Forensic Medicine and Anatomy Research (FMAR) , 2014, DOI: 10.4236/fmar.2014.21003
Abstract: Anomalous muscles in carpal tunnel (CT) may cause carpal tunnel syndrome (CTS), and may be also associated with neurovascular abnormalities, altering the diagnosis and surgical interventions for CTS. The authors report a case of bilateral Gantzer’s muscles (GMs) inserted into the tendons of flexor digitorum profundus within the CTs in an old male cadaver. The left GM was associated with enlarged lumbrical muscles in the CT and bifid median nerve (MN) communicating with ulnar nerve in the hand. The right GM was associated with perforation of MN branches in the hand by superficial palmar arch. This unreported coexistence of anomalous GMs and the associated neurovascular variations may have clinical relevance to etiology, diagnosis and treatment of CTS.

Abstract: a common ulnar nerve neuropraxia is lesion that may result in muscle strength decrease and/or paresthesia; it usually takes place at medial epicondyle level and the ulnar tunnel (guyon's canal). studies on manual therapy techniques for ulnar nerve compression in guyon's canal are scarce. this paper reports the use of a technique of pisiform bone mobilization for relieving ulnar nerve compression in guyon's canal, in a man who had suffered a luxation of the right wrist at the age of 8 and, at 25, complained of adduction deficit of the fifth finger that interfered in his daily life activities. he was submitted to one session of pisiform mobilization; after the session, the positive test sign was eliminated, thus restoring the fifth finger function. though lacking further grounding, it may be said that the technique used, of mobilizing the pisiform bone joint, is effective to restore normal function after ulnar nerve compression at the guyon's canal.

Abstract: Aims. Peroneal neuropathy, meralgia paresthetica and tarsal tunnel syndrome are the most common entrapment neuropathies of the lower extremities. Although, the effect of Body Mass Index on the entrapment neuropathies of the upper extremities, especially carpal tunnel syndrome, has been studied extensively, its effect on the entrapment neuropathies of the lower extremities, except meralgia paresthetica which is well known to be associated with obesity, is not well understood. In this study, we aimed to investigate the relations between Body Mass Index and the common entrapment neurophaties of the lower extremities. Methods. This retrospective study focused on 204 patients that were referred to our electrophysiology laboratory with a pre-diagnosis of peroneal neuropathy, meralgia paresthetica, and tarsal tunnel syndrome. Each group is separated into two subgroups consisting of patients with and without entrapment neuropathy. Age, sex, and Body Mass Index values are compared amongst the groups. In addition, all of the patients with a pre-diagnosis of entrapment neuropathy are further divided into two subgroups based on their Body Mass Index as ‘obese’ and ‘non-obese’ patients, and type and frequency of entrapment neuropathies are investigated. Results. The mean age of the patients pre-diagnosed with entrapment neuropathy was 42.61± 13.75. There were 97 men and 107 women. Of the 100 patients that were verified to have entrapment neuropathy, 39 were diagnosed with peroneal neuropathy, 39 with meralgia paresthetica and remaining 22 with tarsal tunnel syndrome. 93.8% of the ‘obese’ patients who admitted with the pre-diagnosis of meralgia paresthetica were confirmed to have this diagnosis. Body Mass Index values of the patients with verified meralgia paresthetica were significantly higher than those of the patients who were found not to have meralgia paresthetica. There were no significant differences regarding Body Mass Index values between the patients with and without peroneal neuropathy or tarsal tunnel syndrome. Conclusion. It is suggested that meralgia paresthetica is related to high Body Mass Index and obesity. Very limited number of the past studies mentioned associations between high Body Mass Index and tarsal tunnel syndrome, and weight loss and peroneal neuropathy. In this investigation, no significant association was found between obesity or emaciation and peroneal neuropathy or tarsal tunnel syndrome. In addition, the rate of meralgia paresthetica was higher in patients with advanced age, but there was no significant relationship between advancing

Abstract: peripheral nerves are commonly subject to traumatic injuries, leading to functional loss. low-power laser therapy has been used in order to minimize harmful effects of inflammation and to accelerate healing of injured tissues. the purpose of this study was to assess the effect of 830 nm-laser irradiation on rat sciatic nerves submitted to crush. twenty male wistar rats had their sciatic nerve crushed and were divided into 4 groups (n=5): sham7 and sham14, placebo-treated for 7 and 14 days; l7 and l14, laser-treated (at 4 j/cm2) for 7 and 14 days. sham group animals were submitted to the same procedures, but with the laser turned off. assessed parameters were inflammatory infiltrates, fibroblasts, myelin sheath destruction, and axonal degeneration. the statistical analysis showed significant differences in three parameters: l14 animals showed more fibroblasts (p=0.0001), lesser myelin sheath degeneration (p=0.007), and lesser inflammatory infiltrates (p=0.001). low-power laser therapy hence contributed to reduce the inflammatory process due to rat sciatic nerve injury.

Abstract: Cubital tunnel syndrome is one of the most frequently occurring compression neuropathy in the upper limb next to carpal tunnel syndrome. Recent minimal invasive technique has prompted us to gain clinical experience with simple in situ decompression with minimal skin incision for idiopathic cubital tunnel syndrome. Sixty six consecutive patients with cubital tunnel syndrome were treated using minimal skin incision technique. The mean age of the patients was 49.7 (range: 15-77) years and average follow up period was 23.9 months (range: 12-60 months). The severity of ulnar neuropathy was classified according to the McGowan classification: there were 17 in grade I , 47 in grade II and 2 in grade III. A preoperative nerve conduction study was done by inching method, which revealed motor conduction delay around the medial epicondyle. All operations were carried out in a day surgery unit under local anesthetics. The postoperative outcome was evaluated by Messina classification. The mean duration of the operation was 12 minutes. The technique was highly satisfactorily esthetic for all. Over 80% of the patients were completely satisfied with the procedure taking into consideration their symptoms. Postoperative outcome measures and patient satisfactions (pain, return to normal activities and work, scar and pillar tenderness) were comparable with published series of anterior transposition. The overall satisfactory results were recorded 81% in the patients of McGowan stage I and II. There were 2 cases of hematoma as a postoperative complication. This procedure is comparably effective alternative which involves less surgical trauma, morbidity and rehabilitation time with good surgical outcomes especially in mild and moderate degrees. Minimal skin incision is a simple, safe and effective method to treat patients with idiopathic cubital tunnel syndrome.

Abstract: emergence of intraneural hematoma with involvement of peripheral nerves can occur after trauma or coagulation disorders. the decision for expectant management or decompressive surgical techniques is still controversial. forty male wistar rats were divided into 4 groups. in group a, an intraneural injection of autologous blood was provided at the right sciatic nerve. in group b, after the hematoma creation, a longitudinal epineurotomy was performed. in the group c (sham-operated), the sciatic nerve was exposed without hematoma. in group d. immediately after the hematoma creation, an interfascicular neurolysis was performed. nerve function recovery was assessed using the bain-mackinnon-hunter sciatic function index (sfi). at the end of the study, the animals were sacrificed and a specimen of the sciatic nerve at compression midpoint was removed for morphometric analysis. group a displayed an initial sfi of -28.43, with full functional recovery on the fifth day. immediate drainage of the hematoma by longitudinal epineurotomy (group b) promoted recovery of normal sciatic function on the first day (sfi -14.42). addressing the hematoma via interfascicular neurolysis resulted in an initial sfi of -23.69 and recovery of normal sciatic function on the third day. the morphometric variables indicated an improvement of ischemic parameters following both types of surgical intervention.

Abstract: the basis of thoracic outlet syndrome (tos) surgical treatment is the first rib resection and may be associated with scalenectomy or cervical rib resection. the latter is traditionally done through a supraclavicular or axillary access, which is the most technically challenging. it can also be achieved through parascapular access. although technically attractive and associated with less invasiveness and increased security, with excellent aesthetic results, the first thoracic rib resection via video-assisted transaxillary surgery or videothoracoscopic technique is seldom reported in the literature, and no reference was found on cervical rib resection through this technique. in this article, we introduced this innovation successfully performed for surgical cervical rib resection in two patients.
