RESUMO
BACKGROUND: Inpatient care in Germany has been subject to change since the introduction of the DRG-based payment system. There have been no publications on important differentiating factors such as the spectrum of care and the staffing situation in dermatology. METHODS: Health care analysis of 115 dermatology hospitals in October 2019 using a structured survey questionnaire. RESULTS: On average, the spectrum of care included 31.0 % general dermatology, 33.6 % surgical dermatology, 15.6 % oncology, and 10.1 % allergology. The clinics had an average of 14 full-time positions and 3 part-time positions (university clinics: 23/5, non-university clinics: 9/2). The mean nationwide proportion of women in the physician teams showed the following distribution: postgraduate physicians 73.3 %, senior physicians 53.0 %, directors 20.0 %. The applicant situation of senior physicians and specialists was assessed as predominantly poor, that of residents as predominantly good. Worse applicant situations were present in non-university hospitals and in rural areas. The satisfaction of the medical directors with the current conditions of inpatient care showed a variable assessment independent of university hospital and non-university hospital status. However, the threat to inpatient care was predominantly assessed as low (71.6 %). CONCLUSIONS: The overall situation of inpatient dermatological care can be classified as predominantly good. In addition, the majority of dermatology clinics provide a wide range of care with regard to the variety of indications. The general conditions, which in some cases are rated as inadequate, require further measures.

BACKGROUND: The objective of the study was to characterize the performance of German dermatology hospitals. METHODS: A structured survey questionnaire was sent out to all dermatology hospitals in October 2019 as part of a cross-sectional analysis based on health care research. RESULTS: Of the 115 hospitals, 95 (82.6 %) responded, including 34 (35.8 %) university hospitals (UC) and 61 (64.2 %) non-university hospitals (NUC), of which 78 % were urban (43 % UC, 57 % NUC) and 22 % rural (10 % UC, 90 % NUC). The dermatology departments comprised an average of 45 inpatient and 11 day-care beds (UC: 52/13, NUC: 40/9). An average of 2,302 inpatients were cared for in 2018 (UC: 2,874, NUC: 1,983), and the case mix index was 0.76 (UC: 0.74, NUC: 0.77, overall range: 0.40-0.96). Mean length of stay was 5.5 days for UC, relevantly lower than 2013 (5.9 days) and 2011 (7.1 days) data, and also significantly lower for NUC at 5.9 (2018) versus 5.1 days (2013). CONCLUSIONS: German dermatology hospitals continue to have a high volume of inpatient care, with a comparison of the last six years again showing a compression with shorter length of stay and higher occupancy density. Dermatological hospitals represent an essential pillar of dermatological care.

BACKGROUND: In Germany, skin diseases are mainly treated in the 115 dermatological hospitals. METHODS: Health care and health economic analysis of dermatological inpatient care and prediction of future care needs based on primary and secondary data. RESULTS: Outpatient and inpatient care for dermatologic treatment indications is predominantly provided by dermatology specialists. Inpatient treatment was provided for 833,491 cases in 2018, corresponding to 4.21 % of all inpatient cases (19,808,687). Most common treatment cases were: epithelial skin cancer (total 87,386, of which dermatology clinics 52,608), followed by melanoma (23,917/17,774), psoriasis (19,291/13,352), erysipelas (73,337/11,260), other dermatitis (12,671/10,842), atopic dermatitis (AD) (11,421/9,734), and herpes zoster (26,249/9,652). With an average length of stay of 5.69 days, dermatology hospitals were in the bottom third. The proportion of inpatient indications cared for in dermatology hospitals was highest for prurigo (95.2 %), pemphigus (94.9 %), parapsoriasis (94.6 %), pemphigoid (90.3 %), eczema other than AD (85.6 %), and AD (85.2 %). While the total number of inpatient treatment cases in Germany has increased by an average of 17.5 % between 2000 and 2018, this is the case for 26.6 % of skin diseases and over 150 % for individual ones. The projection of current to future inpatient care suggests a continued high demand for inpatient care by dermatology hospitals. CONCLUSION: Inpatient dermatological care will continue to be an indispensable component of qualified, socially necessary care in Germany.

OBJECTIVE: Patients suffering from peripheral arterial occlusive disease (PAOD) are a central target population for multidisciplinary vascular medicine. This study aimed to highlight trends in treatment patterns and comorbidities using up to date longitudinal patient related data from Germany. METHODS: This study is a retrospective health insurance claims data analysis of patients insured by the second largest health insurance provider in Germany, BARMER. All PAOD patient hospitalisations between 2008 and 2016 were included. The comorbidities were categorised with Elixhauser groups using WHO ICD-10 codes and summarised as the linear van Walraven score (vWS). A trend analysis of the comorbidities was performed after standardisation by age and sex. RESULTS: A total of 156 217 patients underwent 202 961 hospitalisations (49.4% for chronic limb threatening ischaemia in 2016) with PAOD during the study period. Although the estimated annual incidence of PAOD among the BARMER cohort decreased slightly (- 4.4%), an increase was observed in the prevalence of PAOD (+ 23.1%), number of hospitalisations (+ 25.1%), peripheral vascular interventions (PVI, + 61.1%), and disease related reimbursement costs (+ 31%) from 2008 to 2016. Meanwhile, the number of major amputations decreased (- 15.1%). The proportion of patients aged 71-80 years increased about +10% among PAOD patients and the mean vWS also increased by two points during the study period. Considerable increases were found in the rates of hypertension, renal failure, and hypothyroidism, whereas the rates of diabetes and congestive heart failure decreased over time. CONCLUSION: Increasing numbers of PVI performed on these ageing and sicker patients lead to rising costs but correlate with decreasing major amputation rates.

Background: Although epidemiological data suggest an association between periodontitis (PD) and peripheral arterial disease (PAD), it is currently unclear whether treatment of PD influences the severity of PAD. Patients and methods: Whether periodontal treatment is associated with PAD disease severity was examined by analysing health insurance claims data of patients insured by the German health insurance fund, BARMER, between January 1, 2012 and December 31, 2016. The presence of PAD was determined in individuals using International Classification of Diseases (ICD) 10th revision codes for intermittent claudication (IC) or chronic limb threatening ischaemia (CLTI). Treatment of PD was assessed by adequate ambulatory coding for non-surgical and surgical treatment of PD. Multivariate logistic regression analysis was performed to evaluate the association between PAD stages and periodontal treatment, adjusted for diabetes, age and sex. Results: The study cohort included 70,944 hospitalized patients with a diagnosis of symptomatic PAD (54.99 % women, 49.05 % IC). Among these patients, 3,567 (5.03 %) had received prior treatment for PD by supra- or sub-gingival debridement. PAD patients who had received periodontal treatment showed a lower proportion of CLTI (28.76 % among treated vs. 52.12 % among non-treated). Using multivariable regression methods, exhibiting a CLTI (vs. IC) was associated with not being treated for PD (Odds Ratio 1.97, 95 %-CI 1.83-2.13) after adjustment for age, gender, and diabetes. Conclusions: In this large-scale retrospective analysis of health insurance claims data comprising hospitalized symptomatic PAD patients, treatment of PD was associated with PAD disease severity independent of age, gender and diabetes. A potential benefit of periodontal treatment in relation to PAD will have to be determined in further prospective studies.

Background: Cancer as a concomitant condition in symptomatic peripheral arterial disease (PAD) patients could have an impact on further therapy and the long-term prognosis of these patients. Aim of this study was to investigate whether there is an increased incidence of cancer in PAD patients and to quantify the corresponding effect size. Materials and methods: Between January 1st, 2008 and December 31st, 2017, we analysed health insurance claims data from Germany's second-largest insurance fund, BARMER. Symptomatic PAD patients suffering from intermittent claudication (IC) or chronic limb-threatening ischaemia (CLTI) were stratified by gender at index treatment. PAD patients were then followed until an incident cancer diagnosis was recorded. To adjust for age and gender, standardized incidence ratios (SIR) were computed using the 2012 German standard population as reference. Results: 96,528 PAD patients (47% female, 44% IC, mean age 72 years) were included in the current study. When compared to the overall population, female and male PAD patients have a significantly increased risk of incident cancer of the lung (SIR 3.5 vs. 2.6), bladder (SIR 3.2 vs. 4.0), pancreas (SIR 1.4 vs. 1.6), and colon (SIR 1.3 vs. 1.3). During ten years of follow-up, some 7% of males and 4% of females developed lung cancer. For bladder, colon and pancreas cancer, the cumulative hazards were 1% vs. 3.2%, 2.2% vs. 2.8%, and 0.7% vs. 0.9%, respectively. Conclusions: Patients suffering from symptomatic PAD face a markedly higher risk for incident cancer in the long-term follow-up. The cancer risk increased continuously for certain types and PAD was strongly associated with cancer of the lung, bladder, pancreas, and colon. Taking these results into account, PAD patients could benefit from secondary and tertiary screening. These results also emphasize the impact of common risk factors such as tobacco smoke as target for health prevention.

Recently, health insurance claims have regained the attention of the scientific community as a source of real-world evidence in health care research and quality improvement. To date, very few studies are available which investigate the validity of health insurance claims; these may be affected by bias from several sources, such as possible upcoding of co-morbidities and complications for reimbursement advantages. The IDOMENEO study investigates the inpatient treatment of peripheral arterial disease (PAD) comprehensively using various data sources with a consortium involving experts from health care research and data privacy, a large health insurance fund, biostatisticians, jurists, and computer scientists. Prospective registry data were collected from 30-40 vascular centres in Germany using the GermanVasc registry. In addition, health insurance claims data were prospectively collected from BARMER, the second largest health insurance fund in Germany. The consortium is currently developing a data privacy compliant method of health insurance claims data validation, the methodological foundations of which are described here.

BACKGROUND: Assessing liver fibrosis in patients after liver transplantation is still largely dependent on liver biopsy. Especially in children, noninvasive methods are of utmost importance. We evaluated tissue inhibitor of metalloproteinase 1 (TIMP1) and AST-to-Platelet Ratio Index (APRI) and their potential as serum biomarkers to predict liver allograft fibrosis (LAF) in a pediatric cohort. METHODS: In this retrospective, observational study, we analyzed 91 protocol liver biopsy specimens from 73 children after pediatric liver transplantation (PLT) and compared histological stage of liver fibrosis using LAF Score (LAFSc) and Ishak Score (IshakSc) to TIMP1-serum concentration and APRI using ROC analysis. RESULTS: In our cohort, TIMP1 and APRI reliably predict LAF. Depending on the histological scoring system, cutoff values for TIMP1 were 328 ng/mL (IshakSc ≥ IV) and 351 ng/mL (LAFSc ≥ 5) with AUC of 0.86 and 0.98. The cutoff for APRI was 0.8 with AUC of 0.87 (IshakSc ≥ IV) and 0.94 (LAFSc ≥ 5). Using LAFSc, TIMP1 and APRI showed excellent diagnostic accuracy to detect severe LAF (LAFSc ≥ 5) with PPV of ≥ 90% and NPV of 100%. CONCLUSION: TIMP1 and APRI are accurate biomarkers to predict severe LAF in children. The use of TIMP1 and APRI will not replace but complement liver biopsies after PLT to further improve our understanding of each individual patient.

OBJECTIVES: This systematic review aimed to identify evidence based quality indicators for invasive revascularisation of symptomatic peripheral arterial occlusive disease (PAOD). METHODS: A systematic search of clinical practice guidelines, consensus statements, systematic reviews, and meta-analyses reporting quality indicators in patients undergoing invasive open and percutaneous revascularisations for symptomatic PAOD (PROSPERO registration number: CRD42019116317) was performed. Furthermore, a grey literature search was conducted involving databases of professional vascular medical organisations. The identified publications were screened independently by two reviewers for possible inclusion and full texts of potentially relevant records were independently evaluated for eligibility. Disagreement was resolved by discussion involving a third reviewer. RESULTS: From 685 articles initially identified, one systematic review and one consensus statement focusing on quality indicators were selected for inclusion in the review. From these sources, a total of three process quality indicators matched the search criteria: one on pharmacological intervention, another on smoking cessation, and a third on surveillance of lower extremity vein bypass grafts. The grey literature search revealed an additional 31 structure, process, and outcome quality indicators. CONCLUSIONS: This study revealed a lack of published evidence based quality indicators concerning invasive treatment for PAOD in the literature. An additional 31 indicators from the databases of professional societies and organisations have not been incorporated in prior guidelines. Interestingly, no indicator related to patient reported outcomes could be identified from either high quality sources or grey literature. Further research and harmonisation of different quality indicators is needed to enhance their evidence and subsequently improve patient centred decision making on invasive treatment.

BACKGROUND: Cartilage calcification (CC) is associated with osteoarthritis (OA) in weight-bearing joints, such as the hip and the knee. However, little is known about the impact of CC and degeneration on other weight-bearing joints, especially as it relates to the occurrence of OA in the ankles. The goal of this study is to analyse the prevalence of ankle joint cartilage calcification (AJ CC) and to determine its correlation with factors such as histological OA grade, age and BMI in the general population. METHODS: CC of the distal tibia and talus in 160 ankle joints obtained from 80 donors (mean age 62.4 years, 34 females, 46 males) was qualitatively and quantitatively analysed using high-resolution digital contact radiography (DCR). Correlations with factors, such as the joint's histological OA grade (OARSI score), donor's age and BMI, were investigated. RESULTS: The prevalence of AJ CC was 51.3% (95% CI [0.40, 0.63]), independent of gender (p = 0.18) and/or the joint's side (p = 0.82). CC of the distal tibia was detected in 35.0% (28/80) (95% CI [0.25, 0.47]) and talar CC in 47.5% (38/80) (95% CI [0.36, 0.59]) of all cases. Significant correlations were noted between the mean amount of tibial and talar CC (r = 0.59, p = 0.002), as well as between the mean amount of CC observed in one ankle joint with that of the contralateral side (r = 0.52, p = 0.02). Furthermore, although the amount of AJ CC observed in the distal tibia and talus correlated with the histological OA-grade of the joint (r = 0.70, p < 0.001 and r = 0.72, p < 0.001, respectively), no such correlation was seen in the general population with relation to age (p = 0.32 and p = 0.49) or BMI (p = 0.51 and p = 0.87). CONCLUSION: The prevalence of AJ CC in the general population is much higher than expected. The relationship between the amount of AJ CC and OA, independent of the donors' age and BMI, indicates that CC may play a causative role in the development of OA in ankles.

BACKGROUND: Atherosclerotic disease of the lower extremity arteries (PAD) remains a significant burden on global healthcare systems with increasing prevalence. Various guidelines on the diagnosis and treatment of patients with PAD are available but they often lack a sufficient evidence base for high-grade recommendations since randomized and controlled trials (RCT) remain rare or are frequently subject to conflicts of interest. This registry trial aims to evaluate the outcomes of catheter-based endovascular revascularisations vs. open-surgical endarterectomy vs. bypass surgery for symptomatic PAD on medical and patient-reported outcomes. METHODS AND DESIGN: The study is a prospective non-randomized multicentre registry trial including invasive revascularisations performed in 10 000 patients treated for symptomatic PAD at 30 to 40 German vascular centres. All patients matching the inclusion criteria are consecutively included for a recruitment period of six months (between May and December 2018) or until 10 000 patients have been included in the study registry. There are three follow-up measures at three, six, and 12 months. Automated completeness and plausibility checks as well as independent site visit monitoring will be performed to assure high internal and external validity of the study data. Study endpoints include relevant major cardiovascular and limb events and patient-reported outcomes from two Delphi studies with experts in vascular medicine and registry-based research. DISCUSSION: It remains unclear if results from RCT can reflect daily treatment practice. Furthermore, great costs and complexity make it challenging to accomplish high quality randomized trials in PAD treatment. Prospective registry-based studies to collect real-world evidence can help to overcome these limitations.

INTRODUCTION: Peripheral arterial disease (PAD) affects a continuously increasing number of people worldwide leading to more invasive treatments. Indication to perform invasive revascularisations usually arises from consensus-based recommendations of practice guidelines and from few randomized controlled trials where outcome measures focus mainly on risk factors associated with mortality and morbidity. To date, no broad consensual agreement of experts on valid indicators of outcome quality exists for PAD. METHODS: A literature review was conducted to collect indicators of outcome quality from studies of PAD. The Delphi technique was used to achieve a consensual agreement on a set of core indicators. The expert panel of the two-round Delphi approach was formed by leading vascular specialists joining the IDOMENEO study, physician assistants, wound nurses, and patient representatives. Items were scored via a web-based anonymised electronic questionnaire using a five-point Likert-scale. RESULTS: Out of 40 invited experts 30 joined the panel and completed round one. Twenty-four experts completed the second and final round. Forty-three indicators of outcome quality were initially identified and validated by the panel. After two Delphi rounds, 12 indicators (27.9 %) achieved the limit of agreement for relevance and four (9.3 %) for practicability. Major adverse limb events (MALE), major amputation, and major re-intervention (or re-operation) were consented as both highly relevant and practicable. Additionally, major adverse cardiovascular events (MACE), myocardial infarction, stroke or transient ischaemic attack, all-cause death, all re-intervention (or re-operation), wound infection, vascular access-related major complication, walking distance, and Rutherford-classification were consented as highly relevant. Ankle-brachial-index was consented as highly practicable. CONCLUSIONS: This Delphi approach of vascular experts identified three indicators as highly relevant and clinically practicable to be recommended as indicators of outcome quality in invasive PAD treatment. Among others, these consented items may help in harmonising future studies and quality benchmarking increasing their comparability, validity, and efficiency.

BACKGROUND: Hyaline cartilage calcification (CC) is associated with osteoarthritis (OA) in hip and knee joints. The first metatarsophalangeal joint (1stMTPJ) is frequently affected by OA, but it is unclear if CC occurs in the 1stMTPJ. The aim of the present study was to analyze the prevalence of CC of the 1stMTPJ in the general population by high-resolution digital contact radiography (DCR) and to determine its association with histological OA severity, age and body mass index (BMI). METHODS: 168 metatarsal heads of 84 donors (n = 47 male, n = 37 female; mean age 62.73 years, SD ±18.8, range 20-93) were analyzed by DCR for the presence of CC. Histological OA grade (hOA) by OARSI was analyzed in the central load-bearing zone of the first metatarsal head (1st MH). Structural equation modeling (SEM) was performed to analyze the interrelationship between CC, hOA, age and BMI. RESULTS: The prevalence of CC of 1stMH was 48.8 % (41/84) (95 %-CI [37.7 %, 60.0 %]), independent of the affected side (p = 0.42), gender (p = 0.41) and BMI (p = 0.51). The mean amount of CC of one MH correlated significantly with that of the contralateral side (rs = 0.4, 95 %-CI [0.26, 0.52], p < 0.001). The mean amount of CC (in % of total cartilage area) of the MH correlated significantly with the severity of hOA (rs = 0.51, 95 %-CI [0.32, 0.65], p < 0.001). SEM revealed significant associations between CC and hOA (r = 0.74, p < 0.001) and between hOA and age (ß = 0.62, p = 0.001), but not between CC and age (p = 0.15). There was no significant influence of BMI on either CC (p = 0.37) or hOA (p = 0.16). CONCLUSION: The observation that CC of the 1stMH is significantly associated with the severity of OA but independent of age and BMI, suggests an intimate relationship between CC and the pathogenesis of OA, the exact nature of which will have to be explored by future studies.

Aim of the study was to characterise the association between screening, prevalence and mortality of skin cancer in Germany considering the spatial distribution. The study included the total set of outpatient data of all statutory health insured people and cause-of-death statistics in Germany between 2011-2015 on county level. To identify regions with high/low screening, prevalence and mortality rates, probability maps were calculated. Scenarios were developed based on the research questions. These were used to identify regions that share both high/low rates of screening, prevalence and mortality. Regression analyses were used to characterise these regions, taking into account sociodemographic characteristics. Significant regional variations in prevalence, screening and mortality in Germany were identified. Depending on the scenario, influences of sociodemographic conditions become apparent. For example, a lower income (p = 0.006) and poorer accessibility of the closest dermatologist (p = 0.03) predicted a lower prevalence of and fewer screenings for skin cancer. In regions with low screening and high mortality, significant (p = 0.03) associations with the educational status of the population were also found. The study identified the first spatial associations between screening, prevalence and mortality of skin cancer in Germany. The results indicate that regional population-related characteristics (e.g., sociodemographic characteristics) play an important role in explaining the associations and should be given more weight in further studies. However, further studies, particularly on the spatial variation of skin cancer mortality, are still necessary.

BACKGROUND: Canavan disease (CD, MIM # 271900) is a rare and devastating leukodystrophy of early childhood. To identify clinical features that could serve as endpoints for treatment trials, the clinical course of CD was studied retrospectively and prospectively in 23 CD patients. Results were compared with data of CD patients reported in three prior large series. Kaplan Meier survival analysis including log rank test was performed for pooled data of 82 CD patients (study cohort and literature patients). RESULTS: Onset of symptoms was between 0 and 6 months. Psychomotor development of patients was limited to abilities that are usually gained within the first year of life. Macrocephaly became apparent between 4 and 18 months of age. Seizure frequency was highest towards the end of the first decade. Ethnic background was more diverse than in studies previously reported. A CD severity score with assessment of 11 symptoms and abilities was developed. CONCLUSIONS: Early hallmarks of CD are severe psychomotor disability and macrocephaly that develop within the first 18 months of life. While rare in the first year of life, seizures increase in frequency over time in most patients. CD occurs more frequently outside Ashkenazi Jewish communities than previously reported. Concordance of phenotypes between siblings but not patients with identical ASPA mutations suggest the influence of yet unknown modifiers. A CD severity score may allow for assessment of CD disease severity both retrospectively and prospectively.

Importance: Costal cartilage calcification (CCC) of the cartilage graft, commonly used in reconstruction of nasal/auricular deformities, can cause poor surgical outcome, but structural and quantitative analyses are lacking. Objective: To compare the prevalence, amount, and structural pattern of CCC from individuals by gender and age, as measured by digital contact radiography. Design, Setting, and Participants: This is a cross-sectional cadaveric study (n = 92) of the seventh rib cartilage. CCC prevalence/amount/structural pattern (central [c]/peripheral [p]/diffuse [d]) was analyzed within three age groups: I (<40 years), II (40-70 years), and III (>70 years). Main Outcomes and Measures: Qualitative and quantitative CCC analyses were set in relation to gender/structural pattern/age. Results: CCC prevalence was gender independent (96.7%) and occurred in c/p/d: 12.4%/22.4%/65.2%. Structural CCC pattern differed between age groups (I: 80%; c/p/d: 26.7%/46.6%/6.7%; II: 100%; c/p/d: 18.0%/30.8%/51.2%; III: 100%; p/d: 2.6%/97.4%). The mean CCC amount (9.1%) was gender independent and showed a significant correlation with age (p = 0.001). The mean amount showed a significant difference between the structural pattern [d/p: 3.3 times higher (p = 0.006), d/c: 7.7 times higher (p < 0.001)] and age groups (I/II/III: 6.4/8.5%/10.9%), whereby the amount was higher in groups II (factor: 7.4; p < 0.001) and III (factor: 16.5; p < 0.001) compared with group I. Conclusions: These data show an age-/gender-independent high CCC prevalence in the general population (96.7%). CCC already occurred in young donors (<40 years) with a not negligible amount (6.4%). CCC increased with age and structural analysis showed a gender-/age-specific pattern, whereby males were prone to peripheral/females to central CCC. Diffuse CCC was observed as an age-independent sign for high CCC levels.
RESUMO
The acetabular labrum of the hip (ALH) is recognized as a clinically important structure, but knowledge about the pathophysiology of this fibrocartilage is scarce. In this prospective study we determined the prevalence of ALH calcification in patients with end-stage osteoarthritis (OA) and analyzed the relationship of cartilage calcification (CC) with hip pain and clinical function. Cohort of 80 patients (70.2 ± 7.6years) with primary OA scheduled for total hip replacement. Harris Hip Score (HHS) was recorded preoperatively. Total ALH and femoral head (FH) were sampled intraoperatively. CC of the ALH and FH was analyzed by high-resolution digital contact radiography. Histological degeneration of the ALH (Krenn-Score) and FH (OARSI-Score) was determined. Multivariate linear regression model and partial correlation analyses were performed. The prevalence of cartilage calcification both in the ALH and FH was 100%, while the amount of CC in the ALH was 1.55 times higher than in the FH (p < 0.001). There was a significant inverse regression between the amount of calcification of both the ALH and the FH and preoperative HHS (ßALH = -2.1, p = 0.04), (ßFH = -2.9, p = 0.005), but pain was influenced only by ALH calcification (ßALH = -2.7, p = 0.008). Age-adjusted, there was a significant correlation between cartilage calcification and histological degeneration (ALH:rs = 0.53, p < 0.001/FH: rs = 0.30, p = 0.007). Fibrocartilage and articular cartilage calcification are inseparable pathological findings in end-stage osteoarthritis of the hip. Fibrocartilage calcification is associated with poor and painful hip function. CLINICAL SIGNIFICANCE: ALH fibrocartilage appears to be particularly prone to calcification, which may explain higher pain levels in individuals with a high degree of ALH calcification independent of age and histological degeneration. © 2017 Orthopaedic Research Society.
