The aim of this study is to report the long-term outcomes of a homogenous series of patients who underwent subtalar arthroereisis (STA) for the treatment of symptomatic flexible flatfoot (FFF). Thirty-four pediatric patients who underwent STA with a bioabsorbable implant were enrolled and radiographic measurements, clinical outcomes, and patients’ satisfaction were evaluated. At a mean 180 months follow-up, radiographic measurements showed significant improvement. A physiological footprint and a proper hindfoot alignment were shown in more than 70% of patients. Mean AOFAS score was 90.4 ± 9.2 (72–100), mean SF-12 was 44.7 with 30 out of 34 patients (88.2%) satisfied with the procedure. STA with a bioabsorbable implant showed satisfactory long-term results. Based on the data subgroup analysis, nine to 11.5 years for female and nine to 13.5 years for male appeared to be the most appropriate age for surgery.

Ullrich congenital muscular dystrophy (UCMD) is a severe form of muscular dystrophy caused by the loss of function of collagen VI, a critical component of the muscle-tendon matrix. Magnetic resonance imaging of UCMD patients’ muscles shows a peculiar rim of abnormal signal at the periphery of each muscle, and a relative sparing of the internal part. The mechanism/s involved in the early fat substitution of muscle fiber at the periphery of muscles remain elusive. We studied a muscle biopsy of the rectus femoris/deep fascia (DF) of a 3-year-old UCMD patient, with a homozygous mutation in the COL6A2 gene. By immunohistochemical and ultrastructural analysis, we found a marked fatty infiltration at the interface of the muscle with the epimysium/DF and an atrophic phenotype, primarily in fast-twitch fibers, which has never been reported before. An unexpected finding was the widespread increase of interstitial cells with long cytoplasmic processes, consistent with the telocyte phenotype. O...

Introduction One of the major concerns in the use of modular hip prostheses is the structural failure of one or more components of the prosthesis, with total mechanical failure. In literature there are sporadic cases of breakage of the prosthetic neck in patients with high functional demand. Material and methods In our experience we have implanted a model of modular hip prostheses in 38 patients. In 17 of these patients it was implanted a neck made of titanium alloy, while in the remaining 21 was utilised a CrCo neck. In 5 of the 17 patients with neck titanium it has been a spontaneous rupture of the neck in a time ranging from 12 to 24 months. We proceeded with the replacement of the titanium neck with similar neck made of CrCo alloy in 5 patients with failed neck, and we decided to call the remaining 12 patients with titanium neck, offering them the revision of the system. All patients accepted the revision surgery. Results implants explanted and subject to breakage of the neck we...

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Ceramic bearing surfaces are increasingly used for total hip replacement, notwithstanding that concern is still related to ceramic brittleness and its possible mechanical failure. The aim of this systematic review is to answer three questions: (1) Are there risk factors for ceramic component fracture following total hip replacement? (2) Is it possible to perform an early diagnosis of ceramic component failure before catastrophic fracture occurs? (3) Is it possible to draw guidelines for revision surgery after ceramic components failure? A PubMed and Google Scholar search was performed and reference citations from publications identified in the literature search were reviewed. The use of 28mm short-neck femoral head carries an incre...

Introduction Total hip arthroplasty (THA) in dysplastic hips is challenging, and each specific implant used in this context has been associated with specific complications. A registry study was performed to query survival rates, hazard ratios, and reasons for revision of different stem designs in THAs after developmental dysplasia of the hip. Materials and methods A regional arthroplasty registry was inquired about cementless THAs performed for hip dysplasia from 2000 to 2017. Patients were stratified according to stem design in tapered (TAP; wedge and rectangular), anatomic (ANAT), and conical (CON), and divided on the basis of modularity (modular, M; nonmodular, NM). In total, 2039 TAP stems (548 M and 1491 NM), 1435 ANAT (1072 M and 363 NM), and 2287 CON (1020 M and 1267 NM) implants were included. Survival rates and reasons for revisions were compared. Results The groups were homogeneous for demographics, but not fully comparable in terms of implant features. NM-CON stems showed...

INTRODUCTION Degenerative disc disease is a major health concern in spine surgery. The aim of this article is to summarize the current knowledge about injectable regenerative therapies (Mesenchymal Stem Cells -MSC- or Platelet Rich Plasma - PRP) in degenerative disc disease. EVIDENCE ACQUISITION A research and analysis of the literature on Pubmed, Medscape, MEDLINE, Google Scholar and Cochrane databases was performed, in accordance with the Preferential Reporting Items for - Systematic Reviews and Meta-analyses (PRISMA) flowchart. Only peer-reviewed randomized controlled trials (RCTs), prospective single-arm trials, case series, and cohort studies were included. EVIDENCE SYNTHESIS A total of 17 studies were included. All were homogeneous regarding indications to the procedure: discogenic low-back pain for at least 3-6 months, failure of conservative treatment, MRI evidence of disc degeneration. A total of 182 patients were treated with MSC and 198 patients were treated with PRP. Considering the efficacy, the studies were heterogeneous in clinical evaluation systems; however, they all reported significant improvement in clinical and functional scores. Neither major complications nor adverse effects were reported by any author. As for radiographical outcome none of the studies reported a disc height improvement after treatment. CONCLUSIONS Degenerative disc disease is a major health concern. Regenerative therapies could play a role in the treatment of its symptoms, as they have been proven to be clinically effective, cheap, and safe. Nevertheless, further studies are needed, in order to establish evidence based standardized treatments.

BACKGROUND Harvey Cushing and Vittorio Putti are well recognised medical eminence. The Italian orthopaedic surgeon Vittorio Putti was a promoter of modern orthopaedics and a scholar of orthopaedic history. Putti was a frequent world traveler and lecturer, and a close friend of the American neurosurgeon, pathologist and writer Dr. Harvey Cushing. Correspondence between the two surgeons can be found at Yale medical historical library and the Rizzoli Institute. METHODS A research was performed: an extensive documentation on the correspondence between the two surgeons was found. RESULTS The research allowed to analyze and confirm the strong relationship between the two surgeons and highlighted their passion for collecting antique medical books. CONCLUSIONS The present paper represents a tribute to two great surgeons in the history of medicine with the aim of describing their personality and witnessing their great friendship through an unprecedented documentation. Both surgeons still live on through those who can continue to admire and study the fruit of their passion, as both men donated their precious collection of antique texts to public institutions, Putti to the Rizzoli Orthopedic Institute in Bologna, and Cushing to Yale University.

Background: Chronic wounds are commonly associated with polymicrobial biofilm infections. In the last years, the extensive use of antibiotics has generated several antibiotic-resistant variants. To overcome this issue, alternative natural treatments have been proposed, including the use of microorganisms like probiotics. The aim of this manuscript was to review current literature concerning the application of probiotics for the treatment of infected chronic wounds. Methods: Relevant articles were searched in the Medline database using PubMed and Scholar, using the keywords “probiotics” and “wound” and “injuries”, “probiotics” and “wound” and “ulcer”, “biofilm” and “probiotics” and “wound”, “biofilm” and “ulcer” and “probiotics”, “biofilm” and “ulcer” and “probiotics”, “probiotics” and “wound”. Results: The research initially included 253 articles. After removal of duplicate studies, and selection according to specific inclusion and exclusion criteria, 19 research articles were inclu...

The cause of low back pain and the pathophysiology of lumbar pain and sciatica have recently been reconsidered basing on current knowledge on cellular and molecular mediators of inflammation. Several cytokines have been considered as potential therapeutic targets to contrast sciatica in patients with disc herniation, and supportive studies suggest a leading role of TNF-α in this contest: therefore, clinical trials have tested TNF-α inhibitors in the clinical setting of the patient with radicular pain secondary to an herniated disc. The current review deals with the autoimmune theory of disc herniation and its role in determining radiculopathy and neuropathic pain. It also reports the recent evidences that led to the introduction of anti-TNF-α drugs into the clinical setting as a biological therapy for radiculopathy and disc herniation. Targeting the TNF-α pathway has demonstrated controversial effects in the tested study population and available results only report a short-term follow-up. More confirmatory studies in terms of long-term clinical results, complications, more effective route of administration and cost-effective analysis are required to establish the real role of this biological therapy in the treatment of patients with disc herniation and neuropathy.

Multiple Myeloma (MM) typically involves the spine and causes bone pain, pathological fractures and spinal cord compression with possible consequent neurological deficits. This retrospective study reports the results of surgery on a selected population of patients who underwent surgery for symptomatic spinal myeloma. A total of 26 patients who underwent surgery for spinal myeloma with neurological involvement were studied retrospectively. Neurological evaluation was performed according to the Frankel grade. Characteristics of this population, reconstructive techniques and surgery-related complications were reviewed. The tumours involved the thoracic spine in 13 patients, the lumbar spine in 10 patients, and the cervical spine in three patients. The most common approach was a posterior-only approach (70%), followed by a staged, combined approach (20%), and an anterior-only approach (10%). The mean postoperative survival time was 43 months (range: 8-60 months). A significant improvement in neurological function was observed in the study population after surgery (p=0.001). There were seven early postoperative complications, two late complications and five surgery-related complications. Surgery in selected patients affected by spinal myeloma with neurological involvement is associated with good clinical outcomes and neurological recovery and an acceptable rate of complications. Neurological deficit and segmental instability can be treated sufficiently in most cases by the implementation of a posterior-only approach; however, the final treatment should, when possible, include adjuvant chemotherapy and radiotherapy and rigorous bracing.

The purpose of treatment for patients with skeletal metastases and pathologic fractures is a singular performance that allows for functional reconstruction. The most common surgical procedure is resection of the metastatic lesion and prosthetic reconstruction. Given the recent developments of new prosthetic implants, the metastatic disease to the proxymal humerus is more often treated surgically by the use of arthroplasty implants. The majority of patients will survive for a significant time after surgery, and hence a stable and pain-free limb should be the goal. When prosthesis implants are used, this allows for a good pain control, despite a poor functional outcome.

Background and Objectives: Diabetes mellitus is considered a serious public health problem due to its high prevalence and related complications, including gait and posture impairments due to neuropathy and vascular alterations and the subsequent increased risk of falls. The gait of patients with diabetes is characterized by alterations of the main spatiotemporal gait parameters such as gait velocity, cadence, stride time and length, which are also known to worsen with disease course. Wearable sensor systems can be used for gait analysis by providing spatiotemporal parameters and postural control (evaluated from the perspective of body sway), useful for investigating the disease progression. Thanks to their small size and low cost of their components, inertial measurement units (IMUs) are easy to wear and are cheap tools for movement analysis. Materials and Methods: The aim of this study is to review articles published in the last 21 years (from 2000 to 2021) concerning the applicati...

Aims Total hip arthroplasty (THA) patients undergoing or having a prior lumbar spine fusion (LSF) have an increased risk of mechanical complications. The aim of this registry-based, retrospective comparative cohort study is to assess the longer term survival of THA in patients who have undergone a LSF during a 17-year period (2000 to 2017). Methods A registry-based population study was conducted on 679 patients who underwent both THA and LSF surgeries. Patients were identified from the regional arthroplasty data base and cross linked to patients with LSF from the regional hospital discharge database between 2000 and 2017. Demographic data, diagnosis leading to primary THA, primary implant survival, perioperative complications, number and causes of failure, and patients requiring revision arthroplasty were collated and compared. For comparison, data from 67,919 primary THAs performed during the same time time period were also retrieved and analyzed. Results Patients undergoing THA an...

Osteitis condensans ilii (OCI) is a benign condition characterised by triangular sclerosis of the iliac bone which may mimic radiographic sacroiliitis. Prevalence is estimated between 0.9 and 2.5%, with female predominance, but the most recent article reporting original epidemiological data in the general population was published in 1971. The aim of our study is to contribute updated figures about prevalence of OCI in Italy. A retrospective review of pelvic radiographs was conducted. Consecutive patients visiting the emergency department of our Institution between 1st January and 31st December 2020 were enrolled. Individuals with a past diagnosis of axial spondyloarthritis were excluded. Presence of OCI was evaluated by two musculoskeletal radiologists. Clinical and radiologic features such as osteoarthritis and insertional enthesopathy were also assessed. We included 1047 individuals (61% female) with a median age of 74 years. OCI was present in 10 cases, accounting for a prevalence in the general population of 1.0% (95% CI 0.5–1.7). All patients with OCI were women and, in the female sample, prevalence was 1.6% (95% CI 0.7–2.8). Clinical characteristics and associated radiographic features were not different between patients with OCI and women without OCI. The prevalence of OCI observed in our study is consistent with previous literature, and we confirm that it is more frequently retrieved in women. Longitudinal research is warranted to elucidate the evolution, while knowledge about the disorder is needed to raise the awareness of rheumatologists and radiologists and to properly identify and report the condition. Key Points • OCI may mimic sacroiliitis and is a major differential diagnosis of radiographic axial spondyloarthritis. • Prevalence of OCI in our sample is 1.0%, in line with previous literature. • OCI predominantly affects women, and our study suggests that the disorder can be incidentally identified even after childbearing age. • Increased awareness of the characteristics of OCI can facilitate identification and reporting of the disorder.

BackgroundIntraoperative somatosensory evoked potential (SSEP) and transcranial motor evoked potential (tcMEP) monitoring are frequently used in spinal as well as spinal cord surgery for so-called intraoperative neuromonitoring (IONM), while the combination of these techniques is known as concomitant multimodal intraoperative monitoring (MIOM). The aim of this review is to collect available evidence concerning use of IONM and MIOM in cervical decompression surgery in the degenerative setting and attempt to identify the best practice to be advocated.Materials and methodsA review of the PubMed and MEDLINE databases and Cochrane Central Registry of Controlled Trials was performed. Studies were included if they involved patients who underwent cervical spine decompression surgery for degenerative stenosis with use of IONM or MIOM and where sensitivity/specificity was reported.ResultsIn the identified studies, the sensitivity of SSEP was estimated to be between 22 and 100% with constant specificity of 100%. In the included studies, the sensitivity of MEP was estimated to be between 78 and 100% with specificity ranging from 83.2 to 100%.ConclusionsOn the basis of available evidence, MIOM could be a helpful tool in decompression cervical spine surgery in patients affected by degenerative spinal stenosis, since it is associated with high specificity and sensitivity for detection of intraoperative neural damage. However, evidence is still lacking regarding patient selection to identify individuals in whom monitoring is indicated.Level of evidenceIV (systematic review of studies with LOE II to IV).

Background: Abductor mechanism lesions represent a severe complication after revision total hip arthroplasty (rTHA). The resulting abductor insufficiency can cause limping, pain, instability, and a higher rate of failure, thus requiring further revision surgery. In case of severe degeneration and retraction of the abductor mechanism, several different surgical treatments are needed. Aim: To systematically review all studies reporting on surgical treatment of severe abductor lesion after rTHA, focusing on surgical techniques, and clinical and functional results. Method: Scientific databases were accessed in December 2018 to identify studies addressing the surgical management of severe abductor disruption after rTHA. The PRISMA guidelines were followed. Data were extracted from the identified articles and summarised. Only data about patients with symptoms of abductor insufficiency after rTHA were included in the database. Results: 9 retrospective studies were included, all being retro...

Even though internal fixation has expanded the indications for cervical spine surgery, it carries the risks of fracture or migration, with associated potential life threatening complications. Removal of metal work from the cervical spine is required in case of failure of internal fixation, but it can become challenging, especially when a great amount of scar tissue is present because of previous surgery and radiotherapy. We report a 16 year old competitive basketball athlete who underwent a combined anterior and posterior approach for resection of an osteosarcoma of the sixth cervical vertebra. Fourteen years after the index procedure, the patient eliminated spontaneously one screw through the intestinal tract via an oesophageal perforation and developed a severe dysphagia. Three revision surgeries were performed to remove the anterior plate because of the great amount of post-surgery and post-irradiation fibrosis. Screw migration and oesophageal perforation after cervical spine sur...

Introduction The outcomes of total hip replacement in patients suffering from residual poliomyelitis are poorly covered in the literature. In this retrospective study we posed the question of whether total hip replacement performed for degenerative hip diseases in limbs with residual poliomyelitis could determine satisfactory mid-term clinical and radiographic results, with a reasonable complication rate. Methods A retrospective study was carried out to assess the results of 14 total hip replacements performed on 14 patients with residual poliomyelitis on the involved limb from June 1999 to September 2011. Average age at the time of surgery was 51 years (range 26-66 years). Mean duration of follow-up was 92 months (range 52-156 months). Surgery was performed through a direct lateral approach on all hips. All but one were cementless implants. Results 2 implants failed, 1 due to traumatic acetabular fracture 6 days after surgery, and 1 due to aseptic cup loosening 13 years after surge...

Subjective tinnitus and cervical spine disorders (CSD) are among the most common complaints encountered by physicians. Although the relationship between tinnitus and CSD has attracted great interest during the past several years, the pathogenesis of tinnitus induced by CSD remains unclear. Conceivably, CSD could trigger a somatosensory pathway-induced disinhibition of dorsal cochlear nucleus (DCN) activity in the auditory pathway; furthermore, CSD can cause inner ear blood impairment induced by vertebral arteries hemodynamic alterations and trigeminal irritation. In genetically -predisposed CSD patients with reduced serotoninergic tone, signals from chronically stimulated DCNs could activate specific cortical neuronal networks and plastic neural changes resulting in tinnitus. Therefore, an early specific tailored CSD treatments and/or boosting serotoninergic activity may be required to prevent the creation of 'tinnitus memory circuits' in CSD patients.

The use of intermediate screws in fractured vertebrae has been proposed to decrease the number of fused levels in thoracolumbar fractures and to enable short fixations. The aim of this study was to evaluate the results of this technique and to establish predictive factors involved in loss of segmental kyphosis correction (LKC). Forty-three patients who underwent short-segment spinal fixation with intermediate screws for a thoracolumbar spine fracture in a two-year time period were enrolled in the study. Patients had AO-type A3, A4 and B2 thoracolumbar fractures. Radiological parameters included segmental kyphosis (SK), vertebral wedge angle (VWA) and loss of anterior and posterior vertebral body height. Patients were evaluated up to one-year follow-up. The correlation between LKC and potential risk factors, such as smoking habit, sex, age, neurological status and BMI was evaluated. Mean preoperative SK was 16.5°±6.5°, and it decreased to 3.4°±3.5° postoperatively (P<0.01). At the one-year follow-up mean SK dropped to 5.5°±3.9° (P<0.01). Mean preoperative VWA was 20.0°±8.1°, and significantly improved to 6.3°±3.1° after surgery (P<0.01). There was a mean LKC of 1.8°±2.1°at one year. LKC mildly correlated with body mass index (BMI, r: +0.31), and obese patients (BMI>30) had an increased risk of LKC at the one-year follow-up (P=0.03; odds ratio [OR]=3.2). Analysis of the radiological data at one-year follow-up showed that all the evaluated parameters were associated with a mild loss of correction, with no impact on the clinical outcomes or implant failure. These findings confirm the trends reported in the literature. The correlation between LKC and clinical features, such as BMI, age, sex, smoking habit and preoperative neurological status was investigated. Interestingly, a positive correlation was observed between BMI and LKC, and obese patients with BMI>30 had an increased risk of LKC at one-year follow-up (OR 3.2); to our knowledge this finding has never before been reported. Short-segment fixation with intermediate screws is a viable technique with positive clinical and radiological outcomes at one-year follow-up. However, surgeons should be aware that in obese patients (BMI>30) this technique is associated with an increased risk of LKC. 3.
