The treatment of radius head comminuted fractures remains controversial. The radius head excision and the radius head arthroplasty have been proposed as the main treatment methods. We present 13 cases, 6 men and 7 women aged 25–68 years old with radius head comminuted fractures Mason type III during 2005–2006. Elbow dislocation was also present in 3 patients, ulnar comminuted fracture in 1 patient and ipsilateral cubitocarpal comminuted fracture in another patient. All patients were managed operatively with radius head removal and cementless monopolar metallic prothesis placement. The others musculoskeletal injuries were managed at the same time. The average hospitalization was 6.8 days without complication postoperatively. 12 cases were followed up and the average follow up period was 26 months. In 6 cases the results were excellent, in 3 cases the results were moderate and in 3 cases the results were bad. We believe that the arthroplasty is the acceptable method in radius head comminuted fractures management especially in cases were complicated elbow damages are present.
We present our clinical experience in treating atrophic non-union of long bones by injecting, percutaneously, autologous bone marrow aspirate concentrated as a source of progenitors stem cells Bone marrow aspirated from the iliac crest contains progenitor cells that can be used to obtain bone-healing of non-union. However, its efficacy appears to be related to the number and concentration of progenitors in the graft. The last three-year period, 11 patients (8 men-3 women) with established atrophic non-union were treated in our department. In all cases, the gap between the fragments was smaller than 5 mm. A constant volume of 60+60 ml of marrow were aspirated from both iliac crests and centrifuged for 15 minutes aiming at the increase of concentration of progenitor-mononucleotide cells. An average volume of 20 ml (+/− 2) concentrated bone marrow was injected percutaneously, under C-arm, at the site of non-union. The graft contained an average of 272.64 x 10(6)/ ml mononucleotide cells. The evaluation of treatment was based on the clinical and radiological findings after 3, 6, 9 and 12 months. However, prior to administration of bone marrow stem cells, there was no case with evidence of ongoing deep sepsis. Bone union was obtained in 10 out of 11 patients (full weight bearing, callus formation in 3 out of 4 cortices). In one case a second operation was needed due to impaired indications of treatment. However, in all cases, there were no signs of local or systematic complications. Percutaneous concentrated bone marrow grafting is an efficient and safe method, for treating atrophic non-unions, with a minimal invasion technique. Contraindications for the above technique are a gap larger than 5 mm and a preexisting angular and axial deformity.
We evaluated the clinical outcome of IM nailing for the treatment of femoral shaft pseudarthrosis in patients who had multiple failed plate osteosyntheses. From January 2000 untill April 2001, 20 (19 male-1 female, mean age 28) patients were treated because of femoral shaft non-union in our institution. All patients had two or more failed plate osteosyntheses. There were no septic non-unions in this group. Eight patients had an established non-union on an average of nine months post-op and the remaining eleven had radiological and clinical evidence of implant failure. There was no segmental bone loss, hi all patients the implants were removed and nailing was performed. Extensive periosteal stripping, bone necrosis and soft-tissue scaring were constant findings in all patients. Twelve patients received interlocking nails. Eight femurs were grafted with iliac crest bone graft. All patients were followed by serial x-rays until union. There were no postoperative complications. All pseudarthroses were healed within an average of 9.7 months (8–12). Non-unions which received bone graft (eight out of twenty) in day one, were healed faster than those which didn’t. There were no re-operations among these patients. Among the remaining ten patients five were grafted five to six months postoperatively and three had had nail dynamization. IM nailing for femoral shaft non-unions after multiple failed plate osteosyntheses is a safe and effective method of treatment. Autologous bone graft reduces healing time and re-operation rate.
