Fractures: Bone Repair01:27

Fractures: Bone Repair

5.4K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Setting Time of Cement01:12

Setting Time of Cement

689
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

Rural Health Centers
Rural health centers are specialized care facilities in remote locations with very few medical personnel. The primary care providers who run the centers are mostly Registered Nurse Practitioners. Here, emergency treatment is provided to critically ill or injured patients before they are transferred to the closest hospital. Fortunately, due to advancement in technology, many rural healthcare facilities and professionals have easy access to diagnostic and treatment...

PPE Use in Healthcare Settings I: Donning

1.7K
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

PPE Use in Healthcare Settings II: Doffing01:10

PPE Use in Healthcare Settings II: Doffing

1.6K
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Summary

The clamshell osteotomy effectively treats acute fractures with lower extremity deformities and malunions. This surgical technique facilitates intramedullary nailing, leading to successful bone healing in complex cases.

Area of Science:

  • Orthopaedic Surgery
  • Traumatology
  • Skeletal Reconstruction

Background:

  • Managing lower extremity fractures with existing deformities or malunions is complex.
  • Traditional surgical approaches may be limited in these challenging cases.

Purpose of the Study:

  • To evaluate the outcomes of clamshell osteotomy in patients with acute lower extremity fractures and malunions/deformities.
  • To assess the efficacy of clamshell osteotomy in facilitating intramedullary nailing in complex fracture scenarios.

Main Methods:

  • Retrospective review of nine clamshell osteotomy cases across four trauma centers (January 2012 - January 2016).
  • Included cases with acute fractures in the setting of previous malunions or deformities.
  • Data collected on osteotomy healing and surgical outcomes.

Main Results:

  • All nine clamshell osteotomies achieved bone union within 15 months (average 6.8 months).
  • Four cases involved fractures with pre-existing malunions.
  • The technique proved successful in enabling intramedullary nailing.

Conclusions:

  • Clamshell osteotomy is a viable and effective surgical option for acute lower extremity fractures complicated by deformity or malunion.
  • This method facilitates successful intramedullary fixation in challenging orthopaedic cases.
  • The study supports clamshell osteotomy for improved outcomes in complex lower extremity fracture management.
