Publication A Comparative Study on Epidemiology, Spectrum and Outcome Analysis of Physical Trauma cases Presenting to Emergency Department of Dhulikhel Hospital, Kathmandu University Hospital and its Outreach Centers in Rural Area(Kathmandu University, 2013) Shrestha, R; Shrestha, SK; Kayastha, SR; Parajuli, N; Dhoju, D; Shrestha, DABSTRACT Background Physical trauma is one of the major cause of mortality and morbidity among young and active age group and its increasing trend is of main concern. There are only few studies concerning the spectrum of physical trauma in Nepal. Objective This study aims to evaluate the epidemiological spectrum, the extent, severity of the physical trauma and the outcome evaluation of patients with physical trauma over a period of one year in the emergency department of the Kathmandu University Hospital and compare the same parameters with those patients presenting to the various outreach centers of the hospital in the community. Methods Patient treatment files from the emergency department and the reports from various outreach centers were retrieved for a period of one year (May 2011 to April 2012). Epidemiological information, mode, type and anatomic location of injuries were recorded. Outcome evaluation was assessed by number of patients discharged from emergency department of the hospital or the outreach centers after the treatment, patients admitted for inpatient management and referred to other centers for further specialty management. Result In a period of one year, total 2205 (20%) of physical trauma cases presented to the emergency department and 1994 (6.12%) in the outreach centres. Most commonly involved age group in physical trauma both in Hospital set up and in Community set up were the young adults (15 to 49 years). Fall from height was the commonest mode of injury followed by road traffic accidents among the patients coming to the hospital while significant number of trauma patients coming to outreach centers were due to fall from height. In the hospital set up, 1525 (69.2%) of the cases were discharged while 537 (24.4%) needed inpatient management and 85 (3.8%) needed referral to other centers for the specialty management. In case of outreaches, half of the patients were discharged after the primary treatment and almost another half were referred to the hospital, mainly for need of further investigations. Conclusion Fall related injuries and road traffic accidents are the most common mode of trauma in the hospital set up and fall related injuries are the single most important mode of trauma seen in the outreaches. Mostly young adults in their active period of life are involved in physical trauma so appropriate preventive measures through public health approach should be included in comprehensive trauma management for reducing mortality and morbidity rates related to physical trauma.

Objective To analyses epidemiology, types of acetabular fracture and functional and radiological outcome of patients with acetabular fracture treated with open reduction and internal fixation (ORIF). Method Inpatients hospital records of patients treated with ORIF in between June 2007 to June 2014 were evaluated. Patient’s demographic data, mode of injury, injury hospital interval, injury surgery interval, associated injuries, surgical approach, total hospital stay and peri and post-operative complications were recorded and radiological and functional outcomes were evaluated. Result Thirty three patients (Male: 24 Female: 9) with average age 39 years (range: 21 to 65 years) were operated for acetabular fracture. Twenty one patients (63%) had injury related with motor vehicle accidents and nine (24%) of them had motorbike accidents. Injury hospital interval ranges from 7 to 36 days. Average injury-surgery interval was 21 days and average hospital stay was 22 days. Bicolumnar fractures were found in 15. Nine patients had dislocation of hip and 15 had concomitant other injuries. Biculumanr fixation was performed in 15 patients, posterior column and or wall in nine with Kocher Langenbeck approach and anterior column and or wall in other nine with ilio-inguinal approach. Radiological reduction was anatomical in 18; excellent/good functional outcome was in 26 and radiological outcomes were excellent in 14. Three patients had developed Hypertopic ossification. Follow up period ranged from 6 to 48 months and 15 patients (45%) had follow up >2 years. Conclusion Acetabular fractur can be effectively managed with ORIF and have predictable and comparable functional and radiographic outcomes. Upgrading the existing facilities and training of orthopedic surgeon for acetabular fracture management is important to shorten injury-surgery interval due to lack of such facilities.

Implants are generally removed after the purpose of keeping implant is solved by healing of the fracture, but there is no consensus whether routine implant removal should be a policy for all fractures that were fixed. Objective This study aims to analyze the epidemiology and outcome of implant removal surgery carried out in the past three years in Kathmandu University Hospital. Methods Patients who underwent implant removal between 2010 January to 2012 December constituted the study cohort. Demographic data, indications, types of hardware and location of fractures were recorded. Similarly, duration of surgery, type of anesthesia and duration of hospital stay were recorded. All the patients who had undergone implant removal in this three years period were called for follow up examination but those who were not able to come were interviewed on telephone. Results There were 275 implant removals constituting 7.8% of total orthopedic operations and 26.3% of fracture fixations. Male to Female ratio was 189: 86. Pediatric age group (34.5%) had the highest incidence of implant removal. Moderate sized implants were the commonest hardwares removed (63.2%). Femur (27.3%) followed by radius (26.9%) were the commonest bone for implant removal. Average operative time was 47.3 minutes with average hospital inpatient stay of 2.6 days. Commonest indication for the implant removal procedure was pain (45%). Conclusion Implant removal procedures are one of the most commonly performed elective orthopedic surgeries. Though, after orthopedic implants removal, pain relief can be expected but it is not so predictive and hence patient should be well counseled before and the indications for implant removal has to be evaluated for better patient satisfaction and safety.

Conventionally, open biopsy methods are used. With availability of CT scan, MRI, percutaneous transpedicular vertebral biopsy has now become popular as a minimally invasive technique for biopsy of vertebral lesion. Objective To describes technique and to analyzes safety and feasibility of percutaneous transpedicular vertebral biopsy with fluoroscopy guidance for thoracic and lumbar vertebral body lesions. Method Twenty three patients who underwent percutaneous transpedicular vertebral biopsy under fluoroscopy guidance were retrospectively evaluated for demographic data, indication for biopsy, anatomical locations, histological/microbiological diagnosis, complications and final outcome of treatment. True positive, true negative, false positive and false negative cases were defined. Result There were 17 males and 6 female patients of mean age 47 (range 22-73 years). Biopsies were performed in 17 dorsal and six lumbar vertebral bodies. Adequate sample were obtained in all cases. Seventeen patients (12: tubercular pathology, 1: primary tumor, 3: metastasis, 1: osteoporotic fracture) had definitive histological/ microbiological diagnosis. Four patients had no granuloma and tumor. Two had histological features of chronic non specific inflammation. True positive cases were 17, true negative were four and false negative case were two. Overall accuracy was 92%. One patient developed small hematoma at biopsy site. Conclusion Fluoroscopy guided percutaneous transpedicular biopsy of is a safe procedure with high adequacy and accuracy and low complication rate for thoracic and lumbar vertebral body lesion.

Controversy exists as to what amount of angulation, displacement, and rotation constitutes an acceptable reduction. Objective To review union time and functional outcome of pediatric diaphyseal forearm bone fracture managed with intramedullary rush pin by closed or open reduction. Methods Fifty patients with both bone fracture of forearm were treated with intramedullary rush pin by closed or open reduction were included in the study and followed up for minimum six months for radilological and functional outcome. Results Out of 50 patients, 31 underwent closed reduction and 19 underwent open reduction. All fractures maintained good alignment post operatively. Forty seven patients had excellent results with normal elbow range of motion and normal forearm rotation and three patients had good results. In all patients good radiological union was seen in three months time. Eight patients had minor complications including skin irritation over prominent hardware, backing out of ulnar pin, superficial skin break down with exposed hardware. Twenty-three (46%) patients had undergone implant removal at an average of 6 months (range 4-8 months) under regional or general anesthesia Conclusion Fixation with intramedullary rush pin for forearm fracture is an effective, simple, cheap, and convenient way for treatment in pediatric age group. KEY WORDS pediatric forearm fracture, rush pinPublication Ipsilateral Supracondylar Fracture and Forearm Bone Injury in Children: A Retrospective Review of Thirty one Cases(Kathmandu University, 2011) Dhoju, D; Shrestha, D; Parajuli, N; Dhakal, G; Shrestha, RABSTRACT Background Supracondylar fracture and forearm bone fracture in isolation is common musculoskeletal injury in pediatric age group But combined supracondylar fracture with ipsilateral forearm bone fracture, also known as floating elbow is not common injury. The incidence of this association varies between 3% and 13%. Since the injury is rare and only limited literatures are available, choosing best management options for floating elbow is challenging. Method In retrospective review of 759 consecutive supracondylar fracture managed in between July 2005 to June 2011, children with combined supracondylar fracture with forearm bone injuries were identified and their demographic profiles, mode of injury, fracture types, treatment procedures, outcome and complications were analyzed. Result Thirty one patients (mean age 8.91 yrs, range 2-14 yrs; male 26; left side 18) had combined supracondylar fracture and ipsilateral forearm bone injury including four open fractures. There were 20 (64.51%) Gartland type III (13 type IIIA and 7 type III B), seven (22.58 %) type II, three (9.67 %) type I and one (3.22 %) flexion type supracondylar fracture. Nine patients had distal radius fracture, six had distal third both bone fracture, three had distal ulna fracture, two had mid shaft both bone injury and one with segmental ulna with distal radius fracture. There were Monteggia fracture dislocation, proximal ulna fracture, olecranon process fracture, undisplaced radial head fracture of one each and two undisplaced coronoid process fracture. Type I supracondylar fracture with undisplaced forearm were treated with closed reduction and long arm back slab or long arm cast. Displaced forearm fracture required closed reduction and fixation with Kirschner wires or intramedullary nailing. Nineteen patients with Gartland type III fracture underwent operative intervention. Among them nine had closed reduction and K wire fixation for both supracondylar fracture and forearm bone injury. One patient with closed reduction and long arm cast application for both type III supracondylar fracture and distal third radius fracture developed impending compartment syndrome and required splitting of cast, remanipulation and Kirschner wire fixation. There were three radial nerve, one ulnar nerve and one median nerve injury and two postoperative ulnar nerve palsy. Three patients had pin tract related complications. Among type III, 16 (80%) patients had good to excellent, two had fair and one gad poor result in terms of Flynn’s criteria in three months follow up Conclusion Displaced supracondylar fracture with ipsilateral displaced forearm bone injuries need early operative management in the form of closed reduction and percutaneous pinning which provides not only stable fixation but also allows close observation for early sign and symptom of development of any compartment syndrome.

Despite higher nonunion rates in initial open reduction and internal fixation, understanding the problem better and taking in accounts of previous shortcomings, such fractures can be optimally treated by open reduction and internal fixation with reconstruction plate. Objective To study the outcome of middle third clavicle fracture treated with superior reconstruction plating in terms of function using Constant shoulder score, union time and rate, complications and patient satisfaction. Methods Twenty patients with displaced middle third clavicle fracture (Edinburg type 2) treated with open reduction and internal fixation with reconstruction plate implanted in superior surface were prospectively followed for at least one year after surgery. Results There were 20 patients, 16 males and 4 females. The mean age of the patients was 31.5 years with SD 11.5 years (range 15-60 years) and 5 patients (25%) had associated injuries. All fractures united in 16 weeks or less in near anatomic position with complication in 2 (5%) patients, one deep infection and one frozen shoulder which on subsequent management recovered well. There was no nonunion or implant failure. The average Constant score was 97.45 in one year follow up and the patients were relatively satisfied with the treatment.The most common indication (25%) for hardware removal was young age of the patient, hardware prominence and occasional discomfort Conclusion This small series shows that displaced midshaft clavicle fracture can be optimally treated with operative fixation implanting the reonstruction plate in superior surface with six cortical purchases on either side and supervised physiotherapy, although subsequent surgery for implant removal might be necessary.

Unstable ankle fractures are usually treated with operative management. Objective To find out demographic and the relationship between various clinical variables and outcome of operative treatment in ankle fractures in patient who underwent operative treatment for bimalleolar ankle fractures. Method A retrospective observational study of 32 patients who underwent operative treatment of bimalleolar ankle fracture in between January 2012 and December 2015 at Dhulikhel Hospital, Kathmandu University Hospital was performed. Skeletally mature individual of age greater than 16 years with bimalleolar ankle fractures operated within two weeks of injury were included in the study. Operating surgeon chose the type of surgery and implants required for the patient. Post operatively patients were kept in non-weight bearing for six weeks. Result The average age of the patients was 36.72 ± 19.97 years. The most common cause for the injury was twisted ankle. The mean follow up period of the patients was 20.94 ± 16.32 months. The most common fracture type was Weber B (supination external rotation injury). Most common technique for fixation for medial malleolus fracture was open reduction and modified tension band. Most of the lateral malleolus fractures were treated with open reduction and fixation with reconstruction plate. Six cases were treated with syndesmotic screws. Most of the patients had excellent AOFAS score with mean score of 90.56 ± 10.92 out of maximum 100. Average pain score was 32.81 ± 36.34 out of 40, average function score was 47.81 ± 6.05 out of 50 and average alignment score was 9.94 ± 0.35 out of 10. Conclusion The outcome of surgically treated bimalleolar ankle fractures was excellent for our patients. The fracture patterns and requirement of syndesmotic screw failed to show any significance when comparing the outcome.

Open reduction and fixation in an already compromised soft tissue and hemodynamically unstable patient causes more soft tissue injury, heamatoma, infection and neurovascular injury. Percutaneous ilio- sacral joint fixation can be an alternative technique for sacro-iliac joint injury and sacral fracture. Objective To evaluate technique and safety of percutaneous ilio-sacral screw fixation in supine position under single fluoroscopy guidance for sacral fracture and sacro-iliac joint disruption. Method Twenty one patients either with sacral fracture or sacro-iliac joint disruption with percutaneous ilio-sacral screw fixation with cannulated cancellous screw fixation in between 2008 to 2014 were retrospectively evaluated including AP, inlet and outlet views of pelvis X rays and CT scan. Tile’s classification and Dennis classification were used for pelvis and sacral injury. Result Thirty five percutaneous ilio-sacral screws were placed (Male: 6, Female: 15; range: 15 to 54) for sacral fracture involving zone 2 (8 with sacral fracture only and 5 with pelvis injury; Tile’s type B in four and type C in one) and sacro-iliac joint injury (Tile’s type B in three and type C in five). Commonest mode of injury was motor vehicle accidents (10) followed by fall related injury (6). Injury hospital interval and injury surgery interval was five hours to 13 days and 2 to 20 days respectively. Follow period was 3 months to 6 years. One patient developed post-operative deep vein thrombosis and another patient had post-operative haematoma. Two screws were juxtra-foramial. Good to excellent outcome were in 16 patients, fair in four and poor in one patient (Majeed Scoring). Conclusion Percutaneous ilio-sacral screw fixation for sacro-iliac joint injury and sacral fracture with C arm guidance is safe and minimally invasive technique. Clear images and accurate interpretation of X-rays, CT scans and per operative C arm images are important to avoid malpositioning of screws and iatrogenic neurovascular injuries.

Open reduction and fixation with Herbert Screw though technically demanding procedure can yield excellent results and prevents complication like nonunions and loss of wrist function. Objectives To assess clinical outcome and radiological union of scaphoid fracture after operative management following Herbert screw fixation in patient attending Dhulikhel Hospital. Methods All scaphoid fracture, treated from Feb 2007 till Feb 2011, were retrospectively studied in Dhulikhel Hospital, Kathmandu University Hospital. Fifteen patients with scaphoid fractures were treated with Herbert screw. Fourteen were males and one was female. Serial radiographs were taken to assess radiographic union and functional outcome was assessed using Modified Mayo wrist score. Results Out of 15 patients, 13 scaphoid had waist fractures and two had proximal pole factures. All scaphoid were treated with open reduction and Herbert screw fixation either by volar approach or by dorsal approach. All fractures maintained good alignment post operatively. Nine (60%) patients had excellent results with normal wrist range of motion, five (33.3%) patients had good results and one (6.7%) patient had poor outcome. In 14 (93.3%) patients good radiological union was seen at final follow up at six months time. Conclusion Fixation with Herbert screw for scaphoid fracture is an effective and convenient way of treatment with satisfactory functional outcome and less complication.

In the absence of provision of medical insurances, worker’s compensation and sick leave, predictors for outcome after lumbar disc herniation surgery will be different in Nepalese population. Objective To evaluate different clinical variables that can affect outcome after lumbar disc herniation surgery. Method Among 88 patients who underwent microdisectomy for lumbar disc herniation, 63 patients (43 male, 20 female) with follow up at least six months were retrospectively evaluated for clinical variables which can affect Oswestry disability index (ODI) score, its interpretation and Mcnab classification of post operative outcome. Result Average age of patients was 42.54±8.60 years. Mean follow up period was 34.89±23.80 months (range 6 -111 months). Thirty four patients had follow up period > 24 months. Mean ODI score before surgery and at final follow up was 37.87±8.76 vs 7.78±7.7; (p=0.00). Success rate was 90.47% (change in ODI score at least by 10), 93.65% (ODI score interpretation <40%), and 85.71%. (Mcnab outcome excellent and good). Significant correlation was found between age and ODI at final follow up but not with duration of symptoms. Male, non alcoholic, low level of education, numbness as a predominant symptom, disc at L4-L5 were significantly associated with better ODI at final follow up. For ODI score interpretation, gender, smoking habit, presence of leg pain as a predominant symptom were statistically significant factors whereas smoking and drinking habit, level of education, occupation, back pain and numbness as predominant pre-operative symptom, types of disc in MRI were significantly related to Mcnab outcome. There was 9.5% peri- or post-operative complications and recurrence in seven patients. Conclusion Age, gender, smoking and drinking habit, level of education, occupation, types of disc in MRI are important variables for ODI score, ODI score interpretation and Mcnab outcome.
