“…We found high intraobserver agreement for digit measurements and ratios obtained from 3D hand images, indicating that manually placed landmarks could be localized reliably on the 3D surface of the digits. These results are in agreement with recent work on 3D hand images by Hoevenaren et al (a, b) and indicate that 3D photogrammetry is a viable method for capturing digit measurements and deriving ratios. Intraobserver agreement results were similarly high for 2D scanning and, although slightly worse, were still within an acceptable error range for direct anthropometry.…”

“…The use of this type of technology for hand imaging and measurement is limited. In two recent reports, Hoevenaren et al (a, b) showed that 3D photogrammetry is capable of high image reproducibility and landmark reliability for hand morphology. In this brief report, we investigated the suitability of digital 3D stereophotogrammetry to scan the human hand and the reliability of 3D surface image analysis software to obtain second digit and fourth digit measurements from these scans.…”

Digit measurements and derived ratios from 3D stereophotogrammetry showed high intraobserver agreement (similar to more traditional methods) suggesting that landmarks could be placed reliably on 3D hand surface images. While digit length measurements were found to be comparable across all three methods, ratios derived from direct anthropometry tended to be higher than those calculated indirectly from 2D or 3D images.

“…The photographs were taken by a trained technician following the principles described in the study by Hoevenaren et al Using these principles, data from the 3D stereophotogrammetry were transferred to a 3D virtual model using Maxilim® software (Medicim NV, Mechelen, Belgium). A reference frame was set up according to a reproducible method, in order to align all hand models in the same orientation [14]. Thirty soft tissue landmarks were identified on each image (Table 1).…”

BackgroundAcral overgrowth is a highly common clinical sign in patients with active acromegaly. To what extent this overgrowth persists after long-term remission of acromegaly is largely unknown. Using the new imaging technique of three-dimensional (3D) stereophotogrammetry, it is possible to accurately investigate soft tissue changes of the hand. The aim of the recent study was to compare the 3D soft tissue characteristics of the hands of patients in long-term remission of acromegaly to those of a healthy pair matched control group.MethodsA case-control study was performed at a tertiary referral center. Twelve patients in remission of acromegaly (58 % male, mean age 58.3 years, mean BMI 29.6 kg/m2) were compared to twelve age-, gender-, ethnicity-, and BMI-matched control subjects. Of each individual, 3D photographs of both hands were acquired and analyzed using a 3D computer software program.ResultsThe patients in long-term remission of acromegaly have overgrowth of soft tissue of the hand compared to matched control subjects, with a larger length and width of the hand (p = 0.0025, p = 0.0017, respectively). Furthermore, the diameters measured at the proximal interphalangeal (PIP) joints of the individual fingers are larger in the acromegaly patients.ConclusionsSignificant soft tissue overgrowth of the hand persists in former acromegaly patients, even after long-term remission. Analysis of 3D hand photographs is an accurate and easy tool to evaluate the acral soft tissue patterns in acromegaly.Level of Evidence: Level III, diagnostic study.

“…After investigating the reproducibility of the image acquisition method, anatomical landmarks were placed on each of the 34 photographs according to the method developed by Hoevenaren et al [ 15 ]. These landmarks could then be used for comparing different hands and to compute an average hand model.…”

PurposeUsing three-dimensional (3D) stereophotogrammetry precise images and reconstructions of the human body can be produced. Over the last few years, this technique is mainly being developed in the field of maxillofacial reconstructive surgery, creating fusion images with computed tomography (CT) data for precise planning and prediction of treatment outcome. Though, in hand surgery 3D stereophotogrammetry is not yet being used in clinical settings.MethodsA total of 34 three-dimensional hand photographs were analyzed to investigate the reproducibility. For every individual, 3D photographs were captured at two different time points (baseline T0 and one week later T1). Using two different registration methods, the reproducibility of the methods was analyzed. Furthermore, the differences between 3D photos of men and women were compared in a distance map as a first clinical pilot testing our registration method.ResultsThe absolute mean registration error for the complete hand was 1.46 mm. This reduced to an error of 0.56 mm isolating the region to the palm of the hand. When comparing hands of both sexes, it was seen that the male hand was larger (broader base and longer fingers) than the female hand.ConclusionsThis study shows that 3D stereophotogrammetry can produce reproducible images of the hand without harmful side effects for the patient, so proving to be a reliable method for soft tissue analysis. Its potential use in everyday practice of hand surgery needs to be further explored.
