The present invention provides polymers for use in preventing damage to the membranes of cells in fat grafts. Mixing of a triblock copolymer such as poloxymer P188 with adipocytes or adipose tissue to be transplanted into a subject is thought to stabilize the membranes of the cells leading to more successful fat transplantation in soft tissue reconstruction or augmentation. Such methods may also be used in the transplantation of adult stem cells or other cells derived from fat tissue. Other agents such as lipoic acid may also be added to the polymer / cell compositions for cell transplantation.

Disclosed herein are patient-specific craniofacial implants structured for filling bone voids in the cranium as well as for simultaneously providing soft tissue reconstruction and / or augmentation for improved aesthetic symmetry and appearance. Pterional voids or defects generally result from a chromic skull deformity along with a compromised temporalis muscle or soft tissue distortion from previous surgery. When muscle atrophy occurs in the pterion, temporal hollowing generally results where there would be soft tissue but for the atrophy. The patient-specific temporal implants herein are configured to have an augmented region adjacent the temporal region of the cranium in order to account for and correct any such temporal hollowing.

A biocompatible surgical scaffold made from a multi-filament silk yarn for soft tissue reconstruction. The scaffold incorporates regions of varying stretch having different physical and mechanical properties that allow contouring to the required soft tissue shape to be replaced or repaired. The porous structure allows tissue in-growth, while the mesh degrades at a rate which allows for a smooth transfer of mechanical properties to the new tissue from the silk scaffold.

An adjustable, stand-alone tensioning system requires no additional fixturing, weights, or bone surface modification, and allows a single practitioner to provide an adjustable and repeatable tension to a soft tissue graft, and to install the final fixation implant. Its design facilitates introduction of the suture component of the graft into the tensioning process by simplifying retention of the suture. An even, regulated and reproducible tension is easily achieved without requiring the practitioner to manually pull on the suture strands to maintain graft tension.

A system for generating a reconstruction of an object of interest comprises a shape model generator (1) for generating a shape model representing a shape of the object in dependence on a plurality of projections of the object, and a reconstructor (2) for reconstructing the object, based on the projections, in dependence on the shape model to obtain the reconstruction of the object. The reconstructor (2) comprises a soft-tissue reconstructor (4) for generating a reconstruction favoring soft tissue, based on the plurality of projections, and a sparse reconstructor (5) for generating a reconstruction of sparse objects, based on the plurality of projections. The reconstructor (2) comprises a clipping subsystem (3) for clipping an outside of the object from the reconstruction, based on the shape model, or the reconstructor (2) is arranged for reconstructing only an inside and / or boundary of the object as defined by the shape model.

Described herein are implants (e.g., medical textiles / biotextiles) that include stitched gripping filaments to increase gripping, and methods of forming and using them. In some configurations these apparatuses may be configured as surgical grafts that may be used for soft tissue reconstruction, regeneration, or repair.

The invention provides a hip joint torque measurement system, comprising a fixing device suitable for being fixed on a limb connected with the hip joint to be measured, a strain device fixedly connected with the fixing device, and the strain device is exerted force and passed through the When the fixation device rotates the limb, and thus the femur covered by the limb around the axis of the femur, a uniform strain can be generated, and a measuring device for determining the amount of strain of the strain device. The hip joint torque measurement system of the present invention can measure the moment of the patient's hip joint during the operation, verify the necessity of soft tissue repair of the hip joint, and determine how to perform targeted and effective repair of the patient's soft tissue according to the measurement results , reconstruct the soft tissue balance of the hip joint after surgery, and increase the stability of the hip joint, thereby improving the curative effect of total hip replacement surgery and significantly reducing the postoperative dislocation rate.
