Ankle dislocations are orthopedic emergencies that require immediate treatment to avoid neurovascular impairment. They are usually accompanied by one or more comminuted fractures of the ankle mortis. In rare circumstances, such as high-energy trauma, the ankle dislocations may not be accompanied by concomitant malleolar fractures and, thus, are named "pure ankle dislocations". We presented a very rare and interesting case of an open medial dislocation of the ankle without associated fracture in an 18-year-old man with no known predisposing risk factors. The patient was admitted to the emergency department after sustaining a catastrophic trampoline accident resulting in severe inversion of the right ankle. The patient was treated with an external fixator and was mobilized early in the post-surgical course. Despite initial presentation that revealed lack of posterior tibial pulse, the post-surgical course was uneventful, with full functional recovery and joint mobility. The primary goals of treatment are immediate reduction of the joint and relief of neurovascular stress. External fixation is a prompt, fairly easy treatment that one should keep in mind in pure ankle dislocations. Nonetheless, ligamentous restoration and early mobilization were the key elements as seen in our case for full functional recovery.

Vascular leiomyoma is a benign, usually solitary tumor arising from the tunica media of the vein. It can occur anywhere in the body wherever smooth muscle is present. These masses are commonly found in the uterus, urogenital tract and gastrointestinal tract but also less commonly in the extremities. They occur more often in the lower extremities than the upper extremities. Females are more affected than males and are generally seen in the third and fourth decades of life. We present magnetic resonance imaging, and histopathologic features of two pathology proven subcutaneous vascular leiomyomas of the hand and lower leg.

The purpose of this article is to quantify changes in thickness of the ligamentum flavum (LF) associated with motion of the cervical spine and to compare the thickness of the LF at each cervical level using kinetic magnetic resonance imaging (kMRI). Two hundred fifty-seven symptomatic patients (129 men; 128 women) underwent kMRI in neutral, flexion, and extension positions. Midsagittal images were digitally marked and electronically analyzed by spine surgeons. Thickness of LF in the cervical region from C2–3 to C7–T1 was measured in all three positions. LF at C7–T1 was significantly thicker than C2–3 to C6–7 in neutral, flexion, and extension positions (p < 0.05). LF was significantly thicker in extension than in flexion at C3–4 to C6–7. LF thickness increases with extension and decreases with flexion. LF is uniquely thick at C6–7 and at C7–T1 in the extension position, which may predispose these levels to cord compression syndromes and associated neuropathies.

Adrenal hemorrhage following blunt abdominal trauma is extremely rare. Most of the lesions are unilateral and right sided. Although often asymptomatic, life-threatening adrenal insufficiency may develop in the bilateral adrenal gland hemorrhage. Isolated adrenal injuries are very rare. They are often associated with other organ injuries. The mortality rates of patients range from 7% to 32%. In this report, we present the computed tomography and magnetic resonance imaging findings of unilateral adrenal hemorrhages in two patients with a history of fall from a height.
