ABSTRACT
Soccer is the most popular sport worldwide, and it is associated with high injury rates, with most of these injuries occurring in the lower extremities. Particularly, in youth soccer players with immature skeleton, the physeal plate is two to five times weaker than the surrounding fibrous structures, and therefore more vulnerable to injury. The physeal plate consists of epiphyses and apophyses, with the former serving as tendon attachment sites and being subject to traction forces. There are two types of apophyseal injury: (i) apophyseal avulsion, which consists of an acute separation across the physeal plate; and (ii) apophysitis, an injury caused by chronic and repetitive contraction of musculotendon unit, leading to inflammation of the growth plate cartilage. Apophyses of the hip and pelvis are the most commonly injured in youth soccer players, due to vigorous contractions during sports activities and the fact that they tend to fuse later compared to other epiphyseal centers, making them more susceptible to injury. In this review, we will discuss the anatomy of lower limb apophyses and clinical and imaging findings of apophyseal injuries in youth soccer players, as well as briefly review treatment options and complications.
ABSTRACT
OBJECTIVE: Several anatomical parameters have been associated with increased risk of anterior cruciate ligament rupture; however, published studies provide conflicting results. The objectives of this study are to assess whether there is a relationship between anterior cruciate ligament rupture and the lateral and medial posterior tibial slopes, as well as the lateral and medial posterior meniscal slopes and posterior tibial and meniscal delta-slopes. MATERIALS AND METHODS: A retrospective case-control study was conducted in professional soccer athletes, using images from knee magnetic resonance imaging scans in athletes with clinical and radiological diagnosis of anterior cruciate ligament rupture, and control group, with no signs of ligament rupture. RESULTS: The lateral and medial posterior tibial slopes, the lateral and medial posterior meniscal slopes, and the posterior tibial and meniscal delta-slopes showed significant differences between the groups (p < 0.05). Multivariate analysis logistic regression revealed that the lateral and medial posterior meniscal slopes proved to be predictors for increased risk of anterior cruciate ligament rupture in professional soccer players. CONCLUSION: Posterior tibial and meniscal slopes and tibial and meniscal delta-slopes are related to a greater risk of rupture of the anterior cruciate ligament in professional male soccer athletes. The lateral and medial posterior meniscal slopes are predictors for ligament rupture.
