Purpose Nowadays, endoscopic techniques are widely used in surgical procedures. Retroperitoneoscopy has been an extremely valuable tool for a wide variety of urologic disorders, whereas, it has limited use in orthopedic procedures. MethodsWe performed retroperitoneoscopic drainage (in combination with medical treatment) of complicated psoas abscess on 12 patients with tuberculous spondylitis. All the procedures were done under general anesthesia and in the lateral decubitus position. Psoas abscess was evacuated during procedure, and postoperatively, drainage was continued through a large silastic tube. The definitive diagnosis and the treatment were made based on the results of culture-antibiogram and PCR testing. Results Complete clinical and radiologic remission was observed in all patients in 3-6 months. The complication was not observed in any case postoperatively.Conclusions Retroperitoneoscopic drainage of psoas abscesses gains advantages in terms of rapid recovery, minimal invasiveness, absence of radiation, and shorter hospital stay. This procedure can be used not only for cold abscesses but also for other pathologies of lumbar vertebral area.

Schwannomas are also known as neurolemmas that are usually originated from Schwann cells located in the peripheric nerve sheaths. They are the most common tumours of the hand (0.8–2%). They usually present solitary swelling along the course of the nerve however multiple lesions may be present in cases of NF type 1, familial neurofibromatosis, and sporadic schwannomatosis. Schwannomas are generally represented as an asymptomatic mass; however pain, numbness and fatigue may take place with the increasing size of the tumour. EMG (electromyelography), MRI (magnetic resonance imagination), and USG (ultrasound) are helpful in the diagnosis. Surgical removal is usually curative. In this paper, we present a 24-year-old male referred to our clinic for a lump located at the volar side of the left wrist and a lump located in his left palm and numbness at his 3rd and 4th fingers. Total excision was performed for both lesions. Histopathological examination of the masses revealed typical features of schwannoma. At the 6th-month followup the patient was symptom-free except for slight paresthesia of the 3rd and the 4th fingers. For our knowledge, this is the second case in the literature presenting wrist and palm involvement of the median nerve schwannoma.

Prospective comparative study, Level II.

Background: Both the ilioinguinal and Stoppa approaches have been used as standard methods for treating anterior column fractures of the pelvis. Objective: We aimed to compare the rigidity of pelvises that were treated using these two approaches. Methods: Fifteen synthetic pelvises were used as test models. Of these, 5 pelvises did not undergo any treatment (control group), and 10 pelvises underwent treatment of one column using the ilioinguinal approach and the other using the medial Stoppa approach (treated group). The compression test was performed on all pelvises, and rigidity of the pelvises was compared between the control and treated groups. Results: A statistical difference was found in the angle between the center of the femoral head and the line from the pubic symphysis to load application between the control and treated groups, using the ilioinguinal approach. The parametric displacement was greater in the treated group using the ilioinguinal approach than in the control group. There were no significant differences between the control and treated groups using the Stoppa approach, and the ilioinguinal approaches. Conclusion: Clinically, the Stoppa approach has several advantages over the ilioinguinal approach. However, based on the compression test, there was no difference in biomechanical rigidity between the fixations performed using these two approaches.

AIm:The sacral canal has been frequently used as "a passage" for minimally invasive diagnostic and therapeutic procedures for spinal diseases. The aim of the present study was to investigate morphometric analyses of the sacral canal, hiatus, and surrounding structures according to different age groups and gender by using the "multidetector computed tomography" method. mATeRIAL and meTHods: Multiplanar-reconstructed images from 300 adult (150 females and 150 males, between 20 and 80 years old) were divided into three groups according to age and retrospectively examined. Various anatomic measurements of the sacral hiatus, surrounding structures, and sacral canal were performed. Sacral curvature angle and lumbosacral lordotic angle were noted. ResuLTs:Bony anatomic abnormalities such as absent hiatus (0.3%), complete agenesis (1%), and bony septum (2.6%) were detected in some cases. The anteroposterior (AP) diameter of the hiatus was less than 2 mm in 5% of cases. In all groups, the mean values of the hiatus AP diameter and area, and the shortest distance of the sacral canal AP diameter were shorter in the 60-80 years age group when compared with those in 20-39 years age group (p=0.01). The shortest sacral canal AP diameter was commonly located at the S2 and S3 levels in 59.2% and 33.9% of cases, respectively. The levels of maximum curvature were at S3 and S2 in 63.3% and 26.7% of cases, respectively. Median sacral curvature angles and lumbosacral lordotic angles were measured as 164° and 134°, respectively. BuLGuLAR: Bazı olgularda hiatus yokluğu (%0,3), komplet agenezis (%1) ve kemik septum (%2,6) gibi kemik anomalilerine rastlandı. Anteroposterior (AP) Hiatus çapı olguların %5'sinde 2 mm nin altındaydı. Tüm yaş gruplarında, hiatus AP çapı ve hiatus alan ve "sakral kanal AP çapının en kısa mesafesinin" ortalaması, 60-80 yaş grubunda, 20-40 yaş grubuna göre daha kısaydı (p=0,01). Sakral kanal AP çapın en küçük olduğu lokalizasyon, en çok olguların %59,2'unda S2 ve %33,9'unda S3 seviyesinde idi. Maksimum kurvatür seviyesi olguların %63,3'ün de S3 ve %26,7'sin de S2 seviyesinde idi. Sakral kürvatur açı ve lumbosakral lordotik açı sırayla 164° and 134° olarak ölçüldü.soNuÇ: Sakral yapılarda anatomik varyasyonlar sık görünür. Anatominin ayrıntılı analizi, girişimsel işlemlerin başarısını ve güvenilirliğini artırabilir.
