Fifth metatarsal

Christopher R Hood, Stephanie Eldridge, Matthew Tran, Jason R Miller
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...

Misalignment of the talar neck after surgical repair can redistribute the load among the posterior, middle, and anterior facets of the subtalar joints, which can change the joint biomechanics, cause arthritis, and impair function. However, we found no studies analyzing the plantar pressures after treatment of talus neck fracture. We determined the dynamic plantar pedobarographic and radiographic characteristics and ankle range of motion, function, and pain among patients after surgical repair of talar neck fractures...

PURPOSE: A 4-2-1 stepping algorithm reliably captures light touch thresholds but has not been used to assess two-point discrimination (TPD) thresholds. Therefore, the purpose of this investigation was to determine the intra- and inter-rater reliability of a 4-2-1 stepping algorithm at determining TPD thresholds. MATERIALS AND METHODS: Fifteen healthy, physically active young adults were assessed twice over a 1-week period using digital calipers and a 4-2-1 stepping algorithm...

Nonhealing wounds along the fifth metatarsal associated with neuropathy and bone deformity frequently become complicated with osteomyelitis. Our surgical technique for complete fifth ray amputation with peroneal tendon transfer has been previously published. The present study evaluated the outcomes regarding success with initial healing and intermediate-term limb survival after this procedure, which is intended to resolve infection, remove bone deformity, heal and prevent recurrence of lateral column wounds, and maintain functional stability of the foot...

Sensory impairments caused by neurological or physical disorders hamper kinesthesia, making rehabilitation difficult. In order to overcome this problem, we proposed and developed a novel biofeedback prosthesis called Auditory Foot for transforming sensory modalities, in which the sensor prosthesis transforms plantar sensations to auditory feedback signals. This study investigated the short-term effect of the auditory feedback prosthesis on walking in stroke patients with hemiparesis. To evaluate the effect, we compared four conditions of auditory feedback from plantar sensors at the heel and fifth metatarsal...

INTRODUCTION: It is unknown whether footwear has a beneficial or deleterious effect on cutaneous sensitivity. We aim to test a preliminary model of footwear and its effect on tactile perception among groups of controls, copers, and chronic ankle instability (CAI) participants. METHODS: Light-touch thresholds were obtained for 45 participants (age: 20.2 ± 2.8 years; height:167.6 ± 9.8 cm; mass:66.3 ± 14.7 kg) using Semmes-Weinstein monofilaments at the head of the first metatarsal (1MT), base of the fifth metatarsal(5MT), and calcaneus(CAL)...

BACKGROUND: McCune Albright syndrome is rare with an estimated prevalence of 1 in 100,000 to 1 in 1,000,000 persons. The classical clinical triad consists of fibrous dysplasia of the bone, café-au-lait skin spots and precocious puberty. However, in rare cases, there may be primary hypogonadism and amenorrhea. CASE PRESENTATION: An eighteen-year-old female presented with amenorrhea. She had a short stature, round face, thick neck, and short fourth metacarpals and metatarsals...

This study aimed to assess the effects of running-induced fatigue on plantar pressure parameters in novice runners with low and high medial longitudinal arch. Plantar pressure data from 42 novice runners (21 with high, and 21 with low arch) were collected before and after running-induced fatigue protocol during running at 3.3m/s along the Footscan(®) platform. Peak plantar pressure, peak force and force-time integral (impulse) were measured in ten anatomical zones. Relative time for foot roll-over phases and medio-lateral force ratio were calculated before and after the fatigue protocol...

BACKGROUND: Patients with peripheral neuropathy and pressure under a relatively plantar deviated metatarsal head frequently develop plantar foot ulcers. When conservative management with orthotics and shoes does not cure the ulcer, surgical metatarsal osteotomy may be indicated to relieve the pressure and enable the ulcer to heal. The purpose of this study is to evaluate the use of a mini-invasive floating metatarsal osteotomy in treating recalcitrant ulcers or recurrent ulcers plantar to the metatarsal heads in patients with diabetes mellitus (DM) related neuropathy...

The aim of this study is to characterize bone erosions in metatarsal heads (MTH) in rheumatoid arthritis (RA) and gout by grayscale ultrasound. In a descriptive, cross-sectional study, we evaluated 40 patients with RA and 40 with gout, both diagnosed according to the American College of Rheumatology/European League Against Rheumatism criteria, respectively. All patients had bone erosion demonstrated by ultrasound, which was used, following OMERACT criteria, to describe the shape, size, number, border definition, overhanging margin, topography (intra- or extra-articular), and distribution (over dorsal, medial, lateral, or plantar aspect) of the lesions in the MTH...

Subtle injuries of the Lisfranc joint complex are uncommon and difficult to diagnose clinically and thus are easily missed even by experienced orthopedic doctors. Misdiagnosed injuries can lead to chronic disability until eventual fusion surgery. We describe 10 cases diagnosed with subtle injury of the Lisfranc joint that were treated with combined innovative portal arthroscopy and fluoroscopy-assisted reduction and percutaneous screw fixation in an interfragmentary fashion. The distance between the first and second metatarsals (the Lisfranc distance) and that between the medial cuneiform and fifth metatarsal base (foot arch height) was measured before and after surgery...

BACKGROUND: Detailed investigation of the vasculature of the lateral aspect of the foot has rarely been presented. However, harvesting the flap in this area to cover defects of the foot and hand is highly important. Repair of soft-tissue defects at the forefoot remains a challenge in reconstructive surgery. This study explores the characteristics of the distal-based lateral dorsal cutaneous neuro-lateral plantar venofasciocutaneous flap pedicled with the lateral plantar artery perforator of the fifth metatarsal bone to establish a repair procedure for ulcers or defects in the forefoot region...

AIMS: The purpose of this study was to compare symptomatic treatment of a fracture of the base of the fifth metatarsal with immobilisation in a cast. Our null hypothesis was that immobilisation gave better patient reported outcome measures (PROMs). The alternative hypothesis was that symptomatic treatment was not inferior. PATIENTS AND METHODS: A total of 60 patients were randomised to receive four weeks of treatment, 36 in a double elasticated bandage (symptomatic treatment group) and 24 in a below-knee walking cast (immobilisation group)...

INTRODUCTION: Diminished cutaneous detection thresholds have been identified in patients with multiple orthopaedic conditions, and these phenomena may occur in post-anterior cruciate ligament reconstructed (ACLR) patients. The purpose of this study was to determine if differences in lower extremity cutaneous detection thresholds exist in post-ACLR patients when compared to healthy controls. METHODS: Fifteen individuals who were post-ACLR and 15 individuals who had no history of knee injury participated...

Cornelia de Lange syndrome (CdLS) is a well-described multisystem developmental disorder characterized by dysmorphic facial features, growth and behavioral deficits, and cardiac, gastrointestinal, and limb anomalies. The limb defects seen in CdLS can be mild, with small feet or hands only, or can be severe, with variable deficiency defects involving primarily the ulnar structures and ranging from mild hypoplasia of the fifth digit to complete absence of the forearm. Interestingly, the upper limbs are typically much more involved than the lower extremities that generally manifest with small feet and 2-3 syndactyly of the toes and shortened fourth metatarsal...

Since it was first described by Song in 1982, then by Katsaros in 1984, the lateral arm flap has become a workhorse technique for upper limb reconstruction. Herein we describe a clinical case of complex foot defect and bring up the possibility of using a composite neuromusculo-fasciocutaneous lateral arm/triceps free flap for its reconstruction. A 19-year-old male nonsmoker suffered ballistic trauma to his right foot with open multifragment Gustilo-IIIb fractures of the first to fifth metatarsal bones. Two weeks after debridement and V...

In the present report, a new radiographic classification for distal shaft fractures of the fifth metatarsal is presented. The classification system is based on a review of 79 spiral oblique fractures of the distal shaft of the fifth metatarsal. The sample was grouped into "grades" of deformity according to the configuration of the fracture and the amount of displacement observed for each injury. Four distinct fracture configurations emerged as a result of our radiographic analysis, and these were categorized as grades I, IIA, IIB, and III...

Before the report of English surgeon Robert Jones, who sustained a fracture to his fifth metatarsal while dancing around a tent pole, metatarsal fractures were thought to be the result of direct trauma to the foot. The mechanism of metatarsal fractures, in particular, those involving the fifth metatarsal, is now well understood. Patients with an adducted alignment of their forefoot can overload the fifth metatarsal base, putting them at an increased risk of fractures of this bone. Studies have reported that 2 distinct types of proximal diaphyseal or junctional fractures of the fifth metatarsal occur: the acute proximal diaphyseal or transverse proximal diaphyseal fracture and the proximal diaphyseal stress fracture...
