Event Description
Device report from synthes reports an event in (b)(4) as follows: this report is being filed after the review of the following journal article: puri a. , gulia a. , jambhekar n. , laskar s. , (2012) the outcome of the treatment of diaphyseal primary bone sarcoma by resection, irradiation and re-implantation of the host bone, the journal of bone and joint surgery, volume 94-b, pages 982¿988 (india) doi:10. 1302/0301-620x. 94b7. 28916. This study aims to analyse the results of all cases of primary extremity diaphyseal sarcomas reconstructed with extracorporeal radiation having a minimum follow-up of 24 months. Between march 2005 and september 2009, 32 patients (24 males , 8 females) with a mean age of 15 years (2 to 35) with diaphyseal sarcomas underwent en bloc resection with preservation of the adjoining joints and re-implantation of the tumour bone sterilised by extracorporeal radiation. Fixation was also done with various types of plates in 29 cases (standard dynamic compression plates (n
=
8),reconstruction plates (n
=
2) ,dynamic condylar screw plates (n
=
6),locking compression plates (n
=
9) custom-made plates (n
=
4), and intramedullary nails in the remaining three patients. The mean follow-up was 34 months (12 to 74). A total of 31 patients were available at a mean follow-up of 34 months (12 to 74). The following complications were reported as follows: death: a case of a 9 year old male (patient no. 2) with ewing's sarcoma treated with dcp died of the disease at the time of last review. A case of a 22 year old female (patient no. 3) with ewing's sarcoma treated with dcs died of the disease at the time of last review. A case of a 19 year old male (patient no. 4) with ewing's sarcoma treated with dcp died of the disease at the time of last review. A case of a 15 year old female (patient no. 11) with ewing's sarcoma treated with dcs died of the disease at the time of last review. A case of a 23 year old male (patient no. 14) with osteogenic sarcoma treated with dcs died of the disease at the time of last review. A case of a 35 year old male (patient no. 24 ) with osteogenic sarcoma treated with lcp died of the disease at the time of last review. Died before union. A case of a 16 year old female (patient no. 1) treated with dcs developed an infection and the graft was removed and the defect reconstructed using an antibiotic impregnated cement spacer. A case of a 14 year old male (patient no. 5) treated with dcp had synchronous local and distant recurrence. All were associated with disseminated disease and the recurrences were in soft tissue remote from the irradiated graft. A case of a 16 year old male (patient no. 6) treated with dcs developed an infection and the graft was removed. Patient had flail limb. A case of a 11 year old male (patient no. 10) treated with dcp developed post-operative skin necrosis requiring a flap cover. A case of a 16 year old male (patient no. 13) treated with dcs developed an infection after surgery for fracture after trauma and the graft was removed and the defect reconstructed using an antibiotic impregnated cement spacer. (one of the five cases/patients who had implant failure and nonunion was seen in at five diaphyseal osteotomy sites; they required open reduction and internal fixation with bone grafting. One of these patients subsequently developed an infection necessitating removal of the graft as described above (case 13). A case of a 17 year old male (patient no. 16) treated with lcp implant failure and nonunion was seen in five cases at five diaphyseal osteotomy sites; they required open reduction and internal fixation with bone grafting. A case of a 15 year old female (patient no. 19) treated with lcp had post-operative seromas formed and required drainage. Bone grafting was required for this patient. A case of a 15 year old female(patient no. 21) treated with dcp had vascular injury occurred due to the screws in the proximal tibia penetrating the vessel at operation and developed post-operative skin necrosis requiring a flap cover. A case of an 11 year old male (patient no. 22) treated with dcp developed post-operative skin necrosis requiring a flap cover. A case of an 18 year old male (patient no. 28) treated with lcp had vascular injury occurred at operation. A case of a 24 year old male (patient no. 29) treated with lcp had post-operative seromas formed and required drainage. Bone grafting procedures was required for this patient. (the same patient in fig 2: patient treated with extracorporeal irradiation and re-implantation with subsequent bone-grafting a) at eight months post-operatively showing delayed union, and b) at 18 months showing union. The arrows denote the osteotomy site. ) a case of a 12 year old patient female (patient no. 32) treated with lcp had non-union and implant removal. The same patient with a late wound dehiscence and her ulnar implant was removed (case 32)she had a nonunion at the distal osteotomy but was not a candidate for further surgical intervention because of cardiac toxicity due to doxorubicin. This report is for an unknown synthes constructs: plate/screws. This is report 4 of 9 for (b)(4). A copy of the literature article is being submitted with this medwatch.
