A shoe with belts according to the present invention comprising an upper, a sole S that has a first and second roll-up portions S11, S10 rolling upwards along side faces of a foot, and first and second belts 51, 52. The first belt 51 is fixed to the first roll-up portion S11 at a first joined portion 58 on the medial side of the foot. The second belt 52 is fixed to the second roll-up portion S10 at a second joined portion 59 on the lateral side of the foot. The pair of belts 51, 52 cross each other at a position approximately above the navicular bone 91. The first belt 51 can be arranged in a tensioned state along a path extending from the medial side of the foot to the vicinity of an ankle on the lateral side of the foot through the crossing position 57. The second belt 52 can be arranged in a tensioned state along a path extending from the lateral side to the vicinity of the ankle on the medial side of the foot through the crossing position 57.

A device, method, and system for treatment or fixation of a fractured, damaged, or deteriorating bone or bones in a mid-foot region. The device comprising an implant with both proximal and distal fastener holes, along with fastener slots in a central elongated body, for securing the implant to the appropriate osseous cortical structures of the foot. The method for treatment or fixation of fractured, damaged, or deteriorating bones in the medial column of the foot with use of a device such as an intramedullary nail that attaches to either the talus or first metatarsal bones to secure the medial cuneiform and navicular bones in place.

A talonavicular joint prosthesis (1) adapted to replace the natural talonavicular joint that exists between a patient's talus and navicular bones, after appropriate surgical preparation of the joint-related portions of these bones so as to create a new joint space to accommodate this prosthesis, includes talar (2) and navicular (4) components. Each of these have inner (8, 28) and outer (6, 26) surfaces whose average separate distance is defined as the component's average thickness. These components inner (8, 28) surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each component's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection in the creation of the new prosthesis-accommodating, joint space.

The invention relates to a metacarpophalangeal joint stiffness drafting device. The problem that an existing support cannot effectively control the direction of force, and consequently treatment needs cannot be met is mainly solved. The device comprises a palmaris supporting clamping plate, a binding part, a finger traction assembly and a tension guide part, the finger traction assembly comprises a finger sleeve, a traction line and a clamping part, the tension guide part is an adjusting plate, the adjusting plate is fixed to the palmaris supporting clamping plate and extends downwards, guide holes sequentially distributed in the extending direction of the adjusting plate are formed in the adjusting plate, and one guide hole corresponds to one force direction. The finger sleeve is used for being arranged on the finger in a sleeving mode, one end of the traction line is connected with the finger sleeve, the other end of the traction line penetrates through the corresponding guide hole to be connected with the clamping part, and the clamping part is fixed to the adjusting plate in a clamped mode. According to the metacarpophalangeal joint stiffness drafting device, the direction of force can be effectively controlled to meet treatment needs, the direction of drafting force of all metacarpophalangeal joints is perpendicular to the proximal phalanx and points to the navicular bone, the aim of treatment is effectively achieved, and the advantages of being simple in manufacturing process, low in treatment cost and good in treatment effect are achieved.

The invention discloses an external fixation bracket for minimally invasive percutaneous fixation of a carpal navicular bone, which relates to the field of medical devices and includes a connecting frame, two limb fixing frames, two fixing frame position adjustment mechanisms, an aiming sleeve and an aiming sleeve fixing The two limb fixing frames are arranged at intervals and correspond to the position adjustment mechanisms of the two fixing frames; the limb fixing frame includes a screw rod, two sliding rods, two sliding blocks and two fixed bone calipers. The two sliding rods are arranged in parallel and spaced apart. The two ends of the screw rod are respectively provided with threads in opposite directions. The fixed bone calipers are connected with the two sliding blocks in one-to-one correspondence, and one end of the screw rod is rotatably connected with the position adjusting mechanism of the fixing frame. The external fixation bracket for the minimally invasive percutaneous fixation of the carpal navicular bone of the present invention has the advantages of convenient operation, high operation efficiency, high accuracy and high safety.

The present invention provides a pad capable of effectively curbing fall of a plantar arch. A pad in accordance with the present embodiment, for supporting the plantar arch of a sole of a foot, is provided in a supporter, made of a stretch cloth, including a plantar part and an instep part, which is connected to the plantar part. The pad is located in the plantar part and has an apex, which is provided at a position corresponding to an area in the sole of the foot which area corresponds to the navicular bone of the foot.
