Modified surgical techniques of free vascularized fibular grafting for treatment of the osteonecrosis of femoral head: results from a series of 407 cases.

The goal for treatment of osteonecrosis of the femoral head (ONFH) is to relieve pain, preserve the contour of the femoral head, and delay the need for total hip arthroplasty. The free vascularized fibular grafting (FVFG) has been shown to support the subchondral architecture as well as restore local circulation for the necrotic femoral head in treatment of ONFH. This report aimed to present the clinical results of the use of a modified surgical technique of FVFG for treatment of ONFH.

Pain relief following osteonecrosis of the femoral head treated by free vascularized fibular grafting.

Background: Pain is the core and basic problem in the treatment of osteonecrosis of the femoral head (ONFH). However, it is unclear about the status of pain relief following ONFH treated by free vascularized fibular grafting (FVFG) and the level of pain relief contributed to clinical results. Therefore, we designed a consecutive and prospective study to investigate post-operative pain relief in the treatment of osteonecrosis of the femoral head by FVFG.

Injury-to-surgery interval does not affect the occurrence of osteonecrosis of the femoral head: a prospective study in a canine model of femoral neck fractures.

Background: It is controversial whether an early reduction and internal fixation can reduce the occurrence of femoral neck fracture-induced osteonecrosis of the femoral head (ONFH). This prospective study was designed to reflect the relationship between injury-to-surgery interval (ISI) and traumatic ONFH based on a canine model of femoral neck fractures.

Material/methods: Twenty-four dogs were equally divided randomly into 3 groups.

Free vascularised fibular grafting combined with a locking plate for massive bone defects in the lower limbs: a retrospective analysis of fibular hypertrophy in 18 cases.

Objective: Free vascularised fibular grafting (FVFG) could be a good option for the restoration of massive bone defects in lower limbs when combined with use of a locking plate. The progress of fibular hypertrophy is closely related to regain of function, as well as to prevention of stress fractures. Multiple variables affecting fibular hypertrophy were investigated in the current study to elucidate correlative factors.

Free vascularized fibular grafting in combination with a locking plate for the reconstruction of a large tibial defect secondary to osteomyelitis in a child: a case report and literature review.

Although a large skeletal defect secondary to osteomyelitis in children is not an uncommon problem, there are no descriptions of the management of such a defect with a free vascularized fibular graft in combination with a locking plate. We performed such a technique, after radical debridement and systemic antibiotic treatment, on a 13-year-old boy suffering from a large 10 cm tibial defect secondary to osteomyelitis. Primary union of the graft was achieved at 6 months.

Treatment of aseptic nonunion after intramedullary nailing fixation with locking plate.

Objective: To evaluate the safety and efficacy of locking plate combined with bone grafting in the treatment of aseptic nonunion following intramedullary nailing fixation of fractures of the long bones.

Methods: Thirty-eight consecutive patients treated in our hospital between January 2004 and December 2006 were included in this retrospective study. The nonunions included 20 femurs, 15 tibias, and 3 humeri.

[The surgical technique and follow-up of the treatment with locking internal fixation on long bone nonunion of extremities].

Objective: To report the outcome of long bone nonunion of humerus, femur and tibia treated with locking internal fixation and bone graft.

Methods: From February 2003 to October 2006, locking internal fixation and bone grafting were employed to treat 5 cases at humerus, 33 cases at femur, 23 cases at tibia. Forty-four of the patients were men, and 17 were women.
