Coronal acetabular fractures: the anterior approach in computed tomography-navigated minimally invasive percutaneous fixation.

PURPOSE: To demonstrate the technical feasibility of the anterior approach to the coronal roof component of carefully selected acetabular fractures in computed tomography (CT)-navigated closed reduction and percutaneous fixation (CRPF). METHODS: Four patients with nondisplaced or slightly displaced coronal fractures of the acetabular roof were treated with percutaneous screw fixation. Screws were implanted over guidepins placed under CT navigation. Mean clinical and radiological follow-up was 16 months. RESULTS: All screws could be placed as intended. There were no peri- or postoperative complications. Radiological follow-up showed primary osseous union. Clinical results were excellent according to a median Merle-d'Aubigné score of 18. CONCLUSION: Nondisplaced or slightly displaced coronally oriented fractures of the acetabular roof can be treated by minimally invasive percutaneous CT-navigated fixation through an anterior approach that does not endanger the sciatic nerve. Early clinical results are encouraging. Close cooperation between trauma surgeons and radiologists and careful selection of cases is mandatory.

Posterior pelvic ring fractures: closed reduction and percutaneous CT-guided sacroiliac screw fixation.

PURPOSE: To assess the midterm results of closed reduction and percutaneous fixation (CRPF) with computed tomography (CT)-guided sacroiliac screw fixation in longitudinal posterior pelvic ring fractures. To document radiographic and CT follow-up patterns. METHODS: Thirteen patients with 15 fractures were treated. Eleven patients received a unilateral, two a bilateral, screw fixation. Twenty-seven screws were implanted. Continuous on-table traction was used in six cases. Mean radiological follow-up was 13 months. RESULTS: Twenty-five (93%) screws were placed correctly. There was no impingement of screws on neurovascular structures. Union occurred in 12 (80%), delayed union in 2 (13%), and nonunion in 1 of 15 (7%) fractures. There was one screw breakage and two axial dislocations. CONCLUSION: Sacroiliac CRPF of longitudinal fractures of the posterior pelvic ring is technically simple, minimally invasive, well localized, and stable. It should be done by an interventional/surgical team. CT is an excellent guiding modality. Closed reduction may be a problem and succeeds best when performed as early as possible.

Teaching infant CPR to mothers of cocaine-positive infants.

Cocaine abuse, a major problem in our society, has increased in women of childbearing age. Because cocaine-positive infants are at greater risk for apnea/sudden infant death syndrome (SIDS), their mothers need to be instructed in infant CPR. This study compared the use of a computerized interactive video learning system to the traditional infant CPR teaching method (lecture, video, and return demonstration) to determine the most effective method. This study indicated that mothers of cocaine-exposed infants can learn infant CPR in the immediate postpartum period and that the traditional method was found to be more effective. One unexpected positive outcome was the increase in these mothers' self-esteem.
