Fifty consecutive patients with RA and clinical wrist synovitis were randomly allocated to either receive an injection of glucocorticoid into the radiocarpal joint or have the same amount of drug divided into the radiocarpal and midcarpal joints. Inferior radioulnar joint synovitis was treated with extra steroid injection only in the latter group. Patient's and doctor's assessments as well as ultrasonography improved significantly at month 3 in both groups. A statistical difference between the groups was found in the midcarpal joint measurement favouring the extra midcarpal injection. Ten wrists (20%) were normal when assessed with ultrasound at month 3 while 34 wrists (68%) were normal on clinical assessment. [ABSTRACT FROM AUTHOR]

Purpose: Laser ablation is one of the newest and most advanced minimally invasive techniques in treating pilonidal sinus disease (PSD). Most studies on the subject have small sample sizes and relatively short follow-up times, making evaluation of long-term healing rates and recurrences difficult. Furthermore, long-term results for laser surgery of PSD are still lacking. The aim of this study was to retrospectively report long-term follow-up results for PSD treatment by radial laser surgery., Methods: We retrospectively studied the medical records of 83 patients who underwent the radial laser procedure for PSD between January 2017 and September 2019. Our follow-up time was a median of 5.2 years, range 1.5 to 7.4 years., Results: Twelve patients had a PSD recurrence after their laser procedure, which gives a recurrence rate of 14.5% (95% CI 8.2%-23.2%). These recurrences appeared at a median 12.2 months after the laser procedure, range 4.2 to 51 months. A total of 23 patients (27.7%; 95% CI 19.0-38.0) underwent a reoperation, 11 patients due to postoperative infection or prolonged recovery and 12 patients due to PSD recurrence. Recurrent PSD and spillage of pus during operation were statistically significantly associated with the need for a second operation., Conclusion: Radial laser surgery provides a minimally invasive treatment option with an acceptable recurrence rate in long-term follow-up., (© 2024.

Objectives: We aimed to prospectively evaluate the prevalence of long-standing groin pain and related MRI findings in contact sports., Methods: This case-control study followed three male elite-level soccer, ice-hockey and bandy teams (102 players) for 2 years. All athletes with long-standing groin pain lasting >30 days and age-matched controls (1:3) from the same teams were examined clinically, using pelvic MRI and Hip and Groin Outcome Scores (HAGOS). Primary outcome measures were annual prevalence of groin pain and underlying MRI findings., Results: The annual prevalence of chronic groin pain was 7.5%. Training characteristics and pain scores of athletes were similar in all teams. On MRI, there was no significant difference in the percentage of pubic bone marrow oedema (p = 0.80) between symptomatic players (8/15; 53%) versus controls (20/43; 47%), but adductor tendinopathy and degenerative changes at the pubic symphysis were twice more common among players with pain. Rectus muscle or iliopsoas pathology were seldom observed. Lower HAGOS subscales (p < 0.01) were recorded in players who experienced groin pain compared with the controls., Conclusion: Long-standing groin pain was observed annually in 1 of 14 athletes in contact sports. Abnormalities in the pubic symphysis were common MRI findings in both symptomatic and asymptomatic players., Trial Registration Number: NCT02560480., Competing Interests: Competing interests: None declared.

Background: Athletic pubalgia is typically associated with male athletes participating in contact sports and less frequently with females. Endoscopic surgery may fully treat the patient with athletic pubalgia., Purpose: To perform an outcomes analysis of magnetic resonance imaging (MRI) and endoscopic surgery in female patients with athletic pubalgia., Study Design: Cohort study; Level of evidence, 3., Methods: Fifteen physically active female patients (mean age, 37 years) with athletic pubalgia were treated surgically via placement of total extraperitoneal endoscopic polypropylene mesh behind the injured groin area. The presence of preoperative bone marrow edema (BME) at the pubic symphysis seen on MRI was graded from 0 to 3 and correlated with pain scores after surgery. The outcome measures were pre- and postoperative pain scores and recovery to daily activity between 1 and 12 months after surgery. Results were compared with previously published scores from male athletes (n = 30)., Results: With the exception of lower body mass index, the females with (n = 8) and without (n = 7) pubic BME had similar patient characteristics to the corresponding males. Mean inguinal pain scores (0-10) before surgical treatment were greater in females than males (during exercise, 7.8 ± 1.1 vs 6.9 ± 1.1; P = .0131). One month after surgery, mean pain scores for females were still greater compared with males (2.9 ± 1.7 vs 1.3 ± 1.6; P = .0034). Compared with female athletes with normal MRI, pubic BME was related to increased mean preoperative pain scores (8.13 ± 0.99 vs 6.43 ± 1.2; P = .0122). After 1 year, surgical outcomes were excellent or good in 47% of women., Conclusion: Endoscopic surgery was helpful in half of the females with athletic pubalgia in this study. The presence of pubic BME may predict slightly prolonged recovery from surgery., Competing Interests: The authors declared that they have no conflicts of interest in the authorship and publication of this contribution.

Background: Chronic groin pain in athletes presents often a diagnostic and therapeutic challenge. Sportsman's hernia (also called "athletic pubalgia") is a deficiency of the posterior wall of the inguinal canal, which is often repaired by laparoscopic mesh placement. Endoscopic mesh repair may offer a faster recovery for athletes with sportsman's hernia than nonoperative therapy., Methods: A randomized, prospective study was conducted on 60 patients with a diagnosis of chronic groin pain and suspected sportsman's hernia. Clinical data and MRI were collected on all patients. After 3 to 6 months of groin symptoms, the patients were randomized into an operative or a physiotherapy group (n = 30 patients in each group). Operation was performed using a totally extraperitoneal repair in which mesh was placed behind the symphysis and painful groin area. Conservative treatment included at least 2 months of active physiotherapy, including corticosteroid injections and oral anti-inflammatory analgesics. The outcome measures were pre- and postoperative pain using a visual analogue scale and partial or full recovery to sports activity at 1, 3, 6, and 12 months after randomization., Results: The athletes in both treatment groups had similar characteristics and pain scores. Operative repair was more effective than nonoperative treatment to decrease chronic groin pain after 1 month and up to 12 months of follow-up (P < .001). Of the 30 athletes who underwent operation, 27 (90%) returned to sports activities after 3 months of convalescence compared to 8 (27%) of the 30 athletes in the nonoperative group (P < .0001). Of the 30 athletes in the conservatively treated group, 7 (23 %) underwent operation later because of persistent groin pain., Conclusion: This randomized controlled study indicated that the endoscopic placement of retropubic mesh was more efficient than conservative therapy for the treatment of sportsman's hernia (athletic pubalgia)., (Copyright © 2011 Mosby, Inc.

Objective: Bone marrow edema (BME) at the pubic symphysis on magnetic resonance imaging (MRI) is usually associated with groin pain and stress injury of the pubic bone. Little is known of the pubic MR imaging findings of asymptomatic heavy training athletes in contact sports., Materials and Methods: Pelvic MRI of male asymptomatic soccer (n=10), ice hockey (n=10), bandy (n=10) and female floor-ball players (n=10) were compared with non-athlete controls (10 males, 10 females) without groin pain to analyse the presence of BME (on a four-point scale). To study the possible changes of BME directly following heavy physical activity, 10 bandy players underwent MRI before and immediately after a 2-h training session., Results: Magnetic resonance imaging showed minimal BME (grade 1) at the pubic symphysis in 19 of the 40 athletes (48%). Two soccer and 2 ice hockey players (20%) had moderate grade 2 pubic edema, but severe grade 3 BME findings were not found. Also 10 out of 20 (50%) of controls had grade 1 BME. The extent of increased signal was equally distributed in the asymptomatic athletes of different contact sports and controls. A heavy 2-h training session did not cause any enhanced signal at the pubic symphysis., Conclusions: This study indicates that the presence of grade 1 pubic BME was a frequent finding in contact sports and comparable to that in non-athletes. Grade 2 BME was found only in asymptomatic athletes undergoing heavy training.

Background: Preoperative core needle biopsies may increase the risk of surgical site infection (SSI) in breast cancer surgery. The purpose of this randomized trial was to determine whether a prophylactic antibiotic would prevent SSI under these conditions., Methods: Imaging-guided multiple core needle biopsies were performed one to two weeks prior to surgery to obtain confirmation of the presence of breast cancer. Then the patients were randomized to receive either a single intravenous dose of 1.0 g of dicloxacillin (n = 144) or placebo infusion of saline (n = 148) 30 min prior to operation. After breast surgery, incisional morbidity was monitored for 30 days. The number of SSIs was compared with that in 672 patients treated before the implementation of core needle biopsies., Results: The patient characteristics and risk factors for SSI were similar in the antibiotic prophylaxis and placebo groups. The incidence of SSI was 7.2% (21/292) in the prospective trial compared with 6.8% (46/672) in the retrospective cohort (p = 0.890). The incidence of postoperative SSIs was 5.6% (8/144) in the dicloxacillin group and 8.8% (13/148) in the placebo group (p = 0.371). For the first two weeks, there was a non-significant trend to fewer SSIs in the antibiotic group (n = 1) than the placebo group (n = 4). Body mass index, smoking, or previous illness did not affect the likelihood of SSI., Conclusions: Core needle biopsy did not increase the incidence of SSI. Antibiotic prophylaxis did not prevent SSI, probably because so few infections occurred.

Background: Osteitis pubis is characterized by diffuse pain, inflammation, and bony changes in the pubic symphysis. Bone marrow edema in magnetic resonance imaging is associated with stress injury and osteitis of the pubic bone., Hypothesis: Laparoscopic mesh repair decreases inflammation and pain in the pubic periosteum. The presence of extensive bone marrow edema may correlate with the severity of symptoms and may guide the surgical treatment of osteitis pubis., Study Design: Case control study; Level of evidence, 4., Methods: Surgery (n = 8) was performed by placement of totally extraperitoneal endoscopic mesh behind the symphysis. Nonoperative treatment (n = 8) included physical therapy and corticosteroids. Preoperative and postoperative pain was measured by the visual analog scale. Athletes were followed up from 1 to 6 years (mean, 2.7 years). All magnetic resonance imaging scans were analyzed blindly by 2 radiologists. Twenty asymptomatic ice hockey or soccer players served as controls in magnetic resonance imaging., Results: The patients treated surgically had higher preoperative pain scores than did the patients treated conservatively. Seven of 8 athletes (88%) treated surgically returned to sport activities after 2 months of convalescence. No complications were associated with surgery. In the nonoperative group, 4 patients (50%) still had disabling symptoms after 1 year of follow-up, and they stopped their elite sports during 3 years of follow-up. The presence of bone marrow edema was distributed in the surgical (100%), nonoperative (88%), and asymptomatic athletes (65%) with no statistical difference between the groups., Conclusion: This study indicated that the placement of retropubic mesh was an efficient method for the treatment of severe pubic enthesopathy in athletes. Abnormal magnetic resonance imaging findings were also common in asymptomatic athletes, which decreases the value of magnetic resonance imaging in surgical decision-making.

Objective: To examine a contrast medium method using a glucocorticoid-air-saline mixture and ultrasound imaging (GAS-graphy) for the verification of palpation-guided injections in different joints and to assess the inter-reader reliability of the method., Methods: A palpation-guided injection of an air-steroid-saline mixture was given into a joint or tendon sheath of 133 consecutive patients. The dynamic ultrasound monitor images of the joints and tendons involved were videotaped before and after the injection. A rheumatologist and two radiologists analyzed separately the video clips of each patient, under blinded conditions. The readers evaluated the accuracy of the injections and the difficulty of the reading process. The inter-reader agreement was assessed by calculating the percentual values and overall kappa coefficient between the readers., Results: The overall accuracy of the successful injections was 76%, 80% and 82 % evaluated by the three readers. In six out of the ten injection sites the accuracy was higher than 80%. The clarity of the method evaluated by the readers was 8, 8 and 8.5 on a scale from 0 to 10. The inter-reader agreement assessed by percentual values was 84.2%, 85.0% and 88.7%. The kappa coefficient between all readers was 0.595 showing moderate agreement., Conclusion: The GAS-graphy method for the verification of palpation-guided injections is a simple procedure performable to any joint site and the result can be seen immediately on the monitor after the injection. The reliability of the method is good and it can be used in developing injection techniques as well as in medical or nurse education. The method can be used as an alternative for the radiographic contrast medium method in verifying successful palpation-guided intra-articular injections.

Objectives: To investigate experimentally the echogenicity of air, a steroid suspension and physiological saline mixed with water in order to find the best contrast medium for injections. To show the practical applications of an airsteroid-saline mixture as a contrast medium in rheumatology., Methods: In vitro. First, quality assurance measurements were conducted twice on the ultrasound (US) equipment. Subsequently air, a steroid suspension, or physiological saline mixed with water, first alone and then in different combinations, were examined with US using quantitative image analysis. Clinical. The effectiveness of an air-steroid-saline mixture as contrast medium in ultrasonography was tested in joint, bursa and tendon sheath injections., Results: In vitro. Based on the quality assurance measurements the physical performance of the US equipment was excellent. Verified visually and quantitatively the mixture of air, steroid and saline produced the best contrast on US. The importance of air bubbles producing contrast was obvious. Clinical application. Firstly, visualisation of the contrast medium with US made it possible to follow in real-time the passage of a drug to the target area. Secondly, the use of the contrast method verified the presence of steroid in the synovial target intended after a blind injection. Thirdly, anatomical and pathologic anatomical connections could be visualized using this contrast medium in the wrist, shoulder, knee, ankle and foot joint, Conclusions: Verification of US system performance by quality assurance measurement is essential for US imaging. The air-steroid-saline contrast medium method of ultrasound scanning is a somewhat invasive, but inexpensive and rapid method. It can verify the existence or non-existence of an air-steroid-saline contrast medium in the desired place and in adjacent structures, thus showing possible pathologic anatomic connections. The method has a diagnostic and therapeutic value, and expands the interventional spectrum of sonographic imaging.

Background and Aims: Polypropylene mesh repair of large incisional ventral hernias has become increasingly popular. Long-term effects of the mesh on pain and abdominal muscles are not known., Patients/methods: Retromuscular pre-peritoneal polypropylene mesh was placed by open technique in 84 consecutive patients with large ventral hernias (mean defect size 130 cm(2)). We re-examined the patients after a mean follow-up time of 3 years to find out the frequency of recurrence and chronic pain. We measured the thickness of abdominal muscles of eight patients preoperatively, and postoperatively after 1 year, using magnetic resonance imaging (MRI)., Results: Recurrent hernias had appeared in four patients (5%) at follow-up. Nine patients (13%) needed occasional pain-relieving drugs, but only three (4%) suffered persistent, severe, pain from the mesh. Some limitation during leisure-time physical activities was found in 10% of patients. Only ten patients (12%) were re-operated on because of wound complications or recurrence. MRI study indicated that abdominal muscles were postoperatively well preserved. Although wound infections (6%) and seroma (9%) were frequent complications, there was no need for meshes to be removed in the follow-up., Conclusion: Open ventral herniorrhaphy with mesh is safe, effective and inexpensive. Small, recurrent hernias were infrequent and easy to re-operated on. Severe pain from the mesh was not common. Postoperative MRI study indicated no obvious damage of abdominal muscles after mesh placement.

Intrathoracic splenosis is a rare sequel of left thoracoabdominal injury. A case simulating esophageal leiomyoma is presented. As in most earlier cases, the diagnosis was established only at thoracotomy. As splenosis is asymptomatic and may have some beneficial immunologic effects, surgical removal is inadvisable. The 23 previously published cases and the possibility of nonsurgical diagnosis are discussed.
