Objectives: previous studies investigating the ability of isokinetic strength ratios to predict hamstring injuries in soccer players have reported conflicting results. Hypothesis: determine if are able injury occurring during season professional players.Study Design: case-control study; Level evidence: 3. Methods: from 2001 2011, 350 tests were performed 136 at beginning season.Fifty-seven suffered that followed tests.These compared with 79 uninjured players.The bilateral concentric ratio...

BACKGROUND: The rapid spread of the SARS-CoV-2 infection required general confinement measures reducing or even preventing sport practice, which was a risk detraining in athletes. In adolescents, is poorly known as well its prevention by home-exercises. This article aimed to assess effects COVID-19 on young high-level soccer players despite multimodal training program conducted at home.METHODS: Twenty-five elite players, aged 14, were included perform physical exercises home during...

Case Hoffa fractures, uncommon injuries of the femoral condyle, sometimes involve both condyles, forming bicondylar typically from high-velocity trauma. We describe a 17-year-old male with an open conjoined fracture and patellar incarceration following road traffic accident. Emergency treatments included debridement, irrigation, cannulated screw fixation. Postoperative care involved controlled range-of-motion exercises specialized rehabilitation. Conclusion Despite its rare severe nature,...

The majority of anterior cruciate ligament (ACL) injuries occur during non-contact mechanisms. Knowledge the risk factors would be relevant to help prevent athletes' injuries. We aimed study associated with ACL in a population athletes after reconstruction. From cohort 307 athletes, two populations were compared according or contact mechanism injury. Gender, age and body mass index (BMI) reported. Passive knee alignment (valgus extension), laxity (KT-1000 test), isokinetic strength measured...

Hamstring strain injuries frequently occur during professional soccer practice. Low hamstring strength represents an intrinsic modifiable risk factor but cutoffs of isokinetic knee ratios are controversial to predict in players. We aimed accordance with ratios. Bilateral, conventional, and functional were calculated 194 players at the beginning 15 consecutive seasons. 36 presented a moderate 158 not injured. The different compared right left limb uninjured population. Different usual tested:...

Anterior cruciate ligament reconstruction (ACLR) using hamstring tendon (HT) graft aims to stabilise the knee, but it may bring some complications like anterior knee (AKP) pain that can have consequences on functional aspect of this surgery. The aim study was compare isokinetic strength and outcomes between patients with without AKP following an ACLR HT during first-year post-surgery. Three hundred thirty subjects operated by were included in our retrospective cohort divided into two groups:...

Arthrofibrosis is a devastating complication after Anterior Cruciate Ligament reconstruction (ACLr) characterized by muscle weakness secondary to an arthrogenic inhibition process. The loss of knee isokinetic strength due may be more important arthrofibrosis, compared ACLr population with no complication. deficit [Limb Symmetry Index (LSI) at 60 and 180°/s angular speed] was measured 4, 7 12 post-operative months. Knee function, return running sport were evaluated. A comparison the...

Circumferential skin defects of the fingers are a technical challenge. Although rare, their management should respect tissue organization and functional abilities. We report two cases circumferential defect. Management used individually tailored "wrap-around" flaps taken from hallux. The sample concerned proximal cutaneous sheath first toe neurovascular pedicle inter-metatarsal space. Nail pad were spared. Both had complex defect finger, involving neuro-vascular pedicle. Postoperative...

Neurogenic thoracic outlet syndrome (NTOS) is the most frequent form of TOS. It may affect both sides, but specific complementary exams are lacking. We aimed to evaluate duplex scanning results in a group patients with unilateral or bilateral NTOS and no clinical vascular signs, referred for rehabilitation. performed retrospective observational study symptoms. Subclavian vessels were assessed by scanning. Compressions considered case >50% increased decreased blood flow. A total 101 met...

Patellar tendinopathy (PT) in professional volleyball players can have an impact on their careers. We evaluated the of this pathology specific population terms isokinetic strength and jumping performances. Thirty-six male (mean age: 24.8 ± 5.2) performed knee assessments, single-leg countermovement jumps one leg hop test. They filled out Victorian Institute Sport Assessment-Patella (VISA-P) score. Two groups were assessed: “PT group” (n = 15) “control 21). The VISA-P score was lower PT group...

We aimed at estimating the agreement between Medicap" (photo-optical) and Radiometer• (electrochemical) sensors during exercise transcutaneous oxygen pressure ( tcp02) tests. Our hypothesis was that although absolute starting values (tcp02rest: mean over 2 minutes) might)e different, tcpOTchanges time minimal value of decrease from rest (DROPmin) results shall be concordant two systems. taneously, one each system on chest, buttock calf.Seventeen probes disconnected tcp02rest DROPmin were...

Neurogenic thoracic outlet syndrome (NTOS) is a chronic painful and disabling condition. Patients complain about upper-limb paresthesia or weakness. Weakness has been considered one of the diagnostic criteria NTOS, but objective comparisons to healthy controls are lacking. We compared grip key pinch strengths between NTOS patients controls. Grip strength was evaluated with hydraulic hand dynamometer gauge. All completed QuickDASH. included prospectively 85 73% female 27% male. The mean age...

We describe the preliminary results of a novel two-stage reconstruction technique for extended femoral bone defects using an allograft in accordance with Capanna embedded vascularized fibula graft induced membrane according to Masquelet technique. performed what we refer as “Capasquelet” surgery diaphyseal loss at least 10 cm. Four patients were operated on this technique: two tumors and traumatic septic context minimum follow up one year. Consolidation both sides, when achieved, occurred...

After anterior cruciate ligament reconstruction (ACLR), a progressive process is followed from rehabilitation to the return sport including crucial step known as running. Return running (RTR) can be predicted by an isokinetic knee strength assessment at 4 months post-surgery. All patients who had primarily undergone ACLR with hamstring autograft procedure between 2010 and 2020 were included in this study. Four after surgery, evaluated using test. Patients monitored until 6th month...

Chronic exertional compartment syndrome (CECS) is characterized by pain occurring during physical activity. As clinical examination not sufficient to diagnose it, intracompartmental pressure (ICP) measure used for CECS confirmation. Numerous signs are reported but their diagnosis predictive ability has never been studied. We aimed determine if the 12 classically of CECS. performed a single-centre retrospective cohort study on patients referred suspicion. Patients were asked run treadmill....

Objectives: Hamstring muscle injury prediction by isokinetic strength ratios is low but could result from the method—depending either on use of limbs or sportsmen as references. We aimed to establish a predictive model including unilateral and bilateral calculated dominant, nondominant, right, left limb in injured uninjured professional soccer players. Design: Cohort study. Setting: Soccer team French Professional Premier League. Patients: Ninety-one Interventions: Isokinetic was...
