    Distal oblique metatarsal osteotomy for hallux valgus deformity: A clinical analysis
    (Elsevier Science Inc, 2017) Güler, Olcay; Yılmaz, Barış; Mutlu, Serhat; Çerçi, Mehmet Halis; Heybeli, Nurettin
    We compared the outcomes of the distal oblique metatarsal (DOM) osteotomy, which is parallel to the articulation surface of the proximal phalanx, with those of the chevron osteotomy and evaluated whether displacement and shortening of the first metatarsal have any effect on the incidence of metatarsalgia and patient satisfaction. Patients treated with the DOM osteotomy (n = 30) or distal chevron osteotomy (n = 31) were evaluated retrospectively. The chevron and DOM osteotomies both provided significant improvement in the first intermetatarsal angle (p <.001), hallux valgus angle (p <.001), distal metatarsal articular angle (p <.001), range of first metatarsophalangeal joint motion (p <.001), American Orthopaedic Foot and Ankle Society score (p <.001), and sesamoid position (p <.001), without any significant differences between the 2 groups. Patient satisfaction and metatarsalgia also were not different between the study groups. The DOM osteotomy group had higher plantar displacement (0.1 +/- 0.1 mm versus 1.0 +/- 0.1 mm; p <.001) and absolute shortening of the first metatarsal (1.0 +/- 0.4 mm versus 6.8 +/- 1.0 mm; p <.001). In conclusion, the DOM osteotomy is an alternative treatment method for mild and moderate hallux valgus.

    Tendons and ligaments
    (Springer International Publishing, 2015) Heybeli, Nurettin; Baran Kömür, Heval; Yılmaz, Barış; Güler, Olcay
    Tendons and ligaments are complex structures and have different anatomical and dynamic properties. Injury of tendons and ligaments remodel with scar formation with differences in themselves. Although scarring depends on the quality and quantity of the injured tissues, it can be qualified with appropriate rehabilitation. In normal conditions, scar formation prevents returning of normal tendon function because of its structural and biological limitations. It has been shown that reconstruction of injured tendons and ligaments with allografts and autografts in different clinical and experimental studies. Despite of these developments, healing process of both biological and biomechanics of the tendons and ligaments is still have to be investigated.
