Surgical outcome after treatment of thoracolumbar spinal stenosis in adults with achondroplasia.

PURPOSE: To describe the complications and the outcome of patients with achondroplasia undergoing thoracolumbar spinal surgery. METHODS: Retrospective analysis of prospectively collected data of all patients with achondroplasia undergoing surgery within the years 1992-2021 at the thoracic and/or lumbar spine. The outcome was measured by analyzing the surgical complications and revisions. The patient-rated outcome was assessed with the COMI score from 2005 onwards. RESULTS: A total of 15 patients were included in this study undergoing a total of 31 surgeries at 79 thoracolumbar levels. 12/31 surgeries had intraoperative complications consisting of 11 dural tears and one excessive intraoperative bleeding. 4/18 revision surgeries were conducted due to post-decompression hyperkyphosis. The COMI score decreased from 7.5 IQR 1.4 (range 7.1-9.8) preoperatively to 5.3 IQR 4.1 (2.5-7.5) after 2 years (p = 0.046). CONCLUSION: Patients with achondroplasia, the most common skeletal dysplasia condition with short-limb dwarfism, are burdened with a congenitally narrow spinal canal and are commonly in need of spinal surgery. However, surgery in these patients is often associated with complications, namely dural tears and post-decompression kyphosis. Despite these complications, patients benefit from surgical treatment at a follow-up of 2 years after surgery.

Musculoskeletal disorders and discomfort for female surgeons or surgeons with small hand size when using hand-held surgical instruments: a systematic review.

BACKGROUND: Work-related musculoskeletal disorders (WMSDs), also referred to as work-related musculoskeletal injuries (MSKIs), cause surgeons pain and discomfort. Implementing ergonomics in the operating room has helped reduce such symptoms. However, there are still many issues that surgeons face when dealing with medical instruments, especially among female surgeons or surgeons with smaller hands. METHODS: The Cochrane methodology for performing a systematic review was utilized to search five databases for pertinent literature based on the study question "Do female surgeons or surgeons with smaller hand size, who use surgical instruments have an increased risk of musculoskeletal disorders and discomfort compared to male or larger handed surgeons?". The literature search strategy was designed around the three conceptual domains of surgeons/surgery, smaller hand size, and instrumentation. We searched PubMed, Embase.com, CINAHL Plus with Full Text (EBSCOhost), Scopus, and Web of Science Core Collection. This exploration identified 2165 research publications, and after specific inclusion and exclusion criteria, 19 studies were included in the systematic review. Risk of bias analysis was conducted to assess the quality of the included studies. After conducting a heterogeneity test, a meta-analysis was not performed due to high heterogeneity. RESULTS: Using certain surgical instruments presents challenges in the form of MSKIs for female and smaller-handed surgeons. Studies showed that 77% of females and 73% of surgeons who wear < 6.5 glove size report musculoskeletal issues ranging from difficulty of use to pain. Difficulties using surgical instruments and reported injuries have a greater impact on surgical trainees which might deter interest in surgical fields for future proceduralists. Recommendations for improved ergonomic tool design are suggested by some of the included studies to help tackle the MSKIs that surgeons face when performing operations. CONCLUSIONS: The number of female surgeons has increased substantially in the last decade. Hence, there exists an urgent need to address the major challenges they encounter by focusing on this specific aspect of workplace safety and health to mitigate injury. Doing so will yield a productive environment while simultaneously protecting the health and safety of both surgeons and patients. SYSTEMATIC REVIEW REGISTRATION: The study protocol was registered on PROSPERO (ID: CRD42022283378).

Their clinical applications are expanding to encompass a variety of conditions, supported by a growing base of research efforts. Arthroscopy and its companion publications are committed to evidence-based research with a robust history of publications that enhance clinical decision-making and impact patient care. This curated collection of articles highlights the year's most compelling advancements in orthopaedic musculoskeletal biologics research.

NSAID use in orthopedic surgery: A review of current evidence and clinical practice guidelines.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a valuable class of medications for orthopedic surgeons and often play a pivotal role in pain control. However, there are many common stipulations resulting in avoidance of its use in the treatment of musculoskeletal disease. This review summarizes the mechanism of action of NSAIDs as well as provides an overview of commonly used NSAIDs and the differences between them. It provides a concise summary on the osseous effects of NSAIDs with regard to bone healing and heterotopic ossification. Most of all, it serves as a guide or reference for orthopedic providers when counseling patients on the risks and benefits of NSAID use, as it addresses the common stipulations encountered: "It irritates my stomach," "I have a history of bariatric surgery," "I'm already on a blood thinner," "I've had a heart attack," and "I've got kidney problems" and synthesizes both current research and society recommendations regarding safe use and avoidance of NSAIDs.

Ergonomics, musculoskeletal disorders, and surgeon gender in spine surgery: a survey of practicing spine surgeons.

OBJECTIVE: The objective of this study was to gain a greater understanding of the burden of musculoskeletal disorders (MSDs) in spine surgeons, their impact on practice, and risk factors contributing to MSDs, including surgical instrument design and surgical ergonomics. METHODS: An anonymous REDCap survey was distributed via email to the departments of several academic and private centers across the United States, as well as to the AANS/CNS Women in Neurosurgery Section email list. Chi-square tests and Wilcoxon rank-sum tests were used to compare responses by gender. Multivariable linear regression analysis was performed to identify predictors of discomfort in instrument utilization. RESULTS: Survey responses were received from 120 spine surgeons (29.1% response rate), of which 73 were included in the analysis. A very high number of respondents had experienced an MSD (70.4%), 38.2% had undergone treatment for at least one MSD, and 13.4% had lost time at work for at least one MSD. Women were more likely than men to have lost time at work due to an MSD (22.6% vs 5.6%, p = 0.04). Women were more likely than men to report difficulty in instrument grip, comfort, and use on a 20-point Likert scale (mean 10.7 vs 15.2 points, p < 0.0001). This effect persisted when adjusting for glove size and days per week spent operating (p = 0.002). Specifically, women were less likely to agree that the handles of surgical instruments were an appropriate grip (p < 0.0001), that they rarely experienced difficulty when using them (p < 0.0001), and that they rarely needed to use two hands with instruments meant to be used with one hand (p = 0.0002). CONCLUSIONS: The MSD burden in spine surgeons is substantial. While there was no evidence of gender differences in MSD rates and severity, female surgeons report significantly more discomfort with the use of surgical instruments. There is a need for more investigation of MSD risk factors in spine surgeons and mitigation strategies. Gender differences in comfort in instrument use should be further explored and addressed by spine surgeons and device manufacturers.

Mapping the Japanese orthopedic association national registry (JOANR) to the international classification of health interventions (ICHI).

BACKGROUND: The Japanese Orthopedic Association launched the Japanese Orthopedic Association National Registry (JOANR), Japan's first large-scale nationwide musculoskeletal disease registry, in 2020. The World Health Organization released the International Classification of Health Interventions (ICHI) Beta-3 version in the same year. This concurrence served as an impetus to examine the relationship between domestic and international classification for orthopedic interventions. Our objective was to evaluate the possibility of utilizing JOANR for international comparison and the potential usage of ICHI in the domestic medical fee reimbursement system. This study is a novel attempt at mapping a domestic orthopedic scheme to the ICHI. METHODS: We mapped 149 codes out of 581 orthopedic surgical codes, on JOANR's registration form, to the ICHI, and then classified the nature of JOANR codes' relationship, to both ICHI single stem codes and stem codes accompanied by other additional stem codes, extension codes, and International Classification of Diseases for Mortality and Morbidity Statistics (ICD) codes, into five categories: Equivalent (exact match), Narrower (compared to ICHI; can be smoothly incorporated into ICHI), Broader (compared to ICHI), Slipped (combination of both Narrower and Broader), and None (no appropriate code). Finally, debatable issues that arose during the mapping operation were noted. RESULTS: The domestic codes' relationship to ICHI single stem code by category were Equivalent: 27 (18.1%) and Narrower: 65 (43.6%), respectively. Further, the rate of Equivalent rose to 120 (80.5%) on adding other stem codes, extension codes, and ICD codes. Additionally, certain domestic titles, which were unsuitable for classification as they included diagnostic information, and arthroscopic surgeries without corresponding ICHI codes, were recoded. CONCLUSIONS: JOANR can be converted to an international comparison standard via ICHI to a certain extent, and ICHI accompanied by ICD codes has potential for deployment in the domestic medical fee reimbursement system.

"Imagine the future of our orthopaedics": The 38th Annual Research Meeting of the Japanese Orthopaedic Association.

The Japanese Orthopaedic Association (JOA) was founded in 1926, and the JOA has become one of the largest societies for musculoskeletal disorders in the world. The Annual Research Meeting of the JOA was established in 1973, and the meeting has been a forum in which Japanese orthopaedic surgeons, who perform basic research, can disseminate the results of their work. The contents of the meeting have improved with each meeting. This year, the meeting has reached its 38th year. The 38th Annual Research Meeting of the JOA will be held October 19-20, 2023 at the Tsukuba Science City. The thesis for the meeting is "IMAGINE THE FUTURE ", which is the slogan of the University of Tsukuba. At the meeting in Tsukuba, we look forward to having stimulating discussions with many orthopaedic surgeons regarding the future of orthopaedic science and clinical practice.

Patient preferences and decision-making when considering surgery for musculoskeletal disorders: A mixed methods systematic review.

INTRODUCTION: The burden of Musculoskeletal disorders (MSD) is large. Surgery is an important management option but the factors that shape patients' surgical decisions are not well understood. As prior reviews have explored only single data types or conditions, a mixed methods appraisal across the musculoskeletal spectrum was undertaken. METHODS: A mixed-methods systematic, convergent segregated approach was used, with PubMed, Cumulated Index to Nursing and Allied Health Literature (CINHAL), Embase and PsycINFO searched to identify studies of adult patients' decisions about whether to undergo surgery. A narrative synthesis was conducted, with identified themes integrated across quantitative, qualitative and mixed-methods studies. RESULTS: Forty-six studies were included (24 quantitative, 19 qualitative and three mixed methods), with four decision-making themes identified (symptoms, sociodemographic and health factors, information and perceptions). Decision-making involves a complex interaction of individual sociodemographic, health and symptom information, integrated with individual perceptions of candidacy and surgical expectations. While most studies investigated hip and knee surgery, across all included conditions, patients are more likely to favour surgery if symptoms and/or dysfunction are higher, and if perceptions of surgical candidacy and processes (outcomes, inconvenience, and risk) are favourable. Other factors including age, general health, race, financial context, professional and non-professional communication, and information sources also impact decision-making but exert a less consistent impact upon the propensity to prefer surgery. CONCLUSION: Patients are more likely to choose surgery for MSD when they have higher levels of symptoms or dysfunction and positive perceptions of surgical suitability and expectations. Other factors important to individuals, have a less consistent impact upon the propensity to prefer surgery. These findings have potential to aid the efficient referral of patients to orthopaedics. More research is needed to validate these findings across the spectrum of MSD.

International orthopaedic trials.

Musculoskeletal diseases are having a growing impact worldwide. It is therefore crucial to have an evidence base to most effectively and efficiently implement future health services across different healthcare systems. International trials are an opportunity to address these challenges and have many potential benefits. They are, however, complex to set up and deliver, which may impact on the efficient and timely delivery of a project. There are a number of models of how international trials are currently being delivered across a range of orthopaedic patient populations, which are discussed here. The examples given highlight that the key to overcoming these challenges is the development of trusted and equal partnerships with collaborators in each country. International trials have the potential to address a global burden of disease, and in turn optimize the benefit to patients in the collaborating countries and those with similar health services and care systems.

A Specialist-Led Care Model: Aligning the Patient and Specialist for the Greatest Impact.

In the previous paper, discussing "Risk and the Future of Musculoskeletal Care," we reviewed the basic concepts of the risk corridor, implications on health care overall if we maintain a fee-for-service model, and the need for musculoskeletal specialists to begin taking on/managing risk to reinforce our presence in a "value-based care" system. This paper discusses the successes and failures of recent value-based care models and provides the framework for the paradigm of a specialist-led care model. We posit that orthopedic surgeons are the most knowledgeable physicians to manage musculoskeletal conditions, create new and innovative models, and lead value-based care to the next level.

Which treatment provides the best neurological outcomes in acute spinal cord injury?

Initial treatment of traumatic spinal cord injury remains as controversial in 2023 as it was in the early 19th century, when Sir Astley Cooper and Sir Charles Bell debated the merits or otherwise of surgery to relieve cord compression. There has been a lack of high-class evidence for early surgery, despite which expeditious intervention has become the surgical norm. This evidence deficit has been progressively addressed in the last decade and more modern statistical methods have been used to clarify some of the issues, which is demonstrated by the results of the SCI-POEM trial. However, there has never been a properly conducted trial of surgery versus active conservative care. As a result, it is still not known whether early surgery or active physiological management of the unstable injured spinal cord offers the better chance for recovery. Surgeons who care for patients with traumatic spinal cord injuries in the acute setting should be aware of the arguments on all sides of the debate, a summary of which this annotation presents.

The Treatment of Complex Extremity Wounds Using External Tissue Expansion: A Case Series.

SUMMARY: The goal of wound reconstruction is the approximation of soft tissue and re-establishment of an acceptable appearance with minimal risk of complications. For large wound closure in the extremities, skin graft and flap reconstruction are common treatments but are associated with a variety of complications. Comparatively, tissue expansion can provide the opportunity to reconstruct large wounds with native, durable, and sensate tissue without significant donor site morbidity. External tissue expansion is less invasive and avoids complications associated with internal expansion. The authors treated 11 patients with varying extremity wound types and sizes with an external tissue expansion device. Patient age ranged from 18 to 68 years with an average age of 43.7 years (SD, ± 13.1 years). Average wound surface area was approximately 235 cm 2 (SD, ± 135.3 cm 2 ). Devices were affixed and left for 7 to 11 days before closure of the wounds. Outcomes were assessed at 2 to 36 weeks postoperative follow-up. All wounds were fully closed after treatment without need for secondary reconstructive procedures. No patient experienced major complications. All patients demonstrated intact sensation within the area of reconstruction equivalent to surrounding tissues. External tissue expansion, an excellent treatment option in extremity reconstruction, is efficacious and associated with lower complication rates compared with internal tissue expansion, skin grafts, and flap reconstruction. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

The Obeid-coronal malalignment classification is reliable and helps guiding decision-making and surgical management of adult spinal deformities: letter to the editor of BMC Musculoskeletal Disorders.

A recently published article by Zhang et al. in BMC Musculoskeletal Disorders reported that the classification of coronal deformity based on preoperative global coronal malalignment for adult spinal deformity is questionable. The aim of the paper was to specifically discredit the Obeid-Coronal Malalignment (O-CM) classification. In this correspondence, we thought it judicious to clarify misunderstood concepts by the authors. We highlight several limitations of their study, and explain the deep interest of the classification from our perspective in order to avoid misleading the readers. Overarching, we aim to help the colleagues through a constructive rather than destructive approach to better understand the foundations of a coronal malalignment classification.

Prevalence, Prevention, and Treatment of Work-Related Musculoskeletal Disorders Among Microsurgeons.

BACKGROUND: While work related musculoskeletal disorders have been well recognized among all surgeons, and microsurgeons in particular; their prevention and treatment are presently unknown. Our study aims to define the impact of musculoskeletal ailments on microsurgeons and investigate trends in microsurgeon musculoskeletal injury treatment. METHODS: An electronic survey was sent to all members of the American Society of Reconstructive Microsurgery. The survey solicited surgeon demographics, microsurgical volume, equipment usage, history of musculoskeletal injury, impact of injury, and interventions / treatment modalities used to address / prevent these issues. RESULTS: Of the 883 microsurgeons surveyed, 203 responded (23% response rate). The average age was 45 years (IQR 39-52 years). Most microsurgeons were male (80.8%). Musculoskeletal injury or symptoms related to microsurgery were reported by 137 respondents (67.0%). Fifty surgeons (37.9%) reported that their musculoskeletal injury had adversely affected their practice. Formal medical intervention was sought by 53 respondents (26.1%), with 17 surgeons (8.4%) undergoing surgical intervention. Self-treated was used by 127 microsurgeons (62.6%) for musculoskeletal ailments. Preventative treatments such as strength training, stretching, yoga, massages, and diet were the most beneficial, each with utilization scores of 4 out of 5. CONCLUSION: A majority of microsurgeons experience musculoskeletal injury, and some even require surgery to treat their musculoskeletal pathology. Prophylactic practices such as strength training, stretching, yoga, massages, and diet maintenance, are the superior treatment for musculoskeletal injury. Microsurgeons should incorporate training routines in their lives as injury prophylaxis to improve their career longevity and patient care.

Percutaneous biopsy of musculoskeletal tumors and the potential for needle tract seeding: technical considerations, current controversies, and outcomes.

Multidisciplinary communication and planning between the musculoskeletal radiologist and orthopedic oncologist are essential for proper biopsy planning when a primary musculoskeletal malignancy is suspected. Image-guided percutaneous biopsy allows for real-time visualization of the biopsy needle and surrounding structures, combining high diagnostic accuracy with safety and cost-effectiveness. However, determining a surgically optimal biopsy trajectory for a mass can be technically challenging due to critical surrounding anatomy or challenging needle approach angles. Inappropriately placed biopsies can have serious repercussions on patient function and oncological survival. The potential for needle tract seeding and local recurrence after biopsy of sarcoma has been central to the debate regarding the need for excision of the biopsy tract. This multidisciplinary review highlights current controversies in the field, including the issue of core needle biopsy tracts and their excision, technical considerations and advances in image-guidance in the setting of challenging biopsies, advances in histopathological diagnostics with implications for targeted therapy in sarcoma, as well as surgical and oncological outcomes after needle tract biopsy.

Risk factors that hinder locomotive syndrome improvement following surgery for musculoskeletal diseases in older patients: A multicentre prospective study.

OBJECTIVES: This study aimed to evaluate preoperative and post-operative locomotive syndrome (LS) in older adults undergoing surgical treatment for musculoskeletal diseases of the lumbar spine and lower extremities and identify risk factors that impede LS improvement after surgery. METHODS: The baseline evaluation included 471 patients 65 years or older [276 in the pre-old-age (65-74 years) group; 195 in the old-age (75 years or older) group] and examined the preoperative and post-operative LS data. The second evaluation performed to identify risk factors, including anthropometric measurements, comorbidity, and frailty, that hinder LS improvement after surgery included 378 patients with preoperative LS Stage 3. RESULTS: Preoperatively, 80% of the patients had LS Stage 3; this rate decreased to 40% post-operatively. Half of the patients exhibited post-operative LS improvement. The LS improvement rate was higher in the pre-old-age group than in the old-age group. According to the multiple logistic regression analysis, old age, high body mass index, weak hand grip strength, and high 5-factor modified frailty index score were significant risk factors that hinder LS improvement after surgery. CONCLUSIONS: Ageing, obesity, weak muscle strength, and frailty can hinder LS improvement in older patients who undergo surgery.
