Analysis of clinical effects of iliolumbar fixation in treating sacrum fracture of Denis type II / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the clinical effects of iliolumbar fixation for the sacrum fractures of Denis type II.</p><p><b>METHODS</b>The clinical data of 86 patients with sacrum fracture of Denis type II treated by iliolumbar fixation from January 2008 to January 2012 were retrospectively analyzed. There were 55 males and 31 females, aged from 17 to 55 years old with an average of 39.1 years. Among them, 73 cases complicated with pelvis fracture and 13 cases with acetabular fracture; 37 cases with sacral neurological symptoms and 49 cases without sacral neurological symptoms. Fracture healing time, nerve function, clinical function and complications were observed in the patients.</p><p><b>RESULTS</b>In 86 cases, 6 cases were out of followed-up and 80 cases were followed up from 24 to 71 months with an average of 36 months. The mean fracture healing time was 13 weeks (ranged, 10 to 38 weeks). According to Gibbons scoring to evaluate the neurological function, preoperative nerve rehabilitation, lower limbs feeling, lower limbs activity,bladder and rectum function,total score respectively were 0.62 +/- 0.04, 1.54 +/- 0.35, 1.12 +/- 0.18, 0.23 +/- 0.01, 3.46 +/- 0.47 and postoperative respectively were 0.82 +/- 0.12, 0.36 +/- 0.04, 0.05 +/- 0.01, 0.03 +/- 0.01, 1.25 +/- 0.22, there were statistically significant differences between preoperative and postoperative (P < 0.05). According to Majeed scoring to evaluate the clinical function, postoperative pain, standing, sitting, sexual life, work ability, total score respectively were 22.54 +/- 4.02, 27.93 +/- 5.46, 8.47 +/- 3.61, 2.54 +/- 1.33, 16.46 +/- 4.34, 81.32 +/- 8.73, 60 cases got excellent results, 17 good, 3 fair. The main complications including fracture nonunion of 5 cases,deep incision infection of 1 case, and screw prominence resulting uncomfortable of 8 cases.</p><p><b>CONCLUSION</b>Iliolumbar fixation has the advantages of stable fixation, satisfactory functional rehabilitation, less complications, and is a good method in treating sacrum fracture of Denis type II.</p>

Discussion on Clinical and Diagnosis Program of Integrative Medicine / 中国中西医结合杂志

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

Treating Neer two- and three-part of proximal humeral fractures through anterolateral acromial approach and deltopectoral approach / 中国骨伤

<p><b>OBJECTIVE</b>To compare clinical results of treating Neer two- and three-part of proximal humeral fractures between anterolateral acromial approach and deltopectoral approach.</p><p><b>METHODS</b>From January 2009 to December 2012, 49 patients with Neer two- and three-part of proximal humeral fractures were treated with locked plate fixation. In anterolateral acromial approach group, there were 22 patients including 9 males and 13 females with an average of (63.2±7.6) years old, while 27 patients in deltopectoral approach including 12 males and 15 females with an average of (62.9±7.0) years old. Operative time, blood loss during operation, fracture healing time and complications were observed and compared, postoperative Constant-Murley scoring and VAS scoring were applied for evaluate function of shoulder joint and pain at 3 months, 1 and 2 years respectively.</p><p><b>RESULTS</b>All patients were followed up from 24 to 41 months with an average of 34.5 months. Operative time, blood loss, fracture healing time in anterolateral acromial approach group was (68.20±7.04) min, (151.30±20.57) ml, (10.88±4.90) weeks respectively, and better than that of in deltopectoral approach group which was (75.81±13.70) min, (242.10±37.25) ml and (13.60±2.45) weeks. Three months after operation, Constant-Murley scoring and VAS score in anterolateral acromial approach group was 88.32±5.45, 0.41±0.63 and better that of in deltopectoral approach group which was 63.53±8.31, 1.65±1.02. There was no significant differences between two groups in Constant-Murley scoring and VAS score at 1 and 2 years after operation. Each group has one case occurred loss of length humerus head height, and there was 1 case with subacromial impingement, 1 case with bolt loose and 2 cases with delayed union in deltopectoral approach. No axillary nerve injury, humeral head necrosis and breakage of internal fixation occurred both of two groups.</p><p><b>CONCLUSION</b>Both of anterolateral acromial approach and deltopectoral approach are effective in treating Neer two- and three-part of proximal humeral fractures, and can obtain excellent outcomes. Moreover, anterolateral acromial approach has advantage of less trauma, less blood loss, shorter operative time, rapid recovery of shoulder joint function and fracture.</p>

Vertebral column resection via posterior approach for kyphotic deformity in children: A retrospective study of 10 cases / 解放军医学杂志

Objective To summarize the experience, technique and curative effect of vertebral column resection via posterior approach for kyphotic deformity in children. Methods The clinical data of 10 children (3 males and 7 females; aged 6-15 years with average of 11 years) who suffered from kyphotic deformity and undergone one-stage posterior vertebral column resection and reconstruction from Jul. 2010 to Aug. 2011 were retrospectively analyzed. The pre-operative Cobb angle of kyphosis was 76°-112° with an mean of 97.8°. Nervous system symptoms were found in 2 children, of them one was of Frankel C class and another one was of Frankel D. All the children underwent one-stage posterior vertebral column resection, pedicle fixation combined with bone graft. Results The operation was successfully in all the patients. The average surgery time was 373min (240-560min), the intraoperative blood loss was 1115ml (550-2200ml), the average post-operative Cobb angle of kyphosis was 29.3°(10°-43°), and the correction rate was 70.0%. The torso and shoulder imbalance in all the 10 children was significantly improved, and dorsolumbar pain was markedly relieved. The Frankel classification of 2 children having preoperative nervous system symptoms were both ameliorated to class E after operation. Conclusions Posterior vertebral column resection with pedicle screw-rod fixation is an effective and safe surgical method for the treatment of kyphotic deformity in children. Satisfactory stability of short segment fixation and bone graft fusion can be accomplished.

Changes in serum electrolyte levels after seawater immersion of open abdominal wound and drowning in dogs / 南方医科大学学报

<p><b>OBJECTIVE</b>To assess the effects of seawater immersion of open abdominal wound and drowning on plasma electrolyte levels in dogs.</p><p><b>METHODS</b>Twenty-one dogs with open abdominal wounds were randomly divided into 3 groups, namely the control group (n=7), seawater immersion group (n=7) and seawater immersion and drowning group (n=7). The dogs in the control group were subjected to simple open abdominal wound, and those in the latter two groups were immersed into seawater after the abdominal injury. The changes in the plasma electrolytes and osmotic pressure were observed after the treatments. RESULTS AMD CONCLUSION: Seawater immersion of the open abdominal wound results in hypematremia, hyperkalemia and hypertonic dehydration, and the effect is proportional to the length of immersion time, but seawater airway perfusion does not cause obvious changes of the plasma electrolytes and osmotic pressure in dogs.</p>
