The commonest paralytic deformity in leprosy is the claw deformity of the fingers. Many surgical procedures have been described and are practiced to correct this deformity, but none is free from complications. A modification of the Zancolli lasso operation in which only half of the flexor digitorum superficialis tendon of the middle finger was used as the motor is described and a comparative study of this and the conventional procedure was carried out in 70 hands in 70 patients. The results suggest that the modification is technically simpler, with comparable results to those of the conventional procedure and fewer complications.

AbstractDuring routine dissection, bilateral multiple variations of forearm flexor muscles were observed in a male cadaver. The variations were a) an additional belly arising from the coronoid process of ulna, distal to the origin of ulnar head of flexor digitorum superficialis, passing deep to flexor digitorum superficialis and joining the tendon of flexor digitorum profundus to the middle finger; b) an additional belly arising from the distal part of flexor carpi ulnaris and passing superficial to ulnar nerve and ulnar vessels in the Guyon's canal and c) the origin of second lumbricals from the profundus tendon in the carpal tunnel. An aberrant muscle may stimulate a ganglion or a soft tissue tumor or if in close proximity to a nerve, it may cause pressure neuritis. Identification of these variations is important in defining the anatomical features for clinical diagnosis and surgical procedures.

Flexor Digitorum

The flexor digitorum superficialis is a digastric muscle with a proximal muscle belly from which the tendons to the index, ring and little fingers arise. These tendons are not independent and are not good motors for non-synergistic transfers. Such as for finger extension. The muscle and tendon to the middle finger arise separately and are therefore more suitable for non-synergistic transfers.

AbstractWe previously reported the beneficial effects of tendon transfer to eliminate extension lag of the interphalangeal joints, using the extensor carpi radialis longus prolonged by palmaris longus tendon grafts after crushing-penetrating injuries around the metacarpophalangeal (MP) joint of the middle finger. We used the flexor digitorum superficialis (FDS) as the alternative donor muscle and treated two cases of severe crushing injuries to MP joint, and then obtained good outcomes.

Despite a reduction in the maximal voluntary isometric contraction (MVCisom) observed systematically in intermittent fatigue protocols (IFP), decrements of the median frequency, assessed by surface electromyography (sEMG), has not been consistently verified. This study aimed to determine whether recovery periods of 60 s were too long to induce a reduction in the normalized median frequency (MFEMG) of the flexor digitorum superficialis and carpi radialis muscles. Twenty-one road racing motorcycle riders performed an IFP that simulated the posture and braking gesture on a motorcycle. The MVCisom was reduced by 53% (p < 0.001). A positive and significant relationship (p < 0.005) was found between MFEMG and duration of the fatiguing task when 5 s contractions at 30% MVCisom were interspersed by 5 s recovery in both muscles. In contrast, no relationship was found (p > 0.133) when 10 s contractions at 50% MVC were interspersed by 1 min recovery. Comparative analysis of variance (ANOVA) confirmed a decrement of MFEMG in the IFP at 30% MVCisom including short recovery periods with a duty cycle of 100% (5 s/5 s = 1), whereas no differences were observed in the IFP at 50% MVCisom and longer recovery periods, with a duty cycle of 16%. These findings show that recovery periods during IFP are more relevant than the intensity of MVCisom. Thus, we recommend the use of short recovery periods between 5 and 10 s after submaximal muscle contractions for specific forearm muscle training and testing purposes in motorcycle riders.
