PES surgery, or Posterior Element Surgery, is not explicitly defined in the provided reference. However, the reference describes a surgical procedure for acquired pes planovalgus that involves a calcaneal osteotomy, which is part of the treatment plan that may be used in conjunction with posterior element surgery. To clarify, we can refine the question to be, "What types of surgical procedures are used to treat acquired pes planovalgus and what is the goal of these surgeries?" Based on the provided reference we can answer this revised question.
Surgical Procedures for Acquired Pes Planovalgus
Acquired pes planovalgus, also known as adult-acquired flatfoot, is a condition where the arch of the foot collapses. Surgical interventions aim to correct the deformity and alleviate associated symptoms.
Key Goals of Surgery
- Correcting the foot deformity: This involves restoring the natural arch of the foot.
- Decreasing strain on ligaments: Specifically, surgery aims to reduce tension on the spring and deltoid ligaments, which support the arch.
- Protecting soft-tissue reconstruction: This helps ensure that repairs to the ligaments and other soft tissues remain intact and stable.
Surgical Techniques
One described procedure in the reference is an osteotomy of the calcaneus, which is the heel bone. This procedure has multiple goals:
- Medial and Inferior Displacement: The osteotomy involves moving the posterior third of the calcaneus medially (inward) and inferiorly (downward). This repositioning helps realign the foot and reduce strain on supporting ligaments.
Here is an overview:
| Procedure | Goal | Details |
|---|---|---|
| Calcaneal Osteotomy | Correct foot deformity, reduce ligament strain, protect soft-tissue reconstruction | Medial and inferior displacement of the posterior third of the calcaneus. |
Considerations
- Individualized Approach: The specific surgical approach is tailored to each patient's unique condition and needs.
- Comprehensive Treatment: Surgery may be combined with other non-surgical treatment options, like orthotics or physical therapy, as part of a comprehensive treatment plan.
