“…Several scoliosis screening methods, such as the forward bending test, scoliometer, Moiré topography, and 3D scanner, have been shown to possess sufficient sensitivity and specificity to detect scoliosis. 5,12,19 These conventional methods need trained examiners to perform the screening tests and evaluate the results. 5,7,13,14 In this regard, our newly developed screening method has the advantage that it may lead to the development of future screening tools that enable subjects to conduct self-screening repeatedly, noninvasively, and conveniently at home.…”

Study Design. A single-center prospective observational study. Objective. To clarify the usefulness of a novel scoliosis screening method using a 3-dimensional (3D) human fitting application and a specific bodysuit. Summary of Background Data. Several scoliosis screening methods, such as scoliometer and Moiré topography, are available for detecting scoliosis. In the present study, a novel screening method for scoliosis using a 3D human fitting application and a specific bodysuit was developed. Methods. Patients with scoliosis or suspected scoliosis, non-scoliosis patients, and healthy volunteers were enrolled. They were divided into Non-Scoliosis and Scoliosis groups. The Scoliosis group was further subdivided into Mild-, Moderate-, and Severe-Scoliosis. Patients’ characteristics and Z values, which were calculated by a 3D virtual human body model created by a 3D human fitting application and a specific bodysuit to evaluate trunk asymmetry caused by scoliosis, were compared between the Non-Scoliosis and Scoliosis groups or among the Non-, Mild-, Moderate- and Severe-Scoliosis groups. Finally, the optimal cutoff of the Z value was determined to detect moderate to severe scoliosis using receiver operating characteristics (ROC) curve analysis. Results. A total of 101 patients were included. The Non-Scoliosis group consisted of 47 patients, and the Scoliosis group included 54 patients, with 11, 31, and 12 patients in the Mild-, Moderate-, and Severe-Scoliosis groups, respectively. The Scoliosis group showed a significantly higher Z value than the Non-Scoliosis group. The Moderate- or Severe-Scoliosis group had a significantly higher Z value than the Non- or Mild-Scoliosis group. The ROC curve analysis revealed that the optimal cutoff of the Z value was 19.9 mm (sensitivity, 95.3%; specificity, 58.6%). Conclusion. A novel scoliosis screening method consisting of a 3D human fitting application and a specific bodysuit may be useful for detecting moderate to severe scoliosis.

“…The quantification of surface topography (ST) in AIS has evolved from the subjective scoring of diagrams and photographs 15 – 22 to objective methods like the Moiré technique 23 , 24 , rasterstereography 25 – 31 , photogrammetry 32 – 34 , depth sensors 35 , 36 and infrared thermography 37 that generate cosmesis metrics and indices. Limitations of current methods include complicated patient positioning and the use of ambiguous anatomical landmarks which are the major sources of measurement errors 38 .…”

“…Cosmetic improvement has been shown to directly influence patient quality of life 1213 , and correcting the aesthetics of the torso is therefore a prime consideration when treating AIS 14 . Consequently, significant effort has been invested into developing metrics that characterise the posterior surface of the torso.The quantification of surface topography (ST) in AIS has evolved from the subjective scoring of diagrams and photographs [15][16][17][18][19][20][21][22] to objective methods like the Moiré technique 23,24 , rasterstereography [25][26][27][28][29][30][31] , photogrammetry 32-34 ,…”

Adolescent Idiopathic Scoliosis (AIS) is a 3D spine deformity that also causes ribcage and torso distortion. While clinical metrics are important for monitoring disorder progression, patients are often most concerned about their cosmesis. The aim of this study was to automate the quantification of AIS cosmesis metrics, which can be measured reliably from patient-specific 3D surface scans (3DSS). An existing database of 3DSS for pre-operative AIS patients treated at the Queensland Children’s Hospital was used to create 30 calibrated 3D virtual models. A modular generative design algorithm was developed on the Rhino-Grasshopper software to measure five key AIS cosmesis metrics from these models—shoulder, scapula and hip asymmetry, torso rotation and head-pelvis shift. Repeat cosmetic measurements were calculated from user-selected input on the Grasshopper graphical interface. InterClass-correlation (ICC) was used to determine intra- and inter-user reliability. Torso rotation and head-pelvis shift measurements showed excellent reliability (> 0.9), shoulder asymmetry measurements showed good to excellent reliability (> 0.7) and scapula and hip asymmetry measurements showed good to moderate reliability (> 0.5). The ICC results indicated that experience with AIS was not required to reliably measure shoulder asymmetry, torso rotation and head-pelvis shift, but was necessary for the other metrics. This new semi-automated workflow reliably characterises external torso deformity, reduces the dependence on manual anatomical landmarking, and does not require bulky/expensive equipment.

Background Ultrasound-guided percutaneous cryoablation (PCA) for early-stage breast cancer (ESBC) can be performed under local anesthesia in an outpatient clinic. This study continues a pilot stage to examine local control, safety, patient quality of life (QoL), satisfaction and cosmetic outcomes of cryoablation for ESBC. Methods PCA was performed under local anesthesia for patients with primary ESBC, followed by radiation and endocrine therapies. Oncologic outcomes were examined by imaging (mammography, ultrasound, MRI) at baseline and 1, 6, 12, 24, 36, and 60 months post-cryoablation. EQ-VAS, EQ-5D-5L, subjective satisfaction and Moiré topography were used to measure health-related QoL outcomes. Results Eighteen patients, mean aged 59.0 ± 9.0 years, mean tumor size 9.8 ± 2.3 mm, ER + , PR + (17/18), HER2-, Ki67 < 20% (15/18), underwent PCA and were followed for a mean of 44.3 months. No serious adverse events were reported, and no patients had local recurrence or distant metastasis in the 5-year follow-up. Cosmetic outcomes, satisfaction level, and QoL all improved post-cryoablation. Five-year average reduction rates of the cryolesion long, short, and depth diameters, on US, were 61.3%, 42.3%, and 22.8%, respectively, compared to the 86.2% volume reduction rate on MRI. The correlation coefficient between MRI and US measurement criteria was highest for the long diameter. During follow-up, calcification of the treated area was observed in 13/18 cases. Conclusion Cryoablation for ESBC is an effective and safe procedure with excellent cosmetic outcomes and improved QoL. This study contributes to the growing evidence supporting cryoablation as a potential standard treatment for ESBC, given compliance to pre-defined patient selection criteria.
