“…Changes in the hip joint's structure can also precipitate premature osteoarthritis, which causes pain and limits mobility. Moreover, alterations in the hip joint can limit its range of motion, and leg length disparities can cause additional complications [10][11] . Importantly, the chronic nature of these effects can also result in psychosocial difficulties, necessitating a comprehensive, holistic approach to care 12 .…”

Background: Perthes disease is a form of juvenile idiopathic osteonecrosis characterized by temporary bone mortality due to inadequate blood supply to the femoral head. Objectives: This cross-sectional study aimed to evaluate the treatment outcomes and sequelae of Perthes Disease and to identify the most effective treatment modalities for managing its sequelae. Methods: The research enrolled 59 Perthes Disease patients who had completed treatment at our institution between 2021 and 2022. The information pertaining to demographic characteristics, clinical presentations, radiological findings, specific treatments administered, and follow-up records were collected. Pain levels and hip functionality were secondary outcome measures. The Harris Hip Score (HHS) was used to assess the primary outcome of quality of life. Practical Implication: The practical implications for treating the sequelae of Perthes disease include early detection, a multidisciplinary approach, conservative management, surgical interventions when necessary, rehabilitation and physical therapy, long-term monitoring, and patient and family education. Timely diagnosis, collaboration among healthcare professionals, tailored treatment plans, and regular follow-up are important for optimizing outcomes and managing the condition effectively. Results: The average age of the study population was 4.76+1.10 years, with a higher proportion of males. Left-sided (59.32%) participation was more prevalent than right-sided (37.28%) participation (p<0.05). The disease's duration differed between patients. The majority of participants exhibited clinical symptoms such as hip or groin pain, limping, restricted hip movement, and deformities. The most prevalent treatment modality (p<0.05) was physical therapy (52.54%), followed by orthotic devices (30.50%) and surgical interventions (16.94%). Surgical procedures employed both extra-articular (70%) and intra-articular techniques (10%) (p<0.05). Conclusion: Multimodal, patient-specific approach is essential for managing Perthes disease sequelae. Physical therapy was the primary modality of care, while surgical interventions were employed selectively. Significant improvements were observed in pain reduction, functional outcomes, deformity correction, and ROM as a result of the treatment. These findings provided important insights into the management of Perthes disease and highlighted the need for individualized treatment strategies to achieve optimal patient outcomes.

Purpose Factors affecting direction of pelvic obliquity (PO) in dysplastic hip osteoarthritis (DHOA) remains unclear. This retrospective cohort study evaluates morphological characteristics, spinal alignment, and hip function in patients with unilateral DHOA. Methods Between 2018 and 2022, 104 patients with unilateral DHA were enrolled. Patients were categorized into flat PO (F-PO group; PO < 2°), affected side PO (A-PO group; PO downward by ≥ 2°), and unaffected side PO (U-PO group; PO upward by ≥ 2°). Demographics, radiographic hip and lower limb parameters, spinal parameters, and functional scores were compared between the groups. Results There were 39, 44, and 21 patients in the F-PO, A-PO, and U-PO group, respectively. The subluxation percentage of Crowe classification showed a significant difference among the three groups. The femoral head lateralization distance was significantly greater in the U-PO group than in the F-PO and A-PO groups. Furthermore, the hip adduction angle was significantly lower in the A-PO group than in the F-PO and U-PO groups. The lumbar scoliosis angle was significantly different between the groups. In multivariate analysis, hip adduction angle was extracted as an independent factor associated with the A-PO. Age, subluxation percentage, and hip adduction angle were identified as independent factors associated with the U-PO. Harris hip score was significantly poorer in U-PO group than in F-PO group. Conclusions Hip adduction angle influenced A-PO, while age, subluxation percentage, and hip adduction angle influenced U-PO; lumbar scoliosis angle was associated with PO direction. U-PO patients had poorer functional scores, indicating the impact of hip contracture and subluxation on PO direction in DHOA.
