A variety of surgical procedures exist for repair of both traumatic and degenerative osseous and soft-tissue pathologic conditions involving the foot and ankle. It is necessary for the radiologist to be familiar with these surgical procedures, so as to assess structural integrity, evaluate for complicating features, and avoid diagnostic pitfalls. Adequate interpretation of postoperative changes often requires access to surgical documentation to evaluate not only the surgery itself but the expected timeline for resolution of normal postoperative changes versus progressive disease...

BACKGROUND: Lateralizing calcaneal osteotomy (LCO) is a frequently used technique to correct hindfoot varus deformity. Tibial nerve palsy following this osteotomy has been described in case reports but the incidence has not been quantified. METHODS: Eighty feet in 72 patients with cavovarus foot deformity were treated over a 6-year span by 2 surgeons at their respective institutions. Variations of the LCO were employed for correction per surgeon choice. A retrospective chart review analyzed osteotomy type, osteotomy location, amount of translation, and addition of a tarsal tunnel release in relation to the presence of any postoperative tibial nerve palsy...

The adult cavovarus foot exists on a spectrum and, therefore, requires a thorough evaluation to determine the extent of the deformity and then choose from a multitude of surgical procedures to achieve correction. Regardless of the severity of the deformity, treatment should include an algorithmic approach to adequately achieve a stable, balanced, and plantigrade foot. To prevent failure, the surgeon should evaluate whether the deformity is flexible or rigid, determine the location of the apex or apices of the deformity, evaluate any muscle imbalances occurring about the foot and ankle, and determine the need for additional procedures...

The orthopedic manifestations in patients with Charcot-Marie-Tooth disease include deformity and dysfunction of the extremities and spine. Conservative treatment is the first choice. Orthosis and rehabilitation can improve function, and are important for the prevention of joint contractures. Foot problems are most commonly observed and require surgical treatment. Foot deformities include pes cavus, cavovarus, claw toes, or drop foot. Single or combined surgeries selected for soft tissues are plantar release, tendon transfer, or Achilles tendon lengthening, and those for bones are osteotomies and joint fusions...

BACKGROUND: Charcot-Marie-Tooth disease (CMT), one of the most common hereditary neurologic disorders, often results in debilitating cavovarus foot deformities. The deformities are still not fully understood, and the treatment recommendations are consequently heterogeneous, often including calf muscle or Achilles tendon lengthening. METHODS: We examined 40 patients (80 feet) with CMT and bilateral cavovarus deformities (19 men and 21 women, mean age 33.6 ± 14...

Peroneal tendon pathology is a commonly reported cause of lateral ankle pain. The causes include cavovarus foot type, overuse, chronic tendinosis, peroneal subluxation or dislocation, acute traumatic split tears, and traumatic rupture. The purpose of the present report is to describe an alternative approach for surgical reconstruction of the peroneal tendons in patients when repair might no longer be effective. The use of a Hunter rod was originally described by Hunter in 1971 for 2-stage reconstruction of tendons in the hand...

INTRODUCTION: We describe a 6-year-old girl with a T118M PMP22 mutation and heterozygous deletion of PMP22 on chromosome 17 (17p11.2-p12) resulting in a severe sensorimotor polyneuropathy. METHODS: This study is a case report in which the relevant mutations are described. RESULTS: Foot pain, cavovarus feet, tibialis anterior atrophy, absent reflexes, and inability to walk were found when the patient was age 6 years. Nerve conduction studies showed evidence of a sensorimotor polyneuropathy and compressive mononeuropathies of bilateral median nerves at the wrist and ulnar nerves at the elbow...

Pedobarography is a common tool for the evaluation of foot deformity. We describe our radiographic and pedobarographic outcomes of surgical treatment of cavovarus foot deformity in children with Charcot-Marie-Tooth disease. Nineteen patients for a total of 30 feet were included. Preoperative and postoperative dynamic pedobarographic measurements were made and analyzed using the five-mask technique. Pedobarographic measures showed statistical significance for increased contact area and decreased peak forces in most mask areas after surgical treatment...

UNLABELLED: Calcaneal tuberosity osteotomies are commonly used to treat coronal plane deformities of the hindfoot. Assessing hindfoot alignment can be difficult and there is little evidence to guide the physician when considering the surgical treatment of these deformities. The indications for a calcaneal osteotomy are unclear in the literature because most of the published studies supporting their use are confounded by concurrent procedures such as in adult-acquired flatfoot correction or cavovarus reconstruction...

Calcaneal osteotomy is an extra-articular, joint-sparing procedure that is used in the correction of cavovarus and planovalgus foot deformity. Careful indications and contraindications for the procedure, with meticulous surgical technique, should be followed to avoid complications and to achieve optimal outcomes. Multiple options of osteotomies exist, including translational (medializing and lateralizing calcaneal osteotomy, with ability to slide proximally or distally, closing wedge (Dwyer), and rotational type osteotomies (Evans, Z-osteotomy)...

The subtle cavovarus foot (SCF) is a mild malalignment caused by either primary hindfoot varus or a plantarflexed first ray, resulting in a typical constellation of symptoms because of altered foot mechanics. Key clinical signs are a peek-a-boo heel and a positive Coleman block test. The cavovarus position places lateral ankle soft-tissue structures, such as the anterior talofibular ligament and the peroneal tendons, on stretch during normal gait. This can lead to common conditions such as lateral ankle instability, peroneal tendon tears, and stress fractures of the lateral metatarsals and cuboid...

In a 12-year old girl suffering from autosomal recessive axonal Charcot-Marie-Tooth (CMT) neuropathy, pes cavovarus was treated with botulinum toxin injection in the tibialis posterior. The patient underwent a clinical evaluation, video analysis of spatiotemporal gait parameters and dynamic foot plantar pressure assessment before treatment and then two weeks, three months and six months thereafter. The video gait analysis revealed a decrease in varus during the swing phase of gait. The dynamic foot plantar pressure decreased by 50% in the excessive pressure at the side of the foot six months after the injection (maximal pressure=42...

INTRODUCTION: The goal of this retrospective, multicentre study was to evaluate the long-term outcomes in patients who have undergone partial or total arthrodesis of the subtalar and midtarsal joints. HYPOTHESIS: Secondary osteoarthritis of the adjacent joints can negatively affect the outcomes more than 10 years after these fusion procedures. MATERIAL AND METHODS: The outcomes of 72 fusions (total: 22; partial: 50) performed between 1981 and 2002 were evaluated using the Maryland Foot Score (MFS), self-evaluation questionnaire and three weight-bearing X-ray views (Meary's with cerclage wire around heel, lateral and dorsoplantar)...
