Effect of chronic heavy tobacco smoking on ankle fracture healing.

INTRODUCTION: Tobacco smoking is linked to an elevated risk of osteomyelitis and delayed healing in long bone fractures. However, the impact of smoking on bone union and soft tissue recovery following ankle fractures remains unclear. This study presents a retrospective comparative analysis evaluating the effects of chronic heavy tobacco smoking on the healing process and outcomes of ankle fractures after surgical interventions. MATERIALS AND METHODS: We examined 220 consecutive cases of chronic heavy smokers (CHS) with closed ankle fractures who were referred to our unit for further treatment. A control group, consisting of 220 age- and sex-matched individuals (non-smokers with closed ankle fractures), was identified for comparative analysis. We collected clinical data, including pre-existing comorbidities, Lauge-Hansen fracture classification, necessity for surgery, and the surgical procedures performed. The primary outcomes investigated were the time required for fracture union and wound healing. Secondary outcomes included postoperative complications such as prolonged pain, bleeding, swelling, infection, compartment syndrome, and neurovascular impairment, as well as the incidence of delayed union, non-union, and the need for further intervention. Both cohorts were monitored for a minimum of 24 months. RESULTS: Our analysis revealed that the surgical cohort of chronic heavy smokers exhibited a statistically significant delay in fracture union compared to both the conservatively managed smokers and the control group. Further scrutiny of the surgical cohort of chronic smokers indicated a significant correlation between smoking and extended postoperative pain duration, persistent swelling at the fracture site, and both superficial and deep wound infections. Additionally, these patients experienced delays in both fracture union and wound healing when compared to the control group. Similarly, the conservatively managed chronic smokers showed a marginal increase in the incidence of post-injury pain duration, extended swelling at the fracture site, and delayed union compared to the control group. CONCLUSION: Patients who are chronic heavy smokers and require surgical intervention for ankle fractures should be made aware of their increased risk for delayed fracture union and poor wound healing. Orthopedic surgeons should proactively encourage these patients to participate in smoking cessation programs.

Complications of laser and light-based devices therapy in patients with skin of color.

Lasers and light-based devices are indispensable to an aesthetic dermatology practice. The growing popularity of lasers has been matched by a sharp increase in the incidence of complications. The Indian skin with its high melanin content is more prone to injury and careful setting of laser parameters, early detection of complications and immediate therapy are vital to avoiding permanent sequelae. We review the various complications that occur during laser procedures and their management.

Occurrence of major complications after cochlear implant surgery in Ireland.

OBJECTIVES: Cochlear implantation (CI) is considered an effective and relatively safe procedure for patients with severe-profound hearing loss. However, severe complications are reported in several studies. The purpose of this study was to report the frequency and management of major complications following CI surgery at the National CI Programme (NCIP) in Ireland. METHODS: Major complications were defined according to the classification of Hansen et al. 2010. The medical records of 1017 patients undergoing CI between 1995 and 2016 were analyzed retrospectively for major complications. In addition, radiological and intraoperative findings as well as therapeutic management of all patients with a major complication were reviewed. RESULTS: Altogether, 1017 patients underwent 1266 CI surgeries. The median follow-up of all CI surgeries was 44 months. The total number of major complications identified was 21 which corresponds to an overall rate of 1.7%. The majority of major complication (71%) occurred at least one week after surgery. The most common major complications were internal receiver/stimulator protrusion and migration (6/21), followed by migration of the electrode array (4/21) and recurrent otitis media requiring re-implantation (4/21). All patients with major complications required additional surgery, with reimplantation necessary in 19 patients (90%). DISCUSSION: CI surgery is a safe surgical procedure for hearing rehabilitation associated with a low rate of severe complications. However, major complications can occur many years after surgery, making revision surgery necessary. CONCLUSION: Long-term follow-up is necessary for the early identification of complications to facilitate appropriate care.

Nonoperative Versus Operative Treatment of Displaced Ankle Fractures in Diabetics.

BACKGROUND: Diabetes is a risk factor for complications related to displaced ankle fractures. Limited literature exists comparing complication rates in nonoperative versus operative treatment of displaced ankle fractures in diabetics. No study has highlighted the natural history of nonoperative treatment of displaced ankle fractures in diabetics. METHODS: We retrospectively reviewed all adult ankle fractures from September 2011 through December 2014. Inclusion was limited to ambulatory adults (>18 years) with closed, displaced (widened mortise) ankle fractures with diabetes mellitus. Nonoperative treatment consisted of closed reduction and casting. Fractures were classified according to the Lauge-Hansen and AO-Weber classification systems. All operative fractures underwent open reduction internal fixation (ORIF) within 3 weeks of injury. Functional outcomes and complication rates were compared. Of 28 displaced diabetic ankle fractures, 20 were treated nonoperatively (closed reduction and casting) and 8 operatively (ORIF within 3 weeks of injury). Mean follow-up was 7 months (range 3-18 months). RESULTS: Age, insulin-dependent diabetes, and AO type B fracture rate were similar in nonoperative and operative cohorts, but fracture dislocation rate was significantly higher among operative fractures (87.5% vs 40%; P = .04). Nonoperative treatment was associated with a 21-fold increased odds of complication compared with operative treatment (75% vs 12.5%, OR 21.0, P = .004). Complication rate following unintended ORIF for persistent nonunion or malunion in nonoperatively treated patients was significantly greater compared with immediate ORIF (100% vs 12.5%, P = .005). CONCLUSION: Nonoperative treatment of displaced diabetic ankle fractures was associated with unacceptably high complication rates when compared to operative treatment. LEVEL OF EVIDENCE: Level III, retrospective comparative series.

Worldwide experience with the robotic navigation system in catheter ablation of atrial fibrillation: methodology, efficacy and safety.

INTRODUCTION: The Hansen Robotic system has been utilized in ablation procedures for atrial fibrillation (AF). However, because of the lack of tactile feedback and the rigidity of the robotic sheath, this approach could result in higher risk of complications. This worldwide survey reports a multicenter experience on the methodology, efficacy, and safety of the Hansen system in AF ablations. METHODS AND RESULTS: A questionnaire addressing questions on patient's demographics, procedural parameters, ablation success rate and safety information was sent to all centers where more than 50 robotic AF ablation cases have been performed. From June 2007 to December 2009, 1,728 procedures were performed at 12 centers utilizing the Hansen robotic navigation technology. The overall complication rate was 4.7% and the success rate was 67.1% after 18 ± 4 months of follow-up. In 5 low volume centers there appeared to be a learning curve of about 50 cases (complication rate 11.2% for the first 50 cases vs 3.7% for the 51-100 cases; P = 0.044) and a trend showing a decrease of complication rate with increasing case volume. However, in the remaining 7 centers no learning curve was present and the complication rate was stable over time (3.7% for the first 50 cases vs 3.6% for the 51st case thereafter; P = 0.942). CONCLUSION: The Hansen robotic system can be used for AF ablation safely. In low volume centers, there appeared to be a learning curve of the first 50 cases after which the complication rate decreased. With a higher case volume, the success rate increased.

Changing trends in hair restoration surgery.

Androgenetic alopecia is an important and common cause for baldness. Despite recent advances, the drug therapy of this condition remains unsatisfactory. Surgical hair restoration is the only permanent method of treating this condition. Introduction of recent techniques such as follicular unit transplantation have improved the cosmetic results and patient satisfaction. This article discusses the latest trends in hair restoration surgery.

A rational approach to nasal reconstruction in leprosy.

Destruction of the nasal septum and nasal bones by Mycobacterium leprae and subsequent infection is still seen regularly in leprosy endemic areas. The social stigma associated with this deformity is significant. Many different procedures have been developed to reconstruct the nose. Patients operated on at Anandaban Hospital and the Green Pastures Hospital and Rehabilitation Center between 1986 and 2001 were reviewed. There were 48 patients with an average age of 47 years. Five deformities were mild, 22 were moderate, 13 were severe, and eight were not graded. Bone grafting with nasolabial skin flaps was performed in 14 cases, bone grafting alone was performed in 10 cases, flaps alone were performed in seven cases, and cartilage grafting was performed in 10 cases. In three patients, a prosthesis was inserted, and in three patients a gull-wing forehead flap was performed. Overall, excellent or good cosmetic results were obtained in 83 percent of cases. Grafting with conchal cartilage was associated with the best cosmetic results and had minimal complications. Bone grafting with or without nasolabial flaps was associated with a 50 percent complication rate of infection or graft resorption. In mild to moderate deformities, cartilage grafting is recommended; for more severe deformities, bone grafting with bony fixation and skin flaps is recommended. Perioperative antibiotics must be used, and these procedures should be performed by an experienced surgeon. In very severe cases with skin deficiency, reconstruction with a forehead flap gives good results.

Comparative evaluation of effectiveness of different motor muscles in modified lasso procedure for correction of finger clawing.

A retrospective study was carried out to compare the effectiveness of different muscles as motors in modified lasso procedures for correction of finger clawing in leprosy. It was observed that palmaris longus and extensor carpi radialis longus were more suitable than the flexor digitorum superficialis. In some patients, removal of superficialis is associated with complications which could not be predicted before surgery. Extensor carpi radialis longus has advantages over palmaris longus in selected cases.

Location of the extracranial extent of leprous facial nerve pathology may allow leprous facial palsy to be reanimated by free muscle transfer.

Leprosy is a mycobacterial nerve and skin infection, which can be eradicated by antibiotics. Some patients affected by leprosy, once cured, have residual nerve impairment with paralysis and sensory neuropathy. A series of patients with facial nerve paralysis, investigated using clinical, histological and electrophysiological techniques, demonstrated that the nerve pathology was distal to the section of main trunk prior to its bifurcation. Facial reanimation was achieved with a free gracilis-muscle transfer, coapting its motor nerve to the ipsilateral facial nerve trunk proximal to the site of the leprosy pathology, with a moderate clinical result.

[How does one treat the osteitis and osteoarthritis of the extremities in older leprosy patients using granulated table sugar?]. / Comment guérir les ostéites et ostéo-arthrites des extrémités des anciens malades de la lèpre par le sucre cristallisé alimentaire?

A common problem of osteitis and septic arthritis is the recurrent bone infection after surgical debridement, a problem frequently encountered in patients with sequela leprosy. In these cases the authors propose the use of an ancient method of post surgical wound care based on the treatment with ordinary granulated sugar. The hyperosmolar climate created this way in the wounds inhibits the bacterial growth, enhances bacterial death and therefore permits the growth of granulation tissue in order to recover the debrided nude bones. At ILAD (Leprosy Institute of Dakar), 36 osteitis and septic arthritis were treated and healed during the last 2 years from March 1995 to March 1997 using this technic. All the wounds healed in the mean-time of 44 days. Only two of them needed a second debridement and healed afterwards. Up to now the method using ordinary sugar was applied in the treatment of infected wounds, eschars and postsurgical infections. Our experience shows that it also can be indicated to treat bone infections. This method is easy to apply also under often difficult field conditions and is very cheap.

The pattern of cataract and the postoperative outcome of cataract extraction in Ethiopian leprosy patients as compared to nonleprosy patients.

Cataract is a blinding disease occurring all over the world. One of the causes of cataract is leprosy. Sixty leprosy and 100 nonleprosy patients were assessed and underwent intracapsular cataract extraction. Leprosy patients with cataract were much younger than nonleprosy patients. The leprosy group had a significantly higher rate of complications and this was seen more in paucibacillary cases. There was a higher rate of visual disability in the leprosy group than in the nonleprosy group. Cataract was seen in younger patients in the leprosy group. This raised the possibility of leprosy being the cause of the cataract. The leprosy group consisted mostly of multibacillary cases, however unlike in other studies the rate of complications tended to be higher in the paucibacillary group. There were no preoperative findings that correlated with a low postoperative intraocular pressure.

The use of the Hansen-Street intramedullary nail in midshaft fractures of the femur.

A retrospective study was conducted on 75 consecutive femoral midshaft fractures treated with intramedullary nailing using the solid-diamond-shape Hansen-Street nail with an open technique. The average age of patients was 32.5 years. Road accidents accounted for 43 cases. The average operative time was 40 minutes. There were two systemic complications. No infection occurred. Fifty-six cases could be gathered for this study, with an average follow-up of 5 years; 19 were followed for at least 6 months. At 4 months, all the fractures were united except one. The average time to sound bony union was 4 months. There was no residual deformity in varus-valgus or in the sagittal plane. Malrotation was rare and did not exceed 5 degrees. Shortening of 2 cm was found in 3 patients where the fracture was comminuted. All followed patients returned to regular daily function. The use of the Hansen-Street nail in an open procedure is an accurate method for anatomic reduction. As opposed to closed techniques, the procedure proved in our hands to be simple and quick, without undue exposure to radiation of the surgical team, and without such other complications as nerve complications due to traction. The procedure with this device is indicated for mid-third fractures of the femoral shaft only.

Early use of the Brooker-Wills interlocking intramedullary nail (BWIIN) for femoral shaft fractures in acute trauma patients.

During a 33-month period, 40 multiply injured patients underwent 43 Brooker-Wills interlocking intramedullary nailings (BWIIN) for femur fractures in the setting of a Level I trauma unit. There were 12 open fractures (28%), 66% of the closed fractures underwent BWIIN within the first 24 hours of injury, and 33 fractures (77%) had comminution of Winquist-Hansen Type II or greater, and either static or dynamic locking techniques were used in 38 (88%) of the cases. There were three intraoperative technical problems. The estimated blood loss and operative times were consistent with other reported series for interlocking nailing techniques. The average followup was 65 weeks. Only one fracture went on to nonunion. There were no problems with angulation or rotation. One patient had 1.5 cm of shortening. There were four major (9%) and four minor (9%) complications. Rod removal was successful in 17 of 18 cases. Mechanical failure (deformation and/or fracture) of the proximal end of the rod was found in four (22%) of the extracted nails and caused failure of removal in one. The Brooker-Wills nail is a versatile device which can be used to treat complex fractures of the entire femoral shaft in acutely injured patients.

Observations of tarsal disintegration in the cases operated for foot-drop.

Fifty cases operated for foot-drop during the years 1971-82 were called for follow-up. Out of fifty, twenty cases were reported to the hospital. Three cases among the twenty were found to have changes of tarsal disintegration. The changes were found more confined to the talo-navicular junction. X-ray changes both in non-weight and weight bearing were studied. Their line drawings (tracings from actual radiograph) are presented. It is concluded that due attention should be given to the pre-operative evaluation, operative procedure used and post-operative management particularly the weight-bearing and proper footwear.
