Diabetic Foot Ulcer01:31

Diabetic Foot Ulcer

33
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor.

Ankle Joint01:10

Ankle Joint

3.4K
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...

Pulse Assessment Sites01:11

Pulse Assessment Sites

3.5K
Pulse assessment sites are crucial in evaluating a patient's cardiovascular health. By assessing the pulsations of arteries at specific anatomical locations, healthcare professionals can gather valuable information about blood flow, heart rate, and peripheral circulation. Understanding these pulse assessment sites is essential for conducting comprehensive cardiovascular evaluations and monitoring patients' overall health. These sites are strategically chosen due to the accessibility and...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

14.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Muscles of the Leg that Move the Foot and Toes01:28

Muscles of the Leg that Move the Foot and Toes

5.1K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Knee Joint01:23

Knee Joint

3.4K
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...

Summary
This summary is machine-generated.

A 14-year-old boy experienced a toe swelling caused by Pigmented Villonodular Synovitis (PVNS). Surgical excision confirmed the diagnosis of this rare tumor affecting the extensor tendon.

Area of Science:

  • Orthopedics
  • Pathology
  • Oncology

Background:

  • Pigmented Villonodular Synovitis (PVNS) is a rare, benign neoplastic proliferation of the synovium.
  • It commonly affects large joints like the knee and hip, but can occur in smaller joints.
  • Foot and ankle involvement, particularly around tendons, is less common.

Purpose of the Study:

  • To report a case of Pigmented Villonodular Synovitis (PVNS) in a young male patient.
  • To highlight the clinical presentation and histopathological findings of PVNS in an unusual location.
  • To discuss the management of PVNS affecting the extensor hallucis longus tendon.

Main Methods:

  • A 14-year-old male presented with a dorsal great toe swelling.
  • The mass was surgically excised under subarachnoid block anesthesia.
  • Histopathological examination of the excised mass was performed.

Main Results:

  • The mass was golden brown and encircled the extensor hallucis longus tendon.
  • Histopathology confirmed the diagnosis of Pigmented Villonodular Synovitis (PVNS).
  • The patient's presentation and the tumor's location were consistent with PVNS.

Conclusions:

  • Pigmented Villonodular Synovitis (PVNS) can occur in the foot and ankle, even in pediatric patients.
  • Early diagnosis and surgical excision are crucial for managing PVNS.
  • This case underscores the importance of considering PVNS in the differential diagnosis of soft tissue masses around tendons.
