Ultrasound characteristics of gouty tophi in the olecranon bursa and evaluation of their reproducibility

Objectives

To describe the ultrasound characteristics of gouty tophi in the olecranon bursa and to evaluate their reproducibility.

Methods

A prospective study of the ultrasound features of 35 sites of tophi nodulations in the elbows of 31 men (mean 54.6 years). The findings were evaluated dynamically following pre-established standards. The static images were evaluated by another radiologist and were reviewed by the first examiner.

Results

The most frequent characteristics of tophi are: hyperechogenicity (91.7%), poorly defined contours (88.6%), multiple grouped nodules (85.6%) and heterogeneity (68.6%). Intra-observer agreement is almost perfect for echogenicity (K = 1.0), moderate for the involvement of the olecranon bursa (K = 0.47) and fair for other characteristics. Inter-observer agreement is substantial for the echogenicity (K = 0.65), fair for the echotexture (K = 0.27) and the presence of a perilesional hypoechoic halo (K = 0.34) and slight for other characteristics.

Conclusions

The most frequent characteristic of tophi is hyperechogenicity. The intra-observer and inter-observer concordance for echogenicity are almost perfect and substantial, respectively. Knowledge of characteristics of the tophi in the elbow and their intra and inter-observer reproducibility may assist in establishing parameters for monitoring treatment and setting up criteria for differential diagnosis of processes involving the olecraneon bursa.     

Sodium Tetradecyl Sulphate Sclerotherapy for Lateral Malleolar Bursitis of the Ankle

BackgroundThe aim of this study was to evaluate clinical outcomes of sodium tetradecyl sulphate (STS) sclerotherapy for conservative treatment of lateral malleolar bursitis of the ankle.MethodsWe reviewed data from 20 consecutive patients (20 ankles) who underwent STS sclerotherapy between August 2018 and June 2019. After aspiration of fluid from the lateral malleolar bursal sac, 2 mL (20 mg) STS was injected into the sac. Clinical outcomes and side effects and complications were evaluated at 2 weeks, 3 months, 1 year, and 2 years after sclerotherapy. Responses to treatment were assessed according to degree of fluctuation, shrinkage of the bursal sac, and soft-tissue swelling. The 36-item short form survey (SF-36) was completed for each patient before and after therapy.ResultsComplete response was observed in 17 patients (85%), and partial response was observed in 3 patients (15%) after STS sclerotherapy. SF-36 physical component scores improved from 62.2 (interquartile range, 5.2) before therapy to 70.0 (interquartile range, 7.9) at last follow-up (p < 0.05). One patient (5%) experienced transient hyperpigmentation at the injection site. No major complications occurred.ConclusionsSTS sclerotherapy was an effective and safe treatment for patients with lateral malleolar bursitis of the ankle.

Ultrasonographic assessment of pes anserinus tendon and pes anserinus tendinitis bursitis syndrome in patients with knee osteoarthritis

Abstract

Objective. The aim of this study was to assess the ultrasonographic (US) findings of pes anserinus tendon and bursa in patients with knee osteoarthritis (OA) with or without clinical pes anserinus tendinitis bursitis syndrome (PATBS).

Methods. A total of 157 female patients with the diagnosis of knee OA on both knees (314 knees), and 30 age, and body mass index- matched healthy female controls without knee pain (60 knees), were included in the study. PATBS was clinically diagnosed. US evaluation parameters were the measurement of the thickness of pes anserinus tendon insertion region (PA) and examination of the morphologic intratendinous PA tissue characteristics and pes anserinus bursitis (PAB). Radiographic knee osteoarthritis graded I-IV according to Kellgren and Lawrence (KL) for each knee was recorded. Pain and functional status were assessed by the Visual Analog Scale (VAS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC).

Results. There were 183 PATBS (58.3%) clinical diagnoses among the 314 knees with OA. The mean thickness of PA in the patients with knee OA graded 1,2,3,4 with/without PATBS was significantly greater than the controls (p = 0.001). The mean thickness of PA in knees with OA KL graded 3 and 4 with/without PATBS, was greater than knees with OA KL graded 1 and 2 with/without PATBS (p < 0,05) (except knee OA KL graded 2 with PATBS versus knee OA KL graded 4 without PATBS).The knee OA KL graded 1,2,3,4 with PATBS had significantly more PAB and less loss of normal fibrillar echotexture of PA compared to controls and knees with OA KL graded 1,2,3,4 without PATBS (p < 0.05). The VAS scores of knees with OA KL graded 3, 4 with PATBS were significantly greater than those of knees with OA KL graded 3,4 without PATBS (p < 0.05). PA thickness was significantly associated with the KL grade (r: 0.336, p:0.001) and PATBS (r: 0.371, p < 0.001).

Conclusion. It is concluded that the mean thickness of PA in knees with OA with/without PATBS was significantly greater than the controls. The mean thickness of PA in knees with OA, KL graded 3 and 4 with/without PATBS, was greater than in knees with OA KL graded 1 and 2 with/without PATBS. The knee OA with PATBS had significantly more PAB, less loss of normal fibrillar echotexture of PA, and higher VAS scores compared to the knees with OA without PATBS. US can serve as a useful diagnostic tool for detection of PATBS in knee OA.     

Knee bursitis: a sonographic evaluation

Objective

To evaluate the use of ultrasound for the diagnosis of knee bursitis.

Materials and methods

One-hundred and fifty-eight patients who, from May 2013 to May 2014, had an ultrasound examination of the knee and magnetic resonance imaging (MRI) of the knee during the following month were eligible for the study. The exams were reviewed by two musculoskeletal radiologists with 20 years of experience.

Results

Of these patients, 15 (7 men, 8 women) had bursitis, while 143 (76 men, 67 women) had no bursitis. In evaluating knee bursitis, US, when compared to MRI, correctly identified 13 out of 15 cases of bursitis, showing a sensitivity of 86.67 %, specificity 100 %, and K index of 0.92. Particularly in the suprapatellar bursa, ultrasound showed bursitis in 5 cases versus 7 by MRI (sensitivity of 71.4 %, specificity of 100 %, and K index of 0.82).

Conclusion

Ultrasound can be used as a valuable tool for the evaluation of bursitis of the superficial bursae in patients who cannot undergo MRI.     

针刺为主治疗肩周炎临床疗效观察

根据祖国传统医学,肩周炎属中医经筋病,病因是中老年人气血不足、并常因劳损或感受风寒等诱因而发病,疼痛常有固定痛点,疼痛尤甚,遇冷则痛剧,有得温则痛缓解等特点,严重者影响日常工作和生活.而现代医学的有关理论及朱汉章数十年临床观察研究认为：肩周炎的根本病因是泌失调所致.所以治疗中采用疏经脉、行气活血,调节内分泌平衡为原则,临床中采用多向透刺剥离法可松解粘连、解除痉挛、行气活血,沟通经穴和非经穴,并在组织内,机械能转化为热能,此热能使小血管扩张,小血管扩张,加强了局部的肌肉组织平衡,同时起到补气活血的作用.中药外敷起到疏通经脉,活血化瘀,使局部肌肉组织得到充足的营养.治疗中观察到二者结合使用,起到协同和互补作用提高治疗效果,缩短治疗时间.     

Greater trochanteric pain syndrome: epidemiology and associated factors

OBJECTIVES: To describe the prevalence of greater trochanteric pain syndrome (GTPS); to determine whether GTPS is associated with iliotibial band (ITB) tenderness, knee osteoarthritis (OA), body mass index (BMI), or low back pain (LBP); and to assess whether GTPS is associated with reduced hip internal rotation, physical activity, and mobility. DESIGN: Cross-sectional, population-based study. SETTING: Multicenter observational study. PARTICIPANTS: Community-dwelling adults (N=3026) ages 50 to 79 years. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Greater trochanteric tenderness to palpation in subjects with complaints of hip pain and no signs of hip OA or generalized myofascial tenderness. RESULTS: The prevalence of unilateral and bilateral GTPS was 15.0% and 8.5% in women and 6.6% and 1.9% men. Odds ratio (OR) for women was 3.37 (95% confidence interval [CI], 2.67-4.25), but age and race were not significantly associated with GTPS. In a multivariate model, adjusting for age, sex, ITB tenderness, ipsilateral and contralateral knee OA, BMI, and LBP, ITB tenderness (OR=1.72; 95% CI, 1.34-2.19), knee OA ipsilaterally (OR=3.47; 95% CI, 2.72-4.42) and contralaterally (OR=1.74; 95% CI, 1.32-2.28), and LBP (OR=2.79; 95% CI, 2.22-3.50) were positively related to GTPS. In this complete model, BMI was not associated with GTPS (OR=1.10; 95% CI, 0.80-1.52 when comparing >or=30 with <25kg/m(2)). Hip internal rotation range of motion did not differ based on GTPS status. After multivariate adjustment, GTPS did not alter physical activity score, but bilateal GTPS was significantly associated with a higher 20-meter walk time and chair stand time. CONCLUSIONS: The higher prevalence of GTPS in women and in adults with ITB pain or knee OA indicates that altered lower-limb biomechanics may be related to GTPS. Slower functional performance in those with GTPS suggests that the study of targeted rehabilitation may be useful. A longitudinal study will be necessary to identify causal factors and outcomes of interventions.
