  • FREE VASCULARIZED FIBULAR ASSOCIATED WITH ILIAC GRAFT TO TREAT OLD FEMORAL NECK FRACTURE

    【Abstract】 Objective To evaluate the cl inical outcome of free vascularized fibular associated with il iac graft intreatment of old femoral neck fracture. Methods From January 1994 to January 1997, 76 cases of old femoral neck fracture were treated with free vascularized fibular associated with il iac graft, including 54 males and 22 females, aging from 24 to 48 years with an average of 31.5 years. All of these fractures resulted from injury. There were 20 cases of Garden II, 41 of Garden III and 15 of Garden IV. Based on the location of fracture, there was 26 cases of subcapital, 42 cases of transcervical and 8 cases of basal. Sixty-five cases were treated with internal fixation, 7 cases with skin traction and 4 just with staying in bed. Their Harris score were from 52 to 72 with an average of 65.6. The time from injury to operation was 2-24 months. The size of free vascularized fibular was 6-8 cm and il iac graft was 3.0 cm×2.0 cm×1.5 cm. Results In 76 cases, 68 were followed up and all fractures healed within 4 to 6 months with an average of 5.2 months. The increased density in femoral head was observed 1 year after operation. After 10 years of operation, normal hip function was achieved in 63 cases(followed up 10.1 -12.4 years with theaverage as 10.5 years); the Harris score was 87.5 (84 to 94). The structure of femoral head was normal and the grafted fibular and il iac bone healed with the femoral, no elapse or cyst occurred. Five cases had been compl ied with total hip replacement for femoral head necrosis or other. Conclusion Free vascularized fibular associated with il iac graft is a good method to treat old femoral neck fracture.

  • Effectiveness of guide plate with mortise-tenon joint structure combined with off-axis fixation in treatment of Pauwels type Ⅲ femoral neck fractures

    Objective To investigate the effectiveness of using 3 hollow compression screws combined with 1 screw off-axis fixation under the guidance of three-dimensional (3D) printed guide plate with mortise-tenon joint structure (mortise-tenon joint plate) for the treatment of Pauwels type Ⅲ femoral neck fractures. Methods A clinical data of 78 patients with Pauwels type Ⅲ femoral neck fractures, who were admitted between August 2022 and August 2023 and met the selection criteria, was retrospectively analyzed. The operations were assisted with mortise-tenon joint plates in 26 cases (mortise-tenon joint plate group) and traditional guide plates in 28 cases (traditional plate group), and without guide plates in 24 cases (control group). There was no significant difference in the baseline data of gender, age, body mass index, cause of injury, and fracture side between groups (P>0.05). The operation time, intraoperative blood loss, frequency of intraoperative fluoroscopy, incision length, incidence of postoperative deep vein thrombosis of lower extremity, pain visual analogue scale (VAS) score at 1 week after operation, and Harris score of hip joint at 3 months after operation were recorded and compared. X-ray re-examination was taken to check the quality of fracture reduction, fracture healing, and the shortening length of the femoral neck at 3 months after operation, and the incidences of internal fixation failure and osteonecrosis of the femoral head during operation. Results Compared with the control group, the operation time, intraoperative blood loss, and frequency of intraoperative fluoroscopy reduced in the two plate groups, and the quality of fracture reduction was better, but the incision was longer, and the differences were significant (P<0.05). The operation time and intraoperative blood loss were significantly higher in the traditional plate group than in the mortise-tenon joint plate group (P<0.05), the incision was significantly longer (P<0.05); and the difference in fracture reduction quality and the frequency of intraoperative fluoroscopy was not significant between two plate groups (P>0.05). There was 1 case of deep vein thrombosis of lower extremity in the traditional plate group and 1 case in the control group, while there was no thrombosis in the mortise-tenon joint plate group. There was no significant difference in the incidence between groups (P>0.05). All patients were followed up 12-15 months (mean, 13 months). There was no significant difference in VAS score at 1 week and Harris score at 3 months between groups (P>0.05). Compared with the control group, the fracture healing time and the length of femoral neck shortening at 3 months after operation were significantly shorter in the two plate groups (P<0.05). There was no significant difference between the two plate groups (P>0.05). There was no significant difference in the incidences of non-union fractures, osteonecrosis of the femoral head, or internal fixation failure between groups (P>0.05). Conclusion For Pauwels type Ⅲ femoral neck fractures, the use of 3D printed guide plate assisted reduction and fixation can shorten the fracture healing time, reduce the incidence of postoperative complications, and be more conducive to the early functional exercise of the affected limb. Compared with the traditional guide plate, the mortise-tenon joint plate can reduce the intraoperative bleeding and shorten the operation time.

  • Effectiveness analysis of surgical treatment of ipsilateral femoral neck fracture and subtrochanteric fracture

    Objective To discuss the effectiveness of intramedullary nail fixation with selective cable wiring in the treatment of ipsilateral femoral neck fracture and subtrochanteric fracture. Methods Between June 2012 and December 2015, a total of 19 patients with ipsilateral femoral neck fracture and subtrochanteric fracture underwent closed reduction of femoral neck fracture and intramedullary nail fixation combined with selective cable wiring. There were 5 males and 14 females with a median age of 52 years (range, 35-77 years). The cause of injury included traffic accident injury in 17 cases and falling injury in 2 cases. According to Garden classification for femoral neck fractures, 7 cases were rated as type Ⅱ, 8 as type Ⅲ, and 4 as type Ⅳ. Femoral subtrochanteric fractures were classified by Seinsheimer classification, with 9 cases as type Ⅱ, 5 as type Ⅲ, 3 as type Ⅳ, and 2 as type V. The interval from injury to operation ranged from 2 to 7 days with an average of 3.7 days. Results The operation time was 58-125 minutes (mean, 82.4 minutes) and the intraoperative blood loss was 225-725 mL (mean, 289.5 mL). All incisions achieved healing by first intention and no early complication such as infection was observed. All patients were followed up 12-18 months (mean, 13.9 months). At 1 month after operation, the tip apex distance was 9-23 mm (mean, 15.2 mm). All patients achieved bone union with the healing time of 18-42 weeks (mean, 27.4 weeks). One case of hip varus and femoral neck re-displacement (femoral neck shaft angle was 122°) occurred at 3 months after operation, which achieved bone union at 42 weeks after operation. Five patients complained of postoperative pain with the visual analogue scale (VAS) score of 1-3 (mean, 1.8), which did not influence normal life. A total of 16 patients recovered preoperative hip function. During follow-up, no fracture nonunion, femoral head necrosis, implant failure, screw cut-out, and loosening of cable wiring was observed. The Harris hip score (HSS) was 72-92 (mean, 82.8) at last follow-up and 15 patients (78.9%) achieved good hip function. Conclusion Intramedullary nail fixation combined with selective cable wiring was effective in the treatment of ipsilateral femoral neck fracture and subtrochanteric fracture.

  • Comparison of effectiveness of two cannulated screw configurations in the treatment of femoral neck fractures in young adults

    ObjectiveTo investigate and analyze the effectiveness of internal fixation with the two different cannulated screw implanting methods of rhomboid and inverted triangle in the treatment of femoral neck fracture in young adults.MethodsThe clinical data of 38 young adults with femoral neck fracture who met the selection criteria between January 2018 and August 2019 were retrospectively analyzed. According to the different methods of cannulated screw implanting, the patients were divided into two groups, 19 cases in each group. The trial group was treated with closed reduction and cannulated screw rhombic distribution internal fixation, while the control group was treated with closed reduction and cannulated screw inverted triangular distribution internal fixation. There was no significant differences in patients’ gender, age, cause of injury, Garden classification of fracture, and time from injury to operation between the two groups (P>0.05). The fracture healing time, the incidence of nonunion, femoral neck shortening, and femoral head necrosis were recorded and compared between the two groups; the effectiveness was evaluated by Harris score and visual analogue scale (VAS) score at last follow-up.ResultsThe incisions of the two groups healed by first intention. All patients were followed up 12-24 months with an average of 15.5 months. There were 1 case of fracture nonunion and 2 cases of shortening of femoral neck in the trial group; while there were 2 cases of fracture nonunion, 1 case of necrosis of femoral head, and 6 cases of femoral neck shortening in the control group; the difference in the incidence of complications (15.8% vs. 47.4%) between the two groups was significant (χ2=4.385, P=0.036). The remaining 18 cases in the trial group and 17 cases in the control group all achieved osteonal union, and the healing time was (14.8±1.6) weeks and (15.9±1.3) weeks, respectively, showing no significant difference between the two groups (t=1.265, P=0.214). At last follow-up, Harris score and VAS score of the trial group were 88.9±4.3 and 1.1±0.7, respectively, while those of the control group were 86.9±5.9 and 1.3±0.9, respectively, showing no significant difference (t=0.603, P=0.550; t=1.152, P=0.257). Hip function was evaluated in accordance with Harris score, the results were excellent in 12 cases, good in 6 cases, and fair in 1 case in the trial group, the excellent and good rate was 94.74%; the results were excellent in 10 cases, good in 7 cases, and fair in 2 cases in the control group, the excellent and good rate was 89.47%; there was no significant difference in the excellent and good rate between the two groups (χ2=0.368, P=0.544).ConclusionThe short-term effectiveness of the two kinds of cannulated screw implanting methods is clear, rhomboid fixation of 4 screws has strong stability with stress distribution, which can effectively reduce the incidence of femoral neck shortening, fracture nonunion, femoral head necrosis, and other complications.

  • Short-term clinical efficacy of secondary total hip arthroplasty after failure of internal fixation versus primary total hip arthroplasty in elderly patients with displaced femoral neck fracture

    Objective To compare the short-term clinical outcomes of secondary total hip arthroplasty (THA) after failure of internal fixation with primary THA in elderly patients with displaced femoral neck fractures, and explore the best treatment for displaced femoral neck fractures in the elderly. Methods A total of 300 elderly patients with displaced femoral neck fractures from January 2011 to January 2015 were retrospectively enrolled in this study, of whom 150 underwent primary THA and 150 underwent secondary THA after failure of internal fixation. The operation time, intraoperative bleeding volume, postoperative drainage volume, postoperative ambulation time, length of postoperative hospitalization, incidence of postoperative complications, and score of postoperative hip joint function were compared between the two groups. Results Compared with those in the secondary THA group, in the primary THA group, the operation time was shorter [(54.7±15.3) vs. (70.1±23.4) minutes], the intraoperative bleeding volume was less [(116.9±35.0) vs. (131.7±44.5) mL], the postoperative ambulation was earlier [(1.0±0.3) vs. (1.8±0.6) days], the length of postoperative hospitalization was shorter [(12.0±2.9) vs. (15.2±3.1) days], and the differences were all statistically significant (P<0.05); but there was no statistically significant difference in the incidence of postoperative complications or the Harris scores at 3, 6, 12, and 24 months after operation (P>0.05). Conclusion The secondary THA for femoral neck fracture is more difficult, with longer stay in hospital, but the short-term clinical efficacy is similar to that of the primary THA.

  • Patterns and research progress on the concomitant ipsilateral fractures of intracapsular femoral neck and extracapsular trochanter

    ObjectiveTo summarize the patterns and research progress of the concomitant ipsilateral fractures of intracapsular femoral neck and extracapsular trochanter, and to provide a common language among orthopedic surgeons for scientific exchange.MethodsAccording to related literature and authors own experiences concerning the anatomic border between femoral neck and trochanter region, the intertrochanteric line (or intertrochanteric belt) and its capsularligament attachment footprint, fracture patterns, and treatment strategies were reviewed and analyzed.ResultsWith the rapid growing of geriatric hip fractures, an increased incidence was noted in recent years regarding the proximal femoral comminuted fractures that involving ipsilateral intracapsular neck and extracapsular trochanter regions simultaneously. But the concept of femoral neck combined with trochanter fractures was ambiguous. Based on the anatomic type of femoral neck fracture, the location of fracture center, and the ability to achieve direct inferior calcar or anteromedial cortex-to-cortex apposition and buttress, we classified these complex fractures into 3 sub-types: ① Segmental femoral neck fractures (two separate fracture centers at subcapital and trochanteric region respectively); ② Femoral neck fracture (trans-cervical) with extension to the supero-lateral trochanteric region (fracture center in femoral neck); ③ Trochanteric fracture with extension to the medio-inferior femoral neck region (fracture center in trochanter, comminuted basicervical fracture, or variant type of comminuted trochanter fracture). For treatment strategy, surgeons should consider the unique characteristics of femoral neck and trochanter, usually with combined fixation techniques, or arthroplasty supplemented with fixation.ConclusionCurrently there is no consensus on diagnosis and terminology regarding the concomitant ipsilateral fractures of femoral neck and trochanter. Further studies are needed.

  • COMPARISON OF CANNULATED SCREWS FIXATION WITH DIFFERENT REDUCTION METHODS AT DIFFERENT TIME POINTS FOR DISPLACED FEMORAL NECK FRACTURES IN TERMS OF FRACTURE HEALING

    Objective To compare the therapeutic effect of cannulated screws fixation at different time points through different reduction methods on the heal ing of displaced femoral neck fractures. Methods From January 1997 to September 2007, 240 patients with displaced femoral neck fracture were treated, including 121 males and 119 females aged 22-79 years old (average 56 years old). All cases were fresh and close fractures. According to the fractured part, there were 133cases of subcapital fracture, 64 of transcervical fracture and 43 of basal fracture. According to Garden classification, there were 105 cases of type III and 135 of type IV. Cannulated screws fixation was performed on all the patients, and the time from injury to operation was 6 hours to 7 days. Fifty-five cases received closed reduction and 59 cases received l imited open reduction as emergency treatment, while 65 cases received closed reduction and 61 cases received l imited open reduction as selective operation. Different groups were compared in terms of the heal ing rate of fracture, the excellent and good rate of reduction as well as the excellent and good rate of fixation. Results There was no significant difference between the closed reduction and the l imited open reduction in terms of operation time and bleeding volume (P gt; 0.05). Postoperatively, all wounds healed by first intention, no infection was observed, avascular necrosis of femoral head occurred in 44 cases, and the rate of avascular necrosis of femoral head in the l imited open reduction at emergency group was less than that of other 3 groups (P lt; 0.01). All the patients were followed up for 12-72 months (average 38 months), 193 cases got fracture heal ing at 10-23 months after operation (average 14 months). For the closed reduction as emergency operation group, the l imited open reduction as emergency operation group, the closed reduction as selective operation group, and the l imited open reduction as selective operation group, the heal ing rate of fracture was 74.55%, 91.53%, 69.23% and 86.89%, respectively; the excellent and good rate of reduction was 73.73%, 94.92%,70.77% and 91.80%, respectively; the excellent and good rate of fixation was 76.36%, 93.22%, 73.85% and 88.52%, respectively. The heal ing rate of fracture, the excellent and good rate of reduction as well as the excellent and good rate of fixation in the l imited open groups were higher than that of the closed reduction groups (Plt; 0.01), and there was no significant difference between the emergency operation groups and the selective operational groups (Pgt; 0.05). Conclusion The reduction methods have significant influences on the heal ing of fractures after cannulated screws fixation of the displaced femoral neck fracture, and the operation time has no obvious effect on fracture heal ing.

  • Comparison of effectiveness of femoral neck system and cannulate compression screw in treatment of femoral neck fracture in young and middle-aged patients

    ObjectiveTo compare the effectiveness of femoral neck system (FNS) and cannulate compression screw (CCS) in the treatment of femoral neck fractures in young and middle-aged patients. MethodsThe clinical data of 82 young and middle-aged patients with femoral neck fracture treated between January 2018 and September 2020 were retrospectively analyzed. They were divided into FNS group (24 cases) and CCS group (58 cases) according to different surgical methods. There was no significant difference between the two groups (P>0.05) in general data such as gender, age, height, body mass, cause of injury, complications, fracture location, and fracture classification (Garden classification and Pauwells classification). The operation time, intraoperative blood loss, complications (nonunion, osteonecrosis of the femoral head, shortening of femoral neck, etc.), visual analogue scale (VAS) score at 2 days after operation, clinical healing time of fracture, and Harris score of hip joint after operation were recorded and compared between the two groups. ResultsThe operation time and VAS score at 2 days after operation in FNS group were significantly lower than those in CCS group (P<0.05); there was no significant difference in intraoperative blood loss between the two groups (t=0.263, P=0.796). The patients in CCS group were followed up 6-18 months, with an average of 13.6 months; and the follow-up time in FNS group was 3-12 months, with an average of 7.3 months. There was no complication of internal fixator loosening in both groups. There were 2 cases of osteonecrosis of the femoral head, 1 case of bone nonunion, and 13 cases of femoral neck shortening in CCS group and only 2 cases of femoral neck shortening in FNS group. The difference in the incidence of complications between the two groups (27.6% vs. 8.3%) was significant (χ2=36.670, P=0.015). In CCS group, 3 cases underwent secondary artificial hip arthroplasty due to bone nonunion and osteonecrosis of the femoral head, and the remaining 55 cases achieved clinical healing; in FNS group, 6 patients excluded in the statistics because the follow-up time was less than 6 months, and the remaining 18 fractures healed clinically; there was significant difference in fracture healing time between the two groups (t=4.481, P=0.000). The difference of Harris score of hip joint between 9 months and 6 months after operation in FNS group was significantly higher than that in CCS group (P<0.05), and the Harris score at 9 months after operation was significantly higher than that at 6 months after operation in both groups (P<0.05). ConclusionFNS can accelerate the healing of femoral neck fractures in young and middle-aged patients, so that patients can start functional exercise as soon as possible, thereby reducing the incidence of related complications.

  • Comparison of effectiveness of three surgical methods in treatment of Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients

    Objective To compare the effectiveness of three surgical methods in the treatment of Pauwels type Ⅲ femoral neck fracture in young and middle-aged patients, in order to provide reference for clinical selection of appropriate surgical methods. Methods The clinical data of 103 patients with Pauwels type Ⅲ femoral neck fracture who met the selection criteria between June 2018 and December 2021 were retrospectively analyzed. The fractures were fixed with hollow screws in an inverted triangular shape (37 cases, hollow screw group), hollow screws in an inverted triangular shape combined with eccentric shaft screw (34 cases, eccentric shaft screw group), and hollow screws in an inverted triangular shape combined with medial support plate (32 cases, support plate group). There was no significant difference in age, gender, cause of injury, body mass index, time from injury to operation, side of the fracture, and Garden classification, whether they were in traction preoperatively, and other baseline data between groups (P>0.05). The operation time, intraoperative blood loss, the number of fluoroscopy, the length of hospital stay, early postoperative complication and postoperative weight-bearing time of the three groups were recorded. Harris score was used to evaluate joint function at 6 and 12 months after operation, and the difference between the two time points (change value) was calculated for comparison between groups. X-ray films were reviewed to evaluate the quality of fracture reduction (Garden index) and healing, as well as the occurrence of internal fixation failure and femoral head necrosis. Results The patients of the three groups were successfully completed. Compared with the hollow screw group and the eccentric shaft screw group, the operation time and intraoperative blood loss of the support plate group significantly increased, the number of fluoroscopy reduced, and the quality of fracture reduction was better, the differences were significant (P<0.05 ). The operation time, intraoperative blood loss, and the number of fluoroscopy of the hollow screw group were less than those of the eccentric shaft screw group, the differences were significant (P<0.05). There was no significant difference in the length of hospital stay between groups (P>0.05). All patients in the three groups were followed up 21-52 months, with an average follow-up time of 36.0 months, and there was no significant difference between groups (P>0.05). The incisions of all patients healed by first intention. Imaging reexamination showed that there was no significant difference in the incidence of fracture nonunion between groups (P>0.05). The fracture healing, partial weight-bearing, and full weight-bearing were significantly earlier in the eccentric shaft screw group and the support plate group than in the hollow screw group (P<0.05). There was no significant difference in change value of Harris score, the incidence of postoperative deep venous thrombosis and femoral head necrosis between groups (P>0.05); however, the incidence of internal fixation failure in the support plate group and the eccentric shaft screw group was significantly lower than that in the hollow screw group (P<0.05). The incidence of postoperative lateral thigh irritation in the support plate group was significantly lower than that in the hollow screw group (P<0.05); there was no significant difference between the eccentric shaft screw group and the other two groups (P>0.05). The overall incidences of postoperative complications in the eccentric shaft screw group and the support plate group were significantly lower than that in the hollow screw group (P<0.05). Conclusion For young and middle-aged patients with Pauwels type Ⅲ femoral neck fracture, compared with simple hollow screw fixation in an inverted triangular shape, combined with medial support plate or eccentric shaft screw internal fixation can shorten the fracture healing time, reduce the incidences of postoperative complication, more conducive to early functional exercise of the affected limb; at the same time, the operation time and blood loss of combined eccentric shaft screw internal fixation are less than those of combined medial support plate internal fixation, so the hollow screw in an inverted triangular shape combined with eccentric shaft screw fixation may be a better choice.
