Objective: In double and triple major adolescent idiopathic scoliosis curves it is still controversial whether the lowest instrumented vertebra (LIV) should be L3 or L4. Too short a fusion can impede postoperative distal curve compensation and promote adding on (AON). Longer fusions lower the chance of compensation by alignment changes of the lumbosacral curve (LSC).

Hindfoot arthrodesis is often required for end-staged deformities, such as posterior tibial tendon dysfunction, osteoarthritis, or rheumatoid arthritis. Although the need for hindfoot arthrodesis is generally accepted in severe deformities, there is a debate whether a double or triple arthrodesis should be performed. The aim of our systematic review is to review the fusion rates and mean time to fusion in double and triple arthrodesis. Read More

Background: The role of arthrodesis as a salvage procedure in Diabetic Charcot Neuroarthropathic deformities of the Foot and Ankle is controversial due to relatively high complication rates reported in literature. We intend to present our experience with a retrospective analysis of Ankle and Hindfoot arthrodesis in deformities due to Diabetic Charcot Neuroarthropathy.

Study Design: A retrospective observational analysis of selected Diabetic Neuropathic Ankle and Hindfoot cases operated at a single centre. Read More

The approach to treatment of severe untreated or recurrent congenital talipes equinovarus deformities is very different in the world where patients are mobile, have access to repeated return visits for follow-up treatment, and where more sophisticated options for gradual correction with external fixation are available. For treatment, talectomy may be the only option to treat certain neglected clubfoot deformities during humanitarian programs and it may still have to be used as a salvage procedure used in modern foot surgery. Our extensive experience with these deformities has been on global humanitarian programs. Read More

Background And Objective: Mid/hindfoot arthrodesis could modify the misalignment of adult-acquired flatfoot and attenuate pain. However, the long-term biomechanical effects of these surgical procedures remain unclear, and the quantitative evidence is scarce. Therefore, we aimed to investigate and quantify the influences of five mid/hindfoot arthrodeses on the internal foot biomechanics during walking stance. Read More

Arthrodesis of the hindfoot is typically used for the correction of severe and arthritic progressive collapsing foot deformity. Concomitant bony or soft tissue procedures may be helpful in patients with congenital abnormalities including the ball-and-socket ankle or congenital vertical talus. Dysplasia of the hindfoot bones may be more common than previously recognized, and corrective procedures or alterations in technique may need to be performed during hindfoot arthrodesis to account for bony deformity.

Objectives: The purpose of this study was to examine the biomechanical effects of fixation on range of motion (ROM) in the upper and lower adjacent segments of different lumbar spine segments in a goat spine model.

Methods: Fifteen goat spine specimens (vertebrae T12-S1) were randomly divided into three groups: A (single-segment fixation), B (double-segment fixation), and C (triple-segment fixation). Motion in different directions was tested using a spinal motion simulation test system with five external loading forces. Read More

Purpose: Idiopathic clubfoot affects approximately 1/1000 alive-born infants, of whom 80-91% are born in low- or middle-income countries (LMICs). This retrospective study aimed to evaluate the morphological, functional, and social outcomes in patients with neglected clubfoot in rural Bangladesh, after receiving surgical treatment.

Methods: Patients received a posteromedial release (PMR) with or without an additional soft tissue intervention (group 1), a PMR with an additional bony intervention (group 2), or a triple arthrodesis (group 3) according to our surgical algorithm. Read More

Introduction: Flexible flatfoot refers to the loss of the medial longitudinal arch of the foot on weight bearing and is associated with excessive heel eversion or forefoot abduction. Unless symptomatic, flexible flatfeet are best managed non-operatively. The calcaneo-cuboid-cuneiform osteotomy is a procedure that restores the anatomical shape of the foot without arthrodesis of the joints. Read More

Cavus foot is a complex podiatric deformity that requires precise and in-depth work-up through an objective, physical, and radiographic examination. The goal of surgical treatment is to eliminate pain while establishing a plantigrade foot structure. Triple arthrodesis has proven to be an effective surgical procedure for treatment of moderate to severe rearfoot deformity with or without the presence of rearfoot arthritic changes. Read More

Background: No studies to date have elucidated the clinical factors associated with pedicle screw pull-out during or immediately after surgery. The aim of this study was to assess the frequency of pedicle screw pull-out by comparing intraoperative scans obtained using cone-beam computed tomography (CBCT) with postoperative scans obtained using computed tomography (CT). We also sought to determine the incidence of pedicle screw pull-out and identify relevant risk factors. Read More

Background: Müller-Weiss disease (MWD) is an idiopathic foot condition characterized by spontaneous tarsal "scaphoiditis" in adults. Frequently bilateral and affecting females during the 4-6 decades of life, the pathogenesis of MWD remains unclear: It has been traditionally considered a spontaneous osteonecrosis of the navicular. The typical presentation of MWD is a long period of subtle discomfort followed by prolonged standing, atraumatic, disabling pain. Read More

Flatfoot is a common deformity in the pediatric population and has a multitude of causes. Sometimes, it can be a normal finding in children, and treatment should not be guided only based on the appearance, but rather after thoroughly assessing the patient and the impact it has on the child's daily life. In this paper, we describe the quality of life that the patients are experiencing after the surgical treatment of this pathology. Read More

Case: Complete extrusion of the talus is rare and associated with high rates of complications including infection, osteonecrosis, persistent pain and stiffness, and post-traumatic arthritis. Less well described is associated midfoot instability. We report a case of a complete extruded missing talus that resulted in significant midfoot instability treated with a modified triple arthrodesis of the tibiocalcaneal, tibionavicular, and calcaneocuboid joints.

Middle facet tarsal coalition is one of the commonly seen tarsal coalitions in clinical practice that can cause pain and associated flatfoot deformity. Excision of the coalition is one of the treatment options for symptomatic cases. Although symptoms may subside in children following a period of immobilization, resection should be considered as a treatment alternative for children and adolescents because of the potential for restoration of subtalar joint movement.
