Wrinkle corner. Epidemic lunate dislocation and a single-handed method of reduction

Area of Science:

• Orthopedic Surgery
• Hand and Wrist Injuries
• Musculoskeletal Trauma

Background:

• Lunate bone dislocation is a common carpal injury.
• Traditional reduction methods require difficult sustained traction.
• A simplified technique was developed during wartime for wrist dislocations.

Purpose of the Study:

• To present a simplified method for reducing lunate bone dislocations.
• To overcome the challenges of sustained traction in traditional methods.
• To improve the efficiency and effectiveness of carpal injury reduction.

Main Methods:

• A novel technique involving surgeon forearm leverage with interlocked fingers was employed.
• This method provides significant mechanical advantage and sustained traction.
• It allows the surgeon's other hand to apply direct pressure on the dislocated bone.

Main Results:

• The simplified method successfully reduced lunate bone dislocations.
• It overcomes the difficulties associated with sustained traction.
• The technique was effective even in a delayed bilateral case missed for a week.

Conclusions:

• The described method offers a mechanically advantageous and simpler approach to lunate dislocation reduction.
• This technique enhances surgical efficiency by freeing a hand for direct manipulation.
• It provides a viable alternative for treating complex or delayed carpal dislocations.
