Delayed healing of a navicular stress fracture, following limited weight-bearing activity

Biomechanical concepts of fracture healing in weight-bearing long bones.

Fracture healing is a complex process in which mechanical forces are essential for the regeneration of bone tissue. Mechanical loading can induce osteogenesis through the process of mechanotransduction. Current data on how mechanical loading stimulates fracture healing in weight-bearing long bones are presented. The role of mechanosensors, loading-induced interstitial fluid flow, streaming pote...

Stress fracture of the navicular bone.

Navicular stress fractures in athletes are notoriously difficult to diagnose, resulting in an average delay in diagnosis of 4 months after the onset of symptoms. There are various reasons for this delay. Navicular stress fractures are characterised by an unspecific symptomatology combined with a paucity of physical findings. Furthermore there is difficulty in visualising stress fractures on pla...

Acute and Delayed Stress Symptoms Following Snakebite

Background: Overwhelming life experiences can trigger stress disorders including acute stress disorder (ASD) and post-traumatic stress disorder (PTSD). The objective of this study was to investigate the frequency of and predictive factors for ASD and PTSD in snakebite victims. Methods: In this study, snakebite victims who were admitted to Mashhad Medical Toxicology Centre, Imam Reza Hospital, I...

Immediate Weight-Bearing after Ankle Fracture Fixation

We believe that a certain subset of surgical ankle fracture patients can be made weight-bearing as tolerated immediately following surgery. Immediate weight-bearing as tolerated (IWBAT) allows patients to return to ambulation and activities of daily living faster and may facilitate rehabilitation. A prospectively gathered orthopaedic trauma database at a Level 1 trauma center was reviewed retro...
