Ultrasound-Guided Perimeniscal Injections: Anatomical Description and Feasibility Study.

Objectives: To anatomically describe the ultrasound (US)-guided perimeniscal injection technique, and evaluate its feasibility in the treatment of meniscal pain.

Methods: This work was initially undertaken in four cadaveric specimens with US-guided medial and lateral perimeniscal injection of China ink, followed by cadaveric dissection to assess injectate distribution, and potential injury to intra-articular and peri-articular structures. Then, 35 consecutive patients who underwent US-guided perimeniscal corticosteroid injection under local anesthesia for the treatment of symptomatic medial (30/35) or lateral (5/35) degenerative meniscal tear were retrospectively evaluated.

Self-incompatibility limits sexual reproduction rather than environmental conditions in an invasive water primrose.

Fruit-set and seed-set depend on environmental conditions and reproductive systems. They are important components of sexual reproductive success in plants. They also control the ecological success and adaptation of invasive plants within their non-native ecosystems.

A decision-making tool to prescribe knee orthoses in daily practice for patients with osteoarthritis.

Objective: To develop a decision-making tool (DMT) to facilitate the prescription of knee orthoses for patients with osteoarthritis (OA) in daily practice.

Methods: A steering committee gathered a multidisciplinary task force experienced in OA management/clinical research. Two members performed a literature review with qualitative analysis of the highest-quality randomized controlled trials and practice guidelines to confirm evidence concerning knee orthosis for OA.

[Sports-related concussions in youths].

Mild head trauma can be associated with concussion, defined as transient brain function impairment without radiological findings. Sports-related concussion is also reported in pediatrics (rugby, ice hockey, football, boxing, etc.).

Formulation and storage of platelet-rich plasma homemade product.

The platelet-rich plasma (PRP) is an autologous biotherapy based on platelet-healing properties. Here, we developed a simple and reproducible PRP purification protocol based on two successive centrifugations. We evaluated different centrifugation speeds and time-storage durations on the platelet quantity and quality.

[Postexercise duplex ultrasound to diagnose external iliac endofibrosis].

Arterial endofibrosis is a disease of recent discovery which concerns high-performance athletes, predominantly competitive cyclists. The preferential location is the external iliac artery. The symptoms are diverse (pain, edema, paresthesia), always linked to an effort.

Peroneus quartus and functional ankle instability.

Introduction: Physical and rehabilitation medicine physicians commonly see patients with chronic functional ankle instability. The main anatomical structures involved in ankle stability are the peroneus (fibularis) brevis and peroneus longus muscles. Several anatomical muscle-tendon variations have been described in the literature as being sometimes responsible for this instability, the peroneus quartus muscle being the most frequent.

Effect of a plaster containing DHEP and heparin in acute ankle sprains with oedema: a randomized, double-blind, placebo-controlled, clinical study.

Objective: Ankle sprains are the most frequent injuries in sport and daily life, and are usually treated with anti-inflammatory drugs or compounds that have an effect on microcirculation. The efficacy and tolerability of a novel plaster containing both diclofenac epolamine (DHEP) and heparin in the treatment of acute painful ankle sprains with oedema was investigated in a randomized, double-blind, placebo-controlled study.

Research Design And Methods: This study, carried out in 32 French medical centres, enrolled 233 patients (148 male and 86 female, aged 18-65 years) with an ankle sprain that had occurred within the previous 48 hours.

Comparative study of clinical and ultrasonographic evaluation of lateral collateral ligament sprains of the ankle.

Aim: Clinical examination is sometimes insufficient to assess the severity of lateral collateral ligament (LCL) sprain of the ankle, making it difficult to choose the most appropriate treatment. The aim of this study was to compare the assessment of clinical signs and the ultrasonographic findings in recent LCL sprain of the ankle.

Methods: This was a retrospective cross-sectional study.

Eccentric reinforcement of the ankle evertor muscles after lateral ankle sprain.

To compare two methods of ankle evertor muscle reinforcement after ankle sprain: concentric vs eccentric reinforcement. Eighteen subjects practising sport with first episode of ankle sprain. The first randomized group underwent conventional physical therapy including concentric reinforcement of the evertor ankle muscles [concentric group (CG)].

[Isokinetic dynamometer measurement of shoulder rotational strength in healthy elite athletes (swimming, volley-ball, tennis): comparison between dominant and nondominant shoulder].

Objective: To compare lateral rotator (LR) and medial rotator (MR) muscle strength of both shoulders in a sport involving asymmetrical movements (tennis), symmetrical movements (swimming), and symmetrical and asymmetrical movements (volley-ball).

Materials And Methods: Retrospective study of 42 healthy elite athletes (18 women: 14 tennis players, 19 swimmers and 9 volleyball players. We evaluated the strength of LR and MR of both shoulders by Cybex Norm isokinetic dynamometer, in the concentric mode, in the modified Davies position, at 2 different speeds (60 degrees and 180 degrees s(-1)) and analysed peak torque of LR and MR and LR/MR ratios.

[Delayed post effort muscle soreness].

Muscle intolerance to exercise may result from different processes. Diagnosis involves confirming first the source of pain, then potential pathological myalgia. Delayed-onset muscle soreness (DOMS), commonly referred as tiredness, occurs frequently in sport.

[Posture and movement analysis and sports medicine].

The use of posture and movement analysis methods has developed during the past 15 years. These methods are of special interest in the field of sport sciences and have allowed to improve the understanding of physiology of posture and movement in athletes. More recently these methods have been used in the field of sport medicine.

Combined effect of heat stress, dehydration and exercise on neuromuscular function in humans.

This study examined the combined effect of exercise induced hyperthermia and dehydration on neuromuscular function in human subjects. Six trained male runners ran for 40 min on a treadmill at 65% of their maximal aerobic velocity while wearing a tracksuit covered with an impermeable jacket and pants to impair the evaporation of sweat. These stressful experimental running conditions led the runners to a physiological status close to exhaustion.
