Description
Technical Field
The utility model relates to the field of surgical instruments, in particular to an external osteotomy fixing support for treating ulna impaction syndrome.
Background
Ulna impingement syndrome is a group of clinical syndromes caused by impingement of ulna distal ends and ulnar triangular fibrocartilage complexes of wrist joints and heavy load on ulnar sides of wrist joints. The bones of the wrist, such as the lunate cartilage and the triangular bone, are also pathologically changed due to long-term impact and abrasion, so that the pain of the wrist, the limited movement of the wrist joint and the reduced grip strength of the affected limb appear. With the progress of the disease, the function of the wrist joint will be seriously impaired, which will bring serious impact on the daily life and work of the patient. In the early stage of the disease, conservative treatments such as braking and physical therapy can be selected, but if the symptoms become more severe and the conservative treatment is ineffective, surgical treatment is required. At present, the most fundamental and effective method for clinically correcting the positive variation of the ulna is ulna shortening. The ulna shortening operation shortens the length of an ulna by cutting the bone, so that the normal anatomical structure of the lower ulnar and radial joints is restored, and the ulnar pressure of the wrist joint is correspondingly reduced. Two major technical difficulties of surgery are: osteotomy angle and osteotomy length. Currently, the commonly selected osteotomy angles include: transverse osteotomy and oblique osteotomy. The latter has better anti-shearing and anti-rotation capability than the former, and can shorten the bone healing time due to the increase of the contact area of the osteotomy end. However, oblique osteotomy requires that the planes of the two osteotomies are parallel to each other, otherwise, the force line of the ulna is changed after the ulna is shortened, so that the anatomical structures of the lower ulna, the radius joint and the wrist joint are changed, and a satisfactory treatment effect is difficult to obtain. The osteotomy length should be determined according to the number of positive ulna variations of the preoperative wrist alignment plate, and should be kept between-1 and 1mm after osteotomy. However, in the actual operation process, most surgeons determine the length of the osteotomy by visual inspection, and it is difficult to perform accurate osteotomy, so that the positive variation of the ulna is not completely corrected or over-corrected. To solve the problem, the chinese patent CN211560317U discloses a sliding ulna shortening osteotomy plate. However, in the operation process, the soft tissues around the ulna need to be widely stripped, the operation wound is large, and the blood circulation damage to local tissues is large. And the steel plate has larger volume, is easy to irritate surrounding soft tissues when remaining in a body, causes extensive scar hyperplasia, and has uncomfortable symptoms after partial patients operate. And the internal fixing device is required to be removed when the osteotomy surface is completely healed. The operation of removing the internal fixation needs to be carried out again for soft tissue stripping, so that on one hand, the patient receives secondary trauma, and on the other hand, the mental and economic burden of the patient is increased.
