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.

Does antero-lateral ankle impingement exist?

Antero-lateral ankle impingement syndrome (ALAIS) is a well-established clinical entity that is a common consequence of ankle sprains. Injury to the anterior talo-fibular ligament plays a key role in the genesis of ALAIS. Arthroscopic antero-lateral synovectomy is the standard of care.

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.

Posterior tibial tendon transfer in the spastic brain-damaged adult does not lead to valgus flatfoot.

Background: We studied the possible development of valgus flat foot after transfer of the posterior tibial tendon to the lateral cuneiform, used for surgical restoration of dorsiflexion in brain-damaged adult patients with spastic equinovarus foot.

Methods: Twenty hemiplegic patients were reviewed with a mean postoperative follow-up of 57.9 months.

[Statistical analysis of the factors that increase perioperative bleeding in trochanteric fractures].

Objective: The objective of this study was to determine the major risk factors for bleeding in patients with a pertrochanteric fracture in order to plan the transfusion strategy and to overcome the problem of post-surgical anaemia. Various factors were analysed, including the taking of anticoagulant and/or anti-platelet treatment, the type of fracture, type of anaesthesia, and the type of osteosynthesis used.

Material And Methods: A retrospective study was performed on 307 patients over 75 years old, operated on between the years 2005 and 2009.

Patient information ahead of anterior cruciate ligament reconstruction: Experience in a university hospital center.

Introduction: Patient information is the requisite first step in securing informed consent ahead of surgery, and is legally mandatory. The study hypothesis was that this information is deficient in a significant proportion of cases. This was tested on a clinical audit.

Surgery for femoroacetabular impingement using a minimally invasive anterolateral approach: analysis of 118 cases at 2.2-year follow-up.

Introduction: Treatment of femoroacetabular impingement (FAI) has progressed over time from using long incisions and dislocation to using arthroscopic surgery. Minimally invasive treatment has rarely been evaluated and a minimally invasive, anterolateral approach has not been used up to now for this indication. A prospective, on-going study was performed to evaluate surgical treatment of FAI with a minimally invasive, anterolateral approach.

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.

Accuracy of 3D reconstructions based on cone beam computed tomography.

Three-dimensional imaging of teeth will increase its impact in clinical practice if reconstructions are metrically accurate. We hypothesized that, with cone beam computed tomography (CBCT) data, three-dimensional images of teeth can be reconstructed with the same accuracy and precision as with in vitro micro-computed tomography (micro-CT) data acquisition, the current reference standard. We used a sample of CBCT and micro-CT data taken of tooth germs.

Tamponade following sternoclavicular dislocation surgical fixation.

The authors report a case of posterior sternoclavicular dislocation surgically reduced and stabilized with tenodesis, according to the Burrows technique completed by temporary wire fixation. The patient presented postoperative pericardiac tamponade appearing progressively from brachiocephalic blood vessels bleeding. Emergency drainage was surgically placed associated with removal of the material, thus curing the patient.

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.
