Isolated anterior dislocation of the radial head (case report).

We report the case of an isolated post traumatic radial head dislocation in a 5 year old child. Clinical examination and the X ray results allow the diagnosis which can be unnoticed. The reduction by external maneuvers avoids the surgical treatment which remains the gold standard for chronic dislocation.

A giant gluteal lipoblastoma in a 24-month-old girl: A case report.

INTRODUCTION AND IMPORTANCE: Lipoblastomas are rare benign tumors that arise from embryonic white fat and almost always occur in babies and children. CASE PRESENTATION: Here, we report a case of a giant gluteal lipoblastoma in a 24-month-old girl that was successfully treated via complete resection. CLINICAL DISCUSSION: The gluteal location as in this case is an exceptional location. These tumors generally are benign, and there have been no reports of metastasis. Local recurrence can occur, particularly with lipoblastomatosis, when excision is incomplete. Surgical resection is the treatment of choice. The goal is always complete resection with negative margins, but this can be difficult to obtain with lipoblastomatosis. No spontaneous resolution or reduction of lipoblastoma has ever been reported, and a recurrence rate of 14 % and 25 % is reported in cases of incomplete excision. CONCLUSION: Lipoblastoma is a benign neoplasm of immature fat tissue occurring in infants. The gluteal region location is relatively rare. Imaging, especially MRI, is helpful in diagnosis and preoperative evaluation. An adequate pathological examination could bring huge benefits. Total surgical resection is the treatment of choice. Subtotal resection and "wait and see policy" may be discussed for highly risky intervention.

Bilateral acetabular fractures (case report).

INTRODUCTION AND IMPORTANCE: Bilateral acetabular fractures are very rare. They are usually seen in the context of multiple trauma patients. This type of fracture poses a problem and difficulty in therapeutic management, sometimes resulting in serious sequelae and significant morbidity. CASE PRESENTATION: We report a rare case of bilateral simultaneous acetabular fracture in an adult, forty-seven years old man due to a road accident. CLINICAL DISCUSSION: Bilateral acetabular fractures are very rare. While bilateral acetabular fracture most frequently occur due to automobile accidents, other mechanism can be responsible for this injury as well. Furthermore, bilateral acetabular fractures are frequently associated with other lesions of the surrounding bones or tissues. Surgery is the most suitable treatment in most cases. The development of osteoarthritis is the most common complication of acetabular fracture and is directly related to the post-operative reduction obtained. Heterotopic ossifications are a complication associated with acetabular fracture. In acetabular fracture, the primary objective of surgical treatment is anatomical reduction of the fracture that will determinate the future of hip. CONCLUSION: The treatment goal of acetabular fracture is anatomic or near anatomic reduction of the articular surface. The risk of osteonecrosis is mostly related to the initial injury and time to reduction.
