Inca bones or interparietal (supernumerary) bones are rarely seen among dry human skulls. Their frequency of presentation is much less than that of sutural or Wormian bones. Inca bones or interparietal (supernumerary) bones are accepted as normal variants most often found in the occipitoparietal region of the skull. Their characteristic shape, a triangle, resembles a monument design of the Inca tribe of South America and Latin America. The significance of the presence of these variants is that Inca bones or interparietal bones may be mistaken for a skull fracture. They may also be very useful in forensic identification of an unknown individual.展开更多

Method: We describe a technique of osteotendinous suturing through the tibial tuberosity for suturing of the medially elevated periosteum. Result: This is an easily reproducible technique which results in very early mobilisation and no additional complications and has several advantages over other methods of closure. Conclusion: The osteotendinous technique can be used for medial arthrotomy closure after correction of severe varus deformities and also after partial patellar tendon avulsions in total knee arthroplasty surgeries.展开更多
