RESUMEN
INTRODUCTION: Wide Surgery is the reference treatment for malignant and aggressive benign primary bone tumors in the spine. When located in the lumbar spine, En-Bloc Spondylectomy (EBS) remains a complex challenge. Moreover, surgery is complicated by the presence of the diaphragm in the thoracolumbar junction and the hinderance of the iliac wings at the lumbosacral levels. Therefore, EBS in the lumbar spine frequently requires combined approaches. The purpose of this study is to describe clinical presentation, tumor characteristics and results of a series of 47 consecutive patients affected by malignant primary bone tumors of the lumbar spine who underwent EBS. MATERIALS AND METHODS: 47 patients were reviewed. Complications were distinguished in early and late whether they occurred before or after 30 days from surgery. Overall survival (OS), disease-free survival (DFS) and local recurrence-free survival (LRFS) were calculated by the Kaplan-Meier product-limit method from surgery until relapse or death. RESULTS: 27 patients presented to observation after a first intralesional approach in a non-specialized center. Chordoma was the most represented histotype. Vertebrectomies were: 23 one-level, 10 two-level, 12 three-level and 2 four-level. Reconstructions were always carried out with screws and rods. The main postoperative complication was blood loss, while hardware failure was the main long-term complication. The 5-year LRFS was 75.5%, the 5-year DFS was 54.3%, and 5-year OS was 63.6%. CONCLUSIONS: The surgical margin obtained during the index surgery was statistically associated with Local Recurrence, DFS and OS, underlining the importance of treating patients in reference centers.

BACKGROUND: En bloc resection remains the cornerstone treatment for malignant bone tumors affecting the spine. The thoracic spine poses unique challenges because of the proximity of crucial structures. This study assesses outcomes of patients who underwent en bloc spondylectomy for malignant bone tumors at the thoracic level. METHODS: We retrospectively reviewed 85 cases of primary and secondary bone tumors in the thoracic spine, undergoing en bloc spondylectomy from 1996 to 2016. Evaluation encompassed clinical presentation, tumor characteristics, surgical outcomes, complications, survival, and recurrence. RESULTS: Of 85 patients, 40 presented directly, whereas 45 had undergone previous intralesional surgery. Chondrosarcoma and chordoma comprised the most prevalent primary histologic types; thyroid and kidney carcinomas were the most frequent secondary tumors. Pain was reported in 75 patients at diagnosis. Margins were adequate in 54 cases and intralesional in 31. Immediate postoperative deaths amounted to 4. Major complications included substantial blood loss, neurologic deterioration, and paraplegia. The 5-year local recurrence-free survival was 58.7%, significantly influenced by the surgical margin: patients with wide margins experienced a 5-year local recurrence-free survival of 85.7%, whereas those with marginal and intralesional margins had rates of 56.7% and 45.6%, respectively; overall recurrence was 22.3%, with no notable disparities between previously treated and untreated patients. The 5-year overall survival was 63.2% and 56.2% for primary and secondary tumors, respectively. The overall survival was not significantly influenced by surgical margins. CONCLUSIONS: Managing malignant thoracic bone tumors poses significant challenges. This study underscores the criticality of achieving adequate margins, particularly after previous intralesional approaches.

Wide resection is currently considered the mainstay treatment for primary bone tumors. When the tumor is located in anatomically complex segments, 3D-Printed Titanium Custom-Made Prostheses (3DPTCMP) are possible reconstructive solutions. The aim of the present paper is to analyze indications, results and complications of a series of 14 patients who underwent pelvis reconstruction with 3DPTCMP after tumor removal from January 2015 to December 2019. Chondrosarcoma was the main histology; indications were tumors located in the acetabular area without enough residual bone to support a cup with an iliac stem, and tumors located near the sacrum-iliac joint. The margins were wide in 12 cases, and marginal and intralesional in one case each. In three cases, resection also included the sacrum-iliac joint, so a spine stabilization was performed and linked to the pelvic prosthesis; The average MSTS score was 46.3%; the 5-year local recurrence-free survival was 85.7%. Wound dehiscences were the main complication, resolved with multiple debridements; nevertheless, prosthesis removal was necessary in one case. Currently, the 3DPTCMP is an effective resource for reconstruction after resection of tumors located in the pelvis. Further studies are necessary to value long-term results; more strategies are necessary to try to reduce the infection rate and improve osteointegration.
RESUMEN
BACKGROUND: En bloc surgery is the mainstay treatment for primary malignant bone tumors, as well as in the cervical spine. Unfortunately, literature on the topic is limited to case reports and small series. METHODS: We reviewed all patients affected by primary cervical spine bone tumors treated with en bloc surgeries from 1996 to 2016 and identified 30 eligible cases. We evaluated the clinical presentation and tumor characteristics and reported surgical results, complications, recurrence, and survival rates. RESULTS: Only 17 of 30 patients had not been previously treated at presentation. Osteosarcoma and chordoma were the most frequent tumors, and pain was reported in all cases. En bloc spondylectomy, hemispondylectomy, and posterior arch en bloc resection were performed in 16, 12, and 2 patients, respectively. The obtained margin was adequate (wide and marginal) in 60% of cases and intralesional in the remaining cases. Two deaths occurred in the immediate postoperative period. Neurological deterioration, dural tear, and dysphagia were the most frequent complications. The 5-year local recurrence-free survival was 70.4%. The recurrence rate was 38.5% and 11.7% in previously and non-previously treated patients, respectively (χ2: 2.94; P = 0.086). Overall survival at 5 years was 58% and 47% for all series and malignant tumors, respectively. CONCLUSION: Primary cervical spine bone tumors present a difficult approach. Findings suggest that patients treated with en bloc surgery show recurrence and survival rates comparable to the same tumors located in the thoracolumbar spine.

PURPOSE: Review a series of 22 patients below the age of 16 affected by primary bone tumors of the spine who underwent en bloc resection, and describe the clinical presentation, tumor characteristics, results and complications associated with the surgical treatment, underlining the specific issues related to a younger age. METHODS: We performed a review of all patients < 16 years old affected by primary bone tumors of the spine, surgically treated with en bloc resection from 1996 to 2016. Clinical and radiological characteristics, therapy, complications and survival are reported. RESULTS: Only 12/22 cases had not been previously treated. 22.7% experienced at least one early complication; 18.2% and 4.1% experienced at least 2 and ≥ 3 early complications, respectively; 40.9% experienced at least one late complication, often related to hardware failure (27.3%); 18.2% and 4.5% at least 2 and ≥ 3 late complications. No early nor late complications were experienced in 12 out of 22 patients (54.54%). The overall survival and the local recurrence-free survival at 5 years were, respectively, 79.5% and 74.8%; considering only the patients with high-grade tumors, they were 70.9% and 65.5%, respectively. At 77.3 months of median follow-up, 17 patients are still alive, 16 of whom without any evidence of disease and 1 with evidence of local and systemic disease; four patients died with evidence of local disease and one with distant metastases but no local recurrence. CONCLUSIONS: Young people with primary malignant or locally aggressive bone tumors of the spine should be treated in specialized centers, and wide surgery should be performed. The most frequent problems are related to reconstruction in a growing spine and subsequent hardware failure that make later surgeries necessary.

PURPOSE: Knowledge about quality of life (QOL), pain, and psychological factors in patients with primary tumors of the spine is limited, but is important in planning rehabilitation after surgery. Aims of this study were to assess the preoperative levels and improvement after surgery of these factors, and to identify the predictors of postoperative pain and QOL. METHODS: Patients with primary tumors undergoing spine surgery were matched for sex and age with patients with metastatic tumors. QOL was measured at baseline and three months after surgery with the physical (PCS) and mental (MCS) components SF-12 subscales, pain intensity with a numeric rating scale (NRS), depression with the Beck Depression Inventory (BDI). Preoperative SF-12, NRS, and BDI levels and differences in follow-up improvement in SF-12 and NRS were compared across samples. LASSO regressions were performed to find predictors of follow-up SF-12 and NRS. RESULTS: Patients with primary tumors showed better PCS and NRS, and similar BDI and MCS than patients with metastatic tumors. At follow-up, they showed stronger improvement in the MCS and no improvement in the PCS. All QOL scores were below those of the general population. Follow-up PCS was predicted by baseline PCS and BDI; MCS by baseline MCS; pain intensity by baseline pain intensity and BDI. CONCLUSION: Patients with primary tumors of the spine suffer from moderate levels of physical and mental impairment. Depression influences surgical outcomes.

PURPOSE: To review a series of patients > 60 years affected by primary spine bone tumors, who have undergone surgery, and to describe their clinical presentation, results and complications associated with surgical treatment. METHODS: A review of all patients > 60 years affected by primary spine bone tumor surgically treated with en bloc spondylectomy from 1993 to 2015 was performed. Thirty-seven cases were identified, and clinical and radiological characteristics, therapy, complications and survival were evaluated. RESULTS: Only 14/37 cases were not previously treated. Complications were quite frequent: 64% of patients experienced almost one early complication; 48% and 27% experienced 2 and ≥ 3 early complications, respectively; 37% of patients experienced almost one late complication; and 10% and 8% experienced 2 and ≥ 3 late complications, respectively. Massive blood loss and dural tear were the more frequent surgical complications; no deaths were reported during surgeries; one patient died during the first postoperative day due to hemorrhage and cardiac complications, one during the third postoperative day for the same cause despite of a savage surgery, and another one died at 7 days from index surgery due to myocardial infarction. The 5-year disease-related survival and global survival were 62.8% and 52.1%, respectively. Nineteen patients are still alive, 15 of whom without any evidence of disease. CONCLUSIONS: Primary malignant or locally aggressive bone tumors of the spine should be treated with wide surgery also in the older age, although the complications rate and the risk of patient survival can be considered high.

OBJECTIVES: Few studies have evaluated surgical options in the treatment of cervical metastatic disease. The aim of this study is to report the surgical outcomes of patients treated with the posterior-only approach for metastatic cervical disease. METHODS: In this retrospective analysis, all cases treated in our institution from 2009 to 2017 were reviewed. Six (20%) patients had intracompartimental lesions (Tomita 1-3), whereas 24 (80%) patients had extracompartimental lesions (Tomita 4-7), with extensive anterior column involvement. All patients were surgically treated with laminectomy and posterior stabilization. Pain and neurologic function were evaluated before and after surgery. RESULTS: Thirty patients were included (15 female, 15 male), with a mean age of 60.6 ± 11.56 years (range 35-82 years). Lesions were located in 7 patients (23.3%) in the upper cervical spine and in 14 patients (46.6%) and in 9 patients (30,1%) in the mid-cervical and in the cervicothoracic junction, respectively. At a mean follow up of 13.7 ± 14.8 months, 15 (50%) patients died from their disease. Pain decreased in all patients after surgery, (preoperative NRS 5.57 ± 1.81 postoperative Numeric Rating Scale of 2.1 ± 1.0, P < 0.00001). Two patients (6.7%) had significant neurologic worsening after surgery. Two (6.9%) patients had surgical-site infection that required reintervention. No mechanical failures were observed. CONCLUSIONS: In our series, posterior-only fixation provided postoperative pain relief and achieve spinal stability, ultimately improving the quality of life. In conclusion, posterior-approach decompression and stabilization is a safe and feasible procedure in patients with neurologic or mechanical instability for cervical spine metastasis.

PURPOSE: To assess the diagnostic performance of mean apparent diffusion coefficient (mADC) in differentiating benign from malignant bone spine tumors, using histology as a reference standard. Conventional magnetic resonance imaging (MRI) sequences have good reliability in evaluating spinal bone tumors, although some features of benign and malignant cancers may overlap, making the differential diagnosis challenging. MATERIALS AND METHODS: In all, 116 patients (62 males, 54 females; mean age 59.5 ± 14.1) with biopsy-proven spinal bone tumors were studied. Field strength/sequences: 1.5T MR system; T1 -weighted turbo spin-echo (repetition time / echo time [TR/TE], 500/13 msec; number of excitations [NEX], 2; slice thickness, 4 mm), T2 -weighted turbo spin-echo (TR/TE, 4100/102 msec; NEX, 2; slice thickness, 4 mm), short tau inversion recovery (TR/TE, 4800/89 msec; NEX, 2; slice thickness, 4 mm, IT, 140 msec), axial spin-echo echo-planar diffusion-weighted imaging (DWI) (TR/TE 5200/72 msec; slice thickness 5 mm; field of view, 300; interslice gap, 1.5 mm; NEX, 6; echo-planar imaging factor, 96; no parallel imaging) with b-values of 0 and 1000 s/mm², and 3D fat-suppressed T1 -weighted gradient-recalled-echo (TR/TE, 500/13 msec; slice thickness, 4 mm) after administration of 0.2 ml/kg body weight gadolinum-diethylenetriamine pentaacetic acid. Two readers manually drew regions of interest on the solid portion of the lesion (hyperintense on T2 -weighted images, hypointense on T1 -weighted images, and enhanced after gadolinium administration on fat-suppressed T1 -weighted images) to calculate mADC. Histology was used as the reference standard. Tumors were classified into malignant primary tumors (MPT), bone metastases (BM), or benign primary tumors (BPT). Statistical tests: Nonnormality of distribution was tested with the Shapiro-Wilk test. The Kruskal-Wallis and Mann-Whitney U-test with Bonferroni correction were used. Sensitivity and specificity of the mADC values for BM, MPT, and BPT were calculated. Approximate receiver operating characteristic curves were created. Interobserver reproducibility was evaluated using the intraclass correlation coefficient (ICC). RESULTS: The mADC values of MPT (n = 35), BM (n = 65), and BPT (n = 16) were 1.00 ± 0.32 (0.59-2.10) × 10-3 mm2 /s, 1.02 ± 0.25 (0.73-1.96) × 10-3 mm2 /s, 1.31 ± 0.36 (0.83-2.14) × 10-3 mm2 /s, respectively. The mADC was significantly different between BPT and all malignant lesions (BM+MPT) (P < 0.001), BM and BPT (P = 0.008), and MPT and BPT (P = 0.008). No difference was found between BM and MPT (P = 0.999). An mADC threshold of 0.952 × 10-3 mm2 /s yielded 81.3% sensitivity, 55.0% specificity. Accuracy was 76% (95% confidence interval [CI] = 63.9%-88.1%). Interobserver reproducibility was almost perfect (ICC = 0.916; 95% CI = 0.879-0.942). CONCLUSION: DWI with mADC quantification is a reproducible tool to differentiate benign from malignant solid tumors with 76% accuracy. The mADC values of BPT were statistically higher than that of malignant tumors. However, the large overlap between cases may make mADC not helpful in a specific patient.

PURPOSE: Because of the improvement of medical therapy and the corresponding increase in life expectancy, orthopaedic surgeons are obliged to perform more wide resections rather than intramedullary stabilization nailing for patients affected by tumours of the hip compared to the past. Wide resection often causes joint instability, so prosthetic reconstruction presents a higher risk of dislocation than in primary osteoarthritis cases. The aim of the present paper is to classify the indications for the dual mobility cup (DMC) hip prosthesis based on the anatomic structures involved in the disease and to analyse the rationale to reduce the risk of dislocation. METHODS: Indications were analyzed and classified based on all the cases in which the DMC prosthesis was used for reconstruction after hip resection in an oncological research hospital. RESULTS: Four classes of indications were identified; for classes I and IV the indication for DMC prosthesis can be considered strong; for classes II and III the indications must be evaluated considering the specific case, based on life expectancy, performance status, presence of osteoarthritis, and availability of adjuvant local therapies. When the DMC prosthesis is indicated, the cup should always be cemented, either alone or with augmentation techniques, to decrease the risk of mobilization due to local disease progression. CONCLUSIONS: DMC can be a valid alternative in reconstruction of the hip after tumor removal; nevertheless, prospective, randomized studies are necessary to verify the real dislocation rate based on the entity of resection.

BACKGROUND: The mainstay treatment of primary malignant bone tumors is wide surgery in the spine. Unfortunately, most cases undergo the first approach in a nonspecialized center; this often means adopting an inappropriate approach with contamination, which consistently decreases the effectiveness of a second surgery. The aim of the present paper is to evaluate recurrence and survival rates after en-bloc resection. METHODS: All patients underwent wide resection by the senior author from January 1997 to December 2013 after the first inappropriate approach was reviewed. Fifty-six patients were included in the present evaluation. Epidemiologic and clinical characteristics, surgeries, early and late complications, and survival rate were reported. RESULTS: The margin obtained was wide, marginal, and intralesional in 9, 28, and 19 cases, respectively. The complication rates were 55.4% and 44.6% for early and late complications, respectively. Most (73.2%) of the patients had complications. The survival rate is 82.1% at 1 year and then decreases 10% each year until 42.1% at 5 years from surgeries. No statistically significant correlation was found between margin and local recurrence and survival. CONCLUSION: In our series, the first inappropriate approach had already compromised patient prognosis, so in case of suspicious primary spine tumor, the patient had to be referred to a specialized center. The margin obtained during salvage surgery does not appear to influence recurrence and survival, probably because it is already compromised by the first surgery. More prospective studies are necessary to confirm our data and verify the impact of the margin obtained during salvage surgery on patients' survival.

BACKGROUND: Over the years, en bloc spondylectomy has proven its efficacy in controlling spinal tumors and improving survival rates. However, there are few reports of large series that critically evaluate the results of multilevel en bloc spondylectomies for spinal neoplasms. QUESTIONS/PURPOSES: Using data from a large spine tumor center, we answered the following questions: (1) Does multilevel total en bloc spondylectomy result in acceptable function, survival rates, and local control in spinal neoplasms? (2) Is reconstruction after this procedure feasible? (3) What complications are associated with this procedure? (4) is it possible to achieve adequate surgical margins with this procedure? METHODS: We retrospectively investigated 38 patients undergoing multilevel total en bloc spondylectomy by a single surgeon (AL) from 1994 to 2011. Indications for this procedure were primary spinal sarcomas, solitary metastases, and aggressive primary benign tumors involving multiple segments of the thoracic or lumbar spine. Patients had to be medically fit and have no visceral metastases. Analysis was by chart and radiographic review. Margin quality was classified into intralesional, marginal, and wide. Radiographs, MR images, and CT scans were studied for local recurrence. Graft healing and instrumentation failures at subsequent followup were assessed. Complications were divided into major or minor and further classified as intraoperative and early and late postoperative. We evaluated the oncologic status using cumulative disease-specific and metastases-free survival analysis. Minimum followup was 24 months (mean, 39 months; range, 24-124 months). RESULTS: Of the 38 patients, 34 (89%) were alive and walking without support at final followup. Thirty-one (81%) had no evidence of disease. Two patients died postoperatively and another two died of systemic disease (without local recurrence). Only three patients (8%) had a local recurrence. There were 14 major complications and 22 minor complications in 25 patients (65%). Only one patient required revision of implants secondary to mechanical failure. Two cases of cage subsidence were noted but had no clinical significance. Wide margins were achieved in nine patients (23%), marginal in 25 (66%), and intralesional in four (11%). CONCLUSIONS: In patients with multisegmental spinal tumors, oncologic resections were achieved by multilevel en bloc spondylectomy and led to an acceptable survival rate with reasonable local control. Multilevel en bloc surgery was associated with a high complication rate; however, most patients recovered from their complications. Although the surgical procedure is challenging, our encouraging mid-term results clearly favor and validate this technique. LEVEL OF EVIDENCE: Level IV, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

PURPOSE: To review a series of ten cases with epithelioid hemangioendothelioma of the spine, that have undergone surgery to describe clinical presentation, results and complications associated with surgical treatment; a review of literature reporting the main characteristics of the cases already published has been reported. METHODS: A review of patients affected by epithelioid hemangioendothelioma surgically treated by the senior author from 1995 to 2012 was carried out. Ten cases were identified and clinical and radiological characteristics, therapy, complications and survival were valued. RESULTS: Wide margin was achieved in two out of ten cases, marginal margin in seven and intralesional margin in one case. Average intraoperative blood loss was about 2,800 ml. Reported complications were one case of cord injury, one of dural tear, two cases of massive blood loss, a case of reconstruction failure, a wound dehiscence with deep infection, a pneumonia episode and a deep vein thrombosis with pulmonary embolism. Average follow-up was 84.4 months. Two local recurrences, after 32 and 37 months and two deaths for metastasis, after 14 and 36 months, were reported. Although several chemotherapy protocols are available for the treatment of EH of soft tissue, they are not relevant for the bone. CONCLUSIONS: Wide surgery is probably associated with a better prognosis. Indeed most deaths and local recurrences reported in literature happened after intralesional surgery or chemotherapy/RT alone. The presenting study suggests that the best approach to achieve long-term local control and a major survival could be wide surgery, nevertheless more cases series are necessary to verify survival rate.

The acute rupture of the tibialis posterior (TP) tendon, compared to an acute rupture of the Achilles tendon, is a quite uncommon disease to be diagnosed in the emergency department setting. In most cases symptoms related to a TP dysfunction, like weakness, pain along the course of the tendon, swelling in the region of the medial malleolus, and the partial or complete loss of the medial arch with a flatfoot deformity precede the complete rupture of the tendon. In this case report, we describe an acute rupture of the TP tendon following a pronation-external rotation injury of the ankle with no association of a medial malleolus fracture and with no history of a prior flatfoot deformity or symptoms.

PURPOSE: The purpose of this study was to translate the Foot Function Index (FFI) into Italian, to perform a cross-cultural adaptation and to evaluate the psychometric properties of the Italian version of FFI. METHODS: The Italian FFI was developed according to the recommended forward/backward translation protocol and evaluated in patients with foot and ankle diseases. Feasibility, reliability [intraclass correlation coefficient (ICC)], internal consistency [Cronbach's alpha (CA)], construct validity (correlation with the SF-36 and a visual analogue scale (VAS) assessing for pain), responsiveness to surgery were assessed. The standardized effect size and standardized response mean were also evaluated. RESULTS: A total of 89 patients were recruited (mean age 51.8 ± 13.9 years, range 21-83). The Italian version of the FFI consisted in 18 items separated into a pain and disability subscales. CA value was 0.95 for both the subscales. The reproducibility was good with an ICC of 0.94 and 0.91 for pain and disability subscales, respectively. A strong correlation was found between the FFI and the scales of the SF-36 and the VAS with related content, particularly in the areas of physical function and pain was observed indicating good construct validity. After surgery, the mean FFI improved from 55.9 ± 24.8 to 32.4 ± 26.3 for the pain subscale and from 48.8 ± 28.8 to 24.9 ± 23.7 for the disability subscale (P < 0.01). CONCLUSIONS: The Italian version of the FFI showed satisfactory psychometric properties in Italian patients with foot and ankle diseases. Further testing in different and larger samples is required in order to ensure the validity and reliability of this score.
