Alpha Angle Values Predict the Severity of Hip Chondral Damage in Patients With Cam-Type Femoroacetabular Impingement Syndrome: A Systematic Review and Meta-analysis.

Purpose: To assess the role of alpha angle (AA) in predicting the severity of hip chondral damage in patients with cam-type femoroacetabular impingement (FAI) syndrome.

Methods: Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines, a systematic review was performed to summarize and critically appraise studies analyzing the prognostic capability of AA values in predicting the severity of intraoperatively evaluated hip chondral damage in patients with cam-type FAI syndrome. The risk of bias was assessed through the Quality In Prognosis Studies tool.

CrossFit-Induced Rhabdomyolysis in a Brazilian Coach: A Case Report.

CrossFit is a high-intensity physical activity modality that, despite its numerous health benefits, poses a risk of exercise-related injuries. The rare but serious complication of exertional rhabdomyolysis is a good example. There are few case reports describing this condition, and to the best of the author's knowledge, this is the first published case of CrossFit-induced rhabdomyolysis reported in Brazil - one of the most influential countries in the world of CrossFit.

Diagnostic Capability of Intra-Articular Injections for Femoroacetabular Impingement Syndrome: A Systematic Review.

Objective: To review and critically appraise available literature concerning the diagnostic capability of intra-articular injections for femoroacetabular impingement (FAI) syndrome.

Design: Systematic review.

Setting: N/A.

Correlation between psychological status, revised Müller AO classification and patient-reported outcomes: a prospective cohort analysis.

Introduction: The impact of psychological status on clinical outcomes is valued in several medical conditions, but rare attention is given to it in orthopedic trauma. We aimed to assess the correlation between psychological status, fracture severity and patient-reported outcomes in fractured patients needing urgency surgical treatment.

Materials And Methods: We prospectively followed 139 consecutive patients undergoing urgency surgical treatment of a lower/upper limb fracture.

Are visual assessments of the single-leg squat valid to be used in clinical practice? A systematic review of measurement properties based on the COSMIN guideline.

Objective: Evaluate the discriminative and convergent validity of visual scales for the assessment of movement quality in the single-leg squat.

Methods: Searches performed in CINAHL, Cochrane, Embase, PubMed, SPORTDiscus and Web of Science databases. Studies evaluating discriminative and convergent validity of movement quality visual assessments in single-leg squats were included.

Does response to preoperative intra-articular anesthetic injections predict outcomes of femoroacetabular impingement syndrome?

Introduction: Some patients with femoroacetabular impingement syndrome (FAIS) who undergo surgery do not show satisfactory outcomes. Reliable tests that can inform prognosis of FAIS surgery are needed for optimized indications and contraindications to surgery. We aimed to review and critically appraise available literature on the capability of patient response to preoperative intra-articular anesthetic injections (PIAI) to predict post-surgical outcomes in patients with FAIS.

Tensor fascia latae and gluteal muscles myoelectric responses to increasing levels of hip medial rotation torque.

Medial hip rotation is typically attributed to the tensor fascia latae (TFL) and lateral rotation, to the gluteus maximus. However, experimental studies in cadavers suggest that the TFL lacks a moment arm for medial rotation and that the gluteus maximus may act as hip medial rotator depending on the hip flexion angle. In order to address this contradictory thinking, we measured the myoelectric activity of TFL, gluteus medius and gluteus maximus (superior portion, GMaxS, and inferior portion, GMaxI) for increasing levels of medial rotation torque applied to the hip.
