Bone-tendon and bone-ligament interface

Reconstruction or repair of ligaments and tendons to bone, following injury, to improve joint function is a very common surgical procedure in orthopedics. The most common surgical ligament reconstruction in humans is anterior cruciate ligament (ACL) reconstruction. Because ACL is not amenable to repair after tear, replacement of the ligament using autograft or allograft tissue is currently the treatment of choice for young and active patients. On the other hand, surgical reattachment to bone is the most reliable treatment in case of rotator cuff tendon tears. Tendon grafting or repair to bone is performed during hand, foot, and ankle surgery. Nowadays, ACL reconstruction and repair of rotator cuff tendon tears are the most commonly performed surgical procedures for soft tissue injuries in orthopedics. © 2014 Springer-Verlag London.

Ecological Contexts in Adolescent Pregnancy: The Role of Individual, Sociodemographic, Familial and Relational Variables in Understanding Risk of Occurrence and Adjustment Patterns

Adolescent pregnancy appears today as an intricate tapestry where different dimensions interact. In our study we examined the associations between individual, sociodemographic, familial, and relational variables and their impact in the occurrence of pregnancy and adolescents’ adjustment to it. Participants were Portuguese pregnant and non-pregnant adolescents (N = 833). Ecological contexts were characterized, and individual and relational adjustment (depressive symptoms and quality of life; perceived quality of relationship with significant others – parents, romantic partner and friends) were evaluated. Differences between the ecologies of adolescents in both groups were identified. Familial and relational variables were significantly associated with both the risk of pregnancy and more difficulties in adjustment. Implications for preventive intervention are discussed
