Case ReportsIsolated palmar dislocation of the distal radioulnar joint in a football player.
Palmar dislocation of the distal radioulnar joint without concomitant fracture of the radius or ulna is an uncommon injury. We report one case in a college football player. This case was unusual in that open reduction was required 2 days after the injury because of an unsuccessful closed reduction.

Shockwave application in calcifying tendinitis of the shoulder--prediction of outcome by imaging.
This prospective study examined 62 patients (65 shoulders) with chronic courses of calcifying tendinitis of the shoulder before and after low-energy extracorporeal shockwave application (ESWA) in order to identify variables associated with the outcome of this treatment. Before ESWA, radiographs and contrast-enhanced magnetic resonance imaging (MRI) of the affected shoulders were obtained in order to document the size and morphology of the calcifications and the contrast media reactions in areas of interest (deposit, synovia, bursae), respectively. In addition, a clinical evaluation was performed. ⋯ In 5 cases (7.7%), surgery of the affected shoulder during the follow-up period was performed. No major side-effects were seen in the study group. In conclusion, our results suggest that in patients with chronic calcifying tendinitis, the absence of contrast enhancement, especially around the deposit, is a strong predictive parameter of a positive clinical outcome of ESWA.

Comparative StudyAnterior versus posterior plating in cervical corpectomy.
This is a prospective study comparing anterior and posterior plating in cervical corpectomy. Each group comprised 30 patients who were candidates for corpectomy. In the first group, anterior plating was done using Orosco-type titanium plates. ⋯ The difference between the incidence of screw loosening in both groups was not statistically significant (chi-square = 0.35, p = 0.5). Sinking-in of the cage was encountered in 7 cases with anterior plating and in only 3 cases with posterior plating. However, the difference between the groups was not statistically significant (chi-square = 1.92, p = 0.16).

Case ReportsHypoplasia of bilateral humeral trochlea associated with bilateral ulnar nerve palsy.
We document a case of bilateral ulnar nerve palsy that developed in an 27-year-old Japanese man who had bilateral hypoplasia of the humeral trochlea. Surgical management produced good results regarding the ulnar nerve palsy. ⋯ There have been no reports outside Japan. Whether this deformity occurs only in persons of Japanese extraction or is simply overlooked by foreign surgeons is an interesting question.

Comparative StudyBipolar versus total hip endoprosthesis: functional results.
Some functional parameters of the hip-joint 3.3 years on average (range 2-8.6 years) after hip arthroplasty are compared with regard to two types of hip endoprostheses: the total (TEP) and the bipolar (BPEP). Flexion, extension, abduction, adduction, and internal and external rotation were measured for 75 patients with BPEP type Self-Locking, for 11 patients with BPEP type Vario-Cup, and for 43 with TEP type Lubinus. ⋯ It was found that flexion, abduction and adduction were significantly higher in the BPEP endoprosthesis (P < 0.05). The results obtained are favourable for the bipolar hip endoprosthesis, and they can be related to the biomechanical differences between both types of hip endoprosthesis.
