Spine update. Administrative databases in spine research.
The use of administrative health care databases for the storage and retrieval of information is increasing. The data collection, entry, and collation follows a predictable process for hospital admissions. Many conclusions have been drawn from research performed using administrative databases. These conclusions can have significant and important implications for patients, providers, and society at large, to the extent that such data inform participants in the current health care policy debate. In an effort to better understand the significance of conclusions drawn from studies that rely on electronic administrative databases as their source of information, the present report addresses the process, strengths, weaknesses, and future plans for the use of administrative databases in spine research.

Quality of data regarding diagnoses of spinal disorders in administrative databases. A multicenter study.
The purpose of the present study was to evaluate the accuracy of data regarding diagnoses of spinal disorders in administrative databases at eight different institutions. The records of 189 patients who had been managed for a disorder of the lumbar spine were independently reviewed by a physician who assigned the appropriate diagnostic codes according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). The age range of the 189 patients was seventeen to eighty-four years. The six major diagnostic categories studied were herniation of a lumbar disc, a previous operation on the lumbar spine, spinal stenosis, cauda equina syndrome, acquired spondylolisthesis, and congenital spondylolisthesis. The diagnostic codes assigned by the physician were compared with the codes that had been assigned during the ordinary course of events by personnel in the medical records department of each of the eight hospitals. The accuracy of coding was also compared among the eight hospitals, and it was found to vary depending on the diagnosis. Although there were both false-negative and false-positive codes at each institution, most errors were related to the low sensitivity of coding for previous spinal operations: only seventeen (28 per cent) of sixty-one such diagnoses were coded correctly. Other errors in coding were less frequent, but their implications for conclusions drawn from the information in administrative databases depend on the frequency of a diagnosis and its importance in an analysis. This study demonstrated that the accuracy of a diagnosis of a spinal disorder recorded in an administrative database varies according to the specific condition being evaluated. It is necessary to document the relative accuracy of specific ICD-9-CM diagnostic codes in order to improve the ability to validate the conclusions derived from investigations based on administrative databases.

Administrative databases' complication coding in anterior spinal fusion procedures. What does it mean?
STUDY DESIGN: A review of a cohort of 310 consecutive patients who underwent anterior spinal fusion was performed to evaluate the accuracy of hospital ICD-9-CM complication coding. OBJECTIVES: To better understand the clinical significance of conclusions suggested by studies that rely on electronic administrative databases for their data source. SUMMARY OF BACKGROUND DATA: Despite their availability, there have been no studies to date that have evaluated the accuracy of ICD-9-CM administrative databases as they relate to the actual clinical experience in spinal procedures. METHODS: A physician and a research technician independently reviewed the primary medical records for the occurrence of complications. This data was compared with the hospital-acquired ICD-9-CM coded complications. RESULTS: The physician reviewer identified 152 complications in 119 patients, with 32 different types of complications. The research abstracter identified 175 complications in 130 patients, with 34 different types of complications identified. Hospital ICD-9-CM coding identified 105 complications in 80 patients, including only 11 different ICD-9-CM codes. Overall, 27% of ICD-9-CM complication codes were listed as "unspecified or unclassified complications, reactions, or misadventures," and contained no meaningful clinical information. Cardiac and pulmonary complications were over-estimated and wound infections and genitourinary and gastrointestinal complications were underestimated by ICD-9-CM coding. CONCLUSIONS: Studies of complications of spinal procedures using data derived from hospital ICD-9-CM complication codes may be intrinsically flawed because the data available to researchers from these electronic databases may be inaccurate.

The surgical and medical perioperative complications of anterior spinal fusion surgery in the thoracic and lumbar spine in adults. A review of 1223 procedures.
STUDY DESIGN: A retrospective review of 1223 thoracic and lumbar anterior spinal fusions was performed from 1969 through 1992. OBJECTIVES: To document the incidence and specific types of perspective complications related to anterior spinal fusions. SUMMARY OF BACKGROUND DATA: Despite the increased use of anterior spinal surgery, there has been little documentation of the specific types and frequencies of the complications associated with its use. METHODS: All Minnesota Spine Center patients age 18 years or older who had anterior spinal fusions between the levels of T1 and S1 from August 1969 to June 1992 were reviewed for the occurrence of perioperative complications. Surgical approach and technique and associated comorbidity was recorded. RESULTS: The risk of a complication was increased for patients over age 60 years, for women, and for patients with multiple preexisting health problems. Serious complications, such as death (0.3%), paraplegia (0.2%), and deep wound infection (0.6%) were rare. The complication rate for complications that were directly attributed to the anterior spinal surgery was 11.5%. CONCLUSIONS: Anterior spinal fusion surgery is a safe procedure and can be used with confidence when the nature of a patient's spinal disorder dictates its use. Complications are often approach specific.

Segmental spinal dysgenesis. A disorder different from spinal agenesis.
We reviewed the clinical and roentgenographic findings, treatment, and results for seventeen patients (six male and eleven female) who had segmental spinal dysgenesis, a disorder frequently confused with, but distinct from, lumbar and lumbosacral agenesis. The average age at the time of presentation to the Minnesota Spine Center or the Gillette Children's Hospital was two and a half years (range, newborn to twenty-one years), and the average duration of follow-up was eight years (range, five months to twenty-two years). At the time of the diagnosis, eight patients had neurological deficits: seven had a neurogenic bladder and four had weakness of the lower extremities. An average of 2.6 procedures (range, one to five procedures) was needed to obtain a solid fusion. Decompression of the stenotic canal was performed in ten patients, and it was followed by an improvement in neurological function in two of them. A solid fusion of the spine, arrest of the progressive kyphosis, and stabilization of neurological function were obtained in all patients. We recommend early anterior and posterior arthrodesis in patients who have segmental spinal dysgenesis, as the progressive kyphosis that inevitably develops often results in neurological deficits.

Pemberton osteotomy for residual acetabular dysplasia in children who have congenital dislocation of the hip.
We reviewed the results for fifty-two hips in forty-two patients who had had a Pemberton pericapsular osteotomy between 1968 and 1984 as treatment for residual acetabular dysplasia of the hip. The average age of the patients at the time of the osteotomy was four years. The average duration of follow-up was ten years. At the time of the most recent follow-up, forty-two of the fifty-two hips had a rating of Severin class IA, an essentially normally developed hip. The results of the Pemberton osteotomy were unpredictable if there had been necrosis of the femoral head (without infection) preoperatively. We believe that the Pemberton osteotomy is a safe, effective procedure for the treatment of acetabular dysplasia in patients who have congenital dislocation of the hip.

Subtle injuries of the Lisfranc joint.
In fifteen patients, a subtle injury of the Lisfranc joint (tarsometatarsal articulation) was found. The lesion was defined as a diastasis of two to five millimeters between the bases of the first and second metatarsals, as seen on anteroposterior radiographs. There often was a long delay between injury and diagnosis. Eight patients were treated with a below-the-knee cast only, three had treatment with a cast and then tarsometatarsal arthrodesis, two had no initial treatment but later had arthrodesis, and two had open reduction and internal fixation. The duration of follow-up ranged from two to thirteen years after the diagnosis. There was no correlation between the severity of the diastasis and the patient's functional result. Marked disability and pain persisted in seven patients, and six of them had flattening of the longitudinal arch. Maintenance of the longitudinal arch usually was associated with a better functional outcome. When a patient has a subtle injury of the Lisfranc joint, weight-bearing lateral radiographs of both feet are needed to identify flattening of the longitudinal arch. Such radiographs should be made routinely in the evaluation of all injuries of the foot that may involve the Lisfranc joint.

Human bite wounds.
Human bite injuries, as innocuous as they may initially appear, may result in severe impairment. With a better understanding of the anatomy, microbiology, mechanism of injury, and clinical presentation, early diagnosis and the institution of appropriate therapy may minimize the morbidity commonly associated with human bite infections of the hand.

Triple innominate osteotomy for acetabular dysplasia.
Fifty-six hips in 44 patients that underwent triple innominate osteotomy were reviewed. Average follow-up was 7 years (range 2-12 years). Patients were evaluated with regard to any postoperative pain and any improvement in function and as to whether they would recommend the procedure. Improvement in pain and function was considered good in 53 hips. Three hips were considered failures. Forty-two of 44 patients strongly recommended the procedure. Two patients would not recommend the procedure. In all, 94% of patients had improvement in both pain and function and recommended the operation.
