Ventriculoperitoneal shunting is the most common neurosurgical procedure for treatment of hydrocephalus. Shunt-related complications are relatively common and associated with a high rate of shunt revision. However, migration of the distal ventriculoperitoneal shunt, especially into the cardiac and intravascular regions, has rarely been reported. Awareness of this rare but potentially hazardous complication is important owing to its significant morbidity, which can be prevented by prompt management. Here, we introduce a case of a 23-year-old male with migration of the distal shunt catheter through the left internal jugular vein into the cardiac chamber and both pulmonary arteries, which occurred 2 months after receiving ventriculoperitoneal shunting. Furthermore, we discuss the possible mechanisms and management of this condition.

The purpose of this study was to evaluate the effects of convergence-based reeducation of core basic nursing skills (subcutaneous injection, indwelling catheterization) on competence, knowledge, attitude and confidence for nursing students. Subjects were 34 nursing students and 3rd grade. Experimental treatment and data collection was conducted from December 14 to 29, 2013. Skills for subcutaneous injection including simple blood glucose test and indwelling catheterization were evaluated before and after intervention. Knowledge, attitude and confidence were measured using structured questionnaires. Data were analyzed by the frequency, descriptive statistics and paired t-test using SPSS version 21. As a result, after reeducation, significant improvement was found in competence (p<.001), knowledge (p<.001) and confidence (p<.001) in subcutaneous injection and indwelling catheterization. Convergence-Based reeducation program was found effective to enhance the competence of core basic nursing skills before graduating nursing students. Therefore, it is necessary to continue to develop program and to evaluate the effects with further research.

Purpose : Preliminary report of the technique and trial of double bundle PCL reconstruction using Achilles allograft. Materials and Methods : From May 1999 to July 2000, 8 cases of PCL insufficient patients were treated with Achilles allograft reconstruction using the double bundle and double femoral tunnel technique. The tibial tunnel was prepared anteromedially. All other combined injuries within the knees were treated accordingly. Minimal follow-up period was 1 year. The results was assessed from the point of function and stability using Lysholm knee score and KT-2000 arthrometer. Results : Up to present follow up. 8 patients showed good sign of recovery with no instability (translation less than 2 mm) except olio that has been grafted-ligament rupture. In addition, none showed any sign of infection nor ROM limitation. Two complications were seen, which one had grafted-bone fracture and the other grafted-ligament rupture. The former occurred during operation and the latter occurred due to improper protection. Conclusion : Presently the follow up period is too short to draw any conclusive opinion but it is essential to select healthy and well sterilized allografts fur successful outcome. Double femoral tunnel technique seems to be more physiologic in PCL reconstruction. With these prerequisites, it seems to be a good alternative to use Achilles allografts fur the reconstruction of PCL. However, a longer follow-up is needed.

Purpose : The purpose was to assess the result of arthroscopic management of the septic arthritis on the knee in compromised patients. Materials and Methods : Fourteen patients with septic knee were analyzed. The mean age was 55 years and the mean follow-up period was 14.6 months. Underlying diseases included 4 cases of diabetes, and history of direct acupuncture in 4 cases. Clinical stage of septic arthritis was judged by $G\ddot{a}chter's$ classification, which was determined by arthroscopic findings. After arthroscopic irrigation and debridement, we observed the results of laboratory data and improvement of clinical findings. Results : Causative organism was identified in 7 cases and no organism was detected in the remaining 7 cases. Stage I was 1, stage II 8, stage III 4, and stage IV 1, respectively. Eleven of 14 cases were improved by one stage operation. Two cases of stage III were recurred and additional arthroscopic management was done. In 1 case of stage IV, symptom was not improved and needed arthrotomy. The result was unsatisfactory in patients with stage III and IV. Serum erythrocyte sedimentation rate and C-reactive protein were normalized after 29.3 and 20.8 days following the operation, respectively. Clinical symptoms disappeared average 2 days following the operation. Conclusion : Arthroscopic management of acute septic arthritis of the knee would be an effective and satisfactory treatment modality in that its postoperative pain and complications are minimal, and it can be done with ease repeatedly.

This study aimed to analyze the changes of C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) measured in acute infection within four weeks post artificial joint surgery to predict potential infection in early stages, provide rapid treatment, and prevent the abuse of antibiotics. This study included 50 patients with acute infection and 50 patients without any symptoms of infection, among patients who received artificial joint replacement surgery on the lower limbs in a four-week period. CRP was the highest two-to-three days after surgery. with $5.77{\pm}3.69$ and $5.17{\pm}3.48$, respectively, in those with infection and without infection. Thereafter, the value rapidly reduced in those without infection. However, it increased again to $3.16{\pm}2.87$ in the group with infection according to the bimodal curve (p<0.001). ESR was the highest two-to-three days after surgery, with $58.8{\pm}24.63$ and $44.08{\pm}21.48$, respectively. Thereafter, the value slowly reduced in those without infection. However, it was increased again to $47.62{\pm}26.26$ in those with infection according to the bimodal curve p<0.001). As this study shows, if there is an increasing trend for CRP and ESR after artificial joint replacement surgery, it may be possible to question whether patients are acutely infected post surgery. In particular, this result is expected and regarded as a useful factor for diagnosing infection due to the high level of sensitivity and uniqueness for CRP.

Purpose : We report a result of arthroscopic treatment of the recurrent prepatellar bursitis. Materials and Methods : Between March 2001 and May 2002, we treated 4 patients with prepatellar bursitis, the average follow-up period was 14.5 months. The causes were acute trauma 3 cases and repeated minor trauma 1 case. All cases were recurred after previous history of the conservative therapy at other hospital but one was a recurred case after operative excision. Operative technique was as follows. Before inserting the arthroscope, the bursa was inflated with saline. The portals fur 4 mm diameter arthroscope were placed 1cm away from the bursal sac through small skin incision. Superficial layer of the bursa was resected first and then deep portion was the next. Several percutaneous mattress sutures were applied to the overlying skin with deep tissue, and compressive dressing was applied and maintained for 2 weeks. Results : All 4 cases were no recurrence, no pain, no tenderness. The results were considered satisfactory, Two cases of mild skin dimpling at suture site were observed. Conclusion : Arthroscopic treatment of the prepatellar bursitis is an another method of operation technique fur recurrent prepatellar bursitis, however long term follow-up will be needed about recurrence.

Purpose : After the total or partial meniscectomy of the lateral discoid meniscus, many patients complain the residual pain or the recurrent symptoms of the meniscus, and some of them need reoperation. We analyzed the causes of the reoperation after initial meniscectomy. Material & Method : Two hundred seventy three patients with the symptomatic lateral discoid meniscus were treated by arthroscopic meniscectomy between October, 1989 and September, 1998. Of the 273 patients, 69 patients were treated by total meniscectomy and 204 patients were treated by partial meniscectomy. The male to female sex ratio was 1:1.04, and the average of the age was 23.1 years old(from 4 to 59 years old). The reoperation was done in 8 patients, of which 1 was the case of total meniscectomy at the initial operation, and the rest 7 were the case of partial meniscectomy. Results : Of the 8 reoperations, 3 patients recurred the meniscal symptoms within the 3rd week after the initial operation, and 5 patients recurred beyond the 3rd week after the initial operation. Among the 3 patients of carly recurrence, 2 patients showed inadequate sizes of the remnant meniscus, and 1 patient showed posterolateral instability of the remained meniscus. Among the 5 patients of late recurrence, 3 patients showed rerupture of the meniscus, and 2 patients showed associated pathology of degenerative arthritis following osteochondritis dissecans. Conclusions : The reoperation rate after initial meniscectomy of the lateral discoid meniscus was higher in partial meniscectomy than total meniscectomy. During the operation of the lateral discoid meniscus, we must determine the adequate resectional margin, confirm the remnant meniscus by probing, and look for the associated pathologies.

Purpose: The clinical outcomes were investigated to determine if arthroscopic management is a useful method for 19 hips with iliopsoas tendon impingement (IPI) after total hip arthroplasty (THA). Materials and Methods: Eighteen patients (19 hips), who complained of groin pain and flexion pain that persisted after THA from September 2013 to December 2019, were the subjects of this investigation. The mean time to manifestation after THA was four months (range, 1-9 months) in patients of an average age of 60 years (range, 50-69 years). Thirteen out of 18 patients underwent THA using the direct anterior approach and five by the lateral approach. IPI was diagnosed by the medical history, physical examination, blood test, radiographic examination using X-ray and computed tomography, and topical injection therapy. All patients underwent arthroscopic treatment and a dynamic arthroscopic physical examination after exposure to the iliopsoas tendon revealed impingement. Tenotomy was then performed on the muscle portion through the total tendon portion. Symptoms and pain levels of preoperative, postoperative and follow-up period were investigated and compared. Results: The Western Ontario and McMaster Universities Osteoarthritis Index score decreased from an average of 58.4 (range, 40-88) before surgery to an average of 35.0 (range, 15-76) after surgery. Similarly, the visual analogue scale decreased from an average of 4.0 (range, 2-6) before surgery to an average of 1.4 (range, 0-4) after surgery. Sixteen patients (88.9%) showed pain relief and improvement in the straight leg raise test, and two patients showed postoperative muscle weakness and sustained pain. In the follow-up period, muscle weakness improved. One patient underwent arthroscopic iliopsoas tenotomy at the lesser trochanteric level but the symptoms persisted. The clinical symptoms were improved after one more tenotomy at the joint level. Conclusion: Arthroscopic iliopsoas tenotomy performed in patients with IPI after THA showed good clinical results.

Purpose: Metacarpal fractures are common injuries of the hand. They are treated using closed reduction (CR) or open reduction (OR) techniques. The management strategy depends on fracture site characteristic and fixation methods. In this study, we evaluated pre- and postoperative fracture angulation, when metacarpal fractures bad been treated using two different techniques: CR with parallel transverse pinning and OR with plate fixation. Methods: Forty-six patients undergoing anatomic reduction to treat extra-articular metacarpal fractures were recruited. They were included in one of two therapeutic groups: Group 1, CR with parallel transverse pinning (n=21); Group 2, OR with plate fixation (n=25). Fracture angulation values have been measured on pre- and postoperative radiologic images. Values were compared between pre- and postoperative states, and between corresponding measurements of each group. Results: All extra-articular metacarpal fractures were successfully treated without wound related complications or the limit of joint motion. Both groups demonstrated adequate reduction at immediate postoperative period (postoperative angulation of group 1, $20^{\circ}{\pm}7^{\circ}$; group 2, $19^{\circ}{\pm}5^{\circ}$). During the observation at follow-up period, Group 1 exhibited slight recurrence (follow-up angulation of group 1, $24^{\circ}{\pm}10^{\circ}$). Nonetheless, Group 2 showed adequate reduction state in both immediate postoperative and long-term follow-up periods (follow-up angulation of group 2, $18^{\circ}{\pm}6^{\circ}$). Conclusion: Extra-articular metacarpal fractures were successfully restored without functional complications. CR with parallel transverse pinning method exhibited recurrence after pin removal, which necessitates cautious postoperative exercise and monitoring.
