tendon strangulation

BACKGROUND: Rotator cuff tears are a significant cause of shoulder morbidity. Surgical techniques for repair have evolved to optimize the biologic and mechanical variables critical to tendon healing. Double-row repairs have demonstrated superior biomechanical advantages to a single-row. METHODS: The preferred technique for rotator cuff repair of the senior author was reviewed and described in a step by step fashion. The final construct is a knotless double row transosseous equivalent construct...

BACKGROUND: Extensive pulp defects of the thumb, with the exposure of tendon or bone, are challenging reconstructive problems. Surgical treatment includes the use of local, regional, and free flaps. AIM: This paper is focused in Foucher's neuro vascular flap. First DMCA or Foucher's pedicle flap is a successful thumb reconstruction method, especially in patients not disturbed by its cosmetic appearance. MATERIAL AND METHODS: The first dorsal metacarpal artery (FDMCA) arises from the radial artery in the first intermetacarpal space, just distal to the tendon of the extensor pollicis longus...

Hereditary neuropathy with liability to pressure palsies is an inherited disease associated with the loss of a copy of the PMP22 gene. The condition leads to mononeuropathy due to compression and easy strangulation during daily life activities, resulting in sudden muscle weakness and sensory disturbance, and displaying symptoms similar to cerebrovascular diseases. We report the case of an 80-year-old man with left paralysis due to chronic cerebral infarction. His medical history indicated remarkable recovery from about 4 months after the onset of left hemiplegia with predominant involvement of the fingers...

OBJECTIVES: To evaluate and compare the in vitro biomechanical results from two stitches: the Mason-Allen stitch, as modified by Habermeyer; and the locked double-tie stitch developed at our service, on tendons of the infraspinatus muscle of sheep. METHODS: Twenty tendons from the infraspinatus muscle of sheep were randomly divided into two groups: LDT, on which the locked double-tie stitch was performed; and MA, with the modified Mason-Allen stitch. The evaluation was performed in the mechanics laboratory, using a standard test machine with unidirectional traction, constant velocity of 20 mm per second and a 500 N load cell, without force cycling...

We present a suture bridge technique for reattachment of tendon or ligament to bone for use in foot and ankle surgery. The method is a simple, strong, and reproducible technique that could decrease the risk of irritation of the overlying cutaneous barrier and minimizes the likelihood of tendon strangulation when combined with soft tissue bone anchors. The present report serves as a guide to the use of this suture technique for reattachment of the Achilles tendon.

OBJECTIVE: To investigate the treatment outcome of applying venous Flow-through flap in the replantation of severed finger with circularity soft tissue defect and vascular defect. METHODS: Between January 2010 and December 2012, 11 cases (11 fingers) of severed finger with circularity soft tissue defect and vascular defect underwent replantation with venous Flow-through flaps. There were 8 males and 3 females, aged 18-42 years (mean, 24.6 years). The cause of injury was squeeze injury in 6 cases, crush injury in 3 cases, and strangulation in 2 cases...

Hair toe tourniquet syndrome (HTTS) is an uncommon pediatric condition occurring when the toe is circumferentially strangulated by human hair or fibers. An 8-week-old little girl was admitted to the Emergency Department because of the worsening swelling in the right second and third toes, which had been been previously treated with a local antibiotic thinking of an infection. An unrecognized HTTS was leading the third toe to necrosis. An urgent release of the constricting band on the two toes was performed and bone erosion and partial flexor tendon lesion on the third toe were detected...

PURPOSE: The goal of this study was to evaluate the clinical and radiological results of the arthroscopic knotless-anchor Speed-Bridge technique, in particular the pattern and the rate of retears. The results were compared with a modified Suture-Bridge knot-tying technique (mDR). The hypothesis is that arthroscopic knotless-anchor Speed-Bridge rotator cuff repair is a sufficient technique to address supraspinatus tears and differs in pattern of retears when compared to mDR. METHODS: This study includes twenty-two consecutive patients (8f/14m ø 63...

An incarcerated inguinal hernia is a common diagnosis, since the risk of an inguinal hernia incarcerating or strangulating is around 0.3-3%. An acute rupture of the adductor longus tendon is rarely seen and mostly affects (semi-) professional sportsmen. We present a case of a patient with an assumed incarcerated inguinal hernia which turned out to be a proximal adductor longus tendon rupture. If patients without a history of inguinal hernia present themselves with acute groin pain after suddenly exorotating the upper leg, a rupture of the adductor longus tendon should be considered...

Strangulation around cuff tissue is a possible cause of retear after rotator cuff repair. Therefore, tendon healing ideally requires changes in suture tension over the cuff tissue in accord with rotator cuff muscle activity. The authors present a type of fixation that mimics the mechanism of the Chinese finger trap. The devised knot-free tendon trap technique resembles the double-pulley-suture bridge technique, but all suture limbs share the tension evenly and respond synchronized to the cuff tendon. The technique provides simple biologic repairs of rotator cuff tears...

BACKGROUND: When using a method of suture bridge technique, there may be a possibility of strangulation of the rotator cuff tendon at the medial row. The style of knots chosen to secure the medial row might conceivably be a factor to reduce this possibility. PURPOSE: To compare the clinical results and repair integrity of arthroscopic rotator cuff repair between a knotless and a conventional knot-tying suture bridge technique for patients with full-thickness rotator cuff tears and to evaluate retear patterns in the cases with structural failure after arthroscopic repair by magnetic resonance imaging (MRI)...

We present a new method of suture bridge technique for medial row fixation using a modified Mason-Allen stitch instead of a horizontal mattress. Medial row configuration of the technique is composed of the simple stitch limb and the modified Mason-Allen stitch limb. The limbs are passed through the tendon by a shuttle relay. The simple stitch limb passes the cuff once and the modified Mason-Allen stitch limb passes three times which creates a rip stop that prevents tendon pull-out. In addition, the Mason-Allen suture bridge configuration is basically a knotless technique which has an advantage of reducing a possibility of strangulation of the rotator cuff tendon, impingement or irritation that may be caused by knot...

The double-row rotator cuff repair has proved to be biomechanically superior to the single-row technique. However, this has not been shown clinically. At the moment, all the methods proposed for medial-row suturing in the suture-bridge technique recommend a mattress suture or a simple stitch. The lasso-loop stitch has been proposed as a technique to improve tissue grip and has been used in open rotator cuff repairs, in biceps tenodesis, and in the Bankart procedure. We propose a method in which a modified version of this stitch can be used to repair the medial row of a double-row repair...

A 30-year-old male who had suffered from the left hemopneumothorax due to the traffic accident 13 years before was admitted to our hospital suffering from abdominal pain. Computed tomography revealed the stomach was incarcerated through the left central tendon of the left diaphragm. He was diagnosed as delayed traumatic diaphragmatic hernia and emergency operation was performed via thoracic approach. Stomach and omentum, densely adhered to the lung and the chest wall, were strangulated in the left pleural cavity and hardly reducible...

Surgical repair of the rotator cuff must have good resistance and should restore the tendon footprint. To attain this goal, a stitch with a strong biomechanical profile that avoids tissue strangulation should be used. We describe an arthroscopic suture technique undertaken to repair rotator cuff tears with a single triple-loaded suture anchor. The technique consists of a combination of a horizontal mattress and 2 vertical simple sutures that are positioned medial to the mattress suture. The suture anchor used is the 5-mm self-tapping ThRevo (Linvatec)...

This report presents a case of direct injury to the dorsal sensory branch of the ulnar nerve caused by arthroscopic repair of the triangular fibrocartilage complex. The dorsal sensory branch of the ulnar nerve was strangulated by one of the three pull-out sutures of the joint capsule, just ulnar to the extensor carpi ulnaris tendon. Pain and dysaesthesia of the ulnar side of the wrist was completely relieved after excision of the injured nerve segment. This complication can be avoided by careful exploration of the dorsal sensory branch of the ulnar nerve prior to suturing or passage of instruments during arthroscopy...

This is a retrospective review of 30 consecutive patients with acute Achilles tendon ruptures treated surgically by a single surgeon between 1992 and 1999. Repair was effected with a 26-gauge "pull-out" wire technique. A compressive dressing reinforced with plaster was employed to immobilize the ankle in neutral for 6 weeks. The hardware was removed 6 weeks postoperatively under local anesthesia. Intensive physical therapy was employed until ankle motion was symmetric and single heel raise was possible. Average follow-up was 4 years (range, 1-8 years)...

We present eight cases of the hair-thread tourniquet syndrome which affected the toes in 6 cases and presented strangulation of the penis in two. All patients were infants and the mechanism of injury was the strangulation by hair or thread wrapped around an appendage. Neither lesions were promptly recognized by their physicians and the patients were seen in the emergency room with swelling, erythema and a circumferential scar with the typical distal edema. The lesions had ischemic signs, but without tissue necrosis...

Circular scarring on extremities during replantation, pollicization, and "on-top"-plasty could strangulate nerves, vessels and tendons beneath the scar. Decompression could be achieved by single or multiple Z-plasty. During replantations we use the incisions for the Z-plasty to dissect the ends of the nerves and vessels for suturing. The scar created has a zig-zag form which with time becomes more flat but does not cause constriction of neuro-vascular bundles and tendons. The method is simple and does not take too much time...
