  • subterminal key pinch dynamometry a new method to quantify strength deficit in Ulnar Nerve Paralysis
    Journal of Hand Surgery (European Volume), 2020
    Co-Authors: Jayme Augusto Bertelli
    Abstract:

    Precise pre- and postoperative assessments are fundamental to recording the quality of recovery after Ulnar Nerve repair. Because of its imprecision, manual muscle testing is being replaced by dyna...

  • Prior to Repair Functional Deficits in Above- And Below-Elbow Ulnar Nerve Injury
    Journal of Hand Surgery (European Volume), 2020
    Co-Authors: Jayme Augusto Bertelli
    Abstract:

    Purpose Clinical deficits might vary, depending on whether an Ulnar Nerve lesion is above or below the elbow. Lack of strength and clawing are common manifestations of Ulnar Nerve Paralysis. However, the magnitude of strength deficit relating to different pinch patterns and the rate and range of proximal interphalangeal extension deficits are poorly described. Methods I prospectively evaluated 14 patients with above-elbow and 16 with below-elbow unrepaired Ulnar Nerve injuries. The completeness of flexion of the ring and little fingers was tested at the metacarpophalangeal and distal interphalangeal joints. Proximal interphalangeal joint extension lag of the ring and little fingers was assessed by goniometry, and adduction and abduction of the little finger. With dynamometers, I bilaterally evaluated grasp, key pinch, and pinch-to-zoom strength. Hand sensibility was evaluated with monofilaments. Results Metacarpophalangeal flexion in the Ulnar fingers was absent in all patients, whereas distal interphalangeal joint flexion was preserved in 29 of 30 patients. In above-elbow Ulnar Nerve injuries, there was no Paralysis of the flexor digitorum profundus. One-third of patients exhibited no clawing. There were minimal differences between the rate of clawing and proximal interphalangeal extension lag in above- and below-elbow Ulnar Nerve lesions, or its occurrence in the ring or little finger. In relation to the normal hand, grasping, key pinch, and pinch-to-zoom decreased by 62%, 51%, and 75% compared with 59%, 61%, and 76% in below- and above-elbow injuries groups, respectively. In both groups, sensory deficits were predominantly over the little finger and Ulnar side of the hand. Conclusions Minimal differences were observed in clinical deficits after above- and below-elbow Ulnar Nerve injuries. Hand weakness was the most frequent problem, whereas pinch-to-zoom strength was highly affected. Type of study/level of evidence Diagnostic IV.

  • restoration of pinch grip in Ulnar Nerve Paralysis extensor carpi radialis longus to adductor pollicis and abductor pollicis longus to first dorsal interosseus tendon transfers
    Journal of Hand Surgery (European Volume), 2003
    Co-Authors: T Fischer, Ladislav Nagy, U Buechler
    Abstract:

    A double tendon transfer was used to restore thumb pinch in nine consecutive patients. The extensor carpi radialis longus was transferred to the adductor pollicis tendon and one slip of the abductor pollicis longus was transferred to the first dorsal interosseus tendon. The patients were followed for 6 (range, 2–10) years and there were no instances of transfer rupture. Selective recruitment of the motors of the transfers was possible in all cases. Their amplitude was considered adequate for all the cases of adductor transfers but was limited in all of the first dorsal interosseus ones. Key pinch was 73% (range, 41–104%), the pulp-to-pulp pinch was 72% (range, 50–95%) and the power grip was 73% (range, 35–91%) of the opposite hand. The force of thumb adduction was 63% (range, 27–132%) and of index finger abduction was 58% (range, 21–104%) of the unaffected side.

  • bicycle rider s Ulnar Nerve Paralysis
    Minimally Invasive Neurosurgery, 1993
    Co-Authors: D Woischneck, S Hussein, H G Hollerhage
    Abstract:

    : The Ulnar neuropathy in bicycle riders is a less common occurrence, due to a local damage of the Nerve on the level of the Ulnar tunnel. It has been described in neurological literature only a few times, and hence its good prognosis is not sufficiently known. Within a short time two patients of this disease were transferred to our clinic for operation. After a local space-occupying growth in the tunnel could be excluded by MR or sonography of the wrist, we discouraged performance of an operative procedure. The patients' complaints and the neurological deficits vanished in a few weeks. Ulnar neuropathy in bicycle riders is therefore a syndrome for which even in the case of severe deficit an operation is not recommended.

  • Crossing Kirschner wires combined with double wire tension bands and screws in humerus intercondylar fracture
    Journal of Clinical Orthopaedics, 2020
    Co-Authors: You Chang-zheng
    Abstract:

    Objective To study the result of crossing Kirschner wires combined with double wire tension bands and screws in humerus intercondylar fracture.Methods 21 patients with intercondylar fractures of the humerus were treated with crossing Kirschner wires combined with double wire tension bands and screws through olecranon osteotomy.Results All patients were followed up for 6 months to 4 years.All got union in 3~7 months.The complications included 1 Ulnar Nerve Paralysis,3 lightly drawback of Kirschner wires.No infection and nonunion was found.According to the Aitkenand Rorabeek scoring system,7 were assessed as excellent,10 good,3 fair,and 1 poor.The excellent-good rate was 80.9%.Conclusions It has advantages of good exposure,simple manipulation,and rigid fixation in the treatment of humerus intercondylar fracture with crossing Kirschner wires combined with double wire tension bands and screws,which facilitates rehabilitation exercises and provides good results.
