RESUMO
INTRODUCTION: Aim of our study was to evaluate the influence of working length and screw density on callus formation in distal tibial fractures fixed with a medial bridge plate. MATERIALS AND METHODS: 42 distal tibia fractures treated with a bridge plate were analyzed. Minimum follow-up was 12 months. mRUST score (modified Radiographic Union Scale for Tibial fractures) was used to assess callus formation. Working length and screw density were measured from post-operative radiographs. RESULTS: 39 (92.9%) fractures healed uneventfully. 32 (76.19%) patients showed signs of early callus formation 3 months post-surgery. In these patients a lower screw density was used compared to patients who didn't show early callus (33.4 vs. 26.6; p = 0.04). No differences was noticed in working length. CONCLUSION: Bridge plate osteosynthesis is a good treatment option in distal tibia fractures. In our series increasing the working length was not associated with a faster callus formation in distal tibia fractures. Conversely, a lower screw density proximally to the fracture site was associated to a faster callus growth.

INTRODUCTION: Open fractures of the distal tibia can be functionally devastating, and they remain one of the most challenging injuries treated by trauma surgeons usually burdened with a high rate of complications, including surgical site infections (SSI). Our aim is to analyze the most significant risk factors of SSI and propose a new scoring system-called the DANGER scale-potentially able to predict reliably and quantify the infection risk in distal tibia open fractures. METHODS: We identified six variables summarized in the acronym DANGER where D stands for Diabetes, A for Antibiotic, N for Nature of trauma (high- or low-energy trauma), G represents Grade of fracture following the AO/OTA classification, E indicates Exposure of the fracture according to the Gustilo-Anderson classification, and R represents Relative risk of patient, including use of tobacco, alcoholism, and psychiatric disorders. Therefore, total score ranged from 1 to 14, with a lower score indicating less risk to develop SSI. RESULTS: A total of 103 patients with open distal tibial fractures were enrolled, 12 patients (11.6%) developed SSI. Regarding DANGER score, a rating of 8.2 was calculated in SSI group and 4.8 in non-SSI group. Based on Fisher's test, diabetes (odds = 31.8 p < 0.05), grade of articular involvement (p < 0.05), severity of open fracture (p < 0.05), and dangerous behavior such as use of tobacco, alcoholism, and psychiatric disorders (p < 0.05) were significantly correlated with infection. Significant difference between total DANGER scores in SSI and non-SSI groups was found (p < 0.001). ROC curve was calculated founding a potential threshold of 7.5 (p < 0.001). CONCLUSION: Based on the above well-accepted risk factors, DANGER scale represents an advantageous and practical tool in order to readily estimate the risk of surgical site infection of open distal tibial fractures.

Radial head excision has always been a safe commonly used surgical procedure with a satisfactory clinical outcome for isolated comminuted radial head fractures. However, diagnosis of elbow instability is still very challenging and often underestimated in routine orthopaedic evaluation. We present the case of a 21-years old female treated with excision after radial head fracture, resulting in elbow instability. The patient underwent revision surgery after four weeks. We believe that ligament reconstruction without radial head substitution is a safe alternative choice for Mason III radial head fractures accompanied by complex ligament lesions.

PURPOSE: To describe our clinical experience with a system named SureShot? Distal Targeting (Smith & Nephew, Memphis, USA) based on magnetic field presence and discuss our suggestions on this technique. METHODS: We analysed prospectively 47 patients affected by humeral, tibial or femoral fractures, treated in our institution during a 3-year period of time (August 2010 to September 2013). We considered the following parameters: the time to set up, the time to position a single screw, the effectiveness of the system (drilling ad screwing), the irradiation exposure time during distal locking procedure and surgical complications. RESULTS: A total number of 96 screws were inserted. The mean preparation time of the device was 5.1 min ± 2 min (range 3-10 min). The mean time for single screw targeting was 5.8 min ± 2.3 min (range 4-18 min). No major complications occurred. Only a few locking procedures were needed to be practiced in order to obtain the required expertise with this targeting device. CONCLUSION: According to our results, this device is reliable and valid whenever the correct technique is followed. It is also user friendly, exposes to lower radiation and needs less surgical time compared to relative data from the literature. However, the surgeon should always be aware of how to use the free hand technique in case of malfunctioning of the system.

PURPOSE: The optimal surgical treatment of displaced type B and C fractures of the proximal humerus in the elderly remains controversial. Good clinical results have been reported by plating these fractures as well as a high rate of complications. Our retrospective study aims to evaluate clinical recovery and complications using the S3 locking plate in elderly patients. METHODS: Fifty-one patients older than 65 years of age, with a complex proximal humeral fracture type B or C (AO classification system), were included. Patients have been followed up for a minimum of 12 months. We assessed callus formation, radiological results, clinical outcome (according to the Constant Shoulder Score System) and complications. Any difference in the clinical recovery among the 2 types of fracture pattern (B and C) was investigated. RESULTS: The mean time of fracture healing was 12.4 weeks. The mean Constant score at 3, 6 and 12 months was 68, 73 and 75 respectively. No statistically significant difference in the clinical outcome was observed between the B and C fracture patterns (p > 0.05). We noticed an overall of 5 complications (9.8%). There was no need to revision any of the implants. CONCLUSION: Anatomic reduction and proper plate positioning are essential for minimizing implantrelated complications. In our experience the S3 angular stability system offers a proper osteosyntesis and a good clinical recovery with a low rate of complications.

OBJECTIVE: The anterolateral approach to the tibia has been popularized for the management of tibial pilon fractures. For complex fracture patterns a combined anterolateral/anteromedial approach is suitable but a high rate of complication has been reported. In our retrospective study a two-choice strategy adopting a medial tibial approach was proposed for the treatment of pilon fractures with anterior or posterior fragmentation. METHODS: Based on an anatomic study of tibial pilon fractures, we retrospectively analyzed the fractures with primary posterior, posterior-lateral or anterior, anterior-lateral (Tillaux-Chaput) involvement of the distal tibia. This retrospective study consisted of 18 patients with a closed tibial plafond fracture. The inclusion criteria were: (1) pre- sence of an anterior/anterolateral type fragment or a posterior (Volkmann) type fragment involving larger than 25% of the articular surface, (2) a minimum follow-up of 12 months, (3) a fibula fracture associated with a medial column fracture of the distal tibia, and (4) soft tissue conditions at the time of operation that did not compromise the choice of surgical access (Tscherne classification for closed fractures: grade 0 and grade 1). Tibial plafond fractures were classified into two groups: one presenting anterior and the other with posterior rim (Volkmann) fragments. RESULTS: Most patients achieved a good clinical recovery in terms of range of motion and Olerud-Molander scale scores. Only three patients presented a grade 2 osteoarthritis at the 12 month follow-up. CONCLUSION: Our two-choice strategy highlights concepts which have been previously debated and described in the literature. But a new extended protocol for surgical approach to the distal tibia, including more fracture patterns and their association should be further investigated.

Posterior shoulder dislocation is a rare event that may occur after a direct trauma, an epileptic seizure, electric shock or electroconvulsive therapy. In more than 50% of the cases, posterior dislocations are missed on initial evaluation and often misdiagnosed as frozen shoulders with unfortunate consequences. We present the case of a missed posterior subluxation and reverse Hill Sachs lesion (McLaughlin lesion) in a 40-year-old woman caused by anelectric shock of 240 V. The patient underwent surgery in our institute two weeks after the injury. The humeral head was reduced and the reverse Hill Sachs lesion was filled by demineralized bone matrix allograft with osteoinductive factors. Tendons were repaired and a temporaneous artrodesis was performed. At the final follow up of 12 months, we obtained a Costant Score of 93 and the patient returned to her previous daily activities.

BACKGROUND: The treatment of distal femur fractures represents a challenging task. General and local factors, including bone quality, articular surface involvement, fracture comminution, associated soft tissue injuries and ultimately fixation system, all play a role in the final clinical outcome. Current surgical approaches often undermine patellar vascularization and integrity of the extensor apparatus, not guaranteeing sufficient visualization of the medial condyle. This technical note presents the efficacy and safety a new surgical technique to address distal femoral fractures. METHODS: The original "swashbuckler" surgical approach was modified in order to obtain a better visualization of the lateral and medial femoral condyles without affecting the knee extensor mechanism and the anastomotic arterial supply of the patella. This modified surgical approach was utilized in a consecutive series of patients presenting with an AO Foundation/Orthopaedic Trauma Association (AO/OTA) 33 distal femur or periprosthetic fracture of the knee. The final outcome was recorded according to a functional evaluation scoring system. RESULTS: Twelve patients (2 males and 10 females) with a mean age of 67,8 years were included in this series. The same, modified "swashbuckler" surgical approach was applied in all cases. Multiple internal fixation techniques, including a single lateral plate, a combination of a lateral and medial plate, a single lateral plate associated with lag screws, were used to obtain a satisfactory stabilization of the fracture site. All patients were reviewed at a minimum one-year follow up (median 15 months): all patients regained their level of activities of daily living. No major intraoperative or postoperative complications were recorded. CONCLUSIONS: The modified swashbuckler approach allows anatomical reduction and appropriate fixation without sacrificing the blood supply to the patella and ensures rapid weight bearing resumption thanks to an intact extensor mechanism.

The authors conducted a retrospective study on 23 patients (12 females and 11 males) with low-grade intramedullary chondrosarcoma of a long bone, treated with intralesional curettage, phenolization and cementation. The use of phenol was supported by an in vitro study, the use of bone cement by clinical studies. A consensus has been growing that this type of tumours should be treated less aggressively. The average age of the patients was 445 years (range: 29 to 71). The mean follow-up period was 6.2 years (range: 2.5 to 11 years). After 6 months the average Musculoskeletal Tumor Society (MSTS) score was 76.8% of 30, the best possible score (range: 61% to 87%). After 12 months this score increased to 89.8% (range: 63% to 100%). Complications were: one recurrence (43%), treated with a tumour prosthesis, and 3 fractures (13%). The authors strongly support this new technique, all the more as it still allows for a more radical approach, if necessary. They stress the importance of a strict follow-up by a multidisciplinary team, in order to treat local recurrences and (rarely) metastases.

From February 2017 to December 2018, 20 patients had undergone the proposed modified Wilson-SERI osteotomy technique, for moderate hallux valgus. The mean age of patients was 58,25 years (range 19 to 78). The hallux valgus angle (HVA), the intermetatarsal angle between first and second metatarsal bone (IMA) and the distal metatarsal articular angle (D.M.A.A) were measured. The feet were assessed based on the scoring system used by Broughton and Winson and by the American Orthopedic Foot and Ankle Society (AOFAS) hallux-metatarsophalangeal-interphalangeal scale. All twenty one patients were followed up postoperatively for a minimum of 12 months. The mean HVA angle decreased significantly from 31,1° before surgery (range 22.9°-40°SD 5.0) at 11,2° (range 2.5° to 22.0°SD 5.3) at twelve months follow up. The mean IMA angle decreased significantly from 12,5° (range 8.0°-18.6°SD 3.8) before surgery at 7,4° (range 3.4°-14.0°SD 2.5) at twelve months follow up. The mean DMMA angle decreased significantly from 15.1° (range 5.3° to 20.0°SD 4.4) before surgery at 7,4 °(1.5°- 10.7°SD 2.5) at twelve months follow up. The mean score according to the AOFAS forefoot was increased from 22,1 (range 13-30 SD 5.0) to 88,2 (Range 77-96 SD 5.2) (p<0.0001). No complications, like dislocations, avascular necrosis of the first metatarsal and deep venous thrombosis, were observed in the post-operative period. Short term results at twelve months after surgery are quite satisfactory but further studies are necessary, to better comprehend an overall outcome of such approach in the long run.

Purpose The aim of this study is to present clinical results of a retrospective case series that includes patients treated with an extensive modification of the Kocher lateral approach to the elbow with surgical detachment of the anterior branches of the radial collateral ligament. Methods From January 2016 to January 2018, nine patients with closed isolated displaced or multifragmentary radial head fractures (Mason type II, III, or IV) who underwent osteosynthesis or arthroplasty through a modified Kocher lateral elbow approach were available for follow-up. Results There were six female and three male patients. The median age at the time of surgery was 52 years old (range: 26-70). The dominant upper limb was injured in 22.2% of patients. After a median follow-up of 8 (range: 6-27) months, all patients regained completely all their daily activities and no cases of infections were recorded. Conclusion We believe that the approach proposed can be a useful choice to deal with these challenging injuries. Our strategy may represent a valid alternative to more popular approaches as the use of anchors decreases the risk of instability that is the major danger considered in the past when soft tissues as tendons and ligaments are detached. Level of Evidence This is a level IV study (therapeutic case series).
RESUMO
Bicondylar plateau fractures are complex injuries often requiring a challenging treatment. We report a case of a 68 year-old-male patient with a complicated tibial plateau bicondylar fracture. The fracture of the tibial plateau involved all columns (lateral, medial, posterior). The fracture pattern of the proximal tibia managed by triple plating through dual posteromedial and anterolateral incisions. Posterior-medial and the medial plating result in increased stability. The posteromedial approach to the knee that we used in our case, offers various advantages. We recommend the option of the posteromedial access, as an approach that allows excellent control of the posterior involvement of this pattern of tibial plateau fracture.

The purpose of this retrospective study was to evaluate the short and midterm radiological outcome with regards to bone healing, correlated with humeral shaft fractures treated with anterograde intramedullary nailing, when interfragmentary gap was significant. Here, we critically review our experience of short and midterm term results in over 65 year-old patients. Inclusion criteria in the study were: (1) patients over 65 years old (2) patients with displaced humeral mid shaft fractures (AO/OTA 12 A B C type fractures); (3) patients treated with closed reduction and internal fixation with intramedullary nail (Trigen Humeral Nail® Smith and Nephew) with at least two screws for proximal locking and one screw for distal locking; (4) residual interfragmentary gap, being considered significant any gap >6 mm (being 7 mm the minimum nail diameter available in our facility). Various factors were considered in our analysis: the size of the interfragmentary gap in both projections (also the mean of the measured gaps was calculated), the relationship between the greater and the mean interfragmentary gap and the second diameter measurement of the nail in the half distal part, the number of the screws in distal locking procedure, the use of a reaming procedure or not, the AO classification, the actual age at the time of surgery, the operating time, the nail second diameter as described before and its ratio with the measured residual gap. At 3 months follow-up, 4 patients showed radiographic healing (26,67%), 9 patients showed a visible callus (60%), with a total of 13 patients (86,67%) showing signs of normal recovery, the remaining 2 patient had insufficient callus formation (13,3%). At 6 months follow-up, 1 patient was missing (6,67%), although radiographic healing was already evident during the previous follow-up check, another one showed incomplete callus formation, the remaining 13 patients showed radiographic healing (86,67%), with a total of 14 patient considered healed at 6 months follow-up (93,33%). In conclusion, osteosynthesis with anterograde nail in geriatric patients appears to be a quite safe approach despite a great interfragmentary gap. After 6 months of treatment, callus formation and the overall clinical outcome were proven to be above satisfaction. (www.actabiomedica.it).

he goal of our preliminary report is to investigate hip stem stability and intra-operative cement mantle integrity after screw insertion in plate fixation of periprosthetic Vancouver B1 femur fractures. From a cohort of 50 patients with a periprosthetic femur fracture treated in our department from February 2012 until February 2017, we included in our study patients with a periprostethic Vancouver B1 femoral fracture in cemented hip arthroplasty and hemiarthroplasty, operated with ORIF using a 4.5/5.0 LCP Proximal Femoral Hook Plate ® (Synthes, Switzerland) with at least one screw perforating the cement mantle. Anteroposterior and lateral femur views and pelvis X-rays were performed preoperatively. The stability of the hip implant and the cemented mantle integrity was evaluated intra-operatively in a macroscopic way and with a post-operative X-ray in anteroposterior and lateral views. Only 7 patients satisfied the inclusion criteria; no lesion/break of the cement mantle occurred intra-operatively at any step during drilling or screw insertion, also confirmed with C-arm assessment. No cases of stem mobilization were found and cement mantle integrity was maintained in every case. Insertion of screws around a cemented stem for plate fixation in periprosthetic femur fractures Vancouver type B1 could be considered a safe procedure. However, further and more extended studies are necessary for proving additional knowledge at the evaluation of the cement mantle in osteosynthesis procedures.

The MIPO (Minimally Invasive Plate Osteosynthesis) technique for treating metadiaphyseal fractures of the proximal humerus has gained great attention during the past years. The purpose of this retrospective study was to underline all the important difficulties when the MIPO technique is applied, to propose practical solutions and to evaluate the overall clinical outcome of our patients treated with this technique. A total of 14 patients had been operated in two different surgical units, at San Carlo Borromeo Hospital (Milan, Italy - 11 patients) and in Policlinico Umberto I Hospital (Rome, Italy - 3 patients), between June 2013 and November 2016. The humeral fractures were divided according to the Maresca et al. classification system. A lateral deltoid-split or an anterolateral deltopectoral approach was performed in the proximal humerus. In distal approach, an anterior or a lateral window was performed for plate fixation. After a follow-up of 17,4 (range 3-31) months all patients showed fracture healing and there were no non-unions or infected cases. MIPO of the humerus is a tissue sparing technique and in expert hands can improve healing rates and can also reduce complications like nerve damages and infections. In conclusion, we would like to highlight the importance of the MIPO technique as a possible alternative option to the traditional ORIF technique.

The "heart" of the calcar is the internal cortical septum called "femoral thigh spur". Nevertheless, the integrity of the femoral thigh spur and its extensions in Garden I and II femoral neck fractures has not been examined in depth, in CT scan-based studies. The aim of this retrospective study is to analyze characteristics as integrity of upper thigh spur area of the intra-capsular femoral neck using precise CT scans, as well as features of the medial cortical bone interruption of orthopedic calcar, in femoral fractures that are radiographically defined as Garden type I-II.A total number of 23 patients was finally included in our study. We called it the "upper thigh spur area" the area around a 360 degree perimeter of the upper thigh spur. The above-mentioned area is a cylindrical intracapsular structure oriented parallel to the intertrocanteric line of the proximal femur . We analyzed the modification of the cortical bone in this specific intra-capsular area of the femoral neck. In all the cases the upper thigh spur area (the internal cortical septum) was intact. The medial cortical (the known "orthopedic calcar") was evaluated by CT scans in coronal views; it was found to be interrupted in 14 patients and intact in 9; among patients of the first group, 50% were classified as Garden I and 50% as Garden II. The cortical integrity on 360° of the upper thigh spur area was evaluated by CT scans in axial views through different cuts, and it was found to be intact in all cases. More extended studies including CT scans of Garden I-II-III and IV fractures are needed so as to obtain more complete results. In conclusion, it seems that the integrity of the upper thigh spur zone is associated with stable fractures.

Radiological evaluation of complex intra-articular fractures of the proximal humerus is still challenging. Here, we describe the post-operative "P" sign as a reproducible radiographical mark of a varus reduction, performed by assembling a head-shaft angulation of less than 130 degrees. Our retrospective study was conducted in a group of subjects who previously suffered from proximal humerus four-part fractures. We evaluated the post-operative evolution of specific radiographical parameters that are of crucial prognostic significance: Cervix-diaphysis angle (HHSA), quality level of the orthopaedic reduction (insufficient, sufficient and good) based on a radiological generalized subjective overview, presence of calcar screws through the Philos plate. The final cohort included a group of 39 patients of 70.76 ± 8.3 years of age and an average follow-up of 7.2 months. The post-operative mean HHSA was 131.5 ± 9.4. Interestingly, a positive correlation was detected between presence of the radiographical "P" sign in the post-operative period and the number of surgical complications coming up in the post-operative period (OR: 3.68 - I.C. 95%: 0.7984255-19.2532430), although not statistically significant. In our study, the high number of complications corresponds to literature database. Presence of the "P" sign could be a useful tool for assessing the quality of reduction during intra and post-operative radiological evaluation. We underline the importance of the "P" sign as a "quality of reduction" factor and strongly recommend its intra-operative monitoring as an additional tool together with a standard subjective evaluation of the reduction.

Incorrect or delayed diagnosis and treatment of the carpometacarpal fracture-dislocations is often associated with poor prognosis. We present a rare case of unusual pattern of injury, involving dorsal dislocation of four ulnar carpometacarpal joints, associated with fracture of the trapezium, a burst fracture of the trapezoid bone and an extra-articular fracture of the third distal of the radius. The first surgical intervention was followed by unsatisfactory results, confirmed by the CT scans. A second surgery followed and an open reduction and pinning with K wires performed. Post-operative follow up lasting for nine months revealed a very good surgical outcome.

PURPOSE: To report the midterm outcome of the Endolog system for correction of moderate-to-severe hallux valgus. METHODS: 23 women and 2 men (33 feet) aged 35 to 80 (mean, 52) years underwent minimally invasive surgery for moderate (n=25) and severe (n=8) hallux valgus using the Endolog system. The hallux valgus angle (HVA), the intermetatarsal angle (IMA), and the proximal articular set angle (PASA) were measured on radiographs. The feet were also assessed based on the American Orthopaedic Foot and Ankle Society (AOFAS) scale. RESULTS: The mean follow-up duration was 18.2 (range, 12-36) months. The mean HVA, IMA, PASA, and the mean AOFAS score improved significantly after surgery (all p<0.0001). Periosteal reaction was noted by week 4, and callus formation after 3 months. There were no delayed or non-union or other complications. CONCLUSION: The Endolog system achieved good outcome for moderate-to-severe hallux valgus.

Chondromyxoid fibromas account for <1% of primary bone neoplasms. We report one such case occurring in the distal fibula of a 27-year-old woman. The patient underwent curettage, followed by phenolisation, insertion of a Steinmann pin, and cementation. This treatment reduced morbidity, restored stability, and enabled rapid functional recovery. There was no recurrence after 2 years.
