- This retrospective, long-term study evaluated the influence of two different treatment protocols, one including infant periosteoplasty, on facial growth and occlusion in patients with complete bilateral cleft lip and palate (BCLP). Thirty-five patients with records of 5-, 8- and I 6-19-year-olds were included. Sixteen of these received infant periosteoplasty (BCLP-pp) to the cleft alveolus in conjunction with lip repair and a one-stage closure of the palate. The remaining 19 patients with a two-stage closure of the palate did not have an infant periosteoplasty (BCLP-np). The bone formation induced by periosteoplasty in the BCLP-np group was insufficient and both groups had secondary bone grafting to the alveolar clefts before the eruption of the lateral incisor or the canine. Facial growth was evaluated with cephalometry at the recorded ages and dental arch relationships with the Huddart and Bodenham crossbite scores at the age of 16-19 years. Until 19 years a significant retrusion of the maxillary position (SNA) was observed in both groups. At 16-19 years of age there was no significant difference of maxillary protrusion (SNA), intermaxillary position (ANB), maxillary length (ss-pm) or vertical skeletal relationships (ML/NSL, MI/NL) between the two groups. However, a significant difference of the crossbite scores was found. The BCLP-pp group did not show more facial growth problems but more malocclusion and the insufficient bone formation of the alveolar clefts after infant periosteoplasty required a secondary bone grafting.

- Abstract A major drawback with myoelectric prostheses is that they do not provide the user with sensory feedback. Using a new principle for sensory feedback, we did a series of experiments involving 11 healthy subjects. The skin on the volar aspect of the forearm was used as the target area for sensory input. Experiments included discrimination of site of stimuli and pressure levels at a single stimulation point. A tactile display based on digital servomotors with one actuating element for each of the five fingers was used as a stimulator on the forearm. The results show that the participants were able to discriminate between three fingers with an accuracy of 97%, between five fingers with an accuracy of 82%, and between five levels with an accuracy of 79%. The tactile display may prove a helpful tool in providing amputees with sensory feedback from a prosthetic hand by transferring tactile stimuli from the prosthetic hand to the skin at forearm level.

- An injury to the axillary nerve from a shoulder trauma can easily be overlooked. Spontaneous functional recovery may occur, but occasionally reconstructive surgery is required. The time frame for nerve reconstruction procedures is from a neurobiological view crucial for a good functional outcome. This study presents a group of operatively and non-operatively treated young adults with axillary nerve injuries caused by motorcycle accidents, where the diagnosis was set late. Ten young men (median age at trauma 13 years, range 9-24) with an axillary nerve injury were diagnosed by examination of shoulder function and electromyography (EMG). The patients had either a nerve reconstruction procedure or were treated conservatively and their recovery was monitored. The axillary nerve was explored and reconstructed at a median of 8 months (range 1-22 months) after trauma in 8/10 patients. Two patients were treated non-operatively. In 4/8 cases, a reconstruction with sural nerve graft was performed and in 1/8 case only exploration of the nerve was made (minor neuroma). In 3/8 cases a radial nerve branch transfer to the axillary nerve was chosen as the procedure. The shoulder was mobilised after 3 weeks with physiotherapy and the patients were monitored regularly. Functional recovery was observed in 9/10 cases (median follow up 11 months, range 7-64) with EMG signs of reinnervation in seven patients. Axillary nerve function should not be overlooked in young patients with a minor shoulder trauma. Nerve reconstruction can successfully recreate function.

Carpal tunnel syndrome and treatment of recurrent symptoms.

- Abstract Carpal tunnel syndrome is the most common compression lesion of peripheral nerves with a prevalence of 4%. It is often treated by release of the flexor retinaculum, which may completely relieve the symptoms. Although such treatment is considered successful, there are probably many patients with persistent or recurrent symptoms. Recurrence implies that the patient's symptoms were initially relieved but recurred some time after the operation; this is a controversial field in which clear definitions, aetiology, diagnosis, and treatment seem uncertain. We describe recurrence of carpal tunnel syndrome and summarise possibilities for diagnosis and treatment of the condition.

Dendritic fibromyxolipoma adherent to the median nerve in the forearm

- We describe a 65-year-old woman with a tumour adherent to the median nerve in the left forearm that was found to be a dendritic fibromyxolipoma, a distinctive benign soft tissue lesion possibly related to a myxoid spindle cell lipoma; it is a solitary fibrous tumour that may be mistaken for a sarcoma. The tumour was successfully excised with no complications.

- Malmö and Uppsala have been regional centres for the treatment of cleft lip and palate since the beginning of the 1950s. We have about 80 new cases every year and most patients have conventional oronasal clefts, either cleft lip and palate or isolated cleft palate. During a 10-year period we have come across four patients who have had varying degrees of midface dysplasia combined with intracranial anomalies. One child died at an early age, but the other three children were given medical substitution of hypopituitarism and have had their clefts reconstructed.

- The operative treatment of mallet fractures of more than one third of the articular surface is controversial. The purpose of this study was to evaluate the complications and functional outcome of extension block pinning technique. Thirty-six consecutive patients with mallet fractures that involved more than one third of the joint surface were treated by extension block pinning a median of 3 days after injury (range 0-35, mean 7). Clinical outcome was graded according to Crawford's criteria. At a median follow-up of 16.5 months (range 2.5-52, mean 20) 23 patients had an excellent or good result, 11 patients had a fair, and 2 patients a poor, clinical outcome according to Crawford's criteria. None of the patients complained of pain. The median extension loss was 0 degrees (range 0-20, mean 4) and the median flexion was 70 degrees (range 30-95, mean 68). Eight patients had operative or direct postoperative complications including superficial infection (n = 6), loss of Kirschner wire (K-wire) fixation (n = 1), and K-wire mal position (n = 1). The extension block pinning technique is a minimally invasive method of treating mallet fractures with low morbidity and a good functional outcome.

- Abstract When not enough conventional autologous nerve grafts are available, alternatives are needed to bridge nerve defects. Our aim was to study regeneration of nerves in chemically-extracted acellular nerve grafts from frogs, mice, humans (fresh and stored sural nerve), pigs and rats when defects in rat sciatic nerves were bridged. Secondly, we compared two different extraction procedures (techniques described by Sondell et al. and Hudson et al.) with respect to how efficiently they supported axonal outgrowth, and remaining laminin and myelin basic protein (MBP), after extraction. Isografts (rat) and xenografts (mouse) were transplanted into defects in rat sciatic nerves. Acellular nerve allografts from rats, extracted by the Sondell et al's technique, had an appreciably longer axonal outgrowth based on immunohistochemical staining of neurofilaments, than acellular nerve xenografts except those from the pig. Among acellular xenografts there was considerably longer axonal outgrowth in the grafts from pigs compared with those from humans (fresh), but there were no other differences among the xenografts with respect to axonal outgrowth. Axonal outgrowth in acellular nerve xenografts from mice, extracted by the method described by Sondell et al. was longer than in those extracted by Hudson et al's method, while there was no difference in outgrowth between extracted nerve isografts from rats. Electrophoretic analysis of extracted acellular nerve grafts showed remaining laminin, but not MBP, after both extraction procedures. These preserved laminin and removed MBP in acellular nerve grafts. Such grafts can be used to reconstruct short defects in nerves irrespective of their origin. However, selecting and matching a suitable combination of graft and host species may improve axonal outgrowth.
