Brachymetatarsia: Surgical Management, Case Report, and Literature Review
Case Reports in Orthopedics, 2022 Background. Brachymetatarsia is defined by an abnormal shortening of the metatarsal bone. This rare condition is mostly primary and congenital. Consequences of this malformation are both esthetic and functional, due to pain and mechanical problems in the

BONE LENGTHENING BY PHYSIAL DISTRACTION. AN EXPERIMENTAL STUDY [PDF]
Journal of Pediatric Orthopaedics, 1986 Experimental physial distraction was carried out in the distal part of the femur in 45 two-month old lambs in order to study the basic mechanisms of lengthening as well as the viability of the growth cartilage after using this method. The animals were divided into three groups (A, B and C), and each group into three subgroups (1, 2 and 3) according to ...

Delayed distraction in bone lengthening [PDF]
Acta Orthopaedica Scandinavica, 1992 We compared delayed distraction (DD) with immediate distraction (ID) in bone-lengthening. Open femoral diaphyseal osteotomy was performed on 24 three-month-old lambs, and external distractor fixators were applied. In the ID group (n 12), distraction commenced on the first postoperative day; in the DD group (n 12), distraction was delayed until the ...

Analysis of strut-to-bone lengthening ratio for hexapod frames using mathematical modeling
Journal of Limb Lengthening & Reconstruction, 2017 Background: Hexapod external fixators often incorporate bone lengthening as part of a multi-planar deformity correction plan. The hexapod struts, however, do not distract in the direction of bone lengthening. Their oblique orientation to the ring creates

Limb lengthening in pediatric patients with ollier's disease
Journal of Limb Lengthening & Reconstruction, 2017 Background: Ollier's disease is a non-hereditary skeletal disorder. Orthopedic management of limb length discrepancy could be complex given the nature of bone pathology, the significant amount of length discrepancy and the difficulty to predict it.

Travmatologiâ i Ortopediâ Rossii, 2021 Background. The methods of “lengthening over the nail” (LON) and the sequential use of the external fixation and nailing in the option “lengthening and then the nail” (LATN) are characterized by ignoring non-observance of the formulated by G.A.
