Osteoporosis can cause significant disability and cost to health services globally. We aim to compare risk fractures for both osteoporosis and fractures at the L1-L4 vertebrae (LV) and the neck of femurs (NOFs) in patients referred for DEXA scan in the North-West of England. Data was obtained from 31546 patients referred for DEXA scan in the North-West of England between 2004 and 2011. Demographic data was retrospectively analysed using STATA, utilising chi-squared and t-tests. Logistical models were used to report odds ratios for risk factors included in the FRAX tool looking for differences between osteoporosis and fracture risk at the LV and NOFs. In a study involving 2530 cases of LV fractures and 1363 of NOF fractures, age was significantly linked to fractures and osteoporosis at both sites, with a higher risk of osteoporosis at NOFs compared to LV. Height provided protection against fractures and osteoporosis at both sites, with a more pronounced protective effect against osteoporosis at NOFs. Weight was more protective for NOF fractures, while smoking increased osteoporosis risk with no site-specific difference. Steroids were unexpectedly protective for fractures at both sites, with no significant difference, while alcohol consumption was protective against osteoporosis at both sites and associated with increased LV fracture risk. Rheumatoid arthritis increased osteoporosis risk in NOFs and implied a higher fracture risk, though not statistically significant compared to LV. Results summarised in Table 1. Our study reveals that established osteoporosis and fracture risk factors impact distinct bony sites differently. Age and rheumatoid arthritis increase osteoporosis risk more at NOFs than LV, while height and steroids provide greater protection at NOFs. Height significantly protects LV fractures, with alcohol predicting them. Further research is needed to explore risk factors’ impact on additional bony sites and understand the observed differences’ pathophysiology.

Anatomical reduction of the joint is the primary aim in the treatment of acetabular fractures as any other articular fracture. The current standard approach provides open reduction and internal fixation (O.R.I.F.) through a variety of surgical approaches which have been associated with relatively high complications rate such as haematomas, deep infection, and neuro-vascular lesions. These procedures need long operative times with significant blood loss. Many authors have demonstrated the feasibility of closed reduction and percutaneous fixation (C.R.P.F.) for minimally or non displaced acetabular fractures; this technique can be considered a valid alternative to O.RI. F. in order to decrease the morbidity related to surgical approaches. Between 2001 and 2006 we performed C.R.P.F. for acetabular fractures in 15 patients; the reduction has been controlled with fluoroscopy during the operation and with CT scan after the operative procedure. The osteosinthesis has been performed with cannulated screws and In more complex cases the reduction has been achieved and maintained with ileo-femoral external fixation (ligamentotaxis technique). Fractures were classified according to AO classification. Clinical and functional results have been evaluated according to Harris Hip Score on the base of post-operative CT scan and on x-ray films at last follow-up. According to our experience the use of external fixation in the treatment of acetabular fractures must be reserved for very selected cases in which for general or local condition the joint the distraction associated with minimal internal fixation can guarantee good reduction and fracture stability avoiding the poor results of conservative treatment or the risk of major complications related to ORIF. The best reduction can be achieved when the treatment is carried out early while the best stability is achieved with the association of percutaneous cannulated screws. The use of external fixation has never compromised the range of movement of the hip.
Distal osteotomy of the first metatarsal can be performed by a percutaneous minimally invasive procedure when indicated for the surgical treatment of hallux valgus. The intermediate-term results of percutaneous distal uniplanar osteotomy of the first metatarsal were assessed in 118 feet in 82 patients (36 bilaterally) to determine the effectiveness of the percutaneous procedure. A modified Lamprecht – Kramer – Boesh technique was performed under distal nerve trunk anaesthesia (ankle block) without a tourniquet, using a K-wire for stabilisation of the osteotomy. No surgical approaches and no soft-tissue procedures were required. Post-operatively adhesive tape was applied and immediate weight-bearing allowed. The patients were followed for an average of 36 months (range 24 to 78 months). Clinical assessment was based on the American Orthopaedic Foot and Ankle Society, hallux-metatarsal-phalangeal-interphalangeal (AOFAS) scale. Anteroposterior and lateral weight-bearing radiographs were performed pre- and post-operatively, and the hallux valgus angle, the first intermetatarsal angle, the distal metatarsal articular angle (DMAA) and the position of the sesamoid were recorded. The average score according to the AOFAS scale was 86.6±12.9. Patients were satisfied with the result of the procedure in 90.7% of cases. The results confirm the effectiveness of the percutaneous procedure to achieve a satisfactory distal osteotomy of the first metatarsal without the need for soft-tissue procedures in the surgical management of symptomatic hallux valgus.
Implantation of metatarso-phalangeal prostheses or spacers has been widely indicated for the replacement of the articular surfaces in severe hallux rigidus. Giannini proposed a reabsorbable device in poly(D-L-lactic acid) (PDLLA) which is dome-shaped with a stem for implantation into the first metatarsal, avoiding any resection of the base of the proximal phalanx. The rationale for the reabsorbable spacer is to maintain the distance between the articular surfaces for a predictable time and to provide a sliding surface suitable for articulation with the proximal phalanx. It is then reabsorbed by fragmentation and replaced by fibrous tissue, which maintains the articular space, allows motion and relieves pain. Twenty-three reabsorbable spacers have been inserted for severe hallux rigidus in 20 patients aged from 26 to 76 years (average 58). Patients were reviewed with a follow-up ranging between 24 and 50 months (average 36). The results were assessed using the American Orthopaedic Foot and Ankle Society (A.O.F.A.S), hallux-metata-tarsophalangeal-interphalangeal scale. Anteroposterior and lateral weight-bearing X-rays were made preoperatively and at follow-up, evaluating the dimensions of the articular space and the length of the first metatarsal. The chronology of device reabsorption was studied in 10 patients with M.R.I., assessing complete reabsorption within 4 months of the operation. Excellent and good results were obtained in 91% of patients. The A.O.F.A.S. score was 43.7±20.6 pre-operatively and 82±10.3 post-operatively. The reabsorbable spacer confirmed the expectations of its supporters. This procedure would appear to be an alternative to arthrodesis of the first metatarso-phalangeal joint or traditional permanent implants and represents an intermediate technique between an implant and resection arthroplasty.
