To evaluate the functional outcome of open humerus diaphyseal fractures treated with the Three-stitch technique of antegrade humerus nailing. This is a retrospective study conducted at the Department of Orthopaedics in D. Y. Patil University, School of Medicine, Navi Mumbai, India. The study included 25 patients who were operated on from January 2019 to April 2021 and follow-ups done till May 2022. Inclusion criteria were adult patients with open humerus diaphyseal fractures (Gustilo-Anderson Classification). All patients with closed fractures, skeletally immature patients, and patients with associated head injury were excluded from the study. All patients were operated on with a minimally invasive Three-stitch technique for antegrade humerus nailing. All patients were evaluated based on DASH score. Out of the 25 patients included in the study, all patients showed complete union. The mean age of the patients was 40.4 years (range 23–66 years). The average period for consolidation of fracture was 10.56 weeks (range 8–14 weeks). The DASH score ranged from 0 to 15.8 with an average score of 2.96. Five patients reported complications with three patients of post-operative infection and delayed wound healing and two patients with screw loosening. All complications were resolved with proper wound care and the complete union was noted. None of the patients had an iatrogenic neurovascular injury. Three-stitch antegrade nailing technique is a novel method to treat diaphyseal humerus fractures and provides excellent results. It has various advantages such as minimal invasiveness, minimal injury to the rotator cuff, fewer infection rates, minimal iatrogenic injuries, and good functional outcomes. Therefore, this treatment modality can be effectively used for open humerus diaphyseal fractures

Introduction. We aimed to study the rates of both surgical and medical complications associated with femoral diaphysis fracture fixation with intramedullary nailing including all fracture mechanisms. Additionally, we investigated whether the trauma energy has an impact on the complication risk. Method. In this retrospective cohort study, the health records of 491 patients with 503 femoral fractures, who underwent surgery between May 2007 and May 2022 in Tampere University Hospital, were reviewed. Patients who underwent a primary operation with a reamed rigid intramedullary nail for a diaphyseal femoral fracture and whose follow-ups were organized at the same hospital district, were included. Based on those criteria, 57.5% were included for analysis (279 patients with 289 fractures). The complications were then recorded by chart review. To investigate the impact of trauma energy on complication risk, we compared complication proportions in high- and low-energy groups and calculated odds ratios. Result. The crude percentage of 30-day mortality was 2.1% (6 of 289) based on information obtained from the patients’ records. The overall proportion of complications was 22.5%. The risk of any medical complication was 2.8%, whereas the risk of surgical complication was 19.8%. The risk of complications was nearly twice as high in high-energy fractures compared to low-energy fractures, with an odds ratio (OR) of 1.92, 95% CI 1.03-3.75. The risk of reoperations was significantly increased in high-energy traumas (OR 2.46, CI 1.25-5.24). Conclusion. This study reveals a 2.1% risk of thirdy-day mortality and a 22.5% risk of overall complications, predominantly of a surgical type. The complication risk, especially the risk of surgical complications, is higher among the patients with fractures caused by high-energy injury compared to low-energy fractures, highlighting the importance of timely identification of those complications for providing better postoperative care

Introduction and Purpose. Metacarpal fractures constitute approximately one third of all hand fractures. The majority of these fractures are treated by conservative non-surgical methods. The aim of this study is to obtain the appropriate anatomical alignment of the fracture with dynamic metacarpal stabilization splint (DMSS) and to maintain the proper bone anatomy until the union is achieved. In addition, by comparing this method with short arm plaster splint (SAPS) application, it is aimed to evaluate whether patients are superior in terms of comfort, range of motion (ROM) and grip strength. Materials and Methods. In our study, SAPS or DMSS was applied to the patients with 5th metacarpal neck fracture randomly after fracture reduction and followed for 3 months. A total of 119 patients with appropriate criteria were included in the study. Radiological alignment of the fracture and amount of joint movements were evaluated during follow-up. Grip strength was evaluated with Jamar dynamometer. EQ-5D-5L and VAS scores were used for clinical evaluation. Results. 103 patients completed their follow-up. 51 patients were treated with SAPS and 52 patients were treated with DMSS. The mean age of the SAPS was 29.5 (SD ± 9.4; 16–53 years) and the mean age of the DMSS group was 27.8 (SD ± 11.6; 16–63). Pressure sores was seen in 5 patients in the DMSS group, while no pressure sore was seen in the SAPS (p = 0.008). There was no significant difference between the two groups in the VAS scores at all times. There was no significant difference between the mean dorsal cortical angulation (DCA) before the reduction, after the reduction and at the third month follow-ups. There was no statistically significant difference between the length of metacarps at first admittion before reduction, after reduction and at third month follow-ups. When the grip strength of the two groups were compared as a percentage, the grip strength of the patients in the DMSS group was found to be higher at 1st month, 2nd month and 3rd month (p <0.001). When the ROM values of the patients were evaluated, DMSS group had a higher degree of ROM in the first month compared to the SAPS group (p <0.001). No statistically significant difference was detected among groups at third month in the ROM of the IP and MP joints. However, wrist ROM was statistically higher in DMSS group at 3rd month (p <0.05). There was a statistically significant difference between EuroQol scores in favor of DMSA group (p <0.05). Discussion and Conclusion. In stable 5th metacarpal neck fractures, DMSA is as effective as SAPS to maintain bone anatomy. In addition, DMSA can be preferred for fixation plaster splint or circular plaster applications for the prevention of reduction in boxer fractures, with the advantage of having high clinical scores, which is an indication of early acquisition of grip strength, ease of use and patient comfort

Barriers to successful return to previous level of activity following Anterior Cruciate Ligament Recon-struction (ACLR) are multifactorial and recent research suggests that athletic performance deficits persist after completion of the rehabilitation course in a large percentage of patients. Thirty soccer athletes (26.9 ± 5.7 years old, male) with ACL injury were surgically treated with all-inside technique and semitendi-nosus tendon autograft. At 2 years from surgery, they were called back for clinical examination, self-reported psychological scores, and biomechanical outcomes (balance, strength, agility and velocity, and symmetry). Nonparametric statistical tests have been adopted for group comparisons in terms of age, concomitant presence of meniscus tear, injury on dominant leg, presence of knee laxity, presence of varus/valgus, body sides, and return to different levels of sports. Athletes with lower psychological scores showed lesser values in terms of power, resistance and neuromuscular activity as compared to the ones with good psychological scores that showed, instead, better self-reported outcomes (TLKS, CRSQ) and low fear of reinjury (TSK). In the athletes who had a functional deficit in at least one subtest, a safe return to sports could not have been recommended. Our findings confirmed that demographics, physical function, and psychological factors were related to playing the preinjury level sport at mean 2 years after surgery, sup-porting the notion that returning to sport after surgery is multifactorial. A strict qualitative and quantitative assessment of athletes’ status should be performed at different follow-ups after surgery to guarantee a safe and controlled RTP

Muscle and tendon have an adaptive, symbiotic biomechanical relationship that is drastically altered following acute tendon injury. Such injuries, like Achilles tendon rupture (ATR), do not only lead to impairments in the resultant tendinous tissue, but also to irrecoverable atrophy in the connected muscle in series. As a result, a new relationship between muscle and tendon is established after ATR, leading to lasting functional deficits in the lower limb. It remains unclear how these develop, particularly since this imbalance may be influenced by the dependent relationship of the two tissues to each other. A further confounding factor is that tendon and muscle tissues adapt on different time scales in response to mechanical loading, such as those introduced during rehabilitation. Thus, it is warranted to perform assessments not only of the overall muscle-tendon unit, but also its constituent tissues. This presentation will discuss findings from both short-term and long-term follow-ups of ATR patients, with a focus on the recovery of gait and changes in the muscle-tendon unit tissues following ATR repair. Both the influence of the rehabilitation process and suggestions for future research directions will be additionally presented

Supracondylar fractures of the humerus (SCFH) are the most common type of paediatric elbow fractures. Due to beliefs that non-operatively managed SCFH may displace further from the original position, they are monitored with repeated radiographs and a large number are unnecessarily surgically pinned. Very limited evidence currently exists to support these beliefs. This study aimed to determine the incidence of late “significant” displacement (requiring surgical management) of non-operatively managed paediatric SCFH, and whether they necessitate close radiographic follow-up. Patients aged ≤16, with a SCFH, were included in this retrospective cohort study. All were initially managed non-operatively with at least one follow-up radiograph within six weeks of injury. Data from four consecutive years (2013–2016) was collected using the hospital's radiology database. Two observers independently analysed patient radiographs and classified fractures by the Gartland and AO systems. The incidence of late displacement was determined using follow-up radiographs and clinic notes. Of the 164 patients included in the study, one patient (Gartland Type II, AO Type III) suffered late displacement at two weeks, requiring surgical fixation. One further patient (AO Type II) had a persistent cubitus varus deformity (Baumann's angle 90°), with no long-term functional deficit. Incidence of late displacement was 0.6% (n=1). Our findings suggest that stable Gartland Type I/AO Type I and II fractures do not require repeated radiographic follow-up. However, some Gartland Type II/AO Type III fractures require monitoring. This could considerably reduce the financial costs for the healthcare system, and inconvenience to families, associated with repeated follow-ups

Acute lateral ankle sprain accounts for 85% of sprains. The lateral sprain is associated with other ligament injuries e.g. medial and syndesmosis sprain. Long-term, approximately 20% of acute lateral sprains develop into chronic lateral ankle instability (CLAI) which includes persistent pain, and recurring ankle sprains. This study evaluated the grade of an ankle ligament injury by ultrasonography (US) and compared the findings to the outcome of patient-reported questionnaires. 48 subjects (18–40 years) diagnosed with an ankle sprain attended a clinical and US examination of ankle ligaments within two weeks after the sprain. Evaluation was done by US of acute lateral ligament injuries (ATFL, CFL), syndesmosis injury (AiTFL), and medial injury (dPT, TCt) only in participants with the positive clinical signs of medial injury. Participants were then mailed a questionnaire (PROMQ) every third month for a year. 29 women and 19 men participated with a mean age at 26.50 years. One-year follow-ups need to be analyzed further for final results. Temporary results include data based on the initial 26 patients: Two clinical signs statistically correlated. Multiple logistic regression analysis confirmed the results. Positive palpated tenderness AiTFL predicted with partial ruptured ATFL and reported pain during active plantar flexion of ankle predicted with normal CFL confirmed by the US. Patients with partial rupture of ATFL presented with tenderness at AiTFL point. Patients presenting with intact CFL reported pain during active plantar flexion. Compared to the US findings, the overall examinations were inconclusive in predicting ATFL, CFL, AiTFL, and medial ligament injuries

Background. Innovative developments for total knee arthroplasty enhanced anatomical design and fixation in order to decrease particle-induced aseptic implant loosening. As hypersensitivity reactions to metallic implant materials have been recognized to possibly cause premature implant failure, ceramic materials might constitute a proper alternative solution. The aim of this prospective short-term study was the initial comparison of a completely metal-free ceramic with a geometrically identical metallic arthroplasty over a one-year follow-up period. Methods. Eighty patients requiring primary total knee arthroplasty were enrolled within this open-label prospective comparative study. Patients were randomly divided among two groups to either undergo implantation of a completely metal-free system using a composite matrix material containing aluminum oxide (Al2O3) and zirconium oxide (ZrO2) (n=40), or an anatomically identical metallic knee system made of a cobalt-chromium alloy (Co28Cr6Mo) (n=40) produced by the same manufacturer. Clinical assessment was performed preoperatively, and during follow-up at three and twelve months using the Knee Society Score, Oxford Knee Score and EQ-5D-VAS. For radiological evaluation, standard preoperative and postoperative standardized radiographs were taken at mentioned follow-up visits. Results. Demographical data were not significantly different among our two study groups, and no patient has been lost to follow-up. The postoperative clinical scores improved significantly at three and twelve month follow-ups, but did not differ statistically among groups. The radiologically evaluated mean postoperative mechanical and anatomical axes showed proper alignment within both groups at all times. Notably, no revision surgery had to be performed, and no complications were recorded whatsoever. Conclusion. To our knowledge, this is the first study comparing a total ceramic metal-free knee system with a geometrically identical metallic TKR. Within the short-term follow-up of minimally one year, no significant differences could be demonstrated clinically or radiologically, therefore making this ceramic knee system a suitable option for patients with a known hypersensitivity to metal. Mid-term and long-term studies will be required to demonstrate the overall efficiency of this TKR to potentially expand its medical indication

Background. Delayed bone healing and nonunion are complications of long bone fractures, with prolonged pain and disability. Regenerative therapies employing mesenchymal stromal cells (MSC) and/or bone substitutes are increasingly applied to enhance bone consolidation. Within the REBORNE project, a multi-center orthopaedic clinical trial was focused on the evaluation of efficacy of expanded autologous bone marrow (BM) derived MSC combined with a CaP-biomaterial to enhance bone healing in patients with nonunion of diaphyseal fractures. To complement the clinical and radiological examination of patients, bone turnover markers (BTM) were assayed as potential predictors of bone healing or non-union. Methods. Bone-specific alkaline phosphatase (BAP), C-terminal-propeptide type I-procollagen (PICP), osteocalcin (OC), β-Cross-Laps Collagen (CTX), soluble receptor activator of NFkB (RANKL), osteoprotegerin (OPG) were measured by ELISA assays in blood samples of 22 patients at BM collection and at follow-ups (6, 12 and 24 weeks post-surgery). Results. A significant relationship with age was found only at Visit 6, with an inverse correlation for CTX, RANKL and OC, and positive for OPG. BTM levels were not related to gender. As an effect of local regenerative process, some BTM showed significant changes in comparison to the starting value. In particular, the time course of BAP, PICP and RANKL was different in patients with a successful healing in comparison to patients with negative outcome. The BTM profile indicated remarkable bone formation activity after 12 weeks after surgery. However, the paucity of failed patients in our case series did not allow to prove statistically the role of BTM as predictors of the final outcome. Conclusion. BTM related to bone cell function are useful to measure the efficacy of a regenerative approach based on expanded MSC. Level of evidence. Diagnostic Level IV.

Summary Statement. The current biomecahnical study demonstrated that the stemless peripheral leg humeral component prototype and central screw humeral component prototype achieved similar initial fixation as stemmed Global Advantage humeral component in terms of resultant micromotion in total shoulder arthroplasty. Introduction. A stemless humeral component may offer a variety of advantages over its stemmed counterpart, e.g. easier implantation, preservation of humeral bone stock, fewer humeral complications, etc. However, the initial fixation of a stemless humeral component typically depends on cementless metaphyseal press-fit, which could pose some challenges to the initial stability. Long-term success of cementless implants is highly related to osseous integration, which is affected by initial implant-bone interface motion. 1. The purpose of the study was to biomechanically compare micromotion at the implant-bone interface of three humeral components in total shoulder arthroplasty. Patients & Methods. Three humeral components were evaluated: Global Advantage, a central screw prototype, and a peripheral leg prototype. All components were the smallest sizes available. Global Advantage is a stemmed design. Both central screw prototype and peripheral leg prototype are stemless designs. Five specimens were tested for each design. Composite analogue humeral models were utilized to simulate the humeral bone. The cortical wall had a thickness of 3 mm and a density of 481 kg/m. 3. , while the cancellous density was 80 kg/m. 3. The model was custom fabricated to accommodate 40 mm humeral component and had a 45° resected surface and a square base to facilitate test setup. Each humeral component was implanted per its surgical technique. The construct was clamped in a vise with the humeral shaft angled at 27°. A MTS test system was employed to conduct the test. A sinusoidal compressive load from 157 N to 1566 N (2BW) was applied to the humeral component at 1 Hz for 100 cycles. The implant-bone interface micromotion was measured with a digital image correlation system which had a resolution of less than 1 micron. The micromotion measurement was transformed to 2 components: 1 was parallel and the other perpendicular to the humeral resection surface. Peak-valley micromotion from the last 10 cycles were averaged and utilised for data analyses. A one-way ANOVA and post-hoc Tukey tests were performed to compare the micromotion of different designs (α=0.05). Results. Micromotion of Global Advantage parallel to the resection (X-Axis) was significantly less than that of central screw prototype and peripheral leg prototype. Micromotion of peripheral leg prototype perpendicular to the resection (Y-Axis) was significantly less than Global Advantage and central screw prototype. There was no significant difference between different designs in resultant micromotion. Discussion/Conclusion. Clinical studies have shown that current stemless shoulder prosthesis yielded encouraging results in mid-term follow-ups. Particularly, the stemless Arthrex Eclipse humeral component, a central screw design, has been reported to have a secure bony fixation and ingrowth at an average of 23 months postoperatively. 4. The current study demonstrated that the stemless peripheral leg prototype and central screw prototype achieved similar initial fixation as stemmed Global Advantage in terms of resultant micromotion, and provided biomechanical evidence that stemless humeral components could have comparable initial stability to stemmed counterparts

Objectives

To explore the therapeutic potential of combining bone marrow-derived mesenchymal stem cells (BM-MSCs) and hydroxyapatite (HA) granules to treat nonunion of the long bone.

Methods

Ten patients with an atrophic nonunion of a long bone fracture were selectively divided into two groups. Five subjects in the treatment group were treated with the combination of 15 million autologous BM-MSCs, 5g/cm3 (HA) granules and internal fixation. Control subjects were treated with iliac crest autograft, 5g/cm3 HA granules and internal fixation. The outcomes measured were post-operative pain (visual analogue scale), level of functionality (LEFS and DASH), and radiograph assessment.
