After wide excision of proximal humeral bony malignancy, prognosis-based reconstruction was performed at Taipei Veterans General Hospital. Bone prosthesis composite (BPC) was carried out among patients with a favored prognosis, while cement-spacer prosthesis composite (CSPC) was preserved for patients with poor prognosis. The aim of our study is to compare the clinical outcomes between the BPC and CSPC reconstruction procedures. From January 2000 to December 2014, we retrospectively reviewed the clinical outcomes of 34 patients who underwent shoulder hemiarthroplasty following wide excision of a malignant lesion of the proximal humerus, 15 of whom were treated with a BPC reconstruction and 19 cases were treated with a CSPC reconstruction...

Giant cell tumor of the bones occurring in the first metacarpals frequently requires entire metacarpal resection due to the aggressive nature and high rate of recurrence. Bone reconstruction can be performed with autogenous bone grafts. Here we describe a new technique of reconstruction using a patient-matched three-dimensional printed titanium first metacarpal prosthesis. This prosthesis has a special design for ligament reconstruction in the proximal and distal portions. Good hand function and aesthetic appearance were maintained at a 24-month follow-up visit...

BACKGROUND: The aseptic lymphocyte vasculitis-associated lesion (ALVAL) score and the modified Oxford ALVAL score are frequently used scoring methods to evaluate the morphologic features of periprosthetic tissues around metal-on-metal (MoM) hip implants. Except for the initial studies of these two morphology scoring methods, to our knowledge, no other studies have reported on intraclass correlation coefficient (ICC) values for interobserver reliability of these scoring methods. QUESTIONS/PURPOSES: Are the ALVAL and Oxford ALVAL scores reproducible? METHODS: The periprosthetic tissue of 37 revisions of 36 patients with failed MoM THAs were independently scored by three experienced pathologists using ALVAL and Oxford ALVAL scoring methods...

BACKGROUND: Among various types of composite biological reconstruction, pasteurized autograft-prosthesis composite (PPC) is popular when allograft is unavailable. Previous limited cohort study indicated result comparable to tumor prosthesis. However, as case number and follow-up increase, we experienced more complications than anticipated. We questioned the usefulness of PPC as a viable reconstructive option. METHODS: We reviewed 142 PPCs and analyzed overall and location-related survival and factors associated with the failure of PPC...

The aim of this study was to design a hemi-pelvic prosthesis for a patient affected by pelvic sarcoma. To investigate the biomechanical functionality of the pelvis reconstructed with designed custom-made prosthesis, a patient-specific finite element model of whole pelvis with primary ligaments inclusive was constructed based on the computed tomography images of the patient. Then, a finite element analysis was performed to calculate and compare the stress distribution between the normal and implanted pelvis models when undergoing three different static conditions-both-leg standing, single-leg standing for the healthy and the affected one...

BACKGROUND: Pathological fracture of the proximal femur is a main cause of cancer patients losing their ability to walk. Although both osteosynthetic devices (predominantly intramedullary nails) and prosthetic replacement have been widely performed for treatment, controversies exist regarding which procedure should be used for the various conditions. In order to decide the eligibility criteria of a planned randomized prospective study about the treatment of pathological fractures of the proximal femur, we assessed the factors affecting the selection of operative procedures using questionnaires sent to the members of the Bone and Soft Tissue Tumor Study Group (BSTTSG) of the Japan Clinical Oncology Group (JCOG)...

Breast lymphomas comprise a rare group of malignant breast tumors. Among these, a new entity has emerged as a potentially under-diagnosed disease. Breast implant-associated anaplastic large cell lymphoma (BI-ALCL) most often manifests as a late periprosthetic effusion between 1 and 10 years after the implantation of silicone or saline-filled breast prostheses. BI-ALCL is an anaplastic lymphoma kinase-negative T-cell lymphoma that has a distinctively different clinical course than other breast lymphomas or ALCLs...

BACKGROUND AND PURPOSE: Impending or pathological fractures due to bone metastases may require surgical fixation. Postoperative radiation is often recommended to reduce local progression and prevent prosthesis displacement, hence reducing the need for second surgery. The objectives of this study were to investigate the need for second surgery, and to report on rates of re-irradiation, tumor progression and prosthesis displacement following postoperative radiation. MATERIALS AND METHODS: Data were collected from 65 patients who received postoperative radiation to 74 sites in the extremities in a palliative radiation clinic between January 2009 and January 2017...

Introduction: For chronic prosthetic joint infections (PJI), complete removal of the infected prosthesis is necessary in order to cure the infection. Unfortunately, a subgroup of patients is not able to undergo a revision surgery due to high surgical risk. Alternatively, these patients can be treated with antibiotic suppressive therapy (AST) to suppress the infection. Aim: To evaluate the efficacy and tolerability of AST. Methods: We retrospectively collected data (period 2009-2015) from patients with a PJI (of hip, knee or shoulder) who were treated with AST at the University Medical Center Groningen, the Netherlands...

BACKGROUND: Disseminated Histoplasmosis (DH) is a rare manifestation of Acquired Immune Deficiency Syndrome (AIDS) in European countries. Naso-maxillar osteolysis due to Histoplasma capsulatum var. capsulatum (Hcc) is unusual in endemic countries and has never been reported in European countries. Differential diagnoses such as malignant tumors, cocaine use, granulomatosis, vasculitis and infections are more frequently observed and could delay and/or bias the final diagnosis. CASE PRESENTATION: We report the case of an immunocompromised patient infected by Human Immunodeficiency Virus (HIV) with naso-maxillar histoplasmosis in a non-endemic country...

Large maxillofacial defects from malignant tumor treatment are rarely rehabilitated by surgical reconstruction alone. Ameloblastic carcinoma, a rare aggressive odontogenic malignant tumor, requires wide surgical excision to gain a tumor-free margin. In the post-surgical defect, prosthetic rehabilitation is the treatment of choice to restore function and esthetics. Moreover, an intra-oral prosthesis such as an obturator restores speech, mastication and deglutition. Retention of the obturator is a major problem while rehabilitating large defects...

Tumor involvement of the inferior vena cava (IVC) by hepatobiliary, pancreatic or duodenal malignancies can compromise adequate resection. However, radical resection with negative histological margins remains the only chance of cure. Various techniques are used for venous reconstruction, using a prosthetic graft interposition in most of the cases. However, in case of associated digestive resections, such as pancreaticoduodenectomy, postoperative complications can be responsible for prosthesis infection and related vascular complications...

STATEMENT OF PROBLEM: Restoration of maxillary defects resulting from tumor ablative surgery presents a difficult challenge, with both functional and esthetic issues. Whether rehabilitation with an obturator prosthesis could significantly contribute to improved quality of life in patients with maxillary resection has been scarcely studied, with relatively small study samples. PURPOSE: The purpose of this survey study was to assess the overall functioning of the obturator prosthesis and the effect of specific sociodemographic, medical, and treatment variables on obturator functioning and quality of life in patients with maxillectomy...

BACKGROUND: Distal femoral endoprosthesis (DFE) has become the optimal method of reconstruction in the skeletally mature patients treated for malignant bone tumor. Albeit literature has reported wide range of aseptic loosening in cemented components (6-32%), few authors showed that cement was not detrimental to long-term success of primary distal femoral implants possibly relating to cementing technique. METHODS: A series of consecutive of DFE (MRS and GMRS, Styker Orthopaedics, Mahwah, NJ) was retrospectively reviewed for evidence of loosening on plain radiographs...

Cardiac myxomas are the most common type of primary cardiac tumors. They mainly affect the interatrial septum and exceptionally the heart valves. Surgical excision remains the only therapeutic alternative. We here report the case of a 69-year old patient with no significant pathological history suffering from NYHA class II-III dyspnea associated with lipothymia. Transthoracic echocardiography showed a tight calcified aortic narrowing with aortic valve gradient of 58 mmHg. A sessile mass of 15mm diameter inserted into the posterolateral leaflet, without stenosis or mitral regurgitation evoking an atypical localization of myxomaor or fibroelastoma was detected at the level of the mitral valve...
