The natural course of lateral epicondylitis is widely regarded to be self-limiting within 1 year of symptom duration in 90% of all patients. The spectrum of treatments include simple ‘wait and see', bracing, physical therapy, corticosteroid injection, and recently some biologic injection such as autologous blood and platelet rich plasma. However, recalcitrant lateral epicondylitis which are not responding to conservative treatments can be treated with surgical treatment although much remains unclear regarding the ideal treatment. Debates surrounding open procedures are the management for the defect after resection of pathologic tissue, necessity of decortication, selective denervation procedure, etc. Since the trend is changing to minimal invasive surgery and arthroscopic release of extensor carpi radialis brevis tendon are becoming more popular these days, surgical tips and pitfall to obtain good results and avoid complications have been reported recently. Bipolar radiofrequency (RF)-based microtenotomy or percutaneous tendon release is another surgical procedures reported to be effective in lateral epicondylitis. However, there are some patients who present with persistent pain after surgical treatment. Thus, selection of ideal candidates for surgery, thorough evaluation of all pathologies prior to surgery, and adequate surgical procedures would be essential in the surgical treatment of lateral epicondylitis.

If surgical treatment is not given to the blow-out frature at proper time after trama, diplopia due to motion limitation of globe and poor cosmesis by progressing enophthalmos may troubles in everyday life. But in spite of large fracture andsevere diplopia, these symptoms may be improved with only conservative treatment. From January 1990 to June 1997 authors reviewed 192 consecutive patients with orbital wall fracture. 1997 authors reviewed 192 consecutive patients woth orbital wall frature. Among them, 123 patients who treated with conservative method and 69 patients with surgery. Both conservative treatment group and surgical group had similar demographics in sex, age, cause of trauma, associated symptoms and location of orbital wall fracture. But incidence of extraocular muscle entrapment was more common in surgical treatment group than conservative at 2 months after trauma. In principle blow-out fracture should be repaired surgically for maintenance of normal orbital wall stracture. In addition to improvement of diplopia that can be achieved by conservative treatment, there are many complications such as anesthetic accident, persistant diplopia poeroperatively and scar formation in lower lid associated with surgical treatment of blow-out fracture. Therefore, restrictive application of surgical indication shoul be considered.

PURPOSE: To identify the structural integrity of the healing site after medial open wedge high tibial osteotomy (MOWHTO) in patients with a posterior root tear of the medial meniscus (PRTMM) and chondral lesion by second-look arthroscopy and to determine the clinical and radiological findings. MATERIALS AND METHODS: From August 2010 to June 2016, 52 consecutive patients underwent MOWHTO and arthroscopic examination without a chondral resurfacing procedure and meniscal treatment for PRTMM. Twenty-four patients were available for second-look arthroscopic evaluation. The mean follow-up period was 19.5 months (range, 5 to 46 months). Clinical evaluation was based on the Lysholm knee scores and Hospital for Special Surgery (HSS) scores. RESULTS: There were 5 lax healing, 6 scar tissue, 13 failed healing of PRTMM. Definite change of chondral lesion was not observed. The Kellgren-Lawrence grade did not improve according to the follow-up plain radiograph. The mean Lysholm score improved from 34.7 preoperatively to 77.1 at the last follow-up, and the mean HSS score significantly increased from 36.5 to 82.4. CONCLUSIONS: This study revealed a low rate of healing potency of PRTMM and chondral lesion after MOWHTO without any attempt for meniscal treatment or chondral resurfacing. The cartilage and healing status of PRTMM was not associated with improved clinical outcomes and radiological findings.

OBJECTIVE: To analyze the effect of vertebroplasty on costal pain which develops following osteoporotic thoracic compression fractures (OTCFs). METHODS: The authors reviewed the medical records of 35 patients who underwent vertebral augmentation for the treatment of OTCFs over a five year period. The patients were divided into two groups: the costalgia group included patientswho had costal pain after a vertebral fracture and the non-costalgia group included patients without costalgia. To evaluate the effect of vertebroplasty on costal pain and factors related to costal pain, several factors including: vertebral body fracture type, pedicle injury, bone mineral density, the fracture level and clinical outcome were confirmed with magnetic resonance imaging and chart reviews. RESULTS: Among 35 patients, ten patients (28.6%) complained of costal pain with back pain. Only five of the ten patients (50%) had improved costal pain after a vertebroplasty. In the remaining 5 patients, the costal pain was improved through the use of medication including pain killers or a costal block during the follow-up period. Although the incidence of wedge deformity in the costal group was low(10%), there was no significant relationship to the incidence of costal pain statistically. Pedicle injury, bone mineral density and the fracture level had no significant relation to costal pain. CONCLUSION: The patients with wedge type, OTCFs may have a low incidence of costal pain as compared to those patients with bi-concave and crush deformities. The vertebroplasty effect on costal pain may not be effective. Therefore, before doing vertebroplasty, the surgeon should advise patients of this potential outcome in those treated for OTCFs.

Intracytoplasmic sperm injection (ICSI) recently has been utilized widely as the most successful technique to overcome the unfertilization problem in cases of severe male infertility in couples who could not be treated by conventional IVF. Recently, indications of ICSI have been extended further and more fertilized oocytes become available. Thus, it is necessary to examine the efficiency of freezing the surplus embryos obtained from ICSI. We compared the survival rate and the future outcome of cryopreserved embryos obtained either after conventional IVF or ICSI during the same period. After ICSI or IVF, five best-quality embryos from each patient were transferred in the stimulation cycle and the surplus pronuclear (PN) stage oocytes or multicellular embryos were cryopreserved by slow freezing protocol with 1,2-propanediol (PROH) as a cryoprotectant.4 total of 792 embryos from ICSI trial were thawed and 65.2% (516/792) survived. The survival rates of PN stage oocyte, multicellular embryo and PN + multicellular embryo were 63.5%, 68.2%, 64.0%, respectively. After 111 transfers, 34 pregnancies were achieved, corresponding to a clinical pregnancy rate of 30.6% per transfers. We thawed 1033 embryos from IVF trials and 57.5% (594/1033) survived. In IVF cycle, the survival rates of PN stage oocyte, multicellular embryo and PN + multicellular embryo were 58.2%, 65.2%, 40.2%, respectively. Thirty eight clinical pregnancies were established after 134 transfers, corresponding to a pregnancy rate of 28.4% per transfer The cleavage rate of thawed PN stage oocytes from ICSI trial (61.3%) was significantly higher than those from conventional IVF (53.4%). The developmental rates of good embryo (> or = grade II) in thawed PN stage oocytes obtained from conventional IVF and ICSI were 63% and 65%, respectively. We concluded that PN stage oocytes, multicellular embryos resulting from ICSI procedure can be successfully frozen/thawed with reasonable clinical pregnancy rates comparable to those of IVF.

Background: This review aimed to evaluate the effects of corticosteroid injections on Morton’s neuroma using an algorithmic approach to assess the methodological quality of reported studies using a structured critical framework. Methods: Several electronic databases were searched for articles published until April 2020 that evaluated the outcomes of corticosteroid injections in patients diagnosed with Morton’s neuroma. Data search, extraction, analysis, and quality assessments were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and clinical outcomes were evaluated using various outcome measures. Results: With 3–12 months of follow-up, corticosteroid injections provided satisfactory outcomes according to Johnson satisfaction scores except in two studies. Visual analog scale scores showed maximal pain reduction between 1 week and 3 months after injection. We found that 140 subjects out of 469 (29.85%) eventually underwent surgery after receiving corticosteroid injections due to persistent pain. Conclusions Corticosteroid injections showed a satisfactory clinical outcome in patients with Morton’s interdigital neuroma although almost 30% of the included subjects eventually underwent operative treatment. Our recommendation for future research includes using more objective outcome parameters, such as foot and ankle outcome scores or foot and ankle ability measures. Moreover, studies on the safety and effectiveness of multiple injections at the same site are highly necessary.

PURPOSE: Recently, cholangioscopy using narrow band imaging (NBI) has been used as a diagnostic modality for better visualization in hepatobiliary malignancies; however, there are few reports on it. Our aim is to evaluate the effectiveness of cholangioscopy using NBI in hepatobiliary malignancies. METHODS: Between January 2007 and December 2016, 152 cholangioscopies using percutaneous approach were conducted in total 123 patients. Among these, 36 patients were suspicious of hepatobiliary malignancies. Thirteen patients with an ambiguous margin on endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography (MRCP), for whom NBI tipped the balance in diagnosis of lesion and decision of lesion extent by adding NBI, were involved in our study. RESULTS: Underlying diseases were all malignant in 13 patients (11 bile duct cancers, 1 liver cancer, 1 pancreas cancer with common bile duct invasion). In 7 cases with papillary type tumor, minute superficial spreading tumor was detected by NBI more easily, and NBI provided a better visualization of tumor vessel and margin evaluation in 4 cases with infiltrative tumor. In 2 cases with mucin-hypersecreting tumor, NBI showed better penetration through the mucin and gave us a much clearer image. Nine patients ultimately underwent surgical resection. The margins predicted by NBI cholangioscopy were consistent with the pathological margins on the resected specimens. CONCLUSION: In conclusion, cholangioscopy using NBI is very useful for evaluation of suspected hepatobiliary malignancies with an ambiguous margin on ERCP or MRCP. It can give us an accurate pathologic mapping, and this information seems to be essential before deciding on a treatment strategy.
