Manejo actualizado de las fracturas costales / Current management of rib fractures

RESUMEN Las fracturas costales son la lesión más frecuente en los traumatismos torácicos. La fijación de las fracturas ha estado dirigida clásicamente al volet costal. En los últimos años se han extendido las indi caciones a las fracturas múltiples desplazadas aun sin volet. Se consideran asimismo otras indicaciones de osteosíntesis menos frecuentes. La neumonía y contusión pulmonar graves que requieren asisten cia respiratoria mecánica son consideradas contraindicaciones para la fijación quirúrgica. La primera semana es el momento óptimo para su realización. Diversos dispositivos de fijación se han ideado; las placas de titanio son las más utilizadas. La osteosíntesis costal ofrece a los pacientes una recuperación más rápida con menor estadía hospitalaria y en cuidados críticos, así como mejor funcionalidad respi ratoria y menor dolor en el corto y largo plazo.

ABSTRACT Rib fractures are the most common injuries in chest trauma. Fracture fixation has been traditionally performed in flail chest patients. Over the past years, the indication has been extended to multiple, severely displaced non-flail pattern fractures. Other less common indications for osteosynthesis have also been considered. Severe pneumonia and lung contusion requiring mechanical ventilation are considered contraindication for surgical fixation. The optimal timing for the intervention is the first week. Several devices have been developed for fracture fixation; titanium plates are the most commonly used. Rib fixation offers patients a more rapid recovery with shorter length of hospital stay and of intensive care unit stay with improved respiratory function and pain management in the short and long term.

Osteosíntesis de múltiples fracturas costales desplazadas en un paciente con tórax batiente / Osteosynthesis of multiple displaced costal fractures in a patient with flail chest

El tratamiento de las fracturas costales debe ser individualizado de acuerdo con la severidad de las lesiones y a la magnitud del trauma. El objetivo de esta investigación es presentar un caso donde se utilizaron láminas de titanio, en un paciente con fracturas múltiples de las costillas. Se reporta el caso de un paciente con múltiples fracturas costales de forma lineal y paralelas de los arcos costales con un tórax batiente, que llega al cuerpo de guardia con dolor torácico moderado y disnea. Aunque aún no existe suficiente evidencia científica a favor de los métodos de fijación costal, se realizó la fijación con láminas de titanio logrando la estabilidad de la pared, aliviando el dolor, mejorando la mecánica ventilatoria y logrando su rápida reincorporación a la sociedad(AU)

The treatment of costal fractures should be individualized according to the severity of the injuries and the magnitude of trauma. The objective of this investigation is to present a case where titanium plates were used in a patient with multiple rib fractures. We report the case of a patient with multiple rib fractures of a linear and parallel shape of the costal arches with a swinging thorax, who arrives the emergency room with moderate chest pain and dyspnea. Although there is still not enough scientific evidence that favors the costal fixation methods, the fixation with titanium plates was performed, achieving the stability of the wall, relieving pain, improving the ventilatory mechanics, and achieving the patient's quick reincorporation to the society(AU)

Fracturas costales simétricas asociadas a tos / Symmetrical rib fractures associated with chronic cough: report of one case

Cough may be associated with complications such as syncope, urinary incontinence, pneumothorax, and less frequently, pulmonary hernia and costal fractures. Chronic cough is a cause of rib fractures and when they occur it is likely to affect more than one rib. We report a 53 year-old obese male in treatment with enalapril 10 mg for hypertension with a dry cough lasting five months. He consulted for bilateral chest pain and a Chest X ray examination showed symmetrical fractures in the seventh left and right ribs. Enalapril was discontinued, cough and pain subsided in two weeks.

Analysis of 163 rib fractures by imaging examination / 法医学杂志

OBJECTIVE@#To explore the applications of imaging examination on rib fracture sites in forensic identification.@*METHODS@#Features including the sites, numbers of the processed imaging examination and the first radiological technology at diagnosis in 56 cases of rib fractures from 163 injuries were retrospectively analyzed.@*RESULTS@#The detection rate of the rib fractures within 14 days was 65.6%. The initial detection rate of anterior rib fracture proceeded by X-ray was 76.2%, then 90.5% detected at a second time X-ray, while the detection rate of CT was 66.7% and 80.0%, respectively. The initial detec- tion rate of rib fracture in axillary section proceeded by X-ray was 27.6%, then 58.6% detected at a second time X-ray, while the detection rate of CT was 54.3% and 80.4%, respectively. The initial detection rate of posterior rib fracture proceeded by X-ray was 63.6%, then 81.8% detected at a second time X-ray, while the detection rate of CT was 50.0% and 70.0%, respectively.@*CONCLUSION@#It is important to pay attention to the use of combined imaging examinations and the follow-up results. In the cases of suspicious for rib fracture in axillary section, CT examination is suggested in such false X-ray negative cases.

Application of spiral CT 3D reconstruction of rib fracture in clinical forensic practice / 法医学杂志

OBJECTIVE@#To assess the clinical application of spiral CT 3D reconstruction in forensic diagnosis of rib fracture.@*METHODS@#Thirty-five cases of rib fractures were collectively studied by X-ray, regular CT scan, and adoptive 3D reconstruction with spiral CT.@*RESULTS@#Clear and stereoscopic images of rib fractures without interference of the surrounding soft tissue were obtained in all of 35 cases examined.@*CONCLUSION@#Spiral CT 3D reconstruction could be a valuable means in forensic diagnosis of rib fracture.

Applicational study of 3D reconstruction with spiral computed tomography in evaluation of anatomical complicated bones fracture / 法医学杂志

OBJECTIVE@#To investigate forensic diagnosis application of three-dimentional reconstruction with spiral computed tomography in fracture of anatomical complicated bones.@*METHODS@#Selected eleven patients of bone fracture who were examined with SCT 3D and conventional X-ray examination. The location, number and characteristics were observed and analyzed.@*RESULTS@#In all of eleven patients with bone fractures, X-ray examination could detect thirty-four rib fracture, one scapula fracture, two nasal fracture, one metacarpal bone incomplete fracture and one left tibia-fibula fracture, one pubis fracture. While there were forty-seven rib fracture, one scapula smash fracture, one nasal fracture with obvious displacement and eliminate one misplace, one left tibia-fibula obsolete fracture and one sacroiliac joint dislocation, one No 5 lumbar vertebrae pedicle of vertebrae arch fracture. Combining 3D reconstruction images, coronary and sagittal reconstruction images could show clearly the fracture line, location of fracture, number of fracture, displacement and recovery.@*CONCLUSION@#3D reconstruction technique of SCT is a very useful examination method in the objective forensic diagnosis of anatomical complicated bones fracture, it excels the routine X-ray examination.

CT rendering and mechanical analysis for rib fracture inextricable on X-ray chest film in legal medical practice / 法医学杂志

OBJECTIVE@#To explore an approach of CT rendering and mechanical analysis for rib fracture that was inextricable on X-ray film in legal medical practice.@*METHODS@#17 cases with rib fracture undetermined on X-ray chest film in legal medical practice underwent CT scans. The thin slices (0.75 mm or lmm) of images were reconstructed with smooth and sharp kernel. The multiplanar reformatted images along rib and surface shaded display were obtained to investigate rib fracture.@*RESULTS@#All rib fractures were accurately displayed by CT scan and MPR images along rib. The torque that caused rib fracture was divided presumably into vertical and rotary types. The two kinds of rib fracture, composed of vertical and rotary type, were proposed.@*CONCLUSION@#CT scan with thin slice and MPR images can definitely reveal the rib fracture unresolved on X-ray film in legal medical practice. The proposition of two kinds of torque will be help avoid misunderstanding acute rotary type of rib fracture as old healed one.
