De Quervain's tenosynovitis: a non-randomized two-armed study comparing ultrasound-guided steroid injection with surgical release.

PURPOSE: Ultrasonography is currently used for both diagnostic and therapeutic purposes in de Quervain's tenosynovitis. There is a dearth of information on how effective an ultrasound-guided (USG) steroid injection is when compared to surgical release of the first extensor compartment. Hence, we performed a non-randomized two-armed comparison study to test our hypothesis that USG guided steroid injection is equally effective as surgery. METHOD: 62 consecutive patients participated in the study with 32 of them selecting the option of USG guided injection (Set A), and the rest undergoing surgical release (Set B). We reviewed them after 3 and 6 weeks and 6 months for functional outcome using DASH, PRWE and VAS scores, recurrence, or any complications. They were further followed if they were symptomatic. RESULTS: The DASH/PRWE/VAS scores improved at the end of 6 months from 81.7/79.3/6.8 to 1.0/1.7/1.0, respectively for patients undergoing USG guided steroid injection. Similarly, for the patient undergoing surgery, the scores improved from 82.2/81.5/6.7 to 1.7/3.4/1.0, respectively. This was statistically significant in both the groups (p < 0.05) and was comparable to each other. Two patients in Set A came back with recurrence at eight and 10 months and two reported occasional pain on heavy work. Three patients had tenderness and two had numbness in Set B at the scar site. CONCLUSION: We observed that USG guided steroid injections are comparable to surgical release in terms of pain relief, functional outcome, complications.

Functional and cosmetic outcome of single-digit ray amputation in hand.

PURPOSE: To assess patient satisfaction, functional and cosmetic outcomes of single-digit ray amputation in hand and identify factors that might affect the outcome. METHODS: Forty-five patients who underwent ray amputation were evaluated, 37 males and eight females whose mean age was 36.6 years ranging between 15 and 67 years. Twenty-eight patients had dominant hand involvement. Twenty-one patients underwent primary ray amputation, and 24 patients had secondary ray amputation. Eight out of the 23 patients with central digit injuries underwent transposition. Grip strength, pinch strength, tactile sensibility and functional evaluation using Result Assessment Scale (RAS) and DASH score were analysed. Cosmetic assessment was performed using visual analogue scale (VAS) for cosmesis. RESULTS: Median time of assessment after surgery was 20 months. Average loss of grip strength and pinch strength was found to be 43.3 and 33.6%, respectively. Average RAS score was 3.75. Median DASH score was 23.4. Eighty-three percentage of patients had excellent or good cosmesis on the VAS. Transposition causes significant increase in DASH scores for central digit ray amputations but was cosmetically superior. Middle finger ray amputation had the maximum loss of grip strength, and index finger ray amputation had greater loss of pinch strength. Affection of neighbouring digits caused greater grip and pinch loss, and a higher DASH score. Primary ray resection decreased the total disability and eliminated the costs of a second procedure. CONCLUSION: Following ray amputation, one can predict an approximate 43.3% loss of grip strength and 33.6% loss of pinch strength. The patients can be counselled regarding the expected time off from work, amount of disability and complications after a single-digit ray amputation. Majority of the patients can return to the same occupation after a period of dedicated hand therapy. LEVEL OF EVIDENCE: Therapeutic, Level III.

Recurrent Primary Synovial Sarcoma of Median Nerve: A Case Report and Literature Review.

We report a case of intraneural synovial sarcoma of the median nerve in a 39 year old lady with multiple local recurrences over thirteen years with no distant metastasis. The diagnosis of biphasic type of synovial sarcoma was confirmed by histopathology and immunohistochemistry. At the time of the fourth recurrence below elbow amputation was performed. This case is being reported for its rarity and propensity for local recurrence without distant metastasis.

Reconstruction of Attritional Rupture of Flexor Tendons with Fascia Lata Graft Following Distal Radius Fracture Malunion.

Incidence of multiple flexor tendon rupture following distal radius fractures is rare with very few cases being reported in literature. We present an unusual case of a patient who had come to us with complaints of weakness and paresthesia of the right hand of one month prior and with a past history of dorsal plating for distal radius fracture nine years ago. Radiographs showed a distal radius fracture malunion with intact dorsal plate and protrusion of screws through the volar cortex. On exploration, attritional ruptures of all digital flexors were found with sparing of the Flexor Pollicis Longus tendon. The fibrous mass was excised and flexors reconstructed with a fascia lata graft. Attempt was made to correct the malunion with radial and ulnar osteotomies. At one year the patient had excellent restoration of digital flexion.

Use of Amnion Transfer in Resistant Nonhealing Venous Leg Ulcers.

In the treatment of venous leg ulcers, after adopting many treatment modalities, at times we are still left with a local indolent problem, "the resistant nonhealing venous ulcer." With repeated surgical procedures failing to obtain a healed ulcer, constant pain, persistent discharging wound, infections, etc., many a patient turn hostile. Also, there comes a dimension of despair in the health feeling of the patient. This prospective study was conducted in 40 patients, who were within the inclusion criteria (January 2006-January 2010, 12 males and 28 females, mean age 45 years). A single amniotic membrane (AM) transfer was done after preparation of the wound, and the parameters were assessed periodically. Follow-up for a minimum period of 1 year in all cases and a maximum period of 3 years in many cases (38) was done. Significant clinical response was defined as an ulcer healing greater than 75 % of the original area. Treatment failure was taken as a persistence or recurrence of more than 25 % of the ulcer area in a 1-year follow-up period. The preliminary results of good ulcer healing and no recurrence are encouraging, even up to 3-year follow-up. This proof-of-concept study demonstrates that AM transfer is useful, safe, inexpensive, readily available, and well accepted by patients, with tremendous potential in promoting epithelial healing in "the resistant nonhealing chronic venous leg ulcer."

The reverse posterior interosseous artery flap: technical considerations in raising an easier and more reliable flap.

PURPOSE: Major injuries of the hand with skin loss often require early flap cover, which should be versatile, simple in technique, and safe. The reverse posterior interosseus flap satisfies all of these requirements. Over the years, refinements in the technique of harvesting this flap have evolved to prevent venous congestion and flap necrosis. This study presents adaptations to avoid such complications and raise a successful flap. METHODS: A total of 21 patients underwent this flap reconstruction between January 2008 and November 2010 for injuries around the wrist and hand. The average follow-up period was 6 months; 19 were male and 2 were female. The average age was 33 years (range, 9-70 y). In 17 patients, the flap reconstructions were done for posttraumatic injuries, in 2 after skin defects following tumor resection, and 1 each after defects resulting from release of first web contracture in multiple congenital contractures and burns. Average size of the flap was 51 cm(2) (range, 90- 30 cm(2)). The donor area was covered by a split skin graft. RESULTS: All flaps survived without major complications. Generally the flap matched the surrounding skin except for palmar defects. No patients reported donor skin graft color mismatch. CONCLUSIONS: The reverse posterior interosseous flap is a reliable and safe flap for soft tissue cover to the wrist, palm, dorsum of hand, first web space, and metacarpophalangeal joints. Thorough attention to the technical details, including performing a proximo-distal flap dissection with the deep fascia, avoiding dissection of the anastomotic arc between posterior and anterior interosseous artery, creating a broad pedicle with a cutaneous handle, and avoiding its tunneling for inset, will contribute to survival of the flap.

Interaction between the UCP2-866G/A, mtDNA 10398G/A and PGC1alpha p.Thr394Thr and p.Gly482Ser polymorphisms in type 2 diabetes susceptibility in North Indian population.

In the recent past, we have observed a possible role of 10398A and 16189C mtDNA and PGC1alpha p.Thr394Thr (rs2970847) and p.Gly482Ser (rs8192673) variant genotypes providing susceptibility/protection against type 2 diabetes mellitus (T2DM) in two North Indian population groups. These initial observations encouraged us to look at the candidate genes in combination with -866G/A (rs659366) polymorphism in uncoupling protein 2 (UCP2) in a single study of a relatively large sample size, constituted of both the cohorts, to unravel an interesting outcome of an additive interaction in-between the studied genes. In a total of 1,686 individuals (762 cases and 924 controls) belonging to Indo-European linguistic group from North India, a comparison of risk genotype combinations of: UCP2-866GG, mtDNA 10398A and PGC1alpha p.Thr394Thr or p.Gly482Ser against the protective genotypes: UCP2-866XA, mtDNA 10398G and PGC1alpha p.Thr394Thr (nominal P value = 1.75 x 10(-14), Odds ratio, OR = 5.29, 3.40-8.22 at 95% CI) or PGC1alpha p.Gly482Ser (nominal p value = 4.42 x 10(-24), OR = 8.59, 5.53-13.35 at 95% CI), showed a highly significant difference and increased ORs. In a complex disease, it is always encouraging to find an additive interaction of multiple small effects of the studied candidate gene variations.

Mechanical failure in intramedullary interlocking nails.

PURPOSE: To study clinical and mechanical factors that predispose to failure of interlocking nails. METHODS: Between October 1996 and December 2002, 286 femoral fractures, 211 tibial fractures, and 47 humeral fractures were repaired using variously designed interlocking nails. Fracture pattern, level and site, nail size and type, weight bearing after nailing, and union status were reviewed after a mean follow-up of 22 months. RESULTS: Nail failure occurred in 27 fracture repairs (17 femoral, 9 tibial, and one humeral; 13 from our institution and 14 referred from elsewhere). In 55% of failed repairs, the fracture was distal. A high rate of tibial nail failure was noted. CONCLUSION: Distal fractures and stress concentration at the distal screws predispose to interlocking nail failure and can be prevented by protected weight bearing combined with the use of longer and larger nails. Routine supplementary cancellous bone grafting is unnecessary during renailing surgery when adequate reaming and a larger nail are used.

Bilateral macrodactyly of the hands and feet with post-axial involvement - a case report.

Macrodactyly is a rare congenital anomaly characterized by large digits. The usual involvement of macrodactyly is on the pre-axial side of the limb. There has been only one case report to date with involvement of both hands and feet in a child with post-axial upper limb involvement. We report an adult male who has macrodactyly of both hands and feet with post-axial involvement of both hands and pre and post- axial involvement of both feet.
