The aim of this study is to systematically review and appraise studies assessing the effects of chronic ankle instability (CAI) on kinetics, kinematics and muscle activity during walking and running. The primary search was conducted in PubMed, Embase, CINAHL, AMED and SPORTDiscus. Only studies that compared participants with CAI with healthy participants and assessed kinetics, kinematics or muscle activity during walking or running were included. The risk of bias assessment was conducted using a modified version of the Quality Index checklist...

The os peroneum (OP) is a small sesamoid bone located inside the peroneus longus tendon (PLT), close to the cuboid. The OP can be the cause of pain and can be associated with lesions of the PLT. OP involvement in PLT disorders is frequently misdiagnosed by radiologists. Painful os peroneum syndrome (POPS) refers to a variety of conditions presenting with pain localized on the lateral aspect of the cuboid area. The syndrome can be observed as a consequence of local acute trauma such as ankle sprains or chronic overuse...

A fracture of the os peroneum is a rare cause of ankle and foot pain and is often overlooked and not assumed. Only a few case reports have discussed the different etiologies, options for diagnosis, and therapeutic interventions for acute cases. We present a case of delayed diagnosis of an os peroneum fracture due to a distortion of the ankle that occurred during air sports. Initial diagnostic testing with magnetic resonance imaging demonstrated a rupture of the peroneus longus tendon with no pathologic abnormalities at the peroneus brevis tendon...

OBJECTIVES: Limited literature exists on the sonographic appearance of the posterior tibialis (PTT) and the peroneus brevis (PBT) tendon entheses. We determined the anatomic features and best imaging techniques of normal PTT and PBT using musculoskeletal ultrasound and compared these findings to subjects with inflammatory arthritis. METHODS: Adult subjects were enrolled as: healthy controls (HC), rheumatoid arthritis (RA), and spondyloarthropathy (SpA). Bilateral PTT and PBT entheses were imaged longitudinally, comparing two angles of insonation: perpendicular to the skin surface and 45˚ cephalad...

INTRODUCTION: Neurologic paralysis of the foot due to damage to the central nervous system is primarily caused by a cerebral insult. The ankle-foot orthosis (AFO), which is the classical conservative treatment option, is associated with drawbacks, e.g., increased contractures, limited mobilization from the sitting position, and cosmetic aspects. METHODS: Functional external electrostimulation (FES) is an suitable treatment method for patients with a central lesion and intact peroneal nerve...

Lateral ankle sprains are one of the most common injuries among the physically active subjects. Ankle inversion-eversion laxity is greater and dynamic postural control is less in women compared with men. The purpose of this study was to examine differences in postural sway and its effects on the neuromuscular activities of the ankle stabilizing muscles during the menstrual cycle in young women. Fourteen young women with regular menstrual cycles participated in this experiment. Postural sway and electromyographic signals of the lateral gastrocnemius, peroneus longus (PL), and tibialis anterior (TA) were recorded while the participants performed eight different balance tasks at ovulation and early follicular phase during one full menstrual cycle...

Many of the described labral-reconstruction procedures are purely arthroscopic. This approach only allows segmentary reconstructions. For more extensive reconstructions, surgical dislocation of the hip still represents the more suitable approach. We present an arthroscopy-assisted procedure combined with an anterior mini-open approach, which could be considered for reconstruction of nonrepairable labral lesions located in the posterior aspect of the acetabulum and massive reconstructions in cases of global-pincer femoroacetabular impingement and protrusio acetabuli...

To examine a common plantar tendinous plate for long flexors of the toe and fingers in human embryos, we observed sections of 10 embryos at 5-6 weeks (crown-rump length or CRL 15-21 mm). The heel or tuber of the calcaneus was underdeveloped in 3 embryos with CRL 15 mm and the talus appeared not to be piled up on the calcaneus but these two bones were arranged along the lateromedial axis. As reported in the hand, we demonstrated, in the deep side of tarsal bones, a common tendinous plate formed by a joining of the flexor halluces longus and flexor digitorum longus tendons...

Chul Hyun Park, Woo-Chun Lee
BACKGROUND: The anterior half of the peroneus longus tendon (AHPLT) has been reported to be an effective autograft for ligament reconstruction with respect to strength and safety. However, there is little information regarding donor site morbidity after harvesting the AHPLT. Furthermore, to the best of our knowledge, there has not been a study on the isokinetic evaluation of ankle plantar flexion and eversion after AHPLT harvesting. PURPOSE: To evaluate the clinical and radiographic results after lateral ankle ligament reconstruction using the AHPLT...

Y Tourné, C Mabit
Capsule/ligament lesions of the lateral compartment of the ankle lead to lateral laxity, which is a prime contributor to chronic ankle instability. Lateral ligament reconstruction stabilizes the joint. Exhaustive preoperative clinical and paraclinical work-up is essential. The present article classifies, presents and criticizes the main techniques in terms of long-term stabilization and reduction of osteoarthritis risk. Anatomic ligament repair with reinforcement (mainly extensor retinaculum) or anatomic ligament reconstruction are the two recommended options...

This study examined the effects of regular Tai Chi practice and jogging on the neuromuscular activity of the trunk, hip, and ankle joint muscles of older people during lateral postural perturbation. A total of 42 older people participated in the study and formed the Tai Chi, jogging, and sedentary control groups. Electromyography signals were collected from the peroneus longus, anterior tibialis, gluteus medius, and erector spinae during unpredictable mediolateral perturbation. The Tai Chi group exhibited significantly faster latencies of the tibialis anterior and erector spinae than the control group...

OBJECTIVE: The purpose of this study was to evaluate interrater reliability in the diagnosis of myofascial trigger points (MTrPs) in the tibialis anterior, peroneus brevis, and extensor digitorum longus muscles. METHODS: A reliability research study was performed. Three physical therapists with clinical experience in myofascial pain functioned as raters and randomly and bilaterally evaluated the ankles of 40 subjects in the Madrid public health care system. The absence or presence of MTrPs, nodules in taut bands, patterns of referred pain, local twitch response (LTR), and jump-sign were evaluated...

The assessment of neuromuscular recovery after peripheral nerve surgery has typically been a subjective physical examination. The purpose of this report was to assess the value of gait analysis in documenting recovery quantitatively. A professional football player underwent gait analysis before and after surgery for a peroneal intraneural ganglion cyst causing a left-sided foot drop. Surface electromyography (SEMG) recording from surface electrodes and motion parameter acquisition from a computerized motion capture system consisting of 10 infrared cameras were performed simultaneously...

The anatomical surface markings for the superficial peroneal nerve have been described and it may be preferred for biopsy in cases of suspected vasculitis as biopsy of the peroneus brevis muscle increases diagnostic yield. The procedure is however unfamiliar to many surgeons and the anatomical variability of the subcutaneous part underestimated. Where the nerve has some preserved sensory nerve action potential it may be mapped pre-operatively, greatly facilitating minimally traumatic biopsy with potential logistical and wound healing advantages...

The pronators and supinators play a key role in the medio-lateral stability of the ankle joint complex (i.e. talo-crural and subtalar joints). We hypothesized that each shank muscle has a specific activation pattern determined by its anatomical course around the axes of the subtalar and talo-crural joints. A secondary objective was to examine the effect of foot posture on these activation patterns. Forty-nine young adults (25 normal-arched feet, 24 flat-arched feet) performed maximum voluntary isometric contractions against manual resistance in four movement directions: plantarflexion (PF), dorsiflexion (DF), pronation (PRO) and supination (SUP)...
