Five-year clinical follow-up of arthroscopically treated chronic ankle instability.

Introduction: Arthroscopic treatment of lateral ankle instability is a recent innovation. In 2014, a prospective study was initiated by the French Society of Arthroscopy demonstrating the feasibility, morbidity and short-term results of arthroscopic treatment of ankle instability.

Hypothesis: The functional results of arthroscopic treatment of chronic ankle instability found after one year were maintained in the medium term.

PT4: New arthroscopic technique for isolated reconstruction of the anterior talofibular ligament using a quadrupled plantaris tendon.

The strategy for surgical treatment of chronic ankle instability is becoming increasingly refined. In instances of isolated symptomatic non-repairable anterior talofibular ligament (ATFL) injury, there is a surgical indication for isolated ATFL reconstruction. However, we feel that the typical gracilis tendon graft is not always appropriate.

Diagnosis and treatment of tibiofibular syndesmosis lesions.

The tibiofibular syndesmosis is a fibrous joint essential for ankle stability, whence the classical comparison with a mortise. Syndesmosis lesions are quite frequent in ankle trauma. This is a key element in ankle stability and lesions may cause pain or instability and, in the longer term, osteoarthritis.

Agreement between arthroscopic and imaging study findings in chronic anterior talo-fibular ligament injuries.

Background: Imaging studies done to evaluate chronic ankle instability (CAI) often fail to accurately detail injuries to the anterior talo-fibular ligament (ATFL) and may, therefore, also fail to provide guidance for selecting the most appropriate surgical procedure. Arthroscopy is now an indispensable tool for accurately diagnosing ATFL injuries. This study looked at agreement between arthroscopy and imaging study assessments of ATFL injuries.

Arthroscopic treatment of chronic ankle instability: Prospective study of outcomes in 286 patients.

Background: Chronic ankle instability (CAI) is the main complication of ankle sprains and requires surgery if non-operative treatment fails. Surgical ankle stabilisation techniques can be roughly classified into two groups, namely, repair involving retensioning and suturing of the anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) and reconstruction using a tendon graft. Arthroscopic repair and reconstruction techniques for CAI have been introduced recently.

Arthroscopic classification of chronic anterior talo-fibular ligament lesions in chronic ankle instability.

Background: The surgical treatment of chronic ankle instability (CAI) relies chiefly on anterior talo-fibular ligament (ATFL) repair (with or without augmentation) or anatomical reconstruction with a tendon graft. Arthroscopy enables not only a complete assessment and the same-stage treatment of concomitant articular lesions, but also an accurate assessment of ligament lesions. Pre-operative imaging studies (MRI, CT, US) may fail to provide sufficient detail about chronic ATFL lesions to guide the decision between repair and reconstruction.

Modeling and determination of directionality of the kerf in epifluorescence sharp bone trauma analysis.

Characteristics of sharp bone trauma can be extremely useful to determine the origin of cut marks and to provide information regarding the context of death. Using human ribs and clavicle bones, this study analyzes the characteristics of bone kerfs made by different bladed implements, thanks to epifluorescence macroscopy. This technique, which is a nondestructive tool that uses autofluorescence of bones, documents bone damage precisely with high resolution.

Anatomic variations of the renal vessels: focus on the precaval right renal artery.

The aim of this study was to determine the prevalence of precaval right renal artery and to investigate the distribution of renal arteries and veins. We discuss a theory of development of renal vascular variants. We retrospectively reviewed 120 arterial phase contrast material-enhanced spiral computerized tomography scans of the abdomen (1- to 2-mm section thickness) performed during a two-month period.

The anconeus, an active lateral ligament of the elbow: new anatomical arguments.

Purpose: As there are a few detailed anatomical studies of the active function of anconeus muscle in stabilizing the elbow, we aimed to look for anatomical features confirming its role as an active stabilizer of the humero-ulnar joint.

Methods: Thirty fresh unembalmed elbows from 15 cadavers were dissected. We examined the anatomy, insertions, relationships and orientation of the muscle fibres of the anconeus.

Correlations between effective permeability and marrow contact channels surface of vertebral endplates.

Homeostasis of the intervertebral disc relies on nutrient supply and waste clearance through the dense capillary network that is in contact with the cartilage endplate (CEP). We developed a micro-computerized tomography (micro-CT) method to quantify the marrow contact channel surface (MCCS) with the CEP and to validate the hypothesis according to which MCCS was correlated to the effective permeability of the vertebral endplate (VEP) and influenced by the mechanical stimuli. The influence of compression loading on local vascularization was investigated.

A case of malignant primary non-Hodgkin's lymphoma in skeletal muscle treated by exclusive chemotherapy.

Malignant non-Hodgkin's lymphoma (MNHL) is a frequent tumour but a primary intra-muscular location is exceptional. Standard treatment combines wide surgical removal with chemotherapy and radiotherapy. The functional consequences of this large excision are sometimes very unsatisfactory.

Cementless modular hip arthroplasty as a salvage operation for failed internal fixation of trochanteric fractures in elderly patients.

Failure of internal fixation of trochanteric fractures requires repeat surgery in order to avoid the risks of complications affecting bedridden patients. This study was conducted to assess the results of hemi- or total hip arthroplasty with a cementless modular femoral stem, as a salvage operation following early mechanical failure of internal fixation. Twenty nine patients with a mean age of 81.

Anterolateral mini-invasive versus posterior mini-invasive approach for primary total hip replacement. Comparison of exposure and implant positioning.

Introduction: We conducted a prospective study to compare the exposure and implant positioning in primary total hip replacement through the anterolateral minimally invasive (ALMI) approach versus the posterior minimally invasive (PMI) approach.

Materials And Methods: We applied these techniques to 2 consecutive groups (33 and 43 patients, respectively) comparable preoperatively. All the patients received the same cementless stem and acetabular component.

Learning curve for a modified Watson-Jones minimally invasive approach in primary total hip replacement: analysis of complications and early results versus the standard-incision posterior approach.

We analysed the learning curve of an anterolateral minimally invasive (ALMI) approach for primary total hip replacement (THR). The first 42 THR's with large-diameter heads implanted through this approach (group 1) were compared to a cohort of 58 THR's with a 28-mm head performed through a standard-incision posterior approach (group 2). No selection was made and the groups were comparable.
