Idiopathic Bilateral Brachymetacarpia–Brachymetatarsia with Third Metacarpal and Fourth Metatarsal Involvement- Case Report

Background: Brachymetacarpia and brachymetatarsia are rare congenital deformities that develop as a result of premature closure of the epiphyseal plates of the metacarpal and metatarsal bones. The deformity is most often noticed during childhood or adolescence and may be associated with certain syndromic or endocrinological conditions. In cases of brachymetacarpia, in addition to functional problems, cosmetic reasons such as disruption of the joint contour during fist formation or asymmetry of finger lengths constitute indications for surgical intervention. In brachymetatarsia, in addition to cosmetic concerns, transfer metatarsalgia, pain, callus formation, and difficulty in wearing shoes are the main reasons requiring surgical intervention. It most frequently involves a single bone, and multiple and bilateral forms have been reported only rarely in the literature. Materials and Methods: In this case report, a 22-year-old female patient is described who is characterized by bilateral shortening of the third metacarpal and fourth metatarsal bones, without any accompanying syndromic features or endocrinopathy. Results: Radiological examinations revealed marked symmetry, and no pathological findings were detected in laboratory tests. Surgical and conservative treatment options were evaluated; according to the patient’s preference, surgical intervention was planned for the hand deformity, while the foot deformity was managed conservatively. Conclusions: This case contributes to the literature not only because of its rare multiple and bilateral bone involvement but also by the presence of a family history.
