Intermediate-term outcome of cervical spinal cord-injured patients older than 50 years of age.

STUDY DESIGN: This study retrospectively reviewed the intermediate-term clinical outcome of patients who were 50 years of age or older at the time they experienced their cervical spinal cord injury. OBJECTIVES: To establish reasonable expectations for the functional outcome in the older patient with cervical spinal cord injury. BACKGROUND DATA: The long-term morbidity and mortality of large groups of patients with spinal cord injury have been reported. The specific functional ability, disposition, morbidity, and mortality of this group of older patients injured after 50 years of age, however, have been less well defined. METHODS: Forty-one consecutive patients older than 50 years of age at the time of cervical cord injury were studied, and functional abilities, independence, need for assistance in activities of daily living, disposition, morbidity, and mortality were assessed. All patients had more than 2 years of follow-up examinations (mean, 5.5 years) by the same spine injury service. RESULTS: There were 13 complete and 28 incomplete cervical cord lesions. The mean age of the patients at follow-up examination was 67.5 years. The average follow-up period was 5.5 years after injury. None of the patients with complete cord injury improved, and all required extensive care. Twenty-one (80%) of 26 of the patients with incomplete cord injury were able to ambulate with some assistance. Nineteen of 26 patients had independent or near-independent abilities with activities of daily living. Twenty (77%) of 26 were able to return home. All patients with complete cord injury (13 of 13) had died by the time of the follow-up visit. Seventy-seven percent (10 of 13) of this patient group had died within the first year. Those surviving lived an average of 3.5 years after their injury. Fourteen of 28 patients with incomplete cord injury (50%) had died by the time of the follow-up visit. Six (43%) of the 14 deaths were attributed to complications of their spinal cord injury. CONCLUSION: The functional outcome of the person older than 50 years with a complete cervical cord injury is poor. Of the 14% who survived the first year, all required extensive attendant care, and no neurologic improvement was seen. The patient with an incomplete cord injury has an overall good outcome regarding ambulation and returning to home.

Burst fractures of the second through fifth lumbar vertebrae. Clinical and radiographic results.

Fifty-five patients who had sustained a burst fracture of the lumbar spine were followed for a mean of seventy-nine months (range, twenty-four to 192 months) after the injury. Thirty patients had been managed non-operatively with a short period of bed rest followed by protected mobilization. The remaining twenty-five patients had been managed operatively: eight, with posterior arthrodesis with long-segment hook-and-rod fixation; eight, with posterior arthrodesis with short-segment transpedicular fixation; six, with posterior arthrodesis and instrumentation followed by anterior decompression and arthrodesis; and three, with anterior decompression and arthrodesis. Thirty-six patients had been neurologically intact at the time of presentation and had remained so throughout the follow-up period. No neurological deterioration or symptoms of late spinal stenosis were seen. Isolated partial single-nerve-root deficits resolved regardless of the method of treatment. Patients who had had a complete single or a multiple-nerve-root paralysis seemed to have benefited from anterior decompression. Although the anatomical results as seen on the most recent radiographs were superior for the group that had been managed operatively with long posterior fixation or anterior and posterior arthrodesis, the most recent pain scores and the functional outcomes were similar for all treatment groups. At the latest follow-up evaluation, some loss of spinal alignment was noted in the patients who had been managed with short transpedicular fixation; the alignment at the most recent follow-up examination was comparable with that in the patients who had been managed non-operatively. For the patients who had had non-operative treatment, we were unable to predict the deformity at the time of follow-up on the basis of the initial diagnostic radiographs. The clinical outcome was not related to the deformity at the latest follow-up evaluation. On the basis of the results of our study, we recommend non-operative treatment for patients who do not have neurological dysfunction or who have an isolated partial nerve-root deficit at the time of presentation. For patients who have a multiple-nerve-root paralysis, anterior decompression is indicated.

Gelfoam-induced acute quadriparesis after cervical decompression and fusion.

STUDY DESIGN: Case report. OBJECTIVE: To acknowledge a potential serious complication of Gelfoam use in enclosed space. SUMMARY OF BACKGROUND DATA: The gelatin sponge has been used for hemostasis in spine surgery. Its complication rate is very low, but it has the potential for compression of vital tissues when left next to the spinal cord within an enclosed space. METHOD: Case report. RESULTS: Retained Gelfoam sponges were found in an enclosed space next to the spinal cord. These expanded and compromised the spinal cord. CONCLUSION: There is potential for expansion of the Gelfoam sponge in enclosed spaces after spinal surgery. There is the possibility of neurologic compromise in these cases. Gelfoam should be removed.

Early outcome in cervical spinal cord injured patients older than 50 years of age.

STUDY DESIGN: This study retrospectively reviewed consecutive spinal cord injured patients older than 50 years of age. OBJECTIVE: This study established reasonable expectations for the early clinical outcome of cervical spinal cord injured patients greater than 50 years of age. SUMMARY OF BACKGROUND DATA: Previous studies of cervical spinal cord injuries have concentrated on long-term morbidity and mortality. Little data has been reported on the early clinical outcome during rehabilitation. METHODS: Forty-two consecutive patients older than 50 years of age at the time of cervical cord injury were reviewed. Data was collected from the time of injury to discharge from rehabilitation (< 4 months) and included morbidity, mortality, and disposition of the patient. RESULTS: There were 15 complete and 27 incomplete cervical cord lesions. Forty-five percent were caused by falls, 42% by motor vehicle accidents. Serious associated morbidity was 81% in complete cord injuries and 34% in incomplete lesions. Overall mortality was 23%. Complete cord injury mortality rate was 60% in this age group. All patients over 65 years of age with complete cord injuries died. CONCLUSIONS: Incomplete cervical cord lesions have the best prognosis for return to home and a functional lifestyle. Complete cervical cord injuries in patients older than 50 years of age have a 60% mortality rate. Complete cervical cord injuries in patients over 65 years have a poor prognosis for survival.

The use of a grommet bone liner for flexible hinge implant arthroplasty of the great toe.

Press-fit titanium grommets were developed to shield flexible hinged silicone implants used for arthroplasty of the radiocarpal, metacarpophalangeal, and metatarsophalangeal joints. Since 1985, 179 titanium circumferential grommets were used in 90 first metatarsophalangeal joints with excellent, pain-free, functional results and favorable bone response around the implant stems and at the bone-grommet interface. There were no complications due to particulate reactivity, implant fracture, or grommet fracture. The use of circumferential titanium grommets appears to be a safe and effective method to improve the long-term durability of flexible hinge implant arthroplasty of the first metatarsophalangeal joint.
