Clinical Study Of Percutaneous Compression Plating In The Treatment Of Femoral Neck Fracture

1.Comparative the early results of Percutaneous Compression Plating andMultiple Cannulated Screws for the treatment of femoral neck fracturesObjective: To compare the early clinical results of Percutaneous Compression Platingand Multiple Cannulated Screws in the treatment of femoral neck fractures．Methods: Fifty-two patients with femoral neck fracture were treated with MCS(n=27)or with PCCP (n=25) between December2010and October2011. All the patients werefollow-up for a mean time of9.6months.Functional outcomes were measured with HarrisHip Score. Period of union, amount of bleeding, time of operation and early complicationswere also recorded.Result: There was no statistical difference in the mean intraoperative blood loss andthe mean operative time between the two groups(P>0.05). All the52patients were follow-upfor a mean time of9.6months,ranged5-16months. A total of2cases suffered fromcomplications were in MCS group, including1cases of fixation failure, while there was nostatistical difference in the complication rate between the two groups. Fractures were allunion, and there was no statistical difference in the time of union between the twogroups(P>0.05). The comparition were made about the ambulant cases in3days, the casesmobilised full weight bearing in3months and Harris hip score in3months afteroperation，which had statistically important difference between the two groups(P <0.05).There was no statistical difference in Harris hip score between the two groups for the lastfollow-up(P>0.05).Conclusions:1.PCCP and MCS had comparative advantages like shorter operative time and lessblood loss. 2.The PCCP group made early ambulation,which facilitated early functional recoverybetter than the MCS group.2.Clinical study of Percutaneous Compression Plating in the treatment ofoboslete femoral neck fractureIn our unit,we treated for3cases of oboslete femoral neck fracture with PCCP.Case Ⅰ: Male was suffered oboslete femoral neck fracture for17months. It wasmissed for "left femur neck fracture" diagnosis in the initial treatment. CT scans: fracturewas malunited. First of all, we carried on traction of skin for2weeks. We chose approachof Watson-Jones, and made a15cm long incision. Then we undertake osteotomy.At last,we fixed fracture with PCCP. Fourth month later, fracture was basicly healed.At the lastfollow-up Harris hip score was recorded of85.Case Ⅱ: Male, aged48, was sustained oboslete femoral neck fracture with fracturenonunion for5months. X-ray: fracture lines obviously existed with two hollowcompression screws in place. He was treated with PCCP and quadratus femoris musclepedicle bone grafting. Six months later, radiography tip that fracture had been healed. Atthe last follow-up, Harris hip score was recorded of93.Case Ⅲ: Female,15years old, was found old femoral neck fracture nonunion for6months.She was treated with conservative method, which was proved failed. X-ray:fracture lines obviously. First, bone traction was used for2weeks. Taking Watson-Jonesapproach, we made a15cm long incision, then chose PCCP to restitution fracture. Weplaced injectable calcium sulfate in the gap of fracture. She can walk with crutches after2weeks with pain free.
