The Evaluation and Management of Lung Metastases in Patients with Giant Cell Tumors of Bone in the Denosumab Era.

Giant cell tumor of bone (GCTB) is characterized by uncertain biological behavior due to its local aggressiveness and metastasizing potential. In this study, we conducted a meta-analysis of the contemporary literature to evaluate all management strategies for GCTB metastases. A combination of the terms "lung metastases", "giant cell tumor", "bone", "treatment", and "oncologic outcomes" returned 133 patients meeting our inclusion criteria: 64 males and 69 females, with a median age of 28 years (7-63), at the onset of primary GCTB. Lung metastases typically occur at a mean interval of 26 months (range: 0-143 months) after treatment of the primary site, commonly presenting as multiple and bilateral lesions. Various treatment approaches, including surgery, chemotherapy, radiotherapy, and drug administration, were employed, while 35 patients underwent routine monitoring only. Upon a mean follow-up of about 7 years (range: 1-32 years), 90% of patients were found to be alive, while 10% had died. Death occurred in 25% of patients who had chemotherapy, whereas 96% of those not treated or treated with Denosumab alone were alive at a mean follow-up of 6 years (range: 1-19 years). Given the typically favorable prognosis of lung metastases in patients with GCTB, additional interventions beyond a histological diagnosis confirmation may not be needed. Denosumab, by reducing the progression of the disease, can play a pivotal role in averting or delaying lung failure.

When Is a Two-Stage Surgical Procedure Indicated in the Treatment of Pseudotumors of the Hip? A Retrospective Study of 21 Cases and a Review of the Literature.

(1) Background: A pseudotumor of the hip is a sterile, non-neoplastic soft tissue mass associated with total hip arthroplasties. Pseudotumors may mimic soft tissue tumors or infections, and thus a differential diagnosis is crucial, and biopsy is recommended. The purpose of this study was to compare the complications and functional results between one-stage and two-stage procedures. (2) Methods: We retrospectively analyzed 21 patients surgically treated at our institution with "pseudotumors" associated with hip prosthesis (8 male, 13 female with a mean age of 69 years). One-stage revision was performed in 10 cases and two-stage reversion in 10, with excision only in 1 case. Complications were classified as major and minor and functional results assessed using the Harris Hip Score (HHS). (3) Results: Five patients (24%) reported major complications. The survival rate for all complications was 75%. The overall survival rate was 95% at 5 years. The mean HHS ranged from 35 pre-op to 75 post-op, highlighting improved functional results in all cases. We recorded no differences in complications or functional outcomes between the one- and two-stage procedures. (4) Conclusions: In our experience, the two-stage surgical approach is preferable in cases with major bone defects and larger pseudotumor sizes. The use of custom-made 3D-printed prostheses is increasing and is a further reason to prefer two-stage revision.

Primary vascular tumors of bone: A comprehensive literature review on classification, diagnosis and treatment.

Primary vascular tumors of bone are a heterogeneous group of neoplasms, ranging from benign hemangiomas to frankly malignant epithelioid hemangioendotheliomas and angiosarcomas. Over the years, their classification has been a matter of discussion, due to morphologic similarities and uncertainty regarding biologic behavior. Over the past decade, with the development of next-generation sequencing, there has been a significant improvement in the molecular characterization of these lesions. The integration of their morphologic, immunohistochemical and molecular features has led to a better stratification, with important prognostic and therapeutic implications. Nevertheless, primary vascular bone tumors still represent a challenge for medical oncologists. Given their rarity and heterogeneity, in the last few years, there has been no significant progress in medical treatment options, so further research is needed. Here we present a review of the current knowledge regarding primary vascular tumors of the bone, correlating clinicopathologic features with tumor behavior and therapeutic approaches.

Young para-athletes display more hedonic well-being than people with disabilities not taking part in competitive sports: insights from a multi-country survey.

Hedonic well-being relates to how individuals experience and rate their lives. People with disabilities due to their pathology may more frequently suffer from anxiety and depressive disorders than their able-bodied counterparts. Sports participation is an essential way to cope with disability. On the other hand, compared with their able-bodied peers, para-athletes undergo a unique series of stressors. Little is known in terms of hedonic well-being in this specific population. We present the results of a multi-country survey of self-perceived hedonic well-being by para-athletes of different sports disciplines and a control group (disabled individuals not playing competitive sports), using the "Psychological General Well-Being Index" (PGWBI). We included 1,208 participants, aged 17.39 years, 58.4% male, 41.6% female, and 70.3% para-athletes. Para-athletes exhibited higher well-being than disabled people, for all domains of the PGWBI scale. The nature of disability/impairment was significant, with those with acquired disability reporting lower well-being. Those taking part in wheelchair basketball, para-athletics, and para-swimming competitions had a higher likelihood of reporting well-being, whereas those engaged in wheelchair rugby exhibited lower well-being compared with controls. This large-scale investigation can enable a better understanding of the self-perceived hedonic well-being of disabled people.

An Institutional Standardised Protocol for the Treatment of Acute Displaced Midshaft Clavicle Fractures (ADMCFs): Conservative or Surgical Management for Active Patients?

BACKGROUND AND OBJECTIVES: The treatment of acute displaced midshaft clavicle fractures (ADMCFs) is still under debate. The aim of this study was to verify the effectiveness of our institutional protocol by comparing the clinical and radiographic outcomes of two groups of patients with ADMCFs treated operatively and non-operatively. MATERIALS AND METHODS: active patients with a traumatic, isolated non-pathological ADMCF with at least 1-year clinical and radiographic follow up were included. Surgical treatment was performed in the cases where the residual displacement was higher than 140% after the application of a figure-of-eight bandage (F8-B). All other cases were treated conservatively with a F8-B. A total of 134 patients were enrolled and divided into two groups: surgical and conservative groups, with 59 and 75 patients, respectively. Radiological and clinical parameters were evaluated. RESULTS: Good clinical (Constant-Murley Score, the Quick Disability of the Arm, Shoulder and Hand score, and VAS satisfaction) and radiographic outcomes (initial and residual shortening, initial and residual displacement) were obtained for ADMCFs in both groups. Multivariate analysis showed that patients treated conservatively had better clinical outcomes compared to surgically treated patients (p < 0.001). Return to sports was longer in those treated with surgery. Initial shortening was found to impact clinical outcomes as well as initial displacement. None of the patients showed signs of non-union in both groups. CONCLUSIONS: Very good mid-term clinical results can be obtained in adult patients with ADMCFs, conservatively or operatively managed, by applying our institutional treatment protocol based on objective radiographic parameters evaluated in the ER.

Vertebra Plana: A Narrative Clinical and Imaging Overview among Possible Differential Diagnoses.

Vertebra plana is a rare radiologic condition characterized by a uniform loss of height of a vertebral body that represents a diagnostic challenge for surgeons. The purpose of this study was to review all possible differential diagnoses that may present with a vertebra plana (VP) described in the current literature. For that purpose, we performed a narrative literature review in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, analyzing 602 articles. Patient demographics, clinical presentation, imaging characteristics and diagnoses were investigated. VP is not a pathognomonic feature of Langerhans cell histiocytosis, but other oncologic and non-oncologic conditions should be considered. The list of differential diagnoses, based on our literature review, can be recalled with the mnemonic HEIGHT OF HOMO: H-Histiocytosis; E-Ewing's sarcoma; I-Infection; G-Giant cell tumor; H-Hematologic neoplasms; T-Tuberculosis; O-Osteogenesis imperfecta; F-Fracture; H-Hemangioma; O-Osteoblastoma; M-Metastasis; O-Osteomyelitis, chronic.

Flatfoot over the centuries: the background of current conservative and operative treatments.

PURPOSE: Although flatfoot is a widespread human condition, historical medical texts and ancient illustrations on this deformity are extremely rare. Nowadays, doubts regarding its management remain unsolved. This historical review aims to identify the presence of pes planus since the prehistoric era and examine the treatments proposed over the centuries up to the present. METHOD: For this propose, we performed an extensive electronic search of the relevant literature, complemented by a manual search of additional sources from archaeological to artistic, literary, historical, and scientific accounts, describing flatfoot and its treatment in different eras. RESULTS: Flatfoot accompanied the evolutionary timeline of human species: from Lucy Australopithecus to Homo Sapiens. It was described among various diseases suffered by Tutankhamun (1343-1324 B.C.), while the first anatomical description dates to Emperor Trajan (53-117 A.D.) and the medical studies of Galen (129-201 A.D.). It was also represented in the anatomical drawings of Leonardo da Vinci (1452-1519) and Girolamo Fabrici d'Acquapendente (1533-1619). Historically, the conservative treatment by insoles was the only one proposed until the nineteenth century. Since then, the most popular surgical procedures performed for correction have been osteotomies, arthrodesis, arthrorisis, and tendon lengthening and transfer. CONCLUSION: During the centuries, conservative therapeutic strategies have not radically changed in their substance, while operative ones have become the protagonists during the twentieth century up to the present. Nevertheless, after more than 2000 years of history, there is no consensus regarding the best indication for the flatfoot and if it really needs to be treated.

Malignant Bone and Soft Tissue Lesions of the Foot.

Malignant tumors of the foot are rare pathologies that can involve the skin, soft tissue, or bone. Due to their rarity, they are often misdiagnosed, resulting in inadequate excision and poor outcomes. A correct approach with a careful examination and radiological study, followed by a properly performed biopsy, is thus mandatory to avoid these pitfalls. The present article reviews the most common malignant bone and soft tissue lesions of the foot region, discussing their clinicopathological presentation, imaging features, and current concepts in treatment.

History of the management of talar fractures: from the fall of king Darius to Garibaldi's bullet and from the earliest to current operative strategies.

PURPOSE: This historical review aims to highlight the important roles of the talus in antiquity and to summarise the multiple attempts of managing talar fractures throughout history. METHOD: Archaeological, religious, artistic, literary, historical and scientific accounts were searched for the descriptions of talus fractures in different eras and their treatments to provide a thorough analysis of the evolution of trauma care up to the present. RESULTS: This review shows how the talus has always had an important role in several societies: it was used as a die or considered to have a divinatory function in Mesopotamian civilisations, among Greeks and Romans, in Mongolia and in pre-Columbian Americas. Famous talus fractures are recorded in Herodotus' Histories and in the Acts of the Apostles. We report the earliest injuries described and the first operative managements between 1600 and 1800, including the one that saved Garibaldi's life in 1862, until the modern osteosynthesis by the first screws and nails and the current fixation by plating. CONCLUSION: The blooming of orthopaedic surgery at the end of nineteenth century and the high volume of traumas managed in the World Wars brought a better understanding of fracture patterns and their operative treatment. By the work of Hawkins and his classification, the introduction of the CT scan, a better knowledge of injury modalities and bone vascularisation, these challenging injuries finally land in the contemporary era without mysteries. The subsequently developed surgical procedures, although not guaranteeing success, greatly reduce the risk of necrosis and complication rate, improving patient outcomes.

Sublingual Sufentanil Tablet System (SSTS-Zalviso®) for Postoperative Analgesia after Orthopedic Surgery: A Retrospective Study.

Background: The aim of this study is to compare sublingual sufentanil and the administration device for its delivery (SSST-Zalviso®) with the traditional strategies used for the control of postoperative pain to establish if there is an actual benefit for the patient and healthcare personnel. Materials and Methods: A retrospective study was conducted to compare the efficacy of SSTS in the management of postoperative pain after orthopedic surgery between October 2018 and June 2020. We analyzed 50 patients who underwent a total knee arthroplasty (TKA). The control group consisted of 21 patients who underwent TKA and during the hospitalized recovery received a continuous femoral nerve block (cFNB). The statistical study was conducted with a level of significance p = 0.05 using "U" test, Mann−Whitney, to verify if patients had a better control of pain and fewer calls for rescue analgesia. Results: Patients involved in the study showed a significant reduction in pain intensity with the use of SSTS in the 24 h following surgery (p = 0.0568), also a drastic drop of the calls for rescue analgesia (p < 0.0001) reduces the number of calls for its control. Conclusions: This study demonstrates how SSTS might reduce pain intensity in the first 24 h after surgery and reduce the number of calls for its control, indicating better analgesic coverage and implying reduced interventions from healthcare personnel. This could allow a redistribution of resources and a reduction in the use of analgesic drugs in wards where the SSTS is used.

Treatment of Distal Radius Fractures with Bridging External Fixator with Optional Percutaneous K-Wires: What Are the Right Indications for Patient Age, Gender, Dominant Limb and Injury Pattern?

The aim of this retrospective study was to evaluate the medium-term clinical and functional outcomes of patients with closed, displaced, and unstable, simple or complex, intra- and extra-articular distal radius fractures (DRFs) treated with a bridging external fixator (BEF) and optional K-wires (KWs). AO classification was used to differentiate the injuries radiographically. Clinical-functional outcomes were evaluated using the Patient-Rated Wrist and Hand Evaluation Score (PRWHE Score) and the Quick Disabilities of the Arm Shoulder and Hand Score (QuickDASH). A total of 269 dorsally displaced fractures of 202 female (75%) and 67 male subjects (25%) were included, with a mean follow-up of 58.0 months. Seventy-five patients (28%) were treated by additional KWs. No differences were found comparing the two groups of patients (BEF vs. BEF + KWs) regarding age, sex, and fracture side (dominant vs. non-dominant). PRWHE and QuickDASH scores were lower in the BEF + KWs group compared to the BEF group (p < 0.0001 and p = 0.0007, respectively). Thus, patients treated with KWs had a better clinical outcome. Beta multivariate regression analysis confirmed that patients of the BEF + KWs group exhibited a better PRWHE score but not a better QuickDASH score. Patients treated by the BEF + KWs with the fracture on the dominant site were characterised by better clinical outcomes. Older patients had a better PRWHE score independently from the treatment. Our findings suggest that the use of BEF for DRFs with optional KWs can be indicated in both young and elderly patients of any gender, independent of limb side and fracture pattern. As the best functional results were achieved in the elderly when KWs were added, the combination of BEF and KWs seems to be mainly indicated for the treatment of DRF, also complex, in the elderly population.

Vascular Complications Caused by Tibial Osteochondroma: Focus on the Literature and Presentation of a Popliteal Artery Thrombosis with Acute Lower Limb Ischemia.

Osteochondromas are common benign bone tumors, frequently found in adolescents or young adults. Most often asymptomatic and discovered by accidental findings, they may be diagnosed because of compression or dislocation. Vascular complications are an atypical presentation of osteochondromas, and include vessel perforation and thrombosis, arterial thromboembolic events and pseudoaneurysm formation. Popliteal artery thrombosis and acute lower limb ischemia caused by a tibial osteochondroma are rarely observed. Starting from a case of temporary lower extremity ischaemia caused by thrombosis of the subarticular popliteal artery due to an osteochondroma of the proximal tibial protruding in popliteal fossa, we focused a literature analysis on diagnostic and management aspects. A combined vascular-orthopedic approach was performed with intra-arterial locoregional thrombolytic therapy and then a surgical tangential resection of the tibial osteochondroma. The adequate approach for these patients includes clinical evaluation, plain radiographs, CT scan and MRI. The purpose of the present review article is to underline the importance of a combined vascular-orthopedic approach to correct diagnosis and prompt surgical management of vascular complications caused by tibial osteochondromas.

Long Term Clinical-Functional and Ultrasound Outcomes in Recreational Athletes after Achilles Tendon Rupture: Ma and Griffith versus Tenolig.

Background and Objectives: The purpose of this retrospective study was to compare the long-term clinical-functional and ultrasound outcomes of recreational athletes treated with two percutaneous techniques: Ma and Griffith (M&G) and the Tenolig technique (TT). Materials and Methods: recreational athletes, between 18 and 50 years of age, affected by acute Achilles tendon rupture (AATR), treated by M&G or Tenolig techniques were recruited. Clinical-functional outcomes were evaluated using Achilles Tendon Rupture Score (ATRS), AOFAS Ankle-Hindfoot score, VAS (for pain and satisfaction) questionnaires, and ultrasound analysis (focal thickening, hypoechoic areas, presence of calcifications, tendinitis and alteration of normal fibrillar architecture). Results: 90 patients were included: 50 treated by M&G, 40 by TT. In all, 90% of patients resumed sports activities, with pre-injury levels in 56% of cases after M&G and in 60% after TT. In the M&G group, the averages of the questionnaires were ATRS 90.70 points, AOFAS 91.03, VAS satisfaction 7.08, and VAS pain 1.58. In the TT group: ATRS 90.38 points, AOFAS 90.28, VAS satisfaction 7.76, and VAS pain 1.34. The TT group showed a significantly higher satisfaction and return to sport activities within a shorter time. In the M&G group, ultrasound check showed a significantly greater incidence of thickening and an alteration of fibrillar architecture in the treated tendon. Three infections were reported, including one deep after M&G, two superficial in the TT group, and two re-ruptures in the Tenolig group following a further trauma. Conclusions: At long-term follow-up, M&G and TT are both valid techniques for the treatment of AATRs in recreational athletes, achieving comparable clinical-functional results. However, TT seems to have a higher patient satisfaction rate, a faster return to sports and physical activities, and fewer ultrasound signs of tendinitis. Finally, the cost of the device makes this technique more expensive.

Overall Disability Sum Score for Clinical Assessment of Neurological Involvement in Eosinophilic Granulomatosis With Polyangiitis.

AIM: The aim of this study was to verify the application of Overall Disability Sum Score (ODSS) for standardized clinical assessment of neurological involvement in patients with eosinophilic granulomatosis with polyangiitis (EGPA) and its correlation with treatment response and long-term outcomes. METHODS: Consecutive EGPA patients referred to our tertiary vasculitis center were retrospectively evaluated. Patients' neurological damage and disability were systematically assessed with Vasculitis Damage Index and ODSS. RESULTS: Fifty EGPA patients were included in the study with a median follow-up of 75 months (9-180 months). Twenty-five (50%) developed peripheral neuropathy, 17 (68%) presented mononeuritis multiplex, whereas 8 (32%) had symmetric polyneuropathy. Patients with neurological involvement were older (56.3 ± 13.4 vs. 44.4 ± 12.1 years, P < 0.0009), more frequently antineutrophil cytoplasmic antibody positive (48% vs. 16%, P = 0.015), and were more likely to have renal involvement (24% vs. 0%, P = 0.022). An early clinical response to therapy was observed within 6 months of treatment, resulting in a significant decrease in ODSS, which fell from the baseline value of 4.2 ± 2.4 to 2.9 ± 1.5 (P = 0.0001), whereas only a slow decreasing pattern was noted over the long-term period. However, all subjects developed neurological impairment and disability despite remission from active vasculitis. Patients with ODSS of greater than 3 at baseline (n = 13 [52%]) retained a higher score at the last examination (P < 0.001), predicting a low therapeutic response. Furthermore, ODSS of greater than 3 was found associated with more neurological relapses (53.8% vs. 0%, P = 0.027). CONCLUSION: Overall Disability Sum Score could be a rapid, simple, reliable instrument to evaluate the severity of disability and nerve damage due to neurological involvement caused by vasculitis and to predict, at presentation, improvement and risk of neurological worsening.
