Surgical nuances on the treatment of giant dumbbell cervical spine schwannomas: description of a challenging case and review of the literature
2016
We report a case of a giant intra and extradural cervical schwannoma in a patient affected by a severe myelo-radiculopathy. Clinical features, diagnosis and the issues concerning the surgical management of this benign tumor are discussed. We also review similar cases previously reported in the literature. A 50-year old caucasian woman was complaining of a 1 year of neck pain and worsening motor impairment in all four limbs causing the inability to walk. Neuroradiological assessment revealed a suspected schwannoma involving the nerve roots from C3 to C5, compressing and deviating the spinal cord. The vertebral artery was also encased within the lesion, but still patent. A posterior cervical …
Acetabulumfrakturen im Alter
2002
Acetabular fractures in elderly patients are rare injuries, but their incidence is increasing. Poor bone quality due to osteoporosis and an increased operative risk due to concomitant disease are factors complicating surgical therapy. Literature does not provide generally accepted treatment protocols. In a 4-year period, 27 patients who were 65 years or older and who had an acute displaced fracture of the acetabulum were admitted to our department. Four minimally displaced and stable fractures were managed conservatively. Internal fixation was performed in 16 cases. According to the Merle d'Aubigne score, in 15 out of 18 surviving patients excellent or good results were found. Treatment str…
Callus distraction of the femur and tibia. Experience with the Monofixator - indications for reosteosynthesis
1998
In a 4-year period, 18 patients underwent callus distraction of the femur or tibia with the use of a unilateral external fixator. Twelve patients had post-traumatic bone loss resulting from complex lower-limb fractures. The bony defect was located in the tibia in 11 cases and in the femur in one case. All patients had major associated soft-tissue lesions. The length of the bony defect averaged 6.25 cm. Eight fractures were infected at the beginning of treatment. Six other patients underwent callus distraction for reasons of limb shortening. Five femora and one tibia were lengthened. The average increase in length was 6.5 cm. There were no fixator-related complications during distraction. Th…
Ergebnisse nach primärer ungebohrter Tibianagelung von Unterschenkelfrakturen mit schwerem offenem oder geschlossenem Weichteilschaden
1996
Primary stabilization was performed in 72 tibial fractures with sever open (n = 37) or closed (n = 35) soft tissue injury using unreamed interlocking nails. In 60 (83%) cases the fractures healed without additional procedures. There were 2 cases of osteitis, but both these fractures healed after removal of the nail or after reamed nailing. In 9 patients with delayed union reamed nailing (n = 8) or bone grafting (n = 1) led to healing. In 1 patient with hypertrophic pseudarthrosis, union was achieved after substitution of a reamed nail for the anreamed nail. The infection rate was similar to that observed with external fixation. More secondary procedures, such as bone grafting or a change of…
Proximale Verankerung von Hüft-Endoprothesen mit poröser Oberfläche: 6-Jahres-Ergebnisse
2008
PROBLEM The anatomically shaped pcl (ESKA) total hip replacement has a porous coating of the proximal stem and the cup to allow for bony ingrowth. The tip of the stem is polished. METHOD We report the results of 96 THR 6.2 years (5.25-6.7) after implantation. RESULTS There were no revisions during this period. One stem showed radiographic loosening at follow-up. There was stress-shielding in 9.4% in contrast to the concept of proximal fixation. Thigh-pain was found in 9.4%. One patient demonstrated disabling thigh-pain despite radiologic bony ingrowth. By drilling the femur distal to the tip of the stem a remarkable relief was achieved. CONCLUSION Despite numerous cases of stress-shielding …
First-in-man permanent laparoscopic fixation free obliteration of inguinal hernia defect with the 3D dynamic responsive implant ProFlor-E®. Case repo…
2020
Abstract Introduction In the case of inguinal hernia recurrence after primary anterior repair, international guidelines strongly suggest a posterior laparoscopic approach. The 3D dynamic-responsive prosthesis for inguinal hernia repair ProFlor-E® has recently been introduced to the market. The present report describes the results of the first-in-man laparoscopic inguinal hernia repair carried out with ProFlor-E®. Presentation of case A 71-year-old male Caucasian presented with recurrent inguinal hernia after primary anterior repair. A fixation free TAPP procedure with ProFlor-E® was planned. Implant delivery and placement to obliterate the defect was quick and safe. Postoperatively, startin…
The Surgery of Neglected Distal Humerus Fractures in Children and Adults
2008
The restoration of function after a neglected distal humerus fracture presents a formidable challenge to the surgeon because of both the complexity of the regional anatomy and the proximity of numerous neurovascular structures. Inadequate or unstable fixation, a failure to reposition the articular fragments anatomically, prolonged post-operative immobilization, or the development of soft-tissue complications will result in substantial disability for the patient. Complications after injuries affecting a child’s elbow are common due to understimating the severity of the injury on the native X-rays where the growth plates and cartilage structures can not be seen.
Internal Fixation of Proximal Humeral Fractures: Current Concepts
2003
Fractures of the proximal humerus are an increasingly common type of injury. Mainly elderly patients with osteoporotic bone are affected. Whereas non-displaced and stable fractures are managed successfully with conservative treatment, there is no general agreement on the surgical strategy for displaced and unstable two- to four-part fractures. The clinical outcome is influenced by the fracture type and concomitant injury to the rotator cuff. Extensive surgical manipulation of the soft tissues, non-anatomic and/or unstable fixation as well as technical errors are important contributing factors to poor clinical results. Goals of surgical treatment are to restore anatomy, to achieve fixation t…
Ultrasound-guided spinal fracture repositioning
1998
The management of narrowing spinal fragments in the operative treatment of spinal fractures remains an open question, in particular when the procedure is performed by a posterior approach. This article describes the use of intraoperative ultrasonography during spinal surgery. From 1990 to 1997, 116 spinal fractures were treated operatively at our clinic. Stabilization of the spine was achieved with the AO fixateur interne and the AO USS, respectively (Synthes, D-79224, Umkirch, Germany). For 60 cases who had a fractured posterior vertebral surface dislocated into the spinal canal, we used intraoperative ultrasonography to monitor the repositioning of the narrowing fragments. The patients un…
The use of a new kind of low profile retractor for arteriovenous fistula procedure simplifies and speeds up the intervention
2009
Purpose The aim of this study was to demonstrate the effectiveness of a new kind of disposable surgical retractor in arteriovenous fistula (AVF) procedures in order to achieve an easier, faster and safer surgical intervention. Methods Between January and June 2008, 22 AVF procedures were performed using the 3PAWS ReeTrakttrade; (Insightra Inc. - Irvine, Ca., USA) a self-retaining, low profile retractor. An equivalent patient sample, in which an AVF was performed using conventional retraction devices, was considered for comparison of the intra- and post-operative results. Results In all of the 22 AVF procedures performed, the ReeTrakt™ system has simplified the performance of the surgical te…
