Establishing a common instantaneous center of rotation for the metatarso-phalangeal and metatarso-sesamoid joints: a theoretical geometric model based on specific morphometrics.

J Orthop Surg Res 2019 Apr 16;14(1):107. Epub 2019 Apr 16.

Center for Statistical Research and Methodology, U.S. Census Bureau, Washington, D.C., USA.

Background: Previous research has identified separate sagittal plane instantaneous centers of rotation for the metatarso-phalangeal and metatarso-sesamoid joints, but surprisingly, it does not appear that any have integrated the distinctive morphological characteristics of all three joints and their respective axes into a model that collectively unifies their functional motions. Since all joint motion is defined by its centers of rotation, establishing this in a complicated multi-dimensional structure such as the metatarso-phalangeal-sesamoid joint complex is fundamental to understanding its functionality and subsequent structural failures such as hallux abducto valgus and hallux rigidus.

Methods: Based on a hypothesis that it is possible to develop an instantaneous center of rotation common to all four osseous structures, specific morphometrics were selected from a sequential series of 0. Read More

Range of motion in the cervical spine after odontoid fracture treated with anterior screw fixation.

J Orthop Surg Res 2019 Apr 15;14(1):104. Epub 2019 Apr 15.

Medical Faculty, University of Rzeszów, Kopisto 2A Avenue, 35-959, Rzeszow, Poland.

Background: It is believed that direct odontoid screw fixation preserves the physiological cervical range of motion following surgery. However, there are no clinical studies confirming the motion sparing value of this technique. This study aims to (1) to assess active cervical range of motion following types II and III odontoid fracture, successfully treated with anterior odontoid screw fixation, and (2) to examine the relationship between the range of motion of the head and duration of collar usage, neck pain, quality of life, and patients' age.

Progression of local kyphosis after conservative treatment for compressive cervical spine fracture with spinal cord injury.

J Orthop Surg Res 2019 Apr 11;14(1):98. Epub 2019 Apr 11.

Departments of Orthopaedic Surgery, Graduate School of Medical Sciences, Kyushu University, 3-1-1 Maidashi, Higashiku, Fukuoka, 812-8582, Japan.

Introduction: Compressive-flexion type cervical spine fracture is typically accompanied by apparent dislocation of the facet joints, undesirable cervical alignment, and devastating neurological dysfunction, which provides strong rationale for rendering prompt operative treatment. However, the validity of conservative treatment for compressive-flexion cervical spine injury in cases with preserved congruity of the facet joints has yet to be elucidated. The purpose of this study is to evaluate the long-term outcome of cervical alignment following conservative treatment for compressive-flexion cervical spine injury with preserved congruity of the facet joints.

Microcirculatory consequences of limb ischemia/reperfusion in ovariectomized rats treated with zoledronic acid.

J Orthop Surg Res 2019 Apr 4;14(1):95. Epub 2019 Apr 4.

Institute of Surgical Research, University of Szeged, Pulz u. 1, Szeged, H-6724, Hungary.

Background: Nitrogen-containing bisphosphonates (BIS) are potent therapeutics in osteoporosis, but their use may result in osteonecrotic side-effects in the maxillofacial region. Periosteal microcirculatory reactions may contribute to the development of bone-healing complications, particularly in osteoporotic bones, where ischemia-reperfusion (IR) events often develop during orthopaedic/trauma interventions. The effect of BIS on the inflammatory reactions of appendicular long bones has not yet been evaluated; thus, we aimed to examine the influence of chronic zoledronate (ZOL) administration on the periosteal microcirculatory consequences of hindlimb IR in osteopenic rats.

How coronal alignment affects distal femoral anatomy: an MRI-based comparison of varus and valgus knees.

J Orthop Surg Res 2019 Apr 2;14(1):92. Epub 2019 Apr 2.

Specialty Orthopaedics, Norwest Private Hospital, G18/11 Norbrik Drive Bella Vista, Sydney, NSW, 2153, Australia.

Purpose: In contemporary total knee arthroplasty (TKA), most often, the goal is to align the femoral component to the epicondylar axis (EA). The posterior condylar axis (PCA) is easier to define than the EA, and thus the relationship of PCA to the EA is then used instead to align the femoral component to the EA. However, the relationship of PCA to EA is not constant and has been reported to differ between varus and valgus knees and with increasing deformity. Read More
