The Effect of Radial Inclination on the Stage of Kienbock Disease at the Time of Initial Diagnosis.

BACKGROUND: Negative ulnar variance is a widely accepted risk factor for the development of Kienbock disease (KD). Variation in radial inclination has been proposed as a risk factor, but evidence thus far has been inconclusive. We aim to clarify the relationship between radial inclination and KD. METHODS: A retrospective analysis of all KD patients from a single institution from 2007 to 2021 was conducted. Radiographs were reviewed to measure anatomic parameters and stage of disease. An exploratory multinomial regression model was created to examine the association of patient age, radial height, ulnar variance, radial inclination, volar tilt, scapholunate angle, duration of symptoms prior to evaluation, history of wrist trauma, and diagnosis of diabetes with stage of disease. RESULTS: Fifty-seven cases of KD were identified, with a mean duration of disease of 33.3 months. A history of trauma to the wrist was common (53%) and significantly associated with stage of disease at initial presentation. Twenty-seven cases (47%) were stage IIIB or greater. The average initial radial inclination, radial height, and ulnar variance was 21.9°, 10.7 mm, and -1.23 mm, respectively. A multinominal logistic regression model revealed decreased initial radial inclination is associated with Lichtman stage IIIB or greater at the time of initial patient presentation. CONCLUSIONS: A correlation exists between decreased radial inclination and more advanced KD at presentation, suggesting this may be a risk factor for disease progression. This correlation is strengthened by our finding of decreased ulnar variance being associated with later stage at presentation, which is one of the most widely accepted proposed risk factors for development and progression of disease. LEVEL OF EVIDENCE: IV.

Editorial Commentary: Gracilis-Sparing Anterior Cruciate Ligament Hamstring Graft Reconstruction Is Less Invasive Than Semitendinosus-Gracilis Graft Harvest, and Shows No Clinical Difference in Outcomes With Grafts Greater Than 8 mm in Diameter.

Although patellar tendon grafts are most commonly used for anterior cruciate ligament reconstruction in the United States, hamstring autograft is most commonly used worldwide. Hamstring advantages include easy, quick harvest; low morbidity; ease of rehabilitation (compared with patellar tendon grafts); and relatively less pain. Historically, both the semitendinosus (ST) and gracilis are harvested, but by doubling, tripling, or quadrupling the ST to achieve an 8-mm graft, the gracilis can be spared, resulting in less knee flexion weakness. However, recent research has shown no clinically important difference between ST and ST-gracilis patient outcomes.

Implementation of a Preoperative Huddle at a Level 1 Trauma Center.

OBJECTIVE: Medical errors resulting in patient harm still occur at an alarmingly high rate. Surgery is a high-risk area that can frequently result in patient harm if errors occur. There is a need for standardization of communication and processes to decrease errors. We sought to determine whether the implementation of a preoperative huddle at our hospital could standardize communication and decrease medical errors. METHODS: A unique preoperative huddle was developed and implemented at a level 1 trauma center. We reviewed data before and after the implementation of the preoperative huddle including patient surveys and comments, the percentage of on-time operating room (OR) starts, OR turnover times, and the number of sentinel events. RESULTS: After huddle implementation, we observed a trend of improvement in our patient survey results on patient's perception that the doctors/nurses explained the procedure understandably after huddle implementation. There was a statistically yet limited clinically significant increase in OR turnover time from 37 to 40 minutes (P < 0.001). There was also an increase in on-time OR starts from 37% to 45% (P < 0.001). We observed a decrease in the number of sentinel events, with only 1 occurring each year since implementation. CONCLUSIONS: A preoperative huddle was successfully implemented at a level 1 trauma hospital and helped standardize communication without significantly disrupting workflow. To our knowledge, this method of preoperative huddling has not been previously described in the literature.
