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

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

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

Tarsal coalitions represent a cohort of conditions characterized by bony, cartilaginous, or fibrous union of two or more tarsal bones. These disorders are often poorly understood by medical professionals, often leading to delays in diagnosis and treatment. They may be asymptomatic or cause hindfoot pain, stiffness, decreased range of motion, and foot deformities. Read More

In recent years, some authors have reported accessory anterolateral talar facet impingement with flatfoot including peroneal spastic flatfoot. Conversely, to our knowledge, no case report has been published about accessory anterolateral talar facet impingement with tibialis spastic varus foot.

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. The purpose of the present study was to retrospectively compare pain relief, functional outcomes, and complications of children and adolescents who had a resection of a symptomatic calcaneonavicular coalition with interposition of fat graft, bone wax, or extensor digitorum brevis (EDB).

Posteromedial subtalar (PMST) coalitions are a recently described anatomic subtype of tarsal coalitions. We compared with clinical patient-based outcomes of patients with PMST and standard middle facet (MF) coalitions who had undergone surgical excision of their coalition. The included patients had undergone surgical excision of a subtalar tarsal coalition, preoperative computed tomography (CT), and patient-based outcomes measures after surgery (including the American Orthopaedic Foot and Ankle Society [AOFAS] scale and University of California, Los Angeles [UCLA], activity score).

Rarely, osteochondral lesions of the talus occur without a history of trauma. Accurate interpretation of the mechanical load distributions onto the ankle leading to potential atraumatic cartilage damage must always be studied. The published data on the optimal treatment of talar osteochondral lesions in skeletally immature patients are scarce, especially when the lesions are associated with hindfoot malalignment.

There has been a lot of hype surrounding the advantages to be gained from rapid prototyping processes in a number of fields, including medicine. Our literature review aims objectively to assess how effective patient-specific surgical guides manufactured using rapid prototyping are in a number of orthopaedic surgical applications. To this end, we carried out a systematic review to identify and analyse clinical and experimental literature studies in which rapid prototyping patient-specific surgical guides are used, focusing especially on those that entail quantifiable outcomes and, at the same time, providing details on the guides' design and type of manufacturing process.

Tarsal coalition (a congenital fibrous, cartilaginous, or bony connection between two bones) classically presents with recurrent ankle sprains or with insidious onset of a painful, stiff flatfoot. Flatfoot is a benign finding most of the time, but it is important to distinguish the rigid flatfoot from the flexible flatfoot. A patient with recurrent sprains of the ankle or a stiff flatfoot should be evaluated for a tarsal coalition. Read More

Tarsal coalitions are an abnormal union between 2 tarsal bones.

Others have suggested that the ray deficiency is in the central portion of the midfoot and forefoot.We sought to determine whether cuboid preservation and/or cuneiform deficiency in the feet of patients with congenital fibular deficiency implied that the ray deficiency is central rather than lateral in patients with congenital fibular deficiency.
