AbstractPeriarticular hardware placement can be challenging and a source of angst for orthopaedic surgeons due to fear of penetrating the articular surface and causing undue harm to the joint. In recent years, many surgeons have turned to computed tomography (CT) and other intraoperative or postoperative modalities to determine whether hardware is truly extraarticular in areas of complex anatomy. Yet, these adjuncts are expensive, time consuming, and often unnecessary given the advancement in understanding of intraoperative fluoroscopy. We present a review article with the goal of empowering surgeons to leave the operating room, with fluoroscopy alone, assured that all hardware is beneath the articular surface that is being worked on. By understanding a simple concept, surgeons can extrapolate the information in this article to any joint and bony surface in the body. While targeted at both residents and surgeons who may not have completed a trauma fellowship, this review can benefit all orthopaedic surgeons alike.

Intraoperative Localization

Abstract OBJECTIVE Exact intraoperative localization of pathologies in spinal and peripheral nerve surgery is not easily achieved. In spinal surgery, intraoperative fluoroscopy is the common method for identification of the level affected. It seldom visualizes the pathology itself and is prone to error in identifying anatomic disorders and superimposing structures. In peripheral nerve surgery, intraoperative fluoroscopy is of little value. The present technical study was conducted to evaluate the feasibility of using a preoperative computed tomography–guided needle marking system, which was previously developed for use in gynecology. The goal was to reduce intraoperative localization error and radiation exposure to patients and operating room personnel. METHODS We used a flexible hooked-wire needle marking system, which has previously been used for preoperative marking of breast lesions, to localize and tag spinal and peripheral nerve pathologies. Marking was carried out under computed tomographic control before surgery. Seven illustrative cases were chosen for this report: 6 patients with disorders of the spine and 1 patient with a peripheral nerve schwannoma. RESULTS No adverse reactions, aside from minor discomfort, were observed in this study. In all cases, the needle could be used as a reliable guide for the surgical approach and led directly to the pathology. In no case was additional intraoperative fluoroscopy needed. The level of radiation exposure to the patient as a result of computed tomography–based marking was similar to or less than that encountered in conventional intraoperative x-ray localization. Radiation exposure to the operating room personnel was eliminated by this method. CONCLUSION Preoperative marking of spinal level or peripheral nerve pathologies with a flexible hooked-wire needle marking system is feasible and appears to be safe and useful for neurosurgical spinal and peripheral procedures.

Areas Of Concern

Background: Postpartum is an important phase of life after childbirth. It needs to be highly important as in terms of health in future life. This time brings lots of complications with it. Lots of aspects need to be looked after as the care of the new mom is essential to bring back her stamina and strength. Objective: The objective of this review article is to explore the heeding power hidden in nature for returning back to the mothers to the pre-pregnancy state. There are various areas of concern after postpartum to heal up the body overall, such as to heal up the uterus, providing galactagogues, nutritives, maintenance of hormones and restoring back the strength and tone of the abdomen. Materials and Methods: A literature search has been done on the various herbs, which fulfill the various desired aspects to be looked after post pregnancy. Results: There are various herbs present in nature, regarding their hidden potential still the awareness is not up to the mark. This review highlights the various plants which have been proven to be useful in dealing the post-pregnancy issues. They deal with all the aspects of complications and issues occurring post pregnancy. They heal the uterus which has undergone so many types of changes, maintains the balance of hormones back, besides providing nutrition and increasing the production of milk, they also restore back the tone and strength of the walls of the abdomen. Conclusion: These herbs are full-fledged with the phytoconstituents that heal the whole system after delivery. The need of present time is to take patiently these as the source of medicines regularly under medical supervision to overcome the various concerned problems of post pregnancy.

AbstractDead bodies exhibit a variable range of changes with advancing decomposition. To quantify intracorporeal gas, the radiological alteration index (RAI) has been implemented in the assessment of postmortem whole-body computed tomography. We used this RAI as a proxy for the state of decomposition. This study aimed to (I) investigate the correlation between the state of decomposition and the season in which the body was discovered; and (II) evaluate the correlations between sociodemographic factors (age, sex) and the state of decomposition, by using the RAI as a proxy for the extent of decomposition. In a retrospective study, we analyzed demographic data from all autopsy reports from the Institute of Forensic Medicine of Zurich between January 2017 to July 2019 and evaluated the radiological alteration index from postmortem whole-body computed tomography for each case. The bodies of older males showed the highest RAI. Seasonal effects had no significant influence on the RAI in our urban study population with bodies mostly being discovered indoors. Autopsy reports contain valuable data that allow interpretation for reasons beyond forensic purposes, such as sociopolitical observations.

Lipiodol Marking

Abstract OBJECTIVES This study aimed to evaluate the safety and reliability of percutaneous computed tomography (CT)-guided lipiodol marking for undetectable pulmonary lesions before video-assisted thoracic surgery (VATS). METHODS We retrospectively analysed the cases of CT-guided lipiodol marking followed by VATS in 9 institutes from May 2006 to March 2018. Lipiodol (0.2–0.5 ml) was percutaneously injected closely adjacent to undetectable pulmonary lesions with computed-tomography guidance. Lipiodol spots were identified using C-arm-shaped fluoroscopy during VATS. We grasped the lipiodol spots, including the target lesions, with ring-shaped forceps and resected them. RESULTS Of 1182 lesions, 1181 (99.9%) were successfully marked. In 1 case, the injected lipiodol diffused, and no spot was created. Of the 1181 lesions, 1179 (99.8%) were successfully resected with intraoperative fluoroscopy. Two lipiodol spots were not detected because of the lipiodol distribution during the division of pleural adhesions. The mean lesion size was 9.1 mm (range 1–48 mm). The mean distance from the pleural surface was 10.2 mm (range 0–43 mm). Lipiodol marking-induced pneumothorax occurred in 495 (57.1%) of 867 cases. Of these, chest drainage was required in 59 patients (6.8%). The other complications were 19 (2.2%) cases of bloody sputum, 3 (0.35%) cases of intravascular air, 1 (0.12%) case of pneumonia and 1 (0.12%) case of cerebral infarction. There were no lipiodol marking-induced deaths or sequelae. CONCLUSIONS Preoperative CT-guided lipiodol marking followed by VATS resection was shown to be a safe and reliable procedure with a high success rate and acceptably low severe complication rate.
