Developmental dysplasia of the hip broadly includes inadequate development of the hip joint involving the acetabulum or proximal femur, or both. Although ultrasonographic studies in neonates have greatly lowered the frequency of neglected or operatively treated cases, its sensitivity is less than desired. Hip dysplasia without subluxation is commonly diagnosed incidentally and strongly related to degenerative arthritis in females after the 4th decade. Hip dysplasia with subluxation shows symptoms through various periods, depending on its severity, especially for women with onset during pregnancy. A complete physical examination and early treatment for neonates are extremely important for obtaining satisfactory outcomes. To avoid underdiagnosis and to serve appropriate treatment on time, the authors recommend examining any suspicious hips in infants under two years of age. The study will discuss the diagnosis and primary treatment of developmental dysplasia of the hip.

Objectives The purpose of this study is to report the effects of Korean medicine treatments including Chuna manual therapy, pharmacopuncture and acupuncture for two patients who have pain in hip joint diagnosed with avascular necrosis of the femoral head. Methods The treatment effect was evaluated with a numeric rating scale (NRS), range of motion (ROM), physical examination (Patrick test), and score of Harris hip score (HHS). Results After treatment, symptoms of the two patients such as hip joint pain and gait dysfunction were improved. The NRS decreased from 8 (right [Rt.]), 7 (left [Lt.]) to 4 (Rt.), 3 (Lt.) in case 1 and from 9 to 2 in case 2. Also the patients showed improvement in ROM and score of HHS increased from 55.5 to 88.5 in case 1 and from 63.5 to 85.5 in case 2. In addition, positive Patrick test improved to negative. Conclusions Korean medicine treatments including Chuna manual therapy, pharmacopuncture and acupuncture can be effective in relieving pain and recovering the fucnction of hip joint associated with avascular necrosis of the femoral head, even when surgery is recommended. Although further study such as controlled studies is needed.

Objectives This paper is an analysis of domestic and foreign trends for the Korean medical treatment of avascular necrosis of the femoral head. Methods Domestic and foreign databases were searched and analyzed for Korean medical treatment interventions, research types, and treatment effects for avascular necrosis of the femoral head. Results There were 10 case reports in Korea, 2 case reports and 3 randomized controlled studies abroad. A total of 12 treatment interventions were used, and the types include acupuncture, herbal medicine, phamacopunture, electroacupuncture, cupping, physical therapy, chuna, acupotomy, moxibustion, warm acupuncture, laser acupuncture, and motion style treatment. As for the evaluation index, visual analogue scale, range of motion and harris hip score were the most common with 7 cases each. Conclusions Through this study, it was possible to understand the trends of domestic and foreign research on the treatment of avascular necrosis of the femoral head with Korean medicine. However, due to the small number of literature and no randomized control studies in Korea, treatment evidence is insufficient. It is considered that further research is needed in the future.

Operative interventions for the management of osteonecrosis of the femoral head (ONFH) include core drilling, with or without vascularized fibular bone grafting. Nevertheless, their clinical results have not been consistently satisfactory. Recently, a new surgical procedure that incorporates cementation with polymethylmethacrylate (PMMA) after core drilling has been tried clinically. In this study, a biomechanical analysis using a finite element method(FEM) was undertaken to evaluate surgical methods and their underlying surgical parameter. Our finite element models included five types. They were (1) normal model (Type I), (2) necrotic model (Type II), (3) core decompressed model (Type III). (4) fibular bone grafted model (Type IV), and (5) cemented with PMMA model (Type V). The geometric dimensions of the femur were based on digitized CT-scan data of a normal person. Various physiological loading conditions and surgical penetration depths by the core were used as mechanical variables to study their biomechanical contributions in stress transfer within the femoral head region. In addition. the peak von Mises stress(PVMS) within the necrotic cancellous bone of the femoral head was obtained. The fibular bone grafted method and cementation method provided optimal stress transfer behaviors. Here. substantial increase in the low stress level was observed when the penetration depth was extended to 0mm and 5mm from the subchondral region. Moreover, significant decrease in PVMS due to surgery was observed in the fibular bone grafted method and the cementation method when the penetration depths were extended up to 0 and 5mm from the subchondral region. The drop in PVMS was greater during toe-off than during heel-strike (57% vs. 28% in Type IV and 49% vs. 22% in Type V). Both the vascularized fibular bone grafting method (Type IV) and the new PMMA technique (Type V) appear to be very effective in providing good stress transfer and reducing the peak Von-Mises stress within the necrotic region. Overall results show that fibular bone grafting and cementation methods are quite similar. In light of above results, the new cementation method appears to be a promising surgical alternative or the treatment of ONFH. The use of PMMA for the core can be less prone to surgical complication as opposed to preparation of fibular bone graft and can achieve more immediate fixation between the core and the surrounding region.

Purpose : To observe the patency of anastomosis site and the findings of circulation of grafted fibula in osteonecrosis of femoral head treated with vascularized fibular graft by use of digital subtraction angiography. Materials and Methods : 17 cases of 11 patients who underwent vascularized fibula graft for osteonecrosis of femoral head. We performed digital subtraction angiography(DSA) for them at second week postoperatively in 12 cases, at sixth week in 1 case, at sixth month in 2 cases, at twelfth month in 1 case, and eighteenth month in 1 case which had been got DSA at second week before. We observe the patency of pedicle, and the circulation of grafted fibula such as periosteal and intraosseous vessels with time. Results : All cases except one which were thought failure of selective angiogram showed good passage of blood flow through anstomosed pedicle on DSA. We found the differences in appearance of circulation of grafted fibula with time. DSA at 2nd and 6th week postoperatively revealed both of periosteal and intraosseous vessels along the fibula and blood pooling at the tip of fibula. DSA at 6th month showed maintenance of periosteal and intraosseous vessels along the fibula but did not clearly reveal blood pooling at the tip of fibula. The findings of DSA at 12th and 18th month were similar each other. The periosteal vessels were not seen as the grafted fibular bone were incorporated into surrounding femoral bone but intraosseous vessels were still seen. Conclusion : It was thought that DSA could be used for evaluation of the status of pedicle including anastomsed site and vessels of grafted fibula with time. The periosteal vessels of fibula were decreased with time but intraosseous vessels were still seen until 18th month after vascularized fibula graft.

Objectives This study was conducted to investigate a randomized controlled trial study on the clinical treatment of herbal medicines for avascular necrosis of the femoral head. Methods By March 2022, the China National Knowledge Infrastructure (CNKI) was reviewed about randomized controlled trial studies on the herbal treatment of avascular necrosis of the femoral head through. The publication year, evaluation criteria, treatment period, treatment method and effectiveness were analyzed for articles published from 2017 to 2022. Results 16 articles were selected and 14 kinds of herbal medicines were used. In most studies, Western medical treatments such as injection therapy, oral drug administration, traction therapy and mid-frequency electric therapy were treated alone in the control group, and a combination of Western medical treatment and herbal treatment was administered to the experimental group. Conclusions In China, there have been many studies on herbal treatment for avascular necrosis of the femoral head. In Korea, more clinical studies on the herbal treatment of avascular necrosis of the femoral head are needed. This study will be helpful for future research in Korean medicine on avascular necrosis of the femoral head.

Operative procedures such as core drilling with and without fibular bone grafting have been recognized as the treatment methods for osteonecrosis of femoral head(ONFH) by delaying or preventing the collapse of the femoral head. In addition, core drilling with cementation using polymethylmethacrylate (PMMA) has been proposed recently as another surgical method. However, no definite treatment modality has been found yet while operative procedures remain controversial to many clinicians In this study, a finite element method(FEM) was employed to analyze and compare various surgical procedures of ONFH to provide a biomechanical insight. This study was based upon biomechanical findings which suggest stress concentration within the femoral head may facilitate the progression of the necrosis and eventual collapse. For this purpose, five anatomically relevant hip models were constructed in three dimensions : they were (1) intact(Type I), (2) necrotic(Type II), (3) core drilled only(Type III), (4) core drilled with fibular bone graft(Type IV), and (5) core drilled with cementation(Type V). Physiologically relevant loading were simulated. Resulting stresses were calculated. Our results showed that the volumetric percentage subjected to high stress in the necrotic cancellous region was greatest in the core drilled only model(Type III), followed by the necrotic(Type II), the bone graft (Type IV), and the cemented(Type V) models. Von Mises stresses at the tip of the graft(Type IV) was found to be twice more than those of cemented core(Type V) indicating the likelihood of the implant failure. In addition, stresses within the cemented core(Type V) were more evenly distributed and relatively lower than within the fibular bone graft(Type IV). In conclusion, our biomechanical analyses have demonstrated that the bone graft method(Type IV) and the cementation method(Type V) are both superior to the core decompression method(Type III) by reducing the high stress regions within the necrotic cancellous bone. Also it was found that the core region filled with PMMA(Type V) provides far smoother transfer of physiological load without causing the concentration of malignant stresses which may lead to the failure than with the fibular bone graft(Type IV). Therefore, considering the above results along with the degree of difficulties and risk of infection involved with preparation of the fibular bone graft, the cementation method appears to be a promising surgical treatment for the early stage of osteonecrosis of the femoral head.
