A new method of transfer of the nasolabial skin flap, the myocutaneous flap with pediculated guadratus labii superioris muscle was introduced. It was applied in 9 cases mid-face defects with satisfactory results. The applied anatomy and the its operative technique were briefly discussed.
To fix the ligaments, tendons or other transplantation materials by passing through bone channels was commonly used and a relialde method in the reconstruction of joint stability. Usually an additional incision was necessary on the side of the outlet of the bone channel, that the screws, plates or U-shaped staple could be applied. An instrument was designed that the steel miniplate could be fixed to the bone by noninvasive method. This technique was applied in 20 cases in which anterior cruciate ligament in 14, posterior cruciate ligament in 4, and collateral ligaments in 2 with carbon fibers. The result was successful in all patients. It was shown that it gave simple manipulation, reliable fixation and no need to have an additional incision, and it could lessen patients’ suffering and lead to satisfactory clinical result.
Since February 1987, reconstruction of the brest by transposition of the contralateral half-brest with myocutaneous flap of pectoralis major muscle was used in 4 cases with successful results. The operation was suitable for those patients having radical mastectomy for early carcinoma of brest, and it was particularly feasible in those patients having benign lesions, trauma or other disorders causing absence of brest, and especially for those patients who had a huse brest of the contralateral side.
Four cases of defects of soft palate followingcomplete resection of soft palate because ofmalignant tumors had been successfullyreconstructed in which 3 patients wereperformed reconstructed with forehead flap andone patient with free forearm flap . All the flapewere survived. The appearance of the soft palateand function of swallowing were recoveredsatisfactorily from reconstruction. The operativetechnique of the reeonstruction of soft palate wasintroduced,and the points of attention ...
A total of 12 cases of old facet dislocations of cervical spine treated between december 1988 and 1993 were analyzed in order to evaluate the efficacy of various surgical modalities. In this series, there were 8 males and 4 females, with ages ranged from 16 to 50 years old (averaged 37.8 years old). The duration from injury to admission to our hospital was ranged from 1 to 8 months (averaged 3.7 months). Dislocation levels were as follows: C3,4 in 1 case, C4,5 in 4 cases, C5,6 in 4 cases and C6,7 in 3 cases. Unilateral facet dislocation was in 7 cases and bilateral facet dislocation in 5 cases. Neurological status on admission was as follows: spinal cord and nerve root lesion in 5 cases, nerve root lesion alone in 5 cases and neurologically intact in 2 cases. Besides all facets receiving facetectomy and iliac bone graft, other four kinds of adjuvant treatments were used, including internal fixation by stainless wires laminae or spinous processes in 4 cases, Luque rod in 1 cases, anterior fibrolysis combined with posterior laminoplasty in 1 cases and sustained skull traction without internal fixation in 6 cases. The reduction efficacy from postoperative stustained skull traction was better and the stainless wires fixation ranked the next. The patients only suffering from the nerve root lesion recovered better, but those who had spinal cord combined with nerve root lesion recovered badly. In conclusion, for the treatment of old facet dislocation, it is necessary to resect the facet and graft with iliac bone.
It is one of the difficult clinical problems to repair the large bone defect created by excision of benign tumors and to rebuilt the bone shelf. On the basis of the animal experiment, we excised thoroughly the effected bone subperiosteally and repaired the bone defect by fibula without its periosteum of other materials. The bone framework was successfully reconstracted. From Jan. 1984 to Dec. 1992, a series of seven cases were treated accordingly. The patients were followed up for 1 to 9 years. The skeletal framework in each was rebuilt rigidly. There was no recurrence and the functions of the extremity was recovered. In part of thesubperiosteum of fibula supplier bave regeneration of a new fibula with normal size at the site where the fibula was excised subperiosteally.
Objective To assess the long-time results of reconstruction of the extensor pollicis longus (EPL) function by transfer of the extensorindicis(EI). Methods From August 1978 to March 2003, 46 cases of loss of the EPL function were treatedby transfer of the extensor indicis. Of 46 cases, there were 32 males and 14 females, aged 16-51 years with an average of 36 years; there were 24 cases of oldtraumatic rupture and 22 cases of secondary rupture. The disease course was 2 days to 5 months, averaged 74 days. A specific EIEPL evaluation method (SEEM) wasused to measure the EPL function after transfer.Results Fortyone cases were followed up 9 years and 3 months on average (7 months to 23 years). Based on the SEEM, the results were excellent and good in 39 of 41 patients. The elevation deficit and combined flexion deficit were 0-2.2 cm (1.8 cm on average) and 0-3 cm (1.6 cm on average); the independent extension deficit was 0°-8° (5° on average). Conclusion Restoration of the extensor pollicis function by transfer of the extensor indicis is an effective and safe treatment option and the SEEM is a valid method for assessing EPL function.
From 1979 to 1994, reparative and recons tructive surgery were used to repair the war injuries of skins, bones, blood vessels and nerves of the limbs in 800 cases. A systematic clinical study was carried out. Many new operative methods were used and the results of treatment were good. Innovations and modifications were made in technique. In 120 cases of warin juries having soft tissues defects including skin and muscles, various tissue transplantations were used with the hope to accomplish onestaged repair of the defect and reconstruction of motor function of muscle. To those infections of bone and joint in war injuries, following early eradication of infected focus, transplantation of musculocutaneous flap or omental graft was immediately carried out with the aim to obtain primary healing of the wound. In the treatment of bone defects from war wounds with loss of skin and muscles, the vascularized skeletocutaneous graft was used. In the treatment of 150 cases of injury of peripheral nerve from forearms, the result of good to fair rated 68.8 percent for upper extremity and that for lower extremity, it was 62.2 percent. Following the early repair of 500 cases of injury of peripheral blood vessels, the patency rate of the blood vessel was 90 percent. The result following by pass vascular graft in the treatment of forearms injury of blood vessels even with very poor local condition was still very successful.
Objective To compare the long-term results of vascularised fibulargraft and simple autologous fibular graft for reconstruction of wrist after distal bone tumor resection.Methods From January 1979 to September2002, 15 patients with wrist defects due to distal bone tumor resection were treated with vascularised fibular graft or simple autologous fibular graft and followed up 1 year. The results were graded with Enneking’s system and evaluated radiographicallyaccording to the “International Symposium on Limb Salvage”. The grade system included limb function, radiological examination and the function of ankle. Results The limb function of 8 patients with vascularised fibular graft restored to 80% of normal function and the bone union was achieved within 6 months. The limbfunction of 6 patients with simple autologous fibular graft restored to 67% of normal function. The bony union was achieved within 6 months in 4 cases with thebone graft less than 5 cm and in the 13th and 16th months in 2 cases with the bone graft more than 12 cm. Conclusion It is suitable to use the headof fibular boneas a substitute for the distal radius. The healing of vascularised fibular graft is very quick and haven’t the bone resorption. So in the procedure for reconstruction and limb salvage after bone tumor resection of distal radius, the free vascularised fibular graft with fibular head is an ideal substitute.
OBJECTIVE: To observe the strength of thigh muscles after reconstruction of anterior cruciate ligament by autogenous bone-patellar tendon-bone graft. METHODS: Twenty-three patients, 9 males and 14 females, were followed up one year after reconstruction of the anterior cruciate ligament with autogenous bone-patellar tendon-bone graft. Through arthroscope, no intra-articular derangement was found. The strengths of isometric and isotonic contractions of the quadri ceps and the hamstrings muscles of the affected and contralateral thighs were recorded. RESULTS: The donor side for autogenous bone-patellar tendon-bone graft showed significant decrease (P lt; 0.01), but no effect on that of the hamstrings muscle(P gt; 0.05). CONCLUSION: To reconstruct the anterior cruciate ligament, harvest of the bone-patellar tendon-bone graft as a reparative material may markedly lower the strength of the quadriceps femoris muscle.
