We report the case of a polyethylene tibial post fracture in a 72-year-old woman 14 months after a Scorpio posterior-stabilized (PS) total knee arthroplasty. The polyethylene wear was found around the fracture site of the post, especially over the anterior aspect of the post base. The failure mechanism of the post fracture in the present case was anterior impingement with excessive wear over the base of the anterior aspect of the tibial post, which became a stress-riser of post and cam articulation. This is the first report of a polyethylene tibial post fracture of a Scorpio PS prosthesis.

Glycogen storage disease type Ia (GSD-Ia) is an autosomal recessive disorder that has defects in glucose-6-phosphatase (G6Pase) in liver, kidney and intestinal mucosa. The defect leads to inadequate conversion of glucose-6-phospate to glucose in the liver and thus makes affected individuals susceptible to fasting hypoglycemia, hyperuricemia, lactic acidemia and hyperlipidemia. Hyperuricemia has been observed in a considerable number of patients and in some of those, clinical gout has occurred. Inhibited tubular secretion of uric acid due to hyperlacticacidemia and ketonemia, and overproduction of uric acid have been postulated as a mechanism for hyperuricemia in patients with GSD-Ia. A 30-year-old male was admitted with fatigue, foot pain and multiple gouty tophi on knee, ankle, and elbow. GSD-Ia and gout were confirmed by analysis of the G6Pase gene and tophi aspiration respectively. He was treated with allopurinol and uncooked cornstarch. After treatment, foot pain improved and the number and size of tophi were decreased.

PURPOSE: To study the correlation between the outcome of the early postoperative period and the long-term outcome after surgery for partially accommodative esotropia. METHODS: The medical records of total 85 patients with partially accommodative esotropia, who underwent bilateral medial rectus muscle recession, and were followed-up at least 6 months, were retrospectively reviewed. The results were analyzed at 1 month, and 1 and 4 years after surgery. RESULTS: Of the 85 patients, 67 (78.8%) revealed postoperative deviation of less than 10 PD, 11 (12.9%) and 7 (8.2%) esotropia and exotropia more than 11 PD, respecrively, 1 month after surgery. At 1year postoperatively, 59 (77.6%), 8 (10.5%) and 9 (11.8%) showed acceptable deviation, undercorrection, and overcorrection, respectively. 4 years after surgery, 26 (81.2%) and 3 (9.4%) each showed acceptable deviation, undercorrection, and overcorrection, respectively. The results showed a tendency to become exotropic during the 4 years after surgery. CONCLUSIONS: In partially accommodative esotropia, it is essential that orthotropia or minimal esotropia should be present in the early postoperative period in order to obtain a good binocular alignment as the long term result. It is recommended that overcorrection be avoided in early postoperative exotropia.

Traditional adipose tissue transplantation has unpredictable viability and poor absorption rates. Recent studies have reported that treatment with platelet-rich plasma (PRP), adipose-derived stem cells (ASCs), and stromal vascular fraction (SVF) are related to increased survival of grafted adipose tissue. This study was the first simultaneous comparison of graft survival in combination with PRP, ASCs, and SVF. Adipose tissues were mixed with each other, injected subcutaneously into the back of nude mice, and evaluated at 4, 8, and 12 weeks. Human adipocytes were grossly maintained in the ASCs and SVF mixtures. Survival of the adipose tissues with PRP was observed at 4 weeks and with SVF at 8 and 12 weeks. At 12 weeks, volume reduction in the ASCs and SVF mixtures were 36.9% and 32.1%, respectively, which were significantly different from that of the control group without adjuvant treatment, 51.0%. Neovascular structures were rarely observed in any of the groups. Our results suggest that the technique of adding ASCs or SVF to transplanted adipose tissue might be more effective than the conventional grafting method. An autologous adipose tissue graft in combination with ASCs or SVF may potentially contribute to stabilization of engraftment.

A pressure sore, such as quadriplegia, is developed in patients who have been idle in bed for a long time, particularly in the spinal cord. The treatment is particularly difficult in cases of multiple recurrent sores, osteomyelitis with pathologic fractures, other underlying conditions such as diabetes mellitus, immuno-suppression, or radiotherapy. Over the last 20 years, the development and popularization of rectus abdominis flap have significantly increased for reconstruction of a wide variety of difficult clinical problems. From March 2000 to Dec 2001, 6 neurologically impaired patients underwent reconstruction of chronic pressure sores utilizing an inferiorly based rectus abdominis musculocutaneous flap. Postoperative follow-up ranged from 6 to 15 months. The average thickness of rectus abdominis muscle in quadriplegic patient is less than half of that in healthy patient. In most cases, mild venous congestions are developed, but these were resolved by medical treatment. All wounds have healed without any significant complications such as flap loss, infection, hernia, and sepsis. In conclusion, rectus abdominis muscle for these reconstructions provides a simple, reliable solution to often difficult reconstructive problem. We recommended this highly viable, versatile and reliable flap as one to be considered in planning the reconstruction of the quadriplegia patient with pressure sores when other local and regional flaps are unavailable.

PURPOSE: Chest compression is the corner stone of resuscitation. As a result, many studies insist on the importance of retention of skill performance. But there are weak points. First, a unique characteristic of skill is ignored, "the more practice, the better outcome". Second, no one knows when they have a proficiency in a skill. Learning curve-CUSUM analysis is a good tool to evaluate each trainee's performance. Hence, we designed this study to evaluate each trainee's proficiency in performing chest compression using LC-CUSUM analysis. METHODS: Four medical students were enrolled. We asked them to perform chest compression for two minutes per day without any intervention over six weeks. Data included the depth and rate of chest compression. Eventually, all trainees performed chest compression at least 30 times. We plotted the LC-CUSUM curve according to the results of attempts, successes or failures. RESULTS: According to median values of the depth and rate of chest compression through the 30th attempt, trainees had performances within the acceptable range, 40~49 mm (for depth) and 100~105 beats per minutes (for rate) of chest compression. Nonetheless, LC-CUSUM analysis indicated that two trainees no longer were proficient throughout, and even though the rest of them were once proficient, they appear to have lost that proficiency regarding depth of chest compression. LC-CUSUM analysis of rate of compression showed that all trainees had proficiency during the early phase. CONCLUSION: We propose that instructors can evaluate their trainees' proficiency easily, based on LC-CUSUM analysis.

PURPOSE: To report on the complications of hook-plate fixation for distal clavicle fractures. MATERIALS AND METHODS: Eighteen patients who underwent surgery for distal clavicle fracture with a hook-plate from April 2008 to April 2011 were enrolled with a minimum of 4 months follow-up. The reduction was qualified and evaluated according to the radiologic findings. We analyzed the results by UCLA score, Kona's functional evaluation, and VAS pain score. RESULTS: By radiologic evaluation, 17 of 18 cases showed anatomical reduction and solid unions. Although satisfactory results were found in the clinical study as shown by the UCLA score, Kona's functional evaluation, and VAS pain score, complications arose in 7 cases, including osteolysis of the acromion in 2 cases, nonunion in 1 case, periprosthetic fracture in 2 cases, subacromial pain in 1 case, and skin irritation in 1 case. 2 cases of all required reoperation. CONCLUSION: To reduce the complications of the hook-plate, a precise surgical technique and the choice of an appropriate size for the hook-plate are needed. We suggest that early removal of the plate is necessary to decrease the risk of subacromial impingement and erosion in hook-plate fixation.

OBJECTIVES: This study compared attitudes toward antipsychotic treatment according to awareness of the name of their illness in patients with schizophrenia. METHODS: Information on sociodemographic and clinical characteristics, including awareness of the importance of antipsychotic treatment, was obtained through a self-report questionnaire. The Drug Attitude Inventory (DAI) was administered. The data were compared according to awareness of the name of their illness. RESULTS: The study analyzed data for 199 patients with schizophrenia. Of these, 115 patients (57.8%) were aware that their illness was called schizophrenia, while 84 patients (42.2%) knew it by their psychotic symptoms or as another mental illness, such as depression. The patients aware of the name of their illness had significantly longer durations of illness and higher scores on the DAI. They were significantly more likely to have stopped taking medication on their own accord and to agree with the importance of antipsychotic treatment. Statistical significance was sustained in a logistic regression analysis after adjusting for the duration of illness and study site, except for the DAI score, which had borderline significance (p=0.055). In subjects with duration of illness > or =5 years, patients aware of the name of their illness had significantly higher scores on the DAI. CONCLUSION: Awareness of the name of their illness was associated with awareness of the importance of, and a positive attitude toward, antipsychotic treatments in patients. Psycho-education, including telling the patient the correct name of his or her illness, might be needed for maintaining antipsychotic treatment in patients with chronic schizophrenia.

PURPOSE: The objective of this study was to determine the patterns of C-reactive protein (CRP) changes during the postoperative period after total knee replacement (TKR), and to determine the CRP changes associated with infection after TKR. MATERIALS AND METHODS: A retrospective analysis of the pattern of CRP changes during the first 6 postoperative months was conducted on 2,315 patients who underwent unilateral or simultaneous bilateral TKR. This data was also compared with the pattern of CRP changes which occurred in 19 patients with a deep prosthesis infection who were not enrolled in the main study. RESULTS: The CRP levels peaked 3 days postoperatively, and then decreased to baseline levels at 15-28 days postoperatively. Within 14 days postoperatively, the CRP levels were significantly higher in the simultaneous bilateral TKA group than in the unilateral group (p<0.01). Thereafter, no significant difference in CRP levels existed between two groups. After the 8th postoperative day, a significant difference in CRP level existed between patients with and without deep prosthesis infections. CONCLUSION: CRP changes post-TKR provide an effective means of monitoring of infections. In cases of non-inflammatory arthritis in which the CRP levels are significantly difference after the 8th postoperative day or are elevated after the 4th postoperative week, an infection should be suspected.

PURPOSE: We wanted to measure the size of the osteolysis of the pelvis and to quantify its location and we wanted to assess the correlation of these measurements with the clinical result. MATERIALS AND METHODS: We evaluated 40 hips (31 patients) that showed definitive osteolysis among 116 hips (97 patients) that underwent 3 dimensional CT scanning post-operatively after total hip arthroplasties with using cementless acetabular cups. The inclusion criteria were a follow up duration of more than 18 months and no history of infection. The radiographs were obtained at the 6th to 12th week postoperatively. The size of pelvic osteolysis was divided into 4 groups (less than 1 cm3 (A), between 1 cm3 to 2 cm3 (B), between 2 cm3 to 3 cm3 (C), more than 3 cm3 (D)), and the location of osteolysis was divided into 5 groups (anterior, posterior, superior, inferior and central) The size and location of osteolysis and the wear of the polyethylene were analysed in relation to the clinical outcome, which was assessed using the Harris Hip Score). RESULTS: The average size of the osteolysis was 3.2 cm3 (A 14 cases in group A, B 11 cases in group B, C 4 cases in group C, and D 11 cases in group D). There was significant correlation between the size of the osteolysis and the clinical outcome (Rs=-0569). However, there was no significant correlation between the osteolysis location (Anterior: 18 cases, Superior: 5 cases, Posterior: 10 cases, Inferior: 33 cases and Central: 32 cases) and the clinical outcome (P=0.35). CONCLUSION: There is a significant correlation between the size of the osteolysis and the Harris Hip Score (Rs=- 0569). Especially, a pelvic osteolysis of more than 3 cm3 was found to be correlated with a decreased postoperative HHS (P=0.022). We hope that these results may be useful to help guide the treatment of osteolysis.
