Abstract：
UNASSIGNED: To analyze the effectiveness of binocular loupe assisted mini-lateral and medial incisions in lateral position for the release of elbow stiffness.
UNASSIGNED: The clinical data of 16 patients with elbow stiffness treated with binocular loupe assisted mini-internal and external incisions in lateral position release between January 2021 and December 2022 were retrospectively analyzed. There were 9 males and 7 females, aged from 19 to 57 years, with a median age of 33.5 years. Etiologies included olecranon fracture in 6 cases, elbow dislocation in 4 cases, medial epicondyle fracture in 2 cases, radial head fracture in 4 cases, terrible triad of elbow joint in 2 cases, supracondylar fracture of humerus in 1 case, coronoid process fracture of ulna in 1 case, and humerus fracture in 1 case, with 5 cases presenting a combination of two etiologies. The duration of symptoms ranged from 5 to 60 months, with a median of 8 months. Preoperatively, 12 cases had concomitant ulnar nerve numbness, and 6 cases exhibited ectopic ossification. The preoperative range of motion for elbow flexion and extension was (58.63±22.30)°, the visual analogue scale (VAS) score was 4.3±1.6, and the Mayo score was 71.9±7.5. Incision lengths for both lateral and medial approaches were recorded, as well as the occurrence of complications. Clinical outcomes were evaluated using Mayo scores, VAS scores, and elbow range of motion both preoperatively and postoperatively.
UNASSIGNED: The lateral incision lengths for all patients ranged from 3.0 to 4.8 cm, with an average of 4.1 cm. The medial incision lengths ranged from 2.4 to 4.2 cm, with an average of 3.0 cm. The follow-up duration ranged from 6 to 19 months and a mean of 9.2 months. At last follow-up, 1 patient reported moderate elbow joint pain, and 3 cases exhibited residual mild ulnar nerve numbness. The other patients had no complications such as new heterotopic ossification and ulnar nerve paralysis, which hindered the movement of elbow joint. At last follow-up, the elbow range of motion was (130.44±9.75)°, the VAS score was 1.1±1.0, and the Mayo score was 99.1±3.8, which significantly improved when compared to the preoperative ones ( t=-12.418, P<0.001; t=6.419, P<0.001; t=-13.330, P<0.001).
UNASSIGNED: The binocular loupe assisted mini-lateral and medial incisions in lateral position integrated the advantages of traditional open and arthroscopic technique, which demonstrated satisfying safety and effectivity for the release of elbow contracture, but it is not indicated for patients with posterior medial heterolateral heterotopic ossification.
UNASSIGNED: 探讨侧卧位放大镜辅助下内外侧小切口手术松解肘关节僵硬的疗效。.
UNASSIGNED: 回顾分析2021年1月—2022年12月采用侧卧位放大镜辅助下内外侧小切口松解手术治疗的16例肘关节僵硬患者临床资料。其中男9例，女7例；年龄19～57岁，中位年龄33.5岁。病因：尺骨鹰嘴骨折6例，肘关节脱位4例，内上髁骨折2例，桡骨头骨折4例，肘关节恐怖三联征2例，肱骨髁上骨折1例，尺骨冠突骨折1例，肱骨骨折1例；其中5例患者合并2种病因。病程5～60个月，中位病程8个月。术前合并尺神经麻木症状12例，异位骨化6例。术前肘关节屈伸活动度为（58.63±22.30）°，疼痛视觉模拟评分（VAS）为（4.3±1.6）分，Mayo评分为（71.9±7.5）分。记录患者内、外侧切口长度；记录并发症发生情况，并采用手术前后患侧肘关节Mayo评分、VAS评分、肘关节屈伸活动度评价临床疗效。.
UNASSIGNED: 患者外侧切口长度为3.0～4.8 cm，平均4.1 cm；内侧切口长度为2.4～4.2 cm，平均3.0 cm。16例均获随访，随访时间6～19个月，平均9.2个月。末次随访时，1例患者存留轻微肘关节疼痛，3例残存轻微尺神经麻木症状。其余患者未发生影响肘关节活动的新发异位骨化、尺神经麻木等并发症。末次随访时，患者肘关节屈伸活动度为（130.44±9.75）°，VAS评分为（1.1±1.0）分，Mayo评分为（99.1±3.8）分，均较术前显著改善，差异有统计学意义（ t=−12.418， P<0.001； t=6.419， P<0.001； t=−13.330， P<0.001）。.
UNASSIGNED: 侧卧位放大镜辅助下内外侧小切口松解技术融合了传统开放技术和关节镜技术的优点，可微创、安全、有效地对肘关节僵硬患者完成松解手术，但该技术不适合严重异位骨化以及存在关节内畸形、游离体或骨赘的患者。.
