Case ReportsReactions and complications after the implantation of Endobon including morphological examination of explants.
In the study described here, the integration of hydroxyapatite (HA) ceramic implants (Endobon) was investigated. These implants have an interconnecting system of pores and are free from foreign protein. The material is not toxic, genotoxic, nor zytotoxic, and it is biocompatible. ⋯ If the implant is not sufficiently protected from mechanical stress, bony integation will not take place, and the implant may fracture. HA ceramic, with a porosity between 30% and 80%, is not comparable to cortical bone but only to spongy bone. This factor must be taken into account when deciding whether a HA ceramic implant is indicated.

Case ReportsSwelling of the dorsum of the hand and/or foot can be a first sign of Maffucci syndrome.
The cardinal feature of Maffucci syndrome is the coexistence of enchondromatosis and vascular anomalies. The patients are usually normal at birth, the disease becoming evident at any time up to puberty. Association of soft-tissue swelling has been described in this syndrome but has not been listed as a sign or symptom. ⋯ The pathology of the swollen soft tissue was adipose tissue associated with various degrees of thickened and fibrotic septum containing dilated lymphatic channels. These dilated channels within the septum were so subtle that they were initially overlooked in cases 1 and 2. Awareness that swelling of the dorsum of the hand or foot can be the sole sign and symptom of Maffucci syndrome before the typical indications become evident helps the physician establish an early diagnosis of this condition.

Case ReportsDislocation of the proximal tibiofibular joint.A new method for fixation.
We introduce a new method for fixation of a rare, isolated, proximal tibiofibular dislocation. One third of the biceps femoris muscle tendon was used for fixation of the dislocated proximal fibular head. The fixation was achieved by using a soft threaded interference ACL screw.

Case ReportsOsteonecrosis of the femoral head associated with pregnancy.
A 31-year-old pregnant woman suddenly complained of bilateral hip pain 2 weeks before delivery. She was delivered of triplets by Caesarean section. She had been treated with human menopausal gonadotropin and human chorionic gonadotropin (hMG-hCG) before pregnancy. ⋯ She had no history of steroid therapy or alcohol abuse. Osteonecrosis of the femoral heads bilaterally associated with pregnancy was confirmed. Pathology of the femoral head showed typical empty lacunae and necrosis of the trabecula.

Serum cholesterol is elevated in patients with Achilles tendon ruptures.
Forty-one patients were analyzed after surgical treatment of Achilles tendon ruptures. The following parameters served as the outcome measure: (1) duration of wearing cast, (2) length of hospital stay, (3) outpatient treatment, (4) time of absence from work, (5) complications, (6) re-rupture rate, (7) subjective evaluation by patients, (8) scar condition, (9) ability to stand on tiptoes, (10) Thompson test, (11) movement of talocrural joint, (12) circumference data of lower extremity, (13) radiographs, (14) power measurement of the ankle (in kg), (15) ultrasound examination, (16) blood cholesterol levels, (17) scoring by Trillat's score. ⋯ Given the good results, surgical treatment of Achilles tendon ruptures is recommended, but patients of status post-Achilles tendon rupture should be checked for high cholesterol levels. In the future, controlled, prospective trials need to prove a correlation between Achilles tendon rupture and a pathological blood lipid status.
