Technique for Retraction of the Fourth Compartment Tendons in Approach to the Wrist Joint.

Most procedures that require exposure of the wrist joint requires us to go through the third and fourth compartment. This is followed by dividing the septum between the 3rd and 4th compartments and retracting the EDC tendons ulnarwards. This can be done by various techniques. Using a form of self-retaining retractor is cumbersome and has to be repeatedly repositioned as the tendons keep slipping out. We describe a novel method to maintain this retraction throughout any wrist procedure.

Functional Outcome of Surgically Managed Perilunate Injuries.

BACKGROUND: Perilunate injuries are rare and quite often missed. We present our experience and outcomes, surgically managing these difficult injuries. METHODS: We analysed data from 14 patients who underwent open reduction and internal fixation of perilunate injuries. All patients underwent open reduction and fixation through the dorsal approach. Fractures were fixed with either K-wires or Headless compression screws. At regular intervals radiographs, range of motion, grip strength, modified Mayo score, Quick DASH score and Lyon wrist scores were collected. RESULTS: The average age of our patients was 29.2. Average time to surgical intervention was 11.3 days. The mean follow-up period was 42.3 months. modified Mayo wrist score, QuickDASH score and Lyon wrist scores were 77.86, 1.62 and 80.86, respectively. Wrist flexion/extension arc was 101.43. Wrist radial/ulnar deviation was 50.0. Mean grip strength was 69.93% of the opposite side. Radiological evidence of wrist arthritis and lunate avascular necrosis was seen in 8 (57.14%) and 4 (28.6%) cases, respectively. CONCLUSION: Early open reduction of perilunate injuries gives reliable results, in spite of radiological evidence of wrist arthritis in a majority of the cases.

Anatomical study of anterior supramalleolar artery and its potential application to design a bi-foliate fasciocutaneous flap.

PURPOSE: A further understanding of the anterior supramalleolar artery (ASMA) and its potential applications in reconstructive surgery. MATERIALS AND METHODS: A total of 24 fresh lower limbs from fresh cadavers were injected with red latex for dissection. The type of origin, course, diameter of the pedicle, and the distance between the origin of the ASMA from the anterior tibial artery to the extensor retinaculum (O-R) were recorded. Bi-foliate fasciocutaneous flaps were harvested using the branches of the ASMA. RESULTS: We found four types of origin of the ASMA, and we have accordingly classified them into four types. 10 of them were type A, 7 were type B, 6 were type C and 1 was type D. The mean O-R (origin of ASMA to retinaculum) distance was 2.0 ± 0.8 cm. The diameter of the medial branch (D1), the diameter of the lateral branch (D2), and the diameter of artery stem (D3) (only in type A) were 1.0 ± 0.2 mm, 0.8 ± 0.3 mm, 1.1 ± 0.2 mm, respectively. The mean pedicle length of the lateral flap (L1) and medial flap (L2) were 5.1 ± 1.0 cm and 3.7 ± 0.6 cm, respectively. CONCLUSIONS: The ASMA exists constantly with four different types of origin. Its sizable diameter and lengthy pedicle make it suitable for bi-foliate fasciocutaneous flap transfer.

Pedicled vascularised fibular grafting in a flow-through manner for reconstruction of infected non-union of the tibia with preservation of the peroneal artery: a case report.

We report on an 82-year-old man with an infected non-union of the right tibia in which the peroneal artery was the sole artery supplying the lower leg, owing to peripheral arterial disease. He underwent tibial reconstruction using the pedicled vascularised fibular graft in a flow-through manner (without ligation of either the proximal or distal ends of the peroneal artery) and achieved successful bony union.

Reconstruction of shoulder and elbow function using multiple muscle transfers for cervical spondylotic amyotrophy.

STUDY DESIGN: This was a retrospective study of 8 patients with cervical spondylotic amyotrophy who underwent multiple muscle transfers. OBJECTIVE: The purpose of this study was to evaluate results of multiple muscle transfers about the shoulder and elbow in patients with cervical spondylotic amyotrophy. SUMMARY OF BACKGROUND DATA: Cervical spondylotic amyotrophy is characterized by severe muscle atrophy of the shoulder girdle and elbow. Even after cervical spine surgery, many patients have poor shoulder and elbow function. METHODS: Multiple muscle transfer procedures including the transfer of trapezius, pectoralis major, latissimus dorsi muscles, and the Steindler procedure for reconstruction of shoulder and elbow function were performed in 8 patients with cervical spondylotic amyotrophy. Patients were evaluated at a mean of 18.2 months (range, 5-75 mo). RESULTS: All 8 patients obtained satisfactory functional recovery with improvement of active range of motion without any systemic and local complications within 3 to 6 months postoperatively. Patients at the last follow-up had obtained a mean of 91° of shoulder abduction, 111° of shoulder flexion, 23° of external rotation and 110° of elbow flexion. Disability scores (Japanese version) of the arm, shoulder, and hand improved by a mean of 28 points. CONCLUSION: Multiple muscle transfers can improve shoulder and elbow function in cervical spondylotic amyotrophy, in cases of not only poor outcome after cervical surgery, but also in advanced paralysis. It is a useful set of procedures even in old patients, and provides definitive functional improvement of shoulder and elbow function from 3 to 6 months. LEVEL OF EVIDENCE: 4.

Intraosseous xanthoma of the distal radius - a case report.

An intraosseous xanthoma is a very rare condition. It has an aggressive appearance on radiographs mimicking primary or metastatic malignant bone tumors. We report a case of intraosseous xanthoma of the distal radius in a 51-year-old male with no history of hyperlipidaemia. To the best of our knowledge, this condition has not been reported so far in the wrist and forearm region. The lesion was successfully excised and at last follow-up, there were no signs of recurrence and patient has been symptom-free.
