Clinical analysis of pelviscopic classic intrafascial Semm hysterectomy.

STUDY OBJECTIVE: To evaluate the efficacy of pelviscopic classic intrafascial Semm hysterectomy (CISH). DESIGN: Review of hospital records of 90 women undergoing pelviscopic CISH between April 1993 and June 1994. SETTING: Department of Obstetrics and Gynecology at a university teaching hospital. PATIENTS: Sequential sample of 90 women undergoing pelviscopic intrafascial hysterectomies. INTERVENTIONS: All of the hysterectomy procedures were performed in the classic manner with grasping forceps, scissors, ligatures, and sutures. No lasers, electrocoagulation, or stapling devices were used. MEASUREMENTS AND MAIN RESULTS: Indications, associated procedures, surgical outcomes, and complications were analyzed. The most common surgical indication was leiomyomata uteri. No major complications occurred even in patients who had extremely large leiomyomata. The mean uterine weight was 207.49 +/- 104.9 g. The average operating time (169.89 +/- 56.19 min) was consistent with that of other methods. Blood loss (160 +/- 182 ml) was lower than during conventional abdominal hysterectomy. No procedure was converted to laparotomy. CONCLUSIONS: Pelviscopic CISH is truly a minimally invasive and organ-preserving surgery, and in our study was associated with significantly low morbidity and no major complications. Pelvic floor support is maintained and the ureters are not in danger. Coring out the cervix with the calibrated uterine resection tool may prevent the development of cervical cancer. Therefore, we think that CISH may be an acceptable technique for benign uterine disease.

Single hemicerclage for lateral type B malleolar fracture--a novel, minimal and reliable osteosynthesis.

AIM OF STUDY: To investigate the short- and long-term outcome of patients with isolated lateral malleolar fracture type B treated with a single hemicerclage out of metallic wire or PDS cord. METHODS: Over an 8-year period 97 patients were treated with a single hemicerclage for lateral malleolar fracture type B and 89 were amenable to a follow-up after mean 39 months, including interview, clinical examination and X-ray controls. RESULTS: The median operation time was 35 minutes (range 15-85 min). X-ray controls within the first two postoperative days revealed an anatomical restoration of the upper ankle joint in all but one patient. The complication rate was 8%: hematoma (2 patients), wound infection (2), Sudeck's dystrophy (2) and deep vein thrombosis (1). Full weight-bearing was tolerated at median 6.0 weeks (range 2-26 weeks). No secondary displacement, delayed union or consecutive arthrosis of the upper ankle joint was observed. All but one patient had restored symmetric joint mobility. Ninety-seven percent of patients were satisfied or very satisfied with the outcome. Following bone healing, hemicerclage removal was necessary in 19% of osteosyntheses with metallic wire and in none with PDS cord. CONCLUSION: The single hemicerclage is a novel, simple and reliable osteosynthesis technique for isolated lateral type B malleolar fractures and may be considered as an alternative to the osteosynthesis procedures currently in use.

Arthroscopic suture tying: A comparison of knot types and suture materials.

PURPOSE: The purpose of this study was to determine the structural properties of 3 arthroscopically tied knots using 2 different suture materials: the French knot, the Duncan loop knot, and the original Revo knot. TYPE OF STUDY: Cohort analytic study. METHODS: The sutures used were No. 1 PDS II, an absorbent monofilament, and No. 1 Ethibond (Ethicon, Somerville, NJ), a braided nonabsorbent material. The resulting 6 suture-knot combinations were individually tested to failure in both open- and closed-loop configurations. RESULTS: The French knot showed the greatest strength compared with the Duncan loop and the Revo knot with both No. 1 Ethibond and No. 1 PDS II sutures (P <.05). The No. 1 Ethibond exhibited higher initial stiffness than the No. 1 PDS II for all 3 knot types (P <.05). Results were similar for both open and closed-loop configurations. Also, the French knot failed predominantly by suture breakage instead of knot slippage for both suture materials. CONCLUSIONS: The results of this study suggest that, among the suture and knot combinations investigated in this study, the arthroscopic repair of musculoskeletal injuries should be performed using the French knot and No. 1 Ethibond suture.

Simplified arthroscopic suture passing using a suture loop.

Arthroscopic procedures for shoulder pathology are becoming more popular. Passing braided nonabsorbable suture for repair of intra-articular tissue can be technically difficult because advancing this suture through tissue is a 2-step process. The use of a suture loop with Spectrum suture hooks (Linvatec, Largo, FL) simplifies braided suture passing, and eliminates the use of expensive suture shuttles. This technique simplifies the use of nonabsorbable suture in arthroscopic shoulder procedures.

Intraoperative computed tomography with the mobile CT Tomoscan M during surgical treatment of orbital fractures.

Up to now it has only been possible to monitor the alignment of orbital floor fractures postoperatively with a computed tomography (CT) examination with coronal sectioning. If this showed an incorrect positioning, renewed surgery and anaesthetics were often required. The purpose of this study was the implementation and definition of the spectrum of indications for intraoperative CT examinations while keeping patient radiation exposure to a minimum. Thirty-two orbital fracture cases were examined pre- and intraoperatively using the mobile computer tomograph Tomoscan M in coronal sectioning. In this patient collective, 12 cases showed an isolated orbital floor fracture and twenty cases an orbital floor fracture associated with a zygomatic fracture. The technical prerequisite for these examinations was the construction of a suitable radiolucent operating table which permitted coronal sections to be made with the CT-Gantry tilted. The authors aimed to reduce radiation exposure by optimizing the technical setting parameters and closely defining the scan region for the operator. In three of 32 cases there were no surgical indications following clinical and preoperative CT examination. In three of the 20 cases with associated zygomatic fracture a closed reduction with a reduction hook was carried out, and no revision was necessary after the intraoperative CT examination. In 26 cases an open reduction was carried out. Of these open reduced fractures, four had to be revised after intraoperative CT monitoring; one of the isolated orbital floor fractures and three of those associated with a zygomatic fracture. Intraoperative CT monitoring of orbital floor fractures is considered a useful surgical aid. Its advantages are immediate monitoring of the surgical reduction, the presence of the surgeon during scanning enabling him to determine directly the relevant sections to scan, and the resulting radiation exposure.

[20 years' experience with extracorporal septoplasty].

Even today the difficult septum presents a surgical problem. A severe septum deformity is caused mostly by an accident or is seen in patients with malformation like CLP-deformity. It is characterized by a massive deformation in all levels with a consecutive blocking of one or both airways. Such severe septal deformities cannot be corrected properly by classical septoplasty techniques. Therefore we suggest an extracorporal septoplasty, where the whole septum is taken out and by different techniques a new septal plate is reconstructed and then replanted. From 1981 to 2001 we operated 1855 patients and improved this method constantly, especially the safe septal fixation after replantation. Follow-ups showed that even in severe deformities a revision rate of only 5 % respectively 7 % was found. Therefore we conclude the extracorporal septoplasty with its refinements can also be recommended also to the less experienced rhinosurgeon.

[Resorbable pin refixation of an osteochondral fracture of the lateral femoral condyle due to traumatic patellar dislocation: case management, follow-up and strategy in adolescents].

AIM: Intraarticular osteochondral fractures resulting from traumatic patellar dislocation in children are reported most frequently between 13 and 15 years of age. Fracture localization concerns, apart from loose intraarticular bodies, the inferiomedial patellar facet and the lateral femoral condyle. Osteochondral fractures of the lateral femoral condyle with more than 50 % of its surface are extremely rare and reported infrequently. METHOD: We report a traumatic patellar dislocation in a 14 year old patient that let to an osteochondral fracture of the lateral femoral condyle. MRI-scan demonstrated an extensive fracture size concerning more than 50 % of the condylar surface with intraarticular dislocation. Initially arthroscopic surgery followed an open reduction and internal refixation of the osteochondral fragment with resorbable, poly-p-dioxanon pins. RESULTS: Follow-up MRI-scan revealed 7 weeks after surgery an adequate repositioning of the fragment with correct pin placement. Second-look arthroscopy demonstrated an osteochondral reintegration of the fragment within a period of 7 months after prior surgery. CONCLUSION: Resorbable poly-p-dioxanon pins as a mean for refixation of an osteochondral, intraarticular fracture in an adolescent, with an arthroscopic confirmed acceptable result, seem to be a considerable therapy option.

[Refixation in osteochondrosis dissecans with resorbable material using magnetic resonance tomography in follow-up monitoring].

A new method for refixation of osteochondritis dissecans and osteochondral flake fractures by using absorbable pins, fibrin adhesive and autologous spongiosa transplantation is described. The diagnostics can be improved by using MR (magnetic resonance imaging) to demonstrate the preoperative status of the defect as well as the postoperative reintegration of the flake, bone vitality and continuity of the joint cartilage. MR information is an excellent addition to the conventional radiograms for preoperative planning as well as for postoperative decision when to allow daily and sports activities. The clinical and radiological preliminary results of the described method show a complete reintegration in all cases of osteochondritis dissecans of the femur condyle.

[Suitability of resorbable sutures in the treatment of corneal wounds].

In a series of cataract operations with a corneal incision PDS 10-0 absorbable sutures were tested. In contrast to deeper PDS sutures, such as are used in corneoscleral incisions, the corneal sutures opened as early as between 13 and 30 days postoperatively in 5 out of 7 cases. Postoperative irritation was more severe and lasted longer than is usual when non absorbable sutures are used. This was probably caused by ends of the thread which had not yet been absorbed, resulting in a foreign body irritation of long duration. Altogether, absorbable PDS 10-0 sutures are only suitable for corneal wound closure to a limited extent.

Biomaterial pretreatment with ECGF to augment endothelial cell proliferation.

ECGF, a polypeptide of bovine hypothalamic derivation, is the most potent endothelial cell mitogen known, with mitogenic and chemotactic effects well demonstrated in vitro on human endothelial cells. These effects are synergized by heparin. In vivo re-endothelialization of blood-contacting biomaterials may be enhanced by bonding ECGF and heparin to prosthetic surfaces. Long woven Dacron (24 mm) and woven PDS vascular prostheses were treated first with human plasma fibronectin (10 micrograms/cm2). Porcine sodium heparin (20 micrograms/cm2) was added by means of fibronectin's heparin affinity. Pure 125I-ECGF (95% alpha, 5% beta; 1 ng/cm2) was next fixed by the heparin affinity of ECGF and followed by a second heparin layer (20 micrograms/cm2) to synergize with and stabilize ECGF. 125I-ECGF adherences were determined by scintillation counts. Attachment efficiency averaged 25%. Prostheses were interposed into rabbit aortas and harvested in triplicate from 0 to 30 days to establish in vivo washout curves. After explantation, residual 125I-ECGF was eluted from prostheses, and intact ECGF was identified by SDS gel electrophoresis. Similarly prepared but nonradioiodinated Dacron and PDS prostheses were explanted after 7 days and their ECGF eluted off for in vitro activity documentation. This ECGF retained its mitogenic properties, causing a 1000% to 1200% increase in 3H-thymidine incorporation into newly synthesized DNA in test murine LE-II cells. Fibronectin-heparin-ECGF fixation to blood-contacting biomaterials may enhance spontaneous re-endothelialization and/or hasten the confluence of transplanted endothelial cells.

A comparison of interrupted and continuous sutures for tracheal anastomoses in sheep.

OBJECTIVE: To study the tensile strength of tracheal anastomoses. DESIGN: Experimental study. SETTING: University medical school laboratory, Germany. ANIMALS: 15 sheep. INTERVENTIONS: Tracheal anastomoses with three different suturing techniques: a continuous suture and interrupted sutures with either a monofilament or a polyfilament material. Anastomoses were tested to breaking after being in place for 1, 2, 4, 8 or 24 weeks. RESULTS: After one week, with all three materials, the trachea broke at the anastomosis. In animals that survived longer, the trachea broke further away from the anastomosis. There was no significant difference between the mean values of the breaking force for continuous sutures and single interrupted sutures (p = 0.9). CONCLUSION: The suturing technique (continuous or interrupted) has less relevance for the tensile strength of the anastomosis than in vitro experiments suggest.

The kinematics and kinetics of slipknots for arthroscopic Bankart repair.

An apparatus has been developed to enable the in vitro measurement of the kinematics and kinetics of a slipknot, both while the knot is being tightened and with the knot in place and the tension removed. During tightening, the apparatus provides a linearly increasing resistance, which may be considered analogous to the resistance experienced when the labrum is drawn toward and apposed to the edge of the glenoid cavity during a Bankart repair. The tension to close the knot is measured with a tensiometer, in tandem with the closure of the capsule model onto the bone anchor, which is measured with a datalogger. The tightening tension was limited to 25 N and intraoperator and interoperator comparisons were made for four knots tied by six participants. Failure of a knot was taken to be reverse slippage of 2 mm. A second criterion of ease of slide was used to assess each knot. We found wide interoperator variability with regard to slipknot tying. A methodology for quality control of slipknot tying is presented.

Acromioclavicular reconstruction augmented with polydioxanonsulphate bands. Surgical technique and results.

During a 5.5-year period, we treated 64 patients with acute acromioclavicular separations by surgical reconstruction. According to the classification of Rockwood and Matsen, 54 patients had type III lesions, 1 patient had a type IV lesion, and 9 patients had type V lesions. Both the coracoclavicular ligaments and the ligaments of the acromioclavicular joint were reconstructed. An additional ligamentous augmentation was performed using completely resorbable 5- and 10-mm polydioxanonsulphate bands. Forty-five patients (70%) were re-examined at 2 to 7.5 years after surgery (mean, 32 months). The results were good or excellent in 40 cases (89%). Forty-one patients (92%) achieved a range of motion with an abduction deficit of less than 20 degrees. Calcifications in the area of the coracoclavicular or acromioclavicular ligaments did not affect the final range of motion. Complications consisted of one subcutaneous infection, one deep infection, and one failure of the reconstruction. Augmenting the reconstruction with polydioxanonsulphate bands allowed an early functional postoperative treatment. With this procedure, patients do not require removal of an implant, and complications from breakage or migration of metal implants are avoided.
