Distraction-like phenomena in maxillary bone due to application of orthodontic forces in ovariectomized rats

open access: yesIndian Journal of Dental Research, 2012
Background: Orthodontic forces may not only influence the dentoalveolar system, but also the adjacent and surrounding cortical bone. Aim: Since there is very limited information on this issue, we aimed to study the possible changes in maxillary ...

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Limb lengthening by callus distraction (callotasis) [PDF]

open access: yes, 1987
Callotasis is a new technique of limb lengthening involving slow distraction of the callus formed in response to a proximal submetaphyseal corticotomy. Using a dynamic axial fixator with telescoping capabilities, distraction begins after 2 weeks.

Characterization of the Developing Lacunocanalicular Network During Fracture Repair

open access: yesJBMR Plus, 2021
Fracture repair is a normal physiological response to bone injury. During the process of bony callus formation, a lacunocanalicular network (LCN) is formed de novo that evolves with callus remodeling.

Biportal Endoscopic Posterior Open‐Window Focal Debridement and Lavage for Sacroiliac Joint Tuberculosis

open access: yesArthroscopy Techniques, EarlyView.
Abstract Sacroiliac joint tuberculosis (SJT), although relatively uncommon, may lead to severe destruction and functional impairment of the sacroiliac joint. Surgical intervention is recommended for patients with significant joint destruction, mild cystic changes, or sacroiliac joint instability. Early bone fusion may be facilitated through drainage of

Comparative Study of Interlocking Nailing and Kuntscher Nailing with Adjuvant Plating for the Treatment of Femur Shaft Fractures

open access: yesAdvances in Human Biology, 2016
Aim: To compare the results of this study with an alternate method of Kuntscher nailing with adjunctive plating for the treatment of femoral shaft fractures in terms of operative parameters, limb mobilization, radiation exposure and fracture union ...

Neurovascular coupling in bone regeneration: Mechanisms, advanced biomaterials and challenges

open access: yesBMEMat, EarlyView.
This figure illustrates various material strategies for neurovascularized bone regeneration, including electroactive scaffolds, ion‐loaded materials, drug delivery systems, surface modifications, cells/cell products, growth factors, and peptides. These approaches aim to synergistically promote the regeneration of neural, vascular, and bone tissues ...

Harnessing blood clot as a native scaffold for orchestrating tissue repairs and regeneration

open access: yesBMEMat, EarlyView.
The blood clot, owing to its dynamic composition and unique microenvironment, holds significant yet underappreciated potential for tissue engineering. This review systematically summarizes the pathophysiology of clot formation, the key regulatory factors shaping its microenvironment, and its applications in both pre‐clinical and clinical settings ...

Exogenous PTHrP Repairs the Damaged Fracture Healing of PTHrP+/− Mice and Accelerates Fracture Healing of Wild Mice [PDF]

open access: yes, 2017
Bone fracture healing is a complicated physiological regenerative process initiated in response to injury and is similar to bone development. To demonstrate whether an exogenous supply of parathyroid hormone–related protein (PTHrP) helps in bone fracture
