AI Article Synopsis

  • Os vesalianum pedis (OVP) is a rare bone in the foot near the 5th metatarsal that is usually asymptomatic but can sometimes cause lateral foot pain and mimic an avulsion fracture.
  • A case involving a 62-year-old man showed that his OVP was initially misdiagnosed as an avulsion fracture after he suffered an inversion injury.
  • Treatment for OVP is generally conservative, though surgery may be required if non-surgical methods fail, highlighting the importance of correctly diagnosing it to avoid unnecessary procedures.

Article Abstract

Introduction: Os vesalianum pedis (OVP) is a rare accessory ossicle of the foot located proximal to the base of 5th metatarsal. It is usually asymptomatic but can mimic an avulsion fracture of proximal 5th metatarsal and is an infrequent cause of lateral foot pain. There have only been 11 cases of symptomatic OVP reported in the current literature.

Case Report: Our patient, a 62-year-old male presented with lateral foot pain following an inversion injury of his right foot, with no history of any previous trauma. What was initially mistaken as an avulsion fracture of the 5th metacarpal base was later revealed to be an OVP on contralateral X-ray.

Conclusion: Treatment is mostly conservative, but surgical excision can be done in cases following failed non-operative treatment. In the context of trauma, OVP must be differentiated from other causes of lateral foot pain such as Iselin's disease and avulsion fractures of base of 5th metatarsal. Understanding the various etiologies of the condition and what those etiologies are usually related to can help prevent unnecessary treatment.

Background: The foot is an essential organ for human locomotion. Assessment of plantar pressure distribution could provide key clinical information on foot functions. However, the mechanism that links body mass index to injury is not clear.

Purpose: This study aimed to compare the distribution of plantar pressure and anterior-posterior (AP) or medial-lateral (ML) shear forces in healthy younger (HY) people, healthy older (HO) people, and diabetic patients, both in static standing and during gait.

Materials And Methods: A total of 20 HY adults, 16 HO adults and 15 diabetic patients were included. The static mechanical distribution measurements included: static horizontal, AP slope plane, and left/right slope standing.

New Minimally Invasive Bunion Surgery: The End-All Be-All Bunion Repair?

Clin Podiatr Med Surg

January 2025

Private Practice, Blitz Footcare, 800A 5th Avenue, Suite 403, New York, NY 10065, USA; Private Practice, Blitz Footcare, 435 N. Roxbury Drive, Penthouse, Beverly Hills, CA 90210, USA. Electronic address:

The revival of "new" minimally invasive bunion surgery (MIBS) is made possible as a laparoscopic-like fluoroscopically guided procedure using new instrumentation, advanced osseous realignment techniques and procedure-specific orthopedic hardware. Bunions of all severities can be treated with MIBS with a functional walking recovery in a small surgical shoe. Realignment occurs through a subcapital osteotomy with metatarsal head shifts that are stabilized by a single or dual metatarsal MIBS screw(s) that span a resultant osseous defect.

Article Synopsis
  • This study examines the outcomes of two different screw types used for treating fifth metatarsal fractures in elite athletes, specifically headless vs. headed screws.
  • Researchers collected data from 40 athletes treated between 2016 and 2022 and compared factors like time to bone healing, return to play, and complications.
  • Results showed similar healing times and return rates for both groups, indicating that both screw types are effective, but further analysis is necessary to assess other potential advantages of headless screws.

Effect of patient age on fifth metatarsal fracture pattern, management, and outcomes.

Article Synopsis
  • This study examined how age affects the clinical outcomes and management of 5th metatarsal fractures in patients from a large urban hospital over ten years.
  • It found that older patients (65 years and up) were more likely to have metatarsal neck fractures, while younger patients had more Zone 1 base fractures.
  • Despite these differences in fracture types, both age groups had similar healing times, indicating that age does not significantly affect recovery outcomes.
