Risk factors for one-year mortality in 440 femoral peri-implant fractures: insights from the PIPPAS prospective, multicentre, observational study.

Aims: The Peri-Implant and PeriProsthetic Survival AnalysiS (PIPPAS) study aimed to investigate the risk factors for one-year mortality of femoral peri-implant fractures (FPIFs).

Methods: This prospective, multicentre, observational study involved 440 FPIF patients with a minimum one-year follow-up. Data on demographics, clinical features, fracture characteristics, management, and mortality rates were collected and analyzed using both univariate and multivariate analyses.

Difficulties associated with the variable geometry of different-offset Exeter long stems in cement-in-cement technique: A case report.

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 long stem was exchanged by a shorter and smaller size 37.

Stability evaluation after isolated reconstruction of anteromedial or posterolateral bundle in symptomatic partial tears of anterior cruciate ligament.

Objective: To evaluate the stability achieved in isolated reconstruction of each ACL bundles (minimum 2-year follow-up).

Study Group: 39 consecutive patients (28.1 years of mean age) underwent anteromedial (AM) and posterolateral (PL) bundle reconstruction surgery (31.

[Quality of life following surgical treatment of malignant middle cerebral artery infarction].

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 analysed 21 patients one year after their operation.

Evaluation of autologous platelet concentrate for intertransverse lumbar fusion.

Introduction: 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.

Materials And Methods: A prospective, controlled, blinded, non-randomized clinical trial was carried out in 107 patients affected by degenerative lumbar pathology. The study group consisted of 67 patients, in which autologous platelet concentration was added to a mixture of autologous local bone graft and TCP/HA.

[Minimally invasive posterior approach in total hip arthroplasty. Prospective randomised trial].

Background: 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.

Minimally invasive subvastus approach: improving the results of total knee arthroplasty: a prospective, randomized trial.

Background: Minimally invasive knee arthroplasty seeks to diminish the problems of traditional extensile exposures aiming for more rapid rehabilitation of patients after surgery.

Questions/purposes: 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.

Methods: One hundred patients were enrolled in a prospective, randomized trial.

Radiographic analysis of fusion mass using fresh autologous bone marrow with ceramic composites as an alternative to autologous bone graft.

Objective: 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.

Materials And Methods: A prospective nonrandomized, radiographic study on 35 patients with posterolateral fusion using rigid transpedicular instrumentation for degenerative lumbar disease. At least 2-year follow-up.
