During the course of a biodiversity survey of the endoparasitic aseptate gregarines in the Malda district of West Bengal, India, seminal vesicles of the earthworm, Eutyphoeus kherai, Julka 1978 were found to be infested with a new species, Monocystis julkae sp.nov., of the genus, Monocystis Stein (Arch Anat Phys Med 181-223, 1848). The trophozoite is elongated but slightly constricted posteriorly. A tail like protrusion appears in the posterior end. Anterior end is rather wider than the posterior one. The whole body size of the trophozoite measures 102...

INTRODUCTION: The accessory navicular (AN) is an accessory ossicle anatomically located on the medial side of the foot, proximal to the navicular and continuous with the tibialis posterior tendon. It is occasionally a source of pain and local tenderness. Knowledge of the AN and its morphological variations can help identify the source of a patient's symptoms and prevent misinterpreting them as fractures. MATERIALS AND METHODS: Foot radiographs from 1240 patients who presented in two centers with chronic foot pain, or persistent pain developed after trauma, were retrospectively reviewed to determine the incidence and variations of the AN in relation to gender...

Reports of Legg-Calvé-Perthes disease (LCPD) in the paleopathological literature are rare. Here, the authors present a probable case of LCPD, which presents as abnormal morphology of the proximal femur. The condition was observed in an individual of the Warring States period in Shaanxi Province, China, and the morphology involves a "mushroom head" deformity of the proximal right femur and an enlarged acetabulum, along with a contralateral tibia, talus, and navicular that are enlarged and demonstrate periosteal new bone formation...

BACKGROUND: A talus control foot orthosis (TCFO) combines an inverted rigid foot orthosis (RFO) with a broad upright portion that rises well above the navicular to cover and protect the talonavicular joint. We sought to identify the therapeutic effect of TCFOs in children with flexible flatfoot. METHODS: Flexible flatfoot was diagnosed in 40 children when either of the feet had greater than 4° valgus of resting calcaneal stance position (RCSP) angle and one of the radiographic indicators was greater than 30° in anteroposterior talocalcaneal angles, 45° in lateral talocalcaneal angles, and 4° in lateral talometatarsal angles and less than 10° of calcaneal pitch in barefoot radiographs...

BACKGROUND: The accurate and reliable measurement of foot bone density is challenging and there is currently no gold standard technique. Such measurement is particularly valuable in populations at risk of foot bone pathology such as in those with long term diabetes. With research and development, computed tomography may prove to be a useful tool for this assessment. The aim of this study was to establish the reliability of a novel method of foot bone density measurement in people with diabetes using computed tomography...

Favorable results have been reported for tibialis posterior tendon transfers, which can effectively restore the dorsiflexion of the ankle and normal heel-to-toe gait. However, the commonly used methods for anchoring the transplanted tendon have some drawbacks. Therefore, we developed a new tendon-anchoring method to improve fixation of the transferred tendon and reduce the related complications. The new method entails tying the anchoring suture to the navicular bone instead of the button on the plantar foot to avoid wound complications...

Stephen Joseph Shymon, Thomas Gregory Harris
We describe a low-cost (instrument cost) technique for joint distraction using 2 Kirschner wires and a toothed lamina spreader in lieu of a Hintermann distractor. The described technique allows for temporary intra-articular distraction and visualization and preservation of the articular surface with extra-articular instrumentation. The technique can also allow for closed reduction and percutaneous treatment in cases of soft tissue compromise. Additionally, the technique uses common orthopedic surgical instruments, leading to a minimal learning curve for novice surgeons...

Tun Hing Lui
A too-long anterior process (TLAP) of the calcaneus is an elongated anteromedial process of the calcaneus impinging the navicular or the talar head. TLAP can cause recurrent ankle sprain, peroneal muscle spasm, or persistent tarsal pain in adolescents. Arthroscopic resection is indicated if the symptoms do not respond to conservative treatment. It has the advantage of assessment of completeness of bone resection and treatment of associated lesions of the adjacent joints. The purpose of this technical note is to report an arthroscopic approach of the resection of the TLAP with the lateral midtarsal portal as the viewing portal...

BACKGROUND: Arthrodesis of the medial column (navicular, cuneiform I and metatarsal I) is performed for reasons such as Charcot arthropathy, arthritis, posttraumatic reconstruction or severe pes planus. However, the complication rate is still high and mainly resulting from inadequate fixation. Special plates, designed for medial column arthrodesis, seem to offer potential to reduce the complication rate. The aim of this study was to investigate biomechanically plantar and dorsomedial fusion of the medial column using two new plating systems...

Julien Olive, Marine Videau
OBJECTIVES: Macroscopic studies have suggested a link between distal border synovial invaginations of the navicular bone and the distal interphalangeal joint. However, many practitioners consider that these invaginations are directly and solely related to navicular disease. The objective was to investigate the communication pattern of these synovial invaginations with the synovial compartments of the distal interphalangeal joint and the navicular bursa, using minimally invasive imaging techniques...

BACKGROUND: The aim was to develop statistical shape models of the main human tarsal bones that would result in novel representations of cuboid, navicular and talus. METHODS: Fifteen right and 15 left retrospectively collected computed tomography data sets from male individuals, aged from 17 to 63 years, with no known foot pathology were collected. Data were gathered from 30 different subjects. A process of model building includes image segmentation, unifying feature position, mathematical shape description and obtaining statistical shape geometry...

The accessory navicular bone is one of the most common accessory ossicles of the foot. Fewer than 1% of accessory navicular bones are symptomatic, and most of these are type II accessory navicular bones. A separation of the synchondrosis is considered one of the main causes of pain. After an injury to the synchondrosis has resulted in a chondro-osseous disruption, the combined forces of tension and shear from the posterior tibial tendon and the foot aggravate the injury and prevent it from healing. Fusion of the synchondrosis is a logical surgical treatment option if the pain is recalcitrant to conservative measures...

Simple bone cyst is a common tumorlike lesion of the bone and can involve the bones of the foot. It is usually asymptomatic but can also present with pain or pathologic fracture. The purpose of this technical note is to describe the uni-osseous portal approach of endoscopic curettage and bone grafting of simple bone cyst of the navicular bone. The single-portal approach reduces the risk of iatrogenic fracture of the navicular bone. This is indicated for painful bone cyst of the navicular bone resistant to conservative treatment...

BACKGROUND: Some physicians report that patients with hallux valgus have hypermobility at the tarsometatarsal (TMT) joint of the first ray and 3-dimensional (3-D) deformity. With use of non-weight-bearing and weight-bearing computed tomography (CT), we evaluated the 3-D mobility of each joint of the first ray in feet with hallux valgus compared with normal feet. METHODS: Ten feet of 10 patients with hallux valgus and 10 feet of 10 healthy volunteers with no foot disorders were examined...

OBJECTIVE: Wrist joint space narrowing is a main radiographic outcome of rheumatoid arthritis (RA). Yet, automatic radiographic wrist joint space width (JSW) quantification for RA patients has not been widely investigated. The aim of this paper is to present an automatic method to quantify the JSW of three wrist joints that are least affected by bone overlapping and are frequently involved in RA. These joints are located around the scaphoid bone, viz. the multangular-navicular, capitate-navicular-lunate, and radiocarpal joints...

BACKGROUND: Navicular disease in the horse often requires injection of the navicular bursa. We have developed an ultrasound-guided, lateral needle approach to navicular bursocentesis, which avoids penetration of the deep digital flexor tendon (DDFT) and the need for radiographic control. OBJECTIVES: To describe and evaluate the feasibility and efficacy of an ultrasound-guided, lateral bursocentesis technique. STUDY DESIGN: Cadaveric and in vivo experiments...
