This may improve for up to years from injury. Therefore the nerve can recover down the same track. Patients should avoid pressing heavily on the scar for 3 months following the operation as this will be quite painful. Nerves typically need protection for up to 6 weeks from injury. Use of the anterior branch of the medial antebrachial cutaneous nerve as a graft for the repair of defects of the digital nerve. However, the morbidity caused by sacrificing a functioning nerve resulted in searching for suitable non-autologous graft materials. Surgical repair of ulnar nerve lesions caused by gunshot and shrapnel:
Compression of the radial digital nerve of the thumb
Transection of radial digital nerve of the thumb during trigger release.
Broken nerve fibers or more severe injuries: Of the extrinsic hand muscles, the median nerve supplies flexor digitorum superficialis, flexor pollicis longus, and the radial half of flexor digitorum profundus. The nerve injury often follows a direct blow or stretch. Dry skin anhydrosis in the sensory distribution of a potentially cut nerve suggests a complete or partial laceration. One of these, recently published by Rinker et al. A series of causative factors is often involved to produce this rare, but serious complication Table 2. The nerves can be thought of as insulated electrical cables which allow electric impulses the signals from the brain to travel very fast to where they are needed.
A trend towards better outcome for sharp injuries was observed. Digital nerve injury can result from simple cuts or from severe hand trauma. For every centimeter of gap length, the estimated average increase in 2PD is 1. For managing the chronic nerve injury, one must first assess the primary complaint. Frozen muscle autografts appear to be applicable only for shorter distances. Peripheral Nerve Repair:
Operative Nerve Repair and Reconstruction. Therefore, we included articles with minimal six out of seven variables. Outcome of digital nerve injuries in adults. The management of digital nerve injuries. We are unable to redeem your access code. The aim of this review was to provide an update of the current surgical interventions for digital nerve repair.
