DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Procedures for Kidney StonesMedical intervention is necessary when kidney stones or renal calculi are too large to pass spontaneously (typically greater than 5 millimeters) when stones are accompanied by symptomatic infection (such as fever or pyelonephritis), when they impair kidney function, or when they cause persistent symptoms like severe pain, nausea, or urinary retention. Additionally, patients with only one kidney or those who cannot be treated with medical management also require...

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Foot and Ankle Surgery

Background:

  • The calcaneo-valgus deformity, characterized by a shortened lateral foot column, was described by Evans in 1975.
  • Surgical management aimed to correct this imbalance by equalizing the medial and lateral foot columns.

Purpose of the Study:

  • To review the surgical technique for calcaneo-valgus deformity correction.
  • To analyze the outcomes and complications associated with the calcaneal osteotomy procedure.

Main Methods:

  • The study describes Evans' osteotomy technique in the calcaneal neck, utilizing a tricortical bone graft.
  • The procedure aimed to equalize foot column lengths, with the osteotomy positioned 1.5 cm from the calcaneocuboid joint.

Main Results:

  • The osteotomy was initially successful but associated with complications such as sural nerve injury, wound dehiscence, undercorrection, and graft subsidence.
  • Despite complications, the procedure gained popularity and its indications expanded to other flatfoot conditions.

Conclusions:

  • Evans' calcaneal osteotomy provided a method for correcting calcaneo-valgus deformities.
  • While effective, the procedure's complications necessitated careful consideration and patient selection.
