Previous history of medial tibial stress syndrome (MTSS) is a risk factor for MTSS relapse, which suggests that there might be some physical factors that are related to MTSS development in runners with a history of MTSS. The relationship between MTSS and muscle stiffness can be assessed in a cross-sectional study that measures muscle stiffness in subjects with a history of MTSS, who do not have pain at the time of measurement, and in those without a history of MTSS. The purpose of this study was to compare the shear elastic modulus, which is an index of muscle stiffness, of all posterior lower leg muscles of subjects with a history of MTSS and those with no history and investigate which muscles could be related to MTSS...

BACKGROUND: Despite the high rate of initial success using the Ponseti method to manage idiopathic clubfoot deformity, relapse continues to be a problem. We surveyed the Pediatric Orthopedic Society of North America (POSNA) members about their experience with relapsed deformity following the initial correction of clubfeet. METHODS: We created a survey to focus on the management of clubfeet after initial correction of deformity. The survey included questions on postcorrective bracing, clinical findings used to identify relapse, the observed frequency of relapsed deformity, and how relapses are managed...

The accessory navicular bone is one of the most common accessory ossicles of the foot. Fewer than 1% of accessory navicular bones are symptomatic, and most of these are type II accessory navicular bones. A separation of the synchondrosis is considered one of the main causes of pain. After an injury to the synchondrosis has resulted in a chondro-osseous disruption, the combined forces of tension and shear from the posterior tibial tendon and the foot aggravate the injury and prevent it from healing. Fusion of the synchondrosis is a logical surgical treatment option if the pain is recalcitrant to conservative measures...

Rupture of the tibialis posterior tendon associated with ankle fracture is rare and difficult to diagnose. This rupture can be easily overlooked because the clinical examination is limited owing to acute pain related to a closed ankle fracture. Complete rupture of the tibialis posterior tendon can be identified by a loss of tension during ankle fracture fixation, but partial rupture is more difficult to detect because the tibialis posterior tendon can maintain its tension. A few cases of complete rupture of the tibialis posterior tendon combined with ankle fracture have been reported...

RATIONALE: Ankle syndesmotic injuries occasionally require long-term therapy for recovery and can result in tendon injury. Posterior tibial tendon dysfunction (PTTD) is an acquired deformity that can cause flatfoot deformity. The current nonoperative management of PTTD includes nonsteroidal antiinflammatory drugs (NSAIDs), orthopedic devices. Although various treatment options have been attempted, optimal treatments for each stage of the condition are debated. Polydeoxyribonucleotide (PDRN) is effective in healing of chronic wounds associated with tissue damage by attracting tissue growth factors...

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)...
