Semitendinosus Tendon Augmentation for a Large Defect after Achilles Tendon Rupture: Two Case Reports:

Acute Achilles tendon ruptures usually occur in people between the ages of 30 and 40 years who participate in sports-related activities. Operative repair has become the standard treatment for acute Achilles tendon rupture in this group of patients. In chronic cases or if the gap is larger than 5 cm in revision surgery, end-to-end repair of the torn Achilles tendon is difficult and V-Y advancement will likely be insufficient. Often surgeons perform transfer of the flexor hallucis longus (FHL) tendon or use an Achilles tendon allograft, but it is difficult to harvest the FHL tendon in the deep midfoot area, and there are disadvantages to using commercial allograft. For this injury, we perform a V-Y advancement and a semitendinosus tendon transfer. Using a semitendinosus tendon in the repair of the Achilles rupture has to our knowledge not been reported. We report two patients in whom this operative technique was used. The procedure was simple and we had excellent results.

Extra-Articular Ganglion Cysts around the Knee Joint

Purpose The purpose of this study was to report clinical results of open excision of extra-articular ganglion cysts around the knee joint combined with arthroscopic management of intra-articular pathologies if present. Materials and Methods Of the total 107 cases of cystic lesions around the knee, 23 cases of extra-articular ganglion cysts were reviewed between January 2006 and July 2011. There were 13 males and 10 females with a mean age of 48 years (range, 30 to 73 years). The mean follow-up duration was 40 months (range, 30 to 60 months). Preoperative magnetic resonance imaging (MRI) scan was done in all cases. Open surgical excision of the cyst was performed after arthroscopic management of intra-articular pathologies in all but 1 case. At the last follow-up, Lysholm and International Knee Documentation Committee (IKDC) scores were evaluated and MRI was conducted to detect recurrence. Results The mean Lysholm and IKDC scores showed significant improvement (p=0.005 and 0.013, respectively).The location of the cysts was anterior in 9, lateral in 7, medial in 6, and posterosuperior in 1. Intra-articular pathologies were found in 16/23 cases (69.6%). In 10/23 cases (43%), the cyst was connected to the knee joint. Three months postoperative MRI did not show any recurrence of ganglion cysts except for 1 case. Conclusions In the treatment of extra-articular ganglion cysts, MRI can be useful for detecting intra-articular lesions and connecting orifices, and arthroscopic management of intra-articular pathologies with open excision of the cyst should be considered as a viable treatment option.

A Baker's Cyst Causing Common Peroneal Nerve and Tibial Nerve Entrapment Neuropathy : A Case Report

Degenerative disc disease of the lumbar spine caused leg pain with associated calf weakness and atrophy. However, an unusual case of leg pain and calf atrophy due to neural compression is reported. We reported a rare case of a Bakers cyst causing common peroneal nerve and tibial nerve entrapment neuropathy. Initially, after arthroscopic menisectomy and cyst decompression, Bakers cyst was recurred and then open excision was done. Until 1 year after surgery, the cyst was not recurred, increased muscle bulk was noted and EMG showed improved findings. But she continued to complain of lower leg weakness and sole paresthesia owing to delayed diagnosis and cyst decompression.

Trans-Scaphoid Perilunate Dislocation with Fractured Carpal Bones in a Child - A Case Report -

Transcarpal fractures and dislocations in children are rarely reported in the orthopedics literature. This is a case report of a 10-year-old boy who sustained a trans-scaphoid perilunate dislocation with fractures across the carpal structure: these included injuries to the capitate and triquetrum bones. Treatment consists of a closed reduction for the dislocation and using the dorsal approach, an open reduction with internal fixation of the fractures. The injury healed well with a full return of good wrist function. This unusual pattern of injury is described so that it may be more readily appreciated in the future.
