Injury Mechanisms of Hip Fractures in India / 대한고관절학회지

Purpose@#Hip fractures are a major cause of morbidity and mortality in the elderly; however, the current literature on the injury patterns of hip fractures in India is lacking. Understanding the injury profile of these patients is important to develop targeted interventions to prevent hip fractures. @*Materials and Methods@#This was a prospective study of all hip fracture patients aged 50 years or older admitted from February 2019 to December 2019. Details about the injury were recorded by an in-person interview.Multivariate logistic regression analysis was used to identify the factors associated with any particular injury mechanism. @*Results@#Two hundred and eighty-three hip fractures were included. The mechanism of injury for the majority of patients was a fall from a standing height (n=217, 76.7%) while 60 patients (21.2%) were injured as the result of a road traffic accident (RTA). Slipping on a wet floor (n=49, 22.6%) and change in posture (n=35, 16.1%) were the most commonly reported reasons for falling. Pedestrian injuries were the most common form of RTA (n=29, 48.3%). Increasing age (P<0.001) and female sex (P=0.001) were associated with fall as the mode of injury while sustaining another fracture in addition to hip fracture (P=0.032) was associated with RTA as the mode of injury. @*Conclusion@#A fall from standing height is the predominant mode of injury among elderly hip fractures especially among women. Environmental hazards and postural changes are responsible for the majority of falls while pedestrian accidents contribute to a majority of the RTAs.

Morphological Changes in the Ligamentum Flavum in Degenerative Lumbar Canal Stenosis: A Prospective, Comparative Study

Methods@#Forty patients were prospectively recruited and divided into two groups: group 1 included 20 patients with degenerative LCS aged >55 years and group 2 included patients with LDH aged <35 years. The ligament flava were collected during the patients’ surgery. The features noted on histopathological examination included the fibrosis score, the loss of elastic fibers, calcification, chondroid metaplasia, mucinous degeneration, vascularization, long septa, clefts, granulation tissue, and ganglion-like cysts. The features noted on electron microscopic examination included the elastic fiber thickness, the quality of elastic fibers, the elastic:collagen ratio, calcification, melanin fibers, remnants of necrotic cells, and electron-dense material in the LF. All parameters were compared between group 1 and group 2. @*Results@#On histopathological examination, the two groups exhibited significant differences regarding three parameters: chondroid metaplasia, long septa, and ganglion-like cysts. On electron microscopy examination, significant differences were observed between the two groups regarding two parameters: the quality of elastic fibers and the elastic:collagen ratio. @*Conclusions@#Characteristic morphological changes may be noted on histopathological and electron microscopic examination that mark the degenerative changes in the LF that contribute to the occurrence and pathogenesis of degenerative LCS.

Minimally invasive osteosynthesis of distal tibial fractures using anterolateral locking plate: Evaluation of results and complications / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>Soft tissue healing is of paramount importance in distal tibial fractures for a successful outcome. There is an increasing trend of using anterolateral plate due to an adequate soft tissue cover on ante- rolateral distal tibia. The aim of this study was to evaluate the results and complications of minimally invasive anterolateral locking plate in distal tibial fractures.</p><p><b>METHODS</b>This is a retrospective study of 42 patients with distal tibial fractures treated with minimally invasive anterolateral tibial plating. This study evaluates the bone and soft tissue healing along with emphasis on complications related to bone and soft tissue healing.</p><p><b>RESULTS</b>Full weight bearing was allowed in mean time period of 4.95 months (3-12 months). A major local complication of a wound which required revision surgery was seen in one case. Minor complications were identified in 9 cases which comprised 4 cases of marginal necrosis of the surgical wound, 1 case of superficial infection, 1 case of sensory disturbance over the anterolateral foot, 1 case of muscle hernia and 2 cases of delayed union. Mean distance between the posterolateral and anterolateral incision was 5.7 cm (4.5-8 cm).</p><p><b>CONCLUSION</b>The minimally invasive distal tibial fixation with anterolateral plating is a safe method of stabilization. Distance between anterolateral and posterolateral incision can be placed less than 7 cm apart depending on fracture pattern with proper surgical timing and technique.</p>

Complications in the management of closed high-energy proximal tibial plateau fractures / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To report complications in the management of complex closed proximal tibial fractures.</p><p><b>METHOD</b>A retrospective study was conducted to analyze the infectious and noninfectious complications encountered in the management of high-energy Schatzker type V and VI tibial plateau fractures. All patients were treated at the level 1 trauma centre between January 2011 and March 2014. Sixty two patients were included in the study. The mean patient age was (43.16 ± 11.59) years with 60 males and 2 females. Infectious complications like superficial and deep infection, wound dehiscence, malalignment in the immediate postoperative period and in follow-up period were noted.</p><p><b>RESULTS</b>The overall complication rate was 30.65% (19 out of 62). Infectious complications were noted in 20.97% cases (13/62). In majority of the cases (8/13), superficial infection was seen which managed with regular dressing and antibiotic administration. The patients (5/13) who had developed deep-seated infection were subjected to repeated debridements, flap coverage, implant removal or amputation depending upon the host response. Thirteen patients had experienced noninfectious complications. Hardware related complications were noticed in six patients and four among them received a secondary procedure. Malalignment was observed in seven patients but only single patient underwent subsequent operative intervention.</p><p><b>CONCLUSION</b>Proximal tibial plateau fractures especially Shatzker type V and VI are associated with extensive soft tissue damage even in closed injuries. The complications encountered in the management of these fractures can be minimized with appropriate patient selection and minimal soft tissue dissection.</p>

Neglected Thoraco Lumbar Traumatic Spine Injuries

STUDY DESIGN: Retrospective study. PURPOSE: To outline the etiology, complications and management difficulties encountered in the management of neglected thoracolumbar spine injuries. OVERVIEW OF LITERATURE: The English literature describes overlooked diagnosis as the most common cause of neglected spine injuries. However, the reasons differ in developing or under-developed nations. Moreover, there is scarcity of literature about the neglected spinal injuries. METHODS: Patients presenting with thoracolumbar traumatic injuries who had not received any form of treatment for more than three weeks were included in the study. The demographic details, operative procedure performed and complications encountered, along with American Spinal Injury Association grade and spinal cord independence measure score recorded on the history sheets were noted. The data were analyzed. RESULTS: Forty patients were included in the study. Inadequate treatment at the first contact hospital (45%) followed by late presentation (38%) and missed injury (17%) were the major etiological factors for the neglected traumatic injuries in the thoracolumbar spine. The most common complications seen in the management of these cases were pressure sores (58%), back pain (57%), urinary tract infection (42%) and residual kyphotic deformity (42%). CONCLUSIONS: Management of neglected thoracolumbar injuries is challenging. The delay in presentation should not prevent spine surgeon in proceeding with operative intervention as good results can be expected.

On-table reconstruction and fixation of Mason type III radial head fractures / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To evaluate the functional and radiological outcome of comminuted radial head fractures, which were not amenable for classical open reduction with internal fixation, treated by on-table reconstruction and fixation using low profile plates.</p><p><b>METHODS</b>We reviewed 6 patients of Mason type III radial head fractures treated by on-table reconstruction technique between 2011 and 2013. There were 5 men and 1 woman with a mean age of 35 years (range 25-46 years). All surgeries were carried out at our tertiary care level 1 trauma centre within a mean of 3 days (range 1-8 days) from date of injury using on-table reconstruction technique. The functional outcome was measured using elbow functional rating index described by Broberg and Morrey and the patient-based Disabilities of the Arm, Shoulder and Hand (DASH) outcome measure.</p><p><b>RESULTS</b>The mean follow-up period was 25 months. The average elbow flexion was 135°(range 125°-140°) and theaverage flexion contracture was 5°(range 0-10°). The average supination and pronation was 75°(range 70°-80°) and 70°(range 65°-82°) respectively. According to Broberg and Morrey scoring system, the average score was 90 points (range 75-100). The mean DASH score was 2.49 points.</p><p><b>CONCLUSION</b>On-table reconstruction and fixation of comminuted radial head fractures using low profile plates is a reasonable option. The reconstructed radial head acts as spacer and provides reasonably good results and no surgical intervention is required for asymptomatic nonunion of these fractures regardless of the radiological findings.</p>

Surgical treatment of proximal humerus fractures using PHILOS plate / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To evaluate functional outcome and complications of open reduction and internal fixation with proximal humeral internal locking system (PHILOS) plate for proximal humerus fractures.</p><p><b>METHODS</b>We reviewed 51 patients who underwent open reduction and internal fixation with PHILOS plate between the years 2007 to 2012. There were 35 men and 16 women with a mean age of 38 years (range 24-68). There were 41 patients in the age group of <60 years and 10 patients in the age group of >60 years. According to Neer classification system, 8, 15 and 23 patients had 2-part, 3-part, and 4-part fractures, respectively and 5 patients had 4-part fracture dislocation. All surgeries were carried out at our tertiary care trauma centre. Functional evaluation of the shoulder at final follow-up was done using Constant-Murley score.</p><p><b>RESULTS</b>The mean follow-up period was 30 months (range 12-44 months). Two patients were lost to follow-up. Of the remaining 49 patients, all fractures were united clinically and radiologically. The mean time for radiological union was 12 weeks (range 8-20 weeks). At the final follow-up the mean Constant-Murley score was 79 (range 50-100). The results were excellent in 25 patients, good in 13 patients, fair in 6 patients and poor in 5 patients. During the follow-up, four cases of varus malunion, one case of subacromial impingement, one case of deep infection, one case of intraarticular screw penetration and one case of failure of fixation were noted. No cases of avascular necrosis, hardware failure, locking screw loosening or nonunion were noted.</p><p><b>CONCLUSION</b>PHILOS provides stable fixation in proximal humerus fractures. To prevent potential complications like avascular necrosis, meticulous surgical dissection to preserve vascularity of humeral head is necessary.</p>

Acute femoral artery pseudoaneurysm due to lesser trochanter fragment: an unusual complication of an intertrochanteric fracture / 中华创伤杂志(英文版)

False aneurysm of the femoral artery is a rare complication of intertrochanteric fracture. Most of these situations are due to iatrogenic trauma or the trauma itself and are rarely caused by dislocated bone fragments. Here we report a case of a 72-year-old man who presented acutely with a pseudoaneurysm of the superficial femoral artery from the spike of a lesser trochanter fragment. Percutaneous endovascular treatment of the pseudoaneurysm with a covered stent was undertaken on an urgent basis. Five days later, the patient was operated upon and the lesser trochanter fragment was excised through an anterior incision and the intertrochanteric fracture was fixed using dynamic hip screws. The fracture was united at 10 weeks. At one-year's follow-up, there were no graft-related complications. This case illustrates that an intertrochanteric fracture with a displaced lesser trochanter fragment can present acutely with bleeding and a pseudoaneurysm of the femoral artery.
