Managing severe bipolar bone loss in athletes: A comprehensive approach with open Latarjet and arthroscopic remplissage.

Background: Severe bipolar bone loss (BBL) represents one of the toughest challenges when managing the instability of glenohumeral joints among athletes and more specifically the ones involved in overhead sports. It refers to the significant loss of the humeral head and the glenoid bone, with an increased risk of failure. The present study aimed to evaluate the functional outcomes of a combined open Latarjet and arthroscopic remplissage in such high-risk individuals. Methods: A retrospective evaluation was carried out among athletes with antero-inferior loss of glenoid bone of more than 15 % and large off-track Hill-Sachs defect who underwent the Latarjet technique with iliac crest bone graft (ICBG) harvest used in combination with arthroscopic remplissage between 2021 and 2023. The University of California, Los Angeles (UCLA) score, constant-Murley score (CMS), and the range of motion (ROM; measured as forward flexion, external rotation, and abduction) were evaluated pre-operative and post-operative at the timepoint of 3-month, 6-month, and 1-year. Pre-operative magnetic resonance imaging scans (MRI) and computed tomography scans (CT) were obtained among the patients with severe glenohumeral BBL, and the glenoid track was calculated to identify on-track and off-track Hill-Sachs lesions. Post-operative MRI with filled Hill-Sachs defect post remplissage procedure and 3D CT scan was also done at 6-month to evaluate the union of the ICBG to the native glenoid bone. Results: Overall, 11 patients underwent for the combined procedure for severe BBL. The UCLA score (31.18 ± 3.74), and the CMS (93.64 ± 8.38) at the time-point of 1-year post-operatively showed remarkable improvement in comparison with the preoperative scores (P < 0.0001); and the ROM including abduction, external rotation, and forward flexion were restored to near normality. All patients showed bony union at 6-month as confirmed by post-operative CT scan. No complications such as redislocation or subluxation were observed over 1-year. There were no neurological complications or complications related to graft (graft migration or graft breakage or resorption) as well. All the athletes returned to sports activities at an average duration of 6.8-month post-operatively, with 73 % returning to sports at the level of pre-injury. Conclusion: The combined procedure of ICBG Latarjet and arthroscopic remplissage for the treatment of severe BBL in athletes achieved satisfactory outcomes over 1-year, with all athletes returning to sports activities.

Average Indian Glenoid Sizes Are Smaller than All Commercially Available Glenoid Components: A Systematic Review.

Background: Despite the variability in glenoid sizes geographically, most of the currently available commercial glenoid component designs are based on the glenoid parameters of the Caucasian population which may not be suitable for the Indian population due to a mismatch between the prosthesis and native anatomy. The aim of the present study is to systematically review the literature to determine the average glenoid anthropometric parameters in the Indian population. Methods: A comprehensive literature search was conducted using preferred reporting items for systematic reviews and meta-analyses guidelines in the PubMed, EMBASE, Google Scholar, and Cochrane Library databases from the date of inception to May 2021. Any observational study conducted on the Indian population measuring the glenoid diameters, glenoid index, version, inclination, or any other glenoid measurements were included in the review. Results: A total of 38 studies were included in this review. The glenoid parameters were assessed on intact cadaveric scapulae in 33 studies, on 3DCT in three studies, and 2DCT in one study. The pooled average of glenoid dimensions are as the following- the superoinferior diameter or height was 34.65 mm, anteroposterior1 diameter or maximum width was 23.72 mm, anteroposterior2 diameter or maximum width of the upper part of the glenoid was 17.05 mm, the glenoid index was 67.88, and the glenoid version was 1.75-degree retroversion. Males were having a mean height of 3.65 mm and maximum width of 2.74 mm larger than the females. A subgroup analysis revealed no significant difference between different parts of India in glenoid parameters. Conclusion: The glenoid dimensions in the Indian population are smaller compared to the average European and American populations. The average glenoid maximum width of the Indian population is 1.3 mm smaller than the minimum glenoid baseplate size available in reverse shoulder arthroplasty. Glenoid components specific to the Indian market need to be designed to reduce glenoid failure attributable to the above findings. Level of evidence: III.

Augmentation with Fibertape Leads to Biomechanically Superior but Similar Clinical Outcomes in ACL Surgeries: Systematic Review and Meta-analysis.

Purpose: The current generation has witnessed significant progress in the field of knee arthroscopy. Suture tapes have gained immense popularity due to perceived improved biomechanical support to the graft while it heals. The purpose of the present systematic review is to analyze the biomechanical construct of suture tapes in ACL repairs and reconstructions along with clinical outcomes. Methods: Cochrane Library, PubMed, and Embase were searched until December 2021. All Biomechanical Studies on animal or cadaver knees that compared construct characteristics of suture tape in ACL repair or reconstruction and clinical studies in English focusing on outcomes following suture tape augmentation in ACL repair or reconstruction were included. The quality of clinical studies using the Modified Coleman Methodology Score (MCMS). Results: A total of 16 studies biomechanical and 23 clinical studies were included in qualitative synthesis, leaving nine biomechanical studies for final quantitative analyses. Suture tape revealed biomechanical superiority in terms of ultimate strength, stiffness, cyclic displacement, and elongation of graft, while comparing ACLR with internal brace to standard ACLR. No significant difference in retear rates was seen in clinical studies. Clinical score(IKDC score) was found similar in both augmented and non-augmented construct. Similar results were obtained in biomechanical studies. Conclusion: The use of suture tape as a ligament augmentation in both ACL reconstruction and ACL repair offers more strength, less elongation or displacement, and is biomechanically stable and sound. There is a lack of data to comprehensively comment upon the clinical superiority of the use of internal augmentation. However, a meta-analysis of the retear rates and clinical outcome score revealed similar outcomes between suture tape augmented and nonaugmented groups.

Peroneus Longus Graft Harvest: A Technique Note.

Multiple graft options are available for knee ligament surgeries, one of the latest being peroneus longus grafts. Despite, an increasing usage of PL for graft harvest there is a scarcity of technique guides for its harvest, finding mention in only a few case studies. The following is a technical note dedicated to peroneous longus graft harvest. Supplementary Information: The online version contains supplementary material available at 10.1007/s43465-023-00847-0.

A cross sectional survey exploring the awareness and familiarity regarding patient reported outcome measures (PROMs) among joint reconstruction surgeons in India.

Background: The aim of this study is to describe the usage of PROM, its use or lack of use, barriers in using it and its future prospect among the arthroplasty surgeons from a developing country like India. Methods: An online survey was conducted by emailing an anonymous questionnaire to orthopaedic surgeons working in three tertiary care academic institutions and two tertiary care private hospitals. All orthopaedic surgeons or residents who have been performing or assisting in arthroplasty and arthroscopy were included in the study. The study was cross-sectional in design based on a single response from all surgeons. Results: The mean age of the 87 surgeons participating in this study was 38.6 ± 4.7 years. 62.1% of surgeons had used PROMs for both clinical as well as research purposes at some point. 25.9% of surgeons had an adequate understanding of the function, benefits, and drawbacks of PROMs. Among the barriers against using PROMs, time constraint was agreed upon by most of the surgeons (59.5%). 64.3% of surgeons were willing to incorporate the PROMs into their daily practice if the barriers are overcome. Conclusion: The limitations of use of PROM should also be borne in mind before embarking on its widespread implementation. Involvement of regulatory and professional societies as well as substantial investment in manpower, money and time is required for making the use of PROMs regular.

A Prospective Observational Study on Short-Term Functional Outcome of Arthroscopic Anterior Cruciate Ligament Repair of Proximal Tears Using Knotless Single Suture Anchor Technique.

PURPOSE: To assess the clinical outcomes in patients with anterior cruciate ligament (ACL) proximal tears undergoing arthroscopic primary repair with knotless single suture anchor technique. METHODS: The first twenty-two consecutive patients with proximal ACL tears (Sherman types I and II and high-grade partial tears) treated with arthroscopic primary repair with single suture anchor technique were evaluated until 6 months post-operatively. Patients were evaluated with validated functional outcome measures (IKDC and Lysholm scores) and clinical tests for ACL stability. RESULTS: At 6-month follow-up, 91% of patients (n = 20) achieved excellent outcome measures for IKDC and Lysholm scores and had complete stability of the ACL to clinical testing. Two patients with poor outcomes at six weeks; one with subjective instability and the other underwent revision surgery represented a failure rate of 9%. The median Lysholm score was 96 (IQ range, 96-100) and median IKDC subjective score was 87.40 (IQ range, 78.20-88.50) at 6-month follow-up. The improvement in Lysholm and IKDC scores over a period of six months post-operatively was statistically significant when compared to preoperative scores (p ≪ 0.0001). Maximum improvement in clinical outcomes is achieved in the first 6 weeks post-surgery with a slower increase thereafter, a time interval which may be considered as a figurative yield point for future work in this field. CONCLUSION: Arthroscopic ACL primary repair with knotless single suture anchor technique provides excellent short-term clinical outcomes in a carefully selected subset of patients with proximal ACL tears. More powered and longer duration studies are needed to understand longer term outcomes. LEVEL OF EVIDENCE: Level IV, therapeutic case series.

Dissociation of the Glenosphere: A rare Post-operative Complication of Reverse shoulder Replacement.

INTRODUCTION: Reverse shoulder replacement (RSR) has been accepted as the treatment of choice for glenohumeral arthritis with irreparable rotator cuff tear. Dislocation has been a potential complication of RSR but glenosphere disengagement is a rare complication itself. There have been only few published reports of this complication in the literature. CASE REPORT: In this case report, we have presented a case of repeated disengagement of glenoid sphere post-RSR in a 72-year-old male retired army personnel operated with Zimmer Biomet comprehensive RSR design. CONCLUSION: In our case scenario, we postulate that soft-tissue interposition was the reason for disengagement during first episode and was successfully relocated after removal. However, the subsequent disengagement was due to improper seating of sphere due to large central screw. Revision to a smaller central screw size appears to be the definitive solution in such case.

Radiofrequency Microdebridement as an Adjunct to Arthroscopic Surgical Treatment for Recalcitrant Gluteal Tendinopathy: A Double-Blind, Randomized Controlled Trial.

BACKGROUND: Recalcitrant greater trochanteric pain is increasingly recognized as an indication for surgical intervention. The arthroscopic approach has become rapidly more common than the open alternative. HYPOTHESIS: Patients undergoing radiofrequency microdebridement (RFMD) as an adjunct to arthroscopic gluteal bursectomy (AGB) and iliotibial band release (ITBR) will experience better functional improvement than AGB and ITBR alone at 1 year. STUDY DESIGN: Randomized controlled trial; Level of evidence, 2. METHODS: A total of 33 patients with failed nonoperative treatment of gluteal tendinopathy were randomly allocated to undergo AGB/ITBR or AGB/ITBR + RFMD. Full-thickness tears were excluded. The primary outcome measure was the modified Harris Hip Score (mHHS) at 52 weeks. Secondary outcome measures included the mHHS, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analog scale (VAS) for pain, and 12-item Short Form Health Survey (SF-12), which were evaluated at 0, 6, 12, 24, and 52 weeks. Statistical significance was defined as P < .05. RESULTS: A total of 33 participants (33 hips; 30 female and 3 male; mean age, 58 years) were randomized; 16 patients underwent AGB/ITBR + RFMD, and 17 underwent AGB/ITBR. Participants' functionality improved in both groups at all time intervals. The mean mHHS score improved from 57.49 ± 10.61 to 77.76 ± 18.40 (P = .004) and from 58.98 ± 12.33 to 79.96 ± 18.86 (P = .001) at 52 weeks in the AGB/ITBR and AGB/ITBR + RFMD groups, respectively, although there was no statistically significant difference between groups. There were no device-related adverse events. CONCLUSION: AGB/ITBR led to significant improvements in patients with recalcitrant gluteal tendinopathy. In this small RCT, the addition of RFMD showed no additional benefit to AGB/ITBR but provided a safe adjunct for the surgical management of recalcitrant gluteal tendinopathy.

An overview of thermal necrosis: present and future.

Introduction: Many orthopaedic procedures require drilling of bone, especially fracture repair cases. Bone drilling results in heat generation due to the friction between the bone and the drill bit. A high-level of heat generation kills bone cells. Bone cell death results in resorption of bone around bone screws.Methods: We searched in the literature for data on parameters that influence drilling bone and could lead to thermal necrosis. The points of view of many orthopaedists and neurosurgeons based upon on previous practices and clinical experience are presented.Results: Several potential complications that lead to thermal necrosis are discussed and highlighted.Discussion: Even in the face of growing evidence as to the negative effects of heat induction during drilling, simple and effective methods for monitoring and cooling in real-time are not in widespread usage today. For that purpose, we propose some suggestions for the future of bone drilling, taking note of recent advances in autonomous robotics, intelligent systems and computer simulation techniques.Conclusions: These advances in prevention of thermal necrosis during bone drilling surgery are expected to reduce the risk of patient injury and costs for the health service.

Platelet-Rich Plasma Has Better Long-Term Results Than Corticosteroids or Placebo for Chronic Plantar Fasciitis: Randomized Control Trial.

Plantar fasciitis is the most common cause of heel pain. Platelet-rich plasma (PRP) is a supersaturated concentration of autologous platelets that augments the natural healing response of fascia. Previous studies have shown the superiority of PRP over corticosteroids (CS) for chronic plantar fasciitis. The aim of this study was to compare the pain and functional outcomes of PRP with CS and placebo injections for the treatment of chronic plantar fasciitis. We conducted a 3-arm randomized controlled trial of 90 patients: PRP (n = 30 patients), CS (n = 30 patients), and placebo (n = 30 patients). The patients were followed at regular intervals until 18 months postinjection using validated instruments. The mean visual analog scale score showed significant improvement in all groups between baseline and 18-month follow-up (PRP: 8.2 vs 2.1; CS: 8.8 vs 3.6; placebo: 8.1 vs 5.4), with CS showing significantly better improvement than PRP in the short term, whereas longer-term PRP was significantly better than CS. The mean Roles and Maudley score showed significant improvement in all groups between baseline and 18-month follow-up (PRP: 1.7 vs 3.7; CS: 1.2 vs 3.1; placebo: 1.2 vs 2.0), with CS showing significantly better improvement than PRP in the short term, whereas longer-term PRP was significantly better than CS. The mean Short Form 12 score showed significant improvement in all groups between baseline and 18-month follow-up (PRP: 55.4 vs 80.2; CS: 56.2 vs 76.2; placebo: 54.1 vs 62.4). We found that all 3 groups showed significant improvement between baseline and end of the follow-up period with regard to pain, function, and general health. The CS arm showed better improvement in the short term, whereas the PRP arm showed better results in the long term. In contrast to previous studies, we found no significant drop-off effect of CS in the long term, which may be owing to background natural healing process of the disease. In summary, both PRP and CS are safe and effective treatment options for chronic plantar fasciitis, showing superior results to placebo treatment. The longer-term results and less reinjection and/or surgery rate of PRP makes it more attractive as an injection treatment option versus CS injection.

A novel and simple classification for ligamentum teres pathology based on joint hypermobility.

Ligamentum teres (LT) pathology (including synovitis, partial and complete tears) is common at the time of hip arthroscopy with a reported prevalence of 51-90%. Currently, there are four published classifications of LT injuries and tears. The majority focuses on differentiating partial from full thickness tears, whereas a more recently published classification also incorporates the presumed underlying mechanism of pathology. A recent review of the current classification systems found that all are deficient for lack of inclusion of what constitutes a normal ligament, lack of inclusion of synovitis as a source of pathology and lack of inclusion of hypermobility as part of the treatment algorithm. Also, the two most commonly used classification systems have only fair inter-observer reliability. Recent work has found that underlying joint hypermobility plays an important role in LT pathology and that the addition of capsular plication/suture at the time of surgery for LT pathology improves outcomes and reduces re-tear rates. In order to address these problems which have been identified with the currently available classification systems, we propose a novel and simple classification for LT pathology based on underlying joint hypermobility [as assessed by the Beighton test score (BTS)]. LT pathology is used to divide all patients into four types: 0 normal (which includes minor fraying), 1 synovitis (which would also include minor fraying), 2 partial tear and 3 complete tear. Further, all types are subdivided into two groups: Group A patients have no clinical evidence of joint hypermobility (BTS < 3), whereas Group B patients do have clinical evidence of joint hypermobility (BTS ≥ 4). On the basis of this classification system and the available literature, we have also developed a treatment algorithm for LT pathology.

The role of the ligamentum teres in the adult hip: redundant or relevant? A review.

The ligamentum teres (LT) has traditionally been described as a redundant structure with no contribution to hip biomechanics or function. There has been renewed interest in the LT as a source of hip pathology due to the high prevalence of LT pathology observed at the time of hip arthroscopy. The LT acts a secondary stabilizer to supplement the work of the capsular ligaments and works in a sling-like manner to prevent subluxation of the hip at the extremes of motion. The presence of free nerve endings within the LT indicates a definite role in pain generation, with the LT undergoing various mechanical and histological adaptations to hip pathology.

Optimal parameters to avoid thermal necrosis during bone drilling: A finite element analysis.

The drilling bone may potentially cause excessive frictional heat, which can lead to local bone necrosis. This heat generation and local necrosis has been suggested to contribute to the resorption of bone around the placed screws, ending in loss of screw purchase in the bone and inadvertent loosening and/or the bone-implant construct. In vivo studies on this subject have inherent obstacles not the least of which is controlling the variables and real time bone temperature data acquisition. Theoretical models can be generated using computer software and the inclusion of known constants for the mechanical properties of metal and bone. These known Data points for the variables (drill bit and bone) enables finite element analysis of various bone drilling scenarios. An elastic-plastic three-dimensional (3D) acetabular bone mode was developed and finite element model analysis (FEA) was applied to various simulated drilling procedures. The FEA results clearly indicate that the depth of drilling and the drill speed both have a significant effect on the temperature during drilling procedures. The reduction of the feeding speed leads to a reduction in bone temperature. Our data suggests that reducing the feeding speed regardless of RPMs and pressure applied could be a simple useful and effective way to reduce drilling temperatures. This study is the first step in helping any surgeon who drills bone and places screws to better understand the ideal pressure to apply and drill speed to employ and advance rate to avoid osteonecrosis. © 2017 Orthopaedic Research Society.

Bone morphogenetic protein-7: Review of signalling and efficacy in fracture healing.

Bone morphogenetic proteins (BMPs) are a group of signalling molecules that belong to the transforming growth factor-ß superfamily of proteins. Initially identified for their ability to induce bone formation, recent advances in the understanding of cellular and molecular mechanisms regarding BMPs have led to the use of the growth factor to accelerate bone healing. Recent clinical trials have demonstrated that BMPs, BMP-7 in particular, may present an alternative line of treatment other than the gold standard, autogenous bone grafting, in the treatment of fracture nonunion. We performed a literature search in September 2014 of PubMed and Embase using search terms, including "bone morphogenetic proteins", "BMP-7", "non-union", "fracture healing" and "cost-effectiveness", reviewing the efficacy, safety, and cost of treatment of nonunions with BMP-7. The authors further canvassed the reference lists of selected articles and used online search tools, such as Google Scholar. BMP-7 uses both the canonical and noncanonical signalling pathways. The treatment of fracture nonunion with recombinant human BMP-7 (rhBMP-7) has a comparable efficacy with that of autogenous bone grafting with an average union rate of 87% compared with 93% for bone grafting. Furthermore, fewer complications have been described with the use of rhBMP-7 compared with traditional bone grafting. We describe the signalling pathways that BMP-7 uses to exert its effect on bone. In nonunions, rhBMP-7 has been shown to have a similar efficacy to bone grafting with fewer complications.

Glyceryl trinitrate patches-An alternative treatment for shoulder impingement syndrome.

Transdermal glyceryl trinitrate patches have been investigated as an alternative therapeutic intervention for a range of tendinopathies, due to the ease of titration of dosage and the ease of their application. Glyceryl trinitrate has been inferred to reduce pain and inflammation secondary to their nitric oxide-producing action. Shoulder impingement syndrome is a soft tissue condition that manifests as anterior shoulder pain, weakness, and difficulty in daily activities. This review will evaluate the efficacy of glyceryl trinitrate patches in treating a variety of rotator cuff tendinopathies related to shoulder impingement, based on human and animal trials, and suggest its practical application in future trials and management.

A rare case of ipsilateral shoulder and thumb CMC joint neuropathic arthropathy.

Neuropathic arthropathy (Charcot joints) most frequently affect the weight-bearing joints of the body, are commonly associated with a variety of medical and neurological conditions and are notoriously difficult to treat due to the nature of the underlying pathology. We present a case of ipsilateral shoulder and thumb carpometacarpal (CMC) joint neuropathic arthropathy secondary to cervical syringomyelia. To our knowledge, this is the first reported case in the literature of this rare association.

Australian medical students and their choice of surgery as a career: a review.

BACKGROUND: Surgery is an emotionally, physically and mentally challenging profession, and medical students factor in many variables when choosing surgery as a career choice. The aim of this study is to review the available literature on the factors influencing Australian medical students' choice of surgery as their career. METHOD: A search of EMBASE and MEDLINE with the search terms 'medical students' AND 'surgery'; 'medical students' AND 'career pathways'; 'medical students' AND 'career choices' was conducted. Additionally, Google Scholar and the reference list of some articles were canvassed for suitable areas of study. RESULTS: Lifestyle factors were the main reason influencing medical student's career choices. A balance between work, family and lifestyle was found to be important, and a surgical career choice was not always compatible with this. In particular, female students placed more importance on family and lifestyle factors when opting for non-surgical careers. Positive exposure and/or experiences in a surgical environment, perceived prestige and perceived financial reward were associated with surgical career choice. CONCLUSIONS: There is a need to better understand the factors influencing surgical and non-surgical career choice among Australian medical students, and develop appropriate interventions to promote surgery as a career. This article does not discuss personality traits of people who go into surgery.

Prevalence and factors of burnout among Australian orthopaedic trainees: a cross-sectional study.

PURPOSE: To assess the prevalence and factors of burnout among Australian orthopaedic trainees. METHODS: 236 orthopaedic registrars of the Australian Orthopaedic Association were invited to participate in a 32-item survey by email. The questionnaire assessed potential factors associated with burnout, satisfaction with the choice of orthopaedics as a career and work-life balance, and subjective overall health, as well as 3 subscales of the Maslach Burnout Inventory - Human Services Survey for assessing burnout: emotional exhaustion, depersonalisation, and personal accomplishment. Participants with high levels of either emotional exhaustion or depersonalisation were defined as having burnout. Those with and without burnout were compared. RESULTS: 51 (22%) of the 236 trainees completed the questionnaire. Of whom, 88% were satisfied with their choice of orthopaedics as a career, whereas 27% were satisfied with their work-life balance. 27 (53%) respondents were considered burned out. Compared with those who did not burn out, those who burned out were less satisfied with their careers (p=0.004) and work-life balance (p=0.021). CONCLUSION: 53% of Australian orthopaedic trainees were burned out. Burnout trainees were more likely to be dissatisfied with their career choice and worklife balance. Active interventions to combat burnout and improve work-life balance are needed.
