Summary
Plain X-rays are effective for managing arrow injuries in low-resource settings, even for complex head injuries. This study shows successful retrograde extraction of a transorbital arrow using only X-ray imaging.
Area of Science:
- Neurosurgery
- Radiology
- Trauma Care
Background:
- The insurgency and farmer-herder crisis in northeast Nigeria have led to an increase in arrow injuries.
- Low-resource settings without functional computed tomography (CT) scans require reliance on plain X-rays for patient care decisions.
Observation:
- A patient presented with a right transorbital subfrontal arrow injury.
- Retrograde extraction of the arrow was performed based on plain X-ray findings.
Findings:
- The patient experienced no sequelae after the retrograde arrow extraction.
- Plain X-rays played a crucial role in guiding the management of this complex arrow injury.
Implications:
- Plain X-rays can be a valuable tool for managing arrow injuries in resource-limited environments.
- While CT is the gold standard, X-ray imaging provides essential diagnostic information when advanced imaging is unavailable.

01:19Impact Loading
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.

01:17Common Leveling Mistakes and Errors
A survey team is tasked with determining the elevation difference between points Point A and Point B, separated by uneven terrain. They use a leveling instrument and a leveling rod.Common MistakesMisreading the Rod: During a backsight reading at Point A, the instrumentman observes the rod partially obscured by tall grass. Instead of reading 1.135 m, they mistakenly record 1.735 m due to the misalignment of the crosshair with the wrong graduation. This error adds 0.600 m to all subsequent...
01:25Minor Losses in Pipes
In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...
