Short-term effect of double bundle reconstruction of posterior cruciate ligament with total internal short tendon technique / 中国骨伤

OBJECTIVE@#To explore the method and curative effect of double bundle reconstruction of posterior cruciate ligament with total internal short tendon technique.@*METHODS@#From October 2010 to June 2018, 50 patients with simple posterior cruciate ligament rupture were admitted, including 35 males and 15 females, ranging in age from 20 to 45 years old, 16 with acute injury and 34 with old injury. The posterior cruciate ligament (PCL) was reconstructed by double bundle technique with the whole internal short tendon. The two ends of the transplanted ligament were fixed by titanium plate suspended with adjustable loop. The Lysholm knee score and IKDC score were used to evaluate the clinical effects.@*RESULTS@#All the 50 patients were followed up, and the duration ranged from 6 to 60 months, with a mean of (28.84±9.52) months. At the latest follow up, the knee joint activity returned to normal range. The median value of Lysholm knee score was 54 before operation and 100 after operation. According to the IKDC score, there were 0 case of grade A, 0 case of grade B, 20 cases of grade C and 30 cases of grade D before operation;29 cases of grade A, 19 cases of grade B, 1 case of grade C and 1 case of grade D after operation;the difference was statistically significant (<0.01).@*CONCLUSION@#Arthroscopic double bundle reconstruction of posterior cruciate ligament with short internal tendon is safe and reliable, with less tendon transplantation, more stable fixation, and more bone reserve, which is beneficial for healing and renovation. The short term effect is positive.

Hurthle cell thyroid tumor: an analysis of 28 cases / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To explore the clinical features and the combined treatment modality of Hurthle cell thyroid tumor (HCT).</p><p><b>METHODS</b>Twenty-eight cases of HCT treated between 2001 and 2009 were analyzed retrospectively.</p><p><b>RESULTS</b>The age of the patients ranged from 18 to 72 years (with a median of 46.5 years); 22 females and 6 males. The main symptoms were thyroid solitary node or mass (22 cases) and multiple nodule (6 cases), 2 cases with cervical lymph node metastasis. All of the patients underwent surgery, 11 cases with thyroid lobectomy, 11 cases with thyroid lobectomy plus isthmusectomy, 4 cases with subtotal thyroidectomy, and 2 cases with thyroid lobectomy plus isthmusectomy and combined with modified radical cervical lymph node dissection. Postoperative pathological examination showed that 22 cases were Hurthle cell adenomas and 6 cases were Hurthle cell carcinomas, 1 of them with cervical lymph node metastasis. Twenty-one patients with Hurthle cell adenomas were followed up for 6 months to 7.5 years (with a median of 45 months) and 6 patients with Hurthle cell carcinomas for 3 to 8 years (with a median of 54 months), with no recurrence and death case.</p><p><b>CONCLUSIONS</b>HCT is a potential malignant neoplasm. There are some difficulties in the diagnosis of HCT by frozen section. Surgery is an effective treatment for HCT. L-Thyroxine can be used to inhibit TSH excretion.</p>
