Weightbearing AP and lateral views done preoperatively and postoperatively were used for the study. For each set of films, the following parameters were measured: on the lateral view; overall length of the calcaneus, lateral talometatarsal angle, lateral talocalcaneal angle, and the calcaneal pitch angle; and on the dorsoplantar view, the talometatarsal and talocalcaneal angle. In addition, the relative coverage of the talus by the navicular was described by an angular measurement based on the relationship of the center of the talus to the center of the navicular. The average improvements in lateral talocalcaneal angle (a reflection of hindfoot valgus) was 6.4 degrees when the long axis of the calcaneus was used and 6.8 degrees when the inferior surface of the calcaneous was used for the measurement. The lateral talometatarsal angle improved an average 11.3 degrees (from an average of 19.7 degrees to 8.4 degrees). The dorsoplantar talometatarsal angle (a measure of forefoot adduction/abduction) improved 15.8 degrees (preoperative average 26.8 degrees, postoperative average 11 degrees). The calcaneal pitch angle improved an average 10.8 degrees (preoperative average 3.2 degrees, postoperative average 14 degrees). The relationship between the talus and navicular was defined by an angular measurement based on the center of each articular surface before and after correction using this measurement. An average improvement of 26 degrees occurred in the alignment of these two articular surfaces.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 3","pages":"136-41"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19473522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this paper was to demonstrate the relative safety of each of the arthroscopic portal and Acufex external ankle distractor pin sites by measuring their proximity to the neurovascular structures surrounding the ankle joint. Six fresh cadaver specimens and 12 fresh-frozen, below-knee amputations were utilized for this study. An Acufex ankle distractor was applied using the standard technique. Anteromedial, anterolateral, anterocentral, posterolateral, and posteromedial portals were placed using an 11-blade scalpel to make 5-mm longitudinal incisions. The joint capsule was penetrated and a 3-mm arthroscope was placed into the ankle joint. The skin surrounding each of the portals was carefully removed and the proximity of any nerves or vessels was measured with respect to the arthroscope. At least one incidence of contact or penetration of a nerve or vessel was noted for each site. The anterocentral portal was at greatest risk for nerve or vessel damage. The anterolateral, anteromedial, and posterolateral portals were the safest areas for portal placement, with no penetration of neurovascular structures in any case.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 3","pages":"142-7"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400306","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19474151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The occurrence of more than one lesion of the nerve in the same limb is less frequent. Thirteen patients with 15 cases of tarsal tunnel syndrome associated with one or more additional lesions of the sciatic nerve or its branches of the same lower extremity are presented. Electrodiagnostic studies confirmed tarsal tunnel syndrome with conduction abnormalities at a number of locations along the sciatic, common peroneal, posterior tibial, or plantar nerves by mechanical impingement, metabolic axonal abnormality, or both. Seven of the 13 patients were treated with tarsal tunnel release. Six cases treated operatively improved significantly. Surgery on a previously operated foot or the existence of diabetes mellitus carried a fair prognosis. The association of back pain with or without previous surgery did not appear to affect the outcome of the tarsal tunnel release. No improvement in symptoms was apparent in the six unoperated patients during the period of the study. Multiple lesions of the nerves of a single extremity may account for the variable success rate of tarsal tunnel release.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 2","pages":"71-7"},"PeriodicalIF":0.0,"publicationDate":"1993-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400203","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19369603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gait analysis and the isokinetic maximum ankle torque test were performed in 20 patients with first to fourth degree traumatic ankle arthritis. Six patients without evidence of traumatic arthritis were used as controls. Isokinetic maximum ankle plantarflexion and dorsiflexion torques were determined with Cybex instrumentation. Force plate and foot switch data were gathered during level walking. Maximum ankle plantarflexion and dorsiflexion torques were diminished in the injured ankles. Velocity, stride length, and cadence were decreased in arthritic patients compared with controls. The arthritic limbs had shorter single limb stance and longer double stance during free and fast walking speeds compared with the controls' affected ankles. The patterns of ground reaction forces were similar in the injured and uninvolved limbs as well as the control subjects, except the magnitude of vertical forces during push-off were reduced in arthritic ankles. The gait parameters and muscle strength deteriorated as the arthritis became severe, but they showed significant changes only when the patients had third or fourth degree arthritis.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 2","pages":"97-103"},"PeriodicalIF":0.0,"publicationDate":"1993-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400208","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19436725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
