Common peroneal nerve injury has been reported as the most frequent lower extremity peripheral nerve injury. The peroneal nerve may be particulary prone to direct or indirect injury by penetrating trauma or external compression by it's superficial route to bony prominence of fibular neck. By the development of microsurgical technique, recently epineural repair, fascicular group repair, and interfascicular graft were tried. The authors have experienced five cases microsurgical repair of common peroneal nerve injury around the knee joint from December 1990 to November 1991, and motor and sensory result was relatively good.

Since the first experimental nerve graft by Philipeaux and Vulpian in 1870, many successful graft have been reported by Bunnell, Boyes, Millesi, Sunderland and Seddon. Advances in microsurgery techniques prompted Millesi to introduce the concepts of interfascicular nerve grafting whereby groups of fascicles, and not whole nerve, are connected together. Hunt and Taylor described a free vasculized nerve graft with microvascular anastomoses and obtained rapid axonal advance and maturation of grafted nerve in a clinical case. It is true that a nerve graft should be inferior to an end-to-end nerve repair, because in the case of nerve grafting the axon have to cross two suture lines instead of one. On the other hand, nerve grafting is indicated whenever a significant gap is produced in a nerve as a result of injury. In a retrospective study of 46 patients, defect of the nerve with treated by nerve graft were analyzed from March, 1983 to January, 1993 and following results were obtained. 1. Nerve graft was useful method to repair nerve whenever a significant gap is produced in a nerve as a result of injury. 2. The sural nerve was used as a donor nerve and vasculized nerve graft can be useful. 3. Postoperative results of cases caused by electric burns were worse than others. 4. There were little significant value in the treatment results between epineural and perineural nerve graft. 5. Recovery of intrinsic function in median and ulnar nerve lesion above the elbow was poor and recovery of the intrinsic function in median nerve graft at the forearm level was better than level for lesion in the ulnar nerve at the same level.

During January 1975 to December 1979, myelographic studies followed by operation was carried out on 150 cases of lumbar H.I.V.D. at Chung Nam National University Hospital. As to the myelographic findings, mode, level of indentation, and positive and negative finding were analyzed in comparison with operative findings. The followings results were obtained: 1. Plain radiography has a Iittle value In diagnosis of Iumbar H.I.V.D. about one third of 150 cases show significant sign in plain film study. 2. The major discrepancies between myelographic and operative findings were found in 11.3%, while the minor discrepancies were 4%, so giving an accuracy of 84.7%. 3. Positive myelographic finding(120 cases) consisted of smooth round defect in 83 cases (48.8%), unilateral wedge defect In 45 cases (26.4%), block defect In 18 cases (10.5%), bilateral wedge defect in 13 cases (7.6%), and hourglassdefect In 11 cases (6.4%), respectively. 4. Operative findings revealed the protruded disc: 74.5%, bulging: 11.1%, extruded: 22%, and mlgrated: 1.7%. 5. The myelographic finding of bulging type disc usually showed smooth round filling defect and those of protruded were smooth round filling defect, wedge shape and block filling defect, while the extruded type revealed smooth round filling defect In the most cases. 6. The myelography can be a valuable aid in the determination of the level and degree of H.I.V.D. and very helpful ln differential diagnosis.

Reliable and valid evaluation of hand strength is of paramount importance in determining the effectiveness of various normative data area needed to interpret evaluation data, to set realistic treatment goals and to assess a patient's ability to return to employment. The primary purpose of this study was to establish normal value of grip and pinch strength for men women in normal Korean adult. A Jamar dynamometer(Hydraulic Hand Dynamometer. PC 5030, USA) was used to measure grip strength and Jamar pinch gauge(Hydraulic Pinch Gauge, PC 5030HPG, USA)was used to measure tip, key and palmar pinch. Two hundreds forty eight male and two hundreds thiry one female adults, aged 20 to 74 years were tested for using standardized positioning with their shoulder adducted and neutrally rotated, elbow flexed at 90。 and the forearm and wrist in neutral position. Right and left hand data were stratified into age groups for both sexes. This stratification provides a means of comparing the scores of individuals to that of normal subjects of the same aged and sex. The following results were obtained; 1. The average grip strength of the dominant hand was highest(43.9±7.3kg)in 3rd decade male group. 2. The average tip pinch strength of the dominant hand was highest in 4th decade(7.3±3.5kg)and 5th decade (7.3±2.4kg) male group. 3. The average key pinch strength of the dominant hand was highest in 5th decade(8.3±2.3 kg)male group. 4. The average palmar pinch strength of the dominant hand was highest in 4th decade(9.6±3.3 kg)male group. 5. A high correlation was seen between grip strength and age, but a low correlation between pinch strength and age. 6. The average grip strength of dominant hand was 5.6% higher than that of nondominant hand in men, and 6.5% higher in women. 7. In pinch strength, palmer pinch strength was highest among the three groups of pinch strength, then key pinch and tip pinch strength in order. 8. The mean scores of the dominant hand were larger than that of the nondominant hand on all hand strength.
