The management of patients with massive irreparable rotator cuff tears (RCT) has traditionally proved challenging. This prospective study was undertaken with the aim to assess the overall functional outcome following the use of human dermal allograft in the reconstruction of massive irreparable RCT. 15 patients were included in the study, having a median age of 63 years. All patients underwent open reconstruction of massive irreparable RCT. None of the selected patients had evidence of significant gleno-humeral arthritis. All patients were evaluated pre- and post- operatively by the treating surgeon, and followed up for 12 months. The same physiotherapy protocol was prescribed for all patients. Initial and follow-up assessments were done at regular intervals using the Oxford and quick-DASH scoring systems. A very high patient satisfaction rate, with substantial improvement in pain and function was noted. There was substantial improvement in Oxford shoulder score from a mean of 23.3 to 8.7 (p<0.01), and a similar improvement in mean quick-DASH score from 50.3 to 23.0 (p<0.01) Of the 15 patients, 11 had an improvement of >10 in Oxford score, with these reporting a score of <10 after 12 months. None of the patients had any significant complications because of the surgery, and none had a deterioration in Oxford score from their pre-operative status. We found that Human dermal allograft is a very effective tool in the repair of massive irreparable RCT, with excellent follow-up results after one year.
TGF-beta signaling has a well established role not only in adult organ homeostasis but also in skeletal development. Follistatin-like 3 (FSTL3), related to follistatin, is an inhibitor of TGF-beta ligands, with an established role in glucose and fat metabolism. However it has not previously been studied in skeletal development. Using a FSTL3 knock-out (KO) mouse model we have studied both embryonic skeletal development and adult bone phenotypes. Staining for skeletal and cartilage markers during development shows acceleration of skeletal tissue differentiation, with an eventual normalization at E18.5 (which is just prior to birth). Acceleration of bone mineralization occurs during both endochondral and intramembranous ossification. Use of micro-CT imaging highlighted the development of a scoliosis in the KO animals, along with abnormal shape of cranium and cranial sutures. Further investigation of the cranial phenotype in adult KO mice reveals craniosynastosis, with atypical fusion of the frontal suture. These mice have a change in overall cranial shape with shortening of the anterior head and a compensatory expansion of the posterior cranial bones, in a similar fashion to brachyencephaly. Our study therefore highlights a significant role of FSTL3 in skeletal tissue development and mineralization, as well as the development of clinically significant skeletal developmental disorders such as scoliosis, craniosynastosis and brachyencephaly.
Pre and post procedure pain and physical function scores were noted using the standard SF 36 questionnaire, as well as whether subsequent surgery was required. Mean follow up time was seven months (range 2–13 months).
A case of osteogenesis imperfecta, presenting with bowed deformity of both forearm bones and dislocation of the radial head was treated by separate elongation of both bones using Ilizarov's external fixator.
We report the results of 21 femoral osteotomies performed in 18 patients for genu recurvatum and flattening of the femoral condyles after poliomyelitis. Before operation the average angle of recurvatum was 31 degrees and all the limbs required bracing. After a mean follow-up of four years there has been partial recurrence in only one case. Nine patients (10 limbs) needed no orthosis and the others had less discomfort and an improved gait. Complete remodelling of the femoral and tibial epiphyses was noted in two of the younger patients.
