Les auteurs rapportent une série de 90 patients, présentant une section tendineuse des fléchisseurs de la main, et suivis avec un recul moyen de 8 mois (min: 2 mois; max: 13 mois). La lésion était localisée dans 12% des cas en zone I, 46% des cas en zone II, 2% en zone III et 25% des cas en zone IV et V. Pour le pouce (13 patients), 10 cas en zone T2 et 3 cas en zone T3. La technique opératoire utilisée était les sutures tendineuses en cadre de Kessler modifié, associée à un surjet épitendineux. Nous avons obtenus 54% de très bons résultats, 34% de résultats moyens et 12% de mauvais résultats. Pour le pouce les résultats semble moins bons avec un taux de résultats médiocre de 48%. Certes les chiffres de cette série sont moins bons que ceux des autres séries publiées dans la littérature. Les facteurs influençant les résultats sont d'abord l'utilisation d'immobilisation postopératoire systématique ainsi que le mécanisme d'agression, et la localisation à la zone II et au pouce. Les complications mécaniques sont représentées par 7% de rupture, toutes au niveau de pouce, et 31% des adhérences tendineuses (soit 30 cas), dont 19 en zone II, l'infections (22%) et 4% des cas d'algodystrophies.

This study report the results in 28 patients affected by closed fractures of the neck of the fifth metacarpal bone (boxer's fracture), treated with percutaneous elastic intramedullary nailing using a single wire, to verify the effectiveness of this surgical treatment. We reviewed the results of 28 patients treated with A single Kirschner wire (K-wire) pre-bent in a lazy-S fashion with a mild bend at approximately 5 millimeters, The K-wire is inserted blunt end first in an antegrade manner and the fracture reduced as the wire is passed across the fracture site The wire is usually removed with pliers post-operatively at four weeks in the fracture clinic. The follow-up period averaged of 20,75 months. The parameters evaluated included angulation, rotational alignment, postoperative metacarpophalangeal (MCP) range of motion, and time to union. We opted for this treatment in all cases, regardless volar angulation of the metacarpal head, malrotation of the fifth finger and associated or/no with a severe swelling of the hand. All the patients were reviewed clinically and radiologically at an average of 20,75 months after surgery. At the final follow-up, no patient reported residual pain and All fractures proceeded to bony union but we have one fracture had to be revised for failed fixation and three superficial wound infections needed antibiotic treatment. We recommend that this minimally invasive: percutaneous intramedullary nailing using a single k-wire in all metacarpal neck fracture( boxers’ fractures), especially when severe swelling of the hand is present, with good functional results and low morbidity.

From the functional standpoint, the hand is one of the most important organs of the body. However, its significance depends largely upon the pincer action of the thumb-index. The management of traumatic lesions of the hand is nowadays’ subject of numerous scientific discussions. We present here the case of a patient with a recent laceration of the central slip of the extensor tendon with boutonniere deformity linked to a dislocated interphalangeal thumb of the same hand with a loss of force of the clip thumb and index finger. This combination is a rare lesional of the traumatic hand that has not been previously reported in any orthopedic literature. It was observed after adopting the orthopedic treatment that the range of motion of its joint was at the same level as its healthy side without observing any redislocations during the 6-month follow-up period.
