1/798. achilles tendon repair using a bone-tendon graft harvested from the knee extensor system: three cases. The authors describe a new surgical technique of achilles tendon reconstruction using bone-tendon graft from the knee extensor system. This technique is for those unusual cases of neglected or partial achilles tendon rupture with distal tendon-substance loss at calcaneal insertion level, requiring transbone plasty fixation. Three cases are reported; the first two, followed up over a 5-year period, had excellent functional, morphological, and clinical outcomes. This new technique is compared with other available solutions: triceps plasty, other local tendon plasty, artificial plasty, and allograft. ( info) |
| Triceps tendon rupture is a rare injury. Three cases are presented with a brief review of the literature. Additionally, the use of magnetic resonance imaging to facilitate the diagnosis of triceps tendon rupture is described for the first time in the English literature. Each of the three patients has done well with a Mersilene tape repair of the triceps tendon. ( info) |
| In contrast to routine flexor tendon injuries, flexor tendon ruptures following blunt injury or re-ruptures following repair can be difficult to diagnose. The authors investigated the efficacy of using ultrasound to assist in the diagnosis. From 1996 to 1997, 8 patients underwent evaluation of the flexor tendons using an ATL HDI-3000 ultrasound machine with a high-resolution, 5 to 9-MHz hockey stick linear probe. Dynamic evaluation was performed in real time, simulating clinical symptoms. Six patients underwent surgical exploration. Sonographic diagnosis and intraoperative findings were correlated. Ultrasound was used to diagnose 3 patients with ruptured flexor digitorum profundus tendons. Mechanisms of injury included forceful extension, penetrating injury, and delayed rupture 3 weeks after tendon repair. Subsequent surgical exploration confirmed the ruptures and location of the stumps. Five patients had intact flexor tendons by ultrasound after forceful extension, penetrating injury, phalangeal fracture, crush injury, and unknown etiology. In 3 patients who underwent surgery for tenolysis, scar release, or arthrodesis, the flexor tendons were found to be intact, as predicted by ultrasound. The authors found ultrasound to be accurate in diagnosing the integrity of flexor tendons and in localizing the ruptured ends. They conclude that ultrasound is helpful in evaluating equivocal flexor tendon injuries. ( info) |
4/798. Volar dislocation of the proximal interphalangeal joint of the finger: an indication for urgent operative treatment. Two patients are described with persistent acute volar dislocation of the middle phalanx of a finger. Closed reduction was impossible due to intra-articular interposition of the lateral slip of the extensor mechanism, combined with a tear of a collateral ligament. It is important to recognize these injuries at an early stage and an operative treatment is required. ( info) |
5/798. Arthroscopic treatment of infrapatellar tendonitis. Infrapatellar tendonitis is a chronic overload lesion in the patellar ligament at the attachment to the lower pole of the patella. This lesion is found primarily in athletes who participate in jumping sports. magnetic resonance imaging or ultrasound can show the extent of tendon pathology. Patellar tendonitis is treated with modification of activities, medications, and therapy. When conservative measures fail, operative debridement has been recommended. Previous reports have described a technique of open debridement of the patellar tendon, followed by an extended period of rehabilitation before returning to sports. Two athletes with persistent infrapatellar tendonitis were treated with an arthroscopic debridement. Both athletes returned to full activities without restrictions within 8 weeks of surgery. Arthroscopic treatment of infrapatellar tendonitis has not been previously described. This technical note describes the technique and two case reports of the arthroscopic treatment of infrapatellar tendonitis. ( info) |
| Three cases of complete amputation of the thumb are reported in which the amputated distal parts were not suitable for replantation. In all cases there were either complete or incomplete amputations of other digits. Two different techniques were used for thumb reconstruction: 1) pollicization of a partially amputated digit with transposition microsurgery in case 1; and 2) replantation of a less important amputated digit to the thumb stump for cases 2 and 3. These microsurgical efforts successfully restored thumb function in all three patients. ( info) |
7/798. Attritional flexor tendon ruptures due to distal radius fracture and associated with volar displacement of the distal ulna: a case report. Flexor tendon rupture following distal radius fractures are rare. In this report, a volarly displaced distal ulna that perforated the volar wrist capsule caused delayed flexor tendon ruptures 25 years after a distal radius fracture. The repair with free tendon graft and the excision of the distal ulna produced a successful result. ( info) |
8/798. Extensor tendon lacerations in a preterm neonate. A fetus of 30-weeks' gestation sustained 2 extensor tendon lacerations as an intraoperative complication of an emergency cesarean section. This report describes treatment of the tendon lacerations in the preterm neonate using 2 different repair techniques which both yielded an excellent clinical outcome. ( info) |
9/798. Extensor tendon dislocation in cerebral palsy. An 18-year-old man with cerebral palsy presented with a flexion deformity of the middle finger particularly at the metacarpophalangeal joint and ulnar dislocation of the extensor tendon. Releasing the tight ulnar sagittal band and imbricating the attenuated radial sagittal band allowed centralization of the extensor tendon. For complete correction of other deformities intrinsic release and extrinsic flexor muscle lengthening were done. Extensor tendon instability in this case was due to the combined forces of the extrinsic and intrinsic muscles on the retinacular system of the extensor mechanism. ( info) |
10/798. Neglected rupture of the patellar tendon. Neglected rupture of the patellar tendon is a rare but well recognised complication of knee trauma. We present the case of a 43-year-old man who sustained a complete rupture of the patellar tendon of his left knee following a fall. Clinical diagnosis was delayed by 2 months and was confirmed by magnetic resonance imaging. Treatment began with skeletal patellar traction and was followed by late reconstruction of the patellar tendon and transfer of the gracilis and semitendonosus tendons supplemented by figure-of-eight tension band wiring.
