Objectives: Extra-articular posteromedial talocalcaneal coalition (EA-PM TCC) accounts for approximately one-third of TCC, but its radiographic features are not well-described. The current study aims to compare the radiographic features of EA-PM TCC with normal ankles and with the commoner forms of TCC.

Materials And Methods: A retrospective review of cases of TCC over 12 years for whom radiographs, CT, and/or MRI study were available. Read More

Objective: To explore CT imaging features and reason for missed diagnosis of clinical practice of occult anterior calcaneal process fracture.

Methods: From July 2013 to November 2018, the clinical data of 13 patients with occult an anterior calcaneal process fracture were retrospectively analyzed, including 2 males and 11 females, aged from 22 to 54 years old. Classification of fracture, displacement of fracture, direction of fracture line, size of fracture, with or without tarsal coalition, other fractures and misdiagnosis, the time from injury to diagnosis, condition of treatment and fracture healing were observed according to case history, data of X-ray and CT.

Objective: The purposes of this study was to determine the prevalence of the accessory anterolateral talar facet (AALTF); to evaluate the relationship between AALTF, focal abutting bone marrow edema (FABME), and sinus tarsi edema; and to study the prevalence of tarsal coalitions in patients with the AALTF utilizing ankle MR images.

Materials And Methods: 5-T ankle MR images were reviewed for the presence of AALTF, FABME, sinus tarsi edema, tarsal coalition, and location and type of coalition (cartilaginous, fibrous, and osseous). Multivariate analysis was performed to examine the correlation between AALTF and the other variables. Read More

Coalitions of the hindfoot are a relatively rare but challenging condition encountered by foot and ankle surgeons. Those that manifest between the cuboid and navicular (cubonavicular coalitions) are seen even more infrequently and are estimated to comprise ∼1% of all tarsal coalitions. Treatment for cubonavicular coalitions parallels protocols for more common hindfoot coalitions. Read More

Formation of the skeletal elements of the foot involves different stages of development. Failure in segmentation of the cartilaginous plate is supposed to be the underlying mechanism leading to tarsal coalition.

Tarsal coalitions have been reported in the setting of equinovarus foot deformities, but only as rare isolated findings. Failure to recognize this diagnosis may inhibit successful equinovarus correction. Here, we review a series of tarsal coalitions seen in congenital and neuropathic equinovarus deformity at two institutions, to report the breakdown of types of coalitions encountered, and to suggest methodology to facilitate earlier diagnosis.

Purpose: We aimed to determine the factors that influence the symptoms of naviculo-cuneiform (NC) coalition using radiography and computed tomography (CT).

Methods: We retrospectively reviewed the radiographic and CT findings of 37 NC coalition cases. The existence of a large pit (depth >3 mm), irregular articular surface, joint space narrowing, dorsal bony spur, subchondral sclerosis, multiple subchondral bony cysts, and intra-articular loose body were evaluated on radiographs or CT.

Lateral hindfoot pain associated with stage 2 to 3 adult-acquired flatfoot is often attributed to subfibular impingement. Preoperative magnetic resonance imaging (MRI) is generally performed to assess the extent of degeneration within the posterior tibial tendon, attenuation of medial soft tissue constraints, and degeneration of hindfoot and/or ankle articulations. The purpose of this study is to determine the incidence of lateral collateral ligament disease/injury associated with stages 2 and 3 adult-acquired flatfoot. Read More

Introduction: Recent studies suggest that hindfoot deformity should be considered in the surgical treatment of tarsal coalitions. Many authors have used the angle between the talus and the calcaneus (TCA) for decision-making. However, its reliability has not been demonstrated and the measurement technique has not been standardized. Read More

Tarsal coalition refers to an abnormal fibrous, cartilaginous, or bony connection that develops between two or more tarsal bones. Talocalcaneal coalition and calcaneonavicular coalition account for more than 90% of all cases of tarsal coalition. Coalition exists early at birth, but bony connection usually develops during the patient's late growth period. Read More

Spastic peroneal flatfoot (SPFF) is a rare hindfoot pathology usually seen in the adolescent age group that is characterized by painful spasms in the peroneal muscles. We have clinically observed that patients with SPFF also have some behavioral and emotional difficulties and problems in their academic achievements. Because of these observations, we investigated the prevalence and patterns of psychiatric disorders and intellectual disability among young subjects with SPFF. Read More

Background: The purpose of this study was to describe the technique of endoscopic resection of talocalcaneal coalition (TCC) by using 2 posterior portals and to report the outcomes of endoscopic resection of different types and sites of TCC.

Methods: An interventional prospective study was conducted on 20 feet in 18 consecutive patients who were diagnosed by computed tomography to have TCC for which nonoperative treatment had failed and endoscopic resection was performed. The patients were divided into groups according to the site of the coalition (middle facet or posterior facet) and according to type (fibrous, cartilage, or bony). Read More

Tarsal coalition is due to failure of segmentation between two or more foot bones during embryological development at a site where the joint cleft fails to develop. Depending on the nature of the tissue connecting the bones, the abnormality is a syndesmosis, synchondrosis, or synostosis. Although the coalition exists at birth, synostosis usually develops only late during growth. Read More

The ball-and-socket ankle joint is a rare deformity characterized by the loss of concavity in the trochlear surface of the talus with rounding of the articular surfaces of the distal fibula and tibia. Frequently, tarsal coalitions, fibular hypoplasia, and shortening of the limb accompany this deformity. To date, no data have been reported on surgical treatment of lateral ankle joint instability and peroneal tendon dislocation concomitant with a ball-and-socket ankle joint. Read More

It has been proposed that patients with talocalcaneal and talonavicular coalitions have decreased ankle joint range of motion. It has also been reported that rotational forces regularly absorbed by the talocalcaneal joint are transferred to the ankle joint in patients with coalitions, increasing the stress on the ankle joint after trauma. To the best of our knowledge, only 1 reported study has detailed the increased stress placed on the ankle joint secondary to a coalition. Read More

In 1975, Evans published an article describing the surgical management of the "calcaneo-valgus deformity," pointing out that the deformity was due to relative shortening of the lateral column of the foot. Correction involved "equalizing" both columns by performing an osteotomy in the neck of the calcaneus 1.5 cm from the calcaneocuboid joint, where a trapezoidal wedge of tricortical bone was placed.

Background: Calcaneonavicular coalitions are the most common form of tarsal coalitions. The prefered treatment for symptomatic coalitions is surgical resection; however, there are no published studies that directly compare different interposition techniques.
