Background: Increased frequency of comminuted clavicle mid-shaft fractures and importance of functional satisfaction through early joint exercise has resulted in higher emphasis on surgical treatments. This study aimed to evaluate the clinical radiological results of treatment of clavicle mid-shaft fractures by open reduction and internal fixation using a plate with a small incision. Methods: The subjects of this study were 80 clavicle mid-shaft fracture cases treated with internal fixation using a plate from October 2010 to July 2014. Clavicle mid-shaft fractures were internally fixated using anatomical plates or locking compression plates. Achievement of bone union, union period, and clavicle length shortening were evaluated radiologically, and clinical assessment was done by using Constant and University of California at Los Angeles (UCLA) scores. Results: All 80 cases were confirmed to have achieved bone union through radiographs with an average union period of 10.9 weeks (range: 7-18 weeks). The average clavicle length of shortening in the affected side was 1.8 mm (range: 0-17 mm). The average UCLA score and Constant score were 33.6 (range: 25-35) and 92.5 (range: 65-100), respectively. Regarding complications, four cases reported skin irritation by metal plates, and one case reported a screw insertion site fracture due to minor trauma history. Conclusions: We were able to induce successful bone union and obtain clinically satisfactory results in displaced mid-shaft fractures of the clavicle without major complications such as nonunion through treatment of internal fixation using a plate.

Purpose: The causes of twelve cases of the mid-shaft clavicle nonunion and the results of internal fixation with plate and bone graft were investigated. Materials and method: From August 1997 to March 2003, twelve cases of the mid-shaft clavicle nonunion were operated with internal fixation with plate and bone graft. The duration of follow-up was average 13 months. Results: The causes of the mid-shaft clavicle nonunion included severe associated injury, severe initial displacement of the fracture fragments and insecure fixation. All cases were operated with internal fixation with plate and bone graft. According to the factor for evaluations of results, using a rating scale of excellent (no apparent factors), good (one factor), fair (two factors), poor (more than three factors), the results showed 10 excellent, 1 good and 1 poor. Screw loosening was developed in only one case . Conclusion: The internal fixation with plate and bone graft of the mid-shaft clavicle nonunion after failed conservative treatment achieved excellent results and seemed to be the procedure of choice for mid-shaft clavicle nonunion.

Purpose: Many different operative technique of mid-shaft clavicle fracture have been reported. The aim of this prospective study was to compare the results of anterior or anterior-inferior plating with superior plating on the acute mid-shaft fracture of clavicle Materials and Methods: From February1997 to February 2002, thirty-eight consecutive open reduction and internal fixation with reconstruction plates were performed in thirty-eight patients. from August 1999, anterior or anterior-inferior plating was mainly used, prospectively. The duration of follow-up averaged 17 months (range,23 to 43 months). The mean age was 38 years old (range,21 to 57 years old) on anterior or anterior-inferior plating group and 35 years old (range,24 to 55 years old) on superior plating group. The physician progress note, VAS patient complement score, Roentgenogram and ASES score was evaluated. Results: Four patients were lost to follow-up. There was no statistical difference on mean radiological bone union time （8.7 weeks vs. 8.6 weeks) and ASES score (92 vs 94) at inferior and superior plating groups (P > 0.05). VAS patient complement score was very good or excellent on anterior or anterior-inferior group, average score was 1.1 (ranger,0 to 2) compare with superior plating group (P < 0.05). There were two cases of infection, 1 case of failed fixation on superior plating group and 1 case of delayed union on anterior inferior plating group. Conclusion: Anterior inferior plating on acute clavicle midshaft fracture results in excellent patient complement score compare with conventional superior reconstruction plate.

Background: Recent studies about completely displaced midshaft clavicle fractures have reported that their nonunion/malunion rates were significantly higher in conservatively treated patients compared to surgically treated patients. The purpose of this study was to evaluate the factors associated with treatment decisions for midshaft clavicle fractures and also the factors that affect patient satisfaction with their treatment choice. Methods: We retrospectively reviewed the records of 75 patients who had been diagnosed with a midshaft clavicle fracture and were treated conservatively at a single institution between March 1, 2013, and December 31, 2014. Their medical records were reviewed to investigate the severity of the initial vertical displacement. A telephone survey was carried out to identify the presence of any patient-perceived deformity and determine if the patient eventually underwent surgery and whether the patient would prefer surgery if the injury recurred. Results: Significantly more patients with vertical displacement ≥100% (9/28) eventually underwent surgery compared to patients with vertical displacement <100% (3/32, p=0.028). Patients with vertical displacement ≥100% (13/28) were significantly more likely to prefer surgery compared to patients with vertical displacement <100% (7/32, p=0.044). Among the conservatively treated patients, nine of 32 participants with a patient-perceived deformity and one of 16 without a patient-perceived deformity responded that they would prefer to receive surgery in same situation in the future (p=0.079). Conclusions: Patients with a midshaft clavicle fracture with vertical displacement of ≥100% may eventually require surgical treatment. When conservative treatment is carried out, the long-term patient results may be unsatisfactory due to perceived residual deformities.

Background: A precontoured plate rarely fits properly within the patient's clavicle and must be bent intraoperatively. This study aimed to determine whether anatomical reduction could be achieved using a plate bent before surgery. Methods: This study included 87 consecutive patients with displaced mid-shaft clavicle fractures who underwent plate fixation and were followed-up for a minimum of 1 year. After exclusions, 39 consecutive patients underwent fixation with a precontoured plate bent intraoperatively (intraoperative bending group), and 28 underwent fixation with the plate bent preoperatively (preoperative bending group). Using free software and a three-dimensional (3D) printer, ipsilateral clavicle 3D-printed models were constructed. Using plain radiographs, the distance between the edge of the lateral inferior cortex and the medial inferior cortex was measured. The angle between the line connecting the inferior cortex edge and the line passing through the flat portion of the superior cortex of the distal clavicle was measured. Results: Mean length differences between the ipsilateral and contralateral clavicle were smaller on both anteroposterior (AP; P=0.032) and axial images (P=0.029) in the preoperative bending group. The mean angular differences on both AP (P=0.045) and axial images (P=0.008) were smaller in the preoperative bending group. No significant differences were observed between the two groups in functional scores at the last follow-up. Conclusions: Smaller differences in length and angle between the ipsilateral and contralateral clavicle, indicative of reduction, were observed in the preoperative bending group. Using the precontoured technique with low expense, the operation was performed more effectively as reflected by a shorter operation time. Level of evidence: III.

목적: 기존의 연구들은 쇄골의 부정 유합 및 불유합에 대한 지연 재건술의 결과가 골절 후 조기 수술적 치료에 필적할 만한 우수한 결과들을 보고하여 왔으나 두 군을 직접적으로 비교한 연구는 드문 실정이다. 저자들은 쇄골 불유합과 부정 유합의 지연 재건술 군과 조기 고정술 군 간의 결과를 비교하였다. 대상 및 방법: 2000년 3월부터 2006년 2월까지 전위성 쇄골 간부 골절에 대해 조기 고정술을 시행한 18예(조기 고정술 군)와 보존적 치료 후 발생한 부정 유합 혹은 불유합에 대해 지연 재건술을 시행한 15예(지연 재건술 군)를 대상으로 하였다. 최종 결과 판정은 Constant 점수에 의한 임상적 결과와 방사선학적 골유합 소견을 비교하였다. 결과: Constant 점수는 지연 재건술 군이 조기 고정술 군에 비해 의미있게 낮았다(p=0.045). 통증 점수와 일상 생활 활동 점수는 두 군간 통계학적으로 유의한 차이를 보였으나(p<0.05) 관절 운동 범위 점수와 근력 점수는 두 군간 통계학적 유의성을 보이지 않았다(p>0.05). 방사선학적 골유합 소견은 조기 고정술 군 평균 8.8주, 지연 재건술 군 평균 9.8주에 관찰되었고 두 군 모두 전례에서 골유합 소견을 보였다. 결론: 지연 재건술 군 또한 임상적, 방사선학적으로 우수한 결과를 보였지만 조기 고정술 군에 비해 Constant 점수와 통증 점수, 일상 생활 활동 점수에서 유의하게 낮은 결과를 보였다. 쇄골 전위성 간부 골절의 초기 치료 선택에 있어 조기 수술과 지연 재건술의 장단점을 환자에게 충분히 설명하고 초기 치료를 결정하는 것이 중요하리라 생각된다.

Background: Surgical-site, multimodal drug injection has recently evolved to be a safe and useful method for multimodal pain management even in patients with musculoskeletal trauma. Methods: Fifty consecutive patients who underwent plating for mid-shaft and distal clavicular fractures were included in the study. To evaluate whether surgical-site injections (SIs) have pain management benefits, the patients were divided into two groups (SI and no-SI groups). The injection was administered between the deep and superficial tissues prior to wound closure. The mixture of anesthetics consisted of epinephrine hydrochloride (HCL), morphine sulfate, ropivacaine HCL, and normal saline. The visual analogue scale (VAS) pain scores were measured at 6-hour intervals until postoperative hour (POH) 72; stress biomarkers (dehydroepiandrosterone sulfate [DHEA-S], insulin, and fibrinogen) were measured preoperatively and at POH 24, 48, and 72. In patients who wanted further pain control or had a VAS pain score of 7 points until POH 72, 75 mg of intravenous tramadol was administered, and the intravenous tramadol requirements were also recorded. Other medications were not used for pain management. Results: The SI group showed significantly lower VAS pain scores until POH 24, except for POH 18. Tramadol requirement was significantly lower in the SI group until POH 24, except for POH 12 and 18. The mean DHEA-S level significantly decreased in the no-SI group ($74.2{\pm}47.0{\mu}g/dL$) at POH 72 compared to that in the SI group ($110.1{\pm}87.1{\mu}g/dL$; p = 0.046). There was no significant difference in the insulin and fibrinogen levels between the groups. The correlation values between all the biomarkers and VAS pain scores were not significantly different between the two groups (p > 0.05). Conclusions: After internal fixation of the clavicular fracture, the surgical-site, multimodal drug injection effectively relieved pain on the day of the surgery without any complications. Therefore, we believe that SI is a safe and effective method for pain management after internal fixation of a clavicular fracture.
