RESUMO
OBJECTIVE: The study aimed to explore the therapeutic effects of direct anterior internal fixation with Herbert screws on hip joint function and quality of life in patients with Pipkin type II femoral head fractures (FHF). METHODS: From Dec 2017 to Jul 2020, 68 patients with Pipkin type II FHF were received in our hospital and divided into two groups. The direct anterior internal fixation (DAIF) group including 34 cases were treated by direct anterior internal fixation with Herbert screws. The control group of 34 patients received modified internal fixation with Herbert screws via posterior superior iliac spine and ectogluteus. The duration time and blood loss in operation as well as the postoperative drainage volume, hospital stays and complications were observed. The comparison of pain degree, hip functions, and life quality between two groups was performed. RESULTS: All the patients were followed up, and the operative time, intraoperative blood loss, postoperative drainage and hospital stay of the DAIF group were all significantly lower than those in the control group, with (p < 0.05, respectively). The pain degree of the DAIF group was significantly lower than that of the control group 7, 15 and 30 days after the operation (p < 0.05, respectively). At 3, 6 and 9 months after the operation, the hip function recovery of the DAIF group was significantly better than control group (p < 0.05). There were no significant differences between the two groups in preoperative physiological function, physiological function, emotional role, physical pain, general health, vitality, social function and mental health (p > 0.05). Six months after the operation, the physiological function, physiological function, emotional role, physical pain, general health, vitality, social function and mental health of the DAIF group were significantly higher than those of the control group (p < 0.05). No postoperative complications occurred in both groups. CONCLUSION: The treatment of directly anterior internal fixation with Herbert screws is effective for Pipkin type II FHF, like improving the function of hip joint and quality of life in patients. The method is reliable and worth clinical use.

OBJECTIVE: Traumatic femoral neck fracture is a common disease that can be treated by hip arthroplasty, which is divided into hemiarthroplasty (HA) and total hip arthroplasty (THA). The difference between HA and THA are incompletely understood. The objective of this study was to investigate the effect of hip arthroplasty on hip function in patients with traumatic femoral neck fracture. METHODS: A total of 132 patients with traumatic femoral neck fracture admitted to our hospital from January 2019 to January 2021 were selected and divided into control group (HA group) and study group (THA group) with 66 cases in each group by random number table method. The duration of operation, intraoperative blood loss, postoperative drainage and length of hospital stay were compared between the two groups. The degree of pain before operation, 3 days after operation and 7 days after operation were observed, the hip joint function before operation, 6 months after operation and 12 months after operation was analyzed, and the occurrence of short-term and long-term complications was compared between the two groups. RESULT: Compared with the HA group, the operative time, intraoperative blood loss, postoperative drainage and hospital stay were higher in the THA group. The degree of pain in THA group was higher than that in HA group on 3 and 7 days after operation; At 6 and 12 months after surgery, the scores of pain, range of motion, joint function and deformity in the THA group were higher than those in the HA group with statistically significant. Compared with HA group, IGF-1 and Leptin in THA group were increased significantly, while inflammatory cytokines TNF-α was decreased in THA group. The total incidence of short-term and long-term complications was lower in THA group. CONCLUSION: Total hip arthroplasty can effectively restore hip joint function in patients with traumatic femoral neck fracture, with low incidence of short-term and long-term complications, high safety, and worthy of clinical application.

OBJECTIVE: The patellar inferior pole fracture is typically comminuted. Hence, achieving firm fixation and early activity is highly challenging. In this article, we employed the method of wire cerclage through a generated bone hole to reduce the fracture. Our objective was to compare the clinical efficacy of patellar concentrator alone with a combination of cerclage and patellar concentrator in the treatment of patellar inferior pole fracture. METHODS: We conducted a retrospective review of patients with patellar inferior pole fractures, who underwent patellar concentrator fixation only (the control group) or cerclage combined with patellar concentrator fixation (the experimental group), performed by a single surgeon, between July 2015 and October 2019. Our analysis included surgical indexes like7 aspects (fracture gap after operation, operation time, intra-operative blood loss, intra-operative number of C-arm fluoroscopies conducted, Insall-Salvati ratio calculated immediately after operation, initial range of motion on the 7th day after operation, and fracture healing time), as well as the Bostman score and complications recorded on 1-, 3-, 6-, and 12-month follow up post operation. RESULTS: A total of 94 patients with patellar inferior pole fracture and a minimum 1-year follow up were recruited. Following operation, the control group had 33 (71.74%) patients with a fracture gap of 0-2 mm and 13 (28.26%) patients with a fracture gap greater than 2 mm (P = 0.002). Conversely, the experimental group had 46 (95.83%) patients with a fracture gap of 0-2 mm and 2 (4.17%) patients with a fracture gap greater than 2 mm (P = 0.002). Compared to the control group, the experimental group did not experience enhanced operation time or intra-operative blood loss (P = 0.811, P = 0.823). The Insall-Salvati ratio and initial range of motion in the experimental group were larger than the control group (P = 0.037, P = 0.000). Alternately, the number of intra-operative C-arm fluoroscopies conducted and fracture healing time of the experimental group were considerably less than the control group (P = 0.003, P = 0.000). Moreover, at 1-, 3-, 6-, and 12-month follow ups after operation, the Bostman scores of the experimental group were remarkably higher than the control group (P < 0.05). At 12 months post operation, 23 cases (50%) were classified as excellent, 22 cases (47.83%) were good, and 1 case (2.17%) was poor in the control group (P = 0.005). In the meantime, in the experimental group, 38 cases (79.17%) were deemed as excellent and 10 cases (20.83%) were good (P = 0.005). Lastly, complications were detected in 3 cases (6.52%; 1 case of internal fixation loss, 2 cases of hematoma) within the control group, and in 1 case(2.08%; marginal wound necrosis) within the experimental group. There was no wound infection, implant discomfort, or broken fixation in either group. CONCLUSION: Managing the patellar inferior pole fracture with wire cerclage through a generated bone hole is both simple and effective. Moreover, an additional step of patellar concentrator fixation facilitates early functional exercise, with satisfactory clinical outcome.

BACKGROUND: The incidence of post-traumatic osteoarthritis (PTOA) after anterior cruciate ligament reconstruction (ACLR) is high, but there is still a lack of intra-operative preventive measures. This study aimed to evaluate the effect of different irrigating solutions continuous irrigation on intra-articular inflammation and cartilage degeneration. METHODS: 66 New Zealand rabbits were randomly divided into normal (N) group, no treatment (NT) group, sodium chloride (NaCl) group, magnesium sulfate (MgSO4) group, and calcium chloride (CaCl2) group. The right knee joint of the experimental group was utilized to construct the model of PTOA, and the left side was utilized as the normal control group. At different time points postoperatively, the blood concentration of hemoglobin and Mg2 + , the synovial fluid concentration of IL-1 ß, TNF-α, tartrate-resistant acid phosphatase-5b (TRAP-5b), and Type II Collagen, the gene expression of IL-1 ß and MMP-3, and the protein expression of TRPV5 and CaM were detected. Pearson's linear correlation was employed to identify the possible relationship between the expression of TRAP-5b and the expression of IL-1ß, IL-6, TNF-α, and Type II collagen. The hematoxylin and eosin staining (HE), Masson's trichrome staining, and Alcian blue staining were performed at postoperative 35 days. Osteoarthritis Scoring (OA score) comprised categories including Alcian blue staining, cartilage histology, the cellular density of cartilage, degree of cell disintegration, and formation of chondrocyte cluster were blindly scored by trained researchers at postoperative 35 days. RESULTS: There was no statistical difference (P > 0.05) in the hemoglobin concentration between different groups. The concentration of serum Mg2+ in the MgSO4 group was higher than that of the other three groups (P < 0.05) on the same day of operation, then gradually decreased. The expression of IL-1 ß, IL-6, and TRAP-5b in synovial fluid increased 5 days after the operation, decreased at 15 days, and then increased again with time in the NT group, NaCl group, and NT group and NaCl group. At 35 days after the operation, the expression of IL-1 ß, IL-6, TRAP-5b, and type II collagen in the MgSO4 group were lower than that in the other three groups (except group N) (P < 0.05).The correlation analysis results showed that the TRAP-5b levels correlated positively with IL-1 ß, IL-6, TNF-α, and type II collagen concentrations. The histological examination revealed that the surface smoothness of cartilage, the morphology of chondrocytes, the arrangement of collagen fibers, and the density of proteoglycan in the MgSO4 group were better than those in other experimental groups. At 35 days postoperatively, the gene expression of IL-1 ß and MMP-3 and the protein expression of CaM and TRPV5 in synovium in the MgSO4 group was lower than that in the NaCl group and CaCl2 group. CONCLUSION: Intra-operative irrigation with magnesium sulfate solution can inhibit the inflammatory factors and the expression of TRPV5, which can also reduce collagen loss and delay cartilage degeneration. Therefore, the use of magnesium sulfate in intra-operative irrigation may be an ideal choice to prevent PTOA.
