Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Imperfections in Crystal Structure: Point, Line and Plane Defects

Imperfections in Crystal Structure: Point, Line and Plane Defects

A perfect crystal, in theory, has a uniform structure with the same unit cell and lattice points throughout. However, any deviation from this periodic arrangement is known as an imperfection or defect. These defects can be categorized into three types: point, line, and plane defects.Point defects occur when there is a deviation from the ideal due to missing atoms, displaced atoms, or additional atoms. These imperfections might occur due to imperfect packing during crystallization or because of...

Herniated Intervertebral Disc l: Introduction

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Flail Chest-I

Flail Chest-I

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Functional Classification of Joints

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis
An immobile...

Area of Science:

Orthopedic Surgery
Hand and Wrist Trauma
Musculoskeletal Disorders

Background:

Perilunate dislocations and fracture dislocations are severe wrist injuries.
Inadequate treatment can lead to chronic pain, stiffness, and disability.

Purpose of the Study:

To emphasize the importance of prompt diagnosis and surgical intervention for perilunate injuries.
To highlight the benefits of anatomic reduction in carpal malalignment.

Main Methods:

Review of high-energy wrist injuries, focusing on perilunate dislocations and fracture dislocations.
Emphasis on the clinical significance of prompt surgical management and anatomic reduction.

Main Results:

Early recognition and surgical treatment with anatomic reduction correlate with better clinical success and patient satisfaction.
Radiographic evidence of arthrosis is common post-injury but does not consistently predict poorer patient function.

Conclusions:

Timely surgical intervention is key for favorable long-term outcomes in perilunate injuries.
Anatomic reduction of carpal malalignment is critical for optimizing patient function and satisfaction.
