Article Synopsis
- The study investigates femoroacetabular impingement (FAI) among 120 professional male football players in Spain and compares their hip X-ray findings to a control group of 80 healthy individuals without significant sports activity.
- Results show that a significant percentage (61.6%) of players exhibited Cam-type deformity, compared to only 11.6% in the control group, along with notable occurrences of herniation pits (11.6%) and os acetabuli (13.3%).
- The findings suggest that top-level football players have a higher prevalence of certain hip deformities, indicating the potential impact of rigorous athletic participation on their hip health.
Background: The possibility of using a bone-tendon quadriceps tendon graft and platelet rich plasma (PRP) injection to enhance healing capability, to solve the defect created by stump retraction in chronic Achilles tendon ruptures was studied in a series of 8 patients.
Methods: A series of 8 patients studied prospectively and followed for more than 24 months is presented. Results were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) score, and evaluating pain, level of activity, footwear restrictions, and satisfaction.
Background: Large glenoid defects are a difficult reconstructive problem for shoulder surgeons. The purpose of this study was to determine the complications, rate of healing, and functional results of glenoid bone grafting in primary or revision surgery with reverse shoulder arthroplasty.
Methods: We retrospectively reviewed 23 patients with glenoid bone loss who underwent primary or revision surgery using a glenoid bone graft with a minimum follow-up of 2 years.
Background: Prospective studies on injuries in martial arts competition are scarce, especially those involving young practitioners, but the upsurge of children and adolescents taking part in organized training and competition in these sports requires clarification of the injury risk that they represent for youths.
Hypothesis: Top-level karate competition for young adolescents (cadets, or 14- to 15-year-olds) has a low injury rate and can be safely promoted.
Study Design: Descriptive epidemiological study.

The aim of this paper is to document the injury rate in high-level modern competitive karate after a change of competition rules was implemented in the year 2000, and to compare it with the injury rate found before the rules were changed. A prospective recording of the injuries resulting from 2,762 matches in three consecutive World Karate Championships (representing 7,425 min of active fighting) was performed, and compared with the results from 2,837 matches from the three last World Karate Championships (representing 7,631 min of active fighting) held before the change of competition rules. In total, 497 injuries were recorded, with an incidence of 0.
