Association of calcaneal pitch angle with recurrence of postoperative hallux valgus in patients with rheumatoid arthritis.

Hallux valgus (HV) and flatfoot deformities are frequently seen in patients with rheumatoid arthritis (RA). This study aimed to determine whether flatfoot deformity contributes to the recurrence of HV in RA patients. This study examined 62 feet from 45 RA patients who were diagnosed with HV and underwent the first metatarsal joint-preserving surgery between November 2010 and October 2021.

Percutaneous calcaneal sliding osteotomy with the rising sun technique.

Background: Calcaneal slide osteotomies represent a well-established component in the surgical treatment of joint-preserving hind foot corrections. The percutaneous technique aims to minimize the surgical morbidity and maximize surgical efficiency. There is a consensus that percutaneous calcaneal sliding osteotomy (PCSO), using a low-speed and hightorque burr, is generally performed in four steps corresponding to the four quadrants of the cross-section of the calcaneal tuber.

Mueller-Weiss Syndrome, a Rare Cause of Flatfoot: Case Report.

Introduction: There are numerous causes of flatfoot, among them osteonecrosis of the navicular bone, a rare disease known as Mueller-Weiss syndrome, also leads to deformity.

Case Report: A 53-year-old male presented to our Outpatient Department with pain and swelling over bilateral foot for 3 years with increased severity in the left. Physical examination as well as footprint revealed a bilateral flat foot, and there was tenderness as well as swelling over the dorsomedial aspect of bilateral foot.

Development of an automated foot contact area measurement program for podoscopes using ChatGPT-4: a case report.

Accurate measurement of the foot contact area is crucial for diagnosing pes planus (flatfoot) and pes cavus (high arch), which significantly affect pressure distribution across the plantar surface. This study aimed to develop a program using ChatGPT-4 to automate foot contact area measurements using a podoscope, thereby enhancing diagnostic precision. A 53-year-old female volunteer stood on a podoscope to capture images of her feet, which were processed to isolate the foot contours and measure the contact areas.

Immediate effects of soft tissue mobilization and percussive massage on balance in young adults with pes planus: A single blind, randomized controlled pilot study.

Background: Presence of pes planus is known to effect balance. In this study, it was aimed to examine the immediate effects of IASTM and PMT on static and dynamic balance in young adults with pes planus.

Method: The navicular drop test was used to diagnose pes planus.

Nonunion and Calcaneocuboid Subluxation Are Minimal After Evans Osteotomy Without Fixation.

Background: Fixation of the Evans osteotomy for flatfoot correction has been advocated without supporting data to facilitate union and avoid calcaneocuboid subluxation. We examined these issues in the largest reported series of Evans procedures to date.

Methods: A total of 118 cases from a consecutive series of 137 patients who underwent Evans osteotomy without fixation by a single surgeon were available for review.

A single computational model to simulate the three foot-rocker mechanisms of the gait cycle.

The use of computational models of the human foot based on finite element analysis offers a promising alternative for understanding the biomechanical internal changes of this structure. However, the evaluation of dynamic scenarios has been challenging. This research aims to design a computational model that accurately simulates foot biomechanics during the stance period of the gait cycle in healthy and flatfoot scenarios.

Valgus deformity of the distal tibia in children and adolescents with idiopathic flatfoot: Can it be predicted using 3D movement analysis?

Background: Distal tibial valgus deformity, though common in various medical conditions, has not been extensively studied in idiopathic flatfoot. It clinically presents as hindfoot valgus, mimicking flatfoot deformity, and requires X-rays for detection. Severity is quantified using resting calcaneal angle and standing tibio-calcaneal angles (STCA), but their prognostic value for identifying distal tibial valgus deformity remains unclear.

Use of the Arthrex ProStop Subtalar Arthroeresis Screw in the Management of Symptomatic Paediatric Flexible Flatfoot.

Introduction:  Paediatric flexible flatfoot (PFFF) is a common, potentially debilitating condition affecting a significant proportion of active children. Despite its prevalence, there is a lack of consensus on optimal operative management in symptomatic children. We report a unique case series of six feet treated with the Arthrex ProStop Subtalar Arthroeresis Screw (Arthrex, UK) in the North West of England.

Tarsal coalition resection in children: Is it effective?

Tarsal coalitions in children are a group of disorders that typically present as a rigid flatfoot deformity. Operative treatment generally consists of resecting the coalition alone or resection plus flatfoot reconstructive procedures. The purpose of this study was to evaluate the rate and risk factors for complications, including infection, recurrence, and reoperation, following the surgical management of tarsal coalitions in children.

[Talonavicular arthrodesis].

Objective: Realignment of the hindfoot by talonavicular arthrodesis.

Indications: Idiopathic and posttraumatic arthritis of the talonavicular joint with or without malalignment. Optional in flatfoot reconstruction.

Comparative study of subtalar arthroereisis, medializing calcaneal osteotomy and the combination of both techniques for the treatment of symptomatic adult flatfeet.

Background: Symptomatic adult flatfeet are a common problem that is treated with various therapeutic approaches. In this study, three different surgical approaches, subtalar arthroereisis (SA), medializing calcaneal osteotomy (MDCO) and a combination of both techniques (SA+MDCO) were analyzed.

Methods: 32 patients (36 feet) with pes planovalgus (mean age 49 +/- 16 years) were surgically treated with either SA (n = 8 feet), MDCO (n = 9 feet) or SA+MDCO (n = 19 feet).

HyProCure for Flatfoot Deformity: A Clinical Characteristics Analysis in China.

Background: Flatfoot is a common foot disorder involving progressive foot deformity of the three-dimensional structures of the forefoot, midfoot, and hindfoot. Currently, Chinese surgeons and patients favor subtalar arthroereisis (SA) due to its minimally invasive and low-damage characteristics. HyProCure device is widely used.

Change in Plantar Pressure and Plain Radiography in Pediatric Flexible Flatfoot: A Retrospective Cohort Study.

Objective: To investigate longitudinal changes in plantar pressure examinations and plain radiographs and to assess the correlations between these two modalities in pediatric patients with flexible flatfoot (FFF).

Methods: Pediatric patients diagnosed with FFF were analyzed in this retrospective cohort study. Medical records were reviewed to collect data on plain radiographs and plantar pressure examinations.

Innovative surgical treatment of tarsal coalition in flatfoot: Resection and interposition of synthetic membrane, flexible bioresorbable polymers film, as adhesion barrier and subtalar arthroeresis. Up to nine years follow-up.

Tarsal coalition can be a long term severely disabling condition. For symptomatic cases with flatfoot surgical resection of coalition and subtalar arthroeresis represents the most common treatment. Literature reports variable outcomes and recurrence.

Tibialis Anterior Tendon Transfer for Clubfoot Deformity: Cuboid Versus Lateral Cuneiform.

Background: Tibialis anterior tendon transfer in relapsing clubfoot deformity is a well-known treatment option for dynamic forefoot supination and adduction deformities. The tibialis anterior tendon can be anchored to the lateral cuneiform or the cuboid. A complication of this surgery is overcorrection to a flatfoot deformity or undercorrection that maintains the clubfoot deformity.
