When a revision surgery related with removal of failed interbody cage is required, going through the previous passage can lead to a higher risk of neurological deficits or incidental dural injuries. Recently, the lateral approach has become a popular method instead of the conventional anterior or posterior approaches. The lateral approach is also useful method to remove failed interbody cage previously placed and re-do interbody fusion with lower risks compared to revision surgery via previous passage. However, there is still some difficulty in retrieving the interbody cage from the intervertebral space because of no spacious passage, subsidence, and uncontrolled movable cage. In this study, we introduce our experience that we removed failed interbody cage more easily with only the simple additional steps of making a taphole and fixing the cage using a thread-tipped stick.

For undercorrected esotropia after bilateral medial rectus(MR) recession, we performed unilateral or bilateral MR rerecession, unilateral rerecession or marginal myotomy of the recessed medial rectus muscle combined with lateral rectus(LR) resection, or unilateral LR resection. The correction of deviation was 15 delta in unilateral 2.0mm MR rerecession. Bilateral 2.0mm MR rerecession corrected 20 to 25 delta of esodeviation, but undercorrection was noted in one case. With unilateral 2.0mm rerecession or marginal myotomy of the recessed medial rectus muscle combined with 5.5mm or 8.0mm LR resection, the correction of deviation was 26 to 29 delta, and there was no under- or overcorrection. The corrective effect of this procedure was therefore greater and more stable than that of bilateral 2.0mm MR rerecession. Unilateral 8.0mm LR resection performed 3 months after bilateral MR recession showed correction of 15 delta, whereas the same procedure performed 3 weeks after bilateral MR rerecession showed correction of 24 delta. Unilateral LR resection procedure seems to be more efficacious for residual esotropia if performed as soos as possible within 3 months after sufficient bilateral MR recession or rerecession.

We report here a case of a kidney transplant recipient in whom the ureter was initially implanted into the peritoneum. Excessive ultrafiltration volume and reversal of serum vs dialysate creatinine ratio when the patient was recommenced on continuous ambulatory peritoneal dialysis first suggested the diagnosis which was subsequently confirmed by a plain abdominal x-ray demonstrating placement of ureteric stent in the peritoneum. This rare complication was successfully corrected with surgical re-implantation of ureter into the bladder and 5 years later, the patient remains well with good graft function.

BACKGROUNDSevere acetabular bone deficiency is a major challenge in acetabular revision surgery. Most cases require reconstruction of the acetabulum with bone grafting and a reinforcement device. The purpose of this study was to evaluate the results of this procedure for severe acetabular bone deficiency in acetabular revision surgery.

METHODSThis study involved 12 patients (2 males and 10 females) with severe acetabular bone defects who underwent implantation of a reinforcement device (ring or cage) and bone grafting between February 2003 and October 2008. Using the Paprosky classification, 2 cases were Paprosky IIC, 6 were IIIA, and 4 were IIIB. The mean age at the time of surgery was 63.0 years (range, 46 - 78 years). During revision surgery, a reinforcement ring was implanted in 6 patients, and a cage in 6 patients. The clinical and radiographic results were evaluated retrospectively. The mean duration of follow-up was 37 months (range, 9 - 71 months).

RESULTSThe average Harris Hip Score improved from 35.2 preoperatively to 82.9 at the time of the final follow-up visit. The results were excellent in 8 hips (66.7%), good in 2 (16.7%), and fair in 2 (16.7%). Osteolysis was found in 1 case, but did not worsen. Three patients had yellow wound effusion, with healing after administration of dressing changes, debridement, and antibiotics. Dislocation occurred in a 62-year-old woman. Closed reduction was performed, and dislocation did not recur. There was no evidence of intraoperative acetabular fracture, nerve injury, ectopic ossification, aseptic loosening, or infection.

CONCLUSIONReconstruction with a reinforcement device and bone grafting is an effective approach to the treatment of acetabular bone deficiency in acetabular revision surgery, given proper indications and technique.

BACKGROUND: Surgical treatment of thoracic outlet syndrome (TOS) is necessary when non-surgical treatments fail. Complications of surgical procedures vary from short-term post-surgical pain to permanent disability. The outcome of TOS surgery is affected by the visibility during the operation. In this study, we have compared the complications arising during the supraclavicular and the transaxillary approaches to determine the appropriate approach for TOS surgery. METHODS: In this study, 448 patients with symptoms of TOS were assessed. The male-to-female ratio was approximately 1:4, and the mean age was 34.5 years. Overall, 102 operations were performed, including unilateral, bilateral, and reoperations, and the patients were retrospectively evaluated. Of the 102 patients, 63 underwent the supraclavicular approach, 32 underwent the transaxillary approach, and 7 underwent the transaxillary approach followed by the supraclavicular approach. Complications were evaluated over 24 months. RESULTS: The prevalence of pneumothorax, hemothorax, and vessel injuries in the transaxillary and the supraclavicular approaches was equal. We found more permanent and transient brachial plexus injuries in the case of the transaxillary approach than in the case of the supraclavicular approach, but the difference was not statistically significant. Persistent pain and symptoms were significantly more common in patients who underwent the transaxillary approach (p<0.05). CONCLUSION: The supraclavicular approach seems to be the more effective technique of the two because it offers the surgeon better access to the brachial plexus and a direct view. This approach for a TOS operation offers a better surgical outcome and lower reoperation rates than the transaxillary method. Our results showed the supraclavicular approach to be the preferred method for TOS operations.

PURPOSE: We reviewed the clinical features of intermittent exotropic patients who experienced recurrence after reoperation for intermittent exotropia, and identified the risk factors and prognoses. METHODS: The incidences, risk factors, treatment modalities, and prognoses of patients with recurrent exotropia were analyzed in 39 patients who underwent reoperation due to a relapse of exotropia after the first intermittent exotropia. RESULTS: Among 39 patients, 24 (61.5%) had recurrent intermittent exotropia and 15 patients had no recurrence with intermittent exotropia. There was no difference in the recurrence of intermittent exotropia with age, deviation, refraction, anisometropia, outward discrepancy, and the vertical deviation before the reoperation. However, when the first operation was performed with bilateral lateral rectus recession and the reoperation was performed with bilateral medial rectus resection or unilateral medial rectus resection, intermittent exotropia tended to recur more than when the first operation was performed with one eye with lateral rectus recession and medial rectus resection, followed by reoperation with the other lateral rectus recession and medial rectus resection (p < 0.05). In addition, an esodeviation <10 prism diopters, orthophoria, or exotropia on the first postoperative day showed a tendency to relapse more than an esodeviation >10 prism diopters (p < 0.05). CONCLUSIONS: The factors affecting recurrence after intermittent exotropia surgery involve surgical factors such as the surgical method and the postoperative overcorrection.

PURPOSE: To introduce and evaluate the long-term effectiveness of interrupted buried suture using non-absorbable material in involutional lower lid entropion. METHODS: A total of 105 adult involutional lower lid entropion patients (135 eyes) from January 2010 to January 2015 with or without the horizontal laxity, and without a history of previous surgical treatment were included. Exclusion criteria included patients with cicatricial entropion, epiblepharon, history of previous lower lid surgery, and follow-up period less than 3 months. The central and lateral areas below the lower lid margin and below the inferior tarsal margin were connected by non-absorbable interrupted buried suture. Results were analyzed by objective outcome using measurements from clinical photographs, subjective outcome using improvements of patients' symptom and cosmetic satisfactions. RESULTS: This study included 135 eyelids. Pre-operative distraction test revealed horizontal laxity in 37 eyes (27.4%). The mean age was 79.50 years and the mean period of follow-up was 34.51 ± 3.8 months. In 133 eyelids (98.5%), post-operative lid positions have everted. Score of symptom improvements were 9.44 (0 to 10 scale). 99 patients (94.3%) were cosmetically satisfied. No surgical complications were observed. Although we had two recurred cases (1.5%), one with horizontal laxity (2.7%) and one without horizontal laxity (1.0%), reoperation was not performed due to mild subjective discomfort. CONCLUSIONS: For patients with involutional entropion regardless of horizontal laxity, a simple interrupted buried suture method using non-absorbable suture material showed excellent long term results in very low recurrence rate and high cosmetic satisfaction.

BACKGROUND: The breast reconstruction using implant has been conducted widely. Many studies were presented to analyze the complications, but most of these studies were conducted with patients relatively short term period follow up. The authors studied with patients who were followed up at least five years. METHODS: Among the patients who were underwent breast reconstruction with implant from 1998 to 2007, 37 patients who met were followed up more than 5 years were selected in the study. Relationships between factors such as the operation methods, volume, type of surfaces of the implants, etc. and the complication rate or reoperation rate were analyzed. The level of satisfactory scoring was measured by patients' and 5 plastic surgeons. RESULTS: Complications were developed in 21 patients (65.6%) and 9 of them underwent reoperations. Infection was most common cause of complication. Implant removal was conducted to 7 patients, and 5 of them due to infection. The percentages of patients who received postoperative chemotherapy or radiotherapy in complication group and implant removal group were higher than the whole group whereas such correlation was not statistically significant. Direct Implant insertion has 50% of complication and 80% in permanent expander insertion and 73.7% of expanderimplant exchange. The average value of subjective score at last follow up was 4.2 points and the average value of objective score was 5.74. CONCLUSIONS: The incidence rate of complications was relatively high, and the final followup satisfaction score was low. This study should be helpful not only to select reconstruction methods, but also further studies to compare with other reconstruction methods.

The use of acetabular cup revision arthroplasty is on the rise as demands for total hip arthroplasty, improved life expectancies, and the need for individual activity increase. For an acetabular cup revision to be successful, the cup should gain stable fixation within the remaining supportive bone of the acetabulum. Since the patient's remaining supportive acetabular bone stock plays an important role in the success of revision, accurate classification of the degree of acetabular bone defect is necessary. The Paprosky classification system is most commonly used when determining the location and degree of acetabular bone loss. Common treatment options include: acetabular liner exchange, high hip center, oblong cup, trabecular metal cup with augment, bipolar cup, bulk structural graft, cemented cup, uncemented cup including jumbo cup, acetabular reinforcement device (cage), trabecular metal cup cage. The optimal treatment option is dependent upon the degree of the discontinuity, the amount of available bone stock and the likelihood of achieving stable fixation upon supportive host bone. To achieve successful acetabular cup revision, accurate evaluation of bone defect preoperatively and intraoperatively, proper choice of method of acetabular revision according to the evaluation of acetabular bone deficiency, proper technique to get primary stability of implant such as precise grafting technique, and stable fixation of implant are mandatory.
