Outcomes of triple arthrodesis with IOFIX type fixation: A prospective study.

Background: The aim of this study was to evaluate the patient reported outcome measures (PROMS), radiological outcome and complications when performing a triple arthrodesis using the IOFIX system for the talonavicular and calcaneocuboid joints.

Methods: Data was collected prospectively. Twenty-nine consecutive patients were reviewed 1 year postoperative.

A Case of Complex Deformity of Knee Corrected by Ilizarov Fixation in a Teenage Patient.

Introduction: After the spine, the knee is the second most common location for skeletal tuberculosis. An unusual complication of tuberculosis infection is triple knee deformity. The combination of knee flexion, posterolateral tibial subluxation, and external tibial rotation over femoral condyles manifests as a severe deformity.

Avascular necrosis of the navicular (Müller-Weiss). A systematic review.

Müller-Weiss is a disease characterized by deformation, fragmentation and necrosis of the navicular, which presents with midfoot varus and long-standing pain, mostly in females. It is related to delayed ossification due to physical or nutritional stress, associated with abnormal force distribution. There are still few studies on this condition and there is no consensus in the literature on its classification and treatment.

First Tarsometatarsal Alignment May Self-Correct After Triple Arthrodesis in Progressive Collapsing Foot Deformity.

Background: Triple arthrodesis is commonly used to correct rigid progressive collapsing foot deformity (PCFD). These patients often have associated first tarsometatarsal (TMT) instability on lateral weightbearing radiographs. It has not been well established if it is necessary to add first TMT arthrodesis to adequately correct the overall deformity.

Patient-specific modelling of contact characteristics in the ankle joint following triple arthrodesis in valgus, neutral and varus hindfoot positions.

The aim of the current study was to understand the importance of the joint alignment following triple arthrodesis by analysing the contact characteristics in a normal and arthritic ankle joint using a patient-specific numerical model developed using open source software. The alignment of the hindfoot with respect to tibia is calculated from CT scans and the ankle joint model was numerically analysed for neutral, valgus and varus positions in both normal and arthritic conditions. The contact area, the magnitude and distribution of the contact pressure on the articular surface of the talar dome was evaluated using a cell-centred Finite Volume Method implemented in open-source software OpenFOAM.

Lambrinudi Triple Arthrodesis with Posterior Tibial Tendon Transfer in Adult Fixed Equinus Deformity: Case Report.

Introduction: Fixed Equinus deformity is characterized by limited dorsiflexion of ankle joint and restricted passive movement, along with medial and lateral tibiotalar instability, progressive hindfoot varus, and a supination deformity of the forefoot. Degree of equinus deformity is determined by the Tibio-Metatarsal (TM) angle, subtended between the longitudinal axes of Tibia and 1st Metatarsal, in lateral view of foot. Lambrinudi triple arthrodesis involves the surgical fusion of the talonavicular, talocalcaneal, and calcaneocuboid joints to correct fixed foot deformities, to relieve pain from joint, to provide stability to the imbalanced foot, and to create a plantigrade foot.

Association of Timing of Hindfoot Arthrodesis and Early Reoperation Rates for Total Ankle Arthroplasty.

Background: Prior literature has demonstrated that ipsilateral hindfoot arthrodesis may increase the risk for reoperation after total ankle arthroplasty (TAA) and that simultaneous hindfoot arthrodesis with TAA could result in short-term clinical and radiologic improvements. The purpose of this study is to compare the reoperation rates after TAA with prior hindfoot arthrodesis vs simultaneous arthrodesis and TAA.

Methods: Patients who underwent primary TAA were identified in the PearlDiver database.

Operative Time, Cost, and Union Rate of Power Rasp Joint Preparation Versus Traditional Preparation in Arthrodesis of the Foot and Rearfoot.

Time spent in the operating room is valuable to both surgeons and patients. One of the biggest rate-limiting factors when it comes to arthrodesis procedures of the foot and ankle is cartilage removal and joint preparation. Power instrumentation in joint preparation provides an avenue to decrease joint preparation time, thus decreasing operating room time and costs.

Isolated Subtalar Repositional Arthrodesis Compared With Triple Arthrodesis for the Treatment of Progressive Collapsing Foot Deformity.

The optimal extent of arthrodesis for severe and rigid progressive collapsing foot deformity is controversial. Traditionally, triple arthrodesis has been recommended; however, good results have been reported using subtalar arthrodesis only. We compared the results of triple arthrodesis and isolated subtalar repositional arthrodesis.

Retrospective Review of Complications and Revision Rates Between Isolated Talonavicular vs Talonavicular and Subtalar (Double) Arthrodesis vs Triple Arthrodesis.

Background: Hindfoot fusion procedures are common for the treatment of end-stage arthritis or deformity. Surgical treatments for these conditions include talonavicular joint (single) arthrodesis, talonavicular and subtalar (double) arthrodesis, or talonavicular, subtalar, and calcaneocuboid (triple) arthrodesis. This study evaluated the complication rate, revision surgery rate, and hardware removal rate for those treated with either single, double, or triple arthrodesis.

Normal and malaligned talonavicular fusion alters cadaveric foot pressure and kinematics.

Talonavicular (TN) fusion is a common treatment for TN arthritis or deformity correction. There is incongruous evidence regarding remaining motion at the talocalcaneal and calcaneocuboid joints after TN fusion. Additionally, the effects of a malaligned TN fusion are not well understood and alignment of the fusion may be important for overall foot integrity.

Comparison of preemptive and preventive intravenous acetaminophen on opioid consumption in pediatrics undergoing posterior spinal fusion surgery: a randomized controlled trial.

Background: Posterior spinal fusion (PSF), commonly used for adolescent idiopathic scoliosis (AIS), causes severe postoperative pain. Intravenous (IV) administration of acetaminophen has shown promise for opioid-sparing analgesia; however, its analgesic effect and optimal timing for its standard use remain unclear. Our study aimed to evaluate the analgesic effect and optimal timing of IV acetaminophen administration in pediatric and adolescent patients undergoing PSF and requiring adequate pain control.

The effect of early weight-bearing on bone fusion after triple arthrodesis.

Triple arthrodesis is an effective method for treating stiff horseshoe feet and severe osteoarthritis. However, it is still a challenge to improve postoperative bone fusion by changing early weight-bearing. This study improved the classical bone remodeling algorithm, established a mathematical relationship between density change rate and mechanical stimulation, and combined it with finite element theory.

[Scapulothoracic dissociation as a consequence of failure of traditional treatment in an adolescent girl: a case report].

Scapulothoracic dissociation due to a trauma is exceptional. The purpose of this study was to share our experience with a case of scapulothoracic dissociation and to explain the advantages of our approach. We report the case of a 12-year-old right-handed schoolgirl admitted to hospital with a blunt trauma to the right thoracic limb complicated by infection after a week of traditional treatment (massage, bandaging with reed splints).

The Nightmare of Calcaneus: Gustilo-Anderson Type IIIB Fractures.

Background: The aim of this study was to share the clinical results of open calcaneus fractures, which are extremely rare and have become the fearful nightmare of orthopedic surgeons.

Methods: Between June of 2014 and June of 2020, of 196 patients with the diagnosis of calcaneus fracture, Gustilo-Anderson type IIIB, 17 patients (11 men and six women; mean age, 36.2 ± 4.

Patient Reported Outcomes Following Triple Arthrodesis for Adult Acquired Flat Foot Deformity: Minimum Two Year Follow Up.

The aim of this study is to analyze patient-reported outcomes following this procedure as well as any demographics that may confer prognostic capability. A retrospective analysis was conducted of patients who underwent Triple Arthrodesis at our facility from 2014-2021. Patients were selected if they underwent an isolated triple arthrodesis.

K-Wire Osteosynthesis for Arthrodesis of the Paediatric Foot Is a Good and Valid Procedure.

Background: Foot deformities in children are common, and the majority can be treated conservatively. Nevertheless, there are deformities that require surgical treatment. These include rigid clubfeet, severe forms of pes planovalgus, pes cavus and several more.

Breaking the Rules in Three Dimensions: What to Expect After a Thoracic-only Fusion With Structural Thoracic and Thoracolumbar Curves.

Objective: Despite guidelines to fuse both thoracic and thoracolumbar/lumbar (TH/L) curves in patients with structural curves in both regions, a thoracic-only fusion allows preservation of lumbar motion segments. The purpose of this study was to assess the 2-year postoperative three-dimensional (3D) radiographic and clinical outcomes of patients with double or triple major (thoracic curves >TH/L curves) structural curves who underwent a thoracic-only fusion.

Methods: A prospective adolescent idiopathic scoliosis registry was queried for double or triple major curves undergoing thoracic-only posterior fusion and a minimum 2-year follow-up.

Outcomes of Selective Arthrodesis Based on Joints Affected in 33 Feet With Müller-Weiss Disease.

No consensus exists regarding operative treatment of Müller-Weiss disease (MWD). Its only classification is based solely on Méary's angle and serves neither as guide to management nor prognosis. We report on 33 feet that underwent surgery following failed conservative management.

Alteration of Lower Limb Kinematics and Kinetics due to Bilateral Triple Arthrodesis.

Objectives: The study aimed at discovering the existing differences in lower limb joints' kinematics, and EMG signals of 4 particular muscles of the ankle joint during gait, between normal subjects and patients with bilateral triple arthrodesis.

Methods: In this research, a 3D motion analysis system was used and joints' angles were calculated using a MATLAB code, and based on the data collected from markers movements, for patients with bilateral triple arthrodesis and normal subjects. Moreover, the EMG signals of ankle muscles in each subject, and the graphs of mean plus and minus standard deviation of lower limb joint angles and muscles' EMG were calculated by MATLAB.

Optimal Sequence of Corrective Surgeries for Concomitant Valgus Knee and Rigid Pes Planus Deformities: The Knee-First Approach.

In patients requiring surgical correction of ipsilateral valgus knee and rigid pes planovalgus deformities, the optimal operative sequence is controversial. Growing evidence suggests these 2 deformities are related in etiology and interrelated in disease course. We present the case of a 72-year-old female with concomitant valgus knee and rigid pes planovalgus deformities successfully treated with total knee arthroplasty followed by triple arthrodesis and Achilles lengthening.
