Clinical Outcomes Following Open Olecranon Bursa Excision for Septic and Aseptic Olecranon Bursitis: An Observational Study

Background and objective Olecranon bursitis (aseptic or septic) is caused by inflammation in the bursal tissue. While it is typically managed with conservative measures, refractory cases may indicate surgical intervention. There is currently limited research about outcomes following bursal excision for both septic and aseptic etiologies. In light of this, the purpose of this study was to determine if patients experienced improvement following surgical olecranon bursa excision and to compare outcomes between septic and aseptic forms. Materials and methods A retrospective review was performed involving patients who underwent olecranon bursa excision from 2014 to 2021. Demographic data, patient characteristics, surgical data, and outcome-related data were collected from the medical records. Patients were classified into subgroups based on the type of olecranon bursitis (septic or aseptic). Preoperative and one-year postoperative 12-item short-form survey (SF-12) results and range of motion (ROM) outcomes were evaluated for the entire cohort as well as the subgroups. Results We included 61 patients in our study and found significant improvement in the Physical Component Scale 12 (PCS-12) score for all patients (42.0 vs. 45.5, p=0.010) following surgery. However, based on subgroup analysis, the aseptic group improved in PCS-12 following surgery (41.5 vs. 46.8, p<0.001), but the septic group did not (43.6 vs. 40.5, p=0.277). No improvements were found in the Mental Component Scale 12 (MCS-12) scores following surgery in either group. Eighteen of the 61 patients experienced postoperative complications (29.5%), but only 6.5% required a second surgical procedure. Specifically, 14 of the 18 complications occurred in the aseptic group while two septic and two aseptic patients required additional surgeries. Elbow ROM did not change significantly after surgery but more patients were found to have full ROM postoperatively (83.0% to 91.8%, p=0.228). Conclusion Our findings suggest that patients with refractory olecranon bursitis, particularly if aseptic, tend to gain significant physical health benefits from open bursectomy.

Surgical Management of Scapulothoracic Bursitis in a Patient with Systemic Lupus Erythematosus: A Case Report

Scapulothoracic bursitis involves inflammation of the scapulothoracic bursa caused by overuse of the shoulder or traumatic injury. Conservative management is recommended initially, and a surgical approach, such as bursectomy or scapular angle resection, is indicated later. Scapulothoracic bursitis in a patient with systemic lupus erythematosus (SLE) has been rarely reported in the literature. A 34-year-old woman was hospitalized in our hospital for a palpable mass on the right side of her back. She had a history of SLE, which was diagnosed and treated with medication 13 years prior. Chest magnetic resonance imaging (MRI) revealed fluid collection measuring 6.0 cm × 6.0 cm × 2.0 cm between the rib cage and subscapularis muscle. Histopathological examination identified the mass as bursitis with cystic degeneration. Surgical excision was performed at the infrascapular area. About 11 months later, the mass recurred in the same area. Surgical excision was again performed in the same way as before, and the same diagnosis was confirmed. Every 6 months, ultrasound examination is being conducted to assess for recurrence. The patient has not had any further complications or a relapse for the last 3 years. Prompt bursectomy can be a definitive and long-lasting treatment option for scapulothoracic bursitis accompanied by SLE.

Histological changes and neural elements in the subacromial bursa on patients with rotator cuff tear: Pilot study

OBJECTIVE

This study aimed to investigate the neural elements of the subacromial bursa (SAB) in rotator cuff tears.

MATERIALS AND METHODS

Twenty patients with rotator cuff tears were recruited, and their visual analog scale (VAS) score, duration of symptoms, and range of motion (ROM), including flexion, external rotation, and internal rotation were evaluated. Tear size was measured using magnetic resonance imaging (MRI). The SAB specimens obtained during arthroscopic rotator cuff repair were studied using routine hematoxylin and eosin staining and immunohistochemistry (S-100 protein and PGP 9.5 protein). The SAB specimen for the control group was obtained from 2 fresh cadavers and 2 patients with acute humeral shaft fracture. The Mann-Whitney U test was applied to assess the difference between histological findings of the rotator cuff tear group and control group. The correlation between the histological findings and clinical features was evaluated using the Spearman correlation coefficient.

RESULTS

The mean duration of symptom was 10.2 ± 6.4 months. The preoperative average VAS score was 2.9 ± 1.2. The degrees of preoperative ROM in forward flexion and external and internal rotations were 143.8 ± 19.5, 49.5 ± 23.1, and -4.3 ± 4.2, respectively. The tear was 2.0 ± 0.9 cm. For histological findings, the number of neural elements per low power field in the rotator cuff tear group was significantly less than the control group in both immunohistochemical stainings (S-100: 0.5 ± 0.7 vs 2.8 ± 0.5, p < .01; PGP 9.5: 0.4 ± 0.7 vs 3.5 ± 0.6, p < .01). During the correlation analysis, the number of neural elements in the PGP 9.5 staining was negatively correlated with the ROM in forward flexion and external rotation.

CONCLUSION

This study revealed that chronic rotator cuff tears may induce degeneration of neural elements in SAB.

Open Versus Arthroscopic Surgical Management for Recalcitrant Trochanteric Bursitis: A Systematic Review

Background

While excision of the trochanteric bursae to treat lateral hip pain has increased in popularity, no comparison exists between the surgical outcomes and complications of the open and arthroscopic techniques involving trochanteric bursectomy. The purpose of this study was to determine the efficacies and complication rates of arthroscopic and open techniques for procedures involving trochanteric bursectomy.

Methods

The terms "trochanteric," "bursectomy," "arthroscopic," "open," "outcomes," and "hip" were searched in five electronic databases. Fifteen studies from 120 initial results were included. Patient-reported outcomes (PRO), pain, satisfaction, and complications were included for analysis.

Results

Five hundred-two hips in 474 total patients (77.7% female) were included in this study. The average age was 54. The fourteen distinct PRO scores that were reported by the included studies improved significantly from baseline to final mean follow-up (12-70.8 months for open; 12-42 months for arthroscopic) for both approaches, demonstrating statistically significant patient benefit in a variety of hip arthroscopy settings (P > 0.05). The complication rates of all procedures ranged from 0%-33% and failure to improve pain ranged from 0%-8%. Patient satisfaction with surgery was high at 95% and 82% reported a willingness to undergo the same surgery again. No significant mean differences were found between the open and arthroscopic techniques.

Conclusion

The open and arthroscopic approaches for trochanteric bursectomy are both safe and effective procedures in treating refractory lateral hip pain. No significant differences in PROs, pain, total complications, severity of complications, and total failures were seen between technique outcomes.Level of Evidence: IV.

Saline Load Test and Quilting Sutures to Treat Intractable Lateral Malleolar Bursitis

The purpose of this study was to evaluate the clinical outcomes of patients with intractable lateral malleolar bursitis who were treated using the intraoperative saline load test to find communication between the bursal sac and the ankle joint and the quilting sutures after bursectomy to reduce the dead space. We reviewed a total of 28 patients who had been treated with quilting sutures after bursectomy between April 2014 and June 2017. When there was capsular opening detected with the saline load test, it was closed with sutures or augmented with periosteum. On the final follow-up office visit, the lateral malleolus was examined for the recurrence of bursitis. Patient medical records were reviewed for postoperative wound dehiscence, skin necrosis, infections, and nerve symptoms. The saline load test was positive in 11 (42%) cases. The mean foot function index improved from 25.94 ± 20.46 to 11.73 ± 5.27 (p = .003). Fourteen (54%) patients were very satisfied with the results, 9 (35%) were satisfied, 2 (8%) rated their satisfaction as fair, and 1 (4%) was dissatisfied. No cases required skin graft or flap surgery. Intractable lateral malleolar bursitis was successfully treated using the saline load test and quilting sutures after bursectomy. Closure of the capsular opening prevented fluid drainage around the wound. Quilting sutures after bursectomy reduced dead space underneath the wound to prevent fluid accumulation and promoted healing of the skin on the underlying soft tissue.

Clinical Management of Olecranon Bursitis: A Review

Olecranon bursitis is a disease characterized by inflammation of the olecranon bursa, most often due to microtrauma. Although it is a common condition, there is a lack of evidence-based recommendations for the management of nonseptic olecranon bursitis. The condition is often self-limited and resolves with conservative methods such as rest, ice, compression, orthosis wear, and nonsteroidal anti-inflammatory medications. Older studies have shown resolution of symptoms with intrabursal corticosteroid injections and surgical bursectomy. More recent literature has demonstrated adverse effects of intrabursal injections and surgery compared with noninvasive management for initial treatment of nonseptic olecranon bursitis. In order to better tailor decision-making, it is important that hand surgeons understand the comparative efficacies of each option for management of nonseptic olecranon bursitis.

Factors associated with revision surgery for olecranon bursitis after bursectomy

BACKGROUND

The primary aim of our study was to identify the factors associated with revision surgery after bursal excision in patients with olecranon bursitis. The secondary aims were to describe the revision rate after bursectomy and to assess which factors are associated with flap surgery after bursectomy and describe the most common complications after bursectomy of the olecranon bursa.

METHODS

We included 191 adult patients with olecranon bursitis who underwent olecranon bursa excision between January 2002 and October 2018. Patients who were pregnant, patients with incomplete records of the primary surgical procedure, and patients who underwent bursectomy during elbow arthroplasty were excluded. After manual chart review, we found that 22 patients had undergone revision surgery. Bivariate analysis was performed to assess the association between revision surgery and patient characteristics, comorbidities, and clinical characteristics. Additionally, we collected data regarding postoperative complications and intraoperative variables such as the use of drains, vacuum assisted closure therapy, and flap surgery.

RESULTS

The overall revision rate in our cohort was 11.5% (22 of 191 patients). Bivariate analysis showed that patients who underwent revision surgery were more frequently women (P = .004), more often had a history of ipsilateral (P = .020) or contralateral (P = .012) olecranon bursitis, and more often received a diagnosis of rheumatoid arthritis (P = .001) or diabetes mellitus (P = .019). The most common complications were delayed wound healing (n = 8, 4.2%) and osteomyelitis (n = 8, 4.2%). Flap surgery was performed in 5 patients (2.6%). Bivariate analysis showed that patients with rheumatoid arthritis underwent flap surgery more frequently (P = .011).

CONCLUSION

The revision rate after bursectomy for olecranon bursitis was 11.5% (22 of 191 patients). Patients with rheumatoid arthritis, diabetes mellitus, or a history of ipsilateral and contralateral olecranon bursitis and female patients underwent revision surgery after bursectomy for olecranon bursitis more frequently. In addition, patients with rheumatoid arthritis underwent flap surgery after bursectomy more frequently.

Evaluation of a receptor gene responsible for maternal blood IgY transfer into egg yolks using bursectomized IgY-depleted chickens

In avian species, maternal immunoglobulin Y (IgY) is transferred from the blood to the yolks of maturing oocytes; however, the mechanism underlying this transfer is unknown. To gain insight into the mechanisms of maternal IgY transfer into egg yolks, IgY-depleted chickens were generated by removing the bursa of Fabricius (bursectomy) during egg incubation, and their egg production and IgY transport ability into egg yolks were determined. After hatching, blood IgY concentrations of the bursectomized chickens decreased gradually until sexual maturity, whereas those of IgA remained low from an early stage of growth (from at least 2 wk of age). Chickens identified as depleted in IgY through screening of blood IgY and IgA concentrations were raised to sexual maturity. At 20 wk of age, both blood and egg yolk IgY concentrations in the IgY-depleted group were 600-fold lower than those of the control group, whereas egg production did not differ between the groups. Intravenously injected, digoxigenin-labeled IgY uptake into the egg yolk was approximately 2-fold higher in the IgY-depleted chickens than in the controls, suggesting that IgY depletion may enhance IgY uptake in maturing oocytes. DNA microarray analysis of the germinal disc, including the oocyte nucleus, revealed that the expression levels of 73 genes were upregulated more than 1.5-fold in the IgY-depleted group, although we could not identify a convincing candidate gene for the IgY receptor. In conclusion, we successfully raised IgY-depleted chickens presenting a marked reduction in egg yolk IgY. The enhanced uptake of injected IgY into the egg yolks of the IgY-depleted chickens supports the existence of a selective IgY transport mechanism in maturing oocytes and ovarian follicles in avian species.

Bursectomy Versus Nonbursectomy for Gastric Adenocarcinoma: A Single-Center, Propensity-Score Matched Cohort Study in China

Background: The therapeutic value of bursectomy remains controversial for patients with gastric cancer. Therefore, the purpose of our study was to explore the safety and survival benefits of bursectomy. Materials and Methods: A total of 943 patients with gastric adenocarcinoma were included in our study, and all patients were operated on by high-quality gastrointestinal surgeons. The factors associated with overall survival (OS) were determined using the Kaplan-Meier method. In addition, patients in the bursectomy group and nonbursectomy group were matched with 1:1 propensity score matching for sex, age, tumor location, type of operation, tumor size, degree of differentiation, and pathological stage to reduce the possibility of choice bias. Results: Among the 943 eligible patients, 188 (19.9%) underwent bursectomy and 755 (80.1%) did not. In all patients, the number of retrieved lymph nodes (P = .0596), blood loss volume (P = .0896), operation time (P = .0747), number of postoperative complications (P = .626), and OS in the bursectomy group were similar to those in the nonbursectomy group. After a stratified analysis of TNM grade and T stage, it was found that bursectomy could lead to survival benefits for patients with stage T4 disease (P = .0398). Conclusions: Bursectomy does not increase the amount of blood loss, operation time, or incidence of postoperative complications. This procedure is an extended and safe surgical method for gastric adenocarcinoma. Bursectomy does not improve the survival of all patients, but for patients with stage T4 disease, bursectomy can provide survival benefits.

Ultrasound-Guided Minimally Invasive Surgical Resection of Retrocalcaneal Bursitis: A Preliminary Comparison With Traditional Open Surgery

Posterior heel pain is a common complaint that is often caused by overuse injuries. In such cases, the retrocalcaneal bursa is compressed and chafed repeatedly, leading to local inflammation. Sonography is a popular imaging tool used to study the pathology of soft tissues, and it can be used to assist in diagnosing bursitis because of its accuracy. Herein, we report an innovative method to treat retrocalcaneal bursitis under ultrasound guidance. Ten patients with posterior heel pain for >6 months who failed conservative treatment received this ultrasound-guided minimally invasive surgery. An endoscopic puncher and burr were inserted under ultrasound guidance via a stabbing wound, and the swollen retrocalcaneal bursa and bony prominence were resected. The patients were able to ambulate and undergo a rehabilitation program 2 weeks postoperatively. In the patients who underwent this ultrasound-guided minimally invasive surgery, both the average surgical time and average hospital stay were shorter than in those (n = 12) who underwent open surgery. In outcome rating assessment, the American Orthopaedic Foot & Ankle Society (AOFAS) pain score and total AOFAS ankle-hindfoot score were improved in the ultrasound-guided minimally invasive surgery group compared to the open surgery group at 2 months postoperatively. Other advantages included lesser wound pain, shorter hospital stay, faster recovery time, and minimal blood loss. Accordingly, ultrasound-guided surgery appears to be a good option for the treatment of retrocalcaneal bursitis.

Changing Trends in Gastric Cancer Surgery

Gastric cancer is one of the most common causes of cancer-related death. It requires multimodal treatment and surgery is the most effective treatment modality. Radical surgery includes total or subtotal gastrectomy with lymph node dissection. The extent of lymphadenectomy still remains controversial. Eastern surgeons have performed D2 or more extended lymphadenectomy while their Western colleagues have performed more limited lymph node dissection. However, the trend has been changing in favour of D2 lymph node dissection in both hemispheres. Currently, D2 is the recommended type of lymphadenectomy in experienced centres in the west. In Japan, D2 lymph node dissection is the standard surgical approach. More extensive lymphadenectomy than D2 has not been found to be associated with improved survival and generally is not performed. Bursectomy and splenectomy are additional controversial issues in surgical performance, and trends regarding them will be discussed. The performance of bursectomy is controversial and there is no clear evidence of its clinical benefit. However, a trend toward better survival in patients with serosal invasion has been reported. Routine splenectomy as a part of lymph node dissection has largely been abandoned, although splenectomy is recommended in selected cases. Minimally invasive surgery has gained wide popularity and indications for minimally invasive procedures have been expanding due to increasing experience and improving technology. Neoadjuvant therapy has been shown to have beneficial effects and seems necessary to provide a survival benefit. Diagnostic laparoscopy should be kept in mind prior to treatment.

Olecranon bursitis: a systematic overview

BACKGROUND

Olecranon bursitis is a common condition where the bursal cavity, superficial to the olecranon, becomes inflamed. This can occur either with or without infection and has been given pseudonyms relating to the repeated minor trauma from external pressure that often predisposes. As a result of the multiple aetiologies, olecranon bursitis can present to any medical specialty with reasonable frequency and, although many therapies are described, a single, evidence-based and standardized treatment pathway is not well described.

METHODS

We summarize the key points within the literature and subsequently propose an evidence-based treatment pathway.

RESULTS

Relevant evidence is presented from appropriate publications to add rational to existing decision-making processes, together with personal experience and suggested operative bursectomy techniques from an established upper limb surgeon. The common and significant aetiologies are summarized and, in particular, red flag symptoms are highlighted by way of warning to the unsuspecting investigator.

CONCLUSIONS

The conclusion is provided in diagrammatic form, providing a suggested treatment pathway from history and examination through to operative intervention.
