A modification of the extension block Kirschner wire technique that is used for closed reduction of mallet fractures is described. Eighteen mallet avulsion fractures of the distal phalanx treated with this modification were included in this prospective study. The fingers affected were nine small fingers, eight ring fingers, and one long finger. Surgical indications included fractures involving more than 33% of the articular surface and fractures associated with subluxation of the distal phalanx that could not be corrected by closed reduction. The average joint surface involvement was 39.8%. At followup, only one patient had pain, and that was graded as minimal. Objectively, congruous and satisfactory joint surfaces were present in 17 patients. No patient had pseudarthrosis. The average active flexion of the distal interphalangeal joint was 81.1 degrees and the average extensor lag was 1.6 degrees. Neither pin tract infections nor migration of the pins occurred. The average followup was 27.3 months. This modification increased range of motion at the distal interphalangeal joint and showed a trend toward reduced permanent extensor lag when compared with the original method. This technique should be considered when treatment of the mallet fracture is being planned using the extension block Kirschner wire technique. 相似文献

BACKGROUND: The vast majority of metacarpal bone fractures are stable and are treated conservatively; however, when surgical intervention is to be preferred, many different operative procedures have been described. The purpose of this prospective study was to assess the anatomic and functional outcome of percutaneous transverse fixation with Kirschner wires (K-wires) of closed metacarpal neck, shaft. and intra-articular fractures of the base of the fifth metacarpal. METHODS: Twenty-four consecutive patients with 25 closed metacarpal fractures were treated with this technique between 1999 and 2001. Under fluoroscopy, closed reduction and osteosynthesis with three K-wires, one proximally and two distally, was performed on the fracture site. All patients were reviewed clinically and radiologically after 3 weeks, 6 weeks, and 3 months. RESULTS: The postoperative dorsal angulation ranged from 0 to 3 degrees. No measurable metacarpal shortening was observed. Callus formation was obvious in all fractures at 6 weeks. No complications were recorded, and all patients were cosmetically and functionally satisfied. CONCLUSION: Treatment of closed metacarpal neck, shaft, and intra-articular fractures of the base of the fifth metacarpal with percutaneous transverse pinning, using two K-wires distally and one proximally, has shown excellent functional and anatomic outcome. 相似文献

Treatment of humeral shaft fractures by closed fixation using multiple intramedullary Kirschner wires 总被引:1,自引:0,他引:1

BACKGROUND: The purpose of this study is to present the results of closed fixation of humeral shaft fractures with multiple intramedullary Kirschner wires. METHODS: Twenty-nine humeral shaft fractures in patients 14 to 60 years old were treated by closed fixation with multiple intramedullary Kirschner wires. Each patient was placed supine on the table and was administered general anesthesia. The fractured arm was held vertically up by a transolecranon traction, while the C-arm was kept parallel to the ground and opposite to the affected arm. A cortical window was created approximately 1.5 cm proximal to the olecranon fossa, after splitting the triceps. Under fluoroscopic control, multiple Kirschner wires were introduced retrograde therein, into the medullary cavity, to reach the humeral head. The wire tips were kept splayed to stabilize the fracture. Postoperatively, the limb was supported by an arm sling. RESULTS: Twenty-five fractures (86.4%) healed with excellent clinical and functional results, in an average of 11 weeks. Union was delayed in two patients, and one fracture had a nonunion after repeated trauma. Movements at the shoulder and the elbow were excellent to good in 27 patients (93%), whereas 2 patients (6.8%) had significant limitation of extension at the elbow. CONCLUSION: This technique has been found simple and effective in providing a stable fixation of transverse and short oblique fractures of the humeral diaphysis. Further study is required to evaluate this procedure in more extensive fracture patterns, as well as to compare the results with other methods of internal fixation. 相似文献

Fourteen cases of mallet fingers with a displaced large fracture fragment and/or a subluxated distal phalanx were treated by closed reduction using extension-block Kirschner wire. The follow-up evaluations took place after a mean of 9 months. The results according to Crawford's criteria were eight excellent, four good, one fair, and one poor. This technique is simple, is easier than other techniques for reduction of mallet fractures, and is associated with a low morbidity. 相似文献

After repair of a fractured zygoma, the fixed zygoma occasionally becomes displaced. This phenomenon — generally called “relapse” — is a complication that can be prevented by fixing plural sites with plates. However, this impairs blood supply to the bone, which causes atrophy. To solve this dilemma, we developed a new concept for fixing the zygoma. Fractured zygomas are fixed by combining plate fixation at a single site with transmalar fixation with Kirschner wires. This secures stability of the fixed zygoma without impairing its blood supply. We evaluated the stability of fractured zygomas fixed by our method by doing dynamic experiments using simulation models. The stresses at the screw-bone interfaces were significantly reduced by the additional transmalar fixation with wire, indicating that zygomas fixed by our method are less likely to relapse than zygomas fixed with a single plate. We also reviewed the outcomes of patients treated by our method, which indicates its clinical usefulness. 相似文献

The authors present an original fixation technique for pediatric olecranon fractures that avoids reoperation to remove hardware as compared with the standard fixation technique with Kirschner wires and tension band wiring as advocated by the AO technique. The authors' technique uses two percutaneously placed Kirschner wires to fixate displaced transverse and oblique olecranon fractures. Prior to the insertion of the wires, the fracture is reduced through a standard open approach. Augmentation of the pin fixation is achieved with absorbable sutures. Six patients have been treated with this technique, with a mean follow-up of 13 months. No immediate complications have been noted; one patient has a loss of extension of 10 degrees at the elbow. Radiographic results are good, with no loss of reduction. This technique avoids the need for reoperation for hardware removal without compromising the quality of reduction. 相似文献

The treatment of fractures of the lateral tibial plateau is still a subject of controversy. Many authors have emphasized the importance of early mobilization of the knee joint following fractures of the tibial plateau. However, local depression fractures of the tibial plateau occur quite frequently in elderly patients and have presented many difficult problems in management. In 1982, the authors developed a new method of closed reduction using the spring action of Kirschner wires for severely displaced local depression fractures of the tibial plateau. The principle of this procedure is to apply continuous positive pressure to the depressed fragment for its reduction and retention. By re-establishing stability in the fracture, active knee mobilization can be allowed from the beginning. Seven patients were treated with this procedure, and the results of short-term follow-up, ranging from three to 26 months, were promising as to the range of motion, stability and relief of pain. 相似文献

Open reduction and screw fixation of mallet fractures 总被引:2,自引:0,他引:2
Twelve patients with mallet fractures treated by open reduction and internal fixation with small screws were reviewed at an average of 31 months after surgery. The indication for surgery was a fracture involving more than one-third of the distal phalanx articular surface or with subluxation of the distal interphalangeal joint. Loss of reduction occurred in one patient and in another one screw loosened slightly without loss of reduction. There were no nail deformities, infections, or secondary procedures. The mean range of motion was from 6 degrees (range, 0-30 degrees ) (extensor lag) to 70 degrees (range, 60-90 degrees ) flexion. Ten patients had no evidence of degenerative changes, one had minor joint space narrowing and one had significant deformity. Open reduction and screw fixation with small screws can lead to satisfactory outcome in appropriate patients. 相似文献

PURPOSE: To evaluate treatment results of intramedullary fixation using multiple Kirschner wires for diaphyseal forearm fractures. METHODS: Between January 2001 and January 2004, 184 patients (122 men and 62 women) with 288 displaced diaphyseal forearm fractures underwent intramedullary fixation using multiple Kirschner wires. The wires were inserted by opening the fracture site because radiographic facility for closed pinning was unavailable. The time to union, functional recovery, and the complication rates were assessed. RESULTS: 11 patients were lost to follow-up, leaving 173 whose data was analysed. In 167 (97%) of the patients the fractures united, and in 14 (8%) of them union was delayed. The mean time to union for closed fractures was 13 (range, 7-16) weeks and for open fractures it was 15 (range, 12-22) weeks. The mean time in cast was 6 (range, 3-14) weeks. In all, 34/173 (20%) had complications: superficial infection (n=13), deep infection (n=4), cross-union between bones (n=4), open fracture 'needing' a skin graft (n=2), radial nerve palsy (n=3), paraesthesia (n=1), and non-union (n=7). Among the 173 analysed patients, the infection rate was 10% and the non-union rate was 4%. 130 (75%) of the patients had the wires removed; no re-fracture occurred after wire removal. Based on the Anderson criteria, 47 (27%) of the patients attained excellent, 78 (45%) satisfactory, and 39 (23%) unsatisfactory results. In 9 (5%) of the patients, union failed (7 plain non-union and 2 due to chronic osteomyelitis). CONCLUSION: Kirschner wires are much cheaper than plates and screws, and require minimal expertise for insertion and removal. They remain acceptable for stabilising displaced diaphyseal forearm fractures in developing countries. 相似文献

Introduction
Various surgical treatments such as extension block pinning have been proposed for acute bony mallet finger. We evaluated the clinical results of tension wire fixation technique for the treatment of nonunion of mallet fracture after failed mallet finger surgery.Materials and methods
Nine male patients were treated with open tension wire fixation for chronic nonunion of mallet fracture after extension block pinning surgery failed. The mean age was 29.3 years (range 18–47). We assessed bone union in simple radiographs. Crawford’s and Bischoff functional score was used to assess the functional outcome.Results
The mean follow-up period was 45.8 months (range 18–74). Clinical and radiographic bone unions were achieved in eight of nine patients with average time of 31 days (range 23–41). Mean extension lag at final follow-up was 7° (range 0–25). Four patients showed excellent, three patients showed good and two patients showed fair results on the Crawford’s score scale. With Bischoff functional score, all patients were categorized as excellent.Conclusions
Tension wire fixation can be a good second-line reconstructive surgery for the treatment of mallet fracture after extension block failed, so that patients can avoid arthrodesis or complex tendon transfer as a salvage procedure. 相似文献17.
