Previous studies of outcomes following pedestal acetabular prosthesis have shown that the most common complications were dislocation and infection with rates ranging from 10–26% and 11–47% respectively. \u0000 Methods: A case series review of all acetabular reconstructions performed between 2003 and 2016 using a pedestal prosthesis was performed using data from the Royal Orthopaedic Hospital oncology database. Patient demographics and primary diagnoses were recorded, as was length of follow up, complications rate, patient and implant survivorship. Results: We identified 52 cases of acetabular reconstruction for pelvic malignancy between 2003 and 2016. The average follow-up was 4 ½ years with a 27% complication rate. The deep infection rate was 8% with half of these requiring removal of implants. The dislocation rate was 12%. The use of intra-operative computer navigation reduced the rate of dislocation by half when compared to cases where navigation was not used. Conclusions: The complication rates associated with a stemmed acetabular endoprosthesis are to other reconstructive techniques for acetabular defects. There was a significant decrease in dislocation rate when intra-operative navigation was used. Similarly, the rate of deep infection was also one of the lowest reported in literature. When used for metastatic pelvic disease there was a 100% implant survivorship.","PeriodicalId":44459,"journal":{"name":"Annals of Joint","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21037/aoj.2019.06.04","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42044548","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several studies have demonstrated high morbidity and mortality rates associated with several osteoporotic fracture types. The purpose of this study was to investigate and compare the risk factors, morbidity, mortality and cost of proximal humerus, distal radius, hip and vertebral compression fractures. Methods: From the Medicare Registry, patients diagnosed with a proximal humerus, distal radius, hip or vertebral compression fracture based on the ICD-9 coding were identified. Sex, race, age, fracture type, healthcare cost, mortality, blood transfusion requirement, and comorbidities were documented. Results: Between 2010 and 2014 there were 50,237,330 inpatient claims and 1,183,966 (2.4%) of those were specifically for 1 of the 4 osteoporotic fracture types. Mortality rate during index admission for all four fractures combined was 2.2%. Mortality rate was 1% for proximal humerus, as compared to 0.4% for distal radius, 2.5% for hip and 1.8% for vertebral compression fractures. The highest cost was associated with hip fractures and the lowest cost with distal radius fractures. The hip and vertebral compression fracture patients had the most documented comorbidities. Patients were more likely to be female (OR 2.105, 95% CI: 2.096–2.113), white (OR 2.600, 95% CI: 2.582–2.617), and over 84 years of age (OR 5.979, 95% CI: 5.957–6.001) in all fracture types. Conclusions: Proximal humerus fractures carry similar risk factors, morbidity, mortality, and health care costs as other osteoporotic fracture types. The findings of the present study are clinically relevant, as life expectancy continues to increase and the Medicare population continues to grow. This will lead to an increase in the incidence of osteoporotic fractures. Proper screening and treatment of osteoporosis may help prevent some of these fractures.","PeriodicalId":44459,"journal":{"name":"Annals of Joint","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21037/AOJ.2019.01.01","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47055364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous work has shown that anti-rotation pins improve rotational stability at the bone-implant interface, but there is concern that these pins lead to increased risk of mechanical failure. We asked: (I) are anti-rotation pins used with the Compress implant associated with mechanical failure? (II) Are anti-rotation pins associated with less effective osseointegration? Methods: We performed retrospective review of cases using a Compress implant from 2004–2016. Mechanical failure rates and bone growth at the bone-implant interface were compared between pin and no-pin cohorts. Regression models were used to examine patient and surgical factors associated with mechanical failure. \u0000 Results: Anti-rotation pins were not associated with mechanical failure (P=1.0, odds ratio 1.17, 95% confidence interval: 0.12–15.40). Anti-rotation pins were not associated with impaired osseointegration at any time point (P=1.0 at 3–6 months, P=0.33 at 6-9 months, P=0.34 at 9–12 months, P=0.40 at 12–24 months, P=0.28 at 24–48 months, P=1.0 at >48 months).

Here, we present two cases of MIAP due to pancreatic metastasis of osteosarcoma. Case 1: a 47-year-old woman was referred to our hospital due to osteosarcoma at left femur. She felt back pain 2 years postoperatively. An abdominal CT showed a 7 cm mass in the pancreatic head. Considering that the acute pancreatitis due to pancreatic metastasis, palliative radiotherapy was performed. Although abdominal pain was improved, she had died of multiple metastasis after 2 months. Case 2: a 42-year-old woman was referred to our hospital due to osteosarcoma at left femur. She felt abdominal and back pain 6 months after initial treatment. CT scans showed a large mass in the pancreatic tail. The mass increased rapidly over a short duration and complicated the acute pancreatitis. Palliative radiotherapy (30 Gy/10 fractions) was performed. After 1 month, the patient died of lung metastases. In previous reports, all patients with pancreatic metastases from osteosarcoma developed metastases at other sites, such as the lungs and bone. Therefore, we suggest that follow-up examinations at the abdominal lesion may be necessary for patients with metastatic disease.","PeriodicalId":44459,"journal":{"name":"Annals of Joint","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21037/aoj.2019.09.05","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43074901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given that the pelvic bone has a complex geometry with intricately related vital neurovascular structures, surgeons may resect tumours with more margin than oncologically necessary when taking into account the inaccuracy in planning and resection. The lesser normal bone may be retained for reconstruction to restore limbs function. Therefore, bone sarcoma locating near the acetabulum is often resected including the entire acetabulum. Partial acetabular resection of bone sarcoma with pelvic reconstruction has been described in selected patients with periacetabular tumours in a few case series. Early promising results were reported with the advantages of preserving more host bone for reconstruction without compromising the oncological resection margin and increasing the risk of local recurrence when the surgeries were performed with good preoperative planning and guided resection under computer navigation guidance. This article is to review the pelvic reconstruction after partial acetabular resection of bone sarcoma, its pathoanatomy, surgical considerations, current evidence and limitations.","PeriodicalId":44459,"journal":{"name":"Annals of Joint","volume":" ","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.21037/AOJ.2019.04.02","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46032206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
