OBJECTIVE To evaluate the clinical effect of total hip joint replacement and hemiarthroplasty in treatment of fracture of femoral neck in old patients. METHODS One hundred and ten cases with femoral neck fracture in the aged, 70 to 106 years old, from Aug 1990 to Aug 1999 were reviewed, 96 cases were followed up, among which 52 cases received total hip joints replacement and the other 44 cases received hemiarthroplasty. All of the 96 cases were followed up for 15 to 112 months, averaged 51 months, and were evaluated in operation procedures, post-operative recovery and joint function according to Harris Scoring. RESULTS The operation time of total hip joints replacement was 20 minutes longer, bleeding volume was 120 ml larger, and post-operative drainage was 140 ml more, in average, than those in hemiarthroplasty. There was no obvious difference between the two types of operation in bed-resting time, length of stay and hospitalizing costs. According to Harris Scoring, there were 38 cases of excellent in hemiarthroplasty (86.4%) and 48 cases of excellent in total hip joints replacement (92.3%). CONCLUSION Both of the artificial joint replacements are reasonable choices for treatment of fracture of femoral neck in old patients, but total hip joints replacement is recommendable for those comparatively younger patients with good systematic status, and hemiarthroplasty is a good option for those elderly with some systematic diseases.
Objective To estimate clinical effect ofspin iliac deep vascular pedicled periosteum flap in repairing traumatic femoral neck of theca inside fracture in young and middleaged. Methods From April 1993 to September 2001, 12 cases of traumatic femoral neck fracture were given diaplastic operation with fixation of 3 centre hollow pressed bolt and were conducted under os traction bed and "C" arm X-ray machine. Spin iliac deep vascular pedicled periosteum flap wasstripped off, and transferred to the front of femoral neck fundus,then transplanted to the narrow inside of fracture through outer open door of articular capsule.Results All patients were followed up for 17 years. All fracture healedwithout femoral head necrosis, but mild arthritis appeared in 7 cases.Conclusion Vascular pedicled periosteum flap transfer of young and middle-aged femoral neck fracture, by decompression of femoral neck and reconstruction of blood circulation, can promote the fracture healing and decrease the wound and blood circulation destroy.
Objective To evaluate the clinical effect of cannulatedscrew on treatment of femoral neck fracture(FNF). Methods Forty-two FNFpatients were treated by using cannulated screw from January 2001 to December 2005.There were 22males and 20 females with an average age of 41 years (19-59 years). Fracture was caused by traffic accident in 21 cases, by falling from height in 14 cases and by bruise in 7 cases. All cases were fresh fracture. According to Garden criterion for typing, 15 cases were classified as type Ⅱ, 16 cases as type Ⅲ and 11 cases as type Ⅳ . It was 7 hours to 15 days from injury to operation. Results Thepatients were followed up for 1-6 years with an average of 2.5 years. The average fracture union time was 6.5 months. Three patients had ischemic necrosis of femoral head, andloosening and breakage of screw and rob was observed in 1 case. According to Brumback criterion for hip joint function, the result was excellent in 18 cases, good in 20 cases and bad in 4 cases, and the excellent and good rate was 90.4%. Conclusion Cannulated screw fixation is a good method to treat FNF in young adults. It can improve the rate of fracture union and reduce the rate of avascular necrosis of femoral head.
OBJECTIVE To summarize the clinical results of hollow compression screw in treatment of fracture of neck of femur in the aged. METHODS: From November 1993 to October, 1998, 52 aged patients with several types of fracture of neck of femur were treated; among them, there were 25 males and 27 females aged from 60 to 83 years (70 years on average). There were 48 cases of fresh fracture and 4 cases of old fracture. Forty-two cases were performed closed reduction internal fixation, 10 cases with open reduction internal fixation. RESULTS: All the patients could sit by themselves 4 to 6 days after operation, and could walk with a crutch 10 to 15 days after operation. The mobility of hip joint was nearly normal 4 weeks after operation. All the patients were followed 26 to 84 months, 48.5 months on average. Bone union was achieved in 50 cases, nonunion in 2 cases. The average healing time was 4.7 months. There were no other complications, such as ankylosis and muscular atrophy, but ischemic necrosis in 3 cases. CONCLUSION: This method has following advantages, convenient manipulation, less injury, stable fixation, and the short-term recovery, which avoid some common complications. It is a reliable method worthy of popularizing.
Objective To study the application and the curative effect of compressed screw and sartorius bone flap in treating femoral neck fractures in youth or middle age. Methods From February 1996 to December 2004, 86 patients with femoral neck fracture were treated by open reduction compressed screw and sartorius bone flap, aging from 21 to 49 years. Fracture was caused by traffic accident in 35 cases, fall from height in 27 cases and fall in 24 cases. Accoding to Garden classification, 23 cases were type Ⅱ, 25 cases were type Ⅲ, and 15 cases were type Ⅳ. We analyzed fracture healing and evaluate function by observation of the postoperative X-ray films. Results Of the 86 patients, 62 were followed up 6 months to 7 years (2 years and 5 months on average). According to Weijie’s criterion for nonunion and necrosis offemoral head, nonunion occurred in 4 cases; the healing rate of fracture was 93.5%. In healed patients, necrosis of femoral head occurred in 7 cases (11.3%) after 3 years. The results of hip joint function evaluation were excellent in 44 cases, good in 8 cases, fair in 6 cases and poor in 4 cases; and the excellent and good rate was 83.9%. Conclusion Compressed screw and sartorius bone flap was simple and effective for femoral neck fractures in youth or middle age.
Objective To evaluate the feasibility and short-term effectiveness of polyaxial locking plate for fixation of femoral neck fracture in the middle-aged and elderly patients. Methods A retrospective analysis was made on the clinical data of 13 patients with femoral neck fracture undergoing fixation with polyaxial locking plates between September 2013 and June 2015 (group A) and 13 patients with femoral neck fracture undergoing fixation with three cannulated screws in the same period (group B). There was no significant difference in gender, age, side, cause of injury, Garden type, type of fracture position, type of Pauwels angle, Singh index, time between injury and operation, and preoperative complications between 2 groups (P>0.05). The femoral neck shortening at 1 year postoperatively, and fracture nonunion, femoral head necrosis, and Harris hip score at last follow-up were compared between 2 groups. Results The follow-up time was (19.23±3.98) months in group A and (18.00±3.61) months in group B, showing no significant difference between 2 groups (t=2.063,P=0.417). No femoral head necrosis occurred in group A, but head necrosis occurred in 1 case of group B, and hemiarthroplasty was performed. There was no significant difference in the rate of femoral head necrosis between 2 groups (χ2=0.000,P=1.000). Bone union was obtained in the other patients of 2 groups. The Harris hip score of group A (85.23±2.95) was significantly higher than that of group B (81.92±3.64) at last follow-up (t=2.064,P=0.018). No infection or internal fixation failure occurred in 2 groups. One case had pain at the outer thigh at 1 month after operation in group A, but pain relief was achieved at 3 months after operation. At 1 year after operation, no femoral neck shortening occurred in group A, but degree I, II, and III femoral neck shortening was observed in 3, 2, and 8 cases of group B, respectively, showing significant difference between 2 groups (Z=–4.714,P=0.000). Conclusion Although fixation with polyaxial locking plate for femoral neck fracture in the middle-aged and elderly patients has similar femoral head necrosis rate to fixation with cannulated screws, it has advantages in preventing neck shortening and improving hip joint function after operation.
Objective To compare the effectiveness of biplanar vertical fixation and inverted triangle fixation with hollow screw for Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients. Methods The clinical data of 55 young and middle-aged patients with Pauwels type Ⅲ femoral neck fracture between June 2021 and December 2022 was retrospectively analyzed. All patients were treated with closed reduction and internal fixation with hollow screws, 25 cases were treated with biplanar vertical fixation (study group), 30 cases with inverted triangle fixation (control group). There was no significant difference in gender, age, affected side, cause of injury, underlying diseases, and time from injury to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, guide needle puncture times, starting time of weight bearing, time of full weight bearing, time of fracture healing, and complications were recorded and compared between the two groups. The hip joint function was evaluated by Harris score at 1 day, 6 months, 12 months after operation, and at last follow-up, and the pain relief was evaluated by visual analogue scale (VAS) score. The femoral neck shortening was measured on the X-ray film at last follow-up. Results All patients were followed up 12-31 months (mean, 22.0 months), and there was no significant difference in follow-up time between the two groups (P>0.05). The operation time, intraoperative blood loss, and fluoroscopy times in the study group were higher than those in the control group, but the difference was not significant (P>0.05). The guide needle puncture times in the study group was more than that in the control group, and the time of starting weight bearing and the time of full weight bearing in the study group were shorter than those in the control group, the differences were significant (P<0.05). Bony healing was achieved in both groups, and there was no significant difference in fracture healing time between the two groups (P>0.05). No osteonecrosis of the femoral head and incision-related complication was found in the two groups during follow-up, and the femoral neck shortening length in the study group was significantly shorter than that in the control group at last follow-up (P<0.05). There was no significant difference in Harris score between the two groups at 1 day after operation (P>0.05), and the Harris score of the study group was significantly better than that of the control group at other time points (P<0.05); there was no significant difference in VAS score between the two groups at each time point after operation (P>0.05). Conclusion Compared with the inverted triangle fixation, the treatment of Pauwels type Ⅲ femoral neck fracture with biplanar vertical fixation can effectively reduce femoral neck shortening without affecting fracture healing, and improve hip joint function in early stage.
