Induced-membrane technique for lower limb reconstruction after malignant bone tumour resection in paediatric patients: Complication and re-operation rates. Orthop Traumatol Surg Res 2024; 110:103875. [PMID: 38556207 DOI: 10.1016/j.otsr.2024.103875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 06/29/2023] [Accepted: 07/11/2023] [Indexed: 04/02/2024]
Abstract
BACKGROUND The objective of this study was to assess the complication and re-operation rates, evaluate the risk of non-union, and describe the functional outcomes at last follow-up in children and adolescents after lower-limb malignant tumour resection and reconstruction using the induced-membrane technique. HYPOTHESIS Weight-bearing resumption 6 weeks after the second stage of the induced-membrane procedure promotes bone healing. MATERIAL AND METHODS The study included 13 patients (9 with osteosarcoma, 3 with Ewing's sarcomas, and 1 with alveolar sarcoma) managed between 2000 and 2020 by oncological femoral or tibial resection followed, at a distance from adjuvant chemotherapy, by reconstruction using the induced-membrane technique. Non-union was the primary outcome measure and the MusculoSkeletal Tumor Society (MSTS) lower-limb functional score was the secondary outcome measure. Mean follow-up was 6.1 years (range, 2.0-12.7). At last follow-up, mean age was 18.1 years (range, 11.0-26.0) and the mean MSTS score was 66.6% (37.0-93.0%). RESULTS After the second reconstruction stage, 8 complications developed in 6 patients (46%). Either a complication or limb-length inequality required 12 re-operations in 8 patients (61.5%). Non-union occurred after reconstruction in 5 (38.5%) patients. Early resumption of 50% weight-bearing 6 weeks after reconstruction was associated with bone healing (p=0.02). CONCLUSION The non-union rate was 38.5%. Partial, 50% weight-bearing with two elbow crutches and an orthosis, if allowed by construct stability, may promote bone healing. LEVEL OF EVIDENCE IV.

Abstract
BACKGROUND Most lower extremity defects and minor bone defect wounds requiring a free flap are treatable with soft-tissue flaps, whereas large bone defect wounds are treated with bone-based flaps. This study aimed to compare bone-based and soft-tissue-free flaps in terms of operative procedures and postoperative complications, including long-term outcomes of lower extremity reconstruction. METHODS This two-center retrospective cohort study collected data from all lower-extremity reconstructions with free flaps performed between March 2014 and February 2022; the level of evidence is considered to be therapeutic level III. We investigated the operative procedure and postoperative complications classified as being related to either bone-based or soft-tissue flaps. The data were further classified into the trauma and non-trauma groups and the long-term postoperative outcomes of patients who were followed up for ≥12 months were analyzed. RESULTS A total of 122 free flaps were included: 29 bone-based flaps (1 scapular and 28 fibular flaps) and 93 soft-tissue flaps (22 muscle-based and 71 fasciocutaneous flaps). There was no significant difference in postoperative complications, including long-term outcomes, between the free flap types, regardless of etiology. Vein grafts were used more often for bone-based flaps than for soft-tissue flaps (20.7% vs. 7.5%; p = 0.045). The donor veins of bone-based flaps were more often anastomosed to superficial veins than were those of soft-tissue flaps (37.9% vs. 10.8%; p < 0.001). CONCLUSIONS Using bone-based free flaps resulted in no significant differences in postoperative complications, including long-term outcomes, despite involving more complicated operative procedures than soft-tissue flaps. Thus, the use of vein grafts and anastomosis to the superficial venous system of the vascularized fibula graft may help avoid flap-related complications in bone-based free flaps.

J Hand Surg Am 2023; 48:984-992. [PMID: 37542493 DOI: 10.1016/j.jhsa.2023.06.008] [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: 10/23/2022] [Revised: 05/15/2023] [Accepted: 06/23/2023] [Indexed: 08/07/2023]
Abstract
PURPOSE Vascularized bone grafting (VBG) has been described as the technique of choice for larger bone defects in bone reconstruction, yielding excellent results at the traditional threshold of 6 cm as described in the literature. However, we hypothesize that the 2-stage Masquelet technique provides equivalent union rates for upper-extremity bone defects regardless of size, while having no increase in the rate of patient complications. METHODS A systematic literature review was conducted using PubMed and Scopus for outcomes after VBG and the Masquelet technique for upper-extremity bone defects of the humerus, radius, ulna, metacarpal, or phalanx (carpal defects were excluded). A meta-analysis was performed to compare outcomes following VBG and the Masquelet technique at varying defect sizes. RESULTS There were 77 VBG (295 patients) and 25 Masquelet (119 patients) studies that met inclusion criteria. Patients undergoing the Masquelet technique had defect sizes ranging from 0-15 cm (average 4.5 cm), while patients undergoing VBG had defect sizes ranging from 0-24 cm (average 5.9 cm). The union rate for Masquelet patients was 94.1% with an average time to union of 5.8 months, compared to 94.9% and 4.4 months, respectively, for VBG patients. We did not identify a defect size threshold at which VBG demonstrated a significantly higher union rate. No statistically significant difference was found in union rates between techniques when using multivariable logistic regression analysis. CONCLUSION There was no statistically significant difference in union rates between VBG and the Masquelet technique in upper-extremity bone defects regardless of defect size. Surgeons may consider the Masquelet technique as an alternative to VBG in large bone defects of the upper extremity. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV.

Abstract
AIMS The reconstruction of proximal humeral defects resulting from tumor resection is challenging. The purpose of this work was to retrospectively study the functional outcomes in patients with large bone defects after the resection of proximal humeral tumors. METHODS We performed a retrospective analysis of 49 patients with malignant or aggressive benign tumors in the proximal humerus at our institution between 2010 and 2021. Forty-nine patients were included in the study (prosthetic replacement, n = 27; shoulder arthrodesis, n = 22). The mean follow-up was 52.8 months (range, 14-129 months). The factors evaluated included the Musculoskeletal Tumor Society (MSTS) functional score, Constant Murley Score (CMS), and complications. RESULTS Of the 49 patients enrolled in the study, 35 were disease-free by the time of the latest follow-up, and 14 died because of the disease. Adjuvant therapies and medical comorbidities were similar between the two groups. Osteosarcoma was the most common abnormality among all the patients. The mean MSTS scores for surviving patients in the prosthesis and arthrodesis groups were 57.4% and 80.9%, respectively. The mean CMS score for the surviving patients in the prosthesis group was 43.47, and it was 61.44 for arthrodesis cases. Patients with shoulder arthrodesis demonstrated evidence of bony union at a mean of 4.5 months. CONCLUSIONS Shoulder arthrodesis is a reliable reconstructive procedure in patients with large bone defects after the resection of proximal humeral tumors for pediatric osteosarcoma patients. Moreover, prosthetic replacement with anatomical implants results in poor function in older metastasis patients with large bone defects and resection of the deltoid muscle.

Abstract
Bone defects that are congenital or the result of infection, malignancy, or trauma represent a challenge to the global healthcare system. To address this issue, multiple research groups have been developing novel cell sheet technology (CST)-based approaches to promote bone regeneration. These methods hold promise for use in regenerative medicine because they preserve cell-cell contacts, cell-extracellular matrix interactions, and the protein makeup of cell membranes. This review introduces the concept and preparation system of the cell sheet (CS), explores the application of CST in bone regeneration, highlights the current states of the bone regeneration via CST, and offers perspectives on the challenges and future research direction of translating current knowledge from the lab to the clinic.

Hip-Preserved Reconstruction Using a Customized Cementless Intercalary Endoprosthesis With an Intra-Neck Curved Stem in Patients With an Ultrashort Proximal Femur: Midterm Follow-Up Outcomes. Front Bioeng Biotechnol 2022; 10:795485. [PMID: 35295648 PMCID: PMC8918842 DOI: 10.3389/fbioe.2022.795485] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2021] [Accepted: 01/21/2022] [Indexed: 12/24/2022] Open
Abstract
Background: Hemiarthroplasty is widely used for proximal femoral reconstruction after tumor resection. However, complications of hemiarthroplasty include infection, hip dislocation, and acetabular wear. This study aimed to: (1) evaluate the reliability and validity of a customized cementless intercalary endoprosthesis (CCIE) with an intra-neck curved stem (INCS) to reconstruct femoral diaphyseal defects with an ultrashort proximal femur (UPF); (2) assess the lower extremity function after reconstruction with this endoprosthesis; and (3) identify the postoperative complications associated with the use of this endoprosthesis. Methods: Between October 2015 and May 2019, 13 patients underwent reconstruction with a CCIE with an INCS. The distance from the center of the femoral head to the midline of the body and the apex of the acetabulum was measured preoperatively. Additionally, the distance from the tip of the INCS to the midline of the body and the apex of the acetabulum was measured postoperatively. The femoral neck–shaft angle was also measured pre- and postoperatively. After an average follow-up duration of 46 months, the radiological outcomes of the CCIE with an INCS were analyzed. Function was evaluated with the Musculoskeletal Tumor Society (MSTS) score. Pain was measured using a paper visual analog scale (VAS) pre- and postoperatively, and complications were recorded. Results: Compared with our preoperative design, we found no significant difference in the postoperative distance from the tip of the INCS to the body midline (p = 0.187) and the apex of the acetabulum (p = 0.159), or in the postoperative femoral neck–shaft angle (p = 0.793). Thus, the INCS positions were deemed accurate. The average MSTS score was 26 (range: 24–28), and the VAS score was significantly decreased postoperatively compared with preoperatively (p < 0.0001). No patients developed aseptic loosening, infection, periprosthetic fracture, or prosthetic fracture as of the last follow-up. Conclusion: The CCIE with an INCS was a valid and reliable method for reconstructing femoral diaphyseal defects with a UPF following malignant tumor resection. Postoperative lower extremity function was acceptable, with an appropriate individualized rehabilitation program, and the incidence of complications was low.

Abstract
Large segmental bone defects due to major trauma constitute a major challenge for the orthopaedic surgeon, especially when combined with poor or lost soft tissue envelope. Vascularized fibular transfer is considered as the gold standard for the reconstruction of such defects of the extremities due to its predictable vascular pedicle, long cylindrical shape, and tendency to hypertrophy, and resistance to infection. Vascularized bone grafts remain viable throughout the healing period and are capable of inducing rapid graft union without prolonged creeping substitution, osteogenesis and hypertrophy at the reconstruction site, and fight with infection. The fibular graft can be transferred solely, or as a composite flap including muscle, subcutaneous tissue, skin and even a nerve segment in order to reconstruct both bone and soft tissue components of the injury at single stage operation. Such a reconstruction can even be performed in the presence of local infection, since vascularized bone and adjacent soft tissue components enhances the blood flow at the traumatized zone, allowing for the delivery of antibiotics and immune components to the infection site. In an effort to preserve growth potential in pediatric patients; the fibular head and proximal growth plate can be included to the graft. This practice also enables to reconstruct the articular ends of various bones, including distal radius and proximal ulna. Apart from defect reconstruction, vascularized fibular grafts also proved to be a reliable in treating atrophic nonunions, reconstruction of osteomyelitic bone segments. These grafts are superior to alternative reconstructive techniques, as bone grafts with intrinsic blood supply lead to higher success rates in reconstruction and accelerate the repair process at the injury site in cases where blood supply to the injury zone is defective, poor soft tissue envelope, and local infection at the trauma zone.

Abstract
AIMS Orthopaedic and reconstructive surgeons are faced with large defects after the resection of malignant tumours of the sacrum. Spinopelvic reconstruction is advocated for resections above the level of the S1 neural foramina or involving the sacroiliac joint. Fixation may be augmented with either free vascularized fibular flaps (FVFs) or allograft fibular struts (AFSs) in a cathedral style. However, there are no studies comparing these reconstructive techniques. METHODS We reviewed 44 patients (23 female, 21 male) with a mean age of 40 years (SD 17), who underwent en bloc sacrectomy for a malignant tumour of the sacrum with a reconstruction using a total (n = 20), subtotal (n = 2), or hemicathedral (n = 25) technique. The reconstructions were supplemented with a FVF in 25 patients (57%) and an AFS in 19 patients (43%). The mean length of the strut graft was 13 cm (SD 4). The mean follow-up was seven years (SD 5). RESULTS There was no difference in the mean age, sex, length of graft, size of the tumour, or the proportion of patients with a history of treatment with radiotherapy in the two groups. Reconstruction using an AFS was associated with nonunion (odds ratio 7.464 (95% confidence interval (CI) 1.77 to 31.36); p = 0.007) and a significantly longer mean time to union (12 months (SD 3) vs eight (SD 3); p = 0.001) compared with a reconstruction using a FVF. Revision for a pseudoarthrosis was more likely to occur in the AFS group compared with the FVF group (hazard ratio 3.84 (95% CI 0.74 to 19.80); p = 0.109); however, this was not significant. Following the procedure, 32 patients (78%) were mobile with a mean Musculoskeletal Tumor Society Score 93 of 52% (SD 24%). There was a significantly higher mean score in patients reconstructed with a FVF compared with an AFS (62% vs 42%; p = 0.003). CONCLUSION Supplementation of spinopelvic reconstruction with a FVF was associated with a shorter time to union and a trend towards a reduced risk of hardware failure secondary to nonunion compared with reconstruction using an AFS. Spinopelvic fixation supplemented with a FVF is our preferred technique for reconstruction following resection of a sacral tumour. Cite this article: Bone Joint J 2021;103-B(8):1414-1420.

Abstract
Forearm sarcoma is rare in children. Here, we report three cases. One child presented undifferentiated soft-tissue sarcoma involving the ulna, another had Ewing's sarcoma of the ulna, and the third had Ewing's sarcoma of the proximal radius. In the first case, there were episodes of iterative aseptic nonunion, treated surgically. At last follow-up (respectively 11, 9 and 8 years postoperatively), the mean Musculoskeletal Tumor Society (MSTS) score was 80%, 90% and 77% respectively, and all cases were in remission. The induced membrane technique to reconstruct bone defect after sarcoma resection in children is a possible limb-salvage strategy.

Abstract
BACKGROUND The treatment of primary malignant bone tumours is interdisciplinary and individually adapted to the patient. Nowadays, limb salvage surgery is usually possible, and the subsequent reconstruction is carried out either by implantation of modular tumour megaprostheses or by biological reconstruction procedures. Special surgical and secondary complications have to be considered. OBJECTIVES Indication and explanation of various biological reconstruction procedures and presentation of specific peri- and postoperative complications. MATERIALS AND METHODS An adapted literature review and the contribution of our own therapy experiences and case studies for the presentation of biological reconstructions and their complication management was performed. RESULTS In biological reconstructions, autografts, allografts or a combination of autografts and allografts are used. Stabilization is achieved with screw and plate osteosyntheses. The most common secondary complications are pseudarthrosis, interponate fracture, graft necrosis and secondary malpositions. CONCLUSION In selected cases, particularly at the upper extremities and in dia- or metaphyseal tumour sites, biological reconstruction after extralesional tumor resection is the surgical therapy of choice. The rate of long-term revision interventions is significantly lower compared to modular tumour megaprostheses. Biological reconstructions and the treatment of specific complications have to be performed in specialized centres for musculoskeletal surgical oncology/tumor orthopedics.

Abstract
Background The optimal reconstructive method after diaphyseal malignant bone tumor resection remains controversial. This multicenter clinical study was designed to investigate the clinical value and complications of segmental prosthesis in the repair of diaphyseal defects. Methods We present 49 patients from three clinical centers treated with wide resection for primary or metastatic bone tumors involving the diaphysis of the femur, tibia, humerus, or ulna, followed by reconstruction using a modular intramedullary segmental prosthesis. Results Enrolled patients included 23 men and 26 women with a mean age of 63.3 years. Of these, seven patients had primary bone tumors and 42 patients had metastatic lesions. At the mean follow-up of 13.7 months, 17 patients were alive, 31 patients were deceased due to tumor progression, and one patient was dead of another reason. There were eight nononcologic complications (two with radial nerve injury, three with delayed incision healing, two with aseptic loosening in the proximal humerus prosthetic stem and one with structural failure) and three oncologic complications (three with primary tumor recurrence) among all patients. The incidence of complications in primary tumor patients (4/7, 57.1%) was higher than that in patients with metastatic tumors (7/42, 16.7%) (p = 0.036). Aseptic loosening and mechanical complications were not common for patients with primary tumors, although the reconstruction length difference was statistically significant (p = 0.023). No statistically significant differences were observed in limb function, while the mean musculoskeletal tumor society score was 21.2 in femora, 19.6 in humeri, and 17.8 in tibiae (p = 0.134). Conclusions Segmental prostheses represent an optional method for the reconstruction of diaphyseal defects in patients with limited life expectancy. Segmental prostheses in the humerus experienced more complications than those used to treat lesions in the femur.

J Clin Orthop Trauma 2019; 10:167-172. [PMID: 30705554 PMCID: PMC6349672 DOI: 10.1016/j.jcot.2017.09.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2017] [Revised: 08/18/2017] [Accepted: 09/07/2017] [Indexed: 11/30/2022] Open
Abstract
BACKGROUND Reconstruction of segmental bone defects following resection of bone sarcomas is a challenging procedure. Vascularised fibula grafts alone or in combination with extracorporeal radiotherapy and reimplantation of tumor bone have long been established as a method of reconstruction of such defects, with satisfying results. Prompted by paucity of data on Indian patients, we report our experience with vascularised fibula graft for patients undergoing limb salvage surgery for sarcomas of bone. MATERIAL AND METHODS A total of 25 patients underwent the procedure from December 2008 to December 2014. Femur was the commonest site and osteosarcoma was the commonest diagnosis. Intercalary resection was done in 19 patients and arthrodesis in 6 patients. Vascularised fibula was used in combination with extra corporeally irradiated bone in eight patients, and alone in 17 patients. RESULTS All but one limb could be salvaged, and all but three patients had united at final follow up. Combination of extracorporeal radiotherapy and reimplantation with vascularised fibula fared better than vascularised fibula alone in terms of time to union (9.6 months vs 12.2 months) and rate of graft related complications (14.2% vs 62.5%). CONCLUSION Reconstruction with VFG with or without ECRT has a good and predictable functional outcome. Though manageable with active intervention, complications were more commonly seen with vascularised fibula alone than a combination of the two techniques.
