  • TREATMENT OF OSTEONECROSIS OF FEMORAL HEAD BY CORE DECOMPRESSION COMBINING WITH AUTOLOGOUS CORTICAL SUSTAINING BONE AND CANCELLOUS BONE GRAFT

    Objective To study the effect of core decompression combining with autologous cortical sustaining bone and cancellous bone graft in treating osteonecrosis of the femoral head (ONFH). Methods From February 2004 to May 2008, 64 patients (77 hi ps) with ONFH were treated with core decompression combining with autologous cortical sustaining bone and cancellous bone graft, including 45 males and 19 females and aging 23 to 60 years with an average age of 43 years. There were 51 cases of unilateral ONFH and 13 cases of bilateral ONFH. ONFH was caused by alcohol in 39 cases(47 hi ps), by steroid in 21 cases (26 hi ps), and by trauma in 4 cases (4 hi ps). The disease course was 1-12 years. The pain time was 2-14 months (average 7 months). All the cases underwent imageology and postoperation pathology examination to confirm the diagnosis of ONFH. According to Association Research Circulation Osseous (ARCO) international classification of osteonecrosis, 17 cases (23 hips) were classified as stage I A, 2 cases (3 hips) as stage I B, 21 cases (24 hips) as stage II A, 2 cases (2 hips) as stage II B, 4 cases (4 hips) as stage II C, and 18 cases (21 hips) as stage III A. The outcome was evaluated both cl inically by Harris score and radiologically by imageology. Results A total of 59 cases (69 hips) were followed up for 12-62 months with an average of 32.1 months. The Harris score was 87.12 ± 8.68 at 12 months after operation, showing significant difference (P lt; 0.05) when compared with the preoperative one (68.38 ± 14.49). The results were excellent in 39 hips, good in 18 hips, fair in 6 hips, and poor in 6 hip; and the excellent and good rate was 82.6%. Radiographic evaluation was 21 hips (30.4%) of grade I, 42 hips (60.9%) of grade II, and 6 hips (8.7%) of grade III. One case had the compl ication of il ium bone donor site, 21 cases had l ittle pain or numbness, and the other cases had no uncomfortable compl ication. Conclusion The method of core decompression combining with autologous cortical sustaining bone and cancellous bone graft can improve the means of bone grafts, prevent the collapse of the femoral head, and is less traumatic than common procedures.

  • EXPERIMENTAL STUDY ON ESTABLISHMENT OF A SIMPLE MODEL OF RATS CRUSH INJURY-CRUSH SYNDROME

    Objective To establish a repeatable, simple, and effective model of rat crush injury and crush syndrome (CS) so as to lay a foundation for further study on CS. Methods A total of 42 female Sprague Dawley rats (2-month-old, weighing 160-180 g) were divided randomly into the control group (n=6) and experimental group (n=36). The rats of the experimental group were used to establish the crush injury and CS model in both lower limbs by self-made crush injury mould. The survival rate and hematuria rate were observed after decompression. The biochemical indexes of blood were measured at 2, 4, 8, 12, 24, and 48 hours after decompression. The samples of muscle, kidney, and heart were harvested for morphological observation. There was no treatment in the control group, and the same tests were performed. Results Seven rats died and 15 rats had hematuria during compression in the experimental group. Swelling of the lower limb and muscle tissue was observed in the survival rats after reperfusion. The liver function test results showed that the levels of alanine transaminase and aspartate aminotransferase in the experimental group were significantly higher than those in the control group (P lt; 0.05). The renal function test results showed that blood urea nitrogen level increased significantly after 2 hours of decompression in the experimental group, showing significant difference when compared with that in the control group at 12, 24, and 48 hours after decompression (P lt; 0.05); the creatinine level of the experimental group was higher than that of the control group at 4, 8, 12, and 24 hours, showing significant difference at 8, 12, and 24 hours (P lt; 0.05). The serum K+ concentration of the experimental group was higher than that of the control group at all time, showing significant difference at the other time (P lt; 0.05) except at 2 hours. The creatine kinase level showed an increasing tendency in the experimental group, showing significant difference when compared with the level of the control group at 4, 8, 12, and 24 hours (P lt; 0.05). The histological examination of the experimental group showed that obvious edema and necrosis of the muscle were observed at different time points; glomeruli congestion and swelling, renal tubular epithelial cell degeneration, edema, necrosis, and myoglobin tube type were found in the kidneys; and myocardial structure had no obvious changes. Conclusion The method of the crush injury and CS model by self-made crush injury mould is a simple and effective procedure and the experimental result is stable. It is a simple method to establish an effective model of rats crush injury and CS.

  • BIOMECHANICAL COMPARATIVE STUDY ON PROXIMAL FEMORAL LOCKING PLATE AND Gamma3 FOR TREATMENT OF STABLE INTERTROCHANTERIC FRACTURE

    ObjectiveTo compare the biomechanical properties between the proximal femoral locking plate and Gamma3 for fixing stable intertrochanteric fracture so as to provide a theoretical basis for selecting internal fixation in the clinical application. MethodsFive pairs of antiseptic femur specimens were selected. Specimens of each pair of matching were randomly divided into groups A and B (n=5). All specimens were made the intertrochanteric fracture of 31A1.1 type according to AO/Association for the Study of Internal Fixation (AO/ASIF) classification. Fracture was fixed with Gamma3 in group A and with proximal femoral locking plate in group B. The axial compression, destruction, and torsion tests were carried out on the mechanical testing machine. ResultsAxial compression test:The load-displacement curve of groups A and B was basically a straight line; axial stiffness of groups A and B was (621.00±36.48) N/mm and (542.55±46.94) N/mm respectively, showing significant difference (t=3.648, P=0.036). Destruction test:The maximum yield load of groups A and B was (4 394.82±450.37) N and (2 987.54±112.14) N respectively, showing significant difference (t=5.433, P=0.032). After loading maximum yield load, femoral fracture occurred again, and internal fixation and bone interface loosening were observed in group A; bending and breaking of proximal locking screw for internal fixation were found in group B, but loosening of internal fixation and bone interface was more obvious in group A than in group B. Torsion test:The torque of specimens in 2 groups increased with the increase of torsion angle (P < 0.05), the torque corresponding to the torsion angle in group B was larger than that in group A, but the difference was not significant (P > 0.05). The torsional stiffness of groups A and B was (1.78±0.16) N·mm/deg and (2.01±0.08) N·mm/deg respectively, showing no significant difference (t=-3.833, P=0.162). ConclusionProximal femoral locking plate and Gamma3 in the treatment of stable intertrochanteric fracture have good biomechanical properties, which can meet the requirements of minimal invasion, strong internal fixation, and early activity.
