대상포진에 의한 상완 신경총염은 매우 드문 질환이며, 일측 상지의 악화되는 통증, 근력 약화 및 늦은 회복을 특징으로 한다. 본 증례는 대상포진 바이러스에 의한 상완신경총염을 진단받은 54세 여자 환자가 이른 치료 시기에 통증 자극과 혈관수축 및 신경반흔 형성을 억제할 수 있는 성상신경절 차단술을 통해 빠른 회복을 보인 경우이다. Varicella zoster virus (VZV)-induced brachioplexitis is a rare disease, characterized by exacerbating ipsilateral upper extremity pain, muscular weakness, and delay in recovery. We report a 54-year-old female patient who made an early recovery from VZV-induced brachioplexitis via the treatment with stellate ganglion blocks, which may have prevented pain sensation, vasoconstriction, and nerve scarring during the early treatment period.

플라즈마 디스플레이 패널(Plasma Display Panel, PDP)의 구동은 리셋, 어드레싱 및 써스테인 구동으로 나뉘어진다. 써스테인 기간동안 원하는 영상을 표현하기 위해서는 어드레싱이 필요하며, 효과적인 어드레싱을 위해서는 리셋이 필수적으로 요구된다. 그러나 이 리셋은 적지 않은 시간을 필요로 하며 배경광을 발생시켜 명암비를 저하시키는 영향을 가져온다. 본 논문에서는 배경광의 발생을 최소화하며 효과적인 어드레싱을 위한 초기화를 효과적으로 달성하고 이 초기화에 소요되는 시간이 기존의 리셋 방식에 비하여 절반 정도인 새로운 리셋 구동 방식을 제시한다.

목적: 수근부 결절종의 개방절제술 후 잔존통증과 술 전 수근관절의 불안정성 및 전신이완의 연관성을 확인하기 위해 연구를 시행하였다. 대상 및 방법: 본 후향적 연구는 수근부 결절종으로 개방절제술을 시행한 64명을 대상으로 수술 후 잔존통증 및 기능과 술 전 수근부 불안정성 및 전신이완의 연관성을 확인하였다. 수근부 불안정성은 수부의 단순 방사선 검사(후방 개재 분절 불안정성[dorsal intercalated segment instability], 전방 개재 분절 불안정성[volar intercalated segment instability])와 신체검사(Watson scaphoid shift test)를 통하여 확인하였으며, 전신이완은 Beighton 과운동성 지표를 통해 평가하였다. 단순 방사선 검사 및 신체검사에서 동시에 양성 소견인 경우에 한해 수근부 불안정증이 있는 것으로 정의하였다. 결과: 수술 전에 비해 수술 후 시각 통증 점수와 quick disabilities of the arm, shoulder and hand (quick-DASH)는 유의하게 호전되었다. 수술 후 잔존통증은 수근부 불안정증이 있는 경우(n=6)가 2.50±1.76점, 없는 경우(n=58)가 1.18±1.24점으로 유의한 차이가 있었다(p=0.022). 술 후 quick-DASH의 경우 술 전 수근부 불안정증에 따른 유의한 차이를 보이지 않았다. 전신이완증(n=18)은 잔존통증 및 quick-DASH와 연관성이 없었다. 결론: 수근부 결절종의 개방적 절제술에서 수술 후 잔존통증 점수는 수술 전 수근부 불안정증이 있었던 군에서 없었던 군보다 높았으며, 전신이완증과는 연관관계가 없었다. Purpose: The purpose of this study was to verify the relationship between the residual pain and preoperative carpal instability, as well as the generalized laxity after open excision of wrist ganglion. Materials and Methods: Sixty-four patients, who received open excision of wrist ganglion, were retrospectively enrolled. The relationships between residual pain (visual analogue scale, VAS) and postoperative function (quick disabilities of the arm, shoulder and hand, quick-DASH), between residual pain and preoperative carpal instability, as well as generalized laxity were evaluated. The carpal instability was assessed from radiologic carpal instability (dorsal intercalated segment instability and volar intercalated segment instability) and Watson scaphoid shift test. The generalized laxity was assessed by the Beighton hypermobility score. Results: Pain VAS and quick-DASH were significantly improved postoperatively. There was a significant difference in postoperative residual pain between those with (n=6) and without carpal instability (n=58) (+: 2.50±1.76 vs. -: 1.18±1.24; p=0.022), but there was no correlation between carpal instability and postoperative quick-DASH. Both postoperative residual pain and quick-DASH had no correlation with generalized laxity (n=18). Conclusion: Patients with preoperative carpal instability had greater residual pain after excision of wrist ganglion than those without.

The aim of this survey was to analyze the characteristics of musculoskeletal pain of Korean junior tennis players and its effect on games and psychology of players. Surveys were administered to 30 healthy male junior tennis players who took part in a 50th national junior tennis meet in 2015. We analyzed the incidence, location, cause and preferred prevention or treatment method of musculoskeletal pain, the correlation between training time and musculoskeletal pain as well as the effect of musculoskeletal pain on games and psychology of players. Overall, 22 out of 30 (73.3%) responded the experience of musculoskeletal pain. The incidence of lower extremity pain (16 out of 30, 53.3%) were higher than upper extremity pain (9 out of 30, 30%) and low back pain (8 out of 30, 26.7%). The long training hours per day (r=0.574, p=0.001) and old age (r=0.390, p=0.033) were correlated with intermittent back pain in univariate anlaysis. In multivariate ananlysis, the long training hours per day was a single risk factor of intermittent low back pain (p=0.038, odds ratio 10.01). 43.3% of players responded that the insufficent preventive conditioning program was thought to be the cause of musculoskeletal pain. The most preferred treatment or prevention method for musculoskeletal pain was rehabilitation (55.3%). Twelve players reported the negative affection of musculoskeletal pain to the performance in game. Six players experienced the frustration, 9 playersexperienced the loss of interest and 9 players experienced the emotional avoidance of games due to the musculoskeletal pain.

Purpose: The aim of current study is to verify the efficacy of extracorporeal shock wave therapy (ESWT) in neck and shoulder pain syndrome. Methods: We enrolled 23 patients with neck and shoulder pain syndrome (mean age, 55±16 years; onset, 12.65±8.90 months) who underwent ESWT from July to December 2019. ESWT (4 to 5 bar or 0.23-0.45 mJ/mm<sup>2</sup>, 1,500 to 2,000 times/region, 7 Hz) was performed at least 4 consecutive times per week. Evaluated outcomes were visual analogue scale (VAS) of pain and tenderness, neck disability index (NDI), and shoulder passive range of motion (ROM; forward flexion [FF], external rotation at neutral [ER], internal rotation at back [IR]). Pain and tenderness VAS scores were assessed at every follow-up, while NDI and shoulder ROM were evaluated two times before treatment and at the final follw-up (at 4.52±0.73 weeks). Results: The pain VAS score decreased from 5.5±2.4 at first visit to 4.0±1.8 (p=0.001), 3.3±2.1 (p=0.02), and 3.1±2.2 (p=0.29) at the first, second, and third follow-up visits. The tenderness VAS at first visit was 5.98±1.89, which decreased to 5.17±1.83 (p=0.005), 4.61±1.67 (p=0.05), and 4.09±1.92 (p=0.06) at the first, second, and third follow-up visits. NDI was significantly reduced from 18.04±8.86 to 10.04±6.94 at last follow-up (p=0.001) and shoulder ROM was significantly improved after treatment (FF: 159.6°±28.0° to 177.8°±8.5°, p=0.001; ER: 72.2±15.7° to 79.6±2.1°, p=0.02; IR: 10.2±3.49 [T 10] to 6.9±1.7 [T 7], p=0.001). Conclusion: Consecutive ESWT was effective in treating neck and shoulder pain syndrome with functional improvement and pain reduction. Regarding simultaneous pain and tenderness reduction, receiving ESWT two times per week was effective.

견봉쇄골 관절 낭종은 광범위 회전근개 파열, 가성 종양, 견관절 감염, 연골 석회증과 관련되어 소수만 보고 되고 있다. 저자들은 관절경적 회전근개 봉합술 후 재파열과 동반된 견봉 쇄골 관절 낭종의 증례를 경험하였으며, 환자가 회전근개파열 수술 후 견봉쇄골 관절의 돌출이나 종괴를 보일 때 임상의들은 회전근 개 치유 여부에 대한 추시 영상 검사를 고려해야 할 것으로 사료된다. 특히, 초음파 검사는 사용 간편성과 경제적 측면에서 우수하며, 접근성이 용이하다는 점에서 이런 추시 영상 검사에 추천된다. Acromio-clavicular (AC) joint cyst have been reported in small series of the orthopedics literature in association with extensive rotator cuff tear, pseudotumor, infection of the shoulder or chondrocalcinosis. Authors experienced one case of AC joint cyst with rotator cuff re-tear after arthroscopic rotator cuff repair, clinicians may need pay attention to AC joint bulging or mass lesion after arthroscopic rotator cuff repair as an important sign to check follow-up imaging study for the cuff integrity. Especially, ultrasonography is recommended for this follow up study, because it is simple to be operated, economic, easily accessible.
