외상은 횡문근육종을 포함한 일부 육종의 발생에 영향을 미친다고 알려져 있고 수술 후 반흔이나 화상 흉터, 골절 부위, 금속 내고정물 주위에서 수년 간의 잠복기를 거쳐 육종을 일으킨 사례들이 드물게 보고되고 있다. 저자들은 컨베이어 벨트에 의해 압궤상을 입은 전완부에 11년 뒤 발생한 횡문근육종의 사례를 경험하였다. 조직 손상으로 인한 염증 반응, 많은 방사선 촬영에 대한 노출, 금속 내고정물, 감각 및 운동 마비로 인한 무의식적이고 반복적인 손상이 육종의 발생에 영향을 미쳤으리라고 생각된다. 이러한 광범위한 조직 손상 후에는 육종 발생 가능성을 염두에 두고 육종 유발 요인에 대한 노출에 주의를 기울여야 하겠다.

골수강 내 금속정(골수정)은 1988년부터 대퇴골 전자간 골절을 치료하는 데 사용되어 왔다. 골수정은 활강고나사와 같은 골수강 외 고정 장치에 비하여 기계적 이점이 있으나 대퇴 전자간 골절 Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) 31-A1 및 31-A2 골절 치료에 활강고나사보다 유리한 고정 기구인지에 대해서는 논란이 계속되고 있다. 지난 30년 동안 여러 시행 착오가 극복되었고 새로운 유형의 대퇴 골수정이 개발되어 임상에서 사용되고 있다. 새로 개발된 골수정은 삽입 과정이 쉬워지고 지연나사를 사용한 대퇴 골두의 고정 능력이 향상되어 왔다. 그러나 고정 실패율은 여전히 정형외과 의사의 수술 술기에 달려 있다고 할 수 있다. 이 종설에서 우리는 골수정을 이용하여 대퇴 전자간 골절을 치료하는 동안 내측 지지대 복원의 중요성에 대해 초점을 맞추고 그 기본 원칙에 대하여 논의해 보고자 한다.

일반적으로 슬관절 탈구의 대부분은 단순 견인에 의하여 쉽게 정복된다. 매우 드물게 슬관절 탈구에서 도수정복을 시도하나 파열된 인대나 근육이 관절에 끼어 정복되지 않는 경우가 있다. 이러한 정복되지 않는 슬관절 탈구의 증례가 종종 보고되었으나 넙다리빗근(sartorius muscle)에 의한 포착으로 인한 경우는 문헌상 보고된 바가 없다. 저자들은 단순 견인으로 정복되지 않는 슬관절 후외측 회전 탈구를 비관혈적 도수정복으로 정복한 증례 1예를 경험하여 문헌 고찰과 함께 보고하고자 한다. 이 증례는 임상의가 도수정복으로 정복되지 않는 슬관절 탈구를 경험할 때 임상적으로 고려해야 할 사항들에 대해 짚어 보는 기회가 될 것으로 생각된다.

Purpose: Percutaneous iliosacral (IS) screw fixation for pelvic ring injuries is a minimally invasive technique that reduces the amount of blood loss and shortens the procedure time. Moreover, two unilateral IS S1 screws exhibit superior stability to a single IS screw and are also safer for neurological injuries than an S2 screw. Therefore, this study aimed to evaluate fixation using percutaneous two unilateral IS S1 screws for pelvic ring injuries and its subsequent clinical outcomes. Methods: We retrospectively reviewed 38 patients who underwent percutaneous two unilateral IS S1 screw fixation for pelvic ring injuries. The procedure time, blood loss, achievement of bone union, radiological outcomes (Matta and Tornetta grade), and postoperative complications were evaluated. Results: The mean procedure time, hemoglobin loss, bone union rate, and time to union were 40.1 minutes (range, 18-102 minutes), 0.6 g/dL (range, 0.3-1.0 g/dL), 100%, and 153.2 days (range, 61-327 days), respectively. The Matta and Tornetta grades were excellent, good, and fair in 24 (63.1%), 11 (28.9%), and three patients (7.9%), respectively, and the postoperative complications were S1 screw loosening, widening of the symphysis pubis (2.3 and 2.5 mm), lumbosacral plexopathy, and S1 radiculopathy in one (2.6%), two (5.3%), one (2.6%), and one patient (2.6%), respectively. However, all neurological complications recovered spontaneously. Conclusions: Percutaneous two unilateral IS S1 screw fixation was useful for treating pelvic ring injuries. In particular, it involved a short procedure time with little blood loss and also led to 100% bone union and good radiological outcomes.

Background: In patients with total elbow arthroplasty (TEA), the soft-tissue around the elbow can be vulnerable to soft-tissue complications. This study aims to assess the outcomes after soft-tissue reconstruction following TEA. Methods: We retrospectively included nine adult patients who underwent soft-tissue reconstruction following TEA. Demographic data and disease characteristics were collected through medical chart reviews. Additionally, we contacted all four patients that were alive at the time of the study by phone to assess any current elbow complications. Local tissue rearrangement was used for soft-tissue reconstruction in six patients, and a pedicle flap was used in three patients. The median follow-up period was 1.3 years (range, 6 months-14.7 years). Results: Seven patients (78%) underwent reoperation. Four patients (44%) had a reoperation for soft-tissue complications, including dehiscence or nonhealing of infected wounds. Five patients (56%) had a reoperation for implant-related complications, including three infections and two peri-prosthetic fractures. At the final follow-ups, six patients (67%) achieved successful wound healing and two patients had continued wound healing issues, while two patients had an antibiotic spacer in situ and one patient underwent an above-the-elbow amputation. Conclusions: This study reports a complication rate of 78% for soft-tissue reconstructions after TEA. Successful soft-tissue healing was achieved in 67% of patients, but at the cost of multiple surgeries. Early definitive soft-tissue reconstruction could prove to be preferable to minor interventions such as irrigation, debridement, and local tissue advancement, or smaller soft-tissue reconstructions using local tissue rearrangement or a pedicled flap at a later stage.

Background: The subacromial (SA) space is a commonly used injection site for treatment of impingement syndrome. For shoulder stiffness, glenohumeral (GH) injections are commonly performed. However, in cases of impingement syndrome with mild shoulder stiffness, the optimal site of steroid injection has yet to be identified. Methods: This prospective, randomized study compared the short-term outcomes of ultrasound-guided GH and SA steroid injections in patients who were diagnosed with impingement syndrome and mild stiffness. Each group comprised 24 patients who received either a GH or SA injection of 40 mg of triamcinolone. Range of motion and clinical scores were assessed before and 3, 7, and 13 weeks after the injection. Results: GH and SA injections significantly improved the range of motion and clinical scores after 13 weeks of follow-up. Notably, targeting the GH joint resulted in an earlier gain of forward elevation, external rotation, and internal rotation in 3 weeks (P<0.001, P=0.012, and P=0.002, respectively) and of internal rotation and a Constant-Murley score in 7 weeks (P<0.001 and P=0.046). Subsequent measurements were similar between the groups and showed a steady improvement in all ranges of motion and clinical scores. Conclusions: GH injections may be more favorable than SA injections for treatment of impingement syndrome with mild stiffness, especially in improving the range of motion in the early period. However, the procedures showed similar outcomes after 3 months. Level of evidence: I.

Achilles tendinopathy has seen good results with conservative management. However, the management of Achilles tendinopathy lacks evidence-based support, and tendinopathy patients are at risk of long-term morbidity with unpredictable clinical outcomes. Data suggests that 29% of tendinopathy patients required surgical intervention during the follow-up period. Chronic pain after damage to the Achilles tendon is a result of incomplete recovery of fibrous tissue. Recently, many procedures, including various injection treatments, have been tried without understanding proper preservation techniques and procedures for faster tendon recovery, especially for patients who want to quickly return to their daily lives. This article is an extensive literature review on nonoperative management of Achilles tendinopathy.

The intercostobrachial nerve (ICBN) originates from the second intercostal nerve's lateral cutaneous branch, while the median nerve (MN) typically arises from the brachial plexus's lateral and medial roots. The medial cutaneous nerve of the arm, a branch of the medial cord of the brachial plexus, often connects with the ICBN. Variations were observed during the dissection of a 50-year-old male cadaver, including MN having two lateral roots (LR), LR1 and LR2, joining at different levels. Three ICBNs innervated the arm in this case, with the absence of the medial cutaneous nerve of the arm compensated by branches from the medial cutaneous nerve of the forearm. Understanding these anatomical variations is crucial for surgical procedures like brachioplasty, breast augmentation, axillary lymph node dissection, and orthopedic surgery. Surgeons and medical professionals must be aware of these variations to enhance preoperative planning, minimize complications, and improve patient outcomes in these procedures.

Purpose: The purpose of this study is to evaluate the effect of axial shortening metatarsal osteotomy on the treatment of advanced rheumatoid arthritis patients with severe hallux valgus and claw toe deformity of lesser toes which is used for preserving the metatarsophalangeal joint. Materials and Methods: From January 2005 to June 2009, 18 cases of axial shortening metatarsal osteotomy in advanced rheumatoid arthritis were reviewed ; all of them followed up for more than 2 years after surgical procedures and the mean follow up period was 3.4 years. We performed axial shortening Scarf osteotomy and Akin osteotomy for hallux valgus and Weil osteotomy with soft tissue release for claw toe of lesser toes, respectively. We measured preoperative and postoperative hallux valgus angle, each metatarsal shortening length and the range of motion of the metatarsophalangeal joints through radiographic and clinical examination and compared them each other. Clinical results were evaluated by American Orthopedic Foot and Ankle Society (AOFAS) score and subjective satisfaction of the patients. Results: The hallux valgus angle was reduced from the preoperative mean value of 44.8 degree to 9.0 degree postoperatively and the range of motion of the metatarsophalangeal joint of great toe and lesser toes was increased from the mean of 21.7 degree and 11.0 degree preoperatively to 38.0 degree and 32.5 degree, respectively at postoperation. Also, the mean AOFAS score was improved from 26.5 points to 67.4 points. Conclusion: Axial shortening osteotomy is a useful method to correct the deformity and preserve the metatarsophalangeal joint for severe hallux valgus and claw toe deformity in advanced rheumatoid arthritis.

The PCL reconstruction in chronic isolate PCL reconstruction was still controversy. 1) In isolate PCL deficient knee, functionally not so bad as like ACL deficient knee. 2) The result of the PCL reconstruction was not as good as ACL reconstruction. Therefore, isolate PCL injuries has been treated as nonoperatively. Hey Grovere, who was the first to attempt an intra-articular reconstruction of the PCL, utilized the semi-tendinous tendon other static procedures have been described in only a few cases with very limited follow-up. Dynamic procedures utilizing the medial head of the gastrocnemius has been reported by Hugston and Degenhardt, Kennedy and Grainger, and Insall and Hood. These procedures did not improve static stability. Dr Clancy, who was introduce the use of BPTB for the PCL reconstruction transtibial and femoral tunnel. From 1995, untill early 1990 PCL reconstruction was done as tend as placement of the isometric point. Physiometic placement of Anatomical placement of the femoral tunnel in PCL reconstruction were introduced in 1995. Tibial Inlay Technique was reported by Dr Berg in 1995. The main advantage of the tibial Inlay Technique was to avoid fraying of the graft at the posterior tibial tunnel orifice. In complete PCL ruptured and severely posterior unstable knee, dual femoral tunnel technique will be to get better result than one bundle technique. To achieve restoration of normal posterior laxity, it is critical to address the posterior as well as the posterolateral structures. Futher research is necessary to evaluate new surgical approches such as double-bundle reconstructions and tibial inlay techniques as well as improved techniques for capsular and collateral ligament injuries.
