What Is the Treatment "Algorithm" for Infection After Ankle or Hindfoot Arthrodesis?

There is no universal algorithm for addressing the infected ankle or subtalar arthrodesis. A potential algorithm created by consensus is.

Outcomes of Total Ankle Replacement, Arthroscopic Ankle Arthrodesis, and Open Ankle Arthrodesis for Isolated Non-Deformed End-Stage Ankle Arthritis.

End-stage ankle arthritis is a disabling condition that has a similar effect on morbidity, pain, and loss of function to hip arthritis. We compared clinical outcomes of total ankle replacement (TAR) involving the HINTEGRA prosthesis (Integra LifeSciences), arthroscopic ankle arthrodesis (AAA), and open ankle arthrodesis (OAA) in patients with isolated, non-deformed end-stage ankle arthritis.

Considerations in the Surgical Management of End-Stage Ankle Arthritis: Commentary on an article by Andrea N. Veljkovic, BComm, MPH, MD, FRCSC, et al.: "Outcomes of Total Ankle Replacement, Arthroscopic Ankle Arthrodesis, and Open Ankle Arthrodesis for Isolated Non-Deformed End-Stage Ankle Arthritis".

Development of a Small Animal Ankle Arthrodesis Model.

Our understanding of the biology of ankle arthrodesis is based largely on work in spine and long bone animal models. However, the local soft tissue and vascular anatomy of the foot and ankle is different from that of the spine. Accordingly, the objective of this study was to develop a small animal ankle arthrodesis model.

Erratum: Subtalar Arthrodesis with Use of Adipose-Derived Cellular Bone Matrix Compared with Autologous Bone Graft.

The influence of selective arthrodesis on three-dimensional range of motion of hindfoot joint: A cadaveric study.

The purpose of this study was to measure the three-dimensional range of motion of adjacent, unfused joint or joints after different arthrodesis of hindfoot.

The horizontal calcaneofibular ligament: a sign of hindfoot valgus on ankle MRI.

Hindfoot valgus malalignment has been assessed on coronal MRI by the measurement of the tibio-calcaneal (TC) angle and apparent moment arm (AMA). This study aimed to determine if the calcaneofibular ligament (CFL) angle could be used as a further marker of hindfoot valgus malalignment on routine non-weight-bearing ankle MRI.

Hindfoot-centred X-ray technique for the evaluation of cavovarus deformity : A proposal for the optimization of radiologic delineation.

In surgical correction of cavovarus deformity bony hindfoot procedures are required in most cases. For treatment planning X‑rays in two or more planes are usually used. In conventional X‑ray-techniques the hindfoot and ankle joint are presented in a more or less outward rotated position. Moreover, the peritalar complex is not delineated in the most corrected position. Therefore, the frequently used talus-metatarsal-I-angle (Meary angle) cannot be measured correctly. By application of the Coleman block t...

Small joint arthrodesis technique using a dowel bone graft in a rabbit model.

The dowel bone graft fusion technique for the ankle is a well-known and useful method. However, clinical results of dowel bone graft for small joint fusion are unknown. The objective of the present study is to evaluate the effects of dowel bone graft technique for small joint arthrodesis in an in vivo arthrodesis of rabbit elbow model compared with the conventional arthrodesis technique (open, joint surface debridement, and internal fixation method). We assigned 28 young adult New Zealand white rabbits to o...

Letter regarding "Clinical outcomes comparing arthroscopic vs open ankle arthrodesis".

Post-Traumatic Hindfoot Arthritis.

The hindfoot is functionally defined as the articulations between the talus, calcaneus, navicular, and cuboid. It is a biomechanically important peritalar unit for shock absorption and propulsion with the subtalar and talonavicular joint essential to its function. The primary cause of hindfoot arthritis is post-traumatic. Other causes include long-term misalignment such as adult-acquired flatfoot, cavus foot, and inflammatory arthritis. Prevention of post-traumatic hindfoot arthritis is the primary objectiv...

Proximal interphalangeal joint arthrodesis using a compression wire: A comparative biomechanical study.

Arthrodesis of the proximal interphalangeal joint is a proven technique for treating of a range of pathological conditions, including osteoarthritis. There are multiple surgical procedures. A biomechanical study was conducted to compare the stability of a compression wire to intraosseous wiring for the arthrodesis. Seventeen formalin-fixed human fingers were randomly assigned into two groups and the bone mineral density was determined. Arthrodesis in 20° flexion was performed using an oblique compression w...

Complications and results of the arthrodesis after total ankle arthroplasty failure: a retrospective monocentric study of 12 cases.

Total ankle arthroplasty (TAA) has the objective to maintain the range of motion of the tibiotarsal joint and to preserve the nearby joints. However, the complication rate and failures remain quite high after TAA. The main objective of the study was to evaluate the improvement in the functional scores of the tibiotarsal arthrodesis after TAA failure. The secondary objective was to assess the specific complications.

In Vitro Evaluation of a Novel Osteo-Inductive Scaffold for Osteogenic Differentiation of Bone-Marrow Mesenchymal Stem Cells.

Demineralized bone matrices (DBMs) were demonstrated to be a promising candidate for bone regeneration by previous studies. However, the limited osteoinductivity of DBMs was insufficient for a better repairing of bone defect. Osteoblasts (OBs), the major cellular component of bone tissues, play an important role in the formation of new bone. The extracellular matrix (ECM) of OB is one of the main components of bone formation niche.

Is Lower-limb Alignment Associated with Hindfoot Deformity in the Coronal Plane? A Weightbearing CT Analysis.

The goals of lower limb reconstruction are to restore alignment, to improve function, and to reduce pain. However, it remains unclear whether alignment of the lower limb and hindfoot are associated because an accurate assessment of hindfoot deformities has been limited by superposition on plain radiography. Consequently, surgeons often overlook hindfoot deformity when planning orthopaedic procedures of the lower limb. Therefore, we used weight-bearing CT to quantify hindfoot deformity related to lower limb ...

Cellular Processes by Which Osteoblasts and Osteocytes Control Bone Mineral Deposition and Maturation Revealed by Stage-Specific EphrinB2 Knockdown.

We outline the diverse processes contributing to bone mineralization and bone matrix maturation by describing two mouse models with bone strength defects caused by restricted deletion of the receptor tyrosine kinase ligand EphrinB2.

The Anterolateral Thigh-Medial Femoral Condyle Chimeric Flow-through Flap for Posttraumatic Wrist Arthrodesis.

Wrist arthrodesis in the setting of segmental bone loss can have high failure rates. Therefore, vascularized bone grafting has been advocated for select patients. Patients suffering concomitant large soft tissue loss present even greater challenge. To that end, we describe for the first time successful anterolateral thigh-medial femoral condyle chimeric flow-through flap for posttraumatic wrist arthrodesis and soft tissue coverage. This is a case report of a 19-year-old male laborer who suffered a large bla...

What Is the Optimal Management of Patients With Prior Septic Arthritis of the Ankle Who Are Undergoing Total Ankle Arthroplasty (TAA)?

There is a paucity of data regarding total ankle arthroplasty (TAA) in patients with prior infection involving the ankle, whether it be septic arthritis, osteomyelitis, or infection of the surrounding soft tissues. We recommend that patients with prior infections in the affected ankle be worked up for infection, including a thorough history and physical examination, as well as ordering serologic tests and possible aspiration of the joint. During ankle arthroplasty in patients with prior infection, antibioti...

Functional Outcomes and Complications Following Scapulothoracic Arthrodesis in Patients with Facioscapulohumeral Dystrophy.

Facioscapulohumeral dystrophy (FSHD) is an autosomal-dominant myopathy characterized by facial and shoulder girdle muscle weakness with scapular winging. Scapulothoracic arthrodesis is a successful treatment approach for patients with

Radiotherapy for osteoarthritis of the ankle and tarsal joints-analysis of 66 joints.

Osteoarthritis of the ankle and tarsal joints is less common than osteoarthritis of the knee or hip, but the associated disability is at least as severe as that of the other major joints of the lower limb. The results for total arthroplasty are still not satisfactory. For this reason, arthrodesis is still the gold standard of non-joint-conserving surgery. For the reason of functionality, joint-conserving therapies play a major role in treatment of ankle and tarsal osteoarthritis. Low-dose radiotherapy has ...

First Metatarsophalangeal Joint Arthrodesis Using an Intraosseous Post and Lag Screw With Immediate Bearing of Weight.

Arthrodesis is the gold standard procedure for advanced arthrosis of the first metatarsophalangeal joint. Having a strong construct is preferable for allowing immediate bearing of weight, which facilitates patient rehabilitation. Plate and screw fixation is currently in favor but can lead to prominent metalware necessitating removal. The aim of this study is to report the results of a series of 54 first metatarsophalangeal joint arthrodeses performed in 52 patients treated with an implant composed of an int...

Evaluation of a bioengineered ACL matrix's osteointegration with BMP-2 supplementation.

A poly (l-lactic) acid bioengineered anterior cruciate ligament (ACL) matrix has previously demonstrated the ability to support tissue regeneration in a rabbit ACL reconstruction model. The matrix was designed for optimal bone and ligament regeneration by developing a matrix with differential pore sizes in its bone and ligament compartments. Building upon past success, we designed a new bioengineered ACL matrix that is easier to install and can be used with endobutton fixation during ACL reconstruction. To ...

Proximally Based Split Abductor Hallucis Turnover Flap for Medial Hindfoot Reconstruction: A Case Report.

Limited reconstructive options exist for soft tissue defects of the foot and ankle because of a lack of surrounding tissue. Although microsurgical free flaps have become a popular treatment modality for this anatomic region, pedicled muscle flaps can provide robust coverage of small foot wounds with significantly less donor site comorbidity. One such muscle is the abductor hallucis, which can be used as a proximally based turnover flap to cover medial hindfoot defects. However, complete distal disinsertion ...

Arthrodesis of the Infected Knee Joint with the Ilizarov External Fixator: an Analysis of 13 Cases.

Knee joint infections with pronounced joint destruction, soft tissue and bone involvement are serious diseases in which not only the joint but also the entire extremity are directly endangered. What results can be achieved with the Ilizarov external fixator for septic knee arthrodesis?

Osteocyte-Mediated Translation of Mechanical Stimuli to Cellular Signaling and Its Role in Bone and Non-bone-Related Clinical Complications.

Osteocytes comprise > 95% of the cellular component in bone tissue and produce a wide range of cytokines and cellular signaling molecules in response to mechanical stimuli. In this review, we aimed to summarize the molecular mechanisms involved in the osteocyte-mediated translation of mechanical stimuli to cellular signaling, and discuss their role in skeletal (bone) diseases and extra-skeletal (non-bone) clinical complications.
