Background: Over the past 10 years, 4 cases of spinal hydatid disease (3 men, 1 woman) were diagnosed and treated at our institution, with an average follow-up of 4 years. Hydatid disease of the spine is a rare condition with a poor prognosis that presents diagnostic and therapeutic challenges.Methods: The patients were evaluated clinically, using the latest imaging modalities available in our institution. Decompressive surgeries were performed and the diagnosis was confirmed by histopathologic examination. All patients received long-term antihelminthic therapy with 400 mg of albendazole 3 times daily for 1 year.Results: After surgery, all patients improved; however, over time, recurrence and residual disease were observed. Two patients had complete neurologic recovery at follow-up at 2 to 3 years, although there were radiographic signs of recurrence. The other 2 patients did not achieve complete neurologic recovery despite anterior decompression; they developed recurrent disease and the neurologic status deteriorated to spastic paraplegia. All patients refused further surgeries for recurrences and 2 patients died of complications of paraplegia. Conclusion:Diagnosis was challenging, eradication was difficult, and hydatid disease recurred in all 4 patients. In our experience, morbidity and mortality were high and prognosis was poor.

Objective:To assess the feasibility of retrograde ureteroscopic intrarenal surgery (RIRS) as a viable alternate to percutaneous nephrostolithotripsy (PCNL) in treating patients with renal and upper ureteric calculus of 1.6 cm to 3.5 cm stone burden.Materials and Methods:From October 2007 to November 2008, a total of 30 cases of upper ureteric and renal stone of 1.6 cm to 3.5 cm (Average size 2.5 cm) stone burden, for which PCNL would be done otherwise, were treated by RIRS with combined flexible and semi rigid ureteroscope and stones fragmented with holmium laser. The patients were discharged after 24 hours of the procedure and allowed to resume normal work after two days. X ray KUB for radio opaque stones and ultrasound for all the cases were done after three weeks and if any residual fragments of any size were present the patient was taken up for re-look flexible ureteroscopy under anesthesia. Stent and residual fragments were removed. If there was no residue the stent was removed under local anesthesia.Results:Complete clearance was considered if there were no fragments on USG screening after three weeks. Twenty six (86.6%) patients out of 30 had complete clearance in the first sitting and 4 (13.3%) patients needed re-look flexible ureteroscopy. The stone free rate in RIRS is 86.6% in the first sitting and 100% at second sitting.Conclusion:RIRS is superior in terms of less complication, less morbidity and good stone free rate and has an advantage of one day of hospital stay and resuming duties after two days. RIRS is the best option for managing extracorporeal shockwave lithotripsy failed and post PCNL residual calculus. RIRS is definitely a viable alternate for PCNL for upper tract stones up to 3.5 cm.

Background:Mucoid degeneration of the anterior cruciate ligament (ACL) is a less understood entity. The purpose of this study was to diagnose mucoid degeneration of anterior cruciate ligament and to assess the effectiveness of arthroscopic treatment in these patients.Materials and Methods:Between December 2007 and November 2011, 20 patients were diagnosed to be suffering from mucoid degeneration of anterior cruciate ligament (ACL) on the basis of magnetic resonance imaging (MRI), histopathology, and arthroscopy findings. 12 patients were males and 8 patients were females, with mean age of 42.2 years for males (range 28-52 years) and 39.4 years for females (range 30–54 years). They presented with pain on terminal extension (n=10) and on terminal flexion (n=2) without history of significant preceding trauma. MRI showed an increased signal in the substance of the ACL both in the T1- and T2-weighted images, with a mass-like configuration that was reported as a partial or complete tear of the ACL by the radiologist. At arthroscopy, the ACL was homogenous, bulbous, hypertrophied, and taut, occupying the entire intercondylar notch. A debulking of the ACL was performed by a judicious excision of the degenerated mucoid tissue, taking care to leave behind as much of the intact ACL as possible. Releasing it and performing a notchplasty treated impingement of the ACL to the roof and lateral wall. In one patient, we had to replace ACL due to insufficient tissue left behind to support the knee.Results:Good to excellent pain relief on terminal flexion–extension was obtained in 19 of 20 knees. The extension deficit was normalized in all knees. Lachman and anterior drawer test showed a firm endpoint in all, and 85% (n=17) showed good to excellent subjective satisfaction.Conclusions:Mucoid hypertrophy of the ACL should be suspected in elderly persons presenting pain on terminal extension or flexion without preceding trauma, especially when there is no associated meniscal lesion or ligamentous insufficiency. They respond well to a judicious arthroscopic release of the ACL with notchplasty.

Background Appropriate management of thoracolumbar injury with complete paraplegia remains controversial. Purpose of present study is to study whether advantages are worth the morbidity associated with staged anterior decompression in these patients. Materials and methods Forty patients (90% male) with fracture of T12 (32 cases) and L1 (8 cases) with complete paraplegia underwent transpedicular fixation. Average age of patients was 42 years (range 13-57 years). Most common fracture pattern was type A3.1 (55%). Rational staged anterior decompression was done in 20 cases. One group received transpedicular fixation (n = 20) and another fixation and staged decompression (n = 20). Average followup was 2.5 years. Results Mean functional independence measurement (FIM) score was 98 in fixation group and 112 in decompression group; mean neurological recovery as measured by American Spinal Injury Association (ASIA) grade was 1.3 and 1.75, respectively. Incidence of postoperative complications was 20% and 60%, respectively. Sphincter control did not recover in either group. Conclusions Rehabilitation is better after staged anterior decompression and fusion in burst fracture of thoracolumbar junction with complete paraplegia.
