In the articulations of the index finger the posterior wall of the capsule has been divided transversely 

 across the middle of the joint, and the ends have been turned upwards and downwards ; in the 

 articulations of the thumb and the middle finder the capsule has been divided only between 

 the lateral ligaments, leaving these intact ; in the articulations of the ring and little fingers the 

 capsule has not been opened.
