Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...
Dissociative Disorders01:27

Dissociative Disorders

Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.
Dissociative Fugue
A hallmark feature of dissociative disorders is the dissociative fugue...
Dissociative Identity Disorder01:30

Dissociative Identity Disorder

Dissociative Identity Disorder (DID), previously termed multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states. Each identity exhibits unique patterns of behavior, voice, and mannerisms and may possess separate memories and emotional responses. The alternating control between identities can result in memory gaps and challenges in recalling daily activities, often exacerbating the individual's...
Functional Classification of Joints01:09

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.

Herniated Intervertebral Disc l: Introduction01:29

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...
Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Summary
This summary is machine-generated.

Carpal instability nondissociative (CIND) involves wrist joint kinematic dysfunction without bone disruption within carpal rows. Treatment varies by subcategory, including surgery or nonsurgical management for different CIND types.

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Biomechanics

Background:

  • Carpal instability nondississociative (CIND) is a spectrum of kinematic dysfunctions in the proximal carpal row.
  • CIND presents with a characteristic wrist "clunk" at the midcarpal or radiocarpal joints.
  • It is differentiated from carpal instability dissociative (CID) by intact carpal row bone alignment.

Purpose of the Study:

  • To categorize and describe the subcategories of carpal instability nondissociative (CIND).
  • To outline the clinical manifestations and diagnostic considerations for CIND.
  • To review current and potential treatment strategies for each CIND subcategory.

Main Methods:

  • Review of existing literature on carpal instability nondissociative.
  • Classification of CIND into four subcategories: palmar, dorsal, combined, and adaptive.
  • Summary of surgical and nonsurgical treatment options for each subcategory.

Main Results:

  • Palmar CIND involves instability across the proximal carpal row, treated surgically if conservative measures fail.
  • Dorsal CIND features capitate subluxation, typically managed non-surgically, with surgery for refractory cases.
  • Combined CIND presents with features of both palmar and dorsal instability, addressed by soft-tissue or bony procedures.
  • Adaptive CIND involves slackened volar ligaments, treated with corrective osteotomy to restore distal radius volar tilt.

Conclusions:

  • Carpal instability nondissociative encompasses diverse kinematic dysfunctions requiring tailored treatment approaches.
  • Understanding the subcategories of CIND is crucial for effective clinical management.
  • Treatment strategies range from conservative measures and soft-tissue repairs to bony procedures and osteotomies.
