ABSTRACT

Objective:To investigate the clinical efficacy of proximal femoral nail anti-rotation (PFNA) assisted by the "3-2-1" surface positioning method in the treatment of femoral subtrochanteric fractures.Methods:A total of 97 patients with subtrochanteric fractures admitted to the Second Hospital of Fuzhou from January 2015 to December 2020 were retrospectively analyzed. They were divided into two groups according to whether the "3-2-1" surface positioning method (3 longitudinal axes, 2 preset incisions, and 1 auxiliary incision) was used. There were 44 patients in the surface positioning group, including 25 males and 19 females, aged 61.59±18.43 years (range, 22-90 years). According to the Seinsheimer classification, there were 13 cases of type II, 11 cases of type III, 6 cases of type IV, and 14 cases of type V. The mechanism of injury was low energy injury in 26 cases and high energy injury in 18 cases. There were 53 patients in the traditional positioning group, including 30 males and 20 females, aged 56.38±17.24 years (range, 24-90 years). According to the Seinsheimer classification, there were 9 cases of type II, 22 cases of type III, 9 cases of type IV, and 13 cases of type V. According to the mechanism of injury, there were 30 cases of low energy injury and 23 cases of high energy injury. The length of incision, operation time, and blood loss were recorded. At 1, 3, 6, and 12 months after operation, the anteroposterior and lateral X-ray films of the hip were taken to evaluate the imaging indicators (neck-shaft angle, anteroposterior and lateral displacement, and angulation), fracture healing, and complications (infection, malunion, loosening and breakage of the internal fixation, and periprosthetic fracture). The Harris hip score and EuroQol five dimensions questionnaire (EQ-5D) were evaluated.Results:All patients successfully completed the operation and were followed up for 15.12±1.54 months (range, 12-18 months). The operation time, incision length, dominant blood loss and hidden blood loss in the surface positioning group were 1.78(1.50, 2.00) h, 8(8, 9) cm, 300(200, 400) ml and 843(629, 1 130) ml, respectively, which were less than 2.10(1.69, 2.38) h, 10(9, 12) cm, 400(300, 500) ml and 1 030(954, 1 266) ml in the traditional positioning group, and the difference was statistically significant ( P<0.05). The neck-shaft angle in the surface positioning group was 135.54°±2.83°, which was larger than 132.33°±3.37° in the traditional positioning group, and the difference was statistically significant ( t=5.02, P<0.001). The anterolateral and lateral displacement and lateral image angle in the surface positioning group were 4.70±1.60 cm, 4.52±1.71 cm and 9.36°±2.94°, respectively, which were lower than 6.14±2.57 cm, 5.98±2.70 cm and 11.46°±4.68° in the traditional positioning group, and the difference was statistically significant ( P<0.05). One year after operation, the Harris hip score and EQ-5D score of the surface positioning group were 92(84, 99) points and 0.90(0.73, 1.00) points, respectively, which were higher than 88(74, 96) points and 0.81(0.72, 0.94) points of the traditional positioning group ( P<0.05). Conclusion:The "3-2-1" surface positioning method assisted PFNA internal fixation in the treatment of femoral subtrochanteric fracture can improve the quality of reduction, reduce intraoperative blood loss, and improve hip function and quality of life.

ABSTRACT

Objective:To compare the short-term effects of proximal femoral bionic nail (PFBN) and proximal femoral nail antirotation (PFNA) in the treatment of intertrochanteric fracture.Methods:Retrospectively analyzed were the data of 56 patients with intertrochanteric fracture of the femur who had been admitted to Department of Orthopedic Trauma, The People's Hospital of Juye County and Trauma Center, Central Hospital Affiliated to The First Medical University of Shandong from August 2020 to April 2022. The patients were divided into 2 even groups according to their internal fixation methods ( n=28). In the PFBN fixation group, there were 12 males and 16 females with an age of (70.4±7.8) years; by AO classification, there were 4 cases of type 31-A1, 16 cases of type 31-A2, and 8 cases of type 31-A3. In the PFNA fixation group, there were 10 males and 18 females with an age of (73.0±8.9) years; by AO classification, there were 2 cases of type 31-A1, 16 cases of type 31-A2, and 10 cases of type 31-A3. The operation time, intraoperative blood loss, fracture reduction, fracture healing time, Harris hip score, and complications were compared between the 2 groups. Results:There was no statistically significant difference between the 2 groups in the preoperative general data, showing comparability ( P>0.05). The follow-up time was (7.3±0.9) months for the PFBN group and (7.4±1.1) months for the PFNA group, showing no significant difference ( P>0.05). There was no significant difference either between the 2 groups in operation time, intraoperative blood loss or quality of fracture reduction ( P>0.05). The PFNA group had significantly shorter fracture healing time [(3.9±0.9) months] than the PFNA group [(4.7±1.1) months], and a significantly higher Harris hip score at the last follow-up [(83.9±4.3) points] than the PFNA group [(81.0±3.4) points] (both P<0.05). Fixation failed in one patient in the PFNA group due to cut-out of the head and neck screws while no complications were observed in the PFBN group. Conclusion:In the treatment of intertrochanteric fracture of the femur, PFBN fixation may result in stronger fixation to effectively avoid cut-out of the head and neck screws, and faster fracture healing and functional recovery of the hip than PFNA fixation.

ABSTRACT

Objective:To explore the clinical efficacy of a retrograde pubic ramus intramedullary nail (RPRIN) in the treatment of anterior pelvic ring fractures.Methods:A retrospective study was conducted to analyze the 14 patients with anterior pelvic ring fracture who had been treated and followed up at Department of Traumatic Surgery, Tongji Hospital From June 2020 to February 2021. There were 10 males and 4 females with an age of (44.8±12.5) years. By the AO/OTA classification for pelvic fractures, 5 cases were type 61-A, 4 cases 61-B, and 5 cases type 61-C; by the Nakatani classification, 1 case belonged to unilateral zone Ⅰ fracture, 5 cases to unilateral zone Ⅱ fracture, 2 cases to unilateral zone Ⅲ fracture, 3 cases to right zone Ⅱ and left zone Ⅲ fracture, 2 cases to zone Ⅲ fracture on both left and right sides, and 1 case to zone Ⅱ fracture on both sides. The time from injury to operation was (7.8±1.8) days. All the anterior pelvic ring fractures were fixated with a RPRIN. The time and fluoroscopic frequency for placement of every single RPRIN, quality of fracture reduction, and pelvic function and incidence of postoperative complications at the last follow-up were recorded.Results:A total of 18 RPRINs were placed in the 14 patients. For placement of each RPRIN, the time was (35.9±8.6) min, and the fluoroscopic frequency (22.8±1.9) times. No complications such as infection occurred at any surgical incision after RPRIN placement. According to the Matta scoring, the quality of postoperative fracture reduction was assessed as excellent in 7 cases, as good in 5 cases and as fair in 2 cases. The 14 patients were followed up for (18.1+1.5) months. Their X-ray and CT images of the pelvis at the last follow-up showed that the fractures healed well and the intramedullary nails were placed in the cortical bone of the anterior ring of the pelvis. According to the Majeed scoring at the last follow-up, the pelvic function was assessed as excellent in 10 cases, as good in 3 cases and as fair in 1 case. One patient reported discomfort during squatting 2 months after operation but the symptom improved 3 months later without any special treatment. No patient experienced such complications as displacement or slippage of RPRIN, or pain at the insertion site.Conclusion:RPRIN is effective in the treatment of anterior pelvic ring fractures, showing advantages of small surgical incision, limited intraoperative fluoroscopy and short operation time.

ABSTRACT

Surgical intervention is the first choice treatment for intertrochanteric fractures that are common in clinical practice. Cephalomedullary nailing with two parts inserted respectively into the femoral medullary cavity and femoral head has been the mainstream protocols for the elderly patients with intertrochanteric fracture, but insertion of the cephalomedullary nail may likely lead to the outward displacement of the femoral shaft and the inversion and rotation of the head and neck bone mass, namely the so-called wedge effect. However, few reports have dealt with how to prevent the wedge effect and reduce the complications it may cause such as coxa vara deformity. The present review expounds and analyzes the concept, biomechanical mechanism, influencing factors, measurements, and prevention methods of the wedge effect, hoping to help the surgeons who try to avoid the wedge effect in surgical treatment.

ABSTRACT

Objective:To investigate the efficacy of a proximal femoral locking plate (LPFP) versus a proximal femoral anti-rotation intramedullary nail (PFNA) in the treatment of femoral intertrochanteric fractures in older adult patients. Methods:A total of 130 older adult patients with femoral intertrochanteric fractures who received treatment in Linghu People's Hospital of Huzhou from May 2017 to June 2020 were included in this study. They were randomly assigned to undergo treatment with either a PFNA (observation group, n = 65) or an LPFP (control group, n = 65). Intraoperative blood loss, incision length, operative time, and time to fracture healing were determined in each group. At 1, 3, and 6 months after surgery, the Harris hip score was used to evaluate hip joint recovery. Coxa vara, incision infection, and internal fixation loosening were compared between the two groups. Results:Intraoperative blood loss in the observation group was less than that in the control group [(189.26 ± 48.15) mL vs. (96.47 ± 40.21) mL, t = -11.93, P < 0.001]. Incision length, operative time, and time to fracture healing in the observation group were significantly shorter than those in the control group [(4.03 ± 1.48) cm vs. (12.16 ± 1.55) cm, (72.13 ± 28.75) minutes vs. (120.34 ± 29.01) minutes, (9.89 ± 1.52) weeks vs. (13.63 ± 1.74) weeks, t = -30.59, -9.52, -13.05, all P < 0.001]. At 1 month after surgery, there was no significant difference in Harris hip score between the two groups ( t = 1.28, P > 0.05). At 3 and 6 months after surgery, the Harris hip score gradually increased in the control and observation groups ( F = 13.44, 8.26, both P < 0.001). At 3 and 6 months after surgery, Harris hip scores in the observation group were significantly higher than those in the control group [(85.17 ± 4.29) points vs. (79.50 ± 4.12) points, (95.30 ± 1.04) points vs. (87.69 ± 1.25) points, t = 7.69, 37.73, both P < 0.001]. The incidence of complications in the observation group was significantly lower than that in the control group [1.54% (1/65) vs. 10.77% (7/65), χ2 = 4.80, P = 0.029). Conclusion:Compared with LPFP, PFNA can effectively reduce intraoperative blood loss in older adult patients with femoral intertrochanteric fractures, accelerate the progress of fracture healing, promote the recovery of the hip joint, and has fewer complications. Therefore, PFNA is worthy of popularization.

ABSTRACT

ABSTRACT Introduction: Metacarpal fractures are common and can be treated surgically using Kirschner wires (K-wires) or intramedullary fixation with compression screws (IMCS). Objectives: Analyze the postsurgical results from treating the metacarpal extra-articular fractures through the retrograde Kirschner wire technique, and compare it with the intramedullary compression screw fixation. Methods: Retrospective and quantitative studies were to analyze patients' medical records, and a postsurgical evaluation questionnaire was given to the patients, who were divided into K-wire and IMCS. Results: The period of immobilization with a splint took six weeks for the K-wire group and four weeks for the IMCS group. The average time for consolidation took, respectively, fifty-seven days and forty-seven days. The first group could restart their activities twenty-two days after the other, and the average force value of the treated hand, when compared with its contralateral, was 93.9% and 95.4%, respectively. Between the operated hand and its contralateral, there was a difference of 16° in the total measures of the metacarpophalangeal and interphalangeal joint's range of movement among the K-wire group and 5° among the IMCS group. Conclusion: The patients who participated in this study showed excellent results after surgery, and both treatments were proven to be safe and reliable. Evidence level III; Retrospective comparative study .

ABSTRACT

ABSTRACT Objective Evaluate the stability provided by two flexible intramedullary nails (FINs) in a simulation of fractures at the proximal levels in pediatric femur models. Methods Two FINs were inserted in 18 synthetic models of pediatric femurs. Fractures were simulated at one of three levels, and the models were divided into the following groups (n=6): diaphysis (control), subtrochanteric and trochanteric. Flex-compression tests were performed with force up to 85 N. Relative stiffness and the average deformation was obtained. Torsion tests were performed by rotating the proximal fragment until 20°, to obtain the average torque. Results At flex-compression, the set's average relative stiffness and average deformations were: 54.360x103 N/m and 1.645 mm in the control group, respectively. In the subtrochanteric group, the relative stiffness was 31.415x103 N/m (-42.2%) and the deformation was 2.424 mm (+47.3%) (p<0.05). For the trochanteric group, the relative stiffness was 30.912x103 N/m (+43.1%) and the deformation was 2.508 mm (+52.4%) (p<0.05). In torsion, the average torque was 1.410 Nm in the control group; 1.116 Nm in the subtrochanteric group (-20.8%), and 2.194 Nm in the trochanteric group (+55.6%) (p<0.05). Conclusion FINs do not seem to be biomechanically competent for the treatment of proximal femoral fractures. Level of Evidence I; Therapeutic Studies - Investigating the results of treatment.

ABSTRACT

Objective:To investigate the clinical results of Bouquet technique [multiple elastic stable intramedullary nails (ESIN)] in the treatment of unstable pediatric femoral shaft fractures.Methods:From August 2016 to October 2019, 25 pediatric patients (26 sides) with unstable femoral shaft fracture were treated with Bouquet technique at Department of Pediatric Orthopedics, The Second Fuzhou Hospital Affiliated to Xiamen University. They were 17 boys and 8 girls, with a mean age of 7.8 years at injury (from 5 to 11 years). Their body weight ranged from 23 kg to 62 kg, with an average of 36.3 kg. Long oblique fractures happened in 6 cases (6 sides) and comminuted fractures in 19 cases (20 sides). Ten cases (11 sides) were fixated with 3 ESINs (type 3A) and 15 cases (15 sides) with 4 ESINs (type 4A in 6 cases and type 2A+2B in 9 cases). The multiple ESINs were inserted from the medial and lateral cortex of the distal femur through the fracture sides until the head ends of the nails were distributed evenly at the proximal femur. Recorded were the fracture healing time, complications, fracture reduction quality and hip function at the last follow-up.Results:All the 25 patients were followed up for 18 to 27 months (mean, 22.4 months). Their fractures got united after 4 to 8 weeks (mean, 6.3 weeks). One case presented with femoral overgrowth of 1.1 cm and another case with nail tail irritation. Follow-ups revealed that none of the patients had such complications as incision infection, limited joint movement, nonunion or delayed fracture union. The limb alignment recovered well with no angulation, shortening or rotational deformity. At the last follow-up, according to the efficacy evaluation system for intramedullary nails by Flynn et al., the quality of reduction of femoral shaft fractures was assessed as excellent in 24 sides and as good in 2 sides, giving an excellent and good rate of 100% (26/26). According to the hip Harris scoring system, the hip function was assessed as excellent in all the 26 sides, giving an excellent rate of 100% (26/26).Conclusion:Bouquet technique is safe and effective in the treatment of unstable pediatric femoral shaft fractures, leading to fine clinical results.

ABSTRACT

Objective:To compare the efficacy of double thread elastic locking intramedullary nail (ELIN) and threaded elastic intramedullary nail (TEIN) in the treatment of mid-shaft clavicular fracture.Methods:From August 2017 to September 2020, 33 patients with mid-shaft clavicular fractures were treated with ELIN (double threaded nail group), including 14 males and 19 females, age 52.09±16.32 years old; Robinson classification: 20 cases of type 2A2, 6 cases of type 2B1, and 7 cases of type 2B2. Thirty-two patients were selected as the control group with TEIN fixation (single threaded nail group) during the same period, including 13 males and 19 females; age 43.25±15.03 years old; Robinson classification: 19 cases of type 2A2 and 5 cases of type 2B1, 8 cases of 2B2 type. The operation time, intraoperative incision length, fracture healing time, internal fixation removal time, Constant-Murley shoulder joint score, disabilities of the arm, shoulder, and hand (DASH) score, fracture reduction and postoperative complications were compared between the two groups.Results:The patients in both groups were followed up after operation, the double-threaded screw group was followed up for 16-48 weeks (average, 23.7 weeks), and the single threaded nail group was followed up for 15-51 weeks (average, 22.9 weeks). The operation time of the double threaded nail group and the single threaded nail group were 19.45±6.74 min and 19.59±4.98 min, and the length of the incision was 1.70±0.79 cm and 1.73±0.84 cm. The fracture healing time were 12.12±1.29 weeks and 13.88±1.84 weeks. The internal fixation removal time was 13.09±1.31 weeks and 15.69±1.94 weeks. The Constant-Murley shoulder score was 93.18±3.78 points and 90.09±4.03 points, and the DASH scores were 1.49± 0.49 points and 3.85±1.13 points; There was no significant difference in operation time and incision length between the two groups ( t=0.01, 0.19; P>0.05), while fracture healing ( t=3.70, P<0.001), internal fixation removal time ( t=6.34, P<0.001), Constant-Murley shoulder score ( t=3.19, P<0.001), DASH score ( t=10.95, P<0.001) differences were statistically significant. The length of the clavicle on the healthy side was 16.38±1.09 cm in the double threaded nail group, and the length of the clavicle on the affected side after internal fixation removal was 16.33±1.12 cm. There was no obvious shortening deformity on the affected side, and there was no significant difference in the length of the clavicle between the two sides ( t=1.57, P=0.127). The clavicle lengths of the healthy side and the affected side after internal fixation removal in the single threaded nail group were 16.55±1.12 cm and 15.12±1.18 cm, and the difference was statistically significant ( t=8.02, P<0.001). The postoperative shortening values of the double-threaded screw group and the single-threaded screw group were 9.47±2.12 mm and 17.41±2.42 mm, and the difference was statistically significant ( t=14.07, P<0.001). Postoperatively, 5 cases of bursitis and 2 cases of skin irritation occurred in the double threaded nail group; While 6 cases of bursitis, 3 cases of skin irritation, 4 cases of shortening malunion, and 1 case of broken nail occurred in the single threaded nail group (fracture delayed union after replacement of internal fixation); the other patients did not experience screw retraction, wound infection, delayed fracture union or nonunion, neurovascular injury, and achieved osseous union. Conclusion:Both elastic intramedullary nails are effective surgical methods for the treatment of middle clavicle fractures, and the operation time is short and minimally invasive. However, compared with the TEIN, the fracture healing time of the double-threaded ELIN is shorter, the internal fixation removal time is earlier, the shoulder joint and upper limb function is better, and the shortening deformity is less likely to occur.

ABSTRACT

Objective:To investigate the efficacy of elastic locking intramedullary nail (ELIN) in the treatment of mid clavicle fractures.Methods:From January 2014 to December 2020, the data of 61 patients with mid-clavicle fracture treated with ELIN were retrospectively analyzed. Among them, 38 patients were from the Fourth Central Hospital Affiliated to Nankai University and 23 were from the Second People's Hospital of Hulunbuir City. There were 36 males and 25 females, aged from 19 to 85 years (average, 54.5 years), 39 cases on the left side and 22 cases on the right side. According to Robinson's classification, there were 20 cases of type 2A2, 29 cases of type 2B1 and 12 cases of type 2B2. There was no nerve or vascular injury before operation. The postoperative evaluation measures included incision length, operation time, blood loss, fracture reduction, fracture healing time, ELIN removal time, shoulder Constant-Murley score, disabilities of the arm, shoulder, and hand (DASH) score, and related complications.Results:All patients were followed up for 13-51 weeks (average, 21.8 weeks). There were 34 cases of closed reduction and 27 cases of mini-open reduction, and the length of incision was 2.04±1.08 cm. The closed reduction operation time was 20.32±7.11 min, and the mini-open reduction operation time was 20.30±5.37 min. The intraoperative blood loss was 6.47±2.31 ml in the closed reduction group and 27.41±11.55 ml in the mini-open reduction group. Compared with the healthy side, the clavicle length of the affected side was shortened by 7.74%±3.51% of pre-operation and 0.71%±1.00% of post-operation, there was statistically significant difference in the length of clavicle shortening of pre- and post-operation ( t=3.84, P<0.001). The fracture healing time was 10.48±2.39 weeks. The removal time of ELIN was 13.39±2.69 weeks. At the last follow-up, the Constant-Murley score of shoulder joint was 98.87±1.74. The average of DASH score was 1.13 (range, 0-10). There were 18 cases of skin irritation after operation, of which 13 cases formed pressure sores at the tail end 3-6 weeks after the operation, and were treated with dressing change and keeping clean; 4 cases of skin irritation at the tail end formed bursitis, which disappeared after removal of the internal fixation. In 1 case, the tip of ELIN penetrated the anterior cortex from the proximal clavicle and stimulated the skin. Radiograms showed continuous callus at 4 weeks after operation, and there was no local tenderness on the physical examination, which reached the clinical healing standard, and the symptoms were relieved after the nail was removed. No serious complications such as neural and vascular injury, nail breaking, delayed healing, infection, numbness or discomfort in the subclavian area occurred in all cases, and all patients were satisfied or basically satisfied with the aesthetic of the skin appearance. Conclusion:Minimally invasive and microstress shielding fixation of mid-clavicle fracture with ELIN have the advantages of simple operation, minimally invasive, beautiful appearance, anti-short-shrinkage and rapid fracture healing etc. It is an effective surgical method for the treatment of mid-clavicle fractures.

ABSTRACT

Objective:To compare the short-term therapeutic effects of Gamma 3 U-Blade system and Gamma 3 nails in the treatment of elderly patients with osteoporotic unstable intertrochanteric fracture.Methods:The data of 70 elderly patients with osteoporotic unstable intertrochanteric fracture were retrospectively analyzed who had been admitted to the Department of Orthopedics, Wuhan Fourth Hospital from June 2018 to December 2020. They were divided into 2 groups according to their treatments. In the U-Blade group of 35 cases subjected to fixation with Gamma 3 U-Blade system, there were 14 males and 21 females with an age of (77.7 ± 4.8) years; in the Gamma 3 nail group of 35 cases subjected to fixation with Gamma 3 nails, there were 14 males and 21 females with an age of (79.3 ± 5.2) years. The 2 groups were compared in terms of operation time, intraoperative blood loss, apex distance, fracture union time, postoperative complications, timed up and go (TUG) at postoperative 2 weeks, 3 months and 6 months, and hip function at postoperative 9 months.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). There was no significant difference either in operation time, intraoperative blood loss or apex distance between the 2 groups ( P>0.05). The fracture union time [(12.0 ± 0.2) weeks] and Harris hip score at postoperative 9 months [90 (90, 91)] in the U-Blade group were insignificantly different from those in the Gamma 3 nail group [(12.0 ± 0.3) weeks and 91 (89, 91)] ( P>0.05). The rate of implant-related complications in the U-Blade group [0% (0/35)] was significantly lower than that in the Gamma 3 nail group [17.1% (6/35)] and the TUGs at postoperative 2 weeks and 3 months [(80.2 ± 3.6) s and 45 (43, 49) s] in the former were significantly shorter than those in the latter [(89.3 ± 4.2) s and 56 (54, 59) s] ( P<0.05). Conclusion:In the treatment of elderly patients with osteoporotic unstable intertrochanteric fracture, compared with traditional Gamma 3 nails, Gamma 3 U-Blade system can reduce implant-related complications and facilitate early recovery of walking ability.

ABSTRACT

Objective:To investigate the efficacy of proximal femoral intramedullary nail antirotation fixation in the treatment of intertrochanteric fracture of the femur and its effects on Harris hip scores.Methods:Sixty-eight patients with intertrochanteric fracture of the femur who received treatment in Cixi People's Hospital from April 2018 to October 2019 were included in this study. They were randomly assigned to receive dynamic hip screw fixation (control group, n = 34) or proximal femoral intramedullary nail antirotation fixation (observation group, n = 34). Clinical efficacy, Harris score, surgical indicators, and the incidence of complications were compared between the two groups. Results:The response rate was significantly higher in the observation group than in the control group [94.12% (32/34) vs. 76.47% (26/34), χ2 = 5.81, P < 0.05]. The excellent and good rate of hip function as evaluated by Harris hip scores was significantly higher in the observation group than in the control group [91.18% (31/34) vs. 73.53% (25/34), χ2 = 6.05, P < 0.05]. The operative time, blood loss, incision length, and fracture healing time in the observation group were (51.66 ± 10.52) minutes, (120.26 ± 12.29) mL, (8.09 ± 2.62) cm, and (9.86 ± 2.67) weeks respectively, and those in the control group were (78.32 ± 12.23) minutes, (238.45 ± 17.85) mL, (12.95 ± 3.29) cm, and (13.65 ± 3.46) weeks, respectively. There were significant differences in these indices between the two groups ( t = 14.55, 14.03, 14.85, 14.60, all P < 0.05). The incidence of complications was significantly lower in the observation group than in the control group [5.88% (2/34) vs. 23.53% (8/34), χ2 = 6.51, P < 0.05]. Conclusion:Proximal femoral intramedullary nail antirotation fixation is superior to dynamic hip screw fixation in the treatment of intertrochanteric fracture of the femur. The former increases Harris hip score, decreases the incidence of complications, and is of great clinical innovation.

ABSTRACT

Objective:To evaluate the effect of femoral stable interlocking intramedullary nail (FSIIN) and proximal femoral nail anti-rotation (PFNA) in the treatment of anterograde intertrochanteric fractures.Methods:From June 2015 to December 2020, 68 cases with surgically treated of femoral intertrochanteric fractures were included. Among them, there were 37 cases (17 males and 20 females) in proximal femoral nail antirotation (PFNA) group, and the age ranged from 48 to 78 years (62.9±7.1 years); 18 cases were on the left and 19 cases on the right; AO/OTA classification: 16 cases of A1 type and 21 cases of A2 type. And there were 31 cases (18 males and 13 females) in FSIIN group without distal locking, the age ranged from 47 to 84 years (62.4±8.6 years); 15 cases were on the left and 16 cases on the right; AO/OTA classification: 11 cases of A1 type and 20 cases of A2 type. Fracture fixation time, incision length and number, intraoperative blood loss, fracture healing time, visual analogue scale (VAS) and Harris scores at the last follow-up were compared between the two fixation methods.Results:Both groups were followed up, and the follow-up time was 15.3±3.9 months in the FSIIN group and 15.7±3.9 months in the PFNA group, and the difference was not statistically significant ( t=0.42, P=0.675). In FSIIN group, the fracture fixation time was 26.6±11.5 min, the total incision length was 7.6±1.8 cm, the intraoperative blood loss was 107.6±42.8 ml and the fracture healing time was 10.1±1.3 weeks. In PFNA group, the fracture fixation time was 40.3±10.8 min, the total incision length was 12.2±1.8 cm, the intraoperative blood loss was 209.4±52.0 ml and the fracture healing time was 16.3±1.6 weeks. In FSIIN group, the fracture fixation time ( t=3.46, P<0.001), total incision length ( t=2.39, P=0.020), intraoperative blood loss ( t=3.16, P<0.001), fracture healing time ( t=2.80, P<0.001) were all less than those in PFNA group, and the difference was statistically significant. The VAS score of FSIIN group was 1.4±0.5 points, and that of PFNA group was 1.6±0.6 points, and the difference was not statistically significant ( t=0.68, P=0.503). The Harris score was 84.5±2.2 in FSIIN group and 83.3±2.5 in PFNA group, and the difference was not statistically significant ( t=0.63, P=0.530). At the last follow-up, 29 patients in the FSIIN group were very satisfied with the operation, and 2 patients were satisfied with the operation, with a satisfaction rate of 100%. In PFNA group, 30 patients were very satisfied with the operation, 7 patients were satisfied with the operation, and the satisfaction rate was 100%. Conclusion:Compared with PFNA, micro-invasive and micro-stress shielding methodes of FSIIN in the fixation of anterograde intertrochanteric fractures is more minimally invasive, simple, time-saving, less bleeding, less risk, less pain, minimal stress shilding and enhanced recovery after surgery. The effect of treatment is similar in FSIIN and PFNA group.

ABSTRACT

Objective:To explore the efficacy of enhanced recovery after surgery (ERAS) in the perioperative treatment of elderly patients with intertrochanteric fracture in a primary hospital.Methods:Retrospectively analyzed were the data of 104 elderly patients with intertrochanteric femoral fracture who had been treated by fixation with proximal femoral nail antirotation (PFNA) at Joint & Trauma Surgery, Shangyu People's Hospital of Shaoxing from January 2017 to January 2019. According to whether the ERAS concept was applied perioperatively, the patients were divided into 2 groups. In the ERAS treatment group of 53 cases, there were 27 males and 26 females with an age of (72.7±1.5) years. By the AO classification, 27 cases were type 31-A1, 16 cases were type 31-A2, and 10 cases were type 31-A3. Internal diseases were complicated in 37 cases. The time from injury to operation was (65.8±3.9) h. In the conventional treatment group of 51 cases, there were 31 males and 20 females with an age of (72.6±1.5) years. By the AO classification, 21 cases were type 31-A1, 19 cases were type 31-A2, and 11 cases were type 31-A3. Internal diseases were complicated in 37 cases. The time from injury to operation was (111.5±5.9) h. The postoperative pain visual analogue scale (VAS), hospital stay, complications, Harris hip score at the last follow-up, and one-year mortality were compared between the 2 groups.Results:Except for the time from injury to operation, there was no significant difference in the other preoperative general data between the 2 groups, showing comparability ( P>0.05). All the 104 patients were followed up for 12 to 24 months (average, 14.8 months) after operation. The VAS pain score [(3.2±1.2) points], hospital stay [(6.6±2.2) d], complication rate [5.7% (3/53)], and hip Harris score at the last follow-up [(90.7±1.3) points] in the ERAS treatment group were significantly better than those in the conventional treatment group [(3.9±1.0) points, (12.7±1.8) d, 19.6% (10/51), and (86.5±3.8) points] ( P<0.05). There was no significant difference in the one-year mortality between the ERAS treatment group [18.9% (10/53)] and the conventional treatment group [27.5% (14/51)] ( P>0.05). No such complications were followed up as injury to nerve or blood vessel, wound infection, fracture nonunion or femoral head necrosis in this cohort. Conclusion:In the perioperative treatment of elderly patients with femoral intertrochanteric fracture in a primary hospital, compared with conventional treatment, application of ERAS concept can shorten the patients' hospital stay, reduce the incidence of postoperative complications, achieve rapid recovery, and improve the patients' satisfaction.

ABSTRACT

Objective:To analyze the risk factors for postoperative one-year mortality in elderly patients with femoral intertrochanteric fracture following multidisciplinary treatment (MDT) by intramedullary nailing.Methods:The clinical data were retrospectively analyzed of the 158 elderly patients with femoral intertrochanteric fracture who had undergone MDT by proximal femoral intramedullary nailing between January 2018 and August 2020 at Department of Orthopedics, Trauma Center, Zhongda Hospital Affiliated to Southeast University. There were 41 males and 117 females with an average age of 82.5 years (from 65 to 95 years). By the modified Evans classification, there were 15 cases of type Ⅰ, 16 cases of type Ⅱ, 35 cases of type Ⅲ, 81 cases of type Ⅳ, and 11 cases of type Ⅴ. The one-year mortality was documented in the patients after surgery. To screen for risk factors, univariate analysis was conducted of gender, age, body mass index (BMI), modified Evans classification of fractures, time from injury to operation, American Society of Anesthesiologists (ASA) classification, Charlson comorbidity index (CCI) and comorbidities, as well as preoperative hemoglobin (Hb), serum albumin (ALB) and total lymphocyte count (TLC). The factors with P<0.05 were included in the multivariate logistic regression model analysis to determine the risk factors. Results:A total of 13 patients died within one year after surgery, yielding a mortality of 8.2% (13/158). Univariate analysis showed significant differences in age, body mass index, modified Evans classification of fractures, CCI and Hb between the surviving and dead patients ( P<0.05). Multivariate logistic regression analysis showed that age >85 years ( OR=0.122, 95% CI: 0.018 to 0.834, P=0.032), BMI>23.9 kg/m 2 ( OR=0.083, 95% CI: 0.013 to 0.510, P=0.007), CCI≥3 points ( OR=0.051, 95% CI: 0.090 to 0.275, P=0.001) and preoperative Hb<90 g/L ( OR=4.733, 95% CI: 1.036 to 21.624, P=0.045) were the independent risk factors for postoperative one-year mortality in the elderly patients with intertrochanteric fracture following MDT by proximal femoral intramedullary nailing. Conclusions:After MDT by proximal femoral intramedullary nailing of femoral intertrochanteric fractures, the geriatric patients with an age >85 years, BMI>23.9 kg/m 2, CCI≥3 points and Hb<90 g/L are likely to die. Therefore, special care should be taken for them.

ABSTRACT

Objective:To compare the clinical efficacy between proximal femoral biomimetic intramedullary nail (PFBN) and traditional proximal femoral anti-rotation intramedullary nail (PFNA) in the treatment of senile osteoporotic intertrochanteric fractures.Methods:The data were retrospectively analyzed of the 92 elderly patients with osteoporotic intertrochanteric fracture who had been treated at Department of Orthopedics, People's Hospital of Xinjiang Uygur Autonomous Region from April to October in 2021. According to their internal fixation methods, the patients were divided into 2 groups.In the PFBN group of 46 patients, there were 22 males and 24 females, with an age of (75.7±5.2) years and time from injury to operation of (3.1±0.4) d; in the PFNA group of 46 patients, there were 20 males and 26 females, with an age of (75.3±4.2) years and time from injury to operation of (3.3±0.5) d. Recorded were the operation time, intraoperative blood loss, hospital stay, fracture reduction quality, postoperative weight bearing time, hip function and complications at the last follow-up.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The operation time in the PFBN group was (47.3±11.4) min, significantly longer than that in the PFNA group [(39.2±15.3) min] ( P<0.05); the postoperative weight-bearing time in the former was (7.9±2.7) d, significantly shorter than that in the PFNA group [(21.2±5.7) d] ( P<0.05). There were no significant differences between the 2 groups in the intraoperative blood loss [(130.6±21.3) mL versus (123.5±17.8) mL], hospital stay [(4.2±1.6) d versus (4.6±2.1) d], the excellent and good rate of Francisco score [89.1% (41/46) versus 87.0% (40/46)], fracture healing time [(12.3±0.5) weeks versus (12.6±0.7) weeks], or the excellent and good rate of Harris hip score at the last follow-up [89.1% (41/46) versus 87.0% (40/46)] (all P>0.05). Conclusion:Both PFBN and PFNA can achieve satisfactory clinical results in the treatment of osteoporotic intertrochanteric fractures in the elderly patients, but PFBN may provide more reliable early stability and reduce patient bedtime than PFNA.

ABSTRACT

Objective:To investigate the analgesic effect of ultrasound-guided pericapsular nerve group (PENG) block combined with laryngeal mask general anesthesia and internal fixation of proximal femoral nail antirotation (PFNA) under ERAS concept in elderly patients.Methods:A total of 50 elderly patients with femoral trochanteric fractures treated with PFNA internal fixation who were admitted to Changsha Central Hospital from January 2021 to March 2022 were selected and according to the random number table method, they were divided into groups P and F, with 26 cases in group P (ultrasound-guided PENG block combined with laryngeal mask general anesthesia group) and 24 cases in group F [ultrasound-guided fascia iliaca compartment block (FICB)] combined with laryngeal mask general anesthesia group]. The bispectral index (BIS) of the two groups of patients was maintained within the range of 40-60, and the dosage of cyclopofol and remifentanil was adjusted according to the BIS and hemodynamic changes. Postoperative oxycodone was used for patient controlled intravenous analgesia (PCIA). When the Visual Analogue Scale (VAS) score ≥4, 1 mg intravenous oxycodone was administered as rescue analgesia. The VAS score was observed and recorded before nerve block (T 0), 10 minutes after nerve block (T 1), 20 minutes after nerve block (T 2), when the patients were placed in body position after bed (T 3), after laryngeal mask removal (T 4), 12 h after operation (T 5), 24 h after operation (T 6) and 48 h after operation (T 7). The mean arterial pressure (MAP), heart rate (HR) and blood oxygen saturation (SpO 2) at each time point from T 0 to T 4 were observed and recorded; the intraoperative dose of remifentanil, the rescue dose of oxycodone at postoperative T 6 and T 7, Lovett muscle strength score, anesthesia operation time, anesthesia recovery time and postoperative anesthesia-related complications were recorded. Results:There was no significant difference between the two groups in VAS scores at T 0, T 4, T 5 and T 6, MAP, HR and SpO 2 at T 0, T 1, T 2 and T 4, the dosage of remifentanil during operation, the remedial dosage of oxycodone at T 6 after operation, anesthesia operation time and anesthesia recovery time (all P>0.05). Compared with group F, the VAS scores of group P at T 1, T 2, T 3 and T 7 were lower than those of group F (all P<0.05); At T 3, there was no significant difference in SpO 2 between the two groups ( P>0.05), but the MAP and HR in group P was lower than that in group F (all P<0.05); The remedial dose of oxycodone at T 7 in group P was lower than that in group F ( P<0.05), and the analgesic effect was longer; Lovett muscle strength score at T 6 and T 7 in group P was better than that in group F (all P<0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). Conclusions:Compared with FICB, ultrasound-guided PENG block used in PFNA internal fixation in elderly patients has faster effect, lower dosage of opioid analgesics, longer duration of analgesia, and less impact on postoperative lower limb muscle strength.

ABSTRACT

Objective:To investigate the efficacy of internal fixation with common intramedullary nail versus bone cement reinforced antirotation intramedullary nail in the treatment of femoral intertrochanteric fracture. Methods:A total of 106 patients with femoral trochanteric fractures who were surgically treated in Weihaiwei People's Hospital from January 2018 to January 2019 were selected and divided into a control group and an observation group with 53 patients in each group. The control group received internal fixation with common intramedullary nails. The observation group was fixed with bone cement reinforced anti-rotation intramedullary nails. The therapeutic effects were compared between the two groups.Results:There were no significant differences in the amount of blood loss, postoperative Visual Analogue Scale score, amount of fluid drainage, postoperative time to get out of bed, and postoperative hospital stay between the two groups ( t = 1.33, 0.19, 0.34, 0.58, 0.37, all P > 0.05). Operative time in the observation group was significantly longer than that in the control group [(80.21 ± 6.52) minutes vs. (75.92 ± 8.15) minutes, t = 2.99, P < 0.05]. Time to fracture healing in the observation group was significantly shorter than that in the control group [(9.25 ± 1.12) weeks vs. (10.05 ± 1.31) weeks, t = 3.37, P < 0.05]. The incidence of complications in the observation group was significantly lower than that in the control group [3.77% (2/53) vs. 16.98% (9/53), χ2 = 4.97, P = 0.025]. At 6 and 12 months after surgery, Harris hip scores in the observation group were (82.84 ± 6.58) points and (85.55 ± 7.91) points, respectively, which were significantly higher than (78.35 ± 7.54) points and (79.92 ± 9.94) points in the control group ( t = 3.26, 3.22, both P < 0.05). Conclusion:Internal fixation with bone cement-reinforced anti-rotation intramedullary nails for treatment of femoral trochanteric fractures can shorten the time to fracture healing, reduce complications, and improve hip joint function.

ABSTRACT

OBJECTIVE@#To explore the effect of intermittent pneumatic compression(IPC) combined with 3M thermometer on the prevention of deep venous thrombosis(DVT) in patients with femoral intertrochanteric fracture.@*METHODS@#From March 2016 to August 2019, 127 patients with femoral intertrochanteric fractures who underwent proximal femoral nail antirotation(PFNA) were retrospectively analyzed. They were divided into two groups according to different methods of thrombus prevention and treatment. Among them, 63 patients in group A did not use IPC and 3M thermometer;64 cases in group B were treated with IPC combined with 3M thermometer. Color Doppler ultrasound was used to dynamically monitor the DVT and changes of lower limbs during perioperative period. The venous thrombosis of lower limbs was monitored at 0, 24, 72 h and > 72 h after operation(recheck every 3 days until discharge).@*RESULTS@#Occurrence of DVT of lower limbs after PFNA operation in two groups:there were 5 cases (7.8%) in group B and 20 cases (31.7%) in group A, there was significant difference between two groups (P=0.001). There was no significant difference in lower limb DVT between two groups at 0, 72 and > 72 h after operation(P>0.05), but the formation rate of group A was significantly higher than that of group B at 24 h after operation (P=0.049). There was no significant difference in DVT formation between group A and group B(P>0.05). However, the formation of DVT in group A was significantly higher than that in group B(P=0.012).@*CONCLUSION@#Intraoperative IPC combined with 3M thermostat can effectively prevent DVT of lower limbs in patients undergoing PFNA surgery.
