Lateral Column Lengthening for Revision Triple and Double Arthrodesis and Severe End-Stage Flatfoot Deformity.

J Foot Ankle Surg 2019 Feb 8. Epub 2019 Feb 8.

Attending Physician, Kaiser Permanente San Leandro, San Leandro, CA.

Few options exist for the treatment of revision and severe cases of end-stage flatfoot deformity. Triple arthrodesis or medial-approach double arthrodesis have been the standard but often do not provide enough correction of the deformity. Lateral column lengthening is a powerful procedure performed either with an Evans calcaneal osteotomy or calcaneocuboid distraction arthrodesis that can be used as an adjunct in realigning the flatfoot.

Repair of the Deltoid Ligament Using Posterior Tibial Tendon Autograft:A Novel Technique.

J Foot Ankle Surg 2019 Jan;58(1):165-170

Faculty, Division of Foot & Ankle Surgery, West Penn Hospital, Allegheny Health Network, Pittsburgh, PA. Electronic address:

Posterior tibial tendon dysfunction (PTTD) is a progressive disorder secondary to advanced degeneration of the posterior tibial tendon, leading to the abduction of the forefoot, valgus rotation of the hindfoot, and collapse of the medial longitudinal arch. Eventually, the disease becomes so advanced that it begins to affect the deltoid ligament over time. This attenuation and eventual tear of the deltoid ligament leads to valgus deformity of the ankle.

Universidade de São Paulo, Faculdade de Medicina de Ribeirão Preto, Departamento de Biomecânica, Medicina e Reabilitação do Aparelho Locomotor, Ribeirão Preto, SP, Brasil.

Flexible flatfoot is a common condition in small children, which shows a strong tendency to spontaneously correct with their growth or to become moderate or mild in adults, which will not cause future problems. However, in a small number of cases, this condition is more severe, does not improve spontaneously, which may cause mechanical impairment, deformity, and, eventually, pain. In such cases, surgical treatment should be considered. Read More

Michigan International Foot and Ankle Center, St. Joseph Mercy Hospital - Oakland, Pontiac, Michigan; Departments of Orthopaedic Surgery, Wayne State University, Detroit, Michigan, and Michigan State University College of Osteopathic Medicine, East Lansing, Michigan; e-mail:

There has been debate recently as to whether the lateral column is actually short in the acquired flatfoot. Doubters argue that it is not possible for the lateral column to change in length and actually shorten, especially in the acquired type. In this series of 21 consecutive patients operated on for an acquired flatfoot, the calcaneocuboid joint (CC) had remodeled in all, resulting in the calcaneal side being short, facing laterally and dorsally.

Spring Ligament Instability.

Foot Ankle Clin 2018 Dec 22;23(4):659-678. Epub 2018 Sep 22.

Department of Orthopedic Surgery, Universidad de Chile, 1027 Independencia, Santiago 8380453, Chile; Department of Orthopedic Surgery, Hospital Clinico Universidad de Chile, Santos Dumont 999, Independencia, Santiago 8380456, Chile; Clinica Universidad de los Andes, Plaza 2501, Santiago 7620157, Chile.

The crucial role of the spring ligament complex within the pathologic process that leads to flatfoot deformity has evolved recently. There has been improvement in the anatomic knowledge of the spring ligament and understanding of its complex relationship to the deltoid complex and outstanding advances in biomechanics concepts related to the spring ligament. Optimization of flatfoot treatment strategies are focused on a renewed interest in the spring ligament and medial soft tissue reconstruction in concert with bony correction to obtain an adequate reduction of the talonavicular deformity and restoration of the medial longitudinal arch.

The "horseman" procedure is a surgical technique used to correct the talocalcaneal joint displacement of severe idiopathic flatfoot in children while maintaining the reduction with a temporary talocalcaneal screw. While this technique has been used since the early 1960s, very little has been reported on its results. Our objectives were to estimate the correction, functional results, and postoperative complications of the "horseman" procedure. Read More

First ray mobility and posterior tibial tendon dysfunction (PTTD) in persons with flatfoot: A case control study.

Foot (Edinb) 2018 Dec 3;37:57-60. Epub 2018 Aug 3.

Physical Education and Sports Science Academic Group, National Institute of Education, Nanyang Technological University, 1 Nanyang Walk, 637616, Singapore. Electronic address:

Background: While posterior tibial tendon dysfunction (PTTD) commonly presents with flat feet and has been thought to be associated with first ray mobility, many flat-footed individuals are asymptomatic and do not experience any symptoms of PTTD. Thus, there is a need to control for foot type when studying factors related to PTTD. This study aimed to clarify if first ray mobility differed between flat-footed individuals with and without symptoms of PTTD. Read More

Combined Subtalar and Naviculocuneiform Fusion for Treating Adult Acquired Flatfoot Deformity With Medial Arch Collapse at the Level of the Naviculocuneiform Joint.

Foot Ankle Int 2019 Jan 13;40(1):42-47. Epub 2018 Oct 13.

1 Kantonsspital Baselland, Liestal, Switzerland.

Background:: A challenge in treating acquired flatfoot deformities is the collapse of the medial arch at the level of the naviculocuneiform (NC) joint. Triple fusions, being a treatment option, may lead to problems such as increased foot stiffness. We thus established a method that combines subtalar (ST) fusion with NC fusion while preserving the Chopart joint. Read More

Bilateral Stress Fractures of the Talus Associated with Adult-Acquired Flatfoot Deformities.

Case Rep Orthop 2018 9;2018:5376384. Epub 2018 Sep 9.

Department of Rheumatology, JCHO Yugawara Hospital, 438 Miyakami, Yugawara, Ashigarashimo, Kanagawa 259-0396, Japan.

Adult-acquired flatfoot deformity is a progressive flattening of the arch of the foot that results from posterior tibial tendon insufficiency with a predilection for middle-aged women. A lateralized force vector associated with hindfoot valgus in adult-acquired flatfoot produces lateral ankle pain due to impingement at the lateral hindfoot, which can even lead to stress fractures of the distal fibula. Here, we present the rare case of a 73-year-old woman who presented with stress fractures of the bilateral taluses and unilateral distal fibula accompanied by severe adult-acquired flatfoot deformities.

Self-reported social and activity restrictions accompany local impairments in posterior tibial tendon dysfunction: a systematic review.

J Foot Ankle Res 2018 30;11:49. Epub 2018 Aug 30.

Department of Physiotherapy, School of Health and Rehabilitation Sciences, University of Queensland, Brisbane, Australia.

Background: Posterior tibial tendon dysfunction (PTTD) is a painful, progressive tendinopathy that reportedly predominates in middle-age, overweight women. There is no evidence based guidelines that clinicians can use to guide treatment planning, which leaves clinicians to make decisions on the basis of presenting clinical impairments and self-reported pain and disability. The purpose of this systematic review was to quantify clinical impairments, pain and disability in individuals with PTTD compared with controls. Read More

Acta Ortop Mex 2018 Mar-Apr;32(2):82-87

Ortopedia y Traumatología del Hospital General León. León, Gto., México.

The insufficiency of the posterior tibial tendon is the most common acquired cause of pain related to valgus flatfoot deformity in adults. The acquired flatfoot adult is a very painful symptomatic deformity resulting from a gradual stretching (attenuation) of the posterior tibial tendon and ligaments that support the arch of the foot. The progressive pain acquired flatfoot adult affects four times more women than men. Read More

Three-Dimensional Morphometric Modeling Measurements of the Calcaneus in Adults with Stage IIB Posterior Tibial Tendon Dysfunction: A Pilot Study.

Foot Ankle Spec 2018 Aug 31:1938640018796618. Epub 2018 Aug 31.

Department of Orthopaedic Surgery, Penn State Hershey Bone and Joint Institute (KCW, EPR, CMS, KLS, JLK, GSL, MCA) Penn State Milton S. Hershey Medical Center, Hershey, Pennsylvania.

Background: The pathophysiology of adult-acquired flatfoot deformity (AAFD) is not fully explained by degeneration of the posterior tibial tendon alone. While a shortened or dysplastic lateral column has been implicated in flatfoot deformity in pediatrics, there is no study that has quantified the degree of dysplasia in adults with a stage IIb flatfoot deformity, or if any exists at all.

Methods: An institutional radiology database was queried for patients with posterior tibial tendon dysfunction (PTTD) who had computed tomography (CT) performed. Read More

CARECI - University of Messina, Via C. del mare 41, 98121, Messina, Italy.

Objective: this study aims to develop a comprehensive 3D FE model of the foot to investigate the effect of soft tissue stiffness on the plantar pressure distributions and the internal load transfer between bony structures.

Methods: the stress shielding occurring on the plantar surface of a flatfoot was investigated and compared with the mechanical behavior of a healthy foot, trough baropodometric analyses and the FE models.

Results: the flatfoot evidences a more intensive stress-shielding map with significant values of pressure acting on the medial plantar fascia. Read More

Arthroereisis: What Have We Learned?

Foot Ankle Clin 2018 Sep 3;23(3):415-434. Epub 2018 Jul 3.

Foot and Ankle Department, Clinica Alemana, Universidad del Desarrollo, Avenida la Plaza 2501, Santiago 7620001, Chile.

One of the most common orthopedic problems in the authors' practice is flatfoot and, although it is most commonly treated conservatively, there is still lack of consensus about the type of surgical treatment that is best recommended in a specific patient. Keeping in mind that medial soft tissue reconstruction alone has not proved enough as an isolated procedure and that osteotomies and arthrodesis are considered more invasive surgery, arthroereisis is a quick, easy, and reproducible technique that seems to have good results without major complications in the correct patient. Indications, biomechanical principles, and technique are described in this article. Read More

Subtalar Joint Biomechanics: From Normal to Pathologic.

Foot Ankle Clin 2018 Sep 3;23(3):341-352. Epub 2018 Jul 3.

Department of Orthopaedics and Sports Medicine, University of Washington, Seattle, WA, USA.

Subtalar joint biomechanics are primarily driven by the shape of the articulations with contributions from the surrounding soft tissues. The joint motion occurs about a single axis oriented medially and superiorly. Joint contact forces change during different stages of gait and are affected by hindfoot alignment and traumatic alterations to their normal anatomy. Read More
