PURPOSES: Osteonecrosis of the femoral head (ONFH) is a dramatic condition resulting in joint destruction in the late stages. Total hip arthroplasty allows function recovery with satisfactory implant survival. Recently, the use of uncemented short stems has been suggested to improve the conservation of bone stock. METHODS: We performed a retrospective study on 16 hip arthroplasties-11 patients-implanted for ONFH between 2008 and 2017. We aimed to compare the outcomes of the two types of arthroplasty-"uncemented short" vs "cemented conventional" femoral stem-in terms of pain (visual analogue scale), function (Harris Hip Score), and survival (radiography)...

PURPOSE: Degenerative disc disease involves sequential events that lead to the loss of cells, a decrease in disc matrix production, disc dehydration, and alteration of its biomechanical properties. The aim of this study was to determine whether cryoinjury of the nucleus pulposus performed through endplate perforation contributes to disc degeneration and to compare this technique with standard methods. METHOD: Under general anesthesia, the lumbar discs of six pigs were exposed and randomly submitted to needle puncture of the annulus fibrosus (NeP), isolated endplate injury (EP), or cryoinjury using a 2...

BACKGROUND: Metaphyseal-diaphyseal junction (MDJ) fractures of the distal humerus are problematic to reduce and more susceptible to post-operative complications. This biomechanical study was designed to compare Kirschner wires (KW), lateral external fixation, and elastic stable intramedullary nails (ESIN) in simulated transverse MDJ fractures of various heights. METHOD: Sagittally oblique, transverse MDJ fractures were created in fourth-generation composite bone models at three levels: high, mid, and low fractures, respectively, and then fixed with either Kirschner wires, lateral external fixation (EF), or ESIN respectively and tested in extension, flexion, valgus, varus, internal, and external rotations...

PURPOSE: Symptomatic osteonecrosis related to corticosteroids has a high risk of progression to collapse in absence of treatment. The purposes of this study were to evaluate the results of autologous bone marrow grafting of the symptomatic hip in adult patients with osteonecrosis and to compare the results with core decompression alone in the contralateral symptomatic hip. MATERIALS AND METHODS: A total of 125 consecutive patients (78 males and 47 females) with bilateral osteonecrosis (ON) and who had both hips symptomatic and at the same stage on each side (stage I or II) were included in this study from 1988 to 1998...
