Traffic in the operating room during joint replacement is a multidisciplinary problemBackground: Door openings disrupt the laminar air flow and increase the bacterial count in the operating room (OR). We aimed to define the incidence of door openings in the OR during primary total joint arthroplasty (TJA) surgeries and determine whether measures were needed and/or possible to reduce OR staff traffic.
Methods:We recorded the number of door openings during 100 primary elective TJA surgeries; the OR personnel were unaware of the observer's intention. Operating time was divided into the preincision period, defined as the time from the opening of surgical trays to skin incision, and the postincision period, defined as time from incision to dressing application.
Results:The mean number of door openings during primary TJA was 71.1 (range 35-176) with a mean operative time of 111.9 (range 53-220) minutes, for an average of 0.64 (range 0.36-1.05) door openings/min. Nursing staff were responsible for 52.2% of total door openings, followed by anesthesia staff at 23.9% and orthopedic staff at 12.7%. In the preincision period, we observed an average of 0.84 door openings/min, with nursing and orthopedic personnel responsible for most of the door openings. The postincision period yielded an average of 0.54 door openings/min, with nursing and anesthesia personnel being responsible for most of the door openings.
Conclusion:There is a high incidence of door openings during TJA. Because we observed a range in the number of door openings per surgery, we believe it is possible to reduce this number during TJA.Contexte : Les ouvertures de porte perturbent le flux laminaire et accroissent la numération bactérienne au bloc opératoire. Nous avons voulu mesurer l'incidence des ouvertures de porte au bloc opératoire durant les chirurgies pour prothèse articulaire totale (PAT) et déterminer si des correctifs étaient requis ou s'il était possible de réduire la circulation du personnel au bloc opératoire.
Méthodes :Nous avons dénombré les ouvertures de porte durant 100 chirurgies électives primaires pour PAT; le personnel du bloc opératoire n'était pas au courant de l'intention de l'observateur. Le temps opératoire a été subdivisé en une période pré-incision, définie par l'intervalle entre l'ouverture des plateaux chirurgicaux et l'incision chirurgicale, et une période post-incision, définie par l'intervalle entre l'incision et l'application du pansement.
Background: Rupture of the proximal rectus femoris tendon has been well documented in the literature because of a bony avulsion of the anteroinferior iliac spine predominantly in the active adolescent population. Most of these ruptures are treated non-operatively with good functional outcomes. However, when conservative treatments fail, surgery is an option.Purpose: To describe a rare case of successful surgical management of a chronic ruptured proximal rectus femoris tendon.
Results:The patient progressively returned to competitive sports without any symptoms at four months post tendon repair. At final follow-up two years after surgical repair, the patient has a University of California, Los Angeles activity score of 10, and a Non-Arthritic Hip Score of 95/100.
Conclusion:Tendon avulsion of the rectus femoris muscle is a rare entity in the adult population. Surgical management of chronic tendon avulsion of the rectus femoris proved to be efficient and can be recommended when conservative treatment fails.
Adult periacetabular osteotomy (PAO) was originally performed through the classic Smith-Petersen approach for optimal operative visibility and acetabular fragment correction. Evolution towards an abductor-sparing technique significantly lowered the post-operative morbidity. The rectus-sparing approach represents a step further, but the innervation of the rectus femoris is theoretically more at risk. Although the topographic anatomy of the femoral nerve has been well described, it was never studied with specificity to surgical landmarks. The femoral nerve’s spatial relation with the anterior-inferior iliac spine (AIIS) and the amount of possible dissection in the rectus femoris and iliopsoas interval is uncertain. Seven formalin-preserved human cadaveric specimens without history of inguinal injury or surgery were dissected using the distal limb of an iliofemoral approach. The level of entry of motor innervation was measured and number of branches to the rectus femoris was noted. The average longitudinal distance from the AIIS to the first motor nerve to the rectus femoris was 8.6 ± 1.4 cm. The number of branches varied between 1 and 4 with the most common innervation pattern being composed of two segments. Dissection medial to the rectus femoris should not be carried out further than 7 cm distal to the AIIS and stretching of that interval during surgical exposure should be done cautiously. The clinical efficiency of the rectus-sparing approach should be studied further in order to confirm its advantage over the classic direct anterior approach. The study provides a better understanding of the localization and the anatomical variations of the structures encountered at the level of and below the AIIS. It also assesses the relative risk of denervation of the rectus femoris during PAO through the rectus-sparing approach. The authors recommend that the dissection medial to the rectus femoris should be carried out no further than 7 cm distal to the AIIS and stretching of that interval during surgical exposure should be done cautiously.
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.
