复杂中足损伤的临床治疗

Objective To evaluate the features and key points of clinical treatment of the complex midfoot injury retrospectively.Methods Twenty-two cases of complex midfoot injury were admitted to our hospital from June 2003 to June 2008, including 8 cases of open fracture and 5 cases of complicated soft tissue defects.Thirteen were emergency cases and the other 9 chronic ones were referred from other hospitals.In the emergency cases, only 1 underwent arthrodesis of the navicular and middle and lateral cuneiform and the others had reduction and internal fixation.In the referred cases, 2 received talar-navicular arthrodesis, 3 Lisfranc arthrndesis (accompanied by distal hallux amputation in 1), 1 navicular-cuneiform arthrudesis and 1 Chopart arthrndesis, 1 medial column amputation and 1 lateral column reconstruction.In the cases of soft tissue defects, 4 underwent free serratus anterior transfer, and 1 had transfer of distally-based sural fas-eio-cutaneous flap.The American Orthopaedic Foot & Ankle Society (AOFAS) scoring was used to evaluate the results.Results All the patients were followed up for 5 to 44 (average, 17.5) months.The main sequelae of the emergency cases were pain after long time waking, which was relieved following local injection of steroid and NIADs in 2 cases.Of the referred cases, pain and fatigue after walking were reported in 2, callus and pain under the 4th and 5th metatarsal heads in 2, and the whole foot rigidity and atrophy of the intrinsic muscle with severe pain while walking in 1.The case of medial column amputation developed medial arch collapse and valgus of hind foot.The mean AOFAS score for the emergency cases was 80.3± 8.7 and for the chronic ones was 60.1±16.3.Conclusion For complex midfoot injury, good results can only be obtained by early operation, anatomic reduction and stable fixation on the basis of enough understanding of the functional anatomy and traumatic pathology.

RETINOBLASTOMALACTIC DEHYDROGENASE OF AQUEOUS HUMOUR AND ITS ISOENZYMES

Lactic dehydrogenase (LDH) activity in aqueoushumour and serum was measured of 24 patients withretinoblastoma, senile cataract, glaucoma, and cho-roid melanoma in addition to LDH isoenzyme fractions. The results were compared with those of the20 normal children. The ratio of aqueous humourLDH to serum LDH was 4.32+2.80, and that ofisoenzymes LDH4 to LDHl was greater than l. Theresults of our study suggested that the total LDHactivity and isoenzyme fractions in the aqueoushumour is of value in the diagnosis of retinobla&toma.
