Study Arms (2)
proximal phalangeal level
EXPERIMENTALinjection in the the tendon sheet over proximal phalanx of finger
volar MCP level
ACTIVE COMPARATORinjection above the A1 pulley volar to the MCP joint
Interventions
Injection of methyl prednisone and lidocaine in the tendon sheet at the level of the proximal phalanx
Injection of methyl prednisone and lidocaine in the tendon sheet volar to the MCP-joint
