Project description:BackgroundExtramedullary and intramedullary implants have improved in recent years, although consensus is lacking concerning the definition and classification of unstable intertrochanteric fractures, with uncertainties regarding treatment.Questions/purposesWe conducted a national survey of practicing chairpersons of German institutions to determine current perspectives and perceptions of practice in the diagnosis, management, and surgical treatment of unstable intertrochanteric fractures.MethodsBetween January and February 2010, we emailed 575 German chairpersons of trauma and/or orthopaedic departments, asking them to complete a 26-question web-based survey regarding three broad domains: fracture classification and instability criteria, implants and surgical treatment algorithms, and timing of operations. Response rate was 42%.ResultsThere was a clear preference for use of the AO/OTA fracture classification with geographic variations. Absence of medial support was considered the main criterion for fracture instability (84%), whereas a broken lateral wall and detached greater trochanter were considered by 4% and 5% of the respondents, respectively, to determine instability. Two percent routinely fixed unstable intertrochanteric fractures with extramedullary devices. Ninety-eight percent of German hospitals reportedly perform surgery within 24 hours after admission. Time to surgery was dependent on hospital level, with more direct surgeries in Level I hospitals.ConclusionsDespite varying opinions in the literature in recent years, we found some instability criteria (lateral wall breach, a detached greater trochanter) played a minor role in defining an unstable intertrochanteric fracture pattern. Despite recent meta-analyses suggesting clinical equivalence of intra- and extramedullary implants, few respondents routinely treat unstable intertrochanteric fractures with extramedullary plates. Additional studies are required to specify the influence of fracture characteristics on complication rate and function and to establish a classification system with clear treatment recommendations for unstable intertrochanteric fractures.

Project description:PurposeTo find out whether the intramedullary fixations are superior to the extramedullary fixations in treating unstable femoral intertrochanteric fractures (UFIFs).MethodsThe meta-analysis of randomized controlled trials (RCTs) was conducted by searching the PubMed, Cochrane Library, and Embase databases to evaluate functional scores, surgical outcomes, and adverse events in adult patients receiving intramedullary fixations in comparison to extramedullary fixations. Risk ratio (RR) or weighted mean difference (WMD)/standard mean difference (SMD) with 95% confidence intervals (CIs) were calculated as effect sizes.ResultsA total of 18 RCTs, comprising 2414 patients, were included in this meta-analysis. Primary efficacy outcome: Parker scores [weighted mean difference, 1.10, 95% confidence interval (CI), 0.64-1.55; P < .0001] and Harris hip scores [risk ratio, 1.24, 95%CI, 1.09 -1.41; P = .0008] were higher in the intramedullary fixation group. Moreover, blood loss, operative time, length of incision, hospital stay, and implant failure were superior in the intramedullary fixation group. Other secondary efficacy outcome: No significant differences were found between the 2 groups in terms of fluoroscopy time, mortality, cut-out, nonunion, superficial wound infection, later fracture, and reoperation.ConclusionsThis meta-analysis suggested that intramedullary fixation is more effective and safer than extramedullary fixation in treating UFIFs. Furthermore, blood loss, operative time, length of incision, hospital stay, and implant failure were superior in the intramedullary fixation group.

Project description:In this network meta-analysis, we determined the optimal surgical method for treating unstable femoral intertrochanteric fractures. We searched the EMBASE, Cochrane Library and Medline databases for studies evaluating sliding hip screws (SHS), gamma nail (GN) or proximal femoral nail antirotation (PFNA) methods, and included nine randomized controlled trials that met the inclusion criteria. Our analysis showed no differences in the rates of complications between SHS and PFNA relative to GN (p > 0.05). However, the surface under the cumulative ranking curve (SUCRA) score for PFNA (77.6%) was higher than the SUCRA scores for GN (65%) and SHS (7.5%). This suggests PFNA is the better surgical method than GN or SHS for unstable femoral intertrochanteric fractures.

Project description:BackgroundHip fractures usually occur in old aged patients with osteoporotic bone. Management of hip fractures in old aged patient is aimed to ambulate patient immediately and to restore the pre-operative ambulation. Proximal femur replacement is an effective treatment option in elderly patient with osteoporotic bones. It allow immediate weight bearing and early return to preoperative ambulatory status and minimizes the chances of systemic complication associated with prolong bed rest associated with internal fixation. This study is aimed to review the outcome of the patients whom underwent proximal femur replacement as primary treatment for the patient with comminuted intertrochanteric and sub trochanteric fracture.Patients and methodThis is a study conducted in our university hospital which is a tertiary-care level-1 trauma center. A retrospective analysis of 21 patients who underwent proximal femur replacement for comminuted intertrochanteric and sub trochanteric fracture, age more than 60 years during the period from April 2011 to March 2018 was conducted. Data collected included: age, gender, comorbidities, mechanism of injury, type of fracture, functional outcome (calculated via Harris Hip Score) and one year mortality.ResultsThe mean age of the patients was 74.05(range 64-91) years, out of which 13 (61.8%) were female and 8 (38.0%) were male. The mean follow up was 32.6(8-91 months).Immediate post-operative ambulation status was full weight bearing (FWB) in 17 patients (80.9%) of the patients while three patients (19.0%) had non-weight bearing (NWB) due to associated co-morbidities. The mean preoperative Harris Hip score was 68.0, while the mean postoperative Harris Hip score was 66.5 at last follow up. Post operatively one patient (4.7%) developed pulmonary embolism, one patient developed dislocation. One patent (4.7%) died of sepsis from implant infection at 8 months after surgery.ConclusionPrimary Proximal femoral replacement in a viable option in old aged patients with poor bone quality who developed intertrochanteric and subtrochanteric fracture. According to our study, with mortality rate comparable to that of primary fixation, yet with the added advantage of immediate post op ambulation and reduced incidences of decubitus ulcers, atelectasis and DVT.

Project description:BackgroundTibiotalocalcaneal (TTC) intramedullary nailing has been suggested as an alternative to open reduction and internal fixation (ORIF) for the primary treatment of unstable fragility ankle fractures with a poor soft tissue envelope. This study aims to investigate the clinical efficacy of TTC intramedullary nail fixation for the primary treatment of unstable ankle fractures in frail elderly patients with poor soft tissue condition, by assessing the number of postoperative complications and the patient-reported functional outcomes.MethodsA retrospective cohort study was performed including patients with an unstable ankle fracture treated between 2015 and 2019 with TTC stabilization using a retrograde intramedullary hindfoot nail that was inserted without joint preparation and allowing immediate weight-bearing postoperatively. The primary outcome was the total number of postoperative complications.ResultsA total of 10 patients were included out of 365 operatively treated ankle fractures. The mean age was 85.2 years (range 66-92) with a mean follow-up of 11.2 months (range 6-16). Fracture types included AO/OTA 44-B2 (n = 1), 44-B3 (n = 6), 44-C1 (n = 2) and 44-C3 (n = 1). Postoperative complications were observed in 4 patients (40%), including 3 nonunions, 2 implant related complications and 1 wound infection. No wound healing disorder or below-the-knee amputation was observed. Four patients (40%) deceased between post-operative 6 to 16 months due to medical conditions unrelated to surgery. The mean Foot and Ankle Outcome Score was 52.6 (range 44.2-73.8).ConclusionHindfoot nailingis a viable treatment option in selected high-risk patients with an advanced age, unstable ankle fractures with significant bone loss, poor soft tissue condition and/or severely impaired pre-injury mobility. In a frail geriatric population, hindfoot nailing may be a safe alternative fixation method with a low risk of wound complication or major amputation. However, unprepared joint may lead to symptomatic nonunion after TTC intramedullary nailing.

Project description:ObjectiveUnstable femoral neck fractures are typically high-angled shear fractures caused by high-energy trauma. Internal fixation of femoral neck fractures with placement of parallel cannulated screws in an inverted triangle configuration is commonly performed in the clinical setting. This study was performed to investigate the primary results of intramedullary nailing with cannulated screws for the treatment of unstable femoral neck fractures in young and middle-aged patients.MethodsIn total, 96 consecutive patients with no history of hip surgery using inverted triangular cannulated compression screws or construction nails with cannulated screws were reviewed. Their demographic and radiological data were retrospectively collected from our institutional database.ResultsInverted cannulated screws had an excellent effect on decreasing the blood loss volume and incision size, but intramedullary nails exhibited superior advantages in decreasing screw exit and shortening the hospital stays. The Harris hip scores were comparable between the two groups.ConclusionsIntramedullary fixation with cannulated screws has advantages in treating complicated femoral neck fractures. Besides cannulated screws, intramedullary fixation with cannulated screws might be another method to treat unstable femoral neck fractures in young and middle-aged patients. The study was registered in ClinicalTrials.gov. Unique Protocol ID: 11156458. The ClinicalTrial number is NCT03550079.

Project description:We present a patient with bilateral Rorabeck II/Su III periprosthetic distal femur fractures treated successfully with bilateral single stage flexible intramedullary fixation. Flexible intramedullary fixation of Rorabeck II/Su III periprosthetic distal femur fractures provides the benefits of shorter operative time, lower blood loss, and preservation of bone stock compared to plate fixation and distal femur replacement. We suggest that for patients with similar injuries flexible intramedullary fixation can be a viable treatment option.

Project description:Twenty patients with intertrochanteric fractures of the femur were treated by external fixation. They were selected because of their surgical risk and evaluated clinically and radiographically after 6,12 and 18 weeks. Fourteen out of twenty patients had excellent results. Caxa vara deformity, shortening and delayed union was observed in two patients. Results indicate that external fixation is a useful method for treatment of these type of patients.

Project description:IntroductionStable reduction and rigid fixation of the sacrum and posterior ring structures are of paramount importance in the management of complex pelvic ring disruptions, Tile B and C. The major concern with the use of conventional methods, like iliosacral screws and iliolumbar fixations is the increased risk for surgical and implant-related morbidity, especially in difficult situations, such as comminuted, bilateral sacral fractures, and fractures in the dysmorphic sacrum. Although various biomechanical studies have reported the posterior trans-iliac plates to provide maximum resistance to distracting forces by the principle of tension band, the literature pertaining to this implication in clinical studies has been limited. The purpose of our study was to assess the efficacy of the trans-iliac plate in the management of unstable sacral fractures and its utility in pelvic disruptions associated with surgical site morbidity.MethodologyThe patients with unstable pelvic fractures (Tile B and C) between 2013 and 2017 were retrospectively analyzed at a trauma center. First, the anterior ring disruptions were stabilized, and then, the sacral fractures (Denis Zone 1-3) treated by posterior tension band plate osteosynthesis (3.5 mm reconstruction plate) were included. Demographic and perioperative data were assessed. The outcome variables studied were surgical morbidity, pain, loss of reduction, and union and implant-related complications. The outcomes were graded using Lindhal's (radiological) and Majeed (functional assessment) scores.ResultsThirteen patients (nine male/four female) with a median age of 42 years, had sacral fractures in Denis zones 1/2/3 (four/ten/one, respectively), resulting from Tile pelvic injury B and C were included. The pelvis in five patients was stabilized only with the posterior plate due to the anteriorly-associated surgical site morbidity (Morel-Lavallee lesions and urinary tract injuries). The mean follow-up was 21.5 ± 2.8 months. All fractures had a radiological union by 22 weeks; Lindhal's grade A in ten patients and grade B in three patients. Two out of three patients recovered from preoperative neurological involvement. Two had complained of implant prominence (BMI<19 kg/m2) and there were no implant failures. Four had excellent, six had good, and three had fair or poor functional outcomes.ConclusionThe posterior trans-iliac plate is a minimally invasive and safe procedure that can be used in a wide range of unstable sacral fractures with notably less implant failure rate. The rigid posterior construct restores the principle tension between the iliac blades and minimizes the secondary displacement of the anterior disrupted structures, thereby useful in managing ring disruptions with surgical site morbidity.

Project description:ObjectiveTo introduce the clinical features of and surgical techniques for a rare type of irreducible pertrochanteric femur fracture pattern with bisection of the lesser trochanter.MethodsFrom January 2017 to December 2019, 357 patients with per/intertrochanteric femur fractures underwent surgery by closed reduction and internal fixation, of whom 12 patients were identified with rare preoperative imaging features, the lesser trochanter was almost equally bisected. The main fracture pathoanatomy of these cases included: The anterior fracture line passed along the intertrochanteric line to the medial lesser trochanter and bisected it into 2 equal parts from mid-level of the lesser trochanteric protrusion. The proximal part of the lesser trochanter connected to the head-neck fragment and attached by the psoas major tendon, while the distal part of the lesser trochanter connected to the femoral shaft and attached by the tendon of the iliac muscle. These fractures were irreducible by a closed maneuver and were reduced with limited assistance by some devices, and short intramedullary nails were used for fixation of these fractures.ResultsAll patients were followed up for an average of 14.2 ± 2.1 months. Clinical fracture union occurred at an average of 10.8 ± 1.5 weeks, while radiographic union occurred at an average of 12.7 ± 1.2 weeks. No cut out of the helical blade was visible on radiographs. The average Parker-Palmer score was 6.9 ± 1.3 (range, 5-9) at the last follow up, including 8 cases rated as excellent, 2 as good and 2 as fair.ConclusionTwo-part pertrochanteric femur fractures with bisection of the lesser trochanter have an irreducible fracture pattern with cortical locking and soft tissue incarceration. Soft tissue release and short cephalomedullary nail fixation for this fracture pattern provide stable fixation and allow early exercise. This treatment appears to have excellent outcomes in the short and medium terms.
