Background: We analyzed association between viewing two-dimensional computed tomography (2D CT) images in addition to radiographs with radial head treatment recommendations after accounting for patient and surgeon factors in a survey-based experiment. Methods: One hundred and fifty-four surgeons reviewed 15 patient scenarios with terrible triad fracture dislocations of the elbow. Surgeons were randomized to view either radiographs only or radiographs and 2D CT images. The scenarios randomized patient age, hand dominance, and occupation. For each scenario, surgeons were asked if they would recommend fixation or arthroplasty of the radial head. Multi-level logistic regression analysis identified variables associated with radial head treatment recommendations. Results: Reviewing 2D CT images in addition to radiographs had no statistical association with treatment recommendations. A higher likelihood of recommending prosthetic arthroplasty was associated with older patient age, patient occupation not requiring manual labor, surgeon practice location in the United States, practicing for five years or less, and the subspecialties "trauma" and "shoulder and elbow." Conclusions: The results of this study suggest that in terrible triad injuries, the imaging appearance of radial head fractures has no measurable influence on treatment recommendations. Personal surgeon factors and patient demographic characteristics may have a larger role in surgical decision making. Level of evidence: Level III, therapeutic case-control study.

The terrible triad of the shoulder, a combination of anterior shoulder dislocation, massive rotator cuff tear and neurologic injury, is rare. We experienced 4 patients with this condition who were treated with a rotator cuff repair. The mean age was 65 years. Follow-up averaged 27 months. All patients had a history of redislocation after initial traumatic shoulder dislocation and were evaluated with electromyography and magnetic resonance imaging. At the operation, massive rotator cuff tear and hypertrophy of the long head of the biceps were found in all patients. Clinically, 3 patients achieved recovery of their nerve injury by 3 months postoperatively and the final results were fair. In one patient, there was no recovery of deltoid function and this case was rated as a failure. For this injury pattern, the prognosis appears to be dependent on eventual nerve recovery when the rotator cuff has been repaired early.

Background: Resection of the radial head is a surgical indication for comminuted radial head fracture in which internal fixation is inaccessible. Some complications from the surgery can alter the function of the patient's elbow. The objective of this study was to assess functional outcome of the elbow after resection of the radial head. Methods: A retrospective longitudinal study was performed with patients who underwent radial head resection between 2008 and 2018. Elbow function was assessed by the Mayo Elbow Performance Index (MEPI) for 11 patients comprising three women and eight men. The mean follow-up was 47.6 months. The mean age was 41±10.3 years. Results: Nine patients had a stable and painless elbow. The mean extension-flexion arc was 97.73°±16.03°. The mean values of pronation and supination were 76.8° and 74.5°, respectively. The mean MEPI score was 83.2 points, and restoration of overall function was achieved in 81% of the cases. Poor function was noted in one in 10 that presented with a terrible triad. Conclusions: Resection of the radial head restored elbow functionality at a rate of 81%, which was a good outcome for patients.

목적: 압박 긴장대 방법을 이용한 작은 구상 돌기 골절의 견고한 고정과 주관절의 조기 운동을 통한 기능의 향상 및 그 결과를 분석하고자 한다. 재료 및 방법: 주관절 내측접근법으로 K-강선과 철선을 이용하여 고정된 8예의 구상돌기 골절을 대상으로 하였다. 분류상 8예 모두 Regan-Morrey type 2였으며 O'Driscoll 분류12)로는 tip형(subtype 2)가 예, anteromedial 형 (subtype 2, 1예 그리고 subtype 3, 2예)3예였다. 동반 손상으로는 측부인대 파열이 6예, 요골두 및 경부골절이 4예였으며 모두 함께 치료하였다. 술 후 5~7일간의 고정 치료 후 경첩 보조기 (hinge brace)을 착용한 상태에서 술후 6주까지 능동적 운동을 허용하였다. 술 후 통증의 여부, 관절 운동 범위, Mayo elbow performance score(MEPS)을 이용한 기능적 평가 방법을 이용하여 치료 결과를 분석하였다. 평균 11 (6~28)개월 추시 하였으며 척골 신경 증상에 대해서도 함께 조사하였다. 결과: 모든 구상돌기 골절은 내고정용 도구의 실패 없이 모두 유합되었다. 평균 2.2 (2~4)개의 K-강선이 사용되었다. 관절운동 범위에 대해 신전은 평균 $3^{\circ}(0^{\circ}\sim25^{\circ})$, 굴곡는 평균 $137^{\circ}(130^{\circ}\sim140^{\circ})$, 회내전은 평균 $69^{\circ}(45^{\circ}\sim90^{\circ})$, 회외전은 $78^{\circ}(45^{\circ}\sim90^{\circ})$이였다. MEPS는 평균 96 (65~100) 이였다. 척골 신경 증상은 terrible triad 1예에서 첫 수술 (index operation)후 요골두를 절제하고 내측 측부 인대의 기능 부전이 있는 1예에서 관찰되었다. 결론: 쉽게 구할 수 있으며 가격이 저렴한 K-강선과 철선을 이용한 압박 긴장대 방법은 충분히 견고하여 조기에 능동적 운동을 허용할 수 있어 주관절의 기능 향상을 가져올 수 있었다. 이 방법은 특히 다발성 소형 구상 돌기 골절의 경우 유용한 하나의 고정 방법으로 생각된다.

Purpose: The nonoperative outcome of elbow dislocations with associated radial head and coronoid fractures are often unsatisfactory because of chronic instability and stiffness from proloned immobilization, Therefore we managed these injuries with well programed surgical appproaches. Method: Ten patients with this injury were evaluated retrospectively from May 1998 to June 2004 after a minimum of 12 months. These injuries include elbow dislocation and associated fractures of both the radial head and the coronoid process. All ten patients were treated by one clinic operatively with similar scheduled surgical methods which started on the lateral side and terminated on the medial side of the elbow. Radial head and neck fractures were classified Mason types, as two and three types respectively with six and four cases and six cases were fixated. Coronoid process were fixated with screws anteroposterior directly or anchor suture in all cases, each type was classified one, two and three. where were three type one, four type two, and three type three were according to Regan and Morrey classification. Results: The outcome was three resulting in excellent, four good, two normaland and the remaining case was one poor according to the Mayo Elbow Performance score. At a terminal follow up, the range of motion of the elbow averaged flection contracture, $6^{\circ}(0{\sim}20^{\circ})$ and further flection, $129^{\circ}(115{\sim}140^{\circ})$. Two patients had complications requiring additional care. One, displaced coronoid process which was repaired with capsule and the other patient experienced, palsy of ulnar nerve and contracted elbow joint. Conclusions: Usage of early operation as the minimum injury of medial ligaments complex and the rigid fixation of fractures to prompt motion with our scheduled management for elbow dislocations with associated radial head and coracoid fractures provided excellent results.
