“…They revealed that combining scores from several different bones enable a reasonable estimate of potential age in a test application of the model. Aydinlioglu et al (1998) conducted radiographic measurements for metacarpals and phalanges lengths of the hand, and they pointed out that the morphometric relations between the lengths of metacarpals and phalanges may be useful for surgical interventions, such as lengthening and shortening procedures of metacarpals and phalangeas. As a result of our measurements, we found consistent proportions between the metatarsals and phalanges, similar to their studies.…”

Mathematical relation between metatarsals and between phalanges in terms of their lengths and widths in themselves is considered to be significant with respect to its functional and aesthetic roles. The objective of this study is to conduct measurements for determining lengths and widths of metatarsals and phalanges on the foot radiographs and to determine possible mathematical correlations between metatarsals themselves and between phalanges themselves in terms of their lengths and widths. Anteroposterior right and left foot radiographs were taken from 100 volunteers (50 men and 50 women). Lengths and widths of the metatarsals and phalanges were measured in millimeter on radiographs. The mean, minimum and maximum values, and standard deviations of each bone's length and width were studied and data were put into formulation. The results were evaluated by Regression statistical test, and the relation between metatarsals and between phalanges in terms of their lengths and widths was studied. As a result of the measurements, we found fixed proportions between metatarsals in themselves and between phalanges in themselves in terms of their lengths and widths. Knowing these morphometric relations may be useful for performing any surgical procedures designed to manage any defects or imperfections of the foot, chief among them is shortness.

“…In unilateral cases, distraction lengthening continued until the metacarpal was equal in length to the contralateral normal metacarpal. In bilateral cases, the estimated length of metacarpal was calculated using the method of Aydinlioglu et al 12 (First metacarpal=0.67x second metacarpal=0.71x third metacarpal=0.78x fourth metacarpal=0.84x fifth metacarpal). When the proposed length was reached, adequate bony union was confirmed if cortical continuity was present in a total of 3 anteroposterior and lateral radiographs.…”

distraction rate, the less the healing index and consolidation time. Conclusion. Age has the most effect on healing index and consolidation time. Metacarpal lengthening using callus distraction is recommended. Adolescence is the most appropriate time to perform distraction lengthening of a congenitally short metacarpal. This will avoid additional lengthening of normal metacarpals prior to epiphyseal closure.

“…Determining the appropriate amount of lengthening of a short bone is challenging in a bilateral involvement. We used a formula presented by Aydinlioglu et al [1] to determine the amount of metacarpal lengthening. This formula indicates the mathematical relations between the lengths of metacarpal bones and phalanges as follows:…”

We performed bone lengthening surgery on 12 metacarpals and 14 metatarsals of 15 patients. The mean age for metacarpal and metatarsal lengthening was 14.5 (10-21) and 17.5 (10-25) years, respectively. We used a unilateral or a circular external fixator. The mean healing index of the metacarpals and metatarsals was 1.6 (1.1-2.3) and 1.6 (1.0-2.0) months/cm, respectively. The mean increase in metacarpal and metatarsal length was 17.6 (13-26) and 24.3 (20-30) mm, respectively. The functional scores of the metatarso-phalangial (MTP) joint of lengthened metatarsals for the lesser toe were excellent in 12 and good in two cases based on the American Orthopaedic Foot and Ankle Society (AOFAS) scoring system. Complications were seen in six of the metatarsal lengthening cases including four angulations, one subluxation and one non-union. We conclude that the periosteum must be protected with percutaneous osteotomy and lengthening should be performed at a rate of 0.25 mm twice a day and should not exceed 40% of the original bone length (or >20 mm).Résumé Nous avons réalisé une chirurgie d'allongement sur 12 métacarpiens et 14 métatarsiens chez 15 patients.
