Effectiveness of teriparatide combined with the Ilizarov technique in septic tibial non-union.

Aim The septic non-union is a common compliance in bone healing due to bone infection. Bone resection, associated with Ilizarov osteo-distraction technique, is commonly used in these cases. The aim of this study was to analyse clinical and radiological results of teriparatide in combination with the Ilizarov technique and to compare this treatment with the standard treatment. Methods Forty adult patients underwent surgery because of type C of the Association for the Study and Application of Methods of Ilizarov (ASAMI) classification non-union were enrolled. The patients were divided in two groups: those treated with Ilizarov technique (Norm group) and those treated with Ilizarov technique combined with teriparatide injection (Teri group). Surgical duration, complication rate, bone healing status, clinical and functional outcomes were assessed according to the A.S.A.M.I. classification in the mean follow-up of 12 months. The subjective quality of life was assessed by the Short Form Survey (SF)-12. Results Teri group showed less time wearing Ilizarov's frame (p <0.05) than the Norm group and a statistical significance in the inter-rater reliability Cohen's k (p>0.05) respect to Norm according the score between the bone healing and clinical outcome results. There was no statistically significant difference between the two groups in other parameters that were assessed. Conclusion A benefit of teriparatide was found as adjuvant in the treatment of septic non-union.

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.

Platet Rich Plasma or Hyperbaric Oxygen Therapy as callus accellerator in aseptic tibial non union. Evaluate of outcomes.

BACKGROUND AND AIM OF THE WORK: The incidence of long bone non-unions has been estimated to range between 5-10%. Nonunion of fracture is a delayed complication of fracture. A large bone resection, associated with Ilizarov's osteo-distraction technique, is commonly used in these cases. The war experience was very important for dealing with these injuries. The purpose of this study is to report whether the use of Platelet Rich of Plasma(PRP) or Hyperbric Oxygen Therapy(HOT) as an adjuvant to the osteogenic distraction of Ilizarov with respect to the classical method has advantages. METHODS: From 183 tibial non union, we enrolled 50 patients suffering by Type B according ASAMI non union classification.  We divided the patients into two groups. The first group was a retrospective group of patient treated by Ilizarov Tecnique plus PRP. Instead the second group, patients were treated by Ilizarov Tecnique associated with  HOT. The chosen criteria to evaluate the two groups during the clinical and radiological follow-up were: the complication after the surgery in the two groups; the duration of surgery; the objective quality Bone results and functional results were evaluated according to ASAMI classification while the subjective quality of  life correlated with Ilizarov frame function by the Short Form 12 Health Survey (SF-12); The correlation between bone regenerate/bone healing and X-rays. The evaluation endpoint was set at 12 months from the remotion of Ilizarov's frame for both groups. RESULTS: In comparing the complications  of the two populations, there were a significant statistically difference(p<0.05) in the local skin inflammation and Dockin Point Skin retraction  for HOT group while  in refracture  p<0.05 was for group PRP. From the SF-12 we discovered not statistically differences p<0.05. The average correlation between Bone Regenerate-Bone Healing/ X-rays is absolutely in the PRP as in the HOT, p>0.05. The average Time for remove Ilizarov's Frame in months was 15.37(±7.34; range 9-32) in PRP while in HOT was15.22(± 7.83; range 9-31), p>0.05. CONCLUSIONS: From our study we can conclude that the association of HOT and PRP with the Ilizarov technique does not improve the functional outcomes but allows a more rapid healing of the regenerated bone and therefore an early removal of the device and a corresponding improvement in the quality of life.

Standard plating vs. cortical strut and plating for periprosthetic knee fractures: a multicentre experience.

Aim Periprosthetic fracture after knee arthroplasty occurs more frequently in the supracondylar area of femur, especially after low energy trauma associated with torsional or compressive forces. Several techniques have been described for the treatment of displaced fractures. The aim of this study is the evaluation of the outcomes and bone healing of periprosthetic femoral fractures managed by standard plate fixation compared to plating with bone grafting. Methods Thirty-six periprosthetic fractures around the knee were selected. Eighteen patients underwent standard plate and screws fixation while other eighteen were treated by plating associate with a cortical strut. Knee Society Score (KSS) and Short Form 12 (SF12) with the UNION SCORE (RUS) were used for the evaluation of results. Results After a minimum follow-up of 12 months, the results showed a statistically significant difference in SF-12, KSS, and RUS in favour of plating associated to bone graft with respect to the plating alone; four cases of non-union were recorded in the group of patients treated by standard plating. Conclusions Our experience once again demonstrated that plating and bone grafting may ensure a mechanical and biological support for the healing of periprosthetic fracture of the knee more than simple plating.

Conservative Treatment of Spondylodiscitis: Possible Therapeutic Solution in Case of Failure of Standard Therapy.

INTRODUCTION: Spondylodiscitis (SD) is an uncommon disease but not rare, because it represents around 3-5% of all cases of osteomyelitis. Late diagnosis and/or inadequate treatment often cause irreversible damage to cause neurological deficit. Most require only conservative treatment, sometimes a surgical approach is required. AIM: The purpose of this study is to propose a conservative protocol to treat spondylodiscitis when the standard conservative treatment has failed. This alternative treatment has been for a long time at the Codivilla-Putti Institute. METHODS: We performed a prospective cohort study of 192 consecutive patients who underwent paravertebral intramuscular injections of antibiotic associated with standard treatment at our Center from January 2010 to December 2015 with SD. Of this 192 patients we selected 98 who had already undergone standard antibiotic therapy at another hospital without resolution of the disease. All patients have performed our protocol that provides a total of 3 cycles, each of 3 weeks, repeated at approximately 5 weeks apart. For each patient we evaluated Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP), White Blood Cells (WBC) indexes, SF36 and VAS Score at the beginning and at the end of the treatment. RESULTS: At a mean follow up of 22 months (range 60-12), clinical healing was achieved in 87 patients (88,9%) of cases with significant reduction in back pain and functional limitation. The VAS Score and the SF36 were better at the end of treatment compared to previous "GOLD STANDARD" treatments in the previous hospitalization in another hospital. In most cases there were slightly reduced in inflammatory indexes. CONCLUSION: There are no studies in the literature demonstrating the effective efficacy of local infiltrative treatment with antibiotics, associated with standard treatment protocol. We believe that our protocol in treating SD, favors an early functional recovery, and be able to offer more chance of success than the standard treatment.
