ABSTRACT
Total hip arthroplasty (THA) is one of the most successful elective operations in orthopedic surgery for improving pain and functional disability in patients with end-stage joint disease. However, dislocation continues to be a troublesome complication after THA, as it is a leading cause of revision and is associated with substantial social, health, and economic costs. It is a relatively rare, usually early occurrence that depends on both the patients' characteristics and the surgical aspects. The most recent and important finding is the special attention to be given preoperatively to spinopelvic mobility, which is closely related to the incidence of dislocation. Consequently, clinical and radiographic assessment of the lumbar spine is mandatory to identify an altered pelvic tilt that could suggest a different positioning of the cup. Lumbar spinal fusion is currently considered a risk factor for dislocation and revision regardless of whether it is performed prior to or after THA. Surgical options for its treatment and prevention include the use of prostheses with large diameter of femoral head size, dual mobility constructs, constrained liners, and modular neck stems.
ABSTRACT
BACKGROUND: Glenohumeral osteoarthritis (GOA) is associated with disabling shoulder pain that affects everyday life. Its management comprises various treatment approaches, both conservative and surgical. Regenerative medicine has gained a major role in the conservative treatment of osteoarthritis. Intra-articular injection of adipose-derived mesenchymal stem cells (ADMSCs) is a widely used regenerative medicine approach. The aim of this retrospective study was to report the safety and clinical outcomes of intra-articular injection of ADMSCs in patients with GOA over 36-months. METHODS: This retrospective observational study involved patients with chronic shoulder pain resistant to standard conservative treatment and a diagnosis of concentric GOA, who received an intra-articular injection of autologous micro-fragmented adipose tissue (µFAT). The values of the Constant-Murley score (CMS), the visual analog scale (VAS), and the simple shoulder test (SST), collected at baseline and at 12, 24, and 36 months, were analyzed to assess treatment efficacy. The single assessment numeric evaluation (SANE) was used to rate patient satisfaction. The Friedman test was used to compare observations of CMS, VAS, and SST values repeated on the same subjects. The significance threshold was set at 0.05. RESULTS: The participants were 65 patients with a mean age of 54.19 years and a nearly equal gender distribution. Most had mild concentric GOA classified as Samilson-Prieto grade 1. The mean follow-up duration was 44.25 months. The postoperative clinical scores showed significant improvement. At 36 months, the CMS was 84.60, the VAS score was 3.34, and the SST score was 10.15 (all p < 0.0001). The SANE score at 36 months indicated that 54 patients (83.08%) were completely satisfied with the treatment. CONCLUSION: ADMSC treatment exerted favorable effects on the clinical outcomes of patients with GOA, providing pain relief and improving shoulder function. Our data support its use as a conservative treatment option for osteoarthritis.
ABSTRACT
Periprosthetic joint infection (PJI) is a serious complication following hip arthroplasty, which is associated with significant health cost, morbidity and mortality. There is currently no consensus in the optimal definition of PJI, and establishing diagnosis is challenging because of conflicting guidelines, numerous tests, and limited evidence, with no single test providing a sensitivity and specificity of 100%. Consequently, the diagnosis of PJI is based on a combination of clinical data, laboratory results from peripheral blood and synovial fluid, microbiological culture, histological evaluation of periprosthetic tissue, radiological investigations, and intraoperative findings. Usually, a sinus tract communicating with the prosthesis and two positive cultures for the same pathogen were regarded as major criteria for the diagnosis, but, in recent years, the availability of new serum and synovial biomarkers as well as molecular methods have shown encouraging results. Culture-negative PJI occurs in 5-12% of cases and is caused by low-grade infection as well as by previous or concomitant antibiotic therapy. Unfortunately, delay in diagnosis of PJI is associated with poorer outcomes. In this article, the current knowledge in epidemiology, pathogenesis, classification, and diagnosis of prosthetic hip infections is reviewed.

BACKGROUND AND AIM: Different total knee arthroplasty (TKA) implants were created for the treatment of severe symptomatic gonarthrosis and Medial Pivot TKA (MP TKA) seem to reproduce the normal kinematics of the knee. We compare two different prosthetic designs of MP TKA in order to identify whether there is a difference between the two in terms of degree of patient satisfaction. Methods: A total of 89 patients were analyzed. A group of 46 patients who benefited from a TKA with the Evolution® prosthesis and one of 43 patients who received a TKA with the Persona® prosthesis. KSS, OKS, FJS and the ROM were analyzed at follow up. RESULTS: The values of KSS and OKS were similar between the two groups (p>0,05). Our statistical analysis revealed a statistically significant increase (p <0.05) in ROM in the Persona® group and in FJS in the Evolution® group. No radiolucent lines were observed in both groups at the radiological final follow-up. Conclusions: MP TKA models analysed are a valuable tool to achieve satisfactory clinical outcomes. This study demonstrates that the FJS is an important score for the evaluation of patient's satisfaction: a ROM's limitation can be accepted by the patient in exchange for a more natural perceived knee.

Hallux rigidus (HR) is a painful condition associated with degenerative arthritis of the first metatarsophalangeal (MTP1) joint, leading to a progressive loss of dorsiflexion. The etiological factors leading to the development of the condition are not yet fully understood in the literature. When the hindfoot is aligned in excessive valgus, the medial border of the foot tends to roll over, which brings to increased stress on the medial side of the MTP1 joint, and consequently on the first ray (FR), thus potentially influencing the development of HR deformity. This state of art aims to analyze the influence of FR instability and hindfoot valgus in HR development. From the results of the analyzed studies, it appears that a FR instability may predispose the big toe to increased stress and to narrow the proximal phalanx motion on the first metatarsal, which brings to compression and ultimately degeneration of the MTP1 joint, mostly in advanced stages of disease, less in mild or moderate HR patients. A strong correlation between a pronated foot and MTP1 joint pain was found; forefoot hypermobility during the propulsion phase may promote MTP1 joint instability and increase pain. Thus, the increased moment of pronation of the foot with the overload of the medial column, when present, should be corrected conservatively or surgically; this, most likely, would be useful not only to eliminate or at least limit the painful symptoms but above all to prevent the worsening of the condition, also after the surgical treatment of HR.

BACKGROUND: Latarjet surgery and capsuloplasty are both valid alternatives for the treatment of anterior shoulder instability with limited glenoid bone loss, although in literature there is extensive discussion on it. The purpose of this study was to compare the outcomes of these procedures in patients with similar lesions. METHODS: Between January 2000 to October 2020, 59 nonconsecutive patients suffering from anterior shoulder instability were treated, 33 had arthroscopic capsuloplasty (Group 1) and 26 had open Latarjet procedure (Group 2). The Group 1 was composed by 12% of female and 88% of males with the mean age at surgery 25.6 +/- 9.07 (15-49 years). In the Group 2, the 100% of patients were males with mean age 32.42 +/- 10.74 (16-56). Rowe Score, UCLA score and WOSI score were used to test patients. RESULTS: Only UCLA (average was 22.18 ± 6.13 for the Capsuloplasty and 26.76 ± 6.57 in the Latarjet, p = 0.01) and ROWE scores (average was 70.15 ± 24.75 in Latarjet and 50.15 ± 24.70 in Capsuloplasty, p = 0.002) showed a statistically significant difference between the two procedures, while the WOSI (mean results of Latarjet 0.31 ± 0.16 against 0.24 ± 0.09 of the capsuloplasty, p = 0.069) there was no significant difference between the two groups in question. CONCLUSIONS: Apparently, the Latarjet surgery is better in terms of instability recurrence compared to capsuloplasty but has higher rate of shoulder joint osteoarthtritis. However, there are no significant differences that could decree which procedure is better. (www.actabiomedica.it).

BACKGROUND AND AIM: Displaced femoral neck fracture (FNF) is a common and significant health issue especially in older population because of the high rates of mortality and complications. The standard surgical treatment is total or partial hip replacement, including a cemented or uncemented stem. The cemented prosthesis is considered the safer option because of a lower rate of periprosthetic fractures (PPFs) as well as an actually reduced risk of bone cement implantation syndrome (BCIS). This retrospective study aims to assess the efficacy and safety of cemented versus uncemented femoral stem for FNF in patients ≥70 years. METHODS: 139 patients affected by displaced FNF underwent hip replacement, receiving 89 cemented (64%) and 50 uncemented (36%) stems. Inclusion criteria were: ≥70 years of age, an ICD-9-CM diagnose code 820.00, 820.01, 820.02, 820.03, 820.10, 820.8, and a minimum 1-year follow-up. A p value <0.05 was considered statistically significant. RESULTS: Surgical time, overall perioperative complication rate with a particular focus on the thromboembolic events, and PPFs incidence were evaluated comparing cemented and uncemented group. No difference in duration of surgery was found. Intraoperative complications were not detected. Pulmonary embolism and deep vein thrombosis were observed each in 1 case of cemented prosthesis. Periprosthetic femoral fractures occurred only in the uncemented group postoperatively, with a statistically significant difference (p<0.05). CONCLUSIONS: The low incidence of BCIS and the higher risk of postoperative PPFs in cemented and uncemented stems, respectively, suggest that the use of cementation is a safer procedure.
ABSTRACT
BACKGROUND: Distal radius fractures (DRFs) are a common challenge in orthopaedic trauma care, yet for those fractures that are treated nonoperatively, strong evidence to guide cast treatment is still lacking. AIM: To compare the efficacy of below elbow cast (BEC) and above elbow cast (AEC) in maintaining reduction of manipulated DRFs. METHODS: We conducted a prospective, monocentric, randomized, parallel-group, open label, blinded, noninferiority trial comparing the efficacy of BEC and AEC in the nonoperative treatment of DRFs. Two hundred and eighty patients > 18 years of age diagnosed with DRFs were successfully randomized and included for analysis over a 3-year period. Noninferiority thresholds were defined as a 2 mm difference for radial length (RL), a 3° difference for radial inclination (RI), and volar tilt (VT). The trial is registered at Clinicaltrials.gov (NCT03468023). RESULTS: One hundred and forty-three patients were treated with BEC, and 137 were treated with AEC. The mean time of immobilization was 33 d. The mean loss of RL, RI, and VT was 1.59 mm, 2.83°, and 4.11° for BEC and 1.63 mm, 2.54°, and 3.52° for AEC, respectively. The end treatment differences between BEC and AEC in RL, RI, and VT loss were respectively 0.04 mm (95%CI: -0.36-0.44), -0.29° (95%CI: -1.03-0.45), and 0.59° (95%CI: -1.39-2.57), and they were all below the prefixed noninferiority thresholds. The rate of loss of reduction was similar. CONCLUSION: BEC performs as well as AEC in maintaining the reduction of a manipulated DRF. Being more comfortable to patients, BEC may be preferable for nonoperative treatment of DRFs.
ABSTRACT
Intraprosthetic dislocation (IPD) is a specific implant-related complication of dual mobility (DM) implants, which is defined as a dissociation of polyethylene (PE) liner from the femoral head. We report a unique case of late IPD of a monoblock DM cup cemented into a well-fixed cementless acetabular shell for recurrent dislocation of total hip arthroplasty (THA). A 77-year-old woman was admitted to our department for acute right hip pain, functional impairment and inability to bear weight without any trauma. Three years earlier, she underwent revision THA for recurrent dislocation with a monoblock DM cup cemented into a well-fixed cementless acetabular shell according to the "double-socket" technique. Three months after that revision the patient experienced an anterior THA dislocation, which was managed by closed reduction under sedation in the emergency room. No additional episodes of prosthesis instability occurred. Upon admission, radiographic evaluation showed right THA dislocation. X-rays performed after closed reduction revealed eccentric positioning of the head inside the cup, and a direct contact between the metal head and the cup was revealed by subsequent CT scan, confirming the suspicion of IPD. The patient underwent revision surgery, during which the PE liner was found lodged within the cup in a subluxated position, disassembled from the inner head. Both the acetabular cup and modular femoral stem proved well-fixed and impossible to remove, therefore they were retained. The explanted DM components were replaced with new ones of the same size and, thanks to the femoral neck's modular nature, it was substituted with a longer one, which resulted in improved stability against intraoperative stress maneuvers. The postoperative course was uncomplicated. At 1-year follow-up, the patient had a good functional recovery.

BACKGROUND: Hallux rigidus (HR) is a degenerative arthritis of the first metatarsophalangeal joint (MTP1) with progressive loss of range of movement (ROM). Interposition arthroplasty (IA) is a technique widely used for the treatment of HR;however, few studies reported long-term clinical results. This study aims to report the clinical results of IA using a bovine pericardium collagen matrix for HR with a minimum 10-years follow-up. METHODS: Thirty patients (31 feet) who underwent IA using a bovine pericardium collagen matrix from 2001 to 2009 were retrospectively evaluated with a mean follow up of 154.1 ± 28.6 (range 124-218) months. All HR ranged from grade II to grade III, according to Regnauld classification. All patients were clinically assessed with the American Orthopedic Foot and Ankle Society Hallux Metatarsophalangeal- Interphalangeal Scale, a pain Visual Analog Scale, and the Foot and Ankle Disability Index. Scores before and after treatment, respectively achieved from clinical records and clinical evaluation at final follow-up were compared. RESULTS: At final follow-up, an improvement of all the considered scores (p < 0.01) was recorded. The overall rate of unsatisfying results was 16.1 %. Two (6.4 %) patients complained discomfort due to first ray shortening and 3 (9.7 %) cases of persistent metatarsal pain. There was one (3.2 %) case of Complex Regional Pain Syndrome (CPRS). No revision surgeries, infection, or other adverse events were reported. CONCLUSION: Interposition arthroplasty using bovine collagenous membrane is a reliable solution for high-grade HR with durable results over 10 years in more than 80 % of patients.

BACKGROUND: Surgical treatment of proximal humeral fractures (PHF) is a challenge for orthopaedic surgeons. Despite the wide application of open reduction and internal fixation with locking plates, the optimal surgical approach of PHF is still debated. This study aims to evaluate the radiological outcomes, defined as anatomical restoration of the greater tuberosity and humeral head-shaft angle, of the deltopectoral (DPA) and the lateral transdeltoid (LTA) approaches in three- and four-part PHF, treated with locking plate. MATERIALS AND METHODS: This retrospective series review identifies 74 PHF surgically treated between January 2012 and December 2019. Patients were divided into two groups according to the surgical approach (DPA vs LTA). Demographic data, duration of surgery, radiological pre- and post-surgery parameters (greater tuberosity displacement and humeral head-shaft angle) were collected. The association between the surgical approach and the quality of fractures reduction was assessed. RESULTS: The use of LTA approach correlates with a better reduction of greater tuberosity displacements compare to DPA (63% in DPA vs 100% LTA). No significant association was found with the humeral head-shaft angle (restored in 89% of the patients in DPA and 86% in LTA group), and surgical times (range 40 - 210 minutes ± DS 33,56 for the DPA; range 45 - 170 minutes ± 29,60 for LTA). CONCLUSIONS: The results of this radiological study suggest that PHF with significant displacement of the grater tuberosity could benefit from the adoption of a lateral transdeltoid approach for the ORIF procedure. Further studies are needed to confirm these findings.

The management of penetrating skeletal extremity trauma is a clinical challenge even for experienced surgeons. While the treatment of associated vascular injuries should be prioritized, there is still a lack of evidence regarding the management of foreign bodies in case of bone fractures or neurological injuries. Here we present a case of impalement of the right proximal humerus with a construction steel rod. The 54-year-old man was successfully treated without vascular, neurological, and thoracic sequelae. A review of the current literature about the most appropriate extrication sequences and soft tissue reconstruction following massive foreign body injuries was carried out.

BACKGROUND AND AIM: The treatment of irreparable massive rotator cuff tears (MIRCTs) represents a challenge for the orthopedic surgeon both for the affected population and for the intrinsic characteristics of the injury. There are different types of treatment ranging from bursectomy to reverse shoulder prosthesis and subacromial spacers. The aim of the work is to establish the clinical and functional improvement of patients treated with subacromial spacer. METHODS: we conducted 2 studies: the first analyzing a sample of 24 patients (14 females and 10 male, mean age 65.7 years) operated between 2015 and 2017 whose last follow up dates back to October 2021 and a second one analyzing 55 patients (including patients of the first sample) (30 females and 25 males, mean age 64 years) over a period of time from 2015 to 2021. The mean follow up was 56 months. All patients were diagnosed with irreparable massive rotator cuff tears and treated with subacromial spacer. RESULTS: the result in both studies was an increase of Constant score, tripled from the pre-operative values, in ROM, doubled, and a reduction of VAS. CONCLUSIONS: the clinical results are encouraging and the use of the subacromial spacer could be a valid surgical alternative for patients with MIRCTs. However, we needed randomized trials with long-term follow-up.

BACKGROUND: The number of shoulder arthroscopies is steadily increasing to treat glenohumeral joint disorders, among which the rotator cuff tear is the most common. The prevalence of this condition ranges from 13% to 37% in the general population without considering the number of asymptomatic patients. The gold standard procedure for rotator cuff repair is still undefined. The purpose of this study is to evaluate a population who underwent a single row (SR) rotator cuff repair and correlate their clinical results with MRI findings. MATERIALS AND METHODS: Sixty-seven consecutive rotator cuff procedures were retrospectively selected. All patients were diagnosed with a full-thickness rotator cuff tear and subsequently treated with an arthroscopic SR repair technique. Each patient was clinically assessed with the DASH questionnaire and the Constant-Murley Score to grade their satisfaction. Moreover, rotator cuff repair integrity was evaluated by MRI and graded using the Sugaya score. RESULTS: Mean follow-up was 19.5 ± 5.7 months. The mean Constant score was 82.8 ± 13.0 points, with 55 patients reporting excellent results. No patient scored less than 30 points, which could be deemed as unsatisfying. Meanwhile, on the DASH questionnaire, 6.1% of our patients rated their clinical outcome as unsatisfying, whereas 75.8% rated their outcome as excellent. Postoperative MRI classified 45 patients (83.3%) as either Sugaya type I, II, or III, whereas 9 patients (16.7%) presented a Sugaya type IV consistent with a full-thickness cuff retear. Of these nine patients, five (55.6%) and three (33.3%) reported excellent results for the Constant score and DASH questionnaire, respectively. The Mann-Whitney test reported that the retear group had worse scores than the intact repaired cuff group for pain (8.3 ± 5.0 versus 13.1 ± 3.4), Constant Score (68.8 ± 18.5 versus 83.1 ± 11.6), and DASH (66.2 ± 22.1 versus 44.2 ± 14.9). Still, range of motion (ROM) differences were not significant, except for better forward flexion in the intact group (p < 0.039). CONCLUSIONS: Both groups with intact repaired and retorn cuffs showed improvement in their condition, but unexpectedly, there is no significant correlation between patient satisfaction and rotator cuff integrity. LEVEL OF EVIDENCE: IV.

The mixture of polymethylmethacrylate (PMMA) and ß-tricalciumphospate (ß-TCP) is the most widely used bone graft. Common features of bone cement are the biocompatibility, bioactivity, mechanical stability and ability to fuse with the host's bone tissue. However, there are still few studies that have evaluated these characteristics in vivo. Our study aims to acquire these parameters, using an animal model with functional characteristics similar to those of humans. The analyzed cement is Calcemex®, evaluated both in compact and fluid formulation. The chosen animal models were 5 pigs, treated with femoral and tibial implants of Calcemex® samples. After one year, the pigs were sacrificed and the specimens explanted for morphological, histological, ultrastructural and mechanical evaluations. For both formulations, the investigation highlighted the absence of foreign body reactions in the host, the histological integration with the surrounding tissues and the preservation of mechanical compression resistance.

BACKGROUND: The increase in the incidence of osteoarthritis of the hip (coxarthrosis) in young patients with high functionality requirements and the development of new materials in the last twenty years have resulted in an increase in the number of surgeries involving hip resurfacing procedures. There has also been an increase in associated periprosthetic fractures, which currently occur in 1%-2% of cases. According to the medical literature, fractures of this type can be treated conservatively, using reduction and synthesis or through prosthetic revision. CASE REPORT: Patient aged 69 years who had undergone resurfacing of the right hip ten years previously, who came to our attention as a result of direct contusion trauma with x-ray evidence of a periprosthetic fracture in the subtrochanteric region. We treated the fracture by preserving the prosthesis and performing osteosynthesis using a plate and screws. After two months the synthesis was complicated by breakage of a proximal screw and varus collapse of the fracture. We treated this complication conservatively by adjusting the weight-bearing regime and administering physical and drug therapy. Six months after the fracture, despite the residual varus displacement and the less than stellar x-ray result, the clinical outcome was satisfactory. Discussion and conclusions: Treatment of periprosthetic fractures following hip resurfacing is often technically complex. The major difficulties arise from the presence of prosthetic components and the limited bone stock available. Fractures often affect the neck of the femur and the trochanteric region, and in rare cases there is involvement of the subtrochanteric region. Our review confirms this trend and raises the question as to which method of synthesis is ideal for a fracture pattern so rarely described in the literature.

The autologous lipoaspirate processing allows to obtain a tissue product to be transplanted for regenerative purposes in multiple pathological sites, such as the knee joint affected by osteoarthritic disease. Recently, multiple protocols and devices have been designed for lipoaspirate processing. These protocols and devices do not use enzymatic digestion and respect the principles of the so-called "minimal manipulation in a closed system". In this study, we performed a systematic review of the literature to identify studies in which osteoarthritis was treated by minimally manipulated intra-articular SVF injection and assessment of therapeutic response was reported. All bias scores were analyzed based on the Coleman methodology score modified by Kon et al. [27] and a subsequent linear classification system of articles was proposed. We identified 12 clinical trials in which clinical evaluations were performed inconsistently using different scales of analysis. All studies reported a significant decrease in the patient's symptomatic discomfort, with improvement in joint function and reduction in pain. Most studies do not reach a high-quality level on the linear scale based on the Coleman-Kon scores. Although the treatment of osteoarthritis of the knee with regenerative methods is undoubtedly of interest, being aimed at healing the disease, this study highlights that the trials are numerically limited, and qualitatively not optimal according to the Coleman-Kon score. Reasonably, greater standardization of devices protocols will be desirable in the future. The high clinical potential offered by these methods could be optimized for all patients.

Hallux rigidus (HR) is the clinical manifestation of osteoarthritis of the first metatarsophalangeal (MTP1) joint and affects about 2.5% of people older than 50 years. The condition may significantly impact patients' quality of life, leading to debilitating pain and limited range of motion (ROM). Numerous hypotheses have been postulated about contributing factors to the development of the disease, but with poor proven association. Some types of footwear over others may transmit altered pressure and stress toward the forefoot and this can significantly contribute to development of the condition. The purpose of this review is therefore to analyze the importance of correct footwear and if an incorrect shoe can influence the development and/or worsening of symptoms in patients affected by HR. From the results of the studies, it appears that symptoms improve with rigid-soled low-heeled shoes such as boots and worsen with flat flexible-soled shoes such as sandals and tennis shoes, which should therefore be avoided. Despite this, although incorrect footwear increases symptoms, a direct correlation with the development of the condition has not been detected but rather an improvement in comfort in some types of shoes than in others. In predisposed patients, incorrect footwear is more a way to increase symptoms than a real risk factor for the development of the disease, remaining in a very low risk percentage to be considered indicative.

BACKGROUND: The aim of this paper is to analyze the effectiveness of corticosteroid injections (CI), in combination with or without a local anaesthetic, for Civinini-Morton's Syndrome to determine which protocol could be the most appropriate among conservative treatments. METHODS: All selected articles were screened using a thorough database search of PubMed, EMBASE and SCOPUS to assess their suitability to the research focus. RESULTS: Selection produced 10 articles as full-text, for a total of 590 patients, with a mean follow-up of 14 ± 14.2 (range 3-48) months. Johnson satisfaction scale, resulting from 6 studies, scored 25.6% (range 5-38) and 39.4% (range 15-51.8), respectively completely satisfied and satisfied with minor reservations. Mean VAS, declared in 5 studies, decreased from 70.7 ± 16.5 (range 67-89) to 33.4 ± 7.6 (26-42.5) points (p < 0.01). Most common complication was skin depigmentation in 7 (2.6%) cases. CONCLUSIONS: CI appear to be a safe treatment allowing good results with a very low complications rate. A neuroma of 6.3 mm seems to be the cut-off size; below which CI could have best indications and be considered as an intermediate treatment between shoe modifications and more invasive procedures such as percutaneous alcoholization or surgery. LEVEL OF EVIDENCE: Level II, systematic review.
