Avulsion injury of the flexor digitorum profundus tendon from distal phalanx is considered as a rare injury. Accrording to the classification by Leddy and Pacter, this case is Type III, which is a large bony fragment retained by the tendon. The distal pulley prevents retraction beyond the middle phalanx. We are reporting a case with brief review of literatures.

Open reduction and internal fixation using volar plating for the treatment of distal radial fractures (DRFs) is becoming an increasingly popular method. Tenosynovitis of extensor tendons causes delayed extensor pollicis longus (EPL) tendon rupture which known as complication following screw penetration of the dorsal cortex after volar plating for DRFs. As the reconstructive procedure for a closed ruptured EPL tendon in minimal displaced DRF, extensor indicis proprius (EIP) transfer is widely used. However, tendon injuries of the fourth compartment, which includes the extensor digitorum communis or EIP, can be caused by screw irritation after volar plating for DRFs. We encountered a rare case of failed EIP tendon transfer for delayed EPL tendon rupture after volar plating for a DRF. Because the EIP tendon can also be damaged by screw penetration, care must be taken to use EIP tendon for treatment of delayed EPL rupture after volar plating for DRFs.

Tendoachilles rupture has recently seen an increase in frequency, accounting for up to 40% of all tendon ruptures. However, an acute segmental rupture of the Achilles tendon is very rare with only one case caused by predisposing factors, such as steroid injection. In this report, we highlight an unusual clinical presentation of a segmental rupture of the Achilles tendon without any underling predisposing factor and without direct trauma. Herein, we discuss its mechanism. Twelve months after surgical repair with open technique, this patient became fully functional again in daily activity.

PURPOSE: Autologous platelet rich plasma (PRP) has been known to enhance tendon healing and improve tensile strength after tendon injury. This study investigated the dosage of PRP to increase the tensile strength. METHODS: PRP was harvested from peripheral bloods of the rabbits. Direct injury model was adopted using 60 achilles tendons in 30 rabbits. The autologous PRP was infiltrated into the Achilles tendon repair site of four groups (control, 0.1, 0.2, 0.4 mL) with different dosages. Tendons were harvested at 2, 4 and 8 weeks and subjected to measuring mechanical tensile strength and dosage of collagen content. RESULTS: At 2, 4, and 8 weeks, PRP administration following experimental achilles tendon repair resulted in an overall higher average tensile strength and collagen content compared to these of the control. Also, the lengthen the time, tensile strength and collagen content was increased. CONCLUSION: Autologous PRP enhanced tendon healing in rabbits. Within the PRP dosage setted by the author, more dosage of the infiltrated PRP increases the strength of the tendon and the dosage of collagen content. Further studies will be essential to determine the optimal dosage of PRP in clinical practice.

PURPOSE: To compare the clinical results of spontaneous rupture of extensor pollicis longus tendon treated by palmaris longus tendon graft (group I) versus extensor indicis proprius tendon transfer (group II). MATERIALS AND METHODS: Out of twenty-five patients who suffer from spontaneous extensor pollicis longus tendon rupture, twelve patients were treated by palmaris longus tendon graft and thirteen patients were treated by extensor indicis proprius tendon transfer. Postoperatively thumbs were immobilized with thumb spica splint for three weeks. Active and passive movement was allowed subsequently for six weeks. The functions of the thumbs were assessed by the Geldmacher criteria and statistically compared. RESULTS: The overall outcome was excellent in 5(20%) of patients and good in 17(68%) of patients and satisfactory in 3(12%) of patients. The mean scores using the Geldmacher criteria were 18.50 for palmaris longus tendon graft and 19.69 for extensor indicis proprius tendon transfer. No significant difference was noted between two groups. CONCLUSION: Both methods establish equally good clinical results in patient with chronic extensor pollicis longus tendon rupture. Extensor indicis proprius tendon transfer seems more available methods.
