The postoperative course of median nerve decompression in the carpal tunnel syndrome may sometimes be complicated by postoperative pain, paresthesias, and other unpleasant symptoms, or be characterized by a slow recovery of nerve function due to prolonged preoperative injury causing extensive nerve damage. The aim of this study is to explore any possible effects of alpha lipoic acid (ALA) in the postoperative period after surgical decompression of the median nerve at the wrist. Patients were enrolled with proven carpal tunnel syndrome and randomly assigned into one of two groups: Group A: surgical decompression of the median nerve followed by ALA for 40 days. Group P: surgical decompression followed by placebo. The primary endpoint of the study was nerve conduction velocity at 3 months post surgery, Other endpoints were static 2 point discrimination, the Boston score for hand function, pillar pain and use of pain killers beyond the second postoperative day. ALA did not show to significantly improve nerve conduction velocity or Boston score. However, a statistically significant reduction in the postoperative incidence of pillar pain was noted in Group A. In addition, static 2 point discrimination showed to be significantly improved by ALA. Administration of ALA following decompression of the median nerve for carpal tunnel release is effective on nerve recovery, although this is not detectable through nerve conduction studies but in terms of accelerated and improved static two-point discrimination. The use of ALA as a supplementation for nerve recovery after surgical decompression may be extended to all types of compression syndromes or conditions where a nerve is freed from a mechanical insult. Furthermore, ALA limits post-decompression pain, including late pericicatricial pain at the base of the palm, the so called pillar pain, which seems to be associated with a reversible damage to the superfical sensitive small nerve fibers. In conclusion postoperative administration of ALA for 40 days post-median nerve decompression was positively associated with nerve recovery, induced a lower incidence of postoperative pillar pain and was associated with a more rapid improvement of static two-point discrimination. This treatment is well tolerated and associated with high levels of satisfaction and compliance, supporting its value as a standard postoperative supplementation after carpal tunnel decompression

Utilization of nerve conduction studies in the investigation and management of carpal tunnel syndrome varies according to their perceived usefulness and availability. The use of steroid injections and splinting also varies according to service availability and their perceived effectiveness. We present a three year follow up of 230 patients managed in an environment where nerve conduction testing was not readily available. The majority received splinting and a steroid injection in an effort to manage their symptoms conservatively in the first instance. Our results show that a clear majority of patients who were treated with initial splinting and steroid injections saw a recurrence of their symptoms (71.9% and 79.7% respectively) requiring eventual surgical decompression. These results would seem to suggest that conservative management of carpal tunnel does not produce the desired curative results and that there may be an argument for proceeding directly to surgery. We also showed that 55% of patients referred for Nerve Conduction Studies seem to progress to surgical decompression. This would seem to suggest that Nerve Conduction Studies could form a robust part of the standard investigation of carpal tunnel in order to identify those who would benefit from surgery

The Cochrane Collaboration has produced five new reviews relevant to bone and joint surgery since the publication of the last Cochrane Corner These reviews are relevant to a wide range of musculoskeletal specialists, and include reviews in Morton’s neuroma, scoliosis, vertebral fractures, carpal tunnel syndrome, and lower limb arthroplasty.

Compartment syndrome of the foot requires urgent surgical treatment. Currently, there is still no agreement on the number and location of the myofascial compartments of the foot. The aim of this cadaver study was to provide an anatomical basis for surgical decompression in the event of compartment syndrome. We found that there were three tough vertical fascial septae that extended from the hindfoot to the midfoot on the plantar aspect of the foot. These septae separated the posterior half of the foot into three compartments. The medial compartment containing the abductor hallucis was surrounded medially by skin and subcutaneous fat and laterally by the medial septum. The intermediate compartment, containing the flexor digitorum brevis and the quadratus plantae more deeply, was surrounded by the medial septum medially, the intermediate septum laterally and the main plantar aponeurosis on its plantar aspect. The lateral compartment containing the abductor digiti minimi was surrounded medially by the intermediate septum, laterally by the lateral septum and on its plantar aspect by the lateral band of the main plantar aponeurosis. No distinct myofascial compartments exist in the forefoot. Based on our findings, in theory, fasciotomy of the hindfoot compartments through a modified medial incision would be sufficient to decompress the foot

Background. To investigate the new theory of hydroneurolysis and hydrodissection in the treatment of carpal tunnel syndrome (CTS). Independently of the fluid hydrodissolution works due to mechanical forces and it may have some positive effects in patients with ischemic damage caused by scar tissue pressure at the nerve's surface. Methods. A prospective blind clinical study of 31 patients suffering from carpal tunnel syndrome, established by nerve conduction studies and clinical tests. 14 patients (out of 29), who refused to undergo an open operation as a treatment to their disease at this point of time, were treated with a simple ultrasound-guided injection at the proximal carpal tunnel. In order to exclude the biochemical influence of the fluid in the treating disease we choosed to infiltrate 3 cc. of normal saline 0,9%. In the follow-up period our group was asked to answer to a new Q-DASH score and visual analogue scale (VAS) 100/100 in 2, 4 and 8 weeks. Results. At the end of the second month we found only 2 out of 14 patients of the infiltration's group with clinical improvement. As far as the control group (17 patients), there was just one patient with recovery of the symptoms at the end of the second month who avoided operation. The rest 16 patients experienced insistence or worsening of CTS while they were waiting to be operated (mean time till operation in our department's waiting list: 2 months) and underwent a surgical decompression of the median nerve. Comparing the two groups in Q-DASH score, VAS 100/100 and ultrasound cross sectional area measurements we found no statistical difference between the two groups at the endpoint of our follow-up period. Conclusion. As far as nerve entrapment syndromes we proved that normal saline hydrodissolution appears to be non effective as a conservative treatment. The mechanical way of action seems to have only very short term effects. Level of Evidence. II

Scar tissue formation between nerve and surrounding muscle is one of the most undesired occurrence in nerve surgery In order to prevent scar tissue apposition after surgery, a lot of biocompatible products have been developed and tested first of all on animal models and then in surgical practice. we tested the efficacy of a CMC-PEO gel in reduction of perineural scar tissue formation in a mice model and in a small group of patients. We performed surgical procedures on 26 male mices The animals were randomized into three groups. In each group the muscular bed of sciatic nerve was burned with diathermocoagulator. In treated group we applied the tested gel in order to reduce the post surgical scar. After 3 weeks the strenght of the scar was studied using a specific tool. Also histologic analysis was performed. We also reported the results of CMC-PEO gel on 8 patients who underwent surgical decompression of peripheral nerves affected by recurrent compressive syndrome. The biomechanical analysis showed that gel application strongly reduces scar tissue. The difference between not treated and treated group was statistically significative. The histological analysis confirmed this data showing a cleavage plan between scar tissue and sciatic nerve. In patients we monitored VAS pre and post operative and we described reduction from 8 to 1 in 6 patients and from 6 to 1 in two patients. In conclusion, our study proves the efficacy in animal models of Dynavisc in scar tissue formation prevention and discloses the absolute security and biocompatibility of this products. Moreover also the small sample of patients showed the safety of this product on human, and proved its efficacy on recurrent nerve compression syndrome associated with neurolysis

Failure of conservative treatment for tennis elbow is an indication for surgical decompression. The Topaz® technique utilises radiofrequency to decompress(detension) the tendon and in addition, it is thought to stimulate angiogenesis thereby facilitating healing. Initially we reviewed the three month follow up of 25 tennis elbow decompressions performed using the Topaz® technique. The case notes were reviewed and findings recorded on a structured proforma. After a minimum of 1 year we re-reviewed the case notes to identify recurrences or patients requiring revision surgery. The majority of patients were aged between 35–50 years. 87% of patients had symptoms for more than 12 months and symptoms experienced were mainly pain (100%). All patients had a full trial of physiotherapy and had minimum of two steroid injections. At three month follow up symptoms were completely relieved or improved in 88%. All patients were given an open appointment to review if symptoms recurred. On review of the notes after a minimum of one year, 84% had no further clinic attendances. Four elbows re-attended with symptom recurrence, two underwent traditional open release and two declined revision surgery. In the two patients who declined further surgery, symptoms had resolved at one year. The results of the Topaz® technique are comparable to that of the results of the traditional release from the literature both in terms of success and problems. It would be important to compare it to the traditional release to gauge its benefits against the standard practice

Background and Aims. Transforaminal epidurals (TFEs) have been widely used as a treatment for lumbar radicular pain since its introduction by Krempen and Smith in 1974. 1. Originally used as a diagnostic tool, it is now becoming increasingly recognised as a definitive treatment. 2. This study investigates the use of TFEs by a single surgeon over 4 years. We hoped that the study would add to our understanding and the discussion of the actual benefit of therapeutic steroid and local anaesthetic injections by this route. 3. . Methods and Results. A total of 181 patients were identified. At injection 10mls 0.25% Marcaine and 40mg Depomedrone was injected under fluoroscopic guidance. Clinic notes and MRI reports for all patients were reviewed. Of the 176 patients included in the study, 127 showed a symptomatic improvement. Of these patients, 59 proceeded to surgical decompression. For 50 patients, TFE was the definitive treatment. 13 patients were offered but declined surgery. 5 patients were too frail to proceed to surgery. 49 patients showed no symptomatic improvement. Of this group, 34 were deemed unsuitable for surgical intervention. 15 patients did proceed to surgery. Conclusions and Discussion. These results are comparable to other similar case series. Vad et al. 3. demonstrated that 78% of patients studied were satisfied with the outcome of TFE. Riew et al. 2. showed that 53% of their study group avoided surgery due to positive long term effect of TFE. The operative notes of the 15 patients who proceeded to surgery despite a negative TFE outcome are being reviewed and will be presented. Conflicts of Interest. None. Source of Funding. None

Spinal nerve roots often sustain compression injuries. We used a Wistar rat model of the cauda equina syndrome to investigate such injuries. Rapid transient compression of the cauda equina was produced using a balloon catheter. The results were assessed by daily neurological examination and somatosensory evoked potential (SEP) recording before surgery and ten weeks after decompression. Compression of the spinal nerves induced changes in the SEP which persisted for up to ten weeks after decompression, but it had no effect on the final neurological outcome. Our study shows the importance of early surgical decompression for cauda equina syndrome

Study Purpose. To examine the presence of radicular pain and its relationship to the degree of lumbar nerve root compression in patients with a degenerative lumbar spine condition about to undergo surgery for either lumbar disc prolapse or lumbar canal stenosis. Background. The pathophysiology underlying radicular pain is not completely understood but it is thought that nerve root compression is a key factor and from a surgical perspective, decompressing the nerve root is considered to be the key therapeutic step. However, despite often severe root compression in patients with lumbar stenosis, radicular pain is not a typical feature. Methods. Thirty-nine pre-surgical patients with either lumbar disc prolapse or lumbar canal stenosis were studied using the Standardised Evaluation of Pain (StEP), a clinical assessment tool known to predict with a high degree of sensitivity and specificity the presence or absence of lumbar radicular pain. A nerve root compression score was given from lumbar MRI for each patient by a neuroradiologist blinded to the patients history. Results. The StEP assessment tool was able to distinguish the presence or absence of radicular pain with high sensitivity and specificity. This correlated well with the pre-operative diagnosis of disc prolapse or canal stenosis. The relationship between radicular pain and nerve root compression was less clear and will be discussed. Conclusion. This study confirms StEP as a useful bedside tool for identifying the presence of radicular pain in patients with a degenerative lumbar spine condition. Nerve root compression per se does not necessarily produce radicular pain. Conflicts of Interest. None. Source of Funding. None. This study has not been published or presented at a previous meeting
