BACKGROUND:Complex scapular fractures were mainly treated by implant fixation. Standard fixation approach (Judet approach) had long incision and big trauma. With the application of spiral CT and three-dimensional reconstruction, minimal y invasive incision could be designed before implant fixation, and then fixation could be finished by physicians. Thus, trauma was reduced and repair effect was elevated. OBJECTIVE:To observe the effects of the three-dimensional reconstruction design combined with titanium plate reconstruction or lag screw for treatment of scapular fractures. METHODS:From February 2007 to January 2012, 33 cases of scapular fractures were enrol ed from Department of Orthopedics, No. 1 Hospital of Qinhuangdao in China. They were scanned by three dimensional reconstruction of CT before implant fixation to identify the regions needed to be repositioned and fixed. Thus, minimal y invasive incision of implant fixation was designed. The dissection of skin, subcutaneous tissue and muscle was reduced. Reposition was performed. Titanium plate and/or lag screw were used for fixation. RESULTS AND CONCLUSION:The operation lasted for 90-130 minutes in 33 patients, with intraoperative blood loss for 300-400 mL. Fracture was total y healed, and the healing time was 2-4 months. The fol ow up lasted for 12-24 months. According to Hardegger standard, there were excellent in 17 cases, good in 12 cases, average in 3 cases and poor in 1 case, with an excellent and good rate of 88%. These results suggested that three-dimensional reconstruction design combined with minimal y invasive incision treatment for scapular fractures showed fewer traumas, can complete the satisfactory fracture reduction and implant fixation, and obtain good repair effect.

BACKGROUND:The previous literatures have reported that the aneurysmal bone cyst has a high recurrence rate after curettage treatment.
OBJECTIVE:To investigate the effect of less invasive stabilization system plate fixation combined with bone cement in the treatment of distal femoral aneurysmal bone cyst.
METHODS:A retrospective analysis was conducted in 19 patients with distal femoral aneurysmal bone cyst who treated with less invasive stabilization system plate fixation combined with bone cement in the First Hospital of Qinhuangdao between January 2002 and January 2012. The purpose of the treatment of aneurysmal bone cyst was to completely remove the cyst and prevent recurrence, and to repair and reconstruct the structure and function of the damaged tissues through implant fixation.
RESUTLS AND CONCLUSION:The 19 patients were fol owed-up for 1-3 years after treated with less invasive stabilization system plate fixation combined with bone cement, and 18 cases recovered wel , one case had recurrence at 2 years after treatment. Complete removal of aneurysmal bone cyst is the key for the prevention of recurrence. The less invasive stabilization system plate is the combination of advantages of intramedul ary nail and the biological locking plate technology, which has many advantages in the treatment of aneurysmal bone cyst. Fil ing the lesion area with bone cement had certain kil ing effect on tumor, and can increase the bone strength in the lesion area. The surgical treatment of distal femoral aneurysmal bone cyst is to clear the cystic lesions firstly, and then to prevent the recurrence through less invasive stabilization system plate fixation combined with bone cement.
