Radiographic changes of the mid-tarsal joint at a minimum follow-up of 5 years after calcaneal lengthening for planovalgus foot deformity

Surgical correction was performed on nine patients who had equinovarus deformity caused by severe crush injury of the leg sustained in an earthquake. The operative procedure used involved the transfer of the posterior tibial tendon to the dorsum of the foot by passing it through the interosseous membrane using a modified procedure as published in 1978. 5 This procedure was combined with percutaneous Achilles tendon lengthening and tenotomy of toe flexors when needed. The average follow-up time after the operation was 21 months. The treatment improved the heel-toe steppage gait in all patients and all were able to walk in standard shoes. There were no complications in the postoperative period. Recurrence of varus deformity was not seen in any of the patients. They had active dorsiflexion of the foot, with a median active dorsiflexion of 5° (0 to 10°) and median active plantarflexion of 16.1° (10 to 25°) compared to the median active dorsiflexion and plantarflexion on the uninvolved side. The total range-of-motion was 21.1° (10 to 35°).

Case summary A 10-year-old neutered male domestic shorthair cat was diagnosed with renal adenocarcinoma associated with hypertrophic osteopathy. The cat was referred for chronic ambulation difficulties. The physical examination showed a painful thickening of all four limbs, a right cranial abdominal mass and a conjunctival hyperaemia. Radiographic findings were consistent with extensive periosteal new bone formation involving not only the diaphyses of the fore- and hindlimbs, but also of the pelvis, tarsus and carpus. Abdominal ultrasonography and CT revealed a mass within the right kidney and a primary neoplasm was suspected. A ureteronephrectomy of the right kidney was performed and histopathology confirmed the diagnosis of renal adenocarcinoma. Although clinical improvement of the lameness occurred after surgery, no radiographic changes of hypertrophic osteopathy lesions were observed at the 9-month follow-up. Relevance and novel information Feline cases of hypertrophic osteopathy are rarely reported in the literature and only a few of them were associated with abdominal neoplastic diseases. To our knowledge, this is the first case of renal adenocarcinoma associated with hypertrophic osteopathy in a cat.

SUMMARY:The preliminary results based on a three year retrospective study in cavus foot deformity of forty-four Friedreich ataxia patients regularly seen at the Neuromuscular Disease Clinic of Sainte-Justine Hospital have been presented. An accurate “weight-bearing” foot stereoradiographic technique has been recently developed by our group. Since the follow-up period with this device is not sufficient to provide statistical information, the conventional non-weight bearing technique has been utilized in this study to enable a possible comparison between the radiographs of ambulant and non-ambulant patients. Due to the present technique, the results of this study must be interpreted with caution.For 132 pairs of radiographs, 28 parameters have been analyzed. Four of these, namely the calcaneal inclination angle, the first metatarsal inclination angle, the inferior cortex of calcaneus-first metatarsal angle and the first-fifth metatarsals angle, were of particular interest. From these parameters, a preliminary quantitative description of cavus foot deformity in Friedreich’s ataxia has been attempted. Three stages of evolution have been tentatively identified for this type of neurological disorder.

Case summary A 15-week-old kitten presented with a 1-month history of intermittent generalised tremors and abdominal distension. Hypocalcaemia associated with increased 1,25-vitamin D3 was consistent with vitamin D3-dependent rickets type II. The bone appearance on CT scan was most consistent with the changes typically seen with nutritional secondary hyperparathyroidism and less typical of the changes seen with rickets. Our patient had a positive response to high vitamin D3 therapy as it remained normocalcaemic 16 months after diagnosis, supporting the diagnosis of rickets. Relevance and novel information This case report is an unusual and interesting presentation of rickets in a kitten. Despite the characteristic vitamin D3 disturbance for rickets type II, the atypical radiographic changes have not been previously reported. In the literature, a positive response to treatment is not commonly seen or follow-up is short. Our case responded well to treatment and was followed for 16 months from the time of diagnosis. This emphasises that the pathophysiology of the condition is not well understood, and that different types of vitamin D3-dependent rickets type II may exist. Although the genetic defects responsible for some cases of rickets type I have been identified, this has still not been determined for rickets type II.

In the 1980s, uncemented prostheses were considered advantageous in younger patients. One of the prostheses used in Denmark was the Porous Coated Anatomic (PCA) prosthesis. Follow-up results from Aarhus University Hospital (AaUH) showed progressive osteolysis along the stem at five to seven years, and use of the prosthesis was no longer recommended. We used the PCA prosthesis with a modular 28mm head, and so far our results with patients operated on between 1989 and 1993 do not confirm the negative results published. Thirty-nine consecutive cases were followed prospectively with clinical and radiographic assessment. At the 8–12 year follow-up four patients had undergone revision. Three revisions were for aseptic loosening of the cup at 5, 10 and 12 years, and one was because of thigh pain without radiological signs of loosening at revision. The cumulative survival rate was 95% at five years, 92% at ten years and 85% at twelve years. If we include radiologically loose components, five cups were re-operated or radiographically loose (12.8%) and 4 stems were re-operated or radiographically loose (10.2%). Thus the survival rate at 12 years was 85% and 90% for cup and stem respectively. So far we have not experienced progressive radiographic changes. The difference in results may stem from the fact that we used 28mm heads (versus 32mm heads in the Aarhus series), which allows a more adequate polyethylene thickness and thereby lesser creep of the polyethylene and less polyethylene debris production.

Category: Midfoot/Forefoot Introduction/Purpose: To compare the clinical result of midfoot and metatarsal dorsal wedge osteotomy for the treatment of cavovarus foot deformity in adolescents. Methods: A comparative retrospective study of 24 patients with cavovarus foot deformity in adolescents was conducted between March 2012 and March 2015 in the Guangzhou Orthopaedic Hospital. All patients were flexible deformity. 10 patients were treated with midfoot dorsal wedge osteotomy, while 14 patients received metatarsal dorsal wedge osteotomy. The clinical curative effects, complications and image differences were compared between the two groups. American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and Visual Analogue Scale (VAS) score were evaluated for each patient during the follow-up. All statistics were analyzed using the SPSS software system. Results: No early stage soft tissue complications occurred in all patients. All the patients obtained an average 21.5 months (ranged,10-30 months) follow-up.X-ray demonstrated that bone healing was obtained, the midfoot dorsal wedge osteotomy group at an average of 11.2 weeks (ranged,10-13 weeks). the metatarsal dorsal wedge osteotomy group at an average of 13.4 weeks (ranged,12-15 weeks). By AOFAS foot score and VAS pain score: There is no significant difference between the two groups (P=0.138). No complications of nonunion, recurrence of de-fortuity or implant failure were seen during follow-up. Conclusion: The midfoot and metatarsal dorsal wedge osteotomy are the effective methods for the treatment of cavovarus foot deformity in adolescents. For severe deformity midfoot metatarsal dorsal wedge osteotomy can provide more powerful correction.

Radiographic Changes

Abstract Introduction Stemmed humeral implants have represented the gold standard in total shoulder arthroplasty (TSA) for decades. Like many other joints, the latest trends in TSA designs aim at bone preservation. Current studies have demonstrated that native proximal humeral bone stresses are most closely mimicked by stemless implants. Nevertheless, there are concerns about the long-term performance of stemless designs. The aim of the present study was to evaluate the long-term radiographic changes at the proximal humerus in anatomical stemless press-fit TSA. Materials and Methods Between 2008 and 2010, 48 shoulders in 43 patients were resurfaced using an anatomic stemless shoulder prosthesis (TESS, Biomet). Thirty shoulders in twenty-five patients who were aged 65.7 ± 9.9 (34 to 82) years were available for clinical and radiographic review at a mean follow-up of 94.0 ± 8.9 (78 to 110) months. Results Radiographic changes of the proximal humerus due to stress shielding were found in 38.4% of the stemless TESS implants. Mild stress shielding accounted for 80% of the observed radiographic changes. Radiographs exhibited stable fixation of the stemless humeral press-fit implant at early and late follow-up. In contrast, radiolucent lines at the glenoid implant were found in 96.1% of the cases. Irrespective of the degree of radiographic changes, clinical scores (VAS, Quick-DASH, Constant score) significantly improved at follow-up. Conclusions The anatomic stemless press-fit implant seems to be favorable in terms of implant-related stress shielding. Clinical outcome was not affected by radiographic changes, demonstrating an 8-year clinical performance that seems to be comparable to conventional stemmed TSA.
