Assessment of long-term donor-site morbidity after harvesting the latissimus dorsi flap for neonatal myelomeningocele repair.

BACKGROUND AND AIM: The latissimus dorsi flap (LDF) has been employed very successfully over decades to cover large soft-tissue defects. Its donor-site morbidity has been extensively investigated in adults - but not in children - and is considered to be nonrestrictive. The aim of this long-term study was to assess donor-site morbidity with the modified Constant score more than 8 years after coverage of large myelomeningocele (MMC) defects with a reverse latissimus dorsi flap. METHODS: Within the first days after birth, the reverse latissimus dorsi muscle flap was used uni- or bilaterally in three neonates to cover a large MMC defect. Bilateral shoulder function was tested more than 8 years postoperatively according to the modified Constant score. RESULTS: The mean age at follow-up was 11.7 years. None of the patients experienced any pain or shoulder restrictions during normal daily activities. They all managed to position both of their arms comfortably above the head. Forward flexion was normal in all patients as was abduction and external rotation. Dorsal extension was minimally reduced on the operated side. Internal rotation was symmetric in all patients; the extent of active movement varied from excellent to poor. CONCLUSIONS: Our long-term data suggest that there is no specific and significant impairment of shoulder function after using the distally pedicled reverse LDF for neonatal MMC repair.

[Photography in Hand Surgery. Basic knowledge and standards]. / Fotografie in der Handchirurgie. Grundlegende Kenntnisse und Standards.

Photo documentation plays an important role in hand surgery. Pre- and postoperative documentation, planning of interventions, patient information as well as publications and presentations all require high quality images. Last but not least an accurate documentation is necessary for legal reasons. We present basic knowledge of equipment, photo and processing methods and illustrate imaging techniques and photographic standards for professional work flows in daily hand surgery.

[A case of nerve angiomatosis associated with neurofibromatosis type I]. / Ein Fall Neuroangiomatose bei Neurofibromatose Typ I.

We present the case of a patient suffering from Neurofibromatosis type I (NF-1) with acute, very painful neuropathy of the right lower extremity. The preoperative electro neuro- physiological study showed an impaired function of the peroneal nerve. The MRI revealed an extended diffuse plexiform tumour of the sciatic nerve and at thigh level. Biopsies showed marked diffuse angiomatosis within the sciatic nerve.To our knowledge, this is the first description of an intraneural vascular malformation in NF-1.Treatment of such an entity is a challenge and must be individually defined.

Painful nodules and cords in Dupuytren disease.

PURPOSE: The etiology of Dupuytren disease is unclear. Pain is seldom described in the literature. Patients are more often disturbed by impaired extension of the fingers. We recently treated a series of patients who had had painful nodules for more than 1 year, and we therefore decided to investigate them for a possible anatomical correlate. METHODS: Biopsies were taken during surgery from patients with Dupuytren disease and stained to enable detection of neuronal tissue. RESULTS: We treated 17 fingers in 10 patients. Intraoperatively, 10 showed tiny nerve branches passing into or crossing the fibrous bands or nodules. Of 13 biopsies, 6 showed nerve fibers embedded in fibrous tissue, 3 showed perineural or intraneural fibrosis or both, and 3 showed true neuromas. Enlarged Pacinian corpuscles were isolated from 1 sample. All patients were pain free after surgery. CONCLUSIONS: Although Dupuytren disease is generally considered painless, we treated a series of early stage patients with painful disease. Intraoperative inspection and histological examination of tissue samples showed that nerve tissue was involved in all cases. The pain might have been due to local nerve compression by the fibromatosis or the Dupuytren disease itself. We, therefore, suggest that the indication for surgery in Dupuytren disease be extended to painful nodules for more than 1 year, even in the early stages of the disease in the absence of functional deficits, with assessment of tissue samples for histological changes in nerves.

What benefits does ultrasound-guided axillary block for brachial plexus anaesthesia offer over the conventional blind approach in hand surgery?

Axillary block for brachial plexus anaesthesia is a popular anaesthetic technique for hand surgery with different approaches. We investigated the efficacy of the blind and ultrasound-guided approaches administered by a hand surgeon. A total of 141 patients were prospectively randomized to Group A without and Group B with ultrasound guidance. The principal variables evaluated were number of failures, duration of surgery, time to onset of anaesthesia, volume of anaesthetic injected, and complications. The success rate and the mean time to onset of anaesthesia were significantly better under ultrasound guidance. The duration of surgery and the rate of complications did not differ. Ultrasound-guided plexus anaesthesia is markedly more effective than the blind technique when performed by a hand surgeon.

Intramedullary splinting or conservative treatment for displaced fractures of the little finger metacarpal neck? A prospective study.

Forty patients with a 30° to 70° palmar displacement of a little finger metacarpal neck fracture were treated either with closed reduction and intramedullary splinting, or conservatively without reduction. Functional mobilization was started after 1 week in both groups. A radiological and clinical assessment of flexion and extension of the small finger metacarpophalangeal joint was done at 2 and 6 weeks, and at 3, 6 and 12 months. In addition patient satisfaction and grip strength were recorded at 12 months. No statistically significant differences in range of motion and grip strength were found between the two groups. Patient satisfaction and the appearance were superior in the surgically treated group. We conclude that intramedullary splinting for displaced fractures of the little finger metacarpal neck offers an aesthetic, but not a functional advantage.

[Factitious disorder and self-mutilation in hand and plastic surgery]. / Artifizielle Störungen und selbstverletzendes Verhalten in der Hand- und Plastischen Chirurgie.

Self-mutilation in the context of factitious disorder can lead to prolonged and complicated treatment in every medical field. Because of a prevalence of 1-5% in hospitalised patients, it is important to be aware of this disorder to protect patients from self- and foreign-induced harm. Often the patient history gives important hints. The different manifestations of this disorder, the specific doctor-patient relationship, several techniques of confrontation and current treatment are presented. Clinical cases from the fields of hand and plastic surgery are presented.
