The midtarsal joint, also known as the Chopart or the transverse tarsal joint, is composed of the talonavicular and calcaneocuboid articulations.(1) Midtarsal joint dislocations are rare injuries given the strong periarticular ligamentous support.2, 3 Medial, lateral, dorsal, and rarely plantar dislocations have been reported from multiple high-energy mechanisms.4, 5 We describe the case of a 24-year-old male who sustained talonavicular and calcaneocuboid plantar dislocations associated with a middle and lateral intercuneiform dislocation, open proximal 5th metatarsal fracture, 2nd-4th metatarsal base fractures, and lateral cuneiform fracture...

OBJECTIVE: We present a preliminary study of plantar pressure control with visual feedback in healthy volunteers by using internal or external focus attentional focalization. The objectives are to decrease the pressure under the right heel of 70%. MATERIAL/PATIENTS AND METHODS: Twenty healthy volunteers were randomized into 2 groups using either internal or external focus. Plantar pressures were recorded using 3 captors under each heel, on the heads of 1st and 5th metatarsals as well as under the calcanean tuberosity (Winshoe device, Medicapteurs C)...

INTRODUCTION AND OBJECTIVES: There are several various accessory ossicles and sesamoid bones that can be seen throughout the foot and ankle, with reported incidence of 21.2% and 9.6%, respectively. Accessory ossicles and sesamoid bones usually remain asymptomatic until an inciting event (trauma, overuse) occurs and can then cause pain or degenerative changes. They can also be found in routine imaging. One of these confusing findings are lesser metatarsal sesamoids, which are a rare occurrence...

The treatment of Zone 1 fractures of the 5th metatarsal base with >2mm of displacement remains controversial. We prospectively analyzed 29 patients with 5th metatarsal base fractures (Zone 1) during 2009-2014. Radiography was performed to assess the degree of fracture gap and metatarsal length. Patients with gaps of 2mm or less were treated conservatively using a short leg cast or splint (Group A), while patients with fracture gap >2mm were randomly assigned to one of two groups. Group B patients were managed with open reduction and internal fixation (ORIF), and Group C patients were placed in a short leg cast only...

INTRODUCTION: Differentiating the severity of acute ankle injuries is a common problem in the emergency department (ED). The Ottawa Foot and Ankle Rules (OFAR) were designed to obviate the need for unnecessary x-rays. Although these rules have been determined to be very sensitive, they lack the specificity necessary to make them practically useful for a condition in which a misdiagnosis could result in a significant disability. Our study objective was to determine if the addition of a bedside ultrasound (US) to the evaluation process could be used to significantly reduce the number of negative x-rays in OFAR positive patients...

STUDY DESIGN: Controlled laboratory study. BACKGROUND: Deficits in light touch have recently been identified on the plantar surface of the foot in those with chronic ankle instability (CAI) but not in uninjured controls. It is unknown whether copers display similar deficits. Similarly, cognitive loading has been shown to impact postural control in different populations, but it is unclear how it may impact sensory perception. OBJECTIVES: To evaluate the difference in cutaneous sensation thresholds at rest and under cognitive loading, using Semmes-Weinstein monofilaments (SWMs), among uninjured controls, copers, and those with CAI...

The purpose of this study was to compare in-vivo kinematic angular excursions of individual metatarsal segments and a unified forefoot segment in people with Diabetes Mellitus and peripheral neuropathy (DMPN) without deformity or ulceration to a healthy matched control group. Thirty subjects were recruited. A five- segment foot model (1st, 3rd, and 5th metatarsals, calcaneus, tibia) was used to examine relative 3D angular excursions during the terminal stance phase of walking. Student t-tests were used to assess group differences in kinematics...

OBJECTIVE: To investigate the reliability of a simple, efficient technique for measuring bone mineral density (BMD) in the metatarsals using dual-energy X-ray absorptiometry (DXA). MATERIALS AND METHODS: BMD of the right foot of 32 trained male distance runners was measured using a DXA scanner with the foot in the plantar position. Separate regions of interest (ROI) were used to assess the BMD of each metatarsal shaft (1st-5th) for each participant. ROI analysis was repeated by the same investigator to determine within-scan intra-rater reliability and by a different investigator to determine within-scan inter-rater reliability...

The purpose of this paper was to systematically assess the effect of Oxford Foot Model (OFM) marker misplacement on hindfoot relative to tibia, and forefoot relative to hindfoot kinematic calculations during the stance phase of gait. Marker trajectories were recorded with an 8-camera motion analysis system (Vicon Motion Systems Ltd., UK) and ground reaction forces were recorded from three force platforms (AMTI, USA). A custom built marker cluster consisting of 4 markers in a square arrangement (diagonal distance 2 cm) was used to assess the effect of marker misplacement in the superior, inferior, anterior and posterior direction for the sustentaculum tali (STL), the proximal 1st metatarsal (P1M), distal 5th metatarsal (D5M), proximal 5th metatarsal (P5M) and lateral calcaneus (LCA) markers...

[Purpose] The purpose of this study was to investigate the effects of the ankle angle of an ankle foot orthosis (AFO) on foot pressure during the gait in healthy adults. [Subjects] Sixteen healthy males with neither orthopedic nor neurological problems participated in this study. [Methods] Subjects walked on a walkway at a self-selected pace with an AFO set at four different ankle angles (-5°, 0°, 5°, and 10°). Foot pressure was measured randomly according to the ankle angle of the AFO using an F-scan system...

Distal arthrogryposis (DA) encompasses a heterogeneous group of hereditary disorders with multiple congenital contractures predominant in the distal extremities. A total of 10 subtypes are proposed based on the pattern of contractures and association with extraarticular symptoms. DA5 is defined as a subtype with ptosis/oculomotor limitation. However, affected individuals have a variety of non-ocular features as well. We report on a two-generation family, including four affected individuals who all had congenital contractures of the distal joints, ptosis, restricted ocular movements, distinct facial appearance with deep-set eyes, and shortening of the 1st and 5th toes...

INTRODUCTION: Metatarsal coalition is an extremely rare condition. We report the second documented case of 4th and 5th distal metatarsal coalition in the literature. PRESENTATION OF CASE: An eight-year-old girl was referred to an orthopaedic clinic with a four-month history of forefoot pain and swelling on the plantar aspect of the right little toe. Radiograph and clinical examination confirmed distal metatarsal coalition between the 4th and 5th metatarsals. Following a period of conservative treatment, excision was eventually performed due to worsening symptoms...

The peroneocuboid joint, between the peroneus longus tendon and the cuboid bone, has not been anatomically well-defined and no embryological study has been published. Furthermore, the ossification of the os peroneum (a sesamoid inside the peroneus longus tendon) and its associated pathology has been considered to be generated by orthostatic and/or mechanical loads. A light microscopy analysis of serially sectioned human embryonic and fetal feet, the analysis of human adult feet by means of standard macroscopic dissection, X-ray and histological techniques have been carried out...

BACKGROUND: Chronic recurrent multifocal osteomyelitis is a form of non-bacterial osteomyelitis which occurs primarily in childhood. In some cases painful bone swelling occurs. After a malignancy has been ruled out, antibiotic therapy is often started to treat the osteomyelitis. The course of this benign disease is self-limiting and is not positively affected by the antibiotic therapy. CASE PRESENTATION: A 14-year-old German girl from South Africa came to the surgery with painful swelling in the right clavicle...

REVIEW
Matthew Solan, Mark Davies
Metatarsal fractures are those most frequently encountered in the foot. More than half of these are of the 5th metatarsal. The incidence is increasing, along with the activity levels of the general population. Fractures of the 5th metatarsal require careful evaluation and classification to ensure selection of the optimum treatment plan. Distal fractures rarely require fixation, even when displacement is wide. Cases of established nonunion or refracture require fixation.
