[Injury of the scapholunate interosseal ligament--scapholunate dissociation].

Scapholunate interosseal ligament tears manifested with pain, a popping, weakness of the wrist, or limited wrist motion, are probably the most frequent cause of carpal instability. Insufficiency of the injured scapholunate ligament results in pathologic scaphoid and lunate position with wrist kinematics changes that cause irreversible degenerative arthrotic changes. The timely diagnosis combined with proper treatment is required for successful therapy and carpal collapse prevention.

[Surgical treatment method of calcaneal intraarticular fractures].

Open repositioning and internal fixation of intraarticular calcaneal fractures has become a standard surgical method, however, concerns over its feared complications, including, in particular, secondary wound healing followed by osteomyelitis, continue fo be discussed. The aim of this study is to inform the surgical public about the surgical method. From February 2004 to September 2005, 26 intraarticular calcaneal fractures in 22 patients were operated using open repositioning and internal cast fixation. In four cases, the fracture was bilateral. The patients were indicated for the procedure based on the Sanders CT classification. The procedure included extensive L-shaped lateral approach (Seattle), anaemization, minimization of soft tissue disruption, and was followed by spongioplasty. In isolated dislocated sustentacular fractures, osteosynthesis through a medial approach was completed, using screws. Post-operatively, the extremity was not fixated and early rehabilitation was initiated. In majority of the operated patients, the skin cover healed per primam. In 3 patients, the wound healed per secundam intentionem. Complete fracture healing was x-ray confirmed in all patients. No signs of the osteosynthetic material release or of pronounced signs of subtalar arthrosis or of a foot arch collapse were present. No deep defects or other serious postoperative complications were recorded. The follow-up period lasted for 6-22 months and goes on. The patients followed for over a year period have no symptoms, they fully wightbear the operated extremity and they have returned to their original professions. Open repositioning and internal stable cast fixation is recommended as a standard treatment method in these fractures.

[Partial denervation of the wrist by excision of the interosseous nerves from the dorsal approach].

PURPOSE OF THE STUDY: The aim of the study was to optimize, on the basis of an anatomical study, the technique of partial denervation of the wrist in terms of safety for preserving motor innervation of the quadrate pronator muscle, and to include this technique in the range of reconstruction operations for the treatment of degenerative carpal diseases. MATERIAL AND METHODS: The technique of partial denervation of the wrist, using excision of the sensitive branches of the dorsal and volar interosseous nerves, carried out by one-stage surgery from the dorsal approach is presented in a group of 28 patients. The partial denervation was always performed in addition to reconstructive surgery on the proximal carpals and the distal radioulnar joint. On the basis of an anatomical study involving 40 cadaverous upper extremities, the authors determined the location for resection of the sensitive branch of the volar interosseous nerve that is not associated with the risk of damaged motor innervation of the quadrate pronator muscle. RESULTS: A reliable identification of the motor branches of the volar interosseous nerve was achieved when an approximately 2-cm incision in the interosseous membrane was made 1 cm distal to the passing anterior branch of the interosseous artery that was clearly seen in the operating field. This corresponded to an incision in the skin, leading in the proximal direction at a length of about 7 cm, made 2 cm proximal to the distal radio-ulnar joint. DISCUSSION: The identification of motor branches is often difficult and therefore the authors recommend resection of the sensitive branch of the volar interosseous nerve to be performed in a safe zone that was determined by a large number of anatomical dissections. Partial denervation carried out according to the principles of a physiological procedure does not pose a burden for the patient and can markedly enhance the effect of reconstructive surgery. CONCLUSION: Partial denervation of the wrist performed from the dorsal approach is a simple procedure easy to combine with other reconstructive operations on the wrist.

[Heel pain].

Heel pain is quite frequent clinical symptom in our population. Successful therapy derives from the problem aetiology. The most frequent source of pain is the mechanical basis, both on dorsal and plantar side of calcaneum. Therapy includes a variety of procedures, from routine measures to surgical intervention.
