Resection of the distal interphalangeal joint (DIJ) is a claw-preserving method for treatment of septic arthritis. This study presents the radiographic and histological findings of the surgically-treated area after resection of the DIJ using a plantar approach in seven German Holstein cows. Histological postmortem evaluation 439 to 710 days after surgery showed that there was extensive proliferation of connective tissue rich in collagen fibres in the space left after resection in three cows; this was classified as fibrous ankylosis. In the remaining four cows, histological evaluation 1010 to 1756 days after surgery showed extensive new bone formation in the joint cavity consistent with osseous ankylosis. Radiographs of the resected DIJ region obtained at the time of histological examination revealed no osseous ankylosis in two cows, partial ankylosis in one cow and complete osseous ankylosis in four cows. Formation of complete osseous ankylosis after resection of the DIJ did take longer than 1–2 years in three of our specimens indicating a longer time span compared to earlier studies.

远端指间关节切除术（DIJ）是一种保存脓肿性关节炎的保爪方法。这项研究显示了使用seven骨方法对7头德国荷斯坦奶牛进行DIJ切除后，手术治疗区域的放射学和组织学发现。手术后439至710天的组织学死后评估表明，三头母牛切除后剩下的空间中，富含胶原纤维的结缔组织大量增殖；这被分类为纤维性强直。在剩下的四头母牛中，手术后1010至1756天的组织学评估显示，在关节腔内广泛的新骨形成与骨性强直相一致。在组织学检查时获得的DIJ切除区域的X光片显示，两头母牛没有骨性强直，一头母牛发生部分性强直，四头母牛完全发生骨性强直。在我们的三个标本中，DIJ切除后完全骨性强直的形成确实需要超过1-2年的时间，这表明与早期研究相比，其时间跨度更长。
