AI Article Synopsis
- The study aimed to assess the long-term outcomes of silastic implants used to treat hallux rigidus, noting previous short-term successes but concerns about longevity.
- Involving 108 feet from 83 patients over an average follow-up of 8.5 years, the study measured patient outcomes using various scoring systems and assessed for complications.
- Results indicated a mean AOFAS score of 77.5 and high patient satisfaction (average VAS of 7.73), suggesting that silastic implant arthroplasty is an effective treatment despite some cases of osteolysis.
Article Abstract
Purpose: The short-term results of silastic implant of the first metatarsophalangeal joint (MTPJ) have been successful. However, reservations exist regarding long-term results. The aim of this study was to evaluate long-term outcome of silastic implant prosthesis in treatment of hallus rigidus.
Methods: This was a retrospective study, with 108 feet in 83 patients, operated upon between 1988 and 2003. Mean age at operation was 55 years (SD 8.1) with a follow-up period of 8.5 years. Outcome measures included the American Orthopaedic Foot and Ankle Scoring system(AOFAS), passive and active arc of motion. Patients' satisfaction was assessed using the visual analogue scale. All the patients had anteroposterior and oblique views and were assessed for loosening and osteolysis. Pedobarographic studies were performed using the Musgrave Footprint. Complications and revisions were recorded.
Results: The mean total AOFAS score was 77.5 (SD 13.4). Mean active and passive arc of motions were 36.8 degrees (SD 19.13) and 46.82 degrees (SD 17.19), respectively. Patient satisfaction showed mean VAS of 7.73 (SD 2.41). Prostheses were removed in three feet at three, five and seven years respectively because of persistent pain. Radiologically 25 feet (23 %) had osteolysis but were non progressive and didn't correlate with the functional outcome.
Conclusion: We can conclude that silastic implant arthroplasty is an effective procedure in hallux rigidus management with satisfactory functional outcome and high patient satisfaction.

Silicon integrated circuits (ICs) are central to the next-generation miniature active neural implants, whether packaged in soft polymers for flexible bioelectronics or implanted as bare die for neural probes. These emerging applications bring the IC closer to the corrosive body environment, raising reliability concerns, particularly for chronic use. Here, we evaluate the inherent hermeticity of bare die ICs, and examine the potential of polydimethylsiloxane (PDMS), a moisture-permeable elastomer, as a standalone encapsulation material.

The voluntary recall of textured breast implants due to their association with breast implant-associated anaplastic large cell lymphoma has resulted in the loss of the primary advantage of the textured surface: positional stability. We have engineered a novel soft gel-filled smooth implant with a surface that promotes positional stability without texture, known as the positionally stable smooth implant (PSSI). Miniature anatomically shaped breast implant shells were fabricated from polydimethylsiloxane using 3D-printed molds.

Objective: Type 1 Thyroplasty is a well-established procedure used for medializing an immobile vocal fold. Silastic and Gore-Tex are the two most common materials used to accomplish this, but comparative data on their relative efficacy are scarce. We sought to compare outcomes between Silastic and Gore-Tex implants via systematic review and meta-analysis for unilateral vocal fold immobility.

Technologies for axon guidance for disease models and bottom up investigations are increasingly being used in neuroscience research. One of the most prevalent patterning methods is using polydimethylsiloxane (PDMS) microstructures due to compatibility with microscopy and electrophysiology which enables systematic tracking of axon development with precision and efficiency. Previous investigations of these guidance platforms have noted axons tend to follow edges and avoid sharp turns; however, the specific impact of spatial constraints remains only partially explored.

Article Synopsis
- Flap transplantation is often used for extensive wounds, relying on stable blood flow, and previous studies showed that high doses of estrogen improve flap survival but may cause side effects due to unnatural concentrations.
- This study tested the effects of sustained-release estrogen capsules at lower, physiological levels on flap survival in ovariectomized mice, focusing on blood perfusion and wound healing indicators.
- Results indicated that lower doses of estrogen improved blood flow and reduced necrosis while impacting specific markers related to tissue oxygen levels and cell death, suggesting that physiological estrogen levels can still be beneficial for flap survival.
