RESUMO

PURPOSE: Management of acute open tibial fractures with critical bone defect remains a challenge in trauma surgery. Few and heterogeneous cases have been reported about the treatment with the induced membrane technique. METHODS: We prospectively evaluated three patients treated with the induced membrane technique for acute Gustilo IIIB tibial fractures with critical bone defect. Success treatment was defined by bone union with patient pain free. Clinical and radiological evaluations were performed regularly until healing, then annually and with a minimum follow-up of five years. RESULTS: In all patients but one, a success was recorded, respectively, at four and six months. These two patients were pain free until the final follow-up, and no graft resorption or secondary complications related to the index surgery were observed. The third case was managed successfully with a bone transport technique. CONCLUSION: The induced membrane technique is an alternative good option for the treatment of these severe lesions.

RESUMO

INTRODUCTION: Anaemia in patients with trochanteric fracture is associated with increased morbidity and mortality and it is an independent risk factor for functional mobility of patients. Several authors have reported the blood loss following operative treatment comparing different fixation systems but few authors have evaluated many associated variables that could influence the perioperative blood loss. PURPOSE: To evaluate the blood loss in patients that had their trochanteric fracture stabilized with dynamic hip screw (DHS) or Gamma nail. Multivariate analysis of different variables that can influence blood loss was carried out (type of fracture, antiaggregant or anticoagulant therapy, time to surgery). The hypothesis was that there is no difference in terms of blood loss in patients with trochanteric fracture treated with DHS or Gamma nail considering all these variables. MATERIALS & METHODS: Perioperative blood loss was evaluated in 417 consecutive patients treated for trochanteric fracture with DHS or Gamma nail between January 2010 and March 2013. The perioperative blood loss was calculated using the Lisander formula modified by Foss-Kehlet based on pre- and post-operative haemoglobin values and transfusion rates. Univariate and multivariate analysis were performed integrating the following variables: type of fracture (A1 vs A2), antiaggregant/anticoagulant therapy vs no therapy, time to surgery (<24 vs >24 hours from trauma), type of implant (DHS vs Gamma nail). RESULTS: A significant blood loss (p <0.05) was observed between A1 and A2 fracture types (1247ml vs 1796.7ml), antiaggregant/anticoagulant therapy and no therapy (1592.7ml vs 1470.2ml), time-to-surgery <24 and >24 hours from trauma (1584.4ml vs 1323.9ml), DHS and Gamma nail (894.7ml vs 1720.6ml). At multivariate analysis, in the A1 fracture groups the DHS showed a significant lower blood loss compared to Gamma nail (p < 0.05). CONCLUSIONS: According to the perioperative blood loss, DHS should be used in A1 fractures while Gamma nail can be taking in account for the unstable A2 fractures.

RESUMO

PURPOSE: To review the long-term outcome of Rockwood capsular shift for recurrent shoulder dislocation secondary to trauma. METHODS: Records of 30 males and 4 females who underwent Rockwood capsular shift for recurrent (≥2 episodes) anterior shoulder dislocation were reviewed. An additional Bankart repair with different techniques was performed in 24 of the patients by 2 different surgeons. The outcome was assessed using the Western Ontario Shoulder Instability Index (WOSI) and the Western Ontario Osteoarthritis of the Shoulder (WOOS) index questionnaires, the modified Rowe score, and the Constant-Murley score. Shoulder range of motion (ROM) was measured. Degenerative joint changes were evaluated on radiographs. RESULTS: During a mean follow-up of 13 (range, 10-16) years, 6 (18%) patients had a mean of 1.2 recurrent dislocations. Four of the patients reported a traumatic event during recurrent dislocation. Of the 6 patients, 3 had undergone a Bankart lesion repair. Better Rowe and adjusted Constant scores were associated with lower age at first dislocation, at the index surgical procedure, and at follow-up. Four patients developed glenohumeral osteoarthritis: 2 were mild or moderate and 2 were severe and symptomatic. Glenohumeral osteoarthritis was associated with follow-up duration (p=0.03) and poorer Rowe score (p=0.012), adjusted Constant score (p=0.001), and WOOS score (p=0.006). CONCLUSION: Rockwood capsular shift can preserve shoulder ROM, with rates of recurrent dislocation and degenerative joint changes comparable with other techniques.

RESUMO

The management of nonunion of the forearm bones is a challenging task. Multiple factors have been associated with the establishment of forearm nonunion, such as the fracture position and complexity, general condition of the patient, and the previously utilized surgical technique. The optimal surgical treatment of a bone gap remains a subject of discussion. Autogenous corticocancellous bone grafts and vascularized bone flaps have been used with differing results. The authors describe a technique for the treatment of posttraumatic nonunion of the radius with a 5-cm bone gap using the free anterolateral thigh fascial flap wrapped around a tricortical iliac bone graft. The fracture healed after 5 weeks. The use of a vascularized tissue wrapped around the bone graft resulted in a well-healed bone and no signs of resorption after 2 years of follow-up. A bone graft wrapped by a fascial flap could magnify the restorative effect on the bone defect because of its dual role of constructing vascularization and inducing tissue regeneration.

RESUMO

The extra-articular impingement of the greater trochanter against the ileum is an underrated cause of early dislocation in total hip arthroplasty. In this preliminary study, the authors assess the effectiveness of an anterior longitudinal osteotomy of the greater trochanter for preventing dislocation. A total of 115 patients underwent a total hip arthroplasty through a posterolateral approach. All patients underwent clinical and radiological follow-up at 1, 3, and 6 months. No dislocation was reported. All patients demonstrated fast recovery of range of motion and walking. No trochanter fractures were observed. The osteotomy of the greater trochanter is an effective surgical technique that decreases anterior impingement and consequently lowers the dislocation rate in primary total hip arthroplasty.

RESUMO

The eLibra® Dynamic Knee Balancing System (Synvasive Technology, Zimmer, Warsaw, IN) is an instrument designed to address the flexion stability during a TKA. It provides an objective measurement of the soft-tissue forces in the two compartments before the final cuts are made, allowing to obtain patient-specific rotational orientation of the femoral component. Between March 2010 and March 2012, the eLibra® system was used during the implantation of 75 TKAs in 75 patients at the author's institution. Preoperative and postoperative clinical assessment were evaluated using the Knee Society Score (KSS) and the Visual Analogical Scale (VAS). Radiographic evaluation was performed with weight-bearing radiographs in antero-posterior and lateral views in order to study the presence of radiolucencies. In a sample of 20 patients, representative of the population studied, the rotation of the femoral component was measured by two independent observers using the C-arm Cone Beam CT scan (XperCT/Allura FD20 angiography system; Philips, Best, Netherlands). At a mean follow-up of 42.3 months (29-54 months), three patients died from causes not related to the surgery. We had one case of aseptic loosening three years after surgery. None of the patients reported complications peri- or postoperatively. Clinical evaluation showed an improvement in KSS scoring, from preoperative means of 48.35 and 47.53 points for clinical and functional aspects, respectively, to postoperative means of 88.03 and 91.2 points, respectively (p<0.001 for both aspects). The current study demonstrates that the use of the eLibra® device is simple and reproducible. It could help surgeons objectively quantify ligament balance and perform soft tissue-guided resection in a reproducible way, resulting in better post-operative stability and reduced complications. The use of the postoperative cone beam computed tomography (CBCT), in a representative sample of patients, revealed a specific and optimal orientation of the femoral component with a mean of 2.18° of external rotation.

RESUMO

PURPOSE: the unstable osteochondritis dissecans (OCD-type II and III according to the ICRS classification) of the knee largher than > 2.5 cm(2) in adults are uncommon lesions and there is no consensus on how to treat them. Medium-term studies have reported good results using autogenous osteochondral plugs (mosaicplasty). The aim of this study is to analyze the long-term results of this technique for the treatment of unstable OCD in a selected group of adult patients. METHODS: four patients with OCD at either one of the femoral condyles were included in this prospective study. The average age was 21.2 years (range, 18-24 years). The OCD lesions were classified as type II in three patients and type III in one patient and the average size was 3.8 cm(2) (range, 2.55-5.1 cm(2)). The lesions were treated in situ with a variable number of autogenous osteochondral plugs (Ø 4.5 mm(2)). The Modified Cincinnati, Lysholm II and Tegner scores were used for clinical and functional evaluation. Magnetic resonance arthrography (MRA) was performed before surgery and at 2, 5 and 10 years after surgery. A modified MOCART score was used to evaluate MRA findings. RESULTS: the average follow-up duration was ten years and 6 months (range, 10-11 years). No complications occurred. At the final follow-up, all scores (clinical, functional and MOCART) improved. In all but one of the patients MRA showed complete osteochondral repair. CONCLUSIONS: the fixation of large and unstable OCD lesions with mosaicplasty may be a good option for treating type II or III OCD lesions in adults. The advantages of this technique include stable fixation, promotion of blood supply to the base of the OCD fragment, and grafting of autologous cancellous bone that stimulates healing with preservation of the articular surface. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

RESUMO

The "induced membrane" technique described by Masquelet has been used successfully for many years for posttraumatic bone defect reconstruction, non-unions and osteomyelitis. The main advantages are the two-step surgical procedure that in case of primary infection allows repeated debridement if necessary, in case of internal fixation early weight bearing with decreased malalignment risk and it has a short learning curve. A theoretical application of this procedure is the management of acute severe traumatic bone loss of the limbs despite the lack of this experience in literature. We report on a Gustilo IIIB meta-epiphyseal fracture (AO 43-C3) of the leg with a 6 cm in length bone loss that was treated with the Masquelet technique.

RESUMO

Pain is a common symptom in orthopedic patients, but is managed sub-optimally, partly due to scarce opioid use in severe cases. The aim of the Orthopedic Instant Pain Survey (POIS) was to evaluate changes in pain management in Italian orthopedic practice 2 years after a legislative change (Law 38/2010) simplifying opioid access for pain control. A web-based survey on the knowledge of this law and trends observed in clinical practice for severe pain treatment was administered to 143 Italian orthopedic specialists. In total, 101 (70%) respondents showed a high level of knowledge. Nevertheless, 54.5% stated that they do not use opioids for severe osteo-articular pain management. Main barriers to opioid use are fear of adverse events (61.4%), especially nausea/vomiting and constipation, and patient resistance (29.7%). A modest knowledge of pain classification was also demonstrated. Opioid use remains very limited in Italian orthopedic practice. Physicians' fear of side effects showed poor knowledge of strategies for effective management of opioid-related adverse events, such as combined oral prolonged-release oxycodone/naloxone. Continuing educational programs could improve delivery of evidence-based pain management.

RESUMO

Mortality after hip fracture is a major problem in the Western world, but its mechanisms remain uncertain. This study assessed the 2-year mortality rate after hip fracture in elderly patients by including hospital factors (eg, intervention type, surgical delay), underlying health conditions, and, for a subset, lifestyle factors (eg, body mass index, smoking, alcohol). A total of 828 patients (183 men) 70 to 99 years old experiencing a hip fracture in 2009 in the province of Varese were included in the study. The risk factors for death were assessed through Kaplan-Meier analysis and Cox proportional hazards analysis. Hip fracture incidence per 1000 persons was higher in women (8.4 vs 3.7 in men) and in elderly patients (12.4 for 85-99 years vs 4.4 for 70-84 years). The mortality rate after 1, 6, 12, and 24 months was 4.7%, 16%, 20.7%, and 30.4%, respectively. For the province of Varese, sex (hazard ratio, 0.39 for women), age group (hazard ratio, 2.2 for 85-99 years), and Charlson Comorbidity Index score (hazard ratio, 2.06 for score greater than 1) were found to be statistically significant. The 2-year mortality rate in hip fractures is associated with sex, age, and comorbidities. Male sex, age older than 85 years, and Charlson Comorbidity Index score greater than 1 are associated with a higher risk. Surgical delay was significant in the Kaplan-Meier survival time analysis but not in the Cox hazard analysis, suggesting that early surgery reduces risk in patients with numerous comorbidities.

RESUMO

Humeral shaft aseptic nonunions occur in 2% to 10% of patients managed conservatively and 10% to 15% of patients treated surgically. The complex muscular and neurovascular anatomy of the upper limb makes the surgical approach to the fracture site demanding and risky, especially when previous surgeries have been attempted. The clinical consequence of atrophic humeral shaft nonunions is a severe functional limitation that may significantly affect activities of daily living, especially in the elderly. The surgical treatment of humeral shaft nonunions is challenging for orthopedic surgeons. Patients with atrophic nonunions require both a stable fixation and enhancement of the biologic response because of the weak biologic reaction observed at the fracture site. The gold standard of treatment in elderly patients has not been described. Nonetheless, older age and comorbidities are associated with potentially malignant nonunions. This study reports the authors' experience using opposite cortical allograft combined with bone morphogenetic protein 7 and mesenchymal stem cells to treat humeral shaft atrophic nonunions in 2 elderly patients. The nonunion site healed at 4 months (patient 1) and 8 months (patient 2) postoperatively, with full return to activities of daily living and no pain. Neither patient reported complications of the radial nerve, which is at high risk of injury during this type of surgery. The only reported complication (patient 2) was an intraoperative longitudinal partial distal humeral fracture, probably caused by compression screw overtightening. The use of a locking plate and opposite cortical allograft, combined with BMP-7 and mesenchymal stem cells, represents a safe and effective treatment for malignant nonunions in older patients.

RESUMO

Infection is a frequent cause of failure after joint replacement surgery. The infection rate after total hip arthroplasty (THA) has been reduced to 1-2% in the last years. However, it still represents a challenging problem for the orthopedic surgeon. Difficulty of therapeutic approach, and poor functional outcomes together with length of treatment and overall cost are the main burden of this issue. Even the diagnosis of an infected hip could be challenging although it is the first step of an accurate treatment. At the end, many cases require removing the implants. Afterwards, the treatment strategy varies according to authors with three different procedures: no re-implantation, immediate placement of new implants or a two-stage surgery re-implantation. Based on the most recently systematic review there is no suggestion that one- or two-stage revision methods have different re-infection outcomes. The two-stage implant-exchange protocol remains the gold standard. It is considered as the most efficacious clinical approach for the treatment of periprosthetic infection, especially in patients with sinus tracts, swelling, extended abscess formation in depth and infection of Methicillin Resistant Staphylococcus Aureus (MRSA), and other multidrug-resistant bacteria as reported in recent consensus documents.

RESUMO

We report the use of the double-pulley technique for arthroscopic fixation of the bony PASTA (partial articular surface tendon avulsion) lesion. Arthroscopic examination documented a 15-mm-long and 8-mm-wide comminuted bony avulsion with 2 main fragments. Two double-loaded suture anchors were placed with a transtendinous technique at the anterior and posterior edges of the lesion respecting the tendon insertion to the avulsed fragment. The medial sutures were retrieved through the intact supraspinatus tendon medially to the fracture. The sutures were initially coupled in a double-pulley configuration generating 2 sutures oriented from anterior to posterior; then a simple suture for each anchor oriented from medial to lateral was obtained. At the end of the procedure, the adequacy of reduction and stability of the fragments were confirmed. At 2 months from surgery, radiographic healing of the fracture was noted and integrity of the supraspinatus tendon insertion to the footprint was confirmed by arthro-magnetic resonance imaging, with full recovery of daily activities and complete active range of motion confirmed at 6 and 12 months. The double-pulley technique allows optimal reduction of bony fragments and reconstruction of normal footprint anatomy even in comminuted fractures. Moreover, it creates a waterproof reduction of the fragments, protecting the fracture site from synovial fluid.

RESUMO

PURPOSE: To evaluate the incidence of scapular dyskinesis and SICK scapula syndrome (defined as scapular malposition, infero-medial border prominence, coracoid pain and malposition, and dyskinesis of scapular movement) in patients treated surgically for acute type III AC dislocation. METHODS: Development of scapular dyskinesis and SICK scapula syndrome following conservative treatment has been described in the literature. In the present study, we evaluated 34 patients treated with different surgical techniques for acute type III AC dislocations. Functional outcome, radiographic evaluation of clavicular reduction and scapular kinematics were all evaluated. RESULTS: Scapular dyskinesis was observed in only 4 (11.7%) patients, of which only 1 (2.9% of the sample) was affected by SICK scapula syndrome. Scapular dyskinesis was classified as type I in 3 cases (75%) and type III in 1 case (25%). Constant shoulder scores (mean 95.7 points, SD ± 5.3) and Simple Shoulder Test results (mean 11.2 points, SD ± 0.8) were excellent. Recurrence of separation was observed in 4 patients. CONCLUSIONS: Surgical treatment of type III acute AC joint dislocations is associated with a lower incidence of scapular dyskinesis and SICK scapula syndrome, if compared to data reported in the literature on conservative treatment. LEVEL OF EVIDENCE: Retrospective study, Level IV.

RESUMO

Mesenchymal stem cells may differentiate into angiogenic and osteoprogenitor cells. The effectiveness of autologous pluripotent mesenchymal cells for treating bone defects has not been investigated in humans. We present a case series to evaluate the rationale of using nucleated cells from autologous bone marrow aspirates in the treatment of severe bone defects that failed to respond to traditional treatments. Ten adult patients (mean age, 49.6-years-old) with severe bone defects were included in this study. Lower limb bone defects were >or=5 cm3 in size, and upper limb defects .or=2 cm3. Before surgery, patients were tested for antibodies to common pathogens. Treatment consisted of bone allogeneic scaffold enriched with bone marrow nucleated cells harvested from the iliac crest and concentrated using an FDA-approved device. Postsurgery clinical and radiographic follow-up was performed at 1, 3, 6, and 12 months. To assess viability, morphology, and immunophenotype, bone marrow nucleated cells were cultured in vitro, tested for sterility, and assayed for the possible replication of adventitious (contaminating) viruses. In 9 of 10 patients, both clinical and radiographic healing of the bone defect along with bone graft integration were observed (mean time, 5.6 months); one patient failed to respond. No post-operative complications were observed. Bone marrow nucleated cells were enriched 4.49-fold by a single concentration step, and these enriched cells were free of microbial contamination. The immunophenotype of adherent cells was compatible with that of mesenchymal stem cells. We detected the replication of Epstein-Barr virus in 2/10 bone marrow cell cultures tested. Hepatitis B virus, cytomegalovirus, parvovirus B19, and endogenous retrovirus HERV-K replication were not detected. Overall, 470 to 1,150 million nucleated cells were grafted into each patient. This case series, with a mean follow-up of almost 2 years, demonstrates that an allogeneic bone scaffold enriched with concentrated autologous bone marrow cells obtained from the iliac crest provides orthopedic surgeons a novel option for treating important bone defects that are unresponsive to traditional therapies.

RESUMO

Chronic pain is a common healthcare problem worldwide that ranks as a predominant reason for consulting a physician, yet effective management of chronic pain remains suboptimal, often resulting in unnecessary suffering and decreased quality of life, lost productivity and excessive healthcare costs. To overcome the challenges associated with the management of chronic pain, increased awareness and both patient and physician education are required. Improving physician knowledge of pain assessment and management guided by recommendations for a comprehensive, multifactorial, personalised treatment approach involving pharmacological and non-pharmacological approaches is key to achieving effective pain relief. Guidelines for the management of non-cancer and cancer pain recommend thorough patient assessment before individualized therapy based on the type and intensity of pain. The availability of mechanism-specific analgesics has facilitated improvements in the treatment of chronic non-cancer pain, which may be of neuropathic, muscle, inflammatory, mechanical/compressive or mixed origin. Stepwise escalation of analgesic therapy (paracetamol, non-steroidal anti-inflammatory drugs, mild to strong opioids) according to the World Health Organization's three-step pain ladder remains the standard approach for the selection of treatment for chronic cancer pain, although there is now a greater awareness of the requirements for effective administration of opioids including dose titration, use of short versus long-acting opioids, opioid rotation, management of adverse effects, and ongoing monitoring. Selection of an effective, appropriate, personalized analgesic regimen for patients with chronic pain is achievable and is expected to enhance compliance, overall functioning and quality of life.

RESUMO

Chronic pain is a major healthcare issue in Europe and globally, and inadequate or undertreated pain significantly reduces the ability of many patients to participate in ordinary daily activities, adversely affects their employment status and contributes to a substantial rate of depression and anxiety in patients with chronic pain. There is a broad distinction of chronic pain into chronic non-cancer pain and chronic cancer pain, and important subgroups of these include patients with rheumatic and/or orthopaedic diseases, pain syndromes caused by cancer itself and caused by cancer treatment. Despite comprising the majority of non-cancer pain in Europe, chronic non-cancer pain associated with rheumatic diseases and/or orthopaedic conditions is often inadequately managed. Although paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) play a continuing role in the treatment of chronic rheumatic diseases, accumulating evidence of potential toxicity with both traditional non-selective NSAIDs and selective cyclooxygenase 2 inhibitors has prompted a reassessment of their use. This has particular resonance for the elderly, who are more likely to have significant pain issues than younger patients and are at high risk of NSAID-related adverse events. The use of mild opioids, such as codeine and tramadol, and strong opioids, such as morphine, hydromorphone and oxycodone, may be appropriate where paracetamol and other non-opioid analgesics are ineffective in chronic non-cancer pain. Cancer pain, either related to the underlying disease or caused by cancer treatment, is also a common cause of chronic pain in the elderly.

RESUMO

Chronic pain is a common healthcare problem worldwide that ranks as a predominant reason for consulting a physician, yet effective management of chronic pain remains suboptimal, often resulting in unnecessary suffering and decreased quality of life, lost productivity and excessive healthcare costs. To overcome the challenges associated with the management of chronic pain, increased awareness and both patient and physician education are required. Improving physician knowledge of pain assessment and management guided by recommendations for a comprehensive, multifactorial, personalised treatment approach involving pharmacological and non-pharmacological approaches is key to achieving effective pain relief. Guidelines for the management of non-cancer and cancer pain recommend thorough patient assessment before individualized therapy based on the type and intensity of pain. The availability of mechanism-specific analgesics has facilitated improvements in the treatment of chronic non-cancer pain, which may be of neuropathic, muscle, inflammatory, mechanical/compressive or mixed origin. Stepwise escalation of analgesic therapy (paracetamol, non-steroidal anti-inflammatory drugs, mild to strong opioids) according to the World Health Organization's three-step pain ladder remains the standard approach for the selection of treatment for chronic cancer pain, although there is now a greater awareness of the requirements for effective administration of opioids including dose titration, use of short versus long-acting opioids, opioid rotation, management of adverse effects, and ongoing monitoring. Selection of an effective, appropriate, personalized analgesic regimen for patients with chronic pain is achievable and is expected to enhance compliance, overall functioning and quality of life.

RESUMO

Chronic pain is a major healthcare issue in Europe and globally, and inadequate or undertreated pain significantly reduces the ability of many patients to participate in ordinary daily activities, adversely affects their employment status and contributes to a substantial rate of depression and anxiety in patients with chronic pain. There is a broad distinction of chronic pain into chronic non-cancer pain and chronic cancer pain, and important subgroups of these include patients with rheumatic and/or orthopaedic diseases, pain syndromes caused by cancer itself and caused by cancer treatment. Despite comprising the majority of non-cancer pain in Europe, chronic non-cancer pain associated with rheumatic diseases and/or orthopaedic conditions is often inadequately managed. Although paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) play a continuing role in the treatment of chronic rheumatic diseases, accumulating evidence of potential toxicity with both traditional non-selective NSAIDs and selective cyclooxygenase 2 inhibitors has prompted a reassessment of their use. This has particular resonance for the elderly, who are more likely to have significant pain issues than younger patients and are at high risk of NSAID-related adverse events. The use of mild opioids, such as codeine and tramadol, and strong opioids, such as morphine, hydromorphone and oxycodone, may be appropriate where paracetamol and other non-opioid analgesics are ineffective in chronic non-cancer pain. Cancer pain, either related to the underlying disease or caused by cancer treatment, is also a common cause of chronic pain in the elderly. An understanding of individual needs is essential in providing adequate pain relief, which is a central goal of care in all patients with chronic pain.
