ObjectiveTo compare the effectiveness of long and short proximal femoral nail anti-rotation (PFNA) in the treatment of type A2.3 intertrochanteric fracture of femur (IFF). Methods The clinical data of 54 patients with type A2.3 IFF admitted between January 2020 and December 2022 were retrospectively analyzed. According to the length of PFNA nail used in the operation, they were divided into long nail group (PFNA nail length>240 mm, 24 cases) and short nail group (PFNA nail length≤240 mm, 30 cases). There was no significant difference in baseline data such as gender, age, fracture side, body mass index, and time from fracture to operation between the two groups (P>0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, intraoperative reduction quality score, fracture healing, and complications of the two groups were recorded and compared. Harris score was used to evaluate the hip function of patients at 1 year after operation. According to the relationship between the fracture line of type A2.3 IFF and the lesser trochanter, the two groups of patients were divided into type Ⅰ(the fracture line extends to the level of the lesser trochanter), type Ⅱ(the fracture line extends to less than 2 cm below the lesser trochanter), and type Ⅲ (the fracture line extends to more than 2 cm below the lesser trochanter), and the postoperative stability and internal fixator loosening of each subtype were evaluated. Results The operation time, intraoperative blood loss, and intraoperative fluoroscopy frequency in short nail group were significantly less than those in long nail group (P<0.05). There was no significant difference in the intraoperative reduction quality score between the two groups (P>0.05). Patients in both groups were followed up 12-18 months, with an average of 13.5 months. The postoperative stability score of short nail group was significantly lower than that of long nail group (P<0.05). The Harris score in the long nail group was significantly higher than that in the short nail group at 1 year after operation (P<0.05), but there was no significant difference in Harris score grading between the two groups (P>0.05). Complications occurred in 3 cases of the long nail group (including 1 case of coxa varus caused by external nail entry point and 2 cases of loose internal fixator), and 7 cases of the short nail group (including 1 case of coxa varus caused by external nail entry point and 6 cases of loose internal fixator). Neither group had any anterior femoral arch damage, there was no significant difference in the incidence of complications between the two groups (P>0.05). The number of type Ⅲ patients was relatively small and not included in the statistics; there was no significant difference in the postoperative stability score and the incidence of internal fixator loosening between the long and short nail groups in type Ⅰ patients (P>0.05). In type Ⅱ patients, the postoperative stability score and the incidence of internal fixation loosening in the long nail group were significantly better than those in the short nail group (P<0.05).Conclusion Long PFNA fixation for type A2.3 IFF has longer operation time and more intraoperative blood loss, but the overall stability of fracture is better after operation. For type A2.3 IFF with fracture line extending to less than 2 cm below the lesser trochanter, long PFNA is used for fixation, although the surgical trauma is large, but the postoperative stability is better than that of short PFNA; for type A2.3 IFF with fracture line extending to the lesser trochanter, there is no significant difference in postoperative stability between long and short PFNAs.
ObjectiveTo explore the effectiveness of proximal femoral nail antirotation (PFNA) assisted by mesh locator in treatment of intertrochanteric fracture in the elderly.MethodsNinety-four elderly patients with intertrochanteric fractures admitted between August 2014 and July 2017 were selected as the study subjects. They were randomly divided into trial group (48 cases) and control group (46 cases). In trial group, PFNA was implanted assisted by mesh locator after closed reduction; while in control group, PFNA was implanted by conventional method. There was no significant difference between the two groups in terms of gender, age, cause of injury, time from injury to admission, fracture side and classification, and medical complications (P>0.05). The operation time, intraoperative blood loss, fluoroscopy times, hospital stay, incision length, and complications were recorded. Visual analogue scale (VAS) was used to evaluate the degree of pain at 3 days after operation, and Harris score was used to evaluate hip function before operation and at 3, 6, and 9 months after operation.ResultsCompared with control group, the operation time and incision length of trial group shortened, the blood loss and fluoroscopy times reduced, the pain after operation alleviated obviously; the differences between the two groups were significant (P<0.05). There was no significant difference in hospital stay between the two groups (P>0.05). The patients in both groups were followed up 9-12 months, with an average of 10.6 months. X-ray films showed that the fractures healed in both groups, and the healing time in control group was (11.2±3.2) weeks, while that in trial group was (11.6±2.9) weeks, showing no significant difference between the two groups (t=1.262, P=0.120). There was no significant difference in Harris score between the two groups before operation and at 3, 6, and 9 months after operation (P>0.05). There was 1 case of incision infection, 2 cases of coxa vara, and 1 case of pressure ulcer in trial group, and the incidence of complications was 8.3%. There was 1 case of coxa vara, 2 cases of pressure ulcer, and 1 case of internal fixation loss in control group, and the incidence of complications was 8.7%. There was no significant difference in the incidence of complications between the two groups (χ2=0.783, P=0.112).ConclusionIt is feasible to implant PFNA assisted by mesh locator in treatment of intertrochanteric fracture in the elderly. Compared with the traditional operation, it can shorten the operation time, shorten the incision, and relieve the pain after operation.
ObjectiveTo investigate the effect of the screw blade position on the effectiveness of proximal femoral nail anti-rotation (PFNA) internal fixation for unstable intertrochanteric fractures in the elderly.MethodsA clinical data of 131 elderly patients with unstable intertrochanteric fractures who were treated with PFNA internal fixation between January 2010 and January 2017 was retrospectively analyzed. According to the anteroposterior X-ray films, the screw blades were placed in the middle of the femoral neck in 72 patients (group A) and at one-third of the femoral neck in 59 patients (group B). There was no significant difference between the two groups (P>0.05) in the gender, age, bone density, classification of fractures, other medical diseases, and the time between injury and operation. Multiple treatment indexes were analyzed, including complications, hip Harris score, the healing status of fracture, tip-apex distance (TAD), and the height of the tail nail.ResultsAll patients were followed up 11-14 months, with an average of 12.1 months. All incisions healed by first intention with no complications. All fractures healed and no significant difference in bone healing time between the two groups (Z=−0.190, P=0.849). At 6 months after operation, TAD was (2.23±0.07) cm in group A and (2.85±0.12) cm in group B, showing significant difference (t=−47.643, P=0.000); and the height of the tail nail was (1.72±0.14) cm in group A and (0.53±0.26) cm in group B, showing significant difference (t=31.031, P=0.000). According to the Harris score, the hip functions were rated as excellent in 48 cases, good in 15 cases, and poor in 9 cases in group A, while as excellent in 38 cases, good in 16 cases, and poor in 5 cases in group B, with no significant difference between the two groups (Z=−0.075, P=0.941).ConclusionFor the unstable intertrochanteric fracture in the elderly, the PFNA internal fixation with appropriated TAD and the screw blades placed in the middle or at one-third of the femoral neck can obtain good effectiveness.
ObjectiveTo investigate the effectiveness of proximal femoral nail anti-rotation (PFNA) and cerclage fixation for complicated femoral subtrochanteric fractures.MethodsA clinical data of 74 patients with complicated femoral subtrochanteric fractures, who were admitted between March 2016 and March 2019 and met the criteria, was retrospectively analyzed. Among them, 39 patients were treated with limited open reduction and PFNA combined with cerclage fixation (observation group) and 35 patients were treated with closed reduction and PFNA fixation (control group). There was no significant difference in gender, age, cause of injury, side and type of fracture, and the time from injury to operation (P>0.05). The ratio of postoperative hemoglobin (1, 3, and 5 days) to the preoperative hemoglobin, the operation time, the first weight-bearing time after operation, and the hospital stay were recorded. X-ray films were taken to observe fracture healing in the two groups and bone resorption around the cerclage in the observation group, and the fracture healing time was recorded. Hip function was evaluated by Harris scoring. ResultsThe operation time of the observation group was significantly longer than that of the control group (P<0.05), but the first weight-bearing time and hospital stay were significantly shorter (P<0.05). All patients were followed up 12 months. There was no significant difference in the ratios of post- to pre-operative hemoglobin (1, 3, and 5 days) between the two groups (P>0.05). X-ray film reexamination showed that the fractures of the two groups healed smoothly, and the fracture healing time of the observation group was significantly shorter than that of the control group (t=−12.989, P=0.000). No bone resorption around the cerclage occurred in the observation group. The Harris scores of the observation group were better than those of the control group at 7 days and 1, 2, and 3 months after operation (P<0.05), and there was no significant difference between the two groups at 6 months after operation (t=1.329, P=0.180).ConclusionCompared with PFNA fixation, PFNA combined with cerclage fixation for the complicated femoral subtrochanteric fractures has a shorter operation time, and can obtain immediate stability after fixation, which can meet the needs of patients for early functional exercise.
Objective To evaluate effectiveness of proximal femur bionic nail (PFBN) in treatment of intertrochanteric fractures in the elderly compared to the proximal femoral nail antirotation (PFNA). Methods A retrospective analysis was made on 48 geriatric patients with intertrochanteric fractures, who met the selection criteria and were admitted between January 2020 and December 2022. Among them, 24 cases were treated with PFBN fixation after fracture reduction (PFBN group), and 24 cases were treated with PFNA fixation (PFNA group). There was no significant difference in baseline data such as age, gender, cause of injury, side and type of fracture, time from injury to operation, and preoperative mobility score, American Society of Anesthesiologists (ASA) score, Alzheimer’s disease degree scoring, self-care ability score, osteoporosis degree (T value), and combined medical diseases between the two groups (P>0.05). The operation time, intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, occurrence of complications, weight-bearing time after operation, and postoperative visual analogue scale (VAS) score, walking ability score, mobility score, self-care ability score were recorded and compared between the two groups. And the radiographic assessment of fracture reduction quality and postoperative stability, and fracture healing time were recorded. ResultsThe operations in both groups were successfully completed. All patients were followed up 6-15 months with an average time of 9.8 months in PFBN group and 9.6 months in PFNA group. The operation time was significantly longer in PFBN group than in PFNA group (P<0.05), but there was no significant difference in intraoperative blood loss, number of blood transfusions, transfusion volume, length of hospital stay, change in activity ability score, and change in self-care ability score between the two groups (P>0.05). The weight-bearing time after operation was significantly shorter in PFBN group than in PFNA group (P<0.05), and the postoperative VAS score and walking ability score were significantly better in PFBN group than in PFNA group (P<0.05). Radiographic assessment showed no significant difference in fracture reduction scores and postoperative stability scores between the two groups (P>0.05). All fractures healed and there was no significant difference in fracture healing time between the two groups (P>0.05). The incidence of complications was significantly lower in PFBN group (16.7%, 4/24) than in PFNA group (45.8%, 11/24) (P<0.05). ConclusionCompared with PFNA, PFBN in the treatment of elderly intertrochanteric fractures can effectively relieve postoperative pain, shorten bed time, reduce the risk of complications, and facilitate the recovery of patients’ hip joint function and walking ability.
Objective To summarize the short-term effectiveness of the surgical treatment for grade III pronation-external rotation ankle fractures. Methods Between October 2011 and May 2015, 36 patients with pronation-external rotation ankle fractures (grade III) were treated with internal fixation and repair of the anterior lower tibiofibular ligament, including 21 males and 15 females with an average age of 45.2 years (range, 21-72 years). Injury was caused by sprain in 19 cases, by traffic accident in 6 cases, and by falling from height in 11 cases. All patients had closed fractures, with no blood vessel and nerve injury. The locations were the left ankle in 13 cases and the right ankle in 23 cases. The time from injury to operation was 3 to 10 days (mean, 6.5 days). At last follow-up, ankle function was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) ankle-foot score, and the improvement of pain was evaluated by visual analogue scale (VAS). Results Primary healing of incision was obtained in all patients, no incision infection and skin necrosis occurred. Twenty-eight patients were followed up 12-36 months (mean, 17.5 months). X-ray films showed bone union was achieved within 2.6-5 months (mean, 3.2 months). No fracture of internal fixation and disruption of tibiofibular diastasis occurred. At last follow-up, according to AOFAS score for ankle function evaluation, the pain score was 36.3±2.9, the function score was 44.3±3.2, the ligament condition score was 9.2±0.5, and the total score was 89.8±6.6; the results were excellent in 11 cases, good in 15 cases, and fair in 2 cases. VAS score was 1.6±0.5. The range of motion of the ankle was (13±5)° in dorsiflexion and (38±9)° in planteroflexion. Conclusion Repair of anterior tibial ligament is an effective method to treat tibiofibular diastasis injury in the surgical treatment of grade III pronation-external rotation ankle fractures, with convenient operation, and satisfactory short-term effectiveness.
Objective To explore the effectiveness of additional anti-rotation steel plate assisted intramedullary nail technology in treatment of aseptic femoral non-union patients. Methods A retrospective analysis was conducted on 21 patients with aseptic femoral non-union who admitted between September 2020 and October 2024 and treated with additional anti-rotation steel plate assisted intramedullary nail technology. There were 17 males and 4 females, aged 25-67 years (mean, 44 years). There were 19 cases of femoral anterograde intramedullary nail fixation, 1 case of femoral retrograde intramedullary nail fixation, and 1 case of steel plate fixation with fatigue fracture. There were 9 cases of hypertrophic non-union and 12 cases of atrophic non-union. All patients had varying degrees of fracture end atrophy/sclerosis. Among them, 20 patients who were fixed with intramedullary nails underwent removal of soft tissue and hardened bone at the fracture end, and cortical treatment resulted in the appearance of “chili sign” at the fracture end. Iliac bone grafting and anti-rotation steel plate fixation were performed. One patient with steel plate fixation was removed the steel palte and fixed with a retrograde intramedullary nail, while the hardened bone at the fracture end was removed, iliac bone grafting and anti-rotation steel plate fixation were performed. Postoperative follow-up observation included the incision healing, maximum knee flexion range of motion, bone healing, length of lower limbs, and subjective satisfaction. The lower extremity functional scale (LEFS) score was used to evaluate the lower limb function. Results All incisions healed by first intention. All patients were followed up 7-26 months (mean, 15.5 months). At last follow-up, the femoral fracture healed with the obvious callus formation at the fracture end; the maximum knee flexion range of motion was 95°-127° (mean, 112.67°). The LEFS score increased from 29.9±6.7 before operation to 75.9±3.0 at last follow-up, and the difference was significant (t=−29.622, P<0.001). Except for 1 patient who underwent intramedullary nail dynamic treatment before operation and had a lower limb shortening of about 0.9 cm, the other patients had bilateral lower limbs of equal length. All patients had no postoperative infections, mal-union of fractures, deep vein thrombosis, joint stiffness, or other complications. Conclusion The use of additional anti-rotation steel plate assisted intramedullary nail technology in the treatment of aseptic femoral non-union not only overcomes the drawbacks of insufficient stability at the fracture end of intramedullary nails, but also overcomes the shortcomings of biased fixation with steel plates. It has the advantages of minimal trauma, effective maintenance of fracture stability, and ideal postoperative functional recovery, making it an effective treatment for aseptic femoral non-union.
ObjectiveTo explore the difference of the proximal femoral shortening (PFS) between the third generation of Gamma nail (TGN) and the proximal femoral nail anti-rotation (PFNA) in treating intertrochanteric fracture of femur.MethodsThe clinical data of 158 patients with intertrochanteric fracture of femur who were treated with TGN internal fixation or PFNA internal fixation between January 2014 and December 2015 were retrospectively analysed. The patients were divided into TGN group (69 cases) and PFNA group (89 cases) according to surgical operation. There was no significant difference in gender, age, bone mineral density, causes of injury, AO/Association for the Study of Internal Fixation (AO/ASIF) classification, accompanied disease, and the time from injury to operation between 2 groups (P>0.05). The result of fracture reduction was divided into 3 types: positive medial cortex support, neutral position cortex support, and negative medial cortex support according to the method of Changet al. At 18 months postoperatively, bilateral hip anteroposterior X-ray films were taken to measure horizontal PFS values (marked as X), vertical PFS values (marked as Y), and calculate the total PFS values (marked as Z). The PFS values were divided into 4 grades according to the criteria (≤1.0 mm, 1.0-4.9 mm, 5.0-9.9 mm, and ≥10.0 mm), and the constituent ratio was calculated and compared between 2 groups. The X, Y, and Z values and the collodiaphyseal angles of 2 groups at 18 months postoperatively were compared. The X, Y, and Z values of 2 groups of patients with failed fixation and normal healing within 18 months after operation were recorded and compared. The X, Y, and Z values of 2 groups of the patients with different cortex support types were also compared.ResultsThere were 34 cases of positive medial cortex support, 30 cases of neutral position cortex support, and 5 cases of negative medial cortex support in TGN group, and there were 45, 33, and 11 cases in PFNA group respectively, showing no significant difference between 2 groups (Z=–1.06, P=0.29). All patients were followed up 18 months after operation. At 18 months after operation, the constituent ratios of PFS values (X, Y, Z) had significant differences between 2 groups (P<0.05). The patients of shortening of 1.0-4.9 mm and 5.0-9.9 mm were obviously more in TGN group than in PFNA group; the patients of shortening of ≥10.0 mm were obviously more in PFNA group than in TGN group. There were significant differences in X, Y, and Z values between 2 groups (P<0.05), but no significant difference of the collodiaphysial angle was found between 2 groups (t=0.47, P=0.64). Six cases of internal fixation failed in TGN group and PFNA group respectively within 3 months after operation, and there was no significant difference of X, Y, and Z values between failed fixation and normal healing patients within 2 groups (P>0.05). When the reposition effect was the positive medial cortex support, the X, Y, and Z values were significantly lower in TGN group than in PFNA group (P<0.05); but no significant difference was found between 2 groups when the reposition effect was the neutral position cortex support or negative medial cortex support (P>0.05). At 18 months after operation, the X, Y, and Z values of the negative medial cortex support patients were significantly higher than those of the positive medial cortex support or the neutral position cortex support patients within 2 groups (P<0.05).ConclusionPFS is a common complication of the intertrochanteric fracture of the femur after internal fixation. During operation, the selection of internal fixation should be based on the results of intraoperative reduction. TGN should be applied to reduce PFS if positive medial cortex support happened.
ObjectiveTo evaluate the biomechanical characteristics and effectiveness of repairing anteroinferior tibiofibular ligament and fixing the posterior malleolar fracture in reconstructing syndesmotic stability after ankle fracture of pronation-external rotation type (PER) stage IV. MethodsTwenty-four normal lower extremity cadaver specimens were collected and made into intact ankle specimens. A MTS Bionix 858 test system was used to measure the maximum rotation of the foot under a static axial load of 150 N, internal rotation torque to the tibia at a rate of 1°/second and 4 N·m torque. Then a fracture of PER stage IV model was established in each specimen. Internal fixation of lower tibiofibular ligament union was performed by screws in group A, fixation of posterior malleolar fractures in group B, fixing posterior malleolar fracture combined with repairing anteroinferior tibiofibular ligament in group C (8 specimens each group). Then the maximum rotation of the foot was measured under the same condition, and the syndesmotic stability was calculated. Between July 2009 and September 2012, 32 patients with ankle fracture of PER stage IV were treated. There were 19 males and 13 females with an average age of 35 years (range, 20-63 years). The locations were the left ankle in 14 cases and the right ankle in 18 cases. The time from injury to admission was 3.5 hours on average (range, 1-72 hours). Open reduction and plate compression internal fixation were performed in fibula, and medial malleolus was fixed by conpression screws, then anteroinferior tibiofibular ligament was mended and posterior malleolar fracture was fixed by screws. ResultsThe preservation rates of syndesmotic stability after repair were 46.2%±12.3%, 62.6%±10.7%,and 66.5%±12.6% in groups A, B,and C, respectively; groups B and C were significantly superior to group A (P<0.05),but no significant difference was found between groups B and C (P>0.05). All patients achieved wound healing by first intention, and were followed up 12-24 months (mean,15 months). All fractures healed,with an average healing time of 11.2 weeks (range, 10-14 weeks) on the X-ray films. No seperation of inferior tibiofibular syndesmosis was observed during the follow-up period. American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score was 88.4 on average (range, 61-98) at last follow-up; the results were excellent in 13 cases,good in 15 cases, and fair in 4 cases, with an excellent and good rate of 87.5%. ConclusionIn patients with ankle fracture of PER stage IV, a combination of fixing the posterior malleolar fracture and repairing anteroinferior tibiofibular ligament can reconstruct syndesmotic stability effectively.
Objective To investigate the clinical features, diagnosis, and surgical methods of left-sided appendicitis (LSA). Methods We retrieved LSA-related literatures through Pubmed, Google Scholar English databases, Wanfang, CNKI, VIP, and SinoMed databases (published from January 1981 to June 2017), as well as 2 cases of LSA who treated in Beibei Traditional Chinese Medical Hospital, to analyze the clinical characteristics of LSA and its diagnosis and treatment methods. Results There were 92 articles in a total of 212 LSA patients were retrieved, and 2 cases treated in Beibei Traditional Chinese Medical Hospital, a total of 214 LSA patients were included in the analysis. Pain fixed position of LSA: 139 cases (65.0%) located in left-lower quadrant, 30 cases (14.0%) located in right-lower quadrant, 8 cases (3.7%) located in peri-umbilical, 15 cases (7.0%) located in mid-lower abdomen, 15 cases (7.0%) located in left-upper quadrant, 3 cases (1.4%) located in right-upper abdomen, 2 cases (0.9%) located in mid-upper abdomen, 2 cases (0.9%) located in pelvic cavity, respectively. LSA had occurred in association with several types of abnormal anomalies: 131 cases (61.2%) suffered from situs inversus totalis (SIT), 53 cases (24.8%) suffered from midgut malrotation (MM), 21 cases (9.8%) suffered from cecal malrotation, 4 cases (1.9%) suffered from long appendix, 2 cases (0.9%) suffered from free ascending colon, and 3 cases (1.4%) were unclear. The diagnosis of 114 LSA cases (53.3%) before operation was correct, in which the correct diagnosis rates of SIT-LSA and MM-LSA were 74.8% (98/131) and 22.6% (12/53), respectively. Three patients (1.4%) underwent conservative treatment, and 211 patients (98.6%) underwent surgical treatment, including 25 cases (11.7%) of laparoscopic surgery, 145 cases (67.8%) of open abdominal surgery, and unknown of 41 cases (19.1%). Laparotomy incision: abdominal incision in 74 cases (51.0%), ventral midline incision in 16 cases (11.0%), the left side of the anti McBurney incision in 43 cases (29.7%), right McBurney incision in 12 cases (8.3%). Conclusions LSA mainly occurs in association with 2 types of congenital anomalies: SIT and MM. There is some difficult to make diagnosis for abnormal anatomy and inaccurate pain location of LSA, so it is easy to cause the delay in diagnosis or misdiagnosis. For LSA, the choices of laparoscopy or laparotomy operation methods are applicable.
