[Study on lateral hinge fracture during open wedge high tibial osteotomy]
1Department of Orthopaedics, the First Affiliated Hospital of Bengbu Medical College, Bengbu Anhui, 233000, P.R.China.
Summary
Open wedge high tibial osteotomy (OWHTO) requires attention to the lateral hinge to prevent fractures. Maintaining hinge integrity is crucial for successful healing and patient rehabilitation after OWHTO.
Area of Science:
- Orthopedic Surgery
- Biomechanics
- Surgical Complications
Background:
- Open wedge high tibial osteotomy (OWHTO) is a common procedure for knee osteoarthritis.
- Fracture of the lateral hinge during OWHTO can compromise surgical outcomes.
- The lateral hinge is critical for maintaining osteotomy stability.
Purpose of the Study:
- To review and summarize research on lateral hinge fractures in OWHTO.
- To analyze clinical experiences and outcomes related to this complication.
Main Methods:
- Literature review of domestic and international studies on OWHTO.
- Analysis of clinical data and surgical techniques for managing lateral hinge fractures.
Main Results:
- Lateral hinge rupture can lead to loss of correction, delayed healing, or non-union.
- Utilizing a 'safe zone' during osteotomy can protect the lateral hinge.
- TomoFix plates can provide stability if a fracture occurs.
- Management strategies, including exercise and weight-bearing, should be guided by fracture classification.
Conclusions:
- An intact lateral hinge is vital for optimal healing and rehabilitation after OWHTO.
- Clinicians must prioritize the integrity of the lateral hinge during OWHTO procedures.

A wedge is a simple machine that serves various purposes, such as adjusting the elevation of structural or mechanical parts, providing stability for heavy objects, and splitting a body into two parts. This versatile tool can amplify an applied force, making it easier to manipulate large or heavy objects.
Consider using a wedge to lift a heavy slab. Here, the wedge functions by converting the applied force into a much larger force directed almost perpendicular to the initial force. This...

1.0K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

01:27Fractures: 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...

01:27Cranial Bones: Lateral View
4.5K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Kidney, Ureter, and Bladder (KUB) StudiesKidney, Ureter, and Bladder (KUB) studies are standard diagnostic imaging procedures used to assess the anatomy of the urinary system. They are commonly utilized for patients experiencing abdominal pain or urinary symptoms. By using a simple X-ray of the abdomen, KUB studies can reveal structural and pathological abnormalities within the kidneys, ureters, and bladder. These studies are particularly valuable in diagnosing kidney stones, urinary...
