Chinese Journal of Orthopaedics 2000;0(11):-
Objective To investigate whether the bone harvested from Cloward discectomy with trephine could substitute for iliac-crest bone grafts in arthrodesis procedure. Methods We reviewed the 30 patients with cervical spondylotic myelopathy involving a single level, which had been managed with anterior trephination discectomy and arthrodesis by the bone chips harvested from within the trephine. The bone chips harvested with trephine were then trimed and implanted erectedly similar to Robinson arthrodesis procedure. All cases had been followed-up for an average of 4.75 years. The latest results were analyzed according to JOA score system and recovery rate. The fusion outcome were assessed by anteroposterior and flexion and extension lateral radiographs of the cervical spine. Results At the latest followed-up examination, clinical results were excellent in fifteen patients(50% ), good in eleven(36.7% ), fair in three(10% ) and poor in one (3.3% ). X-ray showed solid fusion in all, and no dislodgment of the grafts. However, the cervical curves had a little loss. There was no significant bone grafts subsidence. Conclusion In cervical anterior decompression the bone chips obtained in trephination could substitute for other type of bone grafts for arthrodesis. The postoperative outcomes were not affected by the loss of the cervical curves.

Objective To evaluate the surgical techniques of open reduction and internal fixation and its clinical results of trimalleolar fractures retrospectively. Methods Between March 1996 and October 2002, 48 consecutive patients, including 27 males and 21 females with an average age of 42.8 years, were treated for trimalleolar fractures. According to the system of Lauge-Hansen, the fractures were classified as pronation-external rotation(grade Ⅳ) injury in 20 cases, and supination-external rotation(grade Ⅳ) in 28 cases. The time from injury to operation was from 2 hours to 21 days. The operation was delayed due to associated injury, skin conditions and so on, and then the patients were manipulated primarily and immobilized with a posterior plaster splint. The medial, lateral and posterior malleolus were exposed by anteromedial and Gatellier-Chastang approaches. The reduction and internal fixation started with the posterior, then the medial and the lateral malleolus and distal tibiofibular syndesmosis in sequence. The ankles were immobilized with plaster in neutral position and elevated. All patients were assessed with Baird and Jackson ankle scoring system based on pain, instability, walking ability, movement and radiological manifestations. Results The follow-up period varied from 6 to 36 months with an average of 13 months. The rates of clinical result were excellent in 26, good in 15, fair in 5 and poor in 2 respectively. The total rate of good to excellent results was 85.4%. There were no local complication, malunion and nonunion of the fractures and the deformity of the ankle. However, the inserted screw to distal tibiofibular syndesmosis was broken in one case. Conclusion Trimalleolar fractures require open reduction and internal fixation more often, especially while the fragment of posterior malleous is so large that it should be anatomically reduced and immobilized with internal fixation. It can ensure anatomical joint restoration and union for the ankle trimalleolar fractures, only by achieving most satisfied kinematics of the ankle joint.

Objective To investigate the effects of glucagon like peptide 2(GLP 2) on the mRNA expressions of GLP 2 receptor (GLP 2R) and proglucagon gene(PG) in postburn rats. Methods A total of 55 Wistar rats were randomly divided into three groups including burn group, GLP 2 treatment group(treated with GLP 2, 200 ?g/kg, b.i.d ) and normal control group. Rats were sacrificed at 6, 12 h and 1, 3 and 5 d after burn injury. The proliferating cell nuclear antigen(PCNA) expression and the histological changes of the intestinal mucosa were determined by immunohistochemical staining. mRNA expressions of GLP 2R and PG were detected by RT PCR at 6, 12 h and 1, 3 and 5 d after burn injury. Results The expression of PCNA in rat intestinal mucosa decreased at 1 d after burn injury, but it was stronger in GLP 2 treatment group than that in burn group. Histological observation revealed that intestinal villi in GLP 2 treatment group were regularly arranged without obvious epithelial shedding. PG mRNA expression peaked at 12 h, 1 and 3 d after burn injury. No change of PG mRNA expression was found after treatment with GLP 2. Decreased GLP 2R mRNA expression was found in postburn rats, but after treatment with GLP 2, increased GLP 2R mRNA expression was found. Conclusion GLP 2 supplementation can keep the structure of the postburn rat intestinal mucosa without affecting PG gene expression. The mechanism may probably be related to the promotion of the mRNA expression of GLP 2R of the intestinal mucosa in rats.

BACKGROUND: The environmental change of regeneration of peripheral nerve fiber can accelerate the regeneration of nerve fiber and the recovery of nerve function. Physiotherapy can improve the local microcirculation of the injured area, and promote and stimulate the recovery course of trauma. Therefore, whether choosing different physiotherapies and controlling irradiation dose can speed up the regeneration of nerve fiber?OBJECTIVE: To observe the effects of different physiotherapies in promoting the regeneration of injured nerve fiber.DESIGN:Randomized grouping and controlled animal experiment.SETTING: Laboratory of Anthropotomy and Histo-Embryology Department,Peking University Health Science Center.MATERIALS: The experiment was conducted in the Laboratory of Anthropotomy and Histo-Embryology Department, Peking University Health Science Center, from September 2001 to September 2002. Fifteen adult male SD rats, weighting 185-220 g, were selected.INTERVENTIONS: The model of sciatic nerve injury was established and randomly assigned to 3 groups. Bio-spectrum group and infrared group with 5rats in each received the corresponding physical irradiation. Injury control group was given no irradiation. The slices of sciatic nerve at the operation side of the animals in the three groups were collected on day 14 after operation. The degeneration rate of the injured nerve fiber was observed under the optical microscope to make indirect assessment of the protective effect of physiotherapy after the nerve was injured.MAIN OUTCOME MEASURES: The degeneration rate of nerve fibers at the breakpoint and at 4 points near the spinal cord ( 1,2,3,4 mm) and away from the spinal cord( 1,2,3,4 mm).difference in the degeneration rate of nerve fibers at the breakpoint away from the spinal cord in bio-spectrum group and infrared group as compared with the degeneration rate of nerve fibers in bio-spectrum group(68% ) and infrared group(89% ) was obviously reduced and that in control group was the the spinal cord in the 3 groups showed decreasing trend: the closer to the spinal cord, the fewer the degenerative nerve fibers. The number of degenerative nerve fibers was the smallest in bio-spectrum group, second smallest in infrared group, and the largest in control group.CONCLUSION: The assisting physiotherapy can decrease the number of regenerative nerve fibers, thus promoting and accelerating their recovery. Irradiation with bio-spectrum equipment is more effective.
