Muscles of flexor compartment of forearm have a common origin from medial epicondyle of humerus. Additional bellies of flexor muscles are commonly reported but presence of supernumerary muscles is an infrequent phenomenon. The present study describes an unusual muscle mass in flexor compartment of forearm simulating pronator teres. During routine dissection the upper limb of a 50 years old male cadaver, a supernumerary muscle was found on left side of the upper limb in the flexor compartment. The origin of the muscle was 2cm wide and aponeurotic in nature and attached to an oblique line extending from the inferior surface of the medial epicondyle and the medial surface of the trochlea...

INTRODUCTION: Flexor tendon dislocation from the flexor tendon groove posterior of the medial malleolus has been previously described, and may be difficult to diagnose initially, but is amendable to surgical treatment with good outcomes. We present a unique case of unilateral dislocation of the posterior tibialis and flexor digitorum longus tendons with contralateral flexor digitorum longus subluxation that was treated surgically with a good outcome. CASE PRESENTATION: A 37-year-old active duty male sustained a dislocation and subluxation of the flexor tendons bilaterally after a forced dorsiflexion injury...

The plantar plate is a major structure that maintains metatarsophalangeal joint (MTPJ) stability and has only recently gained attention. Anatomic plantar plate repair can directly address the pathologic entity, rather than relying on indirect reduction of the MTPJ instability by osteotomy or tendon transfer techniques. The present report aimed to determine the effectiveness of plantar plate repair for the treatment of patients with lesser MTPJ instability. Different databases were searched using the guidelines in the Cochrane Handbook and recommendations from the Preferred Reporting Items for Systematic reviews and Meta-Analysis statement...

Giant-cell tumor of the tendon sheath (GCT-TS) is an uncommon occurrence for a foot and ankle surgeon. However, there is a need to recognize the symptoms of typical and atypical presentations of this pathology. These benign neoplasms are recognized clinically as a soft-tissue mass that is usually painless and palpable. The foot and ankle account for only 3% to 5% of all GCT-TS in the body, with most being located in the hand. Giant cell tumor in the tendon sheath occurring in the foot and ankle is usually encountered on the lateral ankle and dorsum of the foot, occupying the extensor tendons...

BACKGROUND: Harvesting of the flexor digitorum longus (FDL) or the flexor hallucis longus (FHL) is a procedure used when tendon transfer is needed. It is commonly used in tibialis posterior reconstruction and Achilles tendon reconstruction. Harvesting of these tendons is sometimes difficult and time-consuming. It is important to obtain sufficient length to make a loop around the navicular bone or anchor it in the calcaneus. We describe a technique in which a loop is passed from proximal identification of the FDL or FHL through the tendon sheath, harvesting it from a minimal plantar approach...

Ultrasound imaging of the musculoskeletal system is an important element of the diagnostic and therapeutic protocol. Clinical decisions, including those regarding surgical procedures, are often based solely on ultrasound imaging. However, detailed knowledge on the anatomy and a correct scanning technique are crucial for an accurate diagnosis. Modern ultrasonographic equipment allows obtaining detailed anatomical images of muscle tendons, ligaments, nerves and vessels of the carpal area. Ventral wrist ultrasound is one of the most common diagnostic procedures in patients with suspected carpal tunnel syndrome...

BACKGROUND: The most common cause of degeneration of the posterior tibial tendon is a congenital valgus deformity of the calcaneus. Other associated pathologies are forefoot supination, forefoot abduction and shortening of the gastrocnemius muscle. DIAGNOSTICS: Loaded x‑rays of the foot in three planes as well as the hindfoot alignment view enable evaluation of the axis of the foot under static loading conditions. The posterior tibial tendon can be imaged with ultrasound and magnetic resonance imaging (MRI)...

Mohammed M Al-Qattan
The classic donor motor units for opponensplasty are the flexor digitorum superficialis, the extensor indicis proprius, the palmaris longus, and the abductor digiti minimi. Occasionally, all classic donor motor units are not available for the opponensplasty; a review of the literature revealed that the flexor carpi ulnaris opponensplasty has not been previously described. The surgical technique of the split flexor carpi ulnaris opponensplasty is described in the current paper along with a clinical example...

PURPOSE: The availability of tendon grafts is an important consideration for successful upper extremity reconstructive surgery, including flexor or extensor tendon reconstructions, tendon transfers, and ligament reconstructions. Graft selection is based on availability, expendability, ease of harvest, and length. Given variations in patient height and extremity length, existing average values may provide suboptimal insight into actual tendon lengths available. The purpose of this study is, therefore, to pursue a method of estimating available donor tendon lengths based on easily measured anatomical surface landmarks...

Irreducible ankle fracture-dislocations are very rare entities. The present case report demonstrates an unusual finding of tibialis posterior and flexor digitorum longus tendons interposed in the tibiofibular joint impairing successful closed reduction of ankle fracture-dislocation. A 45-year-old patient presented with a bimalleolar pronation-external rotation ankle fracture-dislocation after a motorcycle accident. Attempts to perform closed reduction before surgery were unsuccessful. Subsequent urgent open reduction and internal fixation surgical management revealed interposition of the tibialis posterior and flexor digitorum longus tendons in the tibiofibular joint...

To identify the optimal body surface puncture locations and the depths of nerve entry points (NEPs) in the deep posterior compartment muscles of the leg, 60 lower limbs of thirty adult cadavers were dissected in prone position. A curved line on the skin surface joining the lateral to the medial epicondyles of the femur was taken as a horizontal reference line (H). Another curved line joining the lateral epicondyle of the femur to the lateral malleolus was designated the longitudinal reference line (L). Following dissection, the NEPs were labeled with barium sulfate and then subjected to spiral computed tomography scanning...

BACKGROUND: Regenerative Peripheral Nerve Interfaces (RPNIs) are neurotized muscle grafts intended to produce electromyographic signals suitable for motorized prosthesis control. Two RPNIs producing independent agonist/antagonist signals are required for each control axis; however, it is unknown whether signals from adjacent RPNIs are independent. The purpose of this work was to determine signaling characteristics from two adjacent RPNIs, the first neurotized by a foot dorsi-flexor nerve and the second neurotized by a foot plantar-flexor nerve in a rodent model...
