ObjectiveTo explore the method and experience in correction of pectus carinatum with minimally invasive procedure. MethodsBetween June 2010 and January 2014, 30 patients with pectus carinatum were corrected by minimally invasive procedure. There were 21 boys and 9 girls whose average age was 13 years and 2 months (range, from 8 years and 10 months to 18 years and 9 months), including 24 cases of first operation, 2 recurrence after traditional pectus carinatum correction, and 4 cases secondary to median thoracotomy. Thirty patients had symmetric and asymmetric mild pectus carinatum. ResultsThe operation was performed successfully in all patients, and no severe complication occurred. The operation time was 42-95 minutes (mean, 70 minutes). The bleeding volume during operation was 4-30 mL (mean, 10 mL). The time from operation to discharge was 6-10 days (mean, 7 days). The average time of follow-up was 25 months (range, 9-54 months). All surgical wound healed primarily with no infection. The X-ray films showed slight pneumothorax in 7 cases, and it was absorbed after 1 month without treatment. Loosening of internal fixation was found in 1 patient because of trauma at 6 months, and operation was performed again. The bar was removed at 2 years in 21 patients. The patients had good thoracic contour and normal activity. ConclusionMinimally invasive procedure for correction of pectus carinatum is safe and will get satisfactory effect in maintaining thoracic contour. It has also less trauma and shorter operation time.
ObjectiveTo summarize the clinical characteristics and treatment of acute cellulitis of shank after total knee arthroplasty. MethodsWe retrospectively analyzed the clinical data of five patients with delayed acute cellulitis of shank after total knee arthroplasty treated in our hospital between January 2008 and January 2013. The clinical characteristics, treatment and prognosis of the disease were then summarized and analyzed. ResultsThe delayed acute cellulitis of shank after total knee arthroplasty was mainly caused by tinea pedis, which resulted in skin damage and bacteria diffusion. The main clinical manifestations were pain and swelling around the knee joint and shank. The laboratory test found the increasing of C-reactive protein, erythrocyte sedimentation rate, white blood cell and neutrophils. Two cases were caused by hemolytic streptococcus according to blood culture. All patients were discharged after treatment without periprosthetic infection. ConclusionAccording to the typical clinical manifestations and laboratory test, the diagnosis of delayed acute cellulitis of shank is not difficult. Timely and comprehensive treatment should be emphasized to seek and eradicate the primary lesions, such as tinea pedis, subcutaneous ulcer and carbuncle.
ObjectiveTo analyze the methods of offside reconstruction in total hip arthroplasty (THA) for severe osteoarthritis. MethodsBetween July 2009 and June 2011,18 cases (18 hips) of severe osteoarthritis of the hip were treated by THA,including 14 males and 4 females with a mean age of 55.4 years (range,47-72 years).The disease duration was 11-74 months (mean,33.6 months).The left hip was involved in 11 cases and the right hip in 7 cases.The hip Harris score was 34.6±5.3.The lower limb discrepency was observed in 15 cases.Thomas sign,Patrick sign,and Trendelenburg sign were positive in all cases.All patients received THA; during operation,standard femoral neck osteotomy was performed and the correct rotation center was chosen to reconstruct offside. ResultsAll the incisions healed primarily.Common peroneal nerve injury occurred in 1 case and was cured after symptomatic treatment for 3 months,and the other patients had no complication.The mean follow-up period was 43.5 months (range,30-53 months).All patients achieved pain relief,and returned to normal gait.The X-ray films showed no dislocation of the hip or prosthetic loosening.Lower limb discrepency was observed in 6 cases.The mean offside difference between normal and ipsilateral side was 0.4 mm (range,0.1-0.7 mm).At last follow-up,the hip Harris score was 83.0±7.1,showing significant difference when compared with preoperative score (t=-22.96,P=0.01); the hip range of motion was significantly increased when compared with preoperative one (P<0.05). ConclusionThe offside reconstruction can accurately be carried out by making precise template and vernier caliper measurement,selecting suitable prosthesis preoperatively,maintaining the proper femoral calcar length,adjusting the length of the neck and neck-shaft angle,releasing the soft tissue reasonably during THA for severe osteoarthritis,and the short-term effectiveness is satisfactory.
