Diagnostic and clinical features of the frozen shoulder syndrome and the Sudeck syndrome are similar in many aspects. Radioisotope bone scan shows an increased uptake in affected areas in both diseases, while native radiographs show a progressive demineralisation. ⋯ In the immobilised control group with degenerative changes of the rotator cuff, calcifying tendinitis and shoulder instability (n = 12) and in the group of healthy probands (n = 20), the difference between the affected and non-affected side (left and right humerus of the healthy probands) was only more than 21% in one case each. There are several references in the literature that assume frozen shoulder to be an algoneurodystrophic process; our observations support this hypothesis, possibly leading to earlier diagnoses and extended therapeutic management.

Comparative StudyTibial shaft malunion treated with reamed intramedullary nailing: a revised technique.
Thirty-seven consecutive adult tibial shaft malunions which had not undergone surgical treatment were prospectively treated with reamed intramedullary nailing. Indications for this treatment modality included a malunion of a tibial shaft which had only been conservatively treated, lesion level fitting for traditional or locked reamed intramedullary nail fixation, less than 2 cm shortening, and without evidence of deep infection at present. The malunions were treated with fibulotomy, closed wedge tibial osteotomy, open reaming of the marrow cavity, stable reamed intramedullary nail stabilization with or without supplementation, and cancellous bone grafting. ⋯ Good exposure of the bony segments to ream the marrow cavity precisely can avoid cortical perforation. Gentle dissection of the soft tissues may lower the infection rate. Concomitant cancellous bone grafting can improve the union rate.

Case Reports Comparative StudyEvaluation of isolated fractures of the greater trochanter with magnetic resonance imaging.
The diagnosis of an isolated fracture of the greater trochanter can be done on routine radiographs, but this may not be the whole story. We evaluated fractures of the greater trochanter of the femur by magnetic resonance imaging (MRI). MR images were obtained within 5 days of the time of clinical presentation. ⋯ MRI showed that in seven of the eight cases, the fracture line was observed leading from the greater trochanter towards other trochanter regions. In only one case was the fracture limited to the greater trochanter and corresponded to the line observed on the standard radiographs. We suggest that in cases of greater trochanter fracture with somewhat severe symptoms, MRI should be performed in order to discover the appropriate diagnosis and treatment.

Comparative StudyCemented Lubinus and Furlog total hip endoprosthesis: a 12-year follow-up study of 175 hips comparing the cementing technique.
We analyzed 175 total hip replacements with cemented Lubinus and Furlong arthroplasties in 164 patients with a median age of 65 (32-80) years and followed them for 12 years to evaluate and compare the efficacy of total hip prosthesis designs. Survival analysis was combined with an analysis of radiological findings and a study of functional outcome of the patients. The 12-year survival of Furlong arthroplasty in patients of 60 years of age and older was O.85 (95% CI 1.00-0.52). ⋯ We conclude that cemented arthroplasty affords a notable alternative with satisfactory long-term survival and function. The better survival of cemented cup than the stem may be utilized as a basis for "reverse" hybrid arthroplasty. Adequate long-term follow-up of all arthroplasties as a quality maintenance and to prevent difficult revisions is a major challenge.

We report a case of a nerve sheath ganglion of the ulnar nerve at the canal of Guyon. This case involved a ganglion which was confined to the epineurium of the ulnar nerve. and it was completely excised without any damage to the nerve fiber. A nerve-sheath ganglion is rare, but it should be considered in the differential diagnosis of any tumor which is causing neural disturbance.
