Osteoarthritis progression can be related to the external knee adduction and flexion moments during walking. Lateral foot wedges and knee braces have been used as treatment for osteoarthritis, but little is known about their influence on knee joint moments generated in the sagittal and frontal planes. Therefore, the aim of the present study was determine the effects of the isolated and combined use of valgus knee brace and lateral wedge foot orthotic on peak forces and moments during gait in knee osteoarthritis patients...

Intraneural ganglion cysts that occur within the common peroneal nerve are a rare cause of foot drop. The current standard of treatment for intraneural ganglion cysts involving the common peroneal nerve involves (1) cyst decompression and (2) ligation of the articular nerve branch to prevent recurrence. Nerve transfers are a time-dependent strategy for recovering ankle dorsiflexion in cases of high peroneal nerve palsy; however, this modality has not been performed for intraneural ganglion cysts involving the common peroneal nerve...

Subtalar joint arthroereisis (SJA) has been introduced to control the hyperpronation in cases of flatfoot. The objective of this study is to evaluate the biomechanical consequence of SJA to restore the internal stress and load transfer to the intact state from the attenuated biomechanical condition induced by posterior tibial tendon dysfunction (PTTD). A three-dimensional finite element model of the foot and ankle complex was constructed based on clinical images of a healthy female (age 28 years, height 165 cm, body mass 54 kg)...

Leg and foot problems in childhood are common causes of parental concern. Rotational problems include intoeing and out-toeing. Intoeing is most common in infants and young children. Intoeing is caused by metatarsus adductus, internal tibial torsion, and femoral anteversion. Out-toeing is less common than intoeing and occurs more often in older children. Out-toeing is caused by external tibial torsion and femoral retroversion. Angular problems include genu varum (bowleg) and genu valgum (knock knee). With pes planus (flatfoot), the arch of the foot is usually flexible rather than rigid...

BACKGROUND: When walking in footwear with a positive "heel sole differential", the sagittal kinematics of the base of the footwear appear to mimic normal barefoot foot kinematics, creating an "effective foot," yet sagittal shank, thigh, and trunk kinematics appear to remain unchanged. These observations have not been quantified. OBJECTIVES: To quantify these observations by assessing the effect of different heel sole differentials on sagittal shank and foot segment kinematics of able-bodied walking...

We present a case of fibular insufficiency (stress) fracture in a patient with pre-existing asymptomatic advanced tibialis posterior dysfunction. The patient had severe planovalgus (flat foot) deformity but no pain before the injury; hence had never sought any treatment. She was first treated conservatively for the fracture which failed to control the deformity and had ongoing symptoms. She eventually required tibio-talo-calcaneal fusion. To the best of our knowledge, this is the first case report of this condition in the English literature...

BACKGROUND: Orthoses commonly are prescribed to children with cerebral palsy (CP) to provide foot correction and to improve ambulatory function. Immediate effects of ankle foot orthosis (AFOs) have been investigated, but long-term kinematic effects are lacking clinical evidence. OBJECTIVE: To determine changes in 3-dimensional ankle and foot segment motion in pediatric patients with CP between initial and follow-up visits (18-month average time differences) in both barefoot gait and gait with their AFO...

Musculoskeletal anatomy is widely known to have components that stray from the norm in the form of variant muscle and tendon presence, absence, origin, insertion, and bifurcation. Although these variant muscles and tendons might be deemed incidental and insignificant findings by most, they can be important contributors to pathologic physiology or, more importantly, an option for effective treatment. In the present case report, we describe a patient with phocomelia and Müllerian abnormalities secondary to in utero thalidomide exposure...

BACKGROUND: Limited data are available comparing the results of lateral sesamoidectomy and medial sesamoidectomy for the treatment of fractures recalcitrant to nonoperative treatment interventions. The hypothesis of this study was that sesamoidectomy for either lateral or medial sesamoid fractures would not change radiographic alignment of the first ray given the use of identical reconstruction of the plantar plate, intersesamoid ligament, and plantar ligament complex at the time of surgery...

Markus Walther
BACKGROUND: The most common cause of degeneration of the posterior tibial tendon is a congenital valgus deformity of the calcaneus. Other associated pathologies are forefoot supination, forefoot abduction and shortening of the gastrocnemius muscle. DIAGNOSTICS: Loaded x‑rays of the foot in three planes as well as the hindfoot alignment view enable evaluation of the axis of the foot under static loading conditions. The posterior tibial tendon can be imaged with ultrasound and magnetic resonance imaging (MRI)...

Tibial coronal inclination is often recognized in everyday life, but the compensatory kinematic changes to maintain plantigrade of the hindfoot in response to tibial coronal inclination remain unclear. Lower legs and foot specimens obtained from seven human cadavers were loaded vertically with traction of Achilles' tendon in different tibial inclinations: 0° (neutral), 5°, and 10° medial inclination, and 5° and 10° lateral inclination. The orientations of the tibia, talus, and calcaneus were recorded under vertical load by a three-dimensional digitizing stylus...

BACKGROUND: Ankle foot orthoses (AFOs) are orthotic devices that can be used to normalize the walking pattern of children with cerebral palsy (CP). One of the aims of orthotic management is to produce a more normal gait pattern by positioning joints in the proper position to reduce pathological reflex or spasticity. OBJECTIVE: To conduct a systematic review of the literature and establish the effect of treatment with various types of AFOs on gait patterns of children with CP...

The knee adduction moment is consistently used as a surrogate measure of medial compartment loading. Foot orthoses are designed to reduce knee adduction moment via lateral wedging. The 'dose' of wedging required to optimally unload the affected compartment is unknown and variable between individuals. This study explores a personalised approach via three-dimensional printed foot orthotics to assess the biomechanical response when two design variables are altered: orthotic length and lateral wedging. Foot orthoses were created for 10 individuals with symptomatic medial knee osteoarthritis and 10 controls...

Bryant Ho, Judith Baumhauer
An estimated 40% of the US population have foot problems.Of all patients aged over 50 years, 2.5% report degenerative arthritis of the first metatarsophalangeal (MTP) joint, termed 'hallux rigidus'. First MTP osteoarthritis is the most common arthritic condition in the foot.Progression of great toe arthritis is associated with pain and loss of motion. Non-surgical intervention begins with shoe modifications and orthotics designed to limit MTP motion.In patients with mild arthritis, operative procedures focus on removing excess osteophytes (cheilectomy) to prevent dorsal impingement with or without a concomitant osteotomy (Moberg) to improve or shift range of motion into a less painful arc...
