Category: Bunion Introduction/Purpose: Total arthroplasty or arthrodesis is often used as a surgical procedure for severe case of hallux rigidus. However, because these procedures involve problems such as loss of joint function, age, and postoperative motion restriction, joint-preserving surgery is desirable for achieving a better quality of life. To resolve these problems, we have performed dorsiflexion osteotomy of the first metatarsal head since 2000, yielding favorable outcomes. We report about middle to long-term follow-up for our clinical results and radiographic findings. Methods: The study involved 31 feet of 30 patients (20 male,11 female) with Grade 2 (joint space narrowed to about 1/2 or less) or Grade 3 according to the Hattrup and Johnson classification. The mean age at surgery was 61.6 years (range: 53-77). Surgical techniques: We have used dorsal approach and conducted closed wedge osteotomy of the first metatarsal bone neck. Then, the bone head was flexed dorsally to form an articular surface and fixation. PWB was permitted 3 weeks after surgery. Mean postoperative follow-up period was 4 years and 2 months (range: 3-13 years). Clinical outcomes, range of motion (ROM), and radiographic findings were investigated. Results: Clinical outcomes were rated as excellent in 24 feet, good in 7, and fair/poor in none. All patients returned to normal daily life. Stiffness while walking was noted in 10 feet. As for ROM, most patients had a 1/2 to 2/3 of the normal range. No complications such as infection, nonunion, or transfer metatarsalgia were seen in any case. An X-ray film showed joint space narrowing in about half of all cases. None of the patients experienced pain relapse requiring arthrodesis again. Conclusion: The mechanism of pain relief is Dorsiflexion osteotomy is by bone shortening, make a decreasing joint pressure and regaining of normal articular to the dorsal side so that it faces the articular surface of the proximal phalanx. The postoperative restriction of ROM may be attributable to changes in the bone alignment and in the tension of soft tissue around the joint as compared to the healthy condition. None of the patients experienced pain relapse. Our procedure appears to be useful as joint- preserving surgery for severe cases with hallux rigidus.

Background: Metal-on-metal hip resurfacing arthroplasty (MMHRA) is typically used in young and active patients because they have the most to gain from this bone-preserving procedure. However, there is very little long-term data on the performance of MMHRA in patients 65 years of age or older because of the efficacy of conventional total hip arthroplasty in this patient population. Methods: 109 patients (124 hips) age ⩾65 years were treated with Conserve Plus MMHRA. There were 83 male and 26 female patients. Their mean age at surgery was 69.5 (range 65–83) years. UCLA hip scores, SF-12 quality of life score were collected at follow-up visits. Radiographic and survivorship analyses were performed. Results: SF-12 scores and UCLA scores were maintained over time except for a small decrease in activity. 4 patients underwent revision surgery. The 15-year Kaplan-Meier survivorship of the cohort was 93.7%. All revisions surgeries were successful at a mean follow-up time of 113 (range 30–218) months. Unusual radiographic findings from our previous publication did not progress over time except for 1 hip that showed a complete radiolucency around the acetabular component. Conclusions: Our results clearly show that HRA is a viable prosthetic solution with many advantages for all active patients, regardless of their age at the time of surgery.

Aims The aim of this study was to report the long-term results of rotational acetabular osteotomy (RAO) for symptomatic hip dysplasia in patients aged younger than 21 years at the time of surgery. Patients and Methods We evaluated 31 patients (37 hips) aged younger than 21 years at the time of surgery retrospectively. There were 29 female and two male patients. Their mean age at the time of surgery was 17.4 years (12 to 21). The mean follow-up was 17.9 years (7 to 30). The RAO was combined with a varus or valgus femoral osteotomy or a greater trochanteric displacement in eight hips, as instability or congruence of the hip could not be corrected adequately using RAO alone. Results The mean Merle d’Aubigné clinical score improved significantly from 15.4 to 17.2 (p < 0.0001). The mean centre-edge (CE) angle improved from -2.6° to 26°, the mean acetabular roof angle improved from 3.0° to 5.2°, and the mean head lateralization index improved from 0.68 to 0.62. Progression of radiological osteoarthritis (OA) was seen in seven hips, but no patient underwent total hip arthroplasty. Conclusion RAO is an effective form of correction for a severely dysplastic hip in adolescent and young adult patients. Cite this article: Bone Joint J 2019;101-B:390–395.

Objectives (1) To develop an evaluation grid to provide a systematic interpretation of calves' articular radiographs, (2) to describe radiographic lesions of septic arthritis in dairy calves less than 6 months of age, (3) to investigate potential associations between demographic data or synovial bacteriological culture results and radiographic lesions (4) to determine whether an association is present between radiographic lesions, their severity and the long-term outcome. Methods Medical records of 54 calves less than 180 days old treated for septic arthritis between 2009 and 2014 with radiographic images performed in the first 2 days after admission were reviewed. Results Most common radiographic findings were increased articular joint space height (n = 49), irregularity of the articular surfaces (n = 24) and subchondral bone lysis (n = 24). The number of lesions observed and their severity were associated with older calves (p = 0.02), increased time between onset of clinical signs and admission (p = 0.0001) and the culture of Trueperella pyogenes within the joint (p = 0.02). The radiographic lesions associated with negative long-term prognosis were reduction in the joint space height (p = 0.01) and subchondral bone lysis on weight-bearing surfaces (p = 0.02). Clinical Significance An evaluation grid designed for veterinarians can facilitate systematic reading of articular radiographs and can be used for dairy calves with a presumptive diagnosis of septic arthritis. This diagnostic tool may aid in establishing a prognosis and decision-making process in terms of treatment.

Abstract The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Fourth Edition, provides methods to rate knee injuries treated by partial or total menisectomy and also provides methods to rate knee injuries treated by partial or total menisectomy. Although accompanying tables permit impairment rating of most knee injuries, arthroscopy and new surgical procedures have permitted early diagnosis of osteochondral fracture defects that are not easily rated. A peripheral meniscal tear in the fascular part of the meniscus potentially is repairable, but impairment rating after treatment is challenging. If the only surgical procedure was meniscal transplantation and if preoperative radiographs demonstrate joint space narrowing that is sufficiently significant to rate as an impairment, the knee probably can be rated using the joint space narrowing measurement and Table 62. The AMA Guides is silent about rating the impairment when an osteochondral fracture has occurred. If, after time for healing and rehabilitation, the joint has limited motion, atrophy in supporting muscles, or joint space narrowing on radiographs, the rating for those problems probably will adequately describe the impairment. Long-term results of operations that attempt to repair the meniscal or articular cartilage are not known, and impairment rating after one of these procedures may change with time and the publication of additional studies.
