Long bone metastases are a disease of high social importance. The goals of surgical treatment are to relieve pain, maintain or restore joint function, and prevent or treat pathological fractures. "Oligometastases" is a disease with a limited number (3-5) of metastatic lesions in the same body district, where an aggressive treatment can be carried out with "curative" intent. This study aimed to evaluate patients with bone metastases surgically treated to determine how surgical treatment can influence prognosis and quality of life, comparing solitary metastasis, oligometastases, and multiple metastases.This is a retrospective analysis of 130 patients with long bone metastases surgically treated between October 2015 and August 2019: 40 patients had solitary metastasis; 38 had less than three metastases (oligometastases), and 52 had multiple metastases. Surgery was resection and reconstruction with a cemented prosthesis (95) or nailing (35).Overall survival was significantly better in patients with solitary metastasis or oligometastases than in those with multiple metastases (p0.0001). Patients treated with resection and prosthesis had significantly better survival than those treated with nailing (p0.0001). Implant complications requiring surgical revision occurred in 20 patients treated with prostheses, while no complications occurred in patients treated with nailing.Survival of cancer patients has improved in the last two decades, leading to an increase of diagnosed metastases. Patients with oligometastases have a survival similar to those with a single metastasis. Optimal implants survival curves should stay above the curves of patients survival.Since there are no differences in survival, patients with oligometastases should be treated as patients with a solitary lesion, with more aggressive surgery (wide resection and reconstruction with prosthesis). Intramedullary nailing is still indicated in metaphyseal or diaphyseal metastases in patients with advanced disease or poor prognosis when the life expectancy does not overcome the expected survival of the nail, avoiding the need for further surgery.

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.

Purpose Calcaneal fractures are one of the most challenging injuries to treat and one of the most divisive. The purpose of this historical review is to highlight the evidence of calcaneal fracture and its treatment through history. Methods Archaeological, religious, artistic, literary and historical accounts were searched for descriptions of calcaneal fracture to give a thorough overview of the subject. The scientific literature was searched to highlight the evolution of treatment techniques. Results For over 2500 years, the only available option was conservative treatment due to the high risk of infection and limb loss in a world without antibiotics, plastic surgery techniques and adequate osteosynthesis devices. At the beginning of the twentieth century, treatment was still rather crude, consisting of closed reduction by impaction by a Cotton’s mallet, immobilisation of the foot into presses and strict bed rest in a plaster cast for five weeks. Only in the case of untreatable pain, triple arthrodesis could be employed. Regardless, the results were dismal. The debate on the superiority of open reduction and primary subtalar arthrodesis over open and closed reduction spans the entire history of medicine. Conclusion The long path of history has brought great improvement in the treatment of calcaneus fracture, but the debate about the best treatment is far from being over. There is a lack of good quality randomised control trials conducted according to an agreed set of outcome scores despite some excellent efforts. Therefore, despite the attempts made over the years and new, more precise prognostic scores, the outcomes of each technique in use today are as unique as the individuals who suffer from a calcaneal fracture.

(1) Background: Pelvic Chondrosarcomas (CS) have a poor prognosis. The grade is the most important survival predictor; other factors are periacetabular location and Dedifferentiated CS subtype. The aim of the study is to investigate a series of CS of the pelvis, to analyze the prognostic factors that affect outcomes and to demonstrate how the use of intraoperative navigation can reduce the complications without worse outcomes. (2) Methods: Retrospective study on 35 patients (21 M, 14 F), median age at surgery 54 years (IQR 41–65), with pelvic CS, treated with hemipelvectomy under navigation guidance. (3) Results: 30 high-grade CS and 5 low-grade CS; mean follow-up 51.4 months. There was a positive linear correlation between the tumor volume and the presence of local recurrence at follow-up. The mean survival time of patients with larger chondrosarcoma volume was lower, but not significantly so. Lower MSTS score was associated with significantly lower survival time (p < 0.001). (4) Conclusion: in this series overall survival, LR and distant metastasis were comparable with recent literature, while complication rate was lower compared to similar series without the use of navigation. There was a correlation between tumor volume and local recurrence rate but not with the presence of metastasis at follow up.

Objective Several studies have been published regarding the treatment of medial ulnar collateral ligament (MUCL) injuries for professional overhead athletes. However, there is a paucity of data regarding non‐professional athletes. The aim of this systematic review was to compare the rate of outcome scores and complications of conservative versus operative treatments both in non‐professional athletes and in non‐sport‐related trauma patients with MUCL lesions. Methods A systematic review of the published literature was performed by applying the PRISMA guidelines. A search was conducted using three databases: Medline, Science Direct, and Web of Science. The keywords used were “ulnar collateral ligament injury,” “elbow,” “surgery,” and “conservative treatment”. Patients were divided into three groups: patients who underwent conservative treatment (C‐group), surgical treatment (S‐group), and surgery after a failed conservative treatment (C&S‐group). Clinical outcomes were analyzed: Disability of Arm, Shoulder and Hand (DASH), Conway scale, Carson score, and Kerlan–Jobe Orthopaedic Clinic score (KJOC). Results A total of 15 studies were included, evaluating 513 patients. Although good and excellent outcomes were found for most patients during daily and/or sport activities, independently of the type of treatment, the C‐group had better results. Excellent results were found in 98.8% of the C‐group, in 88.1% of the S‐group, and in 87.7% of the C&S‐group. The complication rate in the C‐group was statistically higher compared to the S and C&S groups (P

Hamstring Strain Injuries (HSIs) are the most common type of lesion in professional footballers and the leading cause of absence days from sports. However, recent studies have shown that high-level football teams apparently do not apply any HSI prevention protocol. The aim of the study was to determine the effect of preventive strategies and protocols in reducing the incidence of hamstring muscle injuries in professional and semi-professional football teams. A literature search of PubMed/MEDLINE, ISI/Web of Science and Scopus databases was conducted with the keywords “hamstring* and (injury* or strain) and prevent* and (soccer or football)”. Quality and bias assessment was completed through the Kennelly modified scale. The Injury Incidence Rate (IIR) and the Incidence Rate Ratio (IRR) were assessed in the statistical analysis. In the meta-analysis, data were extracted, pooled and analysed with “Comprehensive Meta-Analysis Version 3.3.070” software. In total, 8 of the 1017 original search studies met the inclusion criteria of this review. The total exposure of the studies was 170,221.8 h, while the number of HSIs recorded was 165 in the intervention groups and 224 in the control groups. The average score of the quality assessment was 23.6/34. The meta-analysis of six of the eight included studies provided strong evidence that interventions are effective in reducing hamstring injuries. The IRR of the effect size was 0.443, with p-value = 0.001. The studies analysed applied different preventive strategies: the Nordic hamstring exercise, the FIFA 11+ programme and exercises for core stability or balance training. All these interventions proved to have a successful effect on prevention of hamstring injuries.

Pelvic tumors are rare entities. The rates of cure for malignant tumors involving the pelvis are often lower than those involving the extremities, with significant morbidity and mortality. This may be due to the complexity of the anatomy of the pelvis and the usually large tumor volume, making resection with adequate margins very difficult. Management of these patients requires a multidisciplinary approach and should be treated at centers specialized in musculoskeletal oncology. This chapter will focus on the surgical principles and approaches in the management of pelvic tumors.

Introduction The aim of this retrospective study was to evaluate long-term outcomes and complications of a single-center and single-surgeon patient series of isolated and comminuted tibial fractures with bone defects or tibial deformities treated by Ilizarov bone transport. Materials and methods Data from a consecutive series of patients with isolated comminuted tibial fractures (Fracture Group: FG) or deformities (Deformity Group: DG) treated between 1987 and 2002 were included. For clinical assessment, the Lower Extremities Functional Scale was used; complications were recorded according to the Dindo classification and statistical analysis was performed. Results Overall, 72 patients were enrolled with a mean follow-up of 21.6 years (range 15–30) a mean LEFS of 36.4 (range 0–100). In the FG, the mean LEFS was 21.3 (range 0–98.75), and the external fixation time (EFT) lasted 7.6 months (range 3–18 months) months. In the DG, the mean LEFS was 76.7 (range 55–100), and the EFT was 10.6 months (range 3–20 months). Between the two groups, the clinical evaluation was significantly different, while the EFT was not (p = 0.14). In the FG, the worst results were obtained in the cases of open fractures with a higher percentage of complications and the need for further surgical procedures. The cumulative rate of complications was 55.6% during the first 36 months and 66.7% at the minimum follow-up of 180 months. Conclusions Ilizarov bone transport, even at a long follow-up period, proved to be an effective technique for both definitive treatment of comminuted tibial fractures with bone defects or tibial deformities. Although our functional outcomes were lower in patients with exposed fractures, they were in line with the literature, but not influenced by the EFT when properly managed. Most complications occurred during the first 3 years; however, they could also arise much later, even until almost 30 years.
