BACKGROUND: It is still controversial whether antibiotic-loaded bone cement can prevent wound deep infection in the primary hip arthroplasty. OBJECTIVE: To retrospectively observe the effect of antibiotic-loaded bone cements in primary hip arthroplasty. DESIGN, TIME AND SETTING: A retrospective case analysis was performed for the patients undergoing primary hip arthroplasty at Department of Orthopedics, Peking University Third Hospital from February 2004 to January 2007. PARTICIPANTS: 227 consecutive patients (233 hips) underwent primary hip arthroplasty with the same antibiotic-loaded bone cement, including 69 male and 115 female, and 184 cases (191 hips) were followed up for 3-46 months. METHODS: Fifty-four patients over 71 years old with femoral neck fracture were treated with bipolar femoral head replacement. 130 patients underwent total hip arthroplasty. Seventeen patients with massive acetabular bone defect were reconstructed with impaction autogenous and heterogenous bone grafting plus mesh; 3 patients underwent acetabular structural bone grafting. Both acetabular and femoral side prosthesis were antibiotic-loaded bone cements (Refobacin~-Palacos~R 40 or Cemex~ Genta). MAIN OUTCOME MEASURES: Deep infection after operation. RESULTS: 227 patients (233 hips) did not develop early deep infection after surgery. 184 cases (191 hips) did not occur deep infection during the follow up. However, 15 cases developed swelling on the affected site or skin temperature increase, or pain surrounding joint, and underwent blood sedimentation and C-reactive protein examinations; 12 cases had normal blood sedimentation and 3 had increased blood sedimentation including 1 with rheumatoid, 1 with senile chronic bronchitis, and 1 with undetermined cause. All the 3 patients restored one month later. Fourteen patients had C-reactive protein within normal scope, and 1 with increased C-reactive protein caused by rheumatoid arthritis, but restored 6 weeks later. CONCLUSION: Antibiotic-loaded bone cements in primary hip arthroplasty can reduce incidence of deep infection.

Objective To evaluate the effects of Achilles tendon lengthening on talipes equinus in children with spastic cerebral palsy. Methods From December, 2013 to June, 2014, seventeen spastic cerebral palsy children with talipes equinus (34 feet) received Achilles ten-don lengthening. Ankle dorsiflexion range of motion (ROM) and surface electromyography from tibialis anterior and medial head of gastroc-nemius were measured before and 8 to 12 months after operation, respectively. ROM of passive and active dorsiflexion, root mean square (RMS) of tibia muscle group and co-contraction ratio (CR) when standing were compared. Results The ROM of ankle passive and active dorsiflexion increased (Z>4.867, P<0.001), while the RMS of gastrocnemius muscle decreased when ankle passively dorsiflex (t=4.31, P<0.001). RMS of tibialis anterior and gastrocnemius muscle changed little when standing (Z<1.291, P>0.05), while CR reduced (t=2.38, P<0.05). Conclusion Achilles tendon lengthening can improve the coordination of tibia muscle group to increase the ROM of ankle for chil-dren with talipes equinus after spastic cerebral palsy.

Objective To determine the morphology, bacteria and endotoxin content of bio-films on the inner surface of PVC tubes in hemodialysis water treatment system. Methods We dissolved biofilms of segments before and after reverse osmosis machine for bacterial count and identification. We studied biofilm structure of segments before and after reverse osmosis machine with eyes and scanning electron microscope. Biofilms of all 7 segments were dissolved for qualitative and quantitative assay of endotoxin. Results The inner surface of segment before reverse osmosis machine was homogeneously distributed with activated carbon powder deposition. The segment after reverse osmosis machine was normal. With scanning electron microscope, biofilm with successive surface and sandwich was found on the inner surface of segment before reverse osmosis machine, formed by clustering bacillus, activated carbon powder and some coccus. Bacteria of the same shape and length were found on segment after reverse osmosis machine, but fewer and looser. Bacterial culture and identification showed the former was mostly gram-negative bacillus, the latter was only a few micrococcus. Endotox-in of biofilm was between 2. 0 EU/mL and 4. 0 EU/mL. Quantitative assay showed: segment after softener (2.821 ±0. 807) EU/mL; segment after active charcoal canister(3. 635 ±0. 427) EU/ mL; segment before reverse osmosis machine (3.687 ±0.271) EU/mL; segment after reverse osmosis machine (2. 041 ±0. 295) EU/mL; exit of power pump (1. 983 ±0. 390) EU/mL; the 1st dead space (2. 373 ± 0. 535) EU/mL; and the 2nd dead space (2. 858 ± 0. 690) EU/mL. Conclusion Biofilms are found on the inner surface of segment before and after reverse osmosis machine . Endotoxin level from high to low is as follows: segment before reverse osmosis machine, segment after active charcoal canister, the 2 nd dead space, segment after softener, the 1 st dead space, segment after reverse osmosis machine, exit of power pump. The character of the bacteria and endotoxin of the biofilm can help us find better ways to control them.
