Objective: To review internal impingement of the shoulder. Design: Review article. Anatomic & Biomechanical Factors: Internal impingement is typically understood to be the impingement of the cuff on the posterior-superior labrum, with shoulder abduction and external rotation, a position seen in overhead athletes. While pinching of the cuff on the posterior labrum can be seen in normal subjects,...

Femoroacetabular impingement, also known as hip impingement, is the abutment of the acetabular rim and the proximal femur. Hip impingement is increasingly recognized as a common etiology of hip pain in athletes, adolescents, and adults. It injures the labrum and articular cartilage, and can lead to osteoarthritis of the hip if left untreated. Patients with hip impingement often report anterolat...

This is an isolated case of a giant cell tumor originating from the synovium of the hip, consistent with Pigmented Villonodular Synovitis (PVNS) and associated with concurrent Femoroacetabular Impingement (FAI). There is a paucity of literature on this condition. This case report will add to the literature on hip pathology that may be treated using arthroscopic surgery.

PURPOSE To establish if a positive impingement sign in femoroacetabular impingement (FAI) may result from entrapment of the fat pad located at the anterior head-neck junction of the upper femur. This fat pad is routinely removed before any cam lesion excision. METHODS We report a prospective study of 142 consecutive hip arthroscopies for symptomatic FAI where the aim was to remove the arthros...

Acetabular intraosseous cysts are frequently encountered in patients with dysplasia or femoroacetabular impingement. Small cysts are typically addressed by removing the cyst lining and stimulating healing via microfracture or abrasion chondroplasty. In contrast, larger cysts involving 1-3 cm(3) frequently require additional fortification with bone graft material to facilitate osseous ingrowth a...

OBJECTIVE To present our experience and preliminary results from using controlled hip dislocation to treat cam-like femoroacetabular impingement, in teenagers and young adults with sequelae of slipped capital femoral epiphysis. METHODS This was a retrospective analysis on 15 patients who were treated in a tertiary-level hospital between 2011 and 2013. The following data were collected for ana...
