What is a Bunion? A bunion (also referred to as hallux valgus or hallux abducto valgus) is often described as a bump on the side of the big toe. But a bunion is. A bunion is a deformity of the joint connecting the big toe to the foot. The big toe often bends Synonyms, Hallux abducto valgus, hallux valgus, metatarsus primus varus. Hallux Valgus-Aspect pré op Specialty · Orthopedics. Hallux valgus causes pain particularly in the bunion on the inner side of the foot, Interventions for treating hallux valgus (abductovalgus) and bunions.

The larger part of the bump is a normal part of the head of the first metatarsal bone that has tilted sideways to stick out at its distal far end.

Acquaintance with the various surgical procedures and the indications for each particular method. A V-shaped cut is made in the head of metatarsal I and the bone is displaced laterally by one third to a half of its width, thus correcting the intermetatarsal angle.

Occasionally the joint surface at the head of metatarsal I is tilted to lateral, particularly in cases where the hallux valgus arose before the patient reached adulthood. Fixation is achieved preferably with a dorsal plate Figure 6b.

The tarsus and hindfoot must also be investigated to exclude accompanying deformities. Associated lesser toe deformities, such as hammertoes, cross-over toe deformities, and transfer metatarsalgia pain, should be evaluated for as well. The algorithm used at our institution to classify hallux valgus and select the most appropriate surgical procedure.

At the same time, osteotomies in two planes provide greater stability, because the bony contact surface is increased and the danger of dislocation reduced.

Pathologic anatomy of hallux abducto valgus.

Viruses acquired abroad—what does the primary care physician need to know? Views Read Edit View history. Hallux valgus can also be treated surgically in the presence of chronic polyarthritis or other rheumatic diseases, although care must be taken to select an appropriate procedure. Permanent correction, loss of mobility, subsequent osteoarthritis.


The Treatment of Hallux Valgus

Hueter 15Mayo e6. Therefore, although the guideline is formulated in quite general terms, its recommendations essentially correspond to those given here. A radiograph with the patient in standing position shows the angle between metatarsal I and metatarsal II, as well as the congruence of the first metatarsophalangeal joint and any signs of osteoarthritis. Fixation with a small implant is necessary to prevent reposition loss, but an inexpensive anductus screw or a wire will suffice.

In case of osteoarthritis, and in elderly patients, a resection arthroplasty is preferred; arthrodesis is performed in physically active patients.

See the following website: During this time the patient has to wear a flat-soled healing shoe that allows abducus weight bearing. After correction the osteotomy has to be stabilized with an implant. Because it is the part of the body most distant from the heart, the foot is the first place where decreased perfusion will make itself noticed. At present there are many different bunion surgeries for different effects.

Disadvantage of some operative techniques.

This is hallx by other foot muscles and ligaments, however, so that overall the forces are balanced. In our experience the patients are moving around normally without special shoes within 4—6 weeks.

Simple technique, loss of hallux function, transfer metatarsalgia frequent. Investigation of peripheral vascular perfusion and motor and sensory functions is obligatory.

Although hallux valgus is particularly frequent from the middle years of life upwards, many patients of both sexes are affected at a young age, usually in one foot but sometimes in both 1 — 3e1 — e3. Cochrane Database Syst Rev.

Postoperatively the toe must be held straight for 6 weeks with a corrective bandage. The soft tissue covering of the foot is extremely thin, and this hampers wound healing. Osteochondral Lesions of the Talus. J Am Podiatr Med Assoc.

Prospective, randomized comparison of proximal crescentic and proximal chevron osteotomies for correction of hallux valgus deformity. They become displaced, usually upwards, leading to pressure against the shoe. Absolutely accurate restoration of the angle is not possible, but if the wedge has a base of 1 to 3 mm the correction is usually adequate. The simplest are opening osteotomies that are then filled medially with bone, for example from the resected exostosis.


June Learn how and when to remove this template message. Severe deformities require a soft-tissue procedure at the first metatarsophalangeal joint and a proximal first metatarsal osteotomy.

Ferri’s Differential Diagnosis E-Book: Arthrodesis of the first metatarsophalangeal joint is utilized for severe deformities, spastic or rigid deformities, and associated arthritis. Hardware may even include absorbable pins that perform their function and are then broken down by the body over the course of months.

Furthermore, perfusion is poorest in the foot because of its distance from the heart. Author information Article notes Copyright and License information Disclaimer. Complicated and costly implants staples, screws are available, but adequate fixation can be achieved with a simple, inexpensive suture threaded through drill holes.

Screw versus K-wires for stabilization; curved, distal metatarsal osteotomy. This shows the limits of current scientific knowledge, particularly when it comes to detailed questions of surgery.

The surgical treatment of bunions and hallux valgus. The deformity can often be attributed to ill-fitting shoes, and sometimes there is a familial disposition.

Atop of the first metatarsal head either medially or dorso-medially, there can also arise a bursa that when inflamed bursitiscan be the most painful aspect of the process.
