RESUMEN

This study compared the clinical and radiological findings of nonanatomic transtibial (TT) technique with intraspongious fixation and anatomical anteromedial portal (AMP) technique with extracortical button implant in anterior cruciate ligament (ACL) reconstruction. A total of 54 patients with isolated ACL rupture were included in this prospective study. The patients who had the intraspongious fixation by nonanatomical TT technique were allocated to Group 1 (n = 27). The patients with extracortical fixation by anatomical AMP technique were placed in Group 2 (n = 27). The clinical scores of the patients were evaluated with the International Knee Documentation Committee Evaluation Form, Tegner activity score, and Lysholm II Functional Scoring. The tibial and femoral tunnels were evaluated with three-dimensional computed tomography. The kinematic examinations were performed with a Biodex System 3 Pro isokinetic dynamometer. There was no significant difference between the groups in terms of demographic data (p > 0.05). The postoperative clinical scores improved significantly in both the groups compared with the preoperative levels (p = 0.001), but there was no significant difference in the postoperative clinical scores between the groups (p > 0.05). In the extension and flexion of 60 to 180 degrees/s, the peak torque and the peak torque/body weight values of the repaired knee to intact knee ratios showed significant differences in favor of Group 2 (p = 0.001). In both the groups, no significant difference was found between the mean extent of the tunnel enlargement (p > 0.05). The mean tunnel height was significantly greater in Group 1 (45% ± 9.86 vs. 34.11% ± 10.0%) (p = 0.001). When the localization of the tunnel enlargements (proximal-middle-distal) was examined, a significant difference was found between the groups (p = 0.001). Although the AMP technique, which is a more anatomic reconstruction, had an advantage with regard to tunnel enlargement and the isokinetic muscle studies, there was no difference between the two techniques in terms of the clinical results.

RESUMEN

STUDY DESIGN: This was a retrospective analysis. OBJECTIVE: The objective of this study was to evaluate the predictive value of the 4 different scoring systems Tomita, Bauer modified, Tokuhashi revised, and Van der Linden and some parameters that are used in these scoring systems. SUMMARY AND BACKGROUND DATA: Prediction of the survival period before treatment for spinal metastasis is extremely important. A lot of scoring systems have been described to predict the survival periods and to select the ideal treatment modality in the literature. MATERIALS AND METHODS: Retrospectively 146 patients with spinal metastasis were investigated between 2002 and 2011. The following parameters were analyzed: age, pathologic vertebra fracture, neurological deficit, visceral metastasis, diagnosis of primary tumor and its spinal metastasis interval, other skeletal metastasis, involved region of vertebra, and undergone spinal surgery. Patients were also scored by the 4 different scoring systems. The survival period was calculated from date of diagnosis of the spinal metastasis to the date of death or last follow-up (minimum: 12 mo). Cox regression, Kaplan-Meier survival test, and Cronbach α tests were performed for statistical analysis. RESULTS: Median overall survival for all patients was 13 months (range: 1-68 mo). The primary tumor (P=0.015), existence of visceral metastasis (P=0.017), presence of pathologic vertebra fracture (P=0.009), and undergone spinal surgery (P=0.047) showed significant influence on survival. Each scoring system was reliable and concordant with the other scoring systems (Cronbach α=80%); however, after 2 years, Modified Bauer score appeared to be the most reliable system for predicting survival (Cronbach α=25%). CONCLUSIONS: According to this analysis, lung cancer, visceral metastasis, pathologic vertebra fracture, and undergone spinal surgery have shown a negative effect on survival. All 4 scoring systems were reliable for predicting survival of patients with spinal metastatic disease. However, modified Bauer scoring system seems to be more predictive after 2 years. LEVEL OF EVIDENCE: Level III.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the effects of PLIF and TLIF on sagittal spinopelvic balance and to compare radiological results of two surgical procedures with regard to spinopelvic parameters. METHODS: Thirty-five patients (34 female and 1 male; mean age: 52.29 ± 13.08 (range: 35-75)) with degenerative spondylolisthesis cases were included in the study. Patients were divided into two groups according to surgical technique: PLIF and TLIF. The level and the severity of listhesis according to Meyerding classification were assessed and spinopelvic parameters including sacral slope, pelvic tilt, pelvic incidence (PI), lumbar lordosis, and segmental lumbar lordosis were measured on digital X-rays. All preoperative and postoperative parameters and the results were compared between two groups. RESULTS: The age distribution was similar in both groups (p = 0.825) and there was no difference between the mean PI of the groups (p = 0.616). In 15 patients, spondylolisthesis level were at the L5-S1 level (PLIF: 8, TLIF: 7), in 16 patients at the L4-L5 level (PLIF: 6, TLIF: 10) and in 4 patients at the L3-L4 level (PLIF: 2, TLIF: 2). According to Meyerding classification, before the operation, the sliding grades were 0 in 4 patients, 1 in 21 patients, 2 in 7 patients, and 3 in 3 patients. The grades changed into 0 in 28 patients, 1 in 5 patients, and 2 in 2 patients after surgery. There were no differences in the grade of listhesis between PLIF and TLIF groups preoperatively (p = 0.190) and postoperatively (p = 0.208). In both groups, the spondylolisthesis-related deformities of patients were significantly corrected after surgery (p < 0.001). CONCLUSION: PLIF and TLIF techniques have similar radiological results in restoring the sagittal spinopelvic balance in patients with degenerative spondylolisthesis. Both techniques are good options to achieve reduction and fusion in patients with degenerative spondylolisthesis, but have no advantage over each other for restoring spinopelvic balance. LEVEL OF EVIDENCE: Level III, Therapeutic study.

RESUMEN

OBJECTIVE: The aim of the present study was to compare calcium sulfate (CAS) and polymethylmethacrylate (PMMA) bone cements used for the augmentation of a failed pedicle screw with biomechanical pull-out strength (POS) testing. METHODS: Thirty lumbar vertebrae were harvested from 6 calves and bone mineral densities (BMD) were measured. Primary polyaxial pedicle screws were randomly inserted and pulled out and the POSs of the specimen were recorded. For revision, specimens were randomly assigned to the CAS-augmented pedicle screws group (Group 1) or PMMA-augmented pedicle screw group (Group 2). Pull-out tests were repeated to compare both groups. RESULTS: Mean BMD of the specimens was 1.006 ± 0.116 g/cm(2). There were no statistically significant differences between BMD results of the two groups (p=0.116). For Group 1, mean POS of primary screws was 2,441.3 ± 936.4 N and was 2,499.5 ± 1,425.1 N after CAS augmentation, demonstrating no statistically significant difference (p=0.865). In Group 2, mean POS of the primary screws was 2,876.6 ± 926.6 N and significantly increased to 3,745.5 ± 1,299.2 N after PMMA augmentation (p=0.047). There was also a significant difference in mean POS between the CAS and PMMA groups (p=0.026). CONCLUSION: Although CAS augmentation facilitates a revision screw POS as strong as that of primary screws, it is not as strong as PMMA augmentation.

RESUMEN

OBJECTIVE: The aim of this study was to examine the effect of oophorectomy in the formation of epidural fibrosis in a rat laminectomy model. METHODS: Thirty-six 12-month-old adult female Sprague-Dawley rats were used in this study. Rats were evenly divided into two groups; oophorectomized and sham-operated. Bilateral oophorectomy was performed on the 18 rats in the oophorectomized group. Three weeks after oophorectomy, rats in both groups underwent complete bilateral laminectomy at the L2 and L3 vertebral levels. Rats were divided into 3 equal groups and sacrificed in groups of 4 at the 4th, 8t, and 12th weeks postoperatively and the lumbar spine excised en bloc, fixed and decalcified. Sections were stained with hematoxylin and eosin and Masson's trichrome were used to evaluate epidural fibrosis, acute inflammation, chronic inflammation, and vascular proliferation. RESULTS: The mean histological sum grade of the epidural fibrosis was greater in the oophorectomized group (p>0.05). CONCLUSION: Endogenous estrogen could have an effect on epidural fibrosis formation after lumbar laminectomy in rats.

RESUMEN

An unusual case of a double-level isthmic spondylolisthesis of the lumbar spine in a 38-year-old female was described. The patient had been suffering from low back pain for 8 years and did not respond to conservative treatment. Her medical examination revealed that grade II isthmic spondylolisthesis was present both at L-4 to L-5 and at L-5 to S-1. The patient was managed by surgical treatment. After the reduction of lysthesis with posterior instrumentation, posterior lumbar interbody fusion (PLIF) technique was performed for double level. At a recent follow-up, 1 year after the surgery, the symptoms of the patient were completely resolved, reduction was preserved, and fusion was achieved. PLIF with posterior instrumentation and reduction seems to be a convenient treatment option in the treatment for double-level spondylolisthesis.

RESUMEN

OBJECTIVE: The purpose of this study was to analyze the relation between tendon integrity and functional results following the arthroscopic treatment of small- and medium-sized rotator cuff tears. METHODS: Arthroscopic repair was performed on 26 consecutive patients (21 women, 5 men;mean age: 55.9 years; range: 33-72 years) with small- and medium-sized tears of the supraspinatus tendon. Patients were postoperatively evaluated at 12 and 24 months using the Constant and UCLA functional outcome scores and ultrasound examinations. RESULTS: The supraspinatus tendon did not heal in nine patients (34.6%) and was partially healed in three (11%), 12 months after surgery. Mean postoperative Constant and UCLA scores of these patients were 73.1 and 27.8, respectively, which were not significantly different from those with an intact tendon on the final follow-up (Constant: 78 and UCLA: 30; p=0.107 and p=0.164). Both rating systems reflected significant improvement with treatment (p<0.01). The mean age of patients with a re-tear was 66.8 years, which was significantly higher than those with an intact repair (54 years; p<0.01). CONCLUSION: The arthroscopic repair of small and medium-sized supraspinatus tendon tears yields good long-term results independent of tendon integrity. Healing potential may be decreased with increased age.

RESUMEN

OBJECTIVES: The purpose of this study to compare clinical and isokinetic results of patients who underwent biceps tenotomy or tenodesis for chronic tenosynovitis. METHODS: Arthroscopic biceps tenotomy, arthroscopy assisted or arthroscopic biceps tenodesis were done in 20 patients who had diagnosis of chronic tenosynovitis and in whom conservative treatment was not helpful. Rotator cuff repair and acromioplasty was performed in 18 patients and acromioplasty alone in two patients in addition to biceps surgery. Arthroscopic biceps tenotomy was done in 10 patients (5 female, 5 male; mean age 63, range 53-75), 10 patients underwent tenodesis out of which arthroscopy assisted biceps tenodesis was done in 8 patients and all arthroscopic biceps tenodesis was done in 2 patients (4 female, 6 male; mean age 57, range 49-66). All patients were evaluated with Constant and UCLA scores preoperatively and postoperatively. The average follow-up of the patients 3,1 years (between 1-8 years). Isokinetically elbow flexion and forearm supination were compared using the Cybex (Biodex 3, Cybex Biomedical System, NY, USA) machine. Pre-operative results of each group were compared with the postoperative results, using Mann-Whitney U test. RESULTS: Preoperative average constant scores of tenotomy group were 64.40, whereas postoperative scores were 89.50 (p=0.002), and preoperative average constant scores of tenodesis group were 62.80, whereas postoperative scores were 86.70 (p=0.003). Preoperative average UCLA scores of tenotomy group were 23.20 whereas postoperative UCLA scores 22.60 (p=0.003), preoperative average UCLA scores of tenodesis group were 30.00 whereas postoperative UCLA scores was 29.20 (p=0.004). In both groups statistically significant improvement of UCLA and Constant scores was detected. Comparison between Constant, UCLA scores and isokinetic measurements of both groups showed no statistically significant difference (p>0.05). No complication was noted. CONCLUSION: In the treatment of chronic tenosynovitis, biceps tenodesis and tenotomy of long head of biceps showed similar clinical, functional, isokinetic and cosmetic results. No Popeye deformity was seen in the tenotomy group.

RESUMEN

OBJECTIVES: The aim of this study was to determine the relation between the percent of canal compromise and success rate of epidural steroid injection (ESI) in patients with symptomatic lumbar herniated intervertebral discs. METHODS: Patients with lumbar herniated intervertebral disc suffering from leg pain and treated with ESI were selected. The axial magnetic resonance (MR) image showing the largest canal compromise by the herniated disc was selected for measurements. The canal area and disc herniation area measurements were calculated from the total number of pixels per cross-sectional area, multiplied by a scan correction factor, mm2/pixel. The percent canal compromise was obtained by the disc herniation area divided by the canal cross-section area, multiplied by 100. For pain assessment, visual analog scale (VAS) was used before (pre-injection VAS) and a month after ESI (post-injection VAS). Demographic data, duration of symptoms, and location and type of herniation were also noted. RESULTS: 39 patients (14 male, 25 female) were included in this study. The mean age was 50.2±11.6 years (27-76). Twenty-one cases (51%) also had back pain. The mean percent canal compromise ratio was 36.1±2.4%. The mean duration of symptoms was 19.4±6.6 months. The post-injection VAS was significantly decreased when compared with pre-injection VAS (p<0.0001), and this significance was related with the duration of symptoms being <3 months (p=0.021). There was also a significant negative correlation between percent canal compromise and post-injection VAS (p=0.042). However, there was no correlation between post-injection VAS and age, sex, or location or type of herniation (p>0.05). CONCLUSION: It has been demonstrated that higher benefits of ESI were achieved in patients with short duration of symptoms and high percent of canal compromise.

RESUMEN

OBJECTIVES: The aim of this study is to evaluate both the technical problems of surgery and the clinical and radiologic outcomes of patients treated with unicondylar knee arthroplasty. PATIENTS AND METHODS: Forty-one unicondylar knee prosthesis were performed in 40 patients (3 males, 37 females; mean age 58.2 years; range 44 to 76 years) diagnosed with unicompartmental knee osteoarthritis. Technical problems encountered during surgery were noted. For evaluation of clinical outcomes, the Hospital for Special Surgery (HSS) knee score and WOMAC score were used. Radiologic evaluations were performed using the Oxford Knee Group criteria. RESULTS: The radiologic evaluation determined there was more than 10 degrees varus-valgus malposition in eight patients, more than 2 mm medial tibial overhang in seven patients, the insertion of a femoral component in extension in one patient, and joint distraction in one patient. The patient with joint distraction underwent a total knee replacement after six months because of progressive pain. The mean HSS knee score improved 21 points; perfect results were obtained in 33 patients and good results in seven patients. The mean postoperative WOMAC score was reduced by 18 points, with perfect results in 33 patients, good results in six patients and a moderate result in one patient. The mean follow-up was 19 months (range 9-42). CONCLUSION: Unicondylar knee arthroplasty is a surgical treatment method with a long-term recovery and high frequency of technical faults. Minor errors diagnosed on radiographs do not have an effect on early clinical results. Unicondylar knee arthroplasty is a good alternative surgical technique for appropriately selected patients with medial unicompartmental knee osteoarthritis.

RESUMEN

Debridement is warranted for the treatment of nontuberculous spondylodiscitis in case of neurological compromise, deformity, instability, abscess formation, extensive destruction, intractable pain or failure of medical management. The additional use of instrumentation is still controversial, but might fight infection and yield stability. The purpose of this retrospective study was to evaluate the outcome of 16 cases of non-tuberculous thoracic or lumbar spondylodiscitis treated with anterior debridement and reconstruction (tricortical graft or titanium mesh cage), combined with single-stage posterior instrumentation and grafting. The pathogens identified were: Brucella (5), coagulase-negative Staphylococcus aureus (4), Staphylococcus aureus (3), unidentified (4). All 16 infections resolved without recurrence. Bony union was obtained in all cases. Fourteen out of 16 patients (87.5%) were completely relieved of pain and fully active, an excellent result according to Macnab's criteria; the other two patients obtained a good result. All 7 patients who had a neurological deficit improved. There were two superficial infections, which healed with debridement and antibiotics. A single iliac vein injury was primarily repaired. In conclusion, the proposed technique is an effective and safe treatment for pyogenic spondylodiscitis, if surgery is mandatory.

RESUMEN

A 60-year-old woman complained of low back pain radiating to both buttocks and to the anterior aspect of the left thigh. MRI showed a left posterolateral epidural mass at the L1-L2 level. An epidural abscess was suspected, but the biochemistry was normal. Excision yielded complete relief of symptoms. Pathological examination demonstrated that the specimen was a migrated disc fragment. The authors found 29 other cases of disc migration to the posterior epidural space; two of these were at the thoracic level. Eleven of the 27 lumbar cases (40%) were complicated with Cauda Equina Syndrome (CES). MRI is the method of choice to make the diagnosis. The differential diagnosis includes tumour, haematoma and abscess.

RESUMEN

INTRODUCTION: Biphasic calcium phosphate (BCP) has proved to be an effective bone substitute, but it's effectiveness and remodeling potential in open wedge high tibial osteotomy (OWHTO) has not been analyzed yet. This study sought to evaluate the bone healing and remodeling potentials of BCP granules using a radiographic rating system in biplanar OWHTO. MATERIALS AND METHODS: Fifteen patients (15 knees) underwent biplanar OWHTO. Bone gaps were filled with BCP granules. For radiographic evaluation, remodeling was divided into four phases. Phase 1 was accepted as rounded osteotomy sites, with clear distinction between BCP and bone, phase 2 was accepted as whitened osteotomy sites, with distinction between BCP and bone still visible, phase 3 was accepted as distinction between BCP and bone not visible and cloudy bone formation and phase 4 was accepted as full reformation of BCP granules (4A-BCP visible, 4B-disappearence of BCP) with no sign of osteotomy. Bone union was confirmed with clinical (full weight bearing without pain) and radiographic evaluation (cortical bridging callus on radiographs and phase 3 or greater remodeling). The time to full remodeling and the starting point of the consolidation on anteroposterior radiographs were noted. Complications were also noted at each clinical follow-up. RESULTS: Mean follow-up was 27.2 months. The mean age was 55.8 years. At clinical follow-up, there were no wound healing problems, no loss of corrections, no infections, and no complications. All osteotomies successfully healed. According to the radiologic classification system, at the 6th week, 73.3% (11/15) of patients were in phase 1 and the remaining 26.7% (4/15) were in phase 2. At 12-month follow-up, 46.7 (7/15) of the patients were still in phase 3. After 2 years, all radiographs showed to be in phase 4A. Radiographic union was noted to progress from lateral to medial and finally central. CONCLUSIONS: BCP can be successfully used as a bone substitute. The radiographic remodeling and consolidation process of BCP was found to be different from that of beta-tricalcium phosphate. In our patients with more than 2 years of follow-up, BCP granules did not completely remodel. As a result, this clinical study demonstrated that calcium phosphate granules containing hydroxyapatite had a long period of "creeping substitution" that lasts longer than 2 years.

RESUMEN

We investigated whether there is a correlation between coronal plane correction magnitude and tibial slope in patients treated with medial open wedge high tibial osteotomy (OWHTO) and also measured changes in patellar height. Thirty-four knees treated with for varus deformities were retrospectively reviewed and the follow-up period of the patients was averaged 24.1 months. Preoperative and postoperative measurements of the Hospital for Special Surgery (HSS) score, Insall-Salvati index, posterior tibial slope angle, mechanical axis deviation, proximal medial tibial angle (PMTA) was used to determine. All patients had a significant increase in their HSS score postoperatively (P < 0.0001). There was no significant correlation between the differences in patellar heights (P = 0.368). The mechanical axis deviation was altered by a mean of 25.5 +/- 10.9 mm and the difference was statistically significant (P < 0.05). The mean posterior tibial slope angle on preoperative radiographs was 9.0 +/- 5.1 degrees ; on postoperative radiographs it was 11.7 +/- 5.7 degrees and the difference was statistically significant (P < 0.007). Seventeen knees (50%) demonstrated postoperative posterior tibial slope angle increases; 7 knees (21%) had a decrease in this angle, while 10 knees (29%) showed no change. Statistical analyses revealed that the mechanical axis deviation was not correlated with change in tibial slope (P = 0.837). Although we could not find a correlation between tibial slope change and the amount of coronal correction, 50% of our patients demonstrated increased tibial slope.

RESUMEN

BACKGROUND: Hip fractures in patients with end-stage renal disease are associated with frequent complications. This study analyzed clinical outcomes for patients on chronic hemodialysis who sustained hip fractures and were treated with a variety of fracture repair methods. METHODS: Twenty-nine patients with thirty-two hip fractures were analyzed in three groups. Group 1 consisted of eleven hips in eleven patients with an intertrochanteric fracture that was treated with internal fixation; Group 2, thirteen hips in ten patients with a femoral neck fracture that was treated with screw fixation; and Group 3, eight hips in eight patients with a femoral neck fracture that was treated with hemiarthroplasty. The outcomes and early and late complications were recorded for each group. Survivorship analysis was performed, and the mortality and complication rates for the groups were compared. RESULTS: In Group 1, eight complications occurred in six hips and nonunion developed in five hips. In Group 2, sixteen complications developed in eleven hips. Union was achieved in two of the thirteen hips, nine hips had nonunion, and two hips had osteonecrosis develop. In Group 3, only one hip had early complications, there were no late complications, and three patients died. The mean duration of follow-up was twenty-three months, and the overall mortality rate was 45%. There were no significant differences among the groups with respect to the cumulative survival proportions. Regression analysis of age, sex, and total hemodialysis duration in relation to mortality risk revealed that only age had a significant influence on mortality (p = 0.019). CONCLUSIONS: Surgical treatment of hip fractures in patients with end-stage renal disease who are on chronic hemodialysis is associated with frequent complications and a high mortality rate. Osteosynthesis is an acceptable option for treating intertrochanteric fractures and nondisplaced femoral neck fractures, but displaced femoral neck fractures should be treated with hemiarthroplasty.

RESUMEN

BACKGROUND: Necrotizing fasciitis is a rare and often fatal soft-tissue infection. Prompt diagnosis and immediate aggressive surgical debridement of all compromised tissues are critical to reducing morbidity and mortality in these rapidly progressive infections. The purpose of this study was to analyze the clinical presentation and evaluate factors that determine mortality associated with this uncommon surgical emergency. METHODS: The study retrospectively investigated the medical records of 22 patients who were diagnosed and treated for necrotizing fasciitis of the lower extremity, 14 of whom had involvement of the foot (nine patients) or foot and ankle (five patients) at our hospital. The data collected for each of the 22 patients were age, sex, underlying systemic factors, location of infection, duration of symptoms, portal of entry of infection, initial diagnosis on admission, physical, radiographic and laboratory findings, microbiological cultures, the type of therapy used (debridement or amputation), treatment outcome, and number of days in the hospital. RESULTS: A total of 23 extremities of 22 consecutive patients with necrotizing fasciitis who underwent surgical debridement or amputation were retrospectively reviewed. Radical surgical debridement was done in 16 extremities initially, and this treatment was repeated a mean of two times (range one to four debridements) to completely remove all the necrotic tissue. Nine patients (41%) required below-knee or above-knee amputation. There were three deaths, one related directly to sepsis and organ failure, one due to gastrointestinal hemorrhage, and one caused by pulmonary embolism. There were no significant differences between patients who had the amputations and those who did not with respect to mortality rate or age (p = 0.538 and p = 0.493, respectively). Those who died were significantly older than the survivors (p = 0.038). CONCLUSIONS: The diagnosis of necrotizing fasciitis should be considered for any individual who has unexplained limb pain, especially if that person has diabetes mellitus or chronic liver disease. There was no difference in mortality rates between patients with or without amputation. The primary treatment is early and aggressive debridement of involved skin, subcutaneous fat, and fascia.

RESUMEN

Pain at the first metatarsophalangeal (MTP) joint can result from inflammation, chondromalacia, flexor hallucis brevis tendinitis, osteochondritis dessecans, fracture of a sesamoid bone, avascular necrosis of sesamoids, inflamed bursae, intractable keratoses, infection, sesamoiditis, gout arthropathy, and rheumatoid arthritis. Congenital absence of a sesamoid bone is extremely rare. We present a 17-year-old male patient with pain at the plantar aspect of the right MTP joint associated with congenital absence of the medial sesamoid. There was tenderness and the range of motion was minimally restricted. He described the pain as necessitating changes in his social life. On radiographs, the medial hallucial sesamoid was absent on the right side. The MTP joint was also evaluated using magnetic resonance imaging (MRI). A metatarsal pad was prescribed and the patient was satisfied with the treatment at the 2 months follow-up period. MRI revealed no pathological tissue at the medial sesamoid site. Hallucial sesamoids absorb pressure, reduce friction, protect the tendons, act like a fulcrum to increase the mechanical force of the tendons, and provide a dynamic function to the great toe by elevating first metatarsal head. Congenital absence of these bones is very rare but we must consider it in a patient with MTP joint pain.

RESUMEN

A 53-year-old man presented with a 12-year history of a progressively growing solid mass at his left shoulder. A 39x30x18-cm and 14.440-kg mass including the scapula was resected. Pathologic features were specific for chondroblastoma. During the 36-month follow-up, he had multiple inoperable metastatic lesions in his lungs. Histology of the transthoracic needle biopsy showed the metastatic nodules had features specific for chondroblastoma; however, the microscopic features additionally had hyperchromasia and increased mitotic activity in some areas. In the English literature, there are a few cases of chondroblastoma located in the scapula. It is exceptional to see this lesion in the sixth decade of life and with pulmonary metastases.

RESUMEN

We report the case of a 41-year-old man with right ankle pain and swelling who had an intraosseous talar ganglion in the medial part of talar dome. A surgical procedure was performed using the 3-portal arthroscopic approach. The softened chondral surface was removed and the content of the cyst was discharged arthroscopically. The sclerotic rim was abraded until the bleeding spongious layer was seen. A grafting procedure was also performed arthroscopically. A trocar was introduced into the defect from the superomedial portal. Autografts were impacted using a cylindrical rod through the trocar into the defect. The clinical and radiologic results at the 1-year follow-up were satisfactory. We encountered no complications postoperatively. We conclude that arthroscopic debridement and grafting of an intraosseous ganglion adjacent to the articular surface may be a better option compared with open surgery.
