Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

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...
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...

Valgus extension overload causes elbow injuries in athletes, leading to pain and potential damage to the olecranon and trochlea. Early diagnosis and appropriate management, including evaluating ligament stability, are crucial for recovery.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanics

Background:

  • Valgus torque and deceleration generate significant forces on the elbow's posteromedial structures.
  • This mechanism, termed valgus extension overload, is implicated in various elbow pathologies.

Purpose of the Study:

  • To describe the biomechanics of valgus extension overload.
  • To outline the resulting olecranon and trochlea pathologies.
  • To discuss diagnostic and treatment strategies.

Main Methods:

  • Review of clinical and basic science research on valgus extension overload.
  • Description of the biomechanical forces involved.
  • Correlation of these forces with observed pathologies and symptoms.

Main Results:

  • Valgus extension overload can lead to chondromalacia, osteochondrosis, fractures, and exostosis of the olecranon and trochlea.
  • Posteromedial elbow pain during deceleration is a key symptom.
  • Radiography and CT scans aid in identifying loose bodies and fragmentation.

Conclusions:

  • Comprehensive evaluation for medial ulnar collateral ligament insufficiency is essential in patients with valgus extension overload.
  • Surgical treatment should be conservative, focusing on osteophyte resection without compromising normal olecranon anatomy.
