BACKGROUND:Lithium chloridecan promote the proliferation and osteogenic capacity of bone marrow mesenchymal stem cels in the necrotic region after avascular necrosis of the femoral head, which has become an issue of concern. OBJECTIVE:To compare the advantages and disadvantages of bone marrow stem cel transplantation combined with lithium chloride in the treatment of rabbit femoral head necrosis. METHODS: Passage 2 bone marrow mesenchymal stem cels from 1-week-old New Zealand rabbits were cultured in 0, 5, 10, 20, 40 mmol/L lithium chloride. Forty-eight healthy adult New Zealand rabbits were selected to make femoral head necrosis models in the right femoral head using liquid nitrogen freezing method and then randomized into four groups: model group with no implantation; lithium chloride group given lithium chloride treatment at 3 days after modeling; cel transplantation group given gelatin sponge implantation and bone marrow mesenchymal stem cel suspension injection into the femoral head after modeling; combined group given bone marrow mesenchymal stem cel suspension injection and lithium chloride treatment. Intraperitoneal injection of lithium chloride (45.2 mg/kg) was given daily beginning at the postoperative 3rdday, and the treatment duration was 4 weeks. RESULTS AND CONCLUSION:Lithium chloride at 10 mmol/L had the maximum effect on the proliferation of rabbit bone marrow mesenchymal stem cels, and if the concentration of lithium chloride was > 10 mmol/L, the promotion role of lithium chloride began to decline. After combined treatment, the morphology of the femoral head was restored a little, with increased bone density and thickened trabecular bone; the level of β-catenin in the femoral head was significantly increased in the combined group compared with the cel transplantation group or the lithium chloride group. These findings show that bone marrow stem cel transplantation combined with lithium chloride treatment can promote the recovery from femoral head necrosis by increasing bone mass of the trabecular bone and bone density of the femoral head in the necrotic region.

BACKGROUND:Studies have shown that anterolateral approach for repairing the hip joint capsule has great effects on dislocation after hip replacement, but it remains unclear at present. OBJECTIVE: To study the impact of anterolateral approach for repairing the hip joint capsule on dislocation after artificial hip joint replacement. METHODS: 480 patients, who received artificial hip joint replacement in the First People’s Hospital of Qinzhou from January 2010 to January 2014, were enroled in this study. They were divided into the control group (January 2010 to January 2012) and the observation group (February 2012 to January 2014) according to the order of their admission, each of 240 cases. The control group was subdivided into the total hip replacement group (A1 group) and the femoral head replacement group (A2 group), each of 120 cases; and the observation group was also subdivided into the total hip replacement group (B1group) and the femoral head replacement group (B2 group), each of 120 cases. A1group and A2 group were subjected to artificial hip joint replacementvia anterolateral approach. B1 group and B2 group were subjected to artificial hip joint replacementvia anterolateral approach and the repair of the joint capsule. The postoperative early dislocation rate was analyzed in patients of A1 group and B1 group. Postoperative early dislocation rate was analyzed in patients of A2 group and B2 group. RESULTS AND CONCLUSION: The rate of early postoperative dislocation was 6.7% in A1 group, and 0.8% in the B1 group. The rate of early postoperative dislocation was significantly higher in the A1group than in the B1 group (P < 0.05). The rate of early postoperative dislocation was 3.3% in the A2 group and 0.8% in the B2 group. No significant difference was found between the A2 and B2 groups (P > 0.05). Results showed that anterolateral approach in repairing the hip joint capsule can effectively reduce the incidence of postoperative dislocation after the total hip replacement, but does not obviously impact postoperative dislocation.
