Full Endoscopic Discectomy Using Transforaminal Endoscopic Spine System Technique: A Mini Review of Complications

Background:

Full Endoscopic Discectomy (FED) is a minimally invasive technique for the treatment of Lumbar Disk Herniation (LDH) with increasing popularity among surgeons in the recent years. This alternative to conventional procedures surgical approach is generally a safe and efficient technique possessing many advantages such as less soft tissue trauma, preservation of dorsal musculature, and reduced perioperative morbidity and rapid recovery. However, FED is associated with a number of complications such as postoperative dysesthesia, nerve root injury, and dural tears.

Methods:

Α search of PubMed, Google Scholar and Scopus electronic databases was used to revised the literature on complications of full endoscopic discectomy using transforaminal endoscopic spine system technique

Conclusion:

In this review complications associated with FED are analyzed, emphasizing on the potential beneficial role of Transforaminal Endoscopic Spine System (TESSYS) technique in reducing their frequency.

Update on diagnosis and management of cuboid fractures

Cuboid fractures due to the particular bone anatomy and its protected location in the midfoot are rare, and they are usually associated with complex injuries of the foot. Clinical examination to diagnose these fractures should be detailed and the differential diagnosis, especially in the case of vague symptoms, should include the exclusion of all lateral foot pain causes. Conventional radiographs do not always reveal occult fractures, which can be under diagnosed especially in children. In this case, further investigation including magnetic resonance imaging or scintigraphy may be required. The treatment of these injuries depends on the particular fracture characteristics. Non-displaced isolated fractures of the cuboid bone can be effectively treated conservatively by immobilization and by avoiding weight bearing on the injured leg. In the case of shortening of the lateral column > 3 mm or articular displacement > 1 mm, surgical management of the fracture is mandatory in order to avoid negative biomechanical and functional consequences for the foot and adverse effects such as arthritis and stiffness as well as painful gait. In this review, an update on diagnosis and management of cuboid fractures is presented.

An Epidemiological Study of Non-specific Low Back Pain in Non-professional Female Greek Classic Ballet Dancers

AIM

Epidemiological study of the incidence of mechanical low back pain (LBP) in non-professional female Greek classic ballet dancers over a year and therapeutic interventions required to address symptoms.

MATERIALS AND METHODS

Forty-six female classic ballet dancers members of preprofessional schools, aged 16-37 years (mean 28.8 ±5.44 yrs) practicing and training in classic dance for 6-40 hours/week (mean 10.8±6.68) and 2-27 years experience (mean 11.9±4.20 yrs) participated in an epidemiological study concerning the incidence of LBP episodes within the last year, the treatment they received, as well as the period of absence of training and performance due to LBP. A selfadministered questionnaire was employed. Information regarding incidence, duration, and intensity of mechanical low back pain was gathered as well as length of time away from practice or performance. A secondary aim was to investigate the type of conservative treatment that participants in this study received.

RESULTS

Thirty-one (67.4%) participants in the study experienced 1-10 (mean 3.26±1.7) episodes of mechanical LBP in the previous 12 months. They had to refrain from dancing activities from 2 to 90 days (mean 16.9±16.22). Twenty one of the participants received some kind of conservative treatment.

CONCLUSION

The incidence of LBP was found to be high among Greek amateur classic ballet dancers resulting in absence from dancing activities for a considerable length of time and raising the need for therapeutic intervention for a considerable percentage of the studied population. Effective prevention strategies of LBP are of vital importance, particularly in younger dancers.

Transforaminal Percutaneous Endoscopic Discectomy using Transforaminal Endoscopic Spine System technique: Pitfalls that a beginner should avoid

Transforaminal Percutaneous Endoscopic Discectomy (TPED) is a minimally invasive technique mainly used for the treatment of lumbar disc herniation from a lateral approach. Performed under local anesthesia, TPED has been proven to be a safe and effective technique which has been also associated with shorter rehabilitation period, reduced blood loss, trauma, and scar tissue compared to conventional procedures. However, the procedure should be performed by a spine surgeon experienced in the specific technique and capable of recognizing or avoiding various challenging conditions. In this review, pitfalls that a novice surgeon has to be mindful of, are reported and analyzed.

Synthesis of evidence for the treatment of intersection syndrome

Intersection syndrome is a rare sports overuse injury occurring through friction at the intersection of the first and second compartment of the forearm. Differential diagnosis must be carefully made, especially from De Quervain tendonsynovitis. Clinical examination provides with the necessary information for diagnosis, still magnetic resonance imaging scans and ultrasonography may assist in diagnosis. Treatment consists mainly of rest, use of a thumb spica splint, analgetic and oral nonsteroidal anti-inflammatory drugs and after 2-3 wk progressive stretching and muscle strengthening. Should symptoms persist beyond this time, corticosteroid injections adjacent to the site of injury may be useful. In refractory cases, surgical intervention is warranted.

Osteitis pubis in elite athletes: Diagnostic and therapeutic approach

Osteitis pubis (OP) is a debilitating overuse syndrome characterizing by pelvic pain and local tenderness over the pubic symphysis commonly encountered in athletes often involved in kicking, twisting and cutting activities in sports such as soccer and rugby and to a lesser degree distance running. It is a common source of groin pain in elite athletes attributable to pubis sympysis instability as the result of microtrauma caused by repetitive muscle strains on pubic bones. Diagnosis is based mainly on detailed sports history and a meticulous clinical examination, although occasionally is difficult to distinguish this nosological entity from other pathologies affecting the involved area which may occur concomitantly in the same patient. Radiologic examinations such as plain radiographs, magnetic resonance imaging and 3 phase bone isotope scanning may be helpful to differentiate from other clinical entities with similar clinical presentation. Most cases respond well to conservative treatment which includes several physical modalities and especially a progressive rehabilitation programmed individualized to each one of patients diagnosed with OP. Local injection therapies have been also been proposed as a non-operative therapeutic option for the efficient management of these patients. In refractory cases, surgical therapeutic strategies are warranted. These include several open or minimally invasive surgical interventions such as arthroscopic or open symphysis curettage, wedge or total resection of pubic sympysis, polypropylene mesh placement and pubic fusion. In this review a critical analysis of OP in elite athletes is performed with special focus on current concepts of diagnosis and management of this source of athletic groin pain.

Complications following autologous bone graft harvesting from the iliac crest and using the RIA: a systematic review

Bone grafting is a commonly performed surgical procedure to augment bone regeneration in a variety of cases in orthopaedic and maxillofacial surgery. Autologous bone graft remains to be the 'gold standard' and the iliac crest to be the most common harvesting site. The intramedullary canal of long bones represents another potential site for large volume of autologous bone graft harvesting and is recently being used as an alternative donor site. However, harvesting of autologous bone graft is associated with morbidity and a number of complications. The aim of this systematic review was to collect and summarise the existing data on reported complications after harvesting autologous bone from the iliac crest (anterior and posterior) and the long bone intramedullary canal using the RIA device. We searched the PubMed Medline and Ovid Medline databases, from January 1990 to October 2010, to retrieve all relevant articles. A total of 92 articles (6682 patients) were included in the analysis. Overall, the complication rate following RIA was 6% (14 complications in 233 patients) and 19.37% after iliac crest bone graft harvesting (1249 complications in 6449 patients). The rate of each of the reported complications was assessed and, when the donor site was properly documented, comparison within the anterior and posterior iliac crest donor sites was performed. Although the difference of the overall morbidity rates between the two harvesting sites was not statistically significant (p=0.71); the rates of certain complications were found to significantly differ when anterior or posterior iliac crest was used. The rates of infection (p=0.016), haematoma formation (p=0.002), fracture (p=0.017), and hyperthrophic scar (p=0.017) were significantly higher when the donor site was the anterior iliac crest compared to the posterior iliac crest; whereas the rates of chronic donor site pain (p=0.004) and sensory disturbances (p=0.003) were significantly lower. The incidence of bone graft harvesting related complications can be reduced further if certain principles are followed depending on the performed harvesting methods; but overall the use of RIA device as harvesting method seems a promising alternative with a low complication rate.

Evidence-based evaluation and current practice of non-operative treatment strategies for lumbar stenosis

OBJECTIVE

A number of non-operative treatment protocols have been proposed in the literature for lumbar stenosis. However, the available primary research describes inadequately the employed protocol. This causes difficulties in distinguishing which interventions are more effective in reducing symptoms.

METHODS

We reviewed existing studies in order to promote the construction of an evidence-based strategy for non-operative treatment rehabilitation of lumbar stenosis patients. Randomized controlled trials describing insufficiently the non-operative treatment rehabilitation protocols were excluded since the results may not direct this review towards a favorable treatment plan.

RESULTS

A protocol has been outlined to inform the clinician and to elucidate the effectiveness of non-operative treatment through randomized controlled trials. The results of this study indicate that a comprehensive exercise and manual therapy protocol is more effective in reducing symptoms than a less intensive exercise program.

CONCLUSIONS

A comprehensive non-operative treatment comprising of flexion exercises, manual therapy and treadmill exercises appears to be more beneficial in reducing symptoms than a less vigorous program comprising of flexion exercises, treadmill training and home exercise.

Knee proprioception following ACL reconstruction; a prospective trial comparing hamstrings with bone-patellar tendon-bone autograft

We prospectively studied knee proprioception following ACL reconstruction in 40 patients (34 men and six women; mean age 31 years). The patients were allocated into two equal groups; group A underwent reconstruction using hamstrings autograft, and group B underwent reconstruction using bone-patellar tendon-bone autograft. Proprioception was assessed in flexion and extension by the joint position sense (JPS) at 15°, 45° and 75°, and time threshold to detection of passive motion (TTDPM) at 15° and 45°, preoperatively and at 3, 6 and 12 months postoperatively. The contralateral healthy knee was used as internal control. No statistical difference was found between the ACL-operated and the contralateral knees in JPS 15°, 45° and 75° at 6 and 12 months, in both study groups. No statistical difference was found between the ACL-operated and the contralateral knees in TTDPM 15° at 6 and 12 months, nor regarding TTDPM 45° at 3, 6 and 12 months, in group A. No statistical difference was found in JPS and TTDPM between the two grafts, at any time period. Knee proprioception returned to normal with ACL reconstruction at 6 months postoperatively, without any statistically significant difference between the autografts used.

Treatment and outcomes of pelvic malunions and nonunions: a systematic review

Although acute management of pelvic fractures and their long-term functional outcome have been widely documented, important information regarding malunion and nonunion of these fractures is sparse. Despite their relative rarity, malunions and nonunions cause disabling symptoms and have major socioeconomic implications. We analyzed the factors predisposing a pelvic injury to develop malunion/nonunion, the clinical presentation of these complications, and the efficacy of the reported operative protocols in 437 malunions/nonunions of 25 clinical studies. Treatment of these demanding complications appeared effective in the majority of the cases: overall union rates averaged 86.1%, pain relief as much as 93%, patient satisfaction 79%, and return to a preinjury level of activities 50%. Nevertheless, the patient should be informed about the incidence of perioperative complications, including neurologic injury (5.3%), symptomatic vein thrombosis (5.0%), pulmonary embolism (1.9%), and deep wound infection (1.6%). For a successful outcome, a thorough preoperative plan and methodical operative intervention are essential. In establishing effective evidence-based future clinical practice, the introduction of multicenter networks of pelvic trauma management appears a necessity.

Effectiveness of electromyographic biofeedback in the treatment of musculoskeletal pain

Electromyographic biofeedback is a therapeutic modality used along with other interventions in the treatment of pain. This article presents a brief review of the effectiveness of electromyographic biofeedback in treating musculoskeletal pain. Electromyographic biofeedback may provide pain relief for chronic musculoskeletal pain due to cumulative trauma, and may be proposed as an additional intervention to exercise in patellofemoral pain syndrome and acute sciatic pain. Electromyographic biofeedback is comparable to cognitive behavioral treatment and relaxation techniques. When added to an exercise program in patients with patellofemoral pain or acute sciatic pain, no further pain reduction is achieved. Electromyographic biofeedback promotes active participation and thus may motivate patients to adopt an active role in establishing and reaching goals in rehabilitation. Further research is required to investigate its effect on musculoskeletal pain.

Low-intensity electrical stimulation in wound healing: review of the efficacy of externally applied currents resembling the current of injury

OBJECTIVE

Low-intensity currents (LIC) have gained popularity during the last years, and nowadays the majority of electrotherapy units may produce LIC. On wounding, the body produces a current, the current of injury, which promotes healing. Still, this current may gradually decrease resulting occasionally to delayed or limited wound healing. Thus, by applying the same LIC externally, healing may be accelerated by sustaining the LIC throughout the healing phases. The first review of research studies on the effect of LIC on wound healing is attempted, which can be considered useful for the practicing clinician, to provide an overview of current evidence on the effectiveness of LIC and provide protocols of treatment.

METHODS

Comprehensive review of randomized-controlled trials investigating the effect of LIC on wound healing.

RESULTS

The review revealed that LIC promote wound healing and appear to be effective in the range of 200-800 muA. The direct current may be continuous or pulsed and polarity may or may not be reversed.

CONCLUSION

Research available indicates that LIC accelerate wound healing. Further research is required to clarify the healing effects of LIC on wounds.

Prevalence and current concepts of management of farmyard injuries

Farmyard injuries in young adults and the elderly usually result from machinery accidents, whereas children tend to be injured by runovers and motor vehicle collisions. A variety of farmyard injuries secondary to environmental and human factors may cause permanent disability or even death. Common injuries include lacerations, hand injuries, amputations, farm animal bites, fractures and dislocations. Special considerations should be taken into account when treating these injuries, focusing on their noteworthy bacterial load in order to minimise the risk of chronic morbidity.

Necrotising fasciitis of upper and lower limb: a systematic review

Necrotising fasciitis is a rapidly progressive, life threatening soft tissue infection. In a significant proportion of patients, the extremities are involved as a result of trauma, needle puncture or extravasation of drugs, often leading to limb loss and devastating disability. In this systematic review of necrotising fasciitis of the upper and lower extremities, we report on the clinical characteristics, the predisposing factors, the associated diseases, the pathogenic bacteria, the surgical treatment and the final outcome in terms of limb loss and mortality. Data for a total of 451 patients were analysed for each parameter of interest. A percentage of 22.3% of the reviewed patients underwent amputation or disarticulation of a limb following failure of multiple debridements to control infection and the mortality rate was estimated as high as 21.9%.
