Advancing robot-guided techniques in lumbar spine surgery: a systematic review and meta-analysis.

BACKGROUND: Lumbar spine surgery is a crucial intervention for addressing spinal injuries or conditions affecting the spine, often involving lumbar fusion through pedicle screw (PS) insertion. The precision of PS placement is pivotal in orthopedic surgery. This systematic review compares the accuracy of robot-guided (RG) surgery with free-hand fluoroscopy-guided (FFG), free-hand without fluoroscopy-guided (FHG), and computed tomography image-guided (CTG) techniques for PS insertion. METHODS: A systematic search of various databases from 1 January 2013 to 30 December 2023 was conducted following PRISMA guidelines. Primary outcomes, including PS insertion accuracy and breach rate, were analyzed using a random-effects model. Risk of bias was assessed using the Newcastle-Ottawa Scale. RESULTS: The overall accuracy of PS insertion using RG, based on 37 studies involving 3,837 patients and 22,117 PS, is 97.9%, with a breach rate of 0.021. RG demonstrated superior accuracy compared to FHG and CTG, with breach rates of 3.4 and 0.015 respectively for RG versus FHG, and 3.8 and 0.026 for RG versus CTG. Additionally, RG was associated with reduced mean estimated blood loss compared to CTG, indicating improved safety. CONCLUSIONS: The RG is associated with enhanced accuracy of PS insertion and reduced breach rates over other methods. However, additional randomized controlled trials comparing these modalities are needed for further validation. PROSPERO REGISTRATION: CRD42023483997.

Effect analysis of applying high-quality service model to surgical nursing.

BACKGROUND: Surgical care of the hand plays a crucial role in the medical field, as problems with the hand can profoundly affect a patient's quality of life and function. In order to meet the needs of patients, improve patient satisfaction and improve treatment outcomes, high-quality service models have been introduced in the field of nursing. AIM: To explore the effect analysis of applying high-quality service model to surgical nursing. METHODS: We conducted a retrospective study of patients who underwent hand surgery at our hospital between 2019 and 2022, using a quality service model that included improved patient education, pain management, care team collaboration, and effective communication. Another group of patients received traditional care as a control group. We compared postoperative recovery, satisfaction, complication rate, and length of hospital stay between the two groups. Inferential statistics were used to compare the difference between the two groups by independent sample t test, Chi-square test and other methods to evaluate the effect of intervention measures. RESULTS: Postoperative recovery time decreased from 17.8 ± 2.3 d to 14.5 ± 2.1 d, pain score decreased from 4.7 ± 1.9 to 3.2 ± 1.4, and hand function score increased from 78.4 ± 7.1 to 88.5 ± 6.2. In terms of patient satisfaction, the quality service model group scored 87.3 ± 5.6 points, which was significantly higher than that of the traditional care group (74.6 ± 6.3 points). At the same time, patients' understanding of medical information also improved from 6.9 ± 1.4 to 8.6 ± 1.2. In terms of postoperative complications, the application of the quality service model reduced the incidence of postoperative complications from 26% to 10%, the incidence of infection from 12% to 5%, and the incidence of bleeding from 10% to 3%. The reduction in these data indicates that the quality service model plays a positive role in reducing the risk of complications. In addition, the average hospital stay of patients in the quality service model group was shortened from 6.8 ± 1.5 d to 5.2 ± 1.3 d, and the hospitalization cost was also reduced from 2800 ± 600 yuan to 2500 ± 500 yuan. CONCLUSION: Applying a quality service model to hand surgery care can significantly improve patient clinical outcomes, including faster recovery, less pain, greater satisfaction, and reduced complication rates.

Extraskeletal Ewing Sarcoma Disguised as a Vascular Malformation.

Extraskeletal Ewing sarcoma (EES) is a rare entity, accounting for only 3% of lesions encountered in upper extremity. We present two paediatric patients, who were initially diagnosed with a vascular malformation based on clinical assessment and imaging. Final histopathology revealed Ewing sarcoma of soft tissue origin, confirmed by immunohistochemical analysis. Hand surgeons, who are routinely approached for a myriad of hand pathologies, should be wary and consider EES as a differential when treating such lesions. A multidisciplinary approach with an appropriate treatment algorithm can help in a speedy diagnosis, improving the long-term prognosis of the disease. Level of Evidence: Level V (Therapeutic).

Sports and Recreation-Related Wrist Fractures: An Epidemiological Study.

Background Wrist fractures have increased over the past several decades. The objective of this study was to identify all-cause and sports-related incidence rates of wrist fractures presenting to emergency departments (EDs) in the United States (U.S.) from 2013 to 2022. A secondary aim of the study was to identify if wrist fractures significantly decreased during 2020. Methodology The National Electronic Injury Surveillance System database was queried to identify the number of wrist fractures presenting to U.S. EDs from 2013 to 2022. Incidence rates in 100,000 person-years were calculated by sport, age, sex, and year. Results From 2013 to 2022, there were 2,027,131 wrist fractures evaluated at U.S. EDs. Injuries peaked in the 10-14-year-old age group, followed by the 5-9 and 85+-year-old age groups. In total, 1,096,598 were sustained during sports and recreation. Cycling, playgrounds, and skateboarding were the leading sports and recreation-related activities. Sports-related wrist fractures followed a unimodal distribution peaking in the 10-14-year-old age group. Females sustained 52% of wrist fractures overall but only 39% of sports-related wrist fractures. All-terrain vehicle and skateboarding-related wrist fractures significantly increased over the study period. Playground and soccer-related wrist fractures significantly decreased in 2020. Conclusions All-cause wrist fractures presenting to U.S. EDs significantly increased from 2013 to 2022 though sports-related wrist fractures did not. Pediatric males and elderly females are most at risk for wrist fractures overall while sports-related wrist fractures predominate in the pediatric population. Youth sports and recreation officials should be aware of the risks to mitigate the incidence of sports-related wrist fractures.

Intramedullary Threaded Nail Fixation of Distal Ulnar Fractures: The Surgical Technique and Case Series.

BACKGROUND:  To describe the surgical technique of non-compressive intramedullary threaded nail (IMTN) fixation of distal ulnar neck fractures and present the clinical and radiographic outcomes of four patients treated with this novel technique. METHODS: At a single Level 1 Trauma Center, a retrospective review was conducted for patients with distal ulnar neck fractures treated with retrograde IMTN between 2022 and 2024. Exclusion criteria included inadequate follow-up. A single surgeon performed all procedures using percutaneous retrograde IMTN fixation through the central disc of the triangular fibrocartilage complex (TFCC). Patients initiated a range of motion (ROM) protocol two weeks post-operatively. Post-operative radiographic images were used to calculate the ratio of IMTN diameter to the distal ulnar medullary isthmus diameter proximal to the fracture site. Radiographic changes in displacement, angulation, and ulnar variance were calculated between the first and last follow-up radiographs. Functional outcomes including grip strength and ROM were collected. RESULTS: Four patients with distal ulnar neck fractures were treated with retrograde IMTN between 2022 and 2024. They were followed for a minimum of three months post-operatively. All were female with an average age of 65 years. All distal ulna fractures were associated with operatively treated intraarticular distal radius fractures. All patients were treated with 75 mm length and 4.5 mm diameter IMTNs. IMTN-to-Isthmus ratio was greater than 60% in all cases. Average radiographic displacement and angulation were unchanged at the final follow-up. The average ulnar variance increased by 1.2 mm. At the final follow-up, there were no post-operative complications. No cases demonstrated ulnar-sided wrist pain, nonunion, or required revision surgery. CONCLUSIONS: Retrograde IMTN fixation is a novel surgical technique for the treatment of distal ulnar neck fractures. We found limited but promising post-operative radiographic and functional outcomes in our patients without reported ulnar-sided wrist pain, nonunion, or need for hardware removal.

Unusual Anastomosis between Branches of the Ulnar Nerve (Kaplan Type Anastomotic Variant) - Case Report.

The Kaplan anastomosis is a rare communication originally described between the superficial and dorsal branches of the ulnar nerve, distal to the ulnar tunnel, and in strict relation with the pisiform bone. It reveals, by its particular location, a formation of high clinical-surgical expressiveness. In this paper, we describe a Kaplan-type communication from a left upper limb with an unusual loop conformation between branches of the ulnar nerve in the pisiform bone.

Polylactic acid bioabsorbable implants of the hand: A review.

In the treatment of hand fractures, metal implants are often used to allow early range of motion and a stable fixation. Although they provide adequate bone union, metal implants have been known to cause joint stiffness, painful or prominent hardware, and adhesions, often leading to another surgery for hardware removal. Bioabsorbable implants have been shown to offer comparable results for fracture fixation in the hand while removing the complications seen with retained hardware. In this article, we review biomechanical and clinical studies focused on bioabsorbable implants made of polylactic acid used for orthopedic hand injuries in order to promote their continued use and future research.

Shared Decision Making in Hand Surgery.

Shared decision-making (SDM) is a collaborative effort between a physician and a patient to make an informed clinical decision, as defined by each patient's preferences and values. Shared decision-making is particularly used in areas of clinical equipoise or preference-sensitive conditions, which are common in hand surgery. Although there is increased interest in SDM across health care, hand surgeons receive little formal training on SDM. In this review, we explore existing barriers to SDM in hand surgery and provide a framework for participating in SDM discussions.

The Effect of Anticoagulant and Antiplatelet Medications on Wide-Awake Hand Surgery: An Analysis of 2,162 Cases.

PURPOSE: The purpose of the study was to determine if perioperative prescription anticoagulant (AC) or antiplatelet (AP) medication use increases the rate of revision surgeries or complications following wide-awake hand surgery performed under local anesthesia. METHODS: All patients who underwent outpatient wide-awake hand surgery under local anesthesia without a tourniquet by two fellowship-trained orthopedic hand surgeons at a single academic practice over a 3-year period were included. Prescription history was reviewed to determine if any prescriptions were filled for an AC/AP drug within 90 days of surgery. All cases requiring revision were identified. Office notes were reviewed to determine postoperative complications and/or postoperative antibiotics prescribed for infection concerns. The number of revisions, complications, and postoperative antibiotic prescriptions were compared between patients who did, and did not, use perioperative AC/AP drugs. RESULTS: A total of 2,162 wide-awake local anesthesia surgeries were included, and there were 128 cases (5.9%) with perioperative AC/AP use. Of the 2,162 cases, 19 cases required revision surgery (18 without AC/AP use and one with AC/AP use). Postoperative wound complications occurred in 42 patients (38 without AC/AP use and four with AC/AP use). Of the wound complications, four were related to postoperative bleeding, one case of incisional bleeding, and three cases of incisional hematomas (three without AC/AP use and one with AC/AP use). None of these patients required additional intervention; their incisional bleeding or hematoma was resolved by their subsequent office visit. Sixty-five patients received postoperative antibiotics for infection concerns (59 without AC/AP use and six with AC/AP use). CONCLUSIONS: Prescription AC/AP medication use in the perioperative period for wide-awake hand surgery performed under local anesthesia was not associated with an increased risk for revision surgery or postoperative wound complications. This study demonstrates the safety of continuing patients' prescribed AC/AP medications during wide-awake hand surgery. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognosis IV.

Algorithm-Guided Treatment of Ulna Impaction Syndrome: A 10-Year Follow-Up Study of Ulna Shortening Osteotomy and Wafer Procedure.

Background: Ulnar impaction syndrome (UIS) is a common degenerative wrist condition which results from positive ulnar variance, leading to an overload on the ulnar carpus. Ulnar shortening osteotomy (USO) and the arthroscopic wafer procedure (AWP) are established therapies for UIS if conservative management fails. This study assessed an algorithm-guided treatment of UIS over a period of 10 years. Methods: This prospective observational study compared the outcome of 54 patients who underwent either USO or AWP for UIS based on a predefined treatment algorithm. The mean follow-up period was 10 years. Primary outcome parameters were the visual analogue scale (VAS) for pain and the Disabilities of the Arm, Shoulder, and Hand questionnaire (DASH), whereas secondary outcome parameters were grip and pinch strength and range of motion. Results: The median preoperative ulnar variance was 2.6 mm in the USO group and 2.0 mm in the AWP group. The postoperative average ulnar variance was 0 mm in both groups. The preoperative pain at rest was 3.4 in the USO group and 2.3 in the AWP group. One year after surgery, there was a significant reduction to VAS 0.7 and 0.2, respectively. These results persisted to the 10-year follow-up (VAS 0.9 and 0.2). The pain in motion also decreased significantly in the first year (from 6.8 and 6.7 to 2.2 and 2.1), as well as after 10 years (2.4 and 1.0). The preoperative DASH score averaged 31.3 in the USO group and 35.8 in the AWP group. At the 10-year follow-up, the DASH of both groups decreased significantly to 4.35 in the AWP group compared to 12.7 in the USO group. Conclusions: Our data show that, when using our algorithm, both USO and AWP, two common operative treatment options of UIS, reliably reduce pain and significantly reduce the DASH score over at least a period of ten years. The results after 10 years differ from short-term results in so far as after one year, the USO group showed to some degree similar outcome parameters compared to AWP, whereas at the 10-year follow-up, AWP reached slightly better primary outcome parameters. The algorithm presented, thus, produced excellent short- and long-term outcomes. Our findings and the applied algorithm can assist in decision-making and patient education.

Establishing the psychological impact of congenital upper limb differences on parents and families.

The aim of this prospective study was to report the psychological experiences of parents caring for children with a congenital upper limb difference and to compare these to population norms. Contributing factors were explored, including access to support and coping strategies. Finally, parents with a congenital upper limb difference themselves were compared to those without. Data recorded included demographics, a validated wellbeing and family impact measure, a unique measure of emotions experienced and exploratory questions. Wellbeing and family impact scores were significantly lower than populations norms. Mothers experienced significantly more negative emotions than fathers. There was no significant different between parents with and without a congenital upper limb difference. Of the parents, 68% felt there should be improved access to psychological support. This demonstrates that parents of children with congenital upper limb differences have unique psychological experiences and needs. They may benefit from specialist psychological support and further research is needed.Level of evidence: III.

Under 2$ hand anesthesia? Our first 800 cases with Wide-Awake Local Anesthesia No Tourniquet (WALANT) in hand surgery.

INTRODUCTION: The Wide-Awake-Local-Anesthesia-No-Tourniquet (WALANT) technique is being used progressively more and more in hand surgery as it avoids tourniquet-related complications and saves money. MATERIALS AND METHODS: In the present study, we analyzed our cases of carpal tunnel syndrome or trigger finger operated upon with this technique from January 1, 2018 to December 31, 2022. RESULTS: We obtained 822 cases (426 carpal tunnel syndrome, 396 trigger finger) with an overall anesthesiologic efficacy (no need of additional anesthetic) of 97.8%. Patients were satisfied or very satisfied with the anesthetic choice in 99.8% of cases. CONCLUSIONS: We believe WALANT to be a safe and effective technique that every hand surgeon should have in his/her repertoire.

Orthopedic Surgery Residents: How Much Do They Know About Occupational Therapy?

Background Orthopedic hand surgeons rely on occupational therapy (OT) as a crucial part of rehabilitation following injury or surgery. Therefore, orthopedic surgeons should understand the full range of OT services. There is limited prior research on orthopedic residents' understanding of OT in the United States. The main goal of this study is to examine how well orthopedic surgery residents grasp and perceive the role of OT, particularly in hand surgery, as integrated into their educational curriculum. Methods The study included all orthopedic surgery residents from a single institution (Columbia University, New York) during 2022-2023. We obtained permission from the Institutional Review Board, Department Chair, and Program Director to recruit participants. Eligible residents who agreed to participate completed questionnaires regarding their understanding of the role of OT in orthopedic surgery. Results Thirty subjects met the inclusion criteria. The total response rate from the residents was 14/30 (47%). The residents reported a mediocre level of familiarity with OT while also rating 4.5/5 the importance of OT in hand surgery without significant difference between postgraduate year groups. 11/14 residents reported no formal training concerning the role of OT in hand surgery. 12/14 residents reported that it would be helpful to spend time with an occupational therapist. Conclusions This study revealed the lack of confidence residents expressed regarding occupational therapists' roles. All residents recognized the importance of OT in hand surgery and expressed interest in shadowing occupational therapists. Residents of all levels acknowledge the crucial partnership between orthopedists and occupational therapists but lack formal education about the therapist's scope and role.

Association of Timing With Postoperative Complications in the Management of Open Distal Radius Fractures.

BACKGROUND: This study investigates whether open distal radius fractures (ODRFs) treated after 24 hours from time of injury have an increased risk of infection or overall complication profile compared with those treated within 24 hours. METHODS: Retrospective review was performed of all patients treated for ODRF over a 6-year period at a single large academic institution. Postoperative complications included surgical site infections, need for revision irrigation and debridement, delayed soft tissue healing, loss of reduction, nonunion, and malunion. RESULTS: One-hundred twenty patients were treated for ODRF. Mean (SD) age at time of injury was 59.92 (17.68) years. Twenty patients (16.7%) had postoperative complications. Regarding mechanism of injury, 78 (65.0%) had a low-energy and 42 (35.0%) had a high-energy injury. Age and fracture grade were not significant factors. Mean (SD) open wound size was 1.18 (1.57) cm. Mean (SD) time from injury presentation to the emergency department (ED) and first dose of intravenous antibiotics was 3.07 (4.05) hours and mean (SD) time from presentation to the ED and operative treatment was 11.90 (6.59) hours, which did not show a significant association with postoperative complications. Twenty-four patients (20.0%) were treated greater than 24 hours after presentation to the ED, which was not significantly distinct from those treated within 24 hours. CONCLUSION: Patients with ODRFs treated after 24 hours were not associated with a greater risk of postoperative complications. Factors including age, energy and mechanism of injury, and fracture grade did not alter outcome in any statistically significant manner. LEVEL OF EVIDENCE: Level IV.

Hand Surgery in Indonesia.

The history of hand surgery in Indonesia began with the growing interest in performing a complicated hand surgery. Since the 1970s, hand surgery in Indonesia has made headway, especially when it comes to science and education. The development of hand surgery in Indonesia is not limited to a microsurgery area, but also covers more modern techniques, including reconstruction, minimal invasive surgery, arthroscopy, and various kinds of innovations and developments to overcome the high cost of health, especially medical devices in Indonesia. Voluntary visitations to help or take surgery procedures in many remote areas in Indonesia, such as Papua and Nusa Tenggara, have also contributed to the development of hand surgery. Currently, hand surgery in Indonesia is improving and growing significantly.

Evaluating patient satisfaction with WALANT for hand surgery: a comprehensive questionnaire-based study.

INTRODUCTION: There has been an increase in the popularity of the wide-awake local anesthesia no-tourniquet (WALANT) procedure for various upper limb surgeries. The present study aims to conduct a comprehensive analysis of the satisfaction levels of 106 patients, considering factors such as age, gender, comorbidities, and the specific procedures they underwent. METHOD: The present study was a retrospective cohort study conducted to analyze the overall satisfaction of a cohort of 106 patients who underwent various surgical procedures of the hand between 2018 and 2023. The satisfaction was assessed with a questionnaire comprising 13 questions/statements adjusted to a standard Swiss grading system (from 1 = I strongly agree to 6 = I strongly disagree). RESULTS: Overall satisfaction with WALANT was high, with most patients expressing positive experiences. Patients with hypertension reported similar satisfaction levels compared to those without, while diabetic patients experienced significantly higher anxiety levels during the procedure (p > 0.05). CONCLUSION: WALANT exhibits versatility as an anesthesia choice, demonstrating efficacy in both routine and complex hand surgeries. Our survey-based study reveals a high satisfaction level across diverse procedures. When assessing the correlation between WALANT satisfaction and patient comorbidities, hypertension displayed no significant impact, while diabetic patients reported heightened anxiety. Importantly, patient satisfaction remained consistently high even within the subgroup with comorbidities. Our results underscore WALANT's reliability in upper limb surgery, showcasing its usefulness and positive outcomes across a broad range of patients and surgical procedures.

Hand Surgeon Posture: An Evaluation and Factors That Affect It.

Objective: Approximately 68% of orthopaedic surgeons report occupational related musculoskeletal pain, with back pain being the most common. Poor posture while operating has been proven to contribute to these high rates of musculoskeletal pain. There is little research regarding intraoperative surgeon posture within the field of hand and upper extremity surgery. This prospective study aims to investigate and analyze hand surgeon posture in the operating room. Methods: Posture of three hand surgeons was recorded using the UPRIGHT GO posture tracking device while performing a prospective series of 223 hand and upper extremity surgeries. This device reports posture in terms of overall percentage of time spent slouched versus upright. For this cohort of 223 cases, data were collected including surgical procedure, whether the surgery was performed in a seated or standing position, whether or not loupes were worn during the procedure, and if the surgeon was the primary or assistant surgeon. These data were then analyzed to look for any contributing factors to poor posture. Results: The three hand surgeons in this study spent an average of 40.3% of their time slouched while operating. The average percentage of time slouched was significantly greater with the use of loupes versus no loupes. Additionally, mean time slouching was slightly increased when the surgeon was seated and also when the surgeon was acting as the assistant surgeon. Conclusion: The three orthopaedic hand surgeons in our study spent a significant portion of their operative time slouched. The main variable associated with a significant risk of poor surgical posture was wearing loupes. Slight increases in slouching were seen with operating while seated and as the assistant surgeon. Surgeon awareness of these variables, as well as techniques to improve surgeon posture, should be developed in order to help contribute to better surgeon posture within the field of hand surgery.

Practice Trends in Plastic Hand Surgery: An Evaluation of Cases in the TOPS Database.

Background: Previous studies have sought to outline the clinical practice of hand surgeons with plastic surgery training backgrounds. Still, minimal data exist characterizing the scope of hand surgery among plastic surgeons, regardless of the subspecialty fellowship training. Methods: All hand procedures logged in the Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database from 2002 to 2016 were identified by the Common Procedural Technology (CPT) code and/or "upper extremity" anatomic classification. Trends in the total number and types of procedures, facility type, admission type, modes and providers of anesthesia, and patient demographics were reviewed. Results: A total of 182,137 hand procedures performed on 82,811 patients during the 15-year period were reviewed. Sixty-eight percent of procedures involved soft tissue only, and 22.7% involved only bone and/or joint. The most common procedure categories included the following: wound closure/coverage (15.8%), debridement/drainage (15.3%), nerve (13.2%), tendon (12.9%), and fracture/dislocation (12.9%). Ambulatory and office-based procedures increased over time, along with the use of local anesthetic, as well as a transition from the procedural surgeon providing anesthesia to the use of anesthesiologists and nurse anesthetists. In addition, hand procedures have remained a considerable proportion of all logged procedures but have seen a steady decline since 2014. Conclusion: Plastic surgeons play an important role in the field of hand surgery, performing a wide variety of procedure types, which has remained stable over time. The trends in facility type and anesthesia characteristics have, however, varied.

Orthopaedic Hand Surgical Simulation Training: A Review.

In recent years, new orthopaedic surgical simulation and virtual reality (VR) training models have emerged to provide unlimited education medium to an unlimited number of trainees with no time limit, especially in response to trainee work-hour restrictions. Surgical simulators range from simple wooden boxes to animal and cadaver models to three-dimensional-printed and VR simulators. The coronavirus disease 2019 pandemic further highlighted the need for at-home learning tools for orthopaedic surgical trainees. Advancement in simulating shoulder and knee arthroscopies using VR simulators surpasses the other fields in orthopaedic surgery. Despite the high degree of precision needed to operate at a microscopic level involving vessels, nerves, and the small bones of the hand, the simulation tools have limited advancement in the field of orthopaedic hand surgery. This narrative review summarizes the status of surgical simulation and training techniques available to orthopaedic hand surgical trainees, factors affecting their application, and areas in hand surgery that still lag behind their surgical subspecialty counterparts.
