Randomized Controlled Trial Clinical Trial
Surgical treatment of fracture-dislocations of the ankle joint with biodegradable implants: a prospective randomized study.
In a randomized study 43 patients with fracture-dislocations of the ankle joint were treated by open reduction and fixation with either steel or biodegradable implants. Results in both groups were favorable and the biodegradable material appears to be useful for some fracture-dislocations to obviate the need for a second operation.

A series of 16 consecutive adults with femoral shaft fractures complicated by fracture-dislocations of the ipsilateral hip joint was prospectively studied. There were 11 posterior dislocations and five central dislocations. ⋯ Although an 18.8% (3 of 16) complication rate was noted, the outcome was satisfactory for all 16 hip joints. When such complicated combined injuries are sustained, the technique described here is the most reasonable treatment.

Comparative Study
Reliability of the Glasgow Coma Scale when used by emergency physicians and paramedics.
We sought to determine the reliability of the Glasgow Coma Scale (GCS) when used by emergency physicians and paramedics. We performed a prospective sequential trial in a classroom setting, with subjects blinded to others' scoring. Nineteen university-affiliated emergency physicians and 41 professional paramedics from an urban EMS system voluntarily participated. ⋯ Intrarater reliability (r1,2) for emergency physicians was 0.66 (p < 0.01) and for paramedics was 0.63 (p < 0.01). The GCS shows statistically significant reliability (i.e., significant agreement) between emergency physicians and emergency medical technician-paramedics. It also has a significant level of intrarater reliability.

The purpose of this study was to evaluate the ability of abdominal ultrasound (US) to detect intra-abdominal injuries that required surgical repair. We therefore retrospectively reviewed 353 patients with nontrivial blunt abdominal trauma. ⋯ Accuracy was 99.4%, the positive predictive value was 100%, and the negative predictive value was 99.4% (prior probability of disease was 7.65%). We believe that abdominal US should be considered an important tool and an integral part in the work-up of major trauma victims.

Fifty-eight lower limb salvage attempts over a 10-year period were retrospectively scored using the Mangled Extremity Syndrome Index (MESI), Mangled Extremity Severity Score (MESS), Predictive Salvage Index (PSI), and the Limb Salvage Index (LSI). Primary amputations were excluded. ⋯ Although most failed limb salvage attempts could be identified early in the course of management, a significant percentage of our patients suffered prolonged reconstructive efforts. We conclude that efforts must be directed at more precisely determining the factors that aid in the decisions to terminate futile salvage efforts.
