Surgical helmet systems in total joint arthroplasty: assessment of hood sterility and donning technique.

BACKGROUND: The incidence of prosthetic joint infection (PJI) is increasing, coincident with the rising volume of joint arthroplasty being performed. With recent controversy regarding the efficacy of surgical helmet systems (SHS) in preventing infection, the focus has turned to the correct donning techniques and usage of surgical hoods. The aim of this study was to compare the bacterial contamination of the operating surgeon's gloves after two common donning techniques of SHS hoods. We also evaluated the baseline sterility of the SHS hoods at the beginning of the procedure. METHODS: The bacterial contamination rate was quantified using colony-forming units (CFUs), with 50 trials performed per donning technique. Samples were cultured on 5% Columbia blood agar in ambient air at 37 °C for 48 h and all subsequent bacterial growth was identified using a MALDI-TOF mass spectrometer. In Group 1, the operating surgeon donned their colleague's hood. In Group 2, the operating surgeon had their hood applied by a non-scrubbed colleague. After each trial, the operating surgeon immediately inoculated their gloves onto an agar plate. The immediate sterility of 50 SHS hoods was assessed at two separate zones-the screen (Zone 1) and the neckline (Zone 2). RESULTS: There was no significant difference in contamination rates between the two techniques (3% vs. 2%, P = 0.99) or between right and left glove contamination rates. Immediately after donning, 6/50 (12%) of SHS hoods cultured an organism. Contamination rates at both the face shield and neckline zones were equivalent. The majority of bacteria cultured were Bacillus species. DISCUSSION: We found no significant difference in the operating surgeon's glove contamination using two common SHS hood-donning techniques when they were performed under laminar airflow with late fan activation. We suggest the SHS hood should not be assumed to be completely sterile and that gloves are changed if it is touched intraoperatively.

Return to Sport After Operative Fixation of Midshaft Clavicle Fractures in Professional Jockeys.

OBJECTIVE: Clavicle fractures are the most commonly observed fracture sustained in professional horse racing. This study is the first to report on time lost from injury and functional recovery after surgical fixation of midshaft clavicle fractures in professional jockeys. DESIGN: Retrospective cohort study. SETTING: Professional Horse Racing Ireland; Patients (or Participants): Professional Jockeys in Ireland with midshaft clavicular fractures managed with Open Reduction Internal Fixation. Interventions (or Assessment of Risk Factors or Independent Variables): Operative fixation with Open Reduction Internal Fixation. MAIN OUTCOME MEASURES: Assessment of postoperative Quick Disabilities of Arm Shoulder and Hand (QuickDASH) score and Patient Reported Outcome Measures assessing for associated complications and time to return to competition among professional athletes. RESULTS: Between 07/06/2013 and 29/09/2022, 22 patients met the predetermined inclusion criteria. Ninety-five percent of patients returned to competition at their preinjury level, one patient failed to return to competition for reasons unrelated to his injury. The mean time for return to competition was 68.14 days postinjury. Few complications were reported, whereas functional recovery was excellent across the cohort, with an average QuickDASH score of 0.85 (0.0-2.3). CONCLUSIONS: Plate fixation of midshaft clavicle fractures is effective and safe in the setting of professional horse racing. Ninety-five percent of patients can be expected to return within 14 weeks of injury. Patients returning at less than 7 weeks after injury had no adverse outcomes, suggesting a potential role for more aggressive rehabilitation postoperatively and ultimately, a quicker return to competition.

Readability of Patient Educational Materials in Sports Medicine.

Background: The internet has become an increasingly popular resource among sports medicine patients seeking injury-related information. Numerous organizations recommend that patient educational materials (PEMs) should not exceed sixth-grade reading level. Despite this, studies have consistently shown the reading grade level (RGL) of PEMs to be too demanding across a range of surgical specialties. Purpose: To determine the readability of online sports medicine PEMs. Study Design: Cross-sectional study. Methods: The readability of 363 articles pertaining to sports medicine from 5 leading North American websites was assessed using 8 readability formulas: Flesch-Kincaid Reading Grade Level, Flesch Reading Ease Score, Raygor Estimate, Fry Readability Formula, Simple Measure of Gobbledygook, Coleman-Liau Index, FORCAST Readability Formula, and Gunning Fog Index. The mean RGL of each article was compared with the sixth- and eighth-grade reading level in the United States. The cumulative mean website RGL was also compared among individual websites. Results: The overall cumulative mean RGL was 12.2 (range, 7.0-17.7). No article (0%) was written at a sixth-grade reading level, and only 3 articles (0.8%) were written at or below the eighth-grade reading level. The overall cumulative mean RGL was significantly higher than the sixth-grade [95% CI for the difference, 6.0-6.5; P < .001] and eighth-grade (95% CI, 4.0-4.5; P < .001) reading levels. There was a significant difference among the cumulative mean RGLs of the 5 websites assessed. Conclusion: Sports medicine PEMs produced by leading North American specialty websites have readability scores that are above the recommended levels. Given the increasing preference of patients for online health care materials, the imperative role of health literacy in patient outcomes, and the growing body of online resources, significant work needs to be undertaken to improve the readability of these materials.

Readability of Patient Educational Materials in Pediatric Orthopaedics.

BACKGROUND: Parents are increasingly turning to the internet to seek pediatric health information. Numerous organizations advise that patient educational materials (PEMs) should not surpass the sixth-grade reading level. We aimed to assess the readability of online pediatric orthopaedic PEMs. METHODS: The readability of 176 articles pertaining to pediatric orthopaedics from the American Academy of Orthopaedic Surgeons (AAOS), Pediatric Orthopaedic Society of North America (POSNA), and American Academy of Pediatrics (AAP) websites was assessed with the use of 8 readability formulae: the Flesch-Kincaid Reading Grade Level, the Flesch Reading Ease Score, the Raygor Estimate, the SMOG, the Coleman-Liau, the Fry, the FORCAST, and the Gunning Fog. The mean reading grade level (RGL) of each article was compared with the sixth and eighth-grade reading levels. The mean RGL of each website's articles also was compared. RESULTS: The cumulative mean RGL was 10.2 (range, 6.6 to 16.0). No articles (0%) were written at the sixth-grade reading level, and only 7 articles (4.0%) were written at or below the eighth-grade reading level. The mean RGL was significantly higher than the sixth-grade (95% confidence interval [CI] for the difference, 4.0 to 4.4; p < 0.001) and eighth-grade (95% CI, 2.0 to 2.4; p < 0.001) reading levels. The mean RGL of articles on the POSNA website was significantly lower than the mean RGL of the articles on the AAOS (95% CI, -1.8 to -1.0; p < 0.001) and AAP (95% CI, -2.9 to -1.1; p < 0.001) websites. CONCLUSIONS: Pediatric orthopaedic PEMs that are produced by the AAOS, the POSNA, and the AAP have readability scores that exceed recommendations. Given the increasing preference of parents and adolescents for online health information, the growing body of online PEMs, and the critical role that health literacy plays in patient outcomes, substantial work is required to address the readability of these materials.

Reliability of a Smartphone Goniometric Application in the Measurement of Hip Range of Motion Among Experienced and Novice Clinicians.

CONTEXT: Deficits in the hip range of motion are associated with hip and groin injuries. Accurate and reliable goniometric measurements are important in identifying those at risk of injury and determining the efficacy of treatment interventions. Smartphone goniometric applications are regularly used to assess joint ranges of motion; however, there is limited knowledge on the reliability of this method in relation to the hip, particularly between clinicians with different levels of experience. OBJECTIVE: To determine the intratester and intertester reliability of a smartphone clinometer application for the assessment of hip goniometric measurements in healthy volunteers by an experienced and novice clinician. DESIGN: Reliability study. SETTING: University Athletic Therapy facility. PARTICIPANTS: Physically active, university students. MAIN OUTCOME MEASURES: The study determined the intra- and intertester (experienced vs novice clinician) reliability of goniometric measurements of the hip joint (modified Thomas test and seated hip internal and external rotation) using a smartphone goniometric application. Intraclass correlation coefficients (ICCs), standard error of measurement, and minimal detectable change at a 95% confidence interval were used to assess reliability. RESULTS: Goniometric measurements demonstrated good to excellent relative intratester reliability for the modified Thomas test (ICC = .94), external rotation (ICC = .93-.95), and internal rotation (ICC = .80-.81). Intertester reliability for expert and novice clinicians was also excellent for the modified Thomas test (ICC = .98), external rotation (ICC = .95), and internal rotation (ICC = .92). Intratester and intertester standard error of measurement and minimal detectable change at 95% confidence interval values were similar for both testers and ranged from 1.9° to 3.6° and 5° to 10.1° and from 1.1° to 2.3° and 2.9° to 6.5°, respectively. CONCLUSION: Smartphone-based goniometric measurements of hip range of motion have high intratester and intertester reliability for novice and expert clinicians. It may be a useful, simple, and inexpensive resource for clinicians.

Surgeon proficiency in robot-assisted spine surgery.

Continuous technical improvement in spinal surgical procedures, with the aim of enhancing patient outcomes, can be assisted by the deployment of advanced technologies including navigation, intraoperative CT imaging, and surgical robots. The latest generation of robotic surgical systems allows the simultaneous application of a range of digital features that provide the surgeon with an improved view of the surgical field, often through a narrow portal. There is emerging evidence that procedure-related complications and intraoperative blood loss can be reduced if the new technologies are used by appropriately trained surgeons. Acceptance of the role of surgical robots has increased in recent years among a number of surgical specialities including general surgery, neurosurgery, and orthopaedic surgeons performing major joint arthroplasty. However, ethical challenges have emerged with the rollout of these innovations, such as ensuring surgeon competence in the use of surgical robotics and avoiding financial conflicts of interest. Therefore, it is essential that trainees aspiring to become spinal surgeons as well as established spinal specialists should develop the necessary skills to use robotic technology safely and effectively and understand the ethical framework within which the technology is introduced. Traditional and more recently developed platforms exist to aid skill acquisition and surgical training which are described. The aim of this narrative review is to describe the role of surgical robotics in spinal surgery, describe measures of proficiency, and present the range of training platforms that institutions can use to ensure they employ confident spine surgeons adequately prepared for the era of robotic spinal surgery.

Timing of surgical fixation in traumatic spinal fractures: A systematic review.

BACKGROUND: The optimal timing of fracture fixation following spinal injury is controversial. Many spinal fractures occur as part of polytrauma requiring a complex management strategy. Whilst the decision to stabilize unstable spinal column injuries is without debate, the duration between injury and definitive fixation can impact on the incidence of post-operative complications. This study was designed to systemically summarize and compare the complication profile of early vs late stabilization of spinal injuries, in an attempt to unveil an appropriate treatment protocol for traumatic spinal fractures. METHODS: A comprehensive search strategy was performed on the PubMed, Cochrane, and Google Scholar databases using key words. The search strategy provided 1120 results. Forty-six articles were reviewed for full-text. Reference lists were analysed for potential additional texts. RESULTS: Sixteen articles met the inclusion criteria and were included for systematic review. Studies were controversial and the overall result was inconclusive. Several studies favour early stabilisation to reduce post-surgical complication rates, especially in cases of patients with high Injury Severity Scale (ISS) scores. However, this is challenged by a small number of studies reporting a higher mortality rate in the early-stabilisation cohort. CONCLUSION: Due to limited studies and a small overall cohort, the authors would cautiously recommend the early surgical fixation of unstable spine fractures in the stable trauma patient. For severely injured patients, the discordance among literature warrants the need for further investigation.
