Emergency Department Visits After Total Joint Arthroplasty in a Closed Urban Setting: A Report of 1,000 Consecutive Cases.

Rates of emergency department (ED) visits and readmissions after total joint arthroplasty (TJA) have been cited as indicators of TJA quality. Understanding the incidence and nature of these events is critical for prevention. The purpose of this study was to analyze readmission rates 30 and 90 days after TJA at a safety-net hospital in an urban setting and to compare this readmission rate with that for non-safety-net hospitals found in the current literature. In addition, we aimed to quantify the readmissions in our safety-net hospital that led to future complications. This would help us identify if there is a high incidence of preventable readmission rates in this unique socioeconomic environment. Using our institutional electronic medical record system, we retrospectively studied 1000 consecutive TJA encounters between 2014 and 2019 to determine the rates of treat-and-release ED visits within 30 and 90 days after surgery. The ED charts were reviewed, and patients who returned to the operating room (OR) for a TJA complication within 1 year of surgery were identified. We compared the OR return rates of people who had ED visits with those in the control group. A total of 110 (11%) and 191 (19.1%) patients visited the ED within 30 and 90 days of surgery, respectively. Fisher exact test confirmed that having an ED visit within 90 days of TJA because of lower extremity pain and/or swelling or a social issue was associated with returning to the OR within a year of TJA. Having an ED visit within 30 or 90 days of total hip replacement was associated with returning to the OR for total hip replacement complications. ED visits after TJA at an urban safety-net hospital were markedly higher than those reported in the literature for nonurban safety-net hospitals. In addition, postoperative ED visits for specific diagnoses may predict complications. This indication may have implications for a risk adjustment in programs such as bundled payments. Our results also indicate overutilization of the ED by avoidable ED visits. This represents a call for alternatives to the ED for patients after TJA in environments served by safety-net hospitals.

Efficacy of Different Doses of Intra-Articular Tranexamic Acid for Reducing Blood Loss and Lower Limb Swelling After Total Knee Arthroplasty: A Prospective, Randomized, Controlled Trial.

Both blood loss and lower extremity swelling after total knee arthroplasty (TKA) can affect a patient's postoperative recovery. The aim of this trial was to investigate whether different doses of intra-articular tranexamic acid (TXA) can reduce blood loss and postoperative lower limb swelling. In a prospective, randomized-controlled trial, a total of 225 patients were randomly assigned to three groups from September 2020 through January 2021: intra-articular injections of 3 g, 1 g of TXA, or placebo (saline solution). The primary outcome indicators were perioperative blood loss and decreased hemoglobin levels. The secondary outcome indicators were lower extremity swelling, functional recovery indicators (hospital for special surgery [HSS] scores, range of motion), visual analog scale [VAS] scores, and transfusion rates and safety outcomes, including thromboembolic events, incidence of wound-related complications, and length of hospital stay. One-way analysis of variance (ANOVA), post hoc Bonferroni correction, Pearson chi-square test and Fisher exact test were used for statistical analysis. Postoperative blood loss was lower in the 1 and 3 g TXA groups (754.00 ± 409.67 mL and 568.70 ± 408.27 mL, respectively) than in the placebo group (977.32 ± 418.69 mL) (p < 0.001). The maximum postoperative decrease in hemoglobin was lower in the 1 and 3 g TXA groups (2.4 ± 0.9 and 1.8 ± 0.9 g/dL, respectively) than in the placebo group (3.1 ± 1.2 g/dL) (p < 0.001). On postoperative Days 1, 2, and 3, the TXA group presented significantly reduced thigh, suprapatellar, and calf swelling and significantly reduced pain scores during exercise. Compared with that in the low-dose group, perioperative blood loss was further reduced in the high-dose TXA group (p = 0.006). However, while patients in the TXA group had improved pain scores, Hospital for Special Surgery scores, and joint range of motion at postoperative rest, these differences were not statistically significant. There were no significant differences in thromboembolic events or complication rates among the three groups. Topical TXA in total knee arthroplasty was effective in reducing postoperative blood loss by 24%-43% and in reducing postoperative lower extremity swelling and pain during exercise. Higher doses (3 g) of TXA further controlled perioperative blood loss without affecting postoperative lower extremity swelling, and there was no increase in the incidence of related complications during follow-up. This study was a single-center, prospective, randomized controlled trial (RCT). The trial was approved by the Clinical Trials and Biomedical Ethics Committee at our institution (number: 2018.676), all participants provided written informed consent, and the trial was prospectively registered in the Chinese Clinical Trial Registry (ChiCTR2000035271).

Pain in Children and Adolescents with Cerebral Palsy: A Cross-sectional Survey Study.

This study aims to investigate the prevalence, intensity, and location of pain in children and adolescents with cerebral palsy (CP) and analyze pain-related symptoms and participation restrictions. Children and adolescents aged 2 to 16 years diagnosed with CP were invited to participate in a pain survey. The questionnaire was based on the German Pain Questionnaire for Children, Adolescents and Parents (DSF-KJ). It was administered to children (2-11 years) by their caregivers, while adolescents (12-16 years) were asked to complete the questionnaire themselves or with the help of their caregivers. Fifty-seven of 133 children and adolescents with CP (43%) reported having pain in the past 12 months, of whom 17 (30%) reported chronic pain. Patients with Gross Motor Function Classification System (GMFCS) IV-V reported more frequent pain (p = 0.003) and higher pain intensity (p = 0.011). Lower extremity pain was the most common. Twenty-three percent of participants with pain did not receive any treatment. Pain often restricted participation, specifically by reducing sports activity in patients with GMFCS I-III, focusing attention on patients with GMFCS IV-V, and activities with the family in both GMFCS level categories. Pain is common in children and adolescents with CP and frequently restricts their participation. Therefore, it must be consistently recorded and addressed during the consultation. The goal of treatment should be not only to reduce pain but above all to increase participation.

An osteopathic assessment of lower extremity somatic dysfunctions in runners.

Runners often experience acute/chronic pain due to pre-existing structural somatic dysfunction and/or acquired various overuse injuries of the lower extremity, specifically affecting the ligaments, tendons, muscles, and bones. Common structural and function dysfunctions include but are not limited to patellofemoral pain syndrome (PFPS), Achilles tendonitis, iliotibial band syndrome (ITBS), ligamentous and muscle tears, muscle sprains/strains, stress fractures, pes planus, plantar fasciitis, and shin splints. The purpose of this study is to assess the correlation between acute and chronic pain, overuse injuries, and observational and palpatory findings upon evaluation to establish common trends of somatic dysfunctions and determine possible etiology of the pain/injury. A total of 103 individuals were recruited (54.4% female, 45.6% male) aged 23-67 years old who consistently run at least 1 mile each week. They were categorized based on their weekly mileage- Novice (1-5 miles per week), Moderate (6-15), Advanced (15+)- with the intention to have a diversity of running types and to assess the data at various levels of commitment to running. The average was 7.8 miles/week with the range at 1 to 28 miles per week. The subjects included Touro students and individuals in the community. A history was collected through an anonymous survey on the individual's running habits, chronic/acute injuries, and any other relevant medical information. Data analyzing investigators were blinded to subjects' identifying information. Additionally, an osteopathic assessment was performed by two student investigators for reliability purposes and conducted under supervision by a board-certified osteopathic physician. Analysis of the data suggested an existing correlation between the number of somatic dysfunctions and years of running. A slight correlation was found between somatic dysfunctions and miles per week, sports injuries, time per week, and lower extremity pain. Finally, statistical correlations were also identified between the presence of pes planus and limb length discrepancy with three distinct muscular hypertonicities. Runners' pains and injuries of the lower extremity are complex, and injury treatment and prevention is equally multifaceted. An association was found between both pes planus and limb length discrepancy with lower extremity muscle hypertonicity, suggesting the interrelated nature of these somatic dysfunctions. The survey concluded that many runners continue to run in pain and/or after significant injury but do not necessarily capitalize on existing support such as fitted shoes, custom arches, and osteopathic treatment that may help to minimize their risk of or treat injury. The intention of the research is to bring awareness to practitioners to the most common somatic dysfunctions such that they can recommend runners to obtain gait analyses and/or osteopathic treatments, which may not only alleviate injuries faster but also prevent future injury.

Anterior Laparoscopic Approach Combined with Posterior Approach for Lumbosacral Neurolysis: A Case Report

Background and importance: Sacral fractures often lead to injuries of the lumbosacral nerve, which will cause tremendous damage to the patient’s motor and sensory functions. At present, the most commonly used surgical method is the posterior median approach, the extent and degree of neurolysis are often insufficient, so the effect of neurolysis is not well, and the functional recovery of patients after operation is often incomplete. Clinical presentation: The patient was a 17-year-old male who accidentally fell from a height and landed on his hip. The main clinical feature of the patient was persistent radiating pain in the right lower extremity with right lower limb sensorimotor disorder. The results of the X-ray examination indicated a sacral fracture and a right pubic fracture. After the injury, the patient underwent pelvic internal fixation surgery within 72 hours. Then 6 months after the surgery, there was no significant improvement in right lower limb function, and the patient came to our hospital seeking treatment. Considering the severe lumbosacral plexus injury and the history of surgery, we performed an “Anterior surgery approach combined with posterior approach for lumbosacral neurolysis” for the patient, postoperative radiation pain disappeared completely, and there were significant improvements in the muscle strength of some muscles and sensory function. Conclusion: The relaxation of the lumbosacral plexus is usually performed through a single surgical approach, which has great limitations in the effect of relaxation. Here, we demonstrate a case in which posterior lumbar incision and anterior laparoscopic lumbosacral plexus neurolysis can benefit the patient, the lumbosacral nerve was released to a great extent. We aim to bring this case to the attention of our worldwide neurosurgical colleagues and share our surgical approach to assist those who may encounter this case in the future.

Bilateral lower extremity compartment syndrome after prolonged gynecological surgery in lithotomy position: a case report

BackgroundAcute compartment syndrome is a rare but serious complication following gynecological surgery in the lithotomy position, potentially resulting in permanent neuromuscular dysfunction or limb loss, making early recognition and prompt management essential.Case presentationA 41-year-old woman underwent a laparoscopic myomectomy for uterine fibroids, during which she was positioned in the high lithotomy and head-down position for 118 min. Six hours post-surgery, she experienced spasmodic pain and swelling in both lower extremities. Thirteen hours after surgery, her symptoms worsened, leading to the diagnosis of acute compartment syndrome in both legs. An emergency bilateral fasciotomy was performed, and the patient fully recovered within two months without any neuromuscular dysfunction.ConclusionsACS should be an important differential diagnosis for lower extremity pain after gynecologic surgery, especially with prolonged lithotomy positioning. Gynecologists should be vigilant for ACS signs and symptoms to prevent delayed diagnosis.

Surgical Management of Chronic Contained Rupture of an Abdominal Aortic Aneurysm Presenting as Right Lower Extremity Pain

Spinal Cord Stimulation vs Medical Management for Chronic Back and Leg Pain

Chronic back and lower extremity pain is one of the leading causes of disability worldwide. Spinal cord stimulation (SCS) aims to improve symptoms and quality of life. To evaluate the efficacy of SCS therapies compared with conventional medical management (CMM). MEDLINE, Embase, and Cochrane Library were systematically searched from inception to September 2, 2022. Selected studies were randomized clinical trials comparing SCS therapies with sham (placebo) and/or CMM or standard treatments for adults with chronic back or leg pain who had not previously used SCS. Evidence synthesis estimated odds ratios (ORs) and mean differences (MDs) and their associated credible intervals (CrI) through bayesian network meta-analysis. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline for network meta-analyses was followed. The primary outcomes were pain-related end points, including pain intensity (measured by visual analog scale) and proportion of patients achieving at least 50% pain relief (responder rate) in the back or leg. Quality of life (measured by EQ-5D index score) and functional disability (measured by the Oswestry Disability Index score) were also considered. A total of 13 studies of 1561 patients were included in the network meta-analysis comparing conventional and novel SCS therapies with CMM across the 6 outcomes of interest at the 6-month follow-up. Both conventional and novel SCS therapies were associated with superior efficacy compared with CMM in responder rates in back (conventional SCS: OR, 3.00; 95% CrI, 1.49 to 6.72; novel SCS: OR, 8.76; 95% CrI, 3.84 to 22.31), pain intensity in back (conventional SCS: MD, -1.17; 95% CrI, -1.64 to -0.70; novel SCS: MD, -2.34; 95% CrI, -2.96 to -1.73), pain intensity in leg (conventional SCS: MD, -2.89; 95% CrI, -4.03 to -1.81; novel SCS: MD, -4.01; 95% CrI, -5.31 to -2.75), and EQ-5D index score (conventional SCS: MD, 0.15; 95% CrI, 0.09 to 0.21; novel SCS: MD, 0.17; 95% CrI, 0.13 to 0.21). For functional disability, conventional SCS was superior to CMM (MD, -7.10; 95% CrI, -10.91 to -3.36). No statistically significant differences were observed for other comparisons. This systematic review and network meta-analysis found that SCS therapies for treatment of chronic pain in back and/or lower extremities were associated with greater improvements in pain compared with CMM. These findings highlight the potential of SCS therapies as an effective and valuable option in chronic pain management.

Ballooning and Bursting of Barrels and Pipes: A Rare Case of Suspected Vascular Ehlers–Danlos Disease

Vascular Ehler–Danlos disease (vEDS), a rare subtype of a rare disease, is a life-threatening disease, with an increased risk for spontaneous vascular or visceral rupture. These patients have fatal complications ranging from vascular aneurysms, dissection, and rupture of systemic vessels to frequent thromboembolic events, the common causes of death in these individuals with a shortened life span. In the present case, a 28-year-old male with history of shoulder dislocations and spontaneous colon perforation presented to the primary care clinic with right lower extremity swelling and pain. His history includes presentation to the emergency department with left lower leg swelling with compartment syndrome one year prior. A CT angiogram of lower extremities and abdomen revealed acute arterial extravasation of the left posterior tibial artery, indicating a ruptured aneurysm along with aneurysms of the splenic artery and left common iliac artery. He was treated with a saphenous vein graft, but was associated with post-operative complications that necessitated below-knee amputation. CT angiogram of his right leg revealed occlusion of the anterior tibial and peroneal arteries with aneurysms, and, ultimately, he was referred to a tertiary care center for aneurysm embolization. This case report emphasizes the frequent vascular complications encountered in vascular EDS patients, and thus advocates for close and regular monitoring for early referral and surgical management of their vascular anomalies. Finally, genetic counseling and screening of asymptomatic family members should be routinely implemented in these patients.

The occurrence of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) after arthroplasty mimicking a periprosthetic joint infection: A case report and literature review.

As the elderly population grows, the number of joint arthroplasty surgeries is also increasing. Periprosthetic joint infection (PJI) is a postoperative complication that occurs in 1%-2% of the arthroplasties. Once it occurs, PJI is refractory to treatment. Similar symptoms of PJI, including joint synovitis and elevated body temperature, sometimes arise because of crystal arthritis, rheumatoid arthritis, or other inflammatory diseases. Precise diagnosis is essential for determining the optimal treatment strategy. An 81-year-old female patient with a history of bilateral knee arthroplasty presented with a high fever of 38 °C and was unable to walk due to swelling and pain in the bilateral lower extremities. Infectious conditions, such as cellulitis or PJI, were suspected. Imaging findings revealed bilateral knee joint synovitis with pitting edema around the lower extremities, and cultures of bilateral joint fluids were negative. No crystals were observed in the joint fluid. Laboratory data revealed highly elevated levels of inflammatory marker; however, antinuclear antibodies, including rheumatoid factor and cyclic citrullinated peptide, were not detected. Based on bilateral synovitis with pitting edema in the lower extremities, in addition to negative culture findings and normal antinuclear antibodies, the diagnosis of remitting seronegative symmetrical synovitis with pitting edema (RS3PE) was made. Steroid therapy was performed. The dose was gradually reduced, with the improvement of the symptoms. The inflammatory reaction promptly decreased and then normalized. With improved inflammation, the symptoms of pitting edema, pain in the bilateral lower extremities, and fluid effusion of the knee joints were reduced. She was able to walk without a cane, and her activities of daily living fully recovered. High fever and synovitis after joint arthroplasty do not necessarily indicate an infectious condition. Clinicians should be familiar with the occurrence of RS3PE, regardless of whether arthroplasty is performed.

Lower urinary tract symptoms (LUTS) as a clinical feature of lumbar spinal stenosis (LSS): a prospective study with lumbar spine morphometry analysis

&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;Aim&amp;lt;/strong&amp;gt; To investigate clinical and morphometric characteristics of patients with lower urinary tract symptoms (LUTS) due to lumbar spinal stenosis (LSS).&amp;lt;br /&amp;gt;&amp;lt;strong&amp;gt;Methods&amp;lt;/strong&amp;gt; This study evaluated LSS patients using clinical assessments of motor, sensory, bladder, and bowel functions, and functional disability scores from the Oswestry Disability Index (ODI) and Swiss Spinal Stenosis Questionnaire (SSSQ). Morphometric analysis included MRI measurements of the anteroposterior diameter of the intervertebral disc and dural sac, and the modified Torg-Pavlov ratio (mTPR), with follow-up re-evaluations at 6 months.&amp;lt;br /&amp;gt;&amp;lt;strong&amp;gt;Results&amp;lt;/strong&amp;gt; Of 159 patients, 49 (30.8%) had LUTS and 110 (69.2%) were in the control group. LUTS patients had a significantly higher prevalence of neurogenic claudication (100% vs. 47.3%; p&amp;amp;lt;0.001), lower back pain (93.9% vs. 77.3%; p=0.011), and lower extremity pain (57.1% vs. 34.5%; p=0.008). The LUTS group also had higher ODI (54.0 vs. 50.0; p=0.019) and SSSQ score (44.0 vs. 34.0; p&amp;amp;lt;0.001). Morphometric analysis showed significantly lower mTPR in LUTS patients (median 0.31 vs. 0.45; p&amp;amp;lt;0.001), with an AUC of 0.704 (95%CI 0.627-0.774). mTPR&amp;amp;le;0.31 predicted surgical revision within 6 months (OR:3.4, CI: 1.2-9.8), motor deficiency (OR:2.1, 95%CI: 1.4-5.2), and persistent LUTS post-surgery (OR:4.5, 95%CI: 1.1-18.9). mTPR&amp;amp;le;0.34 was associated with worse follow-up outcome, including increased ODI (&amp;amp;beta;:3.2; 95%CI: 1.1-5.3; p=0.004) and SSSQ score (&amp;amp;beta;:4.8; 95%CI:2.1-7.5).&amp;lt;br /&amp;gt;&amp;lt;strong&amp;gt;Conclusion&amp;lt;/strong&amp;gt; LUTS patients with LSS exhibit more severe symptoms and poorer outcome, with mTPR&amp;amp;le;0.34 being a predictor of adverse clinical outcome and the need for surgical revision within 6 months.&amp;lt;/p&amp;gt;

Surgical Management of Thoracic Dorsal Arachnoid Webs: A 10-Year Single-Institution Experience

ObjectiveThoracic dorsal arachnoid webs are intradural membranes that may cause obstruction of CSF flow and spinal cord compression. While well-recognized, they are rare and there is a paucity of long-term data on their natural history and prognosis. We reviewed radiographic features, surgical indications, and pathologic specimens of patients diagnosed with focal thoracic dorsal arachnoid webs. MethodsA radiology database and surgical case logs were queried for thoracic arachnoid webs at a single hospital system for a ten-year period. A retrospective chart review was performed on identified cases. ResultsWe identified 127 patients with dorsal thoracic arachnoid webs. Arachnoid webs were radiographically classified into three morphologic types: Type 1 (54%) causing spinal cord deformity only, Type 2 (32%) producing cord deformity with myelomalacia, and Type 3 (14%) with cord deformity, myelomalacia, and syringomyelia. These arachnoid webs were commonly centered at the upper thoracic T4 segmental level. Forty-one cases (32%) required surgery, generally for thoracic myelopathy with gait instability (46%) and lower extremity numbness and pain (39%). In patients who underwent surgery, 79% experienced symptomatic improvement and 21% remained stable, after an average of 21 months follow-up evaluation. Surgical pathology revealed fibrous connective tissue (100%) with calcifications (26%) or inflammation (7%). ConclusionsThe majority in a large series of patients with dorsal arachnoid webs did not undergo surgical intervention, but those with myelomalacia and syrinx experienced radiographic and clinical deterioration without surgery. Surgery to treat symptomatic arachnoid webs results in significant clinical improvement with low surgical morbidity.

Unilateral Biportal Endoscopic Decompression for Thoracic Spinal Stenosis Secondary to Ossification of the Ligamentum Flavum

Ossification of the ligamentum flavum (OLF) in the thoracic spine is a cause of thoracic myelopathy that is more commonly found in East Asian populations (Koreans, Japanese, Chinese) than in others. Early diagnosis and sufficient surgical decompression can improve the functional prognosis for thoracic OLF. Surgical decompression is necessary and should be done as soon as the symptoms develop. There is a wide range of possible treatments, from standard open laminectomy to endoscopic decompression surgery. This video demonstrates the least invasive technique of decompressive laminectomy with bilateral decompression and removal of thoracic OLF through unilateral biportal endoscopic spinal surgery. The authors present the case of an 81-year-old male patient who presented with bilateral lower extremity weakness, numbness, pain, and ataxia. Magnetic resonance imaging and computed tomography scans of the whole spine showed the presence of OLF with severe spinal canal stenosis and a cord signal change at the T9–10 level. He underwent biportal endoscopic decompression and removal of thoracic OLF at T9–10. On the discharge day (postoperative day 7), motor power and pain had significantly improved. He could stand and independently ambulate with a walker.

A study to explore the role of a low threshold, fitness focussed physical rehabilitation intervention with protein supplementation to target physical function and frailty in people with problematic substance use and homelessness: protocol for a single-arm pre-post intervention study.

People who are homeless are more likely to experience poor mental health and addiction as well as suffering from non-communicable diseases. There is evidence of frailty and accelerated physical ageing among people experiencing homelessness. Appropriate physical rehabilitation and nutritional supplementation strategies can stabilise or reverse frailty and general physical decline, but it is not known how this type of intervention would work in practice in this population. To evaluate the feasibility and pre-post intervention impact of a low threshold physical rehabilitation intervention with protein supplementation to target physical functioning and frailty in people with problematic substance use who are experiencing homelessness. The intervention will consist of a 12-week low threshold rehabilitation programme with protein supplementation. Participants will be service users of the Ballyfermot Advance Project, a day services centre for people with addiction issues and experiencing homelessness. Primary outcomes will be feasibility including numbers recruited, retention of participants and adherence to the exercise intervention and protein supplement. Any adverse events will be recorded. Secondary outcomes will be strength and muscular mass, physical performance and lower extremity physical function, pain, frailty and nutritional status. An immediate impact may be simply a distraction from difficult circumstances and potentially an improvement of physical health of participants, which can be a conduit for the emergence of other positive behaviours and recovery. Longer term, this study will generate preliminary data on which to inform the design of a definitive randomised controlled trial of physical rehabilitation and protein supplementation, if indicated. Ethical approval was granted by the Faculty of Health Sciences Research Ethics Committee in TCD. Study findings will be disseminated through publication into an international peer-reviewed journal and presented at national and international conferences.

Endoscopic and microsurgical decompression for central lumbar spinal stenosis

Objective. To perform comparative analysis of the results of endoscopic and microsurgical decompression for lumbar spinal stenosis.Material and Methods. Design: Retrospective monocentric intra-cohort comparison of two groups of patients. The study included 99 patients aged 51–88 years with clinically significant lumbar spinal stenosis manifested by neurogenic intermittent claudication syndrome. Endoscopic decompression was performed in 51 patients, and microsurgical decompression – in 48 patients. To objectify and standardize clinical symptoms, walking distance in meters, pain syndrome and quality of life were assessed before and after surgery using standard scales and questionnaires (VAS, ODI). On the first day after surgery, back and lower limb pain were assessed, and during the observation period back and lower limb pain, quality of life and walking distance were assessed. Functional lumbar radiography was performed to exclude instability of the spinal motion segment. Using MRI, the cross-sectional area of the dural sac at the level of stenosis was measured before and after surgery. Clinical efficacy was assessed using the MCID (Minimal Clinical Important Difference) criterion. The results of the operation were followed-up for 12 months after the operation.Results. Blood loss in the endoscopic intervention group was less than in the microsurgical group. Pain in the lumbar spine and in the lower extremities decreased, and the cross-sectional area of the dural sac increased. In the first days after surgery, patients after endoscopic decompression had less severe back and lower extremity pain than patients after microsurgical decompression due to less soft tissue trauma. Pain syndrome in back 10–12 months after surgery was without statistically significant difference between the groups. Patients after endoscopic decompression had statistically significantly better quality of life according to ODI, lesser pain in the lower extremities according to VAS and longer walking distance than those in the microsurgical decompression group. Surgical treatment in both groups turned out to be effective, which is confirmed by MCID. The time of endoscopic intervention is significantly longer than that of microsurgical intervention. The length of the incision during endoscopic decompression is shorter than that of microsurgical decompression.Conclusion. A comparative analysis of the results of endoscopic and microsurgical decompression for degenerative central lumbar stenosis showed comparable effectiveness of both methods, including an increase in the spinal canal dimension and ensuring regression of clinical symptoms. The results of the comparison do not allow making a sufficiently substantiated judgment on the advantages of one of the methods, which dictates the need for further research.

7073 Treasure or Terror: Dilemmas in the Management of a Giant Parathyroid Adenoma

Abstract Disclosure: A.D. Galia: None. R. De Guzman: None. S. Suib - Salvilla: None. Background: Primary hyperparathyroidism is a common endocrine disorder with an incidence of 25 per 100,000 people in the general population. More commonly caused by parathyroid adenomas in 80-85%, giant parathyroid adenomas weighing more than 3.5 g or measuring more than 2 cm may rarely occur. There have been no reported prevalence data of parathyroid adenoma among ASEAN countries, especially in the Philippines. Clinical Case: A 43-year-old, female, Filipino, initially asymptomatic with anterior neck mass for 8 years then presented with generalized body malaise, easy fatigability, lower extremities pain and numbness. Six years ago, neck ultrasound showed left thyroid nodule; abdominal sonogram showed bilateral medullary nephrocalcinosis, with hypercalcemia, elevated intact PTH, and elevated creatinine. She was unable to undergo further workup and management until she presented a few months ago because of generalized body malaise, abdominal pain, nausea, and vomiting because of hypercalcemia and non-oliguric renal failure. Serum ionized calcium was 1.90 mmol/L (NV 1.15 - 1.30), intact PTH 2000 pg/mL, and serum creatinine 6.08 mg/dL. With unavailability of calcitonin and pamidronate, medical management of hypercalcemia included cautious hydration followed by diuresis, zoledronic acid, and cinacalcet. Sestamibi scan showed a large parathyroid adenoma. Bone densitometry showed osteoporosis (T score = below -2.5). After medical evaluation, she underwent parathyroidectomy under general anesthesia. Intact PTH level perioperatively were as follows: pre-op = 2,078.2 pg/mL; 30 mins = 477.1 pg/mL; 1 hour = 335.7 pg/mL, 1 day = 67.2 pg/mL. The resected mass was 4.2 x 2.4 x 1.6 cm and weighed 4 g; histopathology report was consistent with Parathyroid Adenoma. Post-operatively, patient did not develop hungry bone syndrome. Conclusion: Giant parathyroid adenoma is a rare condition that is usually asymptomatic but can lead to serious complications. In the Philippines, limited availability of laboratory techniques (PTH and sestamibi scan) and availability of medications for hypercalcemia may contribute to underdiagnosis and management. Early detection and treatment can help prevent further complications and improve the overall quality of life. Presentation: 6/3/2024

A Comparative Analysis of Patient-Reported Outcomes Following Free Tissue Transfer, Partial Foot Amputation, and Below-Knee Amputation in High-Risk Limb Salvage Patients.

The surgical decision for limb-salvage with free tissue transfer (FTT), partial foot amputation (PFA), or below-knee amputation (BKA) for complex lower extremity (LE) wounds hinges on several factors, including patient choice and baseline function. However, patient-reported outcome measures (PROMs) on LE function, pain, and QoL for chronic LE wound interventions are limited. Thus, the study aim was to compare PROMs in patients who underwent FTT, PFA, or BKA for chronic LE wounds. PROMs were collected via QR code for all adult chronic LE wound patients who presented to a tertiary wound center between June 2022 and June 2023. A cross-sectional analysis of patients who underwent FTT, PFA, or BKA was conducted. The 12-Item Short Survey (SF-12), PROM Information System Pain Intensity (PROMIS-3a), and Lower Extremity Functional Scale (LEFS) were completed at 1, 3, and 6 months and 1, 3, and 5 years postoperatively. Patient demographics, comorbidities, preoperative characteristics, and amputation details were collected. Of 200 survey sets, 71 (35.5%) underwent FTT, 51 (25.5%) underwent PFA, and 78 (39.0%) underwent BKA. Median postoperative time points of survey completion between FTT (6.2 months, IQR: 23.1), PFA (6.8 months, IQR: 15.5), and BKA (11.1 months, IQR: 21.3) patients were comparable (P = 0.8672). Most patients were male (n = 92, 76.0%) with an average age and body mass index (BMI) of 61.8 ± 12.6 years and 30.3 ± 7.0 kg/m2, respectively. Comorbidities for FTT, PFA, and BKA patients included diabetes mellitus (DM; 60.6% vs 84.2% vs 69.2%; P = 0.165), peripheral vascular disease (PVD; 48.5% vs 47.4% vs 42.3%; P = 0.790), and chronic kidney disease (CKD; 12.1% vs 42.1% vs 30.8%; P = 0.084). No significant differences were observed between FTT, PFA, and BKA patients in mean overall PROMIS-3a T-scores (49.6 ± 14.8 vs 54.2 ± 11.8 vs 49.6 ± 13.7; P = 0.098), LEFS scores (37.5 ± 18.0 vs 34.6 ± 18.3 vs 38.5 ± 19.4; P = 0.457), or SF-12 scores (29.6 ± 4.1 vs 29.5 ± 2.9 vs 29.0 ± 4.0; P = 0.298). Patients receiving FTT, PFA, or BKA for chronic LE wounds achieve comparable levels of LE function, pain, and QoL postoperatively. Patient-centered functionally based surgical management for chronic LE wounds using interdisciplinary care, preoperative medical optimization, and proper patient selection optimizes postoperative PROMs.

Among people with a non-traumatic lower extremity condition, is pain in the contralateral lower extremity associated with unhelpful thoughts and distress regarding symptoms?

ObjectiveWhen patients with non-traumatic lower extremity conditions express concerns regarding symptoms of the contralateral lower extremity they may be communicating fear of painful movement. Among people seeking specialty care for unilateral non-traumatic lower extremity conditions, we studied the relationship between magnitude of incapability and pain intensity in the contralateral and ipsilateral limbs and thoughts and feelings about sensations. MethodsPatients seeing a musculoskeletal specialist for any unilateral non-traumatic lower extremity condition were enrolled. We used multivariable analysis to identify aspects of unhelpful thinking and feelings of distress associated with contralateral and ipsilateral pain intensity and magnitude of capability accounting for demographic factors. ResultsGreater pain intensity in the contralateral limb, greater pain intensity in the ipsilateral limb, and higher magnitude of incapability were all associated with greater distress regarding symptoms. ConclusionsWhen patients voice concerns about pain in the contralateral limb, they may be signaling feelings of worry or despair regarding symptoms. Practice implicationsConcerns about pain in the contralateral limb can prompt clinicians to explore feelings of worry or despair regarding symptoms, an important and modifiable aspect of musculoskeletal illness.

Efficacy and Safety of Biportal Endoscopic Decompressive Laminectomy in Octogenarians With Severe Lumbar Spinal Stenosis.

Lumbar spinal stenosis (LSS) is prevalent among octogenarians, causing significant pain and disability. Surgical intervention is often required because of the ineffectiveness of conservative treatments. This study investigates the efficacy and safety of biportal endoscopic decompressive laminectomy (BED) in octogenarians with severe LSS, evaluating its potential as a minimally invasive surgical option. This retrospective study included 107 patients aged 80 years or older who underwent BED for LSS between March 2017 and December 2022. Data were collected from electronic medical records, including demographic information, clinical outcomes, and surgical details. Patients with fractures, infectious spondylitis, herniated discs, and follow-up less than 12 months were excluded. Clinical outcomes were assessed using the visual analog scale, Oswestry Disability Index, European Quality of Life-5 Dimensions, and painDETECT at baseline and at 3, 6, and 12 months after surgery. The mean age of the 107 patients was 84.1 years, with 59% being women. Significant improvements were observed in visual analog scale scores for lower back and lower extremities pain, Oswestry Disability Index, European Quality of Life-5 Dimensions, and painDETECT scores, indicating reduced pain, decreased disability, and enhanced quality of life. There were no significant differences in outcomes between patients aged 80 to 84 and those 85 or older. Surgery-related outcomes such as operation time, blood loss, and complications were similar in both age groups. BED is a safe and effective treatment for LSS in octogenarians, providing significant pain relief and functional improvement. This minimally invasive technique is also viable for patients older than 85 years, without increased risk of complications, supporting its broader indications in managing LSS in the elderly. This study highlights the efficacy and safety of BED for LSS in octogenarians, demonstrating its potential to improve quality of life and function with low risks, making it a feasible option for elderly patients.

Percutaneous endoscopic transforaminal decompression surgery for symptomatic double-level lumbar spinal stenosis with ossification.

This study aimed to explore the short-term effects of percutaneous endoscopic transforaminal decompression (PETD) for the treatment of symptomatic double-level lumbar spinal stenosis (LSS) with ossification. Twenty-eight patients diagnosed with double-level lumbar spinal stenosis who underwent double-level PETD surgery between January 2021 and January 2023 at our institution. General information, such as age, sex, disease duration, hospitalization time, and operation time, was recorded. Magnetic resonance imaging (MRI) dural sac cross-sectional area (DSCA) was recorded to assess the degree of spinal canal decompression. The White-Panjabi scoring system (WP) was used to assess preoperative and postoperative lumbar spine stability. Pre- and postoperative visual analog scale (VAS) and Oswestry Disability Index (ODI) scores were recorded to assess symptom improvement, and surgical efficacy was evaluated using the modified Macnab evaluation criteria at the 1-year postoperative follow-up. The types and risks of complications were also recorded. The patient's 1-year postoperative follow-up MRI showed that both L3/4 and L4/5 DSCA were significantly enlarged compared with preoperative values (P < .001). There was no significant difference in the WP scores at 3 months postoperatively compared with those preoperatively (P > .05). The VAS scores for hip and lower extremity pain at 3 days, 3 months, and 1 year postoperatively were significantly lower than those preoperatively (P < .001), and the ODI scores at 3 months and 1 year postoperatively were significantly lower than those preoperatively (P < .001). There were no significant differences in hip pain, lower extremity pain VAS scores, or ODI scores between the postoperative follow-up time points (P > .05). There was 1 case of lower limb numbness and 1 case of neuroedematous pain in the postoperative period, and all patients had no complications, such as dural sac tear, infection, or recurrence. The 1-year postoperative follow-up was assessed as excellent in 17 cases, good in 9 cases, and possible in 2 cases using the modified Macnab criteria, with an excellent rate of 92.9%. The efficacy of double-level PETD for symptomatic double-level LSS is clear, the local stability of the lumbar spine is less affected, and the risk is low, which can reduce the chances of reoperation in patients. Thus, it is a recommended surgical procedure.
