INTRODUCTION: 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...

Several brain structures including the brainstem, the cerebellum and the frontal cortico-basal ganglia network, with the primary and premotor areas have been shown to participate in the functional organization of gait initiation and postural control in humans, but their respective roles remain poorly understood. The aim of this study was to better understand the role of the supplementary motor area (SMA) and posterior cerebellum in the gait initiation process. Gait initiation parameters were recorded in 22 controls both before and after continuous theta burst transcranial stimulation (cTBS) of the SMA and cerebellum, and were compared to sham stimulation, using a randomized double-blind design study...

BACKGROUND: Multiple studies have demonstrated a higher risk of graft failure after anterior cruciate ligament reconstruction with allograft, but limited data are available comparing outcomes of posterior cruciate ligament reconstruction (PCLR) with autograft versus allograft. PURPOSE: To compare the clinical outcomes of autograft versus allograft for primary PCLR. STUDY DESIGN: Systematic review. METHODS: A systematic review was performed by searching PubMed, the Cochrane Library, and EMBASE to locate studies (level of evidence I-III) comparing clinical outcomes of autograft versus allograft in patients undergoing primary PCLR with the conventional transtibial technique...

Irreducible ankle fractures are a relatively rare phenomenon. We present a case of a pronation abduction-type ankle fracture that was irreducible in the emergency room despite sedation. The patient was taken to the operating room, where the posterior tibialis tendon and retinaculum, deltoid ligament, and anteromedial capsule were found to be trapped within the joint. After removal of the tissue, alignment was restored. The patient did well clinically and was advanced to full weightbearing at 6 weeks. This is, to the best of our knowledge, the first report of entrapment of all 4 anatomic structures, preventing closed reduction...

Extra-articular manifestations of gout can present in several ways, including tenosynovitis. We present a rare case of acute tibialis posterior gouty tenosynovitis. An 82-year-old man with a history of well-controlled gout presented with acute onset of left ankle pain, occurring without inciting event. The medial ankle was slightly erythematous with moderate dorsal-medial swelling and mild dorsal-lateral swelling, with severe tenderness to palpation over the medial retro-malleolar region. Range of motion and manual muscle testing were pain limited throughout...

BACKGROUND: Patients on anticoagulation or antiplatelet therapy may be at higher risk for bleeding complications following intramuscular chemodenervation injections. Musculoskeletal ultrasound may be able to reduce the risk of bleeding complications by providing real-time visualization of vascular structures and postinjection monitoring. Limited data exist addressing the risk of bleeding complications following ultrasound-guided botulinum neurotoxin intramuscular chemodenervation procedures in the setting of anticoagulation or antiplatelet therapy...

The purpose of this study was to examine exercise effects on muscle water T2 in patients with Duchenne muscular dystrophy (DMD). In 12 DMD subjects and 19 controls, lower leg muscle fat (%) was measured by Dixon and muscle water T2 and R2 (1/T2) by the tri-exponential model. Muscle water R2 was measured again at 3 hours after an ankle dorsiflexion exercise. The muscle fat fraction was higher in DMD participants than in controls (p < .001) except in the tibialis posterior muscle. Muscle water T2 was measured independent of the degree of fatty degeneration in DMD muscle...

Open ankle dislocations without fracture are rare injuries. Dislocation or interposition of adjacent tendons are a rare associated feature of ankle fracture-dislocation. We report an extremely unusual case of open ankle dislocation without fracture with concurrent tibialis posterior tendon interposition through the interosseous space that was detected incidentally on computed tomography. We highlight the clinical, radiologic, and intraoperative features to avoid missing similar diagnoses.

To improve our understanding of early disease mechanisms and find reliable biomarkers of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease, we measured electromyogram (EMG) activity in hind limb muscles of SOD1G93A mice. In contrast to clinical diagnostic measures using EMGs, which are performed on quiescent patients, we monitored activity during treadmill running in order to detect presymptomatic changes in motor patterning. Chronic EMG electrodes were implanted into vastus lateralis (VL), biceps femoris posterior (BFP), lateral gastrocnemius (LG), and tibialis anterior (TA) in mice from postnatal day (P) 55-100, and results were assessed using linear mixed models...

OBJECTIVES: Extensor carpi ulnaris (ECU) and tibialis posterior (TP) tendons are often involved in RA and the present aim was to examine by ultrasound (US) their frequency of inflammation and sensitivity to change in comparison to joint involvement as well as clinical examinations. METHODS: US, clinical and laboratory assessments were performed when starting biologic DMARD (bDMARD) and after 1, 2, 3, 6 and 12 months including bilateral grey-scale (GS) and power Doppler (PD) semi-quantitatively (0-3) scoring of ECU and TP tendons and 18 joints...

We explored unintentional drifts in voluntary whole-body sway tasks following the removal of visual feedback. The main hypothesis was that the unintentional drifts were produced by drifts of referent coordinates for salient performance variables. Young healthy subjects stood quietly on a force platform and also performed voluntary body sway at 0.5 Hz both in the anterio-posterior and medio-lateral directions. Visual feedback on the center of pressure (COP) coordinate was provided and then turned off. During quiet stance trials, the subjects matched the initial COP coordinate with a target shifted by 3 cm anterior, posterior, left, or right from the coordinate during natural standing and activated the right tibialis anterior to 30% of its maximal voluntary contraction...

Irreducible ankle fracture-dislocations are very rare entities. The present case report demonstrates an unusual finding of tibialis posterior and flexor digitorum longus tendons interposed in the tibiofibular joint impairing successful closed reduction of ankle fracture-dislocation. A 45-year-old patient presented with a bimalleolar pronation-external rotation ankle fracture-dislocation after a motorcycle accident. Attempts to perform closed reduction before surgery were unsuccessful. Subsequent urgent open reduction and internal fixation surgical management revealed interposition of the tibialis posterior and flexor digitorum longus tendons in the tibiofibular joint...

BACKGROUND: Classification systems developed in the field of posterior tibialis tendon dysfunction omit to include dynamic measurements. Since this may negatively affect the selection of the most appropriate treatment modality, studies on foot kinematics are highly recommended. Previous research characterised the foot kinematics in patients with posterior tibialis tendon dysfunction. However, none of the studies analysed foot segmental motion synchrony during stance phase, nor compared the kinematic behaviour of the foot in presence of different posterior tibialis tendon dysfunction stages...

We studied the short-latency (SL) postural effects of axial impulses in 11 subjects (22 ± 2 years old). Recordings were made bilaterally from soleus and tibialis anterior (TA) muscles. We confirmed that with leaning anteriorly and posteriorly, reflex EMG increases occurred in both muscle groups at short latency following brief perturbations applied over C7 or the sternum (soleus mean latencies 57.5 and 66.4 ms; TA mean 51.7 and 55.4 ms, respectively). While the size of the SL reflexes was affected by the direction of lean when standing we found that light touch did not affect the amplitudes or latencies significantly...

BACKGROUND: There is an increasing interest in the operative treatment of deltoid ligament disruption in the setting of chronic ankle instability. Understanding the vascular anatomy of the deltoid complex is beneficial when considering operative procedures on the medial ankle and may provide insight into factors that lead to chronic deltoid insufficiency and ankle instability. METHODS: Thirty-two pairs of cadaveric specimens (64 total legs) were amputated below the knee, and the tibialis anterior, tibialis posterior, and peroneal arteries were injected with India ink and Ward's blue latex...

Ankle fractures with an associated posterior tibialis tendon (PTT) rupture are rare injuries and have only been described in a number of case reports. These prior reports include patients that had an open fracture and/or an associated medial malleolar fracture component. In this unique case report, we present a patient that sustained a closed bimalleolar-equivalent ankle fracture/dislocation without medial malleolar involvement which was irreducible due to a PTT rupture and subsequent distal segment interposition in the tibiotalar joint...
