Abstract
PURPOSE The purpose of this study was to describe and evaluate the use of a specially designed hollow trephine to create the entry point through the femoral condyle during retrograde interlocking intramedullary nailing for femoral fractures. METHODS From June 2019 to December 2021, we treated 11 patients (5 men, 6 women; mean age, 64 years; age range 40-77 years) with mid-distal femoral fractures by retrograde intramedullary femoral nailing using a self-designed hollow trephine for femoral condyle reaming and cancellous bone harvesting. The mode of all the nails is static. Patients were followed up at 1, 4, 8, and 12 weeks and for at least 6 months after surgery. The healing process and heterotopic ossification were evaluated by imaging. Partial weight bearing was permitted during the recovery period and complete weight bearing was permitted after clinical healing of the fracture displayed by X-ray. RESULTS The operation was successful in all patients. Over mean follow-up of 9.3 months (range, 6.0-12.0 months), all patients achieved clinical healing within three months. There were no complications such as knee joint infection, heterotopic ossification, knee joint adhesion and wedge effect. CONCLUSION The use of the hollow trephine during femoral retrograde intramedullary nailing helps avoid postoperative complications such as heterotopic ossification, knee joint adhesions, and wedge effect. It also facilitates bone graft harvesting.

Abstract
BACKGROUND Three-dimensional custom cages can be used to treat complex ankle and hindfoot pathology and bone loss with potentially better patient satisfaction and higher fusion rates than tibiotalocalcaneal (TTC) fusion alone or in combination with bulk femoral head allograft. Yet there is limited literature to support this procedure. The purpose of this study is to objectively quantify the clinical and radiologic outcomes of patients undergoing patient-specific 3D-printed custom cage implantation to fill large defects around the ankle joint region as part of a limb-salvaging TTC fusion. METHODS This is a retrospective review of 21 patients (mean age 59.3 years) who underwent custom cage implantation with a TTC retrograde fusion nail by a single surgeon for massive bone loss of the ankle and hindfoot. Patient charts were reviewed for pain and functional outcomes, complications, and various demographics, including number of previous surgeries to the ipsilateral ankle. Mean follow-up was 32 months. All 21 patients had preoperative and postoperative pain and function scores available for analysis. RESULTS A total of 20 (95.2%) of the 21 patients had their cage in situ at final follow-up. Overall, with the numbers available, visual analog scale (VAS) for pain, Foot and Ankle Ability Measure (FAAM) activities of daily living subscale, and the 12-Item Short Form Health Survey (SF-12) mental and physical health scores significantly improved from preoperative to final follow-up. However, when compared to the overall US population of age-matched 55- to 64-year-old individuals, patients still remained relatively disabled. There were 2 failures, one of which required amputation and the other was treated nonoperatively with bracing. CONCLUSION In conclusion, in this relatively small, single-surgeon series, we found that 3D-printed custom cage technology offered a viable option for complex TTC fusion procedures performed in the presence of significant bone loss, with good fusion rates, however relatively modest improvement in functional outcomes.

Abstract
SUMMARY The management of critical-sized bone and soft-tissue defects of the lower extremity poses unique challenge to reconstructive surgeons. The aim of this article is to present the authors' current orthoplastic approach for the management of extended (more than 6 cm) osteocutaneous defects of the lower extremity, based on a sequential combination of two stages: free flap for soft-tissue coverage and the Masquelet technique (first step) followed by reamer-irrigator-aspirator cancellous bone graft and definitive osteosynthesis (second step). This study was a single-center observational retrospective review of prospectively collected data. Adult patients (>18 years of age) with segmental bone loss of the lower extremity caused by acute trauma (Gustilo type IIIB fracture) or nonunion (septic/aseptic) who were treated with the free flap for soft-tissue coverage-Masquelet technique-reamer-irrigator-aspirator approach between January of 2017 and December of 2020 were included. Time of consolidation and early and late complications were recorded. A total of 11 patients (nine male patients and two female patients) with a mean age of 45.8 years were identified. The average bone gap length (standard deviation) was 87.3 (24.9) mm. An anterolateral thigh flap was harvested in all cases. The average duration of the first stage (i.e., time from antibiotic cement spacer placement and free flap to time of bone grafting) was 50.4 days (range, 40 to 62 days). Bone consolidation was achieved in all cases after an average period (standard deviation) of 20.4 (3.3) weeks, with acceptable functional outcomes. The free flap for soft-tissue coverage-Masquelet technique-reamer-irrigator-aspirator approach could be considered a viable option in patients with segmental critical-sized bone defects associated with a large soft-tissue deficit of the lower extremity. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, IV.

[PMID: 34640364 PMCID: PMC8509778 DOI: 10.3390/jcm10194347] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 09/19/2021] [Accepted: 09/23/2021] [Indexed: 12/11/2022] Open
Abstract
Autologous bone grafting is common in trauma and orthopaedic surgery. Both the Reamer Irrigator Aspirator (RIA) and Iliac Crest Bone Graft (ICBG) aim to obtain autologous bone graft. Although the process of harvesting a bone graft is considered simple, complications may occur. This study examined morbidity and pain at the donor site, blood loss, and iatrogenic fractures, comparing RIA and ICBG. The source of the autologous bone graft, the alternative graft sites, and the storage modalities of the harvested bone marrow were also evaluated. In May 2021, PubMed, Embase, Scopus, and Google Scholar were accessed, with no time constraints. RIA may produce greater blood loss, but with less morbidity and complications, making it a potential alternative source of bone grafting.

Abstract
BACKGROUND The biological waste collected during use of the Reamer/Irrigator/Aspirator (RIA; DePuy Synthes) has been described as an abundant source of bone progenitor cells with a comparable osteogenic gene profile to donor-matched iliac crest bone marrow (IC-BM). However, it is not clear whether these RIA-waste (RIA-W) cells are biologically fit. We aimed to evaluate the stress levels and functions of RIA-W progenitor cells. METHODS Reactive oxygen species (ROS) levels were tested in freshly collected bone progenitor cells (defined as CD45CD271 cells) using flow cytometry. ROS levels induced in these cells by hypoxia and/or oxidative stress as well as by an experimental simulation of the RIA procedure were also measured. Furthermore, the alkaline phosphatase (ALP) expression levels, proliferation, and senescence of culture-expanded RIA-W and IC-BM mesenchymal stromal cells (MSCs) were compared. RESULTS RIA-W and donor-matched IC-BM CD45CD271 cells were 97% and 98% viable, but the ROS levels were significantly higher for RIA-W cells than for IC-BM cells (p = 0.0020). Also, ROS induced by hypoxia, oxidative stress, and both were higher for RIA-W cells (p = 0.0312, 0.0156, and 0.0703, respectively). Dilution with saline solution, suction pressure, and irrigation reduced cell viability, with a positive correlation with the ROS level (p = 0.0035). The RIA-W and IC-BM colony-forming cells (average, 96,100 and 11,500, respectively) showed comparable ALP levels. Furthermore, culture-expanded RIA-W and IC-BM MSCs showed comparable ROS levels, ALP levels, susceptibility to death, and proliferation. CONCLUSIONS Although freshly collected RIA-W bone progenitor cells appeared to be transiently stressed, these cells were as viable as IC-BM cells and present in greater numbers. The proliferation and osteogenesis of both cell types were comparable. CLINICAL RELEVANCE The RIA waste bag contains bone progenitor cells with promising potential for regenerative applications, and should not be wasted.

Abstract
Bone grafts have been predominated used to treat bone defects, delayed union or non-union, and spinal fusion in orthopaedic clinically for a period of time, despite the emergency of synthetic bone graft substitutes. Nevertheless, the integration of allogeneic grafts and synthetic substitutes with host bone was found jeopardized in long-term follow-up studies. Hence, the enhancement of osteointegration of these grafts and substitutes with host bone is considerably important. To address this problem, addition of various growth factors, such as bone morphogenetic proteins (BMPs), parathyroid hormone (PTH) and platelet rich plasma (PRP), into structural allografts and synthetic substitutes have been considered. Although clinical applications of these factors have exhibited good bone formation, their further application was limited due to high cost and potential adverse side effects. Alternatively, bioinorganic ions such as magnesium, strontium and zinc are considered as alternative of osteogenic biological factors. Hence, this paper aims to review the currently available bone grafts and bone substitutes as well as the biological and bio-inorganic factors for the treatments of bone defect.

Abstract
Cephalomedullary nail (CMN) failure is a rare entity following hip fracture treatment. However, it poses significant challenges for revision surgery, both mechanically and biologically. Nail failure rates have been reported at < 2%; however, no published studies have reported revision surgery procedures and their respective outcomes. We present a regional experience, with outcomes, of the revision options. We identified 20 fatigued CMNs that underwent four different revision procedures. Mean age was 73 ± 15.24 years, with a 3:1 female preponderance, and a median ASA grade of 3. Post-operative CMN radiographs demonstrated a significant number of fractures were fixed in varus, with reductions in neck-shaft angles post-operatively. A "poor" quality of reduction resulted in significantly earlier nail failure, compared to "adequate" and "good" (p = 0.027). Tip-Apex Distance (TAD) mean was 23.2 ± 8.3 mm, and an adequate TAD with three-point fixation was seen in only 35% of cases. Mean time to failure was 401.0 ± 237.2 days, with mean age at failure of 74.0 ± 14.8 years. Options after failure included revision CMN nail, proximal femoral locking plate (PFLP), long-stem or restoration arthroplasty, or femoral endoprosthesis. Barthel Functional Index scores showed no significant difference at 3 and 12 months post-operatively, nor any difference between treatment groups. Mean 12-month mortality was 30%, akin to a primary hip fracture mortality risk according to NICE guidelines. Mortality rates were lowest in revision nails. Subsequent revision rates were higher in the PFLP group. There is no reported evidence on the best surgical technique for managing the failed CMN, with no clear functional benefit in the options above. Good surgical technique at the time of primary CMN surgery is critical in minimising fatigue failure. After revision, overall mortality rates were equivalent to reported primary hip fracture mortality rates. Further multicentre evaluations are required to assess which technique convey the best functional outcomes without compromising 12-month mortality rates.

Abstract
BACKGROUND Femoral material harvested using the Reamer-Irrigator-Aspirator (RIA) system is an alternative source for autogenous bone material in the treatment of non-unions, especially in combination with bone morphogenetic proteins (BMP). So far, there is no in vivo evidence of BMP-7 interacting with mesenchymal stem cells (MSCs) from RIA material (RIA-MSCs) and iliac crest autogenous bone (BMSCs). The aim of this study was to compare their osteogenic potential when stimulated with BMP-7 in vivo. METHODS RIA-MSC and BMSC from 11 donors were isolated and the character of MSCs was investigated in vitro. Constructs consisting of MSC, β-tricalcium phosphate and 2 concentrations of BMP-7 (0.1 µg/mL and 1 µg/mL) were implanted in mice for 8 weeks. Bone formation in the constructs was analyzed quantitatively and qualitatively. RESULTS All cell populations used were determined to be MSCs. The qualitative in vivo analysis showed formation of bone tissue. With regard to quantity, bone formation was significantly higher in RIA constructs without or with stimulation with 0.1 µg/mL BMP-7, compared with BMSC constructs. We found no significant differences between constructs stimulated with 1 µg/mL BMP-7. In the RIA group, we observed a significant increase in bone formation after stimulation with 0.1 µg/mL BMP-7. No significant change could be found using a higher concentration. In the BMSC group, we detected a significant increase when using 0.1 µg/mL and 1 µg/mL BMP-7. CONCLUSIONS RIA material is a source of MSCs with high osteogenic potential. Our results showed that stimulation by BMP-7 leads to an increased osteogenic potential of MSCs. In this respect, RIA-MSCs reacted more sensitively than BMSCs.

Abstract
Post-traumatic long bone osteomyelitis (PTOM) is a relatively frequent occurrence in patients with severe open fractures and requires treatment to prevent limb-threatening complications. The Masquelet technique represents a length-independent, two-staged reconstruction that involves the induction of a periosteal membrane and use of an antibiotic-impregnated cement spacer for the treatment of segmental bone loss that result from bone infection. In this review, we summarize recent developments regarding the diagnosis and treatment of long bone PTOM, with a special emphasis on the use of the Masquelet technique for reconstruction of wide diaphyseal defects.

Abstract
Bone is one of the most dynamic tissues in the human body that can heal following injury without leaving a scar. However, in instances of extensive bone loss, this intrinsic capacity of bone to heal may not be sufficient and external intervention becomes necessary. Several techniques are available to address this problem, including autogenous bone grafts and allografts. However, all these techniques have their own limitations. An alternative method is the technique of distraction osteogenesis, where gradual and controlled distraction of two bony segments after osteotomy leads to induction of new bone formation. Although distraction osteogenesis usually gives satisfactory results, its major limitation is the prolonged duration of time required before the external fixator is removed, which may lead to numerous complications. Numerous methods to accelerate bone formation in the context of distraction osteogenesis have been reported. A viable alternative to autogenous bone grafts for a source of osteogenic cells is mesenchymal stem cells from bone marrow. However, there are certain problems with bone marrow aspirate. Hence, scientists have investigated other sources for mesenchymal stem cells, specifically adipose tissue, which has been shown to be an excellent source of mesenchymal stem cells. In this paper, the potential use of adipose stem cells to stimulate bone formation is discussed.

Abstract
The quest to surpass the clinical efficacy of the allogeneic bone graft has had limited success, an outcome that is symbolic of tissue engineering as a whole. In this 'State of the Union'-type review, we highlight recent advances in the design of bone regenerative therapeutics using the primary elements of stem cells, growth factors and scaffolds, and identify major obstacles in their paths to the clinic. We underscore the need for rigorous performance criteria in the design of holistic tissue regenerative therapeutics, and an increased emphasis on the product production, storage and handling issues that will ultimately influence clinical success.

Abstract
The use of autograft bone is the best option when undertaking a procedure that requires bone graft because it is osteogenic, osteoconductive and osseo-inductive. Pain, morbidity and complications associated with harvesting iliac or non-iliac sites occur in between 6% and 30% of cases. An alternative source of graft with possibly a lower morbidity is the intramedullary canal. In this study, 28 patients undergoing 30 arthrodesis procedures on the hindfoot had a mean of 48 cm3 (43 to 50) of bone harvested locally from the hindfoot or the tibial shaft by antegrade or retrograde reaming. No patient sustained a fracture of the calcaneum, talus or tibia. There was no morbidity except for one complication when the reamer breached the medial tibial cortex. This healed uneventfully. This method of using the reamer–irrigator–aspirator system is an extension of the standard technique of intramedullary reaming of the lower limb: it produces good-quality bone graft with viable growth factors consistent with that of the iliac crest, and donor site morbidity is low. This is an efficient method of obtaining autologous bone for use in arthrodesis of the ankle or hindfoot.
