Objective
Use of standardized cement augmentation of the proximal femur nail antirotation (PFNA) for the treatment of trochanteric fragility fractures, which are associated with high morbidity and mortality, to achieve safer conditions for immediate full weight-bearing and mobilization, thus, improving preservation of function and independency of orthogeriatric patients.Indications
Trochanteric fragility fractures (type 31-A1–3).Contraindications
Ipsilateral arthritis of the hip, leakage of contrast agent into the hip joint, femoral neck fractures.Surgical technique
Reduction of the fracture on a fracture table if possible, or minimally invasive open reduction of the proximal femur, i.?e., using collinear forceps if necessary. Positioning of guidewires for adjustment of the PFNA and the spiral blade, respectively. Exclusion of leakage of contrast agent and subsequent injection of TRAUMACEM? V+ into the femoral head–neck fragment via a trauma needle kit introduced into the spiral blade. Dynamic or static locking of the PFNA at the diaphyseal level.Postoperative management
Immediate mobilization of the patients with full weight-bearing and secondary prevention, such as osteoporosis management is necessary to avoid further fractures in the treatment of these patients.Results
A total of 110 patients older than 65 years underwent the procedure. Of the 72 patients available for follow-up (average age 85.3 years), all fractures healed after an average of 15.3 months. No complications related with cement augmentation were observed. Approximately 60?% of patients achieved the mobility level prior to trauma.3.
Background
Displaced fractures of the acetabulum involving the quadrilateral plate continue to be a surgical challenge. In this study, we describe our operation technique of auxiliary acetabular cerclage-wiring combined with plate osteosynthesis and present our results as well as short-term outcome.Patients and methods
All patients aged 18 years and older treated with auxiliary cerclage-wiring between 2007 and 2012 were included in this study. Fractures were classified according to Letournel. Cerclage wiring was used when reposition and retention of the fracture was insufficient with plates and screws alone. Short-term outcome was evaluated by the German Short Musculoskeletal Functional Assessment (SMFA-D) questionnaire.Results
Data from 23 patients were collected. The follow-up period was 7 months (range 2–23 months). Of the 23 patients, 22 showed excellent fracture reduction and retention. One patient had to undergo revision surgery due to loss of reposition. Patients showed good functional outcome.Conclusion
Auxiliary acetabular cerclage-wiring is a safe and effective method for fracture reduction and retention especially in displaced acetabular fractures involving the quadrilateral plate.4.

Objectives
We report the application of a new fixed angle plate (NCB DF®, Zimmer inc. USA, Warsaw, IN) in the treatment of periprosthetic femur fractures. The NCB DF® combines conventional plating technique with polyaxial screw placement and angular stability.Design
Prospective cohort study.Setting
A single level-1 trauma center.Patients
From May 2003 to December 2005, a total of 24 patients with periprosthetic femur fractures were treated. The NCB DF® femur plate was used in all cases. The average follow-up period was 12 months (3–31 months). Twelve patients had a periprosthetic fracture after total knee replacement (TKA) and 12 patients after total hip replacement (THA). The mean period from primary joint replacement to periprosthetic fracture was 8.2 years for the THA group and 7.2 years for the TKA group.Intervention
A combined conventional/locking surgical technique was performed in all the cases.Main outcome measures
Union, non-union, mal-union, duration of surgery, range of motion, postoperative mobility, subjective patient satisfaction and complications.Results
The union rate was 90%, the mal-union rate 5% and the re-operation rate 15%. Postoperative mobility reached the preoperative level in all but for two patients. Three complications occurred relating to the implant or the procedure: one fatigue failure of the plate (non-union), one screw breakage, and one wound infection.Conclusions
The NCB DF® combines conventional plating technique with polyaxial screw placement and angular stability. This combination technique shows promising results regarding union and mal-union rates in periprosthetic fractures in elderly and osteoporotic patients.5.

Purpose
Unified classification system (UCS) type B1 periprosthetic femoral fractures are associated with many complications, and management decisions continue to be controversial. The purpose of this study was to evaluate outcomes of UCS type B1 periprosthetic femoral fractures treated by locking compression plating with strut allograft augmentation.Materials and methods
We retrospectively reviewed 17 consecutive UCS type B1 periprosthetic femoral fractures treated by open reduction and internal fixation using a lateral locking compression plate supplemented with an anterior cortical strut allograft. There was one man and 16 women with an average age of 74 years (range, 57–92 years). All had a cementless hip arthroplasty, and eight of the arthroplasties were revisions.Results
The mean duration of follow-up was 28 months (range, 12–74 months). All 17 fractures healed successfully at a mean of 20 weeks (range, 12–30 weeks). The mean post-operative Harris hip score was 86 points (range, 77–95 points). No mechanical complications such as failure of plate or screws and malalignment were noted. According to the graft-remodeling classification of Emerson et al., a partial bridging was observed in nine and a complete bridging in eight. Two patients required a removal of the plate due to irritation of the iliotibial band. No femoral stem loosening or deep infection was observed.Conclusion
Our findings indicate that open reduction and internal fixation of UCS type B1 periprosthetic femoral fractures using a lateral locking compression plate supplemented with anterior cortical strut allograft provides adequate mechanical stability of fracture fixation and enhances the fracture healing.6.
Objectives
To present the experience of a tertiary referral hospital in the management of a case series with hip or knee fractures by using modular megaprosthesis.Patients and methods
Seventeen consecutive patients with highly comminuted fractures of the knee (n = 2), periprosthetic fractures of knee (n = 10) or hip (n = 5) were included. Fractures were managed with modular megaprosthesis (including total hip in 2 cases). Postoperative complications like infection and instability and outcome measures like return to previous mobility and living were recorded.Results
The mean age at time of surgery was 77 years (25–91), and mean follow-up was 44 months (13–98). We had no intra-operative complications. There were 3 deep periprosthetic infections, 1 hip and 2 knee. In the hip group, including total femur patients, we had 2 dislocations (2/7), both managed with closed reduction. No aseptic loosening was seen. 15/17 patients regained walking ability, and 16 were discharged to independent living. Nine patients have died at the time of follow-up.Conclusions
In these often old and physically compromised patients with highly comminuted fractures or complicated periprosthetic fractures, modular megaprosthesis could be a good surgical option. It can provide immediate stability and allow early mobilization.7.
Background
The number of patients with total hip replacement (THR) is likely to grow. Periprosthetic femoral fractures occur in 0.1–4.5 % of patients with THR. Treatment of periprosthetic fractures in the vicinity of well-fixed implants has focused on lateral plating. The purpose of this study was to evaluate polyaxial locking plate treatment of periprosthetic fractures with THR in regard to fracture type, surgical procedure, complications, and outcome.Methods
Between 2007 and 2013, 109 patients underwent surgical treatment for periprosthetic femur fractures with 66 fractures in the vicinity to a THR. Fifteen patients were excluded. Therefore, 51 patients with a mean age of 78.7 years were identified. There were 76.5 % females. Average BMI was 27.1 kg/m2. Follow-up averaged 25 months. Total hip stems were uncemented in 63 %. Low-energy mechanism predominated. Fractures were classified according to AO/OTA and Vancouver classifications with the majority (70.6 %) classified as AO/OTA type A fractures. Surgeries were performed utilizing a polyaxial locking plate. Complications were recorded concerning infection, union, fixation failure, and revision surgery.Results
After the index procedure, 90.2 % healed. Non-union formation was diagnosed in 5.9 % with 2.0 % leading to hardware failure. All patients with non-union formation had interprosthetic fractures (χ 2 = 0.016). Additionally, these fractures were classified as AO/OTA type B fractures (χ 2 = 0.003).Conclusions
Surgical management despite polyaxial locked plate fixation continues to be challenging and may still result in non-union formation. Non-union formation is increased in AO/OTA type B fractures and related to interprosthetic fractures.Level of evidence

Objective
Bony healing of dislocated distal radius fractures after open reduction and internal stabilization by locking screws/pins using palmar approach.Indications
Extraarticular distal radius fractures type A2/A3, simple extra- and intraarticular fractures type C1 according to the AO classification, provided a palmar approach is possible.Contraindications
Forearm soft tissue lesions/infections. As a single procedure if a volar approach not possible.Surgical technique
Palmar approach to the distal radius and fracture. Open reduction. Palmar fixation of the plate to radial shaft with single screw. After fluoroscopy, distal fragments fixed using locking screws.Postoperative management
Below-the-elbow cast for 2 weeks. Early exercise of thumb and fingers, wrist mobilization after cast removal. Complete healing after 6–8 weeks.Results
Ten patients averaged 100?% range of motion of the unaffected side after 43±21 months. No complications observed. DASH score averaged 12±16 points; Krimmer wrist score was excellent in 7, good in 2, and fair in one.9.
Objective
Operative stabilization is recommended even for non-displaced or only slightly displaced femoral neck fractures. In addition to the known osteosynthetic procedures, an angular stabile implant system (Targon® FN) has been established since 2006 for treatment of such fractures.Indications
Displaced femoral neck fractures (Garden III and IV) and non-displaced fractures (Garden I and II).Contraindications
Fractures close to the hip joint, which are not classified as typical medial femoral neck fractures and patients with advanced osteoarthritis of the hip who would profit from an endoprosthetic procedure.Surgical technique
The operative procedure is shown after fracture reposition and central positioning of the guide wire as a standard course.Postoperative Management
Early postoperative mobilization under guidance of a physiotherapist. Initially, partial weight bearing only in selected cases with severe displacement.Results
In our patients collective the Targon® FN has been implanted in over 100 cases. Revision indications and secondary endoprosthesis were documented in only 9?% of the cases. This angular stable screw osteosynthesis system is a safe procedure to achieve patient mobility if the indications are adhered to and implantation is correctly carried out.10.
Purpose
The purpose of this study was to investigate which factors predict the failure and success of treatment of periprosthetic type B humeral fractures that have occurred traumatically.Methods
The institutional admission database and the trauma registry were retrospectively reviewed. A total of 8 patients suffering from periprosthetic humeral fractures were included. The time span was 10 years (2000–2010).Results
The average age at the time of the fracture was 77 years. Surgery was performed at an average of 5.6 days after injury. In three patients with a well-fixed and one with an unstable humeral component, open reduction and internal fixation with the use of a plate and screws was performed. Two patients with a Delta prosthesis had an unstable humeral component. A proximal humeral resection and an implantation of an HMRS prosthesis was performed in one patient. The other patient received a Delta revision stem prosthesis, cable and plate fixation. Two patients were treated conservatively.Conclusions
Early surgical treatment with angular stable implants in fractures with a stable stem and replacement with a revision long-stem component in fractures with a loose prosthesis is recommended. Special attention should be paid to bone quality and anatomical proximity to the radial nerve. Conservative treatment of type B fractures is not sufficient to achieve union, especially in short oblique or transverse fractures.11.
Background
Acetabular fractures in the elderly and severely comorbid patient can be associated with high morbidity and mortality; however, differences in outcomes of acute ORIF versus non-operative care of acetabular fractures in a subgroup of elderly (>75 years) and/or severely comorbid younger patients (>65) remain unclear.Patients and methods
A retrospective review of 243 patients who sustained an acetabular fracture between April 2005 and November 2014 was performed. Eighty-seven patients met inclusion criteria: age > 75 with or without comorbidities or age > 65 if complicated by two or more medical comorbidities. Outcomes measures evaluated were 1-year mortality, duration of hospital stay, return to pre-injury ambulation status and treatment failure marked by conversion to a total hip arthroplasty (THA) within 1 year of treatment.Results
Thirty-seven patients with acetabular fractures were treated with surgical fixation, and 49 were treated non-operatively. Operative patients did not demonstrate a statistically significant difference in mortality within 1 year of treatment compared to non-operatively treated patients. Operative patients demonstrated a statistically significant increase in treatment failure marked by a conversion to a THA within 1 year when compared to conservatively treated patients. No differences in age, duration of follow-up, or ability to return to baseline at latest clinical follow-up were found between groups. However, non-operatively treated patients had a higher incidence of Alzheimer’s disease/Dementia and Parkinson’s compared to operatively treated patients.Conclusion
Analysis of our small cohort suggests that there may be a role for the non-operative treatment of acetabular fractures in this debilitated patient population despite a somewhat longer length of hospital stay at the time of injury. Conversion to THA was significantly higher at 1 year in our operated patients. No differences in mortality at 1 year were noted between patient groups. Return to baseline ambulation status was slightly higher in the non-operated group but not significantly so. However, a potential bias to more likely treat complex fractures operatively cannot be ruled out, as non-operative fractures were most often anterior column variants, usually more amenable to non-operative care.Level of evidence
Prognostic Level III.12.
Background
The treatment of periprosthetic femoral fractures is a great challenge for the orthopedic surgeon and requires a knowledge of bone fracture fixation as well as skills and experience in revision surgery. The aim of this retrospective study was to evaluate the functional and radiological outcomes of periprosthetic femoral fractures surgically treated in our department from 2010 to 2016.Materials and methods
This study involved 73 patients with a periprosthetic femoral fracture after total hip arthroplasty or hemiarthroplasty. Periprosthetic femoral fractures were classified using the Vancouver system. Functional outcomes were assessed using Harris hip score, Palmer Parker score, SF-36 score and ambulatory status. Radiological findings were classified using Beals and Tower’s criteria.Results
The mean age of patients was 79.6 years old. Local risks factors were identified in 67% of the patients, principally osteoporosis (63.0%), followed by osteolysis (26.0%) and loosening of the stem (8.2%). According to the Vancouver classification, there were 10 type A, 49 type B and 14 type C fractures. Of the type B fractures, 26 were B1, 17 were B2 and 6 were B3. Applying Beals and Tower’s criteria, radiological results were excellent in 24 patients (32.9%), good in 35 (47.9%) and poor in 14 (19.2%). The mean Harris hip score post-operatively was 72.5.Conclusions
These kinds of fractures should be assessed individually and the optimal treatment plan should be made in accordance with the bone stock quality, stem stability, location of the fracture and patient expectations.13.

Background
To test if complexity of acetabular fractures, pre-trauma health status, time from trauma to definitive surgery, severity of injury or job characteristics influence work resumption, return to the same professional position and time out of work.Materials and methods
We performed a retrospective study on patients with surgically treated acetabular fractures. Medical records were reviewed to analyse demographics, follow-up, diagnosis (Letournel classification), type of surgical treatment, co-morbidities, time from trauma to definitive surgery, American Society of Anesthesiologists physical status classification (ASA) and associated injuries. Patients were interviewed about the amount of leaves of absence and whether they returned to the same professional position.Results
The study included 108 patients whose mean age was 44 ± 11 years. Median time out of work was 180 days. Eleven patients lost their job and 23 patients returned to a different professional position. Univariable analysis showed: (a) the risk of losing the job was higher for patients who had been admitted to intensive care unit (ICU) (p = 0.018), (b) returning to the identical position was more likely in patients who were older (p = 0.006), sedentary workers (p = 0.003), and with shorter time from trauma to definitive surgery (p = 0.003). Multivariable linear regression showed that leaves of absence were longer in patients with higher ASA scores, who had been admitted to ICU, or were not sedentary workers.Conclusions
Work reintegration after acetabular fractures is a main issue for the patient and social systems: only 69 % of patients returned to their previously held professional position. Time out of work was not found to be related to fracture type but to pre-trauma health status, ICU admission and sedentary jobs.Level of evidence

Background
Thorough curettage and cement augmentation is the procedure of choice for treating giant cell tumor lesions, particularly those associated with large defects. Its association with pathological fractures has not been studied to a great extent, although a pathological fracture following a giant cell tumor is not a contraindication to treatment by curettage and cementation. We present our experience of bone cementation following intralesional curettage for treatment of giant cell tumors of the long bones of lower limbs with associated pathological fractures.Materials and methods
A total of 38 patients who had undergone a procedure in the weight-bearing long bones of lower limbs were included in the study. The age of the patients ranged from 18?79 years with a mean age of 38.57 years. The average follow-up was 102.42 months (8.5 years) ranging from 60?186 months (5?15.5 years). Results were based on serial radiographs showing consolidation of the lesion along with a subjective clinical examination and Enneking functional evaluation noted in the patient’s records.Results
Approximately 76 % of the lesions occurred around the knee. The results were graded as excellent (72 %), good (12.82 %) fair (10.25 %) and poor (5.12 %). Four cases developed a recurrence. Apart from a few documented complications, the lesions showed good consolidation and healed well.Conclusion
Giant cell tumors of the long bones of lower limbs with an associated pathological fracture at diagnosis can be managed with thorough curettage and cement augmentation of the bone defect with a satisfactory outcome.Level of evidence

Background
Periprosthetic distal femur fractures associated with total knee replacement are increasing in incidence. We hypothesized that a standardized management protocol would result in few implant failures and a low rate of postoperative complications.Methods
Retrospective observational cohort study at an urban level 1 trauma center and academic level 2 trauma center. Consecutive patients with periprosthetic distal femur fractures and stable total knee arthroplasty were included between January 1, 2011 and December 31, 2014. Patients were managed by a standardized protocol of co-management by a hospitalist service, fracture fixation within 24 h of admission by less-invasive locked bridge plating, and immediate unrestricted postoperative weight bearing. The primary outcome measure was the rate of postoperative complications. Secondary outcome measures included time to surgery, intraoperative blood loss, duration of surgery, length of hospital stay, time to full weight bearing, and time to radiographic fracture healing.Results
Fifty four fractures were treated in 52 patients. There were three implant failures, one deep infection, one nonunion and two patients with symptomatic malunion. One patient had knee pain due to patellar component instability associated with valgus alignment. There were ten thromboembolic complications despite consistent anticoagulation. Two patients died within 12 months of injury. Thirty-eight patients had returned to their pre-injury ambulation status at 1 year follow-up.Conclusion
A standardized approach of less-invasive locked plating fixation and immediate unrestricted weight bearing appears safe and feasible in the management of this vulnerable patient cohort.Trial registration number
This is a retrospective observational study without a Trial registration number.16.
Purpose
To select in a 2-year survey of proximal humerus fractures accessing the emergency department, a population of osteoporotic stable impacted fractures and to randomize them into two groups, one with an immediate intensive mobilization program and the other with an immediate conventional mobilization program.Methods
In emergency department, patients with clinical signs of shoulder girdle fracture were submitted to standard X-ray examination and CT scan. Patients with stable (absence of metaphyseal comminution or fifth fragment) osteoporotic (cortical bone thickness lower than 6 mm) impacted (Is any part of metaphysis or head impacted into the shaft? YES/NO) proximal humerus fractures were selected for randomization in one of the two groups. Group 1: early intensive mobilization; Group 2: early conventional mobilization. Functional and radiographic assessment was recorded at 3, 6 and 12 months of follow-up.Results
In the considered period, 120 patients were affected by a stable impacted osteoporotic proximal humerus fracture. At the final follow-up, 36 patients in group 1 and 39 patients in group 2 were available for statistical analysis. Functional and radiographic scores were comparable, with a trend of significance in favor of group 2. No fracture in any of the group showed significant loss of reduction respect to 6 months of follow-up. 4 (10%) and 1 (2.5%) patients in groups 1 and 2 were not compliant with the rehabilitation program (p = 0.037).Conclusions
This randomized controlled trial showed that impacted osteoporotic proximal humerus fractures can be managed non-operatively with an early conventional rehabilitation program composed by 10 sessions of passive motion twice a week, followed by recovery of active range of motion for further 10 sessions thrice a week, while no advantage is given by a more aggressive rehabilitation regimen. Self-assisted exercises should be explained to patients to maximize the effects of the assisted program.Level of evidence
Level 1, randomized controlled double-blinded trial.17.
Background
The femoral neck fracture is one of the most common fractures in the elderly. A variety of methods and approaches are used to treat it. Total hip arthroplasty is a preferred approach in independent, mobile, elderly patients, given its more favorable long-term outcome.Our hypothesis is that the direct anterior approach in geriatric trauma patients has a lower dislocation-rate with the advantage of early recovery due to a muscle sparing approach and therefore early possible full weight-bearing.Methods
Patients were retrospectively sought who suffered a femoral neck fracture from 2008 to 2013. All patients were treated through a direct anterior approach and using the same brand of implants. Medical history, standardized physical exam, conventional pelvic plain and axial hip x-rays, Harris Hip Score, Merle D'Aubigné and Postel and SF-36 were assessed.Results
Eighty-six patients were included in the study with a mean age of seventy-five years. The mortality rate was 16.7 %. Complications were encountered in nineteen patients (22.0 %) who needed operative revision and one postoperative complication (1.2 %) which could be handled conservatively. There were five intraoperative complications (5.8 %), two dislocations (2.3 %), one aseptic loosening in a non-cemented stem (1.2 %), six periprosthetic fractures in non-cemented stems (6.9 %), one displacement of a non-cemented cup (1.2 %), two early infections (2.3 %) and three hematomas (3.5 %) recorded.Conclusions
Although the direct anterior approach is associated with a rather long learning curve we have found it to preserve the soft-tissues with no injury to abductors. It therefore shows an early advantage in elderly patients in terms of early recovery and therefore early possible full weight-bearing. Fracture treatment with dual mobility cups might lead to lower dislocation rates, but are associated with higher costs. Due to higher complication rates in non-cemented versus cemented shafts, we have changed our practice towards favoring cemented femoral stems in patients with suspected or manifest osteoporosis.18.
Purpose
The purpose of this study was to investigate the clinical outcomes of femoral fracture with implants on the proximal and distal sides to verify whether actual fracture morphologies follow the fracture types of Baba classification focusing on implant designs useful for periprosthetic femoral fracture.Methods
Prosthesis was present in 85 with periprosthetic femoral fractures. Excluding 73 patients with fracture around the femoral stem or fracture of the TKA femoral component alone, 12 patients with 14 legs with both implants were investigated. All patients were radiographically assessed for implant stability according to the Baba classification. For clinical evaluation, intra- and postoperative complications, the operation time, and intra-operative blood loss were investigated.Results
The Baba classification fracture type showed the implant as unstable and stable types in 3 and 11 legs, respectively. The consistency rate between the Baba classification-based judgment of plain radiograms acquired at the time of injury and actual surgical findings was 100%. As a result of treatment according to the Baba classification, bone union was achieved in all patients. There were no intra- or postoperative complications.Conclusions
Applying the Baba classification, implant stability could be sufficiently evaluated in not only periprosthetic femoral fractures following hip arthroplasty, but also interprosthetic femoral fractures, thereby verifying its usefulness in setting the treatment strategy.19.
