Reconstruction of the anophthalmic socket allows the use of an ocular prosthesis and rehabilitation of facial appearance. Dermis-fat grafting is one option in volume augmentation of the anophthalmic socket and presents unique benefits, including increased surface area within the socket and the ability to grow with pediatric patients. Postoperative complications of this procedure are relatively common. Minor complications, such as graft hirsutism, keratinization, and conjunctival cysts or granulomas, are managed easily by observation or simple intervention...

Limb sparing surgery in growing young patients with malignant tumors is difficult as invasion of the physis by the tumor or surgical resection through the metaphysis may cause significant limb discrepancy following surgery. At present, hinged tumor prosthesis or biological reconstructions are the main methods following tumor resection in these patients. The aim of the present study was to assess different procedures for the treatment of osteosarcoma around knee joints in immature patients. A retrospective study of 56 patients (<15 years old, open physis) who had been treated for osteosarcoma around the knee joint between January 2007 and December 2015 was performed...

Total knee replacement is a common treatment for advanced knee osteoarthritis. The most common and widespread method is cemented arthroplasty. As in the prosthetic hip a gradual transition from cemented to uncemented fixation techniques occurred over time, increasing interest is growing also around cementless knee fixation, with the theoretical advantages of preserving the bone stock and obtaining a biological fixation avoiding cement fragmentation. On the basis of the actual knowledge, the uncemented knee prosthesis represents an interesting alternative especially for the patient under 65 years of age, with viable bone quality, in which a biological bone-prosthesis fixation is desirable, while avoiding the drawbacks of cement fragmentation and of the possible future revision of a cemented implant...

the use of amplatzer occluder family in daily clinical practice has already overcome on-label indications, with growing clinical experience and the technological evolution of devices. Areas covered: We present the case of a patient with a very rare complication following proximal aortic surgery treated using a unique strategy. A huge pseudoaneurysm around an ascending aortic prosthesis ruptured into the right pulmonary artery. A hybrid treatment strategy consisting of percutaneous closure of the fistula followed by cardiosurgery was chosen due to the patient's poor haemodynamic condition...

Radial head prostheses (RHP) have been developed to decrease the complications rate following a radial head resection surgery. The aim of the RHP is to replicate the physiological radiocapitellar tracking, reproducing the mechanical function of the native radial head: to stabilize the elbow and to shear the forces passing through the elbow along with the other stabilizers. The currently used RHP models try to achieve this target with three different prosthesis' strategies: (a) loose fit stem, (b) bipolar radial head or (c) anatomical radial head...

BACKGROUND: While rehabilitation professionals are historically trained to place emphasis on the restoration of mobility following lower limb amputation, changes in healthcare dynamics are placing an increased emphasis on the limb loss patient's quality of life and general satisfaction. Thus, the relationship between these constructs and mobility in the patient with lower limb loss warrants further investigation. OBJECTIVES: To determine the relationship between mobility of the patient with lower limb loss and both (1) general (1) general satisfaction and (2) quality of life...

Replacement with a prosthetic device remains a major treatment option for the patients suffering from heart valve disease, with prevalence growing resulting from an ageing population. While the most popular replacement heart valve continues to be the bioprosthetic heart valve (BHV), its durability remains limited. There is thus a continued need to develop a general understanding of the underlying mechanisms limiting BHV durability to facilitate development of a more durable prosthesis. In this regard, computational models can play a pivotal role as they can evaluate our understanding of the underlying mechanisms and be used to optimize designs that may not always be intuitive...

Percutaneous osseointegrated (OI) prostheses directly connect an artificial limb to the residual appendicular skeleton via a permanently implanted endoprosthesis with a bridging connector that protrudes through the skin. The resulting stoma produces unique medical and biological challenges. Previously, a study using a large animal amputation model indicated that infection could be largely prevented, for at least a 12-month period, but the terminal epithelium continued to downgrow. The current study was undertaken to test the longer-term efficacy of this implant construct to maintain a stable skin-implant interface for 24 months...

Transcatheter aortic valve replacement has emerged as valuable treatment modality for patients with severe aortic stenosis and an unacceptable risk/benefit ratio for open heart surgery, but particularities specific to TAVR and a rapidly growing number of available TAVR prosthesis make post-procedural assessment of valve function challenging. Aim of the present analysis was to collect and pool all available data currently in the literature regarding normal doppler values for transcatheter prosthetic heart valves and to provide a comprehensive overview...

Retinoblastoma is the most frequent intraocular tumour in childhood. The definitive treatment is enucleation. The management of the anophthalmic socket consists in the use of a plastic implant. The problem is that they are expensive and they usually extrude. The use of dermal-fat grafts minimises the hemi-facial hypoplasia. They usually grow with the face, and help to expand the orbital bones, thus avoiding the psychological and physical consequences. OBJECTIVE: To determine if there is hemi-facial hypoplasia, using MRI images after the use of a dermal-fat implant in patients enucleated for RB...

INTRODUCTION: Surgical frailty is a previously unrecognized clinical entity that objectifies a multiorgan decrease in physiologic reserve in those undergoing surgery. Although penile implantation has been demonstrated to be an effective means of restoring erectile function in patients whose previous conservative measures have failed, there are limited data regarding the assessment of frailty in patients undergoing penile implantation. AIM: To review the various objective methods used to describe surgical frailty in medical and surgical disciplines, report on methodologies of frailty assessment, and discuss the relevance of surgical frailty in the preoperative evaluation of patients undergoing implantation of an inflatable penile prosthesis...

The search for an optimal aortic valve implant with durability, calcification resistance, excellent haemodynamic parameters and ability to withstand mechanical loading is yet to be met. Thus, there has been struggled to fabricate bio-prosthetics heart valve using bioengineering. The consequential product must be resilient with suitable mechanical features, biocompatible and possess the capacity to grow. Defective heart valves replacement by surgery is now common, this improves the value and survival of life for a lot of patients...

Background Total knee replacement is the only surgical option to treat painful degenerative osteoarthritis, restore knee function, improve quality of life, and enable patients to return to sports activity. With an aging population expecting an active life after retirement, patients' expectations of improvement after surgery are increasing as well. In view of the growing demand for higher performance, exercise and athletic activity, clinicians have been increasingly forced to question how much athletic activity a patient may resume after total knee replacement, and what types of athletic activity seem to be acceptable...
