The purpose of this study was to identify changing trends in the pattern of distribution of the type and demographics of fractures of the hip in the elderly between 2001 and 2010. A retrospective cross-sectional comparison was conducted between 179 fractures of the hip treated in 2001, 357 treated in 2006 and 454 treated in 2010. Patients aged < 60 years and those with pathological and peri-prosthetic fractures were excluded. Fractures were classified as stable extracapsular, unstable extracapsular or intracapsular fractures.

The mean age of the 179 patients (132 women (73.7%)) treated in 2001 was 80.8 years (60 to 96), 81.8 years (61 to 101) in the 357 patients (251 women (70.3%)) treated in 2006 and 82.0 years (61 to 102) in the 454 patients (321 women (70.1%)) treated in 2010 (p = 0.17). There was no difference in the gender distribution between the three study years (p = 0.68).

The main finding was a steep rise in the proportion of unstable peritrochanteric fractures. The proportion of unstable extracapsular fractures was 32% (n = 57) in 2001, 35% (n = 125) in 2006 and 45% (n = 204) in 2010 (p < 0.001). This increase was not significant in patients aged between 60 and 69 years (p = 0.84), marginally significant in those aged between 70 and 79 years (p = 0.04) and very significant in those aged > 80 years (p < 0.001). The proportion of intracapsular fractures did not change (p = 0.94).

At present, we face not only an increasing number of fractures of the hip, but more demanding and complex fractures in older patients than a decade ago. This study does not provide an explanation for this change.

Proximal Metatarsal osteotomies are used for larger deformities, generally those with an intermetatarsal angle greater than 15°. These osteotomies usually are combined with a Distal Soft Tissue Release, which is necessary to correct metatarsophalangeal (MTP) sub-luxation with a Hallux Valgus Angle greater than 35°. Many types of osteotomies have been described. These include a medial opening wedge, a lateral closing wedge, proximal chevron, and a crescentic. Additional osteotomies include the Scarf, Ludloff, and Mao osteotomies. Presently, the proximal chevon and crescentic osteotomies are widely used.

In our study we used the proximal chevon osteotomy combined with Distal Soft Tissue Release and approximation of the 1^st and 2^nd metatarsus using a string to further decrease the intermetatarsal angle.

From January 2000 to June 2005 the basal chevon osteotomy was selected in 44 patients (37 female and seven male patients, ages 14 to 80, mean: 54.97 years) total of 49 feet with moderate metatarsus primus varus (IMA 13 to 20 degrees) and hallux valgus deformities (less than 50 degrees). The AOFAS Hallux Metatarsopha-langeal-Interphalangeal Scale and patient satisfaction were monitored prior to surgery, and postoperatively. Changes in the IMA and HV angle were measured in the conventional method and documented. All patients were treated in a Darco Post operative splint.

Results: Multiple complications were encountered. The most common is transfer metatarsalgia. This occurred in 10 patients (20%). Other complications include delayed union (4%), increase in the height of the first metatarsus (10%), floating toe (6%), superficial infection (15%), local parenthesis and early recurrence of deformity in 3%. 38 patients were available for follow-up. The hallux valgus angle improved significantly more than 20 degrees on average postoperatively. The intermeta-tarsal angle also improved significantly (more than 10 degrees on average) postoperatively. The position of the sesamoids was realigned to beneath the first metatarsal head and the metatarsal length remained essentially unchanged. The AOFAS score preoperatively was a mean of 75.64 with respect to pain, deformity, motion, disability, and cosmetic. The AOFAS score postoperatively was a mean of 94.55. The mean improvement was 18.91. About 95.45 percent (42/44) were satisfied and would recommend the surgery to a friend.

Conclusions: The basal chevron osteotomy combined with Distal Soft Tissue Release and realignment using a string is a technically demanding procedure and has multiple potential complications but provdes a reliable method with respect to stability, technical ease and satisfactory surgical outcome for correction of moderate and severe bunion deformity, both as a primary and revision procedure.

We performed electrophysiological studies on both legs of 52 children, aged from 3 months to 15 years, with idiopathic club foot. In only nine (17%) was no abnormality found. Isolated peroneal nerve damage was seen in 14 (27%). Abnormality of both peroneal and posterior tibial nerves was found in five (10%). Four patients (8%) had evidence of isolated spinal-cord dysfunction, whereas combined spinal-cord and peripheral-nerve lesions were seen in 14 (27%). Six patients (11%) had variable neurogenic electrophysiological patterns. In 13 patients in whom the studies were repeated neither progression nor improvement of the electrophysiological parameters was observed. Pathological electrophysiological findings were found in 66% of conservatively-treated patients. In the 43 patients treated surgically, all 16 with fair and poor results had pathological electrophysiological findings and 12 required further operations. Multiplicity of the pathological findings was related to the severity of the deformity of the foot; normal studies represent a good prognostic sign. Electrophysiological studies are useful in idiopathic club foot with residual deformities after conservative or operative treatment. Our findings support the theory that muscle imbalance is an aetiological factor in idiopathic club foot.
