Background: Our purpose was to evaluate a custom reverse total shoulder arthroplasty glenoid baseplate for severe glenoid deficiency, emphasizing the challenges with this approach, including short-term clinical and radiographic outcomes and complications. Methods: This was a single-institution, retrospective series of 29 patients between January 2017 and December 2022 for whom a custom glenoid component was created for extensive glenoid bone loss. Patients were evaluated preoperatively and at intervals for up to 5 years. All received preoperative physical examinations, plain radiographs, and computed tomography (CT). Intra- and postoperative complications are reported. Results: Of 29 patients, delays resulted in only undergoing surgery, and in three of those, the implant did not match the glenoid. For those three, the time from CT scan to implantation averaged 7.6 months (range, 6.1-10.7 months), compared with 5.5 months (range, 2-8.6 months) for those whose implants fit. In patients with at least 2-year follow-up (n=9), no failures occurred. Significant improvements were observed in all patient-reported outcome measures in those nine patients (American Shoulder and Elbow Score, P<0.01; Simple Shoulder Test, P=0.02; Single Assessment Numeric Evaluation, P<0.01; Western Ontario Osteoarthritis of the Shoulder Index, P<0.01). Range of motion improved for forward flexion and abduction (P=0.03 for both) and internal rotation up the back (P=0.02). Pain and satisfaction also improved (P<0.01 for both). Conclusions: Prolonged time (>6 months) from CT scan to device implantation resulted in bone loss that rendered the implants unusable. Satisfactory short-term radiographic and clinical follow-up can be achieved with a well-fitting device. Level of evidence: III.

Background: Down's syndrome, or trisomy 21, is the commonest congenital chromosome anomaly. With improvement in medical care, these patients increasingly reach adulthood in spite of their physical maldevelopment and mental retardation. And, the number of those who required general anesthesia for dental treatment is increasing. Methods: We reviewed the 26 cases of 22 patients with Down's syndrome who underwent outpatient general anesthesia for dental treatment at the clinic for the disabled in Seoul National University Dental Hospital. Results: The mean age was 22 years. They all had severe mental retardation and some had congenital heart anomaly, epilepsy, hypothyroidism, acute leukemia, autism, cleft palate, and chronic renal failure. For anesthesia induction, 4 cases was needed physical restriction, but others showed good or moderate cooperation. Drugs used for anesthesia induction was thiopental (17 cases) and sevoflurane (9 cases). All patients received nasotracheal intubation and 3 cases needed difficult airway management. Mean total anesthetic time was $166{\pm}60$ min and staying time at PACU was $92{\pm}48$ min. There was no death or long term hospitalization because of severe complications. Conclusion: If general anesthesia is needed, pertinent diagnostic tests and workup about anomaly, and appropriate anesthetic planning are essential for safety.

Objective : Craniovertebral junctional anomalies constitute a technical challenge. Surgical opening of atlantoaxial joint region is a complex procedure especially in patients with nuchal deformity like basilar invagination. This region has actually very complicated anatomical and functional characteristics, including multiple joints providing extension, flexion, and wide rotation. In fact, it is also a bottleneck region where bones, neural structures, and blood vessels are located. Stabilization surgery regarding this region should consider the fact that the area exposes excessive and life-long stress due to complex movements and human posture. Therefore, all options should be considered for surgical stabilization, and they could be interchanged during the surgery, if required. Methods : A 53-year-old male patient applied to outpatients' clinic with complaints of head and neck pain persisting for a long time. Physical examination was normal except increased deep tendon reflexes. The patient was on long-term corticosteroid due to an allergic disease. Magnetic resonance imaging and computed tomography findings indicated basilar invagination and atlantoaxial dislocation.The patient underwent C0-C3-C4 (lateral mass) and additional C0-C2 (translaminar) stabilization surgery. Results : In routine practice, the sites where rods are bound to occipital plates were placed as paramedian. Instead, we inserted lateral mass screw to the sites where occipital screws were inserted on the occipital plate, thereby creating a site where extra rod could be bound.When C2 translaminar screw is inserted, screw caps remain on the median plane, which makes them difficult to bind to contralateral system. These bind directly to occipital plate without any connection from this region to the contralateral system.Advantages of this technique include easy insertion of C2 translaminar screws, presence of increased screw sizes, and exclusion of pullout forces onto the screw from neck movements. Another advantage of the technique is the median placement of the rod; i.e., thick part of the occipital bone is in alignment with axial loading. Conclusion : We believe that this technique, which could be easily performed as adjuvant to classical stabilization surgery with no need for special screw and rod, may improve distraction force in patients with low bone density.

Background: The gastrocnemius (GCM) is one of the lower extremity muscles that tend to tighten easily. GCM tightness results in limited ankle dorsi-flexion (DF), especially when the knee joint is fully extended. Joint flexibility is determined by the morphological and physiological characteristics of joints, muscles, tendons, and ligaments. Impaired joint flexibility can be attributed to increased susceptibility to muscle injury. High-frequency diathermy is clinically used to reduce pain and muscle tightness and to improve limited range of motion. Objects: This study aimed to investigate the immediate effects of high-frequency therapy in subjects with GCM tightness. Methods: The study was designed as a one-group before-after trial. The subjects included 28 volunteers with GCM tightness (an active ankle DF angle of less than 12°) without any known neurological and musculoskeletal pathologies in the ankle and calf areas. WINBACK Transfer Electrode Capacitive and Resistive Therapy equipment was used to apply high-frequency therapy to the subjects' GCMs for 10-15 minutes. The pennation angle and the fascicle length of the GCM were measured using ultrasonography. The flexibility of the ankle joint, peak torque to the passive ankle DF (Biodex), and soft tissue stiffness (MyotonPRO) were also measured. Results: The pennation angle was significantly decreased following the treatment; however, no significant difference in the fascicle length was found (p < 0.05). The flexibility was significantly increased and both the passive peak torque to passive ankle DF and the soft tissue stiffness significantly decreased (p < 0.05). Conclusion: High-frequency therapy is immediately effective for improving the muscle's architectural properties and functional factors in subjects with GCM tightness. Further longitudinal clinical studies are required to investigate the long-term effects of high-frequency therapy on subjects with GCM tightness from various causes.

Deer Antler has been known for its traditional oriental medicinal properties and has been widely used to promote growth, boost immune function, treat blood loss and chronic joint pain. Recent study showed imported (New Zealand) Deer Antler was beneficial in reducing the side effects of cancer treatments. However, there was no intervention study conducted on the effect of Korean Deer Antler on reducing the oxidative stress to patients with diabetes. One of the sensitive ways to measure endogenous oxidative stress is by measuring cellular DNA damage using single cell gel electrophoresis (COMET assay). This study was conducted to investigate the possible beneficial effect of commercial Deer Antler drink (provided by Chung-yang Deer Farm) on lymphocyte DNA damage and blood glucose of diabetic patients. Ten patients (4 men, 6 women) participated in the study and consumed 2 pouches of Deer Antler drink every day for 20 days. Blood was collected on the morning before and after the intervention for lymphocyte isolation and blood glucose analysis. Both systolic and diastolic blood pressure showed a tendency to decrease but did not reach statistical significance after the trial. Blood glucose level was not affected by the supplementation. After the intervention, over 50% reduction were noted in the cellular DNA damage, expressed as tail length (TL) and tail moment (TM: tail length ${\times}$ percent tail DNA) . Although we did not obtain beneficial effect on lowering blood glucose levels in the patients, this results suggest that Deer Antler may initially act in protecting endogenous DNA damage in short-term experiment.

Background & Object: Ankylosing spondylitis (AS) is a chronic inflammatory disease that causes ankylosis and deformation of axial joints. Since current medicine cannot cure the disease yet, alleviating pain and preventing deformation with medications are the main therapy for patients with AS. The key medications for these purposes include nonsteroidal anti-inflammatory drugs (NSAIDs), and tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) inhibitors. This study aims to analyze prescribing patterns of AS patients in South Korea. Method: National Patients Sample data compiled by the Health Insurance Review and Assessment Service from 2013 was analyzed. Patients with AS were identified with Korean Standard Classification of Diseases code-6, which was M45. The rates of prescription, discontinuation, and switching ingredients were calculated for each medication during 2013. Results: Total number of patients was 655, and most of them were male (n = 514, 78.5%). Of all age groups, the proportion of 30-40 year old patients was the greatest (35.1%). The most utilized drug class was NSAIDs (82.4%). Less than half of patients were prescribed $TNF-{\alpha}$ inhibitors (n = 212, 32.4%). Meloxicam, aceclofenac, and celecoxib were the most frequently prescribed NSAIDs. In case of $TNF-{\alpha}$ inhibitors, adalimumab, etanercept and infliximab were the top three most prescribed drugs. Although not recommended by the current practice guideline, significant proportions of patients were identified using disease modifying anti-rheumatic drugs (DMARDs). Conclusion: Considering the current practice guideline and previous studies about the efficacy, the use of DMARDs should be reduced and medical insurance term in South Korea should be re-examined.

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.

Purpose: To evaluate clinical results of the 5th proximal metatarsal intraarticular fracture (Zone I) with displacement treated operatively and to evaluate predisposing factors of the 5th proximal metatarsal fracture (Zone I). Materials and Methods: 11 patients treated for the 5th proximal metatarsal fracture (Zone I) operatively and 10 patients treated conservatively between Jan 2003 and Dec 2005, were followed for more than one year. Functions were graded by AOFAS foot scoring system and union time and postoperative complications were also evaluated. Calcaneal pitch angle was also evaluated. Results: Clinically there were no much difference in results. Clinical points were 94.5 in the operative group and 92.3 in the conservative group. At the last follow-up, the radiographic results showed union in all cases. During the follow-up period, there were no significant complications. But in the conservative group, displaced fracture with calcaneal pitch angle over 30 degree tends to show delayed union and time to loss of pain tends to be prolonged. Conclusion: Calcaneal pitch angle is thought to predisposing factor for 5th metatarsal base fracture. Operative treatment is viable option for the 5th proximal metatarsal intraarticular fracture with displacement and with calcaneal pitch angle over 30 degree. In cases of cavovarus foot deformity, we think operative treatment should be considered with deliberation and long term follow-up study for peroneal tendinopathy should be needed.

The pain, swelling of salivary glands and dry mouth are not infrequent complication of the high dose radioiodine treatment in the patients with differentiated thyroid cancer. The purpose of this study was, by the dynamic salivary scintigraphy, to observe the change of the salivary function after the high dose $(150\sim200mci)$ radioiodine treatment. From May 1987 to April 1988, the dynamic salivary scintigraphy with 5mci of $^{99m}Tc-pertechnetate$ and gamma camera was performed before and 7 days after the radiolodine treatment in 7 patients with differentiated thyroid cancer. Just after the dynamic scintigraphy, the stimulation test with vitamin C solution of pH3.0 and poststirnulation scintigraphy were done, and the radioactivity uptake index, excretion fraction and salivary clearance after the stimulation were calculated for each gland. There was positive correlation between the radioactivity uptake index and excretion fraction after the stimulation. The salivary clearance after the stimulation was $18.96{\pm}8.95ml/min$ in the pretreatment state, and $14.37{\pm}7.7ml/min$ after the radioioine treatment. After the radioiodine treatment, the radioactivity uptake index, excretion fraction and salivary clearance after the stimulation were significantly reduced in the parotid glands, but only the excretion fraction was reduced in the submandibular glands. The more the pretreatment salivary clearance after the stimulation was, the % change after the treatment was smaller. Further studies on the relation between the radiation dose in the salivary glands and the change of their function, and the long-term observation for the recovery of function are expected.
