AB Tenosynovitis,  an  inflammation  of  the  tendon  and  surrounding  synovial  sheath,  is  characterized  by  pain  and  tenderness.  Pyogenic  flexor  tenosynovitis  is  a  serious  tendon  sheath  infection  resulting  from  puncture  wounds,  local  extension,  or  hematogenous  spread.  It  is  characterized  by  the  four  cardinal  Kanavel  signs  (see  Fig.  12.28).  Tenosynovitis  may  be  complicated  by  fibrosis  and  adhesions,  leading  to  stiffness,  loss  of  function,  and  tendon  necrosis.  Inflammatory  flexor  tenosynovitis  is  typically  due  to  rheumatoid  arthritis,  overuse,  diabetes  mellitus,  or  connective  tissue  disorders.  The  time  course  is  typically  more  indolent  than  pyogenic  flexor  tenosynovitis,  although  the  sequelae  can  be  similar.  Intersection  syndrome  is  tenosynovitis  of  the  radial  wrist  extensors.  It  causes  pain,  swelling,  and  crepitus  of  these  muscle  bellies  in  the  distal  third  of  the  dorsoradial  forearm.
