Clinical Results, Tonnis Classification, and Stulberg Classification in Patients With Legg-Calvé-Perthes Disease Underwent Containment Surgeries

Background and objectives: the treatment methods for legg-calvé-perthes disease (lcpd)patients with herring c involvement scores are divided into two categories: non-surgicaltreatments, including pain relief and physical therapy, braces or casts; and surgical treatments,including all types of femoral head containment surgeries. although many researchers agree withconservative treatment, some also declare that surgery can be effective in improving the clinicalresults of group c patients. this study’s goals include examining clinical results, osteoarthritisstatus based on tonnis classification, and stulberg deformity degree of patients with lcpd withherring c involvement scores, who underwent various types of containment surgery.methods: in this study, 18 patients (19 hips) diagnosed as herring group c involvement lcpdunderwent one type of containment surgery, including femoral varus osteotomy, femoral valgusosteotomy, salter osteotomy, ganz osteotomy, and triple innominate osteotomy. participantswho met the inclusion criteria were examined in terms of demographic-biometric information(age, follow-up period, gender, operated side, body mass index) and clinical-radiographicinformation, including range of motion, lower limb discrepancy (lld), limping, trendelenbergtest, tenderness, classification of osteoarthritis based on tonnis classification, merle d’aubigne-postel score, and stulberg classification.results: the mean patients’ current age and age at surgery were 13.9±3.3 and 8.3±2 years,respectively, and the mean follow-up period was 5.7±2.8 years. two hips belonged to onefemale patient (10.5%), and 18 hips belonged to 18 male patients (89.5%). the left side wasmore frequently involved (57.9%), and the mean body mass index was 21.3 kg/m2. in the postoperationclinical results examination, significant differences were observed in only 3 variables:range of motion in abduction (p<0.001), external rotation (p=0.042), and extension (p=0.037).tonnis osteoarthritis class also improved significantly after surgery (p=0.029). the mean post-opmerle score of patients was 17.3. regarding post-op stulberg class, the highest frequency wasrelated to class 2 with 42.1% (8 people) and no patient was placed in class 5.conclusion: in addition to improving the range of motion, surgery reduces tonnis osteoarthritisclassification and stulberg grade in lcpd herring c patients.
