ObjectiveTo investigate the application and effectiveness of the biological type acetabular cup (diameter ＜44 mm) in adult Crowe type IV developmental dysplasia of the hip (DDH). MethodsBetween April 2001 and August 2013, biological type acetabular cup was used in total hip arthroplasty for the treatment of Crowe type IV DDH in 16 cases (20 hips). There were 3 males and 13 females, aged 31-69 years (mean, 49 years). Unilateral hip was involved in 12 cases, and bilateral hips in 4 cases. The patients showed pain of the hip joint and inequality of lower limb (shortening of affected limb 1.8-6.0 cm in length, 3.5 cm on average). Acetabular deformity, the relationship and the severity of femoral head dislocation were comfirmed on the X-ray films. The preoperative Harris score was 34.0±6.9. ResultsAll patients achieved healing of incision by first intention, with no complication of infection or neurovascular injury. Sixteen cases were followed up 4-12 years (mean, 7.5 years). At 2 weeks after operation, dislocation occurred in 2 cases, and were fixed with plaster for 3 weeks after reduction of the hip. Postoperative X-ray films showed complete reduction of femoral head; the average acetabular coverage of the cup of the weight-bearing area was 98.5% (range, 98.2%-99.1%). The cup from the Ranawat triangle was 4.6-7.0 mm (mean, 5.8 mm) in medial shifting, and was 4.5-7.9 mm (mean, 6.2 mm) in elevation, it located at cup lateral surface area inside the iliopectineal line and the Kohler line (＜40%); the cup abduction angle was (45±5)°, and the anteversion angle was (10±5)°. The other patients had no prosthesis loosening except 1 patient having extensive acetabular prosthesis loosening because of acetabular osteolysis at 12 years after operation. The hip Harris score was significantly improved to 85.0±7.5 at 1 year after operation (t=14.34, P=0.01). ConclusionThe acetabular grinding process to retain enough bone combined with a small cup of biological prosthesis treating adult Crowe type IV DDH has the advantages of satisfactory coverage and initial acetabular fixation, so good early and mid-term effectiveness can be obtained.
Objective To investigate the primary peripheral non-small cell lung cancer (NSCLC) in stage T1 of TNM (UICC2011) (the tumor size≤3 cm) and to find out the lymphadenectomy way which will benefit patients most. Methods We retrospectively analyzed the clinical data of 60 patients with primary peripheral NSCLC in our hospital between November 2014 and May 2015. There were 26 males and 34 females at age of 34-76 (57.91±7.75) years. The lymph nodes dissection and metastasis were recorded. Results The total number of intrathoracic lymph nodes dissection is 1 208,with an average of 20.1, including 33 metastasis lymph nodes. The metastasis rate was 2.73%. A total of 51 patients were not found the mediastinum and hilum metastasis lymph node through the routine pathological detection method，while metastasis lymph node in section 12 and (or) 13 and (or) 14 group were found in 3 patients in our trial. The detection rate was 5.89%. For stage T1 primary peripheral NSCLC, with increasing tumor size, lymph node metastasis rate was gradually increased. The patients with solid lesions were more likely to have lymph node metastasis than those with non-solid lesions (pure ground-glass nodules or mixed ground-glass nodules) which generally did not find lymph node metastasis. Conclusion The lymph node metastasis rate in stage T1 primary peripheral NSCLC is related to the tumor size, nature, histological type, local pleural stretch in imaging. The dissection of lung lymph node (12+13+14 groups)may be able to find simple intrapulmonary lymph nodes metastasis. It is important to the selection of delineated staging and treatment program in stage T1 primary peripheral NSCLC.
ObjectiveTo comparatively analyze the effect of one-stage nonstented tubularized incised plate urethroplasty (TIP) on operative pain and compl ication by comparing with urethral catheter and urethral stent drainages. MethodsBetween March 2010 and June 2013, 214 cases of distal and mid-shaft hypospadias underwent TIP, and the cl inical data were analyzed retrospectively. The patients were divided into 3 groups based on different urinary drainage techniques: indwell ing urethral catheter was used in 68 cases (group A), indwell ing urethral stent in 70 cases (group B), and nonstented drainage in 76 cases (group C). There was no significant difference in age, hypospadias type, and accompany malformation among 3 groups (P>0.05). At 2 days after operation, Wong-Banker facial scale (WBS) and Children's Hospital of Eastern Ontario Pain Scale (CHEOPS) were used for pain and praxiology assessment. The complications after operation also were observed and compared among 3 groups. ResultsAll patients were followed up 6-25 months (median, 11.8 months). At 2 days after operation, the median WBS scores were 4.0 (0-10), 3.5 (0-10), and 3.0 (0-10) in groups A, B, and C, respectively; median CHEOPS pain scores were 6.0 (1-13), 6.0 (1-13), and 4.0 (1-11), respectively. The WBS pain score and CHEOPS pain score in group C were significantly lower than those in groups A and B (P<0.05), but there was no significant difference between group A and group B (P>0.05). The postoperative complication occurred in 27 cases (39.7%) of group A, 29 cases (41.4%) of group B, and 13 cases (17.1%) of group C; two or more than two complications occurred in 14, 15, and 9 cases, respectively. There was significant difference in total incidence of postoperative complication among 3 groups (P<0.05). The incidences of postoperative overactive bladder, bladder spasms, urinary tract infection, and fistula in group C were significantly lower than those in groups A and B (P<0.05). There was no significant difference in incision infection, acute urinary retention, urinary extravasation, meatal stenosis, and urethral stricture among 3 groups (P>0.05). ConclusionOne-stage nonstented TIP is suitable for distal and mid-shaft hypospadias and could reduce postoperative pain and complications compared with the traditional postoperative indwell ing urethral catheter and indwell ing urethral stent.
ObjectiveTo analyze the mid-and long-term effectiveness of the 3rd-generation ceramic-on-ceramic (CoC) total hip arthroplasty (THA) in the younger patients. MethodsA retrospective analysis was made on the clinical data of 68 younger patients (73 hips) who accepted the 3rd-generation CoC THA between March 2001 and May 2009. Of 68 cases, 39 was male and 29 was female with the average age of 38.6 years (range, 18-50 years); there were 15 cases (15 hips) of osteonecrosis of the femoral head, 9 cases (9 hips) congenital dysplasia of the hip, 5 cases (8 hips) of ankylosing spondylitis, 10 cases (10 hips) of osteoarthritis of the hip joint, 12 cases (12 hips) of traumatic hip arthritis, 12 cases (12 hips) of femoral neck fracture, 4 cases (6 hips) of rheumatoid hip arthritis, and 1 case (1 hip) of tumor of the femoral neck. The Harris score and University of California Los Angeles (UCLA) score were used to evaluate the hip joint function and activity level respectively. The visual analogue scale (VAS) was used to assess postoperative thigh pain. Radiological signs of osteolysis, loosening, and alumina ceramic related complications were evaluated continuously. And the KaplanMeier survival analysis was used to assess the prosthesis survival. ResultsThe average duration of follow-up was 9.7 years (range, 6-14 years). Sandwich ceramic liners fracture was observed in 3 cases (3 hips), and revision was performed; 1 case had "squeaking" hip because of physical activity. At last follow-up, Harris score and UCLA score were significantly improved when compared with preoperative scores (P<0.05). Bony healing was obtained in all patients, without osteolysis, loosening, and thigh pain. The VAS score was 0. The 5-year and 10-year cumulative survival rates for ceramic fracture revision were 98.6% and 95.9%, and the 5-year and 10-year cumulative survival rates for osteolysis and loosening revision both were 100%. ConclusionThe 3rd-generation CoC prosthesis offer an excellent option for younger patients in THA and the mid-and long-term effectiveness are satisfactory.
ObjectiveTo investigate the effectiveness of rotating-platform prosthesis for valgus knee deformity in total knee arthroplasty (TKA). MethodsA retrospective analysis was made on the clinical date of 25 cases (28 knees) of valgus deformity undergoing primary TKA by using Gemini MK II rotating-platform prosthesis. There were 6 males (7 knees) and 19 females (21 knees), aged from 47 to 82 years, with an average age of 64.8 years. The unilateral knee was involved in 22 cases and the bilateral knees in 3 cases. The causes included osteoarthritis in 20 cases (22 knees), rheumatoid arthritis in 4 cases (5 knees), and traumatic arthritis in 1 case (1 knee). The disease duration was 2-22 years (mean, 10.4 years). The main clinical symptoms were arthralgia combined with limited movement. According to the Keblish grade, there were 13 knees of mild deformity, 11 knees of moderate deformity, and 4 knees of severe deformity. ResultsAll incisions healed by first intension. No complications of infection, cutaneous necrosis, deep venous thrombosis, and pulmonary embolism occurred. The postoperative follow-up duration was 12-60 months (mean, 25.4 months). Medial instability and palsies of nervus peroneus communis occurred in 1 and 2 cases respectively, and all were cured after symptomatic treatment. No patellar and polysthylene insert dislocation, prosthetic loosening or infection was observed. The Hospital for Special Surgery (HSS) score, femoral tibial angle, maximun flexion and extension angles, knee range of motion, and patellar score were significantly improved at last follow-up when compared with preoperative ones (P<0.01). ConclusionThe rotating-platform prosthesis for valgus deformity can obtain satisfactory effectiveness, but it requires precise soft tissue balancing technology, and the long-term effectiveness remains further observation.
