Ocular Defect

Loss of an eye or any body part has an intimidating and crippling effect on the psychosocial well-being of the patient. Although the artificial prosthesis cannot restore the function, it can highly improve the patient’s esthetics and help them regain their psychological confidence. Literature has advocated various rehabilitation modalities including empirical use of stock shells, modifying stock eyes, custom-made ocular prostheses, ocular implants, etc. A custom-made ocular prosthesis, among all the techniques, shows improved adaptation to tissue bed, distributes uniform pressure, provides a more esthetic and precise result, and is relatively cost-effective. This case report explores a relatively comprehensive method of custom ocular prosthesis fabrication for an ocular defect with a satisfactory outcome.

Abstract Background Flexor pollicis longus (FPL) tendon rupture is a rare complication of scaphoid nonunion. Case Description A fit active 70-year-old woman ruptured her FPL when it abraded on a painless 50-year-old scaphoid nonunion. She had asymptomatic scaphoid nonunion advanced collapse (SNAC) arthritis. At surgery, the sharp mobile volar scaphoid osteophytes were excised and the volar wrist capsule was repaired. A vascularized fat flap based on a perforator of the radial artery was used to augment the volar wrist capsule repair and to create a smooth gliding surface for the FPL. The ruptured FPL tendon was reconstructed with a palmaris longus graft. Literature Review Complete rupture of the FPL tendon secondary to scaphoid nonunion is a rare complication. It can be easily misdiagnosed because the original injury may be unrecognized or forgotten. A consensus regarding the optimal surgical management has not been reached. Clinical Relevance The objective of surgery in this case was to restore FPL function and prevent a recurrent rupture. The asymptomatic SNAC arthritis was not treated. No further wrist surgery was required. The patient was asymptomatic with a functioning FPL tendon 4 years after surgery.

The loss of one eye may be due to a congenital defect, pathology or trauma requiring the surgical removal of eyeball. This causes significant physical and emotional disturbance to the patient. Psychological distress can be reduced by timely replacement with an artificial eye. This preliminary report describes the fabrication of the custom made acrylic resin ocular prosthesis (CMAROP) with a modified technique where a stock eye shell has been used to fabricate a custom ocular impression tray. Try in was done on the same day. The CMAROP achieves intimate contact with the tissue bed and creates functional and esthetically pleasing results.DOI: http://dx.doi.org/10.3126/jucms.v2i4.12068Journal of Universal College of Medical Sciences (2014) Vol.02 No.04 Issue 08Page: 41-44

Background: The absence of external ear may be due to congenital, traumatic, or surgical causes. Many case reports only describe impression techniques to record details of the defect side and the natural ear. The purpose of this case report is to explain in detail simple clinical and laboratory procedures involved in fabrication of ear prosthesis. Case Description and Methods: The use of three-part mold helps in the application of pigmented silicone in specific areas. The use of direct adhesive fixation provides the best esthetic result and if properly used the most satisfactory form of treatment. Findings and Outcomes: The patient was satisfied with the life-like appearance of the prosthesis. The use of direct adhesive fixation gave the patient a sense of security and improved his confidence. Conclusion: The technique described is economical, and additional steps of implant placement are avoided. The esthetics of the prosthesis made by hand carved clay pattern provides good details. Clinical relevance The technique describes the method of direct adhesive fixation of the prosthesis giving it a life-like appearance. The confidence of the patient is also restored.

Background: Surfing with transfemoral knee prosthesis requires flexion of the hip, knee, and ankle and balance between flexibility and stiffness of the prosthetic limb. We report on Mr D, a transfemoral amputee, who wanted to surf again. Case Description and Methods: Technical specifications were based on Mr D’s complaint. The prosthesis is salt water resistant and combines a shock absorber associated with elastic tendons to permit the knee to bend easily and to facilitate eccentric braking. Surfing was observed using videos of movements and subjective analysis of compensations. Findings and Outcomes: Mr D uses this prosthesis for surfing with good results and got back to his former level using compensations. During the takeoff, he cannot shorten his left leg. He makes a circumduction movement to put his leg in front of the board. Conclusion: This prosthesis is adapted for surfing and allows precise adjustments to surfing conditions. Clinical relevance Appropriate prosthesis design can enable return to surfing for a transfemoral amputee.

Objectives: The aim of this study is to compare the mechanical characteristics of resins for 3D printers with the acrylic resins that have been used in Dentistry, according to the post-processing method. Materials and Methods: Using an SLA 3D printer (Form 2 – Formlabs, Massachusetts, USA), samples (discs) were produced with the printer’s resins, Dental SG®, Dental LT®, Clear®, and Grey®. Samples made of thermopolimerized and auto polymerized acrylic resins were produced as well (Gold Standart parameters). The Knoop Hardness (KH) tests were performed using microdurometer HMV-2 (Shimadzu, Kyoto, Japan). Results: The results showed the Dental SG resin presented the highest KH, compared with thermopolimerized acrylic resin, the Clear and Dental LT resins KH were compared with auto polymerized acrylic resin, and the non-post cured Grey resin (not for intraoral use), as well as the Dental LT resin, showed the lowest KH. Conclusions: Considering the hardness, the printer’s resins are comparable with the acrylic resins established, when the post-processing method is thoroughly followed. The absence of material’s post-processing reduce significantly the material’s hardness. Clinical relevance: Regarding the use of 3D printing in Dentistry, the development of materials adequate for the equipment, biocompatible for intraoral uses, and compatible mechanical proprieties are essential.

Background: To overcome the challenges of rehabilitation of bilateral transfemoral amputees, we developed a novel “hip prosthesis in the sitting posture.” Case Description and Methods: A 64-year-old male bilateral transfemoral amputee was transferred for rehabilitation 4 months following a burn injury. His wounds remained unhealed for 20 months; thus, he was unable to participate in standing training with the standard prosthetic sockets. Hip prosthesis in the sitting posture has very little friction between the sockets and residual limbs, which facilitated our patient to begin standing and walking exercises. Findings and Outcomes: The patient’s refractory wounds healed 1 month after initiating exercises using hip prosthesis in the sitting posture, and he could begin rehabilitation with the standard prostheses. Discussion and Conclusion: Hip prosthesis in the sitting posture enabled a bilateral transfemoral amputee with unhealed residual limbs to stand, walk, and begin balance training. Hip prosthesis in the sitting posture is an effective temporary prosthesis to prevent disuse until wounds are healed and to continue rehabilitation with standard prostheses. Clinical relevance Hip prosthesis in the sitting posture is useful for bilateral transfemoral amputees with unhealed residual limbs after burn injuries to prevent disuse and maintain motivation for walking.

Background: The purpose of this article is to describe a technique which helps in fabrication of glove-type hollow thumb prosthesis using three-part mould technique. Case description and methods: Patient reported to the Department of Private dental clinic, Delhi, India with a chief complaint of missing partial left thumb and wanted to get it replaced. A complete clinical hand examination was carried out, which revealed a residual stump of 1 cm length. After ensuring the medical conditions to be normal, fabrication of hollow thumb prosthesis was planned using three-part mould technique. Findings and outcomes: The prosthesis delivered to the patient was highly retentive because of its glove-type retention and lighter weight; feedback from the patient regarding retention was excellent. The prosthesis was aesthetically pleasing because of its excellent colour matching with the skin, and each and every part of the prosthesis could be colour customized because of easy retrieval of the third part of the mould, as well. Conclusion: A technique of hollow thumb prosthesis has been described in this article which helps in reduction in weight, easy packing of silicone material into the mould and easy colour customization at the knuckles area of the dorsal and ventral aspect of the prosthesis. Clinical relevance This three-part mould technique helps to fabricate hollow prosthesis which increases retainability and at the same time allows easy packing of silicone material and easy colour customization at the knuckles area of the prosthesis.
