Although the cement in cement technique is a simple method for exchanging cemented stems, it may be technical demanding. The different geometry of different-offset Exeter long stems can be a problem with this technique. We describe a case revision hip surgery as a consequence of neglected bipolar hemiarthroplasty dislocation in which a 44 mm offset...

Objective: Long term clinical and radiological evaluation of results, survival, and peri- operative and post-operative complications of the patients who have been operated on for revision total hip arthroplasty using the impaction allografting and cemented rod technique. Material and methods: An observational, analytical, prospective and non-ran...

Resumen Objetivo Evaluar a largo plazo, el resultado clínico-radiológico, la supervivencia y las complicaciones intra y postoperatorias de pacientes intervenidos de cirugía de revisión de cadera mediante esta técnica. Material y métodos Estudio analítico observacional, prospectivo y no aleatorizado de 26 pacientes intervenidos de cirugía de revis...

Introduction: The functional outcome in patients after decompressive craniectomy in malignant middle cerebral artery infarction has been widely reported. But there are no many studies about the neuropsychological deficits in these patients. Our main aim is to analyse this neuropsychological sequelae. Methods: Neuropsychological test in these patien...

We hypothesized that minimally invasive surgery was superior to conventional surgery for total hip arthroplasty procedure. To compare the results of total hip replacement (THR) made by minimally invasive lateral approach with the results of THR made by conventional lateral approach. Prospective, randomized trial. Fifty patients were selected and th...

Introduction: Little work has been published on the capacity to adapt to the disease of patients with malignant middle cerebral artery infarction who have undergone decompressive surgery. The purpose of this study is to analyse the final quality of life and the degree of satisfaction of patients and their relatives. Patients and methods: We anal...

Objective To evaluate the stability achieved in isolated reconstruction of each ACL bundles (minimum 2-year follow-up). Materials and methods Study group: 39 consecutive patients (28.1 years of mean age) underwent anteromedial (AM) and posterolateral (PL) bundle reconstruction surgery (31.71 months of mean follow-up). Control group: 36 non-concurre...

Osteoporosis is characterized by low bone mineral density (BMD). This illness has a high-cost impact in all developed countries. The aim of this article is the development of a mathematical method able to predict the BMD of post-menopausal women, taking into account only certain nutritional variables. This research applies neural networks for the s...

The aim of the study was to analyze if the adding of autologous platelet concentrate (APC) to a mixture of local autograft plus tricalcium phosphate and hidroxiapatite (TCP/HA) would improve the fusion rate in posterolateral lumbar fusion. A prospective, controlled, blinded, non-randomized clinical trial was carried out in 107 patients affected by...

Backgrond. Our working hypothesis was that minimally invasive surgery was superior to conventional surgery for total hip arthroplasty procedure. We compared THR results in the minimally invasive posterior approach with THR results in the conventional posterior approach. Methods. Prospective, randomised trial. Fifty patients were selected and then d...

We compared THR results in the minimally invasive posterior approach with THR results in the conventional posterior approach. Prospective, randomised trial. Fifty patients were selected and then divided into two grou...

PurposeTo compare the results of minimally invasive total hip replacement (THR) with those of conventional THR.

Purpose: To compare the results of minimally invasive total hip replacement (THR) with those of conventional THR. Materials and methods: This is a prospective randomized clinical study. 50 patients were selected, who were divided into 2 groups depending on the surgical approach they were subjected to, i.e. a minimally invasive direct lateral approa...

Minimally invasive knee arthroplasty seeks to diminish the problems of traditional extensile exposures aiming for more rapid rehabilitation of patients after surgery. To determine if the subvastus approach results in less perioperative pain and blood loss, shorter hospital stay, and improved function at both early and long-term followup. One hundre...

In this work, the application of ‘multivariate adaptive regression splines’ (MARS) for modelling osteoporosis is described. This article focuses on the explanation of a new technique that combines the use of the principal components analysis (PCA) method with MARS. The use of this new technique allows for an easier management of large databases wit...

Our objective was to compare the results of PCCP (Percutaneous Compression Plate) device and Gamma 3 nail for the treatment of stable trochanteric hip fractures and to demonstrate that PCCP device is a minimally invasive system. Prospective, randomized trial. Eighty patients aged 60 and over with stable trochanteric fracture were selected and then...

To determine whether a biphasic calcium phosphate (BCP) ceramic supplemented with fresh autologous bone marrow (BMA) can give rise to adequate bone to achieve a vertebral fusion mass. A prospective nonrandomized, radiographic study on 35 patients with posterolateral fusion using rigid transpedicular instrumentation for degenerative lumbar disease....

Aim To assess the use of cryopreserved arterial allograft membranes in guided bone regeneration (GBR) in bone defects of long bones. Materials and methods Prospective randomized blind study using white New Zealand rabbits as an animal model. Bone and periosteum defects 10 mm in length were created in the middle third of the shaft of the radius of...

Morsellized bone-graft handling during spine surgery to get vertebral fusion can be a slow, laborious and time-consuming procedure. It is not absolutely exempt from complication risk. An easy, quick and inexpensive alternative technique is described.

Surgical field illumination and visualization is the key for total hip arthroplasty through a mini-incision approach. An easy, quick, and inexpensive method is described, using a conventional endoscopic light-source temporally fixed to conventional hip surgery retractors.

For revision knee surgery with uncontained tibial bone defects, the authors report the containment of compacted morsellized allograft using metal-wire mesh, followed by implantation of a cemented total knee prosthesis. This method is comparable to the "impaction grafting technique" described for revision hip surgery and could be an alternative to m...

We report a study of 2 surgical approaches to the knee in 42 consecutive patients undergoing a total arthroplasty. They were divided into 2 groups. In Group 1 (n=17) the knee was exposed through classic medial parapatellar arthrotomy and in Group 2 (n=25) the knee was approached through the fibers of the medial vastus. Preoperative assessment did n...

Handling morcellized bone-graft during impaction grafting can be a slow and laborious procedure. An alternative quick technique is described.

Resumen.—Se han revisado 27 quistes óseos esenciales con una edad media de 13,4 años y un seguimiento medio de 6 años. Valorados clínica y radiológicamente conforme a los criterios de Neer, no se ha observado curación espontánea en los quistes que se dejaron evolucionar (5 casos), ni en ninguno de los que presentaron una fractura a su nivel (16 ca-...

Thirty-one cases of isolated fracture of the radial head were treated by surgical resection. Mean age was 49 years and mean follow-up was 6 years. Clinical, functional and radiological evaluation disclosed excellent or good results in 74%. Twenty-nine percent of patients had arthritic or degenerative signs and 26% had periarticular calcifications....
