[Conservative therapy for metatarsal 5 basis fractures - retrospective and prospective analysis]. / Konservatives Therapiekonzept bei Metatarsale-V-Basisfrakturen - Retrospektive und prospektive Analyse.

BACKGROUND: Approximately 30 % of all bone injuries are foot metatarsal fractures. Metatarsal V basis fractures occur most frequently. The classification is done into the tuberosity avulsion fractures, Jones fractures and stress fractures of the proximal diaphysis. The treatments of non-displaced fractures are generally conservative. The indication for surgical treatment depends on the load and the associated refracture rate. There are different types of treatment of these fractures. We present a possible approach to conservative treatments and show how different therapies affect healing of metatarsal V basis fractures and social reintegration of patients. METHODS: A retrospective study consisted of 68 patients analysed during a 9-year period, whereas for a prospective analysis 18 patients were included for a period of 3 years. The treatment was performed using either a splint, closed bandage of the ankle or special Göttinger Anklesplint bandage, with immediate pain-oriented full load in all groups. The subjective and objective treatment results were analysed accoding the Göttinger Phillips score. RESULTS: In retrospect, the fracture consolidation was observed after 8.1 weeks full load-bearing was achieved after 6.3 weeks on average. In the prospective analysis, the osseous consolidation occurred after 6.2 weeks, and the full load was applied after 1.7 weeks. After 10 weeks the treatment with the Anklesplint bandage was assessed with 105 points of a maximum 110 points of the Phillips score. The Anklesplint bandage was also the cheapest option in the cost comparison. CONCLUSION: Using the immobilisation of the metatarsal supination with the Anklesplint bandage the metatarsal V basis fractures can heal in a regular way. The functional outcome is better in comparison to the that with other treatments and it is a cost-effective treatment.

[Minimally invasive osteosynthesis. : even in talus fractures?]. / Minimal-invasive osteosynthese : auch bei talusfrakturen?

OBJECTIVE: Minimally invasive osteosynthesis of talar fractures. INDICATIONS: Minimally displaced fractures of the lateral process of the talus and talar neck fractures type 1 according to Hawkins classification. CONTRAINDICATIONS: Dislocated peripheral fractures. Displaced fractures of the talar neck or body. SURGICAL TECHNIQUE: For factures of the lateral process of the talus: short incision of skin over the lateral process of the talus. Gentle preparation and contact with the bone with scissors. Fragment reposition using a dentist's hook and Kirschner wire in a joy-stick technique under C-arm imaging. Stabilization with a miniscrew. For talar neck fracture Hawkins type 1: short incision of skin ventromedially and ventrolaterally. Blunt preparation of soft tissue and safe bone contact. Introduction of one small-fragment corticalis screw both medially and laterally under C-arm imaging. As an alternative, cannulated screws can also be used. POSTOPERATIVE MANAGEMENT: For fractures of the lateral process of the talus: postoperative protection in an ankle splint (air cast, gel cast) for 4 weeks. During this time moderate weight bearing is possible. For talar neck fractures Hawkins type 1: physiotherapy and only floor contact for 6 weeks. RESULTS: From January 1996 to December 2002, 44 talar fractures were operatively treated in our department. Six patients had talar neck fractures type 1 according the Hawkins classification and 3 patients showed fractures of the lateral process of the talus. From those injuries, 3 Hawkins type 1 fractures and 2 fractures of the lateral process were stabilized using minimally invasive osteosynthesis. The clinical outcomes were assessed using the Ankle Hindfoot Scale of the American Orthopedic Foot and Ankle Society. Both groups reached good cosmetic and functional results. We did not observe any avascular talar necrosis or nonunions in the two groups.

[Sudden blindness following operative care of a multiply traumatized patient: posterior ischemic optic neuropathy]. / Unerwartete Blindheit nach operativer Versorgung eines polytraumatisierten Patienten: Hintere ischämische N.-opticus-Schädigung.

A 32-year-old man had fallen from an 8-m high scaffolding and had suffered multiple traumatic injuries, such as compression fractures of the thoracic vertebrae (TV) 5-7 without incarceration of the spinal canal plus a distal femoral fracture. During surgery on the day of the accident, spondylodesis and dorsal stabilization of TV 4-7 using an internal fixator were carried out and the distal femoral fracture was stabilized with a dynamic condylar screw (DCS). On the day following the accident, the malposition of a pedicle screw located at the height of TV 4 and the borderline malposition of a pedicle screw of TV 7 were corrected. Between the day of the accident and day 8 after, the patient developed impaired vision and in the further course amaurosis associated with fixed pupils. No organopathy could be noticed which could have explained the sudden vision loss. A study of the literature was done, using the keywords "blindness" and "spine surgery." Only very few cases describing a connection of spine surgery and postoperative vision loss could be found. This article aims to elaborate on the few connections worked out in these investigations.

CUP (carcinoma of unknown primary) syndrome in head and neck: clinic, diagnostic, and therapy.

BACKGROUND: Up to 10% of all cervical lymph node metastases present without a known primary site. Between 70 and 80% of the found primary tumors are located in the head and neck region, because cervical lymph nodes represent the lymph drainage of the head and neck. PATIENTS AND METHODS: We demonstrate the clinic, diagnostic management and therapy of carcinoma of unknown primary (CUP) in this retrospective study of 75 patients who primarily presented cervical metastases with unknown primary tumor at the Otorhinolaryngological Department of the University of Leipzig, Germany. RESULTS: A primary tumor was found in 44% of the patients, and 76% of the primary tumors were localized in the head and neck region. The overall 5-year survival rate was 13.3%. The 34 patients with pretherapeutically detected primary tumors showed a tendency towards better survival, with a 5-year survival rate of 21% compared to 10% in patients with undetected primary. CONCLUSIONS: Following a thorough physical examination, radiologic imaging, i.e., computed tomography and/or magnetic resonance imaging, of the head and neck region as well a chest X ray, panendoscopy with biopsy of the most probable tumor sites, and diagnostic tonsillectomy should be performed. Further diagnostic procedures as gastroenterologic, urogenital and gynecological examinations should be performed, depending on histology and location of the node and under consideration of cost-benefit analysis. Curative treatment should at least include ipsilateral neck dissection and adjuvant irradiation of the complete cervical lymph drainage. In the literature, radiation of the laryngopharyngeal mucosa is still discussed controversially: some authors recommend the irradation of the pharyngeal mucosa extending from the nasopharynx to the upper esophagus, whereas others regard the resulting side effects as too high compared to the expected benefit.
