Uncommon Variant of Type II Monteggia Fracture with Concomitant Distal Humeral Fracture.

Monteggia fracture-dislocation, a common injury sustained by pediatric population, is a rare entity in adults. It was first observed by Giovanni Battista Monteggia and later classified by Bado into 4 groups. The term "Monteggia equivalent or variant" was introduced to describe certain injuries with similar radiographic pattern and biomechanism of injury. Since then various types and their variants have been described in the literature. We present a complex fracture pattern in a 55-year-old male not previously described in the literature along with its treatment modality and favorable outcome.

Literature review and clinical presentation of bilateral acetabular fractures secondary to seizure attacks.

Central acetabular fracture dislocation is usually caused by high-energy external trauma. However, 26 cases that occurred as a result of a seizure attack appeared in the literature from 1970 to 2007, with the seizure attacks themselves caused by many different factors. In this setting, the central acetabular fracture not caused by direct trauma might initially remain unnoticed leading to a delayed diagnosis. In some cases, this may lead to death as a result of massive blood loss. We here present a case of bilateral central acetabular fracture dislocation as a result of a seizure attack.

False aneurysm of the external iliac artery caused by aseptic loosening and migration of a cemented cup.

A 79 year old woman with bilateral hip replacements presented with severe left thigh swelling, and life threatening hypovolemic shock. After adequate resuscitation, an angio CT scan of her pelvis showed a false aneurysm of the external iliac artery in proximity to a loose pegged cemented cup. A pelvic X-ray 6 years prior to presentation had revealed a medialized high riding pegged cemented cup with a loose cemented stem. Vascular reconstruction followed by revision of the left THA was necessary.
