Summary
Endoscopic accessory navicular (AN) resection effectively treats symptomatic AN, significantly improving patient pain and function. This minimally invasive procedure shows good outcomes with minimal complications.
Area of Science:
- Orthopedic Surgery
- Foot and Ankle Surgery
- Minimally Invasive Procedures
Background:
- Symptomatic accessory navicular (AN) can cause significant foot pain and dysfunction.
- Surgical intervention is considered for persistent symptoms unresponsive to conservative treatment.
Purpose of the Study:
- To evaluate the clinical outcomes of endoscopic accessory navicular (AN) and partial navicular resection.
- To assess the efficacy and safety of this minimally invasive approach for symptomatic AN.
Main Methods:
- Retrospective review of medical records for patients with type 2 symptomatic AN.
- Analysis of clinical, radiographic, and patient-reported outcomes after endoscopic surgery.
- Mean follow-up duration of 39.5 months in 29 patients.
Main Results:
- Significant improvement in visual analog scale (VAS) pain scores (74.6 to 5.4).
- Substantial enhancement in Japanese Society for Surgery of the Foot (JSSF) scores (63.0 to 95.9).
- One case of wound dehiscence; no other major complications reported. Postoperative imaging showed tendonlike tissue filling the resected space.
Conclusions:
- Endoscopic accessory navicular (AN) and partial navicular resection is an effective treatment for symptomatic AN.
- The procedure yields good patient outcomes with a low complication rate.

01:27Fractures: 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...

01:10Ankle Joint
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...
