Alpine ski sports changed rapidly in the last decade. Complex fractures of the proximal tibia, typically seen in high energy trauma, has been seen more frequently and more often related to alpine skiing.

The aim of our study was to identify reasons for proximal tibia fracture in alpine skiing and observe the outcome.

All patients with proximal tibia fractures related to alpine skiing, which were treated in our two trauma centers were included. The patients received a questionnaire at the emergency department, dealing with accident details and the skiing habits. The fractures were classified according to the AO fracture classification scheme. The follow up was performed at least one year after trauma with the Lysholm, the Tegner activity, as well as the WOMAC VAS Score.

Between 2007 and 2010 a total of 188 patients with proximal tibia fractures caused by alpine skiing were treated. 43 patients had a type A, 96 patients a type B and 49 a type C injury. The incidence was increasing over the period continuously. The main trauma mechanism was an accident without a third party involvement with an increased rotational and axial compression impact. All outcome scores were related to fracture severity with significant worse results for the type C fractures.

In conclusion, proximal tibia fractures are an increasing and serious injury during alpine skiing. Further technical progress in skiing material should focus on these knee injuries in future.

Introduction

Proximal tibial fractures frequently present in combination with other injuries which also have to be treated surgically. Recent publications do not consider isolated proximal tibial fracture (mono-injury) and combined injuries which include tibial fractures as two seperate medical entities. We therefore asessed the influence of additional injuries on treatment and outcome of the proximal tibial fractures.

Methods

We admitted 84 patients which were consecutively treated in our department from 01.01.2007 to 31.12.2009. Only C1 to C3 fractures (x-ray, ct-scan), according to AO classification with subsequent open reduction and internal plate osteosynthesis were included. Additionally we looked for additional injuries cause by the accident, numbers of operations and strategie of operative treatement, traumaspecific vs. postsurgical complications and inpatient days. At the follow-up investigations one year post surgery, Lysholm- and WOMAC-Score as well as Tegner-Activity-Index were used.

Since the introduction of carving skis, the injuries of the tibia is changing from simple fractures of the diaphyse to complex fractures of the epiphyses, according to high energy traumas. There are no studies about results of the treatment and consequences after winter sport accidents.

Method: Prospective documentation of all proximal tibia fractures after winter sport accidents, which were treated between 01.12.2006 and 31.04.2009 in the Trauma Department of the Klinikum Garmisch-Parten-kirchen, Germany. X-Rays and CT scans were classified according to the AO –Classification. Operations, complications, co-injuries and the hospital stay were analysed. We performed the Lysholm score, WOMAC Knee-score and the Tegner-index on the day of injury, 6 months, 12 months, and 2 years after injury.

Results: 78 patients had a proximal tibia fracture following a skiing accident, 36 Male and 42 female. All except two patients had a monotrauma of the proximal tibia. Mean age 46 ± 15 years. 17 types A.1.3, 41 types B and 18 types C3 fractures. 4 patients developed a compartment syndrome, one patient had a lesion of the n. peroneus. 65 patients were operated in our hospital. In 8 patients we performed a conservative treatment. The mean hospital stay was 12 ± 7.5 days. In 15 patients a menisci reconstruction was necessary. 6 patients had a postoperative complication: 3 thromboses, 2 cardiac decompensations, 1 wound healing problems. By now 42 patients were ready for follow-up. So far the mean follow-up time is 13.8 months. The Lysholm score was at 12 months (n= 22) 78 ± 20 points. The Tegner score was pre-injury 6.2 ± 1.1 and 12 months post-injury 4.1 ± 1,8. The results of the WOMAC score show an improvement in the subcategories pain and function in all patients. In the subcategory stiffness only the type A and B fractures show an improvement during the follow-up.

Conclusion: The proximal tibia joint fractures are a serious injury. The most patients’ activity level is tremendously reduced. The major problem after one year seems to be the ligament instability of the knee. A beginning knee arthritis after one year becomes relevant only in the type C fractures. More effort for the prevention of the proximal tibia fractures while skiing is necessary.

Introduction: The ventral thoracoscopic spondylodesis of the thoracolumbal spine is an elegant treatment strategy in cases of incomplete vertebral burst fractures.

Materials and Methods: In the years 2002/03 29 patients with incomplete burst fractures of the thoracolumbal spine, were treated by a ventral thoracoscopic spondylodesis and were included prospectively. The individual treatment plan depended on the patient’s general condition and the vertebral stability. The data acquisition was done according the DGU guidelines of documentation preoperative, postoperative, and after 3, 6, 12, and 18 months. After 5 years a follow-up examination was performed in 21 of these patients (9 men, 12 women, average age: 46.3 years, follow-up rate: 72%). 9 patients were treated ventral only. In all of them the ventral spondylodesis was done monosegmental with autologous iliac crest. In 12 cases a dorsoventral procedure was performed, 5 patients ventral monosegmental with iliac crest, and 7 patients bisegmental with cage. Parameters of interest were the bisegmental kyphotic angle, the SF-36 score, the visual analogue scale (VAS), and the morbidity of the surgical approach.

Results: The 5-year results of the 21 patients dependent on the treatment strategy:

5 years/Reposition- Loss of Reposition- VAS- PSC (SF36)- MCS (SF36)

Ventral only/3,4°- 2,5°- 72- 48- 55-

Dorso-ventral (total)/7,1°- 6,0°- 79- 49- 50

Ventral monosegmental/9,8°- 5,2°- 81- 54- 54

Ventral bisegmental/4,5°- 6,3°- 77- 44- 56

Only three patients complained of intermittent weak pain sensation at the region of the thoracoscopic approach (14%). During the 5 years one revision surgery was performed because of the development of an incisional hernia.

The computertomographic controls of the 14 patients who gained a monosegmental spondylodesis with an iliac crest showed in 12 cases a complete osseous consolidation (86%) after 5 years. In the other two cases the osseous consolidation was only partly visible with an area of consolidation of more than 30% (14%). In both cases a sufficient stability was existent. 4 patients (29%) had no symptoms at the site of the iliac crest removal. 8 patients (57%) reported of weak residual pain, 2 patients (14%) reported of more intense pain sensation.

Conclusions: After 5 years the ventral thoracoscopic spondylodesis of the throracolumbar spine after incomplete burst fractures prove to be a save and successful therapy strategy. There are no significant differences between the isolated ventral spondylodesis and the dorsoventral spondylodesis in respect of loss of reposition of the bisegmental angle, persisting pain sensations, and quality of life after 5 years. The ventral thoracoscopic monosegmental spondylodesis seems to be by trend superior to the bisegmental strategy in respect of the physical summary score.


Aims: Aim of this prospective clinical study was to prove whether there are clinical differences between ms VTS with interposition of an autogenic tricortical bone graft alone and a consecutive dorso-ventral procedure for A 1.2 and A 3.1 fractures of the thoracic and lumbar spine.

Materials und Methods: From 01/2002 to 12/2003 298 pat. with traumatic fractures of the thoracic and lumbar spine were treated and had a prospective clinical and radiological follow-up according to the mc-study of the DGU. For 29 pat. (14 m, 15 f; mean age 33 y) ms VTS was performed either isolated (10) or consecutive after dorsal instrumentation (19). Over the post-OP course with a follow-up of 18 mo. the pat. underwent a questionnaire concerning the morbidity at the surgical approaches, the subjective back function and the Odom-score. The osseous integration of the graft and the resulting loss of correction were investigated within the follow-ups 3, 6, 12 and 18 mo. post-OP.

Results: Concerning the anterior column 83% of the pat. had type A 3.1.1 fractures. All pat. with type B and C injuries underwent consecutive dorso-ventral instrumentation in 2 sessions. In one case revision surgery with bisegmental replacement of the affected vertebral body by a distractible cage was performed due to osteolysis of the bone graft. The other 28 pat. had no intra- or post-OP complications associated with the autogenic bone graft. At the 12 mo. follow-up osseous integration of the bone graft was observed in 28/29 in the CT-scans. The dorsal instrumentation could be removed in 8 of the 19 pat. with a dorso-ventral procedure after a mean of 12,6 mo. The measurements of the CT-scans at 18 mo. showed an average loss of correction (bisegmental) of 1,5° in the isolated ventral group and of 2,7° in the dorso-ventral group (p < 0,05). After 18 mo. Odom-score and subjective back function increased by 49% respectively 57% compared to the post-OP values (p< 0,05). Concerning the morbidity at the surgical approaches the pat. stated a pain relief of up to 73%.

Conclusions: Ms VTS with interposition of an autogenic bone graft of the iliac crest is an appropriate and meanwhile standardized minimal-invasive procedure with a low morbidity at the surgical approach. In this study a high potential for graft integration with a low amount of loss of correction could be detected in both groups (p < 0,05). For the mentioned indications the isolated ventral technique can be seen equal to the dorso-ventral procedure in 2 sessions. However the indication for an isolated ventral procedure has to be reconsidered carefully concerning increasing age and level of osteoporosis.

Endoscopic techniques lead to higher numbers of anterior procedures to the vertebral column. Navigation systems can assist to more precision using less x-rays. We registered prospectively more than 100 cases of anterior stabilization of the thoracic and lumbar spine using minimally invasive technique, endoscopic assistance and CT-based navigation. Patients were observed continuously over a time period of at least 12 month according to a standardized protocol.

135 patients were recorded prospectively between January 2002 September 2004. All patients recieved anterior procedures using endoscopical assistance. Operations were performed in prone position using Synframe® and navigation system by BrainLab®. The follow up of at least one year consisted in clinical investigations and radiographs 6 weeks, 3, 6, 9 and 12 months post OP.

87 male and 48 female patients were recorded with a mean age of 41 (16–77) years. 47 isolated anterior and 88 combined antero-posterior spondylodeses were performed with the described technique. In 101 cases thoracoscopy was used. For the instrumentation of L3, mini-lumbotomy was necessary which was also combined with Synframe® and endoscopical assistance. Isolated anterior procedures were completed under navigation control in 29 and combined antero-posterior procedures in 71 cases. Image intensifier times were reduced up to 85%, op-times were shortened using navigation for a mean of 22 minutes.

Navigation procedures showed initial learning curve. However, after this initial time it was a useful techique to enlarge precision and reduce op-times as well as x-ray exposition. The further standardization of the procedure lead to the development of advantageous instruments that further on will lead to even higher acceptance of this new technique.
