Arthroscopic Treatment of Synovial Osteochondromatosis of the Hip

Abstract

Objective: The objective of this study is to show the results achieved in the treatment of hip osteochondromatosis by arthroscopy. Methods: Six patients submitted to hip arthroscopy for synovial osteochondromatosis have been assessed for pre- and postoperative function and pain. The time of preoperative complaint ranged from nine to 48 months, in an average of 28.2 months and the follow-up ranged from eight to 25 months (mean: 17.1 months). Mean age was 45.1 years, with four female patients (66.6%) and the right side affected in five cases (83.3%). Results: Concerning the results according to Byrd-modified Harris' criteria, the mean score evolved from 54.1 to 90.4, and the mean score on the face expressions scale for pain assessment ranged from 1.7 to 5.1. Conclusion: arthroscopy is a good alternative for hip osteochondromatosis treatment, although longer follow-up times are required to strictly stating this. The results found so far are encouraging, constituting a littleinvasive procedure allowing good recovery.

Synovial chondromatosis of the hip, a case report and literature review

“…The search resulted in 178 articles, of which 13 studies including 290 patients could be included in the review.3, [8][9][10][11][12][13][14][15][16][17][18][19] Two studies did not report outcomes, but did analyse the extra-articular extent of synovial chondromatosis. 3,14 General patient characteristics can be found in Table 1.…”

“…In cases in which arthroscopy was performed a mean recurrence rate of 23% was reported. 8,[10][11][12][13][14][15][16][17][18][19] No recurrence was reported after arthrotomy in combination with surgical dislocation of the hip. 9-12,15,17-20 , 21 .…”

“…Type of treatment was not related to postoperative Harris Hip scores (Table 1). [8][9][10][11]13,15,17,19 Seven studies described whether patients presented with extra-articular SC localisation, in 41 out of 103 patients extra-articular localisation of SC was reported. 3,8,9,13,15,18,20 Robinson and colleagues analysed the extra-articular localisation SC around the hip and reported that SC either spreads into the iliopsoas bursa or the bursa of the obturator externus.…”

Current possibilities for hip arthroplasty

“…Hip arthroscopy is an excellent tool for removing free bodies from the hip joints, which could be bone or osteochondral fragments resulting from hip dislocation, firearm projectiles, synovial chondromatosis, broken guidewires or other types of foreign bodies of joints, 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 thus enabling effective and complete removal of the free bodies, synovectomy and rapid rehabilitation 64 , 65 , 66 , 67 , 68 , 69 ( Fig. 2 ).…”

“…It is also an option for treating pigmented villonodular synovitis, synovial chondromatosis and osteoid osteoma of the hip. 64 , 70 , 71 , 72 , 73 …”
