Sports participation can be an integral part of adolescent development with numerous positive short and long-term effects. Despite these potential benefits very high levels of physical activity, during skeletal maturation, have been proposed as a possible cause of cam-type femoroacetabular impingement (FAI). The influence of physical activity on the developing physis has been previously describ...

The normal value of alpha angle is controversial. The aim of this study was to compare the alpha angle in asymptomatic volunteers versus patients who had undergone surgery for symptomatic cam-type femoroacetabular impingement (FAI) and determine a diagnostic cut-off value for symptomatic cam impingement. This is a diagnostic test study. Cases were defined as those patients who had undergone sur...

This is a retrospective review of two adult siblings with osteogenesis imperfecta (OI) type III (according to Sillence classification), who sustained a spontaneous femoral neck fracture and subsequent nonunion. The diagnosis of OI in these two patients was made based on clinical, radiological and genetic findings. The fracture was most likely caused by femoroacetabular impingement secondary to ...

Femoroacetabular impingement causes pain in the hip in young adults and may predispose to the development of osteoarthritis. Genetic factors are important in the aetiology of osteoarthritis of the hip and may have a role in that of femoroacetabular impingement. We compared 96 siblings of 64 patients treated for primary impingement with a spouse control group of 77 individuals. All the subjects ...

Background: Femoroacetabular impingement (FAI) is pain due to shape mismatch at the hip joint commonly affecting young athletes, and there are 2 main types depending on which bone has underlying deformity: cam (femoral) pincer (acetabular). Hip arthroscopy an invaluable technique in sports surgeon repertoire, a need for comprehensive tutorial that elucidates best practices nuances. Indications:...

Groin problems in sports can be multifactorial and often a team approach between orthopaedic, general surgeons is required for both diagnosis and treatment. Both clinical disciplines can be the first point of contact for athletes looking for medical advice. Good communication between the members of a medical team looking after an athlete is essential and is not helped by the use of confusing te...

OBJECTIVES Femoroacetabular impingement is proposed to cause early osteoarthritis (OA) in the non-dysplastic hip. We previously reported on the prevalence of femoral deformities in a young asymptomatic male population. The aim of this study was to determine the prevalence of both femoral and acetabular types of impingement in young females. METHODS We conducted a population-based cross-sectio...
