Observational Analysis of Korean Society of Spine Surgery Annual Congress: (2001-05) Free Paper: From Presentation to Publication

STUDY DESIGN: A review of all presentations at the Korean Society of Spine Surgery(KSSS) congress from 2001 to 2005. OBJECTIVES: To determine the presentation to publication rate in peer-reviewed journals of abstracts presented at the KSSS congress and evaluate the consistency between the presented abstract and published full-text counterpart. SUMMARY OF LITERATURE REVIEW: The rate of publication for presentation at international meetings has been determined but there has been no study for the KSSS. MATERIAL AND METHODS: This study reviewed all podium presentations of the past KSSS Spring and Fall meetings from 2001 to 2005. A computer search for each abstract was performed. The final published journal, time to publication and publication rate were evaluated according to subspecialty. The published full-text article was compared with the original abstract and evaluated for consistency with respect to the author, material and method, and result. RESULTS: A total of 288 free-papers were identified, of which 167 of them were published as full-text articles. The mean time to publication was 12.15 months. The publication rates according to the subspecialty were basic 67%, lumbar 68%, cervical 64%, deformity 50%, trauma 53%, minimal 14% and others 51%, respectively. CONCLUSION: The presentation to publication rate of the Korean society of spine surgery podium presentations was lower than other international meetings but the articles showed a high consistency rate.

Treatment of Candida Infection after TKA

PURPOSE: We wanted to review the clinical results of staged reimplantation in patients who had candidal infection after total knee arthroplasty. MATERIALS AND METHODS: We reviewed five patients who had a candidal prosthetic knee infection, as was assessed by synovial fluid culture. Amphotericin B was intravenously administrated to all five patients during the postoperative period for six weeks and followed for at least twelve months. We carried out two-stage re-implantations with using antifungal agent-impregnated bone cement. Whether or not infection recurred was evaluated according to the symptoms and radiologic and hematologic studies. The clinical results were analyzed on the basis of the range of motion and hospital for special surgery (HSS) score. RESULTS: The final review showed that all of the symptoms disappeared. We could not find any loosening on the radiologic studies and all five patients had normal C-reactive protein values on serological exams. The mean postoperative range of motion was 1degrees (range: 0~5)~99degrees (range: 70~130) and the mean HSS score improved from 49.4 (range: 44~64) points to 73 (range: 65~90) after the re-implantation. CONCLUSION: We successfully controlled five candidal prosthetic knee infections by removing the components in conjunction with using an antifungal- impregnated bone cement and staged re-implantation after a 6 week course of intravenous antifungal drugs.

The Changes of Postural Balance in Patients with Total Hip Arthroplasty

PURPOSE: To investigate the changes in postural balance before and after total hip arthroplasty (THA) using computerized dynamic posturography MATERIALS AND METHODS: This was a prospective study of 18 patients undergoing total hip arthroplasty. We evaluated each patient's postural balance prior to, and at least 12 months after, total hip arthroplasty by using computerized dynamic posturography. We compared the preoperative equilibrium scores with the postoperative equilibrium scores. Clinical results were assessed for all patients preoperatively and postoperatively using the Harris hip scoring system. We investigated whether postural balance improves, and what factors were related to this parameter. RESULTS: Patients showed significant improvement in postural balance by means of proprioception after total hip arthroplasty (p<0.05). We found, during intercepting visual compensation, that an increase in the Harris hip score was correlated with an improvement in balance (p<0.01, r = 0.649). CONCLUSION: Patients with Total hip arthroplasty showed improvement in dynamic postural balance through proprioceptive recovery, and balance improved as the Harris hip score increased. This resulted in decreased pain, recovery of articular function, enhancement of physical activity, and ultimately improvement in postural balance by means of total hip arthroplasty.

Intramedullary Plate Fixation for the Comminuted Fracture of the Femoral Shaft: A Case Report

A case of the comminuted fracture of the femoral shaft with osteoporosis is presented. The patient lacked sufficient bony stability and cortical bone-contact which allows union by conventional reconstruction method. Therefore, the authors performed a technique utilizing an intramedullary plate in combination with the standard lateral plate in order to obtain bony stabilization, early range of motion of the knee, and partial weight bearing ambulation and the technique is introduced.

The Factors associated with Postural Control after Anterior Cruciate Ligament Reconstruction

PURPOSE: We analyzed the correlation of the Lysholm score, anterior displacement of tibia on stress radiography and muscle strength around the knee with postural control after anterior cruciate ligament reconstruction and also compared them with the normal subjects. MATERIALS AND METHODS: Twenty-five patients after ACL reconstruction were evaluated with Lysholm knee score, anterior displacement on stress radiography with Telos, muscle strength around the knee with Biodex dynamometer and postural control with posturography. RESULTS: The postural control had significant correlation with the Lysholm knee score & anterior displacement on stress radiography(r=0.565, r=0.783, p0.05). Patients group with 5mm instability under anterior displacement on stress radiography showed no significance compared with normal control group, while the group with instability more than 6mm showed significant differences in some conditions com- pared with control group. CONCLUSION: Postural control after ACL reconstruction have significant correlation with Lysholm score and we presumed that the acquisition of mechanical stability of the knee after ACL reconstruction may be one of the important factors associated with the recovery of postural control by improvement of the proprioception.

Balance in Patients After TKA

PURPOSE: To investigate the improvement in balance after TKA and the difference of balance between posterior cruciate ligament retaining & posterior cruciate ligament substituting prostheses. MATERIALS AND METHODS: Twenty-six patients scheduled to undergo TKA were randomly assigned to receive either PCL-retaining or PCL-substituting prosthesis. The balance of the subjects were checked prior to and at least six months after the operation by computerized dynamic posturography. We investigated whether the balance improve and the difference of change between the implants. RESULTS: Patients showed significantly the improvement of balance by the knee proprioception after TKA (p0.05). CONCLUSION: The balance by the proprioception improves as the HSS Knee Score increases after TKA, and does not show the difference between the implants.

The Effect of Peripheral Neurolysis in Diabetic Feet / 대한족부족관절학회지

PURPOSE: We evaluated the effect of nerve decompression for restoration of plantar sweating and sensation in diabetic neuropathic feet, and we selected diabetic neuropathic patients with the possibility of overlying entrapmental neuropathy. MATERIALS AND METHODS: From June 2002 to May 2003, we have investigated and follow-up examed 10 patients with diabetic neuropathic feet, with decreased sensation in their lower limb, who underwent peripheral nerve decompression. The surgical procedure was multiple neurolysis of the common peroneal nerve, posterior tibial nerve and its three branches of one limb. We compared the operated limb with the opposite, unoperated limb. We performed history taking, physical examination, sweat secretion test, touch sensory test using Semmes-Weinstein monofilaments and electrodiagnostic study, pre-operatively and post-operatively. RESULTS: On 6 months after the operation, the post-operative tests showed that there were noticeable improvements to sensation, statistically (P<0.05), but there was no change in the sweat secretion test. According to the Cseuz criteria, 7 patients out of the 10 patients who received the multiple neurolysis showed excellent or good results. CONCLUSION: We observed that the peripheral nerve neurolysis could be benefit for improving sensation and alleviating pain of the diabetic neuropathic feet with nerve entrapmental symptoms, but there was no change in the sweat secretion on short-term follow-up. To identify whether the effect will be continued or not, additional follow-up will be required.

Candida Infection After Total Knee Arthroplasty: A Case Report

Candida infections after total knee replacement are extremely rare and show no specific symptoms and signs, thus make it difficult to diagnose. It is desirable to perform fungi culture from the beginning in case of persistent swelling and burning sensation in patients after total knee replacement with risk factors such as intraarticular steroid injection, intravenous drug abuse, immunosuppressive therapy, malignant hematologic tumor, etc. Positive culture of candida should never be considered as contaminated study, and be treated immediately. We report a case of candida infection after total knee arthroplasty, which was treated with staged reimplantation.

Reversibility of DNA Ploidy Changes Observed in Pulmonary metastasis in the Murine Osteosarcoma after Orthotopic Implantation / 대한정형외과학회잡지

The difference in DNA ploidy pattern between primary and metastatic tumor remains an interesting question. We examined whether the observed change of tumor ploidy is permanent or whether it is reversible after reinoculation of the metastatic foci to an orthotopic site of another mouse. We isolated 14 metastatic pulmonary nodules from 8 mice with MGH-OGS murine osteosarcoma of thigh, and inoculated these nodules into the thighs of twenty nine C3H/Sed mice. In addition, we performed the cytoflowmetric examination of the primary tumor, the inoculated metastatic pulmonary nodules, and the regrown tumor after orthotopic inoculation. In the primary thigh tumor of FS MGH-OGS mice, the ploidy pattern was primarily aneuploid(Average values were % Diploid Cells: 23% and the mean DNA Index: 1.39). Examination of the pulmonary nodule revealed a significant increase in the diploid cell population(Mean: 54%) in 79% of nodules and a significant decrease in the mean DNA Index(Mean: 1.24) in 50% of the nodules. The tumors regrown after orthotopic implantation of metastatic pulmonary nodules however showed the same ploidy pattern and regrown parameters as was seen in the primary tumor, regardless of the ploidy pattern of the implanted metastatic nodules. This data support the concept that the lesion that goes to the lung may have hyperpercentage of surviving diploid cells(rather than aneuploid), but once reimplanted into the "native" site became primarily aneuploid again.

Cervical Myelography in Brachial Plexus Injuries / 대한정형외과학회잡지

With the increase of frequency and the recent development of surgical treatment in brachial plexus injury, the requirement for accurate assessment between supra and infraganglionic injury is increased. Cervical myelography has been the popular tool in evaluating the root lesion since the first introduction of Murphey et al. in 1947. However, the invasiveness of procedure has been the impediment to the common-use. But with the utilization of water-soluble contrast media, Metrizamide, such impediment can be alleviated. Author has performed myelography in 27 patients along with surgical exploration in 18 patients since 1984. And the results were as follows. 1. 85% of 27 patient revealed anomaly of root in myelography. 2. Traumatic menimgoceles were typical findings and most of them were located at C7 and C5. 3. Myelography reaveled 70%(28 root) of anomalies among 40 root lesions, confirmed by surgical explorations. 4. Myelography is considered to be very effective in evaluating supra and infraganglionic root lesions when its results is correlated with physical and other neurological examination.

A Clinical Study of Popliteal Artery Injury / 대한정형외과학회잡지

With the increase of motor accident, the rate of popliteal artery injury is increased, As the injuries are critical, early diagnosis and prompt treatment can save the limb. 27 cases of popliteal artery injury patients were reviewed and the result was as follows ; l. Amputation rate was 11%, as 3 out of 27 cases failed. There was no correlation between ischemic time and the rate of amputation. 2. Complete resection of all injured portion of vessel and reconstruction of patency through interposed saphenous vein graft was often indicated to avoid tension at the anastomosis site. 3. The rate of fasciotomy was positively correlated with the ischemic time. 4. Medial approach is preferred to posterior approach, since it makes proximal extension of exploration possible, and decrease the incidence of joint contracture. 5. Complications noted are wound infection, systemic sepsis and venous stasis, but they could be treated with proper management. However, nerve deficit due to associated nerve injuries was resist to treatment.

Microsurgical Reconstruction of Extremities by Cutaneous or Myocutaneous Free Flaps / 대한정형외과학회잡지

The authors performed microsurgical reconstruction by free cutaneous or myocutaneous flaps transfer in 104 cases, who were sustained of extensive soft tissue injuries on their extremities by accident. These 104 cases were operated in 6 years from 1980 to 1986 and were consisted of 47 cases of latissimus dorsimyocutaneous free flaps, 36 cases of scapular free flaps, 18 cases of dorsalis pedis sensible free flaps, and 3 cases of groin flaps. Most of them were males(80 cases) and were in third decade(28 cases). The youngest case was 2-year-old baby and the oldest one was 76-year-old woman. The traffic accident was the most frequent cause of injuries(55 cases), and the others were burn, industrial injuries, and cultivator accidents. Most of the microsurgical reconstruction were performed in lower extremity injuries(81 cases), especially below the ankle joints(65 cases). The average dimension(width and length) of free flaps were 7.3×14.3cm in latissimus dorsi free flaps, 5.6×8.2cm in scapular free flaps, and 4.5×5.9cm in dorsalis pedis free flaps. The dorsalis pedis free flaps were successful in 100%, the scapular free flaps were in 83.3%, the latissimus dorsi myocutaneous free flaps were in 89.4%, and the groin free flaps were in 33.3%, And the overall viability of 104 free flaps was 87.5%.

Partial Capital Resection in Legg-Calve-Perthes' Diseases / 대한정형외과학회잡지

Partial capital resection (cheilectomy, partial capitectomy, excision of a lip) has gained an accepted place in treating the Legg-Calve-Perthes disease with severely malformed femoral head in which containment surgery has rarely been successful. The clinical experiences in six children aged over 10 years who complained marked limitation of hip motion with severe collapse and subluxation of femoral head are presented. Postoperative results including clinical and radiological findings are quite promising.
