Abstract
Preparation of the femoral proximal medullary cavity by reaming is essential for intramedullary nail osteosynthesis and hip revision arthroplasty. The use of reamers sometimes exerts high torsional forces on the bone. Design and direction of rotation of the reamer are potential influencing factors. The aim of this biomechanical study is to evaluate the best combination of a right- or left-cutting reamer with a clockwise- or counterclockwise-rotating insert in terms of preparation and safety. Right- and left-cutting reamers with conical design were each introduced into five synthetic femurs in both clockwise and counterclockwise rotation with constant feed force. A specially constructed test system was used for this series of tests, with which the respective intramedullary channel were reamed step by step. This was then used to determine the required torque. In addition, the feed rate measurement was analyzed using a modified digital caliper. The feed rates of the reamers with rotation in the same direction as the cutting direction were significantly increased compared to rotation in the opposite cutting direction (CCRLC vs. CCRRC 76.8 ± 9.0 mm/s vs. 25.2 ± 8.3 mm/s and CRRC vs. CRLC 54.3 ± 12.3 mm/s vs. 19.3 ± 0.6 mm/s; p < 0.01). In contrast, the mean torque during the reaming process was identical in all four groups. When preparing the proximal femoral medullary cavity, especially in cases with fragile bone structure, the available reamers should be introduced in opposite rotation to the cutting direction to achieve a more controllable feed of the reamer. Left-cutting reamers represent an alternative, using them in the usual clockwise-rotating technique to reduce the risk of complications during reaming.

J Orthop Surg Res 2023; 18:808. [PMID: 37898779 PMCID: PMC10613360 DOI: 10.1186/s13018-023-04300-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Accepted: 10/18/2023] [Indexed: 10/30/2023] Open
Abstract
OBJECTIVES The primary objective of the current study is to assess which is better for obtaining the proper femoral rotation during IMN of femoral fractures, the radiological or clinical method. The secondary objectives were to document malrotation's incidence and its effect on the hip and knee functional outcomes. METHODS Thirty-three patients with unilateral femoral shaft fractures were treated using intramedullary nails (IMN) on a usual radiolucent operative table. Intraoperative rotation adjustment was performed using a radiological method (relying on the contralateral lesser trochanter profile) in 16 patients (group A), while in 17 patients, a clinical method was used (group B). Postoperative assessment of malrotation was performed using a CT scan, and 15 degrees was the cutoff value where below is an acceptable rotation (group I) and above is true malrotation (group II). Functional assessment was performed using the Harris hip score (HHS), the Tegner Lysholm Knee Scoring Scale (TLKSS), and the Neer score. RESULTS The patients' mean age was 30.7 ± 9.3 years; 81.8% were males, and the left side was injured in 63.6% of patients. After a mean follow up of 18.2 ± 6.9 months, all fractures were united, and the overall mean amount of rotational difference between the fractured and the contralateral side was 14.7° ± 6.0 (3-29.4), 84.8% were in external rotation. No difference in the mean rotational deformity in group A compared to group B. Measurements were 13.9 ± 6.7 and 15.7 ± 5.5, respectively (p = 0.47). Seventeen (51.5%) patients in group I with a mean deformity of 9.8 ± 3.4 (3-14.7), while group II consisted of 16 (48.5%) patients with a mean deformity of 19.6 ± 3.7 (15.3-29.4). There was no difference in the functional scores between group I and group II; HHS was 89.4 ± 7.4 versus 87.7 ± 8.9 (p = 0.54), TLKSS was 84.6 ± 9.6 versus 80.4 ± 13.9 (p = 0.32), and Neer score was 87.9 ± 9.5 versus 83 ± 12.5 (p = 0.21) for group I and group II, respectively. CONCLUSION There was no difference in malrotation incidence after unilateral femoral fractures IMN with either an intraoperative clinical or radiological method for rotational adjustment; furthermore, malrotation did not affect the functional outcomes.

Abstract
Intramedullary reaming has been proven to be a safe and effective method for enhancing the union rates of long bone fractures. However, there is a risk of equipment failure, which can lead to severe complications. We present two cases of reamer failure during femoral nailing which illustrate the rare occurrence of intraoperative instrument failure. Our report also underscores the importance of routinely inspecting reaming equipment and provides technical insights to reduce the risk of failure.

Abstract
Aim: The aim of this study a retrospective comparison was the clinical and radiological results results of patients with femoral shaft fracture made oftreated with three different types of intramedullary nail (IMN).
Material and Method: The study included 54 patients operated on in our clinic because of femoral shaft fracture. The records were retrospectively examined of 18 patients applied with locked IMN (LIMN), 17 with blade expandable IMN (BEIMN), and 19 with talon distalfix IMN (TDIMN). The groups were compared statistically in respect of age, gender, BMI, affected side, operating time (mins), radiation exposure (number of shots), time to union (weeks), visual analog scale (VAS) score, soft tissue problems associated with implant irritation, amount of shortening (mm), coronal, sagittal and torsional angulation (degrees).
Results: The mean VAS score of the TDIMN group was determined to be statistically significantly higher than that of the LIMN and BEIMN groups (p=0.008, p=0.045). The operating times were similar in the BEIN and TDIMN groups (p=0.768) and significantly shorter than in the LIMN group (p

Abstract
OBJECTIVE To determine if reamed intramedullary nailing (IMN) of tibial and femoral shaft fractures exacerbated the hypercoagulable state of COVID infection, resulting in increased thromboembolic and pulmonary complications. DESIGN Retrospective chart review. SETTING Eleven Level I trauma centers. PATIENTS From January 1, 2020, to December 1, 2022, 163 patients with orthopaedic trauma and COVID positivity and 36 patients with tibial and femoral shaft fractures were included. INTERVENTION Reamed IMN. MAIN OUTCOME MEASURES Incidence of postoperative thromboembolic and respiratory complications. RESULTS Thirty-six patients with a median age of 52 years (range, 18-92 years; interquartile range, 29-72 years) met criteria. There were 21 and 15 patients with femoral and tibial shaft fractures. There were 15 patients sustaining polytrauma; of which, 10 had a new injury severity score of >17. All patients underwent reamed IMN in a median of 1 day (range, 0-12 days; interquartile range = 1-2 days) after injury. Two patients developed acute respiratory distress syndrome (ARDS) and 3 pneumonia. No patients had pulmonary embolism, deep vein thrombosis, or died within 30 days. CONCLUSION In this multi-institutional review of COVID-positive patients undergoing reamed IMN, there were no thromboembolic events. All patients developing pulmonary complications (ARDS or pneumonia) had baseline chronic obstructive pulmonary disease, were immune compromised, or sustained polytraumatic injuries with new injury severity score of >20. Given this, it seems reasonable to continue using reamed IMN for tibial and femoral shaft fractures after evaluation for COVID severity, comorbidities, and other injuries. LEVELS OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Does nail size or difference between canal and nail diameter influence likelihood of union or time to union of femoral shaft fractures treated with intramedullary nailing? A retrospective cohort study. BMC Musculoskelet Disord 2022; 23:826. [PMID: 36045444 PMCID: PMC9429295 DOI: 10.1186/s12891-022-05781-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Accepted: 08/25/2022] [Indexed: 11/26/2022] Open
Abstract
Background This study aims to determine whether nail size or the difference between canal and nail diameter (CN difference) affects the union rate and time of femoral shaft fracture treated with an interlocking intramedullary nail (IMN). Methods This was a retrospective review of 257 patients with femoral shaft fractures treated with IMN at a tertiary trauma medical center. All the IMN inserted were the same (Stryker T2 Femoral Nail). The patients were divided into groups based on nail size (10-, 11-, 12-, or 13-mm) and CN difference (< 1, 1–2, or > 2 mm), and union rate and time to union were compared. Results The 10-, 11-, 12-, and 13-mm groups based on nail size had 113, 74, 54, and 16 patients, respectively. The overall union rate was 97% (257/265). No significant differences in union rate or time to union were observed among these 4 groups. The groups based on CN differences of < 1-, 1 to 2, and > 2 mm comprised 143, 79, and 35 patients, respectively. Again, no significant differences were noted in union rate or mean time to union among the groups. Conclusions Similar union rate and time to union were observed, regardless of nail size or CN difference. This finding indicates that most simple femoral shaft fractures can be treated with a standard, reamed 10-mm IMN. A larger nail insertion is unnecessary and presents more risks; comparatively, the use of a small nail with less reaming is simpler, requires shorter operative times, results in less blood loss, and is less expensive.

Abstract
INTRODUCTION Treatment of severe open femoral fractures with retrograde intramedullary nailing, raises concerns of septic arthritis of the knee due to its intra-articular entrance point. There is little evidence concerning the safety of retrograde femoral nailing (RFN) usage in these cases, and what evidence there is does not necessarily include severe open fractures. Furthermore, the outcome of ballistic injuries treated in this manner and a comparison with antegrade femoral nailing (AFN), is yet to be established. The aim of this study was to examine the outcome of primary retrograde femoral nailing in high-grade open fractures and compare our results with similar fractures treated with AFN. PATIENTS AND METHODS A retrospective analysis of treated high-grade open femoral fractures, was performed at an academic level one trauma centre between 2006 and 2016. Included were all open femur shaft fractures treated with either RFN or AFN as primary fixation. We analysed both patient groups and compared outcomes including the infection rate, non-union rate and secondary interventions. Presence of knee pain and long-term function, was evaluated using the Short-Form 12 (SF-12) questionnaire. RESULTS Forty-nine patients with open femoral shaft fractures whose primary treatment was intramedullary nailing (IMN), were included in the cohort. Thirty patients were treated with RFN and 19 with AFN. No septic arthritis of the knee was detected in either group. One patient in the RFN group and two in the AFN had a deep surgical wound infection. Excluding reoperations for locking screw removal due to local irritation, the reoperation rate was 22% with two patients treated for non-union in the RFN group and two in the AFN. When comparing outcome measures, including SF-12 scores and the reported knee pain rates of AFN and RFN groups, no significant differences were observed. CONCLUSION Our study showed that retrograde femoral nailing as initial definitive treatment in high-grade open femoral shaft fractures, resulted neither in septic arthritis of the knee nor in an unacceptable infection rate. General outcomes regarding complications and reoperations, was similar to antegrade femoral nailing performed in our centre for similar injuries.

Abstract
PURPOSE To compare reamed intramedullary nailing (RIM) versus un-reamed intramedullary nailing (URIM) for the treatment of impending and pathological fractures of the humeral shaft in terms of 24-h postoperative pain, blood transfusion requirements, surgical time, surgical complications, medical complications, length of stay and consolidation rates. METHODS A retrospective comparative study between January 2013 and December 2018 was conducted. Student's t test, Mann-Whitney U and Chi-square tests were used to detect differences within the two study groups. Multiple linear regression was done to adjust for possible confounders. RESULTS A total of 53 patients (33 RIM vs. 20 URIM) underwent humeral nailing. Fifteen (28%) were impending fractures (7 RIM vs. 8 URIM). Multiple myeloma (49%) and metastatic carcinoma (39.6%) were the most common etiologies. Pain score (5.13 ± 0.68 RIM vs. 6.78 ± 0.62 URIM; p = 0.082) and total dose of opioids (33.125 ± 27.6 RIM vs. 33.3 ± 22.28 URIM; p = 0.462) showed similar results. Blood transfusion was more prevalent within RIM group (34.48% RIM vs. 20% URIM; p = 0.044) with a clinical tendency of higher blood loss (207.86 ± 150.83RIM vs. 127.00 ± 179.98 URIM; p = 0.092). There was a consolidation rate of 71.05% (27/38) with no statistical difference (73.08% (19/26) RIM vs. 66.67% (8/12) URIM; p = 0.685). CONCLUSION Our study suggests possible benefit of URIM in terms of less blood transfusions with no difference in consolidation rates. Even though without significance, a tendency to less blood loss, less events of systemic complication and lower length of stay was observed with URIM. Despite its limitations, this study can be used to design future prospective ventures that quantify patient-reported outcomes and provide more clear evidence.

Abstract
INTRODUCTION Open tibial fractures are the most common open long bone fracture, despite this, the management of these complex injuries still remains a topic of discussion amongst orthopaedic surgeons. SOURCES OF DATA We searched the EMBASE, MEDLINE and Google Scholar and a systematic review of 7500 articles, leaving 23 after exclusion criteria were applied, in order to analyse the management of open tibial fractures. AREAS OF AGREEMENT AND CONTROVERSY Infection was noted to be the most significant concern amongst authors, with definitive external fixation having a high rate of superficial pin-site infection and internal fixation having a high deep infection rate. GROWING POINTS It is essential to have a combined ortho-plastic approach to the management of these fractures as muscle flaps were the most common form of soft tissue coverage. AREAS TIMELY FOR DEVELOPING RESEARCH A national pragmatic trial into the management of open tibial fractures is required looking at fixation methods and soft tissue coverage, with at least a 2-year follow-up in order to ascertain the most appropriate management of these fractures and patient-related outcomes.

Abstract
INTRODUCTION Intramedullary nailing is generally accepted as the first choice for the treatment of diaphyseal fractures of femur and tibia, with a gradual incease in the use of unreamed nails. Different studies during last years show controversial outcomes. Some authors strongly favor unreamed nailing, but most of the authors conclude that reamed nailing have proved to be more successful. MATERIAL AND METHODS This study simulates unreamed intramedullary nailing of four femoral and three tibial fracture types by means of Finite Element (FE) models, at early postoperative stages with a fraction of physiological loads, in order to determine whether sufficient stability is achieved, and if the extent of movements and strains at the fracture site may preclude proper consolidation. RESULTS The behavior observed in the different fracture models is very diverse. In the new biomechanical situation, loads are only transmitted through the intramedullary nail. Mean relative displacement values of fractures in the femoral bone range from 0.30 mm to 0.82 mm, depending on the fracture type. Mean relative displacement values of the tibial fractures lie between 0.18 and 0.62 mm, depending on the type of fracture. Concerning mean strains, for femoral fractures the maximum strains ranged between 12.7% and 42.3%. For tibial fractures the maximum strains ranged between 10.9% and 40.8%. CONCLUSIONS The results showed that unreamed nailing provides a very limited mechanical stability, taking into account that analyzed fracture patterns correspond to simple fracture without comminution. Therefore, unreamed nailing is not a correct indication in femoral fractures and should be an exceptional indication in open tibial fractures produced by high-energy mechanism.

Abstract
Background: Femur is the most fractured long bone in the body that often necessitates surgical fixation; however, data on the impact of the mechanism of injury (MOI), age, and timing of intervention are lacking in our region of the Arab Middle East. We aimed to describe the patterns, management, and outcome of traumatic femoral shaft fractures. Methods: A retrospective descriptive observational study was conducted for all trauma patients admitted with femoral shaft fractures between January 2012 and December 2015 at the only level 1 trauma center and tertiary hospital in the country. Data were analyzed and compared according to the time to intervention (intramedullary nailing; IMN), MOI, and age groups. Main outcomes included in-hospital complications and mortality. Results: A total of 605 hospitalized cases with femur fractures were reviewed. The mean age was 30.7 ± 16.2 years. The majority of fractures were unilateral (96.7%) and 91% were closed fractures. Three-fourths of fractures were treated by reamed intramedullary nailing (rIMN), antegrade in 80%. The pyriform fossa nails were used in 71.6% while trochanteric entry nails were used in 28.4%. Forty-five (8.9%) fractures were treated with an external fixator, 37 (6.1%) had conservative management. Traffic-related injuries occurred more in patients aged 14–30 years, whereas fall-related injuries were significantly higher in patients aged 31–59. Thirty-one patients (7.8%) had rIMN in less than 6 h post-injury, 106 (25.5%) had rIMN after 6–12 h and 267 (66.8%) had rIMN after more than 12 h. The implant type, duration of surgery, DVT prophylaxis, in-hospital complications, and mortality were comparable among the three treatment groups. Conclusions: In our center, the frequency of femoral fracture was 11%, and it mainly affected severely injured young males due to traffic-related collisions or falls. Further multicenter studies are needed to set a consensus for an appropriate management of femur fracture based on the MOI, location, and timing of injury.

Abstract
INTRODUCTION The present study was done to assess the functional outcome and complications of interlocking intramedullary (IM) radius ulna nailing to treat radio-ulna fractures in adults. METHODOLOGY Thirty adult patients with diaphyseal or segmental fractures of radius and ulna were included and treated with IM nailing. Grace and Eversmann rating system was used to assess functional evaluation and grip strength was measured using grasp dynamometer. RESULTS Mean age of the 30 eligible patients was 33.5 years, and males comprised 77% of the study population. Intra-operative complications like nail impaction and proximal screw locking problem for radius was present in one patient each. Increased swelling in three patients (10%) and posterior interosseous nerve palsy in one patient (3%) were observed post-operatively. In the post-operative period, all patients were able to move fingers, had 100° elbow range of motion and good grip strength. Pronation and supination till 80° was present in 80% and 57% of the patients respectively. Wrist flexion and dorsiflexion till 90° was present in 80% and 57% of the patients. Fracture union was confirmed radiologically in all cases at a mean of 3.6 weeks. Functional outcome was excellent in 73% and good in 13%. Grip strength was judged to be excellent in all cases. CONCLUSIONS Excellent and good functional outcomes were obtained in 86%, and no case developed mal-union or delayed union. Based on our results, IM nail for surgical treatment of radial and ulnar diaphyseal fractures can be used.

Abstract
Background and aim of the work: to review and discuss the literature about rotational malalignment during and after femoral nailing. Methods: analysis of the literature on prevention and evaluation of rotation during femoral nailing, clinical and subjective consequences of malrotation and techniques used to correct the deformity, both in the acute and chronic phase. Results: malrotation is very common after femoral nailing. The exact definition of a malrotated femur is controversial, but it is widely agreed that a rotational malalignment <10° is considered normal while >30° is a deformity which requires correction. The complaints of the patients with a malrotated femur can be various and can involve the hip, the knee or below the knee. The ability to compensate for the deformity while standing and walking may decrease the symptoms. Surgical correction is feasible with many techniques and devices: the procedure involving derotation, changing the locking screws and maintaining the nail is safe, reproducible and relatively easy. Conclusions: prevention of malrotation during femoral nailing is the cornerstone of successful operation outcomes. If rotational malalignment is suspected, prompt diagnosis and adequate surgical treatment are mandatory to overcome this common complication. (www.actabiomedica.it)

Does Open Reduction in Intramedullary Nailing of Femur Shaft Fractures Adversely Affect the Outcome? A Retrospective Study. Adv Orthop 2020; 2020:7583204. [PMID: 32547791 PMCID: PMC7273415 DOI: 10.1155/2020/7583204] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Revised: 02/13/2020] [Accepted: 02/28/2020] [Indexed: 11/17/2022] Open
Abstract
Aim This study aims to assess the results of open versus closed reduction in intramedullary nailing for femoral fractures and whether it delays union, predisposes to nonunion, or increases the rate of infection. Materials and Methods A retrospective review of all adult patients with isolated femoral shaft fractures treated by intramedullary nailing was done. The primary outcome is union rate, and the secondary outcomes are operation time and the infection rate. Results 110 isolated femoral shaft fractures, with 73 (66.4%) in the closed reduction group and 37 (33.6%) in the open reduction group, 90.4% males and 9.6% females, and the average age was 32.6 years. RTA is the most common cause of these injuries followed by the fall from height. The delayed union rate was 20% (22/110) with no difference between the two groups, p value 0.480, and the nonunion rate was 5.5% (6/110), and no statistical difference was observed between the two groups. The operation time was shorter in the closed groups, and no difference in the time to union was observed between two groups. No infection was found in the two groups. Conclusions There is no statistical difference between the healing rates in closed and open reduction in femoral shaft fractures. In cases where closed reduction is difficult, it is better to open reduce the fracture if closed reduction cannot be achieved in 15 minutes, especially in polytrauma.

Abstract
Femoral shaft fractures present high morbidity and important complications and consequences, being spiral fractures the most complicated from a biomechanical point of view, being unstable and without possibility of getting a good contact between nail and femoral endosteum. Femoral diaphyseal fractures are treated, usually, by means of intramedullary nailing. So, it is necessary to know the osteosynthesis stability and which locking screws combination is optimal. This work studies the use of reamed locked intramedullary nails in spiral femoral fractures located along zones 2 and 4 of wiss, depending on the spire length, corresponding to 32-A spiral type in AO/OTA classification, which represent a percentage of 23% within the total of diaphyseal fractures. A three-dimensional finite element model of the femur was developed, modeling a spiral fracture with different spiral lengths and gaps. A femoral nail was used, considering two transversal screws both at the proximal and the distal parts. The study was focused on the immediately post-operative stage, verifying the appropriate stability of the osteosynthesis. Reamed intramedullary blocked nails provide appropriate stability of femoral spiral fractures, considering global mobility of femoral head with respect to femoral condyles, relative displacements between fragments at fracture site, stresses at nail and locking screws, and stresses at cortical bone. The obtained results show that the use of blocked reamed nails in spiral femoral fractures can be considered as an appropriate surgical technique, providing sufficient stability in order to obtain an adequate fracture healing.

Study protocol: design and rationale for an exploratory phase II randomized controlled trial to determine optimal vitamin D 3 supplementation strategies for acute fracture healing. Pilot Feasibility Stud 2019; 5:135. [PMID: 31768262 PMCID: PMC6873563 DOI: 10.1186/s40814-019-0524-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2018] [Accepted: 10/23/2019] [Indexed: 12/20/2022] Open
Abstract
Background Observational studies have found that 75% of healthy adult fracture patients (ages 18-50) have serum 25-hydroxyvitamin D (25(OH)D) levels < 30 ng/mL. Although lower serum 25(OH)D levels have yet to be correlated to fracture healing complications or poor fracture outcomes, many orthopedic surgeons are routinely prescribing vitamin D supplements to improve fracture healing in healthy non-osteoporotic patients. To address this gap in the literature, we propose a phase II exploratory randomized controlled trial comparing three vitamin D3 dosing regimens for early surrogate treatment response. Methods We will conduct a 4-arm blinded exploratory phase II trial in 96 adults aged 18-50 years with a closed or low-grade open (Gustilo type I or II) tibial or femoral shaft fracture. Eligible patients will be randomized in equal allocation ratio of 1:1:1:1 to one of the treatment groups: (1) 150,000 IU loading dose vitamin D3 plus daily dose placebo; (2) loading dose placebo plus 4000 IU vitamin D3 per day, (3) loading dose placebo plus 600 IU vitamin D3 per day, or (4) loading dose placebo plus daily dose placebo. The primary outcome is fracture healing, assessed as follows: (1) clinical fracture healing measured using the Function IndeX for Trauma, (2) radiographic fracture healing measured using the Radiographic Union Score for Tibial fractures, and (3) biological fracture healing measured using serum levels of cross-linked C-terminal telopeptides of type I collagen and amino-terminal procollagen propeptides of collagen type I. The main secondary outcome will be assessed by measuring serum 25(OH)D levels. All outcome analyses will be exploratory and adhere to the intention-to-treat principle. Per-protocol sensitivity analyses will also be conducted. Discussion Study results will be disseminated through a publication in an academic journal and presentations at orthopedic conferences. Study results will inform dose selection for a large definitive randomized controlled trial and provide preliminary clinical data on which dose may improve acute fracture healing outcomes in healthy adult patients (18-50 years) at 3 months. Trial registration Vita-Shock (A Blinded Exploratory Randomized Controlled Trial to Determine Optimal Vitamin D3 Supplementation Strategies for Acute Fracture Healing) was registered at ClinicalTrials.gov (identifier NCT02786498) prior to enrollment of participants.

Abstract
Proximal femur fracture fixation with intramedullary nailing relies on stability at the fracture site and integrity of the fixation construct to achieve union. The biomechanics that dictate fracture site stability and implant stress depend on fracture type as well as implant features such as nail length, nail diameter, presence of distal fixation screws, and material composition of the implant. When deciding how to fix a fracture, surgeons have choices in these implant-related design variables. This study models all combinations of a range of implant variables for nine standard AO/OTA proximal femur fractures using finite element analysis. Under simulated maximum load during gait, the maximum stress in the implant and screws as well as interfragmentary motions at the fracture site in the axial and shear directions were computed. The results were separated by fracture type to show the influence of each design variable on measured biomechanical outcomes. Filling the reamed canal with the largest fitting nail diameter reduced axial and shear interfragmentary motion for all fracture types. Nail length was less predictive of shear interfragmentary motion for most simulated fracture types than other construct variables. Furthermore, gapping at the fracture site predisposed the construct to higher implant stresses and larger interfragmentary motions. Clinical significance: Biomechanical outcomes from this computational study can aid in surgical decision-making for optimizing hip fracture fixation with IM nailing. © 2019 Orthopaedic Research Society.

Abstract
Aim This study aimed at comparing the mechanical properties of conventional and locking dual plates in adjacent and orthogonal orientations for the surgical fixation of transverse femoral shaft fractures. It also assessed the failure mechanics after dual adjacent and orthogonal locking plate removal. Methods Thirty-two composite femurs were transversally osteotomized and randomly assigned for fixation with either dual locking or compression plates in an adjacent or orthogonal configuration. Sixteen specimens were preloaded axially to 20 N and single-leg stance loads were simulated. The remaining sixteen constructs were subjected to torsional loads of 10 Nm at a rate of 10 Nm/s in external and internal rotation of the femoral head in relation to the knee. Overall combined rotational stiffness was calculated. Eight different specimens with no osteotomy underwent the same experiments after dual locked plate removal and were tested to failure in combined eccentric axial and torsional modes. Data were statistically processed using a two-tailed t-test and one-way analysis of variance for the comparison of means between two or more groups, respectively. Results Orthogonal constructs were statistically stiffer in axial loading compared to their adjacent counterparts in both conventional and locking configurations (p<0.001). Dual locking plates provided higher torsional stiffness than conventional ones within each plate orientation (p<0.01). Neither axial/torsional strength nor failure loads differed between constructs that had adjacent or orthogonal dual locking plates instrumented and then removed (p>0.05). Conclusions In both orthogonal and adjacent orientations, double locking plates provide higher stability than their dual conventional counterparts. Orthogonal dual plate configuration is more stable and biomechanically superior to dual adjacent plating for constructs fixed with either standard compression or locking plates.

Abstract
Reaming is an important step in long bone nailing and has a low complication rate. We report a case of a flexible reamer that got broken and incarcerated in the femoral canal during reaming in a segmental femur fracture. Routine extraction using guide wire was not possible. The incarcerated reamer was successfully extracted with the help of a jumbo cutter.

Abstract
BACKGROUND and purpose: We have undertaken a systematic review to evaluate the clinical results of intramedullary nailing (IMN) for open diaphyseal femoral fractures on the rates of union, delayed union, malunion, superficial and deep infection and bone grafting. METHODS We searched the electronic databases of EMBASE, MEDLINE, from their inception until December 1st, 2017 with no language restrictions. The reference lists of all included articles and relevant reviews were also examined for potentially eligible studies. Hand search using electronic database of recent major orthopaedic journals was also carried. Two reviewers working independently extracted study characteristics and data to estimate the diagnostic odds ratio and 95% confidence interval for each result. RESULTS Seventeen studies were eligible. Pooled estimate of effect size for union rate was 97% (95% CI: 94-99%). Deep infection rate was 6% (95% CI: 3-9.3%) and more prominent in Gustilo type III injuries; superficial infection was 5.6% (95% CI: 3-9.3%). Delayed union rate 3% (95% CI: 1-5.6%) while, malunion rate was 8.4% (95% CI: 5.7-11.6%). The need for bone grafting ranged from 0 to 9%. CONCLUSIONS IMN remains the treatment of choice for open femoral diaphyseal fractures with very good union rates. Gustilo grade III injuries demonstrate a distinct higher deep infection rate and strict adherence to established surgical debridement and fixation protocols is advocated. The need for bone grafting can be as high as 9% and patients should be made aware of the possibility of requiring this additional procedure.

Abstract
INTRODUCTION There is no consensus yet on the impact of timing of femur fracture (FF) internal fixation on the patient outcomes. This meta-analysis was conducted to evaluate the contemporary data in patients with traumatic FF undergoing intramedullary nail fixation (IMN). METHODS English language literature was searched with publication limits set from 1994 to 2016 using PubMed, Scopus, MEDLINE (OVID), EMBASE (OVID), Web of Science, and Cochrane Central Register of Controlled Trials (CENTRAL). Studies included randomized controlled trials (RCTs), prospective observational or retrospective cohort studies, and case-control studies comparing early versus late femoral shaft fractures IMN fixation. Variable times were used across studies to distinguish between early and late IMN, but 24 h was the most frequently used cutoff. The quality assessment of the reviewed studies was performed with two instruments. Observational studies were assessed with the Newcastle-Ottawa Quality Assessment Scale. RCTs were assessed with the Cochrane Risk of Bias Tool. RESULTS We have searched 1151 references. Screening of titles and abstracts eliminated 1098 references. We retrieved 53 articles for full-text screening, 15 of which met study eligibility criteria. CONCLUSIONS This meta-analysis addresses the utility of IMN in patients with FF based on the current evidence; however, the modality and timing to intervene remain controversial. While we find large pooled effects in favor of early IMN, for reasons discussed, we have little confidence in the effect estimate. Moreover, the available data do not fill all the gaps in this regard; therefore, a tailored algorithm for management of FF would be of value especially in polytrauma patients.

Abstract
PURPOSE Nonunion is a highly morbid complication that exacerbates the pain, disability and financial burden of distal and diaphyseal femur fractures. This study examined the modern rates of healing, nonunion, and other complications requiring reoperation of different fixation methods for distal and diaphyseal femur fractures. METHODS A systematic review and meta-analysis of all records from PubMed, Embase and the Cochrane Review system was performed. Included studies had >20 acute, non-pathologic distal or diaphyseal femur fractures treated with primary internal fixation. Excluded were studies on abnormal patient/fracture populations, external fixation, or cement/bone graft use. RESULTS Thirty-eight studies with 2,829 femoral shaft fractures and 11 studies with 505 distal femur fractures were included. Distal fractures had a lower healing rate (86.6% vs. 93.7%) and a higher re-operation rate (13.4% vs 6.1%) than shaft fractures (p < 0.00001), primarily due to higher rates of mechanical failure (p < 0.00001). Nonunion was the most frequent complication, occurring in 4.7% of distal fractures and 2.8% of shaft fractures. There was no difference between plate and nail fixation of distal fractures in healing, nonunion, or other causes of re-operation. Shaft fractures developed nonunion in 6.6% of unreamed nails and 2.1% of reamed nails (p = 0.002). Nonunion occurred in 2.3% of antegrade nailed fractures and 1.5% of retrograde nailed fractures (p = 0.66). CONCLUSIONS Approximately one out of every eight distal fractures and one of every 16 shaft fractures requires re-operation. The most common cause of fixation failure is nonunion. Further research is needed to improve outcomes, particularly in distal femur fractures.

Abstract
Bone healing, biocompatibility, and safety employing the IlluminOss System (IS), comprised of an inflatable balloon filled with photopolymerizable liquid monomer, was evaluated in New Zealand white rabbits. Successful bone healing and callus remodeling over 6 months was demonstrated radiologically and histologically with IS implants in fenestrated femoral cortices. Biocompatibility was demonstrated with IS implants in brushed, flushed femoral intramedullary spaces, eliciting no adverse, local, or systemic responses and with similar biocompatibility to K-wires in contralateral femurs up to 1 year post-implant. Lastly simulated clinical failures demonstrated the safety of IS implants up to 1 year in the presence of liquid or polymerized polymer within the intramedullary space. Polymerized material displayed cortical bone and vasculature effects comparable to mechanical disruption of the endosteum. In the clinically unlikely scenario with no remediation or polymerization, a high dose monomer injection resulted in marked necrosis of cortical bone, as well as associated vasculature, endosteum, and bone marrow. Overall, when polymerized and hardened within bone intramedullary spaces, this light curable monomer system may provide a safe and effective method for fracture stabilization. © 2017 Orthopaedic Research Society.

Abstract
The extraction of broken femoral nails can be a challenging procedure and surgeons should be familiar with many different techniques. This paper demonstrates a case study and new, simple and cost effective technique for the removal of broken cannulated femoral nails. Our technique uses two guide wires of variable diameter and had several key points of differentiation from previous methods. Firstly, stuffing the nail with guide wires of greater total diameter than the cannula; secondly, reversing the second guide wire and finally, bending the tips of the wires. These innovations allow the technique to be used for narrow cannulated nails, superior purchase along the length of the nail, easy wire insertion and limited soft tissue damage. Our technique for the removal of broken femoral nails is quick, effective, cheap and easy to replicate and can be used by any generalist orthopaedic surgeon with basic equipment.

Abstract
OBJECTIVES The purpose of this study was to evaluate posterior malleolar injuries associated with nailed tibial fractures and to determine the quality of reduction based on the sequence of fixation in associated fracture patterns. DESIGN Retrospective cohort study. PATIENTS 1113 tibia fractures treated with an intramedullary nail at 3 level I trauma centers. INTERVENTION Tibial shaft fractures with posterior malleolar injury were analyzed regarding type of fracture, mechanism of injury, energy of injury, fracture characteristic, surgical characteristics including sequence of fixation, obvious intraoperative displacement of the posterior malleolar fragment, and the quality of reduction. One group ("malleolus-first") consisted of patients in whom the posterior malleolus was fixed before tibial nailing and the other group ("tibia-first") included patients in whom tibial nailing was done before posterior malleolus fixation. OUTCOMES MEASURED Intraoperative displacement, quality of reduction. RESULTS Ninety-six of 1113 (9%) nailed tibial shaft fracture patients had a concomitant posterior malleolus fracture (9%). Of the 96 posterior malleolar fracture patients, 70 patients were operatively treated (73%). In the malleolus-first group (54 patients), intraoperative displacement of the posterior malleolar fragment was observed in 1 patient, and 1 case of poor reduction of the posterior malleolar fragment was observed (2%). In the tibia-first group (16 patients), obvious intraoperative displacement of the posterior malleolar fragment was observed in 5 patients (31%), and poor reduction of the posterior malleolar fragment was observed in 7 patients (44%). These percentages of patients with poor quality of reduction were statistically significantly different (p ≤ 0.01). CONCLUSION Many low-energy tibia fractures with a spiral configuration do have an associated posterior malleolus fracture. In order to avoid intraoperative displacement and poor reduction, we recommend fixation of the posterior malleolar fragment before nailing of the tibia in associated fracture pattern.

Abstract
PURPOSE Early intramedullary nailing (IMN) within the first 24 h for multiply injured patients with femoral fracture and concomitant thoracic trauma is controversial. Previously published studies have been limited in size and their outcomes have been inconclusive. A meta-analysis was conducted to evaluate the available data in order to guide care and help improve the outcomes for these patients. METHODS We searched the literature up to December 2011 in the main medical search engines and identified 6 retrospective cohort studies that explored the safety of early IMN in patients with both femoral fracture and chest injury. Our primary outcome was the rates of pulmonary complication (pneumonia, adult respiratory distress syndrome, fat embolism syndrome), multiple organ failure (MOF) and mortality. RESULTS We found no statistically significant difference in the rate of pulmonary complications, MOF or mortality in the patients treated with early IMN. CONCLUSION Early IMN for femoral fractures does not increase the mortality and morbidity in chest- injured patients in the studies analyzed.

Abstract
Percutaneous intramedullary fixation may provide an ideal method for stabilization of bone fractures, while avoiding the need for large tissue dissections. Tibiae in 18 sheep were treated with an intramedullary photodynamic bone stabilization system (PBSS) that comprised a polyethylene terephthalate (Dacron) balloon filled with a monomer, cured with visible light in situ, and then harvested at 30, 90, or 180 days. In additional 40 sheep, a midshaft tibial osteotomy was performed and stabilized with external fixators or external fixators combined with the PBSS and evaluated at 8, 12, and 26 weeks. Healing and biocompatibility were evaluated by radiographic analysis, micro-computed tomography, and histopathology. In nonfractured sheep tibiae, PBSS implants conformably filled the medullary canal, while active cortical bone remodeling and apposition of new periosteal and/or endosteal bone was observed with no significant macroscopic or microscopic observations. Fractured sheep tibiae exhibited increased bone formation inside the osteotomy gap, with no significant difference when fixation was augmented by PBSS implants. Periosteal callus size gradually decreased over time and was similar in both treatment groups. No inhibition of endosteal bone remodeling or vascularization was observed with PBSS implants. Intramedullary application of a light-curable PBSS is a biocompatible, feasible method for fracture fixation.

Abstract
Background: Femoral shaft fractures are among the most common fractures following high trauma injuries. Different kinds of treatment have been suggested for these injuries. Aim: The aim of this study was to compare the results femoral fractures treated by mini open and close intramedullary nailing (IMN) technique. Materials and Methods: A total of 48 adult patients were operated due to fracture of the femur with close or open IMN technique between September 2010 and September 2011. 23 patients operated with close. IMN technique was included in Group I while 24 patients operated with mini open IMN technique constituted Group II. In Group I, all patients. Were operated on the fracture table in the supine position while in Group II, all patients underwent surgery on standard tables in the lateral position. Results: The mean age of patients was 27.3 years, ranging between 16 and 62. The mean age of the close nailing and open nailing groups was 30.5 and 24.5 respectively (P = 0.052). Only one patient from the open nailing group failed to unite. The mean time for union in close and open nailing groups was 13 + 2.4 and 17.7 + 2.3 weeks respectively (P = 0.001). No infection or limb length discrepancies were observed in the two groups. Conclusion: Although close nailing is the preferred methods in most cases, but in poly-traumatized patients or in centers where there are no fracture tables or C-arm, open nailing is a good option.

Abstract
INTRODUCTION Fracture of the femoral shaft is a common fracture encountered in orthopedic practice. In the 1939, Küntscher introduced the concept of intramedullary nailing for stabilization of long bone fractures. Intramedullary nailing has revolutionized the treatment of fractures. MATERIAL AND METHODS The study included 37 male patients and 13 female patients, averaged 39 +/- 20.5 years (range, 16 to 76 years). RESULTS AND DISCUSSION There were 31 left femurs and 21 right femurs fractured. 46 fractures were the result of blunt trauma. Low energy trauma was the cause of fractures in six patients, of which five in elderly females. 49 fractures were closed. Healing time given in weeks was 19.36 +/- 6.1. The overall healing rate was 93.6%. There were three (6.25%) major complications nonunion. There were one (2%) delayed union, one (2%) rotational malunion and no infection. The shortening of 1 cm were in two patients. Antercurvatum of 10 degrees was found in one patient. There was no statistically significant reduction of a motion in the hip and knee (p < 0.05). There was statistically significant in the thigh (knee extensors) muscle weakness (p < 0.001). CONCLUSION : Intramedullary nailing is the treatment of choice for femoral shaft fractures.

Abstract
INTRODUCTION The treatment goal for diaphyseal forearm fractures in adults is to restore axial and rotational stability. The treatment of these fractures with intrmaedullary locked nailing remains sparse. We therefore evaluated IM nails for treating forearm diaphyseal fractures in adults. METHODS We retrospectively reviewed adult patients with isolated unilateral or bilateral fractures of the radius, ulna, or both, who were treated with closed or mini open reduction with a new IM nail between May 2008 and January 2012 and who were followed for a least 1 year. Patients with a Galeazzi fracture, a pathological fracture or patients with nonunion after previous surgeries were excluded. All patients were allowed full range of motion without any external support. Primary outcomes were Grace and Eversmann rating, Disabilities of the Arm, Shoulder and Hand (DASH) scores. RESULTS The 43 enrolled patients (mean age, 37 years; 32 men) had 59 forearm fractures: 14 isolated radius fractures, 17 isolated ulna fractures (2 bilateral), and 28 fractures of both the radius and ulna. Mean time to fracture union was 13 weeks (range 10-14 weeks) for ulnar fractures and 12 weeks (range 10-13 weeks) for radial fractures. No patient had nonunion, deep infections, or radioulnar synostosis. Followup ranged from 12 to 44 months. Grace and Eversmann ratings were excellent in 38 patients and good in 5. Mean DASH score was 6.5 points (range 0-13.3). CONCLUSIONS Intramedullary nailing of adult forearm diaphyseal fractures appears to be a good alternative to plate osteosynthesis. The advantages are short operative time, minimal invasive techniques, and sufficient stability in all planes that allows early motion without additional fracture support.

Abstract
OBJECTIVE This study aims to evaluate the results of intramedullary nail treatment in surgical treatment of adult displaced radius and ulna diaphyseal fractures. PATIENTS AND METHODS Eighteen patients (36 forearm fractures) who underwent intramedullary nail treatment due to radius and ulna fractures were retrospectively analyzed. Adult patients with displaced forearm double fractures were included in this study. Patients with open physeal lines, pathological fractures, Monteggia and Galeazzi fractures, distal radioulnar joint instability, bilateral fractures and bone loss were excluded. RESULTS Thirteen patients were male (72.2 %) and five were female (27.8 %). Average age of the patients was 35.16 (18-63). Twelve patients (66.7 %) suffered right and six patients (33.3 %) left forearm fractures. Average follow-up period was 77.7 (55-162) weeks, average bleeding amount was 51.11 (15-100) ml, average time to bone union was 11.3 (8-20) weeks, average surgery time was 61.94 (45-80) min and average fluoroscopy time was approximately 2 (1-5) min. According to Grace-Eversman criteria, results were excellent in 14 (77.8 %) patients, good in 3 (16.8 %) and acceptable in 1 (5.6 %). Average DASH questionnaire score was 15.15 (4-38.8). There was no iatrogenic vascular, neural and bone injury during surgery. There was late rupture of extensor pollicis longus tendon in one patient, 4 months after surgery. CONCLUSION Intramedullary fixation method has advantages, such as closed application, short surgery period, good cosmetic results and early return to movement. We think intramedullary fixation method may be used as an alternative treatment method to plate osteosynthesis in surgical treatment of radius and ulna diaphyseal fractures.

Abstract
BACKGROUND The goal of the radius diaphysis fractures in surgical treatment is restoration of bone length, rotation correction and to secure fixation that allows early mobilization. The purpose of this study is evaluating the results of intramedullary (IM) radius nail for the treatment of isolated adult diaphyseal fractures of the radius. MATERIALS AND METHODS We retrospectively reviewed adults with isolated fractures of the radius, who were treated with closed or mini open reduction with a IM radius nail between May 2008 and November 2011 and who were followed for a least 1 year. Patients with a Galeazzi fracture, a pathological fracture, or patients with nonunion after previous surgeries were excluded. All patients were allowed full range of motion without any external support. Primary outcomes were Grace and Eversmann rating, Disabilities of the Arm, Shoulder and Hand (DASH) scores. RESULTS Twenty-three enrolled patients (mean age 34 years; 17 men) had 23 isolated radius fractures. Mean time to fracture union was 12 weeks (range 10-13 weeks) for radius fractures. No patient had nonunion, deep infections, or radioulnar synostosis. Follow-up ranged from 12 to 42 months. Grace and Eversmann ratings of 21 patients were excellent or good, and 2 patients were medium. Mean DASH score was 4.2 points (range 0-13.3). CONCLUSIONS Our experience indicates that this new IM radius nail may be considered as an alternative to plate osteosynthesis for fractures of the radius diaphysis in adults. IM nailing of radius fractures provides reliable bony union and excellent postoperative clinical results in adults.

Abstract
Intramedullary nailing is considered the standard of care for closed femoral shaft fractures. Several studies have shown that reamed intramedullary nailing is a safe procedure in fracture shaft femur with lower nonunion rates than unreamed nailing. Reamed intramedullary nailing provides better stability because of increased contact between the nail and medullary canal. However, careful attention to reaming techniques as well good instrumentation is necessary while undertaking such a procedure. We report what is, to the best of our knowledge, the first case of uncoiling of reamer while reaming the medullary canal. Possible causes and measures to avoid such a complication are discussed.

Abstract
OBJECTIVES To examine the association of reamed intramedullary nailing (IMN) and long-term cognitive impairment in trauma intensive care unit survivors. DESIGN Prospective observational cohort. SETTING Academic Level I trauma center. PATIENTS One hundred seventy-three patients with multiple trauma (Injury Severity Score greater than 15) who presented to a Level I trauma intensive care unit from July 2006 to July 2007 without evidence of intrancranial hemorrhage. INTERVENTION None. MAIN OUTCOME MEASURE Twelve-month cognitive impairment defined a priori as two neuropsychological test scores 1.5 standard deviation below the mean or 1 neuropsychologic test score 2 standard deviations below the mean. RESULTS One hundred eight of 173 patients (62.4%) were evaluated 12 months after injury with a comprehensive battery of neuropsychological tests. There were 18 patients who received a reamed IMN and 14 of 18 (78%) of these patients had cognitive deficit at follow-up. Fracture treatment with a reamed IMN was associated with long-term impairment (27.4% vs 8.2%, P = 0.03). Multivariable logistic regression found that a reamed IMN (odds ratio, 3.2; 95% confidence interval, 0.95-10.9; P = 0.06) was a moderate risk factor for the development of cognitive impairment 12 months after injury after controlling for Injury Severity Score, level of education, intraoperative hypotension, and duration of mechanical ventilation. CONCLUSIONS Fracture fixation with a reamed IMN is moderately associated with cognitive impairment in this cohort of multiple trauma patients without intrancranial hemorrhage at 1 year postinjury. Orthopaedic trauma research should continue to investigate a potential association of acute fracture management and long-term cognitive outcome.

Abstract
In this work, a testing protocol has been set up, in order to quantify the load-sharing imposed near the fracture site by an interlocking-type intramedullary nail. A simulated single-leg stance has been applied to a composite fiberglass femur in three different configurations simulating: an intact femur, a fractured nailed femur and a fully healed nailed femur. The repeatability of the measurements and the influence of ilio-tibial band muscle force have been investigated. The tested nail proved to share with the femoral shaft an amount of the total applied load ranging from 50% immediately after the nailing to 80% at full healing.

Abstract
BACKGROUND The long-term functional implications for patients with iatrogenic femoral malrotation following femoral intramedullary nail fixation remain unclear. This study examined the extent and direction of rotational alignment of the femur treated with intramedullary nail fixation and its long-term functional effects on patients' standing, walking, and subjective outcome. METHODS Rotational alignment was measured using a CT-based protocol. Foot alignment while standing or walking was determined bilaterally using a pressure mat. Subjective functional outcome was assessed using a questionnaire. FINDINGS Sixteen patients (5F, 11 M; age: mean 44.3 years, range 24-75 years) with a healed femur fracture were included. Femur alignment demonstrated internal rotation in five patients (mean 6°; range 2-13°), and external rotation in 11 (mean 18°; range 3-32°). Static foot rotation demonstrated neutral rotation in two patients, internal rotation in four (mean 13°; range 5-22°), and external rotation in 10 (mean 15°; range 5-24°). Dynamic foot rotation demonstrated neutral rotation in two patients, internal rotation in two (mean 11°; range 4-26°), and external rotation in 12 (mean 11°; range 3-22°). There was a trend for increasing dynamic malrotation with femoral rotation (r(2)=0.27; p=0.055). In half the patients, dynamic foot rotation correlated with the extent of femoral malrotation. There was no association (p=0.6) between overall patient satisfaction (10 fully satisfied; 5 partially satisfied; and 1 dissatisfied) and foot alignment. INTERPRETATION Patients can compensate for even significant femoral malrotation and tolerate it well. External femoral malrotation appears to be better compensated/tolerated than internal malrotation.

Abstract
OBJECTIVE To compare the intramedullary pressures developed during reaming of cadaveric femurs with the Synthes Reamer/Irrigator/Aspirator (RIA) reamer and the Zimmer Pressure Sentinel (PS) reamer, controlling for the force and speed of reaming. METHOD Fifteen matched pairs of frozen unpreserved femurs were used in the study. Two pressure transducers and two thermocouples were screwed into holes drilled into the femoral shaft. The femurs were stabilized in the vertical position by mechanically attaching them to a custom jig equipped with a load cell to detect the vertical component of force applied to the reamer. Proximally a linear voltage displacement transducer (LVDT) was attached to the reamer to record the continuous position of the reamer. All femurs were reamed to a diameter 2 mm larger than the narrowest point of the canal. Proximal and distal pressures, proximal and distal temperatures, applied vertical force and displacement were measured continuously throughout the reaming process. Maximum and minimum, and average proximal and distal pressures for each reamer were obtained and compared using paired t-tests. Averages were also calculated and compared in the same manner. A p-value of <0.05 was considered statistically significant. RESULTS The maximum, minimum and average intramedullary pressures during reaming were significantly lower with the RIA system than the PS reamer. In general, the pressures produced by the RIA system were consistently below atmospheric pressure for the majority of the reaming time. This was not true for the PS system. No appreciable temperature changes were observed during any of the trials. CONCLUSION The RIA reaming system significantly reduces the intramedullary pressures produced during the reaming process compared to the PS reaming system.

Abstract
Head injuries are present in up to 65 % of multiple trauma patients with a frequent association with orthopaedic injuries. The concept of early surgical stabilization of long-bone fractures in patients with multiple injuries became firmly established in the 1980s. However, optimal timing of long bone fracture fixation in trauma patients with associated severe traumatic brain injury has been a lively topic. The available literature does not provide clear-cut guidance on the management of fractures in the presence of head injuries. The trend is toward a better outcome if the fractures are fixed early. In recent years, some studies reported a worse outcome, with secondary brain damage, resulting from hypotension, hypoxia and increased intraoperative fluid administration. This review summarises the current evidence available regarding the management of these patients in particular the recent concept of early temporary surgical stabilization in the era of "damage control orthopaedic surgery".

Abstract
PURPOSE To review the treatment outcome of patients with neglected femoral shaft fractures. METHODS Records of 22 men and 3 women aged 20 to 55 (mean, 36) years who underwent open interlocking nailing and bone grafting for neglected (2-month-old or more) closed femoral shaft fractures were reviewed. 21 had nonunion and 4 had malunion. All patients had deformed, shortened, and wasted lower limbs, with knee stiffness. The mean delay in presentation was 3 (range, 2-7) months. RESULTS Patients were followed up for a mean of 18 (range, 14-30) months. The mean time for radiological union was 5 (range, 4-7) months. Three patients had delayed union (6 months or more) and underwent secondary procedures (dynamisation or bone marrow injection). None had non-union. All had some degree of shortening; in 3 it was >2 cm. None had neurological injury following acute gain in length. None had deep infections; 2 had superficial wound infections and 6 had pin tract infections. Mean knee flexion improved 50 (from 70 to 120) degrees and the mean extensor lag decreased 7 (from 15 to 8) degrees. After a mean of 18 weeks, 23 of the patients were able to return to their work. CONCLUSION Open interlocking nailing and bone grafting coupled with aggressive rehabilitation can achieve acceptable results for patients with neglected femoral shaft fractures.

Abstract
Radiographic assessment of tibial fracture healing continues to pose significant challenges to both routine fracture care and clinical research. Orthopaedic surgeons fail to achieve sufficient agreement on fracture healing when using conventional radiographic measures such as their general impression or the number of cortices bridged by callus. Moreover, the extent to which radiographic assessment of healing corresponds to patient-important outcomes is largely unknown. In an attempt to improve the former (ie, reliability) and inform the latter (ie, validity), recent studies have explored a novel radiographic assessment for tibial shaft fractures, the Radiographic Union Scale for Tibial fractures (RUST). The RUST score assesses the presence of bridging callus and that of a fracture line on each of 4 cortices seen on 2 orthogonal radiographic views. A recent study has found that RUST scores have greater inter-rater reliability when compared with surgeon's general impression or the number of cortices bridged by callus. This may increase the utility of radiographs as a standardized measure of treatment efficacy in the follow-up of tibial fractures.

Intramedullary nailing of proximal tibia fractures--an anatomical study comparing three lateral starting points for nail insertion. Injury 2010; 41:220-5.

Abstract
INTRODUCTION Intramedullary nailing is challenging in proximal tibia fractures, associated with high rates of malalignment. To date, no studies report the potential of lateral tibia nail insertion to correct primary valgus malalignment, commonly seen in proximal quarter fractures. MATERIALS AND METHODS 18 fresh-frozen cadaver lower extremities were used to simulate an AO/OTA 41-A3 fracture. Six nails (Expert Tibial Nailing System, Synthes, Salzburg, Austria) were inserted at the lateral third, six nails at the middle third and six nails at the medial third of the lateral tibia plateau. After nail insertion, alignment in the coronal plane was recorded. RESULTS Mean varus malalignment was dependent on the entry point at the lateral tibia plateau. Mean varus malalignment was 16 degrees if nails were inserted at the lateral third, 10 degrees at the middle third and 4 degrees after nail insertion at the medial third. If nails were inserted from the medial third, valgus malalignment was recorded in two specimens. DISCUSSION The effect of correction of coronal malalignment in proximal tibia fractures is dependent on the point of nail entry at the lateral plateau. Primary valgus deformation up to 20 degrees can be corrected by inserting tibia nails at the lateral third of the lateral tibia plateau. Surgeons should be aware of possible varus deformity and valgus malalignment despite lateral nail insertion.

Abstract
A technical benefit of the reamer-irrigator-aspirator (RIA) system (Synthes, Paoli, PA) is the ability to harvest large volumes (40-90 cm3) of autogenous bone graft. Early evaluations of this technique have reported few problems, all of which were attributed to technical error. This case series reviews 6 RIA-associated complications including 4 fractures and their contributing risk factors. Cases were collected from 4 independent orthopaedic centers, and all patients underwent RIA bone graft harvesting in a lower extremity long bone injuries. In this population, 2 patients experienced acute RIA-associated events, necessitating an additional procedure or altered postoperative rehabilitation, whereas 4 patients fractured through their donor site in the early postoperative period. This series suggests that surgeons should (1) preoperatively assess cortical diameters at long bone harvest sites, (2) carefully monitor intraoperative reaming, and (3) avoid RIA bone graft harvesting in patients with a history of osteoporosis or osteopenia unless postharvest intramedullary stabilization is considered.

Abstract
BACKGROUND Reamed intramedullary nailing is the current gold standard for the treatment of diaphyseal fractures of the femur and tibia. Current concepts of orthopedic damage control surgery for patients with multiple injuries have placed an emphasis on appropriate surgical timing, limiting blood loss, and the duration of the initial operative procedure(s). Proponents of unreamed nailing have stated that reaming places polytraumatized patients "at risk," in part because it adds to the length of the surgical procedure and may exacerbate the severity of a patient's pulmonary injury. The purpose of this study was to determine how many minutes reaming actually takes and what percentage of operative time reaming comprises during intramedullary nailing of femoral and tibial shaft fractures. METHODS Intraoperative timing data were collected prospectively on a total of 52 patients with 54 fractures (21 femoral and 33 tibial) who underwent reamed intramedullary nailing of acute closed or open femoral or tibial shaft fractures over a 10-month period. Total operating room, surgical, and reaming times were collected. RESULTS The average reaming time for femur and tibia fractures was 6.9 minutes and 7 minutes, respectively. On average, reaming accounted for 4.9% of the surgical time and 3.2% of the total operating room time for femur fractures and 4.9% of the surgical time and 3.4% of the total operating room for tibia fractures. CONCLUSION Our results show that reaming comprises a small percentage of the operative time and the total time a patient spends in the operating room.

Abstract
In order to evaluate the impact of simultaneous intramedullary nailing in patients with bilateral femoral fractures on systemic complications a comprehensive review of the literature was performed. Four studies reporting the results of 197 patients following trauma were analysed. The mean Injury Severity Score was 20.6 (range, 9-75). According to the data available, reamed intramedullary nailing was performed in 96% of the cases. The incidence of fat embolism was 4.1%, ARDS 14.6% and pulmonary embolism 6.9%. The overall mortality was 6%. The mean hospital stay was 17.9 days (range, 4-108). Bilateral femoral fractures have a high risk of complications and mortality. Damage control surgery should be considered in these cases where the clinician anticipates the development of systemic complications.

Abstract
Intramedullary nailing is the preferred method for treating fractures of the femoral shaft. The piriformis fossa and greater trochanter are viable starting points for antegrade nailing. Alternatively, retrograde nailing may be performed. Each option has relative advantages, disadvantages, and indications. Patient positioning can affect the relative ease of intramedullary nailing and the incidence of malalignment. The timing of femoral intramedullary nailing as well as the use of reaming must be tailored to each patient to avoid systemic complications. Associated comorbidities, the body habitus, and associated injuries should be considered when determining the starting point, optimal patient positioning for nailing, whether to use reduction aids as well as which to use, and any modifications of standard technique. Intramedullary nailing of diaphyseal femur fractures provides a stable fixation construct that can be applied using indirect reduction techniques. This method yields high union rates and low complication rates when vigilance is maintained during preoperative planning, the surgical procedure, and the postoperative period.

Abstract
Intramedullary fixation has advanced to the standard of care for fractures of the femoral shaft. Current controversies center on whether to prepare the intramedullary canal by reaming, particularly in certain subsets of patients. As understanding of the local and systemic effects of reaming deepens, there is a role for maximizing the benefits of intramedullary preparation before nail fixation, while attempting to minimize the major disadvantages of this technique. Several treatment strategies have emerged to address the downsides of intramedullary reaming. The purpose of this review is to discuss the history and current knowledge of intramedullary reaming with respect to problems associated with its use and the evolution of treatment modalities and their clinical applicability for orthopaedic trauma care.
