This document discusses avascular necrosis (AVN), including:
- Causes of AVN such as corticosteroid use, alcohol abuse, and trauma
- Management involves early diagnosis via imaging like MRI and treatment based on staging, with options ranging from observation to core decompression and bone grafting for pre-collapse cases or osteotomy for some post-collapse cases
- Surgical techniques are described for core decompression with or without bone grafting to improve blood flow and support the femoral head, as well as various osteotomies to redistribute weight bearing for some collapsed cases
- Case studies demonstrate outcomes of these treatments in preserving femoral heads or delaying total hip replacement
Rheumatoid arthritis is a chronic inflammatory disease that commonly affects the small joints of the hands and feet. It results from an autoimmune response causing synovial inflammation and destruction of articular cartilage and bone. Early radiographic signs include soft tissue swelling, joint space widening, and juxta-articular osteopenia. Later findings consist of joint space narrowing, erosions, subluxations, and bony ankylosis. MRI is the best imaging modality for detecting early synovitis, bone marrow edema, and erosions. Characteristic sites of involvement include the second and third MCP and PIP joints bilaterally.

Detailed explanation about balance and balance training.
Balance refers to an individuals ability to maintain their line of gravity within their Base of support (BOS). It can also be described as the ability to maintain equilibrium, where equilibrium can be defined as any condition in which all acting forces are cancelled by each other resulting in a stable balanced system.
BALANCE SYSTEMS:
The following systems provides input regarding the body's equilibrium and thus maintains balance.
Somatosensory / Proprioceptive System
Vestibular System
Visual System
The Central Nervous System receives feedback about the body orientation from these three main sensory systems and integrates this sensory feedback and subsequently generates a corrective, stabilizing torque by selectively activating muscles. In normal condition, healthy subjects rely 70% on somatosensory information and 20% Vestibular & 10% on Vision on firm surface but change to 60% vestibular information, 30% Vision & 10% somatosensory on unstable surface.
SOMATOSENSORY SYSTEM:
Proprioceptive information from spino-cerebellar pathways, processed unconsciously in the cerebellum, are required to control postural balance. Proprioceptive information has the shortest time delays, with monosynaptic pathways that can process information as quickly as 40–50 ms and hence the major contributor for postural control in normal conditions.
VESTIBULAR SYSTEM:
The vestibular system generates compensatory responses to head motion via:
Postural responses (Vestibulo-Spinal Reflex) - keep the body upright and prevent falls when the body is unexpectedly knocked off balance.
Ocular-motor responses (Vestibulo-Ocular Reflex) - allows the eyes to remain steadily focused while the head is in motion.
Visceral responses (Vestibulo-Colic Reflex) - help keep the head and neck centred, steady, and upright on the shoulders.
VISUAL SYSTEM:
For non-impaired individuals, under normal conditions the contribution of visual system to postural control is partially redundant as the visual information has longer time delays as long as 150-200 ms.
Friedrich et al. observed that adults with visual disorders were able to adapt peripheral, vestibular, somatosensory perception and cerebellar processing to compensate for their visual information deficit and to provide good postural control.
In addition, Peterka found that adults with bilateral vestibular deficits can enhance their visual and proprioceptive information even more than healthy adults in order to reach effective postural stability.
The influence of moving visual fields on postural stability depends on the characteristics of the visual environment, and of the support surface, including the size of the base of support, its rigidity or compliance.
TYPES OF BALANCE:
Balance can be classified in to :
Static Balance:
Dynamic Balance
A normal spine has three curves that are important for balance and posture. Forward head posture occurs when the cervical spine curve is straightened or reversed, causing the head to jut forward. This is common for people who spend a lot of time hunched over desks or devices. Forward head posture can lead to arthritis, pain, limited neck mobility, and increased risk of muscle strain. Preliminary research also links correcting forward head posture to reduced ADHD symptoms in some cases. Chiropractic care involving adjustments can help remove vertebral subluxations associated with forward head posture and improve pain and head position. Adopting proper seated posture and limiting heavy backpack weight can also help reduce risks of developing forward head posture.

Cervical radiculopathy is pain in an arm caused by compression of a cervical nerve root. It is commonly caused by cervical spondylosis which results in decreased disc height and bone spurs around the vertebrae that can compress nerve roots. Physical exam findings may include pain and sensory changes in the arm corresponding to the affected nerve root level as well as weakness or reflex changes. Diagnosis is based on history, physical exam, and imaging such as MRI which is the most sensitive test for evaluating soft tissues like discs and nerves. Most cases improve over time but surgery may be needed if conservative treatment fails.

Glossário Essencial de Problemas NeuromotoresJoaquim Colôa
Este documento é um glossário de termos neuromotores elaborado por Joaquim Colôa em 2006/2007. Contém definições concisas de termos relacionados a movimentos, reflexos e condições neurológicas, começando pelas letras A a R. As definições variam de um a alguns parágrafos e abordam conceitos como adução, abdução, atetose, ataxia, distonias, hemiparésia e vários reflexos presentes no desenvolvimento infantil.
Thoracolumbar braces are commonly used to treat adolescent idiopathic scoliosis. While braces aim to control curve progression through applied forces over time, their effectiveness is disputed due to inconsistent patient populations and evaluation methods across studies. Ideal candidates are those with curves between 30-40 degrees or less than 30 degrees who are at high risk of progression. Studies found braces successful in preventing progression over 6 degrees in right thoracic curves 25-35 degrees. However, wrong indications or inadequate forces can lead to treatment failure. Further research on brace biomechanics aims to better understand correction effects and pressure distributions to optimize brace design and prescription.

O plexo braquial é um conjunto de 5 raízes nervosas (C5, C6, C7, C8 e T1) que se originam na região cervical e formam um emaranhado nervoso que segue próximo à região da clavícula.
A união destas raízes origina troncos e fascículos nervosos que posteriormente darão origem aos principais nervos responsáveis pela inervação sensitiva e motora dos membros superiores. Estes nervos são importantes para os movimentos e sensibilidade do braço, antebraço e mão.
The cervical spine functions to house and protect the spinal cord, support the head and facilitate movement. It has a normal anterior curvature of 20-40 degrees. Non-palpable structures include the cranium, mandible, and vertebrae. Palpable structures are the superior nuchal line, external occipital protuberance, mastoid process, and vertebral levels C3-C6. Typical cervical vertebrae have transverse processes and spinous processes while C1-C2 are atypical. The intervertebral discs act as shock absorbers between vertebrae. Key joints are the atlanto-occipital and atlanto-axial, which allow nodding and rotation. Ligaments
