Purpose: We report a series of 78 total hip arthroplasty revisions using a locked femoral stem, Ultime.

Material and methods: These patients presented aseptic loosening (88%) and septic loosening (12%). Fracture was associated in 17%. The preoperative Postel Merle d’Aubligné (PMA) score was 10.2 points. Using the Vives-SOFCOT classification, 29% of the loosenings were stage I, 37% stage II, 24% stage III, and 10% stage IV. All fractures were associated with lossening. We used a femoral window in 57% and trochanterotomy in 14 cases. The first eight patients in this series had an allograft (impacted piecemeal). Most of the patients resumed weight bearing the first week. The PMA score was used to assess outcome. AP and lateral views were used to evaluate stem-bone contact and cortical thickness at three levels.

Results: Early complications were phlebitis (n=1) and superficial haematoma (n=5). Late complications were dislocation (n=6), stem fracture (n=2), deep infection (n=3). At last follow-up, 81% of the aseptic loosenings, 77% of the septic loosenings, and 70% of the fractures on stem had a good or excellent PMA score with a mean gain of 4, 5, and 1 points respectively. Bone reconstruction showed an increase in internal cortical (2 to 4.4 mm) and stem-bone contact increased in the lower two-thirds of the stem. Allografts did not improve results. Furthermore, 28% of the patients had hip pain which could not be related to clinical findings or implant characteristics. Half of the patients were reoperated.

Conclusion: In this series, functional improvement was similar to that in published series. The femoral window facilitated the procedure and decreased intraoperative complications. The Ultime prosthesis met the objectives set by the manufacturer, i.e. primary stability and bone reconstruction authorising subsequent revision.

Purpose: We report a series of 32 ankle fractures reviewed 15 years after osteosynthesis.

Material and methods: The series included 12 fibular fractures, 14 bimalleolar fractures, and six trimalleolar fractures. The Weber classification was: type A four, type B 18, type C ten. Postoperative radiograpphy demonstrated 28 anatomic reductions and four shortened fibulae (3 to 5 cm). The results were assessed using the Harper criteria with a Kitaoka radiographic series. The statistical analysis was done with chi square.

Results: At the review 15 years after osteosynthesis, 19 ankles were pain free. Normal mobility was noted in 22 cases, and an absence of oedema in 18. Thirty patients wore normal shoes. Walking was normal in 23 cases; the x-rays revealed tibiotalar narrowing in 12 cases, and lengthenings of the malleolus in 23. Ten cases of tibiotalar narrowings were associated with a long medial malleolus. The objective results were good in 23 cases, fair in eight and poor in one. At fifteen years follow-up, osteoarthritis had developed in 37% of the cases despite anatomic reconstruction in 28. The four fibular shortenings were associated with development of osteoarthritis. Ossification of the medial malleola corresponded to detachment of a non-medial sutured ligament. Ankle osteoarthritis, when present, was particularly well tolerated.

Discussion: The long-term results of osteosyntheis for malleolar fractures was good in this series. Success requires perfect restoration of the joint anatomy. Unlike other series reported in the literature, non-surgical treatment of the medial collateral ligament led to medial periarticular ossifications in the very long term and limited joint mobility. We propose surgical suture of the medial collateral ligament.
