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.

One hundred nineteen patients suffered penetrating cardiac trauma over a 15-year period: 59 had gunshot wounds, 49 had stab wounds, and 11 had shotgun wounds. The overall survival rate was 58%. The most commonly injured structures were the ventricles. ⋯ We conclude that sternotomy provides superior exposure for cardiac repair in patients with penetrating anterior chest trauma. We feel it is the incision of choice in hemodynamically stable patients. Thoracotomy should be reserved for unstable patients requiring aortic cross-clamping, or when posterior mediastinal injury is highly suspected.

We retrospectively reviewed the medical records and cervical films, computed tomographic (CT) scans, and tomographic studies of 216 consecutive patients with cervical injuries. A trauma series of roentgenograms--a cross-table lateral (CTL), a supine anteroposterior, and an open-mouth odontoid view--was performed in 100%; CT scanning was performed in 100%; and tomography was done in 9% of cases. We determined what percentage of the patients were asymptomatic initially in the emergency department; the total numbers of fractures, subluxations, and dislocations of the cervical spine in these patients; and what percentage of the cervical injuries were not detected with the plain films. ⋯ Of these 28, 17 were intoxicated or had mild closed head injuries; however, in 11 (5%) there was no clinical clue to their cervical injury other than a known injury mechanism. Prospectively, 67% of the fractures and 45% of the subluxations and dislocations were not detected by the CTL films, and 32% of the patients, over half of whom had unstable cervical injuries, were falsely identified as having normal spines. Prospectively, the trauma series improved the sensitivity of plain films for detecting cervical injuries but still did not detect 61% of the fractures and 36% of the subluxations and dislocations, and falsely identified 23% of the patients, half of whom had unstable cervical injuries, as having normal cervical spines.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

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.
