Complication rates after direct anterior vs posterior approach for hip hemiarthroplasty in elderly individuals with femoral neck fractures

BACKGROUND Dislocation rates after hemiarthroplasty reportedly vary from 1%to 17%.This serious complication is associated with increased morbidity and mortality rates.Approaches to this surgery are still debated,with no consensus regarding the superiority of any single approach.AIM To compare early postoperative complications after implementing the direct anterior and posterior approaches(PL)for hip hemiarthroplasty after femoral neck fractures.METHODS This is a comparative,retrospective,single-center cohort study conducted at a university hospital.Between March 2008 and December 2018,273 patients(a total of 280 hips)underwent bipolar hemiarthroplasties(n=280)for displaced femoral neck fractures using either the PL(n=171)or the minimally invasive direct anterior approach(DAA)(n=109).The choice of approach was related to the surgeons’practices;the implant types were similar and unrelated to the approach.Dislocation rates and other complications were reviewed after a minimum followup of 6 mo.RESULTS Both treatment groups had similarly aged patients(mean age:82 years),sex ratios,patient body mass indexes,and patient comorbidities.Surgical data(surgery delay time,operative time,and blood loss volume)did not differ significantly between the groups.The 30 d mortality rate was higher in the PL group(9.9%)than in the DAA group(3.7%),but the difference was not statistically significant(P=0.052).Among the one-month survivors,a significantly higher rate of dislocation was observed in the PL group(14/154;9.1%)than in the DAA group(0/105;0%)(P=0.002).Of the 14 patients with dislocation,8 underwent revision surgery for recurrent instability(posterior group),and one of them had 2 additional procedures due to a deep infection.The rate of other complications(e.g.,perioperative and early postoperative periprosthetic fractures and infection-related complications)did not differ significantly between the groups.CONCLUSION These findings suggest that the DAA to bipolar hemiarthroplasty for patients with femoral neck fractures is associated with a lower dislocation rate(<1%)than the PL.

Direct anterior compared to posterior approach for hip hemiarthroplasty following femoral neck fractures

The differences in complication rates between the direct anterior and posterior approaches for hemiarthroplasty in elderly patients with femoral neck fractures are not yet fully understood.Dislocation,a severe complication associated with increased mortality and often requiring additional surgery,may occur less frequently with the direct anterior approach compared to the posterior approach.Careful consideration of patient demographics is essential when planning the surgical approach.Future research in this area should focus on robust randomized controlled trials involving elderly patients recovering from femoral neck fractures.

Debate on direct-anterior vs posterior approach for hip hemiarthroplasty:The authors’insights

We read and discussed the study entitled“Complication rates after direct anterior vs posterior approach for Hip Hemiarthroplasty in elderly individuals with femoral neck fractures”with great interest.The authors have done justice to the topic of comparison of anterior and posterior surgical approaches for bipolar hemiarthroplasty which has been an everlasting debate in the existing literature.However,there are certain aspects of this study that need clarification from the authors.

Surgical resection of intradural extramedullary tumors in the atlantoaxial spine via a posterior approach

BACKGROUND The anatomical features of the atlantoaxial spine increase the difficulty of complete and safe removal of atlantoaxial intradural extramedullary(IDEM)tumors.Studies concerning surgical interventions via a posterior approach are limited.AIM To investigate the safety and efficacy of atlantoaxial IDEM tumor resection using a one-stage posterior approach.METHODS We retrospectively analyzed clinical databases for one-stage atlantoaxial IDEM tumor resection via a posterior approach between January 2008 and January 2018.The analyzed data included tumor position,histopathological type,pre-and postoperative Japanese Orthopedic Association(JOA)scores and Nurick grades,postoperative complication and recurrence status.RESULTS A total of 13 patients who underwent C1-C2 Laminectomy and/or unilateral facetectomy via the posterior approach were enrolled in the study.In all cases reviewed,total tumor resection and concomitant C1-C2 fusion were achieved.The average follow-up was 35.3±6.9 mo(range,26-49 mo).A statistically significant difference was noted between the preoperative JOA score(11.2±1.1)and the score at the last final follow-up(15.6±1.0)(P<0.05).A statistically significant difference was noted between the preoperative Nurick grade(2.3±0.9)and that at the last follow-up(1.2±0.4)(P<0.05).However,no statistically significant difference was noted between the preoperative and last follow-up C1-2 Cobb angle and C2-7 Cobb angle(P>0.05).No mortalities,severe complications or tumor recurrence were observed during the follow-up period.CONCLUSION Total resection of atlantoaxial IDEM tumors is feasible and effective via a posterior approach.Surgical reconstruction should be considered to avoid iatrogenic kyphosis and improve spinal stability and overall clinical outcomes.

Posterior approach (Kraske procedure) for surgical treatment of presacral tumors

Presacral tumors are rare,but can comprise a great variety of histological types.Congenital tumors are the most common.Once the diagnosis is established,surgical resection is essential because of the potential for malignancy or infection.Previous biopsy is not necessary or may be even harmful.To decide the best surgical approach(abdominal,sacral or combined) an individual and multidisciplinary analysis must be carried out.We report three cases of cystic presacral masses in which a posterior approach(Kraske procedure) enabled complete resection,the only way to decrease local recurrence.All patients had a satisfactory recovery.A brief overview of retrorectal tumors is presented,focusing on classification,clinical presentation,diagnosis and surgical management.

Assessment of the Outcome of Anterior versus Posterior Approach in the Management of Displaced Pediatric Supracondylar Humerus Fracture

Background: Supracondylar fractures of the humerus are among the most common type of pediatric fractures. The outcome of severely displaced supracondylar fracture of the humerus in children subjected to wide controversies in term of safety, functional and cosmetic outcome. Closed reduction and percutaneous pinning is now considered as the gold standard rule, but open reduction still applicable in certain cases where intraoperative imaging is not available, in comminuted lateral column fractures and uneducable fractures. Aim of the Study: To compare the outcome (functional and cosmetic) of anterior (Henry) approach with the posterior (Campbell) approach used in two groups of patients’ sustained displaced supracondylar fractures. Patients and Methods: This prospective study was performed on 48 pediatric patients who were been admitted to the Emergency Hospital in Sulaimani province sustained displaced supracondylar humeral fractures and treated during the period from the first of October 2009 to the thirty-one of January 2011. The study included 28 boys, 20 girls;their mean age was 7.5 years;their ages range 2 - 13 years. We used the modified Gartland classification to assess the fractures displacement and only Gartland type II B and III were included and managed operatively by open reduction and internal fixation with 2 crossed K-wires. Follow up continued for 6 months and the results finally assessed using Flynn’s criteria. Results: According to the criteria of Flynn et al., 20 patients (83.3%) treated by the anterior approach had excellent functional results while 4 patients (16.7%) had good functional results. While those treated by the posterior approach, 16 patients (66.6%) had excellent functional results, 6 patients (25%) had good results and 2 (8.3%) patients had fair outcome. Cosmetic results were excellent in 22 patients in the anterior approach group and 20 patients in the posterior approach group. Conclusion: Posterior Campbell approach is simpler than anterior Henry approach, but it creates additional soft tissue damage that can affect the circulatory status and hence possible osteonecrosis of the trochlea and a higher percentage of limitation in joint mobility. While the anterior approach is technically more demanding, but it gives better functional results.

Surgical treatment of cervicothoracic junction spinal tuberculosis via combined anterior and posterior approaches in children

Background Cervicothoracic junction spinal tuberculosis （CJST） in children is uncommon, especially when accompanied by a huge abscess. However, its consequences can be severe. Because of the special anatomic location of the cervicothoracic junction, surgical treatment is difficult and rarely reported. The aim of this clinical study was to assess the effectiveness of combined anterior and posterior approaches for focal debridement, decompression, allografting and anterior instrumentation in the treatment of CJST in children. Methods Ten pediatric CJST patients underwent focal debridement and cord decompression through combined anterior and posterior approaches. Then an appropriate allograft and titanium plate were applied to reconstruct the spine. The patients were asked to wear head-neck-chest braces for six months and received regular anti-tubercular drugs therapy for 12 months. Results The patients were followed-up for an average of 26 months （range, 15-32 months）. There was no recurrent tuberculous infection. The bone grafts incorporated well and the instrumentation was stable. Cervical and thoracic kyphosis was successfully corrected from 40° （range, 30-52°） before the operation to 18° （range, 12-26°） post-operation. Neurological function was improved in all patients. Conclusions Combined anterior and posterior approaches for focal debridement, decompression, bone allografting and anterior instrumentation provided an effective means of treatment in children of CJST with a huge abscess in the posterior part of the vertebral body.

Lower cervical spine injury treated with lateral mass plates and pedicle screws through posterior approach

Objective: To treat injury of the lower cervical spine C6 to C7 with cervical lateral mass plates and T1 pedicle screws through posterior approach. Methods: The data of 8 patients with lower cervical spine C6 or C7 injury （6 patients with fracture and dislocation in C6 and C7 and 2 with fracture in C7） were analyzed retrospectively in this study. For the preoperative American Spinal Injury Association （ASIA） classification, Grade C was found in 3 cases and Grade D in 5 cases. Screws were placed on the lateral masses and the first thoracic pedicle with Margerl technique. Lamina or facet bone allografting was used to achieve a long-term stability. Results: All the 8 patients were followed up for 5-37 months （mean: 15 months）. No operative death occurred. There were no examples of aggravation of spinal cord injury or vertebral artery injury, cerebrospinal fluid leak, nerve roots injury, screw malposition or back-out, loose of alignment or implant failure. Clinical symptoms and ASIA classification were improved in all the patients. Postoperative MRI scanning confirmed the satisfactory screw placement in all the cases. Conclusions: Lateral mass plates and pedicle screws through posterior approach are safe and beneficial for patients with lower cervical spine C6 or C7 injury.

Caudal approach to pure laparoscopic posterior sectionectomy under the laparoscopy-specific view

AIM:To study our novel caudal approach laparoscopic posterior-sectionectomy with parenchymal transection prior to mobilization under laparoscopy-specific view.METHODS:Points of the procedure are:(1) Patients are put in left lateral position and posterior sector is not mobilized;(2) Glissonian pedicle of the sector is encircled and clamped extra-hepatically and divided afterward during the transection;(3) Dissection of inferior vena cava(IVC) anterior wall behind the liver is started from caudal.Simultaneously,liver transection is performed to search right hepatic vein(RHV) from caudal;(4) Liver transection proceeds to the bifurcation of the vessels from caudal to cranial,exposing the surfaces of IVC and RHV.Since the remnant liver sinks down,the cutting surface is well-opend;and(5) After the completion of transection,dissection of the resected liver from retroperitoneum is easily performed using the gravity.This approach was performed for a 63 years old woman with liver metastasis close to RHV.RESULTS:RHV exposure is required for R0 resection of the lesion.Although the cutting plane is horizontal in supine position and the gravity obstructs the exposure in the small subphrenic space,the use of specific characteristics of laparoscopic hepatectomy,such as the good vision for the dorsal part of the liver and IVC and facilitated dissection using the gravity with the patient positioning,made the complete RHV exposure during the liver transection easy to perform.The operation time was 341 min and operative blood loss was 1356 mL.Her postoperative hospital stay was uneventfull and she is well without any signs of recurrences 14 mo after surgery.CONCLUSION:The new procedure is feasible and useful for the patients with tumors close to RHV and the need of the exposure of RHV.

Treatment of Posterior Malleolus Fracture through Posterolateral Approach

Posterior malleolus fractures are quite common and usually result from rotational ankle injuries. For the management of posterior malleolus fractures, more studies are still required, though it is already well-recognized for medial and lateral structure. Therefore, fracture of posterior malleolus is striking subject of study among orthopedic surgeons. Most orthopedic surgeons recommend fixing the posterior malleolus fracture if it is larger than 25% to 33% of the distal articular surface. Further attention is required for the reduction and fixation of fractures involving posterior malleolus. Several approaches and methods for fixation of posterior malleolus have been defined in the literature. Previously, the most common method of fixation of the posterior malleolus is by indirect reduction and antero-posterior screws, it is minimally invasive, the anterior incision does not allow satisfactory visualization of the fragment, so good anatomical reduction is difficult to achieve thorough this approach. Operative management goals to reach a stable ankle with maximal function, decrease the risk of post-traumatic degenerative changes, and diminish the risk of complication. Nowadays, posterolateral approach is gaining the popularity due to adequate visualization and accurate anatomic reduction.
