Purpose: We wanted to evaluate the clinical and radiologic results of acetabular revision using the acetabular reinforcement ring and also the allograft impaction in the acetabulum having deficient bone stock. Material and Methods: Nineteen hips revision arthroplasty were performed in 18 patients (9 males and 9 females) with using an acetabular reinforcement ring and allograft between July 1993 and December 2003. The patients were followed for an average of 64 months (range: 24-153). The mean age at the time of arthroplasty was 59 years old (range: 34-76). The causes of revision were aseptic loosening of the acetabular component in 16 cases, severe progressive osteolysis around the acetabular component in 2 cases and Girdlestone state after infected total hip arthroplasty in one case. The acetabular deficiency was type II in 5 hips, type III in 13 hips, and type IV in one hip according to the AAOS classification. The clinical results were evaluated using the modified Harris hip score, and the radiologic results were evaluated by assessing the preoperative and serial follow-up radiographs. Results: The mean preoperative Harris hip score of 47 was improved to 86 points at the latest follow-up. Periacetabular osteolysis was found in 2 cases, which did not progress at follow-up. The anatomic hip center was restored after revision arthroplasty (p<0.05). Complications were dislocation in 2 cases, breakage of the hook of the Ganz ring in one case, heterotopic ossification in one case and femoral artery injury in one case. All cases showed stable fixation of the acetabular component and good remodelling of the impacted allograft. There was neither recurrence of dislocation nor progression of the acetabular component loosening on the radiographs. Conclusion: Acetabular revision with acetabular reinforcement ring and allograft impaction showed satisfactory clinical and radiologic results with restoration of the hip center and consolidation of the allograft.

A 62-year-old woman, who presented with dipolipia, was found to have a giant aneurysm of the right internal carotid artery. Gradual ligation of the right internal carotid artery was followed by nausea and vomiting 10 days after the complete ligation. Follow up MRI showed intraluminal thrombus formation of the aneurysm and right temporo-occipital infarction.

A 18-year-old girl, who presented with painful scalp mass on occipital region, was found in have a congential dermal sinus. At surgery, upon incision of the occipital muscle fascia, pus poket was encountered and it was connected with thickened occipito-cervical dura through the small foramen on midline occiptial bone. The pathogenesis and principles of management are briefly reviewed.

Rotator cuff tear is the most common cause of shoulder pain in middle-age and older people. Arthroscopic rotator cuff repair (ARCR) is the most common treatment method for rotator cuff tear. Early postoperative pain after ARCR is the primary concern for surgeons and patients and can affect postoperative rehabilitation, satisfaction, recovery, and hospital day. There are numerous methods for controlling postoperative pain including patient-controlled analgesia, opioid, interscalene block, and local anesthesia. Regional blocks including interscalene nerve block, suprascapular nerve block, and axillary nerve block have been successfully and commonly used. There is no difference between interscalene brachial plexus block (ISB) and suprascapular nerve block (SSNB) in pain control and opioid consumption. However, SSNB has fewer complications and can be more easily applied than ISB. Combination of axillary nerve block with SSNB has a stronger analgesic effect than SSNB alone. These regional blocks can be helpful for postoperative pain control within 48 hours after ARCR surgery.

This article evaluated levels of Estimated Average Requirements (EARs), Reference Nutrient Intakes (RNIs), and Acceptable Macronutrient Distribution Ranges (AMDRs) of protein using the recently revised Dietary Reference Intakes (DRIs) for Koreans (2020). Dietary protein requirements are based on amounts sufficient to satisfy physiological demands to accomplish nitrogen equilibrium. The same principle was applied to estimate EARs and RNIs, for adults in DRIs conducted in 2015 and 2020 in Koreans. EAR was estimated to be 0.73 g/kg body weight/day, according to data (0.66 g/kg body weight/day) obtained using the nitrogen balance method and adjusted by efficiency of protein use (90%). RNI was calculated as EAR increased by an amount equal to twice the standard deviation of an age group so as to cover 97.5% of the group and was found to be 0.91 g/kg body weight/day. For weaned infants, children, and adolescents, growth requirement was added to estimate EAR. In particular, growth requirement was adjusted by efficiency of protein use in the revised EAR, which led to higher EARs for weaned infants, children, and adolescents of both genders as compared with 2015 DRIs. The AMDR for protein was set at 7%–20% of energy intake, which was the same as 2015 DRIs. Current, average protein intake by the Korean population is almost twice times the EAR, which suggests it might be better to increase the minimal margin for AMDR.However, it was not adjusted in this revision due to lack of evidence.

Polydeoxyribonucleotide (PDRN) is a DNA-derived drug with a molecular weight of 50 to 1,500 kDa that is extracted from the sperm of fish such as salmon, trout, and sturgeon. PDRN activates the adenosine A2 receptor and salvage pathway, promoting bone cell activity, collagen synthesis, and angiogenesis. Numerous preclinical and clinical studies have described the wound healing and anti-inflammatory effects of PDRN. PDRN enhances tendon-to-bone healing in rotator cuff injuries, reduces fat degeneration, and has positive clinical effects on pain relief and functional recovery. In vivo studies on Achilles tendon injuries have shown that PDRN promotes collagen synthesis, inhibits cell apoptosis, and reduces inflammatory responses. In lateral epicondylitis of the elbow, PDRN administration improves pain and increases the thickness of tendons. PDRN has been reported to alleviate pain in plantar fasciitis. Moreover, PDRN promotes re-epithelialization in wound healing, diabetic ulcers, and pressure ulcers, leading to shortened healing periods and positive outcomes. In degenerative arthritis, PDRN administration has comparable or even superior effects to hyaluronic acid treatment. Numerous preclinical and clinical studies show that PDRN is a promising therapeutic approach for musculoskeletal disorders and skin healing, serving as an effective tissue regeneration stimulant.
