BACKGROUND: It is usually accepted that acquired flatfoot deformity after injury is usually due to partial or complete tear of the posterior tibial tendon (PTT), with secondary failure of the other structures which maintain the medial longitudinal arch, such as the plantar calcaneo-navicular (SPRING) ligament. It is unusual to find an isolated Spring Ligament (SL) tear, with an intact TP tendon. METHODS: The medial arch reconstruction technique of an isolated SL tear in 5 patients is presented discussed in this paper...

Abnormalities of the medial ligaments and posterior tibial tendon can occur because of acute injury or chronic instability or malalignment. Medial ankle injuries may occur because of pronation or supination-external rotation injuries. Deltoid ligament injuries have a significant impact on lateral ankle instability but can be overlooked in patients with lateral ligament injuries. Posterior tibial tendon dysfunction is usually associated with spring ligament or flexor retinaculum injury. Tarsal tunnel syndrome, accessory flexor muscles, and subtalar coalition should be considered as well as ligament and tendon tears in differential diagnosis of chronic medial ankle pain...

BACKGROUND: Posterior tibial tendon (PTT) is particularly vulnerable and its insufficiency is recognized as the main cause of adult acquired flat foot. Some patients have a predisposition without clinically recognized cause, suggesting that individual characteristics play an important role in tendinopathy. Objective was investigated whether genetic variants in matrix metalloproteinases (MMPs) are associated with PTT dysfunction. METHODS: 100 women who presented PTT dysfunction, with histopathological examination of the tendon and magnetic resonance image (MRI) confirming tendinopathy, while 100 asymptomatic women who present intact PPT at MRI constituted the control group were evaluated for MMP-13 g...

Posterior tibial tendon dysfunction is often coupled with various degrees of hindfoot valgus and equinus. Preoperative planning is essential to appropriate procedure choice and surgical efficiency. The purpose of the present study was to assess the anatomy at the harvest site for flexor digitorum longus tendon transfer, specifically at the master knot of Henry. Thirty fresh-frozen below-the-knee cadavers were used for dissection. A standard anatomic approach was performed for posterior tibial tendon debridement and flexor digitorum longus tendon transfer...

PURPOSE: Medial displacement calcaneal osteotomy with flexor digitorum longus transfer is a common treatment for the management of the adult flatfoot associated with posterior tibial tendon dysfunction. In the literature, there is a paucity of information regarding the ability of patients to return to sport and recreational activities after this surgical procedure. The purpose of this retrospective clinical study was to assess the rate and type of athletic activities that patients participated in before and after medial displacement calcaneal osteotomy with flexor digitorum longus transfer...

A 25-year-old man with a pronation-external rotation type of fracture was surgically treated using a fibular plate. Five years later, he underwent resection of bone hyperplasia because of the ankle pain and limitation of range of motion. Thereafter, the left ankle became intermittently painful, which persisted for about one year. He presented at the age of 43 with persistent ankle pain. Physical and image analysis findings indicated a diagnosis of posttraumatic posterior tibial tendinitis, which we surgically treated using tendoscopy...

A tear of the spring ligament is frequently associated with posterior tibial tendon dysfunction. Repair of the damaged spring ligament is an important component of surgical reconstruction in the treatment of posterior tibial tendon dysfunction because it is a major anatomic contributor to the integrity of the medial longitudinal arch, particularly if the dynamic support of the posterior tibial tendon is compromised. Extensive dissection is required for exposure and repair of the ligament because it is a deep-seated structure...

OBJECTIVE: Fluid along the frondiform ligament, the sinus tarsi stem of the inferior extensor retinaculum (IER), can approximate the extensor digitorum longus (EDL), at times simulating tenosynovitis. Our purpose, based on MRI and cadaveric studies, was to further evaluate this scantly described phenomenon, to identify associated findings and to alert the radiologists to the potential pitfall of over diagnosing EDL tenosynovitis. MATERIALS AND METHODS: Two musculoskeletal radiologists retrospectively reviewed the radiology reports and MRI studies of 258 ankle MRI exams, performed at our institution, for fluid along the frondiform ligament extending toward the EDL...

The spring ligament complex is an important stabilizer of the medial ankle, together with the posterior tibial tendon (PTT) and the deltoid ligament complex. Lesions in these stabilizers result in acquired adult flatfoot deformity. The spring ligament complex includes three ligaments: the superomedial calcaneonavicular ligament, the medioplantar oblique calcaneonavicular ligament, and the inferoplantar longitudinal calcaneonavicular ligament. Normal MR imaging anatomy of the spring ligament complex and the PTT are described and illustrated in detail...

BACKGROUND: Abnormalities of the peroneal tendons can frequently be identified on routine MRI of the foot and ankle. Previous studies in the orthopedic literature have discussed the prevalence of abnormal MRI findings in asymptomatic patients, most notably with regards to the spine and shoulder. The purpose of this study was to determine the prevalence of abnormal findings of the peroneal tendons on MRI in asymptomatic individuals. METHODS: We retrospectively reviewed all foot and ankle MRIs from 2 independent time periods that were either performed or reviewed at our institution...

BACKGROUND: Posterior tibial tendon dysfunction is a disabling pathologic flatfoot disorder. Evidence supports the notion that this condition is poorly diagnosed by health-care professionals. In addition, opinion is divided as to the most appropriate assessment and diagnostic techniques used to reflect the progression or stage of the condition. Hence, this study intended to explore the views and opinions of health-care professionals who may be involved in its assessment and diagnosis...

Subtalar joint arthroereisis (STA) can be used in the management of adult acquired flatfoot deformity (AAFD), including posterior tibial tendon dysfunction. The procedure is quick and normally causes little morbidity; however, the implant used for STA often needs to be removed because of sinus tarsi pain. The present study evaluated the rate and risk factors for removal of the implant used for STA in adults treated for AAFD/posterior tibial tendon dysfunction, including patient age, implant size, and the use of endoscopic gastrocnemius recession...

The present study aimed to diagnose complete rupture (CR) and longitudinal rupture (LR) of the posterior tibial tendon (PTT) from the magnetic resonance imaging findings in patients with PTT dysfunction and to analyze and compare the radiographs from each group to identify radiographic indicators related to the progression of PTT injury that would allow the radiographic diagnosis of CR. We evaluated 32 feet in 27 patients with PTT dysfunction (mean age 66.5, range 49 to 82, years). Radiographs were used to acquire weightbearing anteroposterior images of the foot, which were used to measure the talonavicular coverage angle...

BACKGROUND: The recent classifications for posterior tibial tendon dysfunction (PTTD) stage II are based on forefoot deformity, but there is still no consensus regarding a detailed explanation of the clinical condition. The purposes of this study were to clarify the clinical condition of flatfoot deformity using three-dimensional (3D) computed tomography (CT) imaging under loading on both healthy and flat feet and to compare 3D movement of the forefoot in response to load. METHODS: Ten volunteers and 10 PTTD stage II patients with symptomatic flatfoot deformity were examined...

STUDY DESIGN: Controlled laboratory, repeated measures. BACKGROUND: Posterior tibial tendon dysfunction is a common musculoskeletal problem that includes tendon degeneration and collapse of the medial arch of the foot (flatfoot deformity). Ankle-foot orthoses (AFOs) typically are used to correct flatfoot deformity. Correction of flatfoot deformity involves increasing forefoot adduction, forefoot plantar flexion, and hindfoot inversion. OBJECTIVES: To test whether a foot orthosis with a lateral extension reduces forefoot abduction in patients with stage II posterior tibial tendon dysfunction while walking...

The Cobb procedure is useful for addressing stage 2 posterior tibial tendon dysfunction and is often accompanied by a medial displacement calcaneal osteotomy and/or lateral column lengthening. The Cobb procedure can also be combined with selected medial column arthrodesis and realignment osteotomies along with equinus correction when indicated.

REVIEW
James T Maskill, Gregory C Pomeroy
The modified Kidner procedure and flexor digitorum longus tendon transfer are common procedures used today when addressing posterior tibial tendon dysfunction. These techniques are often used in conjunction with a combination of osteotomies to correct flatfoot deformity, and have been proved to be reliable and predictable.
