Context:A tourniquet is a device that is used frequently in most orthopaedic surgeries but this routine device can lead to serious complications so we decided to review and declare it for safe instruction and use.Evidence Acquisition:We searched the word “tourniquet” in PubMed and Google and reviewed all full text English articles and abstracts of non-English articles. In addition, we read all the reference pages of articles to find the new references.Results:The use of tourniquet in orthopedic surgery can lead to serious but rare complications that can be prevented by its correct knowledge and use.Conclusions:At present, there is not enough evidence to discontinue the routine uses of tourniquets.
Avoidance of tourniquet use does not decrease the time to union or nonunion or the infection rate after plating of tibial fractures, but it is associated with a decrease in the patient's pain perception in the postoperative period.
Background:Tendon transfer for radial nerve paralysis has a 100 years history and any set of tendons that can be considered to be useful has been utilized for the purpose. The pronator tress is used for restoration of wrist dorsiflexion, while the flexor carpi radialis, flexor carpiulnaris, and flexor digitorum superficialis are variably used in each for fingers and thumb movements. The present study was a retrospective analysis, designed to compare three methods of tendon transfer for radial nerve palsy.Materials and Methods:41 patients with irreversible radial nerve paralysis, who had underwent three different types of tendon transfers (using different tendons for transfer) between March 2005 and September 2009, included in the study. The pronator teres was transferred for wrist extention. Flexor carpi ulnaris (group 1, n=18), flexor carpi radialis (group 2, n=10) and flexor digitorum superficialis (group 3, n=13) was used to achieve finger extention. Palmaris longus was used to achieve thumb extention and abduction. At the final examination, related ranges of motions were recorded and the patients were asked about their overall satisfaction with the operation, their ability, and time of return to their previous jobs, and in addition, disabilities of the arm, shoulder and hand (DASH) Score was measured and recorded for each patient.Results:The difference between the groups with regard to DASH score, ability, and time of return to job, satisfaction with the operation, and range of motions was not statistically significant (P>0.05). All of the patients had experienced functional improvement and overall satisfaction rate was 95%. No complication directly attributable to the operation was noted, except for proximal interphalangeal joint flexion contracture in three patents.Conclusion:The tendon transfer for irreversible radial nerve palsy is very successful and probably the success is not related to type of tendon used for transfer.
Background:Tibial fracture without concomitant fibular fracture is an injury that has long attracted notice for the fact that it sometimes heals cleanly, other times causes various problems when the bone does not heal, or misaligns. In this randomized clinical trial, we assessed two treatment modalities plating and intramedullary nailing for treatment of closed, noncomminuted tibial fractures with intact fibulae.Materials and Methods:During the three year period, 1470 patients with leg fractures were treated and out of which, 114 were eligible to enter the study. Of the eligible patients, 73 were recruited to enter the trial, and ultimately 69 of these were followed for at least one year. The patients were randomized into two groups, one of which was treated by plating of the fracture, the other group by intramedullary nailing, both of which are standard surgical procedures. The primary variables that influenced the outcome of the procedures in both treatments were the duration of surgery, the amount of bleeding, the time to union, the need to repeat surgery to achieve union, the need to remove a device, and patients’ complaints about pain or discomfort in the limb.Results:One case of nonunion occurred in the group treated with intramedullary nailing and one of the patients in this group developed late, deep infection in the screws location, which was resolved by screw removal (P = 0.285 and P = 0.478, respectively). In both groups the tibial fractures achieved union in about 4 months, though the intramedullary group underwent more operations to achieve union (dynamization was performed in 4 patients, representing 12.1% of the patients in this group, P = 0.047). During the followup period, the incidence of implant removal (after union) was not statistically significant between the two groups: two patients (6.1%) in the intramedullary group and four patients (11.1%) in the plate group (P = 0.675) had implants removed. Of the other studied variables, the difference between the two groups was statistically significant only with regard to patients’ complaints of pain in the limb and the number of individuals with knee pain (in both cases, P = 0.001). In the intramedullary group, 18 patients had no complaints (54.4%) and 13 complained of knee pain (39.4%), while in the plate group 29 had no complaints (80.6%).Conclusion:Based upon the findings of the present study, both the methods studied are suitable treatments for closed noncomminuted isolated tibial fractures, but the patients in whom intramedullary nails are used are more likely to require additional surgeries to achieve union, and probably will have more complaints of pain in their limbs or knees.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
