PRP appeared to enable biological healing of the lesion, whereas CS appeared to provide short-term, symptomatic relief but resulted in tendon degeneration.

A few cases of fire in the operating room are reported in the literature. The factors that may initiate these fires are many and include alcohol based surgical prep solutions, electrosurgical equipment, flammable drapes etc. We are reporting a case of fire in the operating room while operating on a patient with burst fracture C6 vertebra with quadriplegia. The cause of the fire was due to incomplete drying of the covering drapes with an alcohol based surgical prep solution. This paper discusses potential preventive measures to minimize the incidence of fire in the operating room. Case presentationA 25 years old male patient with burst fracture of C6 vertebra with quadriplegia was taken to the operating room for anterior decompression with fusion. He was positioned supine on the operating table. The neck, shoulder region and the upper part of chest up-to the level of nipples was shaved. General anesthesia was induced and the patient was intubated for intra-operative ventilation using closed circuit. The neck, shoulder and chest region was painted with Cutasept R (contains Benzalkonium chloride and Isoproponol 63%). The surgical site was draped with cotton sheets. A longitudinal incision was given along the anterior border of sternomastoid and the subcutaneous tissue was exposed. Electrocautery was then brought into the field for deeper dissection. Flames were noticed around the surgical site immediately after the activation of the electrocautery. The flames were spread over the entire surgical field corresponding to the area prepared with Cutasept R . The drapes were immediately removed and the electrocautery was switched off. The fire was rapidly extinguished within seconds. The patient suffered minor burns in the neck and chest region (first degree) and recovery was uneventful. DiscussionOperating room fires are uncommon. Studies by Emergency Care Research Institute have shown that approximately 100 operating room fires occur every year with 10-20 of these events deemed "serious" and two directly resulting in death. Nearly 70% of these fires are related to the use of electro surgical equipment. Furthermore, in 72% of cases, an oxygen-enriched atmosphere has been shown to have contributed to the fire. It has also been noticed that there is a significant risk of fire when alcohol based surgical prep solutions are used for skin preparation [1][2][3]. The fact that alcohol based antiseptic solutions can provide fuel for surgical fire has been demonstrated both by reports of surgical fires and laboratory studies [4,5].The fire triangle is a useful construct that describes the three elements necessary for initiation of a fire i.e., heat, fuel and an oxidizer. In the case of operating room fires, an electrosurgical unit most often provides heat to ignite

Purpose Medial pivot (MP) total knee arthroplasty (TKA) aims to restore native knee kinematics due to highly conforming medial tibio-femoral articulation with survival comparable to contemporary knee designs. Posterior stabilized (PS) TKAs use cam-post mechanism to restore native femoral rollback. However, there is conlicting evidence regarding the reported patient satisfaction with MP TKA designs when compared to PS TKAs. The primary aim of this study is to compare the patient satisfaction between MP and PS TKA and the secondary aim is to establish potential reasons behind any diferences in the outcomes noted between these two design philosophies. Methods In this IRB-approved single surgeon, single centre prospective RCT, 53 patients (mean age 62 years, 42 women) with comparable bilateral end-stage knee arthritis undergoing simultaneous bilateral TKA were randomized to receive MP TKA in one knee and PS TKA in the contralateral knee. At 4 years post-surgery, all patients were assessed using Knee Society Score (KSS)-Satisfaction and -Expectation scores, and Oxford Knee Score (OKS). In addition, all the patients underwent standardized radiological and in vivo kinematic assessment. Results Patients were more satisied with the MP TKA as compared to PS TKA: mean KSS-Satisfaction [34.5 ± 3.05 in MP and 31.7 ± 3.16 in PS TKAs (p < 0.0001)] and mean KSS-Expectation scores [12.5 ± 1.39 in MP TKAs and 11.2 ± 1.41 in PS TKAs (p < 0.0001)]. No signiicant diference was noted in any other clinical outcomes. The in vivo kinematics of MP TKAs was signiicantly better than those of PS TKAs. Conclusion MP TKAs provide superior patient satisfaction and patient expectations as compared to PS TKA. This may be related to better replication of natural knee kinematics with MP TKA. Level of evidence I.

Background The relationship of the radial nerve is described with various osseous landmarks, but such relationships may be disturbed in the setting of humerus shaft fractures. Alternative landmarks would be helpful to more consistently and reliably allow the surgeon to locate the radial nerve during the posterior approach to the arm. Questions/purposes We investigated the relationship of the radial nerve with the apex of triceps aponeurosis, and describe a technique to locate the nerve. Materials and MethodsWe performed dissections of 10 cadavers and gathered surgical details of 60 patients (30 patients and 30 control patients) during the posterior approach of the humerus. We measured the distance of the radial nerve from the apex of the triceps aponeurosis along the long axis of the humerus in cadaveric dissections and patients. This distance was correlated with the height and arm length. For all patients, we recorded time until first observation of the radial nerve, blood loss, and postoperative radial nerve function. Results The mean distance of the radial nerve from the apex of the triceps aponeurosis was 2.5 cm, which correlated with the patients' height and arm length. The mean time until the first observation of the radial nerve from beginning the skin incision was 6 minutes, as compared with 16 minutes in the control group. Mean blood loss was 188 mL and 237 mL, respectively. With the numbers available, we observed no difference in the incidence of patients with postoperative nerve palsy: none in the study group and three in the control group. Conclusion The apex of the triceps aponeurosis appears to be a useful anatomic landmark for localization of the radial nerve during the posterior approach to the humerus. IntroductionOwing to an increase in high-energy trauma cases, the incidence of fractures of the humerus diaphysis is increasing. Operative treatment of humeral fractures, especially the distal third region, chronic osteomyelitis of the distal third of the humerus requiring sequestrectomy and radial nerve palsy requiring exploration, usually requires a posterior approach to the humerus. This approach causes iatrogenic radial nerve injury in 0% to Each author certifies that he has no commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.

Background:The venous stasis of soleal vein during surgery may be an important factor in the development of deep vein thrombosis (DVT). The stimulation of calf muscle during surgery may help in preventing DVT. The present study is conducted to evaluate the role of peroperative calf muscle electrostimulation in prevention of DVT in patients undergoing surgeries around the hip joint.Materials and Methods:The study comprised 200 patients undergoing surgeries around the hip joint. The patients having risk factors (such as previous myocardial infarction, malignancies, paraplegia or lower limb monoplegia, previous history of DVT or varicose veins, etc.) for the development of DVT were excluded. They were randomized into two groups: 100 cases were given peroperative calf muscle electrostimulation for DVT prophylaxis (Group A) and the remaining 100 patients were taken as controls without any prophylaxis (Group B). The color Doppler ultrasound was performed to exclude pre-existing DVT and on 7th day postoperative to find out the incidence of DVT in both the groups.Results:Two patients among Group A and six patients among Group B demonstrated DVT on ultrasonography, but the difference was not found to be statistically significant (P=0.279). None of the patients had any clinical evidence of DVT.Conclusion:The role of peroperative calf muscle electrostimulation for DVT prophylaxis remains controversial. The risk of developing DVT in patients undergoing surgeries around the hip joint is very less in patients analysed in our series.

Little finger metacarpal fractures are the most common type of metacarpal fractures and the treatment is quite variable as it is a multifactorial entity comprised of subcapital, metacarpal shaft and base fractures. These fractures are common presentations in the fracture clinics and the general orthopaedic surgeons treat them until a complex case warrants specific decision making by a hand surgeon. The management of many of these fractures is still a matter of debate and differ widely in the various parts of the United Kingdom. The aim of this study was to investigate the current practice of little finger metacarpal fractures among upper limb surgeons in the UK. We conducted an online survey among 278 upper limb orthopaedic specialist surgeons throughout the UK. Our response rate was 58%. There are various factors which dictate the treatment as suggested by these respondent upper limb consultants. For example, for fifth metacarpal neck fractures, it was generally recognised that 43% of upper limb surgeons prefer neighbour strapping alone for non-operative management of little finger metacarpal fractures. For little finger metacarpal shaft fractures, 39.3% of surgeons suggested that they would contemplate intervention, i.e. manipulation under anaesthesia/surgery if beyond 30° of volar angulation is present. For little finger metacarpal neck fractures, 33.7% would only consider surgical intervention beyond 60° of volar angulation. 91.6% of upper limb specialists agreed that they would operate on little finger metacarpal base fractures only if it was a fracture dislocation, while 71.8% suggested that they would proceed to operate on even a pure dislocation. We have illustrated the various permutations and combinations of these fractures with the results of our survey in this article in detail. The vast majority of metacarpal bone fractures are stable and treated conservatively. The different types of injury patterns must be recognised by the orthopaedic surgeons and appropriate treatment then should be executed to serve the patient optimally in due course.

Habitual dislocation of patella is a condition where the patella dislocates whenever the knee is flexed and spontaneously relocates with extension of the knee. It is also termed as obligatory dislocation as the patella dislocates completely with each flexion and extension cycle of the knee and the patient has no control over the patella dislocating as he or she moves the knee(1). It usually presents after the child starts to walk, and is often well tolerated in children, if it is not painful. However it may present in childhood with dysfunction and instability. Very little literature is available on habitual dislocation of patella as most of the studies have combined cases of recurrent dislocation with habitual dislocation. Many different surgical techniques have been described in the literature for the treatment of habitual dislocation of patella. No single procedure is fully effective in the surgical treatment of habitual dislocation of patella and a combination of procedures is recommended.
