In spite of the differences, there are many aspects of management where little disagreement exists. Anatomic reduction is the goal in situations where a primary salvage procedure is not performed. If closed treatment is chosen, careful follow-up is necessary to prevent unrecognized displacement as swelling subsides in the cast. Weight-bearing should be delayed until radiographic signs of fracture healing are obvious. There is a growing tendency toward open reduction and internal stabilization of talar neck fractures. Results suggest improved maintenance of reduction, decreased time to union, and a better end result. Prior to attempting any type of salvage procedure, careful assessment of both the tibiotalar and subtalar complex is necessary. The incidence of poor results following a talar neck fracture is disappointingly high. Additional studies of the pathoanatomy and biomechanics may improve our understanding. Controlled prospective clinical series will help clarify the advantages of specific treatment approaches and lead to better clinical results.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 4","pages":"225-34"},"PeriodicalIF":0.0,"publicationDate":"1993-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400409","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19344725","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}

Primary symptoms in patients suspected of having a neurologic basis for their heel pain include neuritic medial heel pain and radiation either proximally or distally. On physical examination, all patients in our series had reproduction of their symptomatology with palpation over the proximal aspect of the abductor hallucis and/or the origin of the plantar fascia from the medial tubercle of the calcaneus. Twenty-seven patients (20 women and seven men; average age 49) with these clinical characteristics were examined by electromyography and motor/sensory/mixed nerve conduction studies. Bilateral heel signs and symptoms were present in 11 patients. Ten of the patients had a significant history of back pain with referral to the legs. In 23 of the 38 symptomatic heels, abnormalities were identified in the lateral and/or the medial plantar nerves. The number of abnormal values per heel ranged from one to four, with a mean of 2.1. The most common finding was involvement of the medial nerve (57%). Thirty percent of the heels had isolated findings in the lateral plantar nerve and 13% had abnormalities in both plantar nerves. Two patients had electrophysiologic evidence of active S1 radiculopathy, with ipsilateral evidence of plantar nerve entrapment suggesting a \"double crush\" syndrome. The results of this study support the presence of abnormalities of plantar nerve function in a selected group of patients with neuritic heel pain.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 3","pages":"129-35"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400304","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19473521","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 loss of ligament support and alteration in the stability of the mortise have been postulated to lead to an increase in joint reactive forces and traumatic arthritis. The purpose of this study was to determine the changes in tibiotalar joint dynamics associated with syndesmotic diastasis as a result of the sequential sectioning of the syndesmotic ligaments to simulate a pronation-external rotation injury. Dissections were conducted on 10 fresh-frozen, knee-disarticulated cadaveric specimens which were then axially loaded in an unconstrained manner. Tibiotalar joint forces were measured at each level of sequential sectioning of the syndesmotic ligaments, the interosseous membrane, and finally the deltoid ligament. Complete disruption of the syndesmosis with the medical structures of the ankle intact resulted in an average syndesmotic widening of 0.24 mm and no significant change in the tibiotalar contact area or the peak pressure. However, deltoid ligament strain increases with sectioning of the syndesmosis. With the addition of deltoid ligament sectioning, there was an average syndesmotic diastasis of 0.73 mm, a 39% reduction in the tibiotalar contact area, and a 42% increase in the peak pressure. In a simulated unconstrained cadaveric model of a pronation-external rotation ankle injury that results in complete disruption of the syndesmosis, if rigid anatomic medial and lateral joint fixation is obtained and the deltoid ligament complex is intact, syndesmotic screw fixation is not required to maintain the integrity of the tibiotalar joint.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 3","pages":"153-8"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400308","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19474155","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}

Previously, we used autogenous dowels made from the iliac crest. In order to facilitate the operation and to get a better fitting dowel, we tried defatted cancellous allograft dowels from which marrow tissue had been removed. The dowels were prepared from femoral heads in our surgical bone bank. At operation, the dowels were embedded in fresh marrow aspirate from the iliac crest and the arthrodeses were stabilized with a staple. Results were evaluated by clinical examination and radiography. The results of four patients were compared with an earlier study of eight patients using autogenous dowels taken from the iliac crest. With both techniques, the patients were relieved of pain in the talonavicular joint, but some had pain from other hindfoot joints. With autogenous dowels, all eight patients healed with radiographic bony union, but with allogenous dowels, the four patients developed fibrotic nonunion. The results indicate that talonavicular arthrodesis should be made using only autologous dowels.","PeriodicalId":77133,"journal":{"name":"Foot & ankle","volume":"14 3","pages":"125-8"},"PeriodicalIF":0.0,"publicationDate":"1993-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1177/107110079301400303","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19473520","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}
