The Intrarater and Interrater Reliability of the OMT Classification Among Physicians With a Different Background.

BACKGROUND: The Oberg-Manske-Tonkin (OMT) classification established excellent reliability scores in several validation studies. However, one study published in 2022 found much lower scores in a subanalysis of their sample when very simple anomalies were excluded. Our study assessed the reliability of the OMT among physicians with a different background, all involved in congenital hand anomaly care, and analyzed codes with less agreement. Time required for classification was recorded to give an indication on its usability. METHODS: One hundred digital cases were classified twice with a minimal 1-month time interval, with the use of the 2020 version of the OMT. Two pediatric hand surgeons, 2 rehabilitation specialists, and 2 plastic surgery residents participated in this reliability analysis. The use of multiple codes was allowed. The intra- and interrater reliability was assessed for all 15 possible rater couples by calculating percentage of agreement. Cohen's kappa was calculated along with a 95% confidence interval. For the analysis of individual codes with less agreement, we calculated positive agreement with the use of a summed agreement table. Time necessary for classification was documented in seconds. RESULTS: The inter- and intrarater agreement was moderate with a mean Cohen's kappa of 0.45 and 0.60 retrospectively. On average, 39 seconds per case were necessary for the first and 24 seconds for the second rating. Background did not influence the level of agreement. Lowest agreement levels (ie, lowest positive agreement) were observed with all the arthrogryposis multiplex congenita subgroups, the "other" subgroups of isolated congenital contractures, syndromic syndactyly, and synpolydactyly. Codes commonly used interchangeably were symbrachydactyly and transverse deficiency and the distinction between these anomalies of only the hand or the entire upper limb; symbrachydactyly and brachydactyly; and camptodactyly and distal arthrogryposis. CONCLUSIONS: Our study showed a moderate reliability, emphasizing the complexity of this heterogeneous patient population. Despite its imperfections, the OMT remains the best and most versatile classification tool at hand. Its main purpose may lie in contributing to a universal language for research. LEVEL OF EVIDENCE: I.

Trocar port scar quality in morbidly obese patients after bariatric surgery.

BACKGROUND: Patient satisfaction of scar quality and their influence on health-related quality of life (HRQoL) have never been investigated in morbidly obese patients. OBJECTIVES: Our objectives were (1) to assess scar quality 1 year post laparoscopic bariatric surgery by means of the Patient and Observer Scar Assessment Scale (POSAS), and (2) to examine the influence of patients' perception of scar quality on patients' HRQoL. SETTING: A large Bariatric Center of Excellence in the Netherlands. METHODS: This was a descriptive pilot study of patients who underwent primary laparoscopic bariatric surgery. One year after surgery, patients and 2 observers completed the POSAS. HRQoL was assessed by using the RAND-36. Agreement of POSAS scores between patients and observers was calculated with intraclass correlation coefficient. Correlations between POSAS scores and HRQoL scores were calculated with Spearman's rho. RESULTS: A total of 50 patients were included. Patients scored their scar quality worse than observers (21 versus 15-16), particularly on visual parameters (4-5 versus 2-3). Patients and observers showed poor agreement on all POSAS items (intraclass correlation coefficient = .16-.32). No significant correlations were detected between POSAS and HRQoL scores. CONCLUSION: While patient scar quality satisfaction was relatively low after bariatric surgery, these outcomes were not correlated with HRQoL. Bariatric surgeons should be aware that patients could have a different view on scar quality compared with them. This realization is important to manage patient expectations regarding scar quality after bariatric surgery. Effective communication may improve patient satisfaction as an outcome.

Simultaneous bilateral hip fractures following a simple fall in an elderly patient without predilecting comorbidities.

Simultaneous bilateral hip fractures are rare, mostly being caused by violent forces or in patients with bone metabolism disorders. We present the case of an elderly patient who sustained simultaneous bilateral hip fractures following a simple fall without having any known predilecting comorbidities other than advanced age. Only four cases have been described of elderly patients without comorbidity with simultaneous bilateral hip fractures following low-energy traumas. This rareness potentially leads to misses of this diagnosis.

A Reliable Method to Measure Lip Height Using Photogrammetry in Unilateral Cleft Lip Patients.

There is still no reliable tool to determine the outcome of the repaired unilateral cleft lip (UCL). The aim of this study was therefore to develop an accurate, reliable tool to measure vertical lip height from photographs. The authors measured the vertical height of the cutaneous and vermilion parts of the lip in 72 anterior-posterior view photographs of 17 patients with repairs to a UCL. Points on the lip's white roll and vermillion were marked on both the cleft and the noncleft sides on each image. Two new concepts were tested. First, photographs were standardized using the horizontal (medial to lateral) eye fissure width (EFW) for calibration. Second, the authors tested the interpupillary line (IPL) and the alar base line (ABL) for their reliability as horizontal lines of reference. Measurements were taken by 2 independent researchers, at 2 different time points each. Overall 2304 data points were obtained and analyzed. Results showed that the method was very effective in measuring the height of the lip on the cleft side with the noncleft side. When using the IPL, inter- and intra-rater reliability was 0.99 to 1.0, with the ABL it varied from 0.91 to 0.99 with one exception at 0.84. The IPL was easier to define because in some subjects the overhanging nasal tip obscured the alar base and gave more consistent measurements possibly because the reconstructed alar base was sometimes indistinct. However, measurements from the IPL can only give the percentage difference between the left and right sides of the lip, whereas those from the ABL can also give exact measurements. Patient examples were given that show how the measurements correlate with clinical assessment. The authors propose this method of photogrammetry with the innovative use of the IPL as a reliable horizontal plane and use of the EFW for calibration as a useful and reliable tool to assess the outcome of UCL repair.
