BACKGROUND: Mueller-Weiss disease is a rarely diagnosed deformity where the navicular bone undergoes spontaneous osteonecrosis in adults. Until now, there is no widely accepted operative treatment for this unusual disease. We aimed to compare clinical and radiological outcomes between the open triple fusion and talonavicular-cuneiform arthrodesis for Mueller-Weiss disease of stage 4. METHODS: During the period from February 2012 to June 2016, 10 patients (11 feet) suffering from Mueller-Weiss disease of stage 4 were treated by the same senior surgeon...

Tarsometatarsal (TMT) arthritis is characterized by instability and pain in the foot. The commonest cause is post-traumatic arthritis. A Lisfranc injury involves the articulation between the medial cuneiform and the base of the second metatarsal, which is considered a keystone to midfoot integrity. Neglected or undertreated injury to the Lisfranc joint complex leads to secondary arthritis and significant disability. We present a case of a young male patient with a two-year-old neglected Lisfranc joint injury and secondary osteoarthritis of the first, second, and fourth TMT joints, which we treated surgically with arthrodesis using screws, with a good functional outcome on final follow-up...

The Lisfranc fracture-dislocation of the foot is uncommon and diagnosis is often missed. The Lisfranc joint involves the articulation between medial cuneiform and base of the second metatarsal and is considered a keystone to structural integrity to the midfoot. The articulation has a stabilization effect on longitudinal and transverse arches of the foot. A neglected or untreated injury to the Lisfranc joint can lead to secondary arthritis and significant morbidity and disability. We present a case of a neglected Lisfranc fracture-dislocation in a 28-year-old female patient who presented 3 months after injury...

Scedosporium apiospermum is frequently found as a saprophyte in soil, sewage and contaminated water. Its manifestations in immunocompetent patients are usually localised and in immunodeficient patients, it causes invasive systemic diseases. We are reporting the case of a 40-year-old male, who presented with pain, oedema and multiple discharging sinuses over the lateral aspect of the left foot with history of thorn prick. On examination, there were multiple active sinuses with tenderness and local rise in temperature...

We describe a rare case of simultaneous and spontaneous osteonecrosis affecting bilateral navicular and talar bones in a young male. On both sides, there was associated symptomatic talonavicular and naviculocuneiform arthritis. The more symptomatic left foot was managed successfully by talonavicular-cuneiform (TNC) arthrodesis and core decompression of talar body. A probable cause of this rare disorder was most likely due to a developmental anomaly in the preaxial ray of the foot. As no literature is currently available for this rare condition, our case report is intended to provide a referral point for future studies in the early diagnosis and management of this condition...

Kevin Renner, Jeffrey E McAlister, Melissa M Galli, Christopher F Hyer
The naviculocuneiform articulation is composed of the navicular proximally and the 3 cuneiforms distally. It is not uncommon to perform surgical interventions at this joint for multiple pathologic foot etiologies. To date, no detailed anatomic measurement is available for each cuneiform articulation on the navicular. The purpose of the present study was to present an anatomic description of this complex joint to aid in better surgical understanding and improve surgical outcomes. Ten fresh, frozen, and thawed below-the-knee cadaveric specimens were used for anatomic dissection of the navicular and associated cuneiforms...

The mesencephalic locomotor region (MLR) is a highly preserved brainstem structure in vertebrates. The MLR performs a crucial role in locomotion but also controls various other functions such as sleep, attention, and even emotion. The MLR comprises the pedunculopontine (PPN) and cuneiform nuclei (CuN) but their specific roles are still unknown in primates. Here, we sought to characterise the inputs and outputs of the PPN and CuN to and from the basal ganglia, thalamus, amygdala and cortex, with a specific interest in identifying functional anatomical territories...

The tibialis anterior tendon bursa is located between the tibialis anterior tendon and the medial cuneiform bone and close to the tendon insertion. Bursitis can occur as a result of excessive local friction, infection, arthritides, or direct trauma. Endoscopic resection of the bursa is indicated in case of symptomatic bursitis that is not responding to conservative treatment or infection is suspected. It is contraindicated if there is skin infection at the portal sites. The purpose of this technical note is to describe a minimally invasive approach of endoscopic resection of the tibialis anterior tendon bursa through anterior tibial tendoscopy...

PURPOSE: Tibialis anterior tendon transfers (TATT) are commonly performed in young children following Ponseti casting for clubfeet. The classic TATT involves advancing the tendon through a hole drilled in the ossified cuneiform. The aim of this study was to determine if tendons transferred through unossified bones have untoward effects on subsequent bone development. METHOD: Twenty-five piglets underwent one of five surgical procedures. An 18-gauge needle was then used to place a tunnel through the bony or cartilaginous portion of the calcaneus (through direct visualization) and isolated slips of the flexor digitorum superficialis (FDS) were placed through the tunnels, as determined by surgical procedure...

PURPOSE: Early stage adult acquired flatfoot deformity (AAFD) is traditionally treated with osteotomy and tendon transfer. Despite a high success rate, the long recovery time and associated morbidity are not sufficient. This study aims to evaluate the functional and radiological outcomes following the use of the arthroereisis screw with tendoscopic delivered PRP for early stage AAFD. METHODS: Patients with stage IIa AAFD who underwent the use of the arthroereisis screw with tendoscopic delivered PRP with a minimum follow-up time of 24 months were retrospectively evaluated...

: Common surgical treatment of first tarsal-metatarsal arthritis is by first metatarsocuneiform joint arthrodesis. While crossed-screw and locking plate fixation are the most widely used methods, a novel construct was designed to alleviate soft tissue irritation while still providing stable fixation. Using anatomic first metatarsal and medial cuneiform composites, we compared 3 arthrodesis implants (crossed-screw, dorsal locking plate, and IO Fix) under 2 cyclic bending loading scenarios (cantilever and 4-point bending)...

OBJECTIVES: We aimed to study the categorizations "Overdrive" and "Edge" from the pedagogical method Complete Vocal Technique as refiners of the often ill-defined concept of "belting" by means of audio perception, laryngostroboscopic imaging, acoustics, long-term average spectrum (LTAS), and electroglottography (EGG). STUDY DESIGN: This is a case-control study. METHODS: Twenty singers were recorded singing sustained vowels in a "belting" quality refined by audio perception as "Overdrive" and "Edge...

: Arthrodesis of the first metatarsal cuneiform joint, or Lapidus procedure, is a widely accepted treatment for hallux valgus. Recent studies have focused on comparing various constructs for this procedure both in the laboratory and clinical settings. The current study compared in a cadaveric model the strength of 2 constructs. The first construct utilized a medially applied low-profile locking plate and an interfragmentary screw directed from plantar-distal to dorsal-proximal. The second construct consisted of a plantarly applied plate with a compression screw placed through the plate from plantar-distal to dorsal-proximal...

A 61-year-old man with a history of squamous cell carcinoma of the lung presented with a progressive left foot pain for 7 months. Bone scan was acquired to evaluate possible metastasis, which showed abnormal accumulation of Tc-MDP in the left foot, which was seen in the medial cuneiform bone on SPECT/CT images. Histopathological examination from biopsy specimen confirmed cuneiform bone metastasis from lung squamous carcinoma.

Tuberculous osteomyelitis is rare and usually involves the vertebrae but is seldom found in the foot. The uncommon site and ability to mimic other disorders clinically and radiographically leads to diagnostic and therapeutic delays. We report a case of a 40-year-old man who initially presented to his podiatrist with intermittent pain and swelling of his right ankle and foot that lasted for a year. He also started to exhibit significant weight loss and unexplained fevers and was subsequently hospitalized for cellulitis of his right foot...

The effects of various modes of low-intensity laser exposure on the sera of healthy subjects and patients are studied. It is shown by the cuneiform dehydration method that the serum structure is liable to change in response to certain modes of low-intensity laser exposure. The structure of patients' sera is more sensitive to low-intensity laser exposure.

Osteoarticular TB around the tarsal navicular is a chronic, uncommon condition affecting the midfoot, which causes significant morbidity to the patient. Tuberculosis around the tarsal navicular is rarely described in the literature. A series of three cases - two involving the talo-navicular joint and one involving the naviculo-cuneiform joint is described. Biopsy was used in all the cases for achieving diagnosis. All patients had good to fair outcome following medical management with anti-tubercular therapy...
