surfaces; plantar (theoretical), a band between the plantar sur- 

 faces, subjacent to the long plantar ligament; and interosseous, 

 strong fibres anteriorly between the contiguous surfaces of the 

 bones. The synovial membrane may be distinct, but often com- 

 municates with those of the scapho-cuneiform and scapho- 

 cuboid joints. [312] 



Tarso-metatarsal Joints. There are three, the inner, middle, 

 and outer, as follows. [313] 



The inner joint is between the distal end of the internal cu- 

 neiform and proximal end of the base of the first metatarsal. 

 Its capsule is complete but the dorsal and plantar tarso-metatar- 

 sal bands are its strongest parts ; a separate synovial membrane 

 lines it. [313] 



The middle joint is between the three cuneiforms and the 

 bases of the second, third, and part of the fourth metatarsal. 

 Its parts are interlocked as the second metatarsal projects 

 backward between the internal and external cuneiforms, while 

 the external cuneiform projects forward between the second 

 and fourth metatarsals. It has a complete capsule with a sep- 

 arate synovial membrane, which is prolonged forward on both 

 sides of the second and third metatarsals, and backward be- 

 tween the inner and middle cuneiforms to open into the sca- 

 pho-cuneiform joint. Of the tarso-metatarsal ligaments, the 

 dorsal are antero-posterior flat bands, one running from the 

 external cuneiform to the third metatarsal, and one from each 

 cuneiform to the second metatarsal; the palmar are weaker 

 bands similarly disposed, with oblique bands between the in- 

 ternal cuneiform and second and third metatarsals. Of the 

 three interosseous cuneo-metatarsal ligaments, the inner connects 

 the outer side of the internal cuneiform with the inner side of 

 the second metatarsal; the middle connects the inner side of 

 the external cuneiform with the outer side of the second meta- 

 tarsal; and the outer connects the adjacent outer sides of the 

 external cuneiform and third metatarsal. [313] 



The external joint is between the cuboid and the proximal
