Chinese term or phrase: 前中1/3
原文:ACCF术后螺钉的应力主要集中于螺钉的前中1/3。
原文的意思是将螺钉全长等分为3段,前段和中段相接的那个点即是文中的“前中1/3”,英语如何表达比较准确?

at the point one third of length down from the front of the screw
Explanation:
ACCF术后螺钉的应力主要集中于螺钉的前中1/3。
After ACCF treatment, the stress of the screw mainly concentrates at the point one third of length down from the front of the screw.

我不知 “前” 是指螺丝的 “头”(大的那边),还是螺丝的 “尖”。

如果是 “头”:
After ACCF treatment, the stress of the screw mainly concentrates at the point one third of length down from the head of the screw.

如果是 “尖”:
After ACCF treatment, the stress of the screw mainly concentrate at the point one third of length down from the tip of the screw.

Anterior_Cervical_Corpectomy_and_Fusion_ACCF BACKGROUND Anterior cervical plate and cage fixation system (ACPC) used in anterior cervical corpectomy and fusion (ACCF) is reported to incur excess complications. This study aimed to introduce integrated fixation cage (IFC) into ACCF to eliminate the anterior cervical plate (ACP)-related complications. MATERIAL AND METHODS One validated intact and 3 ACCF-simulated C3-C7 cervical spine models were developed. In ACCF models, C5 was corpectomied and fixed by IFC or ACPC. For each model, 1.0 Nm moments of flexion, extension, lateral bending, and torsion were imposed on the C3 vertebra. The range of motion (ROM) of each segment and the stress distribution on screw-vertebra interface, bone graft, and cage-endplate were recorded and analyzed. RESULTS ROMs of C3-C7 were not different in any motion condition between IFC and ACPC models. The maximal von Mises stress on screw-vertebra interface of the IFC model was lower than that of the ACPC models in flexion, extension, and lateral bending, but higher in rotation. The maximal von Mises stress on bone graft of the IFC model was higher compared with the ACPC models, except in flexion

semanticscholar.org page 6 Stress distribution on screw-vertebra interface
The screw-vertebra stress was associated with the type of fixation device but showed the opposite trend in different motion direction. Compared with the ACPC (0° screw) and ACPC
(45° screw) models, the max screw-vertebra stress of the IFC
model was lower in flexion (56%, 54%), extension (28%, 45%),
and lateral bending (20%, 11%), but higher in rotation (68%,
43%). The angular position of the screw altered the stress distribution on screw-vertebra, but not significantly: ACPC (45°
screw) models showed higher max stress in extension (30%)
and rotation (17%) and lower max stress in flexion (4%) and
lateral bending (10%). The stress was mainly concentrated on
the interface of screw and cortical bone in all models (Figure 5).
