Locking plate fixation versus antegrade nailing of 3- and 4-part proximal humerus fractures in patients without osteoporosis. Comparative retrospective study of 63 cases.

Introduction: There is no consensus on the treatment of proximal humeral fractures. The goal of the present retrospective observational study was to compare functional and radiological results and complications of internal fixation using locking plates versus antegrade nailing in the treatment of non-osteoporotic Neer classification 3- and 4-part fractures after a least 1 year of follow-up.

Material And Methods: Internal fixation was performed in 67 fractures (1 bilateral): 35 by locking plate (1 lost to follow-up, 1 deceased) and 32 by intramedullary nailing (2 lost to follow-up) between January 1st, 2004 and December 31st, 2010.

Total hip or knee replacement for osteoarthritis: mid- and long-term quality of life.

Objective: To compare quality of life (QOL) scores 3 and 10 years after total hip arthroplasty (THA) or total knee arthroplasty (TKA) for osteoarthritis with QOL scores in a general population, and to determine factors associated with QOL after surgery.

Methods: Data were obtained from 2 multicenter cohorts of patients with THA or TKA: 232 patients were recruited during 2003 (3-year cohort) and 221 patients were recruited during 1994 (10-year cohort). Preoperative data (QOL, radiograph results) and followup data (demographics, comorbidities, pain locations, environmental factors, and QOL) were collected.

[Optoelectronic gait analysis after metatarsophalangeal arthrodesis of the hallux: fifteen cases].

Purpose Of The Study: Degeneration of the metatarsophalangeal joint of the hallux is a frequent secondary lesion of the first ray subsequent to hallux valgus. Different surgical techniques have been proposed for cure, including metatarsophalangeal arthrodesis. Joint fusion relieves pain but sacrifices joint motion.

Do clinical presentation and pre-operative quality of life predict satisfaction with care after total hip or knee replacement?

We conducted a multicentre cohort study of 228 patients with osteoarthritis followed up after total hip or knee replacement. Quality of life and patient satisfaction were assessed by self-administered questionnaires. Patient satisfaction was the dependent variable in a multivariate linear regression model.

The value of external fixation for unstable pelvic ring injuries.

Unstable pelvic ring injuries are severe injuries, with high morbidity and mortality rates. Since 1994, the authors have been using external fixation to treat these injuries. They present the results achieved in a series of 22 cases of unstable pelvic ring injuries admitted to their institution between 1994 and 2001.

Tuberculosis of the patella.

Background: A rare case of patella tuberculosis in a 33-year-old man is presented. In the last two decades, tuberculosis has made a vigorous comeback, due mainly to large-scale migration of populations and the increasing number of immunosuppressed patients. Extrapulmonary tuberculosis accounts for less than 3% of cases, and sites like the patella are very rare.

Use of supercritical fluid extraction as a method of cleaning anterior cruciate ligament prostheses: in vitro and in vivo validation.

The process of supercritical fluid extraction (SFE) using carbon dioxide as the mobile phase is finding increasing numbers of applications in a wide variety of industries for the extraction, separation, and cleaning of materials. This study assessed the usefulness of this approach in removing surface contaminants from a knitted polyester anterior cruciate ligament (ACL) prosthesis before packaging and sterilizing the product during manufacture. The physical, dimensional, and chemical properties of SFE treated compared with commercially scoured control samples were characterized using a number of textile test methods: electron spectroscopy for chemical analysis, Fourier transform infrared spectroscopy, differential scanning calorimetry, and solvent extraction analysis.

[Current treatment of static deformities of the great toe].

The modern techniques of treatment of the hallux valgus are founded on the biomechanic and permit to give again a good function of the big toe. The authors prefer the osseous methods and specially the phalangeal and metatarsal osteotomies. It is necessary also to do a lateral release of the metatarsophalangeal joint and an exostosectomy.

[Flatfoot].

The flat foot is a very frequent cause of consultation in podology. The lesion is rapidly fixed, and osteoarthrosis appears. The diagnosis is clinical.

Evaluation of the effect of three surface treatments on the biocompatibility of 316L stainless steel using human differentiated cells.

AISI 316L stainless steel (SS) is widely used in orthopaedic implantology, although biological complications may result from its insufficient mechanical and tribological properties. In order to improve the wear and corrosion resistance as well as the hardness of 316L SS, three surface treatments, derived from those applied in mechanical engineering industries, were investigated: (1) glow discharge nitrogen implantation, (2) carbon-doped stainless steel coating sputtering and (3) low temperature plasma nitriding. Surface characterization according to the different heat treatments showed that corrosion and wear resistance were strongly improved, especially by ion implantation or carbon-doped SS coating sputtering.
