Background: Cosmetic dissatisfaction, pain, and chronic discharge may present months till years after enucleation in patients operated because of retinoblastoma. If noninvasive treatment modalities are insufficient, socket reconstruction can be considered. In this study, we discuss the results of dermis-fat exchange to treat these problems.
Method: Four patients with late onset post enucleation socket problems with a request for treatment were included in this prospective study. Socket inspection was documented and pictures at baseline and at a follow-up of at least 6 months were taken. To quantify the problem 'pain', a VAS score at baseline and at follow up was used. For the problem 'cosmetic dissatisfaction' standardized questionnaires were used.
Results: Two patients were included because of cosmetic dissatisfaction; one was included with chronic pain and one with chronic discharge. Reconstruction of the socket using autologous dermis-fat insertion was done in all four. In one of them, severe shrinking of the fat developed. This patient was treated with additional injectable fillers. Both of them, ultimately, had satisfactory results. Autologous fat transplantation also solved the problem of chronic discharge and pain in the two other patients.
Conclusion: Socket reconstruction by autologous dermis-fat exchange may solve different post enucleation socket problems. However, shrinking of the transplanted fat may occur and require additional procedures.

To solve the problems of insufficient stiffness and poor integrity of traditional F-type socket joints, steel screw connections are set along the longitudinal direction between rectangular pipe jacking joints. However, the mechanical properties of F-type socket joints with steel screw connections have not been fully investigated, and the influence of the coefficient of subgrade reaction has not been considered. In this work, through model tests and numerical simulations of F-type socket joints with steel screws under different coefficients of subgrade reaction, the influence of steel screws on the deformation and damage characteristics of F-type socket joints is discussed, and the bending mechanical response of F-type socket joints under different coefficients of subgrade reaction is analyzed.

This paper creates 3D models of Kitchon Root Controlled Auxiliary Archwire (Kitchon-RCAA) with different material properties and assembles them onto the main archwire equipped with brackets. By setting different loading methods and conducting Finite Element Analysis (FEA), the range of Orthodontic Torque/Support Force (OT/SF) values can be obtained. From the obtained values, it can be seen that changes in material properties have a significant impact on the mechanical properties of Kitchon-RCAA.

Background: Prosthetic socket is a key component of the prosthesis for clinical application; its performance directly affects the adaptation of the residual limb to the prosthetic socket. There are long-term and short-term volume fluctuation of the residual limb. The volume fluctuation of the residual limb will lead to the pressure mismatch at the interface of the residual limb and the prosthetic socket, which will cause a series of skin and fit problems.

The limb amputations caused due to emergent incidents of trauma injuries and vascular diseases currently represent crucial global problems. The patients/amputees with limb amputation who lost the residual limb (knee-ankle foot system) must depend on the prosthetic limb. Prosthetic clinicians and technicians have attempted to develop optimal limb prosthetics that will enhance the ability and functional elements of the patients/users.
