Description

This book describes Hallux Varus, Diagnosis and Treatment and Related Diseases
Hallux varus is a medical disorder featured by medial deviation of the big toe at metatarso-phalangeal (MTP) joint.
Hallux varus is a relatively frequent foot deformity seen in clinics.
Since there is no good treatment, early diagnosis and changes in shoe wear are important
Causes
Infrequently, hallux varus is congenital.
Flexible hallux varus may be found in newborns and indicates their intrauterine positioning.
It returns to valgus in early childhood when walking starts
Congenital hallux varus is categorized into primary and secondary pathologic deformity.
Primary hallux varus is infrequent and linked to an overactive abductor hallucis.
Secondary hallux varus is linked to:
1. Big toe polydactyly,
2. A delta phalanx longitudinal epiphyseal bracket syndrome, and
4. Metatarsus adductus.
Adult acquired hallux varus deformity is often iatrogenic, often resulting from surgery for hallux valgus.
A patient may have problems in walking and wearing shoes.
Changing shoe wear is advantageous but many patients have significant deformity that necessitates surgery.
Mild hallux varus can be treated with stretching exercises and splints.
If the symptoms become significant and influence daily activities, then surgery should be indicated.
Surgery improves the overall position of the hallux but not necessarily its movement.
Salvage procedures may be necessary and corrective iatrogenic hallux varus procedures are 60% to 80% effective.
More often this deformity forms after a surgical intervention for hallux valgus because of:
1. Overcorrection,
2. Excessive lateral release,
3. Over-resection of medial eminence,
4. Over-plication of the medial capsule,
5. Zero-degree or negative inter-metatarsal angle, or immobilization of the toe in excess varus after surgery.
Other causes are:
1. Trauma and
2. Certain systemic inflammatory disorders such as psoriasis and rheumatoid arthritis.
The mechanism of arthropathies joins the destruction of the articular surfaces by distention of the joint capsule with:
1. Laxity of the collateral ligaments,
2. Intrinsic muscular contracture, and
3. Pannus.
Traumatic hallux varus happens with sports injuries due to rupture of the lateral collateral ligament and conjoined tendon.
Symptoms
Some patients have symptoms of the deformity and have problems in:

1. Wearing shoes,
2. Instability,
3. Decreased the range of movement, and
4. Weakness with push-off.
On physical examination, one can recognize varus orientation of the big toe.
There may be dorsal contraction of the MTP joint with or without IP joint contraction.
The extensor hallucis longus may be moved medially producing a bowstring deformity.
Medial sesamoid may be medially shifted.
The doctor should analyze the degree of extension of the first MTP joint and find out whether weight-bearing and the dynamics of ambulation worsen the deformity.
Non-operative treatment involves shoe stretching and modification.
Shoes with wide toe boxes and padding over bony prominences should be advocated.
For early postoperative varus deformities after hallux valgus correction surgery, the taping or splinting the toes can be successful.
If there is continual pain or inability to wear shoes, surgery is an indication.
Surgical treatment is dependent upon whether the deformity is flexible or rigid.
As a rule, the flexible deformity can be rectified with a soft tissue procedure.
The lengthening of the medial capsular structures may be adequate if the deformity is not too advanced.
For advanced but flexible deformities, the treatment is tendon transfers followed by inter-phalangeal osteotomy and arthrodesis.
