Objective To evaluate the technique and clinical effect of arthroscopic treatment of anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique. Methods From May 2013 to July 2015, 18 patients with anterior cruciate ligament tibial eminence avulsion fracture were treated with arthroscopic re﹣duction and fixation by suture bridge technique. There were 12 males and 6 females with an average age of 29.8 years old (range, 9~45 years). The right knees were involved in 10 cases and left knees in 8 cases. The injury caus﹣es included traffic accident injury in 10 cases, sports injury in 5 cases and other reasons in 3 cases. 2 patients had old fracture, the others had fresh fracture. The results of Lachman and anterior drawer test were both positive. The International Knee Documentation Committee (IKDC) subject score was (53.8 ± 4.2). Based on Meyers-Mckeaver classification, there were 5 cases in typeⅡ, 10 cases in type Ⅲ and 3 cases in type Ⅳ. Results The operation time was 50~80 minutes (mean, 60.5 minutes), X-ray showed satisfactory fracture reduction after surgery. Primary healing of incision were obtained with no infection, all 18 patients were followed up for 6 ~ 31 months (mean, 18.6 months). The results of Lachman and anterior drawer test were both negative in 17 cases, the result was negative for anterior drawer test and was weakly positive for Lachamn test in 1 case. The IKDC subject score were significantly improved to (95.2 ± 3.8) at last follow-up (P< 0.05). Conclusion It could achieve early restoration of knee joint function to treat the anterior cruciate ligament tibial eminence avulsion fracture with suture bridge fixation technique because of satisfactory reduction, reliable fixation, minor trauma, and quick recovery.

Objective To investigate the prevalence of nutritional risk and undernutrition of geriatric patients with hip fracture in the department of orthopaedics and analyze the relationship between nutritional risk scores and clinical outcomes.Methods In this prospective cohort study,the baseline demographic data of 235 elderly patients with hip fracture in the department of orthopaedics of Ningbo First Hospital were consecutively recorded from November 2013 to December 2015.The prevalence of nutritional risk and undernutrition,infectious complications,and length of hospital stay were also recorded.The infectious complications and length of hospital stay in patients in different age groups(60-69 years,70-79 years,and ≥80 years)and those with different nutritional risks(<3 points,3-4 points,and ≥5 points)were analyzed.Results All patients without PN EN support during hospitalized durations.The incidence of nutritional risk was 62.98％in 235 elderly patients with hip fracture,twenty patients were undernutritioned by multi-item standard based on Nutritional Risk Screening 2002 nutrition disorder score,and 15 patients were undernutritioned by one-item standard with body mass index.Hip arthroplasty patients had significantly higher nutritional risk than those who had undergone internal fixation(74.04％vs.54.20％,P=0.002).Patients with comorbidities had significantly higher nutritional risk than patients without comorbidities(71.56％vs.55.56％,P=0.011).There were significant differences in infectious complications(2.30％vs.3.91％vs.50.00％)and length of hospital stay[(6.35±0.87)d vs.(8.12±1.13)d vs.(10.85±1.52)d,(8.66±2.06)d vs.(10.45±2.43)d vs.(13.25 ±3.65)d] among patients with different nutritional risks(<3 points,3-4 points,and ≥5 points)(P=0.000).Conclusions Elderly patients with hip fracture has relatatively high nutritional risk.These patients tend to have more complications and longer hospital stay.

Objective? To explore the effects of enhanced recovery after surgery based on nutritional support in perioperative nursing of elderly patients with hip fracture and joint replacement. Methods? From January 2015 to June 2017, we selected 278 elderly hip fracture patients with nutritional risk (NRS 2002≥3) by convenience sampling. All of the patients were divided into observation group (n=132) and control group (n=146) with the method of envelope. Observation group accepted nutritional support and brought it into enhanced recovery nursing process. Control group applied routine perioperative nursing without standardized nutritional support. We compared the albumin and loss of hemoglobin at the second day after surgery, the score of activity of daily living (ADL), time of getting out from bed for the first time, hospital stay as well as complications of patients between two groups. Results? The albumin at the second day after surgery and score of ADL of patients in observation group were (29.16±1.33) g/dl and (63.90±5.47) respectively higher than those in control group;the loss of hemoglobin after surgery, time of getting out from bed for the first time, hospital stay in observation group were (1.34±0.30) g/dl, (1.56±0.20)d, (7.08±2.23)d respectively lower than those in control group;the differences were all statistical (t=-3.089, -14.881, -13.640, -15.279, -8.480;P＜0.05). The incidence of complications of observation group was 9.09% lower than that of control group (19.18%) with statistical difference (χ2=3.877, P＜0.05). Conclusions? Enhanced recovery nursing based on nutritional support can shorten the hospital stay in elderly patients with hip fracture, promote postoperative rehabilitation after hip joint replacement and improve clinical outcomes of patients.

Objective To explore the influence factors for femoral head necrosis after treatment of femoral neck fractures with dynamic hip screw (DHS) and anti-rotation screw.Methods A retrospective case series analysis was made on the clinical data of 106 cases of femoral neck fractures who had undergone fixation with DHS and anti-rotation screw between May 2010 and May 2015.There were 59 males and 47 females,with an average age of 57.0 years (range,27-76 years).By Garden classification,there were 27 cases of type Ⅱ,51 cases of type Ⅲ and 28 cases of type Ⅳ.All cases were divided into femoral head necrosis group (18 cases) and none-necrosis group (88 cases) according to the radiographs of the fractured hip at the follow-up.Univariate analyses and a multivariate logistic regression analysis were made to test whether the following factors were significantly associated with femoral neck necrosis:sex,age,Garden classification,Pauwels classification,Singh index,injury-to-surgery time interval,reduction methods,reduction quality,complete weight-bearing time,implant removal and the time cost of implant removal surgery.Results All the 106 patients obtained a mean follow-up of 49 months (range,26-76 months).Femoral head necrosis occurred in 18 cases (17.0％).In univariate analyses,Garden classification,reduction quality,implant removal and long time of the implant removal surgery were significantly associated with femoral head necrosis (P ＜ 0.01).In multivariate logistic regression analysis,high level of Garden classification(95％ CI 0.008,0.998,P ＜ 0.05),implant removal and long time of the implant removal surgery (95％ CI 0.000,0.143,P ＜ 0.01) were found to have a significant effect on femoral head necrosis development.Conclusions Fracture displacement,removal of internal fixation and broadening the screw canal,which cand hinder the blood supply of femoral head,will enhance the rate of femoral head necrosis.As a result,it needs prudent consideration to remove internal fixation after internal fixation with DHS combined with anti-rotation screw for femoral neck fractures.When it is difficult to remove the anti-rotation screw,it is better to give up,rather than to force a removal.

Objective To investigate the current status of perioperative nutritional risk and nutritional intake in aged patients with hip fracture, so as to provide references for standard nutritional support. Methods A prospective cohort study was designed. 235 patients with hip fracture admitted in the Orthopedics Department of Ningbo First Hospital from November 2013 to December 2015 were selected and investigated by nutritional risk screening 2002 ( NRS-2002 ) , to assess the nutritional risk of patients with hip fracture and collect their nutritional intake situation. Results The nutritional risk of 235 patients with hip fracture was 63. 40%, which was higher than that of patients without hip fracture (χ2=37.445,P<0.05), and it was also higher than that of patients with other kinds of fracture ( P<0. 05 ) . Single factor analysis showed that, the perioperative nutritional risk of aged patients with hip fracture was influenced by surgical procedures (χ2 =9. 093,P<0.05) . 235 aged patients with hip fracture were given daily foods in the perioperative period, and the intake of protein and calories were lower than the standard recommended in guideline. Conclusions The nutritional risk in aged patients with hip fracture is high, and the nutritional support was not enough, which should be paid attention by clinical medical workers.
