Posttraumatic stiff elbow p. 4
Ravi Mittal
Posttraumatic stiff elbow is a frequent and disabling complication and poses serious challenges for its management. In this review forty studies were included to know about the magnitude of the problem, causes, pathology, prevention, and treatment of posttraumatic stiff elbow. These studies show that simple measures such as internal fixation, immobilization in extension, and early motion of elbow joint are the most important steps that can prevent elbow stiffness. It also supports conservative treatment in selected cases. There are no clear guidelines about the choice between the numerous procedures described in literature. However, this review article disproves two major beliefs-heterotopic ossification is a bad prognostic feature, and passive mobilization of elbow causes elbow stiffness.

Complex AO type C3 distal femur fractures: Results after fixation with a lateral locked plate using modified swashbuckler approach p. 18
Anuj Agrawal, Vivek Kiyawat
Background: Complex AO type C3 fractures of the distal femur are challenging injuries, fraught with complications such as malunion and stiffness. We prospectively evaluated a consecutive series of patients with complex AO type C3 distal femur fractures to determine the clinicoradiological outcome after fixation with a single locked plate using modified swashbuckler approach. Materials and Methods: 12 patients with C3 type distal femur fractures treated with a lateral locked plate, using a modified swashbuckler approach, were included in the study. The extraarticular component was managed either by compression plating or bridge plating (transarticular approach and retrograde plate osteosynthesis) depending on the fracture pattern. Primary bone grafting was not done in any case. The clinical outcome at 1 year was determined using the Knee Society Score (KSS). The presence of any secondary osteoarthritis in the knee joint was noted at final followup. Results: All fractures united at a mean of 14.3 ± 4.7 weeks (range 6-26 weeks). There were no significant complications such as nonunion, deep infection, and implant failure. One of the patients underwent secondary bone grafting at 3 months. The mean range of motion of the knee was 120° ± 14.8° (range 105°-150°). Seven patients had excellent, three patients had good and two patients had a fair outcome according to the KSS at 1 year. At a mean followup of 17.6 months, three patients showed radiological evidence of secondary osteoarthritis of the knee joint. However, only one of these patients was symptomatic. Conclusion: The results of complex C3 type distal femur fractures, fixed with a single lateral locked plate using a modified swashbuckler approach, are encouraging, with a majority of patients achieving good to excellent outcome at 1 year.

Comparison of occipitocervical and atlantoaxial fusion in treatment of unstable Jefferson fractures p. 28
Yong Hu, Zhen-shan Yuan, Christopher K Kepler, Wei-xin Dong, Xiao-yang Sun, Jiao Zhang
Background: Controversy exists regarding the management of unstable Jefferson fractures, with some surgeons performing reduction and immobilization of the patient in a halo vest and others performing open reduction and internal fixation. This study compares the clinical and radiological outcome parameters between posterior atlantoaxial fusion (AAF) and occipitocervical fusion (OCF) constructs in the treatment of the unstable atlas fracture. Materials and Methods: 68 consecutive patients with unstable Jefferson fractures treated by AAF or OCF between October 2004 and March 2011 were included in this retrospective evaluation from institutional databases. The authors reviewed medical records and original images. The patients were divided into two surgical groups treated with either AAF ( n = 48, F/M 30:18) and OCF ( n = 20, F/M 13:7) fusion. Blood loss, operative time, Japanese Orthopaedic Association (JOA) score, visual analog scale (VAS) score, atlanto-dens interval, lateral mass displacement, complications, and the bone fusion rates were recorded. Results: Five patients with incomplete paralysis (7.4%) demonstrated postoperative improvement by more than 1 grade on the American Spinal Injury Association impairment scale. The JOA score of the AAF group improved from 12.5 ± 3.6 preoperatively to 15.7 ± 2.3 postoperatively, while the JOA score of the OCF group improved from 11.2 ± 3.3 preoperatively to 14.8 ± 4.2 postoperatively. The VAS score of AAF group decreased from 4.8 ± 1.5 preoperatively to 1.0 ± 0.4 postoperatively, the VAS score of the OCF group decreased from 5.4 ± 2.2 preoperatively to 1.3 ± 0.9 postoperatively. Conclusions: The OCF or AAF combined with short-term external immobilization can establish the upper cervical stability and prevent further spinal cord injury and nerve function damage.

Percutaneous endoscopic lumbar discectomy: Results of first 100 cases p. 36
Kanthila Mahesha
Background: Lumbar disc herniation is a major cause of back pain and sciatica. The surgical management of lumbar disc prolapse has evolved from exploratory laminectomy to percutaneous endoscopic discectomy. Percutaneous endoscopic discectomy is the least invasive procedure for lumbar disc prolapse. The aim of this study was to analyze the clinical outcome, quality of life, neurologic function, and complications. Materials and Methods: One hundred patients with lumbar disc prolapse who were treated with percutaneous endoscopic discectomy from May 2012 to January 2014 were included in this retrospective study. Clinical followup was done at 1 month, 3 months, 6 months, 1 year, and at yearly interval thereafter. The outcome was assessed using modified Macnab's criteria, visual analog scale, and Oswestry Disability Index. Results: The mean followup period was 2 years (range 18 months - 3 years). Transforaminal approach was used in 84 patients, interlaminar approach in seven patients, and combined approach in nine patients. An excellent outcome was noted in ninety patients, good outcome in six patients, fair result in two patients, and poor result in two patients. Minor complications were seen in three patients, and two patients had recurrent disc prolapse. Mean hospital stay was 1.6 days. Conclusions: Percutaneous endoscopic lumbar discectomy is a safe and effective procedure in lumbar disc prolapse. It has the advantage that it can be performed on a day care basis under local anesthesia with shorter length of hospitalization and early return to work thus improving the quality of life earlier. The low complication rate makes it the future of disc surgery. Transforaminal approach alone is sufficient in majority of cases, although 16% of cases required either percutaneous interlaminar approach or combined approach. The procedure definitely has a learning curve, but it is acceptable with adequate preparations.

Early results of thoraco lumbar burst fracture treatment using selective corpectomy and rectangular cage reconstruction p. 43
Bowei Liang, Guofeng Huang, Luobing Ding, Liangqi Kang, Mo Sha, Zhenqi Ding
Background: Subsidence and late fusion are commonly observed in anterior subtotal corpectomy and reconstruction for treating thoracolumbar burst fractures. The subsidence rate of this surgical method was reported from 19.6% to 75% in the literatures, which would cause treatment failure. Thus, an improvement of anterior surgery technique should be studied to reduce these complications. Materials and Methods: 130 patients of thoracolumbar burst fractures treated by minimal corpectomy, decompression and U cage, between January 2009 and December 2010 were included in this study. The hospital Ethical Committee approved the protocols. The American Spinal Injury Association (ASIA) scale, visual analog scales, and Oswestry Disability Index (ODI) scores were used for clinical evaluation. The local kyphosis angle, vertebral height (one level above the fractured vertebral to one level below), canal stenosis, and fusion status were used to assess radiological outcome. All complications and demographic data such as number of male/female patients, average age, mode of trauma, burst level involved, mean surgery time and blood lost were reported. Results: 120 patients were followed up for 24 months. Most patients had improvement of at least 1 ASIA grade, and all experienced pain reduction. The mean ODI score steadily decreased after the surgery ( P < 0.01). Approximately, 83.3% of patients achieved solid fusion at 3 months and reached 98.3% at 6 months. The kyphosis angle and radiographic height were corrected significantly after the surgery and with a nonsignificant loss of correction at 24 months (P > 0.05). The average canal stenosis index was increased from 39% to 99% after surgery. No cage subsidence or implant failure was observed. Conclusions: The clinical outcomes described here suggest that the selective corpectomy and rectangular cage reconstruction can effectively promote solid fusion and eliminate complications related to subsidence or implant failure.

Femoral bowing plane adaptation to femoral anteversion p. 49
Alp Akman, Fahir Demirkan, Nuran Sabir, Murat Oto, Cagdas Yorukoglu, Esat Kiter
Background: Femoral bowing plane (FBP) is the unattended subject in the literature. More over the femoral shaft with its bowing is neglected in established anteversion determination methods. There is limited information about the relationship between FBP and anteversion. Thus we focused on this subject and hypothesized that there could be an adaptation of FBP to anteversion. Materials and Methods: FBP is determined on three-dimensional solid models derived from the left femoral computerized tomography data of 47 patients which were taken before for another reason and comparatively evaluated with anteversion. There were 20 women and 27 men. The mean age of patients was 56 years (range 21-84 years). Results: The anteversion values were found as the angle between a distal condylar axis (DCA) and femoral neck anteversion axis (FNAA) along an imaginary longitudinal femoral axis (LFA) in the true cranio-caudal view. The FBP was determined as a plane that passes through the centre-points of three pre-determinated sections on the femoral shaft. The angles between DCA, FNAA and FBP were comparatively evaluated. The independent samples t-test was used for statistical analysis. At the end, it was found that FBP lies nearly perpendicular to the anteversion axis for the mean of our sample which is around 89° in females and 93° in males (range 78-102°). On the other hand, FBP does not lie close to the sagittal femoral plane (SFP); instead, there is an average 12.5° external rotation relative to the SFP. FBP is correlated well with anteversion in terms of FBP inclination from SFP and femoral torsion (i.e., angle between FBP and femoral neck anteversion axis (P0 < 0.001; r = 0.680 and r = −0.682, respectively). Combined correlation is perfect (R[2] = 1) as the FBP, SFP, and posterior femoral plane forms a triangle in the cranio-caudal view. Conclusions: We found that FBP adapts to anteversion. As FBP lies close to perpendicularity for the mean, femoral component positioning perpendicular to the FBP can be an alternate way in the replacement surgeries. In addition, it has been found that FBP lies externally rotated relative to the SFP.

Management of Gustilo Anderson III B open tibial fractures by primary fascio-septo-cutaneous local flap and primary fixation: The 'fix and shift' technique p. 55
PR Ramasamy
Background: Open fractures of tibia have posed great difficulty in managing both the soft tissue and the skeletal components of the injured limb. Gustilo Anderson III B open tibial fractures are more difficult to manage than I, II, and III A fractures. Stable skeletal fixation with immediate soft tissue cover has been the key to the successful outcome in treating open tibial fractures, in particular, Gustilo Anderson III B types. If the length of the open wound is larger and if the exposed surface of tibial fracture and tibial shaft is greater, then the management becomes still more difficult. Materials and Methods: Thirty six Gustilo Anderson III B open tibial fractures managed between June 2002 and December 2013 with "fix and shift" technique were retrospectively reviewed. All the 36 patients managed by this technique had open wounds measuring >5 cm (post debridement). Under fix and shift technique, stable fixation involved primary external fixator application or primary intramedullary nailing of the tibial fracture and immediate soft tissue cover involved septocutaneous shift, i.e., shifting of fasciocutaneous segments based on septocutaneous perforators. Results: Primary fracture union rate was 50% and reoperation rate (bone stimulating procedures) was 50%. Overall fracture union rate was 100%. The rate of malunion was 14% and deep infection was 16%. Failure of septocutaneous shift was 2.7%. There was no incidence of amputation. Conclusion: Management of Gustilo Anderson III B open tibial fractures with "fix and shift" technique has resulted in better outcome in terms of skeletal factors (primary fracture union, overall union, and time for union and malunion) and soft tissue factors (wound healing, flap failure, access to secondary procedures, and esthetic appearance) when compared to standard methods adopted earlier. Hence, "fix and shift" could be recommended as one of the treatment modalities for open III B tibial fractures.

Anatomical variation of posterior slope of tibial plateau in adult Eastern Indian population p. 69
Shyamalendu Medda, Rajib Kundu, Sohini Sengupta, Ananda Kisor Pal
Background: Upper surface of the proximal tibial end, tibial plateau, has a slope directed posteroinferiorly relative to the long axis of the middle of the shaft. It has important consideration in surgeries such as knee arthroplasty, high tibial osteotomy, and medical imaging of the knee joint. The aim of the present study was to estimate the tibial plateau angle (TPA) by plain radiograph in the adult Eastern Indian population as during literature review, we were unable to find any study, except one (without specific reference axis), on this variable among the Indian population. Materials and Methods: A sample was taken from adult patients attending the outpatient department of orthopedics of the institute with minor knee problems. Measurement of the TPA was done in the true lateral radiographs of the knee joints of the selected subjects by a standardized method. Results: TPA varied widely from 6° to 24°, with the mean ± standard deviation value 13.6° ±3.5°. Student's unpaired t-test revealed no significant difference of TPA between left and right knees, both in male ( P = 0.748) and female ( P = 0.917) separately and in the entire study population irrespective of gender ( P = 0.768). Comparison of TPA between male (13.3° ± 3.3°) and female (13.9° ± 3.4°) by Student's unpaired t-test showed no sexual dimorphism ( P = 0.248). There were poor correlations of TPA with age and body mass index. Conclusion: The present study described the variations of the TPA in the adult Eastern Indian population (range 6°-24°, mean ± SD 13.6° ± 3.5°, no laterality, no sexual dimorphism, poor correlation with age and BMI). Knowledge of this study could be used in different orthopedic surgeries and imaging technique in or around the knee joint.

Transfibular ankle arthrodesis: A novel method for ankle fusion - A short term retrospective study p. 75
S Muthukumar Balaji, V Selvaraj, Sathish Devadoss, Annamalai Devadoss
Background: Ankle arthrodesis has long been the traditional operative treatment for posttraumatic arthritis, rheumatoid arthritis, infection, neuromuscular conditions, and salvage of failed ankle arthroplasty. It remains the treatment of choice for patients in whom heavy and prolonged activity is anticipated. We present our short term followup study of functional outcome of patients who underwent transfibular ankle arthrodesis for arthritis of ankle due to various indications. Materials and Methods: 29 transfibular ankle arthrodesis in 29 patients performed between April 2009 and April 2014 were included in this study. The mean age was 50 years (range 22-75 years). The outcome analysis with a minimum of 1-year postoperative followup were included. All the patients were assessed with the American Orthopaedic Foot and Ankle Society (AOFAS) Hindfoot scale. Results: All cases of ankle fusions (100%) progressed to solid union in a mean postoperative duration of 3.8 months (range 3-6 months). All patients had sound arthrodesis. The mean followup period was 32.52 months (standard deviation ± 10.34). The mean AOFAS score was 74 (pain score = 32, functional score = 42). We found that twenty patients (68.96%) out of 29, had excellent results, 7 (24.13%) had good, and 2 (6.89%) showed fair results. Conclusion: Transfibular ankle arthrodesis is a simple and effective procedure for ankle arthritis. It achieves a high rate of union and good functional outcome on midterm followup.

Interobserver variability in Pirani clubfoot severity scoring system between the orthopedic surgeons p. 81
Saurabh Jain, Anand Ajmera, Mahendra Solanki, Alok Verma
Background: Congenital talipes equinovarus (clubfoot) is one of the most common congenital pediatric orthopedic foot deformity, which varies in severity and clinical course. Assessment of severity of the club foot deformity is essential to assess the initial severity of deformity, to monitor the progress of treatment, to prognosticate, and to identify early relapse. Pirani's scoring system is most acceptable and popular for club foot deformity assessment because it is simple, quick, cost effective, and easy. Since the scoring system is subjective in nature it has inter- and intra-observer variability, it is widely used. Hence, the interobserver variability between orthopedic surgeons in assessing the club foot severity by Pirani scoring system. Materials and Methods: We assessed the interobserver variability between five orthopedic surgeons of comparable skills, in assessing the club foot severity by Pirani scoring system in 80 feet of 60 children (20 bilateral and 40 unilateral) with club foot deformity. All the five different orthopedic surgeons were familiar with Pirani clubfoot severity scoring and Ponseti cast manipulation, as they had already worked in CTEV clinics for at least 2 months. Each of them independently scored, each foot as per the Pirani clubfoot scoring system and recorded total score (TS), Midfoot score (MFS), Hind foot score (HFS), posterior crease (PC), emptiness of heel (EH), rigidity of equnius (RE), medial crease (MC), curvature of lateral border (CLB), and lateral head of talus (LHT). Interobserver variability was calculated using kappa statistic for each of these signs and was judged as poor (0.00-0.20), fair (0.21-0.40), moderate (0.41-0.60), substantial (0.61-0.80), or almost perfect (0.81-1.00). Results: The mean age was 137 days (range 21-335) days. The mean Pirani score was 3.86. We found the overall consistency to be substantial for overall score (total score kappa - 0.71) and also for midfoot (0.68) and hindfoot (0.66) separately. The consistency was least for the emptiness of heel (kappa - 0.39), and best for rigidity of equnius (kappa - 0.68) and rest of the parameters were moderate (kappa between 0.40 and 0.60). Conclusion: The Pirani scoring system had got substantial reliability in assessing the clubfoot deformity even when the reliability test was extended to five different orthopedic surgeons simultaneously.

Outcome of anatomic locking plate in extraarticular distal humeral shaft fractures p. 86
Deepak Jain, Gurpreet S Goyal, Rajnish Garg, Pankaj Mahindra, Mohammad Yamin, Harpal S Selhi
Background: Extraarticular fractures of distal humerus are challenging injuries to treat because of complex anatomy and fracture patterns. Functional bracing may not provide adequate stability in these injuries and operative treatment with intramedullary nails or conventional plates also has the limitation of inadequate fixation in the short distal fragment. The 3.5 mm precontoured single column locking plate (extraarticular distal humerus plate [EADHP]) has been introduced to overcome this problem. We evaluated the clinical and functional outcomes of treating these fractures with the EADHP. Materials and Methods: 26 patients with extraarticular fractures of distal humerus presenting within 3 weeks of injury between January 2012 and June 2015, were included in this prospective study. Open IIIB and IIIC fractures, nonunions, or those with a history of previous infection in the arm were excluded. Operative fixation was done using the EADHP in all the cases. The time for union, range of motion at shoulder and elbow and secondary procedures were recorded in followup. The shoulder and elbow function was assessed using the University of California Los Angeles (UCLA) shoulder scale and Mayo Elbow Performance Score (MEPS) respectively. Results: There were 21 males and 5 females with mean age of 37.3 years (range 18-72 years). Twenty two (84.6%) cases had complex fracture patterns (AO/OTA Type 12-B and C). The mean time to fracture union was 22.4 weeks (range 16-28 weeks). The mean followup time was 11.6 months, (range 4-24 months). Four patients (15.4%) had failure of cortical screws in the proximal fracture fragment, of which two required revision fixation with bone grafting. Another nonunion was seen following a surgical site infection, which healed after wound lavage and bone grafting. The MEPS (average: 96.1; range 80-100) was excellent in 81% cases (n = 21) and good in 19% cases (n = 5). UCLA score (average: 33.5; range 25-35) was good/excellent in 88.5% cases (n = 23) and fair in 11.5% cases (n = 3). Conclusion: EADHP is a reliable option in treating extraarticular distal humeral fractures as it provides stable fixation with an early return to function.

Distal radius fractures: Minimally invasive plate osteosynthesis with dorsal bicolumnar locking plates fixation p. 93
Alvin Chao-Yu Chen, Ying-Chao Chou, Chun-Ying Cheng
Background: Controversy still exists regarding the current treatment modalities for unstable distal radius fractures. There are yet few articles investigating the efficacy of bicolumnar dorsal plating technique, which is designed to minimize tissue dissection while providing sufficiently secure fixation. A clinical study was performed to evaluate the feasibility of the minimally invasive plate osteosynthesis (MIPO) technique using a modified dorsal approach for the treatment of distal radius fractures. Materials and Methods: Thirty patients with unilateral distal radius fracture who underwent bicolumnar plate fixation with a minimally invasive dorsal approach between September 2008 and December 2010 were included in this retrospective study. Twenty four patients (8 men and 16 women) with a mean age of 53 years (range 18-85 years) were available for followup of at least 1 year or more were included in final study. Herein, we report the functional radiological outcomes of the study. There were three cases of AO Type A fracture, five cases of AO Type B fracture, and 16 cases of AO Type C fracture. Results: The union was achieved in all the patients. The functional results at one-year followup, assessed using the modified Gartland and Werley scoring system, were excellent in 14 patients, good in seven patients, and fair in three patients. The average correction of deformity was 4.1 mm for radial height, 7.6° for radial inclination, and 20.7° for volar tilt. Conclusions: MIPO with a dorsal approach is a feasible option for the management of displaced distal radius fractures and can result in favorable surgical outcomes.

"Quadrangular-construct" modification of Sauve-Kapandji procedure p. 99
Ravi K Gupta, Ashwani Soni, Anubhav Malhotra, Gladson D Masih
Background: Subluxation of ulna in distal radioulnar joint disorders causes pain on motion, loss of grip strength, and a restriction of forearm rotation. Several procedures have been described to salvage DRUJ disorders including the Darrach procedure, the matched distal ulnar resection, the hemiresection interposition arthroplasty (Bowers procedure) and the Sauve-Kapandji (S-K) procedure. All these procedures are associated with either loss of grip, pain over proximal ulnar stump or instability. We describe our modification of S-K procedure with good functional outcome. Materials and Methods: Twenty patients, 12 male and 8 female, underwent S-K procedure, with our modification, were included in this study. Patients were evaluated preoperatively, postoperatively, and on followup visits using Modified Mayo Wrist Score and wrist radiographs. Average followup period was 34.55 months (range 24-64 months). Results: Excellent results were found in one patient, good in 15 patients, and fair in four patients. Mean Modified Mayo Wrist Score improved from 32 to 79.75, which was statistically significant. Conclusions: Our modification of S-K procedure provides good functional outcome with stable ulnar stump and without significant procedure-related complications.

Pseudotumor due to metallosis after total elbow arthroplasty p. 103
Roberto Rotini, Graziano Bettelli, Michele Cavaciocchi, Lucia Savarino
The incidence of primary total elbow arthroplasty (TEA) in young patients is increasing. The indications for revision surgery are also rising. Here, we report a rare case of pseudotumor detected in a patient 16 years after TEA. Intraoperative findings revealed a necrotic mass characterized by a conspicuous metallosis in the soft tissues around the prosthesis, which caused ulnar nerve dislocation. Due to this anatomical change, a lesion of the nerve was accidentally produced during revision surgery. The case report emphasizes that the indications for elbow replacement, as well as the patient education about the permanent physical limitations, should be carefully considered. Moreover, the high risks of complications related to the revision procedure and pseudotumor removal need to be addressed before surgery. The technique should be done carefully and a preliminary thorough imaging should be performed, since a newly formed mass can cause significant distortion of the anatomy.

Vanishing bone disease of chest wall and spine with kyphoscoliosis and neurological deficit: A case report and review of literature p. 107
Sudhir Kumar Srivastava, Rishi Anil Aggarwal, Pradip Sharad Nemade, Sunil Krishna Bhoale
Vanishing bone disease is an extremely rare disorder of unknown etiology characterized by idiopathic osteolysis of bone. We describe a case of vanishing bone disease of chest wall and spine with kyphoscoliosis and neurological deficit. A 17-year-old male presented with gradually progressive deformity of back and dorsal compressive myelopathy with nonambulatory power in lower limbs. Radiographs revealed absent 4 th-7 th ribs on the right side with dorsal kyphoscoliosis and severe canal narrowing at the apex. The patient was given localized radiotherapy and started on a monthly infusion of 4 mg zoledronic acid. Posterior instrumented fusion with anterior reconstruction via posterolateral approach was performed. The patient had a complete neurological recovery at 5 weeks following surgery. At 1 year, anterior nonunion was noted for which transthoracic tricortical bone grafting was done. Bone graft from the patient's mother was used both times. At 7 months following anterior grafting, the alignment was maintained and the patient was asymptomatic; however, fusion at graft-host interface was not achieved. Bisphosphonates and radiotherapy were successful in halting the progress of osteolysis.
