Acute carpal tunnel syndrome secondary to prolonged pressure on the wrist during enolic coma

We report a case of acute carpal tunnel syndrome caused by prolonged compression. A 40-year-old man was admitted for an acute carpal tunnel syndrome secondary to direct compression of the wrist which was blocked in supination under his thorax for ten hours during a period of alcoholic coma. Total sensorial anesthesia of the median nerve territory was noted. The emergency procedure consisted in simple opening of the carpal tunnel without nerve exploration due to the risk of bacterial contamination resulting from skin lesions, devascularization and postoperative fibrosis. Initially, the skin on the volar aspect of the wrist had the aspect of a second degree burn. The patient recovered nerve function the next day and the skin wound healed within 15 days. The patient was seen at consultation at 13 months and exhibited complete recovery of wrist and hand motion with normal thumb opposition and no signs of sensorial or motor deficit. The retinaculum of the flexor system must be opened to guarantee full nervous recovery.     

Acute carpal tunnel syndrome secondary to pyogenic tenosynovitis

We report a case of acute carpal tunnel syndrome related to a spontaneous pyogenic tenosynovitis and a review of this clinical condition.     

Acute carpal tunnel syndrome from burns of the hand and wrist

Acute median nerve compression usually occurs from increased pressure within the carpal tunnel and forearm compartments. Although the hyperesthesia from burns may mimic symptoms of acute compression neuropathy, clinical diagnosis should be made from history, clinical signs and symptoms. Early recognition and decompression of the carpal tunnel either as part of the burn excision or along with escharotomy usually leads to full recovery.     

Acute carpal tunnel syndrome caused by pigmented villonodular synovitis of the wrist

An 89-year-old woman developed an acute carpal tunnel syndrome secondary to hemarthrosis associated with pigmented villonodular synovitis of the wrist. Pigmented villonodular synovitis is rare in a patient of this age and is an unusual cause of carpal tunnel syndrome.     

Acute carpal tunnel syndrome

Carpal tunnel syndrome is considered the most common of the chronic compressive neuropathies. Its cause is generally unknown. Acute carpal tunnel syndrome, which is much less common, is more often directly related to fractures and fracture-dislocations about the wrist, hemorrhagic conditions, and vascular disorders involving the wrist. Many rare and unusual causes have been described, including chronic conditions that may be associated with acute carpal tunnel syndrome, such as rheumatologic disorders and anomalous anatomy. In contrast to the more common chronic idiopathic form, the acute form of carpal tunnel syndrome requires urgent surgical intervention to avoid or diminish serious sequelae.     

Acute carpal tunnel syndrome secondary to iatrogenic hemorrhage. A case report

Carpal tunnel syndrome is a common compression neuropathy of the median nerve. Acute carpal tunnel syndrome (aCTS) is rare, associated with a variety of conditions. In this case report we present a patient who developed aCTS and volar forearm compartment syndrome after a radial artery line placement, while receiving intravenous heparin. The patient underwent immediate forearm fasciotomy and surgical release for restoration of nerve function, which resulted in improved hand function and mild residual median nerve neuropathy. There is controversy whether to discontinue or not anticoagulation in a patient with aCTS. In our patient, heparin therapy was restarted on the second postoperative day.     

Acute carpal tunnel syndrome in trauma

Carpal tunnel syndrome (CTS) is one of the commonest compression neuropathy. It carries significant employment and health care costs and causes much grief to patients. There are numerous causes for carpal tunnel syndrome; however, in this review, the authors concentrate on trauma as a primary etiology. CTS is essentially a compression of the median nerve within the carpal tunnel producing debilitating symptoms and signs. Early recognition of the clinical presentation of this syndrome is vital, since it is a surgical emergency and urgent release is indicated. The anatomy, etiology, pathogenesis, clinical features, investigations, and management with case presentation have been discussed in detail, referencing a diverse collection of textbooks and papers. A comprehensive literature review of 44 papers was performed, with compilation of current treatment guidelines and management. Picture illustrations of a case encountered by the authors are included for better understanding for clinicians and trainees. This article describes acute CTS in detail and provides information for correct and early diagnosis together with effective treatment. The risk factors and treatment options are discussed in detail with photographic illustrations, providing simple but comprehensive material for education of students and clinicians, therefore to improve outcome of patients with this potentially devastating condition.     

Intrasynovial lipoma causing trigger wrist and carpal tunnel syndrome

Triggering of the flexor tendon at the wrist is rare. We report a case of intrasynovial lipoma that caused a trigger wrist. As far as we know it is unique in that the intrasynovial lipoma simultaneously caused carpal tunnel syndrome. The massive tenosynovitis and adhesion of flexors tendons after the locking of the intrasynovial lipoma may have resulted from inflammation caused by attrition within the carpal tunnel.

Carpal tunnel syndrome secondary to wrist and finger flexor spasticity

Ten patients with spastic wrist flexion deformities secondary to traumatic brain injury were evaluated for carpal tunnel syndrome. The angle of wrist flexion deformity averaged 75 degrees (range, 58 to 115 degrees). Nerve conduction studies demonstrated prolonged median motor and/or sensory latencies in all patients. Preoperative wick catheter measurements of carpal tunnel pressures in eight patients averaged 11 mm Hg in the resting position, 21 mm Hg in maximal wrist flexion, and 15 mm Hg in maximal extension. Each patient had carpal tunnel release with simultaneous wrist and finger flexor tendon releases or lengthenings. At surgery nine of the median nerves were constricted at the proximal edge of the transverse carpal ligament. The presence of normal carpal tunnel pressures and impingement of the median nerve at the proximal edge of the transverse carpal ligament indicates that the chronically flexed posture of the wrist resulted in median nerve compression, and this condition may be aggravated by underlying pressure from the spastic finger flexors.     

The role of wrist anthropometric measurement in idiopathic carpal tunnel syndrome

Anthropometric wrist measurement ratios were examined for an association with idiopathic carpal tunnel syndrome (CTS). Wrist measurements were recorded in 67 patients with CTS and in a matched control group of 67 healthy volunteers. The Wrist Ratio (WR) (wrist anterior to posterior dimension/wrist medial-lateral dimension) and the Wrist Palm Ratio (wrist anterior to posterior dimension/palm length) were calculated for each case. We found that a WR of > or =0.70 and a Wrist Palm Ratio of >0.342 were significantly associated with idiopathic CTS.     

Acute carpal tunnel syndrome due to a hemangioma of the median nerve

Hemangioma of the median nerve presenting as acute carpal tunnel syndrome is unusual A-18- year old male presented with severe incapacitating pain of sudden onset of left forearm and hand after manual field work. There was swelling on volar aspect of forearm, with hyperalgesia in the median nerve distribution. The fingers and wrist were inmarked flexion and the patient did not allow wrist and finger extension. X-rays were within normal limits. An emergency volar carpal ligament release revealed, haematoma about 100 ml with numerous vessels encircling the median nerve. Histopathology of lesion turned out to be a cavernous hemangioma. Post operatively patient had full recovery.     

Acute carpal tunnel syndrome caused by pseudogout.

Acute carpal tunnel syndrome caused by pseudogout occurred in a Chinese patient. The radiological findings mimicked those of synovial chondromatosis. Such radiological findings were very unusual. Diagnosis of such conditions may be difficult, since the clinical features may be confused with those of gout and infection. Surgical release is the treatment of choice.     

Acute carpal tunnel syndrome: a case report

We describe the development of acute carpal tunnel syndrome in a 53-year-old female following intensive repetitive use of the left wrist for two consecutive days.     

Acute carpal tunnel syndrome resulting from haemorrhage into the carpal tunnel in a patient on Warfarin

A case of acute compression neuropathy of the median nerve associated with haemorrhage into the carpal tunnel is presented. The condition occurred spontaneously in a patient on Warfarin for previous deep venous thrombosis. The signs and symptoms were those of acute tenosynovitis originating in the common flexor synovial sheath at the wrist with associated paraesthesia in the distribution area of the median nerve in the hand. The patient was afebrile and blood tests were normal.
