Surgical reconstruction of irreversible ulnar nerve paralysis in leprosy

Twenty-five patients with irreversible leprotic ulnar nerve palsy having undergone lumbrical replacement with two different tendon transfer techniques were assessed 6-120 months after surgery. Nineteen patients were reconstructed with the flexor digitorum four-tail procedure (FDS-4T), and six with Zancolli's lasso procedure (ZLP). Mean paralysis times were 103 months for FDS-4T, and 68 months for ZLP. Mean age of the patients was 36 years (21-57). Grip strength measurements, improvement in active range of motion at the PIP joints, patients' ability to open and close their hands fully, as well as sequence of phalangeal flexion, were noted. Mean grip strength measurements during follow-up were 76% of the contralateral extremity in the FDS-4T group and 82% in the ZLP group. Comparison of the follow-up grip strength with the preoperative value revealed 1% improvement in the FDS-4T group and 20% in the ZLP group. Claw hand deformity was completely corrected in 12 patients in FDS-4T group, and in five patients in the ZLP group. Residual flexion contracture remained in five patients after surgery. Swan-neck deformity subsequently developed in seven fingers. Age, sex, mean follow-up and surgical technique did not relate statistically to the functional outcome. However, preoperative extensor lag of the PIP joint and mean paralysis time significantly affected the functional outcome. ZLP was found to be a more effective procedure in restoring grip strength, whereas FDS-4T was more effective in correcting claw hand deformity

Three tendon transfer methods in reconstruction of ulnar nerve palsy

Purpose: This study was designed to investigate the efficacy of 3 different tendon transfer techniques in restoring grip strength, correcting claw hand deformity, and improving hand function after irreparable ulnar nerve palsy

Restoration of sensibility in irreparable ulnar and median nerve lesions with use of sensory nerve transfer: Long-term follow-up of 20 cases

A prospective study was conducted to evaluate patient outcomes following sensory nerve transfer. Twenty patients with irreparable ulnar or median nerve lesions underwent the procedure. Nerve involvement was bilateral in 5 cases. The mean age of the patients at the time of surgery was 29 years. The mean paralysis time and the average length of follow-up were 59 and 78 months, respectively. Eighteen of 20 patients attended a sensory re-education program after surgery. Outcome was assessed objectively by functional sensory recovery testing and by the British Medical Research Council standards. Subjective outcome was assessed by a questionnaire. Two-point discrimination of less than 10 mm was achieved in 15 of 25 hands. The mean functional sensory recovery score was 83. Eighteen of 20 patients reported that the function of their hands improved after the procedure. Good or excellent results were associated with immediate transfer of the nerve, young age, and patients' attendance to the sensory re-education program after surgery. No differences were found between the recovery of ulnar and median nerves. Based on these results we suggest that sensory nerve transfer is a simple and reliable way of restoring sensibility to the hand with favorably comparable results over conventional nerve grafting in selected cases.

Brachioradialis re-routing for the restoration of active supination and correction of forearm pronation deformity in cerebral palsy

A brachioradialis muscle rerouting procedure was used to restore active supination in five children with cerebral palsy and a pronation deformity. Following release and lengthening of the pronator quadratus and pronator teres muscles, respectively, the brachioradialis tendon was divided as a Z plasty and the distal part of the tendon was passed through the interosseous space in a dorsal to palmar direction, and then sutured to its proximal end. The procedure resulted in a gain of 81degrees of active supination

Neuropsychological functions in idiopathic occipital lobe epilepsy

Purpose. Despite the benign prognoses of idiopathic partial epilepsies, particularly regarding the response of seizures to treatment, some evidence now exists that patients with such disorders may have subtle neuropsychological deficits. This study was designed to investigate several modalities of neuropsychological functioning in a group of 21 patients, ranging from 6 to 14 years of age, with idiopathic occipital lobe epilepsy (IOLE). The case patients were compared with 21 healthy controls matched for age, sex, and socioeconomic status

Comparison between sensitive and nonsensitive free flaps in reconstruction of the heel and plantar area

In this study, 12 cases of reconstruction of the heel and plantar area since 1982 are reviewed. Six nonsensate muscle fi ee flaps and six sensate fasciocutaneous flaps were used, respectively. Categories assessed were the time interval al for return to daily living activities, sensation to light touch, pinprick, Semmes-Weinstein monofilament test of the reconstructed area for sensory evaluation; and results of pedograms (maximal pressure, pressure distribution, and total contact area of the plantar surface). Follow-up periods were between 2 and 14 years, with an average of 6 years. Better sensory results and early return to daily living activities were obsen ed in the sensate flap group, hut the defects were smaller in this group. Despite the slightly longer time to return to daily living activities and worse sensory results, long-term follow-up showed that patients with nonsensate flaps had no difficulty in performing living activities if they continued to be careful and to use some kind of protective shoes. The results of the pedogram analyses were similar between the two groups with regard to total contact area of the reconstructed foot in relation to the healthy foot. Pressure values of the reconstructed areas in sensate flaps were found to be close to pressure values in the same weight ar-eas of the normal foot. The differences between pressure values of the sensate and nonsensate flaps were statistically significant (p < 0.001). Therefore, in reconstruction of the weight-bearing surface of the foot, each case should be evaluated individually. The reconstructive method should be chosen according to thr location and soft-tissue requirements of the defect
