This report shows a rare case of avascular necrosis of vertebra body after insertion of interspinous device after insertion of interspinous device and its plausible cause. A 82-year-old woman presented with severe back pain for 1 week without injury. In her history, she had undergone decompression and implantation of L4-5 interspinous device for the relief of neurogenic claudication at 4 year a...

A neglected femoral neck fracture is one where there has been a delay of more than 30 days to seek medical help from the time of the original injury. Among the spectrum of femoral neck fractures, the neglected fracture in a young adult (age <60 years) is one of the most challenging to treat if femoral head salvage is attempted. The main complication is avascular necrosis (AVN) of the femoral he...

Purpose In situ fixation for mild to moderate slipped capital femoral epiphysis (SCFE) remains an acceptable treatment methodology in most centers. Satisfactory fixation results have been reported with the procedure using either the fracture table or radiolucent table, both of which allow the hip to be imaged during the procedure. The position of the pin within the center of the femoral head is...

Introduction Electromagnetic stimulation is a common therapy to support bone healing in cases of avascular necrosis or pseudarthrosis. An electrostimulative screw implant (Asnis III s-series screw in Figure 1) is used to stimulate bone regeneration in the treatment of femoral head avascular necrosis. To enable positive outcome of the treatment, optimal positioning of the electric implant is cri...

Mechanical factors have now been excluded as the main cause of non-union in fractures of the femoral neck : the development of efficient methods of internal fixation has removed this source of non-union and the chief remaining cause is disturbance of the circulation of blood to the capital fragment. The incidence of avascular necrosis of the femoral head appears to depend upon normal variations...

OBJECTIVE We wanted to analyze the factors affecting the results of multiple cannulated screws fixation in patients less than 60 years old with femoral neck fracture (FNF). METHODS We reviewed 52 patients (30 males, 22 females) who were treated with multiple cannulated screws fixation for FNFs. They were followed up for more than one year during January 2002 to December 2012. They were classi...

The incidence and long-term outcome of undisplaced fatigue fractures of the femoral neck treated conservatively were examined in Finnish military conscripts between 1970 and 1990. From 106 cases identified, 66 patients with 70 fractures were followed for a mean of 18.3 years (11 to 32). The original medical records and radiographs were studied and physical and radiological follow-up data analys...

The purpose of this study was to determine the effect of depression on femoral head avascular necrosis (AVN) from femoral neck fracture in patients younger than 60 years and the relationship between depression and postoperative quality of life. The Beck Depression Inventory-II (BDI-II) was completed by 641 patients (352 men and 289 women; average age, 41.7±10.2 years; range, 20-60 years) postop...

Cancer patients have a better prognosis now than in the past. An estimated 66% of patients diagnosed with cancer between 1996 and 2004 were alive at 5 years.1 As patients are living longer after treatment, long-term complications associated with treatment are becoming a greater issue. Avascular necrosis, also referred to as osteonecrosis, ischemic necrosis, subchondral avascular necrosis, asept...
