OBJECTIVETo explore clinical outcomes of retrograde interlocked intramedullary nailing with tibia bone graft fusion in treating end-stage ankle arthritis.

METHODSFrom November 2014 to April 2016, 22 patients with end-stage ankle arthritis were treated with retrograde interlocked intramedullary nailing with tibia bone graft fusion, including 9 males and 13 females aged from 30 to 65 years old with an average of 48.5 years old. Seven patients had obvious varus deformity, and other 15 patients' appearance were normal. Operative time, blood loss, fracture healing time and complications were observed and compared, AOFAS and VAS score were applied for evaluate ankle joint function and pain degree before operation and 9 months after operation.

RESULTSAll patients were followed up from 12 to 24 months with an average of 18.6 months. The incision were healed at stage I , and no complications occurred. Operative time ranged from 80 to 120 min with an average of 90 min;blood loss ranged from 15 to 50 ml with an average of 30 ml;fracture healing time was from 10 to 18 weeks with an average of 14 weeks. AOFAS score at 9 months after operation was 88.00±3.45, while 54.82±2.98 before operation, and there was statistical significance; 8 cases obtained excellent results, 12 good and 2 moderate. There was significant difference in VAS score between preoperative(3.96±1.27) and 9 months after operation(9.37±0.55).

CONCLUSIONSRetrograde interlocked intramedullary nailing with tibia bone graft fusion for the treatment of end-stage ankle arthritis has advantages of stable fixation, less trauma, less blood loss, bone union and rapid recovery of function, and could relieve pain obviously.

OBJECTIVETo investigate the association between single nucleotide polymorphisms (SNPs) of casein kinase I gamma 2 (CSNK1G2) gene and children with familial febrile convulsions.

METHODSThe study samples were collected from unrelated Chinese Han population of Hebei province, including a cohort of 53 children with familial febrile convulsions(FC) and a control cohort of 101 individuals. Genotypes of SNPs rs2074882, rs740423, rs2277737, rs4806825, rs1059684 were typed by polymerase chain reaction-restriction fragment length polymorphism.

RESULTSThe frequencies of the five SNPs complied well with the Hardy-Weinberg equilibrium in FC group and normal group. The distribution of genotype and frequencies of alleles of the SNPs rs740423, rs2277737, rs1059684 in familial febrile convulsions group was significantly different from that in control group. No significant difference was observed in the distribution of genotypes and frequencies of alleles at SNP rs2074882 between two groups. Analysis on rs4806825 was not made owing to its less allele frequency.

CONCLUSIONThese data indicate that SNPs rs740423, rs2277737, rs1059684 of CSNK1G2 gene may contribute to familial febrile convulsions in children.

OBJECTIVETo summarize the surgical technique and the clinical results of small acetabular components combined with medial protrusio technique in primary total hip arthroplasty (THA) for the treatment of Crowe type IV congenital hip dislocation (CHD).

METHODSFrom January 2000 to December 2005, total 14 patients (16 hips) of Crowe type IV CHD underwent cementless THA (12 unilateral, 2 bilateral) with this new technique. There were 2 males and 12 females with an average age of 49 years (range, 38 to 75 years). The indications for surgery was severe hip pain and leg length discrepancy with difficulty in walking and activating. Cup design: Duraloc (Depuy, Warsaw, USA) in 10 hips, Pressfit S II (LINK, Germany) in 6 hips. The outside diameter of the cup was 42 to 44 mm; and the thickness of the polyethylene liner was 6 to 7 mm. Total hip replacement were performed with the medial protrusion technique to stabilize the fit of a hemispherical metal cup in the acetabulum. The hip functions were evaluated by Harris hip score. The muscle strength of the gluteus medius and gait were respectively evaluated in accordance with the standards of five and four classes.

RESULTSThe X-ray showed that the average superolateral bone coverage in these 16 hips (none of which had bone graft) was more than 98 percent. The cup was an average of (5.8 +/- 1.2) mm medial and (6.2 +/- 1.7) mm superior to the Ranawat triangle. The follow-up period ranged from 3 to 9 years. The Harris hip score improved from 25 to 32 preoperatively to 90 to 98 1 year postoperatively. X-ray showed that perforated area of the medial acetabulum were repaired with healed bone mud 4 to 8 months after operation. The rate of linear wear of the polyethylene liner averaged (0.10 +/- 0.03) mm each year. Until now, no aseptic loosening or osteolysis was identified around the acetabulum components, no acetabular components were revised for loosening or other reasons.

CONCLUSIONSmall acetabular components combined with medial protrusio technique is a simple, reliable and flexible surgical technique. Early and mid-term result in total hip arthroplasty with this technique for the treatment of Crowe type IV CHD is satisfactory.
