  • Analysis of Rehabilitation Needs, Measures Taken, and Their Effectiveness for the Wounded Following the Wenchuan Earthquake△

    Objective To investigate the recovery status of people wounded in the Wenchuan earthquake. Method Data were retrospectively collected from administrative documents in the Bureau of Medical Affairs, Sichuan Provincial Health Department. The severity of injury was assessed by Injury Severity Score (ISS). The data were recorded by EXCEL software and descriptive analysis was conducted. Results Our analysis results of rehabilitation treatment through Feb. 5, 2009 shows that 27,080 of the 28,008 patients had been treated and discharged, for a discharge rate of 97.8%. There were 928 patients still in hospitals at that time, including 55 cases of traumatic brain injury, 163 cases of paraplegia, 260 amputees, and 449 cases of severe spine, pelvis and other fractures. Some amputees needed to receive replacement of artificial limbs or stump dressing operation and rehabilitation; most patients who were installed internal fixation needed to removal and post-rehabilitation. Conclusions The effectiveness of rehabilitation is significant. Our work in the next stage should focus on (1) continuing to improve the establishment of province’s rehabilitation capabilities and increasing capital investment; (2) enhancing training for medical rehabilitation practitioners in order to improve operational standards and service capabilities; (3) developing the wounded rehabilitation standards in later stages, conducting follow-up and functional training in order to maximize recovery and return to society; (4) increasing employment opportunities for disabled persons.

  • CLASSIFICATION AND TREATMENT OF MONTEGGIA EQUIVALENT FRACTURES IN CHILDREN

    Objective To investigate the classification and treatment of Monteggia equivalent fractures in children. Methods A retrospective analysis was made on the clinical data of 35 cases of Monteggia equivalent fractures between January 2008 and January 2012. There were 17 boys and 18 girls with an average age of 7 years and 5 months (range, 1 year and 2 months to 14 years and 11 months). The causes of injury were tumbling injury in 25 cases, falling injury in 3 cases, and sport injury in 7 cases. The disease duration from injuries to admission ranged from 1 hour to 16 days (median, 28 hours). According to the criteria of self-made classification, there were 22 cases of type I (ulnar fracture with radial neck fracture or proximal radial epiphysis injury), 2 cases of type II (posterior elbow dislocation with radial neck fracture or proximal radial epiphysis injury), 10 cases of type III (ulnar fracture and/or olecranon fracture with humeral lateral condylar fracture), and 1 case of type IV (fractures of radius and ulna with radial neck fracture or proximal radial epiphysis injury). All patients were treated by open reduction and internal fixation/external fixation. Results All incisions healed by first intention without infection. Thirty-four cases were followed up 14 months on average (range, 12-18 months). All fractures healed at 2.5 months on average (range, 6 weeks to 5 months). According to Hospital for Special Surgery (HSS) score system, the results were excellent in 29 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 94%. No cubit varus/valgus or delayed ulnar nerve injury was observed. Conclusion New self-made classification is simple and easy to remember, and it is helpful to reduce omission diagnose rate and select therapeutic methods. Surgery is an effective method to treat Monteggia equivalent fractures.

    Objective To analyze the spinal injury in Wenchuan earthquake and to investigate its cl inical features. Methods Data of 146 patients in Wenchuan earthquake with spinal injuries (79 males, 67 females; aged 11-88 years old, average 51 years old) were collected and analyzed epidemiologically. Two patients under 16 years of age, 15 patients withthe fractures of spinous process, transverse process or vertebra lamina, 1 patient with spinal fractures of type A2 according to AO classification but no corresponding type in Denis classification, and 9 patients with upper cervical injuries were excluded. The remaining 119 patients were divided into two groups according to their age: group A in which 78 patients were under 60 years of age, including 40 males and 38 females aged 18-58 years old (average 41 years old), and group B in which 41 patients were 60 years of age or above, including 24 males and 17 females aged 60-88 years old (average 71 years old). Analyses for the two groups were compared. Results The leading causes of spinal injuries were fall from high places (27.40%) and crush by heavy objects (67.81%). According to Denis classification, the major types of spinal injuries were burst fracture (54.62%) and compression fracture (33.61%). Serious nerve injury, defined as grade A, B and C in ASIA neurological function assessment, occurred in 31.51% of patients. The most common injured site was in thoracic or lumbar vertebrae (78.77%), and 52.74% of patients had combined injuries, among which the fractures of l imb (30.14%) and rib (19.86%) were the most common. Multilevel spinal fractures happened to 22.60% of patients. Comparative analysis revealed the rate of injury caused by fall from high places in group A (34.62%) was much higher than that in group B (12.20%). The commonest type of fracture in group A was burst fracture (58.97%), and it was compression fracture in group B (48.78%). The rate of serious nerve injury in group B (24.39%) was much lower than that in group A (44.87%). The rate of combined injury and multilevel vertebral body injury in group B was 70.73% and 39.02%, respectively, which was much higher than that in group A (combined injury 43.59%; multilevel vertebral body injury 21.79%). There were significant differences between two groups in all the indicators derived from cl inical data (P lt; 0.05). Conclusion In Wenchuan earthquake, the leading causes of spinal injuries are fall from high places and crush by heavy objects, the major types of fracture are compression fracture and burst fracture, and the occurrence rates of spinal injury, combined injury and multilevel vertebral body injury are high.

  • CLASSIFICATION OF ATLAS PEDICLES AND METHODOLOGICAL STUDY OF PEDICLE SCREW FIXATION

    Objective To investigate the classification of atlas pedicles and the methods of the pedicle screw fixation. Methods To study the classification of atlas pedicles, 48 dry adult atlas specimens were measured. By atlas 3D-CT reconstruction, two transverse sections were establ ished by going through the one third of the lateral atlas pedicle and 2 mmbelow the vertebral artery sulcus. By setting 3.50 mm and 1.75 mm as the standardized diameter and radius for the screwand according to the thickness of bone substance of vertebral artery sulcus that went through the one third of the lateralatlas pedicle, the anatomical morphology of atlas pedicles were classified into three types: general type with 40 specimens (83%), l ight variation type with 6 specimens (13%), and severe variation type with 2 specimens (4%). The entry pathway was confirmed by the intersection l ine of the two transverse sections that went through the lateral one third of the atlas pedicle and 2 mm below the vertebral artery sulcus. The project-point of the entry pathway on the atlas posterior arch was considered to be the entry point. Forty-eight dry atlas specimens were used to measure the following relevant anatomic data with an electronic cal iper: the distance between the entry point and the posterior margin of the lateral mass (L1), the height of atlas pedicle at the entry point (L2), the vertical distance between the entry point and the inferior articular facet of the lateral mass (L3), the mass height at the entry point (L4), the mass width at the entry point (L5), the width of the atlas pedicle at the entry point (L6), the thickness of the pedicle under the vertebral artery sulcus at the entry pathway (H1). To research the method of the pedicle screw fixation, 12 fresh-frozen adult atlas specimens were adopted to simulate the fixation of the pedicle screw. The thickness of the bone substance of vertebral artery sulcus on both the left and the right sides of the pathway was grinded into 3 types: 1.5 mm and 2.5 mm, 1.5 mm and 4.0 mm, 2.5 mm and 4.0 mm, and each type had four specimens. The entry pathway was confirmed by the intersection l ine of two transverse sections that went through the lateral one third of atlas pedicle and 2 mm below the vertebral artery sulcus. Results On the left side, L1 was (5.79 ± 1.24) mm, L2 (4.55 ± 1.29) mm, L3 (5.12 ± 1.06) mm, L4 (12.43 ± 1.01) mm, L5 (12.66 ± 1.37) mm, L6 (7.86 ± 0.77) mm, and H1 (4.11 ± 1.25) mm. On the right side, L1 was (5.81 ± 1.26) mm, L2 (4.49 ± 1.22) mm, L3 (5.15 ± 1.05) mm, L4 (12.49 ± 0.98) mm, L5 (12.65 ± 1.38) mm, L6 (7.84 ± 0.78) mm, and H1 (4.13 ± 1.29) mm. There was no significant difference between the two sides (P gt; 0.05). After simulation of inserting screws, no screw in the specimens was found to break the bone substance in the sulcus of vertebral artery. Conclusion For the pedicle screw fixation of those patients whose atlas posterior arches are not high enough, we might partly drill through or beyond the atlas posterior arch. The entry point should be ascertained by preoperative 3D-CT reconstruction and intra-operative exploration.

  • FUNCTIONAL EVALUATION OF ELECTRICAL-INJURY NERVE USING SOMATOSENSORY EVOKED POTENTIAL TECHNIQUE

    OBJECTIVE: To investigate the characteristics and the pathologic classification of electrical-injury nerve using somatosensory evoked potential(SEP) technique. METHODS: SEP were detected and evaluated in 12 cases with electrical-injury nerve during operation, electrical stimulation was commenced from distal side of nerve where the structure of nerve looks normal under operating microscope, up to proximal side until evoking out a stable SEP predeterminate virtual value. Pathological examination and the following functional evaluation were compared with the values of SEP. RESULTS: At the site of nerve looking normal under operating microscope, perineurium appears normal or slightly thicken. But there are obvious fibrosis and fibrotic proliferation between fascicular and intrafascicular. Vessel plexus is not seen. At SEP stabilizely evoked site, nervous construction is normal, there are visible interfascicular vessel plexus and connective tissue appears loose. Comparing SEP values with pathological section, amplitude and latency of SEP is positively correlative with the quality of nerve. Eight cases repaired with SEP technique to select the anastomosis site for nerve transplantation were followed up, two-point discrimination reached grade III (America hand surgery association criterion) within 62.5% cases. CONCLUSION: SEP technique is valuable method for functional evaluation of electrical- injury nerve which has a complicated pathology. The pathology of electrical-injury nerve can be classified into 4 types, type A: fibrosis of nerve; type B: nerve looking normal under operation microscope, perineurium appears thicken, and there are obvious fibrosis and fibrotic proliferation between fascicular and intrafascicular, vessel plexus is rarely to see; type C: nerve looks normal, lymphocyte infiltration exists and it is obvious that there are many physalis-like, retrogressive construction in the section; type D: nervous construction is normal, there are visible interfascicular vessel plexus, and connective tissue appears loose, SEP always can be stably evoked.
