Abstract
IntroductionA case of an osteolysis by Mitek anchor-suture is presented.Case presentationA case of index finger's flexor digitorum profundus tendon primary reconstruction with the use of Mitek anchor is presented here. Within a 14 month period, Mitek suture anchor caused local foreign body reaction with osteolysis and ulceration of the palmar skin of the finger while on the other hand tendon's healing was successfully completed.ConclusionMitek anchor-sutures can cause an aseptic inflammatory reaction which represents a typical biologic response to a foreign body. Concomitant osteolysis can drive to loosening and migration of the implant.
Highlights
A case of an osteolysis by Mitek anchor-suture is presented.Case presentation: A case of index finger's flexor digitorum profundus tendon primary reconstruction with the use of Mitek anchor is presented here
In our case the use of such an anchor resulted in flexor tendon healing despite the fact that it was complicated by a foreign body reaction
Granulomatosis caused by a biological foreign body reaction to used materials drove to ulcer creation and this aseptic inflammation is responsible for surrounding osteolysis
Summary
Mitek anchors are frequently used in treatment of flexor and extensor tendons' laceration and avulsion. In our case the use of such an anchor resulted in flexor tendon healing despite the fact that it was complicated by a foreign body reaction (granulomatosis and osteolysis). These findings led to Mitek anchor removal 14 months after the implantation. Clinical examination revealed a transverse wound of approximately 1 cm on the palmar side of the index finger just proximally to the DIP joint with associate inability of flexion of the distal phalange. Patient attended our clinic 14 months later complaining of a recurrent ulcer on the palmar side of the distal phalange (Figure 1a) of the finger during the last two months.
