Correlation analysis of serum MMP-1 and MMP-2 levels with lower extremity deep venous thrombosis after operation for lower limb fracture / 中国骨伤

OBJECTIVE@#To investigate the relationship between serum matrix metalloproteinase-1(MMP-1) and matrix metalloproteinase-2(MMP-2) and the formation of deep venous thrombosis(LDVT) in lower extremity patients after surgery for lower extremity fracture, and to analyze the value of MMP-1 and MMP-2 in predicting the occurrence of LDVT after lower extremity fracture.@*METHODS@#From June 2018 to December 2021, 352 patients who planned to receive surgical treatment of lower limb fracture in our hospital were selected as the research objects. Venous blood was collected at 1, 2 and 3 days after surgery, respectively, and serum MMP-1 and MMP-2 levels were detected. The incidence of LDVT during hospitalization was analyzed, and the risk factors of postoperative LDVT in patients with lower limb fracture surgery and the predictive value of MMP-1 and MMP-2 for LDVT were analyzed.@*RESULTS@#LDVT occurred in 40 patients (LDVT group), the incidence of LDVT was 11.36%, and 312 patients did not occurred(no occurred group). The serum levels of MMP-1 and MMP-2 in LDVT group increased gradually after surgery; the serum levels of MMP-1 and MMP-2 in the no occurred group increased slightly after surgery at 2 days and then decreased at 3 days after surgery (P<0.01);the serum levels of MMP-1 and MMP-2 in LDVT group were higher than those in the no occurred group at 2 days and 3 days after surgery (P<0.05). Serum levels of MMP-1 and MMP-2 were positively correlated with serum levels of interleukin-6 (IL-6), IL-8 and tumor necrosis factor -α (TNF-α) in LDVT patients at 2 days and 3 days postoperatively (P<0.05). Operative time, MMP-1 and MMP-2 postoperative 3 days were related to the occurrence of LDVT after lower limb fracture (P<0.01). The area under the curve(AUC) predicted by MMP-1 and MMP-2 postoperative 3 days for LDVT after lower limb fracture was 0.738 and 0.744 respectively, and the AUC predicted by combined MMP-1 and MMP-2 was 0.910, which was higher than that predicted by single indicator(Z=2.819 and 2.025, P<0.05).@*CONCLUSION@#High levels of MMP-1 and MMP-2 after lower extremity fracture are closely related to the occurrence of LDVT, and 3 d mMP-1 and MMP-2 after surgery maybe used as evaluation indexes for LDVT risk prediction.

Survivorship and Complications after Hip Fracture Surgery in Patients with Chronic Kidney Disease

The aim of this study was to investigate survival rate, complications and associated risk factors after hip fracture surgery in patients with chronic kidney disease (CKD) by comparing to non-CKD patients. A total of 119 patients (130 hips, 63 hips CKD group, 67 hips non-CKD) who underwent hip fracture surgery were included. We assessed variables including age, gender, CKD, comorbidities, operation delay and operation time as risk factors for survival and complications after hip fracture surgery. The survival rate was 55.8% at 1-year, 45.8% at 3-year, and 31.4% at 5-year in CKD group, whereas 82.1%, 60.7%, and 36.8%, respectively in non-CKD. Age (more than 85) (hazard ratio [HR], 3.238; 95% confidence interval [CI], 1.736–6.042; P < 0.001), stages 4, 5 of CKD (HR, 2.004; 95% CI, 1.170–3.433; P = 0.001), cerebrovascular disease (HR, 2.213; 95% CI, 1.196–4.095; P = 0.001), and malignancy (HR, 3.086; 95% CI, 1.553–6.129; P = 0.001) were significant risk factors. Complications occurred in 17 hips of CKD group and 8 hips of non-CKD. Stage 4–5 of CKD (odds ratio [OR], 3.401; 95% CI, 1.354–8.540; P = 0.001), malignancy (OR, 3.184; 95% CI, 0.984–10.301; P = 0.050) were significant risk factor. When performing hip fracture surgery in patients with CKD, surgeons should consider age, severity of CKD, and presence of other comorbid disease, such as cerebrovascular disease and malignancy, as patients with these risk factors will need more intensive preoperative and postoperative care.

OBJECTIVE:To observe analgesic effect and safety of ketorolac tromethamine combined with butorphanol tartrate in the treatment of acute pain after fracture surgery. METHODS:76 acute pain patients after fracture surgery were selected and ran-domly divided into control group and observation group,with 38 cases in each group. Control group was given Ketorolac trometh-amine injection 30 mg,ivgtt,and then 2 ml/h,0.5 mg/kg,ivgtt;observation group was additionally given butorphanol tartrate 10 mg,ivgtt,on the basis of control group. Pain degree was evaluated with VAS before and 10 min,1,2,4 and 6 h after treatment, and the occurrence of ADR was observed in 2 groups. RESULTS:10 min,1,2,4 and 6 h after treatment,VAS score of 2 groups were significantly lower than before,with statistical significance(P0.05). The incidence of ADR in observation group (5.26%)was significantly lower than in control group(21.05%),with statistical significance(P<0.05). CONCLUSIONS:Com-pared with ketorolac tromethamine alone,ketorolac tromethamine combined with butorphanol tartrate shows shorter analgesia dura-tion,similar therapeutic efficacy,and lower incidence of ADR.

Analysis of Risk Factors for Complication after Hip Fracture Surgery in the Elderly According to Geriatric Interdisciplinary Team Care and Orthopedic Care

PURPOSE: The study was to analyze clinical outcomes and risk factors of for complications associated with the hip fracture surgery in the elderly before and after interdisciplinary treatment. METHODS: A retrospective method was used to investigate the general and therapeutic characteristics, frequency of complications and clinical outcomes. The subjects of the study were 553 patients who underwent hip fracture surgery from January, 2009 to December, 2014. RESULTS: The interdisciplinary group was older and less likely to walk independently even before the fracture than a usual care group. The incidence of complications was higher in the interdisciplinary group than the usual care group. The prevalence of complications in both groups was 66.5%. Multivariate logistic regression analysis showsed that the risk factors for complications of hip fracture surgery were as follows: advanced age, stroke, Parkinson disease, time interval from emergency room to operation, pre & post ambulatory status, American Society of Anesthesiologists (ASA) classification quality of postop intensive care unit (ICU) care and foley indwelling. CONCLUSION: This study has implications in that it recognized the necessity for interdisciplinary treatment and provided the basic base data for nursing intervention of the elderly patients who underwent hip fracture surgery.

Incidence of Deep Vein Thrombosis after Major Lower Limb Orthopedic Surgery: Analysis of a Nationwide Claim Registry

PURPOSE: We aimed to evaluate the nationwide incidence and risk factors for symptomatic deep vein thrombosis (DVT) after major lower limb orthopedic surgeries. MATERIALS AND METHODS: The Korean Health Insurance Review and Assessment Service database was used to retrospectively identify International Classification of Disease-10 codes for DVT and operation codes representing hip arthroplasty, knee arthroplasty, and hip fracture surgeries. The age- and gender-adjusted annual incidence of DVT, rates of major lower limb orthopedic surgeries, and the postoperative incidence of DVT according to the surgical procedure were assessed. RESULTS: The age- and gender-adjusted annual incidence of DVT was 70.67 per 100000 persons/year. Compared to patients aged 70 years (p<0.001). Females showed a greater relative risk for DVT than males (1.08; p<0.001). The incidence of postoperative DVT, according to the type of surgery, was significantly greater for knee replacement arthroplasty than for other forms of surgery (p<0.002). The relative risk of postoperative DVT was higher in females in knee replacement arthroplasty (1.47) and hip fracture surgery (2.25) groups, although relatively lower in those who underwent hip replacement arthroplasty (0.97). CONCLUSION: Among major lower limb surgeries, advanced age, female gender, and undergoing a knee replacement arthroplasty were found to be risk factors for developing postoperative DVT. These findings further emphasize the need for orthopedic surgeons to consider the development of DVT after surgery in high-risk patients.

Perforation of Surgical Gloves during Lower Extremity Fracture Surgery and Hip Joint Replacement Surgery / 대한고관절학회지

PURPOSE: To assess the frequencies and sites of surgical glove perforations in lower extremity fracture surgery and hip joint replacement (HJR) surgery. Additionally, we also studied the usefulness of an indicator system glove. MATERIALS AND METHODS: We assessed surgical glove perforations in 30 cases of lower extremity fracture surgery and 18 cases of HJR surgery conducted by one right handed 1st operator from April 2013 to July 2013. We assessed frequencies and sites of perforation in 152 gloves; 95 used in lower extremity fracture surgery and 57 used in HJR surgery. We studied the perforation rates and sites according to participants and operation types. Using the Biogel indicator system glove, which is well known as a fast indicator of glove perforation, we were also able to assess the time difference between operative participant detection of perforation and inspector nurse detection while observing in the operative field. RESULTS: There were 18 of 30 cases in lower extremity fracture surgeries and 12 of 18 cases in HJR surgeries which had more than one surgical glove perforation event. Of all 152 gloves used, perforation occurred in 15 of 57 gloves (26.3%) in HJR surgery and 23 of 95 gloves (24.2%) in lower extremity fracture surgery. Perforation occurred more frequently in operators than assistant doctors or scrub nurses. The most frequent perforation site was the second digit of the left hand. On average, the time difference between operative participant notice of perforation and inspector nurse notice of perforation was 20.6 seconds. CONCLUSION: The perforation of surgical gloves happened in approximately one out of every four persons. Importantly, we noted a 37.0% prevalence of glove perforation in 1st operators. Considering that glove perforation is a critical factor responsible for intra-operative infection, surgeons must be conscious of the risk of surgical glove perforation and use double gloving regularly. Furthermore, indicator double gloving is recommended for fast detection of outer glove perforation.

Does Venous Thromboembolism Affect Rehabilitation after Hip Fracture Surgery?

PURPOSE: Venous thromboembolism (VTE), including deep vein thrombosis and pulmonary embolism, is a serious and life-threatening complication in elderly (older than 65 years) patients undergoing hip fracture surgery (HFS). However, few have reported on the influences of VTE on postoperative rehabilitation in these patients. This study was performed to determine whether VTE affects clinical outcomes in patients who underwent HFS. MATERIALS AND METHODS: We retrospectively evaluated 330 HFSs in 325 consecutive patients, which were performed from January 2009 to June 2010. From chart review, we identified 15 patients with symptomatic VTE. We compared Geriatric depression scale, Modified Barthel index and Berg balance scale scores as well as 10 meter gait speed at discharge and hospital stay between a symptomatic VTE group and a non-VTE group. RESULTS: No significant difference in clinical outcomes at discharge between the two groups was found, although hospital stay was longer in patients with symptomatic VTE (p=0.012). CONCLUSION: East Asian patients have a low incidence of symptomatic VTE after HFS, and the clinical outcomes of patients with symptomatic VTE were similar to patients without VTE, although there was a longer rehabilitation period.

Fracture of the acromion and arterial injury are a rare association. The clinical picture is characterized by shoulder pain, functional disability and swelling of the affected limb with decreased distal pulse and temperature. Radiography of the shoulder and arteriography define the diagnosis and assist in postoperative follow-up. The authors report a rare case of fracture of the acromion associated with injury of the ipsilateral ulnar artery and describe its treatment, as well as pre- and postoperative evaluations.

Radiation Exposure to the Orthopaedic Surgeon during Fracture Surgery / 대한정형외과학회잡지

PURPOSE: To assess the risk of radiation exposure by measuring the equivalent dose during fracture surgery. MATERIALS AND METHODS: Two orthopedic trauma surgeons were enrolled in this study from April to June 2009. The equivalent dose was measured using thermoluminiscent dosimeters placed at the left (in and out of the lead apron). RESULTS: The equivalent dose measured from the apron over the 3 month period were 5.22 mSv, 4.34 mSv(outside), and 1.83 mSv and 0.71 mSv(inside). The rate of radiation reduction was 64.9% and 83.6% respectively. CONCLUSION: The estimated annual equivalent dose outside the apron was close to or higher than the maximum limit of radiation exposure. These findings highlight the need for surgeons to be more cautious about radiation exposure during fracture management and take active steps to minimize radiation exposure, such as wearing a radio-protective apron.

[Objective]To investigate the clinical curative effect and superiority of subtotal corpectomy through the pedicle,titanium rete support and pedicle screws system fixation in the treatment of burst fracture of thoracic vertebrae with paralysis.[Method]Twenty-three patients who suffered from the burst fracture of thoracic vertebrae with paralysis were treated with subtotal corpectomy through pedicle,titanium rete supporting bone autograft and pedicle screws system fixation.[Result]The patients were followed up for 8 months to 2 years.All had their bone grafts fused,and no incision infection,pneumothorax,hemothorax,pulmonary infection,internal fixation loosening or breakage occurred.The mean loss of Cobb's angle was 3.5?.According to Frankel grading,6 of grade A had no obvious recovery.In 5 of grade B,3 improved to C,1 to D,and the last one to E.In 7 of grade C,3 improved to D,4 to E.Five cases of grade D improved to E.[Conclusion]There had relatively less operation wound and good clinical curative effect with subtotal corpectomy through pedicle,titanium rete supporting bone autograft and pedicle screws system fixation.

Surgical repair of medial orbital wall combined with orbital floor fracture via lower lid subciliary approach / 眼科

Objective To assess the effect of surgical repair of medial orbital wall combined with orbital floor fracture via lower lid subciliary approach. Design Retrospective case series. Participants 18 cases of medial orbital wall combined with orbital floor fracture. Methods All patients underwent the reconstruction of orbital wall via lower lid subciliary approach. The composite hydroxyapatite was implanted into the surface of medial orbital wall and orbital floor after lacriminal cyst was completely dissected and protected during the operation. Orbital axial and coronal CT, three-dimension CT scan have been used in all the cases preoperalively and postoperatively. Preoperative CT was compared with postoperative CT. Main Outcome Measures Clinical symptoms and complications. Results All patients were followed up for 3 to 18 months. The postoperative scar of infracillary skin was not obvious. The composite hydroxyapatite was not rejected and dislocated in all cases postoperatively. No postoperative epiphora was found in either case. Preoperative diplopia and enophthalmos were corrected. Conclusion The treatment of medial orbital wall combined with orbital floor fracture via an isolated lower lid subciliary approach was feasible. But the incision was only used in the treatment of inferior medial orbital wall combined with orbital floor fracture, especially the transition area fracture between the orbital floor and medial orbital wall.

Rupture of Thoracic Empyema for Femur Neck Fracture Surgery under Combined Spinal-Epidural Anesthesia: A case report / 대한마취과학회지

Thoracic empyema can result from the pleural accumulation of infected fluid or the infection of accumulated pleural fluid. The causes of empyema are pneumonia, surgery of lung, mediastinum, diaphragm, trauma, and so on. The impact of anesthetic technique (regional versus general versus combination of both) on the respiratory complication rate has not been established. A 86-yr-old male patient, who had COPD about 15 years and chronic empyema for several months, scheduled to operation for a femur neck fracture. We report a case that this patient with COPD and empyema operated under combined spinal-epidural anesthesia and converted to general anesthesia because of the rupture of the chronic empyema.
