Hindfoot motion following reconstruction for posterior tibial tendon dysfunction.

Introduction: Due to advances in technology, segmental gait analysis of the foot is now possible and can elucidate hindfoot deformity in persons with posterior tibial tendon dysfunction (PTTD). This study evaluated the motion of the hindfoot and ankle power following surgical reconstruction for PTTD utilizing a segmental foot model during gait.

Materials And Methods: Twenty patients who underwent posterior tibial tendon reconstruction for Stage 2 PTTD using transfer of the flexor digitorum longus tendon to the navicular tuberosity, reconstruction of the calcaneo-navicular ligament complex, and a medial displacement calcaneal osteotomy were evaluated at a minimum followup of 1 year.

Locomotor treadmill training with partial body-weight support before overground gait in adults with acute stroke: a pilot study.

Objective: To investigate the impact of locomotor treadmill training with partial body-weight support (BWS) before the initiation of overground gait for adults less than 6 weeks poststroke.

Design: Parallel group, posttest only.

Setting: Inpatient rehabilitation center.

Physical properties, durability, and energy-dissipation function of dual-density orthotic materials used in insoles for diabetic patients.

Background: Patients with neuropathic conditions may develop plantar bony deformities through neuropathic collapse, frequently placing the skin and soft tissues at risk. Orthoses have been used to accommodate and distribute plantar pressures over a large surface area, thereby minimizing peak loading pressures in small regions and reducing the risk of ulceration.

Methods: A previously described bony prominence model (Brodsky et al.

Prospective gait analysis in patients with first metatarsophalangeal joint arthrodesis for hallux rigidus.

Background: Arthrodesis of the first metatarsophalangeal (MTP) joint is a common procedure with a proven long-term success rate. However, there is limited scientific information on its functional results. There is little data in the literature about changes in gait parameters after first MTP joint arthrodesis.

Unloading mechanism in the total contact cast.

Background: The effectiveness of total contact casts is postulated to be due to the reduction of plantar pressure. We investigated plantar loads to evaluate the mechanism by which total contact casts off-load the plantar surface of the foot to determine if it is the intimate molding of the weightbearing plantar surface or if a below-knee cast is necessary.

Methods: Plantar pressures and forces in a total contact cast (TCC) were recorded in 12 healthy subjects, using the Pedar (Novel GmbH, Munich, Germany) pedobarographic system.

Knee bracing for unicompartmental osteoarthritis.

Unicompartmental osteoarthritis of the knee affects millions of individuals. Most nonsurgical management of this progressive disease is primarily directed at reducing inflammation and pain with medication. Evidence supports the clinical efficacy of bracing for managing osteoarthritis of the knee.

Dynamic knee motion in anterior cruciate impairment: a report and case study.

Knee motion has been routinely analyzed using radiographic techniques in a static setting. Over the past decade, techniques of in vivo dynamic knee motion analysis have emerged, which have shed light on normal and pathologic knee motion. Most of these methods are either invasive or restricted to small indoor laboratories.

Functional outcome of arthrodesis of the first metatarsophalangeal joint using parallel screw fixation.

Background: Arthrodesis of the first metatarsophalangeal (MTP) joint is a reliable procedure for a painful hallux. Most studies focus on the surgical results rather than the functional outcome for the patient. Therefore, we examined the effects of first MTP joint arthrodesis on activities of daily living and recreational activities.

Sutureless avascular meniscal repair with a photoactive naphthalimide compound: a preliminary animal study.

Purpose: The purpose of this study was to evaluate the ability of 2 new photoactive naphthalimide compounds to repair a lesion in the avascular zone of the meniscus.

Type Of Study: In vivo animal study.

Methods: Ten Barbados sheep were used as the animal model.

Photochemical tissue bonding using monomeric 4-amino-1,8-naphthalimides.

Certain substituted naphthalimides have been shown to produce, on photochemical activation, mechanically viable bonds between a variety of tissue surfaces. It is believed that these compounds act as photochemically activated oxidants, catalyzing the formation of reactive intermediates in the extracellular matrices of approximated tissue surfaces. The condensation of these intermediates results in the formation of crosslinks between the intimate surfaces.

The effect of ankle position on plantar pressure in a short leg walking boot.

Short leg walking boots have been shown to be an effective alternative to total contact casting for the reduction of plantar pressure. Conventional theory indicates that placing the ankle in different positions may affect the plantar pressure and ultimately the healing time for a plantar ulcer. This study attempted to determine the changes in plantar pressures due to alterations in the position of the ankle angle in a walking boot.

Plantar pressures in fiberglass total contact casts vs. a new diabetic walking boot.

The objective of this study was to determine in healthy individuals whether the Bledsoe Diabetic Conformer Boot reduces plantar pressures as well as a fiberglass total contact cast. Eighteen normal subjects, without any prior foot or ankle problems, were recruited for this study. Plantar pressures were measured using the Novel Pedar in-shoe pressure measurement system.

First metatarsophalangeal arthrodesis: a clinical, pedobarographic and gait analysis study.

This study investigated the results of first metatarsophalangeal (MTP) arthrodesis in terms of clinical outcome measures, plantar pressure distribution, and gait patterns. Ten feet in nine patients with severe hallux rigidus (HR) who underwent first MTP arthrodesis were studied. The preoperative evaluation included a subjective questionnaire, physical exam, AOFAS hallux score, radiographs and dynamic pedobarography (EMED).

Reduction of medial compartment loads with valgus bracing of the osteoarthritic knee.

Background: Patients with medial compartment osteoarthritis of the knee may be treated nonoperatively with adjustable valgus bracing.

Hypothesis: Valgus bracing reduces load on the medial compartment through the application of an external valgus moment about the knee, resulting in pain relief.

Study Design: Prospective cohort study.
