Cardiovasc Intervent Radiol 2024:10.1007/s00270-024-03746-5. [PMID: 38782766 DOI: 10.1007/s00270-024-03746-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Accepted: 04/25/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE To assess effectiveness on pain, quality of life and late adverse events of percutaneous fixation with internal cemented screw (FICS) among patients with iliac lytic bone metastases with or without pathological fractures. MATERIALS AND METHODS This retrospective exploratory study analyzed FICS procedures on iliac osteolytic bone lesions with and without pathological fracture performed from July 2019 to January 2022 in one tertiary level university hospital. The procedure were performed under general anesthesia, and were CT and fluoroscopically guided. Numerical Pain Rate Score (NPRS), mean EuroQol visual analogue scale (EQ VAS), morphine consumption, walking ability, walking perimeter and presence of walking aids and the appearance of complications were evaluated. RESULTS Nineteen procedures among 18 patients were carried out with a mean follow up time of 243.3 ± 243.2 days. The mean of the maximum NPRS decreased from 8.4 ± 1.3 to 2.2 ± 3.1 at 1 month (p < 0.01) and remained between 1.3 and 4.1 during a follow-up consultation period of 3-24 months. The mean EQ VAS rose from 42.0 ± 12.5 to 57.3 ± 13.9 at 1 month (p < 0.01) follow-up and remained between 55.8 and 62.5 thereafter. No patient scores returned to pre-procedure levels during follow-up. Mean morphine use decreased from 111.1 ± 118.1 to 57.8 ± 70.3 mg/d at 1 month (p > 0.05) follow-up. No late adverse events were reported. CONCLUSION Percutaneous FICS is a safe procedure with fast and long-standing effect on pain, mobility and quality of life. It can be used as a complement to the known analgesic therapeutic arsenal for bone metastases.

[PMID: 38453715 DOI: 10.1007/s00234-024-03325-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 02/24/2024] [Indexed: 03/09/2024]
Abstract
PURPOSE To assess the feasibility and technical accuracy of performing pedicular screw placement combined with vertebroplasty in the radiological setting. METHODS Patients who underwent combined vertebroplasty and pedicle screw insertion under combined computed tomography and fluoroscopic guidance in 4 interventional radiology centers from 2018 to 2023 were retrospectively assessed. Patient demographics, vertebral lesion type, and procedural data were analyzed. Strict intra-pedicular screw positioning was considered as technical success. Pain score was assessed according to the Visual Analogue Scale before the procedure and in the 1-month follow-up consultation. RESULTS Fifty-seven patients (38 men and 19 women) with a mean age of 72.8 (SD = 11.4) years underwent a vertebroplasty associated with pedicular screw insertion for the treatment of traumatic fractures (29 patients) and neoplastic disease (28 patients). Screw placement accuracy assessed by post-procedure CT scan was 95.7% (89/93 inserted screws). A total of 93 pedicle screw placements (36 bi-pedicular and 21 unipedicular) in 32 lumbar, 22 thoracic, and 3 cervical levels were analyzed. Mean reported procedure time was 48.8 (SD = 14.7) min and average injected cement volume was 4.4 (SD = 0.9) mL. A mean VAS score decrease of 5 points was observed at 1-month follow-up (7.7, SD = 1.3 versus 2.7, SD = 1.7), p < .001. CONCLUSION Combining a vertebroplasty and pedicle screw insertion is technically viable in the radiological setting, with a high screw positioning accuracy of 95.7%.

Reconstruction with antibiotic loaded single-side gore-tex "Tartine" methyl-methacrylate cementoplasty for pediatric chest wall reconstruction: A 10-case series. Orthop Traumatol Surg Res 2024:103895. [PMID: 38657749 DOI: 10.1016/j.otsr.2024.103895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Revised: 04/08/2024] [Accepted: 04/18/2024] [Indexed: 04/26/2024]
Abstract
INTRODUCTION Chest wall reconstruction in children after large resection of tumors may be performed with rigid or soft materials. Cementoplasty is commonly used with the "Sandwich" method i.e. gore-tex meshes surrounding both faces of the cement. HYPOTHESIS Is antibiotic loaded single-side gore-tex "Tartine" methyl-methacrylate cementoplasty an interesting alternative to the double-side "sandwich" method for chest wall reconstruction? MATERIAL AND METHODS Consecutive patients who were treated from 2011 to 2023 in our hospital were included. RESULTS Among the ten children treated with a median 5.6 years follow-up, there were no surgical complications related to the reconstruction, loss of function, infections, post operative complications (versus 22.7% in meta-analysis encompassing the 50 rigid reconstructions reported worldwide) nor scoliosis (versus 25%). Three patients have an asymmetric chest wall appearance. DISCUSSION "Tartine" cementoplasty is a simple, low-cost technique for pediatric chest wall reconstruction. It is well tolerated and checks key demands for chest wall reconstructions. LEVEL OF EVIDENCE IV; retrospective case series.

Transoral percutaneous radiofrequency ablation with a steerable needle and cementoplasty under CBCT and infrared augmented reality navigation system guidance for the treatment of a C1 solitary plasmacytoma: A case report. Radiol Case Rep 2024; 19:890-894. [PMID: 38188956 PMCID: PMC10770508 DOI: 10.1016/j.radcr.2023.11.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/03/2023] [Accepted: 11/06/2023] [Indexed: 01/09/2024] Open
Abstract
We report a case of a 40-year-old female with a solitary plasmacytoma of the right transverse apophysis of C1 who underwent combined transoral ablation using a curved steerable needle and cementoplasty under CBCT and infra-red augmented reality navigation system. An imaging work-up revealed an osteolytic lesion determining partial collapse of the right lateral mass of C1 and involving the vertebral foramen. After a biopsy, that revealed a solid tissue consistent with plasmacytoma, it was decided to proceed with radiation therapy. Subsequent PET-CT restaging scans showed residual tumors treated with a transoral percutaneous approach, combining ablation and cementoplasty. This report evaluates the benefits of this combined procedure and the transoral approach, focusing on the advantages of steerable devices and navigation systems.

Abstract
In recent years, interventional radiologists have been increasingly involved in the management of bone fractures resulting from benign (osteoporosis and trauma), as well as malignant (tumor-related impending or pathologic fractures) conditions. Interventional techniques used to fix fractures include image-guided osteoplasty, screw-mediated osteosynthesis, or combinations of both. In the present narrative review, we highlight the most common clinical scenarios that may benefit from such interventional techniques with specific focus on spine, pelvic ring, and long bones.

Abstract
Progressive population aging and improved healthcare have led to a significant increase in patients with hip arthroplasty (HA). In this patient group, the proportion of those who require a new arthroplasty (prosthetic replacement or secondary revision of the hip), has also increased. For this subgroup of patients in whom surgical prosthetic replacement should be considered but is contraindicated, a new technique has been developed since 2010: percutaneous injection of periprosthetic cement under fluoroscopic or CT control ("femoroplasty; FMP") as an alternative and less invasive treatment compared to surgery to stabilize the HA without replacing it, with excellent results on patients' quality of life. In this brief communication, we describe our positive experience regarding FMP, which we have performed for the first time in Spain on four patients (age range between 74-83 years, 2 female and 2 male patients, 3 right HA and 1 left HA), without post-complications. We highlight both the relative simplicity of this technique, which can be incorporated into radiological intervention even in regional hospitals, and the significant clinical improvement observed in all patients. In conclusion, we hope that our experience can contribute to the increased adoption of this innovative technique within the scientific community.

Comparison of Percutaneous Interventional Ablation-Osteoplasty-Reinforcement-Internal Fixation (AORIF), Long Intramedullary Nailing, and Hemiarthroplasty for the Treatment of Focal Metastatic Osteolytic Lesions in the Femoral Head and Neck. Cardiovasc Intervent Radiol 2023; 46:649-657. [PMID: 37052716 DOI: 10.1007/s00270-023-03425-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 03/17/2023] [Indexed: 04/14/2023]
Abstract
PURPOSE Osteolytic metastatic lesions in the femoral head and neck are traditionally treated with intramedullary long nailing (IM) or hemiarthroplasty (HA). Recovery, surgical complications, and medical co-morbidities delay oncologic care. This study sought to elucidate the comparative efficacy of percutaneous ablation-osteoplasty-reinforcement-internal fixation (AORIF), IM, and HA in stabilizing osteolytic lesions in the femoral head and neck. METHODS A retrospective study of 67 patients who underwent IM, AORIF, or HA for osteolytic femoral head and neck lesions was performed. Primary outcome was assessed using a combined pain and ambulatory score (Range 1-10: 1 = bedbound, 10 = normal ambulation) at first follow-up (~ 2 weeks). Surgical complications associated with each treatment were compared. RESULTS Sixty-seven patients (mean age, 65 ± 13, 36 men and 31 women) underwent IM (40), AORIF (19), and HA (8) with a mean follow-up of 9 ± 11 months. Two patients in the IM group (5%), three in the AORIF group (16%), and none in the HA (0%) group required revision procedures. AORIF demonstrated superior early improvement in combined pain and ambulatory function scores by 3.0 points [IQR = 2.0] (IM p = 0.0008, HA p = 0.0190). Odds of post-operative complications was 10.3 times higher in HA than IM (95% confidence interval 1.8 to 60.3). Future revision procedures were not found to be statistically significant between AORIF and IM (p = 0.234). CONCLUSIONS A minimally invasive interventional skeletal procedure for focal femoral head and neck osteolytic lesions may serve as an effective alternative treatment to traditional surgical approaches, conferring a shorter recovery time and fewer medical complications.

Abstract
OBJECTIVES To assess the feasibility and technical outcomes of pelvic bone cementoplasty using an electromagnetic navigation system (EMNS) in standard practice. MATERIALS AND METHODS Monocentric retrospective study of all consecutive patients treated with cementoplasty or reinforced cementoplasty of the pelvic bone with EMNS-assisted procedures. The endpoints were periprocedural adverse events, needle repositioning rates, procedure duration, and radiation exposure. RESULTS A detailed description of the technical steps is provided. Thirty-three patients (68 years ± 10) were treated between February 2016 and February 2020. Needle repositioning was required for 1/33 patients (3%). The main minor technical adverse event was soft tissue PMMA cement leaks. No major adverse event was noted. The median number of CT acquisitions throughout the procedures was 4 (range: 2 to 8). Radiation exposure and mean procedure duration are provided. CONCLUSION Electromagnetic navigation system-assisted percutaneous interventions for the pelvic bone are feasible and lead to low rates of minor technical adverse events and needle repositioning. Procedure duration and radiation exposure were low. KEY POINTS • Initial experience for 33 patients treated with an electromagnetic navigation assistance for pelvic cementoplasty shows feasibility and safety. • The use of an electromagnetic navigation system does not expose to high procedure duration or radiation exposure. • The system is efficient in assisting the radiologist for extra-axial planes in challenging approaches.

Abstract
The role of interventional radiology (IR) is expanding. With new techniques being developed and tested, this radiology subspecialty is taking a step forward in different clinical scenarios, especially in oncology. Musculoskeletal tumoral diseases would definitely benefit from a low-invasive approach that could reduce mortality and morbidity in particular. Thermal ablation through IR has already become important in the palliation and consolidation of bone metastases, oligometastatic disease, local recurrences, and treating specific benign tumors, with a more tailored approach, considering the characteristics of every patient. As image-guided ablation techniques lower their invasiveness and increase their efficacy while the collateral effects and complications decrease, they become more relevant and need to be considered in patient care pathways and clinical management, to improve outcomes. We present a literature review of the different percutaneous and non-invasive image-guided thermal ablation methods that are currently available and that could in the future become relevant to manage musculoskeletal oncologic diseases.

Abstract
BACKGROUND The spine is the most frequently affected part of the skeletal system to metastatic tumors. External radiotherapy is considered the first-line standard of care for these patients with spine metastases. Recurrent spinal metastases after radiotherapy cannot be treated with further radiotherapy within a short period of time, making treatment difficult. We aimed to evaluate the effectiveness and safety of MWA combined with cementoplasty in the treatment of spinal metastases after radiotherapy under real-time temperature monitoring. METHODS In this retrospective study, 82 patients with 115 spinal metastatic lesions were treated with MWA and cementoplasty under real-time temperature monitoring. Changes in visual analog scale (VAS) scores, daily morphine consumption, and Oswestry Disability Index (ODI) scores were noted. A paired Student's t-test was used to assess these parameters. Complications during the procedure were graded using the CTCAE version 5.0. RESULTS Technical success was attained in all patients. The mean VAS score was 6.3 ± 2.0 (range, 4-10) before operation, and remarkable decline was noted in one month (1.7 ± 1.0 [P < .001]), three months (1.4 ± 0.8 [P < .001]), and six months (1.3 ± 0.8 [P < .001]) after the operation. Significant reductions in daily morphine consumption and ODI scores were also observed (P < .05). Cement leakage was found in 27.8% (32/115) of lesions, with no obvious associated symptoms. CONCLUSION MWA combined with cementoplasty under real-time temperature monitoring is an effective and safe method for recurrent spinal metastases after radiotherapy.

Extraction of cement leakages and malpositioned spindles complicating percutaneous interventions: why, when and how? Eur Radiol 2022; 32:7632-7639. [PMID: 35449235 DOI: 10.1007/s00330-022-08787-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Revised: 03/08/2022] [Accepted: 03/30/2022] [Indexed: 01/03/2023]
Abstract
OBJECTIVES Cement leakages in soft tissues are a common occurrence during cementoplasty. They may cause chronic pain, and thus treatment failure. Spindle malposition during reinforced cementoplasty may cause vascular, nerve or cartilage injury. Our goal was to evaluate the rate of cement leakage/spindle extraction and describe the techniques used. METHODS This retrospective monocentre study included 104 patients who underwent reinforced cementoplasty and 3425 patients who underwent cementoplasty between 2012 and 2020. Operative reports and fluoroscopic images were reviewed to identify extraction attempts and their outcomes. RESULTS Six patients (5.8%) had a malpositioned spindle, and all of them underwent spindle extraction during reinforced cementoplasty, with an 80% success rate. A total of 7 attempts were performed, using 2 different techniques. One thousand one hundred thirty patients (32%) had a cement leak in soft tissues, and 7 (0.6%) underwent cement leakage extraction during cementoplasty, with a 100% success rate. A total of 10 attempts were performed, using 3 different techniques. No major complication related to the extraction procedures occurred. CONCLUSIONS Spindle malpositions and soft tissue cement leakages are not uncommon. We described 5 different percutaneous techniques that were safe and effective to extract spindles and paravertebral cement fragments. KEY POINTS • Soft tissue cement leakages or spindle malpositions are a non-rare occurrence during cementoplasty, and may cause technical failure and/or chronic pain. • Most soft tissue cement fragments and malpositioned spindles can easily be extracted using simple percutaneous techniques.

Abstract
OBJECTIVES To describe a novel long-axis multimodal navigation assisted technique - the so-called Eiffel Tower technique - aimed at integrating recent technological improvements for the routine treatment of sacral insufficiency fractures. MATERIALS AND METHODS The long-axis approach described in the present study aimed at consolidating the sacral bone according to biomechanical considerations. The purpose was (i) to cement vertically the sacral alae all along and within the lateral fracture lines, resembling the pillars of a tower, and (ii) to reinforce cranially with a horizontal S1 landing zone (or dense central bone) resembling the first level of the tower. An electromagnetic navigation system was used in combination with CT and fluoroscopic guidance to overtop extreme angulation challenges. All patients treated between January 2019 and October 2021 in a single tertiary center were retrospectively reviewed. RESULTS A description of the technique is provided. Twelve female patients (median age: 80 years [range: 32 to 94]) were treated for sacral insufficiency fractures with the "Eiffel Tower" technique. The median treatment delay was 8 weeks (range: 3 to 20) and the initial median pain assessed by the visual analogue scale was 7 (range: 6 to 8). Pain was successfully relieved (visual analogue score < 3) for 9 patients (75%) and persisted for 2 patients (17%). One patient was lost during the follow-up. No complication was noted. CONCLUSION The "Eiffel Tower" multimodal cementoplasty integrates recent technological developments, in particular electromagnetic navigation, with the purpose of reconstructing the biomechanical chain of the sacral bone. KEY POINTS • Sacral insufficiency fractures are common and can be efficiently treated with percutaneous sacroplasty. • The long axis sacroplasty approach can be challenging given both the shape of the sacral bone and the angulation to reach the target lesion. • The "Eiffel Tower" technique is a novel approach using electromagnetic navigation to expand the concept of the long axis route, adding a horizontal S1 landing zone.

Abstract
OBJECTIVE To evaluate feasibility, safety and efficacy of a combination of screw fixation and cementoplasty for pathologic bone fracture. METHODS In this single-center prospective study, all consecutive percutaneous screw fixations under assisted CT guidance for palliation and fracture treatment of pathologic bone fracture were reviewed from July 2019 to February 2021. The primary outcome measure was the procedures' technical success, defined as the correct placement of the screw(s), without any complications. Secondary outcome measures were the safety, the procedures' early analgesic effects and impacts on quality of life at 4 weeks. RESULTS Technical success was achieved in 11/11 procedures (100%) among 11 patients. No major complications attributable to the procedure were noted. The mean pain scored significantly decreased at the initial follow-up: 8.0 ± 2.7 versus 1.6 ± 2.5 (p < 0.05). Opioid doses were statistically lower after procedure: 70.9 ± 37 versus 48.2 ± 46 mg/day (p < 0.05). The mean EQ5D score had significantly increased by the early post-procedure consultation: 42.5 ± 13.6 vs 63.6 ± 10.3 (p < 0.05). CONCLUSION Combination of percutaneous screw fixation and cementoplasty for pathologic bone fracture is feasible and safe. It is efficient to reduce pain, decrease the consumption of opioids and improve the quality of life at 4 weeks after the procedure.

Abstract
OBJECTIVES Pelvic bone pathological lesions and traumatic fractures are a considerable source of pain and disability. In this study, we sought to evaluate the effectiveness of reinforced cementoplasty (RC) in painful and unstable lesions involving the pelvic bone in terms of pain relief and functional recovery. METHODS All patients with neoplastic lesion or pelvic fracture for whom a pelvic bone RC was carried out between November 2013 and October 2017 were included in our study. All patients who failed the medical management, patients unsuitable for surgery, and patients with unstable osteolytic lesions were eligible to RC. Clinical outcome was evaluated with a 1-month and 6-month post-procedure follow-up. The primary endpoint was local pain relief measured by the visual analogue scale (VAS). RESULTS Twenty-two patients (18 females, 4 males; mean age of 65.4 ± 13.3 years [range 38-80]) presenting with painful and unstable pelvic lesions were treated by RC during the study period. Among the 22 patients, 8 patients presented with unstable pelvic fractures (3 patients with iliac crest fracture, 3 with sacral fractures, and the remaining 2 with peri-acetabular fractures). No procedure-related complications were recorded. All patients had significant pain relief and functional improvement at 1 month. One patient (4.5%) had suffered a secondary fracture due to local tumour progression. CONCLUSIONS Reinforced cementoplasty is an original minimally invasive technique that may help in providing pain relief and effective bone stability for neoplastic and traumatic lesions involving the pelvic bone. KEY POINTS • Reinforced cementoplasty is feasible in both traumatic fractures and tumoural bone lesions of the pelvis. • Reinforced cementoplasty for pelvic bone lesions provides pain relief and functional recovery. • Recurrence of pelvic bone fracture was observed in 4.5% of the cases in our series.

Biomechanical restoration of metastatic cancer-induced peri-acetabular bone defects by ablation-osteoplasty-reinforcement-internal fixation technique (AORIF): To screw or not to screw? Clin Biomech (Bristol, Avon) 2022; 92:105565.

Abstract
BACKGROUND Minimally invasive percutaneous polymethyl methacrylate cement augmentation procedures offer numerous clinical advantages for patients with periacetabular osteolytic metastatic bone defects in contrast to open reconstructive procedures that are associated with many complications. Several techniques, such as Ablation-Osteoplasty-Reinforcement-Internal Fixation (AORIF), cementoplasty alone, and screw fixation alone are currently used. There is no consensus on optimal skeletal reinforcement of diseased bones. The purpose of this study was to determine the most effective technique of percutaneous acetabular augmentation for joint preservation, with respect to resilience on cyclic loading and fracture pattern at maximal load to failure. METHODS Five cohorts of hemipelvis composite bones with uniform periacetabular defects and various types of reinforcement techniques were utilized to simulate osteolytic metastasis in the weight bearing dome of the acetabulum. Five groups of hemipelves underwent finite element analysis and biomechanical testing for load to failure, energy absorption to failure, stress relaxation on cyclic loading, and fracture locations. RESULTS The combination of screws and bone cement augmentation demonstrated significant higher energy absorption than the cement or screw only groups (p < 0.05), and better protection of acetabulum from displaced intraarticular fractures than the screws alone oror cement only groups (p < 0.05). Resilience to cyclic loading was higheest in the screw with cement fixation group than the screw only repair (p < 0.01), though not the cement fixation only group. INTERPRETATION These data support the hypothesis that cementoplasty combined with screw augmentation such as the AORIF technique provides the best protection of acetabulum from massive metastatic cancer-induced acetabular fractures compared to augmentation with screws or cement alone.

CT-Guided Percutaneous Vertebroplasty of the Cervico-Thoracic Junction for the Management of Pathologic Fracture or Symptomatic Lytic Lesion in Cancer Patients. Cardiovasc Intervent Radiol 2021; 45:244-248. [PMID: 34853875 DOI: 10.1007/s00270-021-03018-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2021] [Accepted: 09/29/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVES The purpose of this retrospective observational study is to report author's experience in computed-tomography (CT)-guided percutaneous vertebroplasty (PV) of the cervicothoracic junction. METHODS The records of all consecutive patients treated by PV at levels C7, T1, T2, and T3 in a tertiary cancer center during year 2020 were extracted from the Institutional electronic archive. Following data were collected: demographics, indication for PV, procedure features, outcomes, and complications. Technical success was defined as when the trocar was placed into the vertebral body, allowing the injection of polymethyl-metacrylate (PMMA). RESULTS Eleven patients were identified who received PV on 14 levels. Mean procedure duration was 57 ± 22 min (range [31-142]). A "trans-pedicular approach at the targeted level" was used in 1 vertebra (7%), a "costotransverse approach, at the targeted level" was used in 1 vertebra (7%), a "transpedicular approach via the level below" was used in 3 vertebrae (22%), and a "costotransverse approach via the level below" was used in 9 vertebrae (64%). Meantime to deploy each trocar was 20 ± 5 min (range [12-32]). Technical success was achieved in 14/14 (100%) of vertebrae. Mean postoperative hospitalization duration was 1.9 ± 1.7 days (range [1-11]). According to CIRSE classification, no adverse event occurred. PMMA leakage occurred in two patients; both remained asymptomatic. CONCLUSION This study provides arguments in favor of safety and efficiency of CT-guided vertebroplasty of levels C7, T1, T2, and T3, for both trocar deployment and monitoring of the vertebral body filling during the PMMA injection.

Abstract
Metastatic bone disease is a common complication of malignant tumours. As cancer treatment improves the overall survival of patients, the number of patients with bone metastases is expected to increase. The treatments for bone metastases include surgery, radiotherapy, and bone-modifying agents, with patients with a short expected prognosis requiring less invasive treatment. Patients with metastatic bone disease show greatly varying primary tumour histology, metastases sites and numbers, and comorbidities. Therefore, randomised clinical trials are indispensable to compare treatments for these patients. This editorial reviews recent findings on the diagnosis and prognosis prediction and discusses the current treatment of patients with metastatic bone disease.

Percutaneous osteoplasty for painful bony lesions: a technical survey. Korean J Pain 2021; 34:375-393. [PMID: 34593656 PMCID: PMC8494954 DOI: 10.3344/kjp.2021.34.4.375] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Revised: 07/09/2021] [Accepted: 07/14/2021] [Indexed: 12/01/2022] Open
Abstract
Percutaneous osteoplasty (POP) is defined as the injection of bone cement into various painful bony lesions, refractory to conventional therapy, as an extended technique of percutaneous vertebroplasty (PVP). POP can be applied to benign osteochondral lesions and malignant metastatic lesions throughout the whole skeleton, whereas PVP is restricted to the vertebral body. Common spinal metastases occur in the thoracic (70%), lumbosacral (20%), and cervical (10%) vertebrae, in order of frequency. Extraspinal metastases into the ribs, scapulae, sternum, and humeral head commonly originate from lung and breast cancers; extraspinal metastases into the pelvis and femoral head come from prostate, urinary bladder, colon, and uterine cervical cancers. Pain is aggravated in the dependent (or weight bearing) position, or during movement (or respiration). The tenderness and imaging diagnosis should match. The supposed mechanism of pain relief in POP is the augmentation of damaged bones, thermal and chemical ablation of the nociceptive nerves, and local inhibition of tumor invasion. Adjacent (facet) joint injections may be needed prior to POP (PVP). The length and thickness of the applied needle should be chosen according to the targeted bone. Bone cement is also selected by its osteoconduction, osteoinduction, and osteogenesis. Needle route should be chosen as a shortcut to reach the target bony lesions, without damage to the nerves and vessels. POP is a promising minimally invasive procedure for immediate pain relief. This review provides a technical survey for POPs in painful bony lesions.

Abstract
OBJECTIVE To explore clinical effect of cement-augmented pedicle screw combined with vertebroplasty in treating Kümmell disease with type Ⅲ. METHODS From January 2015 to December 2018, 37 patients with type Ⅲ Kümmell disease were retrospectively analyzed, including 11 males and 26 females, aged from 61 to 84 years old with an average of (68.6±4.2) years old, and the courses of disease ranged from 2 to 10 months with an average of(6.5±2.3) months. Nine patients were grade C, 20 patients were grade D and 8 patients were grade E according to Frankle grading. All patients were treated by cement-augmented pedicle screw combined with vertebroplasty. Operation time, blood loss, postoperative drainage, hospital stay and complicationswere observed after oeprtaion. Visual analogue scale(VAS), Oswestry Disability Index(ODI), height of anterior vertebral body, Cobb angle before and after operation were compared. RESULTS All patients were followed up from 12 to 60 months with an average of (22.4±10.9) months. Operation time was (240.9±77.4) min, blood loss was (315.0±149.2) ml, postoperative drainage was (220.8±72.0) ml, hospital stay was (12.6±4.7) days. One patient occurred incision redness and 1 patient occurred infection after opertaion. No loosening of bone cement occurred. Postopertaive VAS and ODI were lower than that of before opertaion(P<0.05), height of anterior vertebral body after opertaion was larger than that of before opertaion, Cobb angle after operation was less than that of before operation (P<0.05). According to Frankle grading of never function at the latest follow up, 2 patients were grade D and 35 patients were grade E. Nerve function and quality of life was improved. CONCLUSION Cement-augmented pedicle screw combined with vertebroplasty is a safe and effective method for the tretament of Kümmell disease with type Ⅲ.

Abstract
PURPOSE The purpose of this study was to retrospectively assess the safety profile of percutaneous image-guided screw fixation (PIGSF) for insufficiency, impending or pathological fractures. MATERIALS AND METHODS From July 2012 to April 2020, all consecutive patients who underwent PIGSF were retrospectively included in the study. Patient characteristics, fracture type, procedural data and complications were analyzed. Complications were divided into per-procedural, early (<24hours) and delayed (>24hours) and classified into minor (grade 1-2) and major complications (grade 3-5) according to Common Terminology Criteria for Adverse Events (CTCAE) v5.0. RESULTS A total of 110 fractures (40 insufficiency [36%], 53 pathological [48.5%] and 17 impending [15.5%] fractures) in 94 patients (48 women, 46 men; mean age, 62.7±12.7 [SD] years; age range: 32-88 years) were treated with PIGSF during 95 procedures. Twenty-four-hours follow-up was available for all patients, and>24-hours follow-up was available for 79 (79/110; 71.8%) fractures in 69 (69/94; 73.4%) patients. Per-procedural complications occurred in 3/110 fractures (2.7%, all minor). Early complications were reported in 4/110 fractures (3.6%, 1 major and 3 minor) and delayed ones in 14/79 fractures (17.7%, 5 major and 9 minor). The most frequent major delayed complication was infection (3/79; 3.8%). CONCLUSION The rate of per-procedural and early (within 24hours) complications following PIGSF is extremely low with most complications being minor, with major complications being delayed ones (>24hours).

Cement Plug Fragmentation Following Percutaneous Cementoplasty of the Bony Pelvis: Is it a Frequent Finding in Clinical Practice? Cardiovasc Intervent Radiol 2020; 44:421-427. [PMID: 33241471 DOI: 10.1007/s00270-020-02715-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2020] [Accepted: 11/12/2020] [Indexed: 10/22/2022]
Abstract
PURPOSE To report the rate of fragmentation of the cement plug following percutaneous cementoplasty with polymethylmethacrylate (PMMA) in the bony pelvis (i.e., pelvic bones or sacrum). MATERIALS AND METHODS Post-interventional and follow-up CT scans of 56 patients (36 men; mean age of 68.4 ± 15.4) with a total of 98 percutaneous cementoplasty procedures were analyzed. Indications for treatment included painful malignant tumors (42.9%; 42/98) and insufficiency fractures (57,1%; 56/98). Fragmentation of PMMA was recorded for each cement plug. RESULTS Mean interval between the procedure and the last available CT scan was 29.3 ± 18.8 months. There was no significant difference between the length of follow-up of malignant lesions (27.6 ± 15.1 months) and insufficiency fractures (29 ± 20.5 months) (p = 0.69). Fragmentation was diagnosed following 2/98 (2%) procedures, both in the malignant lesions group. The time intervals between the procedure and the first visualization of cement fragmentation were 6 for the first and 24 months for the second patient. CONCLUSION Fragmentation of the PMMA plug following percutaneous cementoplasty in the bony pelvis is a rare finding at midterm follow-up. It was only observed in cementoplasty performed in malignant lesions and seems to be more a consequence of local mechanical stresses than as a result of porosity.

Percutaneous cementoplasty of periprosthetic loosening: can interventional radiologists offer an alternative to revision surgery? Eur Radiol 2020; 31:4221-4231. [PMID: 33201283 DOI: 10.1007/s00330-020-07463-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 09/16/2020] [Accepted: 11/03/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVE To evaluate feasibility and validate both safety and efficiency of radiological percutaneous periprosthetic bone cementoplasty (RPPBC) performed under local anesthesia as an alternative minimally invasive treatment of aseptic implant loosening. METHODS In this case series, seven patients (mean age 81 years, range 73 to 89 years, 2 men and 5 women) were enrolled between February 2011 and January 2020 with confirmed aseptic loosening of orthopedic implants. One patient presented with tibial component loosening of an unicompartmental knee arthroplasty, one with glenoid component loosening from a reverse shoulder arthroplasty, one femoral gamma nail, and four presented with pedicle screw loosening after staged posterior lumbar interbody fusion. All patients underwent clinical, biochemical, and imaging assessments to confirm the diagnosis of aseptic loosening. All benefited from RPPBC under dual CT and fluoroscopic guidance. All procedures were performed under local anesthesia by an experienced radiologist. Preprocedural, immediate and 6-month post-cementoplasty pain levels on a visual analogue scale (VAS), and functional outcomes were evaluated. Immediate and 6-month postprocedural CTs were performed to evaluate the treated region. RESULTS All RPPBC were well tolerated by patients throughout the procedure. None of the patients suffered from local or systemic infection post-RPPBC, or periprosthetic fractures. No recurrent implant loosening was observed. Six patients were pain free at 6 months. All patients expressed functional improvements during validated outcome score evaluations. CONCLUSION RPPBC appears to be an efficient and reliable treatment strategy for aseptic loosening of orthopedic implants in elderly patients deemed unfit for revision surgery. KEY POINTS • Radiological percutaneous periprosthetic bone cementoplasty offers immediate and long-lasting pain relief in elderly frail patients, or those deemed unfit for revision surgery despite presenting with symptomatic aseptic loosening of orthopedic implants. • Radiological percutaneous periprosthetic bone cementoplasty brings quick and long-lasting improvements in clinical functional outcomes and offer effective pain reduction, thereby improving the overall quality of life. • Radiological percutaneous periprosthetic bone cementoplasty is a safe, quick, reliable, and well-tolerated minimally invasive procedure which can be easily performed under simple locoregional anesthesia and requires short-term hospital stay.

Retrospective, multicenter, observational study of 112 surgically treated cases of humerus metastasis. Orthop Traumatol Surg Res 2020; 106:1047-1057. [PMID: 32768275 DOI: 10.1016/j.otsr.2020.02.025] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 02/18/2020] [Accepted: 02/27/2020] [Indexed: 02/03/2023]
Abstract
INTRODUCTION The humerus is the second most common site for metastasis in the peripheral skeleton. These humeral metastases (HM) occur in the midshaft in 42% to 61% of cases and theproximal humerus in 32% to 45% of cases. They are often secondary to primary breast (17-31%), kidney (13-15%) or lung (11-24%) cancer. The optimal surgical treatment between intramedullary (IM) procedures, fixation or arthroplasty is still being debated. HYPOTHESIS We hypothesized that fixation and/or arthroplasty are safe and effective options for controlling pain and improving the patients' function. MATERIALS AND METHODS Between 2004 and 2016, 11 French hospitals included 112 continuous cases of HM in 54 men (49%) and 57 women (51%). The average age was 63.7±13.4 years (30-94). The HM occurred in the context of primary breast (30%), lung (23%) or kidney (21%) cancers. The HM was proximal in 35% of cases, midshaft in 59% and distal in 7% of cases. Surgery was required in 69% of patients because of a pathological fracture. The surgical procedure consisted of bundle pinning, plate fixation, arthroplasty or locked IM nailing in 6%, 11%, 14% and 69% of patients, respectively. RESULTS Seven patients (6%) had to be reoperated due to surgical site complications including two infections and four fractures (periprosthetic or away from implant). Twelve patients (11%) experienced a general complication. The overall survival was 16.7 months, which was negatively and significantly impacted by the occurrence of a fracture, a diaphyseal location and the type of primary cancer. At the final assessment, 75% had normal or subnormal function and more than 90% were pain-free or had less pain. The final function was not related to the occurrence of a fracture or etiology of the metastasis. In epiphyseal and metaphyseal HM, there was a trend to better function after shoulder arthroplasty than after plate fixation or IM nailing. CONCLUSIONS Our initial hypothesis was confirmed. Our findings were consistent with those of other published studies. Based on our findings, we recommend using static locked IM nailing with cementoplasty for mid-shaft lesions and modular arthroplasty for destructive epiphyseal or metaphyso-epiphyseal lesions. The criteria for assessing humeral fracture risk should be updated to allow the introduction of a preventative procedure, which contributes to better survival. LEVEL OF EVIDENCE IV, retrospective study.

Abstract
PURPOSE To assess safety and efficacy of multi-level vertebroplasty, when treating 6 or more levels in the same procedural setting for the management of osteoporotic vertebral compression fractures (oVCF) in cancer patients. MATERIALS AND METHODS Single institution retrospective review from 2015 to 2019 of patients treated for multi-level oVCF in a single session procedural setting by vertebroplasty of 6 or more levels. Procedure outcomes collected included procedural complications, pre- and 4 week post-procedure pain score by numeric rating scale, opioid usage, and vertebral height changes. RESULTS In total, 197 vertebral levels were treated in 24 procedures (mean 8.2 ± 1.8 levels). Mean procedure duration was 167 + / - 41 min, and mean postoperative hospitalization duration was 2.1 + / - 1.9 days. Four grade I or II complications occurred according to CIRSE classification. Two patients had a symptomatic pulmonary cement embolism; although there was no statistical difference between pre- and postoperative mean blood saturation (95.9 + / - 1.7% and 94.8 + / - 2.0%, respectively, p = 0.066). Pain score significantly improved after treatment (6.5 ± 1.3 vs 3.2 + / - 1.4, p < 0.0001) with a mean decrease of 3.3 (51%). Post-procedure daily opioid use also significantly improved (mean 35.8 + / - 36.8 mg/24 h vs 18.5 + / - 27.8 mg/24 h, p = 0.0089), with a mean decrease of 17.3 mg/24 h (48%). Refracture was found in 2 of 105 levels treated (1.9%), and no difference was found in thoraco-lumbar height and angulation. Five patients experienced new painful fractures at a non-treated level. CONCLUSION Multi-level vertebroplasty for 6 or more levels is a safe and effective treatment for the management of multi-level oVCF in cancer patients.

Abstract
Background The purpose of this study was to review recent research related to the analgesic effect of ablation therapy combined with cementoplasty, as well as to identify the duration of analgesic effect and risk for cement leaks. Methods A systematic literature search using PubMed, Web of Science, and annual meeting proceedings of the oncology society and other organizations were conducted. Results Twelve retrospective studies met the inclusion criteria. Four of the studies included in the review assessed the changes immediately after treatment. Five studies were subjected to analyses of analgesic effect of combined percutaneous thermal ablation and Cementoplasty at 24 weeks after treatment. Incidences of leakage of bone cement during surgery were detected in 4 out of 12 studies. The change of mean pain scores at 1 days, at 1 week, and at 4 weeks, 12 weeks, and 24 weeks after treatment were -3.90 (95% CI: -4.80 to -3.00), -4.55 (95% CI:-5.46 to -3.64), -4.78 (95% CI: -5.70 to -3.86), -5.16 (95% CI: -6.39 to -3.92), and -5.91 (95% CI: -6.63 to -5.19). The relative risk of cement leakage was 0.10 (95% CI: -6.63 to -5.19). Conclusions Our systematic review suggested that thermal ablation combined with cementoplasty could be a safe and effective intervention for the management of bone metastases-induced pain.

Abstract
PURPOSE To evaluate the feasibility, efficacy and safety of sternal percutaneous fixation by internal cemented screw (FICS) using fluoroscopy and/or CT needle guidance. MATERIALS AND METHODS This retrospective single-center study analyzed 9 consecutive cancer patients managed with percutaneous FICS for sternal fracture fixation or osteolytic metastasis consolidation, from May 2014 to February 2019. Eastern Cooperative Oncology Group performance status, Numeric Pain Rating Scale (NPRS) and opioid use were studied preoperatively and postoperatively. Sternal images at last follow-up appointment were also collected. RESULTS Among the 9 patients, 7 had a sternal fracture with 5 being displaced. The technical feasibility was 100%. Both NPRS score significantly decreased from 5.6/10 ± 2.8 to 1.1/10 ± 1.6, and analgesic consumption was significantly improved (p = 0.03) after intervention. No post-procedural complications requiring surgical correction or screw displacement occurred after a mean imaging follow-up that exceeded 1 year (mean follow-up duration, 401.8 days ± 305.8). CONCLUSION Image-guided sternal percutaneous FICS is feasible and safe. It reduces pain and analgesic consumption related to pathologic fracture of the sternum.

Abstract
OBJECTIVES To evaluate lesion filling and other factors that could affect the clinical outcomes of cementoplasty for pelvic bone metastases. METHODS We retrospectively reviewed the files of 40 patients treated for 44 pelvic bone metastases, collected the parameters related to patients (pain relief evaluated on a visual analog scale, subsequent fractures, and need for surgery), lesions (size, cortical breach score, fracture, soft-tissue extension), and cementoplasty procedures (number of needles, volume of cement, percentage of lesion filling, cement leaks, residual acetabular roof defect), and performed a statistical analysis. RESULTS The lesions were on average 43.2 mm in diameter and the mean cortical breach score was 2.5 out of 6, with a pathological fracture in 14 lesions. The number of needles inserted was one in 32 out of 44, two in 10 out of 44, and three in 2 out of 44. On average, the volume of cement injected per lesion was 10.3 ml and the filling was 54.8%. Mild or moderate asymptomatic cement leakage occurred in 20 lesions (45.5%). The mean pain score was 84.2 mm before the procedure (with no correlation with lesion size, cortical breach score or fracture) and 45.6 mm at follow-up. The pain relief of 38.6 mm was statistically significant (p < 0.001) and did not correlate with the filling percentage. There were no fractures of the treated lesions at a mean follow-up of 355 days. CONCLUSIONS Cementoplasty of pelvic bone metastases appears effective for providing pain relief and may prevent subsequent fractures. We were unable to demonstrate a correlation between the lesion filling and the degree of pain relief.

OBJECTIVE To investigate clinical effect of percutaneous vertebroplasty with second injection for poor dispersion bone cement of Kümmel disease. METHODS Eighty-eight patients with Kümmel disease were treated with vertebroplasty from February 2014 to December 2017, and 16 patients were found cement dispersion unsatisfactory during initial cement injection and were undertaken second cement injection during operation. Among patients, there were 1 male and 15 females aged from 63 to 82 years old with an average age of 72.7 years old. Distribution of fractured vertebrae were followed: 1 patient was on T₁₀, 1 patient was on T₁₁, 3 patients were on T₁₂, 8 patients were on L₁, 1 patient was on L₂, and 2 patients were on L₃. VAS and ODI score were compared before operation, 2 days after operation and the latest following-up, anterior vertebral height and local kyphosis angle of fractured vertebrae with intravertebral cleft were also observed. Postoperative complication was recorded. RESULTS All patients were followed up from 5 to 22 months with average of 14.1 months. ODI score before operation, 2 days after operation and the latest following-up were 72.3±12.1, 56.8±5.0 and 12.1±5.3 respectively; VAS score before operation, 2 days after operation and the latest following-up were 7.8±0.6, 3.0±0.4 and 2.4±0.7, respectively; ODI score at 2 days was improved compared with before operation, while ODI and VAS score at the latest following-up was improved than that of 2 days after operation. Vertebral anterior compression rate and Cobb angle of the fractured vertebrae with intravertebral cleft were respectively corrected from (37.8±5.4)% and (15.1±2.0)°preoperative, to (4.7±1.4)% and (4.4±2.2)° at 2 days after operation, (4.9±1.5)% and (4.8±2.4)° at the latest following-up, there was significant difference between before operation and 2 days after operation, while there was no difference between 2 days after operation and the latest following-up. Three patients occurred cement leakage without pulmonary embolism and neurological impairment. Four patients occurred adjacent vertebrae fracture. There was no incidence of recollapsed vertebrae during follow-up period. CONCLUSIONS Percutaneous vertebroplasty for Kümmel disease could receive satisfactory clinical results when cement dispersion was inadequate during initial cement injection by the second injection, and effectively prevent occurrence of vertebral re-collapse.

Preliminary results: use of multi-hole injection nails for intramedullary nailing with simultaneous bone cement injection in long-bone metastasis. Skeletal Radiol 2019; 48:219-225. [PMID: 29931418 DOI: 10.1007/s00256-018-2998-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2018] [Revised: 05/16/2018] [Accepted: 05/30/2018] [Indexed: 02/02/2023]
Abstract
OBJECTIVE For symptomatic metastasis of the long bones, intramedullary nailing has been the most accepted fixation method. Intramedullary nailing has effective control of pain, perioperative bleeding, and local tumor progression by augmentation with bone cement around the nail. Here, we report the preliminary results of a new surgical implant that allows for simultaneous injection of bone cement while inserting a percutaneous, flexible intramedullary nail. MATERIALS AND METHODS We performed palliative surgeries for long-bone metastasis using a multi-hole injection nail (MIN) with multiple side holes in the distal one third. When the nail tip entered the metastatic cancer lesion, the bone cement injection was started, and continued until the nail was completely seated. Ten patients with advanced cancer underwent palliative surgery using the new implant with simultaneous bone cement injection for humeral (n = 4), femoral (n = 4), and tibial (n = 2) metastases. RESULTS The mean operative time was 42 min (range, 36-52 min). The mean length of the injection nail was 23.0 cm (range, 18.0-33.0 cm), and the mean volume of cement was 28.0 ml (range, 14.0-40.0 ml). Marked pain palliation (p < 0.001) and functional recovery (p = 0.01) were verified. The mean Musculoskeletal Tumor Society (MSTS) functional score improved significantly from 12.5 at 6 weeks preoperatively, to 24.9 postoperatively. No acute postoperative complications, including cement embolism, occurred. CONCLUSION This minimally invasive surgical method with MIN could be useful for stabilization of long-bone metastases in patients with advanced cancer.

Bone-filling mesh container versus percutaneous kyphoplasty in treating Kümmell's disease. Arch Osteoporos 2019; 14:109. [PMID: 31741066 PMCID: PMC6861350 DOI: 10.1007/s11657-019-0656-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2019] [Accepted: 09/25/2019] [Indexed: 02/03/2023]
Abstract
UNLABELLED Kümmell's disease (eponymous name for osteonecrosis and collapse of a vertebral body due to ischemia and non-union of anterior vertebral body wedge fractures after major trauma) cannot heal spontaneously. Bone-filling mesh container (BFMC) can significantly relieve pain, help the correction of kyphosis, and may prevent cement leakage. This pilot study may provide the basis for the design of future studies. PURPOSE To compare the effectiveness and safety of BFMC and percutaneous kyphoplasty (PKP) for treatment of Kümmell's disease. METHODS From August 2016 to May 2018, 40 patients with Kümmell's disease were admitted to Guizhou Provincial People's Hospital. Among them, 20 patients (20 vertebral bodies) received PKP (PKP group) and the other 20 received BFMC (BFMC group). Operation time, Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), Cobb's angle changes, and related complications were recorded. RESULTS All patients underwent operations successfully. VAS scores and ODI of both groups at each postoperative time point were lower than preoperatively, with statistically significant difference (p < 0.05). Postoperative Cobb's angle of both groups postoperatively was lower than preoperatively (p < 0.05). Cement leakage occurred in eight vertebrae (8/20) in the PKP group and in one vertebra (1/20) in the BFMC group. No complications such as pulmonary embolism, paraplegia, or perioperative death occurred during operation in both groups. Adjacent vertebral refractures occurred in five patients (5/20) in the PKP group and in four patients (4/20) in the BFMC group, with no significant difference in the incidence rate of refractures in both groups but the material is too small to verify statistically. CONCLUSIONS Both PKP and BFMC technologies can significantly relieve pain and help the correction of kyphosis while treating Kümmell's disease. Moreover, the BMFC may prevent cement leakage.

Abstract
STUDY DESIGN Retrospective case series observational study. PURPOSE Cancer patients are often aged and are further weakened by their illness and treatments. Our goal was to evaluate the efficiency and safety of using minimally invasive techniques to operate on spinal fractures in these patients. OVERVIEW OF LITERATURE Vertebroplasty is now considered to be a safe technique that allows a significant reduction of the pain induced by a spinal tumoral fracture. However, few papers describe the kyphosis reduction that can be achieved by combining percutaneous fixation and anterior vertebral reconstruction. METHODS We studied 35 patients seen between December 2013 and October 2016 who had at least one pathological spinal fracture and multiple vertebral metastases. The population's mean age was 67 years, and no patients included had preoperative neurological deficits. The patients underwent a minimally invasive surgery consisting of a percutaneous pedicular fixation with cement-enhanced screws and anterior reconstruction comprising kyphoplasty when possible or corpectomy in cases of excessive damage to the vertebral body. Back pain, traumatic local and regional kyphosis, and Beck's Index were collected pre- and postoperatively, and at 3-, 6-, and 12-month follow-ups. RESULTS Mean follow-up time was 13.4 months. Significant reductions in back pain (p<0.001) and local (p<0.001) and regional kyphosis (p=0.006) were found at the 6-month follow-up (alpha risk level <0.05). Beck's Index was also significantly increased, indicating good restoration of the anterior vertebral height. By the final follow-up, no screws had fallen/pulled out. There were no infectious or neurological complications. CONCLUSIONS Percutaneous cement-enhanced fixation for pathological fractures has proven a safe and efficient technique in our experience, enabling weak patients to rapidly become ambulatory again without complications. Further follow-up of the patients is necessary to assess the long-term effects of this technique and the continued quality of life of our patients.

A practical guide for planning pelvic bone percutaneous interventions (biopsy, tumour ablation and cementoplasty). Insights Imaging 2018; 9:275-285. [PMID: 29564836 PMCID: PMC5991000 DOI: 10.1007/s13244-018-0600-y] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2017] [Revised: 01/12/2018] [Accepted: 01/19/2018] [Indexed: 12/24/2022] Open
Abstract
Percutaneous approaches for pelvic bone procedures (bone biopsies, tumour ablation and cementoplasty) are multiple and less well systematised than for the spine or extremities. Among the different imaging techniques that can be used for guidance, computed tomography (CT) scan is the modality of choice because of the complex pelvic anatomy. In specific cases, such as cementoplasty where real-time evaluation is a determinant, a combination of CT and fluoroscopy is highly recommended. The objective of this article is to propose a systematic approach for image-guided pelvic bone procedures, as well as to provide some technical tips. We illustrate the article with multiple examples, and diagrams of the approaches and important structures to avoid to perform these procedures safely. TEACHING POINTS • Pelvic bone procedures are safe to perform if anatomical landmarks are recognised. • The safest approach varies depending on the pelvic level. • CT is the modality of choice for guiding pelvic percutaneous procedures. • Fluoroscopy is recommended when real-time monitoring is mandatory. • MRI can also be used for guiding pelvic percutaneous procedures.

Abstract
Objective The diagnosis of insufficiency fractures of the sacrum in an elder population increases annually. Fractures show very different morphology. We aimed to classify sacral insufficiency fractures according to the position of cortical break and possible need for intervention. Methods Between January 1, 2008 and December 31, 2014, all patients with a proven fracture of the sacrum following a low-energy or an even unnoticed trauma were prospectively registered : 117 females and 13 males. All patients had a computer tomography of the pelvic ring, two patients had a magnetic resonance imaging additionally : localization and involvement of the fracture lines into the sacroiliac joint, neural foramina or the spinal canal were identified. Results Patients were aged between 46 and 98 years (mean, 79.8 years). Seventy-seven patients had an unilateral fracture of the sacral ala, 41 bilateral ala fractures and 12 patients showed a fracture of the sacral corpus : a total of 171 fractures were analyzed. The first group A included fractures of the sacral ala which were assessed to have no or less mechanical importance (n=53) : fractures with no cortical disruption (“bone bruise”) (A1; n=2), cortical deformation of the anterior cortical bone (A2; n=4), and fracture of the anterolateral rim of ala (A3; n=47). Complete fractures of the sacral ala (B; n=106) : parallel to the sacroiliac joint (B1; n=63), into the sacroiliac joint (B2; n=19), and involvement of the sacral foramina respectively the spinal canal (B3; n=24). Central fractures involving the sacral corpus (C; n=12) : fracture limited to the corpus or finishing into one ala (C1; n=3), unidirectional including the neural foramina or the spinal canal or both (C2; n=2), and horizontal fractures of the corpus with bilateral sagittal completion (C3; n=8). Sixty-eight fractures proceeded into the sacroiliac joint, 34 fractures showed an injury of foramina or canal. Conclusion The new classification allowes the differentiation of fractures of less mechanical importance and a risk assessment for possible polymethyl methacrylate leaks during sacroplasty in the direction of the neurological structures. In addition, identification of instable fractures in need for laminectomy and surgical stabilization is possible.

Abstract
BACKGROUND Die-punch intra-articular fractures of the distal radius raise surgical challenges. The residual articular step-off must be less than 1mm to prevent the development of radio-carpal osteoarthritis. The objectives of this cadaver study were to evaluate whether cementoplasty was effective in reducing die-punch fractures and to determine whether this technique was feasible as an arthroscopic procedure. HYPOTHESIS Cementoplasty performed as an arthroscopic procedure is effective in treating die-punch fractures. MATERIAL AND METHODS Eleven cadaver forearms collected at a laboratory were studied. In each, a depressed fracture of the lunate fossa of the radial articular surface was created using a Tinius Olsen H25K-S compression test machine. A Kyphon XPander® balloon (Medtronic) was used to lift the depressed area, and calcium-phosphate cement was then injected to stabilise the reduction. Cementoplasty under arthroscopic guidance was performed on an additional forearm. RESULTS Computed tomography of the wrists after fracture induction showed a mean depression of 4.66mm (range, 4.01-5.25mm). Arthroscopic cementoplasty proved feasible with the arthroscope inserted through the 3-4 radio-carpal portal. Positioning the balloon under the depressed area ensured satisfactory reduction and allowed the injection of cement. DISCUSSION Cementoplasty may be useful for the treatment of die-punch fractures. Additional indications may be other types of distal radius fractures with articular surface depression. LEVEL OF EVIDENCE IV, cadaver study.

Malunion of post-traumatic thoracolumbar fractures. Orthop Traumatol Surg Res 2018; 104:S55-S62.

Abstract
Thoracolumbar malunion is the result of loss of correction, insufficient correction or even no correction (both in the frontal and sagittal planes) of a thoracolumbar fracture. The main causes are incorrect assessment of the fracture's complexity (burst fracture), its potential progression to kyphosis and associated disc or ligament damage. It can also be the result of a poorly conducted initial treatment. The types of malunion have changed over the years because of the introduction of vertebroplasty and kyphoplasty. The malunion can be well tolerated if there is only a moderate deformity. However, the functional and pain-related limitations can be severe with large deformities. Functional limitation is mainly related to sagittal imbalance, but also to sequelae associated with the injury in various ways (non-union, disc degeneration, spinal cord compression, syringomyelia, etc.). The deformity and its consequences are evaluated globally using full-body standing radiographs (EOS), CT scan and MRI. Comparison of MRI images taken in a lying position to weight bearing views or even dynamic ones is an additional means to evaluate whether the lesions are reducible. Differences in spine morphology and compensatory mechanisms to combat the sagittal imbalance induced by the deformity must also be analyzed. These provide more complete information about the consequences of the malunion and help to establish the best corrective strategy. These compensatory mechanisms consist of accentuation of lumbar lordosis along with reduction of thoracic kyphosis. As a last resort, the pelvis and femur contribute to this compensation when there is a large deformity or a stiff spine due to preexisting osteoarthritis. Treatment strategies are fairly well standardized. When the deformity is reducible, a two-stage surgery is indicated. When the deformity is not reducible, posterior transpedicular closed wedge osteotomy is the gold standard. Nevertheless, the best way to treat thoracolumbar malunion is to prevent it.

Abstract
INTRODUCTION Percutaneous image-guided ablation is an emerging minimally invasive therapy for patients with metastatic bone disease for whom radiation therapy is ineffective or contraindicated. The purpose of this study was to examine the safety and efficacy of percutaneous ablation in achieving pain palliation and local tumor control of osseous metastases from non-small cell lung cancer (NSCLC). METHODS A retrospective review was performed of 76 musculoskeletal metastases in 45 patients treated with percutaneous ablation. 63% (48/76) were treated with radiofrequency ablation (RFA), 35% (27/76) with cryoablation, and 1.3% (1/76) with microwave ablation (MWA). In 70% (53/76) of cases, associated cementoplasty was performed. Primary outcomes measured were pre- and post-procedure pain scores 4 weeks after treatment and local tumor control at 3-, 6-, and 12-month follow-up. RESULTS Mean age of the cohort was 63.6 ± 9.5 years. Median tumor diameter was 3.60 cm (range 1.0-10.0 cm). Mean and median pain scores before treatment were 7.5 ± 2.3 and 8.0, respectively. Post-procedure, patients reported significantly decreased pain scores at 4 weeks (mean, 3.7 ± 3.5; median, 3.0; p < 0.00001). Radiographic local tumor control rates were 83% (35/42) at 3 months, 77% (23/30) at 6 months, and 68% (17/25) at 12 months after treatment. The overall complication rate was 2.6% (2/76). CONCLUSION Percutaneous tumor ablation is a well-tolerated, minimally invasive procedure associated with improving pain palliation and achieving local tumor control of osseous metastases from NSCLC.

Abstract
OBJECTIVE To evaluate the feasibility and effectiveness of computed tomography (CT)-guided percutaneous screw fixation plus cementoplasty (PSFPC), for either treatment of painful metastatic fractures or prevention of pathological fractures, in patients who are not candidates for surgical stabilization. MATERIALS AND METHODS Twenty-seven patients with 34 metastatic bone lesions underwent CT-guided PSFPC. Bone metastases were located in the vertebral column, femur, and pelvis. The primary end point was the evaluation of feasibility and complications of the procedure, in addition to the length of hospital stay. Pain severity was estimated before treatment and 1 and 6 months after the procedure using the visual analog scale (VAS). Functional outcome was assessed by improved patient walking ability. RESULTS All sessions were completed and well tolerated. There were no complications related to either incorrect positioning of the screws during bone fixation or leakage of cement. All patients were able to walk within 6 h after the procedure and the average length of hospital stay was 2 days. The mean VAS score decreased from 7.1 (range, 4-9) before treatment to 1.6 (range, 0-6), 1 month after treatment, and to 1.4 (range 0-6) 6 months after treatment. Neither loosening of the screws nor additional bone fractures occurred during a median follow-up of 6 months. CONCLUSIONS Our results suggest that PSFPC might be a safe and effective procedure that allows the stabilization of the fracture and the prevention of pathological fractures with significant pain relief and good recovery of walking ability, although further studies are required to confirm this preliminary experience.

Abstract
Osteoporotic fractures of the sacrum usually involve the sacral ala and can be managed with percutaneous cementoplasty if conservative therapy failed to achieve bone consolidation. On the other hand, isolated transverse fractures of the lowest sacrum are more rare, with little literature focusing on their management in the osteoporotic population. If pseudoarthrosis occurs in this location, sacroplasty is not an optimal therapeutic option because of the poor biomechanical resistance of cement to multi-directional stresses. Hence, we report two cases of chronic unhealed transverse fractures of the lowest sacrum successfully managed with percutaneous image-guided screw fixation augmented with cement injection. At last follow-up available, both patients experienced complete pain relief, without evidences of failure of the osteosynthesis on CT-scan controls.

Abstract
Bone metastases are a common finding in oncology. They often induce pain but also fractures which impair quality of life, especially when involving weight-bearing bones. Percutaneous image-guided consolidation techniques play a major role for the management of bone metastases. Cementoplasty aims to stabilize bone and control pain by injecting acrylic cement into a weakened bone. This minimally invasive technique has proven its efficacy for bones submitted to compression forces: vertebra, acetabular roof, and condyles. However, long bone diaphysis should be treated with caution due to lower resistance of the cement subject to torsional forces. The recent improvements of navigation systems allow percutaneous image-guided screw fixation without requiring open surgery. This fast-track procedure avoids postponing introduction of systemic therapies. If needed, cementoplasty can be combined with screw insertion to ensure better anchoring in major osteolysis. Interventional radiology bone consolidation techniques increase the therapeutic field in oncology. A multidisciplinary approach remains mandatory to select the best indications.

Abstract
Kienböck disease typically presents with wrist pain, swelling, restricted range of motion, and difficulty in performing activities of daily living. Because the etiology and evolution of disease remain unclear, broad ranges of treatments have been designed. Percutaneous cementoplasty is expanding its role for managing painful bone metastases outside the spine. We can draw a parallel between lytic tumoral lesions and Kienbock's disease. Increasing the strength and rigidity of lunate with cementoplasty can prevent it from collapse, relieve the symptoms associated with the process of avascular necrosis, and increase the wrist range of motion. We report the case of 30-year-old man with a painful stage IIIA Kienböck disease who underwent percutaneous cementoplasty and experienced immediate effective pain relief and recovery of wrist mobility.

Abstract
OBJECTIVE To evaluate low-pressure bone stenting combined with cementoplasty in extensive lytic lesions. METHODS A single-centre study involving four consecutive patients (four women) with extensive lytic tumours was performed. The average age was 65 years. Surgical treatment was not indicated or not wished for by the patients. Institutional review board approval and informed consent were obtained. Percutaneous consolidation was performed by an interventional radiologist under fluoroscopy guidance. Follow-up was assessed using the visual analogue scale (VAS). RESULTS Under general (n = 2) or local (n = 2) anaesthesia, five 11-gauge bone biopsy needles were advanced in four lesions. Five auto-expandable uncovered stents (10-14 mm diameter and 40-60 mm long) were inserted. In all cases, bone cement was successfully placed into the tumours. The volume of cement that was injected through the cannulas into the stents was 5-10 mL. Using VAS, pain decreased from more than 9/10 preoperatively to less than 2/10 after the procedure for all patients (p < 0.05). No complications occurred during the follow-up (8-19 months). CONCLUSION This study suggests that cementoplasty combined with low-pressure bone stenting could allow effective bone stabilization resulting in pain relief. KEY POINTS • Low-pressure bone stenting is possible. • This technique improves cement injection control. • The procedure allows effective bone stabilization resulting in pain relief.

Abstract
PURPOSE To retrospectively evaluate the outcome of patients who underwent radiological percutaneous osteosynthesis and cementoplasty (RPOC) for stabilization of malignant pathological fracture of the proximal femur. MATERIALS AND METHODS The clinical files of 12 patients who underwent RPOC for stabilization of malignant pathological fracture of the proximal femur were reviewed. There were 9 men and 3 women with a mean age of 56 years±13 (SD) (range: 35-82 years). All patients had metastases of proximal femur and a high fracture risk (Mirels score≥8) and were not eligible for surgical stabilization. The primary endpoint was the occurrence of a fracture after RPOC. Secondary endpoints were the procedure time, early complications of RPOC, pain reduction as assessed using a visual analog scale (VAS) and duration of hospital stay. RESULTS No patients treated with RPOC had a fracture during a mean follow-up time of 382 days±274 (SD) (range: 11-815 days). RPOC was performed under general (n=10) or locoregional (n=2) anesthesia. The average duration of the procedure was 95min±17 (SD) (range: 73-121min). The technical success rate was 100%. All patients were able to walk on the day following RPOC. The average duration of hospital stay was 4days ±3 (SD) (range: 2-10 days). No major complication occurred. One patient complained of hypoesthesia in the lateral thigh. For symptomatic patients (n=7), VAS score decreased from 6.8±1.2 (SD) (range: 5-9) before treatment, to 2.3±1.1 (SD) (range: 1-4) one month later. CONCLUSION Preventive RPOC for pathological fracture of the proximal femur is a reliable alternative for cancer patients who are not candidates for surgical stabilization. Studies involving more patients are needed to confirm our preliminary experience.

Colon cancer metastasis to the sternum: palliative treatment with radiofrequency ablation and cement injection. Radiol Case Rep 2016; 11:357-360. [PMID: 27920861 PMCID: PMC5128385 DOI: 10.1016/j.radcr.2016.09.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2016] [Revised: 09/12/2016] [Accepted: 09/15/2016] [Indexed: 11/25/2022] Open
Abstract
Colon cancer metastasis to bone is extremely rare and has devastating consequences on patients' quality of life. Furthermore, radiofrequency ablation in conjunction with cementoplasty to nonweight bearing, flat bones has not been widely reported as palliative treatment for pain as a result of bone metastasis. Here, we present a case of a 47-year-old man who developed a sternal metastasis from an invasive adenocarcinoma of the colon originally diagnosed several years prior. The pain from the metastasis was originally treated with external beam radiation therapy, but after 6 weeks of continuous pain, it was retreated using radiofrequency ablation in conjunction with cementoplasty.

Abstract
OBJECTIVES To study the various local treatments available for thyroid cancer metastases, investigate techniques and assess their advantages and limitations and roles in the overall treatment strategy for metastatic disease. RESULTS We investigated metastases surgery, external radiation therapy, embolization, chemoembolization, cementoplasty, radiofrequency ablation and cryotherapy, describing techniques, advantages and drawbacks and possible complications. Indications were reviewed according to metastases location, and the roles of the various techniques are discussed in the overall treatment strategy for thyroid cancer metastases. Despite the advent of new targeted therapies, local treatment still has an important role to play: either palliative or, in oligometastatic involvement, curative. Even in extensive disease, it may allow postponement of tyrosine kinase inhibitor therapy, which, once initiated, has to be continued life-long, is expensive and is not free of side-effects.

Combination acetabular radiofrequency ablation and cementoplasty using a navigational radiofrequency ablation device and ultrahigh viscosity cement: technical note. Skeletal Radiol 2016; 45:401-5. [PMID: 26408315 DOI: 10.1007/s00256-015-2263-9] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2015] [Revised: 08/20/2015] [Accepted: 09/06/2015] [Indexed: 02/02/2023]
Abstract
BACKGROUND Percutaneous radiofrequency ablation and cementoplasty is an alternative palliative therapy for painful metastases involving axial load-bearing bones. This technical report describes the use of a navigational radiofrequency probe to ablate acetabular metastases from an anterior approach followed by instillation of ultrahigh viscosity cement under CT-fluoroscopic guidance. MATERIALS AND METHODS The tumor ablation databases of two institutions were retrospectively reviewed to identify patients who underwent combination acetabular radiofrequency ablation and cementoplasty using the STAR Tumor Ablation and StabiliT Vertebral Augmentation Systems (DFINE; San Jose, CA). Pre-procedure acetabular tumor volume was measured on cross-sectional imaging. Pre- and post-procedure pain scores were measured using the Numeric Rating Scale (10-point scale) and compared. Partial pain improvement was categorically defined as ≥ 2-point pain score reduction. Patients were evaluated for evidence of immediate complications. Electronic medical records were reviewed for evidence of delayed complications. RESULTS During the study period, 12 patients with acetabular metastases were treated. The median tumor volume was 54.3 mL (range, 28.3-109.8 mL). Pre- and post-procedure pain scores were obtained from 92% (11/12) of the cohort. The median pre-procedure pain score was 8 (range, 3-10). Post-procedure pain scores were obtained 7 days (82%; 9/11), 11 days (9.1%; 1/11) or 21 days (9.1%; 1/11) after treatment. The median post-treatment pain score was 3 (range, 1-8), a statistically significant difference compared with pre-treatment (P = 0.002). Categorically, 73% (8/11) of patients reported partial pain relief after treatment. No immediate symptomatic complications occurred. Three patients (25%; 3/12) were discharged to hospice within 1 week of treatment. No delayed complications occurred in the remaining 75% (9/12) of patients during median clinical follow-up of 62 days (range, 14-178 days). CONCLUSIONS Palliative percutaneous acetabular radiofrequency ablation and cementoplasty can be feasibly performed from an anterior approach using a navigational ablation probe and ultrahigh viscosity cement instilled under CT-fluoroscopic guidance.

Over ten years of single-institution experience in percutaneous image-guided treatment of bone metastases from differentiated thyroid cancer. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2015; 41:1247-55. [PMID: 26136221 DOI: 10.1016/j.ejso.2015.06.005] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2015] [Revised: 05/17/2015] [Accepted: 06/10/2015] [Indexed: 11/26/2022]
Abstract
OBJECTIVE Percutaneous image-guided treatments (PIGT) are performed by interventional radiologists with a minimally invasive approach. Currently, very little published data on their outcomes are available and conclusions regarding their application are cautious. The aim of the present study was to review our experience in PIGT of bone metastases from thyroid cancer. MATERIALS AND METHODS Institutional databases were reviewed to identify patients with differentiated thyroid cancer and bone metastases who received PIGT between October 2001 and April 2014. Complications, local evolution of the treated lesions, and overall survival (OS) were investigated. RESULTS Twenty-five patients (12 male, 13 female) underwent 49 PIGT sessions consisting of cementoplasty (77.5%), cryoablation (14.3%) or radiofrequency ablation (8.2%). Most of the treated lesions (50/54, 92.6%) were symptomatic at the time of PIGT. Median follow-up after PIGT was 4.6 years. Local complete remission rate was 55.6%. Two complications (one major and one minor) were noted, but none of these were consistent with fractures or nervous system injuries. OS after PIGT was 71.6%, 66.8% and 60.1% at 1, 2 and 3 years, respectively. A difference in survival was observed between patients with metastatic bone involvement only at the time of first PIGT compared to those with multi-organ involvement (P = 0.03). CONCLUSIONS Patients with bone metastases from differentiated thyroid cancer may benefit from PIGT. Although patients are usually referred for PIGT due to their symptomatic status, a more relevant "curative" role may exist for PIGT. Further prospective studies are needed to confirm this perception.

Biomechanical behavior of MRI-signal-inducing bone cements after vertebroplasty in osteoporotic vertebral bodies: An experimental cadaver study. Clin Biomech (Bristol, Avon) 2014; 29:571-6. [PMID: 24703828 DOI: 10.1016/j.clinbiomech.2014.03.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2013] [Revised: 03/04/2014] [Accepted: 03/10/2014] [Indexed: 02/07/2023]
Abstract
BACKGROUND Conventional water-free polymethylmethacrylate cements are not MRI visible due to the lack of free protons. A new MRI-visible bone cement was developed through the addition of a contrast agent and either a saline solution or a hydroxyapatite (Wichlas et al., 2010). The purposes of the study were to examine the influence of the two MRI-signal-inducing cements on the biomechanical behavior of cadaveric osteoporotic vertebral bodies after vertebroplasty and to compare the performance of the cements with conventional polymethylmethacrylate cement. METHODS Three different cements were used: standard polymethylmethacrylate cement and two modified MRI-signal-inducing cements that were mixed with either a 0.9% saline solution or a hydroxyapatite. The modulus of elasticity for the standard polymethylmethacrylate cement was 2040MPa, and the moduli for the MRI-signal-inducing cements that were mixed with a 0.9% saline solution and a hydroxyapatite were 1477 and 1225MPa, respectively. The lumbar vertebral bodies from nine osteoporotic spines (mean age=87 years, range=78-99 years) of female cadavers were examined. Three groups were formed: polymethylmethacrylate cement with saline solution (n=14), polymethylmethacrylate cement with hydroxyapatite (n=12) and polymethylmethacrylate cement (n=13). The vertebral bodies were biomechanically tested before and after vertebroplasty. Stiffness was chosen as the primary biomechanical parameter. FINDINGS The vertebral body stiffness was nearly two-fold greater after vertebroplasty, and this increase was statistically significant for every group. All the groups had similar vertebral body stiffness value before and after the vertebroplasty. The UNIANOVA test for multivariate analysis of variance showed no influence of lumbar level, injected cement volume and initial vertebral body stiffness. INTERPRETATION The elastic moduli of the cements appear to exert little influence on the biomechanical values when the cement is in the vertebral body. Based on the direct comparison with the classic polymethylmethacrylate cement, we believe that the implementation of such cements for MRI-guided vertebroplasties is feasible.

Abstract
We reviewed the outcome of patients who had been treated operatively for symptomatic peri-acetabular metastases and present an algorithm to guide treatment. The records of 81 patients who had been treated operatively for symptomatic peri-acetabular metastases between 1987 and 2010 were identified. There were 27 men and 54 women with a mean age of 61 years (15 to 87). The diagnosis, size of lesion, degree of pelvic continuity, type of reconstruction, World Health Organization performance status, survival time, pain, mobility and complications including implant failure were recorded in each case. The overall patient survivorship at five years was 5%. The longest lived patient survived 16 years from the date of diagnosis. The mean survival was 23 months (< 1 to 16 years) and the median was 15 months. At follow-up 14 patients remained alive. Two cementoplasties failed because of local disease progression. Three Harrington rods broke: one patient needed a subsequent Girdlestone procedure. One 'ice-cream cone' prosthesis dislocated and was subsequently revised without further problems. We recommend the 'ice-cream cone' for pelvic discontinuity and Harrington rod reconstruction for severe bone loss. Smaller defects can be safely managed using standard revision hip techniques.
