OBJECTIVE: To investigate the short-to-medium-term clinical efficacy of total hip arthroplasty(THA) with Pinnacle ES constrained liner in the treatment of femoral neck fractures(FNF) associated with lower limb neuromuscular disorders. METHODS: A retrospective analysis was conducted on 16 patients who underwent primary THA using Pinnacle ES constrained liner for FNF with lower limb neuromuscular disorders and had complete follow-up data, treated between January 2020 and January 2023. There were 7 males and 9 females, with a mean age of (68.42±3.58) years old ranging from 61 to 75 years old. Among them, 10 cases had left-sided fractures and 6 had right-sided fractures;based on the Garden classification, 11 cases were type Ⅲ and 5 cases were type Ⅳ. The affected limbs were complicated with sequelae of poliomyelitis (2 cases), Parkinson's disease (2 cases), and sequelae of cerebral infarction (12 cases). All operations were performed via a posterolateral approach. Prosthesis position was evaluated using imaging data. Hip function was assessed by the Harris hip score(HHS) and Merle D'Aubigne hip score. During the follow-up period, the occurrence of complications such as prosthetic dislocation, loosening, and infection was recorded. RESULTS: One patient died of advanced tumor 2 years after surgery, and the remaining 15 patients were followed up for 24 to 64 months with a mean of (34.8±5.5) months. The operation time ranged from 50 to 90 minutes with a mean of (75.56±8.15) minutes, and the blood loss ranged from 150 to 200 ml with a mean of (170.32±12.56) ml. All patients achieved primary wound healing after surgery. Intraoperatively, femoral calcar splitting occurred in 2 cases, which were treated with titanium cable binding;no neurovascular injuries were observed in any case. The mean HHS increased from (18.95±2.25) preoperatively to (88.02±2.42) at the last follow-up, and the mean Merle D'Aubigne Score increased from (3.05±0.06) preoperatively to (16.65±0.93) at the last follow-up. Postoperative follow-up X-rays showed good prosthetic position, and no complications such as dislocation, prosthetic loosening, periprosthetic fracture, or deep infection occurred during the follow-up period. CONCLUSION Total hip arthroplasty with Pinnacle ES constrained liner is effective in the treatment of femoral neck fractures associated with lower limb neuromuscular disorders. It can significantly improve hip function, reduce the postoperative prosthetic dislocation rate, provide good initial stability, and achieve satisfactory short-to-medium-term clinical efficacy.

PURPOSE: Over 30,000 hip hemiarthroplasties for neck of femur fractures are performed annually in the United Kingdom (UK). The national recommendation is via the lateral approach, to reduce the risk of dislocation, with the potential expense of reduced function and mobility post-operatively. Muscle-sparing approaches, such as SPAIRE (sparing piriformis and internus repairing externus), have been invented to address the issue of dislocation. METHODS: We performed a retrospective data collection at a single center with a high annual volume of hip hemiarthroplasties over 12 months. All patients who had hip hemiarthroplasty as their primary treatment were included. Patients who passed away and were non-ambulant before their surgery were excluded from the study. Our primary outcome was the dislocation rate and secondary outcomes were the time to mobilization after surgery and the duration of surgery. Statistical analysis was performed using XLSTAT software. RESULTS: We identified 194 cases, and these were divided into 3 groups based on the surgical approach: SPAIRE (n = 43), lateral (n = 97), and posterior (n = 54). Groups had similar demographics and a minimum 3-month follow-up after surgery. There were no dislocations in the SPAIRE group, whereas the dislocation rate for the other 2 groups was 2.5% in the lateral and 9.1% in the posterior groups at 6 months post-surgery. There was an earlier return to mobility in the SPAIRE (1.4 day) compared to the 2 other groups ( 2 days and 2.6 days). Average surgical times were very similar among all 3 groups (74 min vs. 79 min vs. 71 min). CONCLUSION The SPAIRE approach seems to be safe and provides a low risk of dislocation and good post-operative function for patients undergoing hip hemiarthroplasties.

PURPOSE: Femur fractures are among the most common fractures treated surgically, representing a significant challenge for the orthopedic surgeon. Peri-implant femoral fractures (PIFFs) represent a rare complication of the surgical treatment. It is necessary to pay attention during osteosynthesis, evaluating not only the fracture site but the entire femoral skeletal structure, the characteristics of the fracture, the health comorbidities, and the risk of malunion and pseudarthrosis. There are few studies on the incidence, treatment, and outcomes of PIFFs near osteosynthesis. This study aimed to investigate PIFF after osteosynthesis of femoral fractures and evaluate the mortality after surgery and the morbidity associated with these types of fractures. METHODS: A retrospective cohort study was carried out at the IRCCS Galeazzi Orthopedic Institute, Milan, Italy, between January, 2017 and December, 2022. Inclusion criteria were the presence of a femur fracture around an intramedullary nail to treat a previous fracture, follow-up ≥ 12 months, and patients aged ≥ 65 years. Exclusion criterion was intraoperative periprosthetic fractures. The data were expressed as frequency and percentage. Continuous variables were expressed as mean ± standard deviation or median and range. RESULTS: Overall, 25 patients were enrolled (88.0% female) and the mean age was 84.5 years (range of 70 - 92 years). There were 20 patients having type B PIFF and 5 having type C. In 22 patients, multiple comorbidities were found with an average Charlson comorbidity score of 5.5 and the mean time to peri-implant fracture was 38 months. After surgery, 1 patient (4.0%) presented renal failure, 1 (4.0%) needed removal surgery for their loosening, and 2 (8.0%) presented surgical site infection. Nine patients (36.0%) died within 1 year with a mortality rate of 20.0% at 30 days, 8.0% at 3 months, and 8.0% at 12 months. CONCLUSIONS PIFFs in elderly patients are associated with high short-term mortality and morbidity, so careful planning for primary fracture surgery and patient awareness to ensure prolonged compliance and a healthy lifestyle are essential for prevention.

OBJECTIVE: To investigate the incidence of perioperative deep venous thrombosis (DVT) of lower extremities and its risk factors in elderly patients with femoral neck fracture. METHODS: The clinical data of 4 109 elderly patients with femoral neck fracture admitted between August 2012 and November 2020 and met the selection criteria were retrospectively analyzed. Among them, there were 1 137 males and 2 972 females; their ages ranged from 65 to 101 years, with an average of 77.0 years. The time from fracture to admission ranged from 1 to 360 hours, with an average of 35.2 hours. There were 1 858 cases of hemiarthroplasty, 1 617 cases of total hip arthroplasty, and 634 cases of internal fixation surgery. The preoperative age-adjusted Charlson comorbidity index (aCCI) was 4 (3, 5). Perioperative DVT occurred in 857 cases (20.9%). Univariate analysis was performed on age, gender, body mass index, fracture side, time from fracture to admission, operation type, anesthesia type, blood transfusion, blood pressure after admission, and preoperative aCCI in patients with and without perioperative DVT, and logistic regression analysis was used to screen the risk factors of perioperative DVT in elderly patients with femoral neck fracture. RESULTS: Univariate analysis showed that there were significant differences in age, gender, time from fracture to admission, operation type, and preoperative aCCI between the two groups ( P<0.05). Further logistic regression analysis showed that age>75 years, female patients, time from fracture to admission>24 hours, and preoperative aCCI>5 were risk factors for perioperative DVT ( P<0.05). CONCLUSION Elderly patients with femoral neck fracture have a higher incidence of perioperative DVT. The advanced aged and female patients, patients with longer fracture time and more comorbidities need to pay special attention to the prevention of perioperative DVT to minimize the occurrence of DVT during femoral neck fractures.

There are still many unresolved problems in the treatment and prognosis of nondisplaced femoral neck fractures, such as nonunion and avascular necrosis of the caput femoris .In order to reduce the risk of various complications after non-displaced femoral neck fractures, the caput femoris posterior tilt of femoral neck fractures and its impact on prognosis have attracted more and more attention. A large number of scholars' studies have found that when the posterior tilt exceeds 20°, the risk of internal fixation failure increases significantly. Based on this concept, we can choose to use primary artificial joint replacement instead of three-screw internal fixation according to the different posterior tilt angles of patients to reduce the incidence of postoperative complications. At the same time, our analysis found that comminution of the posterior segment of the femoral neck would lead to an increase in the posterior inclination angles. The purpose of this review was to investigate the relationship between caput femoris posterior tilt of femoral neck fractures and surgical outcome, and to introduce a new method for measuring caput femoris posterior tilt of the femoral neck.

OBJECTIVE: To study the effect of ultrasound-guided fascia iliaca compartment block on perioperative analgesia and postoperative complications in geriatric patients with hip fractures. METHODS: A total of 127 elderly patients undergoing hip fracture surgery from January 2021 to September 2021 were randomized to receive ultrasound-guided continuous fascia iliaca compartment block(group F) either intravenous analgesia control group(group C). There were 62 cases in group F, including 19 males and 43 females with an average age of (82.4±7.2) years old ranging from 66 to 95 years old, involving 25 femoral neck fractures and 37 femoral intertrochanteric fractures. There were 65 cases in control group, including 18 males and 47 females, with an average age of (81.4±8.7) years old ranging from 65 to 94 years old, involving 29 femoral neck fractures and 36 femoral intertrochanteric fractures. The visual analogue scale(VAS), minimental state examination (MMSE), observer's assessment of alertness/sedation(OAA/S) scale, modified Bromage score, postoperative complications and general conditions during hospitalization in two groups were observed. RESULTS: The resting and exercise VAS at 30 min after block, anesthesia placement and 6, 24 and 48 h after surgery were lower than those in group C(P<0.05). In group F, MMSE scores at 12 h before surgery, and 1, 3 d after surgery and OAA/S scores at 3 d after surgery were higher than those in group C(P<0.05). The incidence of adverse effects and the number requiring additional analgesia were lower than those in group C(P<0.05). Group F had better perioperative analgesia satisfaction and hospital stay than group C(P<0.05). But there was no significant difference regarding Bromage score and 30-day mortality between two group(P>0.05). CONCLUSION Ultrasound-guided continuous fascia iliacus space block was safe and effective for elderly patients with hip fracture, and could significantly reduce perioperative pain, improve postoperative cognitive function, and reduce postoperative complications, thereby shortening hospital stay and improving the quality of life during hospitalization.

OBJECTIVE: To explore incidence, risk factors and the relationship between preoperative heart failure and prognosis in elderly patients with hip fracture. METHODS: A retrospective analysis was performed on 1 569 elderly patients with hip fracture treated from January 2012 to December 2019, including 522 males and 1 047 females, aged 81.00 (75.00, 90.00) years old;896 intertrochanteric fractures and 673 femoral neck fractures. Patients were divided into heart failure and non-heart failure groups according to whether they developed heart failure before surgery, and heart failure was set as the dependent variable, with independent variables including age, gender, fracture type, comorbidities and hematological indicators, etc. Univariate analysis was performed at first, and independent variables with statistical differences were included in multivariate Logistic regression analysis. Independent risk factors for preoperative heart failure were obtained. The length of hospital stay, perioperative complications, mortality at 30 days and 1 year after surgery were compared between heart failure and non-heart failure groups. RESULTS: There were 91 patients in heart failure group, including 40 males and 51 females, aged 82.00 (79.00, 87.00) years old;55 patients with intertrochanteric fracture and 36 patients with femoral neck fracture. There were 1 478 patients in non-heart failure groups, including 482 males and 996 females, aged 81.00(75.00, 86.00) years old;841 patients with intertrochanteric fracture and 637 patients with femoral neck fracture. There were significant differences in age, sex, coronary heart disease, arrhythmia and dementia between two groups(P<0.05). Multivariate Logistic analysis of statistically significant factors showed that males(OR=1.609, P=0.032), age(OR=1.032, P=0.031), arrhythmia(OR=2.045, P=0.006), dementia (OR=2.106, P=0.014) were independent risk factor for preoperative heart failure. The 30-day and 1-year mortality rates were 9.9% and 26.4% in heart failure group and 3.6% and 13.8% in non-heart failure group, respectively;and had statistical significance between two groups (P<0.05). There were significant differences in pulmonary infection, cerebrovascular complications and cardiovascular complications between two groups (P<0.05). The duration of hospitalization in heart failure group was (16.21±10.64) d compared with that in non-heart failure group (13.26±8.00) d, and the difference was statistically significant (t=2.513, P=0.012). CONCLUSION Male, old age, arrhythmia and dementia are independent risk factors for heart failure after hip fracture in elderly patients. Patients with preoperative heart failure have a higher incidence of postoperative pulmonary infection, cerebrovascular and cardiovascular complications, higher mortality at 30 d and 1 year after surgery, and longer hospital stay.

OBJECTIVE: To explore clinical effect of attaching locking plate with bone grafting based on retaining the original intramedullary nail in treating non-union after intramedullary nail fixation of long shaft fractures of lower limbs. METHODS: A retrospective study was conducted on 20 patients treated with non-union fractures after intramedullary nailing of long shaft fractures of lower limbs from June 2015 to June 2020. All patients were treated with the original intramedullary nailing and bone grafting from the iliac bone, and were underwent open reduction plate internal fixation and bone grafting for old fractures. Among them, 14 were males and 6 were females, aged from 35 to 56 years old with an average of (42.2±9.6) years old. Nine patients were femoral shaft fracture and 11 patients were tibial shaft fracture. According to characteristics of fracture end nonunion, 6 patients were stable/atrophic, 9 patients were unstable/large, and 5 patients were unstable/atrophic. The nonunion time ranged from 8 to 12 months with an average of(9.8±2.0) months after the initial surgery. Visual analogue scale (VAS), knee range of motion, bone healing time, complications and fracture-end healing were recorded before and at the latest follow-up. RESULTS: All patients were followed up for 18 to 48 months with an average of (36.3±10.5) months. The incision of all patients were healed at stageⅠwithout complications such as infection or internal fixation ruptur. Healing time of femur and tibia was (8.5±2.6) months and (9.5±2.2) months. Knee joint motion increased from preoperative (101.05±8.98) ° to postoperative (139.35±8.78) ° at the latest follow-up (t=-12.845, P<0.001). VAS decreased from preoperative (5.15±1.72) to postoperative (0.75±0.96) at the latest follow-up (t=11.186, P<0.001). CONCLUSION On the basis of retaining the original intramedullary nail, the addition of locking plate internal fixation and autogenous iliac bone grafting have advantages of simple operation, less trauma, fewer complications and high fracture healing rate. It is one of the effective surgical schemes for the treatment of nonunion after intramedullary nail fixation of long bone fracture of lower extremity.

A 19-year-old man had an accidental fall from the 2nd floor and sustained multiple injuries. On radiological evaluation, the patient had symmetrical quadruple limb involvement with bilateral humerus shaft, bilateral olecranon, bilateral femur shaft, and bilateral patella fractures. The patient was actively managed using damage control orthopaedics, and a sequence of skeletal fixation was planned based on the hemodynamic stability and periodical serum lactate assessment. Symmetrical quadruple limb fractures are very rare, which could be associated with higher mortality. A meticulous clinical evaluation, periodical blood parameter assessment and strict adherence to the principles of damage control orthopaedics can be conducive to prevent life-endangering complications.

OBJECTIVE: To retrospectively analyze efficacy of single structure internal fixation and double structure internal fixation in the treatment of ipsilateral femoral shaft and neck fracture, and analyze their indications. METHODS: From June 2015 to December 2020, 21 patients with ipsilateral femoral shaft and femoral neck fracture were treated, including 14 males and 7 females, aged 23 to 69 years old with an average of(38.1±12.9) years old. According to different femoral shaft fracture sites, some patients were fixed with cephalomedullary implant for both femoral neck and the femoral shaft(single structure, InterTan or PFNA Ⅱ), some patients were fixed with cannulated screws for the femoral neck and a retrograde locking nail for the femoral shaft (dual structure), and postoperative function and complications were recorded during follow-up. In 10 cases of single-structure fixation, the femoral necks were all basicervical fractures, and the femoral shaft fractures were located in the proximal isthmus;11 cases were double-structure fixation, 9 cases in 11 were basal type of femoral neck, 2 cases in 11 were neck type, and the femoral shaft fractures were located in the isthmus and the distal isthmus. RESULTS: All patients were followed up for 12 to 27 months. No femoral head necrosis, deformity, delay or nonunion occurred in the patients with single-structure fixation, and no delayed union or nonunion occurred in femoral shaft fractures;At the final follow-up, Harris score of patients with single-structure fixation was 91.8±4.1, with 8 cases were excellent and 2 cases were good. The fractures of patients with dual-structure fixation achieved good union without femoral head necrosis, except 1 case of femoral shaft fracture had delayed union;At the final follow-up, Harris score of patients with dual-structure fixation was 92.4±5.9, 7 cases were excellent, 3 cases were good, and 1 case was fair. CONCLUSION Good reduction and fixation is the key to the treatment of such fractures. Both the single-structure fixation and the dual-structure fixation are good methods, and it should be selected according to the locations of femoral shaft and femoral neck fractures. Single-structure fixation is a good choice for femoral shaft fractures located at the proximal isthmus and basal femoral neck fractures. For isthmus and distal femoral shaft fractures combined with ipsilateral femoral neck fractures, dual-structure fixation is recommended.
