Clinical characteristics of Fourth Lumbar Spondylolytic Spondylolisthesis / 대한정형외과학회잡지

A most common site for the isthmic spondylolisthesis is at fifth lumbar vertebra(L5) and far less at fourth(L4). The pathogenic lesion in the pars interarticularis is essentially the same in LA and L5 isthmic spondylolisthesis, but the clinical characteristics may differ each other according to their anatomical and biomechanical differences. A retrospective review of 24 patients of LA(study group) and 27 patients of L5(control group) isthmic spondylolisthesis was undertaken for their medical records and radiographs to compare the clinical characteristics in each groups. Included in each groups were all patients who were surgically treated during the same period and followed for more than two years after surgery. In the study group, 18 of 24 patients were females having an average age of 42.5 years(ranging 34-65), while in the control group, 17 of 27 patients were males having an average age of 38,1 years (ranging 13-59). The symptoms were severe leg pain in most of the study group, but in the control group, the leg pain and back pain were equally complained. The degrees of slip were similar in two groups, but a narrowing of dise space at slip segment was more prominent in study group. The lateral radiographs taken in flexion and extension revealed more changes of slip in study group (4.7mm in study group vs 2.8mm in control group in averages), and more angular motion at slip segment in study group unless the dise space is not severely narrowed. A spinal stenosis in CT findings was disclosed in almost all patients of study group and in 18 patients of control group. The sizes of L5 transeverse process were bigger than twice as those of L4 in 17(70.8%) patients including 9(37.5%) sacralizations of L5 in suty group, while in control group they were only 8(29.6%) patients with no sacralization. The heights of intercreastal line revealed no difference in two groups. The surgical procedures in study group were fusion only in two and decompression with fusion in 22(91.7%) patients and those in control group were fusion only in 11 and decompression with fusion in 16(59.3%) paticnts. The satisfactory results of treatment were in 21(87.5%) patients of study group and 25(92.6%) patients of control group without significant difference between two groups. In conclusion, the L4 spondylolytic spondylolisthesis compared to L5 lesion was more unstable and developed spinal stenosis more often. The surgical treatment and decompression procedure were also more needed in L4 lesions particularly in agend women.

A Comparative Study of the Floating L4-5) vs Lumbosacral L4-S1) Spinal Fusions / 대한정형외과학회잡지

In cases of L4-5 spinal fusions, L5-S1 segment used to be included in the fusion traditionally for fear of progressive deterioration of the lumbosacral motion segment after fusion above. The purpose of this study was to evaluate the advisability of extension to L5-S1 segment in cases of L4-5 fusion for an isolated pathologic condition in L4-5 sement. A retrospective review of 72 patients with spinal fusion for an isolated pathologic condition in L4-5 segment was undertaken to compare the clinical results and adverse effects in two groups. One group consisted of 39 patients with floating L4-5 fusion(SF), and the other group consisted of 33 patients with L4-S1 fusion(LSF). The age, pathologic condition at L4-5, and the fusion method(lateral fusion) were matched in two groups. The mean follow-up period was 43.6 months(ranging 24-69 months). Comparisons were made for operative problems, post-operative complications, the amount of changes in angular motion at the adjacent segments to fusion at the last follow-up compared to the pre-operative motion, and the clinical results of treatment. The LSF group took 38 more minutes and lost 245 grams of more blood in averages to complete the additional surgical procedures compared with those in SF group. Several considerable post-operative complications were one deep infection in SF group and three metal failures of sacral fixation with subsequent two fusion failures in LSF group which were mostly concerned with the sacral fixations. The changes of angular motion at follow up compared to pre-operative motion in SF group were 1.5° gain in average (ranging 3° loss-6° gain) in L3-4 segment and 0.6° gain in average (ranging 5° loss-5° gain) in the L5-S1 segment. Those in L3-4 segment of LSF were 2.8° gain in average (ranging 2°-loss 9° gain). Therefore the higher stress and subsequent degeneration are more likely expected above the L4-S1 fusion rather than below the L4-5 fusion. The satisfactory clinical results were 89.7% in SF group and 87.9% in LSF group without significant difference between two groups. In conclusion there is no need to include the L5-S1 segment in the L4-5 fusion when the pathology is limited to L4-5 segment.

Open Reduction of Intra-Articular Fractures of the Calaneus through the Lateral Approach / 대한정형외과학회잡지

Displaced intra-articular fractures of the calcaneus result in serious and prolonged disability. These injuries continue to pose a therapeutic challange and there remains a great deal of controversy regarding treatment, operative versus nonperative. The lateral approach for open reduction, popularized by Palmer, has been used by many authors, with high percentage of excellent results. We treated 21 displaced intra-articular fractures of the calvaneus in 18 patients by open reduction and internal fixation through the lateral approach from July 1990 to May 1992 and the patients have been followed from 12 to 36 months from the time of their injury. The clinical and radiographic analyses were as follows; 1. The most common cause of injury was falls from a height: 19 fractures in 16 patients(88.8%), Spine fracture was most commonly associated injury : 5 patients (27.8%). 2. Fracture was classified according to classification of Paley and Hall. Eight fractures were tongue type(no comminution 4, with comminution 4), 12 joint depression type(no comminution 8, with comminution 4), and a comminuted type. 3. The average bohler tuber-joint angle was

The Causes of Neurogenic Symptoms in Spondylolytic Spondylolisthesis / 대한정형외과학회잡지

A retrospective study was undertaken to define the factors that cause the neurogenic symptoms in 18 cases of spondylolytic spondylolisthesis who were operated for leg pain and neurologic deficits of motor functions documented by neurologic examination or electromyographic findings in the Department of Orthopaedic Surgery, Fatima Hospital, Daegu for three years since June, 1986. The cases having other combined pathology to cause neurogenic symptoms were excluded. The causes were predetermined by preoperative x-rays, myelograms, electromyograms, and computerized tomograms and the causes were explored at surgery regarding the preoperative findings. The findings were compared with the avilable findings of 13 cases who were operated for low back pain only without any neurogenic pain in the leg during the same period. The cases were quite older and had narrower disc spaces than the back pain group but there were no significant differences in the degree of slipping and stability of slipped level between the two groups. The foraminal stenosis was found in all of the cases and a central stenosis was combined in a case. The intervertebral foramens were narrowed up-down in most of the cases between the bony prominence of proximal pars interarticularis above and the disc and vertebral body below but three cases had soft tissue mass only at the isthmic defect encroaching the foramen. There were hypertrophy of bone and/or soft tissue at the pars interarticularis in all cases. The nerve roots were mainly compressed up-down below pars interarticularis in the foramen in 8 cases and impinged at the anterior foramen in front of the pars interarticularis in 10 cases. The central stenosis was due to marked bony hypertrophy of pars interarticularis and osteophyte of vertebral body. The causes of neurogenic symptoms in spondylolytic spondylolisthesis were foraminal stenosis due to hypertrophy of bone and/or soft tissue at the pars interarticularis combined with narrowing of disc and seemed to be a process of degenerative changes occurring at the motion segment of slipped level.

Clinical Study on the fibular Strut Graft in the Ldiopathic Osteonercrosis of Femoral Head / 대한정형외과학회잡지

The idiopathic osteonecrosis of femoral head is one of the orthopaedic dilemma in regarding the treatment and various trials to preserve the femoral head were known to be effective in the early stage of the disease process. The conventional methods of core decompression and bone graft were not usually indicated in the progressed cases that disclose the subchondral fracture or collapse of the femoral head. Authors reviewed 15 cases of the free fibular strut grafts performed for the progressed idopathic osteonecrosis of femoral head since 1983 at the Department of Orthopaedic Surgery, Daegu Fatima Hospital with follow-up periods from 2 years and 2 months to 4 years and 6 months except for 2 cases who had secondary procedures because of progressive collapse of the femoral head after the bone grafting and the following results were obtained; 1. The cases were 14 males and a female aging from 28 years to 56 years and revealed crescent signs in 9 cases and early collapses in 6 cases on the pre-operative x-rays with involvement in the other sides in 10 cases. 2. The successful results in clinical and roentgenological evaluations were obtained in 8 cases(53%) and progressive collapse was prevented in 10 cases(67%). 3. The exact insertion of the graft up to the subchondral level through the necrotic bone was essential and no weight bearing for 1 year was neccessary for success. 4. The free fibular strut grafts were effective to prevent the progressive collapse in progressed idiopathic osteonecrosis of the femoral head.

Internal Fixation for the Lumbosacral Fusion Using Long Bone Plate and Screw / 대한정형외과학회잡지

The lumbosacral fusion has some problems because of it's biomechanical characteristics especially in the unstable spine of various causes and results considerable cases of pseudoarthrosis even with long immobilization. The conventional internal fixators for the spine are not adequate for the lumbosacral fixation with difficulty of sacral fixation maintaining lumbosacral lordosis and risk of the sacral nerves. Recently the pedicle screws and sacral screws connected to the plates or rods are known to be very effective and safe for the lumbosacral fixation permiting early mobilization and decreasing the incidence of pseudoarthrosis. Authors reviewed 10 cases of lumbosacral fusion with internal fixation using the long bone plates and screws which were managed since June 1986 at the department of orthopaedic surgery, Daegu Fatima Hospital and the followings were obtained. 1. The cases were 5 isthmic and 5 degenerative spondylolisthesis with enough spinal stenosis and instability before surgery or after decompression procedures having ages from 39 to 62 years old. 2. All cases had adequate decompression and bilateral intertransverse fusion combined with the internal fixation from 4th lumbar spine to sacrum. 3. Post-operative complications noted in 3 cases such as superficial infection, marginal skin necrosis, paralytic ileus, urinary difficulty and loosening of screws which were all improved without additional procedures. 4. There was no pseudoarthrosis at follow-up examination of 6 months to 1 year and 9 months in spite of a case of loosening of screws. 5. Ambulation was allowed in 2 weeks after surgery wearing lumbosacral corset and all satisfied the results having complete or significant improvement of the symptoms. 6. The internal fixation using long bone plates and screws for the lumbosacral fusion was considered to be effective with very low cost and good mobility.

The Late Complications of Prosthetic Replacement for the Femoral Neck Fractures / 대한정형외과학회잡지

The displaced femoral neck fractures remain a major challenge to orthopaedic surgeons as the elderly population is increasing. Successful union by internal fixation after adequate reduction without avascular necrosis is primary goal since the functional results having own femoral head are much superior to those having prosthetic femoral head, but prosthetic replacement is indicated for some patients with fresh fractures who need early ambulation as well as neglected fractures and failed internal fixations. The early result after prosthetic replacement was known to be very satisfactory but the late complications are becomming the major problem. Authors reviewed 21 cases of the prosthetic replacements for the femoral neck fractures which were followed for more than one year and managed at Fatima Hospital during the years between 1975-1984 and the following results were obtained. 1. The cases were 8 males and 13 females having ages from 42 to 87 years with average 69 years old. 2. The cases were 11 elderly fresh fractures, 6 neglected fractures, 2 failed osteosynthesis and 2 others. 3. Moore and Thompson prosthesis were used and 13 of them were fixed with bone cement. 4. The early result evaluated at 3 months after surgery revealed satisfactory in 90% but the final result at average 3 years and 5 months ranging from 1 year to 6 years and 2 months revealed satisfactory results in 58% 5. There was no significant early post-operative complications. 6. The late complications were 8 cases of acetabular erosions and these were combined with stem loosening in 2, subsidence in 2 and deep infection in 1 case. 7. The late complications started to reveal at about 3 years after surgery and occurred in younger and active patient. 8. The prosthetic replacement for femoral neck fracture is recommended for the inactive patient or the patient with expected activity less than 3 years.

Clinical Study of Posterior Comminution of the Femoral Neck Fractures / 대한정형외과학회잡지

The management of the femoral neck fractures remains a major challenge to the orthopaedic surgeons because there are many critical complications such as non-union and avasular necrosis in spite of the advanced technics of treatment. The posterior comminution of this fracture is known to be an important comtributing factor of these complications as the most important cause of the instalility of reduction after internal fixation as well as difficulty of stable reduction, Authors reviewed 61 cases of the femoral neck fractures which were able to identify the presence or absence of posterior comminution on x-ray or operative findings and were managed at Daegu Fatima Hospital during the 10 years from 1975 to 1984 and the following results were obtained. 1. The incidence of posterior comminution in 61 femoral neck fractures was 56% in x-rays of lateral view and operative findings. 2. Open reductions were performed in 31% of 39 cases in which reductions were necessary for internal fixation and 43% of the fractures with posterior comminution were unstable to reduce by closed method while 88% of the fractures without postrior comminution were reduced by closed method. 3. The positions of reductio were in valgus in 46% and anatomic in the rest of cases and valgus reductions were more common in the cases of posterior comminution. 4. Loss of the reduction after internal fixation noted in 48% of the fractures with posterior comminution and 9% without posterior comminution. 5. 77% of the fractures united including 14% of mal-union and the late complication of non-union noted in 14% and avascular necroris in 9% in 35 cases which were followed for over 1 year. 6. The normal unions were more common in the fractures without posterior comminution, the cases of open reduction and the reduction in valgus position. 7. Most of the mal-unions and non-unions noted in the fractures with posterior comminution, the cases of closed reduction and the reduction in anatomic position. 8. These results suggest that the posterior comminution of the femoral neck fracture causes considerable instability and the better results could be expected in the femoral neck fractures with posterior comminution by the reduction in valgus and by the open reduction if necessary.

Primary Subacute Pyogenic Osteomyelitis of Long Bones / 대한정형외과학회잡지

Primary subacute pyogenic osteomyelitis is defined as a bone infection of insidious onset lasting for more than several weeks without any acute systemic toxic reactions and is known to have the problem of diagnosis because there is no inflammatory symptoms or signs and X-ray findings are similar to various bone tumors. Authors reviewed 29 cases of primary subacute pyogenic osteomyelitis of long bones admitted at Fatima hospital during the years between 1976 and 1984. The osteomyelitis of infants and the osteomyelitis modified by antibiotics were excluded. The diagnosis of the cases was confirmed by bacteriological examination and/or tissue examination. The results were as follows. 1. The cases were 18 males and 11 females and 19 adults and 10 children. Male predominence was noted in children. 2. The involved bones were 11 tibias, 10 femurs and all other long bones. The involved sites were 18 metaphysis and 11 shafts. 3. All of the cases has insidious onset of local pain without any acute systemic symptoms and most of the cases has local tenderness but local deep swelling noted in about half of the cases. 4. There were many cases with elevated ESR and a few cases of slight leukocytosis. 5. The confirmed infecting organism was all staphylococcus in 16 cases of the cultures from the 25 lesions. 6. The X-ray findings were Brodies abscess in 10, illdefined cavity in 3, diffuse bones absorption in 5, diaphyseal lesion of adult with localized cortical sclerosis in 5 and with localized medullary abscess in 3 and diaphyseal lesion of children with localized medullary abscess and periosteal reaction in 3 cases. 7. All of the cases cured rapidly with rare recurrence after treatment by simple local excision in 4 and curettage in 22 cases combined with antibiotic therapy and local immobilization.

Surgical Treatment of the Spondylolisthesis with Sciatica / 대한정형외과학회잡지

Low back pain and radiating pain in the leg are the main symptoms of the spondylolisthesis and various surgical treatments are recommended after having enough conservative treatments. The spinal fusion in situ either posterior, posterolateral or anterior route is the usual method for symtomatic spondylolisthesis or to prevent progression of slipping but the neurogenic symptoms in the legs are not well solved, so the decompression procedures are necessary. The authors reviewed 26 cases of isthmic spondylolisthesis having low back pain and sciatica which are operated during the 10 years since 1973 at Fatima Hospital and the followings are obtained. 1. There were 15 males and 11 females with ages from 18 years to 63 years having average 40.1 years. 2. The displaced vertebrae were 5th lumbar in 18 and 4th lumbar in 8 cases and the degree of displacement was Grade I in 14, Grade II in 10, Grade III in 1 and no slipping in 1 case. 3. The types of surgery were decompression and H-graft in 22, simple posterior fusion in 3 and Gll's procedure in 1 case. 4. The laminas were considerably loose in all cases and there were small fibrous mass at the pars area in half of the cases. .5. The spine became very stable immediately after H-grafting and the intervertebral foramen became widened freeing nerve root. 6. Bony union obtained in 88% and satisfactory result in 85% at the follow-up from 6 months to 7 years and 2 months with average 1 year and 7 months. 7. The decompression is necessary for the radiating pain in the leg and H-grafting is satisfactory and simple procedure after decompression laminectomy.

Sacral Agenesis: Report of Two Cases in A Family / 대한정형외과학회잡지

Four families having identical sacral agenesis were reported in the literatures and an another family is added here. This family has an eleven year old boy and a seven year old girl who have identical complete sacral agenesis without spincter disturbance but with some anomalies in the other spines, rib and progressive club feet. These cases are followed for six years and the foot deformity was corrected by surgery.

A Clinical Study on Chronic Osteomyelitis of Adult Long Bones / 대한정형외과학회잡지

The chronic osteomyeltis of the adult long bones has different problems from the acute osteomyelitis and osteomyelitis of the children. The ischemic scar tissues and infected bones of the chronic csteomyelitis in the adult are resistant to the antibiotic therapy and their healing mechanisms are delayed. The chronic osteomyelitis has no single effective method of treatment since every case reveals different conditions and the treatment should be individualized case by case. 87 cases of chronic osteomyelitis of the adult long bones were studied in the department of orthcpaedic surgery, Fatima Hospital for 7 years during the years between 1973 to 1979. The cases were 65 male and 22 female having ages 35 years in average and the duration of the osteomyelitis was 14 years and 4 months in average ranging from 3 months to 50 years. The cau ative organisms were mostly staphylococcus but Gram (−) bacilli were found in 28% and the adjacent joint problems were found in 38% The cases were analysed in 5 different groups according to x-ray findings as follows; I. Group with sequestrum: 23 cases having sequestra with varying degree of bone sclerosis and destruction. Most cases had draining sinus but the soft tissue involvement was not severe. II. Sclerotic group: 32 cases having significant bone sclerosis with minimal destructicn if any. The soft tissue involvement and scarring were severe but involvement of the bone marrow was not significant. The duration of osteomyelitis was longest having recurrent episodes of the painful swelling in most cases. III. Destructive group: 17 cases with significant bone destruction with varying degree cf sclerosis. The involvement of the bone marrow was significant and soft tissue involvement was not marked The duration of osteomyelitis was short mostly. IV. Group with skin problem: 9 cases having scar problems overlying tibia. V. Group with complication: There were 2 pathologic fractures of the femurs, 3 quamous cell carcinomas on the lower legs and a severe deformity of a leg. Treatment was mostly surgical including 4 amputations. The surgical method was focused on saucerization of the bone and extensive excision of the infected soft tissues and the scar tissues. 23 cases having small or no dead cavity after mobilization and suture of the adjacent healthy soft tissue closed primarily. Otherwise the cavity was packed open for econdary healing in other 23 cases including several cases having big cavity which was unable to close the skin. The cases having big cavity were prepared for continueus irrigation in 14 caes which were able to closed skin. The transposition of muscles to fill the dead cavity was performed in 4 cases that had big cavity and was unable to close skin. The results were healing in 10 weeks in 54% and after 10 weeks in 38% and 8% failed to heal with the first trials. The recurrence of the ostecmyelitis was found in 9 cases among the 42 cases followed for I year and 3 months in average mostly in group II and in cases of primary closure and open packing.
