Delayed presentation of Wilkie's syndrome after scoliotic curve correction surgery: a case report.

BACKGROUND: Superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, is a rare but serious complication following scoliosis correction surgery. It occurs as a result of mechanical compression of third part of duodenum between the SMA and aorta. This condition occurs most commonly in significantly underweight patients with deformities, and usually during the first week following spinal deformity corrective surgeries. The angle between the abdominal aorta and the SMA gets reduced following spinal lengthening during deformity correction surgery causing compression of third part of duodenum resulting in development of SMA syndrome. CASE PRESENTATION: We present a case of 17-year-old male with congenital scoliosis with a 70-degree scoliotic curve who underwent spinal deformity correction surgery with posterior instrumented fusion. Post-operative course was uneventful and the patient was discharged after suture removal on post-operative day 15. The patient presented after 21-days of symptom onset on post-operative-day 51, with a 3 week history of post-prandial vomiting, abdominal pain and distension which resulted in rapid weight loss of 11 kg. A CT-angiogram showed obstruction at third part of duodenum. After reviewing clinical and radiological profile of the patient, a diagnosis of SMA syndrome was made. Conservative management was tried, but due to rapid deterioration of patient condition and symptoms of complete intestinal obstruction, the patient was treated surgically by gastro-jejunostomy and side-to-side jejuno-jejunostomy, which improved his condition. CONCLUSION: SMA syndrome can occur much later than previously reported cases and with potentially life-threatening symptoms following scoliosis correction. Having a high index of suspicion, early recognition of condition and institution of appropriate treatment are essential to prevent occurrence of severe complications including risk of intestinal perforation and mortality. This case highlights management of delayed onset of SMA syndrome, with presentation further delayed after symptom onset, as is common in developing parts of the world, due to limited availability and accessibility of resources, and low socio-economic status of large segments of the population.

Impairments in pulmonary functions in paediatric spinal tuberculosis: a cross-sectional study.

PURPOSE: This study aimed to investigate the impact of vertebral column destruction and kyphotic deformity due to spinal tuberculosis on pulmonary functions in paediatric patients. METHODS: A cross-sectional study was conducted, involving 30 patients diagnosed with healed spinal tuberculosis, aged 7-18 years. Detailed radiographic measurements, including the level of involvement, kyphosis angle, Spinal Deformity Index (SDI), and drug-resistance status, were compared with various pulmonary function parameters. RESULTS: The mean age of the study group was 12.8 ± 2.7 years (range 7-17 years), consisting of 11 males and 19 females. Fourteen patients were managed conservatively and 16 were managed operatively. The mean SDI was 5.2 ± 4.7. The mean kyphotic angle was 31.3° ± 25.3. The average number of involved vertebrae was 2.6 ± 1.5. Pulmonary functions were classified as restrictive in 24 patients, normal in 4 patients, obstructive in 1 patient, and mixed in 1 patient. Multidrug-resistant tuberculosis (MDR-TB) was detected in 5 (16.7%) patients, while the remaining 25 (83.3%) patients were sensitive to conventional antitubercular drugs. The correlation coefficients between the percentage reduction in forced vital capacity (FVC) and kyphosis angle, SDI, and number of vertebrae were 0.4 (p = 0.026), 0.4 (p = 0.028), and 0.19 (p = 0.295), respectively. The mean percentage reduction in FVC and total lung capacity (TLC) were 35.8 ± 15.7 and 6.2 ± 2.3, respectively. No significant association was observed between pulmonary functions and drug sensitivity status (p = 0.074). CONCLUSIONS: Paediatric spinal tuberculosis can lead to thoracic insufficiency due to progressive destruction and shortening of the spinal column, spinal growth inhibition, and kyphotic deformity. Management of these cases should focus on promoting normal lung development while ensuring disease resolution and deformity correction. Further research should explore growth conserving or growth guiding systems to address or prevent growth retardation and simultaneously provide spinal stabilization.

Functional and radiological outcomes following craniovertebral junction surgery.

Background: Craniovertebral junction (CVJ) pathologies include atlantoaxial instability/deformities resulting in myelopathy, respiratory failure, and even death. Here, we describe the indications, preoperative planning, and intra-operative/postoperative complications following surgical management of CVJ anomalies. Methods: A prospective analysis of 34 patients with CVJ pathology was evaluated between 2015 and 2022. Their various etiologies included atlantoaxial instability, trauma, tuberculosis, Down's syndrome, Morquio syndrome, os odontoideum, and atlantoaxial abnormalities. Clinical outcomes were assessed using the American spinal injury association (ASIA) impairment scale score and Benzel's modified Japanese Orthopedic Association (mJOA) score. Surgical assessments included length of hospital stay, operative time, blood loss, and intraoperative postoperative complications. Radiological parameters included fusion (i.e., implant loosening/implant failure), preoperative/ postoperative atlanto-dens interval (ADI), clivus canal angle (CCA), and space available for cord (SAC). Results: Five patients were managed conservatively, while 29 patients had surgery. Operations included occipitocervical fusion (14 patients), C1-2 fusion (10 patients), C1-2 transarticular screw fixation (four patients), and one patient underwent anterior corpectomy decompression/fusion. Seven patients had vertebral artery anomalies, and 13 patients had atlantoaxial abnormalities. At the final follow-up, atlantoaxial instability (i.e., mean preoperative ADI of 6.6 ± 2.3 mm) was restored to 4.2 ± 0.6 mm, significant cord compression (i.e., with mean SAC of 8.3 ± 2.9 mm) was relieved to 17.2 ± 1.6 mm, and the mean preoperative CCA (i.e., 130.2 ± 15.3) was improved to 143.3 ± 8.3°. There was also a statistically significant improvement in the ASIA scale and mJOA score. Conclusion: Surgical management of CVJ abnormalities requires expertise and meticulous planning to avoid devastating complications such as wound dehiscence and catastrophic vertebral artery injury.

A novel technique of managing an irreducible posteriorly displaced type 2 odontoid fracture: A case report.

Background: Type 2 odontoid fractures with posterior displacement are rare. Most acute cases reported in the literature are readily reduced with traction alone. Here, we reviewed the management of a chronic, posteriorly displaced odontoid fracture that was managed with a unique posterior reduction maneuver. Case Description: A 58-year-old male with a chronic type 2 retro-odontoid displaced fracture was managed with traction and an anterior force applied to the displaced odontoid fragment using rods attached to bilateral C1 lateral mass screws. Notably, this included a simultaneous cantilever maneuver using a lever placed between the C1 and C2 facet joints. Following reduction, an atlantoaxial fusion was performed. The postoperative course of the patient was uneventful and the bone union was achieved in 1 year. Conclusion: Closed reduction is rarely successful in chronic posteriorly displaced type 2 odontoid fractures. These cases require meticulous open reduction and fixation.

Tibial lengthening for massive distal femoral bone loss.

A man in his 30s was involved in a road traffic accident (RTA) and sustained a grade-IIIA distal femur fracture with acute loss of distal two-third of the femur. Initially, damage control surgery was done by an external fixator application. Later, staged limb reconstruction surgery was undertaken as a definitive procedure that involved bifocal distraction osteogenesis involving the proximal tibia and femur along with docking of the corticotomised femoral fragment onto the tibial plateau to achieve knee arthrodesis. The tibial and femoral regenerate together measured 25.8 cm at the end of distraction phase leaving behind a limb length discrepancy of 5 cm. Acute traumatic large bone loss is a rare presentation and is beset with unique management challenges. Limb reconstruction surgery (LRS) with LRS system provides flexibility to tackle individual case-based scenarios and helps achieve limb length, maintain alignment and restore function.

Efficacy of Periarticular Local Infiltrative Analgesic Injection on Postoperative Pain Control and Functional Outcome in Sequential Bilateral Total Knee Replacement: A Prospective Controlled Trial in 120 Consecutive Patients.

Background: One of the drawbacks of total knee replacements (TKR) is the early postoperative pain, which affects patient satisfaction and increases the duration of rehabilitation. The present study analyzes the potency of local infiltrative analgesia and its effect on rehabilitation in bilateral sequential TKRs. Materials and Methods: The present prospective observational study was conducted on 120 patients undergoing bilateral sequential TKR performed by a single surgeon using an anterior midline incision with a standard medial parapatellar approach. At the end of the surgery, a periarticular cocktail injection was administered to one knee, whereas the other knee served as the control. Postoperatively, patients were assessed for the pain level in each knee based on the visual analog scale (VAS) score and improvement in the range of motion (ROM). Intergroup and intragroup analyses were performed using the unpaired t test and analysis of variance, respectively. A p value of < 0.05 was considered significant. Results: Of the 120 patients, 58% were women and 42% were men with a mean age of 62.14 ± 8.58 years. The postoperative mean VAS score was significantly lower in the test knee group than in the control knee group (p < 0.05). The postoperative mean ROM was more in the test group as compared to the control group on days 3 and 7 (p < 0.05), whereas it was comparable on day 14 (p > 0.05). Conclusion: Periarticular injection of a drug combination in patients managed with bilateral TKRs that are done simultaneously reduces the early postoperative pain and improves rehabilitation during the first week after surgery.

Degenerative Cervical Spondylosis: A Cause of Vertigo?

STUDY DESIGN: Prospective observational study. OBJECTIVES: Studying the effect of degenerative cervical spondylosis(CS) on blood flow velocity of vertebral artery (VA) during cervical spine rotation in different head positions and its association with vertigo. INTRODUCTION: Vertigo is one of the most common complaints seen in an out-patient clinic. Its association with CS remains an enigma for a treating physician. This study planned to systematically analyze the association between vertigo and CS by evaluating VA blood flow dynamics in different head positions. METHODS: 100 patients with ages ranging from 20-80 years were recruited. First group of 50 patients with CS with vertigo were compared with second study group of 50 patients having CS without vertigo. Cervical radiographs were used to evaluate CS using cervical degenerative index (CDI). Color doppler was used to measure VA blood flow with head in neutral position and 60° lateral rotation with 30° extension. Same procedure was repeated on opposite side. Measurements performed included peak systolic blood flow velocity(PSV) and end diastolic blood flow velocity (EDV). RESULTS: Among patients with CS, patients having vertigo showed significantly more evident degenerative changes (CDI ≥25) (P=<0.001). High grade CS patients (CDI ≥25) with vertigo had statistically significant lower blood flow parameters with head rotation in the left and right VAs as compared to CS patients without vertigo. CONCLUSION: This study highlights important pathophysiological mechanism of vertigo observed in patients of CS. The magnitude of reduction in VA blood flow was significantly higher in patients with advanced CS presenting as vertigo.

Outcome of Joint Aspiration in Acute Knee Haemarthrosis in a Haemophilic Joint: A Prospective Randomised Controlled Trial in 120 Patients in a Tertiary Haemophilia Care Centre.

Background: Bleeding into the joints cause major morbidity in haemophilia patients. The clinical hallmark of haemophilia is haemarthrosis especially in knee, ankle and elbow joint. Current literature suggests that aspiration of an acute haemarthrosis in haemophilia may lead to further bleeding and prevent tamponade effect. But the rehabilitation gets delayed, leading to joint stiffness and the function gets deteriorated. This study was done to evaluate the efficacy of joint aspiration in the management of acute knee haemarthrosis, with regard to pain relief and functional outcome. Materials and Methods: This is a prospective, randomised controlled trial in a tertiary care haemophilia treatment centre comprising 120 haemophilic patients with unilateral acute knee haemarthrosis. Factor level was checked and appropriate factor replacement [40%] was done. The patients were randomly allocated in two groups: Group A and Group B, each consisting of 60 patients. All patients received ice application, limb immobilisation, analgesics, physiotherapy and compression bandage as the routine primary management. In addition, study Group A also received therapeutic aspiration of the knee joint at initial presentation, after the first factor infusion. All patients were clinically evaluated for pain in terms of Visual Analogue Scale (VAS score) and function in terms of Haemophilic Joint Health Score [HJHS], before and at 4 h, 48 h and 7 days after initial factor administration. Results: All patients showed therapeutic improvement in terms of a declining trend in VAS and HJHS scores. Pain relief (VAS Score) in Group A, was found to be significantly better compared to Group B at the end of 4 h [4.80 ± 0.49 vs 6.54 ± 1.05; p < 0.001], 48 h [2.48 ± 0.50 vs 3.30 ± 0.46; p < 0.001] and 7 days [1.16 ± 0.37 vs 1.70 ± 0.46; p < 0.001]. Functional improvement (HJHS Score) in Group A, was found to be significantly better compared to Group B as well at the end of 4 h [11.24 ± 0.77 vs 14.52 ± 0.61; p < 0.001], 48 h [7.24 ± 0.65 vs 11.28 ± 0.64; p < 0.001] and 7 days [2.36 ± 0.48 vs 5.52 ± 0.67; p < 0.001]. Conclusion: Our study recommends the use of joint aspiration as a therapeutic tool in the holistic management of acute knee haemarthrosis in addition to usual treatment of ice application, immobilization and oral tranexamic acid. Early factor replacement along with therapeutic joint aspiration is a key for better pain relief and a better functional outcome.

The influence of joint line restoration on functional outcome after primary total knee arthroplasty: A prospective study.

Objective: Restoration of proper joint line position after primary total knee arthroplasty (TKA) is important for improved knee function and kinematics. We reviewed the magnitude of joint line alteration and the resulting effect on post-operative knee outcomes scores at one year follow-up. Materials and methods: 120 patients who underwent TKA for primary osteoarthritis knee were included. Assessment of joint line position before and after surgery was performed with the help of bony landmarks (excluding osteophytes): Medial Epicondyle Joint Line distance (MEJL), Lateral Epicondyle Joint Line distance (LEJL) and Fibula Head Joint Line distance (FHJL) were calculated. Post-operative knee function was assessed using 'The Western Ontario and McMaster Universities Arthritis Index' (WOMAC) and 'Knee Society Score' (KSS) at one year follow-up. Results: Joint line elevation was observed in 104/120 (86.7%) patients and 16/120 (13.3%) patients had no joint line elevation. The mean joint line elevation was 3.00 (±2.13) mm. The patients were sub-classified into two study groups: Group A- Joint line elevation <5 mm and Group B- Joint line elevation ≥ 5 mm. The mean post-op one-year KSS score was significantly higher in patients in Group A compared to Group B (52.82 ± 7.564 vs. 40.73 ± 7.146; p < 0.001). The mean post-op one-year WOMAC score was lower in patients in Group A compared to Group B (65.51 ± 14.762 vs.75.64 ± 8.203) and the difference was statistically significant (p = 0.002). Conclusion: Elevation of joint line ≥5 mm from the pre-operative value has a negative impact on post-operative functional outcome in primary TKA.

Proximal Thoracic Kyphoscoliosis with Dorsal Myelopathy in a Case of Congenital Absence of Thoracic Pedicles: A Case Report.

CASE: A 14-year-old boy with proximal thoracic kyphoscoliosis associated with the bilateral absence of thoracic pedicles presented with progressive deformity, paraparesis, and difficulty in ambulation. The case was managed by preoperative halo traction, single-stage 2-level vertebral column resection, decompression, and arthrodesis of thoracic vertebrae. Two years postoperatively, the patient showed neurological improvement, leading to unassisted ambulation and fusion at the corpectomy site. CONCLUSION: Preoperative halo-gravity traction restores the sagittal and coronal balance, improves the functional status of the patient, and corrects the deformity to some extent. 3D printed models help in better understanding of osseous anatomy and minimizing intraoperative time.

Functional outcomes in the management of cervicothoracic junction tuberculosis.

Background: We analyzed the clinical and radiological parameters influencing functional outcomes and neurological recovery in patients with cervicothoracic junctional tuberculosis (TB). Methods: This was a retrospective analysis of 16 cases of cervicothoracic junction (CTJ) spinal TB; 11 patients were managed operatively, while five were managed conservatively. Patients' outcomes were assessed at 1 month, 1 year, and yearly thereafter and included an analysis of multiple outcome scores, various radiographic parameters, and sensitivity or resistance to anti-tubercular therapy. Results: Patients averaged 25.94 years of age, and typically had three-level vertebral involvement. They were followed for a mean duration of 24 months, and the duration of anti-tubercular therapy averaged 17 months. Patients demonstrated clinical improvement on Japanese Orthopedic Association score and Neck disability index (P < 0.005) starting from 1 month following initiation of treatment which continued in subsequent follow-up, along with change in radiological parameters consisting of mean segmental kyphotic angle from 18.98° to 15.13°, C2-C7 SVA from 16.13 mm to 22.61 mm, T1 slope from 22.80° to 14.66°, thoracic inlet angle from 75.35° to 63.25°, neck tilt from 51.81° to 48.33°, and cervical lordosis from 4.66° to -0.44° (P > 0.05) at the end of 1 year. Conclusion: Tuberculous affection of the dynamic CTJ is a challenging scenario in clinical practice and its management involves consideration of disease extent, neurological status, and effort toward restoration of normal alignment of spine in sagittal and coronal plane to get favorable clinical outcomes.

A case of cervical OPLL and DISH mimicking stroke.

Background: Ossification of the posterior longitudinal ligament (OPLL) is a progressive disorder that mostly involves the cervical spine. It is more prevalent in East Asian countries. Patients typically present with the gradual onset of myelopathy, while about 5% show rapid progression. Case Description: A 51-year-old diabetic and hypertensive male presented with a left-sided hemiparesis following trivial trauma. The first diagnosis was a stroke, but the subsequent workup proved negative. Subsequently, the MRI and CT studies demonstrated significant cord compression due to OPLL extending from C2 to C7. There was also a heterogeneous hyperintense intramedullary cord signal indicative of edema/myelomalacia in the retro- odontoid region. The CT also diagnosed C2-C7 diffuse idiopathic skeletal hyperostosis. Conclusion: Patients with cervical myelopathy due to OPLL rarely present about 5% of the time with the acute onset of neurological deficit following minor trauma. Certainly, one must consider high cervical OPLL as responsible for hemiparesis in a patient whose brain MR has ruled out a stroke.

Clinicoradiological outcome of percutaneous intralesional polidocanol in Aneurysmal Bone Cysts: A prospective study of 43 patients in a single tertiary care centre.

Objective: The study reports the efficacy of sequential instillations of intralesional percutaneous polidocanol in the treatment of skeletal ABC. The study also analyses the pain relief, recurrence, radiological outcome and complications after percutaneous sclerotherapy. Materials and methods: A total of 43 patients with ABC were managed by fluoroscopy assisted percutaneous intralesional sclerotherapy with 3% Injection Polidocanol under suitable anaesthesia. The pain relief was assessed by Visual Analog Scale (VAS) and the progressive healing of the lesion by Rastogi Classification. Patients were evaluated clinico-radiologically, pre-operatively and at monthly interval for the first three months and then at 6 months, one year and two years follow up. Result: The VAS score decreased significantly at six months follow up and was zero (No pain) at one year follow up. Out of 43 patients, 37 patients had Degree I (excellent) residual lesion and 6 patients had degree II (good) lesion at one year follow-up as per Rastogi classification. The lesions resolved completely by two-year follow-up with all 43 patients having Degree (excellent) I resolution. Conclusion: Our study highlights the efficacy of percutaneous intralesional polidocanol in the treatment of ABC's. The procedure is safe, simple and effective with excellent outcome. Sclerotherapy is highly beneficial for deep lesions which are difficult to assess and for comorbid patients who are medically unfit for surgery. Our study strongly advocates the use of sclerotherapy as the first line treatment for ABC, considering its clinical and radiological efficacy.

Short-Term Analysis of the Changes in the Bone Mineral Density of the Proximal Femur After Uncemented Total Hip Arthroplasty: A Prospective Study of 110 Patients.

Introduction Mechanical loading continuously exposes the bone to remodeling processes. Increased load leads to a gain in bone mass, and reduced load results in a loss. After inserting a prosthesis, the proximal femur is bypassed in loading as the bodyweight shifts distally. This lack of load induces bone resorption according to Wolff's law. To avoid this bone resorption, the implant's bending stiffness should be less than the femoral bone. Dual-energy X-ray absorptiometry (DEXA) is a well-accepted method to measure periprosthetic bone mineral density (BMD) after total hip arthroplasty (THA). Since the strength and durability of the fixation of a femoral prosthesis in cementless hip arthroplasty depend largely on the quantity and quality of the surrounding bone, preoperative and postoperative evaluation of the quantity and quality of the femoral bone is very important in the long-term prognosis of hip arthroplasty. Materials and methods A prospective study of 110 patients in the age group of 25-60 years who underwent uncemented total hip arthroplasty in our tertiary healthcare institution was performed. An uncemented, fully hydroxyapatite-coated implant from a single manufacturer was used in all the patients. All the patients were mobilized on the first post-operative day. The BMD was measured at the proximal femur and the distal tip using a DEXA scan. Gruen zones were used for calculating BMD at different anatomical locations in the femur, with particular importance to zones 1, 4, and 7. Results The pre-operative BMD in all zones measured, viz. zones 1, 4, and zone 7 of the affected side, was found to be significantly lower as compared to the BMD values on the control side (P< 0.05). The mean change in the mean BMD was calculated for all the zones and compared with each other using an unpaired t-test. The mean BMD changes were found to be significantly higher in zone 7 in comparison to both zones 1 and 4 (p<0.05). Conclusion Significant periprosthetic bone loss after uncemented THA in the femur was noted in Gruen zones 1, 4, and 7 during the first six months after THA, with the greatest bone loss in the femoral calcar area (zone 7). The lower the preoperative BMD of the patient, the greater the postoperative bone loss.

Isolated L5 nerve root injury without osseous disruption in a case of gunshot injury to the paediatric spine-A case report.

INTRODUCTION: There exists sparse literature on Gunshot injuries (GSI) to the pediatric spine, its natural course, management protocols and outcomes following surgical intervention. Here, we present a projectile injury to the paediatric lumbar spine without any osseous disruption in a 5-year-old child requiring surgical management. CASE PRESENTATION: A 5-year-old child presented with a gunshot injury to the pediatric lumbar spine. On radiological imaging, there was no osseous disruption and an intraspinal canal projectile was embedded in an organised infected complex, compressing onto the left-sided L5 traversing nerve root with resultant grade 4 motor power of the left Extensor Hallucis Longus (EHL). Under fluoroscopic guidance using two separate mini-open incisions, the pellets were extracted. One from the spinal canal through left-sided L4 laminotomy and the other from the right paraspinal region. Post-surgical decompression and pellet retrieval there was gradual recovery to grade 5 motor power of Left EHL and improvement in the general condition of the child. CONCLUSION: The absence of osseous disruption can be attributed to the size of the projectile, widely spaced interlaminar spaces in the lumbar spine due to the absence of lumbar lordosis in the pediatric group and flexibility of the pediatric spine owing to its ligamentous laxity.

Evaluation of functional outcome and neurological recovery pattern in patients with retro-thecal tubercular epidural abscess managed at a tertiary center.

We performed a retrospective observational study to analyze the neurological recovery pattern in patients with a sub-laminar retro-thecal epidural abscess managed at our tertiary apex center from 2014 to 2020. We evaluated the Maximal Spinal Cord Compression (MSCC) ratio on Magnetic Resonance Imaging (MRI), the time interval between the appearance of neurological deficit and the initiation of management, spasticity as per Modified Ashworth Scale, presence of drug resistance, and the Lower Extremity Motor Score (LEMS). All patients were given anti-tubercular chemotherapy. We surgically managed 8 patients of which 6 required decompression alone, while 2 patients required additional instrumentation. 2 patients were managed conservatively of which 1 responded favorably to conservative treatment while the other patient showed a worsening of neurology following the detection of drug resistance and abrupt discontinuation of chemotherapy. The mean LEMS on admission was 20.2, which improved to 38.5 at the end of 1 year (p-value <0.05). The patients in whom the time interval between the onset of neurological deficit and the initiation of management was fewer than 6 weeks showed better LEMS and milder or absent spasticity at follow-up (p-value <0.05). The MSCC ratio did not have a significant correlation with the LEMS (p-value >0.05).

Are we neglecting long-term effects of vertebral shortening on pulmonary function in spinal tuberculosis?

PURPOSE: In developing part of the world, it is common to see complete destruction of vertebral bodies in tuberculosis. Our study aims to assess the effect of spinal tuberculosis with vertebral shortening on pulmonary function. METHODS: Fifty cases of spinal TB (14 males, 36 females) managed both operatively and non-operatively, who presented to tertiary care institute between years 2011 and 2016 were assessed. Vertebral height loss was assessed by spinal deformity index (SDI). All patients underwent pulmonary function testing using same equipment sitting in upright position. RESULTS: Mean age was 27.9 years (27.9 ± 11.9). 11 patients with mean SDI of 2.7 ± 1.1 showed normal lung function. 36 patients showed restrictive pattern of which 12 were mild, 14 were moderate and 10 showed severe pattern with a mean SDI of 3.8 ± 1.2, 5.6 ± 1.3 and 6.1 ± 1.4, respectively. 3 cases showed obstructive pattern. As the apex of curve shifted proximally, FVC% reduced. Increase in SDI value was associated with a fall in the vital capacity and FEV1. Increase in the kyphotic angle was associated with a deleterious effect on PFT results. CONCLUSIONS: Risk stratification of pulmonary dysfunction resulting from vertebral body height loss due to kyphosis will emphasize the need for early detection of spinal tuberculosis before deformity occurs.

Management Dilemma of a Neuropathic Knee in a Known Case of Larsen Syndrome: A Case Report.

Introduction: Larsen syndrome (LS) is a rare genetic disorder affecting mainly the connective tissues. It is characterized by characteristic facial anomalies, cervical kyphosis, cardiorespiratory disorders, and multiple joint dislocations. We present a case of a 15-year-old male with unstable neuropathic knee joint instability in a known case of LS. The paucity of literature on the management of this rare condition puts an orthopedician in dilemma regarding the optimal treatment. Case Report: A 15-year-old male, known case of LS, presented to our outpatient department with pain and instability in the right knee for 2 years. Clinically, the patient was having syndromic facies. The diagnosis of LS was confirmed on gene mapping. The right knee was swollen with medial joint line tenderness and restricted flexion. The patient had coronal plane valgus instability. The hypertrophied synovium eroded the articular surface. The radiograph of knee was suggestive of neuropathic arthropathy in fragmentation stage. Conclusion: Orthopedician should be aware of such rare entity with its bony and soft-tissue manifestations. Neuropathic knee is not an absolute contraindication to total knee replacement, especially with advanced prosthesis. Primary arthrodesis to be considered in young adults with instability.

Is Bilateral Sequential Total Hip Replacement as Safe an Option as Staged Replacement? A Matched Pair Analysis of 108 Cases at a Tertiary Care Centre.

BACKGROUND: Rationale for symptomatic severe bilateral arthritis of the hip is sequential bilateral THR completed under the same anaesthesia. The rarity of procedures and apprehension of complications preclude the widespread use. MATERIALS AND METHODS: Retrospective analysis of prospectively collected data from 108 patients (216 hips) with bilateral arthritis who underwent total hip arthroplasties was done: out of which 54 patients (108 hips) underwent a single-stage sequential procedure (sequential group) and a matched group of 54 patients (108 hips) underwent a two-stage procedure at different admissions (staged group). Patients were matched according to age (± 2 years), gender, American Society of Anaesthesiologists classification, perioperative management protocol and diagnosis. The mean duration of follow-up for sequential group was 5.1 years while that of staged group was 5.3 years. RESULTS: Most patients (88.88%) were operated with uncemented implants having ceramic on ceramic bearing surfaces under spinal or general anaesthesia. The operating time, post-op limb length and functional outcomes of both groups were comparable. Although the total estimated blood loss was significantly less in the sequential group (502 ml) as compared to the staged group (570 ml), the mean blood transfusion requirement was significantly higher (1.6 units) in the sequential group as compared to that in the staged group (0.9 units). The mean cumulative length of hospital stay was significantly longer in the staged group (23 days) compared with the sequential group (16 days). CONCLUSION: Single-stage bilateral total hip arthroplasty is a safe and viable option when performed with expertise in appropriately selected patients without any surge in complications.

Pharyngocutaneous Fistula and Horner's Syndrome following Loosening of Locking Screw of Anterior Cervical Plating: A Rare Case Report and Management.

We hereby present a rare case of pharyngocutaneous fistula associated with locking screw loosening causing internal cricopharynx perforation and Horner's syndrome following anterior cervical plating. A 27-year-old male patient had undergone anterior cervical plating at C5-C7 level due to gunshot injury to the neck, and 1 month postsurgery, he developed fistula in the neck showing discharge of consumed food contents. He presented to us 1 year postsurgery with the discharging fistula, left upper-limb weakness, and Horner's syndrome that developed after surgery. The previously unexplored right side was used to remove implant, and owing to solid union at corpectomy, no additional fixation was performed. Intraoperatively, pharyngeal wall dehiscence was observed. Attempt of removal of impinged screw was abandoned since it migrated into the esophagus. Serial abdomen radiographs revealed successive passage of screw through the gastrointestinal (GI) tract until it could not be visualized. As the patient showed reduced discharge, a GI surgeon gave a conservative trial with nasogastric intubation. Currently, fistula is showing minimal discharge with no food. Having knowledge of this possible rare outcome and awareness of various multidisciplinary approaches for management makes practicing spine surgeon equipped to handle such undesirable complications.
