Avaliação da retroversão da cabeça do úmero em jogadores de handebol

Abstract: OBJETIVOS: Avaliar a retroversão da cabeça do úmero em jogadores de handebol e sua relação com a movimentação do ombro. MATERIAIS E MÉTODOS: Foram avaliados 17 jogadores profissionais por meio de exame físico e avaliação radiográfica, para se determinar o ângulo de retroversão e, sua relação com o arco de movimento. O mesmo foi realizado num grupo controle. RESULTADOS: A diferença entre a média do ângulo de retroversão da cabeça do úmero do membro dominante e não dominante foi de 3,06°. Entre eles, aqueles que… Show more

“…Keywords -Baseball; Shoulder; Joint Range of Motion of these athletes: hypertrophy and shortening of the posterior capsule, lengthening of the anterior capsule, and increase in retroversion of the head of the humerus (3) . Bach and Goldberg (4) and Morgan (5) suggest that insufficient contraction of the musculature of the posterior region of the shoulder (posterior portion of the deltoid muscle, supra-and infraspinal muscles, teres minor, trapezius, and biceps muscle of the arm) in the deceleration phase of the pitching motion leads to cyclic stress in the joint capsule, particularly in the posterior inferior region, causing it to contract, resulting in glenohumeral internal rotation deficit (GIRD).…”

“…Repeated throwing associated with the abovementioned alteration leads to a relative increase in length of the anterior inferior portion of the joint capsule, leading to a gain in lateral rotation (GLR) (7) . Another hypothesis for the gain in lateral rotation in these athletes is the increase in humeral retroversion, which can occur in the shoulders of athletes whose skeletal structures are still developing (3) . Due to the abovementioned adaptations, the dominant shoulder movement in pitchers is altered, with an increase in lateral rotation and a decrease in internal rotation with the shoulder abducted 90°( 7) (Figure 1).…”

“…The humeral torsion or humeral head retroversion (UHR) is an anatomical feature that exists only in monkeys and hu-mans; it is defined, in anatomy, as the spiral movement of this bone, stabilizing at the end of growth with the closure of the humerus proximal epiphyseal line. 3 4 It is known that UHR is characterized by increased external rotation range of motion (ROM) of and decreased internal rotation of the shoulder at 90˚ abduction. 5 …”

“…In athletes practicing throwing sports such as handball, abduc-tion and external rotation take place, generating adaptations both of soft tissue and bone structure. 4 Injuries that occur in these sports are related especially to movement. 1 The loss of internal rotation (medial) of the dominant limb compared to the non-dominant limb of the pitcher is called GIRD (Glenohumeral Internal Rotation Deficit) 6 7 and has been related to an adaptive contracture of the posterior capsule in pitchers.…”
