Unstable distal radius fractures treated by modified Kirschner wire pinning: anatomic considerations, technique, and results.

A modified technique of percutaneous Kirschner-wire pinning for unstable distal radius fractures is presented. Three to four pins are placed from the radial styloid process toward and through the dorsal, volar, and ulnar cortices of the proximal fracture fragment, respectively. Rotational stability is achieved by bending and counterblowing of the wire ends in the styloid process. Anatomic studies of cadaver wrists revealed possible lesions of the superficial radial nerve, the cephalic vein, and the tendons of the brachioradialis muscle or the thumb and wrist extensors, respectively. Nevertheless, in a follow-up of 80 patients after 1 year, no tendinous lesions nor any other serious complications were seen. Using the criteria of Green and O'Brien, the results were excellent in 66.25%, good in 20%, and fair in 8.75%.

[Management of acromioclavicular joint dislocation with the Wolter hook-plate. One year follow-up of 35 cases].

Wolter's hook-plate provides active abduction and forward-flexion of up to 90 degrees two days postoperatively. Prebending of the plate and a precise drill hole for the hook in the acromion prevents later impingement of the hook on the humeral head or subluxation in the acromioclavicular joint, respectively. According to the shoulder evaluation form of C.R. Constant, 33 of 35 patients operated on between 1987 and 1991 at the trauma departments in Schwaz/Tirol and Bad Ischl showed excellent results one year postoperatively.

[Anatomic studies of percutaneous bore wire osteosynthesis of the distal radius].

Modified percutaneous K-wire pinning has been used for unstable distal radius fractures groups A 2.2-3, A 3.1-3, B 1.1-2, B 2.1-2, B 3.3, C 1.1-3, C 2.1-3, and C 3.1-2 according to the ASIF-classification in 90 patients with good results. No tendinous rupture or any weakness respectively, infection or secondary dislocation either had occurred six months postoperatively. In five cadavers experimental anatomical studies had revealed possible lesions of the tendons of the brachioradialis muscle, the short and long wrist extensors, the long thumb abductor and his short extensor respectively as well as the superficial radial nerve and the cephalic vein. Abnormous sensations in the scar or in the region of distribution of the superficial radial nerve had occurred in every second patient but had subsided six months postoperatively. No permanent nerve lesion was found. There has been bleeding from the cephalic vein after the stab incision for exposure of the tip of the styloid process in every third patient but had healed uneventfully in every case.

A crook plate for treatment of acromioclavicular joint separation: indication, technique, and results after one year.

From 1987 through 1991 thirty-five patients underwent surgical repairs with Wolter's crook plates for acromioclavicular joint rupture. Sixteen of the patients had Post type IV lesions: another 19 patients had the same procedure for Tossy type III lesions. Active shoulder motion up to 90 degrees of abduction and forward flexion was allowed 48 hours postoperatively. All but one patient regained full range of motion at 8 weeks. Precise bending of the plate before insertion and an accurate drill hole for the crook in the acromion were essential to prevent impingement and also precluded ventral or cranial subluxation in the joint. Using the shoulder evaluation method proposed by Constant and Murley, after 1 year 94.28% (33 of 35) of the patients had excellent results.

A new approach to the subacromial space. Technique and 2-year results in 28 rotator-cuff repair cases.

We present a new approach to the subacromial space, consisting essentially of an osseous detachment of the deltoid muscle from the anterior and lateral rim of the acromion including the osseous origin of the coraco-acromial ligament. After acromioplasty and an eventual reconstruction of a torn rotator cuff, Kessler-sutures provide stable transosseous repair of the deltoid muscle. This method generally allows immediate active shoulder motion. 25 of 28 patients with rotator cuff ruptures alone or in combination with an impingement syndrome had good results according to the UCLA-score 2 years postoperatively. No serious complications regarding the function of the deltoid muscle or any failure of the accompanying acromioplasty occurred.

[Initial experiences with the humerus interlocking nail].

A preliminary report is given on the good results of eleven patients, who had been treated with a locking nail for a fracture of the humerus at three different trauma departments. No non-union, infection or radial palsy has been seen nor was there any neurovascular complication intraoperatively. Four patients had misalignments of up to 15 degrees, whereof three of them had combined varus-recurvation-angulations without functional or cosmetic sequelae. All but one had excellent functional results six months postoperatively. Bone healing could be confirmed three months postoperatively. Only transverse and spiral fractures of the second to fifth sixth had been treated until now, though open fractures up to the second degree can be managed too. Finally, some technical issues are considered, which include a better guiding device, the use of cancellous screws for proximal looking, a more oblique position of one of the proximal screwholes to obtain some kind of interfragmentary compression for appropriate fractures, and the use of a Williams-screwdriver.

Complications of interlocking nailing for lower leg fractures: a 3-year follow up of 102 cases.

Of the 109 patients treated by interlocking nailing for lower leg fractures between 1985 and 1990 at the A.ö.KH Schwaz and the LKH Bad Ischl, Austria, 92 underwent follow-up examination. Data were analyzed using a personal computer. Special attention was paid to fracture pattern, level, complications, and length of sick leave. Compared with a previous study, an increasing number of compound fracture patterns were evaluated. Except for 14 misalignments and two late infections after new injuries, no other serious complications were detected. Interlocking nailing can be highly recommended even for open fractures up to the second degree at any level from the second fifth to the fourth fifth of the tibia.

[Technique and results of modified percutaneous bore wire osteosynthesis of the distal radius].

A modified technique for percutaneous K-wire pinning of distal radius fractures is presented. With this method, three to four K-wires are introduced from the radial styloid process towards and through the dorsal, volar and ulnar proximal cortical wall, respectively. After the fracture fragments have been demonstrated to be stable, the wires are cut, bent over and fixed. Then a dorsal plaster splint is applied, which should be worn for 4-6 weeks, depending on whether or not there is a dorsal comminution zone. Fifty-five patients have been operated on by this method. At follow-up 6 months after the operation, no secondary dislocation, wire migration, infection, Sudeck syndrome or functional disturbance was seen. The advantage of this method is emphasized as compared with the usual, previously published method.

The influence of anatomic factors in elbow joint dislocation.

Twenty-seven patients with elbow joint dislocation were reviewed and treated between 1979 and 1983. For statistical reasons a sample of 27 elbows of healthy adults matched on age and sex were also roentgenographed. A computer-aided analysis of the carrying angle of the arm and the bow angle of the ulnar trochlear notch was made. The stability of the joint was tested clinically. The carrying angle showed no pathologic deviation. Values of the bow angle were at the lower end of the range given in the literature. Referring to these results, only normal anatomic constitutional factors predisposing to dislocation were found. Ligament repair was not routinely performed in this series. Nevertheless, recurrent dislocation did not occur and no relevant instability was detected. Except for injuries with osseous lesions, conservative treatment is advisable in most cases.

[Elbow joint dislocation. Diagnosis, therapy, results].

Thorough knowledge of the anatomy and biomechanics in the elbow joint together with an special reference to constitutional variations is an important factor in understanding the pathomechanisms of its dislocation. We are presenting 27 case-reports of elbow-dislocations treated at the I. University Clinic for Traumatology in Vienna between 1979 and 1983. The so-called carrying angle showed no pathological deviation besides a tendency to cubitus valgus and hence elbow-joint to dislocation. Our results showed clearly that conservative treatment is possible and advisable in most cases. Only dislocation with osseous lesions and/or a tendency to redislocation after reduction should be operated on.

A new technique for anterior acromioplasty.

A new approach to anterior acromioplasty is presented. Using the oscillating saw of the ASIF-miniset, the deltoid muscle is detached off the acromion together with an osseous slice. This technique provides a stable reduction of the muscle at the end of the operation and avoids painful periostitis postoperatively. In so far, early functional recovery can be undertaken as soon as three weeks postoperatively.

A locking nail for fractures of the humerus.

We reviewed 19 patients treated for upper arm fractures using Seidel's locking nail system, which allows for early function after operation. The overall results were good with no cases of pseudarthrosis, infection or radial nerve palsy. All the patients regained full shoulder movements with no evidence of rotator cuff lesions.

[Interlocking nailing of compound lower leg fractures].

Seventy-eight patients with lower leg fractures treated by interlocking nailing at the hospital in Schwaz were reviewed. The overall results were satisfying. There were nine misalignements, two of which underwent subsequent correction. Two infections took place, one after precipitant bone grafting at another place and another one following new trauma. Seven first and five second degree open fractures had an uneventful healing. Interlocking nailing was found to be the treatment of choice for compound fractures with open or closed soft tissue injury of first or second degree after Tscherne. Compared with a previous study about ski injuries, complex fracture patterns combined with severe closed soft tissue lesions showed an increasing incidence during the last ten years. This contrast with the decreasing number of ski injuries in general.

Percutaneous cerclage wiring and interlocking nailing for treatment of torsional fractures of the tibia.

A new method for treatment of torsional tibial fractures allows full weight bearing two days post-operatively. Percutaneous cerclage wiring (Gotzes method) is done after a manual anatomic reduction on a normal fracture table, followed by static interlocking nailing. Compared to other methods, no extensive exposure is necessary, which helps preserve the periosteal blood supply. These considerations, as well as an early axial pressure load and an almost absolute stability, might explain the roentgenographic and clinical evidence that bone healing with minimal callus formation occurs six to eight weeks postoperatively.

[Interlocking nailing and percutaneous cerclage by Götze's method in caring for tibial torsion fractures--a preliminary report].

A new method for treatment of torsional crural fractures is presented which allows immediate weight-bearing postoperatively. It consists of percutaneous cerclage wires (Götze's method) on a normal fracture table, after which static interlocking nailing is undertaken. No excessive medullary reaming is necessary. The almost absolute stability brought about by this method helps to avoid such complications as nonunion or delayed healing and diminishes the risk of infection. This is a preliminary report on the first ten cases with overall good results.

Cerclage for torsional fractures of the tibia.

We report the technique and results of percutaneous cerclage used in treating 186 torsional fractures of the tibia, most of which were due to skiing accidents in young patients. It is recommended only for this type of fracture and has the advantages of simplicity, a low rate of complications and a relatively brief period in hospital.

[Percutaneous Goetze cerclage in torsion fractures of the tibia. A computer-assisted follow-up of 186 cases].

186 lower leg torsional fractures treated via percutaneous cerclage wiring (Götze's method) yielded good to very good final results. There were no intraoperative complications such as lesions of the vessels and nerves. The number of refractures (1.61%), the incidence of delayed healing (4.3%), infections (3.23%) and misalignments (6.9%) are all comparable with data that can be found in the literature. No pseudoarthroses were seen. Besides low rate of complications and the rapidity of the procedure, the simplicity and low cost of the required instrumentarium are also very attractive. The fact that the patients remain in the hospital for a short while only, is yet another contribution to keeping the cost of general health care low in these times of exploding expenditure for medical attendance.
