Background Drug treatment for secondary hyperparathyroidism caused by chronic renal failure may be available at the early stage of the disease, but it is not as effective for serious patients. The aim of the study was to evaluate the effect of total parathyroidectomy combined with forearm autotransplantation in the uremic patients with secondary hyperparathyroidism.Methods From September 1999 through September 2006, parathroidectomy and autotransplantaUon was performed in 20 patients. The coherence between the results of preoperative parathyroid ultrasonography and surgical exploration were compared. The serum calcium concentration and intact parathyroid hormone （iPTH） were monitored preoperatively, intraoperatively, and postoperatively.Results A total of 71 hyperplastic parathyroid glands were resected in the 20 patients. The accordance rate of parathyroid localization between B-ultrasonography and intraoperaUve exploration was 94.4%. The average iPTH value was （110.90±67.42） ng/L, （433.80±243.72） ng/L, （48.80±42.69） ng/L, （229.04±172.68） ng/L and （232.39±224.05） ng/L at day 1, 2, 3, 7, 30 after operation respectively. The clinical symptoms were ameliorated and the levels of serum calcium concentration were controlled within the normal range after operation. Recurrent secondary hyperparathyroidism had happened in 1 case, 4 years postoperatively because of the development of autograft hyperplasia, and in another case 2 years postoperatively due to remnant of neck parathyroid glands. The clinical symptoms were all alleviated after re-operation. No surgical complication had occurred in any of the patients.Conclusions The total parathyroidectomy with forearm autotransplantation is feasible, safe, and effective for patients with secondary hyperparathyroidism in the short term. The long-term effects should be further investigated.

autologous grafts of double-strut fibular cortical bone plate to treat the fractures and defects of distal femur： a case report and review of literature

We reported a 23-year-old man who was involved in a high-speed motorcycle accident. He sustained a closed fracture at the right distal femur. The primary fracture happened on February 2008. He underwent open reduction and internal fixation with cloverleaf plate. And one hundred days after the surgery, the proximal screws were pulled-out, but the bone union was not achieved. Treatment consisted of exchanging the cloverleaf plate with a locking compression plate and using an auto-iliac bone graft to fill the nonunion gap. In July 2009, the patient had a sharp pain in the right lower limb. The X-ray revealed that the plate implanted last year was broken, causing a nonunion at the fracture site. Immediately the plate and screws were removed and an intramedullary nail was inserted reversely from the distal femur as well as a 7 cm long bone from the right fibula was extracted and longitudinally split into two pieces to construct cortical bone plates. Then we placed them laterally and medially to fracture site, drilled two holes respectively, and fastened them with suture. We carried on auto-iliac bone grafting with the nonunion bone grafts. The follow-up at 15 months after operation showed that the treatment was successful, X-ray confirmed that there was no rotation and no angular or short deformity. We briefly reviewed the literature regarding such an unusual presentation and discussed in details the possible etiology and the advantages of autologous double-strut fibular grafts to cope with such an intractable situation.
