OBJECTIVETo explore the blood supply of the reverse arterial arch at the superior border of the hallucal abductor island flap and provide an anatomical basis for repairing fore foot skin defect using this flap.

METHODSThe constitution, course, distribution, and external diameter of the arterial arch at the superior border of the hallucal abductor, and the concomitant veins and nerves were observed on 12 sides of formaldehyde-fixed and 12 fresh adult foot specimens perfused with red latex. The surgical approach using the arterial arch at the superior border of the hallucal abductor for repairing fore foot skin defect were designed.

RESULTSThe arterial arch at the superior border of the hallucal abductor, constituted by the branch of the medial tarsal artery or the branch of the anterior medial malleolus artery anastomosed with the superficial branch of the medial basal hallucal artery or the branch of the superficial branch of the medial plantar artery or the all the four branches, functioned as the axis of the medial tarsal, the medialis pedis and the medial plantar. The external diameters of the anterior medial malleolus artery, the medial tarsal artery, the branch of the superficial branch of the medial plantar artery, and the distal arterial arch at the superior border of the hallucal abductor were 1.02∓0.03 mm, 0.73∓0.04 mm, 0.56∓0.02 mm, and 0.53∓0.14 mm, respectively. Most of the arteries (91.67%) had one concomitant vein with the external diameters of 1.01∓0.03 mm, 0.81∓0.04 mm, 0.57∓0.01 mm, and 0.61∓0.02, respectively, and only a small fraction of them (8.33%) had two concomitant veins.

CONCLUSIONSThe fore foot skin defect can be repaired using this flap supplied by the branch of the anterior medial malleolus artery and the medial tarsal artery, the superficial branch of the medial plantar artery, or all the three. The pivot point formed by the neck of the first metatarsal or metatarsophalangeal joint allows for long vessel pedicles and larger flap areas to increase the flexibility of surgery.

The surgical treatment of massive rotator cuff tears is a clinical challenge for orthopaedic surgeons. Moreover, tendon retraction, adhesions and fatty infiltration after rotator cuff tear will further increase the difficulty of surgical repair. Therefore, it has become a hotspot and difficulty to repair massive rotator cuff tears with a better way in current research. In recent years, with the continuous development of arthroscopic techniques, shoulder arthroscopic surgery has become the gold standard for the treatment of massive rotator cuff tears, but the adaptations, effects and combined application of different surgical methods are still controversial. The author believes that arthroscopic debridement of shoulder joint and acromioplasty or tuberoplasty could relieve shoulder pain in the short-term for elderly patients with lower functional requirements;long biceps tenotomy or tenodesis is effective for patients with biceps long head tendon injury; complete repair is still the first line treatment for massive rotator cuff tears, but partial repair is possible for massive rotator cuff tears that could not be completely repaired;patch augmentation technology could bring good results for young patients with high functional requirements;for patients with limited internal and external rotation of the shoulder joint and high functional requirements, tendon transfers surgery is recommended;superior capsular reconstruction is more advantageous for young patients with no obvious glenohumeral arthritis, better deltoid muscle strength and higher functional requirements. In addition, subacromial spacer implantation has become a current research hotspot due to its advantages of small trauma, low cost and relative safety, and its long-term effect still needs to be further confirmed.

OBJECTIVETo summarize the clinical application results of the repair soft tissue defect in contralateral leg with a cross-leg soleus muscle flap pedicle transplantation.

METHODSFrom January 2008 to January 2013, 8 patients with soft-tissue defect in lower leg underwent reconstruction with a cross-leg soleus muscle flap pedicle transplantation (without microvascular anastomoses). There were 7 males and 1 female, aged from 20 to 49 years old with an average of 31.8 years. The operative time after injury was from 2 to 8 weeks with the mean of 46 days. The soleus muscle flap was transposed across to the contralateral leg defect area, then immediate to perform the coverage of the muscle flaps by a meshed split-thickness skin graft. The donor site was closed directly.

RESULTSAll the muscle flaps had survived completely. In one case, recipient area edge had a less exudate from drainage hole everyday, the incision spontaneously was healed after 2 week's changing dressing. Follow-up period ranged form 1.5 to 4 years with an average of 2.5 years postoperatively. The tibia and fibula fractures were healed well. A good contour was achieved at the recipient area. According to LEM standard, 2 cases got excellent results, 5 good and 1 fair.

CONCLUSIONSoleus flap pedicle transplantation is very suitable to repair the soft tissue defect of the injuried leg only one main blood vessel, and can reduce the damage of donor area.

BACKGROUNDTo repair late median nerve injury, many methods have been used in the past years. The aim of this study was to review a thirteen-year experience in restoration of thumb opposition by transposing flexor pollicis brevis muscle.

METHODSFrom July 1992 to August 2005, 63 patients without thumb opposition because of late median never injury were treated by transposing the flexor pollicis brevis muscle. All the patients had received primary nerve repair after the jnjury. The interval between the injury and the second operation was (1.87 +/- 2.31) years (6 months to 4.2 years). The patients were followed up for 3 to 48 [months mean (22.93 +/- 2.31) months]. A functional evaluation system designed in 1992 were used to estimate the outcomes of the patients.

RESULTSAll the patients gained excellent functional results without complications and disabilities during follow-up.

CONCLUSIONSRestoration of thumb opposition by transposing flexsor pollicis brevis muscle has the following advantages: 1. Operative trauma is minimal; 2. It is not necessary to transpose other tendons; 3. Except for the thumb in opposition, movements of other fingers and the wrist are not restricted postoperatively.

The purpose of this study was to evaluate a new extracapsular surgical technique for the treatment of cranial cruciate ligament rupture in small breed dogs. Nine small breed dogs (seven females and two males) weighing < or = 15 kg were treated with biceps femoris muscle transposition (BFT). The duration of the BFT procedure was 20 min. Each patient underwent a standard clinical protocol and a questionnaire for the owners. Follow-up (at 1, 3, and 12 months postoperative) confirmed significant improvement in all patients, especially at 1 month postoperatively (p < 0.01) and again after complete stifle joint assessment at 3 months postoperatively. After 12 months, only two patients showed a slight increase in osteoarthritis. According to our results, BFT is a simple extracapsular surgical technique that can be used for the treatment of cranial cruciate ligament rupture in small breed dogs.

This case demonstrates a rare variation in the pattern of injury and the presentation of acute lateral compartment syndrome of the leg. Although uncommon, lateral compartment syndrome of the leg after an ankle inversion leading to peroneus longus muscle rupture has been previously documented. This case was unusual because there was no overt ankle injury and the patient was able to continue physical activity, in spite of a significant rupture of the peroneus longus muscle that was determined later. This case highlights the necessary vigilance clinicians must maintain when assessing non-contact injuries in patients with possible compartment syndrome.

OBJECTIVETo explore the clinical effects of pedicled muscular flaps of brachioradialis in repairing wounds at proximal forearm resulted from hot crush injury.

METHODSFrom February 2003 to December 2008, 5 wounds at proximal forearm resulted from hot crush injury were repaired with pedicled muscular flaps of brachioradialis. The size of muscular flaps ranged from 6 cm x 4 cm - 9 cm x 5 cm. The wounds at donor sites were closed directly or by free skin grafts.

RESULTSAll the muscular flaps of brachioradialis were survived completely. 4 patients were followed up for 3 to 36 months. The cosmetic and functional results were satisfactory both in recipient areas and in donor sites.

CONCLUSIONSPedicled muscular flap of brachioradialis can not only repair wounds at proximal forearm resulted from hot crush injury, but also repair extensor muscle defects. It is an ideal method and is very practical.

OBJECTIVETo explore the methods and effects of repair of occipital and nuchal wounds with inferior trapezius myocutaneous flap after deep electrical bum.

METHODSTwelve patients with high-voltage electrical burn in occipital and nuchal regions were hospitalized to our ward from March 2003 to September 2007. They were repaired with improved inferior trapezius myocutaneous flaps after debridement. Flaps were of two types: (1) blood supply from cutaneous and perforator branches of the original segment of the superficial descending branch of transverse cervical artery. (2) combined blood supply from both superficial and deep descending branches of transverse cervical artery C, i.e., dorsal scapular artery). All flaps carried segmental and limited trapezius muscle cuff surrounding the vascular pedicle of the flap similar to a perforator flap.

RESULTSFlaps survived completely primarily in eight cases. In two patients, infection developed in flaps adjacent to wounds with lignification; they healed after dress change. Necrosis appeared in distal end of flap (one case), it healed after re-operation. One patient with surviving flaps died of sepsis and multiple organ failure 21 days after operation. The flaps which survived were not swollen ; the donor sites at scapular region looked normal without pterygoid or pendulous scapula deformities.

CONCLUSIONInferior trapezius myocutaneous flaps can be used to repair occipital and nuchal wounds, with the advantages of constant blood vessels, reliable blood supply, convenience for application.

OBJECTIVETo investigate the effects of free and pedicled thoracodorsal artery perforator (TDAP) flaps for repairing skin and soft tissue defects in limbs, neck, axillary and shoulder.

METHODSFrom October 2009 to Auguest 2011, 16 TDAP flaps were used to repair skin and tissue defects. Among them, five ipsilateral pedicled flaps were used to repair wounds in neck, axillary and shoulder. 11 free TDAP flaps were used to repair the wounds with bone or tendon exposure. In 12 cases, the flaps were pedicled with thoracodorsal artery and vein-lateral branches-perforators, in 4 cases, pedicled with thoracodorsal artery and vein-serratus anterior muscular branches-perforators. The deep fascia, the latissimus dorsi and thoracodorsal nerve were not included in all flaps. The flaps size ranged from 10 cm x 5 cm to 26 cm x 10 cm.

RESULTSAll 16 flaps survived completely with primary healing both at donor site and recipent area. After a follow-up of 3 to 24 months, all flaps gained good texture and appearance. Only linear scar was left at donor area. The shoulder could move freely.

CONCLUSIONSTDAP flap has good texture, long vascular pedicle,and reliable blood supply, leaving less morbidity at donor site. The latissimus dorsi and thoracodorsal nerve are also preserved. The pedicled TDAP flap is an ideal flap for repairing the ipsilateral skin and soft tissue defects of the neck, shoulder, axillary. The free TDAP flap is suited for repairing skin and soft tissue defects of the extremities.
