REVIEW
Jessica A Cottrell, Jessica Cardenas Turner, Treena Livingston Arinzeh, J Patrick O'Connor
This review describes the normal healing process for bone, ligaments, and tendons, including primary and secondary healing as well as bone-to-bone fusion. It depicts the important mediators and cell types involved in the inflammatory, reparative, and remodeling stages of each healing process. It also describes the main challenges for clinicians when trying to repair bone, ligaments, and tendons with a specific emphasis on Charcot neuropathy, fifth metatarsal fractures, arthrodesis, and tendon sheath and adhesions...

BACKGROUND: Ankle inversion injuries are one of the most common and burdensome injuries in athletic populations. Research that prospectively identifies characteristics associated with this injury is lacking. This prospective study compared baseline anthropometric and biomechanical gait characteristics of military recruits who sustained an ankle inversion injury during training, with those who remained injury-free. METHODS: Bilateral plantar pressure and three-dimensional lower limb kinematics were recorded in 1065 male, injury-free military recruits, during barefoot running...

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...

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...

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...
