Surgical correction of coxa vara: Evaluation of neck shaft angle, Hilgenreiner-epiphyseal angle for indication of recurrence.

BACKGROUND: Coxa vara is a hip deformity in which the femoral neck-shaft angle decreases below its normal value. Standard surgical treatment for this condition is corrective valgus osteotomy. Appropriate correction of the Hilgenreiner-epiphyseal angle is important to prevent recurrence. The purpose of this study is to: 1) evaluate the recurrence of the deformity at the latest follow up; and 2) find the appropriate angle of correction associated with the lowest recurrence. METHODS: 34 hips in 31 patients who underwent surgery for treatment of coxa vara from 2005 to 2014 were included. Patient-reported outcomes, Hilgenreiner-epiphyseal angle, and neck-shaft angle were assessed preoperatively, postoperatively, and at latest follow-up. RESULTS: The mean age at surgery was 10.99, with a range of 5-30, years. Preoperative neck-shaft angle ranged from 60 to 100 degrees, and Hilgenreiner-epiphyseal angle ranged from 60 to 90 degrees. At the latest follow up, the neck-shaft angle ranged from 120 to 135 degrees and the Hilgenreiner-epiphyseal angle ranged from 22 to 35 degrees (p < 0.001). The Harris hip score improved from 47.20 (34-66) to 79.68 (60-100) (p < 0.001). There was no recurrence of deformities at the mean follow up of 37.87 months. CONCLUSION: Surgical correction of coxa vara in various pathologies can be done successfully with the Hilgenreiner-epiphyseal angle corrected to ≤ 35 degrees or the neck shaft angle corrected to > 120 degrees in order to prevent recurrence of the deformity. Majority of the patients were reported improvement of hip function. However, a longer-term follow up is required to determine further outcomes regarding to recurrence of the deformity.

Congenital metacarpal synostosis treated by double bone blocks technique: a case report from Thailand.

Congenital metacarpal synostosis is a rare congenital anomaly in the hand, especially in our area. There were several reports of surgical techniques for correction deformities. We report this rare condition in our hospital and treatment with the metacarpal osteotomy and double bone blocks technique of grafting.

Treatment of de Quervain disease with triamcinolone injection with or without nimesulide. A randomized, double-blind, placebo-controlled trial.

BACKGROUND: There is uncertainty as to whether supplemental oral nonsteroidal anti-inflammatory medication improves the effectiveness of steroid injections in the treatment of de Quervain disease. We tested the hypothesis that there are no significant differences in the success rates when this condition is treated with triamcinolone injection with or without supplemental oral nimesulide. METHODS: In a randomized, double-blind trial, 160 patients with de Quervain disease received an injection of 10 mg of triamcinolone acetonide and either 200 mg of oral nimesulide for seven days (eighty patients) or placebo tablets for seven days (eighty patients). An independent, blinded evaluator assessed the primary outcomes (tenderness, pain, and the result on the Finkelstein test) at three weeks after injection. Adverse reactions were assessed, and probabilities of recurrence for both groups were compared. Factors possibly predictive of disease recurrence were also assessed. RESULTS: The success rate after one injection was 67% in the nimesulide group and 68% in the placebo group. The overall success rates after single or multiple injections with a mean follow-up of 13.6 months were 95% for both groups. No significant differences were noted with respect to the success rates (p = 0.69) or pain scores after treatment (p = 0.11). The most common adverse reactions to triamcinolone injection and nimesulide were pain after injection and dyspepsia, respectively. The symptoms of de Quervain disease recurred in 33% of the patients in the nimesulide group and in 37% of those in the placebo group. The median time of recurrence was at the fifth month in the nimesulide group and at the fourth month in the placebo group. The recurrence of symptoms was significantly (p = 0.01) related to the presence of crepitation (relative risk, 2.13; 95% confidence interval, 1.19 to 3.80). CONCLUSIONS: Supplemental oral administration of the nonsteroidal anti-inflammatory drug nimesulide does not improve the effectiveness of a single injection of triamcinolone acetonide in the treatment of de Quervain disease. Patients with crepitation in the first dorsal compartment during thumb extension or abduction are at increased risk for recurrence of this disease. LEVEL OF EVIDENCE: Therapeutic study, Level I-1b (randomized controlled trial [no significant difference but narrow confidence intervals]).
