[Screw Angle and Condylar Ratio as Possible Parameters to Monitor the Treatment of Idiopathic Axial lower Limb Deformities Using Eight-Figure Plates].
Acta Chir Orthop Traumatol Cech
January 2025
Klinika dětské chirurgie, ortopedie a traumatologie Fakultní nemocnice Brno.
Purpose Of The Study: Temporary hemiepiphyseodesis using figure-eight plates is currently one of the main surgical techniques to correct axial deformities of lower limbs in paediatric patients. Comprehensive analysis, correct indication and monitoring of treatment are the basic prerequisites for successful therapy. The aim of the study was to analyse parameters that could become an alternative to standard parameters used nowadays, namely the inserted screw angle (SA), and a new parameter - condylar ratio (CR).

Acta Chir Orthop Traumatol Cech
January 2025
Ortopedická klinika, Fakultní nemocnice Hradec Králové.
Purpose Of The Study: The preclinical study aimed to compare the healing of segmental bone defects treated with biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel with the established autologous spongioplasty. Another aim was to evaluate the hydrogel as a scaffold for osteoinductive growth factor of bone morphogenetic protein-2 (BMP-2) and stem cells.
Material And Methods: The study was conducted in an in vivo animal model.
Manubriosternal Morphology of Anthropoid Primates.
Am J Biol Anthropol
January 2025
Department of Pathology and Anatomical Sciences, M263 Medical Sciences Building, University of Missouri, Columbia, Missouri, USA.
Objectives: The purpose of this paper is to examine the proportions of the manubrium and sternebrae across anthropoid primates to explore variation hypothesized to be related to thoracic shape and locomotor specialization, and to determine whether the sternoclavicular joint orientation in hominoids reflects hypothesized differences in shoulder joint positioning relative to the thorax.
Materials And Methods: Metric data and sternoclavicular joint orientation data were collected from calibrated photographs of manubria and sternebrae from a large sample (n = 244) of extant anthropoid primates, as well as a small sample of fossil taxa. Manubriosternal and rib cage metric data were also collected from CT scans of an additional 52 extant anthropoid torsos.
Implant failure of the Compress prosthesis: a case report.
J Med Case Rep
January 2025
Department of Orthopaedic Surgery, Nagoya University Graduate School of Medicine, Nagoya University Hospital, 65 Tsurumai, Showa, Nagoya, Aichi, 466-8550, Japan.
Background: The Compress is designed to achieve bone formation and stability by applying pressure at the bone-implant interface, minimizing the likelihood of aseptic loosening, which is a complication of stem implants. Herein, we report two cases of implant failure using the Compress.
Case Presentation: Case 1 describes a 36 year-old Japanese man who underwent extraarticular tumor resection, Compress arthroplasty, and reconstruction with a gastrocnemius flap after preoperative chemotherapy for a secondary malignant giant cell tumor in the right distal femur.
Prevalence and risk factors of concomitant malleolar and fibular fractures in patients with distal spiral tibial shaft fractures.
Eur J Trauma Emerg Surg
January 2025
Department of Orthopaedics, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, Beijing, China.
Purpose: (1) To evaluate the incidence and combination types of concomitant malleolar and fibular fractures in patients with distal spiral tibial shaft fractures. (2) To evaluate the risk factors for concomitant malleolar fractures in patients with distal spiral tibial shaft fractures.
Methods: A retrospective review was performed on 64 cases of surgically treated distal spiral tibial shaft fractures with complete radiographs and computed tomography (CT) scans.
