RESUMEN
INTRODUCTION: Ulnar wrist pain is a frequent symptom with many possible traumatic and non-traumatic causes. The complex anatomy and biomechanics of the wrist with the ulnocarpal complex including the triangular fibrocartilaginous complex (TFCC), the distal radio-ulnar joint (DRUJ) and the ulnar carpal bones make the differentiation between the possible causes difficult. A precise clinical investigation and appropriate imaging studies are essential for detecting the most important differential diagnoses, the first therapeutical steps and an early and appropriate referral to the hand surgeon.

BACKGROUND: Ruptures of the Extensor pollicis longus tendon are commonly treated by Extensor indicis transfer using Pulvertaft suture technique. Current literature does not yet give evidence for a preferable post-operative therapy protocol. A side-to-side suture technique is significantly stronger than the Pulvertaft repair technique and therefore allows an immediate active postoperative treatment. We present a new postoperative protocol, which is simple, fast and safe, and should make treatment easier for patients and therapists. PATIENTS AND METHODS: We treated 10 patients with a transfer of the extensor indicis tendon between 07/2016 and 08/2017 according to the new active protocol. Patients were seen for follow-up at 2, 4 and 8 weeks. Thumb range of motion, pinch and grip strength as well as subjective parameters like pain and general satisfaction were measured. RESULTS: All patients regained full function of their thumbs with retropulsion over the level of the palm at 4 weeks. Median pinch strength was 89 % and grip strength 74 % of the contralateral side at week 4. There was no secondary rupture of the reconstructed tendon over a one-year period. All patients were satisfied with the result of the operation and the protocol. CONCLUSION: Our new active postoperative protocol for extensor indicis transfer using a side-to-side suture has proven to be safe and less strenuous for patients and therapists and has been established as standard treatment in our clinic.

INTRODUCTION: There is growing evidence of the superior ability of muscular tissue to clear bacterial bone infection. Unfortunately, in the hand, there are almost no small local muscular flaps, and muscular transfers to the hand are mainly microsurgical free transfers. In this report, we present the results of the use of a chimeric posterior interosseous flap including part(s) of the forearm muscles to treat osteomyelitis and soft tissue defect of hand from a series of patients. PATIENTS AND METHODS: Four male patients with an average age of 32 years (range 20-46 years), were affected by acute osteomyelitis in hand. Previous fracture fixation with percutaneous K-wires was the cause of bone infection in three case. In one case, the osteomyelitis was a consequence of an open fracture. The bones affected were four metacarpals and one proximal phalanx, all with a minimal cortical defect (from the K-wire) obscuring a larger medullary infection, which required extensive bone and overlying soft tissue debridement, leaving a soft tissue defect to be reconstructed of size ranging from 2 x 4 cm to 5 x 7 cm. The soft tissue defects were due to concomitant superficial infection and consequent debridement. All patients were treated with bone debridement and a chimeric posterior interosseous flap, which included part of the extensor digiti minimi and/or extensor carpi ulnaris to fill the intramedullary canal of the bones. No fixation of bone was necessary. RESULTS: The skin paddle of the flaps ranged from 2 x 5 cm to 5 x 6 cm, replicating the defect area, plus a teardrop tail of skin circa 1.5 cm wide and as long as the pedicle of the flap. The muscular components of the flaps used to fill the intramedullary canals ranged from 1 x 1 x 1.5 cm to 1.5 x 1.5 x 4 cm. All flaps survived and osteomyelitis resolved in all cases without major complications. At the final follow-up at 16 months (range 12-26 months), assessment of the hands using TAM, Power Grip and Key Pinch Strength measurements and, where appropriate, Kapandji scores, demonstrated satisfactory hand function. CONCLUSION: The chimeric posterior interosseous flap including part of the muscles of the forearm may be a robust solution for augmenting the flap bulk and may be used in cases of severe osteomyelitis of the hand.
