From 1996 to 2005, 30 hips with a diagnosis of slipped capital femoral epiphysis were treated according to the technique described. The average follow-up time was 55 months (24-96 months). Femoral head necrosis did not occur. Distribution across sexes was well balanced. Girls were 12 years old at the time of the operation and boys were 14 years old on average. Posterior displacement was measured at 30-70 degrees. In six hips there was a so-called acute on chronic slip. Two hips required revision due to screw failure, a difficulty that was addressed by the introduction of fully threaded wires. One hip had to be revised because the fully threaded wire bent. After reoperation, shortening of maximum 1 cm was seen in these three cases. In one patient with ectopic bone formation at the anteroinferior femoral neck, internal rotation in flexion is reduced by half.

The spine surgeon should be aware of the possibility of postoperative ischemia of the liver and stomach by occlusion of the celiac artery or its supplying branches. Specifically when a large correction of a kyphotic/kyphoscoliotic spine is planed, the surgeon should be alert for an appearance of a MALS.

The attitudes of the owners or managers of properties potentially supporting populations of night parrot (Pezoporus occidentalis) in western Queensland, Australia, were explored using interviews to understand whether they would be sympathetic to the species’ conservation. Eighteen interviews were carried out by a former member of the local grazing community and found a high level of support for conservation, especially if it did not unduly disrupt existing grazing management practices and there was compensation in the event property management needed to change. This included trying to limit burning and not overgrazing habitat in which the parrot might occur. It also included the cessation of wild dog baiting, which is conducted to reduce calf losses, although concern about wild dogs was deeply entrenched. While some graziers were indifferent, none were openly antagonistic to parrot conservation that might involve their property. The results suggest that collaborative management with local graziers can contribute substantially to conservation of the night parrot in the region and any fears that graziers might be antagonistic to night parrot conservation are ill-founded.

Isolated non-skeletal injuries of the cervical spine are rare and frequently missed. Different evaluation algorithms for C-spine injuries, such as the Canadian C-spine Rule have been proposed, however with strong emphasis on excluding osseous lesions. Discoligamentary injuries may be masked by unique clinical situations presenting to the emergency physician. We report on the case of a 28-year-old patient being admitted to our emergency department after a snowboarding accident, with an assumed hyperflexion injury of the cervical spine. During the initial clinical encounter the only clinical finding the patient demonstrated, was a burning sensation in the palms bilaterally. No neck pain could be elicited and the patient was not intoxicated and did not have distracting injuries. Since the patient described a fall prevention attempt with both arms, a peripheral nerve contusion was considered as a differential diagnosis. However, a high level of suspicion and the use of sophisticated imaging (MRI and CT) of the cervical spine, ultimately led to the diagnosis of a traumatic disc rupture at the C5/6 level. The patient was subsequently treated with a ventral microdiscectomy with cage interposition and ventral plate stabilization at the C5/C6 level and could be discharged home with clearly improving symptoms and without further complications.This case underlines how clinical presentation and extent of injury can differ and it furthermore points out, that injuries contracted during alpine snow sports need to be considered high velocity injuries, thus putting the patient at risk for cervical spine trauma. In these patients, especially when presenting with an unclear neurologic pattern, the emergency doctor needs to be alert and may have to interpret rigid guidelines according to the situation. The importance of correctly using CT and MRI according to both -standardized protocols and the patient's clinical presentation -is crucial for exclusion of C-spine trauma.
