Summary
Cancellous bone grafting and Herbert screw fixation for acute scaphoid fractures with palmar comminution led to complications. Cortical bone grafting is recommended for palmar defects to improve scaphoid fracture outcomes.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Hand Surgery
Background:
- Acute scaphoid fractures, particularly those with palmar comminution, present treatment challenges.
- Herbert screw fixation and cancellous bone grafting are utilized for stabilizing these injuries.
Observation:
- Two cases of middle third scaphoid fractures with palmar comminution were treated with cancellous bone graft and Herbert screw fixation.
- Despite immobilization, one patient experienced secondary loss of reduction and dislocation.
- The second patient developed scaphoid dislocation, dorsiflexed intercalated segment instability, and required hardware removal due to joint irritation.
Findings:
- Cancellous bone grafting combined with Herbert screw fixation resulted in suboptimal outcomes in these cases.
- Secondary displacement and instability occurred despite initial fixation and immobilization.
- Complications included dislocation and the need for hardware removal due to secondary joint irritation.
Implications:
- The study suggests limitations of cancellous bone grafting for palmar defects in scaphoid fractures.
- Cortical bone grafting from the iliac crest is proposed as a potentially superior alternative for addressing palmar defects.
- This recommendation aims to improve stability and reduce complications in scaphoid fracture management.

01:26Flail Chest-II
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

01:27Fractures: Bone Repair
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 procedure...

01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...
