Evaluation of systems of grading of neurological deficit in tuberculosis of spine

STUDY DESIGN: Prospective comparative study. OBJECTIVE: To compare the efficacy of the ASIA scoring system and Tuli's classification for assessment of neurological status in a typical case of Pott's paraplegia/tetraplegia and suggest a suitable classification. SETTING: Department of Orthopaedics of University College of Medical Sciences and GTB Hospital, Delhi, India. METHODS: A total of 33 cases of tuberculosis of the spine with paraplegia were evaluated serially for the severity of the neurological deficit by grading systems as suggested by Tuli and ASIA score, during the course of treatment. A total of 111 readings of neurological status were recorded and analysed. RESULTS: Tuli's grading was found to be sensitive for detection of early stage (grade I) of neurological deficit. The rest of the grades (grade II, III, IV) of Tuli's classification have a wide range of sensory-motor deficit and hence are insensitive to early detection of any deterioration/improvement in the neurological status. The ASIA score failed to grade all types of neurological deficit associated with the Pott's spine. The sensory-motor score obtained by the ASIA scale depends on the level of involvement of the spinal cord. The higher the level of the cord damage, the poorer is the score. CONCLUSION: Neither Tuli's grading nor the ASIA scale alone can effectively grade all stages of neurological deficit in tuberculosis of the spine. The neurological deficit in tuberculosis of the spine should be described in stages and each stage should have sensory and motor scoring. A new staging system of Pott's tetraplegia/paraplegia is suggested.     

人工关节松动病因的研究

目的：探讨人工关节松动的病因。方法：选择７例松动人工髋关节，翻修手术时取松动关节周围的界膜组织；同时选择１０例骨折内固定患者，拆除内固定物时取内固定物周围瘢痕组织。标本做组织学检查和肿瘤坏死因子（ＴＮＦ）测定。选择１０只成年兔，将２０只模拟假体分别置入双侧股骨远端。分别于术后第６、８、１０、１２、１４周向右侧膝关节腔注射聚乙烯微粒悬液，作为实验侧；左侧膝关节腔注射生理盐水，作为对照侧。第１６周取股骨远端标本，做组织学检查。结果：松动人工髋关节周围的界膜组织主要含大量的组织细胞和聚乙烯微粒，而骨折内固定物周围的瘢痕组织主要为纤维成分，无聚乙烯微粒。松动关节周围界膜组织中的ＴＮＦ浓度明显高于骨折内固定物周围的瘢痕组织（Ｐ＜０．０１）。动物实验发现，实验侧模拟假体周围有一层充满组织细胞的纤维结缔组织界膜，并有明显骨吸收和骨溶解现象，而对照侧无明显纤维结缔组织界膜，也无骨破坏现象。结论：人工关节磨损后，产生大量的磨损微粒，微粒刺激组织细胞分泌ＴＮＦ等溶骨性因子，这些溶骨性因子直接或间接地激活破骨细胞，从而引起假体周围骨吸收、骨溶解，最终导致假体松动。假体松动后又可加重磨损，产生更多的微粒，形成恶性循环

Frequency of complications of manipulation of the spine

Summary A survey of all members of the Swiss Medical Association of Manual Medicine was undertaken for the year 1989. Informative data were given by 425 respondents on the frequency of complications of manipulation as related to the spine. The number of thoraco-lumbar manipulations during 1989 (225 working days) was 805 for each respondent, and the number manipulations of the cervical spine 354. Thus, the total number of thoraco-lumbar manipulations was 342 125, and the total number of cervical manipulations was 150 450. The overall incidence of side-effects of transient complications due to cervical spine manipulation such as disturbance of consciousness or radicular signs was 1: 16716. Seventeen patients (ratio 1: 20 125) after manipulation of the lumbar spine presented, in addition to increased pain, a transient sensorimotor deficit with precise radicular distribution. Nine of the 17 patients (ratio 1: 38013) developed a progressive radicular syndrome with sensorimotor defict and radiologically verified disc herniation and had to be referred for surgery. Side effects and complications of cervical and lumbar spine manipulation are rare. Taking in to account the yearly number of manipulations performed by a single physician in Switzerland and the rate of complications, it can be calculated that a physician practicing manual medicine will encoutner one complication due to manipulation of the cervical spine in 47 years and one complication due to lumbar spine manipulation in 38 years of practice. However, it is important that a careful clinical assessment is carried out to avoid complications due to manipulation carried out on the basis of inappropriate indications. Furthermore, the decision as to which technique is indicated for any particular functional disorder of the spine should be made on the basis of rational criteria resting on a knowledge of clinical biomechanics, functional anatomy and neurophysiology. The authors recommend a prospective morbidity study to be carried out among physicians, chiropractors, osteopaths and physiotherapists, taking into account the different indications and therapeutic techniques in relation to complications.

Sonographic evaluation of hypertrophy of septum of Bertin

Sonography was utilized to evaluate 12 patients with hypertrophy of the septum of Bertin. To confirm the diagnosis, angiography was used in 7 patients and radionuclide imaging in 2. Three sonographic characteristics were found: (1) an isoechogenic, ellipsoid mass with an echogenic linear rim of renal sinus fat; (2) contiguity of the mass with a normal-placed septum of Bertin; and (3) the occurrence of the mass effect always at the level of the emergence of the renal vein. The sonographic findings could be divided into two definite types. Type I showed moderate hypertrophy with a mass effect ranging from 1.1 by 2.3 cm to 2.0 by 3.2 cm in diameter, usually presenting with a smooth contour and discrete mass effect on the intravenous pyelogram (IVP). Type II showed severe hypertrophy with a mass effect ranging from 3.2 by 4.0 cm to 3.5 by 4.5 cm in diameter, usually presenting with a lobulated contour and irregular stretching of the calyceal system on IVP. The differential diagnosis is discussed. In conclusion, we found that sonography associated with excretory urography is an accurate method for the diagnosis of hypertrophy of the septum of Bertin.     

Evaluation of outcome of treatment of congenital clubfoot

The study was undertaken to determine whether existing systems of outcome evaluation of clubfoot are comparable; to determine the relationship between the shape of the foot, its function, and radiological tarsal relationships; and to identify which objective variables used in the assessment of clubfeet are reproducible.Fifty treated idiopathic clubfeet were assessed by the scoring systems of Laaveg and Ponseti, McKay, Magone, and Ghanem and Seringe. Although there was a good correlation between the scores, there was very poor agreement between the grading of feet by these different systems.The feet were also evaluated using a new scoring system that has 3 domains of evaluation, viz, morphological, functional, and radiological. Comparison of the scores in each of these domains showed that there was a correlation between morphology, function, and radiological measurements of tarsal alignment. Several of the criteria used in this new scoring system were reproducible.     

Substantiation of the selection of a method of surgical treatment of varicose veins of the legs

An examination and operative treatment of 207 patients have shown that findings of plethysmometry and plethysmography reflecting the state of the direct and retrograde blood flow in the veins of lower extremities help to the correct selection of the method of surgery without phlebography. Long-term results of the operation confirm this conclusion.     

Choice of the method of treatment of unilateral fractures of the femur and bones of the shin

The authors present their experience in the treatment of 74 patients with unilateral fractures of the femur and the bones of the crus. The peculiarities of these injuries which unfavourably affect the results of the treatment are discussed. Four versions of treatment are distinguished, with surgical treatment of fractures of the femur and the bones of the crus being the preferable one. The best results, concerning both the duration of the period of in-patient treatment and the final outcome, were obtained in cases of combined intraosseous osteosynthesis of the femur and perosseous osteosynthesis of the fragments of the tibia with Ilizarov's apparatus.     

Comparative evaluation of the methods of treatment of dislocations of the clavicle

An analysis of treatment was made in 93 patients divided into three groups: conservative treatment (11 patients), operations by traditional methods (28 patients), surgery using constructions of titanium nickelide (54 operations). It was found that the conservative treatment of complete acromioclavicular end dislocation was followed by a repeated displacement, development of deforming arthrosis and deformity of the area of injury. Transcapticular fixation of acromioclavicular end dislocation resulted in the development of deforming arthrosis (68%), the incidence of this complication depending on the kind of operation. The greatest inclination of the construction to migration was noted after fixation with wires. After the application of a titanium nickelide construction the most frequent process was resorption of the bone around the construction in the shape of a hook (36%) which resulted in some patients in subluxation (11%) and development of deforming arthrosis (4.5%).     

Management of sequelae of septic arthritis of hip

A nine years old boy, who had suffered septic arthritis at the age of two years and presented now with a limp, hip instability, leg length discrepancy. The patient was treated by adductor tenotomy and upper tibial pin traction. When head remnant reached the level of the acetabulum, open reduction and Pemberton osteotomy was done to achieve cover of the femoral head. The purpose of this report is to highlight the six years followup of reconstruction of sequale of septic arthritis of hip joint.     

Criteria of assessment of restriction of vital activity of patients after total endoprosthesis of the hip joint

Total endoprosthesis of the hip joint is an effective method of rehabilitation of patients with a severe pathology of the hip joint. But the lack of exact criteria of assessment of restriction of vital activity of patients after total endoprosthesis results in leveling the effects of medical rehabilitation due to the existing stereotype solution of the MSE bureau and so the majority of patients (90%) after operation get invalidization of the I and II groups for a long time without sufficient causes. Results of complex clinico-rentgenological, biomechanical, electrophysiological examinations and expert assessment of 450 patients after implantation of various domestic and foreign endoprostheses allowed the elaboration of differentiated criteria for the examination of restricted viral activity depending on the nosological form of the disease, degree of the disturbance of the statico-dynamic function, prognosis, complications, character and conditions of work.     

Results of the treatment of fracture of the odontoid process of the axis

At the Rehabilitation Institute in Konstancin there were 80 patients treated due to the fracture of the dens epistrophei within the years 1970-1986. In all the cases the fracture was within the base of the dens. More than 50% of the patients were over 50 years of age at the time of injury. On admission about 34% of patients had neurological disturbances of various degree manifested by paresis of the extremities. The leading cause of spine injury were falls from a height (60%), particularly from a horse-cart. In 55% of cases the injury was through extension mechanism. Surgical treatment was applied in 35 cases (29 cases of posterior fusion of CI-C1I by bone grafting and wire loop, 6 cases of axis dens and vertebral body CI1 fixation by AO screw, by B?hler method). The remaining 45 cases were conservatively treated. The paper presents the radiological results of conservative and surgical treatment as well as an analysis of the neurological recovery.     

Analysis of a series of cases of liver metastasis of colorectal carcinoma

The Authors present a six years case-report concerning 135 patients operated on colo-rectal carcinoma (82 of them are still followed up). The incidence of hepatic metastases (synchronous and metachronous) has been 30.37% in all. The preoperative ultrasonography has shown an 11% about margin mistake to visualize secondary lesions of liver. They have acknowledged the intraoperative ultrasonography very useful to visualize occult metastases and to guide an exeresis operation. The resectability of hepatic metastases from colo-rectal cancer has been of 12.19%. Synchronous forms have been rarely operable (5.88%) because they are constituted by multiple and disseminated lesions. They have found an higher incidence of operable forms among the metachronous metastases (42.85%), whose average time of appearance from the primary operation has been about 13 months. The operative mortality and the complications following hepatectomy have been null. The average survival time from operation has been over 22 months. Therefore they recognized the importance of a careful follow-up to find precociously operable lesions.     

Blunt injury of duodenum with avulsion of papilla of Vater--report of a case

In a 52-year-old man, there was a complete separation of the duodenum with avulsion of the papilla of Vater from the head of the pancreas due to blunt abdominal trauma. He was successfully treated by an anastomosis of the ampulla to the jejunum of a Roux-en Y limb, after removal of the entire duodenum and partial gastrectomy, followed by gastrojejunostomy of the Billroth II-type, instead of pancreaticoduodenectomy. The patient is well at 15 months after this surgery.     

Pathogenesis of carcinoma of the papilla of Vater

Most adenomas and carcinomas of the small intestine and extrahepatic bile ducts arise in the region of the papilla of Vater. In familial adenomatous polyposis (FAP) it is the main location for carcinomas after proctocolectomy. In many cases symptoms due to stenosis lead to diagnosis at an early tumor stage. In about 80%, curative intended resection is possible. Operability is the most relevant prognostic factor. Most ampullary carcinomas resp. carcinomas of the papilla of Vater develop from adenomatous or flat dysplastic precursor lesions. They can be sited in the ampulloduodenal part of the papilla of Vater, which is lined by intestinal mucosa. They also can develop in deeper parts of the ampulla, which are lined by pancreaticobiliary duct mucosa. Intestinal-type adenocarcinoma and pancreaticobiliary-type adenocarcinoma represent the main histological types of ampullary carcinoma. Furthermore, there exist unusual types and undifferentiated carcinomas. Many carcinomas of intestinal type express the immunohistochemical marker profile of intestinal mucosa (keratin 7–, keratin 20+, MUC2+). Carcinomas of pancreaticobiliary type usually show the immunohistochemical profile of pancreaticobiliary duct mucosa (keratin 7+, keratin 20–, MUC2–). Even poorly differentiated carcinomas, as well as unusual histological types, may conserve the marker profile of the mucosa they developed from. These findings underline the concept of histogenetically different carcinomas of the papilla of Vater which develop either from intestinal- or from pancreaticobiliary-type mucosa of the papilla of Vater. Molecular alterations in ampullary carcinomas are similar to those of colorectal as well as pancreatic carcinomas, although they appear at different frequencies. In future studies, molecular alterations in ampullary carcinomas should be correlated closely with the different histologic tumor types. Consequently, the histologic classification should reflect the histogenesis of ampullary tumors from the two different types of papillary mucosa.     

Results of operative treatment of fractures of the posterior wall of the acetabulum

BACKGROUND: The purpose of this study was to determine the clinical outcome in patients in whom a displaced fracture of the posterior wall of the acetabulum had been treated by open reduction and internal fixation. METHODS: One hundred patients who had had open reduction and internal fixation of an unstable unilateral fracture of the posterior wall of the acetabulum were studied. Ninety-four patients were assessed at a mean of five years (range, two to fourteen years) after the injury. Six patients with a poor result were followed for less than two years. The functional outcome was evaluated with use of the clinical grading system adopted by Letournel and Judet with incorporation of modifications by Matta. Patient, fracture, and radiographic variables were analyzed to identify possible associations with functional outcome. RESULTS: The reduction of the fracture, as determined with plain radiography, was graded as anatomic in ninety-seven patients and as imperfect in three. The clinical outcome at the time of final follow-up was graded as excellent in fifty-five patients, very good in twenty-five, good in nine, fair in one, and poor in ten. The radiographic result was excellent in eighty-one patients, good in five, fair in four, and poor in ten. There was a strong association between the clinical outcome and the final radiographic grade. Variables identified as risk factors for an unsatisfactory clinical result included a delay of greater than twelve hours before reduction of an associated hip dislocation, an age of fifty-five years or older at the time of injury, intra-articular comminution, and osteonecrosis. CONCLUSIONS: The uncomplicated radiographic appearance and relatively simple operative approach for fractures of the posterior acetabular wall belie the risk of poor results. Prompt reduction of an associated hip dislocation is imperative. Fractures in elderly patients and those with extensive comminution are more likely to have a poor clinical result. However, a high likelihood of a long-term good-to-excellent result can be expected following anatomic reduction and internal fixation of these fractures.
