Aims

The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires.

Patients and Methods

This was a multicentre, parallel group, randomized controlled noninferiority trial conducted at 12 tertiary trauma centres in Germany. A total of 290 patients with acute displaced fractures of the fifth metacarpal neck were randomized to either intramedullary single-wire (n = 146) or dual-wire fixation (n = 144). The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire six months after surgery, with a third of the minimal clinically important difference (MCID) used as the noninferiority threshold. Secondary outcomes were pain, health-related quality of life (EuroQol five-dimensional questionnaire (EQ-5D)), radiological measures, functional deficits, and complications.

Aim: Because of the low prevalence, there is a poor evidence on the effective management of bone and joint infections of the carpus and metacarpus. We therefore studied the outcomes of patients undergoing surgical treatment at our department.

Method: We conducted a retrospective study on all patients operated on because of osteomyelitis of the carpus and metacarpus between January 1998 and June 2004. Main study endpoint were the infection controll rate at end of treatment and at time of follow-up.

Results: Of eleven subjects (nine men, two women) with a median age of 43 years (range, 19 to 79 years) serial débridement with temporary wound closure and surgical fixation proved successful in ten cases. We identified causative pathogens in ten cases (S. aureus: n=3, P. aeruginosa: n=3, mixed: n=4) by intraoperative biopsy. Eight subjects received local or free tissue flaps. A 73 year old man died in hospital.

Follow-up information was available for eight patients after a median of 19,5 months (range: 3 to 61 months). Seven of them did not show signs of recurrent infection.

Conclusion: Adhering to accepted standards of treating osteomyelitis, satisfactory control rates in carpal and metacarpal infection can be achieved while salvaging the hand.

From January 2000 to March 2004 16 thumbs after total avulsion-amputation were replanted in our hospitals. In 15 cases this was successful. In one case the thumb was lost 28 hours after replantation. Mostly the amputation was in the region of the first phalanx or the IP-joint of the thumb.

In all cases our operative procedure for this form of amputation was the reconstruction of the vessels with vein grafts after the osteosynthesis and the reconstruction of the tendons. The donorsite region for the grafts was in 12 cases the dorsal forefoot and in 4 cases the distal forearm. In none of these cases there was the possibility of reconstructing both arteries. Mostly only an anastomosis for one artery and one vein could be done. For none of these patients it was possible to reconstruct the nerves primarily. Until now transphers of neurovascular skinislands of longfingers, free nerve transplantations with coaptations to the proximal stump of the injured nerve, free nerve transplantations with coaptations to the trunk of the median nerve or in one case an end-to-side coaptation have been performed to achieve a resensibility of the thumbs. In one case a patient rejected an operative nervereconstruction, because a sprouting of the proximal stump of the injured nerve lead to a (reduced) sensibility of the thumb. In 4 cases a therapy to achieve a resensibility has so far not been carried out.

After replantations of injured thumbs necroses of the skin in different kinds were noticed. In 4 cases secondary skinreconstructions were necessary. All 15 successful replanted thumbs achieved very good results concerning function, strength and patient’s satisfaction.

Our results don’t agree with the mostly bad results after total avulsionamputations mentioned in literature. We think that the replantation after total avulsionamputation of the thumb has a high chance of being successful and can achieve very good longtime results.
