Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

13.4K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

2.7K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

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.

Glucose Transporters01:27

Glucose Transporters

28.1K
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Muscles of the Shoulder01:23

Muscles of the Shoulder

9.7K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...

Glaucoma: Overview01:25

Glaucoma: Overview

1.6K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Summary
This summary is machine-generated.

Glenoid dysplasia, a scapular anomaly, involves bone deficiency and can lead to shoulder instability and arthritis. Treatment options vary, with challenges in achieving long-term success.

Area of Science:

  • Orthopedics
  • Developmental Biology
  • Radiology

Background:

  • Glenoid dysplasia is a congenital scapular anomaly characterized by posteroinferior glenoid and scapular neck bone deficiency.
  • It may arise as an isolated condition or be associated with genetic syndromes, potentially linked to defective ossification.
  • Radiographic findings often show bilateral, symmetric scapular neck dysplasia with varied bony alterations.

Purpose of the Study:

  • To review the characteristics, clinical implications, and management challenges of glenoid dysplasia.
  • To highlight the association between glenoid dysplasia and shoulder joint complications.
  • To discuss the efficacy and limitations of current treatment strategies.

Main Methods:

  • Literature review of studies on glenoid dysplasia.
  • Analysis of radiographic features and clinical presentations.
  • Evaluation of treatment outcomes for nonsurgical and surgical interventions.

Main Results:

  • Glenoid dysplasia is linked to shoulder instability and early-onset glenohumeral arthritis.
  • Compensatory glenoid labral hyperplasia can delay or reduce symptom severity.
  • Nonsurgical management shows some success in younger individuals, but degenerative changes are common.
  • Anatomic arthroplasty may yield favorable results, yet subluxation and component failure remain concerns.

Conclusions:

  • Glenoid dysplasia presents a complex orthopedic challenge with variable clinical outcomes.
  • Effective long-term management strategies are needed to address instability and degenerative joint disease.
  • Further research into novel treatment approaches is warranted for improved patient prognoses.
