Objective To find out the recent progress in research of cl inical appl ication of fascia lata allograft. Methods The domestic and international articles were reviewed to summarize the princi pal properties, processing techniques, and various uses of fascia lata allograft. Results Histologically fascia lata is composed of parallel and compact bundles of collagen fibers with few cells and immunologically it is low-antigenic. After varied tissue processing and storage techniques, fascia lata, as the scaffold only with the extracellular matrix, has been used in cl inical practice and achieved good results, such as ophthalmology, urology, and orthopaedics. Conclusion Because of these unique properites in repairing defects and reconstructing functions, fascia lata allograft, as a natural biomaterial, is promising to be used in more aspects withthe development of the biomedical techniques.
The origin of blood supply and the features of vascular distribution of the fascia lata was obeervedby the method of microsurgical anatomy.It was found that there were 4 sources of the blood supplyfor the fascia lata. The blood vessels in the anterior supperior femoral area were from the original partof the decp femoral artery,while in the inferior part,the arteriess were from the tributary of theperforating artery. The blood vessels in the poterior superior femoral area were from both t...
he fascia lata substitute valve operation was performed for curing the supperficial varieositycaused by the deep vein incompotence of the lower extremity basing on the study of the sources ofblood supply and the vascular distribution features of the fascia lata. The fascia lata subetitute vein valve operations were done on three males with the age rangingbetween 22 and 44 years old, and the rerelts were satisfactory 2 and 6 months after oporation.
Repair of 11 cases of large surface wounds on hands and forearms was reported sucecessfully by using vaseulariged free fasciae late flap.The advantagca of the flap were :(1) The fasciae late was long,tenacious and its inner sutface smooth,it benefited the gliding of the tendon when if was used to cover the joints, bones and tendons, so it was a good material in repairing the surface wounds on hands and forearms;(2) The defects of tendons and skin could be repaired by using fasciae late flap at the same time; (3) The lateral femoral cutaneous nerve was long and thick with abundant branches, so it was best supphy and provided large amount of donor material for repair.
ObjectiveTo investigate the effectiveness of anterolateral femoral flap in combination with fascia lata grafting in repair of large Achilles tendon and skin defects.MethodsThe clinical data of 18 patients with large Achilles tendon and skin defects repaired with anterolateral femoral flap in combination with fascia lata grafting between January 2018 and January 2019 were retrospectively reviewed. There were 14 males and 4 females; age ranged from 32 to 57 years (mean, 42.1 years). There were 9 cases of postoperative infection of Achilles tendon rupture, 1 case of traffic accident injury, and 8 cases of combined infection of skin and Achilles tendon defects after heel trauma. The length of Achilles tendon defect was 4-8 cm, with an average of 5.6 cm; the range of the skin defect was 14 cm×3 cm to 20 cm×5 cm. Flap survival was observed, and ankle function recovery was evaluated according to McComis functional assessment criteria, and dorsal extension and plantar flexion mobility of the affected limb were measured at last follow-up and compared with those of the healthy side.ResultsEighteen cases were followed up 8-24 months, with an average of 16.7 months. All the flaps survived after operation, the flaps were soft and elastic, and the incisions healed by first intention. At last follow-up, 15 cases were excellent, 2 cases were good, and 1 case was acceptable according to McComis functional evaluation criteria, with an excellent and good rate of 94.4%. The two-point discrimination of the heel posterior region of the affected foot was 4-7 mm, with an average of 5.32 mm. The heel-raise test was negative. The dorsiflexion range of the affected side was (21.55±1.26)°, which was significantly different from that of the healthy side (25.23±1.45)° (t=8.128, P=0.000); the plantar flexion of the affected side was (44.17±1.52)°, which was not significantly different from that of the healthy side (46.13±1.31)° (t=0.444, P=0.660).ConclusionThe application of anterolateral femoral flap in combination with fascia lata grafting for the repair of large Achilles tendon and skin defects can achieve good effectiveness.
Objective To observe and evaluate the short-term effectiveness of superior capsular reconstruction using autologous fascia lata graft for irreparable massive rotator cuff tears. Methods The clinical data of 9 patients with irreparable massive rotator cuff tears treated with arthroscopic superior capsular reconstruction by using autologous fascia lata graft between September 2019 and April 2020 were retrospectively analysed. There were 4 males and 5 females with a median age of 66 years (range, 55-70 years). The disease duration was 6-60 months with an average of 19.1 months. According to Hamada classification, the patients were classified as grade 1 in 2 cases, grade 2 in 2 cases, grade 3 in 2 cases, and grade 4 in 3 cases. Before and after operation, the visual analogue scale (VAS) score was used to evaluate the improvement of shoulder joint pain, the American Shoulder and Elbow Surgeons (ASES) score, Constant score, and the University of California Los Angeles (UCLA) shoulder function score were used to evaluate the improvement of shoulder joint function. The active range of motion of shoulder joint was recorded, including forward flexion, abduction, lateral external rotation, and internal rotation. The changes of subacromial space were recorded by anteroposterior X-ray film of shoulder joint. Sugaya classification was used to judge the integrity of rotator cuff immediately after operation and at last follow-up. ResultsThe operation time was 210-380 minutes, with an average of 302.3 minutes. All incisions healed by first intention after operation, and there was no complication such as infection and nonunion of incisions. Two patients had numbness of the upper limbs on the surgical side after operation, and the numbness completely relieved at 6 weeks after operation; 5 cases with preoperative pseudoparalysis symptoms recovered after operation. Nine patients were followed up 12-17 months, with an average of 14.1 months. At last follow-up, the patient’s active range of motion of shoulder joint (forward flexion, abduction, lateral external rotation, and internal rotation), subacromial space distance, VAS score, ASES score, Constant score, and UCLA score significantly improved when compared with preoperative ones (P<0.05). There was no significant difference in the Sugaya classification between at last follow-up and immediately after operation (Z=−1.633, P=0.102). ConclusionSuperior capsular reconstruction using autologous fascia lata graft can restore the superior stability and achieve a good short-term effectiveness for irreparable massive rotator cuff tears.
