Reconstruction of mutilating hand injuries by microsurgical free tissue transfers from the foot.

INTRODUCTION: The aim of this study is to present various hand reconstruction methods and provide technical notes regarding the treatment of mutilating hand injuries using free-tissue transfers from the foot and to investigate whether these transfers provide patients with a usable hand or not. PATIENTS AND METHODS: Ninety patients with mutilating hand injuries were included in the study. A total of 101 procedures were performed. Patients were contacted by phone to evaluate their working status and to record any complaints regarding their donor sites. The Quickdash questionnaire was conducted for the 53 patients who could be reached. Operative techniques, secondary procedures, finger survival, and physiotherapy data were noted retrospectively. RESULTS: In 36 patients, a trimmed great toe was transferred to the thumb. Second toe-to-thumb transfers were performed in 8 patients, and second toe-to-finger transfers were performed in 10 patients. In 13 patients, 2 toes from one side were transferred, and in 6 patients, 3 toes were transferred to the hand. Bilateral toe transfers were performed in 9 patients. Eight patients underwent joint transfers, of which 2 involved joint transfers from both feet. The overall finger survival rate for the transfer procedures was 95.04%. The average Quickdash score of the patients who could be reached (n = 53) was 27.49, with 62.3% of the patients being able to use their hands in their previous jobs, and 26.4% needing to change their jobs because of their hand injuries. 41.5% of the patients had no donor site complaints. 47.2% had mild complaints, and 11.3% had major donor site complaints. CONCLUSION: Multiple-toe transfer techniques along with flap coverage options should be considered, and delicate planning is mandatory to achieve at least a basic or acceptable hand. Three toes, including the great toe, can be transferred in a single operation by dissecting both the dorsal and plantar arterial systems. Crush injuries of the dorsal side of the hand may be reconstructed using combined transfers of bones, joints, extensor tendons, and skin. In our series, 88.7% of patients with mutilating hand injuries were able to return to work after we performed tissue transfers from the foot.

Deep palmar tumorous conditions of the hand.

PURPOSE: Deep palmar tumors of the hand are very rare, and reported cases are usually benign. The most important issue is frequent anatomical variations with challenging surgical exposure and excision of these lesions. Some case reports or a small series of patients have been reported in the literature. The aim of this study was to present our experience with the deep palmar tumors of the hand. PATIENTS AND METHODS: In the study, retrospective analyses of 43 patients treated with deep palmar tumors of the hand between January 1998 and June 2015 were evaluated. Tumors and tumor-like pathologies of the deep palmar space of the hand were retrospectively evaluated according to age, gender, localization, preoperative symptoms, size, site, treatment methods, histopathology, and early and late complications. Statistics and data analyses were also performed. RESULTS: All 43 pathologies were benign, and histopathologic diagnoses were 10 lipomas, 8 ganglions, 5 giant cell tumor of the tendon sheath, 4 schwannomas, 3 hemangiomas, 3 palmar fibromatosis, 2 epidermal cysts, 2 neurofibroma, 1 angiolymphoid hyperplasia with eosinophilia, 1 granuloma, 1 calcifying aponeurotic fibroma, 1 digital fibroma, 1 foreign body granuloma, and 1 lipofibromatous hamartoma. The most common complication was temporary numbness and paresthesias of the digits. Marginal excision was performed in 40 patients, excision with nerve grafting in 2 patients (with neurofibroma) and carpal tunnel release in one patient with lipofibromatous hamartoma. CONCLUSION: In the deep palmar space of the hand, pathologies are closely associated with tendons, muscles, and neurovascular structures. Preoperative magnetic resonance imaging is helpful for the preoperative diagnosis, evaluating tumor extension, and successful surgical planning. Level of Evidence: IV Therapautic.

Correlations between ultrasonography findings and surgical findings in patients with refractory symptoms after primary surgical release for carpal tunnel syndrome.

OBJECTIVE: Surgical carpal tunnel release is very effective for symptom relief in carpal tunnel syndrome, and it remains the preferred choice of treatment. However, refractory symptoms following surgical release are not uncommon. We aimed to assess the usefulness of ultrasonography for determining the potential causes of ongoing symptoms following surgical release. METHODS: This retrospective study included 34 patients (32 women; mean age, 54.7±16.65 years; range: 30 to 81 years) with carpal tunnel syndrome who underwent surgical carpal tunnel release. RESULTS: A pathology related to the cause of the ongoing symptoms was detected by ultrasonography in 25 (74.5%) patients. The most common pathological findings were median nerve swelling (70.6%), incomplete transection of the transverse carpal ligament (23.5%) and perineural fibrosis (17.6%). CONCLUSION: In the majority of the patients the pathology related to the ongoing symptoms was detected by ultrasonography, suggesting that ultrasonography could be used as a complementary imaging method for identifying the causes of failure following surgical carpal tunnel release. Detection of an ongoing pathology might help clinicians in managing persistent disease cases and aid in planning an exploration.

Sonographic assessment of transverse carpal ligament after open surgical release of the carpal tunnel.

OBJECTIVE: The aim of this study was to sonographically evaluate the anatomy of the transverse carpal ligament (TCL) after open surgical release in the treatment of carpal tunnel syndrome (CTS) and to establish new ultrasonographic criteria for the completeness of TCL release. METHODS: Thirty-six patients who underwent open surgical release for CTS were recruited prospectively. Patients were evaluated with physical examination and ultrasonography before and after the operation. RESULTS: All patients' symptoms resolved after surgery. TCL was found to be diffusely thickened and to have lost its smooth form after surgery. Postoperative TCL thickness showed a statistically significant increase when compared with preoperative values (p<0.05). CONCLUSION: Sonography is a capable imaging method for assessment of the TCL after open release surgery. In addition, ultrasound may be considered as a complementary tool to exclude diagnosis of incomplete transection of TCL in patients with persistent symptoms.

The effect of medial side repair in terrible triad injury of the elbow.

OBJECTIVE: The aim of this study was to evaluate the effect of surgical repair of the medial collateral ligament and ulnar nerve release in cases of terrible triad injuries of the elbow. METHODS: This study included 16 patients (average age: 34 years) who underwent surgery following a diagnosis of terrible triad injury of the elbow between 1996 and 2007. Average follow up was 34.5 months. In all cases, the radial head was first fixed or replaced and the anterior capsule/coronoid complex and lateral collateral ligament were repaired. The medial side of the elbow was addressed (medial collateral ligament repair and ulnar nerve release) in 8 cases and not addressed in the remaining 8 cases. Range of motion, pain, stability, ulnar nerve symptoms, functional Mayo Elbow Performance Index, and Disabilities of the Arm, Shoulder and Hand scores were documented. Serial X-rays were used to confirm ulnohumeral arthritis and development of ectopic calcification. Ultrasonography or MRI was used to detect ulnar nerve entrapment. RESULTS: Range of motion was slightly more limited in cases where the medial side was not addressed. Ulnohumeral range of motion and flexion degrees were higher in the cases where the medial side was addressed (p<0.05). Serial X-rays demonstrated impending ectopic calcification located at the proximal insertion of medial collateral ligament in patients who did not undergo medial side repair. MRI or ultrasonography confirmed these findings, revealing swollen displaced nerves resembling findings similar to cubital tunnel syndrome. CONCLUSION: Ulnar neuropathy is a common complication after medial collateral ligament injury and prophylactic release will facilitate overall results and postoperative patient satisfaction.

Risk factors for occupational hand injuries: relationship between agency and finger.

BACKGROUND: The aim of this study was to define the risk factors for occupational hand injuries and explore the relationship between the machines and the fingers injured, based on the records of a hospital in Turkey specialized in hand and microsurgery. METHODS: Five thousand twenty seven occupational hand injuries treated at a hand and microsurgery hospital between 1992 and 2005 were included in the study. All the injuries were retrospectively recoded according to ICD-10, (ICECI) and ILO recommendations. Logistic regression and chi-square for trend analysis were used to evaluate the risk factors for occupational injuries. RESULTS: The most frequent injuries were traumatic amputation of wrist and hand (53.2%), open wound of wrist and hand (46.3%). Considering all injuries, 60.9% of agricultural machines, 52.7% of metal working machines, 54.7% of transmission machinery, and 42.8% of wood and assimilated machines affected the right hand. Powered wood cutters, presses, planning and milling machines, and machine belts were the most frequent five machines involved in injuries, each having a different finger pattern. The proportion of machinery among all hand injuries was significantly decreasing with time. CONCLUSION: A stricter and more frequent supervision of the use of protective equipment and prohibition of the purchase of machinery not complying with the regulations could contribute to the prevention of hand injuries.

Epidemiology of injuries treated at a hand and microsurgery hospital.

OBJECTIVES: The aim of this study was to evaluate the epidemiology of injuries treated at a hand and microsurgery hospital between 1992 and 2005. METHODS: This is a descriptive retrospective study based on medical records of a hand and microsurgery hospital in Izmir for the years 1992-2005. A total of 8,946 injuries involving 8,817 patients were included. Data on diagnosis were recorded according to ICD-10. Intent, activity when injured, mechanism of injury, object/substance producing injury, and place of injury were recoded according to International Classification of External Causes of Injury (ICECI). RESULTS: The most common types of injury were amputations (32.3%), fractures (23.7%), and open wounds (19.9%) of the wrist and hand. Most injuries were sustained by males; 28.4% of injuries occurred during summer. According to activity, 76.3% were injured during paid work, 10.4% during transportation, 9.1% during unpaid work, and 3.8% during leisure time sports and exercise. Injuries most commonly occurred while operating a machine. The risk of hand injury was elevated in those younger than 35 years of age, males, persons outside Izmir province, and in Social Security Instution (SSI) insured workers (p<0.001). The riskiest activity for hand injuries was paid work. Compared to baseline, the risk of hand injuries was 29 times [95% confidence interval (CI) 16.36-50.40] as high in industrial or construction areas, and 50 times (95% CI 17.29-143.96) as high in commercial places CONCLUSION: Hand injuries are important because of their consequences, such as permanent disability and their high treatment costs. This study points out many important risk factors, and has contributed the development of hypotheses about injury types, under-notification of occupational injuries, and child labour. The inclusion of medical records from such specialized hospitals into national databases will aid in the prevention of these injuries, and induce developments in diagnosis and treatment.

Ultrasonographic evaluation of the iatrogenic peripheral nerve injuries in upper extremity.

The aim of our study is to assess the efficiency of the ultrasonography (US) in the diagnosis of peripheral nerve injury. This study includes nine patients (six radial, one median and two posterior interosseous (PIO) nerves) with peripheral nerve injury diagnosed by clinical and electrophysiological methods in the last 3 years. Preoperatively, an ultrasonographic examination was performed and correlated with physical exam and surgical findings. Five patients, who were diagnosed as peripheral nerve transection by US, underwent surgery. The ultrasonographic findings were concordant with the intraoperative findings. Axonal swelling alone was found in the remaining three patients, who were treated conservatively because of preserved nerve continuity without display of nerve compression. In one patient, we were unable to visualize the nerve due to obesity and soft tissue edema. High-resolution US provide morphological information about the exact location, intensity and extent of the nerve injuries, facilitating the preoperative diagnosis. Thus, US may be a useful method for planning optimal treatment strategy in especially iatrogenic nerve injuries.

[Long-term results of major upper extremity replantations].

OBJECTIVES: The aim of this study was to evaluate long-term clinical and functional results of major upper extremity replantations. METHODS: We retrospectively evaluated 26 male patients (mean age 27 years; range 3 to 69 years) who underwent major upper extremity replantations and had a mean follow-up of 11.3 years (range 5 to 19 years). The levels of the replantations were transmetacarpal (n=6), wrist (n=4), forearm (n=5), elbow (n=4), and arm (n=7). Amputations were of clean-cut, crush, and avulsion types in seven, eight, and 11 patients, respectively. Secondary operations were performed in 19 patients. Functional results were assessed using the Chen's criteria and the Turkish version of the DASH questionnaire (Disabilities of the Arm, Shoulder and Hand) was administered. RESULTS: The mean surgical shortening was 37.2 mm, and the final mean radiographic shortening was 52.2 mm. The mean grip and pinch strengths on the affected side were 12.3 kg and 3.6 kg, compared to the strengths of 37.6 kg and 8.7 kg on the normal side, respectively. Monofilament testing showed sensory recovery in 20 patients. Two-point discrimination could be made by 18 patients for the median nerve, and by 17 patients for the ulnar nerve. According to the Chen's criteria, the results were very good or good in 17 patients (65.4%), moderate in three patients (11.5%), and poor in six patients (23.1%). Functional results were correlated with the level (r=0.71) and type (r=0.65) of injury, with injuries at the elbow level and avulsion injuries being associated with a worse outcome. The mean DASH score was 6.7 (range 0 to 32.5) and the mean scores of Chen's grade I-II and grade III-IV patients differed significantly (p<0.05). CONCLUSION: Lower DASH scores show increased satisfaction of the patients and improved use of their replanted extremities as the helper arm whereby functional deficiency is somewhat compensated.

[Comparison between two mini incision techniques utilized in carpal tunnel release]. / Açik karpal tünel gevsetmesinde iki farkli mini kesi yönteminin karsilastirilmasi.

OBJECTIVES: We compared two mini skin incision techniques utilized in the treatment of carpal tunnel syndrome (CTS). METHODS: Twenty-seven patients who underwent surgery for CTS were evaluated in two groups according to the site of the mini incision performed for surgical release. A single mini skin incision was performed over the transverse carpal ligament in 12 patients (group 1; 17 hands; 1 man, 11 women; mean age 55 years; range 38 to 66 years), and on the distal side of the ligament in 15 patients (group 2; 17 hands; all women; mean age 54 years; range 34 to 71 years). The two groups were compared with regard to improvement in pain and numbness, rigidity and sensitivity of the scar tissue, time to use the hands, and palmar pinch and grip strengths. The mean follow-up was 26.6 months in group 1, and 23.7 months in group 2. RESULTS: Complete disappearance of symptoms was obtained in 14 wrists (82.4%) in group 1, and in 15 wrists (88.2%) in group 2, with no significant difference between the two groups (p>0.05). Rigidity and sensitivity of the scar tissue were seen in nine wrists (52.9%) in group 1, and in two wrists (11.8%) in group 2 (p<0.05), which lasted 3.5 months and 1.5 months, respectively. In group 2, time to use the affected hand for basic needs (9 days) and normal function (21 days) was significantly shorter, compared to 18 days and 35 days in group 1, respectively (p<0.05). The mean differences of grip and pinch strengths of the two hands were -2.78 kg and -0.60 kg in group 1, and -0.77 and -0.46 kg in group 2, respectively (p>0.05). CONCLUSION: Although both methods of release yield satisfactory results in the mid- and long-term, mini skin incision performed on the distal side of the transverse carpal ligament is associated with less incision-related morbidity.

Elbow arthrolysis in severely stiff elbows.

INTRODUCTION: This study involves the results of open elbow arthrolysis performed on a series of patients having fixed joint contracture. PATIENTS AND METHODS: Eighteen patients were treated with open arthrolysis. Eleven patients had very severely stiff elbows (flexion arc less than 30 degrees ), five patients had severely stiff elbows (31 degrees -60 degrees ) and two patients had moderately stiff elbows (60 degrees -90 degrees ). Fixed flexion deformity was observed in nine patients preoperatively.The mean interval between the trauma and arthrolysis was 14.8 months. The mean age was 27 years. After radiological examination, lateral kocher incision was used on 13 patients, medial and lateral incision on 3 patients, transolecranon approach on 1 patient and anterior and posterior approach on 1 patient. External fixator was applied on four patients. Fasia lata interposition was performed in three patients. Additional procedures were as follows, bone fixation in five patients, bone grafting in two patients, nerve grafting in one patient, subcutaneous ulnar nerve transposition in three patients. The average follow-up time was 47 months. RESULTS: At the final evaluation, the mean extension deficit had improved from 55 degrees to 32 degrees . The mean end flexion increased from 81 degrees to 124 degrees postoperatively. The flexion arc of three patients in whom heterotopic ossification was excised had increased to 65 degrees . Infection was diagnosed in two patients (11%). CONCLUSION: The importance of this study is that the patients have fixed deformities and a long follow-up time. Severely stiff elbow is one of the main indications of open arthrolysis in the patients without muscle atrophy. We suggest sequential arthrolysis as an effective way to obtain good range of motion especially in severe stiff elbows as well as to maintain the ligamantous stability of the elbow joint.

[The effect of dorsal cortical comminution on radiographic results of unstable distal radius fractures treated with closed reduction and K-wire fixation]. / Kapali redüksiyon ve K-teli ile tedavi edilen radius alt uç kiriklarinda dorsal korteks parçalanmasinin radyografik sonuçlara etkisi.

OBJECTIVES: The purpose of this study was to evaluate the effect of dorsal cortical comminution on radiographic outcome of unstable distal radius fractures after treatment with closed reduction and K-wire fixation. METHODS: Forty-two patients were treated with closed reduction and K-wire fixation for unstable, extra-articular distal radius fractures with dorsal angulation. The patients were evaluated in two groups depending on the presence or absence of dorsal metaphyseal cortical comminution observed as a radiopacity on lateral radiographs. Thus, 30 patients (13 males, 17 females; mean age 56 years; range 22 to 77 years) did not have dorsal cortical comminution, whereas 12 patients (8 males, 4 females; mean age 48 years; range 18 to 76 years) did. The mean follow-up period was 8.8 months (range 3 to 106 months) in the former, and 5.5 months (range 3 to 131 months) in the latter groups. Radiographic parameters were compared including palmar tilt measured on lateral, radial inclination and radial length on posteroanterior radiographs obtained before treatment and after union. RESULTS: Radial inclination, palmar tilt, and radial length showed significant improvements in both groups (p<0.05). The results were acceptable in all the patients with achievement of standard reference values. The presence of dorsal cortical comminution did not have any significant effect on radiographic parameters (p>0.05). No significant complications were encountered during the follow-up period. CONCLUSION: Dorsal cortical metaphyseal comminution does not have an adverse effect on radiographic results. Treatment with closed reduction and K-wire fixation is safe and effective even in the presence of dorsal cortical comminution.

[The importance of finger extension test in the diagnosis of occult wrist ganglion]. / Okült gangliyon tanisinda parmak ekstansiyon testinin önemi.

OBJECTIVES: The aim of this study was to evaluate the accuracy of diagnostic tools in comparison with surgical results of occult ganglion cyst of the wrist, which is one of the causes of chronic wrist pain. METHODS: Twenty-five patients (4 males, 21 females; mean age 29 years; range 16 to 46 years) underwent surgery with an initial diagnosis of occult ganglion following unsuccessful conservative treatment. The mean symptom duration was 29 months (range 3 months to 10 years). Diagnosis was based on finger extension test performed in 24 patients. Six patients and 13 patients were assessed by ultrasonography and magnetic resonance imaging (MRI), respectively. Interosseous neurectomy was performed in three patients. The mean follow-up was 31 months (range 6 to 72 months). RESULTS: Occult dorsal ganglion was resected from the scapholunate interval in 22 patients (88%). No ganglion was found in three patients, who had only degeneration of the scapholunate ligament. Finger extension test was positive in 23 patients. One patient with a negative test result was found to have degeneration of the scapholunate ligament. The test yielded two false positive results, one of which was negative by MRI. Surgical confirmation was achieved in 11 patients evaluated by MRI and in four patients evaluated by ultrasonography. Diagnostic accuracy rates for MRI, ultrasonography, and finger extension test were 92%, 66%, and 92%, respectively. Two patients (8%) underwent reoperation for recurrence. None of the patients complained of instability in the late period. Except for one patient, all patients (96%) were asymptomatic at final evaluations. CONCLUSION: Finger extension test is an important diagnostic tool for occult ganglion with 92% accuracy. Both diagnosis and treatment of occult ganglion cysts have become easier by evolving diagnostic tools.

Can we use nerve gliding exercises in women with carpal tunnel syndrome?

This study investigated the effectiveness of nerve gliding exercises used in combination with conservative treatment approaches in patients with carpal tunnel syndrome. A total of 35 hands of 26 patients with carpal tunnel syndrome were divided into 2 groups. Static volar wrist splints were applied to 16 hands in the control group, and these patients were trained to modify their functional activities in accordance with conservative treatment. In the experimental group, nerve gliding exercises were applied to 19 hands that were also treated conservatively. A day-and-night splint, together with the conservative training program, was applied for 6 weeks to both groups. Subsequently, a night splint only was used in both groups, and nerve gliding exercises were continued in the experimental group for the remaining 4 weeks. Pretreatment and posttreatment assessments of pain, sensation, muscle strength, and grip and pinch strength, along with Tinel and Phalen tests, were performed in all cases; electrophysiologic measurements were recorded. Significant progress was detected in both control and experimental groups during the posttreatment phase compared with the initial phase (P < .05). However, when the 2 groups were compared, the experimental group in which nerve gliding exercises were added to conservative therapy approaches demonstrated more rapid pain reduction; these patients also showed greater functional improvement, especially in grip strength (P < .05).
