Demographic trends in the occurrence of injury and improvements in the early management of spinal trauma are changing the long-term profile of patients with spinal cord injuries. More patients are surviving the initial injury, and proportionately fewer patients are sustaining complete injuries. While preventive efforts to reduce the overall incidence of spinal cord injury are important, a number of steps can be taken to minimize secondary injury once the initial trauma has occurred. ⋯ The Third National Acute Spinal Cord Injury Study investigators concluded that methylprednisolone improves neurologic recovery after acute spinal cord injury and recommended that patients who receive methylprednisolone within 3 hours of injury should be maintained on the treatment regimen for 24 hours. When methylprednisolone therapy is initiated 3 to 8 hours after injury, it should continue for 48 hours. In addition to the adoption of the guidelines of that study, rapid reduction and stabilization of injuries causing spinal cord compression are critical steps in optimizing patients' long-term neurologic and functional outcomes.

Rupture of the distal biceps tendon occurs most commonly in the dominant extremity of men between 40 and 60 years of age when an unexpected extension force is applied to the flexed arm. Although previously thought to be an uncommon injury, distal biceps tendon ruptures are being reported with increasing frequency. The rupture typically occurs at the tendon insertion into the radial tuberosity in an area of preexisting tendon degeneration. ⋯ The patient with a chronic rupture may benefit from surgical reattachment, but proximal retraction and scarring of the muscle belly can make tendon mobilization difficult, and inadequate length of the distal biceps tendon may necessitate tendon augmentation. Postoperative rehabilitation must emphasize protected return of motion for the first 8 weeks after repair. Formal strengthening may begin as early as 8 weeks, with a return to unrestricted activities, including lifting, by 5 months.

ReviewAnesthesia and analgesia for the ambulatory management of fractures in children.
The goal of anesthesia in the ambulatory management of fractures in children is to provide analgesia and relieve anxiety in order to facilitate successful closed treatment of the skeletal injury. Numerous techniques short of general anesthesia are available. These methods include blocks (local, regional, and intravenous), sedation (conscious and deep), and dissociative anesthesia (ketamine sedation). ⋯ Sedation with inhalation agents, such as nitrous oxide, and parenterally administered narcotic-benzodiazepine combinations, are not region-specific and are suitable for patients over a wide range of ages. Ketamine sedation is an excellent choice for children less than 10 years old. With any technique, proper monitoring and adherence to safety guidelines are essential.

ReviewSurgical treatment of acetabular fractures in elderly patients with osteoporotic bone.
The incidence of acetabular fractures in the elderly has recently shown a marked increase due to the combination of greater longevity for the population as a whole and a relative decrease in the incidence of alcohol-related trauma in younger adults. The compromised physiologic reserve and the diminished healing capacity of the typical elderly patient have an adverse effect on the potential for a favorable clinical outcome. The presence of osteopenic bone or degenerative arthritis and the effects of previous radiation therapy to the hip and pelvis hamper diagnostic imaging and the utility of some treatment alternatives that were designed primarily for younger patients. ⋯ The feasibility of acute total hip arthroplasty rests on the use of newly developed techniques for minimally invasive stabilization of the acetabular fracture with cables and the application of morselized or structural autograft harvested from the femoral head. Whichever surgical method is chosen, the objective is rapid mobilization of the patient on a walker or crutches. Late complications that may occur after nonoperative or operative treatment include posttraumatic arthritis, nonunion, wound infection, and heterotopic bone formation.

ReviewExtremity fractures in the patient with a traumatic brain injury.
Extremity fractures are common in patients with traumatic brain injuries (TBIs). These injuries are often inadequately treated and occasionally are completely missed due to the unique problems inherent to the TBI patient. However, appropriate evaluation of the TBI patient allows prompt diagnosis and optimal treatment of extremity fractures. ⋯ Upper extremity fractures are often associated with peripheral nerve injuries. Heterotopic ossification is common, especially about the elbow and hip. Contrary to prevalent belief, fracture healing is not necessarily accelerated in the TBI patient; hypertrophic callus, myositis ossificans, and heterotopic ossification occur frequently and are often misperceived as accelerated healing.
