PURPOSE: The clinical and radiographic outcomes after revision total knee arthroplasty (TKA) for instability with two rotating hinge knee prostheses were compared. METHODS: Fifty-one patients revised for TKA instability were prospectively randomized to either the Link Endo-Model (N = 26) or the EnduRo (N = 25). Clinical and radiographic outcome scores were compared pre-operatively and at 12 months' follow-up. Failure mechanisms were recorded. RESULTS: Age, BMI, operation, and tourniquet-time did not differ significantly between groups...

Introduction: High tibial osteotomy (HTO) is a frequent and effective treatment for unicompartmental gonarthritis. Only a few articles are focused on the treatment of infected nonunion. Patient and Method: A 50-year-old obese patient was operated on by medial opening-wedge HTO. She developed a painful nonunion treated by hardware removal, allograft, and plate fixation. However, the nonunion persisted. 2 years later, cellulitis appeared with an abscess adjacent to the HTO plate...

Background: Cranial defects usually occur after trauma, neurosurgical procedures like decompressive craniotomy, tumour resections, infection and congenital defects. The purpose of cranial vault repair is to protect the underlying brain tissue, to reduce any localized pain and patient anxiety, and improve cranial aesthetics. Cranioplasty is a frequent neurosurgical procedure achieved with the aid of cranial prosthesis made from materials such as: titanium, autologous bone, ceramics and polymers...

BACKGROUND: Preoperative ankle coronal malalignment has been considered as a risk factor for poor outcomes and failure after total ankle arthroplasty. The present study evaluated whether intermediate to long-term outcomes of total ankle arthroplasty in ankles with preoperative varus and valgus malalignment (5° to 20°) are comparable with those with neutral alignment (<5°). METHODS: We enrolled 144 consecutive ankles that underwent primary total ankle arthroplasty (140 patients) using a mobile-bearing HINTEGRA prosthesis with a minimum follow-up of 4 years; the mean overall follow-up duration was 89 months (51 to 145 months)...

Phantom limb pain (PLP) develops in most patients with lower limb amputation. Changes in the peripheral and central nervous system (CNS) are hypothesized to contribute to PLP. Based on ideas to modify neural reorganization within the CNS, the aim of the study was to test, whether prostheses with somatosensory feedback might help to reduce PLP, and increase the functionality of movement with a prosthesis. We therefore equipped the prostheses of 14 lower leg amputees with a simple to use feedback system that provides electrocutaneous feedback to patients' thigh whenever the foot and toes of the prosthesis touch the ground...

The Longobard necropolis of Povegliano Veronese dates from the 6th to the 8th centuries AD. Among the 164 tombs excavated, the skeleton of an older male shows a well-healed amputated right forearm. The orientation of the forearm fracture suggests an angled cut by a single blow. Reasons why a forearm might be amputated include combat, medical intervention, and judicial punishment. As with other amputation cases reported in literature, this one exhibits both healing and osteoblastic response. We argue that the forelimb stump morphology suggests the use of a prosthesis...

INTRODUCTION: Dysphagia is a frequent postoperative symptom after anterior cervical disc arthroplasty. However, onset of dysphagia and neck pain a long time after surgery should suggest a diagnosis of prosthesis dislocation. CARE REPORT: A 65-year-old man with a history of cervical disc arthroplasty 27 years previously consulted for rapidly progressive dysphagia with no other associated symptoms. Physical examination and CT scan confirmed the diagnosis of anterior dislocation of the prosthesis with no signs of perforation...

INTRODUCTION: Minimally invasive cardiac surgery (MICS), via minithoracotomy, is thought to be a fast track to extubation and recovery after surgery. Chronic pain, due to intercostal nerve injury, develops in up to 50% of postthoracotomy patients.A number of regional anaesthesia and analgesia techniques may be employed, and the anaesthesiologists play a key role in facilitating optimal outcomes after surgery. METHODS: We report a case of postoperative pain management with a local anesthetic infiltration for MICS...

BACKGROUND: To date, no gold standard for the surgical treatment of femoral hernia exists. Pure tissue repair as well as mesh/plug implantation, open or laparoscopic, are the most performed methods. Nevertheless, all these techniques need sutures or mesh fixation. This implies the risk of damaging sensitive structures of the femoral area, along with complications related to tissue tear and postoperative discomfort consequent to poor quality mesh incorporation. The present retrospective multicenter case series highlights the results of femoral hernia repair procedures performed with a 3D dynamic responsive implant in a cohort of 32 patients during a mean follow up of 27 months...

BACKGROUND: There has been a recent interest in custom-made partial knee arthroplasties to provide patient-specific instrumentation and better fit of the prosthesis. While unicondylar knee arthroplasties (UKAs) have demonstrated good outcomes and durable results in many studies, there is little evidence on outcomes of these custom-made implants. METHODS: We performed a retrospective review of all custom-made UKAs performed at our institution by one surgeon from 2008 to 2015...

Rotator cuff is a vital structure of glenohumeral joint, the dysfunction of which leads to debilitating pain and restricted movement. Arthroplasty using unconstrained anatomical prosthesis for treating these conditions have not been successful in the past. Reverse Shoulder Arthroplasty (RSA) is a novel technique specifically designed to address end stage glenohumeral arthritis in rotator cuff deficient joint. Short and mid-term studies have demonstrated a significant improvement in pain and range of motion of the shoulder joint...

OBJECTIVES: Patients suffering from osteoarthritis, ankylosis (e.g. post-trauma or tumour) in the temporomandibular joint (TMJ) can present with symptoms such as severely restricted mouth opening, pain or other dynamic restrictions of the mandible. To alleviate the symptoms, a total joint prosthesis can be indicated, such as the Groningen TMJ prosthesis. This was developed as a stock device with a lowered centre of rotation for improved translational and opening capacity. This study aimed to improve the design of the prosthesis, and produce a workflow for a customized Groningen TMJ prosthesis, in order to make it more accurate and predictable...

The most common reason for lower limb amputations in the UK is peripheral arterial disease. A thoughtful approach to surgery, with consideration of optimal amputation level and residual limb shape, can improve prosthetic use and functional outcomes. Prosthesis socket design and fit, as well as use of appropriate components, must be considered in accordance with the patient's activity level and potential. Major developments in prosthetics over the past 20 years, particularly in the area of joint design, including microprocessor knees, have increased options to improve ambulation...
