We report our technique for split peroneus brevis lateral ankle stabilization using the modified rolling hitch for tendon graft fixation. Applying the modified rolling hitch for tendon grasping in this procedure was useful, and it could decrease the surgical time and avoid the tendon injury caused by the needle.

BACKGROUND: Posterior tibial tendinopathy is a challenging foot condition resulting in pes planus, which is difficult to diagnose in the early stage. Prior to the deformity, abnormal internal load transfer and soft tissue attenuation are anticipated. The objective of this study was to investigate the internal load transfer and strain of the ligaments with posterior tibial tendinopathy, and the implications to pes planus and other deformities. METHODS: A three-dimensional finite element model of the foot and ankle was reconstructed from magnetic resonance images of a 28-year-old normal female...

Ruptures of the tendon of the tibialis anterior muscle tend to occur in the context of degenerative impairments. This mainly affects the distal avascular portion of the tendon. Owing to the good compensation through the extensor hallucis longus and extensor digitorum muscles, diagnosis is often delayed. In addition to the clinical examination, magnetic resonance inaging (MRI) diagnostics are of particular importance, although damage or rupture of the tendon can also be demonstrated sonographically. Therapeutic measures include conservative or operative measures, depending on the clinical symptoms...

Subtalar joint arthroereisis (SJA) has been introduced to control the hyperpronation in cases of flatfoot. The objective of this study is to evaluate the biomechanical consequence of SJA to restore the internal stress and load transfer to the intact state from the attenuated biomechanical condition induced by posterior tibial tendon dysfunction (PTTD). A three-dimensional finite element model of the foot and ankle complex was constructed based on clinical images of a healthy female (age 28 years, height 165 cm, body mass 54 kg)...

In anterior transfer of the tibialis posterior tendon, the tendon was harvested using two incisions, the first at its attachment point on the navicular bone and second on the medial side of the leg above the medial malleolus. To provide the maximum tendon length, the second incision needs to be as proximal as possible but injury to the muscle origin must be avoided. The purpose of this study is to establish the location of the second incision that yields the greatest tendon length. Forty-five unpaired embalmed cadaveric legs were dissected...

BACKGROUND: Fibular hemimelia is a congenital disorder that is characterized by the absence of the fibula that could be either partial or complete. Successful management aims to restore normal weight bearing and normal limb length. The introduction of the Ilizarov method of limb lengthening has provided an attractive alternative to amputation. During lengthening, the tight posterolateral soft-tissue structures, the thick fibrous fibular band, and the shortened Achilles tendon become tighter and transfer a valgus force to the talus and calcaneus, further aggravating the deformity...

Justin D Orr, Kenneth A Heida
Posteriorly based osteochondral lesions of the talus (OCLTs) are relatively rare, and when they are symptomatic and not amenable to traditional arthroscopic treatment techniques, they may require osteochondral graft transfer procedures, such as the osteochondral autograft transfer system (OATS) procedure. Historically described osteotomies to gain perpendicular access to these OCLTs, while excellent techniques, present many possible postoperative morbidities. This technical tip describes the use of a prone position midline Achilles tendon-splitting approach, a well-described approach to the posterior ankle and hindfoot, to perform osteochondral autograft transfer without need for any malleolar osteotomies...

OBJECTIVE: To present interdisciplinary practical guidance for the assessment and treatment of spastic equinovarus foot after stroke. RESULTS: Clinical examination and diagnostic nerve block with anaesthetics determine the relative role of the factors leading to spastic equinovarus foot after stroke: calf spasticity, triceps surae - Achilles tendon complex shortening and dorsiflexor muscles weakness and/or imbalance. Diagnostic nerve block is a mandatory step in determining the cause(s) of, and the most appropriate treatment(s) for, spastic equinovarus foot...

Human adipose-derived microvascular endothelial cells (HAMEC) and mesenchymal stem cells (MSC) have been shown to bear angiogenic and vasculogenic capabilities. We hypothesize that co-culturing HAMEC:MSC on a porous biodegradable scaffold in vitro, later implanted as a graft around femoral blood vessels in a rat, will result in its vascularization by host vessels, creating a functional vascular flap that can effectively treat a range of large full-thickness soft tissue defects. HAMEC were co-cultured with MSC on polymeric 3D porous constructs...

Novel and combined tissue transfers from the lower extremity provide new tools to combat soft tissue defects of the hand, foot, and ankle, or fracture nonunion. Flaps can be designed for special purposes, such as providing a gliding bed for a grafted or repaired tendon or for thumb or finger reconstruction. Propeller flaps can cover soft tissue defects of the leg and foot. In repairing severe bone and soft tissue defects of the lower extremity, combined approaches, including external fixators, one-stage vascularized bone grafting, and skin or muscle flap coverage of the traumatized leg and foot, have become popular...

Favorable results have been reported for tibialis posterior tendon transfers, which can effectively restore the dorsiflexion of the ankle and normal heel-to-toe gait. However, the commonly used methods for anchoring the transplanted tendon have some drawbacks. Therefore, we developed a new tendon-anchoring method to improve fixation of the transferred tendon and reduce the related complications. The new method entails tying the anchoring suture to the navicular bone instead of the button on the plantar foot to avoid wound complications...

Introduction: The potential of the medial calf integument, as donor site for a free flap based on musculocutaneous branches of the medial sural artery, was first identified by Taylor and Daniel, following cadaver investigation. In 1981, Pontén described the fasciocutaneous sural flap as a reconstructive option for soft tissue loss of the lower extremity, particularly around the knee. Two years later, Donski and Fogdestram presented the distally based fasciocutaneous flap from the sural region followed by Montegut and Allen who considered the sural artery perforator flap as a viable alternative for the gastrocnemius myocutaneous flap...

REVIEW
Pooya Hosseinzadeh, Derek M Kelly, Lewis E Zionts
The Ponseti method to treat idiopathic clubfoot deformity has proven to be reliable, and several centers have reported excellent outcomes. Although the method has been dependable in obtaining initial correction of the foot, relapse rates ranging from 26% to 48% have been reported. When a relapsed deformity is detected early, treatment with a short series of manipulations and cast applications followed by resumption of postcorrective bracing may be all that is required to regain and maintain correction. In patients aged >2...

PURPOSE: Early stage adult acquired flatfoot deformity (AAFD) is traditionally treated with osteotomy and tendon transfer. Despite a high success rate, the long recovery time and associated morbidity are not sufficient. This study aims to evaluate the functional and radiological outcomes following the use of the arthroereisis screw with tendoscopic delivered PRP for early stage AAFD. METHODS: Patients with stage IIa AAFD who underwent the use of the arthroereisis screw with tendoscopic delivered PRP with a minimum follow-up time of 24 months were retrospectively evaluated...

Background Despite the low incidence of deep vein thrombosis (DVT) in foot and ankle surgery, some authors report a high incidence of symptomatic DVT following Achilles tendon rupture. The purpose of this study was to identify DVT risk factors inherent to Achilles tendon repair to determine which patients may benefit from prophylaxis. Methods One hundred and thirteen patient charts were reviewed following elective and nonelective Achilles tendon repair. For elective repair of insertional or noninsertional Achilles tendinopathy, parameters examined included lateral versus prone positioning and the presence versus absence of a flexor hallucis longus transfer...
