Rare and uncommon diseases of the hip: arthroscopic treatment.

Aim Uncommon and rare hip diseases are sources of pain and functional limitation particularly in young patients. Some of these conditions may be nowadays treated by arthroscopy due to the expertise and technical tips that high-volume hip arthroscopies have achieved during the last decades ensuring a wider range of indications for such a procedure. The aim of this study was to evaluate clinical results of arthroscopy in treating uncommon or rare diseases of the hip at a single Institution. Methods Thirteen patients affected by several types of diseases were treated by a hip arthroscopy and retrospectively evaluated. All patients were operated by the same surgeon, instrumentation and technique, but postoperative rehabilitative protocol was tailored on each patient and his disease. Each patient underwent a specific imaging, consisting of dedicated x-rays and arthro-MRI. Modified Harris Hip score (mHHS) and Non-Arthritic Hip score (NAHS) were used before and after surgery to clinically assess the outcome. Results All patients reported satisfaction, pain relief, and a good functional recovery at the latest follow-up visit. Only one patient affected by chondromatosis reported a recurrence of synovitis and needed a further arthroscopy 25 months after the index operation. No complications were reported at the latest follow-up. The NAHS and mHHS showed good improvements and all patients referred high satisfaction. Conclusion Hip arthroscopy performed by expert and high-volume surgeons may ensure good results in patients affected by uncommon and rare hip diseases.

Comparison of cardiovascular screening guidelines for middle-aged/older adults.

PURPOSE: Although both European (EACPR) and American (ACSM) Scientific Societies have devised cardiovascular protocols for the assessment of "middle-aged/older" individuals who are about to participate in sports or physical exercise, there are no data regarding the guidelines' sensitivity of these measures. The aim of this study was to compare the outcomes of different international screening protocols. METHODS: This observational cross-sectional study evaluated 525 subjects (80% males; median age 50 [35-85] years) seeking medical certification before participating in sports or regular exercise. The screening protocol consisted in completing a personal history profile, a physical examination, a resting ECG, a maximal exercise test, and, when required, additional instrumental evaluations. The effectiveness of the current EACPR as well as the former and new ACSM guidelines was thereby analyzed. RESULTS: The full screening protocol uncovered 100 previously undetected cardiovascular conditions (main pathologies detected: 21 coronary artery disease (CAD), 14 arterial hypertension, 38 complex arrhythmias). When the European guideline was used, 49% of these conditions went undetected, including 10 CAD. When the former American guideline was used, 29% (6 CAD) went undetected; when the recently updated edition was used, 50% including 11 CAD went undetected. CONCLUSION: The former ACSM guideline demonstrated a higher diagnostic sensitivity than the newer version and the EACPR guideline. Current screening protocols might be adapted for subjects performing high-intensity exercise due to their higher risk for cardiovascular and exercise-associated adverse events. The use of an incremental ECG-monitored maximal exercise test seems to improve these screening outcomes.
