Trauma and co-morbidity--a pilot study.

AIMS: To study the adult trauma patient population at the Auckland Hospital in order to determine the age distribution of trauma, the prevalence and importance of co-morbid conditions and any effect of the latter on the length of stay in the hospital. METHODS: Data were collected on 78 consecutive patients admitted to the Auckland Hospital under the Trauma team between December 1999 and January 2000. Data were collected by interviewing the patient, as well as reviewing patient's medical notes and the Trauma Registry. RESULTS: The prevalence of co-morbidities was 14.7%. No co-morbidity was found below the age of 40 years, but the prevalence of co-morbidity increased with age. The average length of stay for patients with no comorbidities and an Injury Severity Score (ISS) >15 was 19 days while for those with co-morbidities was 24.5 days--an increase of 29%. CONCLUSION: This pilot study has found that a significant number of trauma patients being admitted to Auckland Hospital have a pre-existing co-morbid condition that may alter their length of stay. It is an important issue that warrants further investigation, in order to devise a more accurate prognostic scoring system.

Lumbar transverse process fractures--a sentinel marker of abdominal organ injuries.

Fractures of lumbar vertebrae may be associated with abdominal organ injuries. Lumbar transverse process fractures are commonly thought of as minor injuries compared with body, pedicle and lamina fractures. To determine the significance of transverse process fractures as opposed to other lumbar vertebral fractures in relation to abdominal organ injury, a retrospective study was performed. One hundred and ninety-one patients with lumbar spine fractures were reviewed. One hundred and thirty-five (71%) of these had non-transverse process (NTP) fractures only (including vertebral body, pedicle, or spinous process fractures). Fourty-two patients (22%) had transverse process fractures only. Fourteen patients (7%) had both transverse process and NTP fractures. Twenty (48%) of the 42 patients with transverse process fractures had abdominal organ injuries identified. This was a significantly (P<0.05) higher rate than for the patients with NTP fractures, eight of 135 (6%). Patients with transverse process fractures and abdominal organ injuries had a median injury severity score (ISS) of 29 compared with a median ISS of 17 for patients with NTP fractures and abdominal organ injuries. If a transverse process has been fractured, there is likely to have been very large forces involved in the incident. The data strongly suggest that lumbar transverse process fractures should not be thought of as minor injuries but regarded as a significant marker for abdominal organ injuries and should alert the doctor caring for the injured patient of the high probability of these injuries.

Recurrence of gout after total knee arthroplasty.

The existence of gout in a total knee arthroplasty (TKA) may be more common than is currently recognized. We report 2 cases of acute recurrence of gout in knees after TKA, 1 with coexistent infection.
