  • Total elbow prostheses which are now available in clinical use can generally be classified into two major categories ; one bing linked prostheses, another being unlinked prostheses. Of those two categories I am dealing here only with the problems of the unlinked type prosthesis, particularly with those of non-constrained, surface-replacement prostheses. Furthermore, my presentations this time may have to be narrowed down only to the topics regrading the particular features and some of the technical problems with Kudo Elbow Prosthesis, due to the time limit assigned for this presentation.

  • Purpose: To evaluate the results in patients who received total elbow replacement for posttraumatic destroyed or unreduced elbow joint. Materials and Methods: Six patients with posttraumatic destroyed, or unreduced elbow joint, who were nearly impossible to move actively and had pain and grossly unstable joint, were followed up average 42 months. 3 cases were soft tissue injuries and bone defects which were caused by severe comminuted fracture, 1 was a nonunion with comminuted fracture, and 2 were unreduced elbow joint. Total elbow replacement was performed average 10 months after the injury. All the cases were used by semiconstrained prosthesis, and the results were estimated by Mayo elbow perfomance score. Results: Pain was decreased in all the cases postoperatively. Average ranges of motion were improved with active extension 20° and flexion 120°. Mayo elbow performance scores were pain 42.5 points, range of motion 17.5 points, stability 8.3 points, function 19.2 points and totally 87.5 points, and final results were 3 excellent and 3 good. Loosening of prosthesis was not found in all the cases by final follow-up radiograph. Conclusicon: Semiconstrained TER can be used as a effective treatment improving pain and active ranges of motion caused by posttraumatic destroyed or unreduced elbow joint, however, long term follow-up is needed because early loosening of TER can be occurred due to severe bone defects.

  • Indications of reverse total shoulder arthroplasty (RTSA) have been consistently extended by technical advancements in reverse arthroplasty prosthesis, continuous development of the implants, accumulated experiences and its successful treatment outcomes; accordingly, its use has rapidly increased. RTSA has been performed for a variety of indications, with variable outcomes depending on the initial diagnosis. However, controversial opinions still exist regarding the design of reverse arthroplasty prosthesis (medialized or lateralized design and the neck-shaft angle of the humeral prosthesis), suture of the subscapularis tendon, use of cement during placement of the humeral prosthesis, and surgical procedures; therefore, these should be investigated so that they can be better understood.

  • Background: Posterolateral rotatory instability (PLRI) is a common mechanism of recurrent elbow instability. While the essential lesion is a deficiency in the lateral ulnar collateral ligament (LUCL), there are often associated concomitant bony lesions, such as an Osborne-Cotterill lesions (posterior capitellar fractures) and marginal radial head fractures, that compromise stability. Currently, there is no standard treatment for posterior capitellar deficiency associated with recurrent PLRI. Methods: We conducted a retrospective review of five patients with recurrent PLRI of the elbow associated with a posterior capitellar impaction fracture engaging with the radial head during normal range of motion. The patients were treated surgically with LUCL reconstruction or repair and off-label reconstruction of the capitellar joint surface using a small metal prosthesis designed for metatarsal head resurfacing (HemiCAP toe classic). Results: Five patients (three adolescent males, two adult females) were treated between 2007 and 2018. At a median follow-up of 5 years, all patients had complete relief of their symptomatic instability. No patients had pain at rest, but two patients had mild pain (visual analog scale 1-3) during physical activity. Three patients rated their elbow as normal, one as almost normal, and one as greatly improved. On short-term radiographic follow-up there were no signs of implant loosening. None of the patients needed reoperation. Conclusions: Recurrent PLRI of the elbow associated with an engaging posterior capitellar lesion can be treated successfully by LUCL reconstruction and repair and filling of the capitellar defect with a metal prosthesis. This treatment option has excellent clinical results in the short-medium term. Level of evidence: IV.

  • Background: As the population is aging and indications are expanding, shoulder arthroplasty is becoming more frequent, especially bilateral staged replacement. However, surgeons are hesitant to use bilateral reverse prostheses due to potential limitations on activities of daily living. Methods: This meta-analysis was conducted to compare bilateral anatomic to bilateral reverse shoulder implants. PubMed, Cochrane, and Google Scholar (pages 1-20) were searched until April 2023. The clinical outcomes consisted of postoperative functional scores (American Shoulder and Elbow Surgeons [ASES], Single Assessment Numeric Evaluation [SANE], Physical Component Score [PCS], Mental Component Score, and Simple Shoulder Test), pain, and range of motion (external rotation and forward elevation). Three studies were included in this meta-analysis. Results: Bilateral anatomic implants had better postoperative functional outcomes and range of motion, but no significant difference was seen in postoperative pain when compared to the reverse prosthesis. Better ASES score, SANE score, and PCS as well as better external rotation and forward elevation were seen in the bilateral anatomic shoulder replacement group, but no significant difference in pain levels was seen between the two groups Conclusions: The results may be explained by the lower baseline seen in the reverse prosthesis group, which may be due to an older population and different indications. Nevertheless, more randomized controlled studies are needed to confirm these findings. Level of evidence: III.

  • 목적: 금속 요골두 치환술은 주관절 불안정성을 동반한 고정할 수 없는 분쇄된 요골두 골절의 치료로 최근 다양한 임플란트의 개발로 널리 사용되고 있다. 저자는 금속성 요골두 치환술의 적응증과 국내에 사용중인 임플란트의 종류와 수술 술기를 문헌 고찰과 함께 기술하고자 한다. 대상 및 방법: 요골두 치환술의 주 적응증은 동반된 연부조직 손상으로 인한 주관절의 불안정성이 있고, 요골두의 분쇄 골절로 안정적인 내고정이 불가능한 골절이다. 이러한 경우 과거 시행되었던 요골두 절제술은 많은 합병증의 발생으로 금기시되고 있다. 현재 국내에서는 양극성, 압박 고정 단극성 및 이완 고정 단극성 임플란트의 3종류가 수입되어 사용되고 있다. 요골두 치환술은 궁극적으로 원래의 요골두의 크기와 길이로 복원하는 것이 중요하다. 과도하게 긴 요골두의 삽입은 흔한 합병증으로 수술 시 주의가 필요하다. 결과 및 결론: 요골두 치환술은 적절한 적응증과 정확한 수술 술기로 만족할 만한 임상적 결과를 얻을 수 있다. 향후 장기추시 연구와 다양한 치환물들의 임상적인 비교 연구가 필요하다.

  • The purpose of this case study was to introduce a myoelectric hand prosthesis for upper extremity amputee and prosthetic training program. Limb loss can result from disease, injury, or congenital causes. Trauma has been increasingly important role as the cause of amputaion in young, vigorous, and otherwise healthy individuals. The higher the level of amputation the greater the functional loss of the part, and the more the amputee must depend on the prostheis for fuction and cosmesis. Myoelectrical control of prostheses is a recent development and has been steadily gaining in clinical use over the past 20 years. Such a prosthesis uses signals from muscle contraction within the stump to activate a battery driven moter that operates specific component fuctions of the prosthesis. This twenty years old male case was operated a right above-elbow amputation due to tracffic accident and admitted to Yonsei Rehabilitaion hospital for the preprosthetic and prosthetic training. The case was able to successfully complete his myoelectric hand prosthesis training in the February of 1995.
