Summary
Dorsal lunate dislocation, a rare wrist injury from high-energy trauma, requires urgent treatment to prevent complications like avascular necrosis and chronic instability. This case highlights the rarity of this specific injury pattern.
Area of Science:
- Orthopedic Surgery
- Trauma Surgery
- Hand Surgery
Background:
- Lunate dislocation is a rare but severe wrist injury, typically resulting from high-energy trauma.
- While volar lunate dislocation is common, dorsal dislocation is exceptionally rare.
Purpose of the Study:
- To report a rare case of dorsal lunate dislocation following high-energy trauma.
- To emphasize the importance of urgent management for dorsal lunate dislocations.
Main Methods:
- A 55-year-old male sustained a dorsal lunate dislocation and bilateral carpal fractures after being hit by a car.
- The left wrist was treated with open reduction, internal fixation, and scapholunate ligament repair.
- The right wrist was managed conservatively.
Main Results:
- Successful surgical management of the left wrist's dorsal lunate dislocation and carpal fractures.
- Conservative management of the right wrist's injuries.
Conclusions:
- Dorsal lunate dislocation is an infrequent injury pattern, with few documented cases.
- Urgent intervention is crucial to mitigate risks of avascular necrosis, median nerve injury, complex regional pain syndrome, and chronic carpal instability.

02:37Disubstituted Cyclohexanes: cis-trans Isomerism
14.0K
Depending upon the different spatial orientation of the substituents, the disubstituted cycloalkanes exhibit two types of stereoisomers. The cis isomers have the substituents on the same side of the ring, whereas the trans isomers have the substituents on the opposite sides. These stereoisomers exhibit different physical properties and cannot be interconverted without breaking the carbon-carbon bonds.
In cyclohexane, the substituents can occupy different positions generating distinct isomers....

02:10Reduction of Alkynes to trans-Alkenes: Sodium in Liquid Ammonia
10.5K
Alkynes can be reduced to trans-alkenes using sodium or lithium in liquid ammonia. The reaction, known as dissolving metal reduction, proceeds with an anti addition of hydrogen across the carbon–carbon triple bond to form the trans product. Since ammonia exists as a gas (bp = −33°C) at room temperature, the reaction is carried out at low temperatures using a mixture of dry ice (sublimes at −78°C) and acetone.

5.4K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
