The Bisaccia and Meccariello technique in pediatric femoral shaft fractures with intramedullary titanium nail osteosynthesis linked external-fixator (IOLE): validity and reliability.

BACKGROUND: Over the last 20 years, the incidence of pediatric femoral shaft fractures was increased, due to changes in the children's daily activities. The healing times are different according to the chosen treatment and to other factors such as age, type of fracture, the involvement of the soft tissues, and concomitance with other injuries. The Bisaccia and Meccariello technique ( Intramedullary titanium nail Osteosynthesis Linked External-fixator -IOLE) was born to prevent rotationally and lengthening malunion or nonunion in the treatment of pediatric femoral shaft fractures. The aim or the objective of this paper is to compare the IOLE with the two most used methods for the treatment of femoral fractures in children. METHODS: From 2000 to 2016, 58 pediatric patients with femoral shaft fractures were surgically treated and enrolled in the study. The ranged age of the patients was between 3 and 15 years. Twenty-two patients were treated with endomedullary titanium nails (TEN), 16 with external axial or modular external fixators and 14 patients treated with IOLE technique. The IOLE technique is the hybridization of titanium intramedullary nails with a modular external fixator. It is divided into three phases, the first revenue given the length of the femur with the external fixator; the second, the rotations are dominated by the elastic nails; and the third finally they are hybridized on the external fixator. Comparing the three groups, radiographic images were taken to assess fracture reduction and consolidation.  RESULTS: At the final follow-up, there were no differences between three groups in terms of significant rotation defects, angulation, growth, and/or nonunion but there was a statistical in IOLE groups for the early weight-bearing. CONCLUSIONS: The Bisaccia- Meccariello technique (IOLE) showed to lead to healing the pediatric femoral shaft fracture of the femur but allows an early weight-bearing to these patients and normal life like that.

A new prognostic pelvic injury outcome score.

Aim To propose a new prognostic classification system for pelvic injuries based on a new detailed and all-encompassing evaluation of the injury pelvic outcome score and to check the prognostic value of this classification and evaluate its reliability and reproducibility. Methods From January 2017 to June 2020 from 156 pelvic fractures treated at our hospitals, 98 patients with pelvic fractures were recruited according to inclusion and exclusion criteria. All patients compiled three scores (New Score System, Majeed Score, SF-12) sessions two times during the hospital stay to evaluate the endpoint before the trauma and two years after the trauma. All patients carried out three tests independently. The evaluation of three scores included a pelvic and general complication after the surgery, the times needed to compile three score system. For reliability of the new score systems we evaluated the inter-observer or intraobserver agreement, the prediction strength of each score, and a prognostic value. Results A total of 98 patients were enrolled (74 were males and 24 females) with mean age of 43.6 (±18.6) (range 16-75) years. Tau B Kendall value was 0.827 for the new score system, 0.673 for the Majeed score, 0.746 for SF-12, there was p<0.05 for the new score system. Conclusion The new score system is prognostic, reliable, reproducible and can become a useful instrument to adequately correlate the long-term outcomes of pelvic injury fractures. Also, it provides a better evaluation of pain, work, sexual possibilities and satisfaction, balance-sitting-walking and psychological status.

A Lasso-Loop Traction Technique for Arthroscopic Superior Capsular Reconstruction.

Irreparable rotator cuff tears (RCTs) cause shoulder pain and disfunction. Management of RCT patients has classically been difficult due to few treatment options. Since Mihata et al. in 2013 introduced the superior capsular reconstruction (SCR) technique as a treatment option, it has become widespread among surgeons, especially for young active patients in whom reverse shoulder arthroplasty is not recommended. With SCR, a reduced humeral head can be maintained and superior displacement is avoided, improving shoulder pain and restoring active shoulder motion. A variety of grafts may be used, but the surgery can be technically complicated. An arthroscopic lasso-loop traction technique for SCR is described here, which simplifies graft shoulder reduction by traction from the anteromedial and posteromedial portals.

Tibial diaphyseal fractures in children: indications and limitations of the treatment with monolateral and hybrid external fixator.

Aim To report our indications and limitations about the use of external fixation in children. Methods It was retrospectively reviewed all tibial fractures treated with monolateral and hybrid external fixator, at our three Centres. It was included 32 fractures which did not show an acceptable reduction after an attempt under anaesthesia. The exclusion criteria were: open fractures, children with previous fractures of the lower limbs, with skeletal congenital diseases, fractures involving the physis and with neurovascular involvement. All fractures were classified according to the AO (Arbeitsgemeinschaft für Osteosynthesefragen) classification. An outcome was evaluated according to the time needed to obtain radiographic bone healing, the range of motion (ROM) of the ankle, the asymmetry of the lower limbs, the malunion, and complications. Results The average time of consolidation was 10.66 weeks (6-17 weeks). There were no cases of deep infection, but only seven cases of superficial pin infections. No patients reported loss of ROM of the knee or ankle. We had zero cases of residual angle greater than 5°, and in all cases the difference in length between the limbs was <1 cm. Conclusion The external fixation is a viable technique in the treatment of tibial fractures in children. Therefore, the external fixation, both monolateral and hybrid, should be considered a viable treatment for this type of fracture.

Strut graft vs. traditional plating in the management of periprosthetic humeral fractures: a multicentric cohort study.

Aim The gradual increase in shoulder implants in active elderly patients has appeared in a parallel increase in periprosthetic humeral fractures. The aim of this study was to investigate the advantages of using strut grafting with plate fixation during periprosthetic humerus fractures. Methods Thirty patients diagnosed with periprosthetic humeral fracture were divided into two groups. The first group of 15 patients (PS) underwent plate, ring, screws and strut allografts. The second group with resting 15 patients (PWS) was treated with only plate and screws. The criteria to evaluate the groups during followup were the Constant Shoulder Score (CSS) and Oxford Shoulder Score (OSS); the bone healing was measured by X-rays, controls measured by radiographic union score (RUS), and complications. The follow up was terminated at 12nd month in both groups. Results The difference between the two groups in all parameters was not significant. However, all patients gained adequate shoulder motor skills for normal daily living activities. All fractures were healed. Only two complications were registered, and blood loss was minimal. Conclusion We believe a revision to reverse shoulder prosthesis with a long-stem implant with or without cortical strut allograft augmentation to be safe and appropriate in the management of these complex injuries, though technically challenging, and having good results for normal activities daily life.

Surgical treatment of multifragmentary segmental femur shaft fractures with ORIF and bone graft versus MIPO: a prospective control-group study.

Aim Multifragmentary segmental femoral shaft fracture is a high energy injury frequently associated with life-threatening conditions. The aim of this study was to compare the use of bio metallic open reduction internal fixation (ORIF) (plate with allograft bone strut) with minimally invasive plate osteosynthesis (MIPO) fixation for the treatment of multi-segmental femoral shaft fracture in terms of outcomes, bone healing and complications. Methods Forty patients with segmental femoral shaft fractures were included and divided into two groups: 20 patients treated with ORIF+, 20 with MIPO. All fractures were classified according to AO (Arbeitsgemeinschaft für Osteosynthesefragen) and Winquist and Hansen Classification. Evaluation criteria were: duration of follow up and surgery, Non-Union Scoring System, Pain Visual Analogic Scale (VAS), objective quality of life and hip function, subjective quality of life and knee function, quality of life the Short Form-12 Survey Questionnaires (SF-12), bone healing and femoral alignment (radiographs), Radiographic Union Score for Hip (RUSH). Results Better results of ORIF in terms of complication rate, RUSH, VAS, regression between RUSH and VAS, average correlation clinical-radiographic results and patients' outcomes (Cohen k) were obtained, and similar results for the length of follow up, surgery duration, perioperative blood transfusion, wound healing. No statistical difference for Harris Hip Score (HHS), Knee Society Score (KSS), quality of life (SF-12). Conclusions The ORIF and bone strut allograft technique had better results compared to the MIPO technique with regards to complication rate, RUSH, VAS, regression between RUSH and VAS, and average correlation clinical-radiographic results and patients' outcomes (Cohen k) in the surgical treatment of multifragmentary segmental femoral shaft fractures.

Feasibility and value of non-locking retrograde nail vs. locking retrograde nail in fixation of distal third femoral shaft fractures: radiographic, bone densitometry and clinical outcome assessments.

Aim Distal femoral shaft fractures are characterized by increasing incidence and complexity and are still considered a challenging problem. No consensus on best surgical option has been achieved. The aim of this study is to investigate mineral bone densitometry, radiographic and clinical outcomes of locking retrograde intramedullary nailing (LRN) and non-locking retrograde intramedullary nailing (NLRN) regarding surgical treatment of distal femoral shaft fractures in adults based on the hypothesis that there is no statistical difference among the results of both surgical options. Methods Retrospective study: 30 patients divided into 2 groups (Group 1 LRN, Group 2 NLRN). Average age was 42.67±18.32 for Group 1 and 44.27±15.11 for Group 2 (range of age 18-65 for both groups). Gender ratio (male:female) was 2.75 (11:4) for both groups. AO Classification, Non Union Scoring System (NUSS) and Radiographic Union Score Hip (RUSH), Visual Analogic Score (VAS), Dexa scans, plain radiographs were used. Evaluation endpoint: 12 months after surgery. Results No statistical difference was obtained in terms of surgery time, transfusions or wound healing. There were similar results regarding average time of bone healing, RUSH scores, VAS, regression between RUSH and VAS, average correlation clinical-radiographic results and patients outcomes. Only one patient of LRN group had reduction of mineral bone densitometry values. Conclusion No statistical difference in terms of radiographic, bone densitometry and clinical outcomes among LNR and NLNR for the treatment of distal femur fractures was found. The presence of no statistical difference regarding radiological findings is the main factor supporting our hypothesis given their strong objectivity.

Validity and Reliability of Mini-Invasive Surgery Assisted by Ultrasound in Achilles Tendon Rupture.

INTRODUCTION: The surgical treatment for Achilles tendon rupture has become very popular in the last years, because of the good outcomes and the low re-rupture rate. AIM: The aim of this study is to compare the results between open surgery and percutaneous ultrasound-assisted surgery. METHODS: All patients who underwent an Achilles tendon surgical repair in the last 3 years were included, resulting in a total of 56 patients (40 M and 16 F) with an average age of 53 years. Of these patients, 36 were treated with an open suture, while 20 with a mini invasive ultrasound assisted suture. At a minimum follow-up of one year, patients were evaluated echografically, using both the Achilles Tendon Rupture Total score (ATRS) and the McComis score, and performing the ultrasounds bilaterally to assess both the structure and the diameter of tendons. RESULTS: Both groups of patients showed an average ATRS score >80. The McComis score was 54.18 vs. 56.25 (p>0.05). Plantar flexion and dorsal flexion work were not similar (p>0.05). On average, the calf circumference of the operated side was decreased compared to the healthy side between the groups (p>0.05). The thickness of the operated tendons evaluated with ultrasound measurement compared to the average tendon, (p <0.05). CONCLUSION: The ultrasound-assisted tenorrhaphy is a reliable treatment with good clinical and functional outcomes; anyway, the percutaneous technique and the open surgery show similar results.

Challenges in the management of floating knee injuries: Results of treatment and outcomes of 224 consecutive cases in 10 years.

INTRODUCTION: Floating knee is a flail knee joint resulting from fractures of the shafts or adjacent metaphyses of the femur and the ipsilateral tibia. It is usually associated with several complications and mortality. This study was designed to present our experience with the treatment of this injury. MATERIAL AND METHOD: This study was performed between January 2004 and December 2014. 224 cases of floating knee injuries gathered from the 34,480 lower extremities trauma files were studied, and the target information recorded. The injuries most frequently occurred in subjects between 16 and 35 years of age (60.71%), and in male subjects (85.71%). The most frequent mechanism of injury was traffic accident (92.85%). External fixation was the common type of treatment (82.14%) in emergency or as a definitive treatment. The treatment was performed within 24 h of the trauma. We performed a 36-month follow up with clinical examination, radiographs, assessing the complications, and using the Modified Cincinnati Rating System Questionnaire (MCRSQ) and the Karlström/Olerud Score (KOS) to evaluate the progression of the outcomes. RESULTS: Early complications included 8 cases of compartment syndrome, 60 open fractures and 24 partially amputated limbs. A total amputation was performed in 3 patients. The most common late complication was heterotopic calcifications of the knee (n = 68, 30.6%). Good scores for MCRSQ and KOS were obtained only after patients were sent to a reference center for knee surgery. CONCLUSIONS: Our experience revealed that the complication rate associated with floatingknee injuries remains high, regardless of the performed treatment. Surgeons should focus on reducing complications while treating these severe injuries.

Five year long term results of total joint arthroplasties in the treatment of trapeziometacarpal osteoarthritis.

INTRODUCTION: Trapeziometacarpal (TMC) osteoarthritis is a common disease. Patients with advanced disease who have failed conservative treatment have different surgical options, including total joint prosthesis. The aim of this study was to investigate the long-term outcome and complications of trapeziometacarpal (TMC) total arthroplasty. MATERIALS AND METHODS: One hundred and forty-seven patients with TMC osteoarthritis were surgically treated with TMC arthroplasty, and one hundred and thirty-seven patients were seen for follow-up (102 women and 35 men). At follow -up patients were asked to complete a visual linearanalogue scale (VAS) for satisfaction with the result of the operation and persisting pain from the thumb, the Spanish validated Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire was used to evaluate function of the affected hand.(9) The radiological examination consisted of posterior-anterior and oblique radiographs. In preoperative radiographs Eaton-Little was used, and in postoperative radiographs were assessed with regard to implant loosening and alignment. RESULTS: The subjective outcome was satisfactory in 126 cases (92 %), 14 (12 %) patients would undergo the same procedure in the other hand. The DASH questionnaireswere 19.55 (range 5.6-33,5) on average, and EVA was 1 on average. The mean key pinch strength was 5.8 Kg at 5 years follow-up. The most frequent postoperative complication was De Quervain tenosynovitis (21%), other complications were: Cup loosening (3.6%), traumatic dislocation (3,6%). The prosthesis was removed in nine cases (7%). There were four intraoperative complications. The survival rate for ARPE prosthesis was 92,7% at 60,5 months. TMC total arthroplasty offers a reliable treatment alternative in patients with thumb carpometacarpal joint osteoarthrosis which conservatives' treatment had failed. CONCLUSIONS: The TMC joint prosthesis is an option for patients with TCM osteoarthritis, provides satisfactory outcomes and has a low failure rate.(www.actabiomedica.it).
