1-3 days) by using local steroid injections. There was no recurrence in all cases. The amateur athlete with a severe pain around his or her hip joint should be questioned with calcific tendinitis on gluteus medius tendon and differential diagnosis of hip around diseases. After calcific tendinitis was diagnosed, initial treatment was considered conserevative treatment. Although it is invasive, the initial treatment with a local steroid injection is considered to be helpful in treating amateur athletes with calcific tendinitis.

Hamstring injuries are common forms of muscle strains in athletes but a complete rupture of a proximal hamstring origin is rare. Often there is a considerable delay in diagnosis and stringent treatment because of its rarity, difficulty in clinical diagnosis, and initial attempts of conservative care. We report two cases of acute complete rupture of the proximal hamstring tendons treated with early surgical repair. The diagnosis and treatment of this unusual injury are discussed.

BACKGROUND: Because acute cholecystitis in elderly hip fracture is not easily distinguishable from other gastrointestinal symptoms and involves atypical clinical behaviors, it may not be diagnosed in the early stage. However, the exact incidences could not be reported. We utilized data from a nationwide claims database and attempted to assess the incidence of acute cholecystitis in elderly hip fracture patients and how cholecystitis affects mortality rates after hip fracture. METHODS: Study subjects were from the Korean National Health Insurance Service-Senior cohort. From a population of approximately 5.5 million Korean enrollees > 60 years of age in 2002, a total of 588,147 participants were randomly selected using 10% simple random sampling. The subjects included in this study were those who were over 65 years old and underwent surgery for hip fractures. RESULTS: A total of 15,210 patients were enrolled in the cohort as hip fracture patients. There were 7,888 cases (51.9%) of femoral neck fracture and 7,443 (48.9%) cases of hemiarthroplasty. Thirty-six patients developed acute cholecystitis within 30 days after the index date (30-day cumulative incidence, 0.24%). Four of the 36 acute cholecystitis patients (11.1%) died within 30 days versus 2.92% of patients without acute cholecystitis. In the multivariate-adjusted Poisson regression model, hip fracture patients with incident acute cholecystitis were 4.35 (adjusted risk ratio 4.35; 95% confidence interval, 1.66–11.37; P = 0.003) times more likely to die within 30 days than those without acute cholecystitis. CONCLUSION: Incidence of acute cholecystitis in elderly patients after hip fracture within 30 days after the index date was 0.24%. Acute cholecystitis in elderly hip fracture patients dramatically increases the 30-day mortality rate by 4.35-fold. Therefore, early disease detection and management are crucial for patients.

OBJECTIVE: Sequelae of behavioral impairments associated with human traumatic brain injury (TBI) include neurobehavioral problems. We compared exploratory, cognitive, and depressive-like behaviors in pediatric and adult male mice exposed to controlled cortical impact (CCI).METHODS: Pediatric (21 to 25 days old) and adult (8 to 12 weeks old) male C57Bl/6 mice underwent CCI at a 2-mm depth of deflection. Hematoxylin and eosin staining was performed 3 to 7 days after recovery from CCI, and injury volume was analyzed using ImageJ. Neurobehavioral characterization after CCI was performed using the Barnes maze test (BMT), passive avoidance test, open-field test, light/dark test, tail suspension test, and rotarod test. Acutely and subacutely (3 and 7 days after CCI, respectively), CCI mice showed graded injury compared to sham mice for all analyzed deflection depths.RESULTS: Time-dependent differences in injury volume were noted between 3 and 7 days following 2-mm TBI in adult mice. In the BMT, 2-mm TBI adults showed spatial memory deficits compared to sham adults (P < 0.05). However, no difference in spatial learning and memory was found between sham and 2-mm CCI groups among pediatric mice. The open-field test, light/dark test, and tail suspension test did not reveal differences in anxiety-like behaviors in both age groups.CONCLUSION: Our findings revealed a graded injury response in both age groups. The BMT was an efficient cognitive test for assessing spatial/non-spatial learning following CCI in adult mice; however, spatial learning impairments in pediatric mice could not be assessed.

Perihepatic capsulitis is associated with various diseases, such as Fitz-Hugh-Curtis syndrome, systemic lupus erythematosus, perforated cholecystitis, perforated hepatic abscess, and tuberculous peritonitis. Miliary tuberculosis is present in about 2% of all reported cases of tuberculosis and is characterized by the widespread millet-like hematogenous dissemination of Mycobacterium tuberculosis. We describe a 24-year-old virgin patient presenting with right upper quadrant and costovertebral angle pain. Diffuse perihepatic capsular enhancement was observed in abdominal computed tomography scans. Chest radiography showed miliary tuberculosis, and a polymerase chain reaction hybridization assay of sputum revealed the presence of M. tuberculosis. Symptoms improved after administering anti-tuberculosis medications. This report describes a rare case of miliary tuberculosis accompanying perihepatitis.

PURPOSE: This study examined the difference in the reduction of the amount of required allogenic transfusion after bilateral total knee arthroplasty when an autotransfusion device was used. MATERIALS AND METHODS: The subjects were ninety five patients who underwent sequential bilateral total knee arthroplasty from January 2006 to May 2010 by one surgeon. The first group was 50 patients who did not have an autotransfusion device used and second group of 45 patients were those who had an autotransfusion device used during the postoperative period. Group 1 received allogenic blood transfusion with a standard level of postoperative hemoglobin. The group 2 patients were reinfused with as much blood as was collected by an autotransfusion suction bag and then they received allogenic blood transfusion with a standard level of postoperative hemoglobin. RESULTS: The total blood loss and amount of blood transfusion were almost the same in the two groups. The mean amount of allotransfusion was 1,270.0 mL in group 1 and 564.4 mL in group 2 and the reduced amount of allotransfusion in group 2 was statistically significant (p<0.05). CONCLUSION: Using an autotransfusion device is a good method to reduce the mean amount of allotransfusion after bilateral sequential total knee arthroplasty.

PURPOSE: We believe that cemented femoral stems will relieve the stiffness of ceramic-based bearings, resulting in reduced complication of ceramic-on-ceramic bearing total hip arthroplasty (THA). The purpose of this study was to evaluate the midterm effect of ceramic-on-ceramic bearing THA using cemented femoral stems. MATERIALS AND METHODS: We studied 32cases (30 patients) of THA using ceramic-on-ceramic bearing cemented femoral stems and 33 cases (31 patients) of THA using ceramic-on-ceramic bearing cementless femoral stems. All total hip arthroplasties were performed between January 2004 and December 2005 and were followed up for more than 5 years. The clinical results and radiographic results were evaluated. RESULTS: The mean HHS improved from points pre-operatively to points at the last follow-up in both the cemented and cementless stem groups (P<0.05). The mean WOMAC score also improved from points pre-operatively to points at the last follow-up in both the cemented and cementless stem groups (P<0.05). But no statistically significant difference was noted between the cemented and cementless stem groups in HHS and WOMAC scores (P=0.304, P=0.769). There were 3 patients with a sense of discomfort on ambulation and 5 patients with thigh pain in the cementless stem group and no cases in the cemented stem group. There was no instance of acetabular loosening in either group. Subsidenc of the cemented femoral stem was less than 1mm in 30 cases and less than 2 mm in 2 cases. All cementless femoral stems acquired firm bony union. CONCLUSION: Midterm results showed no statistical links between ceramicon-ceramic-bearing THA using cemented femoral stems or cementless femoral stems.

Cytomegalovirus (CMV) infection is more frequent in immunocompromised patients those with acquired immunodeficiency syndrome (AIDS), malignant disease, steroid therapy. However, CMV can infect a healthy person who has normal immunity. Most cases of CMV infections are due to reactivation of latent virus. We report a case of cytomegalovirus colitis in a 73 years old woman who has congestive heart failure with normal immunity. Sigmidoscopy reveals cobble stone like mucosa and deep ulceration. CMV infection produces a cytomegalic cell containing a intranuclear inclusion, which is surrounded by clear halo in Hematoxylin-Eosin stain. Immunohistochemical stain for CMV reveals focal positive in cytoplasm and in nuclei of large cells. We diagnosed CMV colitis with histopathologic finding and immunohistochemistry through sigmoidoscopic mucosal biopsy.

PURPOSE: The purpose of this study is to determine the results of conservative treatment of osteochondral lesion of talus (OLT). This study would be helpful to determine the treatment methods for OLT patients. MATERIALS AND METHODS: We have established 69 cases of osteochondral lesion of talus, from December 2004 to June 2006 in a period of 18 months. Symptoms were confirmed through survey and a medical examination by interviewing patients. Diagnosis was made through physical examination, simple radiography and MRI. AOFAS score of all the patients were measured. When the patients did not get improved with conservative treatment, surgical operation was done. RESULTS: 27 out of the 69 patients were treated using conservative treatment. Initial AOFAS scored was 66.37+/-8.89 points. After treatment, AOFAS scores had increased to 83.78+/-8.48 points. In cases of surgery, AOFAS scores had increased from 64.17+/-13.43 points preoperatively to 80.45+/-8.67 points. CONCLUSION: 60% of conservative treatment was useless in treating OLT patients. Surgical operation is still needed to be performed. Therefore, treatment should be done with sufficient understanding of the results.
