Arthroscopy is an important and minimally invasive diagnostic and therapeutic tool. However, the risk of injury to the neurovascular structures around the portals exists during arthroscopy of the ankle. In the present study, we measured the distance between each portal and the adjacent neurovascular structures with the foot in plantarflexion and dorsiflexion in the Japanese population. Standard anterolateral (AL), anteromedial, posterolateral (PL), and posteromedial portal positions were identified in 6 fresh adult cadaveric feet...

Dancing on pointe and relevé requires extreme plantar flexion of the talo-crural joint. Hence, these positions may lead to posterior ankle impingement syndrome (PAIS). PAIS often coincides with flexor hallucis longus tendinopathy (FHL tendinopathy, or "dancers' tendinitis"). Both injuries can appear in isolation as well. The goal of this review is to evaluate the results and the available levels of evidence of conservative and operative treatment (both open and endoscopic) of PAIS and FHL tendinopathy in dancers...

Posterior ankle impingement syndrome (PAIS) is a painful, usually limited plantar flexion of the ankle joint due to soft tissue impingement or a bony impediment often coinciding with tendinopathy of the flexor hallucis longus (FHL) behind the medial malleolus. In persistent complaints, the bony impediment is removed, the tunnel of the FHL tendon is released, or a combination of both procedures has traditionally been performed by open surgery. In 2000, an endoscopic surgical technique for PAIS and FHL tendinopathy was introduced...

Posterior ankle impingement syndrome (PAIS), the result of posterolateral soft tissue or bony impingement of the ankle, and tendinopathy of the flexor hallucis longus (FHL tendinopathy) in the ankle are common in dancers. If conservative treatment of these conditions fails to produce adequate results, surgical intervention might be necessary. However, outcomes of treatment by open surgery for these diagnoses have been described only in small series of dancers. For this study, data were extracted from clinical files and operative reports of an orthopaedic surgery clinic specialized in dance medicine...

The purpose of the present study was to quantify the learning curve for arthroscopic os trigonum excision using the log-linear model. Twenty-three consecutive feet underwent arthroscopic os trigonum excision and release of the flexor hallucis longus. The required time from the beginning of shaving of the soft tissue until completion of os trigonum excision and release of the flexor hallucis longus (van Dijk time) was recorded. Regression analysis was applied to predict the required time on the basis of the cumulative case volume after logarithmic transformation of both statistics...

Talus fracture of the medial tubercle of the posterior process is rare. This type of fracture can be easily missed, because it is difficult to identify on plain radiographs of the ankle. Oblique radiographs with external rotation, computed tomography, and magnetic resonance imaging (MRI) of the ankle are useful for making an accurate diagnosis. However, even with an early diagnosis, the treatment guidelines for talus fractures of the posterior medial tubercle have not yet been established. The flexor hallucis longus (FHL) tendon, which passes through the groove between the medial and lateral tubercles of the posterior process of the talus, can interpose between the fracture sites and interrupt fracture reduction...

BACKGROUND: The plantar foot muscles and plantar fascia differ between different foot postures. However, how each individual plantar structure contribute to foot posture has not been explored. The purpose of this study was to investigate the associations between static foot posture and morphology of plantar foot muscles and plantar fascia and thus the contributions of these structures to static foot posture. METHODS: A total of 111 participants were recruited, 43 were classified as having pes planus and 68 as having normal foot posture using Foot Posture Index assessment tool...

BACKGROUND: Surgical management of chronic Tendo Achillis (TA) ruptures usually requires tendon grafting procedures. Several techniques have been described. We examined the outcome of three different less invasive (incisions length less than 3 cm) tendon transfer techniques in the management of patients with a chronic rupture of the TA. METHODS: Of 62 patients (39 males and 23 females; mean age 44.8 years; range 29.3-62 years) with chronic TA ruptures managed operatively, 21 patients had a ≥6cm gap and underwent free ipsilateral semitendinosus (ST) graft (21 patients), whereas patients with smaller gaps had either ipsilateral peroneus brevis (PB) (20 patients) or ipsilateral flexor hallucis longus (FHL) transfer (21 patients)...

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: 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...

Longitudinal flexor hallucis longus (FHL) tendon tears are sometimes complicated by posterior ankle impingement syndrome (PAIS), especially in ballet dancers. In recent years, PAIS has been treated endoscopically, but it is difficult to suture FHL tendon tears endoscopically. In this report, we describe how to suture the FHL tendon endoscopically with the Meniscal Viper Repair system (Arthrex, Naples, FL). Without our endoscopic technique, when a patient is found to have a longitudinal tear of the FHL under endoscopy, we must choose to either neglect the tear or convert to an open repair...

BACKGROUND: Chronic Achilles tendon ruptures can lead to reduced power of plantar flexion in the ankle with impaired gait ability. The open 1- or 2-incision technique for flexor hallucis longus transfer has proven good functional outcome but has the disadvantage of relatively extensive surgery performed at a vulnerable location. To reduce the risk of soft tissue problems, the flexor hallucis longus transfer can be performed endoscopically. MATERIAL AND METHOD: An endoscopic technique for flexor hallucis longus transfer is presented together with the experiences from the first six patients operated with this method...

Triggering of the toes is rare, with isolated cases reported in the literature involving predominantly the flexor hallucis longus (FHL) tendon, a condition known as "hallux saltans" (HS). We report the dynamic sonographic findings of a 42-year-old female with a 2-month history of ankle pain and triggering of right hallux, consistent with HS. Sonography demonstrated tenosynovitis and focal thickening of FHL at the level of hindfoot, with a fibrous band adjacent to the tendon. Dynamic ultrasound showed triggering and snapping of FHL tendon during hallux flexion and extension, respectively...

Wide-awake surgery has potential advantages for treating extensor or flexor tendon injury. We present a case of chronic extensor hallucis longus injury treated with turn-down reconstruction using wide-awake surgery with a selective nerve block. To the best of our knowledge, this is the first such case reported. The patient had dropped a knife proximal to the right hallux metatarsophalangeal joint. Because direct suturing was thought to be difficult, turn-down reconstruction was performed under a selective nerve block...
