In this retrospective study, a series of 10 elective patients treated with transfer of the tibialis posterior (TP) tendon for pes cavus and drop foot are described. Since TP transfer completely subtracts the role of this tendon, this cohort of patients provides an opportunity to examine the consequences of tibialis posterior (TP) deficiency. After a mean follow up period of 44.7 months, only one patient showed evidence of strain in the spring ligament but none of the patients in this series developed clinical or radiological evidence of planovalgus deformity...

BACKGROUND: Repairs of chronic Achilles tendon ruptures are technically challenging due to large defects after scar excision. Multiple techniques for repair have been proposed but little consensus on best practice established. This study aims to compare flexor hallucis longus (FHL) transfers versus turndown flaps augmented by FHL transfers. METHODS: Between 2005 and 2015, 49 unilateral repairs of chronic Achilles tendon ruptures were performed. We retrospectively compared the outcomes of 20 patients who underwent FHL transfer with 19 patients who underwent turndown flaps augmented with FHL transfer before surgery and at three time points after surgery (three, six and twelve months)...

BACKGROUND: Extensor hallucis longus (EHL) tendon injuries often occur in the setting of lacerations to the dorsum of the foot. End-to-end repair is advocated in acute lacerations, or in chronic cases when the tendon edges are suitable for tension free repair. Reconstruction with allograft or autograft is advocated for cases not amenable to a primary direct repair. This is often seen in cases with tendon retraction and more commonly in the chronic setting. In many countries the use of allograft is very limited or unavailable making reconstruction with autograft and tendon transfers the primary choice of treatment...

BACKGROUND: In patients with chronic Achilles tendon disorders, Achilles tendon debridement can be supplemented with a tendon transfer, with the flexor hallucis longus tendon (FHL) transfer representing the most common used technique. Our study describes clinical and functional results of patients treated with flexor digitorum longus (FDL) tendon transfer in the treatment of patients with chronic Achilles tendon disorders. METHODS: Retrospective study of prospectively collected data of thirteen patients (15 feet) that underwent FDL tendon transfer as part of the treatment of chronic Achilles tendon disorders...

CASE: A 47-year-old Caucasian woman spontaneously developed an isolated anterior compartment pressure of >100 mm Hg in the left leg. Despite fasciotomies, the musculature was nonviable and required debridement. Following Achilles tendon lengthening, a posterior tibial tendon (PTT) to anterior tibial tendon (ATT) transfer was supplemented with a flexor digitorum longus tendon transfer to the remaining PTT in order to prevent a flatfoot deformity while restoring active dorsiflexion. CONCLUSION: Preservation of the tendinous portion of the ATT during debridement allowed for transfer of the PTT to the ATT using a modified Pulvertaft transfer...

Terminal branches of the superficial fibular nerve are at risk of iatrogenic damage during foot surgery, including hallux valgus rigidus correction, bunionectomy, cheilectomy, and extensor hallucis longus tendon transfer. One terminal branch, the dorsomedial cutaneous nerve of the hallux, is particularly at risk of injury at its intersection with the extensor hallucis longus tendon. Iatrogenic injuries of the dorsomedial cutaneous nerve of the hallux can result in sensory loss, neuroma formation, and/or debilitating causalgia...

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...

REVIEW
J Hamel
Cavovarus deformities in children and adolescents require sound considerations concerning the timing for corrective surgery. Progression can be recognized best by repeated pedographic examination with evaluation of the typical features of cavovarus deformity. Surgical correction consists of a combination of soft tissue release, bony realignment, and restoration of muscle balance. In most cases plantar or medioplantar soft tissue release should be considered, whereas calf muscle lengthening is rarely indicated...

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)...

AIMS: After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age. PATIENTS AND METHODS: The length, width and height of the lateral cuneiform were measured in 43 consecutive patients with unilateral CTEV who had been treated using the Ponseti method...

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...
