ABSTRACT

Osteochondral lesion of talus (OLT) is a foot and ankle disease characterized by ankle pain, which may impact the joint function and life quality. If managed improperly, it may lead to a further ankle arthritis, severely compromising the prognosis. The therapeutic effect of conservative treatment for OLT is still uncertain. Surgery is still the main treatment modality for OLT with various techniques. However, the optimized surgical technique is still inconclusive, furthermore, regeneration and repair of cartilage after debridement is also a great challenge for the treatment of OLT. Platelet-rich plasma (PRP) with good repair effect on cartilage injury is gradually applied in the treatment of OLT. However, there still lacks the unified understanding of the technique and specification of PRP for the treatment of OLT. Therefore, National Orthopedics Center of Shanghai Sixth People′s Hospital allied Foot Ankle Basic Research & Orthopedics Group, Chinese Association of Orthopedic Surgeons; Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians; and Foot and Ankle Group of Orthopedic Specialized Branch of Shanghai Medical Association to organize related experts to formulate the Expert consensus on platelet- rich plasma treatment for osteochondral lesion of talus ( version2023). Fifteen recommendations were put forward upon PRP preparation, indications, contraindications and treatment methods of PRP for OLT, so as to standardize the PRP treatment for OLT.

ABSTRACT

Objective To analyze the risk factors for the occurrence of post transplantation diabetes mellitus (PTDM) in renal transplant recipients, establish a prediction model for PTDM and evaluate its prediction value. Methods Clinical data of 915 renal transplant recipients were retrospectively analyzed. According to the occurrence of PTDM, all recipients were divided into the PTDM group (n=78) and non-PTDM group (n=837). The main indexes of recipients were collected. The risk factors for the occurrence of PTDM in renal transplant recipients were analyzed by univariate and multivariate analysis. The prediction model for PTDM was established and its prediction value was evaluated. Results Family history of diabetes mellitus, body mass index (BMI), preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin were the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM was logit (P)=2.199×family history of diabetes (yes=1, no=0)+0.109×BMI+0.151×2 h postprandial blood glucose (mmol/L)+0.508×glycosylated hemoglobin (%)-9.123. The results of receiver operating characteristic (ROC) curve showed that the area under the curve (AUC) of these 4 predictors combined for predicting PTDM in renal transplant recipients was 0.830 [95% confidence interval (CI) 0.786-0.873], the cut-off value was 0.0608, the sensitivity was 0.821, the specificity was 0.700, and the Youden index was 0.521 (P < 0.05). Conclusions Family history of diabetes mellitus, BMI, preoperative 2 h postprandial blood glucose and preoperative glycosylated hemoglobin are the independent risk factors for the occurrence of PTDM in renal transplant recipients. The prediction model for PTDM combined with4 predictors yield relatively high prediction value for PTDM.

ABSTRACT

Objective:To explore the clinical effects of arthroscopic treatment of intraarticular displaced fractures of the calcaneus in children.Methods:The clinical data were analyzed retrospectively of the 11 children who had been treated for intraarticular displaced fractures of the calcaneus at Department of Orthopaedics, The Affiliated Hospital of Southwest Medical University from January 2015 to June 2018. They were 6 boys and 5 girls, aged from 8 to 12 years (average, 10.6 years) and involving the left foot in 7 cases and the right foot in 4. By the Sanders classification, there were 10 cases of type Ⅱ and one of type Ⅲ. Preoperative evaluation of the injury was conducted by X-ray examination and three-dimensional CT reconstruction of the calcaneus. After arthroscopic prying reduction, internal fixation with mere Kirschner wire was performed for 8 cases and internal fixation with Kirschner wire plus hollow screws for 3. The affected feet were fixated with plaster bracket or brace for one month after operation. The Kirschner wires were removed 4 to 6 weeks after operation when X-ray films revealed fracture union. The clinical effects were evaluated by anatomic recovery of the calcaneus in terms of preoperative and postoperative B?hler and Gissane angles and functional recovery of the calcaneus in terms of ankle-hindfoot scores of American Orthopedic Foot Ankle Society (AOFAS) scale.Results:All the 11 pediatric patients were followed up for 12 to 19 months (average, 14 months). No bone grafting was applied. Their operation time averaged 63 min (from 50 to 75 min). Their incisions healed at one stage without infection. All their fractures healed within 2 to 3 months without any delayed union or nonunion. The B?hler angle (28.4°±2.9°) and Gissane angle (125.6°±3.1°) at the final follow-up were significantly improved than the preoperative values (11.8°±5.4° and 138.8°±6.3°) ( P< 0.05). The AOFAS ankle-hindfoot scores were 89.6 points at the final follow-up. Conclusion:Arthroscopic percutaneous prying reduction combined with internal fixation with Kirschner wire and hollow screws can effectively reduce and fixate the intraarticular displaced fracture of the calcaneus in children, leading to limited surgical trauma and fine curative effects.

There were 11 males and 7 females from 39 to 76 years old, with an average age of 53.4 years. Preoperative diagnoses included traumatic arthritis (3 cases), osteoarthritis (10 cas-es), talar necrosis (3 cases), failure of ankle fusion (1 case) and Charcot-Marie-Tooth disease (1 case). Ankle and hindfoot deformi-ty included varus (10 cases), valgus (6 cases), equinus (1 case) and equinovarus (1 case). All cases were classified into stage-3 ar-thritis according to Morrey-Wiedeman classification. All patients sustained pain and stiffness in the ankle and hindfoot as well as walking dysfunction. Preoperative and 1 year postoperative visual analogue scale (VAS) and American Orthopaedic Foot and An-kle Society (AOFAS) ankle-hindfoot scale were collected. Postoperative joint fusion and complications were observed.@*Results@#Follow-up ranged from 12-47 months, averaging 25.4 months. Preoperative VAS scores were 6-9, averaging 7.1±1.0, while postop-erative VAS scores at 1 year follow-up were 0-2, averaging 0.9±0.8, which decreased significantly. Preoperative AOFAS scores were 24-59, averaging 40.6±11.5, while postoperative AOFAS scores at 1 year follow-up were 68-84, averaging 75.3±5.8, which increased significantly. 8 cases were good and 10 cases were fair according to AOFAS scores at 1 year follow-up. The excellent and good rate was 44.4% (8/18). All joints were fused successfully without implants loosening or breakage. All patients satisfied with operative results at 1 year follow-up. Lateral distal wound dehiscence happened in 1 case of traumatic arthritis and the wound was finally healed after debridement and vacuum assisted closure (VAC). Two cases of osteoarthritis presented with dorsal lateral foot numbness and became asymptomatic after neurotrophic medication. One case of osteoarthritis complained of discomfort in the lateral heel caused by implants prominence and implants were removed at 1 year after surgery. Postoperative complication rate was 22.2% (4/18) .@*Conclusion@#TTC via lateral transfibular approach with cannulated screws and locking plate system is safe and ef-fective.

ABSTRACT

Objective To investigate the learning curve of transesophageal echocardiography (TEE) applied in mechanically ventilated patients in intensive care unit (ICU).Methods A prospective observation study was conducted. A total of 60 consecutive patients necessary for mechanical ventilation and TEE examination admitted to the Department of Surgical ICU of the First Affiliated Hospital of Sun Yat-Sen University from December 2016 to June 2017 were enrolled. The TEE examination was performed by the same ICU physician who was skilled in transthoracic echocardiography (TTE). The TEE probe intubation (trial numbers of TEE intubation, the duration for a successful intubation at the first attempt, the total time for successful intubation), TEE examination (the scores of TEE examination, the duration of TEE examination), and the complication during examination were observed, with learning curve established. According to the date of examination, a statistical analysis was carried out for each group of 12 cases. Through the learning curve, that TEE examinations in how many cases should be performed by the ICU physician to master the skill was observed.Results With the increase of TEE examinations performed by the physician, the duration for a successful intubation at the first attempt and the total time for successful intubation were gradually reduced; the scores of TEE examination were gradually increased, and the duration of TEE examination gradually reduced. ① TEE intubation: there was no statistical significant difference among the 60 patients in the number of intubation attempts (F = 0.258,P = 0.904). After the SICU doctor completed TEE intubations in 12 cases, the duration for a successful intubation at the first attempt was significantly reduced (seconds: 22.24±18.37 vs. 34.88±1.65,P < 0.05) and then tended to stabilize in the 16 - 23 seconds. The learning curve indicated that the physician could basically master the intubation skills after performing TEE intubations in 24 cases. ② TEE examination: after the physician completed TEE intubations in 24 cases, the TEE examination scores were increased significantly (40.08±7.27 vs. 23.67±9.70,P < 0.05), and then tended to stabilize in the 40 - 47 scores; after TEE intubations were performed in 24 cases, the examination duration was significantly shortened (minutes: 39.97±6.67 vs. 58.22±14.19,P < 0.05), and after 36 cases were completed, the duration could be further shortened (minutes:31.04±7.84 vs. 39.97±6.67,P < 0.05). The learning curve indicated that the ICU physician could basically master the examination skills when TEE examinations were completed in 36 cases. In addition, no serious complications occurred during the TEE examination.Conclusions A SICU physician with skilled TTE experience can basically master the TEE technology through 36 times of examinations, and reach full mastery after 48 times, the duration for a successful intubation at the first attempt could be stabilized at 20 seconds, and the examination duration could be stabilized at 30 minutes.

ABSTRACT

Objective To compare 2 mini-invasive surgical treatments,Achillon versus sponge forceps,for acute Achilles tendon rupture.Methods Between December 2010 and January 2015,35 patients with acute Achilles tendon rupture were treated at our department.They were 32 males and 3 females,with an average age of 36.4 years (range,21 to 64 years).The interval between injury and operation was 1 to 13 days (average,3.2 days).Sixteen of them were treated by Achillon while 19 by sponge forceps.The 2 groups were compatible with no significant differences in general clinical data (P > 0.05).Rehabilitation was carried out 4 weeks after immobilization with brace.American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot scoring system was used to evaluate the function of the affected foot at the last follow-up.The 2 groups were compared in terms of surgery time,hospital stay,AOFAS score,decrease in leg circumference,complications and rerupture rate.Results All the patients were followed up for an average of 9.6 months (from 6 to 19 months).There were no significant differences between the Achillon and sponge forceps groups regarding average AOFAS score (91.8 ± 4.4 versus 93.2 ± 5.8),surgery time (38.3 ± 13.2 min versus 42.5 ± 9.8 min),hospital stay (3.9 ± 1.5 d versus 4.1 ± 1.6 d),or decrease in leg circumference (2.1 ±0.5 cm versus 2.3 ± 0.3 cm) (P > 0.05).No re-ruptures or sural nerve lesion was observed in either group.One case of delayed wound healing occurred in each group.Conclusions Both Achillon and sponge forceps can lead to limited complications and a very low rate of re-rupture in surgical treatment of acute Achilles tendon rupture.Compared with the Achillon technique,sponge forceps may have the advantages of simplicity and lower cost.

ABSTRACT

Objective:To investigate the characteristics and perioperative management of hemophilia patients with fracture.Methods:Retrospectively, we analyzed 8 patients with hemophilia combined with fracture, who were admittted to our department from 2005 to 2013.Six patients were with hemophilia A and two with hemophilia B;Based on the severity of hemophilia, 2 cases were light, 3 moderate and 3 severe;Based on the location of fracture, 4 cases were femoral neck fractures, 1 femoral intertrochanteric fracture, 1 bilateral distal femur fractures, 1 tibiofibula fracture, and 1 humerus intercondylar fracture. Blood coagulation factor replacement therapy was conducted preoperatively, intraoperatively and postoper-atively, All the patients underwent closed or open reduction and internal fixation or joint replacement. Also, we analyzed the perioperative complications and observed whether the fracture healed.Results:The average age was 33.5 years (14 to 47 years); In 6 cases, fractures occurred at femur, accounting for 75%of all the fractures; Femoral neck fracture was treated by closed reduction and hollow screws fixation;Femoral intertrochanteric fracture, distal femur fracture, and tibiofibula fracture were treated by open reduction and internal fixation with plate;Humerus intercondylar fracture was treated by elbow joint replacement.Intraoperative bleeding was from 50 to 600 mL, an average of 262 mL;Perioperatively, the average use of FⅧ/activated prothrombin complex concentrates ( APCC) was 358 U/kg (125 to 554 U/kg) .Postoperatively, poor wound healing was observed in 2 patients, and the condition improved after symptomatic treatment; In patients with internal fixation, all the fractures united, and the average hea ling time was 14 weeks.No complications such as fixation loosening or rupture occurred after internal fixation.Conclusion:Hemophilia combined with fracture mainly occurred in the young, and the site of fracture was given priority to femur.With perfect preoperative preparation, on the basis of the replace-ment therapy, hemophilia combined with fractures was safe for surgical treatment, and postoperative frac-tures healing wasgood.But the risk of poor wound healing was high.

ABSTRACT

<p><b>BACKGROUND</b>There are no unified theories as to the anatomical changes that occur with hallux valgus, we investigated the radiological characteristics and anatomical risk factors for hallux valgus deformity in Chinese adults.</p><p><b>METHODS</b>We reviewed 141 patients with hallux valgus (206 feet; 15 males, 126 females; mean age, 58.5 years). These patients attended Peking University People's Hospital from April 2008 to March 2014. All feet had intact radiological data, obtained using the Centricity RIS/PACS system. We measured hallux valgus angle (HVA), 1-2 intermetatarsal angle (IMA), proximal articular set angle (PASA), distal articular set angle, hallux interphalangeal angle, metatarsocuneiform angle, size of the medial eminence of the distal first metatarsal, tibial sesamoid position, and joint congruity of the first metatarsophalangeal joint (MTPJ).</p><p><b>RESULTS</b>We found positive correlations between the HVA and IMA (r = 0.279, P < 0.01) and HVA and PASA (r = 0.358, P < 0.01), but not for IMA and PASA (P > 0.05). Feet were divided into three groups based on HVA severity. IMA (P < 0.05) and PASA (P < 0.05) in the mild group were significantly lower than that in the moderate and severe groups, with no significant difference determined for IMA or PASA between the moderate and severe groups (P > 0.05). Feet were then grouped based on the shape of the first metatarsal head. Using this grouping, HVA was significant higher in the rounded shape (19.92°) than in a flat shape (17.66°). The size of the medial eminence of the distal first metatarsal was positively correlated with HVA (r = 0.185, P < 0.01). The medial eminence in the moderate and severe groups was significantly larger than that in the mild group; moderate and severe groups were not significantly different.</p><p><b>CONCLUSIONS</b>PASA enlargement is an adaptive change during early hallux valgus formation, and decompensation leads to subdislocation in the first MTPJ. A rounded first metatarsal head would thus predispose a foot to hallux valgus. Furthermore, bone proliferation at the medial eminence may also lead to early hallux valgus development.</p>
