(13) Bilateral hip ultrasound (LOGIQ General Imaging, GE Healthcare) was used to confirm any diagnosis of cam or pincer impingement and to evaluate the structural integrity of the acetabular labrum. Using the convex ultrasound probe, the presence of cam or pincer signs was assessed while performing the anterior impingement test (dynamic examination).

Rarely, open reduction may be required in failed cases of closed reduction either due to buttonholing of the femoral head through the hip capsule or due to infolding of the acetabular labrum. [2],[6],[11] Open reduction was not required in our series.
In addition, there was a complex tear of the anterior and anterosuperior acetabular labrum (Figure 1).
The acetabular labrum is a triangular fibrocartilaginous structure that forms a horseshoe-shaped attachment to the acetabular rim, which connects the acetabulum to the underlying transverse acetabular ligament [Figure 1]a.[sup][1] Up to 90% of symptomatic patients with developmental dysplasia of the hip (DDH) are found to combine with lesions of acetabular labrum.[sup][2] The most common presentations of the acetabular labrum lesions are hypertrophy, laceration, and/or cyst formation.[sup][3],[4] Nevertheless, a unique hip joint condition is observed recently in several symptomatic DDH patients [Figure 1]b.
The procedure also decreases the complications of hip arthroscopy such as neurovascular trauma during traction or portal placement, and iatrogenic damage to the articular cartilage and acetabular labrum when introducing instruments.[sup][8]
