Bone Marrow Sampling and Transplants01:22

Bone Marrow Sampling and Transplants

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy the...
Tissue Transplantation01:24

Tissue Transplantation

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
The Biology of Tissue Transplantation
The biology of tissue transplantation hinges on the Major Histocompatibility Complex (MHC) molecules. These molecules...
Kidney Transplant I: Introduction01:28

Kidney Transplant I: Introduction

A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Area of Science:

  • Orthopedic surgery
  • Biomaterials engineering
  • Medical device technology

Background:

  • Scaphoid nonunions often require reconstruction, but this is not always feasible due to poor bone quality or arthritis.
  • Current salvage procedures for unreconstructable scaphoid nonunions can negatively impact wrist function.

Purpose of the Study:

  • To evaluate the efficacy of a patient-specific, 3-D-printed titanium scaphoid implant as an alternative treatment for unreconstructable scaphoid nonunions.
  • To assess functional and radiographic outcomes following implantation of custom 3-D-printed scaphoid prostheses.

Main Methods:

  • A retrospective case series involving 12 patients with unreconstructable scaphoid nonunions treated with 3-D-printed titanium implants.
  • Assessment of patient-reported outcomes, range of motion, grip strength, and plain radiographs before and after surgery.
  • Mean follow-up duration of 2 years and 8 months.

Main Results:

  • Postoperative improvements were observed in range of motion and patient-reported outcome scores, though motion improvement was not statistically significant.
  • Radiographic evaluation showed satisfactory alignment in all but one implant, with no progression of degenerative changes.
  • The 3-D-printed scaphoid implants demonstrated good integration and stability.

Conclusions:

  • Patient-specific 3-D-printed titanium scaphoid replacement presents a promising alternative to traditional salvage procedures for complex scaphoid nonunions.
  • This technique may offer a functional solution for patients with unreconstructable scaphoid fractures, preserving wrist function.
  • Further research with larger cohorts is warranted to confirm long-term efficacy and outcomes.
