Surgical treatment of complex tibial plateau fractures by closed reduction and external fixation. A review of 32 consecutive cases operated

Abstract Complex tibial plateau fractures are a challenge in trauma surgery. In these fractures it is necessary to anatomically reduce the articular part of the fracture and to obtain stable fixation. The aim of this study is to review the results of a surgical technique consisting of fluoroscopic closed reduction and combined percutaneous internal and external fixation. Thirty-two complex tibial plateau fractures in 32 patients were included. Twenty-one fractures were closed, 4 were open Gustilo grade I, 3 were Gustilo grade II and 4 were Gustilo grade III. The mean age was 37.8 years (range 21–64 years). Surgery was performed with patients in transcalcaneal traction and the knee flexed at 30° was used. Through a 1-cm incision centred over the tibial metaphysis of the tibia, a 3.2-mm hole was drilled in the antero-medial tibial aspect. The tibial plateau fracture fragments were elevated using either 1 or 2 curved Kirschner wires under fluoroscopy to control the reduction. Then the fragments were fixed with 2 cannulated AO screws inserted through small incisions into the medial aspect of the tibial plateau. Knee rehabilitation started postoperatively. Weight bearing started after 8–12 weeks depending upon the radiographic appearance. All external fixators were removed in outpatient facilities. All patients were clinically and radiographically evaluated at a mean follow-up of 48 months (range 38–57 months). Clinical results were evaluated according to the Knee Society clinical score. Average healing time was 24 weeks (range 18–29 weeks). In 1 patient a non-union occurred. This patient was treated with open reduction and plate fixation. In 2 patients a varus knee deformity occurred and a surgical correction was performed. There were no surgical complications. Mean knee range of motion was 105° (range 75–125°) and mean Knee Society clinical score was 89. Twenty-five results were scored as excellent, 4 good, 2 fair and 1 poor. Using this technique there is limited soft tissue damage and virtually no periosteum damage to the fracture fragments. However anatomical reconstruction of the joint can be obtained. Furthermore knee rehabilitation can be started immediately after surgery. We think that these factors were responsible for the optimal clinical long-term results.     

Boerhaave’s syndrome: Primary repair vs. esophageal resection—Case reports and meta-analysis of the literature

Boerhaave’s syndrome is a life-threatening disease with a high mortality. With regard to the heterogeneity of treatment strategies, no comparative studies exist and recommendations remain controversial. Seventeen cases of Boerhaave’s syndrome operated on between 1989 and 2000 at our hospital were reviewed retrospectively to compare the time period between perforation and diagnosis, and the morbidity and mortality among the different treatment options. In addition, we conducted a meta-analysis of the literature including all series containing five or more patients and compared the findings with our own data. Our patients with a perforation history of less than 12 hours showed significantly fewer signs of sepsis compared to patients with a history of more than 12 hours. In a comparison of patients with primary repair vs. patients treated with esophageal resection or an exclusion operation, no differences were found. In the literature, patients with a long period of perforation (more than 24 hours) were treated more often with an esophageal resection than patients with primary repair. In cases of Boerhaave’s syndrome, primary suturing of the esophageal perforation should be reserved only for those patients presenting within 12 hours after perforation. In all other cases, depending on the extent of the tissue damage, a two-stage esophageal resection with cervical esophagostomy and gastrostomy is recommended as the safest treatment.

Prenatal lead exposure in relation to gestational age and birth weight: A review of epidemiologic studies

Although the adverse effect on pregnancy outcomes at high levels of lead exposure in the workplace has been recognized for years, there is uncertainty regarding the impact of exposure at the lower community exposure levels commonly encountered today. This review summarizes the epidemiologic literature and discusses pertinent methodologic issues and possible sources of interstudy variation. The authors conclude that prenatal lead exposure is unlikely to increase the risk of premature membrane rupture but does appear to increase the risk of preterm delivery. Whether prenatal lead exposure decreases gestational age in terms of infants is unclear. Prenatal lead exposure also appears to be associated with reduced birth weight, but results vary in relation to study design and degree of control for confounding. Adjustment for gestational age, a possible confounder of the birth weight-lead exposure association, did not yield clearer results.
