Introduction: nerve lesions are potentially catastrophic injuries. They can cause motor loss, severe pain and neuroma formation. The superficial branch of the radial nerve is at risk during first dorsal compartment release, its injury can cause neuroma formation. Autologous nerve reconstruction is the gold standard for treatment of small nerve gaps. Cases presentation: we present two cases of adult women (F/47 y F/51) with a prior history of first dorsal compartment release in another institution. Both patients developed debilitating neuropathic pain, as well as allodynia in the surgical site. They were diagnosed with superficial radial nerve neuroma. Oral medication and physical therapy was attempted without success. Surgical exploration and autologous nerve reconstruction was performed. Both patients had excellent relief of pain from visual analogue scale (VAS 9-10 to VAS 1-2). Postoperatively, both patients recovered partial sensitivity to pain in the zones distal to the repair. Conclusions: neuromas are feared complications that occur with unrecognized nerve lesions during surgery, they are difficult to treat and require multidisciplinary management. These two cases demonstrate that autologous nerve reconstruction is an excellent option for recovering function in small gaps of nerve tissue. [ABSTRACT FROM AUTHOR]

Introduction: Tumors in the hand are rare, and malignant tumors in the hand are peculiar; However, primary pseudotumoral lesions of the hand, such as ganglion, are very frequent. Most of the tumors found in the bone and soft tissue can be presented in the same way in the hand but their frequency and distribution is different. Despite the low incidence of benign and malignant tumors in the hand, these can be locally invasive or compromise the hand function. The main objective of this study is to determine the epidemiology, types, location and management of tumors and pseudotumors of the hand in adults in the Mexican population. Material and methods: We designed a retrospective study by review of clinical records of patients in our institution with diagnosis of tumors or pseudotumors in hand from January 2007 to December 2016 evaluating variables such as age, gender, laterality, Diagnosis, histological lineage, localization and treatment. Results: Our study comprises 215 patients with an average age of 44.23 years, predominantly women. Pseudotumors are the most frequently encountered (synovial cyst), followed by benign soft tissue tumors, benign bone tumors, and, finally, malignant tumors. Discussion: After all we suggests a possible new classification for the hand that is simple, reproducible and give guidance for treatment. The need for a classification system is imminent to standardize diagnostics, guide future research, focus treatments and preserve hand function. [ABSTRACT FROM AUTHOR]

Background: Carpal tunnel syndrome (CTS) is the upper extremity neuropathy more frequent. Treatments led to the entrapment of the median nerve in the carpal tunnel are more complicated and the results less promising and unsatisfactory in diabetic patients. The objective of this study is to compare the results of strength and hand function in healthy patients against patients with diabetes mellitus type 2 (DM2) with a diagnosis of CTS before and after the open and endoscopic release of the carpal tunnel. Material and methods: This is an observational, retrospective and descriptive study for a period of five years where we evaluated the results in healthy patients and with DM2, with diagnosis of CTS who underwent surgical treatment by open or endoscopic approach; we applied the DASH questionnaire, force grip and clamp fine measurements, presence of infection, pain and complications. Results: The results of 86 patients evaluated, showed a statistical association in the decrease in scores on the functional scale DASH with both approaches, association between remission of hypoesthesias in healthy patients with either of the two approaches as opposed to diabetic patients and association between developing DM2 and complications in the short term. Conclusion: Both approaches improve symptoms and function of the hand in healthy and diabetic patients, but the fi rst group will present cases of complete remission in contrast to the group of diabetic patients.

Introduction: the glomus tumor is a benign neoplasm originated in the smooth muscle cells of the vascular glomus. Approximately 80% of lesions are located on the upper extremity and, of these, the majority are in the subungual area. The diagnosis must include imaging tests, among which ultrasound stands out, being a good alternative due to its low cost and accessibility., Objective: we present a case of late diagnosis of surgically managed glomus tumor, as well as a review of the existing literature for diagnosis, treatment, and prognosis of this uncommon pathology., Clinical Case: the case of a 52-year-old female patient who reported chronic, burning pain, radiating to the distal phalanx of the thumb with no history of trauma, of 2 years of evolution and which limited her daily life activities, is presented. The exploration with interphalangeal Doppler ultrasound is complemented, being an excellent alternative due to its easy accessibility. A glomus tumor was diagnosed in the interphalangeal thumb. An "H" approach was performed on the interphalangeal fold with subungual dissection with resection of the tumor piece and follow-up by an outpatient clinic where a surgical wound with adequate healing was found. Physical examination with capacity for the mobilization of the distal interphalangeal joint (IFJ) and visual analogue scale (VAS) 1 point. The updated pathological evaluation of the existence of a glomus tumor., Conclusions: ultrasound is an excellent aid in the diagnosis, as well as in the surgical planning for the treatment of the glomus tumor; for being accessible, low cost and highly effective. The anatomopathological study is the gold standard.

Objectives: The term "mixed pain" has been established when a mixture of different pain components (e.g. nociceptive, neuropathic, and nociplastic) are present. It has gained more and more acceptance amongst pain experts worldwide, but many questions around the concept of mixed pain are still unsolved. The sensation of pain is very personal. Cultural, social, personal experiences, idiomatic, and taxonomic differences should be taken into account during pain assessment. Therefore, a Latin American consensus committee was formed to further elaborate the essentials of mixed pain, focusing on the specific characteristics of the Latin American population., Methods: The current approach was based on a systematic literature search and review carried out in Medline. Eight topics about the definition, diagnosis, and treatment of mixed pain were discussed and voted for by a Latin American consensus committee and recommendations were expressed., Results: At the end of the meeting a total of 14 voting sheets were collected. The full consensus was obtained for 21 of 25 recommendations (15 strong agreement and 6 unanimous agreement) formulated for the above described 8 topics (7 of the 8 topics had for all questions at least a strong agreement - 1 topic had no agreement for all 4 questions)., Conclusion: In a subject as complex as mixed pain, a consensus has been reached among Latin American specialists on points related to the definition and essence of this pain, its diagnosis and treatment. Recommendations for diagnosis and treatment of mixed pain in Latin America were raised.

Introduction: Functional results of four surgical techniques to resolve the IIIB-IV Litchman's stage of the Kienböck disease were analyzed. We observed the evolution from 2000 to 2015., Material and Methods: Transversal retrospective study of 33 patients treated with different surgical techniques and evaluated with Quick-DASH scale, dynamometer and EVA., Results: Less functional limitation was found in the patients who underwent the intercarpal fusion with or without neurotomy of the posterior interosseous., Discussion: It was shown that the fact of making a less aggressive surgery is enough to evolve into an increase in symptoms and a decrease in function and strength; therefore, the intercarpal fusion performed at the right time of the natural history of the disease can achieve better results than other methods used previously and endorsed by international associations., Conclusions: The surgical technique of choice in our series to prevent disease progression was the intercarpal fusion and neurotomy of the posterior interosseous nerve.

Lyme disease is an emerging pathology in Mexico, producer of painful muscle skeletal either neurotic pain difficult to control. We present the case of a teenager girl who has complex regional pain type II of pelvic limb secondary to it, where it established a multidisciplinary management that finally was controlled with the placement of a spinal cord stimulator. We consider this as an unusual situation in an adolescent, as well as its evolution by 60 months where the literature only was reported in a few cases.
