Mitchell Bunion Procedure Wheeless
Wheeless' Textbook of Orthopaedics
this a distal "Step Cut" metatarsal osteotomy that displaces metatarsal head laterally in order to correct hallux valgus deformity and metatasus adductus;
- Mitchell procedure (Mitchell Osteotomy) is carried out more proximally than Chevron Osteotomy, & can correct more severe deformities than Chevron;
- this procedure is applicable to moderate to severe deformities of intermetatarsal angle and hallux valgus;

Morton's Neuroma Wheeless
Wheeless' Textbook of Orthopaedics
Morton's Neuroma: Interdigital Perineural Fibrosis
it is not a neuroma but a perineural fibrosis and it was not first accurately described by Morton but by Durlacher, a chiropodist in 1845; both Thomas G. Morton (1876) and Thomas K. Morton (1892) mistook it for a painful affection of the fourth MTP articulation
- it is a type of nerve compression syndrome which involves the common digital nerves of the lesser toes: most often 3rd (80-85 %) and less often the 2nd (15-20 %) interspace;
- interdigital neuromas do not occur in the 1st and 4th web space: consider other etiologies;
- the occurance of two interdigital neuromas is also very rare;
- occurs most often in middle aged women (78 % are women);

Pes Cavus Wheeless
Wheeless' Textbook of Orthopaedics
cavus deformity of the foot (elevated longitudinal arch) due to fixed plantar flexion of the forefoot;
- main type is the cavovarus and less frequent is the cavovarus;
- associated with spinal cerebellar degenerative dz;
- associated deformities: - claw toes

Plantar Fascitiis Wheeless
Wheeless' Textbook of Orthopaedics
one of several causes of heel pain;
- the pain is located somewhat more distally than in other causes of heel pain syndrome
- symptoms include gradual onset of pain at the origin of the plantar aponeurosis and 1 cm distal to this area
- no definitive evidence that plantar fasciitis is linked with abnormal foot posture (pes planus or pes cavus)

Polydactyly
Wheeless' Textbook of Orthopaedics
polydactyly in the foot usually involes a single duplication (hexadactyly)
- associated anomalies:
- duplications occur bilaterally in about 40-50% of patients, but often the duplications are not symmetric;
- polydactyly of hand occurs in about 1/3 of patients;
- syndactyly of the toes occurs in about 1/5 patients;
- Down's syndrome will be present in a minority of cases;

Polydactyly of the Foot eMedicine Orthopedics
eMedicine Cara Novick 2005
Synonyms and related keywords: duplicate toe, extra toe, duplicate digit, extra digit, forefoot anomaly, syndactyly, Ellis-van Creveld syndrome, trisomy 13, tibial hemimelia, trisomy 21
Polydactyly most commonly refers to the presence of 6 toes on one foot, but more toes are possible. Polydactyly may be associated with syndactyly. It most frequently occurs as an isolated trait with autosomal dominant inheritance and variable penetrance. Other patterns of inheritance, sporadic occurrence, and association with syndromes are also possible.

Proximal MT Osteotomy Wheeless
Wheeless' Textbook of Orthopaedics
indicated for moderate to severe deformities (HV angle of 13 to 20 deg);
- proximal osteotomy may be combined w/ other hallux valgus reconstructive procedures such as Silver procedure (resection of medial eminence) or a Mcbride type of soft tissue release;
- inadvertent dorsiflexion of the first metatarsal shold be avoided because this dorsiflexion will cause a dorsal bunion and transfer metatarsalgia to the second metatarsal;

Radiographic Evaluation of Hallux Valgus
Radiographic Evaluation of Hallux Valgus
Hallux valgus is a common foot disorder of several etiologies, which can lead to significant foot pain and deformity. Little has been published in the radiographic literature about the pre- and postoperative radiographic findings of this very common and very treatable cause of foot pain.

Surgery vs Orthosis vs Watchful Waiting for Hallux Valgus JAMA
A Randomized Controlled Trial
Markus Torkki, MD; Antti Malmivaara, MD,PhD; Seppo Seitsalo, MD,PhD; Veijo Hoikka, MD,PhD; Pekka Laippala, PhD; Pekka Paavolainen, MD,PhD JAMA. 2001;285:2474-2480.
Conclusions Surgical osteotomy is an effective treatment for painful hallux valgus. Orthoses provide short-term symptomatic relief.

Turf Toe Dislocation of MTP Great Toe Wheeless
Turf Toe is a tear of joint capsule from MT head which results in subluxation or dislocation of first MTP joint
- caused by hyperextension (most common), hyperflexion, or valgus injury;
- associated with decreased ROM at first MTP joint & its sequele can include hallux rigidus, and can exacerbate sesamoiditis;
