Secure fixation of displaced proximal fractures of the humerus is a challenging problem. A total of 32 patients with acutely displaced three- or four-part proximal fractures of the humerus were treated by open reduction and internal fixation using the proximal humeral internal locking system (PHILOS) plate. There were 23 women and nine men with a mean age of 59.9 years (18 to 87). Data were collected prospectively and the outcomes were assessed using the Constant score. The mean follow-up was for 11 months (3 to 24). In 31 patients (97%) the fracture united clinically and radiologically at a mean of 10 weeks (8 to 24). The mean Constant score at final review was 66.5 (30 to 92). There was no significant difference in outcome when comparing patients aged more than 60 years (18 patients) with those aged less than 60 years (14 patients) (t-test, p = 0.8443). There was one case each of nonunion, malunion and a broken screw in the elderly population. This plate provides an alternative method of fixation for fractures of the proximal humerus. It provides a stable fixation in young patients with good-quality bone sufficient to permit early mobilisation. Failure of the screws to maintain fixation in the elderly remains a problem.

The purpose of this prospective study was to evaluate pain levels, range of motion, patient activity and satisfaction after radioscapholunate (RSL) arthrodesis. This was in association with distal scaphoid excision and complete resection of the triquetrum. The non-union rate for radioscapholunate arthrodesis was examined and the results compared with previous studies. Twenty-three patients (14 males and nine females) with an average age of 47 (range 26-73) years underwent RSL fusion for post-traumatic osteoarthritis, rheumatoid arthritis and Kienböck's disease of the lunate with a mean follow-up of 32 (range 13-70) months. The absolute prerequisite for any of these groups of patients was a functional midcarpal joint which was assessed pre-operatively with radiographs and intra-operatively prior to RSL fusion. The average flexion to extension motion changed from 66 degrees to 57 degrees . The ulnoradial range of motion also increased to 43 degrees from a pre-operative value of 22 degrees . The patients visual analogue pain scores reduced from an average of 64 to 28 (p = 0.01). Nineteen patients had no restriction in activity and all but one was satisfied with the outcome. All patients remained in full time employment with ten returning to some form of sport. RSL fusion with excision of the distal pole of the scaphoid and the entire triquetrum led to minimal reduction in the flexion-extension arc of motion and an increase in the ulnoradial arc. There was also good pain relief and maintenance of a patient's function. Memory staples are also an effective method of securing fusion in the wrist obtaining similar results to that seen in forefoot surgery.

Background. Dysplasia epiphysealis hemimelica (DEH) is rare and its main characteristic is osteochondromas of the epiphysis of long bones. Methods. We report a case of DEH of the ankle in an 8-year-old boy that was resected in 2005. Additionally we collect all the reported cases of DEH. The literature is reviewed regarding the treatment, prognosis, long term function, and patterns and areas affected by DEH. Results. In our case no complications were noted and our patient remains asymptomatic. Reviewing the literature we found that 73 authors have reported 144 cases from 1926 to 2013. We propose and describe a new classification that correlates with prognosis. According to our classification DEH is classified as types 1 with single lower limb involvement, 2 with multiple lower limb, 3 with single upper limb, 4 with multiple upper limb, 5 with upper and lower limb, and 6 with spine. Conclusions. All single lesions should be followed up and if indicated a whole body nuclear bone scan can be useful in identifying the existence of multiple affected joints. Type 1 lesions have better prognosis than 2 and have less chances of developing OA even if not resected. Resection, even if partial, can be a successful treatment for DEH.
