Cross-Sectional Evaluation of the Economic Burden on Patients Seeking Surgical Treatment for Chronic Nerve Injuries.

INTRODUCTION: Little emphasis has been paid toward characterizing the socioeconomic burdens experienced by patients seeking treatment for chronic nerve injuries. The aim of this study was to characterize the direct and indirect costs faced by patients with chronic nerve injuries and their attendant health care utilization. MATERIALS AND METHODS: A cross-sectional survey was distributed to all patients (N = 767) from a single nerve surgeon's practice treated for chronic nerve injuries in the ambulatory setting between 2014 and 2020. Data collected included demographics, etiology, comorbidities, duration and severity of symptoms, history of prior medical and interventional treatments, work or school time lost due to injury or treatment, money spent on treatment, and health care utilization. RESULTS: Of the 767 patients, 209 (27.2%) completed the survey. Average age was 48.8 (SD = 19.1) years, 68.9% female and 31.1% male. Patients with chronic nerve injury reported significant direct costs, indirect costs, and health care utilization associated with their nerve injury symptoms. Direct costs consisted of out-of-pocket spending (68.4% had spent >$1000 per year), physician specialists visits (71.3% had seen at least 4 specialists), and prior interventional procedures intended to address symptoms. Indirect costs included lost time from work or school (24.6% had missed more than 12 months). Health care utilization, represented by annual emergency room visits and hospitalizations related to nerve symptoms, was increased relative to the general population. Detailed statistics are presented in the manuscript. CONCLUSIONS: Chronic nerve injuries may be associated with a notable socioeconomic burden to the patient, including missed work or school, frequent physician visits and procedures, hospital visits, and out-of-pocket costs. Interdisciplinary algorithms recognizing a role for surgical evaluation in patients with chronic neuropathic pain due to underlying nerve injuries would facilitate future research into whether timely surgical intervention may reduce this economic burden.

Translating Technique into Outcomes in Amputation Surgeries.

The department of surgery at Washington University is putting increased emphasis on outcomes for amputees. This multidisciplinary effort begins with choosing the correct surgery and incorporating the latest technical advances in amputation surgery.

Carotid artery dissection and stroke complicating treatment of postmandibular distraction ankylosis: a case report.

Mandibular distraction osteogenesis is an increasingly accepted treatment option for severe upper airway obstruction in grade 3 Robin sequence. Complications are rarely reported but can include fracture, pin dislodgement, tooth bud damage, and temporomandibular joint ankylosis. Operative correction of these complications can carry inherent risks of their own. We present a patient who incurred carotid artery dissection and stroke after release of postdistraction coronoid-zygomatic ankylosis for the treatment of mandibular micrognathia.

Greater occipital nerve excision for occipital neuralgia refractory to nerve decompression.

BACKGROUND: Patients who undergo occipital nerve decompression for treatment of migraine headaches due to occipital neuralgia have already exhausted medical options for treatment. When surgical decompression fails, it is unknown how best to help these patients. We examine our experience performing greater occipital nerve (GON) excision for pain relief in this select, refractory group of patients. METHODS: A retrospective chart review supplemented by a follow-up survey was performed on all patients under the care of the senior author who had undergone GON excision after failing occipital nerve decompression. Headache severity was measured by the migraine headache index (MHI) and disability by the migraine disability assessment. Success rate was considered the percentage of patients who experienced a 50% or greater reduction in MHI at final follow-up. RESULTS: Seventy-one of 108 patients responded to the follow-up survey and were included in the study. Average follow-up was 33 months. The success rate of surgery was 70.4%; 41% of patients showed a 90% or greater decrease in MHI. The MHI changed, on average, from 146 to 49, for an average reduction of 63% (P < 0.001). Migraine disability assessment scores decreased by an average of 49% (P < 0.001). Multivariate analysis revealed that a diagnosis of cervicogenic headache was associated with failure of surgery. The most common adverse effect was bothersome numbness or hypersensitivity in the denervated area, occurring in up to 31% of patients. CONCLUSIONS: Excision of the GON is a valid option for pain relief in patients with occipital headaches refractory to both medical treatment and surgical decompression. Potential risks include failure in patients with cervicogenic headache and hypersensitivity of the denervated area. To provide the best outcome to these patients who have failed all previous medical and surgical treatments, a multidisciplinary team approach remains critical.

A systematic review of peripheral nerve interventional treatments for chronic headaches.

OBJECTIVE: This study aimed to systematically compare the outcomes of different types of interventional procedures offered for the treatment of headaches and targeted toward peripheral nerves based on available published literature. BACKGROUND: Multiple procedural modalities targeted at peripheral nerves are being offered to patients for the treatment of chronic headaches. However, few resources exist to compare the effectiveness of these modalities. The objective of this study was to systematically review the literature to compare the published outcomes and effectiveness of peripheral nerve surgery, radiofrequency (RF) therapy, and peripheral nerve stimulators for chronic headaches, migraines, and occipital neuralgia. METHODS: A broad literature search of the MEDLINE and CENTRAL (Cochrane) databases was undertaken. Relevant studies were selected by 2 independent reviewers and these results were narrowed further by the application of predetermined inclusion and exclusion criteria. Studies were assessed for quality, and data were extracted regarding study characteristics (study type, level of evidence, type of intervention, and number of patients) and objective outcomes (success rate, length of follow-up, and complications). Pooled analysis was performed to compare success rates and complications between modality types. RESULTS: Of an initial 250 search results, 26 studies met the inclusion criteria. Of these, 14 articles studied nerve decompression, 9 studied peripheral nerve stimulation, and 3 studied RF intervention. When study populations and results were pooled, a total of 1253 patients had undergone nerve decompression with an 86% success rate, 184 patients were treated by nerve stimulation with a 68% success rate, and 131 patients were treated by RF with a 55% success rate. When compared to one another, these success rates were all statistically significantly different. Neither nerve decompression nor RF reported complications requiring a return to the operating room, whereas implantable nerve stimulators had a 31.5% rate of such complications. Minor complication rates were similar among all 3 procedures. CONCLUSIONS: Of the 3 most commonly encountered interventional procedures for chronic headaches, peripheral nerve surgery via decompression of involved peripheral nerves has been the best-studied modality in terms of total number of studies, level of evidence of published studies, and length of follow-up. Reported success rates for nerve decompression or excision tend to be higher than those for peripheral nerve stimulation or for RF, although poor study quantity and quality prohibit an accurate comparative analysis. Of the 3 procedures, peripheral nerve stimulator implantation was associated with the greatest number of complications. Although peripheral nerve surgery seems to be the interventional treatment modality that is currently best supported by the literature, better controlled and normalized high-quality studies will help to better define the specific roles for each type of intervention.

Nerve Injuries in Aesthetic Breast Surgery: Systematic Review and Treatment Options.

BACKGROUND: The risk of nerve injuries in aesthetic breast surgery has not been well explored. OBJECTIVES: The authors conducted a systematic review to provide evidence-based information on the incidence and treatment of nerve injuries resulting from aesthetic breast surgery. METHODS: A broad literature search of Medline, Embase, and the Cochrane Database of Systematic Reviews was undertaken to identify studies in which nerve injury occurred after breast augmentation or mastopexy. Specific inclusion and exclusion criteria were established before the search was performed. RESULTS: The initial 4806 citations were narrowed by topic, title, and abstract to 53 articles. After full-text review, 36 studies were included. The risk of any nerve injury after breast augmentation ranged from 13.57% to 15.44%. Specific nerve injury rates were calculated for the intercostal cutaneous nerves, branches to the nipple-areola complex, intercostobrachial nerve, long thoracic nerve, and brachial plexus. Also calculated were the total estimated risks of chronic pain, hyperesthesia, hypoesthesia, and numbness. The meta-analysis showed no associations between the rates of breast nerve injury or sensation change and implant size, incision type, or implant position in patients who underwent breast augmentation. The data were insufficient to determine rates of nerve injury in mastopexy. CONCLUSIONS: The possibility of nerve injury, sensation change, or chronic pain with breast augmentation is real, and estimating the incidences of these conditions is useful to both patients and surgeons. Optimizing patient outcomes requires timely treatment by a multidisciplinary team and may include peripheral nerve surgery. LEVEL OF EVIDENCE: 3.

Abdominoplasty-related nerve injuries: systematic review and treatment options.

BACKGROUND: Abdominoplasty is a common cosmetic procedure; nerve injury is an underexplored risk of the procedure. OBJECTIVE: The authors review existing literature to examine the incidence and treatment of nerve injuries after abdominoplasty procedures and provide a treatment algorithm based on their results. METHODS: A search of the literature on MEDLINE, EMBASE, and the Cochrane Database of Systematic Reviews was undertaken. After full-text review, 23 articles met our criteria. Any mentions of nerve injury, including references to a lack of nerve injury, were documented. All data were pooled for analysis. From our combined data, we calculated the risks of postabdominoplasty nerve injury by dividing the total number of nerve injuries by the total number of patients. RESULTS: Pooled data showed that 1.94% of patients sustained specific nerve injury, and 1.02% of patients sustained permanent injury after abdominoplasty. In addition, 7.67% experienced decreased sensation, 1.07% reported chronic pain, and 0.44% reported temporary weakness or paralysis. Nerves directly injured were the lateral femoral cutaneous (1.36% of patients) and iliohypogastric (0.10%) nerves. Nerves injured from surgical positioning were the brachial plexus (0.10%), musculocutaneous (0.10%), radial (0.05%), sciatic (0.19%), and common peroneal (0.05%) nerves. CONCLUSIONS: Although our results showed a low incidence of postabdominoplasty nerve injury, the lasting impact on affected patients' quality of life can be significant. Appropriate and timely treatment by a multidisciplinary team is critical to optimize patient outcomes. Better reporting of nerve injuries in future studies of abdominoplasty will provide more accurate information about the incidence and consequences of these injuries. LEVEL OF EVIDENCE: 4.

Surgical Technique for Targeted Muscle Reinnervation in Knee Disarticulation Amputation for Nonambulatory Patients.

Chronic neuropathic pain following major limb amputation has historically been difficult to treat. In patients undergoing lower extremity amputation, "preemptive" targeted muscle reinnervation (TMR) nerve transfers may be performed concurrently with the amputation to help mitigate the risk of chronic neuropathic postoperative pain. Despite clinical studies demonstrating efficacy of TMR in lower extremity amputations, few procedural descriptions have been written, and none have been written regarding performing TMR at the knee disarticulation (KD) level of amputation. Although uncommonly utilized, the KD amputation has clear functional benefits over other levels of amputation for nonambulatory patients. As nonambulatory patients are also subject to the occurrence of chronic neuropathic postamputation pain, it stands to reason that the addition of TMR to KD surgery could be an improvement to standard techniques. In this report, we provide a technical description for concurrent TMR with KD and describe the rationale for its use.

Successful Use of Delayed Reverse Sural Artery Flap in Single Vessel Legs with Severe Atherosclerotic Disease and Venous Insufficiency.

Distal lower extremity wounds are a challenging problem for reconstructive surgeons and can lead to major lower extremity amputations in patients with comorbid conditions. The reverse sural artery flap (RSAF) is a local flap supplied by perforators of the peroneal artery that can cover defects of the distal lower extremity, ankle, and foot. There has been concern over performing the RSAF in patients with venous insufficiency, peripheral artery disease, and diabetes, and in older patients due to the increased risk of flap necrosis. In patients who are not microsurgical candidates, the RSAF may be the final option for reconstruction before undergoing major lower extremity amputation. We describe our experience with two patients with significant comorbidities and single vessel runoff from the peroneal artery due to atherosclerotic disease who successfully underwent RSAF reconstruction for distal lower extremity wounds.

Postoperative headache following acoustic neuroma resection: occipital nerve injuries are associated with a treatable occipital neuralgia.

OBJECTIVE: To demonstrate that occipital nerve injury is associated with chronic postoperative headache in patients who have undergone acoustic neuroma excision and to determine whether occipital nerve excision is an effective treatment for these headaches. BACKGROUND: Few previous reports have discussed the role of occipital nerve injury in the pathogenesis of the postoperative headache noted to commonly occur following the retrosigmoid approach to acoustic neuroma resection. No studies have supported a direct etiologic link between the two. The authors report on a series of acoustic neuroma patients with postoperative headache presenting as occipital neuralgia who were found to have occipital nerve injuries and were treated for chronic headache by excision of the injured nerves. METHODS: Records were reviewed to identify patients who had undergone surgical excision of the greater and lesser occipital nerves for refractory chronic postoperative headache following acoustic neuroma resection. Primary outcomes examined were change in migraine headache index, change in number of pain medications used, continued use of narcotics, patient satisfaction, and change in quality of life. Follow-up was in clinic and via telephone interview. RESULTS: Seven patients underwent excision of the greater and lesser occipital nerves. All met diagnostic criteria for occipital neuralgia and failed conservative management. Six of 7 patients experienced pain reduction of greater than 80% on the migraine index. Average pain medication use decreased from 6 to 2 per patient; 3 of 5 patients achieved independence from narcotics. Six patients experienced 80% or greater improvement in quality of life at an average follow-up of 32 months. There was one treatment failure. Occipital nerve neuroma or nerve entrapment was identified during surgery in all cases where treatment was successful but not in the treatment failure. CONCLUSION: In contradistinction to previous reports, we have identified a subset of patients in whom the syndrome of postoperative headache appears directly related to the presence of occipital nerve injuries. In patients with postoperative headache meeting diagnostic criteria for occipital neuralgia, occipital nerve excision appears to provide relief of the headache syndrome and meaningful improvement in quality of life. Further studies are needed to confirm these results and to determine whether occipital nerve injury may present as headache types other than occipital neuralgia. These findings suggest that patients presenting with chronic postoperative headache should be screened for the presence of surgically treatable occipital nerve injuries.

Common nerve decompressions of the upper extremity: reliable exposure using shorter incisions.

UNLABELLED: Considering that several different specialties perform nerve decompressions in the upper extremity, universal technical standards do not exist. Many of these procedures are performed via incisions that are made unnecessarily long to achieve adequate exposure of the nerves and their known anatomical compression points. The purpose of this article is to introduce reproducible techniques that reliably allow the necessary anatomical exposure while minimizing the length of required skin incisions. METHODS: The senior author's surgical approach to the most common nerve compression syndromes of the upper extremity is presented in detail. Typical incision lengths and surgical exposure are demonstrated photographically. The safety of using this technique is examined by review of the medical records of all patients undergoing this procedure from 2003 to 2011, looking for technical complications such as unintentional damage to nerves or adjacent structures. RESULTS: Three hundred twenty consecutive cases were identified in which the described techniques were used to release known anatomical compression points of the upper extremity nerves, including 161 decompressions of the ulnar nerve at the elbow, 37 decompressions of the anterior interosseous nerve and 45 of the posterior interosseous nerve in the proximal forearm, and 77 decompressions of the radial sensory nerve in the distal forearm. Typical incision lengths we used for these procedures were 5 cm for the ulnar nerve, 4.5 cm for the anterior interosseous nerve, 4 cm for the posterior interosseous nerve, and 3 cm for the radial sensory nerve. Review of medical records revealed no incidences of unintentional injury to nerves or adjacent important structures. Functional and neurological recovery outcomes were not assessed, as those would be the subject of subsequent studies. CONCLUSIONS: Known anatomical compression points can be reliably accessed and decompressed for the treatment of all common upper extremity nerve compression syndromes using minimized skin incisions and the techniques presented in this article. With appropriate knowledge of anatomy, this can be performed without expensive equipment or any additional risk of injury to the patient, making classically described longer incisions unnecessarily morbid.

Minimally invasive peripheral nerve surgery: peroneal nerve neurolysis.

BACKGROUND: Both patients and surgeons recognize the value of procedures that minimize scarring and tissue dissection. No previous reports have described a minimally invasive technique for peroneal nerve neurolysis, or evaluated its safety. METHODS: The senior author's technique for a minimally invasive approach to neurolysis of the common, superficial, and deep peroneal nerves is presented. Safety of the technique was determined by review of records of all patients undergoing this procedure from 2003-2011, looking for major complications. RESULTS: Using the minimally invasive approach to peroneal nerve neurolysis, average skin incision size is 3.5 cm for the common peroneal nerve, 4 cm for the superficial peroneal nerve, and 2.5 cm for the deep peroneal nerve. In 400 patients undergoing 679 total procedures, there were no nerve injuries, postoperative neuromas, or adjacent structures harmed. CONCLUSIONS: Peroneal nerve neurolysis can be accomplished safely and effectively via a minimal skin incision, improving aesthetic results and decreasing possible scar-related complications.

Tibial nerve decompression: reliable exposure using shorter incisions.

BACKGROUND: Patients and surgeons recognize the value of procedures that minimize scarring and tissue dissection, but technical standards do not exist with regards to incision lengths needed for tibial nerve decompression. This article introduces reproducible techniques that reliably provide exposure for release of known anatomical compression points of the tibial nerve, while minimizing the length of required skin incisions. METHODS: The senior author's approach to decompression of the tibial nerve at the soleus arch and the tarsal tunnel is presented. Typical incision lengths and surgical exposure are demonstrated photographically. The safety of using this technique is examined by review of the medical records of all patients undergoing this procedure from 2003 to 2011, looking for technical complications such as unintentional damage to nerves or adjacent structures. RESULTS: 224 consecutive patients undergoing 252 total procedures underwent release of known anatomical compression points of the tibial nerve at either the tarsal tunnel, inner ankle, or the soleus arch. Typical incision lengths used for these procedures were 5 cm for the proximal calf and 4.5 cm for the tarsal tunnel. Review of medical records revealed no incidences of unintentional injury to nerves or adjacent important structures. Functional and neurological outcomes were not assessed. CONCLUSIONS: Tibial nerve decompression by release of known anatomical compression points can be accomplished safely and effectively via minimized skin incisions using the presented techniques. With appropriate knowledge of anatomy, this can be performed without additional risk of injury to the patient, making classically-described longer incisions unnecessarily morbid.

Pronator Quadratus: A Preferable Recipient for Targeted Muscle Reinnervation of Neuromas in the Hand.

Targeted muscle reinnervation (TMR) has emerged as a useful solution to the problem of painful neuromas and is increasingly being applied in many clinical circumstances. Relatively little has been written about TMR for painful neuromas of the hand, and what has been written describes use of the intrinsic muscles as recipients for the nerve transfer. Except in cases of amputation, intrinsic muscle sacrifice carries morbidity. Furthermore, TMR to intrinsic muscles will place the nerve coaptation in areas subject to pressure with loading of the palm. For these reasons, the pronator quadratus may be a preferable target muscle when performing TMR for painful neuromas of the hand. In this report, we describe the rationale for its use and demonstrate the surgical technique and outcomes with case examples.

The SIEA SHRIMP Flap: An Ultrathin Axial Pattern Free Flap Useable in Obese Patients.

The reconstruction of distal extremity wounds poses a unique surgical challenge. In free tissue transfer, a thin, pliable skin flap is the ideal. Obese patients have a paucity of thin skin donor sites. Herein we report the discovery of a free SHRIMP flap (Superthin Harvest of a Reliable Islanded Medial Pannus flap) based on the SIEA vessels, harvested from a thick abdominal pannus at the time of cosmetic abdominoplasty. A 61-year-old woman with a chronic wound of the right Achilles tendon was evaluated for reconstruction after failing conservative measures. At the time of consultation, the patient expressed interest in abdominoplasty. Therefore, a skin flap from the abdomen or rectus abdominis muscle flap in the context of an abdominoplasty was offered. Despite obesity affecting the pannus, the superficial inferior epigastric vessels were found to course superficially beneath the dermis at time of abdominoplasty. This allowed straightforward harvest of a superthin flap of skin and minimal subcutaneous fat, which contoured to the ankle with an aesthetically pleasing outcome. The patient was satisfied with the results of her abdominoplasty and coverage of her chronic wound. The SHRIMP flap provides a straightforward, axial pattern, superthin free skin flap based on the superficial inferior epigastric vessels, and represents a useful option in obese patients. The flap can be combined with abdominoplasty for an aesthetic donor site.

Failed Targeted Muscle Reinnervation: Findings at Revision Surgery and Concepts for Success.

Although it was initially described for improved myoelectric control, targeted muscle reinnervation (TMR) has quickly gained popularity as a technique for neuroma control. With this rapid increase in utilization has come broadening indications and variability in the described technique. As a result, it becomes difficult to interpret published outcomes. Furthermore, there is no literature discussing the management of failed cases which are undoubtedly occurring. Methods: This is a retrospective case series of two patients who underwent revision surgery for failed TMR. The authors also review the current literature on TMR and outline technical and conceptual pitfalls and pearls based on our local experience. Results: Excessive donor nerve redundancy, kinking, donor-recipient nerve size mismatch, superficial placement of the nerve coaptation, inappropriate target selection, and incomplete target muscle denervation were identified as technical pitfalls of TMR surgery. Techniques to avoid these pitfalls were described. Conclusions: Although TMR has been a major development in amputee care for both pain management and improved myoelectric control, it is important to acknowledge that it is not a foolproof surgery and does not provide a guaranteed result. Failed cases of TMR represent opportunities to learn about factors contributing to unfavorable outcomes and refine our techniques empirically.

Anterior branch of the obturator nerve: a novel motor autograft for complex peripheral nerve reconstruction.

BACKGROUND: Autografting is the optimal reconstruction for many nerve gaps, because the retained nerve architecture serves as a regenerative scaffold. Experimental evidence suggests that motor regeneration is favored with the use of a motor nerve graft as compared with sensory nerve autografts, but clinical descriptions are lacking in the literature. As a novel solution, we report our use of the anterior branch of the obturator nerve as a large segment motor nerve graft with minimal functional morbidity. CASE: A 17-year-old boy reported progressive weakness and atrophy of the right thigh due to a multifascicular femoral nerve tumor. Motor branch defects of 7 and 4 cm were reconstructed using autografts from the motor nerve to the gracilis (MNG). The patient noted gradual clinical improvement in quadriceps strength, and repeat electromyography at 8- and 13-month follow-ups demonstrated improving motor unit action potentials and quadriceps muscle recruitment. DISCUSSION: The MNG is readily available, with an average total donor length of 11.4 cm. The use of motor nerve grafts is supported by experimental models demonstrating superior nerve regeneration. The MNG is a compelling choice for clinical use because donor-site morbidity is minimized by redundancy of the thigh adductors and a favorable incision location. CONCLUSION: This is the first published description of successful use of the anterior branch of the obturator nerve as a robust donor motor nerve graft. Clinical use of this graft may maximize functional outcomes and minimizes donor-site morbidity compared with traditional sensory nerve grafts.

Abdominal wall reconstruction with implantable meshes.

Abdominal wall defects present a difficult problem for the reconstructive surgeon. Over the years, numerous implantable materials have becomes available to aid the surgeon in recreating the abdominal wall. This spectrum of implants includes permanent synthetic meshes, absorbable meshes, composite meshes and biomaterials. This review includes the pros and cons for the commercially available abdominal wall implants as well as a review of the literature regarding outcomes for each material. This review will provide the surgeon with current evidence-based information on implantable abdominal materials to be able to make a more informed decision about which implant to use.

Impact of Nerve Surgery on Opioid and Medication Use in Patients with Chronic Nerve Injuries.

INTRODUCTION: Limited information is available regarding the ability of nerve surgery to affect medication use patterns in patients with chronic pain or neuropathy due to nerve injury. METHODS: A retrospective survey was distributed to all operative patients (N = 767) from a single nerve surgeon's practice between 2014 and 2020. Data collected included demographics, specifics of the injury and symptoms, medication and opioid use before surgery, and medication/opioid use following surgery. RESULTS: Out of the 767 patients, 209 (27.2%) completed the survey. Average age was 48.8 (SD = 19.1) years; 68.9% female and 31.1% male. More than 50% of the patients took at least three medications. More than 50% of the patients after surgery did not need medication or had significant reduction; 54.1% of the patients took opioid medication daily, and 97.3% of patients reported that narcotic medications did not resolve their problem. Patients rated the effectiveness (Likert scale 0-10) of opioid medications in general at an average 3.25 ± 2.03. Of patients who took opioids regularly, 61.6% reported a negative effect of these medications on daily or professional activities. After surgery, more than 50% of the patients did not need opioids or had a significant reduction in opioid usage. CONCLUSIONS: Untreated nerve injuries lead to ongoing chronic pain, explaining why medications are mostly ineffective in eliminating symptoms. In this study, nerve surgery targeting the anatomical source of symptoms effectively reduced both opioid and nonopioid medication use.

Chronic Nerve Injuries and Delays in Surgical Treatment Negatively Impact Patient-reported Quality of Life.

Little emphasis has been paid to characterize quality of life (QoL) burdens experienced by patients seeking surgical treatment for nerve injuries and neuropathic pain. METHODS: A cross-sectional survey was distributed to all patients (N = 767) from a single nerve surgeon's practice between 2014 and 2019. Data collected included demographics, specifics of the injury and symptoms, time to referral, and effects of the injury, surgery, and timing of surgery on QoL. RESULTS: Of the 767 patients, 209 (27.2%) completed the survey. Average age was 48.8 years; 68.9% of patients were women and 31.1% men. At presentation, 68% had experienced symptoms for more than 1 year; 86.1% reported severity as being profound; 97.6% reported QoL was at least moderately negatively impacted by nerve injury; 70% felt they should have been referred earlier for surgical evaluation; 51.2% were not told that nerve surgery was an option for their problem; 83.1% felt that earlier referral would have improved their QoL. After surgery, symptoms were significantly mitigated in 55.5% of the patients, moderately mitigated in 21.5%. Patients reported QoL was significantly (59.8%) or at least moderately (76.6%) improved by nerve surgery. CONCLUSIONS: The majority of patients reported that nerve injuries imparted a moderate to severe impact on QoL, and that surgical treatment improved QoL. Most patients felt that earlier referral for surgical intervention would have led to better outcome and positively impacted QoL. Interdisciplinary treatment algorithms, including a role for surgical intervention, may be helpful in facilitating timely diagnosis, referral, and thus improved outcomes.
