Comparative Study
Increased neurologic complications associated with postoperative epidural analgesia after tibial fracture fixation.
A retrospective study of 63 patients with surgically treated tibial fractures was performed. The type of postoperative analgesia was compared against the type of fracture, mechanism of injury, type of fixation, adequacy of pain control, and incidence of neurologic complications. The only difference observed among all of these comparisons was that patients given postoperative epidural analgesia with local anesthetics were 4.1 times more likely to have a neurologic complication than those receiving systemic narcotics (P = 0.0496). We conclude that patients who have undergone surgical treatment of tibial plateau or shaft fractures have a significantly higher risk of developing neurologic complications when post-operative epidural analgesia is used.

A hybrid acromioclavicular joint fracture-dislocation in which an intra-articular fracture of the distal clavicle coexisted with a coracoclavicular ligament injury is described. The proposed mechanism of injury is a fall on the point of the shoulder that simultaneously drives the scapula both anteriorly and inferiorly. ⋯ The inferiorly acromioclavicular ligament was still attached to this distal clavicle fragment. The inferiorly directed force ruptured the coracoclavicular and superior acromioclavicular ligaments.

Nineteen cases of external rotation (open book) injury of the pelvis were studies retrospectively. An apparent vertical displacement of the hemipelvis was detected on anteroposterior radiographic views in association with the separation of the symphysis pubis and opening of the sacroiliac joint. This could be confused with a vertically unstable situation; however, careful examination of the radiographs revealed that the public bone on the side of injury was displaced inferiorly. ⋯ The pubic bone on the side of the sacroiliac disruption displaced inferiorly as the external rotation progressed. It is important to differentiate between the inferiorly displaced pubic bone on the side of injury in cases of external rotation injury and the superiorly displaced pubic bone on the side of injury in cases of vertically unstable pelvic injuries. This may eliminate unnecessary procedures such as skeletal traction or pinning of the sacroiliac joint.

Simple and reliable diagnostic aids need to be available for clinicians to consider sacroiliac joint dysfunction in the differential diagnosis of low back pain. The Fortin finger test was used as a means to identify patients with low back pain and sacroiliac joint dysfunction. Provocation-positive sacroiliac joint injections were used to ratify or refute the applicability of this new clinical sign for identification of patients with sacroiliac joint dysfunction. ⋯ A subset of 10 individuals underwent additional evaluation to exclude the possibility of confounding discogenic or posterior joint pain sources. All 10 patients had no indication of either discogenic or zygapophyseal joint pain generators. These results indicate that positive findings of the Fortin finger test, a simple diagnostic measure, successfully identifies patients with sacroiliac joint dysfunction.
