Abstract
BACKGROUND Treatment of complex proximal humeral fractures in the elderly is a challenge and reverse shoulder arthroplasty (RTSA) is now an important alternative to open reduction internal fixation (ORIF) with angular stable plate. The purpose of this study is to compare clinical and radiological outcomes of RTSA and ORIF in the elderly. METHODS We retrospectively analyzed patients treated for three- or four-part displaced fractures of the proximal humerus. Range of motion, disabilities of the arm, shoulder and hand (DASH) and Constant scores were recorded. X-ray exam in three projections completed the clinical observation at follow-up. RESULTS Forty-eight patients were enrolled after a mean follow-up of 37 months: 22 RTSA and 26 ORIF. Mean age at trauma was 74 years. Compared with RTSA patients, ORIF patients had significantly higher mean external rotation (28° vs. 14°) and better results in modal internal rotation (hand at D7 vs. hand at L5-S1). No significant differences were seen in DASH and Constant scores. Avascular necrosis and loss of reduction with varus dislocation of the humeral head were the most frequent causes of revision surgery in ORIF (34.6%) while the revision rate of the RTSA was 9.1%. CONCLUSION In this study, both treatments showed good clinical outcomes, but RTSA resulted in lower revision rate than ORIF. Even if external and internal rotation in RTSA patients were worse than ORIF, they did not affect the patient's quality of life. So, the reverse arthroplasty seems to be a more reliable treatment.

Abstract
Background: The aim of this study was to evaluate the morbidity and regeneration of descending genicular artery and bone on the donor site, the medial condyle of the femur, after harvesting the corticoperiosteal flap and to report the clinical, functional, and radiographic outcomes of the treatment of atrophic nonunions of upper limb with corticoperiosteal vascularized flap at 5-year follow-up. Methods: From January 2011 to January 2018, 36 patients (average age of 45.8 years) were enrolled and evaluated with clinical and radiographic follow-up (average time of 66 months). In 20 patients, magnetic resonance angiography was also performed preoperatively and postoperatively to investigate the fate of the descending genicular artery after harvesting the corticoperiosteal flap. Results: Radiographic evaluation demonstrated a success rate of 94.4% (average time of bone healing of 5.2 months). At the recipient site, clinical evaluation showed excellent results in 75% to 80% of cases, and at the donor site, no statistical differences were found between before and after surgery clinical condition. In all patients who underwent magnetic resonance imaging, images showed a complete recovery of the blood supply of the medial femoral condyle. Conclusions: Medial condyle corticoperiosteal flap represents a valid choice for the treatment of upper limb nonunions. This technique brings a very low morbidity on the donor site, with complete restoration of blood supply and bone tissue. The limit of this flap is its low mechanical support, which suggests performing this technique especially for the treatment of upper limb nonunions.

Abstract
BACKGROUND Bone voids can present challenging problems for the Orthopaedic surgeon, and are often treated with backfilling followed by structural stabilization. Recently, a magnesium based, and presumably resorbable, bone void filler (BVF) has been developed, but has limited longitudinal clinical data. Therefore, the purpose of this study was to investigate clinically relevant parameters and radiographic resorption characteristics of this novel magnesium based BVF (MgBVF) with long-term clinical data. METHODS All patients who underwent surgery by a single surgeon in which MgBVF was utilized from 2019 to 2020 were retrospectively reviewed. Clinical parameters including evidence of infection, wound breakdown, and wound drainage were reviewed. Radiographic resorption, evidence of joint extrusion of BVF, heterotopic ossification, and subsidence was assessed at each post-operative visit. Those with less than 6 month follow up were excluded from radiographic analysis of resorption. Postoperative images at two weeks were compared to each subsequent radiograph during follow up, and reviewed by each of the three authors in blinded fashion. Interval radiographs were assigned a grade of radiographic resorption which corresponded to estimated percent resorption: grade 1 (0-25%), grade 2 (25-50%), grade 3 (50-75%), or grade 4 (75-100%). After 2 weeks, this process was repeated, and both inter and intraobserver reliability scores were calculated. RESULTS Forty-two patients were identified for clinical review, and 18 for radiographic review. Average length of follow up was 209±113 days. Five patients experienced a postoperative complication: two wound infections, one delayed wound healing, one sterile serous drainage, and one catastrophic failure of the fixation construct. Four patients were noted to have postoperative joint subsidence of 2 mm or less. Average grade of resorption was found to be 1.5 ± 0.8, 1.7 ± 0.9, 2.9 ± 0.9, and 3.6 ± 0.6 at 6 weeks, 3 months, 6 months, and 1 year, respectively (p<0.001). Average kappa (intrarater reliability) was found to be 0.61, 0.41, 0.55, and 0.63 for each time interval, respectively. Interrater reliability increased form 0.19 at 6 weeks to 0.42 at 1 year. CONCLUSION This novel MgBVF demonstrates clinically relevant resorption, provides structural support in challenging bone voids, and does not appear to significantly increase risk of complications, setting it apart from previously described BVF's.

Abstract
The treatment of infected and non-infected non-unions remains a major challenge in trauma surgery. Due to the limited availability of autologous bone grafts and the need for local anti-infective treatment, bone substitutes have been the focus of tissue engineering for years. In this context, bioactive glasses are promising, especially regarding their anti-infective potential, which could reduce the need for local and systemic treatment with conventional antibiotics. The aim of this study was to investigate the osteoinductive and osteoconductive effects, as well as the anti-infectious potential, of S53P4 using a standardized non-union model, which had not been investigated previously. Using an already established sequential animal model in infected and non-infected rat femora, we were able to investigate bioactive glass S53P4 under realistic non-union conditions regarding its osteoinductive, osteoconductive and anti-infective potential with the use of µCT scans, biomechanical testing and histological, as well as microbiological, analysis. Although S53P4 did not lead to a stable union in the non-infected or the infected setting, µCT analysis revealed an osteoinductive effect of S53P4 under non-infected conditions, which was diminished under infected conditions. The osteoconductive effect of S53P4 remained almost negligible in histological analysis, even 8 weeks after treatment. Additionally, the expected anti-infective effect could not be demonstrated. Our data suggested that S53P4 should not be used in infected non-unions, especially in those with large bone defects.

Abstract
Purpose: The aim of this study was to quantify the rate of complications and reinterventions in patients treated with PHILOS plate for proximal humerus fractures (PHFs) synthesis. Methods: A comprehensive literature search was performed on the PubMed, Web of Science, Embase, and Cochrane databases up to 7 October 2021. Studies describing medium and long-term complications in PHF synthesis using the PHILOS plate were included. A systematic review and meta-analysis were performed on complications and causes of reinterventions. Assessment of risk of bias and quality of evidence was performed with the Downs and Black’s “Checklist for Measuring Quality”. Results: Seventy-six studies including 4200 patients met the inclusion criteria. The complication rate was 23.8%, and the main cause was screw cut-out (4.1%), followed by avascular necrosis (AVN) (3.1%) and subacromial impingement (1.5%). In patients over 55 years, the complication rate was 29.5%. In the deltopectoral (DP) approach the complication rate was 23.8%, and in the delto-split (DS) it was 17.5%, but no difference between the two approaches was seen when considering the type of fracture. The overall reintervention rate was 10.5% in the overall population and 19.0% in older patients. Conclusions: Proximal humerus synthesis with a PHILOS plate has high complications and reintervention rates. The most frequent complication was screw cut-out, followed by humeral head AVN and subacromial impingement. These results need to be further investigated to better understand both the type of patient and fracture that is more at risk of complications and reintervention and to compare pros and cons of the PHILOS plate with respect to the other solutions to manage PHFs.

Abstract
Background The Taylor Spatial Frame (TSF) has been widely used for tibial fracture. However, traditional radiographic measurement method is complicated and the reduction accuracy is affected by various factors. The purpose of this study was to propose a new marker- three dimensional (3D) measurement method and determine the differences of reduction outcomes, if any, between marker-3D measurement method and traditional radiographic measurement in the TSF treatment. Methods Forty-one patients with tibial fracture treated by TSF in our institution were retrospectively analyzed from January 2016 to June 2019, including 21 patients in the marker-3D measurement group (experimental group) and 20 patients in the traditional radiographic measurement group (control group). In the experimental group, 3D reconstruction with 6 markers installed on the TSF was performed to determine the electronic prescription. In the control group, the anteroposterior (AP) and lateral radiographs were performed for the traditional parameter measurements. The effectiveness was evaluated by the residual displacement deformity (RDD) and residual angle deformity (RAD) in the coronal and sagittal plane, according to the AP and lateral X-rays after reduction. Results All patients achieved functional reduction. The residual RDD in AP view was 0.5 (0, 1.72) mm in experimental group and 1.74 (0.43, 3.67) mm in control group. The residual RAD in AP view was 0 (0, 1.25) ° in experimental group and 1.25 (0.62, 1.95) °in control group. As for the lateral view, the RDD was 0 (0, 1.22) mm in experimental group and 2.02 (0, 3.74) mm in control group, the RAD was 0 (0, 0) ° in experimental group and 1.42 (0, 1.93) ° in control group. Significant differences in all above comparisons were observed between the two groups (AP view RDD: P = 0.024, RAD: P = 0.020; Lateral view RDD: P = 0.016, RAD: P = 0.004). Conclusions The present study introduced a marker-3D measurement method to complement the current TSF treatment. This method avoids the manual measurement error and improves the accuracy of fracture reduction, providing potential advantages of bone healing and function rehabilitation.

Abstract
BACKGROUND Restoration of the bone defects caused by infection or disease remains a challenge in orthopedic surgery. In recent studies, scaffold-free engineered tissue with a self-secreted extracellular matrix has been proposed as an alternative strategy for tissue regeneration and reconstruction. Our study aimed to engineer and fabricate self-assembled osteogenic and scaffold-free tissue for bone regeneration. METHODS Osteogenic scaffold-free tissue was engineered and fabricated using fetal cartilage-derived progenitor cells, which are capable of osteogenic differentiation. They were cultured in osteogenic induction environments or using demineralized bone powder for differentiation. The fabricated tissue was subjected to real-time qPCR, biochemical, and histological analyses to estimate the degree of in vitro osteogenic differentiation. To demonstrate bone formation in an in vivo environment, scaffold-free tissue was transplanted into the dorsal subcutaneous site of nude mice. Bone development was monitored postoperatively over 8 weeks by the observation of calcium deposition in the matrix. RESULTS In the in vitro experiments, engineered osteogenically induced scaffold-free tissue demonstrated three-dimensional morphological characteristics, and sufficient osteogenic differentiation was confirmed through the quantification of specific osteogenic gene markers expressed and calcium accumulation within the matrix. Following the evaluation of differentiation efficacy, in vivo experiments revealed distinct bone formation, and that blood vessels had penetrated the fabricated tissue. CONCLUSION The novel engineering of scaffold-free tissue with osteogenic potential can be used as an optimal bone graft substitute for bone regeneration.

Abstract
Recently, reamer-irrigator-aspirator (RIA) systems have been increasingly used to harvest autologous bone grafts. RIA graft materials contain bone marrow, which provides a viable source to derive large numbers of mesenchymal stem cells. Low-intensity pulsed ultrasound (LIPUS) significantly accelerates the differentiation of stem cells derived from bone marrow. This in vitro study investigated the effect of LIPUS on the osteogenic activity and differentiation of RIA graft-derived cells. A small amount of RIA graft was obtained from seven patients. After the cells derived from RIA grafts were cultured, they were divided into two groups: the LIPUS and control groups. LIPUS was applied once daily for 20 min (1.5 MHz, pulse duration: 200 µs, pulse repetition rate: 1 kHz, spatial average-temporal average intensity: 30 mW/cm2). Alkaline phosphatase activity (113.4% and 130.1% on days 7 and 14), expression of osteoblast-related genes (ALP, Runx2) and mineralization (135.2% on day 21) of the RIA graft-derived cells were significantly higher in the LIPUS group than in the control group. However, LIPUS did not affect the cell proliferation of RIA graft-derived cells. This study indicates that LIPUS may enhance the healing of non-union and critical bone defects treated by autologous bone grafting using the RIA system.

Abstract
AIMS The purpose of this study is to systematically review the randomized controlled trials on the various treatment options that can be utilized in the management of displaced proximal humerus fractures. MATERIALS & METHODS Based on the PRISMA guidelines, three independent reviewers performed a systematic review of the literature. Randomized control trials (RCTs) focusing on the outcomes of the following interventions in the management of PHFs were considered for inclusion; (1) non-operative or conservative (NOC) management, (2) open reduction and internal fixation (ORIF), (3) intra-medullary nailing (IMN), (4) shoulder hemi-arthroplasty (HA), and (5) reverse shoulder arthroplasty (RSA). Network meta-analyses were performed using R and studies were ranked according to their P-score. RESULTS Our study included 13 RCTs. RSA had improvements in abduction, constant score, flexion, as well as lowest rates of malunion and osteonecrosis when compared to other management modalities (P-Score = 0.9786, P-Score = 0.9998, P-Score = 0.9909, P-Score = 0.9590 and P-Score = 0.8042 respectively). HA was found to have improvements in health-related quality of life scores when compared to other management modalities (P-Score = 0.9672). ORIF had the highest improvement in quick disability of arm, shoulder and hand scores and visual analogue scale scores (P-Score = 0.8209 and P-Score = 0.7155 respectively). NOC was found to have the lowest rate of conversion to surgical intervention, with RSA having the lowest rate of surgical interventions (P-Score = 0.9186 and P-Score = 0.7497 respectively). DISCUSSION & CONCLUSION RSA offers satisfactory improvements in clinical and functional outcomes when compared to other non-operative and operative treatment options in the management of carefully selected proximal humerus fractures, with a minimal revision rate when compared to other surgical management modalities.

Abstract
OBJECTIVE Collection of bone graft with the Reamer-Irrigator-Aspirator (RIA) system has become common practice across the field of orthopaedic surgery. While RIA bone graft is typically obtained from native long bones, grafting material can likewise be harvested from long bones that have previously undergone the placement and removal of an intramedullary nail, a process termed re-reamed RIA (RRR). The purpose of this study was to evaluate the total protein and growth factor concentrations present in native-RIA (NR) compared with RRR samples. METHODS NR and RRR bone grafts were collected intraoperatively with the RIA system and processed to evaluate both the aqueous and the hard tissue components. Total protein concentration and specific growth factors were analyzed using standard bicinchoninic acid and multiplex assays, respectively. Analyte levels were then normalized to the total amount of protein detected. RESULTS Total protein levels were comparable between NR and RRR samples for both the aqueous filtrate and the hard tissue samples. When normalized, while levels of bone morphogenic protein-2 and vascular endothelial growth factor were comparable in the hard tissue component, the aqueous filtrate from the RRR sample was found to have elevated levels of growth factors, with bone morphogenic protein-2 reaching statistical significance. CONCLUSIONS This study demonstrates that ample protein is found within both NR and RRR samples, with comparable or elevated levels of osteogenic growth factors found within RRR samples. Future, larger, prospective studies will be required to evaluate the osteogenic potential and clinical efficacy of NR and RRR cancellous bone grafts to validate their equivalency.

Abstract
BACKGROUND Reamer-Irrigator-Aspirator (RIA) of long bones is increasingly being used as an alternative to iliac crest harvesting for bone-grafts. This meta-analysis compares both harvesting techniques with regard to donor site morbidity, healing potency and implantation site morbidity. METHODS PubMed/Medline/Embase/CENTRAL/CINAHL were searched for both randomized clinical trials (RCT) and observational studies. Effect estimates were pooled across studies using random effects models and presented as weighted odds ratio (OR) with corresponding 95% confidence interval (95%CI). RESULTS A total of 5 studies were included. RIA carries a lower risk for chronic pain (0% versus 14.2%, OR 0.08, 95% CI 0.02 - 0.35) and infection (1% versus 5.9%, OR 0.29, 95% CI 0.09- 0.9) at the donor site compared to iliac crest harvesting. Iliac crest bone-harvesting has an inherent additional risk of neuropraxia of the lateral femoral cutaneous nerve and numbness of the scar which is not encountered in RIA harvesting. Risk for other reported complications such as hematoma and iatrogenic fractures appear equal in both groups. The clinical healing potential of both bone grafts, in terms of union rate (OR 1.53, 95%CI 0.62 - 3.75) at the implantation site and time-to-union (MD 0.44 months, 95%CI -1.72 - 0.83), seems equal. CONCLUSION The main difference between RIA and iliac crest bone graft harvesting is the considerable higher risk of chronic pain of the pelvic procedure. Although risk for infection was also higher for the iliac crest group, the absolute difference is relatively small. Evidence suggests an equal healing potential of the grafts themselves irrespective of harvesting method.

Abstract
The number of patients with osteoarthritis of the ankle, which are treated by arthroplasty, has continuously increased in recent years. The survival time of these implants is far below the results following hip and knee arthroplasty. In some cases a failure rate of approximately 1% per year or a survival rate of 70% after 10 years has been reported. The most frequent reasons for revision of an ankle prosthesis are aseptic loosening, technical implantation errors and persisting pain. For the revision of an ankle prosthesis there are basically two treatment options. For a long time, ankle arthrodesis was considered the gold standard after a failed prosthesis. In recent years, there has been an increasing trend towards re-implantation of an ankle prosthesis, as this preserves the functionality and mobility of the ankle joint as far as possible. Depending on the reason for failure and the size of the bony defect, a decision must be made regarding a one-stage and a two-stage procedure with bone augmentation. This article presents the advantages and disadvantages of arthrodesis and revision arthroplasty after failed primary ankle arthroplasty and highlights the special features of surgery.

Abstract
Humeral shaft fractures account for 1% to 3% of all fractures. Traditional nonsurgical treatment with a functional brace is still the standard treatment of these fractures; however, modern studies have reported that nonunion rates may be as high as 33%. Recent information suggests that the development of nonunion after nonsurgical treatment may be identified as early as 6 to 8 weeks postinjury. Even with surgical treatment, nonunion rates as high as 10% have been reported. Regardless of the original treatment method, nonunion results in poor quality of life for the patient and therefore should be addressed. A thorough preoperative evaluation is important to identify any metabolic or infectious factors that may contribute to the nonunion. In most cases, surgical intervention should consist of compression plating with or without bone graft. Although most patients will achieve union with standard surgical intervention, some patients may require specialized techniques such as cortical struts or vascularized fibular grafts. Successful treatment of humeral shaft nonunion improves function, reduces disability, and improves the quality of life for patients. In this article, we outline our approach to the treatment of humeral shaft nonunion in a variety of clinical settings.

Abstract
Purpose Currently, sacroiliac joint dislocations, including crescent fracture–dislocations, are treated using several techniques that have certain issues. We present the technical details and clinical outcomes of a new technique, anterior sacroiliac stabilisation (ASIS), performed using spinal instrumentation. Methods ASIS is performed with the patient in a supine position via the ilioinguinal approach. The displacements are reduced and fixed by inserting cancellous screws from the sacral ala and iliac brim; the screw heads are bridged using a rod and locked. We performed a retrospective review of patients with iliosacral disruption who underwent ASIS between May 2012 and December 2020 at two medical facilities. The patients were assessed for age, sex, injury type, associated injuries, complications, functional outcome by evaluating the Majeed pelvic score after excluding the sexual intercourse score and fracture union. Results We enrolled 11 patients (median age: 63 years). The median operative time was 195 min, median blood loss was 570 g, and eight patients (72.3%) required blood transfusion. The sacral and iliac screws had a diameter of 6.0–8.0 mm and 6.2–8.0 mm, and a length of 50–70 mm and 40–80 mm, respectively. Bone union was achieved with no marked loss of reduction in the median follow-up period of 12 months in all cases. The median Majeed score at the final follow-up was 85/96. Conclusion ASIS is a rigid internal fixation method that provides angular stability. Despite invasiveness issues compared to iliosacral screw fixation, this method is easy to confirm and achieves precise reduction.

Abstract
Diffusion-controlled crystallization in a hydrogel has been investigated to synthesize organic/inorganic hybrid composites and obtain a fundamental understanding of the detailed mechanism of biomineralization. Although calcium phosphate/hydrogel composites have been intensively studied and developed for the application of bone substitutes, the synthesis of homogeneous and integrated composites remains challenging. In this work, diffusion-controlled systems were optimized by manipulating the calcium ion flux at the interface, concentration gradient, and diffusion coefficient to synthesize homogeneous octacalcium phosphate/hydrogel composites with respect to the crystal morphology and density. The ion flux and local pH play an important role in determining the morphology, density, and phase of the crystals. This study suggests a model system that can reveal the relation between local conditions and the resulting crystal phase in diffusion-limited systems and provides a synthetic method for homogeneously organized organic/inorganic composites.

Abstract
BACKGROUND Most greater tuberosity fractures can be treated without surgery but some have a poor prognosis. The surgical procedures for avulsion fractures of the humeral greater tuberosity include screw fixation, suture anchor fixation, and plate fixation, all of which have treatment-associated complications. To decrease surgical complications, we used a modified suture bridge procedure under direct vision and a minimally invasive small incision to fix fractures of the greater tuberosity of the humerus.
AIM To investigate the clinical efficacy and outcomes of minimally invasive modified suture bridge open reduction of greater tuberosity evulsion fractures.
METHODS Sixteen patients diagnosed between January 2016 and January 2019 with an avulsion-type greater tuberosity fracture of the proximal humerus and treated by minimally invasive open reduction and modified suture bridges with anchors were studied retrospectively. All were followed up by clinical examination and radiographs at 3 and 6 wk, 3, 6 and 12 mo after surgery, and thereafter every 6 mo. Outcomes were assessed preoperatively and postoperatively by a visual analog scale (VAS), the University of California Los Angeles (UCLA) shoulder score, the American Shoulder and Elbow Surgeon score (ASES), and range of motion (ROM) for shoulders.
RESULTS Seven men and nine women, with an average age of 44.94 years, were evaluated. The time between injury and surgery was 1-2 d, with an average of 1.75 d. The mean operation time was 103.1 ± 7.23 min. All patients achieved bone union within 3 mo after surgery. VAS scores were significantly decreased (P = 0.002), and the mean degrees of forward elevation (P = 0.047), mean degrees of abduction (P = 0.035), ASES score (P = 0.092) were increased at 3 wk. The UCLA score was increased at 6 wk (P = 0.029) after surgery. The average degrees of external rotation and internal rotation both improved at 3 mo after surgery (P = 0.012 and P = 0.007, respectively). No procedure-related deaths or incision-related superficial or deep tissue infections occurred.
CONCLUSION Modified suture bridge was effective for the treatment of greater tuberosity evulsion fractures, was easier to perform, and had fewer implants than other procedures.

Abstract
Visual cognitive ability has previously been associated with anterior cruciate ligament injury and injury risk biomechanics in healthy athletes. Neuroimaging reports have identified increased neural activity in regions corresponding to visual-spatial processing, sensory integration, and visual cognition in individuals after anterior cruciate ligament reconstruction (ACLR), indicating potential neural compensatory strategies for motor control. However, it remains unclear whether there is a relationship between visual cognition, neural activity, and metrics of neuromuscular ability after ACLR. The purpose of this study was to (1) evaluate the relationship between visual cognitive function and measurements of neuromuscular control (proprioception and time to stability [TTS]), isokinetic strength, and subjective function, and (2) examine the neural correlates of visual cognition between ACLR (n = 16; time since surgery 41.4 ± 33.0 months) and demographically similar controls (n = 15). Visual cognition was assessed by the ImPACT visual motor and visual memory subscales. Outcome variables of proprioception to target knee angle 20°, landing TTS, strength, and subjective function were compared between groups, and visual cognition was correlated within groups to determine the relationship between visual cognition and outcome variables controlled for time from surgery (ACLR group). The control group had better IKDC scores and strength. Visual memory and visual motor ability were negatively associated with proprioception error (r = -0.63) and TTS (r = -0.61), respectively, in the ACLR group but not controls. Visual cognition was associated with increased neural activity in the precuneus and posterior cingulate cortex in the ACLR group but not control participants. These data suggest the neural strategy in which ACLR participants maintain proprioception and stability varies, and may depend on visual cognition and sensory integration neural activity.

Abstract
AIMS To develop a model to evaluate the cost-effectiveness of 4 mg dibotermin alfa/absorbable collagen sponge (ACS) versus iliac crest bone graft (ICBG) in patients with lumbar degenerative disc disease in the United Kingdom. MATERIALS & METHODS A Markov decision-analytic model was constructed to calculate costs and quality-adjusted life-years over a 4-year time horizon in each treatment group, from a United Kingdom National Health Service perspective. An individual patient data meta-analysis was undertaken to synthesize data from four randomized controlled trials and two single-arm studies concerning health-related quality of life and procedural resource use. Current cost data from the United Kingdom were then applied to determine the overall mean cost per patient in each group. One-way and probabilistic sensitivity analyses were undertaken to explore the impact of parameter uncertainty. RESULTS The model predicted 4-year discounted cost savings of £192 per patient treated with dibotermin alfa/ACS, compared with ICBG, and a gain of 0.0114 QALYs per patient over the same time period. Sensitivity analyses indicated that the results were most sensitive to variability in the differences in health-related quality of life and secondary surgery rate, with dibotermin alfa/ACS having a 60% probability of being cost-effective at a willingness-to-pay threshold of £20,000 per QALY gained. LIMITATIONS There is uncertainty in the difference in cost and QALYs between the two groups. However, comprehensive sensitivity analyses were undertaken to explore this and present the results in a transparent manner. CONCLUSIONS Our results provide an economic case for the use of 4 mg dibotermin alfa/ACS versus iliac crest bone graft, with additional health benefits predicted at reduced overall cost.

Abstract
INTRODUCTION Surgical treatment of complex humeral head fractures in the elderly is challenging due to osteoporotic bone, comorbidities and reduced compliance. The treatment strategy (reconstruction versus replacement) should allow for a functional aftercare and result in a high patient satisfaction. Major complications leading to surgical revision are crucial and should be avoided. The purpose of this study was to analyse the major complication rate leading to surgical revision and the patient-based outcome in complex humeral head fractures of the elderly population treated either using locking plate fixation (LCP) or reversed total shoulder arthroplasty (rTSA). MATERIALS AND METHODS All patients older than 65 years surgically treated due to a four-part fracture of the proximal humerus between 2003 and 2015 were enrolled in our retrospective study. Major complications and revision rates were recorded and functional outcome was assessed using the Munich Shoulder Questionnaire (MSQ) allowing for qualitative self-assessment of the Shoulder Pain and Disability Index (SPADI), of the Disability of the Arm, Shoulder and Hand (DASH) score and of the Constant Score. RESULTS A cohort of 103 patients with a mean age of 73.4 ± 6.2 years suffering from four-part fractures of the humeral head were enrolled. 63 patients were treated using the LCP fixation compared to 40 rTSAs. There were no significant differences in the patient-reported functional outcome. The revision rate was significantly higher in the LCP group (10/63; 15.9%) compared to the rTSA group (1/40; 2.5%). Reasons for revision were avascular head necrosis, cut-out of screws, secondary dislocation of the greater tuberosity and hypersensitivity to metal. CONCLUSIONS Reversed total shoulder arthroplasty and locking plate fixation are both established surgical procedures for the management of complex proximal humerus fractures in the elderly leading to similar functional results. However the revision rate in the rTSA group was significantly lower. Primary rTSA should, therefore, be favoured in multimorbid elderly patients with an increased complication risk to avoid repeated anaesthesia.

Abstract
Femoral shaft nonunions are disabling complications of fractures, with relevant socioeconomic and psychological impact. The incidence of femoral shaft nonunions is not negligible, ranging between 1% and 10% after intramedullary nailing, but can exceed 20% in case of subtrochanteric fractures. Treatment options are influenced by pathomechanical, anatomical, and clinical factors. Hypertrophic nonunions are usually treated by enhancing stability of fixation, while atrophic nonunions require additional biological stimulation to achieve bone union. The Reamer-Irrigator-Aspirator (RIA) System® was developed to reduce intramedullary pressure and heat generation during intramedullary reaming, thus preventing thermal necrosis and decreasing the risk of fat embolism. The RIA System allows to provide large volumes of high-quality morselized autologous bone, that has shown high osteogenetic and osteoinductive properties. Therefore, its use has been expanded as a valuable source of autologous bone graft for the treatment of large bone defects of different nature. In this article, we present two cases of complex femoral nonunions treated with the use of the RIA System. A review of the published literature on the treatment of femoral nonunions with RIA was also performed. Core tip: In case of atrophic nonunions, the RIA System can be used to obtain biologically active tissue to enhance bone healing. Despite the absence of high-quality studies focused on femoral nonunions, the efficacy of RIA is well-known and orthopaedic surgeons should be aware of this powerful tool.

Abstract
STUDY DESIGN Prospective, randomized, controlled preclinical study. OBJECTIVE The objective of this study was to compare the host inflammatory response of our previously described hyperelastic, 3D-printed (3DP) hydroxyapatite (HA)-demineralized bone matrix (DBM) composite scaffold to the response elicited with the use of recombinant human bone morphogenetic protein-2 (rhBMP-2) in a preclinical rat posterolateral lumbar fusion model. SUMMARY OF BACKGROUND DATA Our group previously found that this 3D-printed HA-DBM composite material shows promise as a bone graft substitute in a preclinical rodent model, but its safety profile had yet to be assessed. METHODS Sixty female Sprague-Dawley rats underwent bilateral posterolateral intertransverse lumbar spinal fusion using with the following implants: 1) type I absorbable collagen sponge (ACS) alone; 2) 10 μg rhBMP-2/ACS; or 3) the 3DP HA-DBM composite scaffold (n = 20). The host inflammatory response was assessed using magnetic resonance imaging, while the local and circulating cytokine expression levels were evaluated by enzyme-linked immunosorbent assays at subsequent postoperative time points (N = 5/time point). RESULTS At both 2 and 5 days postoperatively, treatment with the HA-DBM scaffold produced significantly less soft tissue edema at the fusion bed site relative to rhBMP-2-treated animals as quantified on magnetic resonance imaging. At every postoperative time point evaluated, the level of soft tissue edema in HA-DBM-treated animals was comparable to that of the ACS control group. At 2 days postoperatively, serum concentrations of tumor necrosis factor-α and macrophage chemoattractant protein-1 were significantly elevated in the rhBMP-2 treatment group relative to ACS controls, whereas these cytokines were not elevated in the HA-DBM-treated animals. CONCLUSION The 3D-printed HA-DBM composite induces a significantly reduced host inflammatory response in a preclinical spinal fusion model relative to rhBMP-2.Level of Evidence: N/A.

Abstract
INTRODUCTION Proximal humerus fractures are common injuries of the elderly. Different treatment options, depending on fracture complexity and stability, have been recommended in the literature. Particularly for varus displaced fractures with a lack of medial support, and patients suffering from osteoporosis, structural allografts can be used to enhance the stability of the construct. An individually shaped allograft has been suggested in the literature and investigated in a clinical setting. However, biomechanical properties have yet to be evaluated. MATERIALS AND METHODS Twenty-four fresh-frozen humeri and 12 femoral heads were obtained, and an unstable three-part fracture of the humeral head was simulated. Fracture fixation was achieved by using a locking plate in both groups. In the test group, a mushroom-shaped allograft was tailored out of a femoral head to individually fit the void inside the humeral head. Specimens were fitted with a 3D motion analysis system and cyclically loaded with a stepwise increasing load magnitude in a varus-valgus bending test until failure or up to a maximum of 10,000 load cycles. RESULTS The mushroom group reached a significantly higher number of load cycles (8342; SD 1,902; CI 7133-9550) compared to the control group (3475; SD 1488; CI 2530-4420; p < 0.001). Additionally, the test group showed significantly higher stiffness values concerning all observational points (p < 0.001). CONCLUSION This mushroom-shaped allograft in combination with a locking plate significantly increased load to failure as well as stiffness of the construct when exposed to varus-valgus bending forces. Therefore, it might be a viable option for surgical treatment of unstable and varus displaced proximal humerus fractures to superiorly prevent loss of reduction and varus collapse.

Abstract
Three-part proximal humerus fractures in the elderly continue to be difficult to surgically treat. We evaluated the Hawkins wiring (HW) technique, which utilizes figure-of-eight tension band wiring, to treat three-part proximal humerus fractures involving the greater tuberosity. Currently, there is a paucity of data detailing patient outcomes and radiographic follow-up of this technique. The purpose of this case series is to evaluate patient reported outcomes and radiographic follow-up for fractures treated with this technique. Over two years, six patients at our institution underwent HW to treat three-part proximal humerus fractures. Average DASH and Oxford Shoulder scores (OSS) were 20.4 (range, 1–40) and 40 (range, 33–46) respectively. All patients had satisfactory return of function after surgery. Radiographic union was achieved in all six patients and there were no reported complications. HW technique is an efficacious treatment for three-part proximal humerus fractures in elderly patients.

Abstract
OBJECTIVE Posterior C1-2 fixation without fusion makes it possible to restore atlantoaxial motion after removing the implant, and it has been used as an alternative technique for odontoid fractures; however, the long-term efficacy of this technique remains uncertain. The purpose of the present study was to explore the long-term follow-up outcomes of patients with odontoid fractures who underwent posterior C1-2 fixation without fusion. METHODS A retrospective study was performed on 62 patients with type II/III fresh odontoid fractures who underwent posterior C1-2 fixation without fusion and were followed up for more than 5 years. The patients were divided into group A (23 patients with implant removal) and group B (39 patients without implant removal) based on whether they underwent a second surgery to remove the implant. The clinical outcomes were recorded and compared between the two groups. In group A, the range of motion (ROM) of C1-2 was calculated, and correlation analysis was performed to explore the factors that influence the ROM of C1-2. RESULTS A solid fracture fusion was found in all patients. At the final follow-up, no significant difference was found in visual analog scale score or American Spinal Injury Association Impairment Scale score between the two groups (p > 0.05), but patients in group A had a lower Neck Disability Index score and milder neck stiffness than did patients in group B (p < 0.05). In group A, 87.0% (20/23) of the patients had atlantoodontoid joint osteoarthritis at the final follow-up. In group A, the C1-2 ROM in rotation was 6.1° ± 4.5° at the final follow-up, whereas the C1-2 ROM in flexion-extension was 1.8° ± 1.2°. A negative correlation was found between the C1-2 ROM in rotation and the severity of tissue injury in the atlantoaxial region (r = -0.403, p = 0.024) and the degeneration of the atlantoodontoid joint (r = -0.586, p = 0.001). CONCLUSIONS Posterior C1-2 fixation without fusion can be used effectively for the management of fresh odontoid fractures. The removal of the implant can further improve the clinical efficacy, but satisfactory atlantoaxial motion cannot be maintained for a long time after implant removal. A surgeon should reconsider the contribution of posterior C1-2 fixation without fusion and secondary implant removal in preserving atlantoaxial mobility for patients with fresh odontoid fractures.

Abstract
OBJECTIVE Therapy of pubic related groin pain via minimally invasive symphysioplasty. INDICATIONS Therapy of refractory pubic related groin pain based on osteitis pubis. CONTRAINDICATIONS Groin pain from causes other than pubic related groin pain. SURGICAL TECHNIQUE After a minimally invasive approach, an incision in the anterior capsule is made while protecting the dorsal capsule parts and the arcuate pubic ligament. The symphysis end plates are remodeled arthroscopically assisted using a surgical burr. The newly created pubic symphysis joint is filled with autogenous fibrin to support the formation of a new discus interpubicus. POSTOPERATIVE MANAGEMENT Partial weight-bearing for 4 weeks with 20 kg using crutches is recommended. During the first 4 weeks the range of motion should be restricted. RESULTS Since 2010, 10 athletes (7 men, 3 women; average age 34.1 ± 7.8 (23-47) years) have undergone arthroscopically assisted minimally invasive symphysioplasty and treatment of femoroacetabular impingement syndrome. The average follow-up time was 5.1 (2-9) years. All patients returned to their sport level. The mean preoperative Nonarthritic Hip Score (NAHS) of 64.4 ± 15.1 (32.1-86.5) points improved to a mean postoperative NAHS of 91.4 ± 9.8 (62.4-98.75) points (p < 0.0001). The average patient satisfaction (scale 0 to 10; 10 highest satisfaction) was 9.8 ± 0.4 (9-10).

Abstract
With the limitation of autografts, the development of alternative treatments for bone diseases to alleviate autograft-related complications is highly demanded. In this study, a tissue-engineered bone was formed by culturing rat bone marrow cells (RBMCs) onto porous apatite-fiber scaffolds (AFSs) with three-dimensional (3D) interconnected pores using a radial-flow bioreactor (RFB). Using the optimized flow rate, the effect of different culturing periods on the development of tissue-engineered bone was investigated. The 3D cell culture using RFB was performed for 0, 1 or 2 weeks in a standard medium followed by 0, 1 or 2 weeks in a differentiation medium. Osteoblast differentiation in the tissue-engineered bone was examined by alkaline phosphatase (ALP) and osteocalcin (OC) assays. Furthermore, the tissue-engineered bone was histologically examined by hematoxylin and eosin and alizarin red S stains. We found that the ALP activity and OC content of calcified cells tended to increase with the culture period, and the differentiation of tissue-engineered bone could be controlled by varying the culture period. In addition, the employment of RFB and AFSs provided a favorable 3D environment for cell growth and differentiation. Overall, these results provide valuable insights into the design of tissue-engineered bone for clinical applications.

BACKGROUND The purpose of this study was to evaluate the biomechanical properties of two different fixation constructs in varus collapse proximal humerus fracture, locking plate with medial support screw and locking plate with intramedullary fibular graft. METHODS We used 8 pairs of undamaged fresh-frozen humen cadaveric humeri and fibula from patients ranging in age from 62 to 81 years. We simulated a proximal humerus fracture with medial comminution using wedge shaped osteotomy. One group was fixed with locking plate with medial support screws, the other group with locking plate with intramedullary fibular graft. Biomechanical test was carried out using servohydraulic material testing system. We measured displacement of specimens under cyclic load test, maximum failure load, initial stiffness, and mode of failure under increasing load test. FINDINGS Under cyclic loading, the displacement of the specimen was significantly less in the locking plate with fibular strut graft group than in the locking plate with medial support screws group. (p = 0.012) Under increasing load test, the Locking plate with fibular strut graft group showed higher values in both maximum failure load and initial stiffness than the Locking plate with medial support screws group, and this was statistically significant. (p = 0.012, p = 0.001). INTERPRETATION In biomechanical study, the locking plate with fibular strut graft showed significantly better results in all of the maximum failure load, initial stiffness, and gap depletion compared to the locking plate with medial support screws. LEVEL OF EVIDENCE Level IV.

Abstract
Athletes are at risk for a variety of injuries not typically sustained in everyday life. The team physician must be capable of not only identifying and treating injuries as they occur, but he or she must be armed with the knowledge to minimize the risk of injuries before they occur. This review serves to provide an overview of the various sport-specific injuries typically encountered by team physicians. Injuries are grouped by body part and/or organ system, when possible. We do not aim to cover in detail the various treatments for these injuries; rather, we hope that this article provides a comprehensive overview of sport-specific injury, and demonstrate the well-roundedness in skills that must be possessed by team physicians.

Abstract
BACKGROUND Proximal humeral fractures are common injuries. Although certain fracture types may benefit from surgery including open reduction-internal fixation (ORIF), the optimal method for fixation is unclear. Newer implant designs that improve healing by minimizing hardware failure and recurrent fracture displacement may optimize clinical outcomes. METHODS Over a 27-month period, 37 consecutive patients with proximal humeral fractures were treated by a single surgeon with a lateral humeral plate through which an intramedullary nitinol cage was inserted. Additional screws were placed through the tuberosities and cage as required. Fractures were classified by both the Neer classification and angulation or displacement in the coronal plane. At most recent follow-up, radiographic results, patient-reported outcome measurements, range of motion, complications, and reoperations were recorded. RESULTS Thirty-one patients had a minimum of 1 year of clinical and radiographic follow-up. The average follow-up period was 91 weeks. By use of the Neer classification, there were 4 two-part, 21 three-part, and 6 four-part fractures. Twenty-one fractures were displaced in valgus and 10 in varus. Outcome measurements at most recent follow-up demonstrated an average American Shoulder and Elbow Surgeons score of 68; Single Assessment Numeric Evaluation score of 70; Quick Disabilities of the Arm, Shoulder and Hand score of 27; Veterans RAND-12 Physical Component Score of 37 and Mental Component Score of 51; Constant score of 55; Patient-Reported Outcomes Measurement Information System score of 29; and Oxford Shoulder Score of 23. Average active range of motion showed forward elevation of 134°, abduction of 91°, external rotation with the arm at the side of 30° (range, -10° to 60°), and internal rotation with the arm at the side to L1 (range, T6-S4). There were 11 complications (35%), including 2 cases of axillary nerve neurapraxia that resolved and 4 cases of avascular necrosis (13%). Unplanned reoperations were performed in 6 patients (19%). One patient underwent revision for loose hardware removal, 1 patient underwent revision ORIF after a fall, and 4 patients required component removal and revision to shoulder arthroplasty. No screw cutout or varus head collapse occurred. CONCLUSION The management of proximal humeral fractures remains challenging. Our results demonstrate similar fracture healing, clinical improvement, and complication rates compared with conventional ORIF with screws and a side plate. At 1 year of follow-up, there were low rates of recurrent fracture displacement and screw cutout. There was a higher-than-expected rate of avascular necrosis as compared with other studies using a similar fixation construct. Larger studies and longer follow-up may demonstrate decreased rates of revision surgery and superior outcomes. Additional studies may determine whether this fixation method is superior to others for proximal humeral fractures.

Abstract
Although autogenous bone grafts are an optimal filling material for the induced membrane technique, limited availability and complications at the harvest site have created a need for alternative graft materials. We aimed to investigate the effect of an rhBMP-2-coated, 3D-printed, macro/microporous CaO-SiO2 -P2 O5 -B2 O3 bioactive ceramic scaffold in the treatment of critical femoral bone defects in rabbits using the induced membrane technique. A 15-mm segmental bone defect was made in the metadiaphyseal area of the distal femur of 14 rabbits. The defect was filled with polymethylmethacrylate cement and stabilized with a 2.0 mm locking plate. After the membrane matured for 4 weeks, the scaffold was implanted in two randomized groups: Group A (3D-printed bioceramic scaffold) and Group B (3D-printed, bioceramic scaffold with rhBMP-2). Eight weeks after implantation, the radiographic assessment showed that the healing rate of the defect was significantly higher in Group B (7/7, 100%) than in Group A (2/7, 29%). The mean volume of new bone formation around and inside the scaffold doubled in Group B compared to that in Group A. The mean static and dynamic stiffness were significantly higher in Group B. Histological examination revealed newly formed bone in both groups. Extensive cortical bone formation along the scaffold was found in Group B. Successful bone reconstruction in critical-sized bone defects could be obtained using rhBMP-2-coated, 3D-printed, macro/microporous bioactive ceramic scaffolds. This grafting material demonstrated potential as an alternative graft material in the induced membrane technique for reconstructing critical-sized bone defects.

Abstract
BACKGROUND The reamer irrigator aspirator (RIA) is a relatively recent device that is placed in the medullary canal of long bones to harvest a large volume of bone marrow, which is collected in a filtered canister. This study compares outcomes and complications of the RIA versus a traditional iliac crest bone graft (ICBG) for the treatment of bone defects. METHODS This meta-analysis was conducted according to the PRISMA guidelines. The Embase, Google Scholar, PubMed, and Scopus databases were accessed in June 2021. All clinical trials comparing the RIA and ICBG with a minimum of 6 months follow-up were included. RESULTS Data from 4819 patients were collected. The RIA group demonstrated lower site pain (P < 0.0001), fewer infections (P = 0.001), and a lower rate of adverse events (P < 0.0001). The ICBG group demonstrated a greater rate of bone union (P < 0.0001). There was no difference between groups in VAS (P = 0.09) and mean time to union (P = 0.06). CONCLUSION The current evidence supports the use of the RIA, given its low morbidity and short learning curve.

Abstract
Models of bone remodelling could be useful in drug discovery, particularly if the model is one that replicates bone regeneration with reduction in osteoclast activity. Here we use nanovibrational stimulation to achieve this in a 3D co-culture of primary human osteoprogenitor and osteoclast progenitor cells. We show that 1000 Hz frequency, 40 nm amplitude vibration reduces osteoclast formation and activity in human mononuclear CD14+ blood cells. Additionally, this nanoscale vibration both enhances osteogenesis and reduces osteoclastogenesis in a co-culture of primary human bone marrow stromal cells and bone marrow hematopoietic cells. Further, we use metabolomics to identify Akt (protein kinase C) as a potential mediator. Akt is known to be involved in bone differentiation via transforming growth factor beta 1 (TGFβ1) and bone morphogenetic protein 2 (BMP2) and it has been implicated in reduced osteoclast activity via Guanine nucleotide-binding protein subunit α13 (Gα13). With further validation, our nanovibrational bioreactor could be used to help provide humanised 3D models for drug screening.

Abstract
Background Despite being a common overuse entity in youth soccer, scientific data on risk factors, rehabilitation and return to play for long-standing pubic-related groin pain is still rare. The current prospective cohort study aims to evaluate potential risk-factors, propose a criteria-based conservative rehabilitation protocol and assess return-to-play outcomes among professional youth soccer players suffering from long-standing pubic-related groin pain. Methods Male soccer players with long-standing (> 6 weeks) pubic-related groin pain from a professional soccer club’s youth academy were analyzed for possible risk factors such as age, team (U12 - U23), younger/older age group within the team, position and preinjury Functional movement score. All injured players received a conservative, standardized, supervised, criteria-based, 6-level rehabilitation program. Outcome measures included time to return to play, recurrent groin pain in the follow-up period and clinical results at final follow-up two years after their return to play. Results A total of 14 out of 189 players developed long-standing pubic-related groin pain in the 2017/2018 season (incidence 7.4%). The average age of the players at the time of the injury was 16.1 ± 1.9 years. Risk factor analysis revealed a significant influence of the age group within the team (p = .007). Only players in the younger age group were affected by long-standing pubic-related groin pain, mainly in the first part of the season. Injured players successfully returned to play after an average period of 135.3 ± 83.9 days. Only one player experienced a recurrence of nonspecific symptoms (7.1%) within the follow-up period. The outcome at the 24-month follow-up was excellent for all 14 players. Conclusions Long-standing pubic-related groin pain is an overuse entity with a markedly high prevalence in youth soccer players, resulting in a relevant loss of time in training and match play. In particular, the youngest players in each team are at an elevated risk. Applying a criteria-based rehabilitation protocol resulted in an excellent return-to-play rate, with a very low probability of recurrence. Trial registration The trial was retrospectively registered under DRKS00016510 in the German Clinical Trials Register on 19.04.2021.

Abstract
BACKGROUND Postpartum septic symphysitis (PPSS) is defined as acute onset of severe pain around the symphysis, restricted movement, fever, and elevated inflammatory parameters. It is a rare but serious condition requiring urgent diagnosis and treatment. The aim of this study was to describe the incidence, symptoms, diagnosis, treatment, and long-term follow-up of PPSS. METHODS This follow-up study included 19 out of 21 women diagnosed with PPSS from 1989 to 2017 at one tertiary care hospital in Sweden. Clinical data were retrieved from hospital records and compared to those retrieved from a regional registry. Women completed a postal questionnaire, and those who reported lumbopelvic pain (LPP) were offered a clinical examination. RESULTS 1) PPSS was diagnosed after a normal postpartum period of 24 to 50 h by blood tests (n = 19/19), ultrasonography (n = 9 /19), computer tomography (n = 8/19) or magnetic resonance imaging (n = 16/19) Treatment included aspiration of symphyseal abscesses, i.v. antibiotics and different physiotherapeutic interventions. Women with PPSS more frequently were primiparous (n = 14/19, p = 0.001), had an instrumental delivery (n = 14/19, p = 0.003), longer time of active labour (p = 0.01) and second stage of labour (p = 0.001) than women in the regional registry. 2) Ten out of 19 (52%) women reported LPP at follow-up. These women more often suffered impaired function related to LPP (Pelvic Girdle Questionnaire, 27 versus 0, p < 0.0001), a poorer health-related quality of life (EuroQol-5 dimensions p = 0.001 and EuroQol-visual analogue scale, 65 mm versus 84 mm, p = 0.022) and higher levels of anxiety and depression (Hospital Anxiety Depression Scale (HADS) HADS-Anxiety, 7 versus 2, p = 0.010; and HADS-Depression, 1 versus 0, p = 0.028) than women with no pain. 3). Of the eight women who were clinically assessed, one had lumbar pain and seven had pelvic girdle pain (PGP). CONCLUSIONS In the largest cohort of patients with PPSS to date, primiparas and women with instrumental vaginal delivery were overrepresented, indicating that first and complicated deliveries might be risk factors. Approximately half of the women reported PGP at follow-up, with considerable consequences affecting health-related quality of life and function decades after delivery. Prospective multicentre studies are needed to establish risk factors, long-term consequences, and adequate treatment for this rare pregnancy complication.

Abstract
Background Multiple studies have reported an unacceptable implant-related complication rate in proximal humeral fractures treated with locking plates, particularly in older patients. Our objective was to compare the fracture fixation failure rates in elderly patients, after a dedicated technique for locking plate fixation with cement augmentation or without it. Methods A total of 168 open reduction and internal fixation with locking plates were performed for complex proximal humerus fractures by a single surgeon in 136 women and 32 men older than 65 years of age (average 76 years). Treatment groups included group 1 with noncemented screws (n = 90) and group 2 with cemented screws (n = 78). As per Mayo-FJD Classification, there were 74 (44%) varus posteromedial impaction, 41 (24%) algus impaction, 46 (28%) surgical neck, and 7 (4%) head dislocation injuries. A retrospective radiographic and a clinical analysis was performed. Results At a mean follow-up of 33 months, the implant failure rate was significantly lower in the cement augmentation group (1% vs. 8%, P = .03). The overall complication rate was 21% (25% group 1, 15% group 2; P = .1). Global avascular necrosis was associated with sustaining a valgus impacted fracture (P = .02 odds ratio 5.7), but not to augmentation. Partial avascular necrosis occurred only in patients treated with cemented screws (3.8%). The overall revision rate was 9% in both groups. Forward elevation was 126 ± 36 degrees and external rotation was 44 ± 19 degrees. The mean Constant score was 70 ± 15 in group 1 and 76 ± 15 in group 2 (P = .03). Conclusion Cement augmentation significantly decreased the rate of implant failure. Good results are expected for most patients treated with this technique.

Abstract
Femoroacetabular impingement syndrome (FAIS) has been associated with osteitis pubis; however, it is still unclear whether hip dysplasia is associated with osteitis pubis. This study aimed to investigate (i) the incidence of pubic bone marrow edema (BME) on magnetic resonance imaging in symptomatic patients with FAIS, borderline developmental dysplasia of the hip (BDDH) and developmental dysplasia of the hip (DDH) undergoing hip arthroscopic surgery with labral preservation and (ii) the demographic and radiographic factors associated with pubic BME. A total of 259 symptomatic patients undergoing hip arthroscopic surgery between July 2016 and April 2019 were retrospectively reviewed and divided into three groups: FAIS (180 patients), BDDH (29 patients) and DDH (50 patients). Diffuse changes in the pubic bone adjacent to the pubic symphysis were labeled pubic BME, and the prevalence of their occurrence was examined. Multivariate logistic regression analysis was performed to identify factors involved in pubic BME, and odds ratios (ORs) for relevant factors were calculated. There was no significant difference in the prevalence of pubic BME among the three groups (20 [11.1%] of 180 FAIS patients, 6 [20.6%] of 29 BDDH patients and 7 [14%] of 50 DDH patients, P = 0.325). Multivariate logistic regression analysis showed that acetabular coverage was not associated with pubic BME, whereas younger age and greater alpha angle were still independent associated factors [age ≤26 years (OR, 65.7) and alpha angle ≥73.5° (OR, 4.79)]. Determining the possible association of osteitis pubis with cam impingement in dysplastic hips may provide insights toward a more accurate understanding of its pathophysiology.

Abstract
Background A previous study had reported that patients with osteomyelitis (OM) appeared to be more likely to develop hypocalcemia before and after surgery. Calcium sulfate (CS) is frequently used as a local antibiotic vehicle in the treatment of OM, which may also affect serum calcium level. However, whether changes of serum calcium level are caused by OM and/or local use of calcium sulfate remains unclear. Also, platelet (PLT) count plays a crucial predictive role in periprosthetic joint infections (PJIs), but its role in assisted diagnosis of OM is largely unknown. The purpose of this study was to determine whether serum calcium level and PLT count may be helpful in assisted diagnosis of PTOM. Methods Between January 2013 and December 2018, we analyzed 468 consecutive patients (392 males and 76 females), including 170 patients with posttraumatic OM (PTOM), 130 patients with aseptic bone nonunion (ABN), and 168 patients recovered from fractures with requirement of implant removal set as controls. Preoperative serological levels of calcium, phosphorus, and PLT were detected, and comparisons were conducted among the above three groups. Additionally, correlations and receiver operating characteristic (ROC) curves were displayed to test whether calcium level and PLT can differentiate patients with ABN and PTOM. Results Outcomes showed that the incidences of asymptomatic hypocalcemia (PTOM vs. ABN vs. controls = 22.94% vs. 6.92% vs. 8.82%, χ2 = 21.098, P < 0.001) and thrombocytosis (PTOM vs. ABN vs. controls = 35.3% vs. 13.84% vs. 12.35%, χ2 = 28.512, P < 0.001) were highest in PTOM patients. Besides, the mean serological levels of phosphorus in PTOM and ABN patients were significantly higher than those in the controls (P = 0.007). The Area Under the Curve (AUC) of the ROC curve outcomes revealed that, with the combination of serum calcium level with PLT count, the predictive role was acceptable (AUC 0.730, P < 0.001, 95% CI 0.681-0.780). Also, serological levels of calcium of 2.225 mmol/L and PLT count of 246.5 × 109/L were identified as the optimal cut-off values to distinguish patients with and without PTOM. However, age- and gender-related differences in serum calcium levels (age, P = 0.056; gender, P = 0.978) and PLT count (age, P = 0.363; gender, P = 0.799) were not found to be statistically significant in any groups. In addition, no significant correlations were identified between serum calcium level and PLT count (R = 0.010, P = 0.839). Conclusions Asymptomatic hypocalcemia and thrombocytosis appeared to be more frequent in this cohort with PTOM. Serological levels of calcium and PLT count may be useful biomarkers in screening patients suspected of PTOM.

Abstract
Bristow-Latarjet procedure has been widely regarded as a reliable and satisfactory operation for recurrent anterior glenohumeral instability, especially for patients with significant glenoid bone loss or high sports demand. Once failed, however, the subsequent revision surgery could be challenging. Eden-Hybinette procedure is the most common operation for revision of failed Bristow-Latarjet. It can perfectly restore the bone defect of the failed Bristow-Latarjet by harvesting a proper size of iliac bone block. Furthermore, several studies have shown the advantages of using suture button fixation in the revision surgery for failed Bristow-Latarjet procedure. However, the potential inferior biomechanical strength of suture button fixation is still a concern. This Technical Note introduced an arthroscopic "double-inlay" Eden-Hybinette procedure with modified suture button fixation for the revision of failed Bristow-Latarjet. With its "quadruple" reinforcement effect, this procedure can achieve an excellent biomechanical strength of fixation.

Abstract
Introduction Fracture-related infection (FRI) is a severe post-traumatic complication which is occasionally accompanied by a deficient or even avital soft-tissue envelope. In these cases, a thoroughly planned orthoplastic approach is imperative as a vital and intact soft-tissue envelope is mandatory to achieve fracture union and infection eradication. The aim of this study was, to analyse if soft-tissue reconstruction (STR) without complications is associated with a better long-term outcome compared to FRI patients with STR complications. In particular, it was investigated if primary flap failure represented a risk factor for compromised fracture union and recurrence of infection. Patients and Methods Patients with a lower leg FRI requiring STR (local, pedicled and free flaps) who were treated from 2010-18 at the University Hospital Basel were included in this retrospective analysis. The main outcome measure was the success rate of STR, further outcome measures were fracture nonunion and recurrence of infection. Results Overall, 145 patients with lower leg FRI were identified, of whom 58 (40%) received STR (muscle flaps: n = 38, fascio-cutaneous flaps: n=19; composite osteo-cutaneous flap: n = 1). In total seven patients required secondary STR due to primary flap failure. All failures and flap-related complications occurred within the first three weeks after surgery. Secondary STR was successful in all cases. A high Charlson Comorbidity Index Score was a significant risk factor for flap failure (p = 0.011). Out of the 43 patients who completed the 9-month follow-up, 11 patients presented with fracture nonunion and 12 patients with a recurrent infection. Polymicrobial infection was a significant risk factor for fracture nonunion (p = 0.002). Primary flap failure was neither a risk factor for compromised fracture consolidation (p = 0.590) nor for recurrence of infection (p = 0.508). Conclusion: A considerable number of patients with lower-leg FRI required STR. This patient subgroup is complex and rich in complications and the long-term composite outcome demonstrated a high rate of compromised fracture consolidation and recurrent infections. It appears that secondary STR should be performed, as primary flap failure was neither a risk factor for compromised fracture consolidation nor for recurrence of infection. We propose to monitor these patients closely for three weeks after STR.

Abstract
To induce bone regeneration there is a complex cascade of growth factors. Growth factors such as recombinant BMP-2, BMP-7, and PDGF are FDA-approved therapies in bone regeneration. Although, BMP shows promising results as being an alternative to autograft, it also has its own downfalls. BMP-2 has many adverse effects such as inflammatory complications such as massive soft-tissue swelling that can compromise a patient's airway, ectopic bone formation, and tumor formation. BMP-2 may also be advantageous for patients not willing to give up smoking as it shows bone regeneration success with smokers. BMP-7 is no longer an option for bone regeneration as it has withdrawn off the market. PDGF-BB grafts in studies have shown PDGF had similar fusion rates to autologous grafts and fewer adverse effects. There is also an FDA-approved bioactive molecule for bone regeneration, a peptide P-15. P-15 was found to be effective, safe, and have similar outcomes to autograft at 2 years post-op for cervical radiculopathy due to cervical degenerative disc disease. Growth factors and bioactive molecules show some promising results in bone regeneration, although more research is needed to avoid their adverse effects and learn about the long-term effects of these therapies. There is a need of a bone regeneration method of similar quality of an autograft that is osteoconductive, osteoinductive, and osteogenic. This review covers all FDA-approved bone regeneration therapies such as the "gold standard" autografts, allografts, synthetic bone grafts, and the newer growth factors/bioactive molecules. It also covers international bone grafts not yet approved in the United States and upcoming technologies in bone grafts.

Abstract
STUDY DESIGN This was a retrospective cohort review. OBJECTIVE The objective of this study was to determine the rate of fusion associated with an expandable cage and iliac crest bone graft in minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) surgery. SUMMARY OF BACKGROUND DATA MI-TLIF is a commonly performed procedure, but challenges inherent in MI-TLIF technique can make achieving an interbody fusion difficult. METHODS A retrospective review was performed on consecutive patients treated with an MI-TLIF for degenerative lumbar pathology. Patients that completed patient-reported outcome measures and 1-year computed tomography (CT)-scans for fusion analysis were included. Fusion morphology was analyzed by evaluating CT scans for location of bridging trabecular bone in relation to the cage. Patients with bridging bone were considered fused. Preoperative and postoperative health-related quality of life scores were compared. A Kolmogrov-Smirnoff test was used to determine normality of health-related outcome scores. A Friedman 2-way analysis of variance by ranks with pairwise comparisons to determine statistical significance of differences between the date of a follow-up examination and preoperative examination was done. RESULTS Of 75 patients evaluated 23 patients were excluded due to loss to follow-up, adjacent segment degeneration, inability to obtain a CT scan, or reoperation for nonfusion related symptoms. Of 61 disk spaces that were included, 55 had bridging bone through the intervertebral cage, resulting in an overall fusion rate of 90.2%. There was a higher rate of fusion at L5-S1 as compared to L4-L5. There was mean improvement in patient-reported outcome measures for Oswestry Disability Index, Short Form-12 Physical Component Score, Visual Analog Scale Back/Leg pain, and Patient-Reported Outcome Measurement Information System Physical Function. There were no complications associated with iliac crest bone graft harvesting. CONCLUSION Combining an expandable cage with iliac crest autograft bone harvested through a minimally invasive technique can allow for improved fusion rates without graft-site complications in MI-TLIF surgery.

Abstract
Background The lactate/albumin (L/A) ratio has been proposed as a prognostic marker because the ratio is associated with multiple organ failure and mortality in critically ill patients. We aimed to investigate the clinical utility of the L/A ratio as a good prognostic indicator of mortality in a cohort of necrotizing fasciitis patients. Method This retrospective study was conducted in two tertiary hospitals in Taiwan between 2015 and 2020. We reviewed adult patients with measured serum lactate and albumin on the emergency department (ED) arrival to evaluate the prognostic performance of the lactate and lactate/albumin (L/A) ratio for outcome prediction. Result Of the 262 NF patients, 20 (7.63%) died in the hospital. The area under the receiver operating characteristic curve (AUROC) value of the L/A ratio (0.76, 95% confidence interval [CI] 0.69–0.81, P < 0.01) was higher than lactate alone (0.71, 95% CI 0.65–0.74 P < 0.01) for predicting in-hospital mortality. The optimal cutoff of the L/A ratio was 1.61. The AUROC value of the L/A ratio was better than lactate alone regardless of normal lactate level. The cutoff of L/A ratio and hypoalbuminemia showed further discriminative value for in-hospital mortality even in patients with normal lactate levels. Conclusion The prognostic performance of the L/A ratio was superior to a single measurement of lactate for predicting in-hospital mortality and intensive care unit (ICU) lengths in necrotizing fasciitis patients. Aggressive intervention and intensive care were necessary for high-risk NF patients upon ED arrival.

Abstract
Background Patients with rheumatoid arthritis (RA) are at increased risk of falls and fractures. Sarcopenia occurs more frequently in RA patients due to the inflammatory processes. Early diagnosis and prevention programmes are essential to avoid serious complications. The present study aims to identify risk factors for falls related to sarcopenia and physical performance. Methods In a 1-year prospective study, a total of 289 patients with RA, ages 24–85 years, were followed using quarterly fall diaries to report falls. At the baseline, medical data such as RA disease duration and Disease Activity Score (DAS28CRP) were collected. Self-reported disability was assessed using the Health Assessment Questionnaire (HAQ). Appendicular skeletal mass was determined by Dual X-ray-Absorptiometry (DXA). Physical performance was evaluated by handgrip strength, gait speed, chair rise test, Short Physical Performance Battery, and FICSIT-4. Muscle mechanography was measured with the Leonardo Mechanograph®. Sarcopenia was assessed according to established definitions by the European Working Group on Sarcopenia in Older People (EWGSOP2) and The Foundation for the National Institutes of Health (FNIH). Univariate and multiple logistic regression analysis were used to explore associations with falling. Receiver-operating characteristics (ROC) were performed, and the area under the curve is reported. Results A total of 238 subjects with RA completed the 1-year follow-up, 48 (20.2%) experienced at least one fall during the observational period. No association was found between sarcopenia and prospective falls. Age (OR = 1.04, CI 1.01–1.07), HAQ (OR = 1.62, 1.1–2.38), and low FICSIT-4 score (OR = 2.38, 1.13–5.0) showed significant associations with falls. Conclusions In clinical practice, a fall assessment including age, self-reported activities of daily life and a physical performance measure can identify RA patients at risk of falling. Trial registration The study has been registered at the German Clinical Trials Register and the WHO International Clinical Trials Registry Platform (ICTRP) since 16 March 2017 (DRKS00011873).

Abstract
Bone marrow aspirate concentrate (BMAC) is an autologous cell composition that is obtained through a needle aspiration from the iliac crest. The purpose of this study was to evaluate the outcomes of patients treated with open reduction and internal fixation with BMAC supplementation for clavicle fracture nonunion. This was a retrospective case series of 21 consecutive patients with clavicle fracture nonunion that were treated with ORIF and BMAC supplementation between 2013 and 2020. Patients were evaluated for fracture union, time to union, complications related to surgical and donor site, and functional outcome using the Quick Disability of the Arm Shoulder and Hand (QDASH), subjective shoulder value (SSV), and pain. The mean age was 41.8 years. The mean follow-up was 36 months. Twenty (95.2%) patients demonstrated fracture union, with a mean time to union of 4.5 months. Good functional scores were achieved: SSV, 74.3; QDASH, 23.3; pain level, 3.1. There were no complications or pain related to the iliac crest donor site. Supplementary BMAC to ORIF in the treatment of clavicle fracture nonunion is a safe method, resulting in high rates of fracture union and good functional outcomes with minimal complications and pain.
