Peripheral Artery Disease I: Introduction01:30

Peripheral Artery Disease I: Introduction

Peripheral artery disease (PAD) predominantly results from atherosclerosis, which involves the accumulation of fatty deposits, or plaques, within the walls of arteries. This causes them to narrow and harden, significantly reducing blood flow. PAD predominantly affects the legs, particularly the arteries supplying the thighs and calves. In rare cases, it may involve other arteries, including those in the arms.Etiology of PAD:The principal cause of PAD is atherosclerosis, which results from fatty...
Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
Chronic Pancreatitis I: Introduction01:25

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...
Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
Ankle Joint01:10

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
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.
Synarthrosis
An immobile...

Area of Science:

  • Orthopedics
  • Rheumatology
  • Hand Surgery

Background:

  • Proximal interphalangeal (PIP) joint dysfunction significantly impacts hand function.
  • Arthritis affecting the PIP joint leads to considerable hand impairment.
  • PIP joint arthritides encompass nonerosive osteoarthritis (OA), erosive OA, posttraumatic arthritis, and inflammatory arthritis.

Purpose of the Study:

  • To review the different types of proximal interphalangeal joint arthritis.
  • To discuss the underlying mechanisms of these conditions.
  • To highlight the limitations in current treatment modalities.

Main Methods:

  • Literature review of proximal interphalangeal joint arthritides.
  • Classification of PIP joint arthritis types.
  • Discussion of etiological factors and pathogenesis.
  • Overview of existing treatment strategies.

Main Results:

  • Nonerosive OA results from mechanical stress, while erosive OA involves an inflammatory component.
  • The distinction between erosive and nonerosive OA is debated, with some viewing erosive OA as a more severe form of primary OA.
  • Inflammatory arthritis arises from connective tissue diseases, where normal joint use triggers damage.

Conclusions:

  • Proximal interphalangeal joint arthritis presents diverse forms with distinct etiologies.
  • Understanding the pathogenesis is crucial for managing hand impairment.
  • Current treatment options for PIP joint arthritis are limited, necessitating further investigation.
