Objective To summarize mid-term effectiveness of modified arthroscopic suture button fixation Latarjet procedure for treatment of recurrent anterior shoulder dislocations. Methods Between January 2018 and October 2020, 30 patients with recurrent anterior shoulder dislocations were treated with modified arthroscopic suture button fixation Latarjet procedure. There were 19 males and 11 females with an average age of 27.3 years (range, 18-41 years). The shoulder dislocation occurred 3-7 times, with an average of 4.9 times. The time from the last dislocation to operation was 3-10 days, with an average of 4.1 days. Glenoid defects exceeded 20% in all cases. There were 27 cases of Hill-Sachs lesions. The joint pain and function were estimated by visual analogue scale (VAS) score, University of California, Los Angeles (UCLA) score, Rowe score, American Association for Shoulder and Elbow Surgery (ASES) score, Walch-Duplay score, and the range of external rotation at 0° and external rotation at 90° abduction of shoulder before operation and at 1 month, 6 months, and last follow-up. The X-ray film, CT scan and three-dimensional reconstruction were reviewed to observe the position, healing, and absorption of the coracoid graft, correction of glenoid defect, and joint degeneration.Results The operation time ranged from 51 to 79 minutes, with an average of 68.4 minutes. All incisions healed without complications such as nerve or blood vessel injury. All patients were followed up 36-60 months with an average of 44.6 months. The VAS score, UCLA score, Rowe score, ASES score, Walch-Duplay score, and the range of external rotation at 0° and external rotation at 90° abduction after operation significantly improved when compared with preoperative values (P<0.05). All indicators further improved with time, and the differences between different time points after operation were significant (P<0.05). Imaging review showed that the coracoid graft was located in the anteroinferior glenoid at 1 day after operation, and no occurrence of shoulder osteoarthritis was found during follow-up. The anatomical structure of the glenoid was normal, and no delayed healing or non-union of the coracoid graft occurred. At 20 months after operation, arthroscopic re-exploration was performed in 1 case due to fracutre caused by falling injury revealed the good shaping of the coracoid graft, smooth glenoid, and no bone resorption or osteoarthritis. ConclusionFor recurrent anterior shoulder dislocations, the modified arthroscopic suture button fixation Latarjet procedure can obtain good recovery of shoulder function and low incidence of complications and has a good mid-term effectiveness.
Abstract:Objective To evaluate the effects of modified uhrafihration （MUF）on blood rheology in infants after open cardiac surgery. Methods According to admission number, 22 infants of body weight less than 10 kilograms with ventricular septal defect （VSD） and pulmonary hypertension （PH） were divided into control group （10 infants, the mantissa of their admission number was odd number） and experimental group （12 infants, the mantissa of their admission number was even number）. Cases in control group didn＇t undergo MUF at the end of cardiopulmonary bypass （CPB）, while cases in experimental group underwent MUF; the flow rate of MUF ranged from 10 ml/min · kg to 15 ml/min · kg. MUF lasting for 10-15 minutes. Blood samples were repeatedly collected as following time： before operation, at the end of CPB, 15 minutes after CPB or the end of MUF, 2, 24 h after operation. Blood sample of 2. 5 ml was collected from the radial artery with hepathrom test-tube. The changes of relative indexes of the blood rheology were observed by MDK-3200 completely automatic dual pathways blood rheology testing analysator at 37±1 C. Results Hemoglobin, hematocrit, red cell count, blood yielding stress, plasma viscosity, the whole blood viscosity at high shear rate, the whole blood viscosity at middle shear rate and low shear rate, the whole blood reduction viscosity at high shear rate and middle shear rate, the whole blood reduction viscosity at low shear rate and Casson viscosity in experimental group at the end of MUF were significantly higher than those in control group at 15 minutes after CPB （P〈0. 05）. There was no significant difference in red cell aggregation index and red cell deformity between two groups at each moment （P 〉 0.05 ）. Conclusion Hemoglobin, hematocrit and red cell count are significantly elevated through MUF after CPB. Whole blood viscosity in infants undergone open cardiac surgery after CPB with MUF is higher than those who didn＇t undergo MUF.
ObjectiveTo explore effectiveness of reduction and internal fixation via modified anterolateral supra-fibular-head approach in treatment of tibial plateau fractures involving posterolateral column.MethodsBetween January 2016 and September 2018, 19 patients diagnosed as tibial plateau fractures involving posterolateral column were treated with reduction and internal fixation via modified anterolateral supra-fibular-head approach. There were 11 males and 8 females with an average age of 43.2 years (range, 28-65 years). The causes of tibial fracture were traffic accident (12 patients), falling injury (5 patients), and falling from height (2 patients). According to the Schatzker typing, the tibial fractures were rated as type Ⅱ in 9 cases, type Ⅲ in 4 cases, type Ⅴ in 4 cases, and type Ⅵ in 2 cases. The time from injury to operation was 5-13 days (mean, 8.5 days). There were 2 patients with osteoporosis. The operation time, intraoperative blood loss, and postoperative complications were recorded. The knee X-ray film was reviewed regularly to observe the fracture healing. At last follow-up, the fracture reductions were evaluated by Rasmussen radiological score. The knee joint function was evaluated by Hospital for Special Surgery (HSS) score system.ResultsThe average operation time was 95 minutes (range, 65-130 minutes). The average intraoperative blood loss was 220 mL (range, 150-350 mL). All incisions healed by first intention. No complications such as infection or deep venous thrombosis occurred. All patients were followed up 12-20 months (mean, 15.4 months). X-ray films showed that the fractures healed with the healing time of 12-20 weeks (mean, 14.5 weeks). No complications such as loosening or breakage of internal fixation occurred. At last follow-up, according to the Rasmussen radiological score, the fracture reductions were evaluated as excellent in 13 cases, good in 4 cases, fair in 1 case, and poor in 1 case. HSS scores of knee joint function were excellent in 14 cases, good in 3 cases, fair in 1 case, and poor in 1 case. The knee joint range of motion was 90°-135°, with an average of 113.4°.ConclusionApplication of modified anterolateral supra-fibular-head approach in reduction and internal fixation for tibial plateau fractures involving posterolateral column has the advantages of full exposure, less trauma, safety, and reliable reduction and fixation.

ObjectiveTo investigate the clinical application of the modified Zitelli bilobed flaps in repairing soft tissue defect of lower one-third nose. MethodsBetween February 2009 and February 2014, 26 patients with soft tissue defect of lower one-third nose after resection of basal cell carcinoma underwent reconstruction using modified Zitelli bilobed flaps. There were 15 males and 11 females, aged 48-65 years (mean, 56 years). Tumor involved the skin layer in all patients. According to TNM staging, 19 cases were rated as TisN0M0 and 7 cases as T1N0M0. The disease duration was 1-5 years (mean, 3 years). The mass size ranged from 1.0 cm×0.5 cm to 1.5 cm×1.0 cm. The defect size ranged from 1.5 cm×1.0 cm to 2.0 cm×1.5 cm after resection of basal cell carcinoma. The modified ipsilateral Zitelli bilobde flaps were designed and harvested for one-stage repair of defect, and the double-leaf flap size ranged from 2.5 cm×2.0 cm to 3.0 cm×2.5 cm and 1.5 cm×1.0 cm to 2.0 cm×1.5 cm. The donor site defects were sultured directly. ResultsTwenty-six flaps survived and incision healed primarily. No postoperative complications of hematoma, infection, and necrosis of skin flap occurred. No stretching deformation of local organs, the shape of the nose and face was symmetric. Twenty-six patients were followed up 3-24 months (mean, 13 months). Nasal and facial appearance was good and had no obvious scar formation, and patients were satisfied with the appearance. There was no tumor recurrence during follow-up. ConclusionThe modified Zitelli bilobed flap to repair soft tissue defect of lower one-third nose (the defect diameter within 2.0 cm) can obtain satisfactory effectiveness in appearance.
To evaluate the efficacy and the surgical procedures of submandibular sialoadenectomy by a modified retroauricular approach. Methods Between October 2008 and April 2009, 8 patients with benign submandibular gland disorders underwent removal of benign submandibular gland lesions using a retroauricular approach. There were 4 males and 4 females with an average age of 38.5 years (range, 32-54 years), including 3 pleomorphic adenoma and 5 chronic sialadenitis with sialol ithiasis. The disease duration was from 2 months to 5 years. The anterior facial vein and the facial artery were reserved only by the l igation of branching vessels in the submandibular gland. Results Submandibular sialoadenectomy were successfully performed in 8 cases. The operative time was 45-75 minutes (mean, 60 minutes). All incisions obtained heal ing by first intention. No nerve paralysis occurred, including marginal mandibular branch of the facial nerve, the l ingual nerve, and hypoglossal nerve. One patient had poor blood circulation of flap due to excessive traction during operation, but it returned normal after 24 hours without special treatment. Other flaps had good blood circulation. All patients were followed up 1-6 months (mean, 3 months). The incision scars were hidden with satisfactory appearance. Conclusion The modified retroauricular approach has some advantages such as simple operation, better cosmetic outcome, and no compl ication.
Objective To analyze the use of modified pericardial oblique sinus approach in surgical repair for total anomalous pulmonary venous connection in neonates. Methods Between May 2005 and December 2015, 67 consecutive neonates with supracardiac or infracardiac type total anomalous pulmonary venous connection who underwent surgical repair in our institute were included in this study. The patients are divided into three groups according to the different approaches including a sulcus approach group (6 patients), a superior approach group (14 patients), and a modified pericardial oblique sinus approach group (47 patients). There were 53 males and 14 females at median age of 12.5 (7.0, 20.5) d.

Perioperative mortality (2.1% vs. 28.6%, P<0.05) was significantly lower in the modified pericardial oblique sinus approach group than that in the superior approach group. The long-term mortality (4.3% vs. 60.0%, P<0.05) was significantly lower in the modified pericardial oblique sinus approach group than that in the sulcus approach group or the superior approach group . The rate of pulmonary venous stenosis was significantly lower in the modified pericardial oblique sinus approach group than that in the sulcus approach group (2.1% vs. 50.0%, P<0.05) or superior approach group (2.1% vs. 35.7%, P<0.05). Conclusions In surgical correction of neonatal supracardiac and infracardiac total anomalous pulmonary venous, compared with the traditional surgical approach, the modified pericardial oblique sinus pathway can provide excellent surgical space and has a good surgical prognosis.
ObjectiveTo investigate the effectiveness of modified tibial transverse bone transport technique combined with vancomycin calcium phosphate bone cement local filling and covering in the treatment of diabetic foot (DF). MethodsThe clinical data of 22 DF patients treated with modified tibial transverse bone transport technique combined with vancomycin calcium phosphate bone cement local filling and covering between October 2019 and December 2021 were retrospectively analyzed. There were 13 males and 9 females with an average age of 61.3 years (range, 41-74 years). The duration of diabetes mellitus was 8-30 years, with an average of 12.5 years, and the duration of DF was 10-42 days, with an average of 28.2 days. There were 2 cases of grade 3 and 20 cases of grade 4 according to Wagner classification. CT angiography was performed on both lower extremities of the patients, and the blood vessels of the affected extremities were narrowed to varying degrees and the blood supply was poor. The preoperative skin temperature of affected foot was (28.27±0.91)°C, the ankle brachial index (ABI) was 0.42±0.11, and the visual analogue scale (VAS) score was 7.7±0.6. Preoperative size of DF ulcer ranged from 2.5 cm×2.0 cm to 3.5 cm×3.0 cm. The skin temperature of affected foot, ABI, VAS score, and skin wound healing of the affected foot were recorded and compared between before operation and at 3 months after operation. ResultsAll patients were followed up 3-18 months, with an average of 10.5 months. The infection of 1 patient with Wagner grade 4 did not improve significantly after operation, and there was a trend of further deterioration, and the amputation of the left leg was finally performed at 22 days after operation.The remaining 21 patients recovered well after operation, the external fixator was removed at 1 month after operation, the wound healed at 3 months after operation, and there was no recurrence of ulcer in situ or other sites during follow-up. At 3 months after operation, the skin temperature of affected foot was (31.76±0.34)°C, the ABI was 0.94±0.08, and the VAS score was 2.1±0.3, which significantly improved when compared with those before operation (t=25.060, P<0.001; t=32.412, P<0.001; t=–51.746, P<0.001). ConclusionModified tibial transverse bone transport technique combined with vancomycin calcium phosphate bone cement local filling and covering for DF patients can effectively improve the blood supply of the affected limb, promote wound healing, and improve effectiveness.
Objective To explore the effect of early weight-bearing exercise on the recovery of elderly patients with intertrochanteric fractures after internal fixation. Methods The clinical data of 50 patients with unstable intertrochanteric fractures (AO 31-A2 or A3) who underwent proximal femoral nail treatment between February and August 2015 were collected. Among them, 25 patients underwent early weight-bearing exercise after surgery (the observation group), and 25 patients underwent routine recovery after surgery (the control group). Demographic data of patients, modified Barthel Index, and EuroQOL Five Dimensions Questionnaire (EQ-5D) scores were collected, and mortality was assessed by telephone follow-up one year after surgery. Results In the observation group, the modified Barthel Index before injury, within 48 hours , 6 weeks , 12 weeks, and 1 year after surgery was 49.56±2.00, 26.40±3.11, 44.04±3.92, 47.92±3.13, and 48.76±3.07, respectively; in the control group, the modified Barthel Index at the above mentioned time points was 49.92±0.40, 26.52±3.34, 40.92±2.62, 45.44±2.36, and 49.16±1.75, respectively. The difference between the observation group and the control group at 6 and 12 weeks after surgery was a statistically significant (P<0.05), and the observation group was better than the control group; there was no statistical difference between the two groups in the modified Barthel Index before surgery, within 48 hours after surgery or one year after surgery (P>0.05). None of the patients died within the first one year after surgery. Conclusion The early weight-bearing exercise after hip fracture in the elderly has a positive effect on the recovery of the patients.
Eight patients treated with modified radical mastectomy and fenestration of pectoralis muscle to preserve pectoral, nerves are reported and the practical procedure is introduced. The results indicate that this method can overcome the disadvantage of mastectomy (Auchincloss) in that only dissection of fatty tissue and lymph nodes in the lateral part of axilla is carried out. With fenestration of pectoralis major muscle, not only the pectoral nerves can be perserved but also the fatty tissue and lymph nodes, including of those medial to the pectoralis minor, subclavicular and interpectoral nodes can be dissected. This method almost reached Halsted’s demand and it can be used for stage Ⅰ-Ⅱ, and even stage Ⅲ breast cancer if no infiltration to pectoralis major muscle is found.
