RESUMEN

Traumatic absence of the entire radial shaft in children has not been reported though there are a few reports of adult cases. We report a 5-year-old boy with traumatic absence of the entire right radial shaft. The Define's reconstruction procedure was chosen to localize the surgery only to the distal forearm and avoid further additional damage to the forearm muscles. The child's forearm was successfully reconstructed by the authors' modified Define's procedure, which was followed until his maturity. Hand function was well maintained.

RESUMEN

Even in an era of remarkable medical advances, there is an issue of why tuberculosis remains in the list of disastrous diseases, afflicting humans and causing suffering. There has not been a plausible answer to this, and it has been suggested that clinicians and medical scientists could presently not win the war against the tubercle bacilli. With regards to this issue, based on the authors' own clinical and research experiences, in this review, the available literature was revisited in order to address the raised questions and to provide recent information on characteristics of tubercle bacilli and possible ways to more effectively treat tuberculosis.

RESUMEN

STUDY DESIGN: A prospective radiographic study of cervical spine with congenital monosegment fusion. PURPOSE: To evaluate the effect of cervical synostosis on adjacent segments and the vertebral morphology. OVERVIEW OF LITERATURE: There are numerous clinical studies of adjacent segment disease (ASD) after monosegment surgical fusion. However, there was no report on ASD in the cervical spine with congenital monosegment synostosis. METHODS: Radiograms of 52 patients, aged 5 to 90 years, with congenital monosegment synostosis (CMS) between C2 and C6, who complained of neck/shoulder discomfort or pain were studied. 51 were normally aligned and one was kyphotically aligned. RESULTS: Spondylosis was not found in the patients below 35 years of age. Only 12 out of 24 patients with normally aligned C2-3 synostosis had spondylosis in 19 more caudal segments, and only one at C3-4. A patient with kyphotic C2-3 had spondylolysis at C3-4. In 8 patients with C3-4 synostosis, spondylosis was found in only 9 caudal segments (4 at C4-5, 4 at C5-6, and 1 at C6-7). The caudate C4-5 disc was the most liable to degenerate in comparison with other caudate segments. Caudal corporal flaring and inwaisting of the synostotic vertebra were the features that were the most evident. In 2 of 9 C4-5 and 7 out of 10 C5-6 synostosis patients, spondylosis was found at the two adjacent cephalad and caudate segments, respectively. Only corporal inwaisting without flaring was found. In all cases, spondylosis was confined to the adjacent segments. More advanced spondylosis was found in the immediate caudal segment than the cephalad one. CONCLUSIONS: It is concluded that spondylosis at the mobile segments in a synostotic spine is thought to be a fusion-related pathology rather than solely age-related disc degeneration. Those data suggested that CMS definitely precipitated the disc degeneration in the adjacent segments.

RESUMEN

STUDY DESIGN: Medical record-based survey. PURPOSE: To survey the overall incidence of the intra- and postoperative complications and sequelae, and to propose the preventive measures to reduce complications in the spinal tuberculosis surgery. OVERVIEW OF LITERATURE: There is no study focused on the surgery-related complications and sequelae, with some touching lightly on the clinical problems. METHODS: There were 901 patients in this study, including 92 paraplegics. One hundred eighty-six patients had no visible deformity, while those of 715 patients were visible. Six hundred fifty-nine patients had slight to moderate non-rigid kyphosis, and 56 had severe rigid kyphosis. Sixty-seven out of 92 paraplegics had slight to moderate non-rigid kyphosis, and 25 had severe kyphosis. There were 134 cervical and cervicodorsal lesions, 518 thoracic and thoracolumbar lesions, and 249 lumbar and lumbosacral lesions. Seven hundred sixty-four patients had primarily anterior surgeries, and 137 had posterior surgeries. Instrumentation surgery was combined in 174 patients. RESULTS: There were intra- and postoperative complications: direct large vessel and neurological injuries (cord, roots, nerves), late thrombophlebitis, various thoracic cavity problems, esophagus and ureter injuries, peritoneum perforation, ileus, wound infections, stabilization failure, increase of deformity and late adjacent joint and bone problems. Thrombophlebitis and sympatheticolysis symptoms and signs in the lower limbs were the most common complications related with anterior lumbar and lumbosacral surgeries. Kyphosis increased in 31.5% of the non-instrumented anterior surgery cases (42% in children and 21% in adults). CONCLUSIONS: The safe, effective and most familiar surgical procedure should be adopted to minimize complications and sequelae. Cosmetic spinal surgery should be withheld if functional improvement could not be expected.

RESUMEN

BACKGROUND: To assess the preoperative nutritional status of patients with various disorders and to provide data for pre- and postoperative patient management plans, particularly in the elderly. There is no published information on age-matched and disease-matched preoperative nutritional/immunologic status for orthopedic patients, especially in the elderly, in Jeju. METHODS: In total, 331 patients with four categories of orthopedic conditions were assessed: 92 elective surgery patients, 59 arthroplasty patients, 145 patients with fractures, and 35 infection patients. Malnutrition was defined as body mass index (BMI) below 18 kg/m(2) of expected body weight (below 20% of normal), serum albumin/globulin ratio below 1.5 (normal range, 1.5 to 2.3), albumin level below 3.5 g/dL, total lymphocyte count below 1,500 cells/mm(3), and lymphocyte/monocyte ratio below 5 versus 1. RESULTS: In 92 elective surgery patients, the average BMI was 23 kg/m(2), hemoglobin was 15 g/dL, lymphocytes (2,486 cells)/monocytes (465 cells) ratio was 6.1, and the albumin (4.4 g/dL)/globulin (2.5 g/dL) ratio as a protein quotient was 1.7. Among the 59 hip and knee arthroplasty patients, the average BMI was 25 kg/m(2), hemoglobin was 12 g/dL, lymphocytes (2,038 cells)/monocytes (391 cells) ratio was 6.6, and albumin (4.1 g/dL)/globulin (2.4 g/dL) ratio was 1.6. No subject showed malnutrition. Among the 145 fracture patients, the average BMI was 23 kg/m(2). The hemoglobin level was 13 g/dL, monocytes (495 cells)/lymphocytes (1,905 cells) ratio was 1 versus 4.6, and albumin (4.1 d/gL)/globulin (2.5 d/gL) ratio was 1.6. However, both ratios decreased after 70 years of age. Among the 17 of 35 infection patients, albumin levels were below 3.5 g/dL, the average BMI was 22 kg/m(2), lymphocytes (1,532 cells)/monocytes (545 cells) ratio was 2.4 versus 1, and albumin (3.0 g/dL)/globulin (3.3 g/dL) ratio was 0.9, while in 18 patients albumin levels were over 3.5 g/dL, the average BMI was 22 kg/m(2), hemoglobin was 12 g/dL, lymphocytes (1,998 cells)/monocytes (583 cells) ratio was 3 versus 1, and albumin/globulin ratio was 1.4. Thus, in the infection group, approximately 50% of the patients showed poor nutrition and immunosuppression. CONCLUSIONS: It was found that nutritional and immune condition deteriorated gradually to some degree in elderly patients over 60 years of age.

RESUMEN

PURPOSE. To report on 23 patients with giant cell tumour (GCT) of the femur or tibia treated with curettage, electrocautery, burring, phenol irrigation, and cementation. METHODS. Records of these 14 men and 9 women aged 22 to 38 (mean, 31) years were reviewed. The most common site involved was the distal femur (n=13), followed by proximal tibia (n=8), proximal femur (n=1), and distal tibia (n=1). The lesions were classified as grade I (n=3), grade II (n=18), and grade III (n=2). Based on histology, the tumour stage was classified as grade I (n=5) and grade II (n=18). Two of these patients had recurrences, which were initially treated with simple curettage and bone grafting of the distal femur and distal tibia. RESULTS. The mean follow-up period was 5.7 (range, 2.5-10.1) years. 14 of the 23 patients were followed up for over 10 years. No patient developed any local recurrence, remote metastasis, or complication related to surgery or adjuvant therapy. CONCLUSION. Combined treatment entailing curettage, electrocautery, burring, phenol irrigation, and cementation was effective in treating GCT of bone.

RESUMEN

We retrospectively reviewed 15 children (four with paralysis) and 39 adults (10 with paralysis) with tuberculosis of the cervical spine to assess the drug responses, disease arrest, and healing times. Ten children and 13 adults were treated nonoperatively, while anterior débridement was performed in five children (two with paralysis) and anterior radical surgery in 26 adults (10 with paralysis). Triple chemotherapy (isoniazid, rifampin, ethambutol [or pyrazinamide for children]) was given to all patients for 12 months. The tuberculosis began to arrest after 3 months of chemotherapy and healed within 12 months. Spontaneous fusion occurred in all adults but only two of the 10 children. Surgical fusion was achieved within 12 to 16 weeks in adults. In nonoperated patients, an initial kyphosis of 12 degrees progressed to 17 degrees at final followup in the children and an initial kyphosis of 9 degrees progressed to 13 degrees in 13 adults. In operated patients, the initial kyphosis of 13 degrees in adults became 2 degrees at the time of the fusion, while the initial kyphosis of 14 degrees in the five children progressed to 18 degrees. Patients with paraplegia recovered completely within 14 days on average (range, 1-42 days) after treatment. Recovery was gradual in the nonoperative group, while it occurred within 3 days in the operative group.

RESUMEN

STUDY DESIGN: Pott's paraplegic patients with severe spinal deformity were reviewed retrospectively after being treated with chemotherapy and/or decompressive surgery. OBJECTIVES: To determine the most appropriate treatment protocol and to predict the prognosis for Pott's paraplegics with severe spinal deformity. SETTING: Catholic University of Korea Medical Center and Moon-Kim's Institute of Orthopedic Research, Seoul, Korea from 1971 to 1996. METHOD: In this study, there were 33 patients (eight children and 25 adults), ranging from 13 to 56 years of age. They developed spinal tuberculosis at the age of 9 years (range, 2-29 years), and remained neurologically symptom free from an average of 16 years (range, 4-27 years). Four adults who responded well to treatment initially suffered relapses of paraplegia. Only six patients had previously received a full course of triple chemotherapy. Seven (two children, five adults) had healed disease, and 26 (six children, 20 adults) had active disease. Eleven cases had frequent drainage from the sinuses. Kyphoscoliosis was found in 11 patients: four children and seven adults. The remaining patients had kyphosis only. Among the 26 patients with active tuberculosis, 10 had triple chemotherapy itself and the rest had additional decompression surgery (10 anterior and six posterior). All seven patients with healed tuberculosis were subjected only to surgery (two anterior and five posterior). RESULTS: In seven patients with healed tuberculosis, surgery did not improve neurologically except in one child patient. In four patients, the severity of paralysis remained unchanged and two patients, deteriorated neurologically after surgery. In six children with active tuberculosis, there were remarkable neurological recoveries by either conservative treatment or surgical decompression. Seven adults with active tuberculosis recovered slowly, improving by one or two Frankel grades (three Frankel C, three D, one E). In 11 out of 13 surgically treated adults with active disease, paralysis that had persisted for less than 3 months gradually improved by one or two Frankel grades. One Frankel A and one Frankel B paraplegic patients who had paralysis that had lasted through 6 months did not recover after surgery. CONCLUSION: The neurological recovery of Pott's paraplegics with severe spinal deformity resulted in three different outcomes: (1) severe deformity is different from moderate and mild deformities; (2) patients with healed tuberculosis had poorer prognosis than patients with active tuberculosis; (3) children had better prognosis than adults. Furthermore, patients with paralysis persisting over 6 months did not recover neurologically after surgery.

RESUMEN

Fifty-six adults (average age, 38 years) with active tuberculosis of the lumbar and lumbosacral spine were treated conservatively with triple chemotherapy for 12 to 18 months. The minimum followup was 3 years. Three methods of assessments of the chronologic changes of sagittal spinal deformity were used on lateral radiographs of the lumbar spine obtained with the patient standing: deformity, kyphos angles, and total lumbar lordosis. The lumbosacral joint angle was measured for tuberculosis of the lumbosacral joint. The disease healed in all patients with a minimum increase of kyphosis, although in 23 patients there was minimal new involvement of the adjacent vertebral bodies within 6 months of treatment. The pattern of the involved vertebral body collapse in tuberculosis of the lumbar and lumbosacral joints was vertical (telescoping), along a longitudinal axis that minimized the progression of kyphosis. The outcome was judged on the basis of residual kyphosis (British Medical Research Council criteria) and found to be favorable in 96.4% (54 patients). Triple chemotherapy for lumbar and lumbosacral tuberculosis is effective in curing the disease and in minimizing the residual kyphosis through early diagnosis and immediate initiation of chemotherapy. The pattern of vertebral body collapse is the telescoping type, which is the determining factor in minimizing residual spinal deformity.

RESUMEN

Spontaneous fractures of the hip which developed after strenuous walking exercise in 8 elderly people are reported. All patients had Singh hip index 4 or below at the time of initial examination and walked from 8,000 to 10,000 steps per day. This presentation aims to arouse the attention of physicians, recreational sports coaches, and elderly people to the deleterious effects of strenuous walking exercise on bone, and it looks for an optimal level of walking exercise according to the elderly patient"s bone quality. Walking exercise should be stopped immediately if pain in the hip develops and continues without relief for several days or more. The optimal walking frequency per day should be prescribed on the basis of the Singh index or T-score of BMD. If the BMD is 1/3 to 1/2 of normal, walking frequency should be adjusted to 1/3 to 1/2 of those of the normal adult with good bone quality.
