Fractures: Bone Repair01:27

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...
Flail Chest-I01:24

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...
Nondisjunction01:21

Nondisjunction

Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers.  Nondisjunction is common during anaphase I or anaphase II of meiosis.  Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
Nondisjunction01:29

Nondisjunction

During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
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...
Classification of Bones01:18

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...

Summary

Nonsurgical treatment is preferred for stable phalangeal fractures in elite athletes. Unstable fractures and unicondylar fractures often require surgical fixation for a faster return to sport.

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Traumatology

Background:

  • Phalangeal fractures are common injuries in athletes.
  • Treatment aims to restore function and enable early return to play.
  • Optimal management strategies vary based on fracture stability and location.

Purpose of the Study:

  • To outline the preferred management strategies for phalangeal fractures in elite athletes.
  • To discuss surgical techniques that facilitate early return to sport.
  • To highlight surgical indications for specific fracture patterns.

Main Methods:

  • Review of current treatment protocols for phalangeal fractures in elite athletes.
  • Discussion of surgical techniques including open reduction internal fixation (ORIF) with plate fixation and percutaneous headless compression screws.

  • Emphasis on techniques minimizing dissection and maximizing strength.

    • Main Results:

    • Nonsurgical management is recommended for stable, extra-articular proximal and middle phalangeal fractures, most distal phalanx fractures, and some nondisplaced intra-articular fractures.
    • Open reduction with internal fixation (plate fixation) is favored for unstable phalangeal shaft fractures.
    • Percutaneous headless compression screws are routinely used for unicondylar fractures.

    Conclusions:

    • The choice of treatment for phalangeal fractures in elite athletes depends on fracture stability and pattern.
    • Surgical interventions are crucial for unstable fractures to ensure rigid fixation and early range of motion.
    • Minimally invasive surgical techniques are preferred to expedite athlete recovery and return to competition.
