Results of `Two Above- One Below Approach' with Intermediate Screws at the Fracture Site in the Surgical Treatment of Thoracolumbar Burst Fractures

The aim of this retrospective clinical study was to evaluate and compare the results of the technique so called ‘two above one below approach’ with intermediate screws at the fracture site with long-segment posterior fusion in the surgical treatment of thoracolumbar burst fractures. For this purpose neurologically intact 27 patients having isolated one level thoracolumbar burst fracture underwent posterior instrumentation and fusion in our clinic via ‘two above-one below approach’ with intermediate screws at the fracture site. A control group consisting of 15 patients having one level thoracolumbar burst fracture treated with long segment posterior spinal fusion in our institute was formed. At the preoperative, postoperative and final follow up period, anterior body height loss, local kyphosis and sagittal index values of both groups were noted. At the final follow up Visual Analogue Pain Scale and Oswestry disability scores were noted. Retrospective data from both groups underwent statistical analysis. In both groups anterior body height loss, local kyphosis and sagittal index measurements improved at the final follow-up, but there was no significance between two groups in terms of radiological and clinical follow-up data. The loss of correction in local kyphosis of short-segment group in the interval between postoperative and follow-up period was also significant. No implant failure was noted. As a conclusion 'two above one below approach’ with intermediate screws at the fracture site is associated with loss of correction radiographically, but favorable clinical outcomes in the presence of any implant failure can be achieved in the treatment of thoracolumbar burst fractures

Unilateral Carpal Tunnel Syndrome Caused by an Occult Ganglion in the Carpal Tunnel: A Report of Two Cases

Carpal tunnel syndrome (CTS) usually presents bilaterally and a secondary nature should be suspected in patients with unilateral symptoms, especially those with a long-standing history, and when the symptomatic hand shows severe neurophysiologic impairment, while the contralateral hand is neurophysiologically intact. Space-occupying lesions are known to cause CTS and the incidence of space-occupying lesions in unilateral CTS is higher than that of bilateral CTS. It is easy to detect a mass when it is palpable; however, occult lesions are usually overlooked. Whenever a patient presents with unilateral symptoms and unilateral neurophysiologic impairment, the possibility of a space-occupying lesion compressing the median nerve should be kept in mind in the differential diagnosis. This study presents two cases with an occult ganglion in the carpal tunnel compressing the median nerve and causing unilateral symptoms of CTS. We stress on the importance of imaging studies in patients with unilateral symptoms that are usually not used in CTS. The reported patients were evaluated and magnetic resonance images revealed an intratunnel space-occupying lesion

Atypically localized glomus tumor causing anterior interosseous nerve syndrome: A case report

This article presents a 48-year-old male patient who presented with pain in the left forearm and weakness and clumsiness in the left hand of 6 months' duration. Flexor motor strength loss of the thumb and the index finger was present and neurophysiologic tests showed findings compatible with axonal injury in the anterior interosseous nerve (AIN) innervated muscles. Magnetic resonance imaging revealed a space-occupying lesion in the proximal forearm resembling a glomus tumor. Excision of the mass and release of the AIN were performed. Histopathology confirmed a glomus tumor, and the patient remains asymptomatic at 1 year postoperatively. We stress the importance of imaging studies in patients when a suspected secondary nature of nerve entrapment is present. Keywords: Glomus tumor, Anterior interosseous nerve syndrom

Effect of PEEK Polymer on Tunnel Widening After Hamstring ACL Reconstruction

The purpose of this study was to evaluate the effect of the AperFix device (Cayenne Medical, Inc, Scottsdale, Arizona), composed of polyetheretherketone (PEEK) polymer, on tunnel widening after hamstring anterior cruciate ligament (ACL) reconstruction as compared with 2 other fixation devices: the TransFix (Arthrex, Inc, Naples, Florida) and the EndoButton (Smith & Nephew Endoscopy, Mansfield, Massachusetts). Sixty-seven patients with isolated total ACL ruptures who underwent arthroscopically assisted reconstruction using hamstring autografts at the authors' institution were included in the study. Patients were assigned into 1 of 3 groups in a nonrandomized fashion: AperFix (n=18), TransFix (n=29), and EndoButton (n=20). Mean follow-up was 30 months. Tunnel widening measurements were performed on anteroposterior and lateral digital plain radiographs taken in postoperative week 1 and at final follow-up. Laxity testing, Lysholm scoring, and arthrometric evaluation were performed
