Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Biomaterials Science

Background:

  • Arthritis of the proximal interphalangeal joint (PIPJ) significantly impacts hand function and quality of life.
  • Prosthetic joint replacement offers a potential solution for pain relief and functional restoration.
  • Pyrolytic carbon prostheses have emerged as a viable option for PIPJ reconstruction.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of prosthetic joint replacement for symptomatic arthritis of the proximal interphalangeal joint (PIPJ).
  • To assess pain reduction, functional improvement, patient satisfaction, and complication rates associated with PIPJ prostheses.

Main Methods:

  • A cohort of 20 patients with posttraumatic or idiopathic arthritis underwent PIPJ prosthetic replacement using 24 pyrolytic carbon implants.

The Use of Mixed Reality in Custom-Made Revision Hip Arthroplasty: A First Case Report

Published on: August 4, 2022

  • A dorsal approach was utilized, involving resection of joint surfaces while preserving collateral ligaments and the palmar plate.
  • Prostheses were inserted using a press-fit technique, followed by reapproximation of the dorsal aponeurosis.

    • Main Results:

    • An average range of motion of 50 degrees was achieved in the treated PIPJs.
    • Patients reported significant pain reduction (Visual Analog Scale: 0-3) and 80% expressed satisfaction with the surgical outcome.
    • Complications included three cases requiring revision to arthrodesis (one infection, two dislocations), and asymptomatic component migration in some cases. Nine prostheses developed painless squeaking without functional deficit.

    Conclusions:

    • Prosthetic joint replacement using pyrolytic carbon implants is an effective treatment for proximal interphalangeal joint (PIPJ) arthritis, offering substantial pain relief and functional recovery.
    • While complications such as infection, dislocation, and component migration can occur, the overall patient satisfaction and functional outcomes are favorable.
    • Careful patient selection, considering factors like ligament stability and extensor tendon integrity, is crucial for successful PIPJ prosthetic surgery.
