After operation, 1 case had loosening of fixation pin, 1 case had severe pain, 4 cases had joint stiffness, 1 case had malunion of fracture, 1 case had damage of articular surface and obviously narrow joint space, 4 cases had poor tolerance to cold stimulation. In the last follow-up, total active motion (TAM) was used to evaluate the function. The results were rated as excellent in 15 cases, good in 5 cases, fair in 7 cases and poor in 2 cases, with the excellent and good rate being 69%.

The space between abductor pollicis longus tendon and extensor pollicis brevis tendon was served as the first operative window. The fracture end and carpometacarpal joint of thumb were exposed. The periosteum was cut on the ulnar side of the extensor pollicis brevis tendon served as the second operative window. C-shaped pulley forceps was placed on the volar and ulnar side of the bone fragments. The bone fragments were hooked and controlled. The first metacarpal bone was pulled and pronated by an assistant. Under direct vision, anatomical reduction of bone fragments can be seen. Kirschner wire with a diameter of 1.0 or 1.2 mm was used to fix the fracture and carpometacarpal joint of thumb at the second and first operation windows respectively. After 4 weeks of plaster fixation, Kirschner wire was removed which was used for fixation of carpometacarpal joint of thumb and brace was used for fixation. The rehabilitation training of each joint of thumb was done intermittently. After 2 to 3 months, the remaining Kirschner wires were removed according to the fracture healing. \u0000 \u0000 \u0000Results \u0000After operation, all the wounds achieved primary healing.

The length of the distal radioulnar ligament was obtained by measuring the distance between the sigmoid notch and the base and recess of styloid process of ulna. \u0000 \u0000 \u0000Results \u0000On the radiocarpal joint surface, the fracture line was mainly concentrated around the lunate fossa demonstrated as cross; on the volar side, the fracture line was mainly concentrated around the watery flow line; on the dorsal side, the fracture line was concentrated around Lister's tubercle and scattered; in the area of sigmoid notch, the fracture line was concentrated in the middle 1/3 and dorsal 1/3 of sigmoid notch; in the area of styloid process of radius, it was seen that the styloid process of radius was relatively complete, and the fracture line was distributed under the styloid process of radius. There was no significant difference in the length of the four groups of ligaments, i.e. the volar superficial distal radioulnar ligament, the dorsal superficial distal radioulnar ligament, the volar deep distal radioulnar ligament and the dorsal deep distal radioulnar ligament among the subtypes (C1, C2, C3) of type C distal radius fracture (P>0.05); there was no significant difference between the groups and the healthy control group (n=30, P>0.05). When the fracture line was located in the volar 1/3 and dorsal 1/3 of the sigmoid notch, the length of the palmar superficial distal radioulnar ligament, the dorsal superficial distal radioulnar ligament and the dorsal deep distal radioulnar ligament were significantly different from that of the healthy control group (n=30, P<0.05). \u0000 \u0000 \u0000Conclusion \u0000The fracture pattern of type C distal radius can be visualized by fracture mapping technology. On the radiocarpal joint surface, the fracture line is concentrated around the lunate fossa; in the joint area of sigmoid notch, the fracture line is more concentrated in the middle 1/3 and the dorsal 1/3 of sigmoid notch. When the fracture line is distributed in the volar 1/3 and the dorsal 1/3 of sigmoid notch, it may lead to the risk of distal radioulnar ligament injury. \u0000 \u0000 \u0000Key words: \u0000Radius fractures; Biomechanics; Fracture mapping; Distal radioulnar ligament","PeriodicalId":67383,"journal":{"name":"中华手外科杂志","volume":"36 1","pages":"114-118"},"PeriodicalIF":0.0,"publicationDate":"2020-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46675133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
