Gastrocnemius raphe split approach for complex proximal tibia fractures—Applicability and advantages

Posterior column fractures of the tibial plateau have been considered problem injury as many authors reported poor outcome. Commonly used surgical approaches have limitations in addressing complex fractures involving the posterior column, leading to malreduction and subsequent leading to chronic posteroinferior subluxation, arthritis and chronic pain. There is thus a need for a surgical approach, which can provide adequate exposure to both quadrant of posterior column, in addition to allowing sufficient space for fracture manipulation and implant placement. The authors have evaluated the applicability of the posterior midline gastrocnemius raphe split approach to deal with coomplex posterior column fragment in tibial plateau fractures.A midline gastrocnemius splitting approach was used alone or along with other approaches in 22 patients with tibial plateau fractures involving the posterior column. The mean age of the patients was 36 years and the female to male ratio was 1:6 (3 and 18). At an average follow up of 12 months (Range 6–14 months), Radiological evidence of union was noted at an average 13 weeks (Range, 10-15weeks) and no loss of reduction was seen at follow-up. All cases had regained painless knee flexion that averaged 120°.The midline gastrocnemius splitting approach is a versatile approach, which allows adequate exposure on either side of the posterior tibial plateau. This can easily combined with other approaches, where the anteromedial and anterolateral coloumn or associated ligament injury demand attention.

The Stoppa approach for acetabular fracture

Objective

Acetabular fractures pose a great surgical challenge for orthopedic trauma surgeons. We believe that the Stoppa approach with an iliac window extension, previously described as a modified Stoppa approach is adequate for the majority of acetabular fractures excluding those with predominant posterior wall involvement. In this paper we will present our experience in using the Stoppa approach, its indications, preparations, the detailed surgical approach, complications and the different tips used in this relatively modern approach.

Indications

All simple and combined fracture types that involve the anterior column of the pelvis including the quadrilateral plate.

Contraindications

Posterior wall or extensive posterior column involvement. Transverse and T-fractures with mainly posterior displacement.

Surgical technique

Suprapubic, intrapelvic approach, extending from the symphysis pubis anteriorly to the sacroiliac joint posteriorly. Superficial landmarks are identical to the Pfannenstiel approach, the rectus abdominis muscles are longitudinally dissected, the symphysis pubis is exposed and a sub-periosteal deep surgical dissection is carried out along the anterior column and the quadrilateral plate, and posteriorly toward the greater sciatic notch and the sacroiliac joint.

Results

In a 5-year review of 60 acetabular fractures that underwent open reduction and internal fixation using the modified Stoppa approach, there were 36% anterior column fractures, 28% both-column fractures, the rest being anterior column with posterior hemi transverse fractures, transverse and T-fractures. Any extension of the fracture to the iliac wing necessitated an additional lateral window (93% of cases). In cases with posterior displacement, an additional approach was utilized to address a posterior wall fracture. All fractures healed within 12?weeks. Mean Merle d’Aubigné score was 15.22. Postoperative radiological evaluation revealed anatomical reduction in 54% of the patients, satisfactory in 43%, and unsatisfactory in 3% of the patients. Overall there were 15?minor and major complications

Use of kyphoplasty versus 360-degree fusion for unstable thoracolumbar burst fractures: Using minimally invasive techniques in trauma

Much controversy surrounds the treatment of unstable thoracolumbar burst fractures with treatment options consisting of anterior, posterior, or combined anterior and posterior surgery. Traditionally, anterior column reconstruction has been performed through an anterior approach with vertebrectomy and reconstruction with a cage or structural graft. This is typically supplemented with posterior pedicle screw fixation. There has been increased interest in pursuing minimally invasive options to decrease patient morbidity. The article discusses the use of vertebroplasty to support the anterior column and discusses the risks, benefits, biomechanics, and outcomes of such a procedure in the treatment of thoracolumbar burst fractures.     

Single-stage posterolateral transpedicle approach for spondylectomy, epidural decompression, and circumferential fusion of spinal metastases

STUDY DESIGN: Retrospective review of prospectively maintained institutional spine database. OBJECTIVES: To assess the pain, neurologic, and functional outcome of patients with metastatic spinal cord compression using a posterolateral transpedicular approach with circumferential fusion. SUMMARY OF BACKGROUND DATA: Patients with spinal metastases often have patterns of disease requiring both an anterior and posterior surgical decompression and spinal fusion. For patients whose concurrent illness or previous surgery makes an anterior approach difficult, a posterior transpedicular approach was used to resect the involved vertebral bodies, posterior elements, and epidural tumor. This approach provides exposure sufficient to decompress and instrument the anterior and posterior columns. METHODS: During the past 15 months, 25 patients were operated on using a posterolateral transpedicular approach. The primary indications for surgery were back pain (15 patients) and neurologic progression (10 patients). All patients had vertebral body disease, and 21 patients had high-grade spinal cord compression from epidural disease as assessed by magnetic resonance imaging. Seven patients underwent preoperative embolization for vascular tumors. In each patient, the anterior column was reconstructed with polymethyl methacrylate and Steinmann pins and the posterior column with long segmental fixation. RESULTS: All patients achieved immediate stability. Pain relief was significant in all 23 patients who had had moderate or severe pain. Neurologic symptoms were stable or improved in 23 patients. One patient with an acutely evolving myelopathy was immediately worse after surgery, and one patient had a delayed neurologic worsening, progressing to paraplegia. CONCLUSIONS: The posterolateral transpedicular approach provides a wide surgical exposure to decompress and instrument the anterior and posterior spine. This technique avoids the morbidity associated with anterior approaches and provides immediate stability. Vascular tumors may be removed safely after embolization. Patients can be mobilized early after surgery.     

Cefuroxime concentrations in the anterior and posterior column of the lumbar spine – an experimental porcine study

BACKGROUND CONTEXTSurgical site infection following spine surgery is associated with increased morbidity and mortality. Perioperative antibiotic prophylaxis is a key factor in lowering the risk of acquiring an infection. Previous studies have assessed perioperative cefuroxime concentrations in the anterior column of the cervical spine with an anterior surgical approach. However, the majority of surgeries are performed in the posterior column and many surgeries involve the lumbar spine.PURPOSEThe objective of this study was to compare the perioperative tissue concentrations of cefuroxime in the anterior and posterior column during lumbar spine surgery with a posterior surgical approach.STUDY DESIGNIn vivo experimental pharmacokinetic study of cefuroxime concentrations in an acute preclinical porcine model.METHODSThe lumbar vertebral column was exposed from L1 to L5 in 8 female pigs. Microdialysis catheters were placed for sampling in the anterior column (vertebral body) and posterior column (posterior arch) within the same vertebra (L5). Cefuroxime (1.5 g) was administered intravenously. Microdialysates and plasma samples were continuously obtained over 8 hours. Cefuroxime concentrations were quantified by Ultra High Performance Liquid Chromatography Tandem Mass Spectrometry. The primary endpoint was the time above the cefuroxime clinical breakpoint minimal inhibitory concentration (T>MIC) for Staphylococcus aureus of 4 µg/mL. The secondary endpoint was tissue penetration (AUC_tissue/AUC_plasma).RESULTSMean T>MIC 4 µg/mL (95% confidence interval) was 123 min (105–141) in plasma, 97 min (79–115) in the anterior column and 93 min (75–111) in the posterior column. Tissue penetration (95% confidence interval) was incomplete for both the anterior column 0.48 (0.40–0.56) and posterior column 0.40 (0.33–0.48).CONCLUSIONST>MIC was comparable between the anterior and posterior column. Mean cefuroxime concentrations decreased below the clinical breakpoint minimal inhibitory concentration for S. aureus of 4 µg/mL after 123 minutes (plasma), 97 minutes (anterior column) and 93 minutes (posterior column). This is shorter than the duration of most lumbar spine surgeries, and therefore alternative dosing regimens should be considered in posterior open lumbar spine surgeries lasting more than 1.5 hours.CLINICAL SIGNIFICANCEOpen lumbar spine surgery often involves extensive soft tissue dissection, stripping and retraction of the paraspinal muscles which may impair the local blood flow exposing the lumbar vertebra to postoperative infections. A single intravenous administration of 1.5 g cefuroxime only provided sufficient prophylactic target tissue concentrations in the vertebra of the lumbar spine for up to 1.5 hours.

The extended posterolateral approach for split depression lateral tibial plateau fractures extending into the posterior column: 2 years follow up results of a prospective study

ObjectiveTo prospectively study the outcome of surgically treated split depression lateral tibial plateau fractures extending into the posterior column using the extended posterolateral approach.MethodsTwenty-one patients with split depression lateral tibial plateau fractures (AO: 41-B3) with extension into the posterior column were treated with open reduction and internal fixation through an extended posterolateral approach with osteotomy of the fibular neck ± Gerdy tubercle. Follow up radiographs was assessed for quality of articular reduction and limb axis. Functional assessment was performed at last follow up using the Tegner–Lysholm score. Complications pertaining to the surgical approach were recorded.ResultsThe approach was performed in 15 patients with a fibular neck osteotomy alone and 6 patients required a Gerdy's tubercle osteotomy also. All fractures and osteotomies had united. Anatomical articular reduction was achieved in 16 patients. Radiological limb alignment was restored in all patients except for a reversed posterior slope in 1 patient. Arthritic changes were seen in 3 patients. The mean Tegner–Lysholm score was 87.3 (range: 76–95) at last follow up. No specific complications related to the surgical approach like common peroneal nerve injury and lateral instability of the knee was encountered.ConclusionThe extended posterolateral approach offers excellent exposure posterior to the fibular head to perform articular reduction and fixation achieving satisfactory radiological and functional results in split depression lateral tibial plateau fractures extending into the posterior column.     

Posterior midline approach for single-stage en bloc resection and circumferential spinal stabilization for locally advanced Pancoast tumors. Technical note

The treatment of Pancoast (superior sulcus) tumors that extensively invade the vertebral column remains controversial. Different surgical approaches involving multistage resection techniques have been previously described for superior sulcus tumors that invade the chest wall and spinal column. Typically a posterior approach to stabilize the spine is followed by a second-stage thoracotomy (posterolateral or trap door) for definitive en bloc resection of stage T4 Pancoast tumors. The authors report and elaborate on a surgical technique successfully used for an en bloc resection as well as spinal stabilization through a single-stage posterior approach without any added morbidity. Two patients with histologically proven Pancoast tumors were treated by single-stage resection and stabilization through a posterior approach at the H. Lee Moffitt Cancer Center. A wedge lung resection or lobectomy was performed by the chest surgeon utilizing the chest wall defect. Placement of an anterior cage (in one case) and posterior cervicothoracic spinal instrumentation (in both cases) was performed during the same operation. Average blood loss was 675 ml and surgical time was 7 hours. The median hospital stay was 9 days (range 7-11 days). Both patients did well postoperatively and were free of recurrence at the 2-year follow-up. Radical resection of Pancoast tumors including lobectomy, chest wall resection, costotransversectomy, and partial or complete vertebrectomy with simultaneous instrumentation for spinal stabilization can be performed through a posterior single-stage approach.
