RESUMO

(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.

RESUMO

BACKGROUND: Proximal femur fractures have a negative impact on loss of functional autonomy and mortality. OBJECTIVE: The aim of this retrospective study was to evaluate functional autonomy and mortality in a group of older adults with hip fractures managed in an orthogeriatric setting 12 months after discharge and to determine if gender affected outcome. METHODS: In all participants, we assessed clinical history, functional pre-fracture status using activities of daily living (ADL) and in-hospital details. At 12 months after discharge, we evaluated functional status, place of residence, hospital readmissions and mortality. RESULTS: We studied 361 women and 124 men and we observed a significant reduction in the ADL score at 6 months (1.15 ± 1.58/p < 0.001 in women and 1.45 ± 1.66/p < 0.001 in men). One-year mortality (33.1% in men and 14.7% in women) was associated with pre-fracture ADL score and reduction in ADL at 6 months (HR 0.68/95%, CI 0.48-0.97/p < 0.05 and HR 1.70/95%, CI 1.17-2.48/p < 0.01, respectively) in women, and new hospitalisations at 6 months and polypharmacy in men (HR 1.65/95%, CI 1.07-2.56/p < 0.05 and HR 1.40/95%, CI 1.00-1.96/p = 0.05, respectively) in Cox's regression model. DISCUSSION AND CONCLUSIONS: Our study suggests that functional loss in older adults hospitalised for proximal femur fractures is greatest in the first 6 months after discharge, and this increases the risk of death at 1 year. Cumulative mortality at 12 months is higher in men and appears to be related to polypharmacy and new hospital admissions 6 months after discharge.

RESUMO

INTRODUCTION: 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. PATIENTS AND METHODS: 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). RESULTS: Overall survival was significantly better in patients with solitary metastasis or oligometastases than in those with multiple metastases (p <0.0001). Patients treated with resection and prosthesis had significantly better survival than those treated with nailing (p <0.0001). Implant complications requiring surgical revision occurred in 20 patients treated with prostheses, while no complications occurred in patients treated with nailing. DISCUSSION: 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. CONCLUSIONS: 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.

RESUMO

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.

RESUMO

Purpose: The aim of this study is to compare titanium vs carbon fiber intramedullary (IM) nailing in terms of response to radiotherapy, local control of the disease, time of surgery, fluoroscopy exposure, and complications. Methods: From 2015 to 2021, 52 impending or pathologic fractures were treated with IM nailing in 47 patients: 18 males and 29 females with a mean age of 73. Titanium nails were used in 27 cases: femur (17 cases), humerus (8 cases), and tibia (2 cases). Carbon fiber nails were used in 25 cases: femur (17 cases), humerus (7 cases), and tibia (1 case). Results: At a mean follow-up of 8.4 months, most patients died from the disease (63.4%). Fracture healing without osteolysis progression was present in 52% of titanium nailing at a mean time of 6 months and in 53% of carbon fiber nails at a mean time of 4.6 months. No statistically significant difference has been shown in terms of healing (P = 0.5), intraoperative fluoroscopy (P = 0.7), and time of surgery in femoral nailing (P = 0.6), while a significantly lower surgical time for carbon fiber humeral nailing (P = 0.01) was found. Two breakages of carbon fiber femoral nails were observed, and both were treated with revision with modular tumor megaprosthesis. Conclusions: Our results suggest that surgical time and fluoroscopy exposure are not longer for carbon fiber nails compared to titanium ones. Healing seems to be faster in carbon fiber nails. Further clinical studies are needed to clarify the long-term outcomes of these implants.

RESUMO

The treatment of displaced midshaft clavicle fractures (MCFs) is still controversial. The aims of our study were to evaluate clinical and radiological outcomes and complications of patients with displaced MCFs managed nonoperatively and to identify potential predictive factors of worse clinical outcomes. Seventy-five patients with displaced MCFs were enrolled and treated nonoperatively with a figure-of-eight bandage (F8-B). Initial shortening (IS) and displacement (ID) of fragments were radiographically evaluated at the time of diagnosis and immediately after F8-B application by residual shortening (RS) and displacement (RD). The clavicle shortening ratio was evaluated clinically at last follow-up. Functional outcomes were assessed using Constant (CS), q-DASH, DASH work and DASH sport scores. Cosmetic outcomes and rate of complications were evaluated. Good to very good mid-term clinical results were achieved by using the institutional treatment protocol. Multiple regression identified RS as an independent predictor of shoulder function, while RD affects fracture healing. These findings support the efficacy of our institutional protocol and thus could be useful for orthopedic surgeons during the decision-making process.

RESUMO

INTRODUCTION: Treatment of complex proximal humerus fractures (PHFs) in the elderly should provide early mobilization to maintain autonomy and self-care possibility, avoiding further surgery for complications. Nowadays, there is not a gold standard for treatment. Aim of our study was to review our experience with the use of Reverse Total Shoulder Arthroplasty (RTSA) for the treatment of these fractures in the elderly, evaluating complications and functional results. MATERIALS AND METHODS: Ninety-one patients older than 65 were treated with RTSA at our Institute between June 2005 and December 2017: there were 14 males and 77 females, with a mean age of 76 years (range 65-87 years). There were 58 fractures (20 Neer 3, 38 Neer 4) and 33 fracture-dislocations (7 Neer 3, 26 Neer 4). Complications were recorded, and functional outcomes were evaluated using the DASH score and Constant score (CS). RESULTS: Twenty-three complications occurred: 8 cases of scapular notching, 5 neurologic palsies, 4 dislocations, 3 intraoperative diaphyseal fractures, and subclavian artery damage, deep infection, and radiolucent line in one each. No aseptic loosening or breakage was observed. Further surgeries were necessary in 3 cases only, whereas all patients retained their implant at last follow-up. Functional results were satisfactory: mean abduction was 93°, mean flexion was 110°, mean active internal-rotation reached 35°, mean active external-rotation was 25°, mean CS was 54 points and mean DASH score was 45 points. DISCUSSION: Surgical treatment of complex PHFs should be a "one-shot surgery," especially in the elderly, since further surgeries could compromise patient outcomes and survival. Additional surgery due to complications is less frequent after RTSA than other techniques. A stable reconstruction permitting early mobilization is fundamental in the elderly. Usually, a prolonged immobilization is recommended after ORIF, TSA, and hemiarthroplasty to provide a stable fixation, whereas RTSA allows early mobilization. CONCLUSIONS: In elderly with inadequate bone stock and needing early recovery of autonomy in daily activities, RTSA effectively treats complex PHFs. The incidence of complications requiring revision surgery is low and functional results are satisfactory and predictable.

RESUMO

PURPOSE: Modular megaprostheses have widely replaced allografts, as a reconstructive option; however, failures of these devices remain high. Aim of this study was to analyze outcomes, survival of the implants, incidence and types of complications with Mutars modular endoprostheses at long term. METHODS: Between 2000 and 2019, 187 Mutars prostheses were implanted in two dedicated centers: 72 upper limbs and 115 lower limbs reconstructions. Diagnoses included 107 primary malignant bone or soft tissue tumors, 65 metastases, 8 benign bone tumors and 7 non-oncologic cases. Silver-coated prostheses were used in 118/187 (63%) cases. RESULTS: At last follow-up, 76.5% of patients had retained their implant. The overall failure rate was 23.5% at a mean of 1.7 years. There were 22 mechanical failures and 22 non-mechanical failures. The overall implant survival to all types of failure was 68% and 52% at 5 and 10 years, respectively. Infection was the most common mode of failure with an incidence of 6.9%. Implant survival to infection was better for silver-coated implants than for standard implants even if with no significant difference (p = 0.56). Functional results were satisfactory in 97% of patients. CONCLUSIONS: The overall implant survival at long term was satisfactory with Mutars prostheses. The incidence of complications with Mutars prosthesis is in line with the incidence reported in the literature with other types of tumor prosthesis. The most frequent cause of failure was infection with a lower incidence in silver-coated prostheses; silver coating seems to prevent infection in distal femur and proximal tibia. The silver coating seems to be particularly useful in two-stage revisions with a lower incidence of secondary amputation. In higher risk patients, silver-coated prostheses are the preferable choice for the reduction of the reinfection rate. The functional results of Mutars prostheses were excellent or good in most of cases. The current paper is design to enhance the literature on megaprosthesis in tumor surgery, proven that this system is one of the most used all over the word and one of the best performing.

RESUMO

BACKGROUND: Double ipsilateral femoral fractures account for 1-9% of femoral fractures. There is no clear advantage between single or double implant osteosynthesis. We present a series of patients with double ipsilateral femoral fractures, to address the challenges in treatment, namely the implants for osteosynthesis and complications of treatment. MATERIALS AND METHODS: We retrospectively studied 16 patients (7 men, 9 women; mean age, 51 years) treated from January 2015 to December 2018. Motor vehicle accidents were the leading cause of injury. Types of fractures were pertrochanteric and shaft (6), pertrochanteric and distal (2), double shaft (3), neck and shaft (2), neck and distal (1), shaft and distal (1), and triple fracture including a pertrochanteric, shaft and distal (1). In five patients, two different implants were used (plate and screws, cannulated hip screws, femoral nail), whereas in 11 patients a long femoral nail was used. RESULTS: Fourteen patients experienced union at a mean of 3 months (2-6 months). Two patients experienced nonunion: both had plate and screws osteosynthesis. One patient died 15 days after admission from polytrauma and another patient experienced central venous catheter thrombosis and pneumonia. Surgical complications (2 patients) included a thigh skin necrosis, and external fixator pin tract infection/infected non-union. Weight-bearing was delayed in all patients; full weight-bearing was allowed in 11 patients at 4 months postoperatively, and in four patients at 5 months. CONCLUSION: Due to the rarity and the difficulty of standardization of double ipsilateral femoral fractures, there is variable information on the optimal osteosynthesis of the fractures and the outcome of the patients. It seems that closed reduction and long hip nailing is the treatment of choice, with few complications.

RESUMO

We report our clinical experience of a 1 year and 10 month child with traumatic anterior shoulder dislocation who underwent non-operative reduction and Desault's bandage immobilization for 10 days. No associated fractures were found and after bandage removal, full ROM of the shoulder was immediately assessed. Further research is needed to unified guideline of treatment and the time of immobilization for this type of injury in pediatric population.

RESUMO

Background and Objectives. Wide surgical resection is a relevant factor for local control in sarcomas. Plastic surgery is mandatory in demanding reconstructions. We analyzed patients treated by a multidisciplinary team to evaluate indications and surgical approaches, complications and therapeutic/functional outcomes. Methods. We analyzed 161 patients (86 males (53%), mean age 56 years) from 2006 to 2017. Patients were treated for their primary tumor (120, 75.5%) or after unplanned excision/recurrence (41, 25.5%). Sites included lower limbs (36.6%), upper limbs (19.2%), head/neck (21.1%), trunk (14.9%) and pelvis (8.1%). Orthoplasty has been considered for flaps (54), skin grafts (42), wide excisions (40) and other procedures (25). Results. At a mean follow-up of 5.3 years (range 2-10.5), patients continuously showed no evidence of disease (NED) in 130 cases (80.7%), were alive with disease (AWD) in 10 cases (6.2%) and were dead with disease (DWD) in 21 cases (13.0%). Overall, 62 patients (38.5%) developed a complication (56 minor (90.3%) and 6 major (9.7%)). Flap loss occurred in 5/48 patients (10.4%). The mean Musculoskeletal Tumor Society (MSTS) and Toronto Extremity Salvage Score (TESS) was 74.8 ± 14 and 79.1 ± 13, respectively. Conclusions. Orthoplasty is a combined approach effective in management of sarcoma patients, maximizing adequate surgical resection, limb salvaging and functional recovery. One-stage reconstructions are technically feasible and are not associated with increased risk of complications.

RESUMO

Tumor seeding after intra-abdominal and head and neck cancer surgery is a well-known entity. The risk of disseminating cancerous cells during surgery is also described for soft-tissue sarcoma of the extremities. Nonetheless, after reconstructive surgery using flaps, the risk of recurrence at the donor site is extremely rare. Up to this date, the literature describes only three cases, but none of them reported a translocated recurrence after a reconstruction with a propeller flap. Here, we report a case of high-grade pleomorphic sarcoma of the knee, which recurred at the proximal edge of a propeller flap 28 months after the first excision surgery. The reasons for such local recurrences are not clear and previous works have advocated different theories: direct contamination by tumor cells, physical manipulation of the tumor and creation of surgical wounds with tumor supportive properties. Although these particular cases of recurrence are exceedingly rare, certain precautionary meticulous surgical techniques and a thorough preoperative planning are pivotal to avoid the contamination of "clean" areas during the first excision surgery.

RESUMO

Total hip arthroplasty (THA) with metal-on-metal (MoM) bearings have shown problems of biocompatibility linked to metal ion release at the local level causing an adverse reaction to metal debris (ARMD) and at a systemic level. The aim of this study was to evaluate clinical and radiological outcomes, and metal ion concentrations in the blood and urine of patients who underwent THA with the LIMA Met-Met hip system. Patients with ceramic-on-ceramic (CoC) bearings were included as a control group. In this study, 68 patients were enrolled: 34 with MoM THAs and 34 with CoC THAs. Patients were evaluated clinically (Harris Hip Score, SF-36) and radiologically at a median of 7.4 years after surgery. Whole blood and urinary cobalt and chromium levels were also assessed. Both types of implants were comparable in terms of clinical and functional results. Ion levels were significantly higher in the MoM group compared with CoC group 7 years after surgery. No correlations were found between metal ion levels and patient demographics, functional and radiological outcomes, and prosthesis features. Patient monitoring is thus advised to establish if prosthesis revision is necessary, especially in the case of MoM THA.

RESUMO

As there are no clear and unique radiographic predictors of healing disturbances for acute midshaft clavicle fractures, their treatment is still controversial. The aim of the study was to evaluate in midshaft clavicle fractures treated nonoperatively if fracture type (FT), shortening, and displacement, assessed before and after figure-of-eight bandage (F8-B) application, could be considered prognostic factors of delayed union and nonunion. One hundred twenty-two adult patients presenting a closed displaced midshaft clavicle fracture, managed nonoperatively with an F8-B, were enrolled. FT, initial shortening (IS), and initial displacement (ID) were radiographically evaluated at diagnosis, and both residual shortening (RS) and displacement (RD) were measured after F8-B application. The patients were followed up 1, 3, 6, and 12 months post-injury. Multivariate statistical analysis was performed. RD should be considered as radiological predictor of sequelae. Further, an RD equal to 104% of clavicle width was identified as an optimal cut-off point to distinguish between healed and unhealed fractures, and 140% between delayed union and nonunion. Our data pointed out the effectiveness of the F8-B in reducing fracture fragments and restoring clavicular length. In midshaft clavicle fractures of adults, fracture comminution and clavicular shortening did not influence bone healing. On the contrary, RD has been shown as the most likely predictor of both delayed union and nonunion.

RESUMO

Myeloid-derived suppressor cells (MDSCs) are a heterogeneous population of immunosuppressive cells developing from myeloid progenitors, which are enriched in pathological conditions such as cancer, and are known to inhibit the functions of effector T cells. During aging, several changes occur both at the adaptive and innate immune system level, in a process defined as immunoscenescence. In particular, the low-grade inflammation state observed in the elderly appears to affect hematopoiesis. We previously demonstrated that the combination of GM-CSF and G-CSF drives the in vitro generation of bone marrow-derived MDSCs (BM-MDSCs) from precursors present in human bone marrow aspirates of healthy donors, and that these cells are endowed with a strong immune suppressive ability, resembling that of cancer-associated MDSCs. In the present work we investigated BM-MDSCs induction and functional ability in a cohort of pediatric versus elderly donors. To this aim, we analyzed the differences in maturation stages and ability to suppress T cell proliferation. We found that the ex vivo distribution of myeloid progenitors is similar between pediatric and elderly individuals, whereas after cytokine treatment a significant reduction in the more immature compartment is observed in the elderly. Despite the decreased frequency, BM-MDSCs maintain their suppressive capacity in aged donors. Taken together, these results indicate that in vitro induction of MDSCs from the BM is reduced with aging and opens new hypotheses on the role of age-related processes in myelopoiesis.

RESUMO

Osteoarthritis (OA) is one of the most common joint disorders. Evidence suggests that the infrapatellar fat pad (IFP) is directly involved in OA pathology. However, a comparison between OA versus non-OA IFP is still missing. Thus, the aim of this study was to compare IFP molecular, adipocytes and extracellular matrix characteristics of patients affected by OA, and patients undergoing anterior cruciate ligament (ACL) reconstruction. We hypothesized that not only inflammation but also changes in adipocytes and extracellular matrix (ECM) composition might be involved in OA pathogenesis. Fifty-three patients were enrolled. IFP biopsies were obtained, evaluating: (a) lymphocytic infiltration and vascularization; (b) adipocytes area and number; (c) adipo-cytokines and extracellular matrix gene expression levels; (d) IL-6 and VEGF protein production; (e) collagen fibers distribution. OA IFP was more inflamed and vascularized compared to ACL IFP. OA IFP adipocytes were larger and numerically lower (1.3-fold) than ACL IFP adipocytes. An increase of gene expression of typical white adipose tissue genes was observed in OA compared to ACL IFP. Collagen-types distribution was different in the OA IFP group compared to controls, possibly explaining the change of the biomechanical characteristics found in OA IFP. Statistical linear models revealed that the adipocyte area correlated with BMI in the OA group. In conclusion, inflammation and fibrotic changes of OA IFP could represent novel therapeutic targets to counteract OA.

RESUMO

BACKGROUND/AIM: Chondrosarcomas (CS) of the chest wall are rare, but present an aggressive biological behavior compared to CS of the extremities. The aims of the present study were to determine factors associated with oncological outcomes as well as complications. PATIENTS AND METHODS: We retrospectively analyzed 53 patients (42 primary, 11 recurrent tumors). In total, 39 central CS, 10 peripheral CS, 3 dedifferentiated CS and 1 mesenchymal CS were included. The ribs were most commonly affected (68%). Overall survival and disease-free survival were estimated with Kaplan-Meier analyses and compared with log-rank test. RESULTS: Mean follow-up was 7 years. Negative margins were achieved in 87% of patients. Thirty patients (57%) remained continuously disease-free (NED), three (5%) NED after treatment of relapse, seven (13%) were alive with disease, twelve (23%) were dead with disease and one of other cause. The 10-year survival rate was 81% and 45% in primary and recurrent tumors, respectively. Survival was significantly affected by tumor stage (p<0.001), local recurrence (p=0.025) and metastases (p=0.002). Six complications (16%) were observed. CONCLUSION: The outcome is rather poor, especially in patients with local recurrence. Presumably due to a high biological aggressiveness, a stricter definition of surgical margins should be considered for this location.

RESUMO

BACKGROUND: hip fracture has negative consequences for elderly people. Alternative models of care, with respect to traditional model, were developed to minimize complications and improve functional outcomes. The interdisciplinary model in orthopaedic wards has less evidence of efficacy compared to orthogeriatric units. OBJECTIVE: to compare the efficacy (in-hospital outcomes, mortality, functional status at 6 months after discharge) of an interdisciplinary pathway, based on comprehensive geriatric assessment, compared to a traditional model of care, in hip-fractured elderly patients. DESIGN: prospective study with retrospective control group conducted in a first-level trauma center Orthopaedic Unit. SUBJECTS: 97 patients treated with the traditional model and 127 with an interdisciplinary pathway (mean age 83.9 ±â€¯7.4 vs 84 ±â€¯6.7 years, p = 0.89). METHODS: in all participants we assessed: clinical history, functional pre-fracture status utilising Activities of Daily Living (ADL), in-hospital details. At 6 months after discharge, we evaluated functional status, place of residence, hospital readmissions, mortality. RESULTS: during hospital stay, significant differences emerged in mortality and in external visits. A higher proportion of patients of the orthogeriatric group lived alone at home at 6 months and showed a lower functional decline. Comprehensive geriatric assessment was associated with the ADL score (partial R2: 0.08, p < 0.001) and with a higher probability of independent walking ability ([OR] 3.89 95% [CI] 1.73-8.74, p = 0.001). CONCLUSIONS: an interdisciplinary pathway in hip-fractured elderly patients, could reduce in-hospital mortality, improve functional recovery and increase the probability of living alone at home, at 6 months.
