Objective:To evaluate the clinical outcomes of Chaput tuberosity osteotomy and lateral malleolus sagittal osteotomy in the treatment of talus osteochondral lesions with autologous osteochondral transplantation (AOT).Methods:From January 2017 to December 2019, Chaput tuberosity osteotomy and lateral malleolus sagittal osteotomy were performed in the AOT treatment of 11 patients with talus osteochondral lesions. They were 9 men 2 women, with a mean age of 32. 6 years (range, from 22 to 45 years). Their lesions were all Hepple type V. Their American Orthopaedic Foot and Ankle Society (AOFAS) score, visual analogue scale (VAS), International Knee Documentation Committee Knee Evaluation Form (IKDC) score, and imaging data were measured pre- and post-operatively for assessment of clinical outcomes.Results:All the patients were followed up for 13 to 24 months (average, 15.6 months). Their AOFAS (94.3±2.9) and VAS (1.2±0.4) scores at the final follow-up were significantly improved compared with the pre-operative values (49.5±6.6 and 5.7±1.2) ( P<0.05). There was no significant difference between their pre- and post-operative IKDC scores for the ipsilateral knee joint ( P>0.05). The imaging showed that the talus cystic change disappeared and the grafted bone was fully fused with the talus with no abnormal change in the joint space. Conclusion:In the AOT treatment of talus osteochondral lesions, Chaput tuberosity osteotomy and lateral malleolus sagittal osteotomy can obviously relieve ankle pain and improve ankle function.

BACKGROUND:Accurate reduction of ankle fractures under direct vision has become a common understanding among foot and ankle surgeons.How to fully expose free or compressed fragments of the posterior ankle remains one of the most challenging problems. OBJECTIVE:To explore the clinical efficiency of the para-Achilles tendon approach in exposing and repositioning the posterior malleolus sandwich fracture. METHODS:A retrospective study was made for 26 patients with posterior malleolus sandwich fracture treated with open reduction and internal fixation via para-Achilles tendon approach from January to December 2020 in The Second People's Hospital of Dalian.21 of 26 cases were managed with the lateral approach of Achilles tendon and 5 cases were managed with the medial approach of Achilles tendon.There were 19 males and 7 females,with the age of 24-69 years,averagely 38.6 years.The operation time and postoperative complications were recorded.The fracture reduction condition was evaluated by Burwell-Charnley imaging standard.Before operation,3 months after operation and last follow-up,visual analog scale score,ankle plantar flexion and dorsiflexion and American Orthopedic Foot&Ankle Society Ankle Hind Score were used to evaluate the treatment effect. RESULTS AND CONCLUSION:(1)All 26 patients were followed up for an average of 14.6 months(range 13-18 months).The operation time was 52-85 minutes(average 64.2 minutes).(2)Part of the skin edge of the lateral malleolus incision was necrotic in one patient and healed completely after a dressing change.Incision healing of the other patients was in one stage.(3)Through Burwell-Charnley imaging standard,anatomical reductions were obtained in 24 of 26,and good reductions were in 2 of 26,with an excellent and good rate of 100%.(4)At the last follow-up,the visual analog scale score(1.19±0.40)was significantly lower than the preoperative score(6.81±0.80)(P<0.01).Ankle plantar flexion(33.5±5.02)° and ankle plantar back stretch(17.23±0.99)° were significantly increased compared with preoperative data(14.58±2.50)° and(5.81±1.02)°(P<0.01).American Orthopedic Foot&Ankle Society Ankle Hind Score was improved to(89.31±3.62)points compared to preoperative(46.00±5.45)points(P<0.01).The results were excellent in 23 patients and good in 3 patients,with an excellent and good rate of 100%.(5)It is concluded that the open reduction and internal fixation via the para-Achilles tendon approach for the treatment of posterior malleolus sandwich fracture were efficient with decreased operation time,satisfying fracture reduction,fewer complications,satisfactory motion range,and functional recovery.

Objective:
To identify the associated factors of peripheral blood lymphocyte counts (PBLC) in gastric cancer patients
Methods:
In this cross⁃sectional study , data were collected from patients underwent gastric cancer surgery. Univariate analysis , multiple linear regression and variable importance metrics were used to assess factors associating PBLC in pre⁃operative patients. The findings were further investigated by fitting locally weighted regression(loess) and robust linear model (rlm) .
Results:
Patients with pre⁃operative PBLC < 1 . 1 × 109/L( group A) were 138(20. 72% ) , whereas patients with PBLC ≥ 1. 1 × 109/L ( group B) were 528(79. 28% ) . Compared to group B , patients in group A were older[(64. 61 ± 10. 42 years) vs (62. 18 ± 10. 41 years) , P < 0. 05 ] and showed lower neutrophils [(3. 21 ± 1. 41) × 109/L vs (3. 59 ± 1. 31) × 109/L , P < 0. 01] . Lymphopenia was associated with later stage of gastric cancer, P < 0. 01 . A multiple linear regression model with randomly distributed residuals found that age ( β = - 0. 01 , t = - 3. 70 , P < 0. 01) and tumor stage [ β ( Ⅱ vs Ⅰ ) = - 0. 16 , t =- 2. 79 , P < 0. 01 ; β ( Ⅲ vs Ⅰ ) = - 0. 18 , t = - 3. 86 , P < 0. 01 ; β ( Ⅳ vs Ⅰ ) = - 0. 21 , t = - 2. 16 , P <0. 05] were to be statistically significant factors for lymphopenia. Neutrophil increase (β = 0. 05 , t = 3. 61 , P < 0. 01) was associated with a higher PBLC. The relative importance analysis for continuous independent variables showed that relative importance metric LMGs in variable age , neutrophil and CEA were 55. 55% , 44. 14% and 0. 31% respectively. Loess and rlm models showed that age was the negatively influencing factor of PBLC.
Conclusion
PBLC in gastric cancer patients were positively associated with neutrophils , and negatively associated with age and tumor stages.
