Currently, the standard method of plate/screw internal fixation of this type of fracture has yielded only fair results. A new technique of retrograde intramedullary nailing through the femoral component using the GSH supracondylar nail is described in this report. A review of four series in which more than 50 patients were treated using the GSH nail indicates a significant difference in bone grafting (10% versus 75%), delayed union (7.2% versus 50%), nonunion (1.9% versus 10%), and surgical revision (0 versus 10%) compared to plate/screw fixation of similar fractures. The findings in this review indicate that the GSH supracondylar nail provides excellent biomechanical stability in these complex fractures, resulting in minimal complications and allowing early return of the patient to functional activities.</p>","PeriodicalId":79846,"journal":{"name":"Contemporary orthopaedics","volume":"31 4","pages":"231-8"},"PeriodicalIF":0.0,"publicationDate":"1995-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21035768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although vertebral osteomyelitis represents only 2-4% of bone infections, the consequences are often grave and disabling, even fatal, when untreated. A series of 23 cases is reported in which patient records were reviewed to determine the etiology and appropriateness of diagnosis and management. Information on treatment and follow-up after discharge was obtained from outpatient progress notes, records from subsequent hospital admissions, and telephone interviews of patients. Pyogenic vertebral osteomyelitis was diagnosed by positive needle or open biopsy tissue cultures, positive blood cultures in the appropriate clinical setting, or diagnostic histopathology. Staphylococcus aureus was grown from 75% (15/20) of patient cultures, Escherichia coli from 15%, and Staphylococcus epidermidis from 10%. Overall, 87% (20/23) of these patients were disease-free at follow-up.
